Description

Technical Field

[0001] This utility model relates to the field of solid waste recycling technology, and more specifically, to a screening device for recycling mining solid waste. Background Technology

[0002] Screening devices for mining solid waste recycling are highly efficient solid waste treatment equipment. They separate mixed mining solid waste according to size through physical screening methods, thereby improving the efficiency of subsequent processing. These devices typically utilize vibration or rotation to force materials through screens of different aperture sizes, achieving efficient separation and classification. Existing screening devices are generally of a single, integrated structure, making it difficult for workers to disassemble the screen plates and supports. This prevents workers from changing screen plates with different aperture diameters according to screening needs, reducing the accuracy and efficiency of screening. Utility Model Content

[0003] The main purpose of this utility model is to provide a screening device for mining solid waste recycling, which can effectively solve the problem that the screening devices in the background technology are generally of an integral structure, and the screen plate and the support are not easy to be disassembled by the workers, which makes it impossible for the workers to change the screen plate with different screen hole diameters according to the screening needs, thus reducing the accuracy and efficiency of screening.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A screening device for recycling solid waste in mining includes a material box. A horizontal shaft is rotatably installed between the two sides of the inner wall of the material box. Several brackets are fixedly fitted on the shaft of the horizontal shaft. A rotating frame is fixedly installed at the outer end of each bracket. Several slots are opened on one side surface of the rotating frame. Two limiting slots are opened on the two sides of the inner wall of each slot. A filter plate is slidably arranged in adjacent limiting slots.

[0006] Two positioning rods are fixedly installed on one side of the upper surface of each filter plate. A support plate is fixedly installed on the upper end of adjacent positioning rods. A connecting rod is fixedly installed on one side of each support plate. A slot is opened on one side surface of each connecting rod. The rotating frame is equipped with a limiting component for limiting movement.

[0007] Preferably, the limiting component includes several mounting plates, each of which is fixedly mounted on one side of the rotating frame. Each mounting plate has a mounting groove through one side surface, and two mounting blocks are slidably disposed in each mounting groove. A right-angle plate is fixedly mounted on one side of each mounting block, and each right-angle plate is respectively inserted into a corresponding slot.

[0008] Preferably, a bidirectional lead screw is rotatably installed between the two sides of the inner wall of each mounting groove, and adjacent mounting blocks are respectively threaded onto the two sides of the corresponding bidirectional lead screw.

[0009] Preferably, a vertical rod is rotatably mounted through the top of each mounting slot, a rotating wheel is fixedly mounted on the upper end of each vertical rod, and a first bevel gear is fixedly mounted on the lower end of each vertical rod;

[0010] Each of the bidirectional lead screws is fitted with a second bevel gear in the middle of its shaft, and each second bevel gear meshes with a corresponding first bevel gear.

[0011] Preferably, each mounting plate has a shield fixedly installed on both sides, and each connecting rod passes through the corresponding shield.

[0012] Preferably, each of the rollers has a limit bolt threaded through its upper surface.

[0013] Preferably, one end of the horizontal shaft passes through the material box and is fitted with a first gear, and a motor is fixedly installed on one side of the material box by a fixing frame. The output shaft of the motor passes through the fixing frame and is fitted with a second gear, which meshes with the first gear.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The staff put the material into the space formed by each filter plate and the rotating support frame. Then the staff controls the horizontal shaft to rotate, so that the filter plate rotates and screens the mining solid waste.

The rotating double-headed screw drives the adjacent mounting block and right-angle plate to move by screwing in the thread, so that the right-angle plate is disengaged from the corresponding slot. Then the staff moves the filter plate to disassemble and replace the filter plate, which improves the filtration efficiency and accuracy. Attached Figure Description

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-5 As shown, a screening device for recycling solid waste in mining includes a material box 1. A horizontal shaft 2 is rotatably installed between the two sides of the inner wall of the material box 1. Several brackets 3 are fixedly mounted on the shaft of the horizontal shaft 2. A rotating frame 4 is fixedly installed at the outer end of each bracket 3. Several slots 5 are opened on one side surface of the rotating frame 4. Two limiting slots 6 are opened on the two sides of the inner wall of each slot 5. A filter plate 7 is slidably arranged in adjacent limiting slots 6.

[0024] Two positioning rods 8 are fixedly installed on one side of the upper surface of each filter plate 7. A support plate 9 is fixedly installed on the upper end of adjacent positioning rods 8. A connecting rod 10 is fixedly installed on one side of the support plate 9. A slot is opened on one side surface of each connecting rod 10. The rotating frame 4 is equipped with a limiting component 11 for limiting the position.

[0025] The limiting component 11 includes several mounting plates 1101. Each mounting plate 1101 is fixedly installed on one side of the rotating frame 4. Each mounting plate 1101 has a mounting groove 1102 through it on one side surface. Two mounting blocks 1103 are slidably arranged in each mounting groove 1102. A right-angle plate 1104 is fixedly installed on one side of each mounting block 1103. Each right-angle plate 1104 is inserted and engaged with a corresponding slot on one side.

[0026] A bidirectional lead screw 12 is rotatably installed between the two sides of the inner wall of each mounting slot 1102, and adjacent mounting blocks 1103 are threaded onto the two sides of the corresponding bidirectional lead screw 12.

[0027] Workers place materials into the space formed by each filter plate 7 and the rotating support frame 4. Then, workers control the horizontal shaft 2 to rotate, causing the filter plate 7 to rotate and screen the mining solid waste. When it is necessary to replace the filter plate 7 with a different specification according to the screening requirements, workers control the bidirectional screw 12 to rotate. The rotating bidirectional screw 12 drives the adjacent mounting block 1103 and right-angle plate 1104 to move by screwing in, so that the right-angle plate 1104 disengages from the corresponding slot. Then, workers move the filter plate 7 to disassemble and replace it, thereby improving the filtration efficiency and accuracy.

[0028] In another embodiment of this utility model, a vertical rod 13 is rotatably mounted through the top of each mounting groove 1102, a rotating wheel 14 is fixedly mounted on the upper end of each vertical rod 13, and a first bevel gear 15 is fixedly mounted on the lower end of each vertical rod 13.

[0029] Each bidirectional lead screw 12 has a second bevel gear 16 fitted in the middle of its shaft, and each second bevel gear 16 meshes with the corresponding first bevel gear 15.

[0030] The operator rotates the rotating wheel 14, which drives the first bevel gear 15 to rotate. Under the meshing action of the first bevel gear 15 and the second bevel gear 16, the bidirectional lead screw 12 rotates and drives the mounting block 1103 to move.

[0031] In another embodiment of this utility model, each mounting plate 1101 is fixedly installed with a shield 17 on both sides, and each connecting rod 10 passes through the corresponding shield 17.

[0032] By setting up the shield 17, dust from the surrounding area is prevented from adhering to the meshing point of the first bevel gear 15 and the second bevel gear 16 during the screening process, thus ensuring the stability of meshing.

[0033] In another embodiment of this utility model, a limit bolt 18 is provided through a thread on the upper surface of each rotating wheel 14.

[0034] By setting a limit bolt 18, the operator can tighten the limit bolt 18 so that one end of it is pressed against the mounting plate 1101, thereby fixing the position of the rotating wheel 14 and preventing it from shifting during the screening process.

[0035] In another embodiment of the present invention, one end of the horizontal shaft 2 passes through the material box 1 and is fitted with a first gear 19. A motor 21 is fixedly installed on one side of the material box 1 by a fixing frame 20. The output shaft end of the motor 21 passes through the fixing frame 20 and is fitted with a second gear 22. The second gear 22 meshes with the first gear 19.

[0036] The staff started the motor 21, which caused its output shaft to drive the second gear 22 to rotate. Under the meshing action of the second gear 22 and the first gear 19, the rotating frame 4 drove the filter plate 7 to rotate.

[0037] The working principle of a screening device for mining solid waste recycling:

[0038] In use, the staff puts the material into the space formed by each filter plate 7 and the rotating support 4. Then, the staff controls the horizontal shaft 2 to rotate, so that the filter plate 7 rotates and screens the mining solid waste. When it is necessary to replace the filter plate 7 with a different specification according to the screening requirements, the staff controls the double-headed screw 12 to rotate. The rotating double-headed screw 12 drives the adjacent mounting block 1103 and right-angle plate 1104 to move by screwing in, so that the right-angle plate 1104 disengages from the corresponding slot. Then, the staff moves the filter plate 7 to disassemble and replace the filter plate 7, which improves the filtration efficiency and accuracy.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
