Description

A magnetic sorting device for solid sand processing Technical Field

[0001] This invention relates to the field of magnetic separation device technology, specifically a magnetic separation device for solid sand processing. Background Technology

[0002] In the production process of sand, in order to improve the purity of sand, it is necessary to remove magnetic mineral sand from the sand. Electromagnetic separators are usually used to adsorb and remove magnetic mineral sand from the sand. The electromagnetic separator consists of an outer rotating drum, an inner magnetic core, a feed inlet, and a discharge outlet. By rotating the feed roller located at the feed inlet, the sand is pushed onto the surface of the outer rotating drum. The inner magnetic core inside the outer rotating drum magnetically attracts the magnetic mineral sand in the sand. The magnetic force causes the magnetic mineral sand to adhere to the outer wall of the outer rotating drum. Under the brushing action of the discharge brush on the other side, the magnetic mineral sand is removed from the surface of the outer rotating drum and discharged, thus completing the removal of impurities.

[0003] In the prior art, patent document CN115591667A discloses a high-purity sand removal electromagnetic separator. The invention causes the crushed sand to adhere to the outside of the outer rotating drum due to its own gravity, and then the magnetic mineral impurities are adsorbed by the inner magnetic core through the outside of the outer rotating drum. This part of the crushed sand flows out through the opening of the elastic sheet, improving the purity of the sand. However, the above-mentioned magnetic separation device is not convenient for dynamic agitation magnetic separation of sand during magnetic separation, so the magnetic separation efficiency is difficult to improve effectively. Moreover, the existing magnetic separation device is not convenient for rapid air purification of residual impurities inside the device.

[0013] The beneficial effects of this invention are:

[0014] 1. In the magnetic separation process of this invention, current is applied to the arc rail, the motor outputs a set speed, and the air purification pump is normally turned on. After the motor outputs the speed, the reciprocating guide component drives the outer shaft cylinder and the transmission shaft to perform a set stroke of left-right reciprocating motion within the magnetic separation chamber. After the outer shaft cylinder and the transmission shaft reciprocate left and right, they then drive the magnetic separator rod to move left and right simultaneously during its rotation and revolution. This achieves reciprocating magnetic separation of magnetic materials in the solid sand, thereby effectively improving the magnetic separation efficiency and accuracy. The magnetic material in the drum is magnetically adsorbed by the magnetic separation plate and magnetic separation rod. As the drum rotates, the solid sand without magnetic material is directly discharged through the feed pipe. When the magnetic separation rod or magnetic separation plate moves to the position of the notch, the magnetic separation rod or magnetic separation plate that moves to the notch loses its magnetic force. The magnetic material separated by the magnetic separation rod and magnetic separation plate is discharged through the magnetic tube. When the magnetic separation module moves to the position of communicating with the cavity, the air jet channel releases high pressure air. After the air jet channel releases high pressure air, it then blows away the solid sand, impurities and dirt remaining on the surface of the magnetic separation chamber and magnetic separation plate under high pressure.

[0015] 2. During operation, the two sets of vibrators synchronously output vibration frequencies. Through the vibration frequency output of the vibrators, the magnetic separator can reciprocate up and down. The reciprocating up and down vibration of the magnetic separator can effectively shake off the solid sand adhering to the inside of the magnetic separation chamber or the magnetic material remaining on the non-magnetic magnetic separator rod. On the other hand, it can fully disperse the solid sand to be magnetically separated. By achieving the effect of fully dispersing the solid sand, the separation rate between the solid sand and the magnetic material is effectively improved, and the particle separation effect of the solid sand and the magnetic material is improved. Through the improvement of the particle separation effect of the sand or magnetic material, the magnetic separation efficiency and magnetic separation accuracy of this magnetic separation device are effectively improved.

[0056] The working principle of this invention is as follows: This invention is mainly applicable to magnetic separation of residual magnetic materials in solid sand. During magnetic separation, current is passed through the arc rail 10, the motor 5 outputs a speed in a set state, and the air purification pump 33 is normally turned on. After the motor 5 outputs its speed, the reciprocating guide component drives the outer shaft cylinder 24 and the transmission shaft 27 to perform a set stroke of left and right reciprocating motion within the magnetic separation chamber 7. After the outer shaft cylinder 24 and the transmission shaft 27 perform left and right reciprocating motion, they then drive the magnetic separator 26 to perform synchronous rotation and revolution. During the process, left and right displacement can occur, thereby realizing reciprocating magnetic separation of magnetic materials in solid sand. Through reciprocating magnetic separation, the magnetic separation efficiency and accuracy are effectively improved. Magnetic materials in the sand are magnetically attracted by the magnetic separation plate 8 and magnetic separation rod 26. As the rotating drum 6 rotates, solid sand without magnetic materials is directly discharged through the feed pipe 3. When the magnetic separation rod 26 or magnetic separation plate 8 moves to the position of the notch, the magnetic separation rod 26 or magnetic separation plate 8 that has moved to the notch loses its magnetic force. The magnetic material separated by plate 8 is discharged through magnetic tube 4. When the magnetic separation module moves to the position connected to cavity 25, high-pressure air is emitted from air jet channel 35. After high-pressure air is emitted from air jet channel 35, solid sand, impurities, and dirt remaining on the surface of magnetic separation chamber 7 and magnetic separation plate 8 are blown away by high pressure. At the same time, during magnetic separation, two sets of vibrators 15 synchronously output vibration frequency. Through the vibration frequency output of vibrators 15, the magnetic separation cylinder 1 can reciprocate in the up and down direction. The reciprocating vibration effectively shakes off solid sand adhering to the magnetic separation chamber 7 or magnetic material remaining on the non-magnetic magnetic separator 26. It also fully disperses the solid sand to be magnetically separated. By achieving full dispersion of the solid sand, the separation rate between the solid sand and the magnetic material is effectively improved, and the particle separation effect of the solid sand and the magnetic material is enhanced. Through the improvement of the particle separation effect of the sand or magnetic material, the magnetic separation efficiency and magnetic separation accuracy of this magnetic separation device are effectively improved.
