Technical Field

[0001] The invention relates to the technical field of magnetic separators, and in particular to a belt-type automatic magnetic separator. Background Art

[0002] Magnetic separator is one of the most widely used and versatile machines in the industry, suitable for separating materials with magnetic differences. Magnetic separators are widely used in mining, wood, kiln, chemical, food and other industries.

[0003] When the existing belt magnetic separator is used for sorting, it is inconvenient to apply vibration force to the belt because the materials are mixed together. Using a motor to apply vibration not only makes the equipment structure complex and noisy, but also the materials are easily spilled due to the vibration method. The effect of magnetic separation is not ideal, and the separation of different components is not thorough enough. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a belt-type automatic magnetic separator with simple structure, low noise, and material not easy to spill and different components can be sorted thoroughly.

[0005] To solve the above technical problems, the present invention includes a bracket, magnetic rollers are respectively installed at both ends of the bracket, a conveyor belt is installed between the two magnetic rollers, one of the magnetic rollers is connected to a driving motor, a feeding device is arranged on the upper side of the rear end of the conveyor belt, a magnetic plate supporting the inner bottom surface of the conveyor belt is arranged on the upper side between the two magnetic rollers, a first conveyor belt assembly is arranged at the bottom of the front end of the conveyor belt, a second conveyor belt assembly is arranged on the lower side of the conveyor belt, a scraper is arranged at the bottom of the conveyor belt, and the scraper is attached to the bottom surface of the conveyor belt; the conveyor belt is formed by a plurality of hard plates and soft plates alternately and fixedly connected in sequence, a cavity is provided inside the soft plate, folding airbags are arranged at both ends of the hard plate, side plates are symmetrically arranged on both sides of the upper part of the conveyor belt, the side plates are fixedly connected to the bracket, a plurality of extrusion pieces extending inwardly are arranged on the inner side of the side plates along the direction of the conveyor belt, the folding airbag is connected to the cavity adjacent to one side, the extrusion pieces on the inner sides of the two side plates are staggered, and the folding airbag is squeezed when passing through the extrusion piece.

[0006] In order to prevent materials from spilling, a first material receiving hopper is arranged at the bottom of the front end of the conveyor belt, and the first material receiving hopper is located on the upper side of the first conveyor belt assembly.

[0007] In order to prevent materials from spilling, a second material receiving hopper is arranged at the lower side of the conveyor belt, and the second material receiving hopper is located at the upper side of the second conveyor belt assembly.

[0008] Preferably, the folded airbag is a fan-shaped airbag.

[0009] In order to better extrude the folded airbag and deform it, a rotating plate is arranged on the outside of the folded airbag, one end of which is hingedly connected to the end of the hard plate. The extruder can extrude the outer side of the rotating plate to deform the folded airbag, and a torsion spring is installed at the hinge axis of the rotating plate.

[0010] In order to improve the deflection effect of the hard plate, a collision block is arranged on the inner side of the rotating plate, and the collision block can contact the end of the hard plate.

[0012] In order to prevent materials from spilling, the outer surfaces of the joints between the hard plate and the soft plate are flush, and guard bars are provided on the outer surface of the conveyor belt near both sides.

[0013] To sum up, when the present invention is used, the feeding device adds the granular material to be sorted to the surface of the conveyor belt. The conveyor belt is constantly offset, vibrated and intermittently expanded and deformed in the process of conveying the material. In this process, the material on the conveyor belt is constantly rolling. Under the attraction of the magnetic plate, the impurities that can be attracted by the magnetic force will slowly sink to the bottom and be adsorbed on the surface of the conveyor belt. When the material is located on the upper side of the conveyor belt, the impurities that can be attracted by the magnetic force can sink to the bottom, and the material is fully stratified. Therefore, the impurities that can be attracted by the magnetic force are not easy to fall into the first receiving hopper with other components, so that the sorting is more thorough.

[0020] See attached Figure 1-5The belt-type automatic magnetic separator comprises a bracket 1, magnetic rollers 2 are respectively installed at both ends of the bracket 1, a conveyor belt 3 is installed between the two magnetic rollers, one of the magnetic rollers is connected to a driving motor, a feeding device 4 is arranged on the upper side of the rear end of the conveyor belt 3, a magnetic plate 5 supporting the inner bottom surface of the conveyor belt is arranged on the upper side between the two magnetic rollers 2, a first receiving hopper 6 is arranged at the bottom of the front end of the conveyor belt, a first conveyor belt assembly 7 is arranged at the lower part of the first receiving hopper 6, a second receiving hopper 8 is arranged on the lower side of the conveyor belt, a second conveyor belt assembly 9 is arranged at the lower part of the second receiving hopper, a scraper 10 is arranged at the bottom of the conveyor belt, and the scraper 10 is attached to the bottom surface of the conveyor belt.

[0021] The conveyor belt is composed of multiple hard plates 11 and soft plates 12 that are alternately fixed and connected in sequence. The soft plate 12 has a cavity 13 inside. The soft plate can be made of deformable materials such as rubber. Folding airbags 14 are set at both ends of the hard plate, and side panels 15 are symmetrically set on both sides of the upper part of the conveyor belt. The side panels are fixedly connected to the bracket. Several extrusions 16 extending inwardly are set on the inner side of the side panels along the conveyor belt direction. The folding airbag is connected to the cavity 13 adjacent to one side. The extrusions on the inner sides of the two side panels are staggered. The folding airbag is squeezed when passing through the extrusions. The internal air of the folding airbag enters the corresponding cavity after being squeezed, and the soft plate 12 is inflated and expanded. At this time, the extrusion applies a thrust to the other side to the corresponding hard plate through the folding airbag. Under the action of the thrust, the hard plate is offset to one side by a certain distance. Since the soft plate 12 has a certain deformation ability, the two adjacent hard plates are pushed in opposite directions and offset a little distance in different directions. Due to inertia, the material will roll relative to the hard plate. With the intermittent expansion of the soft plate, the material on the conveyor belt will continue to roll. Under the attraction of the magnetic plate, the impurities that can be attracted by the magnetic force will slowly sink to the bottom and be adsorbed on the surface of the conveyor belt. When the material passes through the magnetic roller with the conveyor belt, other components that are not adsorbed will fall to the first conveyor belt assembly 7 after passing through the first receiving hopper 6 and be transported to other processes. The impurities that can be attracted by the magnetic force will fall to the second conveyor belt assembly 9 after passing through the second receiving hopper and be transported and collected. In this process, when the material is located on the upper side of the conveyor belt, the impurities that can be attracted can sink to the bottom, and the material can be fully stratified, so the impurities that can be attracted by the magnetic force are not easy to fall into the first receiving hopper with other components.

[0022] The folding airbag 14 is a fan-shaped airbag. A rotating plate 17 is arranged on the outside of the folding airbag. One end of the rotating plate is hingedly connected to the end of the hard plate. The extrusion piece can squeeze the outer side surface of the rotating plate to deform the folding airbag. A torsion spring is installed at the hinge axis of the rotating plate 17. After the extrusion piece is separated from the rotating plate, the torsion spring can assist the folding airbag to return to its original state.

[0023] A collision block 18 is arranged on the inner side of the rotating plate 17. After the rotating plate rotates to a certain extent around the hinge, the collision block contacts the end of the hard plate, which can more directly push the hard plate to deflect and collide with the hard plate to make it vibrate, thereby more effectively rolling the material.

[0024] A plurality of evenly distributed first magnetic blocks 19 are embedded on the upper surface of the magnetic plate, and a plurality of evenly distributed second magnetic blocks 20 are embedded on the outer surface of the magnetic roller.

[0025] A sleeve 21 is set on one side of the second receiving hopper, and the scraper is connected to the upper end of the L-shaped rod 22. The lower end of the L-shaped rod is inserted into the sleeve. A fastening screw 23 is set on one side of the sleeve. The inner end of the fastening screw is against the lower end side of the L-shaped rod. The L-shaped rod can be fixed by the fastening screw. This design can facilitate the adjustment of the height and angle of the scraper, and the scraper can ensure that impurities adhering to the conveyor belt are cleaned up.

[0026] The outer surfaces of the joints of the hard plate and the soft plate are flush, and barrier strips 24 are arranged near both sides of the outer surface of the conveyor belt. This design can prevent materials from spilling from the sides of the conveyor belt.

[0027] Working principle: When in use, the feeding device adds the granular material to be sorted to the surface of the conveyor belt. The conveyor belt is constantly offset and intermittently expanded and deformed during the process of conveying the material. During this process, the material on the conveyor belt is constantly rolling. Under the attraction of the magnetic plate, the impurities that can be attracted by the magnetic force will slowly sink to the bottom and be adsorbed on the surface of the conveyor belt. When the material is on the upper side of the conveyor belt, the impurities that can be attracted by the magnetic force can sink to the bottom, and the material can be fully stratified. Therefore, the impurities that can be attracted by the magnetic force are not easy to fall into the first receiving hopper with other components, so that the sorting is more thorough.

[0028] Compared with the fixed-frequency vibration mode of traditional motors, this device uses a special conveyor belt structure design to reduce the complexity of the overall equipment, reduce the noise of the equipment, and use inertia to make the material roll relative to the conveyor belt and tumble above the conveyor belt. In this way, the material will not bounce due to vibration, and can be spread more evenly on the conveyor belt without easily spilling to the outside of the conveyor belt.

[0029] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
