Anti-blocking sewage pump

Abstract

The invention discloses an anti-blocking sewage pump. The anti-blocking sewage pump comprises a sewage pump body and a support arranged on the side wall of the lower part of the sewage pump body and used for supporting, a water inlet is formed in the bottom of the sewage pump body, a sewage discharging pipe is arranged on the side wall of the sewage pump body, a water level sensor is arranged on the outer wall of the water inlet, and a water inlet pipeline is arranged on the side wall of the lower part of the water inlet. A filtering pipeline used for preventing garbage or granular impurities from entering is detachably arranged at the water inlet end of the water inlet pipeline, and the filtering pipeline comprises a connecting pipe and a filtering net pipe which are integrally arranged; a plurality of filtering net holes are evenly formed in the filtering net pipe, an internal thread is arranged on the inner wall of the connecting pipe, the connecting pipe is screwed on the water inlet pipeline through the internal thread, and a slope cutting surface which gradually inclines downwards from inside to outside is arranged at the end, far away from the connecting pipe, of the filtering net pipe; and a double-flow-channel cut-off type non-clogging impeller is arranged on the side, close to the water inlet, of the sewage pump body, and an auxiliary impeller is connected with the upper end of the double-flow-channel cut-off type non-clogging impeller.

Description

technical field [0001] The invention relates to the technical field of sewage pumps, in particular to an anti-blocking sewage pump. Background technique [0002] The sewage pump is a kind of pump product that is connected with the pump and the motor and submerged into the liquid at the same time. Compared with the general horizontal pump or vertical sewage pump, the sewage pump has a compact structure and is easy to install and maintain. Large sewage pumps are generally Equipped with an automatic coupling device for automatic installation, the installation and maintenance are quite convenient. Long continuous operation time. Because the pump and the motor are coaxial, the shaft is short, and the rotating parts are light, so the load (radial) on the bearing is relatively small, and the service life is much longer than that of ordinary pumps. There is no problem of cavitation damage and water diversion. Especially the latter point brings great convenience to the operator. ...

Problems solved by technology

With the continuous acceleration of the country's urbanization process, the rural population continues to transfer to the cities, the urban area and population continue to grow, and the amount of wastewater is also increasing; at the same time, people pay more attention to the environment, and the production sewage, domestic sewage and initial rainwater need to be discharged after centralized treatment , In some places where sewage is accumulated, it needs to be dredged. At this time, a sewage pump is needed for lifting and transporting; If it is not smooth, it will affect the normal operation of the sewage pump, cause damage to the motor, reduce the working efficiency of the sewage pump, and shorten the service life
