Description

Technical Field

[0001] This utility model belongs to the field of magnetic steel recycling technology, specifically a screening device for recycling waste magnetic steel. Background Technology

[0002] Magnet steel is an important permanent magnet material, mainly referring to AlNiCo alloy, which is synthesized from hard and strong metals such as iron, aluminum, nickel, and cobalt. Sometimes it also contains elements such as copper, niobium, and tantalum. It is used to make ultra-hard permanent magnet alloys. Magnet steel has the characteristics of high coercivity, high remanence, and wide hysteresis loop. The recycling of magnet steel has high economic value and environmental significance. Because it contains precious metals such as cobalt and nickel, screening devices are key equipment in the magnet steel recycling process. They are mainly used to separate impurities from the recycled magnet steel waste. When using existing screening devices, magnet steel is generally poured into the screening device by tilting, and then screened by magnetic attraction. The screened magnet steel is attracted to the electromagnetic suction plate. Since the electromagnetic suction plate is fixed inside the screening device and is difficult to disassemble, it is difficult to remove the screened magnet steel from the screening device. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a screening device for recycling waste magnets, which solves the problem that existing screening devices generally pour magnets into the screening device by tilting, and then screen the magnets by magnetic attraction. The screened magnets are attracted to the electromagnetic suction plate, which is fixed inside the screening device and difficult to disassemble, making it difficult to remove the screened magnets from the screening device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a screening device for recycling waste magnets, comprising a screening box, a fixed frame fixedly connected to the middle position inside the screening box, multiple sliding rods slidably connected through both sides of the fixed frame, the sliding rods being in groups of three, one end of each group of sliding rods passing through the fixed frame and fixedly connected to a fixed plate, the ends of two groups of sliding rods away from the fixed plate being fixedly connected to a sliding frame, and the sliding frame slidingly connected to both sides inside the fixed frame, a spring sleeved on the surface of each sliding rod between the sliding frame and the inner wall of the fixed frame, a plug-in block slidably connected through the inner wall of the sliding frame, a placement box fixedly connected between two plug-in blocks, a screening screen fixedly connected to the bottom of the placement box, an installation plate slidably connected to one side of the placement box, a collection drawer slidably connected through the bottom of the screening box, a snap-fit ​​seat fixedly connected to the top of one side of the installation plate, and a plug-in seat fixedly connected to the top of the snap-fit ​​seat of the screening box, the plug-in seat engaging with the snap-fit ​​seat.

[0005] As a further embodiment of this utility model: a motor is fixedly connected to one side of the screening box, and the motor is provided with a rotating rod through the output shaft. The rotating rod is rotatably connected to the inner wall of the screening box through a bearing.

[0006] As a further embodiment of this utility model: the rotating rod is symmetrically and fixedly connected to both ends inside the screening box with cams, and the cams are in close contact with the fixing plate.

[0007] As a further embodiment of this utility model: a mounting frame is fixedly connected to the top of the screening box, and an electric telescopic rod is fixedly connected inside the mounting frame.

[0008] As a further embodiment of this utility model: a fan is fixedly connected to the side of the screening box away from the collection drawer, the fan is connected to the inside of the screening box, a flexible hose is fixedly connected to the top of the fan, and an air outlet frame is installed through the mounting frame at the end of the flexible hose away from the fan, and the air outlet frame is fixedly connected to the electric telescopic rod.

[0009] As a further embodiment of this utility model: a heating frame is fixedly connected to the top of the screening box, and ventilation nets are respectively installed on the top of both sides of the screening box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This waste magnet recycling screening device, by setting up insertion blocks, a sliding frame, and a mounting plate, aligns the insertion blocks on both sides of the placement box with the sliding frame, then moves the mounting plate. The mounting plate drives the insertion blocks to insert into the sliding frame, causing the placement box to place the magnets inside the screening box. As the mounting plate continues to move, it causes the locking seat to engage with the insertion block, thus fixing the mounting plate and the placement box. The motor drives the cam to rotate via the rotating rod, causing the cam to press the fixing plate upward. The fixing plate causes the springs on the upper and lower sides to deform, and the spring force causes the placement box to shake, screening the magnets. After screening, pressing the insertion block releases the engagement between the insertion block and the locking seat, making it easy to remove the placement box and magnets, thus improving the convenience of the device.

[0012] 2. This waste magnet recycling screening device, by setting up a fan, hose, air outlet frame and electric telescopic rod, allows the fan to drive air downward through the hose to the air outlet frame, so that the air can flow through the air outlet frame to the heating frame. At the same time, the electric telescopic rod drives the heating frame to move, so that the heating frame and the air can fully contact the heating frame. After the air is heated by the heating frame, it comes into contact with the magnet, thereby achieving the demagnetization treatment of the magnet, thereby reducing the adsorption of magnets and impurities. It is convenient to use the shaking of the placement box to drive the magnet and impurities to be screened. The hot air can be flowed back into the hose through the fan to realize the recycling of heat. Attached Figure Description

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a screening device for recycling waste magnets, including a screening box 1, an installation frame 20 fixedly connected to the top of the screening box 1, and an electric telescopic rod 21 fixedly connected inside the installation frame 20. By setting the electric telescopic rod 21, the electric telescopic rod 21 drives the air outlet frame 19 to move, so that the air outlet frame 19 can guide the air, thereby allowing the air to fully contact the magnets on the inner wall of the placement box 8.

[0019] A blower 17 is fixedly connected to the side of the screening box 1 away from the collection drawer 11. The blower 17 is connected to the inside of the screening box 1. A flexible hose 18 is fixedly connected to the top of the blower 17. The end of the flexible hose 18 away from the blower 17 passes through the mounting frame 20 and is installed with an air outlet frame 19. The air outlet frame 19 is fixedly connected to the electric telescopic rod 21. By setting the flexible hose 18, the blower 17 can drive air into the flexible hose 18, thereby allowing the flexible hose 18 to guide the air and allow the air to flow into the air outlet frame 19, thereby realizing the recycling of the air inside the screening box 1.

[0020] A heating frame 22 is fixedly connected to the top of the screening box 1. Ventilation nets 23 are installed on the top of both sides of the screening box 1. By setting the ventilation nets 23, the ventilation nets 23 can ensure the normal flow of air between the inside of the screening box 1 and the outside air, so that the fan 17 can stably drive the flow of air inside the screening box 1.

[0021] A motor 14 is fixedly connected to one side of the screening box 1. The motor 14 has a rotating rod 15 installed through its output shaft. The rotating rod 15 is rotatably connected to the inner wall of the screening box 1 through a bearing. Cams 16 are symmetrically fixedly connected to both ends of the rotating rod 15 inside the screening box 1. The cams 16 are in close contact with the fixed plate 4. By installing the motor 14, the motor 14 drives the rotating rod 15 to rotate through its output shaft, so that the rotating rod 15 can drive the cams 16 to squeeze the fixed plate 4. This causes the fixed plate 4 to drive the sliding frame 5 and the placement box 8 to vibrate inside the fixed frame 2, thereby achieving the screening of magnets and impurities.

[0022] A fixed frame 2 is fixedly connected to the middle position inside the screening box 1. Multiple sliding rods 3 are slidably connected through both sides of the fixed frame 2. The sliding rods 3 are in groups of three. By setting the sliding rods 3, the sliding rods 3 can move together with the sliding frame 5, so that the sliding rods 3 can move inside the fixed frame 2. The fixed frame 2 can limit the movement of the sliding rods 3, so that the movement of the sliding rods 3 and the sliding frame 5 is more stable.

[0023] One end of each set of sliding rods 3 passes through the fixed frame 2 and is fixedly connected to the fixed plate 4. The ends of the two sets of sliding rods 3 away from the fixed plate 4 are fixedly connected to the sliding frame 5, and the sliding frame 5 slides tightly against the two sides inside the fixed frame 2. A spring 6 is sleeved on the surface of each sliding rod 3 between the sliding frame 5 and the inner wall of the fixed frame 2. By setting the spring 6, when the sliding frame 5 moves, it drives the spring 6 on the upper and lower sides to deform, so that the spring 6 generates relative elastic force to drive the sliding frame 5 to shake, thereby making the sliding frame 5 drive the screening box 1 to shake together, which facilitates the screening of magnets and impurities.

[0024] A sliding block 7 is slidably connected through the inner wall of the sliding frame 5. A placement box 8 is fixedly connected between two insertion blocks 7. A screening screen 9 is fixedly connected to the bottom of the placement box 8. An installation plate 10 is slidably connected to one side of the placement box 8. A collection drawer 11 is slidably connected through the bottom of the screening box 1. A snap-fit ​​seat 12 is fixedly connected to the top of one side of the installation plate 10. An insertion seat 13 is fixedly connected to the top of the snap-fit ​​seat 12 of the screening box 1. The insertion seat 13 snaps into the snap-fit ​​seat 12. By setting up the collection drawer 11, the collection drawer 11 can collect the impurities that fall during screening, thereby facilitating the unified treatment of the impurities inside the collection drawer 11 and improving the ease of use of the device.

[0025] The working principle of this utility model is as follows:

[0026] Place the magnet inside the placement box 8. Align the insertion blocks 7 on both sides of the placement box 8 with the sliding frame 5. Move the mounting plate 10, causing it to move the placement box 8. The placement box 8 then inserts the insertion blocks 7 into the sliding frame 5, thus placing the magnet inside the screening box 1. As the mounting plate 10 moves, it causes the snap-fit ​​seat 12 to snap into the insertion seat 13, securing the placement box 8 inside the screening box 1. Simultaneously, start the blower 17 and motor 14. The blower 17 draws air into the hose 18, which guides the air flow towards the outlet frame 19. At the same time, the electric telescopic rod 21 pushes the outlet frame 19 within the mounting frame 20. The air outlet frame 19 is activated so that the air discharged from the air outlet frame 19 can fully contact the heating frame 22. The air heated by the heating frame 22 flows to the magnet to demagnetize it. Then, the motor 14 drives the rotating rod 15 to rotate through the output shaft. The rotating rod 15 drives the fixed plate 4 to move upward through the cam 16. The fixed plate 4 simultaneously drives the sliding frame 5 and the sliding rod 3 to move. As the sliding frame 5 drives the spring 6 to deform, it generates a relative elastic force. This causes the spring 6 to drive the sliding frame 5 and the placement box 8 to shake. This allows the screening screen 9 at the bottom of the placement box 8 to screen the magnet. Impurities on the surface of the magnet pass through the screening screen 9 and fall into the collection drawer 11, completing the screening process of the magnet and impurities.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
