Efficient and energy-saving sewage drainage equipment

Abstract

The invention discloses efficient and energy-saving sewage drainage equipment, and belongs to pollution discharge equipment. A water pumping shell and an electromagnetic coil are mounted in a buoyancy shell; the electromagnetic coil is fixed outside the water pumping shell; the lower end of the water pumping shell is fixed at the lower end in the buoyancy shell; a water outlet valve is fixed in a center hole of the water pumping shell; a push spring and an iron core piston are arranged in the water pumping shell; the push spring is pressed on the iron core piston; sealing plates respectively seal a water inlet cavity and a sewage inlet channel of an extruding cavity; a limiting plug is fixed in a plug hole in the iron core piston; a sealing ball or a sealing cone is mounted in an inner conical hole; and an accommodating hole is formed in the lower end of the iron core piston. The efficient and energy-saving sewage drainage equipment is compact in structure, low in vibration, high in utilization rate of electric energy, strong in power and suitable for pumping sewage in a sewage treatment station, a sewage pool and in a blocked sewage ditch; when sewage is pumped, the buoyancy shell floats on the sewage surface to automatically rise or descend along with change of the sewage surface, so that sediments and sludge cannot enter a sewage pump; and sewage can also flow automatically to be drained.

Description

technical field [0001] The invention relates to high-efficiency sewage discharge and energy-saving equipment in the field of sewage discharge. Background technique [0002] Traditionally, submersible pumps are used to discharge sewage in sewage pools and clogged sewage ditches, and blockage often occurs when sewage is discharged with submersible pumps. Therefore, we have designed a sewage pump that can float on the sewage surface. Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing and method of an efficient sewage discharge and energy-saving equipment that can float on the sewage surface to pump and discharge sewage. [0004] In order to achieve the above purpose, the high-efficiency sewage sewage and energy-saving equipment of the present invention mainly includes a buoyancy shell, an electromagnetic coil, a pump water shell, a water inlet hole, a sealing plate, a sealing ball or a sealing cone, a limiting cap, a propulsi...
