Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to a novel sewage pump. Background Art

[0002] Sewage pump is a kind of centrifugal impurity pump, which has many forms: submersible and dry. The most commonly used submersible pump is QW submersible sewage pump, and the most common dry sewage pumps are W horizontal sewage pump and WL vertical sewage pump. It is mainly used to transport urban sewage, feces or liquid containing fibers. The medium of solid particles such as paper scraps is usually not more than 80℃. Because the medium being transported contains fibers that are easy to entangle or bunch. Therefore, the flow channel of this pump is easy to be blocked. Once the pump is blocked, the pump will not work normally, and even burn the motor, resulting in poor sewage discharge.

[0003] When the sewage pump currently used is pumping sewage, the solid matter in the water gathers back to the pumping end, which makes the pumping pipe easy to get stuck and the sewage pump is also easy to be damaged. Therefore, a new sewage pump is needed. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A novel sewage pump comprises a pumping module, wherein the pumping module comprises a casing, a pump body installed on the top of the casing, a U-shaped cavity opened inside the casing, two filter frames interference-fitted inside the U-shaped cavity, two vertical plates connected between the casing and the pump body, a box-shaped frame connected between the casing and the vertical plates, a filter plate adhered to the inner wall of the box-shaped frame, a shunt pipe connected between the pump body and the vertical plates, an electromagnetic valve installed on the shunt pipe, a hydraulic cylinder connected between the casing and the filter frame, and an opening opened outside the box-shaped frame, wherein the pumping end of the pump body is connected to the inside of the U-shaped cavity, and the filter plate is adhered to the top of the filter frame.

[0007] By adopting the above technical solution, the two filter frames are located inside the U-shaped cavity, and then the filter plate blocks the opening, and then the solenoid valve blocks the diversion pipe, so that the sewage can only enter the pump body. Then when the device is put into actual use, the box body is sunk to the bottom of the water, and then the pump body is started. After the sewage is screened by the box frame and the filter frame, the pure liquid comes to the bottom of the U-shaped cavity, which effectively reduces the probability of damage to the pump body.

[0008] In a preferred example, the utility model can be further configured as follows: the two vertical plates are vertically symmetrical about the pump body, and the outer sides of the vertical plates are vertically flush with the inner sides of the filter frame.

[0009] In a preferred example, the utility model can be further configured as follows: the width of the filter frame is equal to the distance between the vertical plate and the box-shaped frame, and the filter frame is movably plugged into the interior of the box-shaped frame.

[0010] In a preferred example, the utility model can be further configured as follows: the filter plate is fitted to the inner side of the opening, and two guide rods are installed on the top of the filter plate, and the two guide rods both slide through the top of the box-shaped frame.

[0011] In a preferred example, the utility model can be further configured as follows: two solenoid valves and two hydraulic cylinders are connected in series, and the solenoid valves are both electrically connected to a power source.

[0012] In a preferred example, the present invention can be further configured as follows: a plurality of legs are installed at the bottom of the box, and the plurality of legs are arranged in a matrix.

[0013] In a preferred example, the utility model can be further configured as follows: the aperture of the box-shaped frame is equal to the aperture of the filter plate, and the aperture of the filter frame is smaller than the aperture of the box-shaped frame.

[0014] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0015] 1. In the utility model, the two filter frames are located inside the U-shaped cavity, and then the filter plate blocks the opening, and then the solenoid valve blocks the diversion pipe, so that the sewage can only enter the pump body. Then when the device is put into actual use, the box body is sunk to the bottom of the water, and then the pump body is started. After the sewage is screened by the box frame and the filter frame, the pure liquid comes to the bottom of the U-shaped cavity, which effectively reduces the probability of damage to the pump body.

[0016] 2. In the utility model, after the filter frame and the box-type frame have been used in sewage for a period of time, they are connected to an external power supply, and then the movable end of the hydraulic cylinder is extended, the filter frame rises, the filter plate opens the opening, and then the filter frame is connected to the opening. During this period, the solenoid valve is opened, and then the pure liquid extracted by the pump body flows out from the diversion pipe, and the pure liquid impacts the filter frame and the box-type frame, so that the mesh holes on the two are opened, thereby ensuring the sewage extraction efficiency.
