[0002] A centrifugal pump works by using the rotation of the impeller to cause water to move centrifugally. Before starting the pump, the pump casing and the suction pipe must be filled with water. Then the motor is started so that the pump shaft drives the impeller and water to rotate at high speed. The water moves centrifugally and is thrown to the outer edge of the impeller. It flows into the water pressure pipeline of the water pump through the flow channel of the volute pump casing. When the centrifugal pump is used in daily life, it needs to be connected to the centrifugal pump through a connecting pipe.

[0003] However, when the centrifugal pump connecting pipe is used, it is often directly connected to the centrifugal pump. The magnetic adsorption effect on the iron chips in the connecting pipe is not high, and the all-round cleaning and collection effect after the iron chips are adsorbed is not high, so that the iron chips in the connecting pipe will enter the centrifugal pump, causing damage to the centrifugal pump and increasing the cost of using the centrifugal pump.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a device for removing iron chips by magnetic attraction is proposed. Utility Model Content

The inner wall of the fixed scraper 14 is fixedly connected to the second electric push rod 15, and one end of the second electric push rod 15 is fixedly connected to a telescopic scraper 16.

[0024] Furthermore, two groups of storage boxes 4 and connecting boxes 3 are provided, and the position distribution of the two groups of storage boxes 4 and connecting boxes 3 is symmetrical about the central axis of the magnetic block 12. This is beneficial for achieving the effect of convenient cleaning and collection of iron filings on both sides of the magnetic block 12 by setting two groups of storage boxes 4 and connecting boxes 3 whose position distribution is symmetrical about the central axis of the magnetic block 12.

[0025] Furthermore, the rotating shaft 10 forms a rotating structure with the fixed box 6 through the worm 8 and the worm wheel 9. The rotation center of the worm wheel 9 and the rotation center of the rotating shaft 10 are arranged to coincide with each other, which is beneficial to the rotation of the worm 8. Through the connection of the worm wheel 9, the rotating shaft 10 is driven to rotate along the inner wall of the fixed box 6, thereby driving the magnetic block 12 to conveniently flip.
