变频调速磁性皮带喂料器的设计学生姓名：黄光鑫 班级：0881054指导老师：张绪坤摘要：喂料器是用于向管道内均匀添加物料的设备，它在粮食加工行业、饲料工业中广泛应用。它主要用于输送原料，同时能清除原料中的铁性杂质，以保证机器设备的正常运行，延长设备使用寿命。因此，设计制造不易堵塞，输送量可在一定范围内调整的磁性皮带喂料器，在粮食加工，饲料生产等行业中有着重要的意义。变频调速磁性皮带喂料器是在带式输送机为基础上，配上可进行磁选的永磁滚筒和可调速的变频器改造而成的。带式输送机是一种摩擦驱动以连续方式运输物料的机械。它既可以进行碎散物料的输送，也可以进行成件物品的输送。除进行纯粹的物料输送外，还可以与各工业企业生产流程中的工艺过程的要求相配合，形成有节奏的流水作业运输线。而永磁滚筒则是在传统的传动滚筒上进行改造的，使其具有磁选的功能。其中变频器是应用变频技术与微电子技术，通过改变电机工作电源频率方式来控制交流电动机转速的电力控制设备。 该喂料器的特点是能够变频调速和磁选。喂料器设计主要分为两步，第一步简单介绍了带式输送机的一些主要零部件，并对该喂料器的零部件进行了设计和计算；第二步对该喂料器进行了总体设计，其中有永磁滚筒的设计，并且对变频调速系统进行了设计。关键字：变频调速 磁性皮带 喂料器 带式输送机指导老师签名：The design of Frequency conversion magnetic belt feeder Student name: huang guangxin Class:0881054 Supervisor: zhang xukunAbstract:. The feeder is the equipment used to add material into the pipeline evenly. Its widely used in the food processing industry and feed industry . Its mainly used to transport raw material. And it can remove impurities of metal in the material in order to ensure the normal operation of the machine equipment, prolonging the service life of equipment. Therefore, its significative to design and manufacture the magnetic belt feeder of not easy jamming and throughputing in a certain area of adjustment for the food processing, feed production, and other industries.The frequency conversion magnetic belt feeder is based in the belt conveyor, matched up with the permanent magnetic cylinder that can separate the metal and the speed of the converted frequency converter. Belt conveyor is a mechane of transferring material in a way of friction drive. It can convey not only the broken material but also pieces of items. Besides the material conveying, it still can be fitted with the requirement of the crafting process in the process flow of industrial enterprise production, to form the rhythmic transport Line of flow operation. The permanent magnet roller is changed in the base of traditional transmission roller to make it have the function of the magnetic separation. And the inverter is applied with the technology of frequency conversion and microelectronics technology.Its the equipment to control the speed of the alternating-current motor by changing the working frequency of the motor power. The feeder is characteristic of changing the speed by changing the frequency and magnetic separation.The design of feeder are divided into two parts. Firstly, some main components of the belt conveyor is introduced simply , and the parts of the feeder were designed and calculated. Then the whole design of the feeder is done, including the design of permanent magnet roller and the system of frequency conv
