Anti-blocking submersible sewage pump

Abstract

The invention discloses an anti-blocking submersible sewage pump which comprises a fixed box. The middle of the inner side wall of the fixed box is fixedly connected with a motor, and the output end of the motor is fixedly connected with a rotary rod. A first sealing bearing is fixedly embedded into the middle of the left side face of the fixed box, and a blow-down box is arranged on the left sideof the fixed box. The left side face of the fixed box is fixedly connected with two symmetric fixed rods. According to the anti-blocking submersible sewage pump, the motor can operate to drive an impeller to rotate, and therefore sewage is rotated; the sewage is pumped out to be drained via a water outlet pipe through centrifugal force, the locking phenomenon is avoided during rotation, and the sewage can be filtered better through a screen mesh; and it is avoided that a large quantity of garbage and impurities enter a blow-down barrel to cause locking and damage of the impeller, and therefore the garbage left in a water inlet barrel is cleared away better, a fixed plate and the screen mesh are maintained and replaced more conveniently, and the anti-blocking capacity of the device is improved.

Description

technical field [0001] The invention relates to the technical field of sewage pumps, in particular to an anti-clogging submersible sewage pump. Background technique [0002] The sewage pump is a kind of pump product that is connected with the pump and the motor and submerges into the liquid to work at the same time. Compared with the general horizontal pump or vertical sewage pump, the sewage pump has a compact structure and a small footprint, and is easy to install and maintain. Large-scale sewage pumps are generally equipped with automatic coupling devices for automatic installation. Installation and maintenance are quite convenient, and the continuous operation time is long. Because the pump and motor are coaxial, the rotating parts of the sewage pump are light in weight, so the load on the bearings is relatively heavy. It is small, and its service life is much longer than that of ordinary pumps. When it is necessary to extract and discharge sewage, a sewage pump is often...
