摘要
内吸式滤尘器主要除去空气中的纤尘和粉尘。除尘空间是一个长3000mm，直径2000mm的圆笼，含尘空气透过围在圆笼内的滤布由内往外吹，灰尘就被留在了滤布的内表面。为了防止火灾，滤料为WS-1非织造复合滤料。在工作过程中，圆笼是固定不动的。圆笼中心有一个空心轴，电机通过减速器和带轮的减速，速度由每分钟1390r/min变为4.2r/min,带轮装在主轴上，这样主轴的转速就为4.2r/min。轴上装有有吸嘴架，吸嘴架可以跟着主轴做圆周运动，同时吸嘴架和一个丝杠连接，丝杠装在主轴上，主轴通过传动比1:1的齿轮使丝杠自转，即丝杠以相同的转速自转和公转。这样吸嘴架就能在实现圆周运动的同时实现轴向移动。圆笼内环境比较复杂，不可能有效的传递电信号，同时，空气中又有很多易燃的粉尘，所以不能设计电机正反转装置。要想实现吸嘴架的自动往复运动，必须使用往复丝杠，往复丝杠是立体凸轮副的一种形式，就是在丝杠上加工两条螺距相同、旋向相反的螺纹槽，两端用过渡曲线连接。丝杠在旋转过程中，螺旋槽的侧面推动置于螺旋槽内的滑块作轴向往复运动。当丝杠匀速旋转时，滑块除了完成换向动作外还作匀速直线运动。刻下螺距相同但旋向相反的螺纹槽，在螺纹两端的位置用过渡圆弧连接。这样就能实现自动反向，，不需要电机的反转。吸嘴架上有四个吸嘴，每个吸嘴之间的距离是750mm，吸嘴的最大位移为750mm，刚好可以在3000mm的范围内吸尘。

Abstract
This filter is mainly to remove the dust in the air . Filter space is a 3000mm long, 2000mm diameter circle cage, the air with dust through the cloth which glued to the round cage from inside to outside，the dust was left on the inner surface of cloth. To prevent fire, cloth material is WS-1.While the filter is working .Round cage is stationary. There has a hollow shaft in the center of the circle cage, through the deceleration of gear and pulley. Motor speed is reduced from the 1390r/min to 4.2r/min, pulley mounted on the spindle, so the speed of the spindle is 4.2r/min. Shaft fitted with a nozzle holder, nozzle holder can be a circular motion, while the nozzle holder and a screw connection, screw mounted on the spindle, spindle gear through the gear ratio of 1:1 to the screw rotation, the screw The same speed rotation and revolution .This nozzle holder will be able to achieve both circular motion and axial movement .The environment in the circular cage is complex, in which we cannot transfer electrical signals effectively .There are a lot of inflammable dust in the air, we cannot design the motor reversing device .To achieve the automatic reciprocating motion of nozzle holder. We must use the reciprocating screw, reciprocating screw is a form of three-dimensional cam vice, that is, the same screw pitch on the processing of the two, spin thread to the opposite slot, both ends of the connection with the transition curve. Screw in the rotation process, the spiral groove on the side to promote the slider placed spiral groove for axial reciprocating motion. Uniform when the screw rotates, the slider moves in addition to complete things, to make for uniform linear motion. Carved the same pitch but in the opposite thread rotation slot, the position of both ends of the thread connection with the transition arc. This would automatically reverse, do not need to reverse the motor. There are four nozzles in the nozzle holder, the distance between each nozzle is 750mm, and the maximum displacement of the nozzle is 750mm .Three thousand millimeters is just within in the vacuum.
Key words: dust filter、reciprocating screw、round cage、nozzle.
