Description

Technical Field

[0001] The utility model relates to the technical field of water pump filtration, in particular to a water pump for filtering sediment. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. For example, it can be used to transport water, oil, acid and alkali liquids, liquid metals, etc. It can also be used to transport liquids, gas mixtures, and liquids containing suspended solids. It transfers the original mechanical energy or external energy to the liquid, allowing the liquid energy to increase rapidly.

[0003] A Chinese patent with publication number CN216477817U was searched and found to have a water pump for efficiently filtering sediment.

[0004] The above technical scheme includes: a water pump, the bottom surface of the water pump is fixedly connected to a shell, the bottom surface of the shell is provided with a plurality of filter holes, a reciprocating screw is rotatably connected in the shell, one end of the reciprocating screw is fixedly connected to the driving shaft of the water pump, a push plate is threadedly connected to the reciprocating screw, and a limit rod fixedly connected to the bottom surface of the shell is slidably connected on the push plate. This novel water pump with high efficiency in filtering sediment is provided with two symmetrical filter assemblies on the shell by setting a push plate with existing threads on the reciprocating screw, so that the reciprocating screw is driven to rotate by the driving shaft of the water pump, the push plate moves up and down, the filter holes on the water flow shell enter the shell, and enter the top of the push plate from the return pipe. The water flows through the filter plate in the filter assembly through the squeezing of the push plate and is discharged from the water pump, so that the water flow is subjected to multiple filtrations with high filtration efficiency, and is convenient to use.

[0005] However, in the above scheme, when filtering impurities such as aquatic plants and leaves, the aquatic plants and leaves will cover the outside of the filter hole, and the push pin will push the aquatic plants to open the hole. Due to the suction of the water pump, the aquatic plants will continue to cover the filter hole, causing water inlet blockage. When the push pin passes through the filter hole, the push plate moves toward the filter hole, and the push plate will completely cover the filter hole. Water cannot enter, causing internal vacuum. At the moment the push plate leaves, the huge pressure difference will break the coarse impurities into fine impurities, and under the push of the push plate, they quickly gather on the filter plate, causing the filter plate to be blocked.

[0006] For this purpose, we propose a water pump for filtering sediment. Utility Model Content
