Technical Field

[0001] This utility model belongs to the field of coal mining technology, specifically a mining backfilling and drainage device. Background Technology

[0002] In coal mine backfilling mining technology, backfilling drainage is the core link to ensure the strength of the backfill and the safety of the mining area. After the backfill material is injected into the goaf, excess water needs to be quickly discharged through the drainage device in order to achieve the consolidation and shaping of the backfill.

[0003] Chinese patent CN219209645U discloses a mining backfill drainage device, comprising a tank and a drainage box. The tank has a sealing cover on top, and a drive motor is fixedly mounted on the top of the sealing cover by screws. An agitation chamber is located inside the tank. A hydraulic rod is fixedly mounted on the top right end of the drainage box, and a water outlet pipe is fixedly mounted on the rear side of the drainage box. Support columns are fixedly mounted at the bottom corners of the drainage box, and fixing sleeves are fitted onto the outer sides of the support columns. Shock-absorbing dampers are fixedly mounted at the bottom inner ends of the fixing sleeves, and shock-absorbing springs are fitted onto the outer sides of the shock-absorbing dampers. A drainage mechanism is provided inside the drainage box. By incorporating this drainage mechanism in the mining backfill drainage device, the drainage effect of the backfill material is improved, effectively reducing filter plate clogging and increasing the device's working efficiency.

[0004] Although the aforementioned drainage device effectively improves the drainage effect of the filling material and alleviates the filter plate clogging problem to a certain extent by setting up a drainage mechanism, thereby improving work efficiency, the filter plate cleaning process is inconvenient. Once the filter plate pores become clogged, it will not only reduce the drainage effect and work efficiency, but also increase the difficulty and cost of equipment maintenance, ultimately affecting the continuity of mining operations and overall benefits. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a mining backfilling and drainage device to solve the inconvenience of the filter plate cleaning process in the prior art. Once the filter plate pores become clogged, it will not only reduce the drainage effect and work efficiency, but also increase the difficulty and cost of equipment maintenance, ultimately affecting the continuity of mining operations and overall efficiency.

[0006] A mining backfill drainage device includes: a drainage mechanism, including a drainage tank assembly and a V-shaped filter screen embedded in the drainage tank assembly;

[0007] The material cylinder mechanism includes a material cylinder assembly rotatably connected to the drain tank assembly, a stirring assembly mounted on the material cylinder assembly, and a hydraulic cylinder for driving the stirring assembly to lift and lower.

[0008] Hydraulic cylinder two is used to drive the rotation of the barrel assembly.

[0009] Preferably, the drain tank assembly includes a drain tank body, a support groove on the top of the drain tank body, an inclined drain cavity inside the drain tank body, a support ring fixedly connected to the drain tank body between the support groove and the inclined drain cavity, a water outlet pipe fixedly connected to the outside of the drain tank body, the water outlet pipe communicating with the inclined drain cavity, a shaft bracket and a rotating shaft fixedly connected to the drain tank body, a V-shaped filter screen embedded in the drain tank body, and the support ring supporting the V-shaped filter screen.

[0010] Preferably, the material cylinder assembly includes a material cylinder body, the bottom of which has a plurality of water-permeable holes, the diameter of which is smaller than the minimum particle size of the filling material particles, a rotating block is fixedly connected to one side of the material cylinder body near the bottom, the rotating block is rotatably connected to the outside of the rotating shaft, the material cylinder body is rotatably connected to the drain tank body through the rotating block, a shaft bracket is fixedly connected to one side of the outside of the material cylinder body, and a support block is fixedly connected to the other side of the outside of the material cylinder body.

[0011] Preferably, one end of the second hydraulic cylinder is rotatably connected to the first shaft bracket, and the other end of the second hydraulic cylinder is rotatably connected to the second shaft bracket.

[0012] Preferably, the stirring assembly includes a sealing cap that is snapped into the top of the barrel body, a connecting block is fixedly connected to one side of the sealing cap, a motor is fixedly connected to the top of the sealing cap, the output end of the motor passes through the sealing cap and is fixedly connected to a stirring shaft, and a V-shaped stirring paddle is fixedly connected to the outside of the stirring shaft.

[0013] Preferably, one end of the hydraulic cylinder is fixedly connected to the support block, and the other end of the hydraulic cylinder is fixedly connected to the connecting block.

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

[0015] 1. This utility model allows for convenient cleaning of the permeable holes at the bottom of the material cylinder body through its flipping action. As the material cylinder body flips, the permeable holes, which were originally located at the bottom, face upwards, allowing operators to easily inspect and clean them, removing impurities and particles that may clog the holes, ensuring the permeable holes are unobstructed, and preparing for the next round of filling and draining operations. In addition, the V-shaped filter screen design increases the filtration area, which can more effectively intercept fine particles and impurities in the filling material and prevent them from entering the draining system. The V-shaped filter screen is installed on the drain tank body in a snap-fit ​​manner, and can be easily removed for cleaning when needed.

[0016] 2. This utility model starts the motor, and the output end of the motor drives the stirring shaft to rotate, which in turn causes the V-shaped stirring paddle fixed to the outside of the stirring shaft to rotate. The rotation of the V-shaped stirring paddle stirs the filling material inside the material cylinder. This stirring action can fully release the moisture inside the filling material. In addition, during the stirring process, the mutual friction and collision between the filling material particles helps to further separate the moisture between the particles, making it easier for them to be discharged through the permeable holes. The special shape design of the V-shaped stirring paddle can reduce the resistance encountered during the stirring process when moving downwards, making the stirring smoother and more efficient, ensuring that the filling material is fully and evenly stirred, improving the drainage effect, shortening the overall drainage time, and improving the filling efficiency.

Detailed Implementation

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

[0023] like Figures 1 to 4 As shown:

[0024] Example 1: This utility model provides a mining backfill drainage device, including: a drainage mechanism 1, including a drainage tank assembly 11, and a V-shaped filter screen 12 embedded in the drainage tank assembly 11;

[0025] The material cylinder mechanism 2 includes a material cylinder assembly 21 rotatably connected to the drain tank assembly 11, a stirring assembly 22 mounted on the material cylinder assembly 21, and a hydraulic cylinder 23 for driving the stirring assembly 22 to lift.

[0026] Hydraulic cylinder 23 is used to drive the rotation of the barrel assembly 21.

[0027] Specifically, the drain tank assembly 11 includes a drain tank body 111, a support groove 112 is provided on the top of the drain tank body 111, an inclined drain cavity 113 is provided inside the drain tank body 111, a support ring is fixedly connected to the drain tank body 111 between the support groove 112 and the inclined drain cavity 113, an outlet pipe 114 is fixedly connected to the outside of the drain tank body 111, the outlet pipe 114 is connected to the inclined drain cavity 113, a shaft bracket 115 and a rotating shaft 116 are also fixedly connected to the drain tank body 111, a V-shaped filter screen 12 is embedded in the drain tank body 111, and the support ring is used to support the V-shaped filter screen 12.

[0028] Specifically, the material cylinder assembly 21 includes a material cylinder body 211. The bottom of the material cylinder body 211 has several water-permeable holes. The diameter of the water-permeable holes is smaller than the minimum particle size of the filling material. A rotating block 212 is fixedly connected to one side of the material cylinder body 211 near the bottom. The rotating block 212 is rotatably connected to the outside of the rotating shaft 116. The material cylinder body 211 is rotatably connected to the drain tank body 111 through the rotating block 212. A shaft bracket 213 is fixedly connected to one side of the outside of the material cylinder body 211. A support block 214 is fixedly connected to the other side of the outside of the material cylinder body 211.

[0029] Specifically, one end of hydraulic cylinder 2 3 is rotatably connected to shaft bracket 115, and the other end of hydraulic cylinder 2 3 is rotatably connected to shaft bracket 213.

[0030] As can be seen from the above, during use, the prepared filling material is poured evenly into the inside of the material cylinder body 211 through the opening at the top of the material cylinder body 211. After the filling material is added, the material cylinder body 211 is temporarily left to stand. Under the action of gravity, the water in the filling material will gradually pass through the water permeable holes at the bottom of the material cylinder body 211 and then be filtered through the V-shaped filter screen 12. The design of the V-shaped filter screen 12 increases the filtration area, which can more effectively intercept fine particles and impurities in the filling material, prevent them from entering the drainage system, and ensure the cleanliness of the drainage water. After filtration The water flows into the inclined drainage chamber 113 inside the drainage tank body 111 and is discharged outside the device through the outlet pipe 114, realizing the initial drainage process, reducing the moisture content of the filling material, and creating favorable conditions for subsequent operations. After the drainage is completed, the hydraulic cylinder 23 is activated. When the hydraulic cylinder 23 extends and retracts, it drives the shaft bracket 213 to rotate, thereby driving the material cylinder assembly 21 to rotate around the rotating shaft 116. Under the drive of the hydraulic cylinder 23, the material cylinder body 211 rotates around the rotating shaft 116 through the rotating block 212, so that the filling material after drainage is subjected to gravity. The filling material is poured out from the main body 211, completing the filling operation. At this time, the operator can guide the filling material to the designated filling area, such as the goaf in the mining tunnel, to effectively fill the goaf and provide safety for subsequent mining operations, preventing safety accidents such as roof collapse. While pouring out the filling material, the water permeable holes at the bottom of the main body 211 can be easily cleaned by using the flipping action of the main body 211. Because the main body 211 has been flipped, the water permeable holes that were originally located at the bottom are facing upwards, making it easy for the operator to clean them. Inspect and clean the permeable holes to remove impurities and particles that may clog them, ensuring unobstructed flow and preparing for the next round of filling and draining operations. In addition, since the V-shaped filter screen 12 is installed on the drain tank body 111 in a snap-fit ​​manner, it can be easily removed when cleaning is required. After removal, the V-shaped filter screen 12 can be cleaned centrally to remove impurities and particles attached to its surface, restore the filter screen's filtering performance, ensure the smooth progress of subsequent draining processes, extend the service life of the device, and improve overall work efficiency.

[0031] Example 2: This example is basically the same as the previous example, except that the stirring assembly 22 includes a sealing cover 221 that is embedded in the top of the barrel body 211, a connecting block 222 is fixedly connected to one side of the sealing cover 221, a motor 223 is fixedly connected to the top of the sealing cover 221, the output end of the motor 223 passes through the sealing cover 221 and is fixedly connected to a stirring shaft 224, and a V-shaped stirring paddle 225 is fixedly connected to the outside of the stirring shaft 224.

[0032] Specifically, one end of hydraulic cylinder 23 is fixedly connected to support block 214, and the other end of hydraulic cylinder 23 is fixedly connected to connecting block 222.

[0033] As can be seen from the above, if a small amount of water is found to be discharged after a period of initial settling and drainage, it indicates that there may be hidden water inside the filling material that is not easy to drain. At this time, the motor 223 is started. The output end of the motor 223 drives the stirring shaft 224 to rotate, which in turn causes the V-shaped stirring paddle 225 fixedly connected to the outside of the stirring shaft 224 to rotate. The rotation of the V-shaped stirring paddle 225 stirs the filling material inside the barrel body 211. This stirring action can fully release the water inside the filling material. In addition, during the stirring process, the mutual friction and collision between the filling material particles helps to further separate the water between the particles, making it easier for them to be discharged through the permeable holes. The special shape design of the V-shaped stirring paddle 225 can reduce the resistance encountered during the stirring process when moving downwards, making the stirring smoother and more efficient, ensuring that the filling material is fully and evenly stirred, improving the drainage effect, shortening the overall drainage time, and improving the filling efficiency.
