Description

Technical Field

[0001] The utility model belongs to the technical field of sewage pumps, and in particular relates to a sewage pump. Background Art

[0002] Sewage pump is a kind of centrifugal impurity pump, with many forms: submersible and dry. The most commonly used submersible pump is QW submersible sewage pump, and the most common dry sewage pumps are W horizontal sewage pump and WL vertical sewage pump. It is mainly used to transport urban sewage, feces or liquid containing fiber. Paper scraps and other solid particles.

[0003] Since the medium being transported contains fibers that are easy to entangle or bunch, the flow channel of this pump is easy to be blocked. Once the sewage pump is blocked, the pump body will not work normally, and even burn the motor, resulting in poor sewage discharge. It has a serious impact on urban life and environmental protection. When the sewage pump's delivery pipeline is blocked, it needs to be disassembled and cleaned. Common sewage pumps are generally fixed in an integrated manner, which is troublesome to disassemble and assemble, difficult to maintain, and has a relatively poor anti-blocking effect.

[0004] Therefore, a sewage pump is needed to solve the problem that the sewage pump has poor anti-blocking effect and is not easy to disassemble and maintain. Utility Model Content

The outer wall of the rotating rod 9 is tightly sleeved with a spiral blade 11, and a connecting component 12 is arranged between the guide tube 5 and the water inlet pipe 3; by arranging a filter plate 7 inside the guide tube 5 to isolate larger impurities in the sewage, it can avoid foreign objects entering the pump body 2 during the pumping process and causing blockage, and has a good anti-blocking effect. During the pumping process, the spiral blade 11 of the guide tube 5 is impacted by the water flow and can drive the scraper 10 to rotate, and then scrape and clear the surface of the filter plate 7 to avoid blockage of the filter plate 7, thereby ensuring smoother pumping.

[0024] It is further worth explaining in detail that the connecting component 12 includes a limiting ring 13 fixed to one end of the water inlet pipe 3 shown, a mounting ring 14 is fixed to the outer wall of the guide pipe 5, and a plurality of elastic cards 15 distributed in a ring are fixed to one side wall of the mounting ring 14, and a limiting block 16 is fixed to one end of the elastic card 15, and the limiting block 16 and the limiting ring 13 are mutually engaged, and one end of the limiting block 16 is arranged at an angle; the end of the limiting block 16 is arranged at an angle to facilitate the splicing and installation of the guide pipe 5 and the water inlet pipe 3, and the guide pipe 5 and the water inlet pipe 3 are installed and fixed by the connecting component 12, which can facilitate the disassembly and assembly of the guide pipe 5, and then the internal filter plate 7 can be disassembled and cleaned to avoid the accumulation of a large number of impurities inside the guide pipe 5 and cause blockage.

[0025] It is further worth explaining in detail that a support seat 17 is fixed to the top of the base 1, a through groove 18 is opened on one side of the support seat 17, the guide tube 5 passes through the through groove 18, the outer wall of the guide tube 5 is slidably connected to the through groove 18, and the outer wall of the water inlet pipe 3 is fixed with two symmetrically arranged fixed blocks 19, and a sliding rod 20 is fixed between the two fixed blocks 19 and the support seat 17. Two symmetrically arranged sliding sleeves 21 are fixed to the outer wall of the guide tube 5, and the two sliding sleeves 21 are respectively slidably connected to the two sliding rods 20, and the outer wall of the sliding rod 20 is sleeved with a spring 22, and the two ends of the spring 22 are respectively fixed to the corresponding fixed blocks 19 and the sliding sleeves 21; the guide tube 5 is supported by the support seat 17, and the spring 22 is used to push the guide tube 5 to fit closely with the water inlet pipe 3, so as to ensure the stability of the guide tube 5.

[0026] This scheme has the following working process: when the sewage pump is in use, one end of the guide pipe 5 is connected to the sewage pipe through the flange 26 to pump sewage. When the pump body 2 is pumping water, the sewage is pumped into the water inlet pipe 3 through the guide pipe 5, and is discharged from the drain pipe after being sucked by the pump body 2. When the sewage enters the water inlet pipe 3 from the guide pipe 5, it is initially filtered through the filter plate 7 to prevent larger debris from entering the pump body 2 and causing blockage inside the pump body 2. At the same time, the sewage flow rate of the pump body 2 is fast during the pumping process. When the sewage hits the spiral blades 11, the spiral blades 11 rotate with the water flow, and then drive the rotating rod 9 to rotate. When the rotating rod 9 rotates, it drives the scraper 10 to rotate. When the scraper 10 rotates, it scrapes the surface of the filter plate 7, thereby preventing the surface of the filter plate 7 from being blocked when pumping water for a long time. After the pump body 2 completes the work, the guide pipe 5 can be disassembled and cleaned. When disassembling, After the filter 7 is removed, the filter plate 7 at the end of the filter 7 can be removed and the filter plate 7 can be removed to remove the filter plate 7. After the filter 7 is removed, the filter plate 7 can be removed and the filter plate 7 can be removed to remove the filter plate 7.

[0027] According to the above working process, it can be known that: by arranging the filter plate 7 inside the guide pipe 5 to isolate the larger impurities in the sewage, it can avoid the pump body 2 from being blocked by foreign objects entering the inside during the pumping process, and has a good anti-blocking effect. During the pumping process, the guide pipe 5 can drive the scraper 10 to rotate by the impact of the water flow, and then scrape and clear the surface of the filter plate 7 to avoid blockage of the filter plate 7, thereby ensuring smoother pumping.

[0028] It is further worth explaining that the filter plate 7 is disc-shaped, and a sealing ring 23 is fixed to the outer wall of the filter plate 7. The sealing ring 23 fits tightly with the annular groove 6. The annular groove 6 is encrypted with the sealing ring 23 to ensure the sealing between the water inlet pipe 3 and the guide pipe 5.

[0029] It is further worth explaining in detail that two guide rods 24 distributed vertically are fixed to the outer wall of the guide tube 5, and two grooves 25 distributed vertically are provided inside the through groove 18. The two guide rods 24 slide through the two grooves 25 respectively. The guide rods 24 can ensure that the guide tube 5 is relatively stable during disassembly and movement, and relatively accurate during installation and not easy to shift.

[0030] It is further worth explaining that a flange 26 is fixed to one end of the guide pipe 5 away from the water inlet pipe 3, and a plurality of symmetrically distributed universal wheels 27 are fixed to the bottom end of the base 1. The sewage pump is moved as a whole through the universal wheels 27, thereby improving the portability of the sewage pump.

[0031] In summary: the guide tube 5 and the water inlet pipe 3 are installed and fixed by the connecting assembly 12, which can facilitate the disassembly and assembly of the guide tube 5, and then the internal filter plate 7 can be disassembled and cleaned to avoid the accumulation of impurities inside the guide tube 5 and blockage. The guide tube 5 is supported by the support seat 17, and the spring 22 is used to push the guide tube 5 and the water inlet pipe 3 to fit tightly, which can ensure the stability of the guide tube 5. At the same time, the annular groove 6 cooperates with the sealing ring 23 to ensure the sealing between the water inlet pipe 3 and the guide tube 5.

[0032] The pump body 2 can be purchased on the market. The pump body 2 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
