[0024] Specifically, as Figure 3 shown, a limiting plate 19 is connected to one side of the filter screen plate 3. By setting the limiting plate 19, the operator can easily draw out the filter screen plate 3.
[0025] Specifically, as Figure 3 shown, a rotating shaft 21 is connected to one side of the filtering box 2, a rotating bar 20 is rotatably connected to the rotating shaft 21, and one side of the rotating bar 20 abuts against the outside of the limiting plate 19. By setting the rotating bar 20, the limiting plate 19 can be limited, preventing the filter screen plate 3 from separating from the filtering box 2 and improving the stability of the structural connection during filtration.
[0026] Specifically, as Figure 3 shown, the blanking mechanism includes a partition plate 14, a blocking block 8 is connected to one end of the conveying pipe 5, a bent pipe 9 is connected to one side of the blocking block 8, the partition plate 14 is slidably connected to the blocking block 8, and when the partition plate 14 is docked with the blocking block 8, one end of the conveying pipe 5 is in a sealed state at this time.
[0027] Specifically, as Figure 3 shown, a plug rod 17 and a sealing spring 16 are connected to the partition plate 14, a spring plate 15 is connected to the outside of the blocking block 8, and the other end of the sealing spring 16 is connected to the spring plate 15.
