[0045] When installing the scraper 110 , the connecting rod 130 passes through the first hole 121 and the connecting hole 112 , and the locking block 520 is embedded in the locking groove 114 so that the connecting rod 130 is stably connected to the connecting hole 112 and the scraper 110 is stably connected to the frame 100 .

[0046] Reference Figure 2 and Figure 3 The frame 100 is connected to a dust hood 600, which is arranged at the bottom of the conveyor belt 300. The length direction of the dust hood 600 is consistent with the width direction of the conveyor belt 300, and the dust hood 600 opens toward the conveyor belt 300.

The collecting bag 650 is detachably connected to the exhaust pipe 630 through a clamp.

[0048] After the conveyor belt 300 passes through the scraper 110, it is transferred to the brush roller 610. The brush roller 610 rotates to clean the surface of the conveyor belt 300. At the same time, the vacuum pump 640 sucks air into the dust hood 600, so that a negative pressure is formed in the dust hood 600. The residue cleaned from the surface of the conveyor belt 300 by the brush roller 610 is sucked into the exhaust pipe 630 and collected in the collection bag 650, thereby reducing the residue on the surface of the conveyor belt 300.

[0049] The implementation principle of a filter press with a filter cake collecting device in an embodiment of the present application is as follows: the conveyor belt 300 transfers the filter cake to the movable box 400. When the conveyor belt 300 is transferred to the top of the scraper 110, the scraper 110 scrapes the residue on the surface of the conveyor belt 300, and the scraped residue slides into the movable box 400 along the scraper 110, thereby reducing impurities adhering to the surface of the conveyor belt 300. When the conveyor belt 300 is transferred to the top of the brush roller 610, the second motor 620 drives the brush roller 610 to rotate, and the brush roller 610 cleans the surface of the conveyor belt 300, and the vacuum pump 640 vacuums the dust in the dust hood 600, so that a negative pressure is formed in the dust hood 600, and the residue cleaned from the surface of the conveyor belt 300 is sucked into the vacuum pipe 630, and the residue enters the collection bag 650 along the vacuum pipe 630, thereby further reducing the residue on the surface of the conveyor belt 300 and minimizing the influence of the residue on the operation of the conveyor belt 300.
