Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, specifically to a recycling device and method for the resource-based screening and utilization of mining solid waste. Background Technology

[0002] Solid waste generated from the coal mining industry may contain a certain proportion of valuable coal and other mineral materials. By screening and classifying mining solid waste such as coal gangue and slag, recyclable resources can be effectively extracted and utilized, achieving resource reuse and recycling. This not only effectively reduces resource consumption but also reduces pressure on the natural environment. This is of great significance for promoting sustainable development and green mining. Screening for resource recovery from mining solid waste such as coal gangue and slag typically requires sorting according to particle size. This is because mining solid waste such as coal gangue and slag may contain particles of different sizes, and these particles may have different uses and values ​​in subsequent treatment and utilization; therefore, screening is necessary to separate particles of different sizes.

[0003] In existing technologies, when mining solid wastes such as coal gangue and slag are piled together for screening, it is difficult to prevent the solid wastes from being squeezed together and stuck at the filter opening, which affects the normal screening of the equipment. In addition, existing technologies make it difficult to separate and collect different coal gangue, slag and other mining solid waste particles after screening, which causes inconvenience to the subsequent treatment and effective utilization of solid waste. Therefore, it is necessary to propose a recycling device and method for the resource-based screening and utilization of mining solid waste. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the prior art where, when mining solid wastes such as coal gangue and slag are piled together for screening, it is difficult to prevent the solid wastes from being squeezed together and stuck at the filter opening, which affects the normal screening of the equipment. In addition, the prior art makes it difficult to separate and collect different coal gangue, slag and other mining solid waste particles after screening, which causes inconvenience to the subsequent treatment and effective utilization of solid waste. Therefore, this invention proposes a recycling device and method for the resource-based screening and utilization of mining solid waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The vibration mechanism includes a first rotating shaft disposed inside the screening box. A first connecting block is fixedly connected to the outside of the first rotating shaft. A second connecting block is fixedly connected to the outside of the first connecting block. A third connecting block is rotatably connected to the outside of the second connecting block. A support block is fixedly connected to the side of the third connecting block away from the second connecting block.

[0007] The support block is provided with a retractable mechanism. The retractable mechanism includes a fourth connecting block disposed outside the support block. A third rotating shaft is rotatably connected to the outside of the fourth connecting block. A rotating block is fixedly connected to the outside of the third rotating shaft. A first connecting rod is fixedly connected to the outside of the rotating block. A second rotating shaft is rotatably connected to the outside of the fourth connecting block. The second rotating shaft and the rotating block are fixedly connected.

[0008] The fourth connecting block is configured in multiple ways, one of which is fixedly connected to the support block, while the others are slidably connected to the support block. The rotating blocks are configured in pairs, and adjacent rotating blocks are fixedly connected by the first connecting rod.

[0009] The above technical solution further includes:

[0010] A second motor is fixedly installed on the outside of the fourth connecting block. The output end of the second motor is fixedly connected to the second rotating shaft. A third gear is fixedly connected to the outside of the second rotating shaft. A fourth gear is meshed with the outside of the third gear. The fourth gear is fixedly connected to the third rotating shaft.

[0011] The third and fourth gears are configured in multiple ways to facilitate the rotation of the second and third rotating shafts.

[0012] The support block is slidably connected to a telescopic rod, and the side of the telescopic rod away from the support block is fixedly connected to the fourth connecting block. The screening box has a sliding groove inside, and the sliding groove is slidably connected to a first connecting plate, which is fixedly connected to the support block.

[0013] The telescopic rods are arranged in multiple ways to ensure stability when the fourth connecting block is extended or retracted.

[0014] A first motor is fixedly installed on the outside of the screening box. The output end of the first motor is fixedly connected to the first rotating shaft. A first gear is fixedly connected to the outside of the first rotating shaft.

[0015] The first rotating shaft facilitates the rotation of the first gear.

[0016] The first gear is externally meshed with a second gear, the second gear is externally fixedly connected with a threaded rod, and the threaded rod is externally threadedly connected with a first slider;

[0017] The threaded rod facilitates the movement of the first slider.

[0018] A third connecting rod is fixedly connected to the outside of the first slider, and a second connecting plate is fixedly connected to the side of the third connecting rod away from the first slider. A cleaning column is fixedly connected to the outside of the second connecting plate.

[0026] Step 2: The rotation of the first rotating shaft drives the second connecting block to move up and down continuously through the first connecting block, and then drives the externally fixed support block to vibrate continuously through the third connecting block. This helps to prevent solid waste from squeezing each other and getting stuck at the filter opening, thereby improving the screening efficiency of the equipment.

[0027] Step 3: After screening, the receiving and discharging mechanism retracts, causing the third and second rotating shafts to rotate. This facilitates the rotation of the externally fixed rotating block, allowing larger particles of impurities to fall to the bottom of the screening box for easy collection.

[0028] Step 4: After collection is complete, restore the collection and release mechanism to its original position to facilitate the next screening and recycling. Repeat the above steps.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. In this invention, when in use, by starting the first motor, the first rotating shaft set at the output end of the first motor rotates. With the cooperation of the first gear, the second gear and the threaded rod and other parts, the support block can be made to vibrate continuously, which can prevent solid waste from squeezing each other and getting stuck at the filter port, thus affecting the normal screening of the equipment.

[0031] 2. In this invention, when in use, the second motor is started, causing the second rotating shaft set at the output end of the second motor to rotate. With the cooperation of the third gear, the fourth gear and other parts, the screening screen can be unfolded to facilitate the screening of solid waste entering the screening box. At the same time, after screening is completed, the screening screen can be retracted to facilitate the larger particles of solid waste screened by the screening screen to fall down for collection.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0042] Example 1

[0043] like Figure 1-7 As shown, a recycling device for screening and utilizing mining solid waste includes a screening box 1. The screening box 1 is equipped with a vibration mechanism. The vibration mechanism includes a first rotating shaft 4 installed inside the screening box 1. A first connecting block 6 is fixedly connected to the outside of the first rotating shaft 4. A second connecting block 7 is fixedly connected to the outside of the first connecting block 6. A third connecting block 8 is rotatably connected to the outside of the second connecting block 7. A support block 2 is fixedly connected to the side of the third connecting block 8 away from the second connecting block 7.

[0044] The support block 2 is provided with a retractable mechanism. The retractable mechanism includes a fourth connecting block 17 disposed outside the support block 2. A third rotating shaft 31 is rotatably connected to the outside of the fourth connecting block 17. A rotating block 19 is fixedly connected to the outside of the third rotating shaft 31. A first connecting rod 18 is fixedly connected to the outside of the rotating block 19. A second rotating shaft 28 is rotatably connected to the outside of the fourth connecting block 17. The second rotating shaft 28 and the rotating block 19 are fixedly connected.

[0045] The working principle of the recycling device and method for screening and utilizing mining solid waste proposed in this invention is as follows: When the device screens mining solid waste such as coal gangue and slag, the first rotating shaft 4 rotates, which in turn drives the externally fixed first connecting block 6 to rotate. The second connecting block 7 is fixedly connected to the edge of the first connecting block 6. Therefore, when the first connecting block 6 rotates, it causes the second connecting block 7 to move up and down. This up and down movement of the second connecting block 7 causes the externally rotating third connecting block 8 to move up and down. The third connecting block 8 then causes the externally fixed support block 2 to vibrate continuously, thus preventing... To prevent solid waste from squeezing and getting stuck at the filter opening, which would affect the normal screening of the equipment, after screening, the third rotating shaft 31 and the second rotating shaft 28 of the receiving and discharging mechanism are rotated. When the third rotating shaft 31 and the second rotating shaft 28 rotate, they will drive the externally fixed rotating block 19 to rotate. The rotating block 19 will cause the externally fixed first connecting rod 18 to tilt at an angle, so that the screening screen 10 set outside the fourth connecting block 17 can be stored in the upper part of the fourth connecting block 17 fixedly connected to the support block 2. The larger solid waste particles screened by the screening screen 10 can fall into the bottom of the screening box 1 for easy collection.

[0046] Example 2

[0047] like Figure 1-7 As shown, based on Embodiment 1, a second motor 9 is fixedly installed on the outside of the fourth connecting block 17. The output end of the second motor 9 is fixedly connected to the second rotating shaft 28. A third gear 29 is fixedly connected to the outside of the second rotating shaft 28. A fourth gear 30 is meshed with the outside of the third gear 29. The fourth gear 30 is fixedly connected to the third rotating shaft 31. A telescopic rod 21 is slidably connected to the outside of the support block 2. The side of the telescopic rod 21 away from the support block 2 is fixedly connected to the fourth connecting block 17. A sliding groove 20 is opened inside the screening box 1. A first connecting plate 11 is slidably connected to the outside of the sliding groove 20. The first connecting plate 11 is fixedly connected to the support block 2. A first motor 3 is fixedly installed on the outside of the screening box 1. The output end of the first motor 3 is fixedly connected to the first rotating shaft 4.

[0048] A first gear 12 is fixedly connected to the outside of the first rotating shaft 4. A second gear 13 is meshed with the outside of the first gear 12. A threaded rod 22 is fixedly connected to the outside of the second gear 13. A first slider 23 is threadedly connected to the outside of the threaded rod 22. A third connecting rod 27 is fixedly connected to the outside of the first slider 23. A second connecting plate 14 is fixedly connected to the side of the third connecting rod 27 away from the first slider 23. A cleaning column 15 is fixedly connected to the outside of the second connecting plate 14. A second connecting rod 24 is fixedly connected to the outside of the first slider 23. A second slider 25 is fixedly connected to the outside of the second connecting rod 24. A fixed rod 26 is slidably connected to the outside of the second slider 25. The fixed rod 26 is fixedly connected to the screening box 1. A screening screen 10 is provided on the outside of the fourth connecting block 17. A collection box 5 is provided inside the screening box 1. An inlet 16 is fixedly connected to the outside of the screening box 1.

[0049] The working principle of the recycling device and method for screening and utilizing mining solid waste proposed in this invention is as follows: Based on Embodiment 1, the second motor 9 is started, causing the second rotating shaft 28 set at the output end of the second motor 9 to rotate. The rotation of the second rotating shaft 28 causes the externally fixedly connected third gear 29 to rotate, and the third gear 29 causes the meshing fourth gear 30 to rotate, which in turn drives the third rotating shaft 31 to rotate, facilitating retraction and extension. The telescopic rod 21 slidably connected to the outside of the support block 2 is fixedly connected to the fourth connecting block 17, which facilitates stability when the fourth connecting block 17 moves. The sliding groove 20 opened on the outside of the screening box 1 is symmetrically arranged, which facilitates stability when the support block 2 vibrates. The first motor 3 can easily drive the first rotating shaft 4 set at the output end to rotate, and the first rotating shaft 4 causes the fixedly connected first gear 12 to rotate.

[0050] The first gear 12 causes the externally meshing second gear 13 to rotate, which in turn drives the externally fixed threaded rod 22 to rotate. The first slider 23 is externally threadedly connected to the first motor 3, which is fixedly connected to the second slider 25 via the second connecting rod 24, allowing the first motor 3 to slide only on the threaded rod 22. When the first motor 3 slides, it facilitates the sliding of the externally fixed third connecting rod 27. The second connecting plate 14 and the cleaning column 15 externally fixed to the third connecting rod 27 facilitate the pushing of smaller coal gangue, slag, and other mining solid wastes that fall during screening into the collection box 5 for collection and utilization. The fixing rod 26 facilitates the sliding of the second slider 25, thus restricting the first slider 23. After the smaller solid wastes are collected, the collection box 5 is replaced, causing the collection and dispensing mechanism to retract. At this time, the vibration mechanism is activated, allowing the larger solid wastes collected outside the screening screen 10 to fall to the bottom of the screening box 1. Similarly, the larger solid wastes can be collected inside the replaced collection box 5 for utilization.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
