Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic pumps, and in particular relates to a magnetic pump provided with a filter screen. Background Art

[0002] The magnetic pump is a new type of seal-less pump that uses the principle of permanent magnetic transmission technology to achieve contactless transmission of torque. A filter is generally installed inside the magnetic pump to filter the water entering the magnetic pump, thereby filtering out impurities and harder particles in the water to prevent them from entering the pump body.

[0003] Currently, most magnetic pumps install a filter at the end of the liquid inlet pipe of the pump body to filter impurities and relatively hard particle debris in the water. However, the filtered impurities and relatively hard particle debris will adhere to the surface of the filter. Long-term accumulation can easily cause the filter to be blocked. After the blockage, the magnetic pump needs to be shut down and the filter at the end of the liquid inlet pipe needs to be disassembled and cleaned. This cleaning method not only requires the filter to be disassembled and cleaned, but also easily delays the operation of the magnetic pump, which is more troublesome and affects the normal use of the magnetic pump.

[0027] A sewage pipe 14 is provided on the surface of the water pipe 3 and at the bottom of the brush 7, and a sealing cover 15 is threadedly connected to the bottom of the sewage pipe 14. A filter box 16 is snapped into the sewage pipe 14.

[0028] A control valve 17 is provided on the surface of the water pipe 3 , and the control valve 17 is used to control the opening and closing of the channel in the water pipe 3 .

[0029] One end of the water inlet bin 4 is connected to a water inlet pipe 18, through which the water inlet pipe 18 can be connected to a pipeline outside that needs to deliver water.

[0030] The magnetic pump provided with a filter screen connects the water inlet pipe 18 at one end of the magnetic pump 2 with the external pipe that needs to deliver water, so that the water in the water pipe enters the water inlet bin 4 through the water inlet pipe 18, and enters the magnetic pump 2 through the two groups of water delivery pipes 3 connected to the water inlet bin 4, and the water entering the water delivery pipes 3 can be filtered through the filter screen 5, and when the filter screen 5 in one group of water delivery pipes 3 is blocked, the blocked water delivery pipe 3 can be closed by the control valve 17 to stop water delivery, while the other group of water delivery pipes 3 can deliver water normally, ensuring that the magnetic pump 2 can work without stopping;
