Description

Technical Field

[0001] This invention relates to the field of coal-based solid waste paste preparation technology, specifically to a preparation device for coal-based solid waste filling paste and its usage method. Background Technology

[0002] Paste backfilling mining technology can not only effectively release coal under pressure from the "three underground" and improve the coal resource recovery rate, but the backfilling material is the core of the entire backfilling system. At present, the main backfilling material is coal gangue. In the preparation process, the screened fly ash, gasification slag, bottom ash and desulfurized gypsum fine particles are usually mixed with flocculants to form a high-concentration slurry paste to achieve the preparation of paste.

[0003] However, in traditional technology, the relative positions of the cylinder cover and the agitator mean that the agitator must be completely removed during the repeated loading and unloading of the cylinder. Since the agitator usually goes deeper, it needs to be moved a greater distance during removal to allow for subsequent loading and unloading processes. This results in low loading and unloading efficiency during cylinder replacement, affecting the overall processing efficiency.

[0004] Furthermore, in traditional technology, the positions of the lid and the agitator are usually far apart. That is, the lid needs to be fastened to the upper edge of the cylinder, while the agitator needs to be inserted into the cylinder. This results in the lower part of the lid being too long after the agitator is removed, which can easily cause the agitator to be accidentally bumped and damaged.

[0005] Meanwhile, in traditional technology, after batches of barrels have completed preparation, users usually need to manually remove the barrels once to replace them and clamp and position them. This results in the inability to automatically replace barrels in batches during use, causing excessively long intervals between mixing and preparation of multiple groups, which affects the preparation efficiency. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the background, such as the need to move a greater distance during the removal of the agitator before the subsequent loading and unloading process, which leads to low loading and unloading efficiency during the replacement of the material cylinder, affecting the overall processing efficiency; the excessive length of the agitator exposed under the cylinder cover, which makes the agitator prone to accidental damage; and the inability to automatically replace the material cylinder in batches, resulting in excessively long intervals between multiple sets of mixing and preparation, affecting the preparation efficiency. Therefore, this invention proposes a preparation device for coal-based solid waste filling paste.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A device for preparing coal-based solid waste filling paste is designed, comprising a processing platform and a support frame. Multiple rollers are rotatably connected to the inner left side of the processing platform. A bottom support is provided inside the lower part of the support frame.

[0010] The material stop is located on the upper front right side of the processing platform. The lower end of the internal rotating shaft of the material stop is fixedly connected to the second small gear, and the outer wall of the internal rotating shaft of the material stop is rotatably connected to the processing platform through a bearing seat. The right side of the outer wall of the second small gear is meshed with the first large gear. The lower end of the internal rotating shaft of the first large gear is fixedly connected to the first small gear, and the outer wall of the internal rotating shaft of the first large gear is rotatably connected to the processing platform through a bearing seat. The rear side of the outer wall of the first small gear is meshed with the second large gear. The lower end of the internal rotating shaft of the second large gear is fixedly connected to a slotted plate, and the outer wall of the internal rotating shaft of the second large gear is rotatably connected to the processing platform through a bearing seat. The rear side of the outer wall of the slotted plate is in contact with a crank, and a round rod is fixedly connected above the rear end of the crank. The center of the upper end of the crank is fixedly connected to the end of the output shaft of the material stop motor.

[0011] Preferably, the processing platform is fixedly connected to the upper end of the support frame, and a material cylinder baffle is installed on the upper right side of the processing platform.

[0012] Preferably, the drive assembly includes a fixed pulley, a drive motor, a traction rope, a stirrer, a main shaft, side strips, a vertical cylinder, and a sliding platform;

[0013] The sliding platform is slidably connected to the upper right side of the outer wall of the side support via a slide rail. The center of the left end of the sliding platform is fixedly connected to one end of the traction rope, and the other end of the traction rope is fixedly connected to the winding roller at the end of the power source inside the side support. Fixed pulleys are wound and connected to both sides of the upper part of the outer wall of the traction rope. The fixed pulleys are rotatably connected to both sides of the upper inner wall of the side support. Multiple drive motors are fixedly fixed at equal intervals on the right side of the outer wall of the sliding platform. The output shaft of the drive motor is fixedly connected to a vertical cylinder. A main shaft is intermittently fitted inside the vertical cylinder. A side strip is fixedly connected to one side of the outer wall of the main shaft. The outer wall of the side strip is slidably connected to the notch in the inner wall of the vertical cylinder. The lower part of the outer wall of the vertical cylinder is rotatably connected to the cylinder cover via a bearing. An agitator is fixedly connected to the lower end of the main shaft.

[0014] Preferably, rack supports are distributed on both the front and rear sides of the left side of the outer wall of the material cylinder, and the lower ends of the rack supports are fixedly connected to the processing platform.

[0015] Preferably, the linkage assembly includes a spur gear, an internal rack, a gear bracket, a slide bar, a bottom beam, and an external rack;

[0016] Multiple spur gears are distributed on the front and rear sides of the upper end of the cylinder cover. Gear brackets are rotatably connected to both sides of the shaft of each spur gear. The lower end of each gear bracket is fixedly connected to the cylinder cover. An inner rack and an outer rack are meshed on the inner and outer sides of the outer wall of each spur gear. The outer walls of the outer racks are fixedly connected to rack brackets. The lower part of the outer wall of the inner rack is slidably connected to the cylinder cover. A bottom beam is fixedly connected to the lower end of the inner rack. The center of the inner wall of the bottom beam is rotatably connected to the main shaft through a bearing. Multiple sliding rods are fixedly connected to both sides of the upper end of the cylinder cover, and the outer walls of the sliding rods are slidably connected to the rack brackets.

[0017] Preferably, the method of using a coal-based solid waste filling paste preparation device involves the user first assembling the overall structure. After assembly, the roller section of the device is aligned with the external conveying structure. Then, the fly ash, gasification slag, bottom ash, desulfurization gypsum fine particles, and flocculant required for mixing and preparation are pre-placed inside the material cylinder. Subsequently, the material is piled up at the external conveying structure and transported to the mixing and preparation station of this invention. The specific mixing and preparation process is as follows:

[0018] S1: Loading process: When loading and unloading are required, the user can control the baffle motor, so that the output shaft of the baffle motor drives the slot plate to perform intermittent transmission through the crank and the round rod. The transmission ratio is 4:1. At the same time, the slot plate can rotate synchronously with the large gear 2. Then, the large gear 2 can drive the small gear 1 to rotate. At the same time, the large gear 1 can rotate synchronously with the small gear 1. Then, the large gear 1 can drive the baffle frame to rotate by driving the small gear 2. However, since the transmission ratio between the large gear and the small gear in this case is set at 1:2, when the slot plate rotates 90°, the small gear 1 rotates half a turn, and the small gear 2 rotates one turn. Then, the baffle frame can rotate one turn. With the help of the rotating roller, the material cylinder is conveyed forward. The baffle frame can pass through four material cylinders in one turn, thus realizing the loading and unloading process of four material cylinders as a group.

[0019] S2: Linkage Process: After the material cylinder replacement is completed, the user can control the winding roller at the end of the power source in the side support to rotate, so that it controls the sliding platform to move downward by releasing the traction rope. During this process, the sliding platform drives the drive motor, vertical cylinder and cylinder cover to move downward synchronously until the cylinder cover completely covers the corresponding material cylinder. During this period, the spur gear rotates due to the obstruction of the external rack as it moves downward with the cylinder cover. At the same time, the rotation meshes with and drives the internal rack to move downward, so that the internal rack can drive the bottom beam to move further downward. That is, the cylinder cover moves downward a certain distance, and the bottom beam moves downward a distance of multiple times. Thus, in the open state, the agitator is closer to the position of the cylinder cover, and in the closed state, the agitator goes deeper into the inside of the material cylinder to stir. This realizes the linkage process between the agitator and the cylinder cover during the closing and lowering process.

[0020] S3: Stirring process: After the capping operation is completed, the user can control the drive motor to drive the output shaft of the drive motor to rotate the vertical cylinder. At the same time, since the vertical cylinder and the main shaft are connected by the side strip, the main shaft can move up and down on the inner wall of the vertical cylinder as it moves up and down with the bottom beam. The rotation between the vertical cylinder and the main shaft can always be transmitted through the side strip. After the agitator penetrates into the inside of the cylinder, the output shaft of the drive motor can drive the agitator to rotate through the vertical cylinder and the main shaft to achieve stirring and mixing inside the cylinder. After the preparation is completed, the sliding platform is controlled to move upward, so that the cylinder cap and the agitator move upward and move away from the lateral range of the cylinder. Repeating the above process can complete the preparation of continuous coal-based solid waste filling paste.

[0021] The present invention provides a device for preparing coal-based solid waste backfill paste, which has the following advantages:

[0022] Through the coordination between the sliding platform, drive motor, cylinder cover, vertical cylinder, agitator, external rack, internal rack, and bottom beam, the sliding platform drives the drive motor, vertical cylinder, and cylinder cover to move downwards synchronously until the cylinder cover completely covers the corresponding material cylinder. During this process, the spur gear rotates due to the obstruction of the external rack as it moves downwards with the cylinder cover. This rotation meshes with and drives the internal rack to move downwards, which in turn drives the bottom beam to move further downwards. That is, when the cylinder cover moves downwards a certain distance, the bottom beam moves downwards by a distance equal to that distance. This allows the agitator to be closer to the cylinder cover when the cover is open, and to penetrate deeper into the material cylinder when the cover is closed. When the agitator is removed, it can be removed by moving the sliding platform halfway, effectively avoiding the need to move a greater distance during the agitator removal process to proceed with subsequent loading and unloading. This avoids the problem of low loading and unloading efficiency during cylinder replacement, which affects the overall processing efficiency.

[0023] This design allows the agitator to be closer to the cylinder cover when the cover is open, and to penetrate deeper into the cylinder when the cover is closed. In the open state, the cylinder cover covers the upper space of the agitator, preventing both horizontal and vertical impacts. This effectively avoids the problem of the agitator being exposed too much under the cylinder cover, which could easily cause accidental damage.

[0024] Through the coordination between the baffle motor, baffle frame, trough plate, large gear, small gear, roller, and material cylinder, the output shaft of the baffle motor drives the trough plate intermittently via a crank and rod, with a transmission ratio of 4:1. Simultaneously, the trough plate can rotate synchronously with the second large gear. Subsequently, the second large gear can drive the first small gear to rotate. At the same time, the first large gear can rotate synchronously with the first small gear, which in turn drives the baffle frame to rotate by driving the second small gear. However, since the transmission ratio between the large gear and the small gear in this design is set at 1:2, when the trough plate rotates 90°, the first small gear rotates exactly half a turn, while the second small gear rotates exactly one turn, thus driving the baffle frame to rotate one turn. Combined with the rotating roller, this achieves forward conveying of the material cylinder. The baffle frame can pass through four material cylinders in one turn, effectively avoiding the problem of material cylinder replacement not being able to be automatically changed in batches or groups, resulting in excessively long intervals between multiple groups of mixing and preparation, which affects the preparation efficiency.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] See attached document Figure 1-7 In this embodiment, a preparation device for coal-based solid waste filling paste includes a processing platform 1 and a support frame 2. Multiple rollers 6 are rotatably connected to the inner left side of the processing platform 1. A bottom support 7 is provided inside the lower part of the support frame 2. A side support 11 is fixedly connected to the upper left side of the bottom support 7. Multiple material cylinders 9 are evenly distributed above the outer wall of the rollers 6. A cylinder cover 10 is provided on the upper part of the material cylinder 9. A linkage component 4 is installed on the upper part of the cylinder cover 10. A drive component 5 is installed on the upper part of the side support 11. A material blocking component 3 is installed on the lower front side of the processing platform 1. The processing platform 1 is fixedly connected to the upper end of the support frame 2. A material cylinder baffle 12 is installed on the upper right side of the processing platform 1. The material cylinder baffle 12 and the upper end of the processing platform 1 are not protruding to limit the position of the material cylinders 9. Rack supports 8 are distributed on both the front and rear sides of the left side of the outer wall of the material cylinders 9. The lower ends of the rack supports 8 are fixedly connected to the processing platform 1.

[0035] See attached document Figure 1-7 In this embodiment, the material blocking assembly 3 includes a large gear 301, a large gear 302, a crank 303, a small gear 304, a groove plate 305, a small gear 306, a bearing seat 307, a material blocking frame 308, a material blocking motor 309, and a round rod 310.

[0036] The stop frame 308 is located on the upper front right side of the processing platform 1. The lower end of the internal rotating shaft of the stop frame 308 is fixedly connected to the second pinion 306, and the outer wall of the internal rotating shaft of the stop frame 308 is rotatably connected to the processing platform 1 through the bearing seat 307. The right side of the outer wall of the second pinion 306 is meshed with the first large gear 301. The lower end of the internal rotating shaft of the first large gear 301 is fixedly connected to the first pinion 304, and the outer wall of the internal rotating shaft of the first large gear 301 is rotatably connected to the processing platform 1 through the bearing seat 307. The transmission ratio between the large gear and the pinion is set at 1:2. The stop motor... The model of 309 can be determined according to the specific application. The rear side of the outer wall of the small gear 304 is meshed with the large gear 302. The lower end of the internal shaft of the large gear 302 is fixedly connected to the slot plate 305. The outer wall of the internal shaft of the large gear 302 is rotatably connected to the processing platform 1 through the bearing seat 307. The transmission ratio between the crank 303 and the slot plate 305 is 4:1. The rear side of the outer wall of the slot plate 305 is in contact with the crank 303. A round rod 310 is fixedly connected to the upper rear end of the crank 303. The center of the upper end of the crank 303 is fixedly connected to the end of the output shaft of the feed motor 309.

[0037] Through the coordination between the baffle motor 309, the baffle frame 308, the slot plate 305, the large gear, the small gear, the roller 6, and the material cylinder 9, the output shaft of the baffle motor 309 drives the slot plate 305 intermittently via the crank 303 and the round rod 310, with a transmission ratio of 4:1. Simultaneously, the slot plate 305 can rotate synchronously with the second large gear 302. Subsequently, the second large gear 302 drives the first small gear 304 to rotate. At the same time, the first large gear 301 can rotate synchronously with the first small gear 304. Furthermore, the first large gear 301 can drive the second small gear 306 to move the baffle. The frame 308 rotates. However, since the transmission ratio between the large gear and the small gear in this case is set at 1:2, when the trough plate 305 rotates 90°, the small gear 1 304 rotates half a turn, and the small gear 2 306 rotates one turn. This drives the baffle frame 308 to rotate one turn. Combined with the rotating roller 6, the material cylinder 9 is conveyed forward. The baffle frame 308 can pass through four material cylinders 9 in one turn. This effectively avoids the problem that the material cylinders cannot be replaced in batches and automatically, which would cause the mixing and preparation interval between multiple groups to be too long and affect the preparation efficiency.

[0038] See attached document Figure 1-7 In this embodiment, the drive assembly 5 includes a fixed pulley 501, a drive motor 502, a traction rope 503, a stirrer 504, a main shaft 505, a side strip 506, a vertical cylinder 507, and a sliding platform 508.

[0039] The sliding platform 508 is slidably connected to the upper right side of the outer wall of the side bracket 11 via a slide rail. The center of the left end of the sliding platform 508 is fixedly connected to one end of the traction rope 503, and the other end of the traction rope 503 is fixedly connected to the winding roller at the end of the power source inside the side bracket 11. The model of the drive motor 502 can be determined according to the specific application. Fixed pulleys 501 are wound and connected to both sides of the upper part of the outer wall of the traction rope 503. The fixed pulleys 501 are rotatably connected to both sides of the upper inner wall of the side bracket 11. The sliding platform can be controlled by winding and unwinding the end of the traction rope 503. The sliding platform 508 slides up and down. Multiple drive motors 502 are fixedly connected at equal intervals on the right side of the outer wall of the sliding platform 508. The output shaft of the drive motor 502 is fixedly connected to the vertical cylinder 507. The main shaft 505 is intermittently fitted inside the vertical cylinder 507. A side strip 506 is fixedly connected to one side of the outer wall of the main shaft 505. The side strip 506 can realize the rotational transmission between the main shaft 505 and the vertical cylinder 507. The outer wall of the side strip 506 is slidably connected to the notch in the inner wall of the vertical cylinder 507. The lower part of the outer wall of the vertical cylinder 507 is rotatably connected to the cylinder cover 10 through a bearing. A stirrer 504 is fixedly connected to the lower end of the main shaft 505.

[0040] See attached document Figure 1-7 In this embodiment, the linkage component 4 includes a spur gear 401, an internal rack 402, a gear bracket 403, a slide rod 404, a bottom beam 405, and an external rack 406.

[0041] Multiple spur gears 401 are distributed on the front and rear sides of the upper end of the cylinder cover 10. Gear brackets 403 are rotatably connected to both sides of the shaft of the spur gear 401. The lower end of the gear bracket 403 is fixedly connected to the cylinder cover 10. The inner and outer sides of the outer wall of the spur gear 401 are meshed with an inner rack 402 and an outer rack 406 respectively. When the spur gear 401 moves downward, it can be blocked by the outer rack 406 and rotate. The outer wall of the outer rack 406 is fixedly connected to the rack bracket 8. The lower part of the outer wall of the inner rack 402 is slidably connected to the cylinder cover 10. The lower end of the inner rack 402 is fixedly connected to a bottom beam 405. The center of the inner wall of the bottom beam 405 is rotatably connected to the main shaft 505 through a bearing. The slide rod 404 is used to limit the up and down movement of the cylinder cover 10. Multiple slide rods 404 are fixedly connected to both sides of the upper end of the cylinder cover 10, and the outer wall of the slide rod 404 is slidably connected to the rack bracket 8.

[0042] Through the cooperation between the sliding platform 508, drive motor 202, cylinder cover 10, vertical cylinder 507, agitator 504, external rack 406, internal rack 402, and bottom beam 405, the sliding platform 508 drives the drive motor 502, vertical cylinder 507, and cylinder cover 10 to move downwards synchronously until the cylinder cover 10 completely covers the corresponding material cylinder 9. During this period, the spur gear 401 rotates due to the obstruction of the external rack 406 as it moves downwards with the cylinder cover 10. Simultaneously, this rotation meshes with and drives the internal rack 402 to move downwards, allowing the internal rack 402 to drive the bottom beam 405 further downwards. The bottom beam 405 moves downwards by a distance, while the cover 10 moves downwards by a distance equal to the bottom beam 405. This allows the agitator 504 to be closer to the cover 10 when the cover is open, and to be deeper inside the cylinder 9 when the cover is closed. When the agitator 504 is removed, it can be removed by moving the sliding platform 508 halfway. This effectively avoids the need to move a greater distance during the removal of the agitator to carry out the subsequent loading and unloading process, which would otherwise lead to low loading and unloading efficiency during cylinder replacement and affect the overall processing efficiency.

[0043] This design allows the agitator 504 to be closer to the cylinder cover 10 when the cover is open, and to be deeper inside the cylinder 9 when the cover is closed. In the open state, the cylinder cover 10 covers the upper space of the agitator 504, thus blocking both horizontal and upward impacts. This effectively avoids the problem of the agitator being exposed too much at the bottom of the cylinder cover, which could easily cause accidental damage.

[0044] Working principle:

[0045] This invention relates to a method for using a device for preparing coal-based solid waste filling paste. First, the user assembles the entire structure. After assembly, the roller 6 of the device is aligned with the external conveying structure. Then, the fly ash, gasification slag, bottom ash, desulfurized gypsum fine particles, and flocculant required for mixing and preparation are pre-placed inside the material cylinder 9. Subsequently, the material is piled up at the external conveying structure and transported to the mixing and preparation station of this invention. The specific mixing and preparation process is as follows:

[0046] S1: Loading Process: When loading or unloading is required, the user can control the baffle motor 309, causing the output shaft of the baffle motor 309 to drive the slotted plate 305 intermittently via the crank 303 and the round rod 310. The transmission ratio is 4:1. At the same time, the slotted plate 305 can rotate synchronously with the large gear 302. Subsequently, the large gear 302 can drive the small gear 304 to rotate. Simultaneously, the large gear 301 can rotate synchronously with the small gear 304. Furthermore, the large gear 301 can drive the small gear 304 to rotate. Wheel 2 306 drives the baffle 308 to rotate. However, since the transmission ratio between the large gear and the small gear in this case is set at 1:2, when the trough plate 305 rotates 90°, the small gear 1 304 rotates half a turn, and the small gear 2 306 rotates one turn. This drives the baffle 308 to rotate one turn. Combined with the rotating roller 6, the material cylinder 9 is conveyed forward. The baffle 308 can pass through four material cylinders 9 in one turn, thus realizing the loading and unloading process of four material cylinders 9 as a group.

[0047] S2: Linkage Process: After the replacement of the material cylinder 9 is completed, the user can control the winding roller at the end of the power source in the side bracket 11 to rotate, so that it controls the sliding platform 508 to move downward by releasing the traction rope 503. During this process, the sliding platform 508 drives the drive motor 502, the vertical cylinder 507 and the cylinder cover 10 to move downward synchronously until the cylinder cover 10 completely covers the corresponding material cylinder 9. During this period, the spur gear 401 rotates due to the obstruction of the outer rack 406 during the movement as it moves downward with the cylinder cover 10. At the same time, the rotation meshes with the inner rack 402 to move downward, so that the inner rack 402 can drive the bottom beam 405 to move further downward. That is, the cylinder cover 10 moves downward a certain distance, and the bottom beam 405 moves downward a distance equal to that distance. Thus, in the open state, the agitator 504 is closer to the position of the cylinder cover 10, and in the closed state, the agitator 504 goes deeper into the interior of the material cylinder 9 to stir, realizing the linkage process between the agitator 504 and the cylinder cover 10 during the closing and lowering process.

[0048] S3: Stirring process: After the capping operation is completed, the user can control the drive motor 502 to drive the output shaft of the drive motor 502 to rotate the vertical cylinder 507. At the same time, since the vertical cylinder 507 and the main shaft 505 are connected by the side strip 506, the main shaft 505 can move up and down on the inner wall of the vertical cylinder 507 as the bottom beam 405 moves up and down. The rotational transmission between the vertical cylinder 507 and the main shaft 505 can always be achieved through the side strip 506. After the stirrer 504 penetrates into the inside of the material cylinder 9, the output shaft of the drive motor 502 can drive the stirrer 504 to rotate through the vertical cylinder 507 and the main shaft 505 to achieve stirring and mixing preparation inside the material cylinder 9. After the preparation is completed, the sliding platform 508 is controlled to move upward, so that the cylinder cap 10 and the stirrer 504 move upward and move away from the lateral range of the material cylinder 9. The above process is repeated to complete the preparation of continuous coal-based solid waste filling paste.

[0049] S4: Technical advantages:

[0050] Compared to traditional technology, where the relative positions of the cylinder cover and the agitator are such that the agitator needs to be completely removed during repeated loading and unloading of the cylinder, this design addresses the issue of low loading and unloading efficiency during cylinder replacement. This is because the agitator typically extends further into the cylinder, requiring a greater distance to be moved before subsequent loading and unloading can proceed. Therefore, this design incorporates a linkage component 4. This allows the sliding platform 508 to drive the drive motor 502, the vertical cylinder 507, and the cylinder cover 10 to move downwards synchronously until the cylinder cover 10 completely covers the corresponding cylinder 9. During this process, the spur gear 401, moving downwards with the cylinder cover 10, is obstructed by the external rack 406, generating… The agitator rotates, and while rotating, it engages and drives the internal rack 402 to move downwards. This causes the internal rack 402 to drive the bottom beam 405 to move further downwards. That is, the cylinder cover 10 moves downwards a certain distance, and the bottom beam 405 moves downwards a distance equal to that distance. As a result, when the cover is open, the agitator 504 is closer to the position of the cylinder cover 10, and when the cover is closed, the agitator 504 is deeper into the interior of the material cylinder 9 for agitation. When the agitator 504 is removed, it can be removed by moving the sliding platform 508 halfway. This effectively avoids the problem of the agitator needing to move a greater distance to carry out the subsequent loading and unloading process, which would otherwise lead to low loading and unloading efficiency during cylinder replacement and affect the overall processing efficiency.

[0051] Meanwhile, in traditional technology, the positions of the cylinder cover and the agitator are usually far apart. That is, the cylinder cover needs to be fastened to the upper edge of the cylinder, while the agitator needs to extend into the cylinder. This results in the agitator being exposed at the bottom of the cylinder cover after it is removed, which is too long and can easily cause the agitator to be accidentally bumped and damaged. Therefore, this design incorporates a linkage component 4, which allows the agitator 504 to be closer to the cylinder cover 10 when the cover is open, and to be deeper into the cylinder 9 when the cover is closed. This ensures that when the cover is open, the cylinder cover 10 covers the upper space of the agitator 504, preventing both horizontal and upward impacts. This effectively avoids the problem of the agitator being exposed at the bottom of the cylinder cover, which can easily cause accidental damage.

[0052] Compared to traditional technologies, where batches of cylinders require manual removal and clamping after preparation, this technology prevents automated batch replacement, leading to long intervals between batches and reduced efficiency. Therefore, this design incorporates a material-stopping component 3. When loading or unloading is needed, the user controls a material-stopping motor 309. The motor's output shaft drives a slotted plate 305 intermittently via a crank 303 and a rod 310, with a transmission ratio of 4:1. Simultaneously, the slotted plate 305 rotates synchronously with a large gear 302, which in turn drives a small gear 304. The large gear 301 can rotate synchronously with the small gear 304. The large gear 301 can then drive the small gear 306 to rotate the baffle 308. However, since the transmission ratio between the large gear and the small gear in this case is set at 1:2, when the trough plate 305 rotates 90°, the small gear 304 rotates half a turn, and the small gear 306 rotates one turn. This drives the baffle 308 to rotate one turn. Combined with the rotating roller 6, the material cylinder 9 is conveyed forward. The baffle 308 can pass through four material cylinders 9 in one turn, which effectively avoids the problem that the material cylinders cannot be replaced in batches and groups automatically, resulting in a long interval between the mixing and preparation of multiple groups, which affects the preparation efficiency.

[0053] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art will understand that various changes in form and detail are possible within the scope of the claims.

4. The method of using the preparation device for coal-based solid waste backfill paste according to claim 2, characterized in that: First, the user can assemble the overall structure. After assembly, align the roller (6) of the equipment with the external conveying structure. Then, place the fly ash, gasification slag, bottom ash, desulfurized gypsum fine particles and flocculant required for mixing and preparation inside the material cylinder (9). Then, pile them on the external conveying structure and transport them to the mixing and preparation station of this case. The specific mixing and preparation process is as follows: S1: Loading process: When loading or unloading is required, the user can control the baffle motor (309), so that the output shaft of the baffle motor (309) drives the slot plate (305) to perform intermittent transmission through the crank (303) and the round rod (310), with a transmission ratio of 4:

1. At the same time, the slot plate (305) can rotate synchronously with the large gear two (302). Subsequently, the large gear two (302) can drive the small gear one (304) to rotate. At the same time, the large gear one (301) can rotate synchronously with the small gear one (304). Then, the large gear one (301) can drive the small gear one (304) to rotate. Gear 2 (306) drives the baffle (308) to rotate. However, since the transmission ratio between the large gear and the small gear in this case is set at 1:2, when the slot plate (305) rotates 90°, the small gear 1 (304) rotates half a turn, and the small gear 2 (306) rotates one turn, which can drive the baffle (308) to rotate one turn. Combined with the rotating roller (6), the material cylinder (9) is conveyed forward. The baffle (308) can pass through the four material cylinders (9) after rotating one turn, thus realizing the loading and unloading process of the four material cylinders (9) as a group. S2: Linkage Process: After the replacement of the material cylinder (9) is completed, the user can control the winding roller at the end of the power source in the side bracket (11) to rotate, so that it controls the sliding platform (508) to move downward by releasing the traction rope (503). During this process, the sliding platform (508) drives the drive motor (502), the vertical cylinder (507) and the cylinder cover (10) to move downward synchronously until the cylinder cover (10) completely covers the corresponding material cylinder (9). During this period, the spur gear (401) moves downward with the cylinder cover (10) and is subjected to the external rack (406) during the movement. The obstruction causes rotation, and the meshing drive of the internal rack (402) moves downward, so that the internal rack (402) can drive the bottom beam (405) to move further downward. That is, the cylinder cover (10) moves downward a certain distance, and the bottom beam (405) moves downward a distance equal to that distance. Thus, in the open state, the agitator (504) is closer to the cylinder cover (10), and in the closed state, the agitator (504) goes deeper into the inside of the barrel (9) to stir, realizing the linkage process between the agitator (504) and the cylinder cover (10) during the closing and lowering process. S3: Stirring Process: After completing the capping operation, the user can control the drive motor (502) to drive the output shaft of the drive motor (502) to rotate the vertical cylinder (507). At the same time, since the vertical cylinder (507) and the main shaft (505) are connected by the side strip (506), the main shaft (505) can move up and down on the inner wall of the vertical cylinder (507) as the main shaft (505) moves up and down with the bottom beam (405), and the vertical cylinder (507) and the main shaft (505) can always be stirred by the side strip (506). The rotational transmission between the two is achieved by the agitator (504) penetrating the inside of the material cylinder (9). The output shaft of the drive motor (502) can drive the agitator (504) to rotate through the vertical cylinder (507) and the main shaft (505) to achieve the mixing and preparation of the inside of the material cylinder (9). After the preparation is completed, the sliding platform (508) is controlled to move upward, so that the cylinder cover (10) and the agitator (504) move upward and get away from the lateral range of the material cylinder (9). The above process is repeated to complete the preparation of continuous coal-based solid waste filling paste.
