Description

Technical Field

[0001] The utility model belongs to the field of sewage pumps, and in particular relates to an anti-clogging submersible sewage pump. Background Art

[0002] A sewage pump is a pump product in which the pump and the motor are connected and work underwater at the same time. Compared with general horizontal pumps or vertical sewage pumps, the sewage pump has a compact structure, small footprint, and is easy to install and maintain.

[0003] When the existing sewage pump discharges sewage, the garbage in the sewage is easy to settle at the bottom. If the sewage pump is continuously at the lower end of the sewage, the water inlet at the bottom is very easy to be blocked by the garbage at the bottom of the sewage, and the energy consumption of the sewage pump is increased, and the service life of the sewage pump is reduced. In addition, the garbage floating in the sewage is easy to adhere to and block the water inlet of the sewage pump, resulting in the sewage pump being unable to collect sewage better.

[0004] Therefore, in order to address the problem that when the above-mentioned sewage pump is used to discharge sewage, its water inlet is easily blocked by garbage floating in the sewage, and its bottom water inlet is easily blocked by garbage settled at the bottom of the sewage, an anti-blocking submersible sewage pump is developed. By adding multiple garbage filtering structures, electric crushing structures and four-corner stable floating structures to the sewage pump, the device's ability to handle garbage in sewage can be greatly improved, and the garbage settled in the sewage and the garbage floating on its surface can be prevented from clogging the sewage pump. Utility Model Content
