[0002] Gangue grouting refers to a new technology that injects grouting into the delamination layer of coal seam overburden to reduce subsidence, inhibit overburden movement, reduce surface subsidence, and can adapt to the safe mining of "three-down" compressed coal. It is based on a full study of the destruction mechanism of coal seam overburden layers. It utilizes the delamination space in the process of overburden destruction, and injects gangue slurry, fly ash slurry and other filling materials into the delamination space through ground drilling to inhibit further destruction of the overburden at the grouting layer, slow down the speed of overburden movement to the surface above it, control rock movement, and ultimately achieve the purpose of reducing surface subsidence.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] like Figures 2 to 4 As shown, an embodiment of the utility model provides a filtering device, which includes a filter box 10, a filter plate 20, a storage box 30 and a cleaning assembly 40. The filter box 10 has a accommodating chamber 11 and a first opening 12, a feed port 13 and a discharge port communicated with the accommodating chamber 11. The filter plate 20 is arranged in the accommodating chamber 11, the filter plate 20 abuts against the inner wall of the filter box 10, the first opening 12 and the feed port 13 are located above the filter plate 20, and the discharge port is located below the filter plate 20. The storage box 30 has a storage chamber 31 and a second opening that are communicated with each other, the first opening 12 and the second opening are arranged opposite to each other, the first opening 12 and the second opening are communicated with each other, and the storage chamber 31 is used to store the gangue in the slurry after filtering on the filter plate 20. The cleaning assembly 40 can drive the gangue on the filter plate 20 into the storage chamber 31 through the first opening 12 and the second opening. In the present application, the feed port 13 of the filter box 10 is connected to the box body 110 storing the slurry through the feed pipe 120, and the discharge port of the filter box 10 is connected to the grouting pipeline.

[0035] By applying the technical solution of the present application, the slurry in the box 110 is injected into the accommodating chamber 11 through the feed port 13, and filtered on the filter plate 20. The filtered slurry is discharged through the discharge port, and the cleaning component 40 drives the remaining gangue after filtration into the storage chamber 31 through the first opening 12 and the second opening. In this way, it is possible to screen out the larger particles of gangue in the slurry, thereby preventing the large particles of gangue from affecting the normal grouting filling work, thereby achieving the purpose of grouting to reduce settlement, inhibit the movement of overburden, and reduce surface subsidence, and at the same time ensure the smoothness of the slurry circulation, and avoid the slurry blocking the grouting pipeline.

[0036] like Figure 2 and Figure 3 As shown, the cleaning assembly 40 includes a scraper 41, which abuts against the upper surface of the filter plate 20, and the scraper 41 is movably arranged in the accommodating chamber 11. The scraper 41 has an initial position far away from the first opening 12 and a working position close to the first opening 12, and when the scraper 41 is in the initial position, the scraper 41 is located on the side of the feed port 13 far away from the first opening 12. Such an arrangement can ensure that the gangue can be driven into the storage chamber 31 through the first opening 12 and the second opening. Such an arrangement can scrape off the large particles of gangue on the filter plate 20. Among them, when the filter plate 20 is filtering, part of the gangue will be blocked in the filter holes of the filter plate 20, and the scraper 41 can also scrape off the gangue in the filter holes. Such an arrangement can remove the gangue on the filter plate 20 to avoid affecting the subsequent filtering work of the filter plate 20, and at the same time, the structure is simple and easy to operate.

[0037] like Figure 3 As shown, the cleaning assembly 40 also includes a driving structure 42, which is connected to the cleaning assembly 40, and the driving structure 42 can drive the scraper 41 to move between the initial position and the working position. This arrangement can improve the automation of the filtering device and facilitate the scraper 41 to clear the gangue on the filter plate 20.

[0038] Specifically, the driving structure 42 includes a connecting rod 421 and a driving member 422. The connecting rod 421 is threadedly connected to the cleaning assembly 40. The driving member 422 is drivingly connected to the connecting rod 421 to drive the connecting rod 421 to rotate, and the driving member 422 drives the scraper 41 to move through the connecting rod 421. In this way, the driving structure 42 is simple in structure and easy to operate, and at the same time, the stability of the scraper 41 during movement can be ensured.

[0039] like Figure 3 and Figure 4As shown, the filter plate 20 is tiltedly arranged in the accommodating chamber 11, and the end of the filter plate 20 close to the first opening 12 is lower than the end of the filter plate 20 away from the first opening 12. In this way, part of the gangue can also automatically roll to the first opening 12, which further facilitates the removal of the gangue on the filter plate 20. The connecting rod 421 extends in the horizontal direction. The cleaning assembly 40 also includes a guide plate 43, a slider 44, a first telescopic member 45, a connecting plate 46 and a slide bar 47. A guide groove 431 is arranged on the guide plate 43, and the distance between the connecting rod 421 and the guide groove 431 gradually increases in the direction close to the first opening 12. The slider 44 is threadedly connected to the connecting rod 421. One end of the first telescopic member 45 is connected to the slider 44, and the first telescopic member 45 can be telescoped in the vertical direction. The connecting plate 46 is connected to the scraper 41 and the other end of the first telescopic member 45. The slide bar 47 is arranged on the connecting plate 46, and the slide bar 47 is movably arranged in the guide groove 431. With such arrangement, the connection rod 421 , the guide plate 43 and the first telescopic member 45 cooperate to drive the scraper 41 to move along the extension direction of the filter plate 20 , while ensuring that the scraper 41 is always in contact with the filter plate 20 .

[0040] In the present application, the driving member 422 is located in the storage cavity 31. Since the scraper 41 gradually moves downward when moving in the direction close to the first opening 12, the distance between the connecting rod 421 and the guide groove 431 gradually increases in the direction close to the first opening 12. This arrangement facilitates the assembly of the driving structure 42.

[0041] In the present application, the first telescopic member 45 includes a first sleeve and a first telescopic rod, the first telescopic rod is movably arranged in the first sleeve, one end of the first telescopic rod away from the first sleeve is connected to the slider 44, and one end of the first sleeve away from the first telescopic rod is connected to the connecting plate 46.

[0042] like Figure 3 As shown, the filtering device further includes a blocking plate 51, which is movably arranged in the storage chamber 31. The blocking plate 51 has a blocking position for blocking the second opening and a avoidance position away from the second opening, and the blocking plate 51 can move between the blocking position and the avoidance position. With such arrangement, when it is necessary to remove the gangue, the blocking plate 51 is located at the avoidance position, and during the slurry filtering process, the blocking plate 51 is located at the blocking position, which can prevent the slurry from flowing into the storage chamber 31 during the filtering process, thereby ensuring that the slurry can be filtered normally.

[0043] Furthermore, the driving structure 42 is connected to the blocking plate 51. When the driving structure 42 drives the scraper 41 to move between the initial position and the working position, the driving structure 42 synchronously drives the blocking plate 51 to move between the blocking position and the avoidance position. When the scraper 41 is at the initial position, the blocking plate 51 is at the blocking position. When the scraper 41 is at the working position, the blocking plate 51 is at the avoidance position. This arrangement can further improve the automation of the filter device, while reducing the use of the driving structure 42, simplifying the structure of the filter device, facilitating assembly of the filter device, and facilitating operation by staff.

[0044] The filtering device further includes a second telescopic member 52, one end of which is connected to the blocking plate 51, and the other end of which is connected to the inner wall of the storage chamber 31. The second telescopic member 52 can be telescoped along the moving direction of the blocking plate 51. This arrangement can ensure the normal movement of the blocking plate 51 and prevent the blocking plate 51 from rotating. At the same time, it can ensure the stability of the blocking plate 51 during movement and prevent the blocking plate 51 from tilting during movement.

[0045] Optionally, the second telescopic member 52 may be an elastic member. In the present application, the second telescopic member 52 includes a second sleeve and a second telescopic rod, the second telescopic rod is movably disposed in the second sleeve, one end of the second telescopic rod away from the second sleeve is connected to the blocking plate 51, and one end of the second sleeve away from the second telescopic rod is connected to the inner wall of the storage chamber 31.

[0046] Furthermore, a limiting structure is provided between the accommodating cavity 11 and the slider 44 to limit the rotation of the slider 44. This arrangement can prevent the slider 44 from rotating when the connecting rod 421 drives the slider 44 to move, thereby ensuring the normal movement of the scraper 41.

[0047] Specifically, a slide groove is provided on the inner wall of the accommodating cavity 11 in the horizontal direction, and a limiting rod 53 is provided on the slider 44. The limiting rod 53 is movably provided in the slide groove, and the slide groove cooperates with the limiting rod 53 to form a limiting structure. Such a configuration is simple in structure, and it is convenient to process the slider 44 and the accommodating cavity 11, and the structure is simple and easy to assemble.

[0048] A vibrator 54 is provided at the bottom of the filter plate 20, and the vibrator 54 is drivingly connected to the filter plate 20. Such a configuration can improve the filtering efficiency of the filter plate 20, thereby increasing the speed of grouting and preventing the slurry from being blocked at the filter device.

[0049] like Figure 1As shown, another embodiment of the utility model provides a grouting filling device, which includes a box 110 and the above-mentioned filtering device, the box 110 is connected with the feed port 13 of the filtering device, and the box 110 injects slurry into the accommodating chamber 11 of the filtering device through the feed port 13. In this way, it is possible to remove large particles of gangue in the slurry, thereby preventing large particles of gangue from affecting the normal grouting filling work, thereby achieving the purpose of grouting to reduce settlement, inhibit overburden movement, and reduce surface subsidence, and at the same time ensure the smoothness of slurry circulation, and avoid slurry blocking the grouting pipeline.

[0050] Furthermore, in the present application, the filter device also includes a discharge pipe 14, one end of which is connected to the discharge port, and the other end of which is connected to the grouting pipe. This arrangement facilitates the connection between the filter device and the grouting pipe.

[0051] Among them, in order to better understand the present scheme, the specific working mode of the grouting filling device is as follows: the slurry in the box body 110 flows into the filter box 10, the filter plate 20 filters the slurry, and the filtered slurry is injected into the coal seam overburden separation layer through the discharge pipe 14 and the grouting pipe; after the filtration is completed, the driving structure 42 synchronously drives the scraper 41 and the sealing plate 51 to move, so that the scraper 41 moves from the initial position to the working position, and the sealing plate 51 moves from the sealing position to the avoidance position, and the scraper 41 drives the gangue on the filter plate 20 through the first opening 12 and the second opening into the storage chamber 31; then the driving structure 42 synchronously drives the scraper 41 and the sealing plate 51 to move, so that the scraper 41 moves from the working position to the initial position, and the sealing plate 51 moves from the avoidance position to the sealing position; and then the slurry is injected into the filter box 10, so as to carry out the grouting filling work in a cycle.
