[0003] To address the aforementioned issues, this patent proposes an innovative solution with superior anti-clogging performance to overcome existing technological bottlenecks. Utility Model Content
[0004] The main purpose of this invention is to propose an anti-clogging single-tube sludge suction device, which aims to solve the problems of easy clogging and low cleaning efficiency of traditional sludge suction devices.

A spiral push plate is connected to the outside of the connecting shaft and is rotatably connected inside the sludge suction pipe. Multiple scraper blades are connected to the outside of the lower external side of the connecting shaft and are rotatably connected to the outside of the lower end of the sludge suction pipe.
[0006] Preferably, the lower end of the suction pipe is connected to four connecting seats, and the four connecting seats are fixedly connected to the inner wall of the suction pipe and arranged in a cross shape.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] To achieve the above-mentioned utility model objectives, such as Figures 1-5As shown, this utility model provides an anti-clogging single-pipe sludge suction device, including a sludge suction pipe 1 with its opening facing downwards. A connecting pipe head 2 is connected to the upper front end of the sludge suction pipe 1. A limit frame 3 is connected to the outer side of the upper end of the sludge suction pipe 1. A motor 4 is installed at the center of the upper end of the sludge suction pipe 1. A connecting shaft 5 is rotatably connected to the center of the lower end of the motor 4, and the connecting shaft 5 passes through the inside of the sludge suction pipe 1 and extends to the outer side of the lower end of the sludge suction pipe 1. A spiral push plate 6 is connected to the outer side of the connecting shaft 5, and the spiral push plate 6 is rotatably connected to the inside of the sludge suction pipe 1. Multiple scraper plates 7 are connected to the outer side of the lower end of the connecting shaft 5, and the scraper plates 7 are rotatably connected to the outer side of the lower end of the sludge suction pipe 1. The sludge suction device is used in sedimentation tanks in sewage treatment and industrial wastewater treatment to remove muddy sediment from the bottom of the sedimentation tank. The suction and cleaning process involves inserting the lower end of the suction pipe 1 into the bottom of the sedimentation tank and securing it with the limit frame 3 and bolt assembly. The motor 4 is electrically connected to an external power source via a wiring harness. When the motor 4 is turned on, it drives the spiral pusher 6 and multiple scraper blades 7 to rotate via the connecting shaft 5. The multiple scraper blades 7 scrape the muddy sediment at the bottom of the tank by rotating and move it towards the lower opening of the suction pipe 1. The muddy sediment near the lower end of the suction pipe 1 is pushed upward by the rotation of the spiral pusher 6 and pushed into the connecting pipe head 2. The front end of the connecting pipe head 2 is connected to a sludge discharge pipe via a thread. The muddy sediment pushed into the connecting pipe head 2 is discharged through the sludge discharge pipe, thereby suctioning and cleaning the muddy sediment at the bottom of the sedimentation tank.
[0026] Preferably, the lower end of the suction pipe 1 is connected to four connecting seats 8, which are fixedly connected to the inner wall of the suction pipe 1 and arranged in a cross shape. A limiting seat 9 is connected between the four connecting seats 8. A transposition groove 10 runs vertically through the center of the limiting seat 9. The connecting shaft 5 passes through the transposition groove 10 and is rotatably connected inside the limiting seat 9. A rubber sealing ring is provided between the connecting shaft 5 and the transposition groove 10. A limiting ring 11 is connected to the lower outer side of the connecting shaft 5 and is rotatably connected inside the transposition groove 10. During the rotation of the connecting shaft 5, the lower end of the connecting shaft 5 can be limited by the transposition groove 10 and the limiting ring 11 with the limiting seat 9, and limited by the limiting seat 9 with the suction pipe 1, ensuring the stable rotation of the connecting shaft 5.
[0027] Preferably, a pumping chamber 12 is provided inside the lower side of the connecting shaft 5, and the pumping chamber 12 is located inside the limiting ring 11. A pumping spiral blade 13 is connected inside the pumping chamber 12. Two symmetrically arranged upper connecting pipes 14 are connected to the upper end of the pumping chamber 12, and two symmetrically arranged lower connecting pipes 15 are connected to the lower end of the pumping chamber 12. The two upper connecting pipes 14 and the two lower connecting pipes 15 are arranged in a cross shape and pass through the limiting ring 11. Four symmetrically arranged upper connecting slots 16 are provided at the lower end of the limiting ring 11. The two upper connecting pipes 14 and the two lower connecting pipes 15... The other end of each connecting pipe 15 is connected to one of the four upper connecting grooves 16. Each of the four upper connecting grooves 16 is equipped with an oil guide sealing ring 17. Each of the four upper connecting grooves 16 has a lower connecting groove 18 at its lower end. Each of the four lower connecting grooves 18 is located on the inner wall of the lower end of the transposition groove 10. Each of the four lower connecting grooves 18 has an oil guide pipe 19 at its lower end. The other end of each of the four oil guide pipes 19 is connected to an oil guide cavity 20. Each of the four oil guide cavities 20 is located inside one of the four connecting seats 8. The lower end of each oil guide cavity 20 is connected to multiple telescopic hydraulic holes 21. Each of the multiple telescopic hydraulic holes 21 is slidably connected to... The telescopic hammer rod 22, and multiple telescopic hydraulic holes 21 are all equipped with rubber sealing rings between them. During the sludge suction process, since the pump oil chamber 12, upper connecting pipe 14, lower connecting pipe 15, oil guide pipe 19, oil guide chamber 20, and telescopic hydraulic holes 21 are all filled with hydraulic oil, the connecting shaft 5 can drive the pump oil spiral blade 13 to rotate together, and generate an upward pushing force on the hydraulic oil inside the pump oil chamber 12. When the four upper connecting slots 16 rotate to the upper end of the four lower connecting slots 18, the upper end of the pump oil chamber 12 can pass through the two upper connecting pipes. The oil channel 14 and two oil guide pipes 19 are connected to two oil guide chambers 20. The lower end of the pump oil chamber 12 can be connected to two other oil guide chambers 20 through two lower connecting pipes 15 and two other oil guide pipes 19. At this time, because the hydraulic oil inside the pump oil chamber 12 is pushed upward by the pump oil spiral blade 13, the hydraulic oil inside the two oil guide chambers 20 connected by the two lower connecting pipes 15 will enter the pump oil chamber 12 under the suction of the pump oil chamber 12, and push the hydraulic oil sucked into the pump oil chamber 12 into the two oil guide chambers 20 connected by the two upper connecting pipes 14.
[0028] This causes the two oil guide chambers 20 that extract hydraulic oil to generate negative pressure inside the multiple telescopic hydraulic holes 21 connected at their lower ends, and draws the telescopic hammer rods 22 inside the telescopic hydraulic holes 21 into the connecting seat 8. At the same time, the two oil guide chambers 20 that squeeze in hydraulic oil will generate high pressure inside the multiple telescopic hydraulic holes 21 connected at their lower ends, and push the telescopic hammer rods 22 inside the telescopic hydraulic holes 21 to the outside of the lower end of the connecting seat 8. Since the four upper connecting grooves 16 and the four lower connecting grooves 18 can be connected by the rotation of the connecting shaft 5, and the two upper connecting pipes 14 and the two lower connecting pipes 15 are arranged in a cross shape, the upper and lower ends of the pump oil chamber 12 can alternately connect with the four oil guide chambers 20 inside the four connecting seats 8 arranged in a cross shape, so that the multiple telescopic hammer rods 22 inside the lower end of the four connecting seats 8 can alternately suck in and squeeze out, thereby hammering the mud-like sediment that has clumped at the lower end of the four connecting seats 8, and breaking up the clumped mud-like sediment, preventing the mud-like sediment from clumping and causing blockage at the lower end of the suction pipe 1.
[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
