For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0023] As shown in Figures 1-4 A mining filling drainage device, comprising a box body 1, a drain pipe 2, a feeding and stirring part 3, a support 6 and a filtering device 4. The box body 1 serves as the main structure of the whole device, the top of which is provided with the feeding and stirring part 3 for receiving and stirring the filling material; the bottom is provided with the drain pipe 2 and the support 6, the drain pipe 2 is used for discharging the filtered water, and the support 6 is used for supporting the whole device to ensure its stable operation.

[0024] The filtering device 4 is inclinedly arranged in the box body 1, and the filtering device 4 comprises a plurality of frames 41 which are inclinedly and spacedly inserted in the box body 1, and the inner surface of each frame 41 is connected with a filter screen 42, the filter holes of the filter screen 42 are sequentially reduced from top to bottom, forming a multi-stage filtering structure, which can efficiently filter different specifications of crushed slag and prevent the crushed slag from mixing into the water body, thereby ensuring the effective separation of the crushed slag and the water body.

[0025] In order to facilitate installation and replacement, each frame 41 is slidingly inserted between two support bars 43, which are symmetrically arranged on the inner side walls of the box 1. The frame 41 and the box 1 in contact therewith are connected and fixed by a plurality of positioning pins 44, ensuring the stability of the filter device during operation.

[0026] In view of the problem of silt accumulation and blockage of the filter screen 42, a moving frame 45 is arranged above each filter screen 42. The moving frame 45 is slidingly connected between the two side walls of the box 1, and the bottom end is provided with a cleaning brush 46 located on the upper surface of the filter screen 42. When the filter screen 42 needs to be cleaned, the moving frame 45 is pushed to drive the cleaning brush 46 to move on the surface of the filter screen, thereby cleaning the silt or debris remaining on the surface of the filter screen 42 and the filter holes, ensuring the effectiveness of the filter screen.

[0027] The specific sliding arrangement of the moving frame 45 is as follows: the moving frame 45 is connected with a moving block 47 on both sides, and the moving block 47 is slidingly arranged in a sliding groove 48 opened on the side wall of the box 1. The arrangement of the moving block 47 greatly facilitates the movement of the moving frame 45 and the cleaning brush 46.

[0028] As a preferred embodiment of the present embodiment, the moving block 47 extends to the upper and lower ends outside the sliding groove 48 and is connected with a limiting block 49, and the inner side of the limiting block 49 is tightly attached to the outer wall of the box 1. The limiting block 49 can limit the position of the moving block 47 on the inner surface of the box 1, prevent excessive sliding, and ensure the stability and safety of the cleaning process.

[0029] As a preferred embodiment of the present embodiment, as shown in Figures 5-6 The two outer sides of the box 1 are provided with a blocking device 5 for limiting the sliding of the moving block 47 when needed, ensuring the normal filtering operation of the filter screen 42. The blocking device 5 includes two fixed blocks 51 connected to the side walls of the box 1, and a rotating rod 52 is rotatably connected between the two fixed blocks 51, and the rotating rod 52 is located on one side of the moving block 47, limiting the moving block 47. Two insertion blocks 53 are also inserted into the two fixed blocks 51, and the two insertion blocks 53 are located on both sides of the rotating rod 52, limiting the rotating rod 52.

[0030] When the sliding of the moving block 47 needs to be limited, the two insertion blocks 53 are inserted into the two fixed blocks 51, and the insertion blocks 53 can limit the rotation of the rotating rod 52, so that the rotating rod 52 limits the sliding of the moving block 47. When the filter screen 42 needs to be cleaned, the two insertion blocks 53 in the two fixed blocks 51 are pulled out, and the rotating rod 52 can rotate, thereby releasing the limitation of the moving block 47, and the moving block 47 can slide freely for cleaning the filter screen 42.

[0031] As a further preferred embodiment of the present embodiment, one end of the two insertion blocks 53 is connected with a connecting block 54, the connecting block 54 is arranged to be magnetically attracted to the side wall of the fixed block 51, so as to facilitate the insertion and removal of the insertion block.

[0032] Working principle: during the drainage of the filling material, the filling material is transferred to the feeding and stirring part 3, and the filling material will fall on the multi-layer filter screen 42 in turn. After the step-by-step filtration of the multi-layer filter screen, the debris is intercepted by the filter screen 42 and slides along the surface of the filter screen to be discharged, and the separated water falls into the bottom of the box body 1 through the filter holes of the filter screen 42, and is finally discharged through the drain pipe 2, so as to realize the efficient drainage of the filling material.

[0033] When the filter screen 42 surface appears mud attachment or gravel blockage of filter holes, by pulling the handle 55, the connecting block 54 and the two insertion blocks 53 are moved out of the two fixed blocks 51, and the restriction of the insertion block 53 on the rotating rod 52 is released. Then the rotating rod 52 is rotated upward, so that the rotating rod 52 is away from the moving block 47, and the restriction of the rotating rod 52 on the moving block 47 is released. At this time, the moving block 47 can be pushed at will to slide in the chute 48, so as to drive the moving frame 45 and the cleaning brush 46 at the bottom end of the moving frame 45 to slide on the surface of the filter screen 42, and clean the residual mud or debris in the filter holes of the filter screen 42, so as to restore the effectiveness of the filter screen.

[0034] After the filter screen 42 is cleaned, the moving block 47 is pushed to move the cleaning brush 46 to the rear end of the filter screen 42 (i.e. the inclined high position), the rotating rod 52 is rotated downward, so that the rotating rod 52 is close to the moving block 47, and then the two insertion blocks 53 are inserted into the two fixed blocks 51. At this time, the insertion block 53 can restrict the rotation of the rotating rod 52, and the rotating rod 52 can restrict the movement of the moving block 47, so as to prevent the sliding of the moving block 47 from affecting the filtration operation of the filter screen 42.

[0035] The present application has been described in detail by specific and preferred embodiments, but those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and any modification, equivalent replacement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
