When the positions of the two filter screens 11 need to be switched, the first support portion 23, the sealing plate 19, the first support block 20 and the second support block 21 are driven downward by the first hydraulic telescopic rod 24, and the first support block 20 presses the first support column 13 located above to move downward, so that the first support column 13 passes through between the second arc plate 17 and the first arc plate 16. When the filter screen 11 located above is separated from the drainage hole 4, the filter screen 11 is released. The driving mechanism drives the rotating shell 6, the prism 7 and the fixed column 8 to rotate, and the first supporting column 13 located at the top slides from the first supporting block 20 to the first arc plate 16, and the first supporting column 13 located at the bottom slides from the first arc plate 16, the first baffle plate 25 and the second arc plate 17 to the first supporting block 20 in sequence, and the first supporting portion 23 and the sealing plate 19 are driven to move up to the initial height by the first hydraulic telescopic rod 24, and the first supporting block 20 no longer presses the first supporting column 13 located at the top, and the elastic supporting assembly drives the fixed column 8 and the filter screen 11 located at the top to move up, so that the filter screen 11 moves into the drain hole 4, and then the first hydraulic telescopic rod 24 drives the first supporting portion 23 and the sealing plate 19 to move up, and the second supporting portion 23 and the sealing plate 19 are driven to move up. The support block 21 pushes the first support column 13 located below to move upward. When the second support block 21 moves up to a preset height, the first hydraulic telescopic rod 24 drives the sealing plate 19 and the second support block 21 to move downward again. The second support block 21 no longer supports the first support column 13. At this time, the elastic support assembly drives the fixed column 8 located below to move downward, so that the first support column 13 hits the first arc plate 16, so that impurities on the filter screen 11 located below can be shaken off. When the filter screen 11 needs to be removed, the driving mechanism drives the rotating shell 6 to rotate ninety degrees, so that the fixed column 8 located below drives the first support column 13 to rotate to one side of the first baffle plate 25, and the first baffle plate 25 supports the first support column 13. At this time, the second hydraulic telescopic rod 34 drives the tooth plate 33 to move, and the tooth plate 33 drives the first rotating shaft 31 and the first baffle 25 to rotate through the gear 32, so that the first baffle 25 no longer blocks the first support column 13, and the staff drives the limit plate 30 and the second baffle 28 to move upward, so that the second baffle 28 no longer blocks the sealing cover 27, and the staff drives the sealing cover 27 to rotate relative to the drainage bucket 5 to open the second rectangular hole 26. Since the first baffle 25 no longer blocks and limits the first support column 13 and the fixed column 8 at this time, the staff drives the filter screen 11 and the fixed column 8 to slide relative to the prism 7, so that the prism 7 is separated from the slide groove 9, and the filter screen 11 can be taken out of the drainage bucket 5 through the second rectangular hole 26; The connecting plate 45 and the fixed shaft 43 are driven to move by the third hydraulic telescopic rod 44, and the fixed shaft 43 can drive the truncated table 39 to move in the rotating shell 6. The end of the movable column 41 slides on the inclined surface of the truncated table 39, and the truncated table 39 can support the movable column 41 and the support plate 12 to move relative to the fixed column 8. The support plate 12 pushes the first spring 10 to compress the first spring 10, thereby changing the length of the first spring 10, controlling the pressure applied by the first spring 10 to the fixed column 8 and the filter screen 11, and the second spring 42 is in a stretched state. When the truncated table 39 moves in the opposite direction horizontally, the second spring 42 drives the support plate 12 and the movable column 41 to move in the opposite direction, so that the movable column 41 The end is always in close contact with the inclined surface of the truncated table 39, and the movable column 41 slides in the opposite direction on the inclined surface of the truncated table 39. The second bevel gear 38 is driven to rotate by the first servo motor 37. The second bevel gear 38 can drive the second rotating shaft 35 and the rotating shell 6 to rotate through the first bevel gear 36, and the second rotating shaft 35 and the rotating shell 6 rotate relative to the fixed shaft 43 and the truncated table 39. The movable column 41 rotates around the axis of the fixed shaft 43 and the truncated table 39, and the movable column 41 is stationary relative to the prism 7. The spiral conveying box 1 is supported by the base 49, and the support shaft 46 and the spiral blade 47 are driven to rotate by the second servo motor 48. The spiral blade 47 can convey the sewage mixture in the spiral conveying box 1.
