Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal mine dredging, especially to a mine sump structure. BACKGROUND

[0002] The mine sump is an indispensable facility in coal mines and other mines, mainly used for collecting and storing water discharged from the mine. The main role of this facility is to prevent safety hazards caused by mine water accumulation and to reduce the working pressure of the drainage system by adjusting the drainage volume to ensure the smooth production of the mine.

[0003] The main sump is responsible for receiving drainage from the mining working face and other areas. Since the mine water contains a large amount of coal powder, rock fragments and other solid substances, these substances are prone to sedimentation into sludge in the sump. In order to prevent these sludges from hindering the normal operation of the drainage system, a special filter device is usually installed inside the sump to intercept solid particles.

[0004] However, as the use time increases, the holes on the filter device are easily blocked by sludge, affecting its filtering effect. The traditional filter device usually uses bolts and nuts to fix it, and when it needs to be cleaned, it must be disassembled with the help of tools. This method not only has a complicated operation, but also because the filter device needs to be cleaned frequently, workers have to disassemble and assemble it frequently, which not only increases the labor intensity of workers, but also may cause the sump to be unable to operate continuously and efficiently, thereby affecting the safe production of the entire mine.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example: A mine water tank structure, such as Figures 1-2 As shown, it includes a water tank body 1, a tank roof 2, a connecting steel frame 4, a filter frame 5, bolts 6, nuts 7, a positioning block 11, an electric push rod 21 and a scraper 22. The top of the water tank body 1 is connected to the tank roof 2, and the two are interconnected. The left and right sides of the water tank body 1 are the tank bottom 3, the left side of the middle of the water tank body 1 is the first sedimentation area 8, and the right side of the middle of the water tank body 1 is the second sedimentation area 9. The first sedimentation area 8 and the second sedimentation area 9 are interconnected with the tank bottom 3 on both sides through a slope, which is conducive to the flow of sewage and silt. The position between the first sedimentation area 8 and the second sedimentation area 9 in the water tank body 1 is connected with a positioning block 11, and a connecting steel frame 4 is installed on the upper side of the middle of the tank roof 2. The connecting steel frame 4 is connected The filter frame 5 is fixedly connected by multiple bolts 6 and nuts 7. The bolts 6 and nuts 7 are set at a position away from the water surface to reduce the risk of corrosion and oxidation. The connecting steel frame 4 has sufficient strength to support the filter frame 5 and the silt load thereon. A Z-shaped slot 10 is provided at the bottom of the filter frame 5, and the top surface of the positioning block 11 fits into the Z-shaped slot 10. The two are clamped together to withstand the silt in the first sedimentation area 8, and the filter frame 5 is made of corrosion-resistant material to increase its service life. An electric push rod 21 is installed on the top of the silo roof 2, and a scraper 22 is connected to the telescopic rod of the electric push rod 21. The scraper 22 moves downward and fits closely against the left side wall of the filter frame 5 to clean the filter frame 5.

[0023] like Figure 3As shown, it also includes the limit rod 12, spring 13 and push plate 14, the right side of the connecting steel frame 4 is symmetrically connected with the limit rod 12, the limit rod 12 is slidingly connected with the push plate 14, the push plate 14 is connected with the spring 13 between the left and right sides of the connecting steel frame 4, the spring 13 is sleeved on the limit rod 12, the push plate 14 is uniformly and spacedly connected with the convex rod aligned with the hole of the filter frame 5, the convex rod is slidingly matched with the hole, the upper portion of the push plate 14 is provided with the inclined rod structure, and the scraper 22 abuts against the inclined rod.

[0024] The water inrush of each area of the whole mine is drained through the roadway and finally collected in the mine water sump body 1. The mine water flows from the left side to the right side of the water sump body 1, first flows into the first sedimentation area 8 through the left side of the sump bottom 3, the positioning block 11 is used to block the sludge in the mine water, and the filter frame 5 can further intercept the sludge, so that the mine water flows to the second sedimentation area 9 through the filter frame 5, and the sludge is deposited in the first sedimentation area 8. Through the clamping of the clamping groove 10 and the positioning block 11, the filter frame 5 can be effectively prevented from tilting or loosening to the right side due to the pushing force of the sludge. The bolt 6 and the nut 7 are arranged at a position away from the water surface, so as to avoid contact with the mine water as much as possible, thereby prolonging the service life of the bolt 6 and the nut 7. The fine particles in the mine water can pass through the filter frame 5, but since the height of the second sedimentation area 9 is lower than the sump bottom 3 on the right side, this is beneficial to the further sedimentation of the fine particles in the later period. The cleaning equipment can conveniently clean the first sedimentation area 8 and the second sedimentation area 9. If it is necessary to clean the filter frame 5, the electric push rod 21 can be started, the telescopic rod of the electric push rod 21 is extended to drive the scraper 22 to move downward. Initially, the spring 13 is in a stretched state, the scraper 22 abuts against the inclined rod on the push plate 14. After the scraper 22 moves downward, the spring 13 rebounds and resets, thereby making the push plate 14 move to the left side, and the convex rod on the push plate 14 is inserted into the hole of the filter frame 5, thereby pushing out the sludge remaining in the hole. The scraper 22 moves downward and closely abuts against the left side wall of the filter frame 5, so as to scrape the pushed-out blockage and sludge, thereby achieving the purpose of cleaning. After moving downward to the limit, the telescopic rod of the electric push rod 21 is shortened and reset to drive the scraper 22 to move upward and reset. When moving upward to contact the inclined rod, the inclined rod and the push plate 14 are pushed to move to the right side and reset. The spring 13 is stretched, and the convex rod is separated from the hole. Thus, the cleaning work is completed, and the cleanliness of the filter frame is ensured. If it is necessary to disassemble and replace the filter frame 5, only the bolt 6 and the nut 7 need to be removed, and the filter frame 5 can be disassembled and replaced.

The left side of the first sedimentation area 8 is connected with the frame body 20, the upper left side in the water sump body 1 is provided with the motor 18, the output shaft of the motor 18 is connected with the stirring frame 19, and the stirring frame 19 is located in the first sedimentation area 8.

[0026] When the sludge in the accumulated water is precipitated in the first precipitation area 8, the sludge may be solidified and adhered, the motor 18 can be started, the output shaft of the motor 18 rotates to drive the stirring frame 19 to rotate, so that the sludge in the first precipitation area 8 is stirred to avoid solidification and adhesion, and the frame body 20 can block the stirring frame 19, when the cleaning device cleans the first precipitation area 8, the cleaning suction pipe is blocked on the left side of the frame body 20, and does not directly contact the stirring frame 19, so that the sludge is conveniently and quickly cleaned.
