内循环式烘干机总体及卸料装置设计

摘  要

    现如今矿物的烘干以及建筑材料的烘干都离不开烘干机的使用。本次设计的烘干机采用的是内循环式的三筒烘干机，这种烘干机不仅结构非常紧凑，而且烘干的效率非常高，同样占地面积也非常小，有效的减少了能耗。内循环式三筒烘干机一般用于对于潮湿程度一定的颗粒类型材料进行烘干，一般包括水泥、黄沙以及高炉矿渣等等。小立度粘物料终水份要求，最终的含水分非常低。物料进入烘干机是最好的烘干情况是不与烘干机筒比粘连。烘干机能承受的气体热交换的最高温度不应该超过750摄氏度，当需要更高的烘干温度是应该将扬料板和内筒的材料换成耐热的钢板。物料通过机器进入未料口后，通过重力的作用在烘干机的入口处被分散均匀进入烘干机，这样就确保了物料在机器里面进行的热交换取得成效。物料进入烘干机后会与热气体相遇，通过顺溜的方式与物料进行接触，将热量通过各种方式传递到物料中，这样就起到了给物料升温并蒸发其水分的作用，是其符合物料的烘干要求并将热气从卸料排气口泄出，物料从卸料口泄出。这种方法适用于很多形式的烘干，方法使用也很方便，有不错的运用前景。

Design of Internal Circulation Dryer and Discharge Device

Abstract

Now the drying of minerals and the drying of building materials are inseparable from the use of dryers. The dryer used in this design is the internal circulation of the three-cylinder dryer, this dryer is not only very compact structure, and the efficiency of drying is very high, the same area is also very small, effectively reduced Energy consumption. Internal circulation three-cylinder dryer is generally used for the wet degree of a certain type of particle type material drying, generally including cement, sand and blast furnace slag and so on. Small vertical viscosity of the end of the material requirements, the final moisture content is very low. The material into the dryer is the best drying condition is not sticky with the drying cylinder. Dryers can withstand the maximum temperature of the gas heat exchange should not exceed 750 degrees Celsius, when the need for higher drying temperature should be the material of the plate and the tube into a heat-resistant steel plate. Material through the machine into the mouth after the material, through the role of gravity at the entrance of the dryer was dispersed evenly into the dryer, thus ensuring the material inside the machine for heat exchange to achieve results. Material into the dryer will meet with the hot gas, through the way to contact with the material, the heat through a variety of ways to pass to the material, so it played to the material temperature and evaporation of its moisture, is its material Of the drying requirements and the hot gas from the discharge exhaust vent, the material from the discharge port leak. This method is suitable for many forms of drying, the method is also very convenient to use, there is a good use of prospects.
