Description

Technical Field

[0001] The utility model relates to the technical field of municipal pipelines, in particular to a municipal pipeline network anti-blocking and sewage intercepting device. Background Art

[0002] Municipal pipe network engineering is an important part of municipal engineering and an important infrastructure facility in the city. It includes a variety of pipe systems, among which the urban drainage system is an engineering facility system for treating and draining urban sewage and rainwater. Under the sewage and rainwater diversion system, sewage is collected by drainage pipes, sent to sewage treatment plants for treatment, and then discharged into water areas or recycled; rainwater is collected by drainage pipes and discharged into nearby water areas.

[0003] When drainage pipes are draining rainwater, debris such as leaves will enter the rainwater into the pipes. After a long period of accumulation, a large amount of debris will gather and cause blockage in the pipes, making drainage difficult. A Chinese utility model patent with publication number CN217745992U discloses a municipal pipe network anti-clogging sewage interception device, including a water inlet tank, an outer wall of the water inlet tank is provided with a water inlet pipe, a water outlet tank is provided on the top of the water inlet tank, an outer wall of the water outlet tank is provided with a water outlet pipe, two mounting plates are symmetrically fixedly installed on the inner wall of the water inlet tank, a filter barrel is provided between the two mounting plates, a mounting rod is movably installed on the outer wall of the filter barrel, a cleaning brush and two extension rods are fixedly installed on the outer wall of the mounting rod, an electromagnet 1 is fixedly installed on the outer wall of the extension rod at the lower side, two external connecting rings are fixedly installed on the outer wall of the external connecting ring, a connecting groove is provided, a linkage rod is movably installed on the outer wall of the water inlet tank, two movable rods are fixedly installed on the outer wall of the linkage rod, a positioning rotary block movably connected to the connecting groove is fixedly installed on the outer wall of the movable rod, and an electromagnet 2 that attracts the electromagnet 1 is fixedly installed on the outer wall of the positioning rotary block at the lower side. Connect electromagnet 2 and electromagnet 1 to power, hold the linkage rod and rotate it. When the linkage rod rotates, it will drive electromagnet 2 to rotate inside the connecting groove on the external ring. Electromagnet 2 and electromagnet 1 attract each other. When electromagnet 2 rotates, it will drive electromagnet 1 to rotate inside the water inlet tank. At this time, the movable mounting rod will rotate driven by electromagnet 1, and the cleaning brush will rotate on the outer wall of the filter barrel. At this time, the debris adhering to the surface of the filter barrel will be cleaned and dropped by the cleaning brush, thereby avoiding the problem of debris clogging the mesh of the filter barrel and affecting the filtration after the filter barrel is used for a long time.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: during the cleaning process, the cleaning brush will clean off the debris adhering to the surface of the filter barrel, and the fallen debris will still remain in the water inlet tank and cannot be discharged. After long-term use, excessive accumulation of debris will reduce the water flow rate, which is not conducive to the rapid passage of rainwater. Utility Model Content

[0026] like Figure 1-3 As shown, the embodiment of the present application discloses a municipal pipe network anti-blocking sewage interception device, including a treatment tank 10, a filter mesh tube 20, a cleaning water pipe 30, a cleaning brush 42 and a sewage outlet 15. The treatment tank 10 is used to store rainwater in the filtering process, the filter mesh tube 20 filters the rainwater, the cleaning water pipe 30 is arranged in the treatment tank 10 to clean the filter mesh tube 20, the cleaning brush 42 cleans the inner wall of the filter mesh tube 20, and the sewage outlet 15 is used to discharge the cleaned debris.

[0027] An upper bearing 17 and a lower bearing 18 are respectively arranged at the top and the bottom of the treatment tank 10. The outer ring of the upper bearing 17 is fixedly connected to the top of the treatment tank 10, and the inner ring is fixedly connected to the upper part of the filter mesh tube 20. The outer ring of the lower bearing 18 is fixedly connected to the bottom of the treatment tank 10, and the inner ring is fixedly connected to the lower part of the filter mesh tube 20, so that the filter mesh tube 20 can rotate in the treatment tank 10 under the action of external force. An inlet pipe 11 is arranged at the top of the treatment tank 10 above the filter mesh tube 20, and an inlet valve 12 is arranged on the inlet pipe 11, and rainwater enters the treatment tank 10 from the inlet pipe 11. An outlet pipe 13 is arranged on the outer wall of the treatment tank 10, and an outlet valve 14 is arranged on the outlet pipe 13, and the filtered rainwater is discharged from the outlet pipe 13. Under normal working conditions, the inlet valve 12 and the outlet valve 14 are in an open state, and when the filter mesh tube 20 needs to be cleaned, the inlet valve 12 and the outlet valve 14 are in a closed state.

[0028] Specifically, the cleaning water pipe 30 includes an arc plate 34 arranged on the inner wall of the treatment tank 10, and arc end plates 35 are arranged at the upper and lower ends of the arc plate 34. The arc plate 34, the arc end plates 35 and the corresponding inner wall of the treatment tank 10 constitute a water flow channel. A water inlet is provided on the inner wall of the corresponding treatment tank 10, and a water supply pipe 33 is provided on the water supply port. The structure is compact and easy to install. A row of thrust nozzles 32 and a row of flushing nozzles 31 are arranged vertically at intervals on the cleaning water pipe 30. The water supply pipe 33 is connected to an external high-pressure water source to ensure that the water flow ejected by the thrust nozzle 32 and the flushing nozzle 31 has sufficient impact force. The external high-pressure water source can be provided by a high-pressure water pump. The spray direction of the flushing nozzle 31 points to the wall of the filter mesh tube 20, so that the filter mesh tube 20 is fully flushed by the ejected high-pressure water flow. A plurality of spiral blades 21 are arranged at intervals on the outer wall of the filter mesh tube 20 in a circumferential direction. The connection line between the spiral blade 21 and the filter mesh tube 20 is an obliquely arranged arc. The ejection direction of the thrust nozzle 32 points to the adjacent spiral blade 21. The ejected high-pressure water flow impacts the spiral blade 21 to make the filter mesh tube 20 rotate, thereby causing the filter mesh tube 20 to rotate rapidly under the action of the continuous high-pressure water flow. During the rotation process, the blade surface of the spiral blade 21 is always close to the water flow ejected by the thrust nozzle 32, thereby obtaining sufficient thrust to make the filter mesh tube 20 rotate at a high speed.

[0029] A cylinder 40 is vertically arranged on the top of the treatment tank 10. The piston rod of the cylinder 40 passes downward through the top of the treatment tank 10 and is provided with a horizontally arranged fixed rod 41 at the end. Cleaning brushes 42 are respectively arranged at both ends of the fixed rod 41. The cleaning brush 42 is provided with steel wire bristles, and the steel wire bristles contact the inner wall of the filter mesh tube 20. When the filter mesh tube 20 rotates, the filter mesh tube 20 and the steel wire bristles rotate relative to each other, and the steel wire bristles clean up the debris attached to the inner wall of the filter mesh tube 20 and the debris in the mesh of the filter mesh tube 20. At the same time, the fixed rod 41 and the cleaning brush 42 are driven by the cylinder 40 to move slowly from top to bottom, so as to clean the inner wall of the entire filter mesh tube 20. A funnel-shaped drain port 15 is provided at the bottom of the treatment tank 10 below the filter mesh tube 20, and a drain valve 16 is provided at the drain port 15. The debris flushed down by the flushing nozzle 31 in the filter mesh tube 20 and the debris cleaned by the cleaning brush 42 are discharged through the drain port 15. The bottom is funnel-shaped so that the debris can slide downward under the action of the water flow and be completely discharged.

[0030] The use principle of a municipal pipe network anti-blocking sewage interception device in this embodiment is as follows: rainwater enters the treatment tank 10 through the water inlet pipe 11, is filtered by the filter mesh pipe 20 and then discharged from the water outlet pipe 13, and the debris in the rainwater is intercepted by the filter mesh pipe 20 on its inner side. After long-term use, when there are too many debris adhering to the inner wall of the filter mesh pipe 20 and affecting the normal flow of water, the water inlet valve 12 and the water outlet valve 14 are closed, the sewage valve 16 is opened, and the external high-pressure water source is turned on. The high-pressure water flow enters the cleaning water pipe 30 through the water supply pipe 33 and is ejected from the thrust nozzle 32 and the flushing nozzle 31 respectively. The high-pressure water flow ejected by the thrust nozzle 32 impacts the spiral blade 21 to rotate the filter mesh pipe 20, and the high-pressure water flow ejected by the flushing nozzle 31 is ejected onto the filter mesh pipe 20 to flush the filter mesh pipe 20. During the rotation of the filter mesh pipe 20, the steel wire bristles on the cleaning brush 42 clean the debris attached to the inner wall of the filter mesh pipe 20 and the mesh of the filter mesh pipe 20. At the same time, the cylinder 40 drives the fixing rod 41 and the cleaning brush 42 to move slowly from top to bottom, thereby cleaning the inner wall of the entire filter mesh tube 20, and the cleaned debris is discharged from the sewage outlet 15. After the cleaning is completed, the cylinder 40 drives the cleaning brush 42 to reset, the external high-pressure water source and the sewage valve 16 are closed, and the water inlet valve 12 and the water outlet valve 14 are opened to continue the filtering operation.
