Description

TECHNICAL FIELD

[0001] The utility model relates to the field of impurity filtering, and particularly relates to a ferromagnetic impurity filtering device. BACKGROUND

[0002] Because the oil liquid used by the oil pump experiment table often contains metal impurities caused by various reasons, in order to ensure the cleanliness of the oil liquid and avoid damage caused by impurities during product test running, a metal impurity filtering device in the oil liquid needs to be designed.

[0003] CN219210261U discloses an oil filter assembly, which comprises a main body, an oil inlet pipe communicated with one side of the surface of the main body, an oil outlet pipe communicated with the other side of the surface of the main body, a filter core fixedly connected to the inner side of the main body, a fixing ring on the surface of the filter core, buffer springs on the surface of the fixing ring, mounting rings at one end of the buffer springs away from the fixing ring, and magnetic rings on the side of the mounting rings away from the buffer springs. The device is provided with a mounting mechanism and a fixing nut, which can fix the magnetic rings on one side of the mounting rings, thereby adsorbing the magnetic impurities in the oil liquid, avoiding the failure of the filter holes to filter the magnetic impurities, making the magnetic impurities follow the oil liquid to be discharged from the inside of the main body, improving the filtering effect of the filter assembly, and fully filtering the oil liquid. The buffer springs are contracted under stress to buffer the impact force applied to the magnetic rings when the oil liquid passes through the magnetic rings. The device installs the magnetic rings in the filter core to adsorb the magnetic impurities in the oil liquid, but the adsorption of the ferromagnetic impurities in the oil liquid is not complete. Therefore, there is an urgent need to design a filtering device with a simple structure and complete adsorption of ferromagnetic impurities. SUMMARY

[0004] The utility model aims at providing a ferromagnetic impurity filtering device to solve the problem of filtering ferromagnetic impurities in oil liquid.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A ferromagnetic impurity filtering device comprises a slag collecting box and a rack connected with the slag collecting box. A permanent magnet for adsorbing ferromagnetic impurities is arranged in the slag collecting box. An electromagnet with a shape matching that of the rack is fixedly connected to the inside of the rack. A magnetic conducting wire is fixed on the electromagnet, and the magnetic conducting wire forms a mesh structure in the inside of the electromagnet. The magnetic conducting wire and the electromagnet are arranged in the inside of the rack and above the slag collecting box. A switch for controlling the power-on and power-off of the electromagnet is arranged on the rack. When the switch is turned on, the electromagnet is magnetized, and the magnetic conducting wire also has magnetism.

[0007] Further, the slag collecting box has a cubic cavity structure.

[0008] Furthermore, the upper half of the frame is an annular structure, and the lower half of the frame is placed in the slag collecting box and is threadedly connected to the slag collecting box.

[0009] Furthermore, the electromagnets are arranged along the internal annular structure of the frame to form an open circular ring structure.

[0010] Furthermore, the permanent magnet is arranged at the bottom of the slag collecting box and can be taken out from the slag collecting box.

[0011] The beneficial effects of the utility model are as follows: the utility model provides a magnet and a fixedly installed magnetic wire in the frame, utilizes the magnetic property of the magnet after being energized, controls the switch to make the magnetic wire also magnetic, and the ferromagnetic impurities in the oil will be absorbed through the mesh structure formed by the magnetic wire. After the power is cut off, the absorbed ferromagnetic impurities will fall into the slag collecting box and be captured by the permanent magnet in the slag collecting box.

[0016] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0017] The utility model Figure 1 and Figure 2As shown, the device is installed in the oil pipe between the oil pools; the device includes a magnetic wire 1, an electromagnet 2, a frame 3, a switch 4, a slag collecting box 5, and a permanent magnet 6. The slag collecting box 5 is a cubic cavity structure, and one side of the top of the slag collecting box 5 is in an unclosed state. A permanent magnet 6 is provided at the bottom of the slag collecting box 5, and the permanent magnet 6 can be taken out of the slag collecting box 5.

[0018] The upper part of the frame 3 is annular and has a passage for the filtered oil to pass through. The lower part of the frame 3 is located on the unsealed side of the upper part of the slag collecting box 5 and is threadedly connected to this part of the slag collecting box 5.

[0019] An electromagnet 2 is fixedly mounted on the inner middle portion of the frame 3 . The electromagnet 2 is arranged along the inner annular contour of the frame 3 and is adapted to the frame 3 . The electromagnet 2 is in an open circular ring structure.

[0020] The electromagnet 2 is provided with a magnetic wire 1 wound around the electromagnet 2. The magnetic wire 1 is directly fixed on the electromagnet 2 to form a mesh structure. The entire mesh structure formed by the electromagnet 2 and the magnetic wire 1 is placed inside the ring of the frame 3 and is located above the slag collecting box 5.

[0021] A switch 4 is provided on the outside of the frame 3 near the slag collecting box 5 , and the switch 4 controls the power on and off of the electromagnet 2 .

[0022] The working principle of the utility model is: (1) turning on the switch 4 so that the electromagnet 2 is energized, and the magnetic wire 1 becomes magnetic when the electromagnet 2 is energized;

[0023] (2) The liquid to be filtered is passed through the frame 3 and through the mesh structure formed by the magnetic wire 1. At this time, the ferromagnetic impurities in the liquid will be attracted by the magnetic wire 1.
