DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. It should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0029] Reference Figure 1-Figure 6 A waste removal device for a sludge treatment production line includes a filter box 1, which is opened at the top and bottom. A rectangular groove 7 is provided on the top of one side of the filter box 1. The inner walls of both sides of the filter box 1 are slidably connected with side plates 17. The sides of the two side plates 17 close to each other are rotatably connected with the same second rotating shaft 21. The outer wall of the second rotating shaft 21 is fixedly sleeved with a U-shaped frame 19;

[0030] A screening component for screening impurities is arranged inside the U-shaped frame 19;

[0031] A connecting block 9 is fixedly connected to the bottom of the filter box 1 away from the rectangular groove 7. A first rotating shaft 8 is fixedly passed through the interior of the connecting block 9. Both ends of the first rotating shaft 8 are rotatably connected to the same drawer box 4. The drawer box 4 is used to block the bottom of the filter box 1.

[0032] Both sides of the filter box 1 are provided with fixing components for fixing the drawer box 4 .

[0033] In the utility model, the screening component includes a screen 18 and two positioning grooves 26 provided on the inner wall of a U-shaped frame 19. Positioning plates 25 are fixedly connected to both sides of the screen 18. The positioning plates 25 are engaged with the positioning grooves 26, so that the sludge can be poured into the interior of the filter box 1. Then, the cross bar 2 is lifted vertically upward through the operating block 3. The cross bar 2 drives the vertical rod 16 and the side plate 17 to move vertically upward. The side plate 17 drives the screen 18 and the U-shaped frame 19 to move vertically upward. At this time, the impurities are lifted from the interior of the sludge by the screen 18.

[0034] When the drawer box 4 is in the state of being locked, the first clamping rod 13 of the drawer box 4 and the second clamping rod 15 of the drawer box 4 are in the state of being locked.

[0035] In particular, the top of the side plate 17 is fixedly connected with a vertical rod 16 , and the tops of the two vertical rods 16 are fixedly connected with the same cross rod 2 , so as to facilitate lifting the screen 18 .

[0036] In particular, a strip-shaped notch 12 is provided on one side of the filter box 1, and one end of the cross bar 2 slides through the strip-shaped notch 12 and is fixedly connected with the operating block 3, which can be easily operated.

[0037] In particular, an arc-shaped notch 22 is opened on one side of the U-shaped frame 19, and a gear 23 is fixedly sleeved on the outer wall of the second rotating shaft 21. The gear 23 is located inside the arc-shaped notch 22. A rack 11 is fixedly connected to the inner wall of one side of the filter box 1. The rack 11 and the gear 23 are used in conjunction with each other. After the screen 18 moves to a certain height, it can be turned over, thereby discharging internal impurities. At this time, the U-shaped frame 19 continues to move upward, the gear 23 meshes with the rack 11, and the gear 23 starts to rotate. The gear 23 drives the second rotating shaft 21 to rotate, and the second rotating shaft 21 drives the U-shaped frame 19 to rotate. The U-shaped frame 19 drives the screen 18 to rotate, and the screen 18 drives the third rotating shaft 24 to rotate along the arc groove 20. At this time, the screen 18 and the U-shaped frame 19 are inclined, and the impurities above are discharged through the rectangular groove 7. The setting of the inclined groove 6 can facilitate the discharge of impurities, and the setting of the positioning plate 25 and the positioning groove 26 can facilitate the disassembly and replacement of the screen 18.

[0038] In particular, an inclined groove 6 is provided on the bottom inner wall of the rectangular groove 7 to facilitate the rapid discharge of impurities.

[0039] In particular, the third rotating shaft 24 is fixedly connected to both sides of the U-shaped frame 19 , and an arc groove 20 used in conjunction with the third rotating shaft 24 is opened on one side of the side plate 17 to ensure the stability of the movement of the screen 18 inside the two side plates 17 .

[0040] Working principle: When the sludge needs to be filtered, the sludge can be poured into the filter box 1, and then the cross bar 2 is lifted vertically upward through the operating block 3. The cross bar 2 drives the vertical bar 16 and the side plate 17 to move vertically upward, and the side plate 17 drives the screen 18 and the U-shaped frame 19 to move vertically upward. At this time, the impurities are lifted from the inside of the sludge by the screen 18;

[0041] When the side plate 17 moves to one side of the rectangular groove 7, the side plate 17 will first push the first clamping rod 13, the first clamping rod 13 moves horizontally and drives the connecting rod 5 to move horizontally, the tension spring 14 is stretched, the connecting rod 5 drives the second clamping rod 15 to move horizontally, and the second clamping rod 15 is released from the clamping state with the clamping groove 10. At this time, the drawer box 4 rotates around the first rotating shaft 8, and the end of the drawer box 4 close to the first rotating shaft 8 will conflict with one side of the filter box 1, so that the drawer box 4 cannot be turned over too much, and the screened sludge is discharged through the gap between the drawer box 4 and the filter box 1 for easy collection;

[0042] At this time, the U-shaped frame 19 continues to move upward, the gear 23 meshes with the rack 11, the gear 23 starts to rotate, the gear 23 drives the second rotating shaft 21 to rotate, the second rotating shaft 21 drives the U-shaped frame 19 to rotate, the U-shaped frame 19 drives the screen 18 to rotate, the screen 18 drives the third rotating shaft 24 to rotate along the arc groove 20, at this time the screen 18 and the U-shaped frame 19 are inclined, and then the impurities above are discharged through the rectangular groove 7, the setting of the inclined groove 6 can facilitate the discharge of impurities, and the setting of the positioning plate 25 and the positioning groove 26 can facilitate the disassembly and replacement of the screen 18.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
