Embodiment 1

[0021] like figure 1 and 2 As shown, Embodiment 1 provides a double-stirring double-cutting sewage pump, which includes a motor 1, a pump body 2, an impeller 3, a connecting pipe 4, a first stirring and cutting part and a second stirring and cutting part, and the pump body 2 is cylindrical Hollow shell, the right end of the pump body 2 is provided with a water inlet (not shown in the drawings), the side of the cylinder of the pump body 2 is provided with a water outlet (not shown in the drawings), and the motor 1 is fixed on the left end of the pump body 2 The motor 1 provides the kinetic energy for the sewage pump to do work. The motor shaft 5 of the motor 1 runs through the pump body 2 and the free end of the motor shaft 5 is exposed at the water inlet of the pump body 2. The exposed part of the motor shaft 5 is used to install other parts. The impeller 3 Set in the pump body 2, and the impeller 3 is socketed and fixed on the motor shaft 5. The impeller 3 and the motor shaf...

Embodiment 2

[0024] Embodiment 2 provides a double-agitation and double-cutting sewage pump, whose structure is basically the same as that of the double-agitation and double-cutting sewage pump provided in embodiment 1, and only the differences will be described below.

[0025] In this embodiment, the first movable knife 6 is a circular plate, and when the circular plate-shaped first movable knife 6 is working in the sewage pump, its circular plane can also prevent sundries in the sewage from directly entering the water inlet. , to avoid sundries hitting the impeller 3, the arc edge of the circular plate is the cutting edge of the first moving knife, the axis of the first moving knife 6 coincides with the axis of the motor shaft 5, and there are two first moving knives 6, both of which are set On the right side of the motor shaft 5 and the two are arranged at intervals along the axial direction of the motor shaft 5, a shaft sleeve 13 is arranged between the two first moving knives 6, and th...

Abstract

The invention discloses a double-stirring double-cutting sewage pump. The double-stirring double-cutting sewage pump comprises a pump body, a motor, an impeller, a connecting pipe, a first stirring and cutting part and a second stirring and cutting part, wherein the motor is fixed on the left end surface of the pump body, a motor shaft of the motor runs through the pump body and is exposed from awater inlet of the pump body, the impeller is arranged in the pump body and is sheathed and fixed on the motor shaft, the first stirring and cutting part is arranged on the right end surface of the pump body, the first stirring and cutting part comprises a first movable knife and a first static knife, the first movable knife and the first static knife cooperate to cut sundries, the second stirringand cutting part is arranged at the water inlet and comprises a second movable knife and a second static knife, and the second movable knife and the second static knife cooperate to cut the sundries.The double-stirring double-cutting sewage pump provided by the invention has the advantages that by two-stage cutting, the sundries in sewage can be cut and crushed, a sewage pump is prevented from being blocked, and two stages of movable knifes are driven by the motor to stir sediments at the bottom of a pool, so that pollution discharge capability is strong.

Description

technical field [0001] The invention relates to the technical field of sewage pumps, in particular to a double-stirring and double-cutting sewage pump. Background technique [0002] The sewage pump is the pump that drains the sewage. It is installed at the bottom of the sewage tank. It is easy to install and maintain, and has a long continuous operation time and high reliability. It is widely used. The sewage pump mainly transports the following: ①domestic sewage with discarded shopping bags, sanitary napkins, and broken socks; Fish pond silt with pebbles; ④Urban sewage with fine wire, foam blocks, branches and leaves. Because the transported sewage contains easily entangled substances or substances that are easy to deposit and agglomerate, and are not easy to be sucked by the sewage pump, it is not easy for the traditional sewage pump to discharge such sewage, and the entangled substances are easy to cause the sewage pump to block. Once the sewage pump is blocked, it will...
