Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, specifically to a coal gangue solid waste treatment device. Background Technology

[0002] In the coal mining and processing industry, coal gangue is an unavoidable byproduct of coal mining and washing. The treatment of coal gangue is not only related to the protection of the ecological environment, but also directly affects the economic benefits and sustainable development of coal enterprises.

[0003] In related technologies, the treatment of coal gangue mostly involves directly immersing it in a washing tank containing a cleaning solution. Prolonged soaking softens or dissolves impurities and deposits on the surface of the gangue, enabling effective separation of the gangue from valuable minerals during subsequent screening. However, while this method can improve separation efficiency to some extent, its significant drawback lies in the excessively long soaking time of the gangue in the cleaning solution, leading to low efficiency and increased processing costs. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art. To this end, an embodiment of the present invention proposes a coal gangue solid waste treatment device, which can improve the washing efficiency of coal gangue and also improve the cleanliness of coal gangue.

[0005] The coal gangue solid waste treatment device provided by the present invention includes a cavity and a conveying assembly. The cavity is provided with a washing chamber. The conveying assembly includes a conveying pipe and a first spiral blade. The conveying pipe is connected to the washing chamber. The conveying pipe is provided with a feed inlet and a liquid inlet. The feed inlet is used to dispense coal gangue, and the liquid inlet is used to dispense washing liquid. The first spiral blade is rotatably disposed in the conveying pipe. The first spiral blade is used to mix the coal gangue and the washing liquid in the conveying pipe and convey them to the washing chamber.

[0006] Therefore, the coal gangue solid waste treatment device provided by the present invention, through the rotation of the first spiral blade in the conveying pipe, not only enables the coal gangue to be fully mixed and preliminarily soaked with the cleaning liquid, thereby improving the cleaning efficiency, but also the first spiral blade has a pressurizing effect on the cleaning liquid, further enhancing the penetration ability of the cleaning liquid, thereby improving the soaking treatment efficiency of coal gangue and helping to improve the cleanliness of coal gangue.

[0007] In some embodiments, the feeding assembly further includes a soft pad disposed on the inner wall of the feeding pipe, and the edge of the first helical blade is disposed in contact with the soft pad.

The partition is disposed between the collection chamber and the immersion chamber to separate the collection chamber and the immersion chamber. The adjusting plate is connected to the partition and is movable relative to the partition in the depth direction of the immersion chamber.

[0014] In some embodiments, the adjustment plate has a third plate and a fourth plate connected to each other, the third plate being connected to the partition, the fourth plate extending from the third plate toward the immersion chamber, and the fourth plate having an inclined surface.

[0016] And / or, in the depth direction of the immersion chamber, the top surface of the movable plate is higher than the top surface of the adjusting plate.

[0017] In some embodiments, the system further includes an open trough, a second spiral blade, and a discharge pipe.

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1 to 5 As shown, this embodiment of the invention provides a coal gangue solid waste treatment device 100, which includes a cavity 10 and a conveying assembly 20. The cavity 10 is provided with a washing chamber 11. The conveying assembly 20 includes a conveying pipe 21 and a first spiral blade 22. The conveying pipe 21 is connected to the washing chamber 11. The conveying pipe 21 is provided with a feed inlet 211 and a liquid inlet 212. The feed inlet 211 is used to dispense coal gangue, and the liquid inlet 212 is used to dispense washing liquid. The first spiral blade 22 is rotatably disposed within the conveying pipe 21, and the first spiral blade 22 is used to mix the coal gangue and washing liquid within the conveying pipe 21 and convey them to the washing chamber 11.

[0035] Specifically, the conveying pipe 21 is equipped with a feed inlet 211 and a liquid inlet 212, which allow for the separate addition of coal gangue and cleaning fluid. That is, the feed inlet 211 is responsible for continuously and stably conveying the coal gangue to be processed into the conveying pipe 21; the liquid inlet 212 is responsible for introducing the cleaning fluid into the conveying pipe 21 at a certain flow rate and pressure, ensuring that the cleaning fluid can mix with the coal gangue in the conveying pipe 21.

[0036] Furthermore, the first helical blade 22, rotatably positioned within the conveying pipe 21, not only propels the coal gangue and cleaning fluid forward within the pipe 21, but also promotes thorough mixing of the coal gangue and cleaning fluid through the shearing and compressive forces generated by its rotation. In addition, the rotation of the first helical blade 22 also pressurizes the mixture formed by the cleaning fluid and coal gangue, resulting in a more thorough cleaning of the coal gangue by the cleaning fluid and improving the washing effect.

[0037] In the use of the coal gangue solid waste treatment device 100 provided by the present invention, coal gangue is continuously added to the conveying pipe 21 through the feed inlet 211, while the cleaning liquid is injected into the conveying pipe 21 through the liquid inlet 212 at a certain flow rate and pressure. As the first spiral blade 22 rotates, the coal gangue can be continuously turned over under the action of the spiral and fully mixed with the cleaning liquid to form a mixture. The mixture will gradually reach a uniform state during the conveying process and is finally conveyed to the immersion chamber 11 for preliminary immersion treatment.

[0038] In summary, the coal gangue solid waste treatment device 100 provided by the present invention, through the rotation of the first spiral blade 22 in the conveying pipe, not only enables the coal gangue to be fully mixed and preliminarily soaked with the cleaning liquid, thereby improving the cleaning efficiency, but also the first spiral blade 22 has a pressurizing effect on the cleaning liquid, further enhancing the penetration ability of the cleaning liquid, thereby improving the soaking treatment efficiency of coal gangue and helping to improve the cleanliness of coal gangue.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, a feed hopper 213 is provided at the feed inlet 211, which not only reduces the splashing and scattering of coal gangue during the feeding process, but also guides the flow of coal gangue, allowing it to enter the washing chamber 11 more smoothly. Furthermore, the cleaning fluid provided in this embodiment can be hydrochloric acid, with a concentration of 20%. Of course, in some embodiments, the cleaning fluid can also be hydrofluoric acid, etc.

[0040] Furthermore, a mounting bracket 30 can be provided at the bottom of the cavity 10, which not only provides a solid support platform for the cavity 10, but also gives the cavity 10 a certain degree of free-floating capability. This free-floating design means that the cavity 10 can be adjusted in height according to actual processing needs, or can be easily disassembled, moved and reinstalled, thereby greatly improving the flexibility and operability of the equipment.

[0041] like Figure 2 As shown, in some embodiments, the feeding assembly 20 further includes a soft pad 214, which is disposed on the inner wall of the feeding pipe 21, with the edge of the first helical blade 22 adhering to the soft pad 214. Since the soft pad 214 adheres to the inner wall of the feeding pipe 21, when the first helical blade 22 rotates, its edge contacts the soft pad 214 instead of directly rubbing against the inner wall of the feeding pipe 21, thereby slowing down the wear rate of the helical blade and the feeding pipe 21 and helping to extend its service life.

[0042] Furthermore, the soft pad 214 can also form a relatively sealed channel between the conveying pipe 21 and the first spiral blade 22, which can reduce the leakage of the cleaning fluid during the conveying process and ensure that the cleaning fluid can be effectively pushed and pressurized by the first spiral blade 22, thereby helping to improve the mixing effect and washing efficiency of coal gangue and cleaning fluid.

[0043] Optionally, the soft pad 214 may be made of a wear-resistant, corrosion-resistant and elastic material, such as a polymer or rubber.

[0044] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the cavity 10 is provided with a material inlet 111, which is connected to the conveying pipe 21. The material inlet 111 is located at the bottom or lower middle part of the immersion cavity 11, which can make the flow path of coal gangue in the immersion cavity 11 longer, so as to obtain a longer soaking time and thus improve the immersion effect of coal gangue.

[0045] When the mixture of coal gangue and cleaning fluid is introduced into the bottom or lower-middle part of the immersion chamber 11 through the conveying pipe 21, the coal gangue first sinks into the depth of the cleaning fluid, rather than being placed directly on the surface or in the middle of the cleaning fluid. This allows the coal gangue to have a more sufficient contact area and time with the cleaning fluid. Subsequently, under the buoyancy of the cleaning fluid, the coal gangue gradually floats to the surface, ensuring that every surface of the coal gangue is exposed to the cleaning fluid and receives a complete cleaning treatment.

[0046] In contrast, if the feed inlet 111 is located in the upper middle or top of the washing chamber 11, the sinking process of the coal gangue after entering the washing chamber 11 will be relatively short, and it may even remain near the liquid surface, resulting in some surfaces of the coal gangue not being fully soaked. However, by placing the feed inlet 111 at the bottom or lower middle of the washing chamber 11, the floating process of the coal gangue becomes a naturally prolonged soaking process. This not only increases the contact area between the coal gangue and the cleaning liquid, but also significantly extends the overall soaking time, thereby achieving a deeper cleaning effect.

[0047] Furthermore, since the coal gangue floats upwards from the bottom or lower middle part of the washing chamber 11, its distribution within the washing chamber 11 is more uniform, avoiding blind spots in the cleaning caused by the pushing of coal gangue. This not only improves the cleaning efficiency but also ensures that each piece of coal gangue receives the same treatment, further enhancing the stability and reliability of the washing effect.

[0048] In this embodiment, the feed inlet 111 is located in the lower middle part of the immersion chamber 11, which can prevent coal gangue from depositing and clogging the feed inlet 111, thus affecting the entry of the mixture of coal gangue and cleaning fluid into the immersion chamber 11.

[0049] like Figure 4 and Figure 5 As shown, in some embodiments, the coal gangue solid waste treatment device 100 further includes a movable plate 40, which is movably disposed in the washing chamber 11. The chamber 10 is also provided with a collection chamber 12 adjacent to the washing chamber 11. The movable plate 40 is used to push the coal gangue in the washing chamber 11 into the collection chamber 12.

[0050] After the coal gangue is soaked, it floats on the surface of the washing liquid. When the movable plate 40 moves within the soaking chamber 11, it can push the coal gangue floating on the surface of the washing liquid from one end of the chamber 11 to the other end until it is smoothly guided into the adjacent collection chamber 12. At the same time, the movable plate 40 can also agitate the washing liquid during its movement, promoting full contact between the coal gangue and the washing liquid and improving the washing effect.

[0051] Furthermore, the movable plate 40 has a first plate body 41 and a second plate body 42 connected to each other. The first plate body 41 extends along the depth direction of the immersion chamber 11, and the second plate body 42 extends from the first plate body 41 toward the collection chamber 12. That is, at least a portion of the first plate body 41 can penetrate deep into the interior of the immersion chamber 11, thereby contacting and agitating coal gangue at different depths, especially the heavier coal gangue particles deposited at the bottom of the cleaning fluid, thus improving the cleaning effect.

[0052] The second plate 42 extends from one end of the first plate 41 and is typically located on the side of the first plate 41 facing the collection chamber 12. During the movement of the movable plate 40, the second plate 42 can be positioned above a portion of the coal gangue, thereby easily pushing the coal gangue floating on the surface of the cleaning fluid into the collection chamber 12, achieving rapid and efficient collection of the coal gangue. In this embodiment, the movable plate 40 is L-shaped, meaning the first plate 41 and the second plate 42 are perpendicular to each other.

[0053] Furthermore, the movable plate 40 is provided with multiple through holes 411 to ensure that the cleaning fluid can flow freely within the immersion chamber 11 without being obstructed by the movement of the movable plate 40. In this way, even when the movable plate 40 is pushing the coal gangue, the cleaning fluid can continuously contact the surface of the coal gangue, thereby maintaining a highly efficient cleaning effect. In this embodiment, the through holes 411 can be provided on the first plate 41.

[0054] Secondly, the through-hole 411 also helps to reduce the weight of the movable plate 40 and improve its mobility. In the coal gangue solid waste treatment device 100, the movable plate 40 needs to move frequently to push the coal gangue. If the movable plate 40 is too heavy, it will not only increase the burden on the drive device, but may also affect the pushing speed and stability. The design of the through-hole 411 can effectively reduce the weight of the movable plate 40 while ensuring its structural strength, making the movement of the movable plate 40 easier and more free.

[0055] Furthermore, as the movable plate 40 moves forward, the through hole 411 allows some cleaning fluid and smaller coal gangue particles to pass through, thereby forming a thin lubricating layer between the movable plate 40 and the coal gangue. This lubricating layer reduces the frictional resistance between the movable plate 40 and the coal gangue, making the pushing process smoother, and also reducing the possibility of breakage or wear of the coal gangue during the pushing process.

[0056] In this embodiment, two collection chambers 12 are provided, which are located opposite each other on both sides of the washing chamber 11, which can greatly improve the collection effect and efficiency of coal gangue. First, the setting of two collection chambers 12 means that during the coal gangue processing, there are two independent collection spaces to receive the pushed-out coal gangue, which can significantly increase the collection capacity and reduce the downtime for cleaning caused by overflow of the collection chambers 12, thereby improving the continuous operation capability of the equipment.

[0057] Secondly, the two collection chambers 12 are positioned opposite each other on both sides of the washing chamber 11, so that the movable plate 40 can effectively push the coal gangue floating above the washing liquid into the nearest collection chamber 12 during the reciprocating motion, regardless of its direction of motion. This avoids the retention and accumulation of coal gangue in the washing chamber 11, ensuring that the coal gangue can be collected and processed in a timely and efficient manner.

[0058] Furthermore, the symmetrical arrangement of the two collection chambers 12 helps to balance the forces acting on the equipment during operation, reducing vibration and wear caused by excessive forces on one side, thus extending the service life of the device and improving operational stability and reliability. Figure 1 and Figure 3 In the coal gangue solid waste treatment device 100 shown, one of the two collection chambers 12 is located on the left side of the cavity 10, the immersion chamber 11 is located in the middle of the cavity 10, and the other of the two collection chambers 12 is located on the right side of the cavity 10.

[0059] In addition, the edge of the movable plate 40 is set to fit against the inner wall of the immersion chamber 11, so that when the coal gangue is pushed, the edge of the movable plate 40 will rub against the inner wall of the immersion chamber 11, which can effectively remove impurities or residues attached to the inner wall of the immersion chamber 11, thereby improving the cleaning requirements of the movable plate 40 itself.

[0060] Optionally, a flexible pad may be provided at the edge of the movable plate 40 to reduce wear on the movable plate 40 and the inner wall of the immersion chamber 11.

[0061] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, two second plates 42 are provided, and the two second plates 42 are disposed opposite each other on both sides of the first plate 41. Of course, in some embodiments, two movable plates 40 may be provided, and the two movable plates 40 are disposed back-to-back.

[0062] Furthermore, the coal gangue solid waste treatment device 100 also includes a first pushing assembly 43, which includes a first pushing rod 431 and a fixing frame 432. The fixing frame 432 is disposed on the side wall of the cavity 10. The first pushing rod 431 has a fixed end 4311 and a pushing end 4312. The first pushing rod 431 is installed on the fixing frame 432 through the fixed end 4311. The pushing end 4312 of the first pushing rod 431 is connected to the movable plate 40 to push the movable plate 40 to reciprocate within the immersion chamber 11.

[0063] Furthermore, the first pushing component 43 is configured as two sets, with the two sets of first pushing components 43 respectively located on opposite sides of the movable plate 40. That is, during the movement of the movable plate 40, one of the two sets of first pushing components 43 applies a pushing force to the movable plate 40, and the other of the two sets of first pushing components 43 applies a pulling force to the movable plate 40, thereby improving the movement efficiency of the movable plate 40.

[0064] like Figure 5 As shown, in some embodiments, the coal gangue solid waste treatment device 100 further includes a partition 51 and an adjusting plate 52. The partition 51 is disposed between the collection chamber 12 and the immersion chamber 11 to separate the collection chamber 12 and the immersion chamber 11. The adjusting plate 52 is connected to the partition 51 and is movable relative to the partition 51 in the depth direction of the immersion chamber 11, thereby adapting to the differences in particle size of different batches of coal gangue and improving the flexibility and practicality of the device.

[0065] Specifically, the partition 51 can serve as a physical barrier between the collection chamber 12 and the washing chamber 11, clearly separating the two functional areas. This ensures that the circulation of the cleaning fluid in the washing chamber 11 and the washing process of the coal gangue are not affected by the collection operation, while also effectively preventing the collected coal gangue from being mixed back into the washing chamber 11.

[0066] Furthermore, the adjusting plate 52 moves relative to the partition plate 51 in the depth direction of the immersion chamber 11, so that its height can be adjusted according to the actual size of the coal gangue particles, so that the upper end of the adjusting plate 52 is located at the lower half of the coal gangue particles, ensuring that the coal gangue particles can smoothly pass over the adjusting plate 52 and enter the collection chamber 12.

[0067] Furthermore, the adjusting plate 52 has a third plate body 521 and a fourth plate body 522 connected to each other. The third plate body 521 is connected to the partition plate 51, and the fourth plate body 522 extends from the third plate body 521 toward the washing chamber 11. The fourth plate body 522 is provided with an inclined surface, which facilitates the coal gangue to pass over the top of the adjusting plate 52 and enter the collection chamber 12, thereby achieving effective collection of coal gangue. In this embodiment, the third plate body 521 can be perpendicular to the fourth plate body 522, that is, the adjusting plate 52 is L-shaped.

[0068] Furthermore, the fourth plate 522 is provided with multiple through holes 5221, allowing the cleaning fluid adhering to the surface of the coal gangue to drip back into the immersion chamber 11 through the through holes 5221 during the coal gangue's residence and movement. In this way, before the coal gangue crosses the fourth plate 522 and enters the collection chamber 12, most of the carrying cleaning fluid has been removed, which not only reduces the weight of the coal gangue but also improves the dryness and collection efficiency of the collection chamber 12.

[0069] It should be noted that, in the depth direction of the washing chamber 11, the top surface of the movable plate 40 is higher than the top surface of the adjusting plate 52. This ensures that the coal gangue can be smoothly pushed over the adjusting plate 52 and enter the collection chamber 12. If the top surface of the movable plate 40 is lower than the top surface of the adjusting plate 52, the coal gangue may be obstructed by the adjusting plate 52 when being pushed, preventing it from smoothly passing over and entering the collection chamber 12. Figure 4 As shown, the fourth plate 522 of the movable plate 40 is always higher than the second plate 42 of the adjustment plate 52.

[0070] In this embodiment, the coal gangue solid waste treatment device 100 further includes a second pushing component 53, which includes a second pushing rod 531 and a limiting plate 532. The second pushing rod 531 can be installed on the partition 51, and the pushing end 5311 of the second pushing rod 531 can be connected to the third plate 521. The limiting plate 532 is arranged parallel to the partition 51, and the third plate 521 is sandwiched between the limiting plate 532 and the partition 51, thereby limiting the moving direction of the third plate 521, ensuring the moving accuracy of the adjusting plate 52, and preventing the adjusting plate 52 from deviating.

[0071] like Figure 5 As shown, in some embodiments, the coal gangue solid waste treatment device 100 further includes a baffle 54, and a discharge port 511 is provided on the partition 51. The baffle 54 is movably disposed at the discharge port 511 to open or block the discharge port 511. That is, the discharge port 511 can be used to connect the collection chamber 12 and the washing chamber 11. When the baffle 54 moves at the discharge port 511 to open the discharge port 511, the coal gangue and washing liquid in the washing chamber 11 can enter the collection chamber 12 through the discharge port 511.

[0072] Furthermore, the coal gangue solid waste treatment device 100 also includes a third pushing component 55, which further includes a third pushing rod 551. The third pushing rod 551 can be fixed to the side wall of the cavity 10, and the movable end 552 of the third pushing rod 551 can be connected to the baffle 54. The third pushing rod 551 can drive the baffle 54 to move back and forth at the discharge port 511 through the movable end 552.

[0073] like Figure 5As shown, in some embodiments, the coal gangue solid waste treatment device 100 further includes an open trough 56, a second spiral blade 57, and a discharge pipe 58. The open trough 56 is located at the bottom of the collection chamber 12 and is connected to the discharge pipe 58. The second spiral blade 57 is rotatably disposed in the open trough 56 and is used to transport the coal gangue in the open trough 56 to the discharge pipe 58, thereby transporting the coal gangue in the collection chamber 12 to the next station.

[0074] Specifically, the discharge pipe 58 can be installed in the cavity 10 to transport the coal gangue in the collection cavity 12 to the next working position. The upper part of the open trough 56 is open, and the open trough 56 is located at the bottom of the collection cavity 12. The coal gangue in the washing cavity 11 can enter the collection cavity 12 after passing over the adjusting plate 52, and then be deposited in the open trough 56. Under the rotation of the second spiral blade 57, the coal gangue in the open trough 56 can be transported to the next working position through the discharge pipe 58. Furthermore, for the residual coal gangue in the washing cavity 11, the movable plate 40 can also push the coal gangue in the washing cavity 11 to the open trough 56 during the movement of the washing cavity 11, thereby realizing the collection of coal gangue.

[0075] In this embodiment, the open trough 56 can be configured as an arc to accommodate the rotating edge of the second spiral blade 57, ensuring that the coal gangue in the collection chamber 12 can be completely transported to the discharge pipe 58.

[0076] It should be noted that the coal gangue solid waste treatment device 100 also includes a drive assembly, which drives the first helical blade 22 and the second helical blade 57 to rotate. In this embodiment, the drive assembly can be configured in two sets, such that the drive assembly corresponds one-to-one with the first helical blade 22 and the second helical blade 57. The two sets of drive assemblies can be divided into a first drive assembly 61 and a second drive assembly 62. The first drive assembly 61 can be connected to the first helical blade 22 to drive the first helical blade 22 to rotate. The second drive assembly 62 can be connected to the second helical blade 57 to drive the second helical blade 57 to rotate.

[0077] Furthermore, the drive component can be configured as a motor or pneumatic motor, etc., to adapt to the needs of different processing conditions.

[0078] In addition, the usage process of the coal gangue solid waste treatment device 100 provided in this embodiment of the invention is as follows: the first driving component 61 drives the first spiral blade 22 to rotate in the conveying pipe; the coal gangue is added to the conveying pipe 21 through the feed hopper 213 on the feed inlet 211, and the cleaning liquid is added to the conveying pipe through the liquid inlet 212. The first spiral blade 22 can drive the coal gangue and the cleaning liquid to mix in the conveying pipe 21 and be conveyed to the washing chamber 11. The coal gangue can gradually float above the liquid surface of the cleaning liquid in the washing chamber 11. Then the movable plate 40 can move back and forth in the washing chamber 11 to transfer the coal gangue in the washing chamber 11 and pass over the adjustment plate 52 into the collection chamber 12; the second driving component 62 can drive the second spiral blade 57 to rotate in the open trough 56, thereby conveying the coal gangue in the collection chamber 12 to the next station through the open trough 56 and the discharge pipe 58.

[0079] Furthermore, when the coal gangue solid waste treatment device 100 has been running for a period of time or when a large amount of coal gangue has been deposited in the washing chamber 11, the discharge port 511 can be opened by the baffle 54, and the movable plate 40 can be driven to move in the washing chamber 11 to push the coal gangue deposited in the washing chamber 11 into the open trough 56, and then transported to the next station through the discharge pipe 58.
