Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a device for cleaning sludge inside a siphon pipe. Background Technology

[0002] Siphon pipes operate on the siphon principle, allowing sludge in the secondary sedimentation tank to flow along the pipe under atmospheric pressure, thus realizing the transportation process from the secondary sedimentation tank to the sludge return pump station.

[0003] Currently, existing siphon pipes (such as patent publication number: CN212896780U) disclose an automatic venting siphon pipe. Gas forms a gas enrichment zone at the highest point of the siphon pipe. Due to the narrow diameter of the pipe and the fast water flow rate in the narrow diameter zone, a relatively low pressure zone is formed. At this time, the gas in the gas enrichment zone is discharged downstream through the venting hose under the action of pressure difference and discharged from the water outlet end, thereby avoiding the phenomenon of reduced flow rate or interruption caused by gas enrichment at the top of the siphon pipe.

[0004] Sludge is drawn into the sludge return pump room through a circular siphon pipe. Over time, sludge gradually accumulates, which can easily lead to blockage of the siphon pipe, resulting in excessive sludge in the secondary sedimentation tank, causing overload of the reducer, affecting the normal use of the equipment, and making it less practical and needing improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sludge cleaning device for siphon pipes, solving the technical problem of insufficient practicality of existing devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sludge cleaning device for a siphon pipe includes a siphon pipe body and a plurality of water nozzles, each of the water nozzles being fixed at equal intervals on the surface of the siphon pipe body, and further includes;

[0008] At least two delivery pipes are fixedly installed on the surface of the siphon pipe body. Each delivery pipe has a branch pipe on its outer side. A ball valve body is fixedly installed at the end of each branch pipe. A telescopic pipe is fixedly installed at the top of each ball valve body. The same branch manifold is fixedly installed at the top of each telescopic pipe.

[0009] Preferably, the top end of the diversion manifold is provided with a closing valve, the top end of the closing valve is provided with a pump body, both ends of each telescopic pipe are telescopic sleeve structures, the top end of each telescopic pipe is fixedly installed with the same positioning plate, and the inner side of the positioning plate is provided with multiple arc-shaped slots.

[0010] Preferably, two drive columns are fixedly installed at the top of the positioning plate, and a hydraulic pipeline is fixedly installed at the end of each drive column. The top of the two drive columns is fixedly installed with the same fixing plate, and the side end of the fixing plate is fixedly connected to the inner wall of the sedimentation tank.

[0011] Compared with the prior art, the present invention has the following beneficial effects;

[0012] Firstly, high-pressure water jets are sprayed into the siphon pipe body through the water nozzles, flushing in the direction of sludge inflow. The impact force of the high-pressure water can effectively clean the sludge inside the pipe, and can also break up harder sludge, achieving efficient pipe unblocking and ensuring the normal drainage and sludge discharge functions of the siphon pipe. Each set of water nozzles is equipped with a ball valve body, which can be controlled by the operator on the bridge to realize group backwashing operations.

[0013] Secondly, the telescopic tube has a telescopic sleeve structure at both ends. By controlling the drive column to move the positioning plate, the telescopic tube can be stretched or contracted, thereby adjusting the height of the diversion manifold. The position of the equipment components can be flexibly adjusted according to different sedimentation tank liquid levels and siphon pipe installation heights to adapt to various working conditions. The side end of the fixed plate is fixedly connected to the inner wall of the sedimentation tank, providing stable support for the extension and retraction of the drive column.

[0019] This application provides a sludge cleaning device for siphon pipes, which effectively solves the technical problem of insufficient practicality of existing devices. High-pressure water jets are sprayed into the siphon pipe body through water nozzles, flushing in the direction of sludge inflow. The impact force of the high-pressure water can effectively clean the sludge inside the pipe, and can also break up harder sludge, achieving efficient pipe unblocking and ensuring the normal drainage and sludge discharge functions of the siphon pipe. Each set of water nozzles is equipped with a ball valve body, which can be controlled by the operator on the bridge to realize group backwashing operations.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, the technical solution in this application embodiment effectively solves the technical problem of insufficient practicality of existing devices. The overall idea is as follows:

[0022] To address the problems existing in the prior art, this utility model provides a sludge cleaning device for a siphon pipe, including a siphon pipe body 11 and a plurality of water nozzles 12. Each water nozzle 12 is fixed at equal intervals on the surface of the siphon pipe body 11. One end of the water nozzle 12 is connected to a conveying pipe 13, and high-pressure water is conveyed into the water nozzle 12 through the conveying pipe 13.

[0023] The high-pressure water jet generated by the water nozzle 12 cleans the inside of the siphon pipe body 11, flushing along the direction of sludge inflow and cleaning the sludge inside the siphon pipe body 11. Harder sludge can be broken up by the high-pressure water jet, thus unblocking the pipe.

[0024] At least two delivery pipes 13 are fixedly installed on the surface of the siphon pipe body 11. Each delivery pipe 13 has a branch pipe 15 on its outer side. A ball valve body 14 is fixedly installed at the end of each branch pipe 15. A telescopic pipe 16 is fixedly installed at the top of each ball valve body 14. The same diversion manifold 17 is fixedly installed at the top of each telescopic pipe 16.

[0025] The water flow is divided by the manifold 17 and delivered to the branch pipes 15 respectively. At the same time, the end of the branch pipe 15 is connected to the delivery pipe 13 through the ball valve body 14. Each set of water nozzles 12 is equipped with a ball valve body 14 for switching. The operator can control the water flow of each set of water nozzles 12 by controlling the ball valve body 14 on the bridge, and perform backwashing operations in groups.

[0026] A closing valve 18 is provided at the top of the manifold 17, and a pump body 19 is provided at the top of the closing valve 18. By opening the closing valve 18, the interior of the closing valve 18 is open, and the pump body 19 is operated. The impeller inside the pump body 19 delivers water flow into the interior of the manifold 17. Each telescopic pipe 16 has telescopic sleeve structures at both ends. The two ends of the telescopic pipe 16 are respectively connected to the manifold 17 and the branch pipe 15. The telescopic pipe 16 itself can extend and retract to adjust the height of the manifold 17. The same positioning plate 23 is fixedly installed at the top of each telescopic pipe 16. Multiple arc-shaped slots are provided on the inner side of the positioning plate 23. The positioning plate 23 is engaged with the top of the telescopic pipe 16.

[0027] By driving the positioning plate 23 to move, the top end of the telescopic tube 16 moves, and the telescopic tube 16 stretches, which causes the manifold 17 to move upward.

[0028] Two drive columns 22 are fixedly installed at the top of the positioning plate 23, and a hydraulic pipeline is fixedly installed at the end of each drive column 22.

[0029] By controlling the top end of the drive column 22, which is connected to the fixed plate 21, the extension and retraction of the drive column 22 causes the positioning plate 23 to slide, and the positioning plate 23 moves along the vertical direction.

[0030] The top ends of the two drive columns 22 are fixedly mounted with the same fixing plate 21, and the side ends of the fixing plate 21 are fixedly connected to the inner wall of the sedimentation tank.

[0031] Working principle:

[0032] The first step is to operate the pump body 19 and open the closing valve 18. The impeller inside the pump body 19 delivers water to the inside of the diversion manifold 17. The water is diverted in the diversion manifold 17 and delivered to each branch pipe 15 through the telescopic pipe 16. The ball valve body 14 at the end of the branch pipe 15 can be controlled by the operator on the bridge to realize the on / off control of the water flow of each group of water nozzles 12, so that backwashing operations can be performed in groups. When the ball valve body 14 is opened, the water flows into the water nozzles 12 through the delivery pipe 13.

[0033] In the second step, after the water flows into the nozzle 12, it forms a high-pressure water jet that sprays into the siphon pipe body 11, flushing along the direction of sludge inflow. The impact force of the high-pressure water jet removes the sludge inside the siphon pipe body 11. Harder sludge can also be broken up by the high-pressure water jet, thus clearing the pipe. When it is necessary to adjust the height of the manifold 17, the drive column 22 is controlled. The drive column 22 extends and retracts, causing the positioning plate 23 to move vertically. Since the positioning plate 23 is engaged with the top of the telescopic pipe 16, it will cause the top of the telescopic pipe 16 to move, causing the telescopic pipe 16 to stretch or contract, thereby adjusting the height of the manifold 17. The top of the drive column 22 is fixed on the fixed plate 21, and the side of the fixed plate 21 is fixedly connected to the inner wall of the sedimentation tank, providing stable support for the extension and retraction of the drive column 22.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
