Description

Technical Field

[0001] The invention belongs to the technical field of magnetic separation, and in particular relates to a magnetic separation device for metal material production. Background Art

[0002] Under the current complex and diverse industrial production pattern, various industries such as metal processing, machinery manufacturing, and electronic and electrical assembly are booming, and a large amount of production waste is continuously produced. Among them, those metal wastes with ferromagnetic properties and can be adsorbed by magnetism, such as scrap steel scraps, discarded iron parts, and obsolete magnetic alloy fragments, are often intricately mixed with a variety of other wastes. Take the steel foundry as an example. During the cutting, grinding and machining of the ingot, iron filings and iron sheets of various shapes and sizes will be produced, accompanied by sand mold waste, ceramic insulation waste slag, plastic protective scraps, etc. In the electronic waste disassembly workshop, the residues after the circuit board is disassembled contain not only tiny ferromagnetic metal pins and shielding cover fragments, but also glass fiber substrates, non-magnetic non-ferrous metal particles and various organic insulating materials. These mixed wastes are piled together like a mess, which creates a difficult problem for the subsequent recycling work.

[0003] Traditional manual sorting methods are inefficient and extremely labor-intensive. Workers need to work in harsh environments for a long time, relying on their naked eyes and simple tools to identify metal waste that can be magnetically absorbed from piles of waste. If they are careless, they may miss it, and it is difficult to guarantee the accuracy of sorting when faced with small and complex waste. Mechanical screening methods, such as simple vibrating screens and air separation equipment, are effective in sorting waste with obvious differences in density and particle size, but once they encounter the situation of magnetic and non-magnetic waste sticking or wrapping, they are helpless and cannot accurately separate the metal waste that can be magnetically absorbed.

[0004] In view of this, it is urgent to develop and equip a set of efficient, intelligent, stable and reliable magnetic separation devices. This device needs to cleverly integrate cutting-edge magnetic technology, use high-intensity, flexibly controllable magnetic fields, accurately capture ferromagnetic metal components in mixed waste; with automated loading, transmission and discharging systems, to achieve continuous and orderly flow of materials, reduce manual intervention, and improve separation efficiency.

DETAILED DESCRIPTION

[0022] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 8As shown, a magnetic separation device for metal material production provided by an embodiment of the present invention comprises a conveyor belt mechanism 1, a frame 2 is arranged above the conveyor belt mechanism 1, a lifting platform 3 is arranged at the lower side of the frame 2, a circular turntable 4 is installed at the lower side of the lifting platform 3, the circular turntable 4 is arranged above the conveyor belt mechanism 1, and the diameter of the circular turntable 4 is greater than the width of the conveyor belt mechanism 1, and a plurality of electromagnets 5 are installed at the lower edge of the circular turntable 4; It also includes a metal recovery trough 6, which is located on both sides of the conveyor belt mechanism 1 and below the circular turntable 4, and is used to collect the fallen metal materials.

[0025] When used, the magnetic separation device for metal material production comprises the following steps: Material conveying preparation stage: The garbage material is placed at the starting end of the conveyor belt mechanism 1, and the conveyor belt mechanism 1 starts to operate under power drive, continuously conveying the garbage material at a stable speed, and moving steadily towards the area below the circular turntable 4, providing a continuous and orderly material flow for the subsequent magnetic screening operation.

[0026] Magnetic attraction screening stage: When the conveyor belt mechanism 1 transports the garbage material to the position directly below the circular turntable 4, the lifting platform 3 located at the lower side of the frame 2 begins to descend steadily, driving the circular turntable 4 installed at its lower side to move downward together, until the electromagnets 5 installed at the lower edge of the circular turntable 4 approach or contact the garbage material on the conveyor belt mechanism 1. Since the electromagnet 5 has a strong and stable magnetic field, according to the principle of magnetic attraction, the ferromagnetic substances such as iron metal in the garbage material will overcome their own gravity and the friction between the materials under the action of the magnetic field, and be adsorbed on the surface of the electromagnet 5, thereby achieving preliminary separation from other non-ferromagnetic garbage materials.

[0027] Metal collection and transfer stage: After the magnetic suction screening process lasts for a period of time and ensures that as much iron metal as possible is adsorbed, the lifting platform 3 starts to rise, lifting the circular turntable 4 together with the electromagnet 5 adsorbing the iron metal material to a certain height, and breaking away from the contact with the rest of the material on the conveyor belt mechanism 1. Then, the circular turntable 4 starts to rotate, and the rotation direction is adjusted to the position above the pre-set metal recovery slot 6. When the circular turntable 4 is in place, the magnetic adsorption effect of the corresponding electromagnet 5 is turned off by controlling the electromagnetic circuit of the electromagnet 5. After the iron metal material originally adsorbed on the electromagnet 5 loses magnetic adsorption, it slides down the metal recovery slot 6 (slide form design) under the action of gravity, and is finally collected, completing the whole process of separating and recovering iron metal materials from garbage materials. Subsequent devices can work in this way in a reciprocating manner to continuously process the garbage materials that are continuously transported.

[0028] The above scheme has the following beneficial effects: First, by using the powerful and stable magnetic force of the electromagnet 5, the iron metal in the garbage material can be accurately adsorbed, and the iron metal can be efficiently screened and separated from the complex mixed garbage material, thereby improving the metal recycling efficiency, reducing the subsequent complex processes such as manual sorting, and reducing the labor cost and time cost investment. For example, in the material processing scene after the dismantling of waste electronic products, the iron metal parts can be quickly sucked out and recycled among the mixed materials of many fine parts.

[0029] Second, the entire device is based on the coordinated layout of the conveyor belt mechanism 1, the lifting platform 3, the circular turntable 4 and the metal recovery trough 6, and uses the up and down and rotating spatial dimensions. The frame 2 carries the lifting platform 3 and the circular turntable 4, which are compactly and neatly placed above the conveyor belt mechanism 1 without taking up too much extra space; the metal recovery trough 6 is designed with slideways on both sides of the conveyor belt mechanism 1, which fits the recycling process and facilitates the export of metal materials. The overall space utilization rate is high, and it is easy to flexibly place and arrange in various places such as the production line of the factory workshop and small recycling stations.

[0030] Third, through the automatic control of the rotation of the lifting platform 3 and the circular turntable 4 (connected to the PLC control system, the preset program can realize one-button start and stop, and automatic cycle operation), and the magnetic on-off control of the electromagnet 5, the operator only needs to load the materials and debug the equipment before starting the device, and monitor the status during operation. There is no need for complicated manual intervention, which reduces labor intensity. The equipment start and stop, and parameter adjustment are simple, and it can be quickly and flexibly adapted to different material processing volumes and iron metal content differences.

[0031] Fourth, from the perspective of resource recovery, the iron metal in the waste material can be efficiently recycled and reused, reducing the demand for mining and smelting of primary metal ores, and reducing energy consumption and waste emissions; at the operating level of the device itself, the electromagnet 5 does not require continuous electrical energy to maintain magnetism, and the overall energy consumption is low.

[0032] Exemplarily, the conveyor belt mechanism 1 includes: a frame 11, a conveyor belt 12, and a limit baffle 13; the conveyor belt 12 is arranged on the frame 11, the limit baffle 13 is fixedly connected to the top of the frame 11, and the limit baffle 13 is located on both sides of the conveyor belt 12. It should be noted that the conveyor belt 12 is driven by a motor and a roller shaft, which is a prior art and will not be described in detail here.

[0033] Exemplarily, the lifting platform 3 includes: a hydraulic rod 31, a connecting plate 32, a connecting rod 33, a connecting ring 34 and a bearing platform 35; the hydraulic rod 31 is fixedly connected to the bottom of the frame 2, the lower end of the hydraulic rod 31 is fixedly connected to the upper surface of the connecting plate 32, the lower surface edge of the connecting plate 32 is fixedly connected to the upper end of the connecting rod 33, the lower end of the connecting rod 33 is fixedly connected to the connecting ring 34, and the connecting ring 34 is fixedly connected to the bearing platform 35 by bolts.

[0034] Exemplarily, the circular turntable 4 includes a motor 41, a first rotating shaft and a turntable body 42; The motor 41 is fixedly connected to the upper surface of the carrying platform 35; The first rotating shaft is fixedly connected to the output shaft of the motor 41 through a coupling; The disk body 42 is fixedly connected to the first rotating shaft.

[0035] Exemplarily, the disk body 42 includes a circular plate 421, a connecting frame 422, and an outer ring 423; The center of the circular plate 421 is fixedly connected to the first rotating shaft; One end of the connecting frame 422 is fixedly connected to the outer circumferential surface of the circular plate 421 , and the other end of the connecting frame 422 is fixedly connected to the outer ring 423 . The outer ring 423 and the circular plate 421 are coaxial.

[0036] Furthermore, the electromagnet 5 is mounted on the lower surface of the disk 42, and a plurality of push switches 51 are fixedly connected to the upper surface of the disk 42, and the push switches 51 correspond to the electromagnet 5 one by one, and the push switches 51 are connected to the electromagnet 5 by signal; and a blocking rod is also included, and when the push switch 51 passes through the blocking rod, the blocking rod presses the push switch 51 to trigger the closing mechanism of the electromagnet 5. A blocking rod is set on the rotation path of the disk 42, and when the disk 42 rotates to a specific position, the switch above the electromagnet 5 will touch the blocking rod. When the switch touches the blocking rod, the closing mechanism of the electromagnet is triggered, causing the electromagnet 5 to lose its magnetic force. When the disk 42 continues to rotate and leaves the blocking rod, the switch is reset, the electromagnet is powered on again, and the electromagnet 5 restores its magnetic force.

[0037] Furthermore, the frame 2 includes a vertical frame 21 and a horizontal frame 22, the vertical frame 21 is fixedly connected to the frame body 11, the horizontal frame 22 is slidably connected to the top of the vertical frame 21, and the lifting platform 3 is fixedly connected to the lower surface of the horizontal frame 22; the blocking rod includes a first sub-rod 71 and a second sub-rod 72, the first sub-rod 71 is fixedly connected to the connecting rod 33, and the second sub-rod 72 is installed on the vertical frame 21.

[0038] With this setup, the device has two working positions: First, the circular turntable 4 is located directly above the conveyor belt 12, and both sides of the circular turntable 4 extend to the outside of the conveyor belt 12. At this time, the first sub-rod 71 and the second sub-rod 72 can close the electromagnets 5 corresponding to the two sides of the circular turntable 4 respectively.

[0039] Second, the horizontal frame 22 moves to one side, for example, by driving the horizontal frame 22 to move through an electric slide, which can drive the entire lifting platform 3 and the circular turntable 4 to move, so that only one side of the circular turntable 4 extends to the outside of the conveyor belt 12. Assuming that the left side of the circular turntable 4 extends to the outside of the conveyor belt 12, the front, rear, and right sides of the circular turntable 4 can all absorb metal materials to improve efficiency. At this time, the first sub-rod 71 moves synchronously and can still press the push-type switch 51 on the left side. The second sub-rod 72 does not move, so it will not press the push-type switch 51 on the right side, thereby not affecting the operation of the electromagnet 5 on the right side.

[0040] Preferably, the suction forces of the electromagnets 5 are different.

[0041] Exemplarily, a cross bar 81 is fixedly connected to the connecting ring 34, and an arc-shaped rack 82 is fixedly connected to the end of the cross bar 81; a second rotating shaft 83 is rotatably connected to the connecting frame 422 through a bearing, and a gear 84 is fixedly connected to the upper end of the second rotating shaft 83, and the gear 84 is meshed with the arc-shaped rack 82; a dial wheel 85 is fixedly connected to the lower end of the second rotating shaft 83; When in use, the circular turntable 4 can be rotated back and forth. Since the arc-shaped rack 82 does not rotate, the gear 84 can drive the second rotating shaft 83 and the dial wheel 85 to rotate, thereby shifting the material to facilitate the adsorption of the electromagnet 5.

[0042] Furthermore, a distribution mechanism 9 is provided in the middle of the disk body 42, which is used to move the garbage material to disperse it and increase the exposure opportunity of the metal material. The distribution mechanism 9 includes an elastic telescopic rod 91, and a plurality of paddles 92 are annularly installed on the lower side of the elastic telescopic rod 91. Through this arrangement, the garbage material enters the conveyor belt mechanism 1 through the feed hopper and is evenly distributed on the conveyor belt mechanism 1. When rotating to the front of the conveyor belt mechanism 1, the electromagnet 5 in the front part of the circular turntable 4 adsorbs the metal material on the conveyor belt mechanism 1. The garbage material continues to move forward with the conveyor belt mechanism 1, and when passing through the distribution mechanism 9, the paddle 92 will move the garbage material to disperse it, increasing the exposure opportunity of the metal material. When the garbage material continues to move forward and reaches the rear of the circular turntable 4, the electromagnet 5 in the rear part adsorbs the metal material on the conveyor belt mechanism 1 again. Preferably, the paddle 92 can also be set as a spiral blade, which can push the material upward when rotating, and turn out the metal material pressed below, so as to facilitate the subsequent magnetic adsorption.

[0043] Working principle of the present invention: The garbage material is placed at the starting end of the conveyor belt mechanism 1. The conveyor belt mechanism 1 starts to operate under the power drive, continuously transporting the garbage material at a stable speed, and steadily moving forward towards the area below the circular turntable 4, providing a continuous and orderly material flow for the subsequent magnetic screening operation. When the conveyor belt mechanism 1 transports the garbage material to the position directly below the circular turntable 4, the lifting platform 3 located on the lower side of the frame 2 begins to descend steadily, driving the circular turntable 4 installed on its lower side to move downward together, until the several electromagnets 5 installed on the lower edge of the circular turntable 4 approach or contact the garbage material on the conveyor belt mechanism 1. Since the electromagnet 5 has a strong and stable magnetic field, according to the principle of magnetic adsorption, the ferromagnetic substances such as iron metal in the garbage material will overcome their own gravity and the friction between the materials under the action of the magnetic field, and be adsorbed on the surface of the electromagnet 5, thereby achieving preliminary separation from other non-ferromagnetic garbage materials. After the magnetic suction screening process lasts for a period of time and ensures that as much iron and metal as possible is adsorbed, the lifting platform 3 starts to rise, lifting the circular turntable 4 and the electromagnet 5 adsorbing the iron and metal materials to a certain height, and breaking away from the contact with the rest of the materials on the conveyor belt mechanism 1. Then, the circular turntable 4 starts to rotate, and the rotation direction is adjusted to the position above the pre-set metal recovery slot 6. When the circular turntable 4 is in place, the magnetic adsorption effect of the corresponding electromagnet 5 is turned off by controlling the electromagnetic circuit of the electromagnet 5. After the iron and metal materials originally adsorbed on the electromagnet 5 lose magnetic adsorption, they slide down the metal recovery slot 6 under the action of gravity and are finally collected, completing the whole process of separating and recovering iron and metal materials from garbage materials. Subsequent devices can work in this way in a reciprocating manner to continuously process the garbage materials that are continuously transported.
