Description

Technical Field

[0001] This utility model relates to the technical field of dismantling waste refrigerators, specifically to an eddy current separator for a waste refrigerator dismantling line. Background Technology

[0002] In the dismantling of used refrigerators, which contain both metals and non-metals, the internal foam is collected after crushing in the previous process. The non-metallic shell and internal metal parts are transported by an elevator to a vibrating machine, and then separated by an eddy current separator. The principle of the eddy current separator is that a high-frequency alternating magnetic field is generated at the magnetic drum. The conductor is induced by this magnetic field, and the magnetic field generated by the induced eddy current is opposite to the original magnetic field. The metal will jump out along the conveying direction due to the reaction force, achieving separation. During the material separation process, the conveyed non-ferrous metals are subjected to an additional magnetic force. Depending on the material's trajectory, the separating structure mainly serves to separate non-metallic and non-ferrous metal materials. The separating structure determines the recovery rate and purity of the non-ferrous metals, playing a crucial role.

[0003] Existing eddy current separators have poor distribution effects, which is not conducive to eddy current separation. In addition, the separation angle of the dividing plate is difficult to control and inconvenient to adjust.

[0004] A patent publication number CN222197338U, entitled "A Novel Eddy Current Separator," was found, specifically disclosing a novel eddy current separator. The separator includes a housing. On one side of the housing, from far to near, are arranged a non-ferrous metal collection trough and a non-metal collection trough. On the other side of the housing, a vibrating feeding structure is installed. Support plates and sliding inclined plates are respectively arranged on both sides of the top of the housing. The support plates are positioned closer to the vibrating feeding structure. The support plates and vibrating inclined plates are arranged in a "V" shape. A separating plate is installed between the non-ferrous metal collection trough and the non-metal collection trough, and the separating plate is biased towards the sliding inclined plate. A magnetic roller structure is provided on the lower side of the sliding inclined plate. Preferably, the vibrating feeding structure includes a support, which is positioned on the side of the housing away from the non-metal collection trough. A vibrating feeder is mounted on the support, and an excitation motor is installed at the bottom of the vibrating feeder. Several damping springs are provided between the vibrating feeder and the support.

[0005] Analysis of the publicly available materials shows that eddy current separation can be achieved, but the even distribution effect and the angle adjustment of the material distribution plate cannot be achieved. Utility Model Content

[0006] In view of this, the present invention provides an eddy current separator for a waste refrigerator dismantling line, which not only achieves the effect of material distribution, but also allows for quick and convenient adjustment of the angle of the separating plate.

A material leveling device, comprising a fixed plate mounted on a frame, an adjusting screw mounted on the fixed plate, a second fastening nut connected to the adjusting screw, a material feeding plate connected to the lower end of the adjusting screw, and a leather curtain mounted at the lower end of the material feeding plate; An angle adjustment device includes a bearing seat mounted on a frame, a rotating shaft connected to the bearing seat, a bracket connected to the rotating shaft, a material distribution plate connected to the bracket, an adjustment plate connected to the end of the rotating shaft, an arc-shaped hole provided on the adjustment plate, a fixing screw mounted on the frame, the fixing screw being disposed within and extending out of the arc-shaped hole, and a first fastening nut connected to the fixing screw.

[0008] Furthermore, a support plate is provided on the side of the fixing plate. The support plate is horizontally positioned and has holes. The adjusting screw is placed in the holes on the support plate and can move up and down. A second fastening nut is provided on both the upper and lower ends of the support plate.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figures 1 to 4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0018] like Figures 1 to 4 As shown: Example

[0019] An eddy current separator for a waste refrigerator dismantling line includes a frame 1, a conveyor belt 2 mounted on the frame 1, a motor 3 mounted on the frame 1, a sorting cylinder 8 connected to the motor 3, the conveyor belt 2 wound around the sorting cylinder 8, a vibrator 4 mounted on the frame 1, and a material leveling device. The material leveling device includes a fixing plate 17 mounted on the frame 1, an adjusting screw 20 mounted on the fixing plate 17, a second fastening nut 21 connected to the adjusting screw 20, and a material-pushing plate 18 connected to the lower end of the adjusting screw 20. A leather curtain 19 is provided at the lower end of the feeding plate 18; an angle adjustment device is provided, the angle adjustment device includes a bearing seat 9 provided on the frame 1, the bearing seat 9 is connected to a rotating shaft 10, the rotating shaft 10 is connected to a bracket 11, the bracket 11 is connected to a material distribution plate 12, the end of the rotating shaft 10 is connected to an adjustment plate 13, the adjustment plate 13 is provided with an arc-shaped hole 14, the frame 1 is provided with a fixing screw 24, the fixing screw 24 is located in the arc-shaped hole 14 and extends out of the arc-shaped hole 14, and the fixing screw 24 is connected to a first fastening nut 16.

[0020] In this embodiment, the frame 1 serves as a support, and a conveyor belt 2 is installed on the frame 1. The conveyor belt 2 is driven by rollers. A sorting cylinder 8 is set at the tail end of the conveyor belt 2. The sorting cylinder 8 is an eddy current magnetic roller. After passing through the sorting cylinder 8, metal materials and non-metal materials can move along different parabolic paths, thereby achieving different feeding paths.

[0021] On conveyor belt 2, the mixture after being fed by vibrator 4 is initially evenly distributed. However, after the material falls onto conveyor belt 2, it will collide and bounce, resulting in uneven mixing. By setting a material leveling device on frame 1, the material can be evenly spread, which facilitates the sorting in the next process.

[0022] In the sorting process, in order to improve the sorting efficiency and the purity of the sorting, the angle adjustment of the sorting plate 12 is very important. The adjustment plate 13 is fixed by setting a handle 15 on the adjustment plate 13, and by cooperating with the first fastening nut 16 and the fixing screw 24. Example

[0023] A support plate 25 is provided on the side of the fixed plate 17. The support plate 25 is horizontally arranged and has holes. The adjusting screw 20 is placed in the holes on the support plate 25 and can move up and down. The upper and lower ends of the support plate 25 are provided with second fastening nuts 21, which lock the position of the adjusting screw 20 on the support plate 25.

[0024] Unlike the above embodiments, in this embodiment, a support plate 25 is provided on the side of the fixing plate 17. The support plate 25 has a hole through which the adjusting screw 20 passes and can move up and down in the hole by external force. The adjusting screw 20 is fixed by the second fastening nut 21, thereby realizing the up and down adjustment of the feeding plate 18. Example

[0025] The lower end of the adjusting screw 20 is fixedly connected to the material feeding plate 18, and a rubber curtain 19 is installed at the lower end of the material feeding plate 18. A gap is left between the lower end of the curtain 19 and the upper surface of the conveyor belt 2.

[0026] Unlike the above embodiments, in this embodiment, the lower end of the material feeding plate 18 is a leather curtain 19, which is made of rubber and can evenly distribute the material. Example

[0027] The upper end face of the feeding plate 18 is provided with a guide rod 23, and a sleeve 22 is provided on one side of the fixing plate 17. The guide rod 23 is inserted into the sleeve 22 and can move in the sleeve 22.

[0028] Unlike the above embodiments, in this embodiment, the guide rod 23 is used to guide the adjustment plate 18 after adjusting its up and down position, so as to prevent the adjustment plate 13 from tilting. Example

[0029] The bracket 11 is a triangular iron structure, and the two ends of the material distribution plate 12 are fixed on the bracket 11. The material distribution plate 12 is a rubber plate, and the rotating shaft 10 is fixedly connected to the outer side of the bracket 11.

[0030] Unlike the above embodiments, in this embodiment, the bracket 11 is fixedly connected to the material distribution plate 12, and the material distribution plate 12 is a rubber plate to avoid interference from eddy currents. Example

[0031] The adjusting plate 13 has a fan-shaped structure and is vertically arranged. The adjusting plate 13 and the rotating shaft 10 are perpendicular to each other, and the center of the arc-shaped hole 14 coincides with the center of the adjusting plate 13.

[0032] Unlike the above embodiments, in this embodiment, the adjusting plate 13 has a fan-shaped structure, and the angle of the dispensing plate 12 can be adjusted by rotating the adjusting plate 13. Example

[0033] A handle 15 is provided on the outer side of the adjustment plate 13, and the adjustment plate 13 is rotated by the handle 15.

[0034] Unlike the above embodiments, in this embodiment, it is more convenient to operate the rotation of the adjustment plate 13 by the handle 15 when adjusting the angle of the material distribution plate 12.

[0035] The working method (or working principle) of this utility model: In operation, the fixed plate 17 is installed on the frame 1. After crushing the waste refrigerator and processing the foam, the mixture is conveyed by the elevator to the vibrator 4. The vibrator 4 vibrates the material, achieving initial even distribution. The material then falls onto the conveyor belt 2 and passes through the material-distributing plate 18 installed on the fixed plate 17. The curtain 19 below the material-distributing plate 18 ensures precise even distribution of the mixture. The evenly distributed mixture is then transported to the sorting cylinder 8 by the conveyor belt 2. Non-metallic fragments undergo parabolic motion at the horizontal speed of the conveyor belt 2. Due to the material-distributing plate 12, the non-metallic material falls directly into the non-metallic outlet 7 below the material-distributing plate 12. Metallic fragments undergo parabolic motion outward under magnetic force. Due to the angle adjustment device of the material-distributing plate 12, the metallic material falls onto the material-distributing plate 12 and enters the metallic outlet along the material-distributing plate 12.

[0036] In this utility model, unless otherwise explicitly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
