Abstract

The invention belongs to the technical field of sewage pumps, and particularly relates to a self-unblocking sewage pump based on a flexible pump body. The self-unblocking sewage pump comprises a rubber cylinder body, a support ring, a rotating part, a spiral plate, a motor and a belt. According to the sewage pump, the motor is started to drive the rotating part to rotate, and the rotating part drives the spiral plate to rotate in the rubber cylinder body, so that the sewage pump achieves the function of pumping sewage; and the cylinder body of the sewage pump is made of rubber, when sundries block the space between the spiral plate and the rubber cylinder body, the spiral plate rotates to enable the sundries to extrude the rubber cylinder body, and the rubber cylinder body is elastically deformed, so that the space of the rubber cylinder body is expanded, the sundries are prevented from being stuck between the spiral plate and a rubber pipe body and are conveniently taken away by the spiral plate, the sewage pump realizes the function of automatically cleaning blocked sundries, the sewage pump is prevented from being stuck, the maintenance period of the sewage pump is prolonged, and the service life of the sewage pump is prolonged.

Description

technical field [0001] The invention belongs to the technical field of pumps, in particular to a self-clogging sewage pump based on a flexible pump body. Background technique [0002] Sewage pump is a kind of centrifugal impurity pump, which has many forms: such as submersible type and dry type. The most commonly used submersible type is QW type submersible sewage pump, and the most common dry type sewage pump is W type horizontal sewage pump. And WL type vertical sewage pump two kinds. It is mainly used to transport urban sewage, manure or liquid containing fiber. For the medium of solid particles such as paper scraps, the temperature of the conveyed medium is usually not higher than 80°C. Because the conveyed medium contains fibers that are easy to entangle or bunch. Therefore, the flow channel of this kind of pump is easy to be blocked. Once the pump is blocked, the pump will not work normally, and even the motor will be burned, resulting in poor sewage discharge. Bri...
