Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically to a sedimentation tank inclined tube flushing device. Background Technology

[0002] To increase the sedimentation area of ​​a sedimentation tank within a limited footprint, a set of parallel inclined tubes is typically added to the sedimentation zone. Water flows between the tubes, significantly shortening the settling distance of particles, which then slide into the sludge zone after settling inside the tubes, thus improving sedimentation efficiency. However, after a period of operation, sludge, algae, biofilm, or other sticky substances gradually accumulate inside the inclined tubes, leading to: 1. Reduced effective sedimentation area: The water passage becomes narrower, resulting in a decrease in treatment capacity.

[0003] 2. Increase water flow velocity: Excessive flow velocity will interfere with the sedimentation process, leading to deterioration of the effluent quality (increased turbidity).

[0004] 3. Increased tank load: Excessive sludge accumulation will increase the structural weight and may trigger anaerobic fermentation, producing odor and floating sludge, thus compromising the treatment effect.

[0005] 4. Shortened equipment lifespan: Severe blockage increases the difficulty and cost of cleaning.

[0006] To address the aforementioned issues, we propose a sedimentation tank inclined tube flushing device. Utility Model Content

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example

[0016] like Figures 1 to 3 As shown, the sedimentation tank inclined tube flushing device includes a flushing head 9 and a slide groove 2 fixed on the equipment frame 1. A slide seat 5 is slidably connected in the slide groove 2. A bracket 7 is fixed on the slide seat 5, and a column tube 8 is slidably connected on the bracket 7. The flushing head 9 is rotatably connected to one end of the column tube 8, and the other end of the column tube 8 is connected to a cap 25. A water pump 4 is fixed on the equipment frame 1, and the outlet end of the water pump 4 is connected to the cap 25 through a water pipe 10. A brush cylinder 16 is sleeved on and rotatably connected to the outer peripheral wall of the column tube 8 near the flushing head 9. A pipe shaft 12 is coaxially fixedly connected to the flushing head 9, and an impeller 13 is fixed inside the pipe shaft 12. The pipe shaft 12 is inserted into the column tube 8 and rotates rotatably inside the column tube 8. A water spray channel 14 is opened on the peripheral wall of the flushing head 9, and the spray direction of the water spray channel 14 forms an angle of 38°-48° with the axis of the flushing head 9.

[0017] In this embodiment, a gear ring 15 is coaxially fixedly connected to the rinsing head 9, a gear ring 2 17 is coaxially fixedly connected to the brush cylinder 16, a gear 18 is rotatably connected to the outer peripheral wall of the column tube 8, the gear 18 is located between the gear ring 15 and the gear ring 2 17 and meshes with both gear ring 15 and the gear ring 2 17, a screw 6 is rotatably connected to the slide groove 2, and the screw 6 passes through and is threadedly connected to the slide seat 5, one end of the screw 6 is connected to the motor 3 for transmission, and the motor 3 is fixed on the equipment frame 1.

[0018] In this embodiment, a reciprocating screw 20 is rotatably connected to the support 7, and the reciprocating screw 20 is arranged parallel to the column tube 8. A protruding rod 21 is fixed on the outer wall of the column tube 8, and the reciprocating screw 20 is slidably connected to the protruding rod 21 through and in a matching manner. A support rod 19 is fixed on the slide block 5, and the reciprocating screw 20 is rotatably connected to the support rod 19. A shaft 23 is rotatably connected to the support rod 19, and one end of the shaft 23 is connected to the reciprocating screw 20 through a bevel gear set 22. The other end is coaxially fixedly connected to a gear 24. A rack 11 is fixed on the slide groove 2, and the rack 11 is arranged parallel to the screw 6. The gear 24 meshes with the rack 11.

[0019] The principle and advantages of this utility model: When flushing the inner wall of the inclined tube in the sedimentation tank, the tilt angle of the equipment frame 1 is adjusted so that the column tube 8 is parallel to the inclined tube. The motor 3 and water pump 4 are started, so that the water pump 4 delivers high-pressure water to the column tube 8 through the water pipe 10. The water is sprayed out from the spray channel 14 of the flushing head 9, and the spray pressure is higher than 8MPa. Since the spray direction of the spray channel 14 is at an angle of 38°-48° with the axis of the flushing head 9, the high-speed water is flushed at an angle to the dirt on the inner wall of the inclined tube, which facilitates the removal of dirt from the inner wall surface and improves the flushing efficiency of the inner wall of the inclined tube. When the motor 3 is working, it drives the screw 6 to rotate, so that the screw 6 drives the slide 5 to slide in the slide groove 2. The slide 5 drives the column tube 8 to be inserted into the inclined tube through the bracket 7. Then, the column tube 8 drives the flushing head 9 to flush the inner wall of the inclined tube from top to bottom, thereby improving the working efficiency.

[0020] As described above, the high-pressure water flow applies torque to the impeller 13 as it flows through the tube shaft 12, causing the impeller 13 to drive the tube shaft 12 and the flushing head 9 to rotate. This allows the flushing head 9 to rotate while being inserted into the inclined tube, improving the flushing efficiency of the inner wall dirt. Furthermore, the rotation of the flushing head 9, through the gear ring 15, gear 18, and gear ring 17, drives the brush cylinder 16 to rotate, allowing the brush cylinder 16 to scrub the inner wall of the inclined tube after flushing, further improving the cleaning effect of the dirt on the inner wall of the inclined tube.

[0021] As described above, while the slide 5 moves, it drives the shaft 23 and its gear 24 to rotate synchronously via the support rod 19. Under the action of the rack 11, the gear 24 drives the shaft 23 to rotate, which in turn drives the shaft 23 to rotate via the bevel gear set 22. This causes the reciprocating screw 20 to rotate, which in turn drives the column tube 8 to reciprocate on the bracket 7 via the convex rod 21. This achieves the simultaneous up-and-down movement of the axial direction of the flushing head 9 while flushing the dirt on the inner wall of the inclined tube from top to bottom. This allows the flushing head 9 and the brush cylinder 16 to thoroughly clean the inner wall of the inclined tube, greatly improving the efficiency and effect of flushing the inclined tube. After flushing, the motor 3 controls the screw 6 to rotate in the opposite direction, causing the screw 6 to drive the slide 5 to slide in the opposite direction within the groove 2. This allows the slide 5 to drive the column tube 8 out of the inclined tube via the bracket 7.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
