[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a device suitable for continuous treatment of coal slime in coal mines, including a support platform 1 and a frame 5 fixedly connected to its top. Multiple first springs 4 are fixedly connected to the top of the frame 5. A processing box 3 is fixedly connected to the top of the first springs 4. A second screen 31 is fixedly connected to the inner side of the processing box 3. A collection trough 32 is provided at the bottom of the second screen 31. A sewage outlet 33 is fixedly connected to the bottom of the processing box 3. The sewage outlet 33 communicates with the collection trough 32. A guide port 34 is fixedly connected to the center of one side of the processing box 3. A processing mechanism 2 is installed on one side of the support platform 1.

[0025] The processing mechanism 2 includes a mounting platform 21 and a screening box 24. A push rod 261 is fixedly connected to one side of the screening box 24, and a reciprocating frame 26 is fixedly connected to one end of the push rod 261. A crank 27 is rotatably connected to one side of the mounting platform 21, and a drive rod 271 is fixedly connected to one end of the crank 27. The drive rod 271 is slidably connected to the reciprocating frame 26.

[0026] The specific setup and function of this embodiment will be described in detail below. In the coal slurry processing, the coal slurry is first poured into the inner side of the processing box 3. Under the action of gravity, the coal slurry slides down along the second screen 31, and during this process, sewage and fine sludge fall smoothly into the inner side of the collection trough 32. Subsequently, this sewage and sludge are discharged through the drain 33, achieving preliminary separation.

[0027] After the preliminary screening of sewage and sludge, the coal slime will be transported to the inside of the screening box 24 through the guide port 34. In this process, the rotation of the crank 27 will drive the driving rod 271 to exert force on the reciprocating frame 26. Due to the circular motion of the crank 27, the reciprocating frame 26 will move with the push rod 261, and the movement of the push rod 261 is limited by the side wall of the mounting table 21, so it can only make linear reciprocating motion. This design ensures the stability of the reciprocating frame 26, while improving the efficiency of screening.

[0028] With the movement of the reciprocating frame 26, the screening box 24 also reciprocates. Through this mechanical movement, the screening efficiency and effect of the first screen 241 are significantly improved, which can effectively screen out larger stones and impurities. The processed coal mine materials will settle at the bottom end of the screening box 24 and be smoothly discharged through the discharge port 23.

[0029] After continuous processing, the impurities in the coal slime can be quickly screened out, thereby improving the recovery efficiency of the coal mine. This process not only improves the processing speed of the coal slime, but also ensures the purity of the recovered coal mine, laying a foundation for the subsequent use of the coal mine.

[0030] Embodiment two: as shown in Figure 2 Figure 4 The mounting table 21 has a discharge port 23 in the middle, and the screening box 24 passes through the discharge port 23. The top of the mounting table 21 is symmetrically provided with two guide grooves 22, and the inner side of the guide groove 22 is slidably connected with a guide block 242. The top of the guide block 242 is fixedly connected with the screening box 24, and the inner side of the screening box 24 is fixedly connected with a first screen 241. The screening box 24 is symmetrically fixedly connected with two movable rods 29 on one side, and the movable rod 29 penetrates through the mounting table 21 on one end, and the movable rod 29 is slidably connected with the mounting table 21. The screening box 24 is provided with a second spring 28 on one side, and the second spring 28 is sleeved on the outer surface of the movable rod 29. The mounting table 21 is provided with a driving motor 25 on the side wall, and the output end of the driving motor 25 is fixedly connected with a crank 27. The inner side of the frame 5 is provided with a driving device 7, and the driving device 7 is fixedly connected with an eccentric rod 6. The outer surface of the eccentric rod 6 is rotatably connected with a support frame 8, and the support frame 8 is fixedly connected with the frame 5.

[0031] The effect of the whole embodiment is that during the operation of the driving device 7, the operation of the driving motor 25 can effectively drive the eccentric rod 6 to continuously rotate. When the eccentric rod 6 rotates, it will exert a reciprocating force on the processing box 3, and this repeated motion will cause the processing box 3 to shake strongly. With the assistance of the first spring 4, this shaking can significantly improve the screening effect, thereby improving the screening efficiency of the sludge.

[0032] ​With the continuous operation of the driving motor 25, the rotation of the crank 27 will push the reciprocating frame 26 to jointly act on the screening box 24, so that the screening box 24 reciprocates. In this process, the guide block 242 slides in the guide groove 22, ensuring the stability of the screening box 24 during reciprocating movement. In addition, the limiting function of the movable rod 29 will make the screening box 24 extrude the second spring 28 during movement, thereby compressing the spring.

[0033] The elasticity of the second spring 28 plays an important role in resetting after the screening box 24 completes the screening work. When the screening box 24 returns to the initial position, the second spring 28 will quickly recover to the original shape, helping the screening box 24 to prepare for the next cycle. This design not only improves the operation efficiency of the equipment, but also ensures the stability and continuity of the screening process, which helps to improve the working efficiency of the whole sludge treatment system. Through the above mechanism, the screening efficiency of sludge is greatly improved, further optimizing the coal mine treatment process.

[0034] The use method and working principle of the device: when the coal mine slurry is treated, it is first poured into the inside of the treatment box 3, and when the coal slurry slides down along the second screen 31, sewage and sludge will fall into the material collecting groove 32 and be discharged through the sewage outlet 33. After the preliminary screening of sewage and sludge, the coal slurry is conveyed into the screening box 24 through the material guide port 34. At this time, the rotation of the crank 27 will use the driving rod 271 to exert force on the reciprocating frame 26, and due to the circular motion of the crank 27, the reciprocating frame 26 will drive the push rod 261 to move together, which is limited by the side wall of the mounting table 21, so that it can only move linearly, thereby pushing the screening box 24 to move together. After the reciprocating movement of the screening box 24, the screening efficiency and effect of the first screen 241 are improved, and stone blocks and large impurities can be effectively screened out, while the required coal mine falls into the bottom end of the screening box 24 and is discharged. Through continuous treatment, the coal slurry can quickly screen a large amount of impurities for recycling of coal mine.

[0035] In addition, by using the operation of the driving device 7, the eccentric rod 6 will continuously rotate, and in this process, the reciprocating force is exerted on the treatment box 3, and under the assistance of the first spring 4, the treatment box 3 will shake strongly, thereby improving the screening effect and sludge screening efficiency. Under the action of the driving motor 25, the rotation of the crank 27 drives the reciprocating frame 26 to push the screening box 24 to reciprocate. At this time, the guide block 242 slides in the guide groove 22, ensuring the stability of the screening box 24, and through the limiting action of the movable rod 29, the screening box 24 extrudes the second spring 28, compresses the second spring 28, and at the same time, uses the elasticity of the second spring 28 to facilitate the resetting of the screening box 24, thereby further improving the screening efficiency.

[0036] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
