Description

Technical Field

[0001] This utility model relates to the field of sewage pump technology, and in particular to a sewage pump with an automatic rotating cleaning brush at the sewage outlet. Background Technology

[0002] Sewage pumps are widely used in various drainage systems, especially in sewage treatment, industrial wastewater discharge, and agricultural irrigation. With the increasing complexity of the operating environment, sewage pumps face challenges such as high levels of impurities and solids in sewage, which can easily affect their normal operation. Therefore, sewage pumps typically need to be equipped with filtration devices to remove impurities and prevent large particles in the sewage from entering the pump body, thus avoiding blockages and damage.

[0003] However, in existing sewage pumps, the filter screen is usually fixedly installed. Over time, the filter screen easily becomes clogged, affecting the normal operation of the sewage pump. Especially during the cleaning and replacement of the filter, it is often necessary to disassemble and manually clean the filter screen, which not only increases maintenance costs but also prolongs equipment downtime. Furthermore, when sewage pumps are handling wastewater containing large impurities, if the impurities are not effectively broken down, it may lead to pump damage or reduced operating efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sewage pump with an automatic rotating cleaning brush at the sewage outlet, which aims to improve the problem in the prior art that the filter screen needs to be disassembled and manually cleaned, and that if impurities are not effectively broken up, the pump body may be damaged or the working efficiency may be reduced.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sewage pump with an automatic rotating cleaning brush at the sewage outlet, comprising a pump body, a drain pipe fixedly connected to the output end of the pump body, a pump motor fixedly connected to the upper side of the pump body, a connecting shaft fixedly connected to the output end of the pump motor, an impeller fixedly connected to the outside of the connecting shaft, a water inlet pipe fixedly connected to the input end of the pump body, a sealing frame fixedly connected inside the water inlet pipe, a placement groove opened inside the water inlet pipe, a fixed frame slidably connected inside the placement groove, a filter screen fixedly connected inside the fixed frame, a pull rod fixedly connected to the right side of the filter screen, insertion rods fixedly connected to both sides of the fixed frame, the insertion rods slidably connected inside the insertion block, the insertion block fixedly connected to both sides of the outside of the water inlet pipe, a threaded sleeve connected to the outside of the insertion rod, and a cleaning component fixedly connected inside the drain pipe for cleaning the inner wall of the drain pipe.

[0006] As a further description of the above technical solution:

[0007] The cleaning assembly includes a mounting bracket fixedly connected to the inside of a drain pipe. A protective cover is fixedly connected to the right side of the mounting bracket, and a rotary motor is fixedly connected inside the protective cover. A brush is fixedly connected to the output end of the rotary motor.

[0008] As a further description of the above technical solution:

[0009] A fixing plate is fixedly connected inside the water inlet pipe, a fixing cover is fixedly connected to the upper side of the fixing plate, a drive motor is fixedly connected inside the fixing cover, and a crushing component is fixedly connected to the output end of the drive motor. The crushing component is used to crush large impurities.

[0010] As a further description of the above technical solution:

[0011] The crushing component includes a rotating shaft, which is fixedly connected to the output end of a drive motor. A rotating block is fixedly connected to the bottom end of the rotating shaft, and uniformly distributed blades are fixedly connected to the outside of the rotating block.

[0012] As a further description of the above technical solution:

[0013] The brush is slidably connected inside the drain pipe.

[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, sewage is filtered by a filter screen. The screw sleeve is manually rotated to disengage the insert rod, and the pull rod is manually pulled to move the fixed frame and the filter screen. The fixed frame slides inside the sealing frame, disengaging it from the placement groove and the insertion groove. At the same time, the movement of the fixed frame causes the insert rod to disengage from the insertion block. This makes it easy to disassemble and assemble the filter screen, facilitates cleaning of the filter screen, and improves its filtration effect.

A rotary motor 27 is fixedly connected inside the protective cover 26. A brush 28 is fixedly connected to the output end of the rotary motor 27.

[0032] By starting the pump 3, the connecting shaft 4 and impeller 5 are rotated, which in turn drives the sewage into the inlet pipe 6 and the pump body 1, and then into the drain pipe 2 for discharge, facilitating sewage transportation. The sewage is filtered by the filter screen 10. By manually turning the screw sleeve 15 to disengage from the insert rod 13, and then manually pulling the pull rod 11, the fixed frame 9 and the filter screen 10 are moved, causing the fixed frame 9 to slide inside the sealing frame 7 and disengage from the placement groove 8 and the insertion groove 12. At the same time, the movement of the fixed frame 9 causes the insert rod 13 to disengage from the insertion block 14, which facilitates the disassembly and assembly of the filter screen 10. By starting the rotary motor 27, the brush 28 is rotated, causing the brush 28 to slide inside the drain pipe 2, which facilitates cleaning of the drain pipe 2.

[0033] Reference Figure 3 , Figure 4 A fixing plate 16 is fixedly connected inside the water inlet pipe 6. A fixing cover 17 is fixedly connected to the upper side of the fixing plate 16. A drive motor 18 is fixedly connected inside the fixing cover 17. A crushing component is fixedly connected to the output end of the drive motor 18.

[0034] By starting the drive motor 18, the rotating shaft 19, the rotating block 20 and the blade 21 are driven to rotate. The rotating blade 21 uniformly crushes large impurities, thus enabling the crushing and processing of impurities inside the sewage.

[0037] Working Principle: When using this device, starting the pump 3 drives the connecting shaft 4 to rotate, which in turn drives the impeller 5 to rotate, thus drawing sewage into the inlet pipe 6. From there, the sewage enters the pump body 1 and exits through the drain pipe 2, facilitating sewage transport. Once the sewage reaches the inlet pipe 6, starting the drive motor 18 drives the rotating shaft 19 to rotate, which in turn drives the rotating block 20. The rotating block 20 then drives the blade 21, effectively breaking down impurities within the sewage and preventing damage to the sewage pump. The installed filter... The filter screen 10 filters wastewater. By manually rotating the screw sleeve 15, the screw sleeve 15 is disengaged from the insertion rod 13. Then, by manually pulling the pull rod 11, the pull rod 11 moves, causing the fixed frame 9 to move. The fixed frame 9 moves, causing the filter screen 10 to move, allowing the fixed frame 9 to slide inside the sealing frame 7 and disengage from the placement groove 8 and the insertion groove 12. At the same time, the movement of the fixed frame 9 causes the insertion rod 13 to disengage from the insertion block 14, making it easy to disassemble and assemble the filter screen 10, facilitating cleaning and improving its filtration effect. By starting the rotary motor 27, the rotary motor 27 drives the brush 28 to rotate, causing the brush 28 to slide inside the drain pipe 2, facilitating cleaning of the drain pipe 2.
