Axial-flow pump with filtering and cleaning functions

Abstract

The invention discloses an axial-flow pump with filtering and cleaning functions, and belongs to the technical field of axial-flow pumps. The axial-flow pump comprises a pump body. A water inlet partis arranged at the lower end of the pump body. A water outlet bent pipe is arranged at the upper end of the pump body. A pump shaft is arranged in the pump body. A guide impeller and an impeller are sequentially arranged at the lower end of the pump shaft from top to bottom. A filter component is arranged at the lower end of the pump body and is located below the guide impeller and the impeller. Acleaning device is arranged below the filter component and comprises a rotary shaft. The upper end of the rotary shaft is fixedly connected with the filter component. Rotary blades are arranged at the lower end of the rotary shaft. A rotary sleeve which can vertically move up and down along the rotary shaft is positioned on the outer circumference of the rotary shaft in the circumferential direction, and a guide rod perpendicular to the rotary shaft is fixed to the rotary sleeve. Two spiral grooves having opposite spiral directions are formed in the portion, located on the rotary shaft, of the inner wall of the pump body, and the two spiral grooves intersect and communicate with each other. The guide rod is provided with sliding blocks slidably inserted into the spiral grooves. A cleaningdisc is rotatably mounted on the periphery of the guide rod and is close to the inner wall of the pump body. The axial-flow pump with the filtering and cleaning functions has the advantage that blockage caused by impurities adhering to the inner wall of the pump is avoided.

Description

technical field [0001] The invention relates to the technical field of axial flow pumps, in particular to an axial flow pump with filtering and cleaning functions. Background technique [0002] The axial flow pump relies on the force generated by the blades of the rotating impeller on the liquid to transport the liquid along the axial direction. The axial flow pump impeller is equipped with 2 to 7 blades and rotates in a circular tubular pump casing. The pump casing above the impeller is equipped with a vane wheel to eliminate the rotational motion of the liquid and change it into axial motion, and convert the kinetic energy of the rotational motion into pressure energy. The axial flow pump is generally vertical, and the impeller is submerged under the water. After long-term use, impurities in the water are easy to stick to the wall and block the axial flow pump, which affects the use of the axial flow pump.
