食物垃圾粉碎机设计毕业论文

    小型物料含有丰富营养成分，且具有较高的食用价值和工业价值。本课题的设计，对发展小型物料深加工，增加财政收入，帮助山区农民脱贫致富将起到积极的推进作用。

    本设计以增加粉碎能力和筛分效率入手，要设计一种高效、低耗、结构简单、操作方便、使用安全的小型物料食品垃圾粉碎机。我的设计思路为：制定方案—选择功率—设计带传动—设计粉碎室宽度、转子直径—进行细节方面的设计（包括轴、筛子、锤片选择、轴承密封装置、机架、连接件等）—进行轴、键的强度校核—画零件图和装配图—编写说明书。

该食品垃圾粉碎机结构简单，粉碎室比较窄，生产率比较高主要包括转子、锤片、主轴、喂料口、闸板、筛子、粉碎室、机架等部分，以小功率的电动机为动力源，采用带传动，利用高速旋转的锤片对进入粉碎室的物料进行反复锤击，加上转子的旋转离心力作用，使物料在粉碎室与筛片问相互撞击摩擦，利用筛片孔的直径控制加工产品粒度，最后粉碎成细0.1—2mm的小粉末，粉碎后的颗粒通过筛片进入出粉管经出料口排出。

 

 

 

 

    Small materials are rich in nutrients and have high food value and industrial value. The design of this subject, the development of small materials deep processing, increase revenue, to help mountain farmers get rid of poverty will play a positive role in promoting.

    The design to increase the crushing capacity and screening efficiency to start, to design a high efficiency, low consumption, simple structure, easy operation, the use of safe small material food waste grinder. My design ideas are: to develop the program - to select the power - to design the belt drive - to design the crushing chamber width, the rotor diameter - to carry out the details of the design (including shaft, sieve, hammer selection, bearing seals, racks, - to carry out the axis, the key strength of the check - drawing parts and assembly drawings - the preparation of the manual.

The food waste grinder has the advantages of simple structure, relatively narrow crushing chamber, high productivity, including rotor, hammer, spindle, feed mouth, gate, sieve, crushing chamber, rack and so on, with low power motor as the power source , Using the belt drive, the use of high-speed rotation of the hammer to enter the crushing chamber of the material repeated hammering, coupled with the rotor rotation of the centrifugal force, so that the material in the crushing chamber and the screen to ask the impact of friction, the use of screen hole diameter control Processing product size, and finally crushed into small 0.1-2mm small powder, crushed particles through the sieve into the powder pipe discharged through the discharge port.
