[0002] An electrostatic separator is a method of separation that utilizes the electrical property differences of each component in a solid material in a high-voltage electric field, and is applicable to the separation of materials with different electrical conductivity of each component. The charging method of the material in the electrostatic separator is direct conduction charging. The material directly contacts the conduction electrode. The material with good electrical conductivity will obtain the same charge as the electrode polarity and be repelled, while the material with poor electrical conductivity or non-conductor contacts the charged roller and is polarized, generating opposite bound charges at one end close to the roller and being attracted by the roller, thus realizing the separation of materials with different electrical properties.

[0003] Chinese Patent with Publication No. CN214160052U discloses an electrostatic separator. By performing two-stage electrostatic separation on the material and separating the mixture after the first electrostatic separation again by electrostatic separation, it is not necessary to put the material after the initial electrostatic separation into the equipment again, improving the electrostatic separation effect and quality. At the same time, the electric plate, the material guide plate and the partition plate inside the housing can be adjusted in position inside the housing by turning the bolts, which is convenient for corresponding adjustment according to different materials.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] To solve the problem that it is difficult to simply adjust the position of the electrode plate, and thus it is impossible to select a suitable position of the electrode plate according to the content of different materials in the solid mixture, please refer to Figures 1-4, an embodiment provided by the present utility model: an electrostatic aluminum foam separator, which includes a feeding bin 2 and a frame 5, and also includes a charge output mechanism 8. A feeding roller 201 is arranged inside the feeding bin 2. A transmission wheel 202 is arranged on one side of the feeding roller 201. The transmission wheel 202 is externally connected to a motor. The feeding roller 201 and the first transmission wheel 202 are connected by a shaft. A hopper 1 is arranged above the feeding bin 2. An observation port 101 is arranged on the side of the hopper 1. A first sorting roller 7 is arranged inside the frame 5. A guide plate 402 is arranged below the first sorting roller 7. A first cleaning roller 6 is arranged on one side of the first sorting roller 7. A second sorting roller 701 is arranged below the first sorting roller 7. A second cleaning roller 601 is arranged on one side of the second sorting roller 701. A side discharge port 3 is arranged below the second sorting roller 701. A front baffle 401 is arranged on one side of the guide plate 402. A front discharge port 4 is arranged below the guide plate 402.

[0024] A square channel is arranged at the contact surface between the feeding bin 2 and the hopper 1. The lower part of the feeding bin 2 is in an open state. A number of rakes for grasping materials are arranged on the surface of the feeding roller 201. The feeding roller 201 rotates continuously inside. The rakes on its surface grab the solid mixture falling from the hopper and send it to the first sorting roller 7 below, preventing the solid mixture from getting stuck inside the hopper 1 or the feeding bin 2. The staff can judge whether there is a blockage by observing the observation port 101 on the side of the hopper 1 and the amount of material discharged from the discharge port, further improving the sorting efficiency.

[0025] Side baffles 301 are arranged below both the first cleaning roller 6 and the second cleaning roller 601. Brush hairs are arranged on the surfaces of the first cleaning roller 6 and the second cleaning roller 601. The brush hairs contact the surface of the sorting roller and can sweep off the materials bound on the sorting roller. The swept-off materials finally slide out from the side discharge port 3. Rollers are arranged at one end of both the first cleaning roller 6 and the second cleaning roller 601. Rollers are arranged at one end of both the first sorting roller 7 and the second sorting roller 701. The rollers are externally connected to an engine. Starting the external engine can drive the rollers to rotate.

[0026] The first sorting roller 7 and the second sorting roller 701 cooperate with each other, and can perform two sorts on the solid mixture, reducing the situation that the materials after the initial electrostatic sorting need to be put into the equipment again, improving the efficiency of electrostatic sorting. At the same time, on the basis of the traditional structure, the sorting rollers are thickened, further improving the sorting effect.

[0027] The charged output mechanism 8 includes an electrode plate 801, a gear 802, a gear shaft 803, a fixed rod 804, a turntable 805, a positioning plate 806 and a fixed seat 807. The turntable 805 is installed at one end of the gear shaft 803. The electrode plates 801 are installed at both ends of the fixed rod 804. The gears 802 are installed at both ends of the gear shaft 803. The positioning plate 806 and the fixed seat 807 are fixed to the frame 5 by screws. A number of wires are arranged between two opposing electrode plates 801. The electrode plate 801 is of an arc-shaped structure. A rack is provided on the convex surface of the electrode plate 801. The rack meshes with the gear 802. When it is necessary to adjust the position of the electrode plate 801, the turntable 805 is rotated to drive the gear 802 to rotate, thereby driving the electrode plate 801 to move quickly within a certain range, so as to change the throwing point of the material, and further improving the ability to separate solid mixtures.

[0028] Working principle: The solid mixture in the hopper 1 falls onto the first sorting roller 7. The materials with poor conductivity or non-conductors in the solid mixture come into contact with the first sorting roller 7 and are polarized, so that they are bound to the surface of the first sorting roller 7. The materials with good conductivity are repelled, and at the same time are attracted by the charged output mechanism 8 and fall out through the front discharge port 4 under the action of gravity. After the initial sorting, the solid mixture bound to the first sorting roller 7 is swept off by the first cleaning roller 6 and directly falls onto the surface of the second sorting roller 701, so as to perform secondary sorting. Finally, the materials with poor conductivity slide out through the side discharge port 3, and the materials with good conductivity slide out through the front discharge port 4.

[0029] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
