Description

Technical Field

[0001] This utility model relates to the technical field of waste aluminum recycling, and in particular to a screening device for waste aluminum recycling. Background Technology

[0002] Waste aluminum is an important resource, and its recycling and reuse is an extremely beneficial endeavor. Waste aluminum recycling enables the effective use of resources and saves a significant amount of energy. Currently, existing waste aluminum materials often contain many iron impurities. In the waste aluminum recycling process, the recycled waste aluminum needs to be crushed into small pieces, and then the iron impurities contained in the waste aluminum need to be separated through a screening device. Finally, the pure waste aluminum blocks are sent to a furnace for melting and reuse.

[0003] For example, Chinese utility model patent CN202420237047.9 describes a screening device for recycling waste aluminum. When waste aluminum passes through a sorting rake, the piled waste aluminum can be spread out, increasing the contact area between the waste aluminum and the magnetic adsorption device. Then, the iron impurities in the waste aluminum are automatically adsorbed onto the surface of the conveyor belt by the strong magnet. The conveyor belt then transports the adsorbed iron impurities to one side until they reach the removal plate. At this point, the iron impurities no longer have an adsorption force between them and the strong magnet, and they automatically fall into the collection box. The removal plate effectively scrapes off the iron impurities from the surface of the conveyor belt, improving the cleaning and collection effect. However, the position of the sorting rake is fixed, resulting in poor spreading effect for waste aluminum that is stuck together or bridged. Furthermore, the waste aluminum is easily stuck between the rake teeth, causing jamming and hindering the normal transport of materials. Summary of the Invention

[0004] The purpose of this invention is to provide a screening device for recycling waste aluminum, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is: A screening device for recycling waste aluminum includes a screening assembly. The screening assembly includes: a first support frame disposed on the top of a conveyor belt; a separation assembly disposed on the first support frame; and a dispersing assembly disposed on one side of the first support frame. The dispersing assembly includes: a second support frame disposed on one side of the first support frame; a motor disposed and fixed on one side of the second support frame; a reciprocating screw disposed at the output end of the motor and passing through the second support frame; a movable frame sleeved on the outside of the reciprocating screw; a limiting member disposed between the movable frame and the second support frame; and rake teeth symmetrically disposed on the movable frame and located above the conveyor belt.

[0006] Optionally, the movable frame is provided with an adjustment groove that matches the rake teeth, a fixing bolt is provided on one side of the movable frame and passes through the adjustment groove and the rake teeth, and a positioning hole is provided on one side of the movable frame that matches the fixing bolt.

[0007] Optionally, a limiting plate is provided on the top of the rake teeth.

[0008] Optionally, the limiting member includes: a first slider disposed on one side of the movable frame, and a first groove that cooperates with the first slider disposed on the inner side of the second support frame.

[0009] Optionally, a threaded rod is provided on one side of the first support frame to cooperate with the second support frame and to pass through the second support frame.

[0010] Optionally, a second slider is provided on the outer side of the second support frame, and a second groove is provided on the side wall of the first support frame to cooperate with the second slider.

[0011] Optionally, a locking nut is fitted on the outer side of the threaded rod and is located on top of the support plate of the first support frame side wall.

[0012] Optionally, an anti-slip pad is provided between the locking nut and the top of the side wall support plate of the first support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The reciprocating screw is driven by a motor to rotate. The rotating reciprocating screw, together with the limiting component, drives the moving frame to move back and forth. The moving frame pushes the rake teeth to actively break up and spread the scrap aluminum material that is stuck or bridged together, which increases the spreading effect of scrap aluminum material and avoids scrap aluminum material getting stuck at the rake teeth and hindering the normal material conveying.

They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] Given that the current technology uses a fixed position for the material distribution rake, the spreading effect on scrap aluminum that is stuck together or bridged is poor, and the scrap aluminum is easily stuck between the rake teeth, causing material jamming and hindering the normal conveying of materials.

[0020] like Figure 1-3As shown, this utility model embodiment provides a screening device for recycling waste aluminum, including a screening component 1. The screening component 1 includes: a first support frame 12 disposed on the top of a conveyor belt 11; a separation component 13 disposed on the first support frame 12; and a dispersing component 2 disposed on one side of the first support frame 12. The dispersing component 2 includes: a second support frame 21 disposed on one side of the first support frame 12; a motor 22 disposed and fixed on one side of the second support frame 21; a reciprocating screw 23 disposed at the output end of the motor 22 and passing through the second support frame 21; a movable frame 231 sleeved on the outside of the reciprocating screw 23; a limiting member 24 disposed between the movable frame 231 and the second support frame 21; and rake teeth 25 symmetrically disposed on the movable frame 231 and located above the conveyor belt 11.

[0021] In use, the crushed waste aluminum is poured onto the conveyor belt 11 and transported to the next process via the conveyor belt 11. When the waste aluminum passes the rake teeth 25, the motor 22 drives the reciprocating screw 23 to rotate. The rotating reciprocating screw 23, together with the limiting component 24, drives the moving frame 231 to move back and forth. The moving frame 231 pushes the rake teeth 25 to actively break up and spread the waste aluminum that is stuck or bridged together, which increases the spreading effect of the waste aluminum and avoids the waste aluminum from getting stuck at the rake teeth 25 and hindering the normal transport of materials. Then, the iron impurities in the waste aluminum are separated and screened by the separation component 13.

[0022] Specifically, the separation component 13 is the same as the prior art (CN202420237047.9). It uses the magnetism of a strong magnet to automatically attract iron impurities in waste aluminum to the surface of the conveyor belt during operation. The conveyor belt then transports the iron impurities adsorbed on the surface to one side until they reach the position of the removal plate. There is no longer any attraction between the iron impurities and the strong magnet, and the iron impurities automatically fall into the receiving box. The removal plate effectively scrapes off the iron impurities from the surface of the conveyor belt.

[0023] Specifically, the reciprocating lead screw 23 and the moving frame 231 are connected by threads.

[0024] Furthermore, the movable frame 231 is provided with an adjustment groove 26 that matches the rake teeth 25. A fixing bolt 261 is provided on one side of the movable frame 231 and passes through the adjustment groove 26 and the rake teeth 25. A positioning hole 262 that matches the fixing bolt 261 is provided on one side of the movable frame 231. By pushing the rake teeth 25 to move in the adjustment groove 26, and by fixing the rake teeth 25 with the fixing bolt 261 passing through the corresponding positioning hole 262, the spacing between the rake teeth 25 can be adjusted so that the rake teeth 25 can be used for scrap aluminum of different sizes.

[0025] Furthermore, a limit plate 251 is provided on the top of the rake tooth 25 to limit the up and down movement of the rake tooth 25 and prevent the rake tooth 25 from dislodging from the adjustment groove 26 during adjustment.

[0026] Furthermore, the limiting member 24 includes: a first slider 241 disposed on one side of the movable frame 231, and a first sliding groove 242 that cooperates with the first slider 241 on the inner side of the second support frame 21, so that the movable frame 231 and the second support frame 21 are slidably connected, preventing the movable frame 231 from rotating with the reciprocating screw 23.

[0027] Furthermore, a threaded rod 27 is provided on one side of the first support frame 12 to cooperate with the second support frame 21 and to pass through the second support frame 21. By rotating the threaded rod 27, the rotating threaded rod 27 pushes the second support frame 21 to move up and down, thereby adjusting the distance between the rake teeth 25 and the conveyor belt 11, so that the rake teeth 25 can be used for scrap aluminum with different stacking thicknesses.

[0028] Specifically, the threaded rod 27 is rotatably connected to the first support frame 12.

[0029] Specifically, the threaded rod 27 and the second support frame 21 are connected by threads.

[0030] Furthermore, a second slider 28 is provided on the outer side of the second support frame 21, and a second sliding groove 281 is provided on the side wall of the first support frame 12 to cooperate with the second slider 28, so that the second support frame 21 and the first support frame 12 are slidably connected, which increases the stability of the threaded rod 27 pushing the second support frame 21 to move up and down.

[0031] Furthermore, a locking nut 29 is fitted on the outer side of the threaded rod 27 and is located on the top of the side wall support plate of the first support frame 12. After the height of the second support frame 21 is adjusted, by rotating the locking nut 29, the locking nut 29 moves downward through the threaded rod 27 to press the top of the side wall support plate of the first support frame 12, thereby pressing and locking the threaded rod 27, which increases the stability of the second support frame 21 after adjustment.

[0032] Furthermore, an anti-slip pad 291 is provided between the locking nut 29 and the top of the side wall support plate of the first support frame 12, which increases the anti-slip properties of the locking nut 29 in pressing and locking the threaded rod 27.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
