Stirring sand sucking pump

Abstract

The invention discloses a stirring sand sucking pump. The stirring sand sucking pump comprises a sand sucking pump shell part and a stirrer, wherein the sand sucking pump shell part comprises a motor, a motor rotor shaft and a sand sucking pump shell; the motor is positioned in the sand sucking pump shell; in a sand sucking port at the lower end of the sand sucking pump shell, the motor rotor shaft is connected with the stirrer; the stirrer comprises a connecting shaft fixedly connected with the motor rotor shaft; the connecting shaft is connected with spiral blades, and is also connected with three layers of stirring discs; and the radiuses of the upper and lower layers of stirring discs are both larger than the radius of the middle layer of stirring discs. The stirring sand sucking pump realizes looseness of gravels in water through the spiral blades, and realizes stirring of the gravels through the stirring discs so as to conveniently absorb the gravels. The spiral blades are higher in cutting force or crushing force, and are provided with wear resisting layers for improving the wear resistance; preferentially, the stirring discs are produced by ceramic materials to achieve wear resistance; and convex teeth can be replaced when being badly worn.

Description

technical field [0001] The invention relates to the technical field of a sand suction pump, in particular to a stirring sand suction pump. Background technique [0002] The unique sealing device of the sand suction pump can effectively balance the pressure inside and outside the oil chamber, and protect the reliability of the mechanical seal to the greatest extent. running. The pre-stirring impeller of the sand suction pump can impact the deposited silt into high-concentration turbulent flow, so that the sand suction pump can achieve high-concentration silt suction without the need for additional devices, but when the adsorbed matter is too cohesive, it is prone to A phenomenon in which adsorption cannot be performed. In order to solve the above phenomenon that cannot be adsorbed, most of the current sand suction pumps are equipped with a high-pressure water pipeline or other forms to wash and stir the surrounding sediment, but this kind of structure has complex systems, u...

AI Technical Summary

Problems solved by technology

However, when the sand suction pump is working, the agitator is in contact with the sand almost all the time, so the agitator head will be severely worn. Once the wear is serious, the agitator head needs to be replaced, which will cause a huge waste of resources, so , a wear-resistant stirring sand suction pump is needed to solve the above problems
