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:

[0004] 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.

[0005] 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.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0007] In view of the defects in the prior art, the technical problem to be solved by the present invention is to provide a suspended permanent magnet iron remover, which can effectively solve the problems of backswing and back suction of ferromagnetic impurities without changing the gap between it and the conveyor belt, improve the iron removal effect on materials, and protect the material transportation equipment.

[0008] When adjusting the tilt angle and the distance between the suspended permanent magnet iron remover and the conveyor belt, the four corners can be adjusted by the method of synchronous adjustment of two corners, which greatly reduces the adjustment operation and measurement operation, and simplifies the distance adjustment process and parallelism adjustment process between the permanent magnet iron remover and the conveyor belt.

[0009] To solve the above problems, the present invention provides the following technical solutions:

[0010] A suspended permanent magnet iron remover includes two fixed frames. A support frame is arranged between the two fixed frames. The support frame is hinged to the two fixed frames through two adjusting components. A permanent magnet is fixedly installed on the inner wall of the support frame. Two rollers and a rotating drum are respectively arranged above and below the support frame and are rotatably arranged along the horizontal line. The two rollers are connected to the two rotating drums through a scrap iron belt. The permanent magnet is located inside the scrap iron belt. A number of detachably arranged scrap iron L-shaped plates are evenly distributed on the outer surface of the scrap iron belt. A vertically slidable partition plate is arranged at the end of the scrap iron L-shaped plate. The opposite inner walls of the support frame are fixedly connected with contraction guide plates. The contraction guide plates are divided into an arc section and a horizontal section. The distance between the arc section of the contraction guide plate and the scrap iron belt gradually decreases along the movement track of the scrap iron belt. The horizontal section of the contraction guide plate is parallel to the scrap iron belt and the distance is the same as the minimum distance between the arc section of the contraction guide plate and the scrap iron belt. The horizontal section of the contraction guide plate horizontally extends into the strong magnetic region of the permanent magnet. When the scrap iron L-shaped plate moves between the contraction guide plate and the scrap iron belt, the partition plate is in frictional contact with the contraction guide plate.

[0011] As an optimized scheme, a number of fixedly arranged fixed cylinders are evenly distributed at the bottom of the scrap iron L-shaped plate. A number of top plates are fixedly connected to the end of the partition plate. A sliding rod is arranged inside the fixed cylinder. The top end of the sliding rod passes upward through the fixed cylinder and is fixedly connected to the top plate. The sliding rod is slidably connected to the fixed cylinder. A compression spring is sleeved on the outer wall of the fixed cylinder. The two ends of the compression spring are respectively abutted against the scrap iron L-shaped plate and the top plate.

[0012] As an optimized solution, the adjusting component includes a fixed box body. At the top and bottom of the fixed box body, there are respectively two fixedly arranged upper support cylinders and lower support cylinders. Inside the fixed box body, there are two rotating shafts rotatably arranged along the vertical line, and the two rotating shafts are synchronously rotated. At the inner top of the upper support cylinder and the inner bottom of the lower support cylinder, there are thrust bearings. The two ends of the rotating shaft pass through the fixed box body and enter the upper support cylinder and the lower support cylinder respectively and abut against the thrust bearings. The upper support cylinder and the lower support cylinder are both rotationally connected to the rotating shaft. The top of the upper support cylinder is provided with an avoidance hole through which a connecting column is hinged to the inner top of the fixed frame. At the bottom of the connecting column, a lead screw is fixedly provided. The bottom end of the lead screw extends downward through the avoidance hole into the rotating shaft and is threadedly connected to the rotating shaft. The lower support cylinder is hinged to the support frame.

[0013] As an optimized solution, inside the fixed box body, there is a driven shaft rotatably arranged along the vertical line. On the outer wall of the driven shaft, two driving sprockets are fixedly sleeved. On the outer wall of the rotating shaft, a driven sprocket is fixedly sleeved. The driving sprocket is connected to the driven sprocket through a driving chain. The driven shaft is rotationally connected to the fixed box body.

[0014] As an optimized solution, on the outer wall of the driven shaft, a worm gear is fixedly sleeved. Inside the inner wall of the fixed box body, a worm is rotatably provided and meshes with the worm gear. One end of the worm passes through the fixed box body and extends to the outside and is in a hexagonal prism structure.

[0015] As an optimized solution, on the surface of the iron-removing belt, there are a number of bolt mounting holes penetrating through. The iron-removing L-shaped plate is connected to the iron-removing belt through bolts and nuts.

[0016] As an optimized solution, at both ends of the idler roller and the rotating drum, there are fixedly connected positioning shafts. At the top and bottom of the support frame, a number of bearing seats are fixedly installed. One end of the positioning shaft extends into the bearing seat and is rotationally connected to the bearing seat.

[0017] As an optimized solution, at the bottom of the support frame, a driving motor is fixedly installed. On the output shaft of the driving motor and the outer wall of one of the positioning shafts, there are fixedly sleeved transmission sprockets. The two transmission sprockets are connected through a transmission chain.

[0018] As an optimized solution, the contraction guide plate is fixedly connected to the support frame through a number of connecting plates.

[0019] As an optimized solution, the bottom surface of the permanent magnet is in frictional contact with the iron-removing belt.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. When installing the device, fixedly connect the fixing frame and the material transportation device by welding or other means. When adjusting the inclination angle of the permanent magnet iron remover, use a bolt tightening gun to drive the worm to rotate. Driven by the worm gear, the driven shaft rotates. Driven by the driving sprocket, driving chain and driven sprocket, the two rotating shafts rotate synchronously. When the rotating shaft and the lead screw rotate relative to each other, one end of the support frame rises or falls, thereby adjusting the inclination angle of the permanent magnet iron remover. When adjusting the height of the permanent magnet iron remover, use a bolt tightening gun to drive two worms to rotate, so that both ends of the support frame rise or fall by the same height, and then adjust the height of the permanent magnet iron remover until the lower end face of the permanent magnet is close to the material on the conveyor belt. When adjusting the inclination angle and the distance between the permanent magnet iron remover and the conveyor belt, the four corners can be adjusted by the method of synchronous adjustment of two corners, greatly reducing the adjustment operation and measurement operation, and simplifying the distance adjustment process and parallelism adjustment process between the permanent magnet iron remover and the conveyor belt;

[0022] 2. When cleaning the iron from the material on the conveyor belt, the driving motor drives one of the rotating drums to rotate, and then drives the iron unloading belt to rotate. When the iron unloading L-shaped plate moves within the arc section of the contraction guide plate, the baffle plate abuts against the contraction guide plate. As the iron unloading belt rotates, the baffle plate slides towards the direction close to the iron unloading L-shaped plate, and the compression spring is compressed. Until the iron unloading L-shaped plate enters the horizontal section of the contraction guide plate, the baffle plate completely contracts, thereby preventing the material on the conveyor belt from being stirred. When the material on the conveyor belt passes directly below the permanent magnet, ferromagnetic impurities are attracted to the surface of the iron unloading belt directly below the permanent magnet. The iron unloading L-shaped plate pushes the ferromagnetic impurities to move. When the iron unloading L-shaped plate moves to one side of the material conveyor belt and does not move out of the strong magnetic area of the permanent magnet, the baffle plate separates from the contraction guide plate. With the cooperation of the compression spring, the baffle plate quickly resets, thereby lengthening the blocking length of the ferromagnetic impurities. When the iron unloading L-shaped plate moves to the weak magnetic area, the iron unloading L-shaped plate and the baffle plate block the ferromagnetic impurities at the same time, preventing the ferromagnetic impurities from swinging back or being sucked back. The suspended permanent magnet iron remover can effectively solve the problems of swinging back and sucking back of ferromagnetic impurities without changing the gap between it and the material conveyor belt, improve the iron removal effect on the material, and protect the material transportation equipment.

The two idler rollers 11 are connected to the two rotating drums 5 through a scrap iron removal belt 14. The permanent magnet 4 is located inside the scrap iron removal belt 14. A number of detachably arranged scrap iron removal L-shaped plates 13 are evenly distributed on the outer surface of the scrap iron removal belt 14. A baffle 12 is vertically slidably arranged at the end of the scrap iron removal L-shaped plate 13. Opposite inner walls of the support frame 3 are fixedly connected with shrinkage guide plates 15. The shrinkage guide plates 15 are divided into an arc section and a horizontal section. The distance between the arc section of the shrinkage guide plate 15 and the scrap iron removal belt 14 gradually decreases along the movement track of the scrap iron removal belt 14. The horizontal section of the shrinkage guide plate 15 is parallel to the scrap iron removal belt 14 and the distance is the same as the minimum distance between the arc section of the shrinkage guide plate 15 and the scrap iron removal belt 14.

[0036] The adjusting component 2 includes a fixed box body 26. Two fixedly arranged upper support cylinders 24 and lower support cylinders 22 are respectively arranged at the top and bottom of the fixed box body 26. Two rotating shafts 23 are rotatably arranged inside the fixed box body 26 along the vertical line. The two rotating shafts 23 are synchronously rotated. Thrust bearings 34 are arranged at the inner top of the upper support cylinder 24 and the inner bottom of the lower support cylinder 22. The two ends of the rotating shaft 23 pass through the fixed box body 26 and respectively enter the upper support cylinder 24 and the lower support cylinder 22 and abut against the thrust bearings 34. The upper support cylinder 24 and the lower support cylinder 22 are both rotatably connected to the rotating shaft 23. An avoidance hole 35 is penetrated through the top of the upper support cylinder 24. A connecting column 30 is hinged to the inner top of the fixed frame 1. A lead screw 25 is fixedly arranged at the bottom of the connecting column 30. The bottom end of the lead screw 25 passes downward through the avoidance hole 35 and extends into the rotating shaft 23 and is threadedly connected to the rotating shaft 23. The lower support cylinder 22 is hinged to the support frame 3.

[0037] Inside the fixed box body 26, there is a driven shaft 28 rotatably arranged along the vertical line. Two driving sprockets 33 are fixedly sleeved on the outer wall of the driven shaft 28. A driven sprocket 31 is fixedly sleeved on the outer wall of the rotating shaft 23. The driving sprocket 33 is connected to the driven sprocket 31 through a driving chain 32. The driven shaft 28 is rotationally connected to the fixed box body 26.

[0038] A worm gear 29 is fixedly sleeved on the outer wall of the driven shaft 28. A worm 27 meshing with the worm gear 29 is rotatably arranged on the inner wall of the fixed box body 26. One end of the worm 27 passes through the fixed box body 26 and extends to the outside and is of a hexagonal prism structure.

[0039] A number of bolt mounting holes 20 are arranged through the surface of the iron unloading belt 14. The iron unloading L-shaped plate 13 is connected to the iron unloading belt 14 through bolts and nuts.

[0040] Positioning shafts 9 are fixedly connected to both ends of the idler roller 11 and the rotating drum 5. A number of bearing seats 10 are fixedly installed at the top and bottom of the support frame 3. One end of the positioning shaft 9 extends into the bearing seat 10 and is rotationally connected to the bearing seat 10.

[0041] A driving motor 8 is fixedly installed at the bottom of the support frame 3. Driving sprockets 7 are fixedly sleeved on the output shaft of the driving motor 8 and the outer wall of one of the positioning shafts 9. The two driving sprockets 7 are connected through a transmission chain 6.

[0042] The contraction guide plate 15 is fixedly connected to the support frame 3 through a number of connecting plates 21.

[0043] The bottom surface of the permanent magnet 4 is in frictional contact with the iron unloading belt 14.

[0044] The working principle of this device is as follows:

[0045] When installing this equipment, the fixed frame 1 is fixedly connected to the material transportation equipment by welding or other means. When adjusting the inclination angle of the permanent magnet separator, use a bolt tightening gun to drive the worm 27 to rotate. Driven by the worm gear 29, the driven shaft 28 rotates. Driven by the driving sprocket 33, the driving chain 32 and the driven sprocket 31, the two rotating shafts 23 rotate synchronously. When the rotating shaft 23 and the lead screw 25 rotate relatively, one end of the support frame 3 rises or falls, so as to adjust the inclination angle of the permanent magnet separator. When adjusting the height of the permanent magnet separator, use a bolt tightening gun to drive the two worms 27 to rotate, so that both ends of the support frame 3 rise or fall by the same height, and then adjust the height of the permanent magnet separator until the lower end surface of the permanent magnet 4 is close to the materials on the conveyor belt. When adjusting the inclination angle and the distance between the permanent magnet separator and the conveyor belt, the four corners of this suspended permanent magnet separator can be adjusted by the method of synchronously adjusting two corners, greatly reducing the adjustment operation and measurement operation, and simplifying the distance adjustment process and parallelism adjustment process between the permanent magnet separator and the conveyor belt;

[0046] When cleaning iron from the materials on the conveyor belt, the driving motor 8 drives one of the rotating drums 5 to rotate, and then drives the iron unloading belt 14 to rotate. When the iron unloading L-shaped plate 13 moves within the arc section of the contraction guide plate 15, the baffle plate 12 abuts against the contraction guide plate 15. As the iron unloading belt 14 rotates, the baffle plate 12 slides towards the direction close to the iron unloading L-shaped plate 13, and the compression spring 19 is compressed. Until the iron unloading L-shaped plate 13 enters the horizontal section of the contraction guide plate 15, the baffle plate 12 completely contracts, thus preventing the materials on the conveyor belt from being stirred. When the materials on the conveyor belt pass directly below the permanent magnet 4, ferromagnetic impurities are attracted to the surface of the iron unloading belt 14 directly below the permanent magnet 4. The iron unloading L-shaped plate 13 pushes the ferromagnetic impurities to move. When the iron unloading L-shaped plate 13 moves to one side of the material conveyor belt and does not move out of the strong magnetic region of the permanent magnet 4, the baffle plate 12 separates from the contraction guide plate 15. With the cooperation of the compression spring 19, the baffle plate 12 quickly resets, thus lengthening the blocking length of the ferromagnetic impurities. When the iron unloading L-shaped plate 13 moves to the weak magnetic region, the iron unloading L-shaped plate 13 and the baffle plate 12 simultaneously block the ferromagnetic impurities to prevent the ferromagnetic impurities from swinging back or being sucked back. This suspended permanent magnet iron remover can effectively solve the problems of the swinging back and sucking back of ferromagnetic impurities without changing the gap between it and the material conveyor belt, improve the iron cleaning effect of the materials, and protect the material transportation equipment.
