Description

Technical Field

[0001] The utility model relates to the technical field of submersible sewage pump cleaning, in particular to an automatic flushing device for a submersible sewage pump. Background Art

[0002] In modern sewage treatment and pumping station operations, submersible sewage pumps are one of the indispensable equipment. Submersible sewage pumps are usually used to discharge sewage, stir the dirt in storage tanks or ponds, and have the function of pumping sewage from a low place to a higher place. However, due to the solid particles and dirt in the sewage, submersible sewage pumps are susceptible to blockage and accumulation, resulting in performance degradation and failure. In order to solve these problems, automatic flushing devices were introduced into submersible sewage pumps. The automatic flushing device is a device attached to the submersible sewage pump, which is designed to regularly clean the suction port and pump body of the pump to keep the pump unobstructed and operating normally. It can effectively remove dirt and solid particles attached to the surface of the pump, prevent blockage and extend the life of the pump.

[0003] After searching, the existing patent (Announcement No.: CN217055726U) discloses an online self-flushing device for a submersible sewage pump, which relates to the technical field of submersible sewage pump cleaning devices, including: a flushing ring pipe, a plurality of flushing branches, a nozzle and a swirl guide plate, one end of the flushing branch pipe is connected to the flushing ring pipe, and the other end faces the liquid inlet of the submersible sewage pump, the nozzle is arranged on the end of the flushing branch pipe facing the liquid inlet, the flushing ring pipe is provided with a liquid inlet pipe fitting and a liquid outlet pipe fitting, the liquid inlet pipe fitting is fixedly connected to the liquid outlet of the submersible sewage pump, and the liquid outlet pipe fitting is provided with a liquid outlet valve for adjusting the liquid outlet amount. The utility model flushes the liquid inlet of the submersible sewage pump with the liquid outlet of the submersible sewage pump itself, flushes the liquid outlet of the submersible sewage pump online and in real time without wasting water resources, and avoids clogging by silt, thereby achieving the purpose of ensuring its long-term stable operation, not only without consuming water resources, but also saving time, effort and trouble.

[0004] However, in the actual use of the above scheme, water is sprayed out through the nozzle to clean the submersible sewage pump. However, due to the harsh use environment of the cleaning equipment, the nozzle is often blocked by impurities in the water, so the nozzle needs to be replaced frequently. The nozzle of the above device does not have the function of quick disassembly, which may cause the maintenance and cleaning process to take longer. This will extend the downtime of the submersible sewage pump and affect the continuity and efficiency of the sewage treatment process.

[0005] In view of this, the utility model provides an automatic flushing device for a submersible sewage pump. Utility Model Content
