Technical Field
[0001] This utility model relates to the technical field of inclined tube sedimentation tanks, specifically an inclined tube sedimentation tank for wastewater pretreatment. Background Technology
[0002] In the wastewater pretreatment section, the inclined tube sedimentation tank plays a key role due to its unique advantages. It utilizes the principle of shallow pool sedimentation, and by setting a large number of inclined parallel tube components in the sedimentation tank, it greatly increases the sedimentation area, shortens the particle settling distance, and significantly improves the sedimentation efficiency. After the wastewater flows in, larger suspended solids, gravel and other impurities quickly settle to the bottom of the tank in the inclined tubes, and the separated clear water is discharged from the top. This effectively removes larger solid impurities from the wastewater, reduces the concentration of suspended solids in the wastewater, reduces the load on subsequent deep treatment, and ensures the stable and efficient operation of the entire wastewater treatment system.
[0003] Currently, in the long-term use of inclined tube sedimentation tanks in wastewater pretreatment sections, impurities in the water tend to adhere to the inner wall of the inclined tube packing, causing blockage. As a result, the water inside the sedimentation tank cannot overflow from the inclined tube, making the inclined tube sedimentation tank unable to operate normally. To address this, we propose an inclined tube sedimentation tank for wastewater pretreatment sections. Utility Model Content
[0004] The purpose of this utility model is to provide an inclined tube sedimentation tank for wastewater pretreatment, which facilitates the cleaning of the inclined tubes inside the sedimentation tank to avoid blockage and ensure the normal operation of the sedimentation tank. Furthermore, the cleaning process does not cause significant disturbance to the upper clear water zone inside the tank, thus ensuring stability during wastewater purification. This solves the problem that in current inclined tube sedimentation tanks used in wastewater pretreatment, impurities in the water easily adhere to the inner wall of the inclined tube packing material during long-term use, leading to blockage and preventing water from overflowing from the inclined tubes, thus hindering the normal operation of the sedimentation tank.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an inclined tube sedimentation tank for wastewater pretreatment, comprising a tank body, wherein inclined tube packing is fixedly installed inside the tank body, a movable frame is provided above the tank body, electric cylinders are fixedly installed on the upper surface of the movable frame near the front and rear surfaces, and a lifting plate is fixedly connected to the output end of the electric cylinders, a plurality of inserts are fixedly installed at equal intervals on the lower surface of the lifting plate, a winding roller is rotatably installed inside the movable frame above the lifting plate, a sponge block is provided inside each insert, and a pull rope is fixedly connected to the upper surface of each sponge block, with the end of the pull rope fixedly connected to the outer surface of the winding roller, and a water injection pipe is fixedly connected to the upper surface of the lifting plate above each insert.
[0006] Preferably, a water pump is fixedly installed on the outer surface of the lifting plate, a branch pipe is fixedly connected to the end of the water pump output pipe, and the end of the water injection pipe is fixedly connected to the outer surface of the branch pipe.
[0007] Preferably, a filter is fixedly connected to the end of the water pump inlet pipe.
[0008] Preferably, a sealing ring is fixedly fitted onto the outer surface of each cannula near the lower surface.
[0009] Preferably, a limit ring is fixedly sleeved on the outer surface of the take-up roller at both sides of each pull rope.
[0010] Preferably, a walking track is symmetrically fixedly installed on the upper surface of the pool near the front and rear surfaces, and a wheel frame is fixedly installed on the lower surface of the moving frame near the front and rear surfaces. A driven wheel is rotatably installed on one side of each wheel frame via a driven shaft, and a drive wheel is rotatably installed on the side of each wheel frame opposite to the driven wheel via a drive shaft. A moving motor is fixedly installed on the upper surface of the wheel frame, and the output end of the moving motor is connected to the drive shaft via a drive connection.
[0011] Preferably, a winding motor is fixedly installed inside the movable frame near the winding roller, and the end of the output shaft of the winding motor is fixedly connected to the end of the winding roller.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up a tank body, inclined tube packing, a moving frame, an electric cylinder, a lifting plate, a winding roller, a pull rope, a sponge block, an insert pipe, and a water injection pipe, achieves the effect of facilitating the cleaning of the inclined tubes inside the inclined tube sedimentation tank, avoiding blockage, ensuring the normal operation of the inclined tube sedimentation tank, and preventing significant disturbance to the upper clear water zone inside the tank during the cleaning process, thus ensuring the stability of the sewage purification process. The output end of the electric cylinder drives the lifting plate to descend, causing the insert pipe to be inserted into the inclined tube packing. Water is injected into the insert pipe through the water injection pipe to push the sponge block inside the insert pipe downward and into the inclined tube packing. As the sponge block moves downward inside the inclined tube packing, it removes the blockage inside the inclined tube packing and moves the blockage downward into the tank body, thereby completing the cleaning of the inclined tube packing. At the same time, it does not cause significant disturbance to the upper clear water zone inside the tank body. After cleaning, the winding roller rotates, causing the pull rope to be wound up on the outer surface of the winding roller, and the sponge block moves from inside the inclined tube packing and rises into the insert pipe.
[0014] 2. By setting a limiting ring, this utility model can limit the pull rope wound on the outer surface of the take-up roller, thus preventing the pull rope from deviating. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] Example 1
[0022] like Figures 1-4 As shown, the present invention proposes an inclined tube sedimentation tank for wastewater pretreatment, comprising a tank body 1, an inclined tube packing 3 fixedly installed inside the tank body 1, a movable frame 4 above the tank body 1, the movable frame 4 being n-shaped in side view and spanning above the tank body 1, an electric cylinder 6 fixedly installed on the upper surface of the movable frame 4 near the front and rear surfaces, and a lifting plate 5 fixedly connected to the output end of the electric cylinder 6, a plurality of insertion tubes 18 fixedly installed at equal intervals on the lower surface of the lifting plate 5, a sealing ring 17 fixedly sleeved on the outer surface of each insertion tube 18 near the lower surface, the sealing ring 17 sealing when the insertion tube 18 is inserted into the inclined tube packing 3, a winding roller 7 rotatably installed inside the movable frame 4 above the lifting plate 5, a winding motor 9 fixedly installed inside the movable frame 4 near the winding roller 7, and the output shaft end of the winding motor 9 fixedly connected to the end of the winding roller 7.
[0023] Each insertion tube 18 contains a cylindrical sponge block 16 with conical top and bottom ends to facilitate its entry and exit from the insertion tube 18 and the inclined tube packing 3. A pull rope 21 is fixedly connected to the upper surface of each sponge block 16, with the end of the pull rope 21 fixedly connected to the outer surface of the take-up roller 7. Limiting rings 8 are fixedly fitted on both sides of each pull rope 21 on the outer surface of the take-up roller 7, thus limiting the pull rope 21 as it is wound on the outer surface of the take-up roller 7 and preventing it from deviating. A lifting plate 5 is inserted, and a sealing ring is fixedly installed on the upper surface of the lifting plate 5 at the position where the pull rope 21 passes through. A water injection pipe 20 is fixedly connected to the upper surface of the lifting plate 5 above each insertion pipe 18. A water pump 22 is fixedly installed on the outer surface of the lifting plate 5. A branch pipe 19 is fixedly connected to the end of the output pipe of the water pump 22, and the end of the water injection pipe 20 is fixedly connected to the outer surface of the branch pipe 19. A filter 23 is fixedly connected to the end of the input pipe of the water pump 22. The upper layer of clear liquid inside the pool 1 enters the water pump 22 after being filtered by the filter 23.
[0024] In use, the electric cylinder 6 drives the lifting plate 5 to descend, causing the insertion tube 18 to be inserted into the inclined tube packing 3. Water is injected into the insertion tube 18 through the water injection pipe 20, which pushes the sponge block 16 inside the insertion tube 18 downward and into the inclined tube packing 3. As the sponge block 16 moves downward inside the inclined tube packing 3, it removes the blockage inside the inclined tube packing 3 and moves the blockage downward into the pool body 1, thus completing the cleaning of the inclined tube packing 3. At the same time, it will not cause significant disturbance to the upper clear water area inside the pool body 1. After cleaning, the take-up roller 7 rotates, causing the pull rope 21 to be wound up on the outer surface of the take-up roller 7. Then the sponge block 16 moves up from inside the inclined tube packing 3 and enters the insertion tube 18.

The walking track 2 is I-shaped in side view. Wheel frames 12 are fixedly installed on the lower surface of the moving frame 4 near the front and rear surfaces. The wheel frames 12 are N-shaped in side view. A driven wheel 11 is rotatably installed on one side of each wheel frame 12 through a driven shaft 10. A driving wheel 13 is rotatably installed on the side of each wheel frame 12 away from the driven wheel 11 through a driving shaft 14. The cross-section of the driving wheel 13 and the driven wheel 11 is H-shaped. A moving motor 15 is fixedly installed on the upper surface of the wheel frame 12, and the output end of the moving motor 15 is connected to the driving shaft 14.
[0027] In this embodiment, the mobile motor 15 drives the drive wheel 13 to rotate through the drive shaft 14, thereby driving the mobile frame 4 to move above the pool body 1.
