[0002] An electrostatic separator is a device that uses the principle of electrostatics to separate materials. It can be used to separate materials of different qualities, such as metal powder and waste plastic. The vibrating screen for spreading materials in an electrostatic separator is a device that combines the principles of electrostatic separation and vibration screening, and can be used for more precise screening and processing of materials.

[0003] Chinese utility model patent CN217664723U discloses an electrostatic separation and screening device, including a frame, a vibrating screen, a material leveling guide plate, and an electrostatic separator. The vibrating screen is arranged parallel to the frame, and the material leveling guide plate is arranged horizontally on the vibrating screen to level the material entering the vibrating screen, making the material evenly spread on the vibrating screen. The electrostatic separator is arranged parallel to the top of the vibrating screen. This technical solution uses the electrostatic separator to screen lighter impurities in the vibrating screen, separating heavy and light impurities in the material. The material leveling guide plate on the vibrating screen allows the material to be evenly spread on the vibrating screen. Heavy impurities in the material pass through the screen mesh and enter the screening and separation chamber below the screen mesh under the action of the vibrating screen. After screening, the screened material may remain in the vibrating separation chamber, affecting the collection of the screened material by the workers. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, a vibrating screen for spreading materials in an electrostatic separator includes a mounting frame 1, a vibrating frame 2, and an electrostatic separator 3 disposed above the vibrating frame 2. The electrostatic separator 3 is fixed to the mounting frame 1 by bolts. The right end of the vibrating frame 2 extends out of the mounting frame 1. A motor mounting frame 1 is welded to the lower side of the vibrating frame 2. A vibrating motor 6 is fixed to the lower side of the motor mounting frame 1 by bolts. Four springs are arranged in a rectangular array on the lower side of the vibrating frame 2. The upper and lower ends of the springs are respectively connected to spring connecting blocks fixed to the lower side of the vibrating frame 2 and the mounting frame 1. A screen plate 21 with multiple vertically opened screen holes is fixed inside the vibrating frame 2 by bolts. The above content is the prior art of the electrostatic separation and screening device with application number CN202221350664.7. The specific connection relationship and working principle are the same as the prior art. 21 The inner side of the vibrating frame 2 is divided into a vibrating chamber 4 and a vibrating separation chamber 5. The vibrating frame 2 and the screen plate 21 are inclined from right to left. The vibrating chamber 4 is located above the screen plate 21, and the vibrating separation chamber 5 is located below the screen plate 21. The vibrating chamber 4 and the vibrating separation chamber 5 are connected through the screen holes of the screen plate 21. The left side of the vibrating separation chamber 5 and the vibrating chamber 4 are respectively connected to the first discharge cylinder 8 and the second discharge cylinder 9. Two collection frames 10 are provided on the left side of the mounting frame 1. The upper part of the two collection frames 10 is respectively connected to the first receiving pipe 11 and the second receiving pipe 12. The first receiving pipe 11 and the second receiving pipe 12 are located directly below the first discharge cylinder 8 and the second discharge cylinder 9, respectively. A storage frame 13 is inserted in each of the two collection frames 10. A pushing component is provided in the vibrating frame 2 for pushing out the residual material in the vibrating chamber 4 and the vibrating separation chamber 5.

[0019] In operation, the staff pours the material into the vibrating chamber 4 using the material conveying device 7. Under the action of the electrostatic separator 3, light impurities and other materials are separated. Then, under the action of the vibrating motor 6, different materials are separated. The smaller diameter materials enter the vibrating separation chamber 5 through the sieve holes on the sieve plate 21. The material after screening in the vibrating chamber 4 enters the first receiving pipe 11 through the first discharge cylinder 8 and moves along the first receiving pipe 11 to the storage frame 13 on the left. The impurities in the vibrating separation chamber 5 are sent to the second... The material enters the second receiving pipe 12 from the second discharge cylinder 9 and then enters the storage box 13 on the right. After that, the staff will start the pushing component to push the material and impurities in the vibration separation chamber 5 and vibration cavity 4 to the second discharge cylinder 9 and the first discharge cylinder 8, and then enter the storage box 13 in the collection box 10 through the first discharge cylinder 8 and the second discharge cylinder 9. After that, the staff can pull the storage box 13 out of the collection box 10 and collect the screened material, which is convenient for the staff to collect the screened material and improves the work efficiency of the staff.

[0020] In this embodiment, the lower side of the vibration separation chamber 5 is inclined, and it gets lower from right to left.

[0021] In this embodiment, the feeding assembly includes two sets of lead screws 14, which are rotatably connected to the vibration separation chamber 5 and the vibration cavity 4, respectively. Two push plates 15 are threaded onto each of the two sets of lead screws 14. The right ends of the two lead screws 14 located in the vibration cavity 4 penetrate the right side wall of the vibration frame 2 and are respectively fixed to the output shafts of two drive motors 16. Both drive motors 16 are fixed to the right side wall of the vibration frame 2. Gears 17 are fixed to the right ends of multiple lead screws 14. Two gears 17 located at the front of the vibration frame 2 and two gears 17 located at the rear of the vibration frame 2 are respectively connected by two toothed belts 18. The lower sides of the two push plates 15 are respectively connected to the upper surface of the screen plate 21. On the side and the lower side of the vibration separation chamber 5, the operator controls the lead screw 14 to rotate via the drive motor 16. The lead screw 14 drives another lead screw 14 to rotate through the cooperation of the gear 17 and the toothed belt 18. The two lead screws 14 located above the screen plate 21 drive the push plate 15 located above the screen plate 21 to move, and the two lead screws 14 located below the screen plate 21 drive the push plate 15 located below the screen plate 21 to move. This causes the push plate 15 to move from right to left on the screen plate 21 and the lower side wall of the vibration separation chamber 5, pushing the material in the vibration separation chamber 5 and on the screen plate 21 into the first discharge pipe and the second discharge pipe, thereby improving the efficiency of material collection in the vibration separation chamber 5.

[0022] In this embodiment, a handle 19 is welded to the front side of the storage box 13. When in use, the staff can pull the storage box 13 out of the collection box 10 through the handle 19, which improves the convenience of the staff when collecting materials in the storage box 13.

[0023] In this embodiment, a feeding hopper 20 is provided on the upper side of the material conveying device 7. During use, the staff can pour the material into the vibration chamber 4 through the feeding hopper 20, which improves the feeding efficiency of the staff.
