Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figs. 1-3 It can be known that the utility model provides a kind of technical scheme: a sludge discharge device for sewage treatment, comprising: sedimentation tank 1, water inlet pipe 2 and drain pipe 3, one side of sedimentation tank 1 is connected with water inlet pipe 2, the other side of sedimentation tank 1 is connected with drain pipe 3, the bottom of sedimentation tank 1 close to water inlet pipe 2 is provided with through hole 4, the bottom of sedimentation tank 1 close to through hole 4 is installed with conveying box 5, the outside of conveying box 5 is installed with first motor 6, the rotating shaft end of first motor 6 is connected with spiral conveying roller 7, the bottom of conveying box 5 is provided with sludge discharge port 8, the bottom of conveying box 5 close to sludge discharge port 8 is connected with sealing plate 9 by rotating shaft, bolt is jointly screwed between sealing plate 9 and conveying box 5, the outside of conveying box 5 is connected with connecting block 10, sealing gasket 11 is jointly installed between connecting block 10 and conveying box 5, the bottom of sedimentation tank 1 is installed with air cylinder 12, the telescopic end of air cylinder 12 is connected with partition 13, the both sides of sedimentation tank 1 are jointly welded with support frame 14, the inside of support frame 14 is connected with threaded rod 15 by bearing, the outside of threaded rod 15 is connected with first gear 16, the top of support frame 14 is installed with second motor 17, the rotating shaft outside of second motor 17 is connected with second gear 18, the outside of threaded rod 15 is screw-connected with moving plate 19, the inside close to sedimentation tank 1 of moving plate 19 is installed with trash screen 20, the bottom of moving plate 19 is installed with scraper 21, sliding structure is formed between moving plate 19 and support frame 14, meshing structure is formed between second gear 18 and first gear 16.

[0021] In practice, wastewater can be transported to sedimentation tank 1 through inlet pipe 2 for sedimentation treatment, thereby separating wastewater from sludge. When a large amount of sludge accumulates inside sedimentation tank 1, the second motor 17 can be started. When the second motor 17 rotates forward, it drives the second gear 18 to rotate through the rotating shaft. When the second gear 18 rotates, it can mesh with and drive the first gear 16 to rotate. When the first gear 16 rotates, it can drive the threaded rod 15 to rotate. When the threaded rod 15 rotates, it can drive the moving plate 19 to slide threadedly towards the position above the through hole 4. When the moving plate 19 moves, its top can slide against the support frame 14. At the same time, the moving plate 19 can drive the debris screen 20 and scraper 21 to move. When the debris screen 20 moves, it can push and collect the debris floating on the water surface inside sedimentation tank 1. When the scraper 21 moves, it can... The sludge is pushed by the scraper 21 into the through hole 4. The sludge can fall onto the surface of the partition 13. At this time, the telescopic end of the cylinder 12 can be contracted, so that the telescopic end of the cylinder 12 can drive the partition 13 to move closer to the cylinder 12. The sealing gasket 11 can effectively prevent sludge and sewage from leaking out of the conveying box 5. When the partition 13 moves to a certain extent, the sludge on the partition 13 can fall to the bottom of the inner side of the conveying box 5. Then the telescopic end of the cylinder 12 can be extended, so that the partition 13 can be reset. Thus, the partition 13 can separate the sludge and sewage. The sealing plate 9 at the bottom of the sludge discharge port 8 can be opened by bolts, and the first motor 6 can be started. When the first motor 6 is running, its rotating shaft can drive the spiral conveying roller 7 to rotate. When the spiral conveying roller 7 rotates, it can transport the sludge accumulated inside the conveying box 5.

[0022] See Figs. 1-3 It can be seen that when the sludge is transported to the sludge discharge port 8, the sludge can be discharged from the sludge discharge port 8. Thus, without emptying the sewage inside the sedimentation tank 1, the sludge settled inside the sedimentation tank 1 can be cleaned and discharged. At the same time, the debris net 20 can push and collect the debris floating on the water surface inside the sedimentation tank 1, making it convenient for personnel to clean up the floating debris later.

[0023] See Figs. 1-4 It can be seen that a collection frame 22 is provided on the inner side of the sedimentation tank 1 near the through hole 4. A drain hole 23 is provided through the bottom of the collection frame 22. A connecting column 24 is connected to the inner side of the collection frame 22. A fixing block 25 is connected to the side of the connecting column 24 near the support frame 14. A compression spring 26 is connected inside the fixing block 25. A locking rod 27 is connected to one end of the compression spring 26. A pin 28 is inserted through the inside of the locking rod 27. The pin 28 is L-shaped. The locking rod 27 and the support frame 14 form a plug-in structure.

[0024] In actual implementation, the surface of the sewage in the sedimentation tank 1 usually has sundries floating thereon, and manual cleaning is time-consuming. When the sludge in the sedimentation tank 1 is cleaned and discharged, the trash screen 20 can push the sundries floating on the water surface in the sedimentation tank 1 to above the collecting frame 22, at this time, the pin 28 can be taken out from the clamping rod 27, and then the clamping rod 27 can be pulled to the direction of the connecting column 24. When the clamping rod 27 moves, the compression spring 26 can be compressed. When the compression spring 26 is compressed to a specified degree, the end of the clamping rod 27 can move from one side of the support frame 14 to the other side. At this time, the fixed block 25 can be pulled upward. When the fixed block 25 moves, the connecting column 24 and the collecting frame 22 can be driven to move. In the process of rising, the collecting frame 22 can collect the floating sundries intercepted by the trash screen 20 into the collecting frame 22. The drain hole 23 in the collecting frame 22 can discharge the collected sewage into the sedimentation tank 1, so that only the floating sundries are contained in the collecting frame 22.

[0025] Referring to Figs. 1-4 It can be known that when the collecting frame 22 is removed from the sedimentation tank 1, the floating sundries collected by the trash screen 20 in one place can be quickly collected and taken out from the sedimentation tank 1, thereby saving the time of personnel for salvaging the floating sundries.

[0026] In summary, when the sludge discharging device for sewage treatment is used, the second motor 17 can drive the second gear 18 to rotate through the rotating shaft. When the second gear 18 rotates, the first gear 16 can be driven to rotate through meshing. When the first gear 16 rotates, the threaded rod 15 can be driven to rotate. When the sludge is transported to the sludge discharge port 8, the sludge can be discharged from the sludge discharge port 8, so that the sludge deposited in the sedimentation tank 1 can be cleaned and discharged without emptying the sewage in the sedimentation tank 1. At the same time, the trash screen 20 can push and collect the sundries floating on the water surface in the sedimentation tank 1, which is convenient for personnel to subsequently collect and clean the floating sundries. When the collecting frame 22 is removed from the sedimentation tank 1, the floating sundries collected by the trash screen 20 in one place can be quickly collected and taken out from the sedimentation tank 1 through the collecting frame 22, thereby saving the time of personnel for salvaging the floating sundries. The contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0027] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
