篦冷机的设计 篦式冷却机(以下简称篦冷机)是水泥厂烧成系统中的一个极其关键的设备,其功能是冷却、输送熟料同时具有高冷却效率、高热回收率和高运转率。篦冷机接受来自回转窑的高温熟料,在冷却热回收过程中,在篦床的高温热端区采用高效控制流技术充分考虑料层的阻力及分布利用区域可调方式对熟料进行冷却,提高了熟料的骤冷效果和二、三次风温度,降低了出料温度,且热回收效率和设备的运转率也得到了提高,确保了烧成系统的稳定性和高运转率。篦冷机主要由固定篦床、供风管路系统、传动轴组件、上下壳体、活动篦床、密封板、挂链装置、出料口装置、篦护板、干油集中润滑系统、液压传动装置、熟料破碎机、托轮装置、挡轮装置、喷装置、空气炮装置、灰斗锁风阀、风机、自动控制和报警装置等组成。械工业是国民的装备部，是为国民经济提供装备和为人民生活提供耐用消费品的产业。不论是传统产业，还是新兴产业，都离不开各种各样的机械装备，机械工业所提供装备的性能、质量和成本，对国民经济各部门技术进步和经济效益有很大的和直接的影响。机械工业的规模和技术水平是衡量国家经济实力和科学技术水平的重要标志。因此，世界各国都把发展机械工业作为发展本国经济的战略重点之一。机械工程的服务领域广阔而多面，凡是使用机械、工具，以至能源和材料生产的部门，都需要机械工程的服务。概括说来，现代机械工程有五大服务领域：研制和提供能量转换机械、研制和提供用以生产各种产品的机械、研制和提供从事各种服务的机械、研制和提供家庭和个人生活中应用的机械、研制和提供各种机械武器。 不论服务于哪一领域，机械工程的工作内容基本相同，主要有：建立和发展机械工程的工程理论基础。例如，研究力和运动的工程力学和流体力学；研究金属和非金属材料的性能，及其应用的工程材料学；研究热能的产生、传导和转换的热力学；研究各类有独立功能的机械元件的工作原理、结构、设计和计算的机械原理和机械零件学；研究金属和非金属的成形和切削加工的金属工艺学和非金属工艺学等等。 研究、设计和发展新的机械产品，不断改进现有机械产品和生产新一代机械产品，以适应当前和将来的需要。机械产品的生产，包括：生产设施的规划和实现；生产计划的制订和生产调度；编制和贯彻制造工艺；设计和制造工具、模具；确定劳动定额和材料定额；组织加工、装配、试车和包装发运；对产品质量进行有效的控制。机械制造企业的经营和管理。机械一般是由许多各有独特的成形、加工过程的精密零件组装而成的复杂的制品。生产批量有单件和小批，也有中批、大批，直至大量生产。销售对象遍及全部产业和个人、家庭。而且销售量在社会经济状况的影响下，可能出现很大的波动。因此，机械制造企业的管理和经营特别复杂，企业的生产管理、规划和经营等的研究也多是肇始于机械工业。 机械产品的应用。这方面包括选择、订购、验收、安装、调整、操作、维护、修理和改造各产业所使用的机械和成套机械装备，以保证机械产品在长期使用中的可靠性和经济性。机械产品的应用。这方面包括选择、订购、验收、安装、调整、操作、维护、修理和改造各产业所使用的机械和成套机械装备，以保证机械产品在长期使用中的可靠性和经济性。研究机械产品在制造过程中，尤其是在使用中所产生的环境污染，和自然资源过度耗费方面的问题，及其处理措施。这是现代机械工程的一项特别重要的任务，而且其重要性与日俱增。机械的种类繁多，可以按几个不同方面分为各种类别，如：按功能可分为动力机械、物料搬运机械、粉碎机械等；按服务的产业可分为农业机械、矿山机械、纺织机械等；按工作原理可分为热力机械、流体机械、仿生机械等。另外，机械在其研究、开发、设计、制造、运用等过程中都要经过几个工作性质不同的阶段。按这些不同阶段，机械工程又可划分为互相衔接、互相配合的几个分支系统，如机械科研、机械设计、机械制造、机械运用和维修等。 这些按不同方面分成的多种分支学科系统互相交叉，互相重叠，从而使机械工程可能分化成上百个分支学科。例如，按功能分的动力机械，它与按工作原理分的热力机械、流体机械、透平机械、往复机械、蒸汽动力机械、核动力装置、内燃机、燃气轮机，以及与按行业分的中心电站设备、工业动力装置、铁路机车、船舶轮机工程、汽车工程等都有复杂的交叉和重叠关系。船用汽轮机是动力机械，也是热力机械、流体机械和透平机械，它属于船舶动力装置、蒸汽动力装置，可能也属于核动力装置等等。19世纪时，机械工程的知识总量还很有限，在欧洲的大学院校中它一般还与土木工程综合为一个学科，被称为民用工程，19世纪下半叶才逐渐成为一个独立学科。进入20世纪，随着机械工程技术的发展和知识总量的增长，机械工程开始分解，陆续出现了专业化的分支学科。这种分解的趋势在20世纪中期，即在第二次世界大战结束的前后期间达到了最高峰。由于机械工程的知识总量已扩大到远非个人所能全部掌握，一定的专业化是必不可少的。但是过度的专业化造成知识过分分割，视野狭窄，不能统观和统筹稍大规模的工程的全貌和全局，并且缩小技术交流的范围，阻碍新技术的出现和技术整体的进步，对外界条件变化的适应能力很差。封闭性专业的专家们掌握的知识过狭，考虑问题过专，在协同工作时配合协调困难，也不利于继续自学提高。因此自20世纪中、后期开始，又出现了综合的趋势。人们更多地注意了基础理论，拓宽专业领域，合并分化过细的专业。械工程以增加生产、提高劳动生产率、提高生产的经济性为目标来研制和发展新的机械产品。在未来的时代，新产品的研制将以降低资源消耗，发展洁净的再生能源，治理、减轻以至消除环境污染作为超经济的目标任务。人类现在已能上游天空和宇宙，下潜大洋深层，远窥百亿光年，近察细胞和分子。新兴的电子计算机硬、软件科学使人类开始有了加强，并部分代替人脑的科技手段，这就是人工智能。这一新的发展已经显示出巨大的影响，而在未来年代它还将不断地创造出人们无法想象的奇迹。人类智慧的增长并不减少双手的作用，相反地却要求手作更多、更精巧、更复杂的工作，从而更促进手的功能。手的实践反过来又促进人脑的智慧。在人类的整个进化过程中，以及在每个人的成长过程中，脑与手是互相促进和平行进化的。Design of grate cooler Institute of Aviation Technology Liu xin Ya introduced a concurrent engineering, agile manufacturing and sophisticated production, and other advanced manufacturing technology and the characteristics of the development of machine tools in the portfolio of applications, how to deepen and extend the application of specific measures.In the machine tool industry, with the social demands of the continuous improvement of products, along with the growing competition in the market to meet user requirements, including the improvement of product quality, shorten production cycles, reduce costs, improve service and win market has become a breakthrough. In order to achieve this goal and win market, it should be the introduction of modern and advanced manufacturing technology: concurrent engineering, agile manufacturing and sophisticated production, in order to promote the development of combination machine.Concurrent Engineering is also known as concurrent engineering, integrated, parallel to optimize product design and its related processes (including manufacturing and support) system approach, which guide the product development staff began to consider a product from concept to design to the demise of throughout the life cycle of all the factors, including quality, cost, programming and user needs.Concurrent Engineering is the first to shorten product development cycles as a means to develop. Products will be characterized by the development, production engineering involved in the acts broken down into a series of tasks, such as market analysis, design, process design, production plans and equipment purchases, processing, quality assurance, testing and after sales service. These sub-tasks as far as possible and consider synchronous parallel to achieve improved design to shorten the cycle and improve quality, reduce costs, optimize the design purpose. It stressed that integrated, coordinated and parallel, namely: (1) management, design, production, and service of all project-related personnel and product information integration as a whole, and stressed that all relevant departments and the interests of the overall goal line (2) to the establishment of a competent and reasonable charge of the project personnel structure of the working group coordinated management model, by the Working Group in the ministries responsible for project elements, and the promotion of the coordination of tasks, (3) parallel processing stages of the work. According to the project in the different tasks of the linkages between the different ministries mandate of the elements of the work process can be completely overlap or duplication. In accordance with these principles, formulate a reasonable, and optimize the work plan, and the location in which the necessary settings assessment, the Working Group by the project implementation so that all sub-tasks in parallel, to move forward in an orderly manner, so as to ensure the smooth implementation of the whole project .According to the traditional methods of work, the work of the various stages in a row serial. In such a product development approach, divorced from each other at various stages, are not related, resulting in increased design error, and difficult to discover such a design rework, to lengthen the development cycle, adding to the costs.Parallel working methods used, the process will be integrated with parallel consideration, the work can be carried out duplication. Problems can be promptly coordinate the changes so that the follow-up stage left to And costs. Thus, the application of concurrent engineering can significantly shorten the product development cycle, reduce costs, it is suitable for the development of professional portfolio machine.Concurrent engineering methods will be applied to product development, the effect was very significant. March 1997, Beijing Institute of Aviation Technology with a motorcycle design and manufacturing plants to sign the 6-crank machine project contract for delivery end of the year, and the requirements of machine tools in the past quite different. In the project using a concurrent engineering approach, in parallel, cross-operation , greatly reducing the design, manufacture period, the successful completion of the tasks.Parallel development of the combination of machine specific methods are:(1) the establishment of a multi-composed of professionals to develop working groups. By the Working Group of the specific part of the implementation of the project, members of the Working Group in collaboration division of duties, timely and coordinated in order to achieve optimization of the design. Such as a machine tool demand in the clamping fixture parts to the process of floating, if separate consideration from the mechanical structure to meet this requirement more difficult, complex structure of the fixture. Later, with the hydraulic design of electrical control and coordinate, control procedures proposed amendments to change the order clamping action, adjusting the hydraulic pressure of solutions to meet the requirements of the clamping.(2) in the formulation of programmes, the signing of the contract stage, on the preliminary identified a number of standard components.(3) Multiple Multi-accreditation programme. Machine Tool Technology in determining the overall programme, key components in the overall design process, many times by the Solidworks committee to review the design plan, and put into production before the user in the design plan joint trials. Thus, from the design to take into account the beginning of a process design, tooling design, manufacturing, assembly and other downstream various stages of debugging problems that may arise, thus greatly reducing the number of design changes Rated meet user requirements, to achieve design best.(4) a design pre-release method. Machine overall plans in a formal drawing ago, has been released in stages set by the main structure and the major components of data, process design, tooling design can be carried out ahead of schedule. In the design of the machine tool to determine some components such as fixtures, tools such as the coordination of size, and at the same time began to design and tool fixture, and, also identified slider, mobile workstations and other components, these components have the choice as far as possible Standard components, in the design of its operation will be completed. And the overall design of the various components such as fixtures, and timely coordination between the tool, linked to changes in the size of each other timely coordination so that the size of other relevant drawings are promptly corrected.(5) components in the design of the processing cycle can be long specific parts such as folders, such as casting stereotypes as soon as possible to advancing the process design, production.(6) completion of the various components of a design, process design and ready to enter the production stage. Therefore, the various components of the parts is in the workshop, parallel processing.Adopt this approach, the Working Group 4 were used only four weeks time on the part of generic components such as the slider, mobile platforms and power first went into operation at the same time, the completion of the mechanical design of the machine and outsourcing of orders. Machine tool production process, the various components in the Beijing Institute of Aviation Technology Association, and several manufacturers at the same time. In the machine, installation and debugging, but also several machine at the same time, through these work, and machine tools for the timely delivery of valuable time.Agile manufacturing in the United States of the Caspian Sea, the 21st century manufacturing strategy in the report of a new manufacturing paradigm. After development, the United States lacocca Institute will be defined as: a company that is agile in the market for the unpredictable changes in the competitive environment in the development and prosperity of a capability, that is rapidly changing global market a rapid response capability, with the company computer network and the global production system, the market, competitors to link up in the high-quality, high-performance, low-cost, customer product configuration settings, such as user demand-driven market situation demonstrated a capability. Characterized by the flexible production technology, flexible organization management and professional skills of the staff have integrated into a coordinated, interconnected systems, in order to achieve the strategic goal of reunification, the same industry in different enterprises through joint infrastructure links, past life-and-death competition will become friendly and cooperative competition, thereby changing market faster response. Therefore, this technology is suitable for the development of professional portfolio machine.(1) promote the Agile first modular products, reflected in the composition of the machine is in the machine tool components and the standardization of serialization. Crankshaft Machine Tool in the development and design, can greatly shorten the design cycle, the application of concurrent engineering is a factor, large number of standard components, the application of common components is a key element.(2) In the Agile Manufacturing, must reflect the people and organizations is the most valuable asset. In the production of large quantities, people are always Solidworks solution as manufacture and sale of the crux of the problem, and in Agile Manufacturing, the best use of people is the key to solve the problem, technology is only a method or means. Therefore, the need for the Project Working Group organizational model advocated hard working, give full play to their initiative.Sophisticated production is the United States in the 1990s, Japans Toyota Motor Corporation summed up production management methods on the basis of summing up by the production. It stressed that by improving the production of enterprises in the management of the activities, including the efficiency of various activities and cost accounting, to achieve the fastest speed of response to the market, the lowest cost of production, the optimal product design to design and Manufacturing of products needed by the market. Its features are user-God, a people-centred, as a means to streamline, to zero defect goal.Can be seen from the above analysis, and advanced manufacturing technology in the Beijing Institute of Aviation Technology Portfolio machine has been developed in a number of applications, but still need to further deepen and extend the application. In later work, Should pay attention to the following aspects:(1) Working Group on the further implementation of the project model, a responsibility to the people, by the use of concurrent engineering group responsible for the completion of the way from the machine tool technology programme to design, manufacture, testing and delivery of the work of the staff at the same time strengthen the knowledge and skills training, keep track machine tool industry at home and abroad combination of the latest developments.(2) market changes and the development of pre-study plan at the same time maintain close ties with users, users who regularly visit provides its users with quality after-sales service, and equipment operation and understanding of user needs, in order to improve the design.(3) high-quality products to win customers. Machine Tool in the development portfolio, in addition to enhancing the sense of quality, the new technology, the application of new technology in the market is also an important means. Now users generally require machine efficiency, flexibility, and adapt to small quantities and variety of processing. Portfolio Tool to enhance the efficiency of production and increase in the design sh
