Description

Technical Field

[0001] The invention relates to the technical field of permanent magnetic iron removers, in particular to a suspended permanent magnetic iron remover. Background Art

[0002] Permanent magnetic iron remover is a device that uses the magnetic field generated by high-strength permanent magnetic materials (such as NdFeB, ferrite, etc.) to remove ferromagnetic impurities in materials. It can work continuously without external power. The permanent magnetic iron remover forms a strong magnetic field through permanent magnets. When the material passes directly under the permanent magnetic self-unloading iron remover, the ferromagnetic impurities mixed in the material are sucked up. Since the belt on the iron remover keeps running, when the ferromagnetic impurities adsorbed on it pass through the non-magnetic area, they are scraped out by the baffle on the belt and thrown into the iron collection box, thereby achieving the purpose of continuous and automatic iron removal.

[0003] The existing suspended permanent magnetic iron remover gradually exposed its shortcomings during use, mainly in the following aspects: First, the problem of ferromagnetic impurities swinging back and being sucked back. Specifically, the magnetic field strength of the permanent magnet is inversely proportional to the distance. In order to improve the adsorption effect of ferromagnetic impurities in the material, the lower end face of the permanent magnet is close to the conveyor belt. In order to prevent the material from being shifted, the height value of the baffle is small. When the flaky or slender ferromagnetic impurities move to the weak magnetic area, the magnetic force of the end entering the weak magnetic area decreases. When the gravity is greater than the magnetic force, this end begins to fall downward, and the entire ferromagnetic impurities rotate around one end in the strong magnetic area. When the gravity of the ferromagnetic impurities is large, they will break away from the belt and be thrown into the conveying equipment, causing the equipment to be stuck, seriously affecting the iron removal efficiency and equipment life. In addition, there is a certain probability that the ferromagnetic impurities will be thrown into the material on the conveyor belt, affecting the iron cleaning effect. When the gravity of the ferromagnetic impurities is small, the ferromagnetic impurities will flip over the baffle and be sucked to the belt surface just below the permanent magnet again. When there are many ferromagnetic impurities accumulated on the belt surface, a "magnetic bridge" is formed, which weakens the effective magnetic field strength. The ferromagnetic impurities in the material cannot be effectively adsorbed, resulting in poor iron cleaning effect.

[0004] Second, the gap and parallelism adjustment process between the permanent magnetic iron remover and the conveyor belt is complicated. Specifically, in order to ensure uniform distribution of the magnetic field and avoid ferromagnetic impurities from being absorbed by the edge, the permanent magnetic iron remover needs to be installed parallel to the conveyor belt. Most conveyor belts are inclined, and the four corners of the permanent magnetic iron remover are usually hung on the bracket with eyebolts and hooks. When adjusting the inclination angle of the permanent magnetic iron remover and the gap between the permanent magnetic iron remover and the conveyor belt, the four corners need to be adjusted one by one, and repeated measurements are required when the four corners are adjusted independently to ensure that the magnetic pole surface of the iron remover is parallel to the conveyor belt.

[0005] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

When adjusting the inclination angle of the permanent magnetic iron remover, a bolt tightening gun is used to drive the worm to rotate, and the driven shaft is driven to rotate under the transmission of the worm wheel. The two rotating shafts are driven to rotate synchronously under the transmission of the driving sprocket, the driving chain and the driven sprocket. When the rotating shaft and the lead screw produce relative rotation, one end of the support frame is driven to rise or fall, thereby adjusting the inclination angle of the permanent magnetic iron remover. When adjusting the height of the permanent magnetic iron remover, a bolt tightening gun is used to drive the two worms to rotate, so that the two ends of the support frame rise or fall to the same height, and then the height of the permanent magnetic iron remover is adjusted until the lower end face of the permanent magnet is close to the material on the conveyor belt.

When cleaning the iron on the material on the conveyor belt, the driving motor drives one of the rotating rollers to rotate, and then drives the unloading belt to rotate. When the unloading L-shaped plate moves in the arc section of the contraction guide plate, the blocking plate and the contraction guide plate are against each other. As the unloading belt rotates, the blocking plate slides toward the unloading L-shaped plate, and the compression spring is compressed until the unloading L-shaped plate enters the horizontal section of the contraction guide plate. The blocking plate is completely contracted, thereby preventing the material on the conveyor belt from being moved. When the material on the conveyor belt passes directly under the permanent magnet, the ferromagnetic impurities are sucked to the surface of the unloading belt directly under the permanent magnet, and the unloading L-shaped plate pushes the iron Magnetic impurities move. When the iron unloading L-shaped plate moves to one side of the material conveyor belt and has not moved out of the strong magnetic area of ​​the permanent magnet, the blocking plate separates from the contraction guide plate. With the cooperation of the compression spring, the blocking plate quickly resets, thereby lengthening the blocking length of ferromagnetic impurities. When the iron unloading L-shaped plate moves to the weak magnetic area, the iron unloading L-shaped plate and the blocking plate simultaneously block the ferromagnetic impurities to prevent the ferromagnetic impurities from swinging back or being sucked back. The suspended permanent magnetic iron remover can effectively solve the problem of swinging back and sucking back of ferromagnetic impurities without changing the gap between it and the material conveyor belt, thereby improving the iron cleaning effect of the material and protecting the material transportation equipment.

The lower support cylinder 22 is hinged to the support frame 3.

[0025] A driven shaft 28 rotatably arranged along a vertical line is provided inside the fixed housing 26, two driving sprockets 33 are fixedly mounted on the outer wall of the driven shaft 28, a driven sprocket 31 is fixedly mounted on the outer wall of the rotating shaft 23, the driving sprocket 33 is connected to the driven sprocket 31 via a driving chain 32, and the driven shaft 28 is rotationally connected to the fixed housing 26.

[0028] Both ends of the roller 11 and the rotating drum 5 are fixedly connected with a positioning shaft 9, and the top and bottom of the support frame 3 are fixedly installed with a plurality of bearing seats 10.

[0031] The bottom surface of the permanent magnet 4 is in frictional contact with the iron unloading belt 14 .

[0032] The working principle of this device is: When installing the equipment, the fixed frame 1 is fixedly connected to the material transportation equipment by welding or the like. When adjusting the inclination angle of the permanent magnetic iron remover, a bolt tightening gun is used to drive the worm 27 to rotate, and the driven shaft 28 is driven to rotate under the transmission of the worm wheel 29, and the two rotating shafts 23 are driven to rotate synchronously under the transmission of the driving sprocket 33, the driving chain 32 and the driven sprocket 31. When the rotating shaft 23 and the screw rod 25 produce relative rotation, one end of the support frame 3 is driven to rise or fall, thereby adjusting the inclination angle of the permanent magnetic iron remover. When adjusting the height of the permanent magnetic iron remover, a bolt tightening gun is used to drive the two worms 27 to rotate, so that the two ends of the support frame 3 rise or fall to the same height, and then the height of the permanent magnetic iron remover is adjusted until the lower end surface of the permanent magnet 4 is close to the material on the conveyor belt. When adjusting the inclination angle and the distance between the permanent magnetic iron remover and the conveyor belt, the four corners can be adjusted by adjusting the two corners synchronously, which greatly reduces the adjustment operation and measurement operation, and simplifies the distance adjustment process and parallelism adjustment process between the permanent magnetic iron remover and the conveyor belt. When cleaning the iron from the material on the conveyor belt, the driving motor 8 drives one of the rotating rollers 5 to rotate, thereby driving the unloading belt 14 to rotate. When the unloading L-shaped plate 13 moves in the arc section of the shrinking guide plate 15, the blocking plate 12 abuts against the shrinking guide plate 15. As the unloading belt 14 rotates, the blocking plate 12 slides toward the unloading L-shaped plate 13, and the compression spring 19 is compressed until the unloading L-shaped plate 13 enters the horizontal section of the shrinking guide plate 15. The blocking plate 12 is completely contracted, thereby preventing the material on the conveyor belt from being moved. When the material on the conveyor belt passes directly under the permanent magnet 4, the ferromagnetic impurities are sucked to the surface of the unloading belt 14 directly under the permanent magnet 4, and the unloading L-shaped plate 13 is moved. Plate 13 pushes ferromagnetic impurities to move. When the iron unloading L-shaped plate 13 moves to one side of the material conveyor belt and has not moved out of the strong magnetic area of ​​the permanent magnet 4, the blocking plate 12 is separated from the contraction guide plate 15. With the cooperation of the compression spring 19, the blocking plate 12 is quickly reset, thereby lengthening the blocking length of the ferromagnetic impurities. When the iron unloading L-shaped plate 13 moves to the weak magnetic area, the iron unloading L-shaped plate 13 and the blocking plate 12 simultaneously block the ferromagnetic impurities to prevent the ferromagnetic impurities from swinging back or being sucked back. The suspended permanent magnetic iron remover can effectively solve the problem of swinging back and sucking back of ferromagnetic impurities without changing the gap between it and the material conveyor belt, thereby improving the iron cleaning effect of the material and protecting the material transportation equipment.
