Description

Technical Field

[0001] The utility model belongs to the technical field of sorting equipment, and particularly relates to a sorting device for metal recycling. Background Art

[0002] During the waste recycling process, it is necessary to sort metals and non-metals. Waste metals include, but are not limited to, fragments and scraps discarded in the metallurgical industry and metal processing industry, as well as metal objects in scrapped equipment. Although these waste metals have lost their original value, they can still be recycled to save non-renewable energy.

[0003] In a sorting device for metal recycling with the publication number CN 210474301 U, which includes a box body and a conveying frame body. A feeding port is penetrated and opened at the center of the top of the inner cavity of the box body, and a discharging port is penetrated and opened at the bottom of the right side of the inner cavity of the box body. A conveying inclined plate is horizontally and fixedly connected in the inner cavity of the box body. A belt conveyor is installed on the conveying frame body, and a discharging pipe is fixedly connected to the bottom of the right surface of the box body. By using the cooperation of a cleaning frame, a slider, a chute, an electric telescopic rod, a mounting plate, an isolation rubber soft plate, a lifting rod, a storage groove, a connecting rod, a mounting groove, an electromagnet and a connecting rubber plate, the utility model can protect the iron remover of the sorting device, so that the sorting device has a longer service life, and solves the problem that when the sorting device is in use, the iron remover cannot be protected, so that the iron remover collides with iron objects, resulting in easy damage to the sorting device.

[0004] However, when the above device is sorting, the electromagnet above the belt conveyor adsorbs the magnetic metals below, so as to sort out the magnetic metals. The electromagnet can only adsorb metal materials with magnetism, which limits the application range of the device when dealing with complex materials. When the waste materials to be processed contain a large amount of magnetic metals, the electromagnet may adsorb too many metals, resulting in an overly thick metal layer on the electromagnet, thus affecting the sorting efficiency and accuracy. At the same time, the device is not provided with a cleaning device. The accumulation of dust and debris on the conveyor belt not only affects the mechanical part, but also may contaminate the passing metal waste, reducing the quality of the finally sorted metals and causing the sorting efficiency to decline. Therefore, to solve the above problems, a sorting device for metal recycling is proposed. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide a sorting device for metal recycling with high practicability, which can be operated simply and has a relatively simple structure.

[0006] To solve the above technical problems, a sorting device for metal recycling provided by the present utility model includes: a conveyor belt installed above a conveying frame body, a feeding hopper is arranged on the right side of the conveying frame body, mounting blocks are fixed on the front and rear sides of the conveying frame body, a mounting shaft is clamped above the mounting blocks, the mounting shaft is inserted into the interior of a cleaning brush, and the cleaning brush is fixed on the mounting blocks through the mounting shaft. A sorting box body is placed on the left side of the conveying frame body. A permanent magnet drum is rotatably connected inside the sorting box body. A baffle is arranged on the left side of the permanent magnet drum, and a second collection box and a first collection box are respectively placed on the left and right sides of the baffle, and the second collection box and the first collection box are respectively filled with non-ferrous metals and non-metals. A pull rod is fixed on the second collection box.

[0007] As a further solution of the present utility model, the feeding hopper has a structure with an interior sloping downwards to the lower left, and the discharge port at the bottom of the feeding hopper is higher than the conveyor belt above the conveying frame body. The feeding hopper enables the materials to move evenly onto the conveyor belt.

[0008] As a further solution of the present utility model, there are a total of six mounting blocks, with two in a group and fixed oppositely on the front and rear sides of the conveying frame body. The three groups of mounting blocks are fixed on the conveying frame body at the same interval.

[0009] As a further solution of the present utility model, one mounting shaft is placed on each group of mounting blocks. Both ends of the mounting shaft have a rectangular structure that matches the mounting blocks, so that the mounting shaft is fixed on the mounting blocks and prevents the mounting shaft from rotating.

[0010] As a further solution of the present utility model, the cleaning brush has a cylindrical structure, and after installation, the top of the cleaning brush contacts the bottom of the upper part of the conveying frame body. The cleaning brush cleans by friction with the rotating conveyor belt through its top.

[0011] As a further solution of the present utility model, the permanent magnet drum is fixed inside the sorting box body below the conveyor belt, and there are four evenly distributed retaining bars on the permanent magnet drum. The retaining bars will block light or small materials to prevent the materials from slipping from the rear of the permanent magnet drum.

[0012] As a further solution of the present utility model, a baffle is fixed on one side of the bottom of the sorting box body away from the permanent magnet drum. The baffle separates non-ferrous metals and non-metals.

[0013] As a further solution of the present utility model, a groove for conveniently pulling out the first collection box is provided on the front side of the sorting box body on the side of the baffle close to the permanent magnet drum, which facilitates pulling out the first collection box for cleaning and replacement.

[0014] Compared with the related technology, a sorting device for metal recycling provided by the present utility model has the following beneficial effects:

[0015] 1. The utility model is provided with a sorting box body and a permanent magnet roller. The high-intensity magnetic field generated by the permanent magnet roller can accurately identify and separate non-ferrous metals, such as copper, aluminum, etc. Even in complex material mixtures, high separation efficiency can be achieved. This high-efficiency separation ability ensures that valuable non-ferrous metals can be fully recycled. Moreover, the permanent magnet roller generates a repulsive force on non-ferrous metals through rotation, separating them from the material flow, and there will be no situation where an electromagnet may adsorb too much metal, resulting in an overly thick metal layer and affecting the sorting efficiency and accuracy.

[0016] 2. The utility model is provided with a mounting block and a cleaning brush on the conveying frame body. Through the clamping design of the mounting shaft and the fixing block, the cleaning brush is designed to be easily detachable. The cleaning brush makes the cleaning work of the conveyor belt rapid and simple, and it can be disassembled and cleaned without complex tools, improving the overall operating efficiency of the equipment. Moreover, the cleaning brush timely cleans the particulate impurities on the conveyor belt, preventing the particulate impurities from embedding in the conveyor belt and causing damage to the surface of the conveyor belt.

[0025] Please refer to Figure 1-6, A sorting device for metal recycling, comprising: a conveyor belt 2 installed above a conveyor frame 1, a feed hopper 3 provided on the right side of the conveyor frame 1, mounting blocks 4 fixed on the front and rear sides of the conveyor frame 1, a mounting shaft 5 clamped above the mounting blocks 4, the mounting shaft 5 inserted into the interior of a cleaning brush 6, and the cleaning brush 6 fixed to the mounting blocks 4 through the mounting shaft 5. As the conveyor belt 2 rotates, the cleaning brush 6 frictionally cleans the top conveyor belt 2, removing particulate impurities on the conveyor belt 2 and preventing the particulate impurities from embedding in the conveyor belt 2. A sorting box body 7 is placed on the left side of the conveyor frame 1, a permanent magnet drum 8 is rotatably connected inside the sorting box body 7, a baffle 10 is provided on the left side of the permanent magnet drum 8, and a second collection box 11 and a first collection box 9 are respectively placed on the left and right sides of the baffle 10. The permanent magnet drum 8 generates a changing magnetic field through rotation, causing non-ferrous metals 14 to generate eddy currents and be subjected to repulsive forces, moving to the side away from the permanent magnet drum 8 and thus falling into the second collection box 11 on the left side of the baffle 10. Moreover, the second collection box 11 and the first collection box 9 are respectively filled with non-ferrous metals 14 and non-metals 13, and a pull rod 12 is fixed on the second collection box 11.

[0026] The feed hopper 3 has a structure with an interior that slopes downward to the lower left, and the discharge port at the bottom of the feed hopper 3 is higher than the conveyor belt 2 above the conveyor frame 1. When materials are placed into the feed hopper 3, the materials placed in the feed hopper 3 will be carried out of the feed hopper 3 as the conveyor belt 2 rotates, enabling the materials to be evenly arranged on the conveyor belt 2.

[0027] There are a total of six mounting blocks 4, with two in a group and oppositely fixed on the front and rear sides of the conveyor frame 1. The three groups of mounting blocks 4 are fixed on the conveyor frame 1 at the same interval. One mounting shaft 5 is placed on each group of mounting blocks 4. The cleaning brush 6 has a cylindrical structure. The two sides of the mounting shaft 5 inserted into the cleaning brush 6 are respectively fixed above the mounting blocks 4 on both sides. After installation, the top of the cleaning brush 6 contacts the bottom of the conveyor frame 1. As the conveyor belt 2 rotates, the cleaning brush 6 frictionally cleans the top conveyor belt 2, removing particulate impurities on the conveyor belt 2 and preventing the particulate impurities from embedding in the conveyor belt 2. The rectangular structure design at both ends of the mounting shaft 5 restricts the movement of the cleaning brush 6, and the cleaning brush 6 can be disassembled for cleaning by removing the mounting shaft 5 from the mounting block.

[0028] The permanent magnet drum 8 is fixed inside the sorting box body 7 below the conveyor belt 2, and four evenly distributed retaining bars are provided on the permanent magnet drum 8. The retaining bars will block light or small materials to prevent them from slipping from the rear of the permanent magnet drum 8. A baffle 10 is fixed on one side of the bottom of the sorting box body 7 away from the permanent magnet drum 8. A groove for conveniently pulling out the first collection box 9 is provided on the front side of the sorting box body 7 on the side close to the permanent magnet drum 8. The working principle of the permanent magnet drum 8 is based on the eddy current effect. That is, when non-ferrous metal 14 (a conductor) moves in a changing magnetic field, closed vortex-shaped induced currents will be generated inside the non-ferrous metal 14. This kind of current is called an eddy current. The eddy current itself will generate a new magnetic field opposite to the direction of the original magnetic field, thereby generating a repulsive force on the non-ferrous metal 14 and separating it from the material flow. By applying a high-frequency alternating strong magnetic field to the conductive non-ferrous metal 14, eddy currents are generated and a repulsive force is received, causing it to move to the side away from the permanent magnet drum 8, thus realizing the separation from other non-metal 13 substances.

[0029] Working principle: Before using the device, ensure that the surfaces of the conveyor belt 2 and the permanent magnet drum 8 are clean, and prepare the materials from which magnetic metals have been sorted out.

[0030] Fix both sides of the mounting shaft 5 inserted on the cleaning brush 6 above the mounting blocks 4 on both sides respectively, so that the top of the cleaning brush 6 contacts the bottom of the upper part of the conveying frame body 1.

[0031] Turn on the conveyor belt 2 and let it run at a low speed. Observe whether there are abnormal sounds or jamming phenomena. After ensuring that the conveyor belt 2 is working properly, start the permanent magnet drum 8 and adjust it to the preset speed. Put the materials into the feed hopper 3. The materials placed in the feed hopper 3 will be carried out of the feed hopper 3 as the conveyor belt 2 rotates, and the materials will be evenly arranged on the conveyor belt 2.

[0032] When the materials on the conveyor belt 2 move to the leftmost side, they will fall onto the permanent magnet drum 8. As the permanent magnet drum 8 rotates, closed vortex-shaped induced currents will be generated inside the non-ferrous metal 14, generating a new magnetic field opposite to the direction of the original magnetic field. The permanent magnet drum 8 will thus generate a repulsive force on the non-ferrous metal 14, separating it from the materials and falling into the second collection box 11 on the left side of the baffle 10. The non-metal 13 in the materials will fall into the first collection box due to gravity.

[0033] As the conveyor belt 2 rotates, the cleaning brush 6 will frictionally clean the top conveyor belt 2 to remove particulate impurities on the conveyor belt 2, preventing the particulate impurities from embedding in the conveyor belt 2. Along with the operation of the device, there may still be smaller magnetic metals in the material. Regularly clean the debris on the permanent magnet drum 8, and remove the cleaning brush 6 through the mounting shaft 5 for cleaning. When the non-metals 13 and non-ferrous metals 14 accumulate almost full in the first collection box 9 and the second collection box 11, pull out the first collection box 9 and the second collection box 11 and replace them with new first collection box 9 and second collection box 11 inside the sorting box body 7 for collection, and place the collected non-metals 13 and non-ferrous metals 14 in appropriate storage locations.

[0034] After sorting is completed, first turn off the power supply, and clean the residues on the conveyor belt 2, the feed hopper 3, and the permanent magnet drum 8 to keep the equipment clean.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, or directly or indirectly applied. In other related technical fields, the scope of the present invention is defined by the appended claims and their equivalents, and is similarly included within the scope of the patent protection of the present invention.
