Detailed Description

The present invention will be further described with reference to the following examples, which are not intended as a limitation to the present invention.

Example (b): the cloth crushing and conveying system comprises a raw material bin 10, a front conveying device 20, a coarse crushing device 30, a rear conveying device 40, a fine crushing device 50 and a pneumatic conveying system which are sequentially connected. The pneumatic conveying system comprises a negative pressure feeding hopper 61 connected with the fine crushing device 50, the negative pressure feeding hopper 61 is connected with a bag-type dust remover 63 through a negative pressure pipe 62, an exhaust port of the bag-type dust remover 63 is connected with a negative pressure fan 64 through the negative pressure pipe 62, and a feed opening of the bag-type dust remover 63 is a finished product bin 65. The lower end of the finished product bin 65 is provided with a sealed discharger 66 and a quick-opening valve 67 in sequence. The coarse crushing device and the fine crushing device can adopt a commercially available cloth crusher, such as a Fukefk 600DF cloth crusher.

The magnetic iron remover 70 is arranged above the front conveying device 20 and the rear conveying device 40, the magnetic iron remover 70 comprises a non-magnetic roller 71, the tangential speed of the low point of the non-magnetic roller 71 is the same as the conveying direction, the non-magnetic roller 71 is connected with a driving device through a transmission structure on the outer circumference, a static electromagnetic device 72 is arranged in the non-magnetic roller 71, a strip brush 73 for cleaning attached metal is further arranged on the outer surface of the non-magnetic roller 71, and a waste tray 76 is arranged below the strip brush 73.
