Description

Technical Field

[0001] The invention relates to the technical field of sludge pumps, in particular to an anti-clogging sludge pump. Background Art

[0002] A sludge pump is a pump specially designed to transport liquids containing solid particles. It usually has the characteristics of anti-clogging, corrosion resistance and high efficiency. It is suitable for various scenarios that need to handle solid-liquid mixtures, such as sewage treatment, industrial wastewater treatment, construction site drainage and agricultural irrigation.

[0003] The sludge pump in the prior art is generally composed of a pump body, an impeller, an inlet and outlet pipes and other structures. In order to prevent the sludge pump from being blocked during use, crushing blades and screens are generally installed at the impeller. When the impeller rotates, the sludge is guided into the pump body. At this time, the impeller can drive the crushing blades to rotate, so that the crushing blades can crush larger impurities in the sludge, and smaller sized sludge and impurities can be transported to the outlet through the screen, and larger sized sludge and impurities will continue to be crushed until they are smaller than the screen aperture and discharged.

[0004] However, in actual use, after the sludge pump is used, clean water is generally introduced to clean the inside of the pump body. If there is grease and grease-like substances inside the sludge attached to the inside of the pump body, it is not easy to clean it with clean water, so it will adhere to the screen, and then when used next time, these substances will gradually dry up. If it is inspected and cleaned before use, the pump body needs to be disassembled and installed, making the operation more complicated. If it is not inspected, the dried sludge will not only block the internal channel of the screen, increase the resistance to fluid flow, and cause the efficiency of the pump to decrease, but also cause friction and wear on the impeller, thereby reducing its performance and shortening its service life, thereby reducing the efficiency and economy of the use of the anti-clogging sludge pump.
