Description

Technical Field

[0001] This utility model relates to the field of mining production technology, specifically to an emergency treatment device for mine backfilling and pipe blockage. Background Technology

[0002] During mining operations, the filling of underground goaf areas is prone to slurry loss of fluidity and pipeline blockage due to factors such as material handling, equipment operation, and instrumentation. If the slurry in the pipeline is not cleared and cleaned within a reasonable time, it will solidify, causing large-scale pipeline failure, resulting in excessive costs and increased labor intensity for workers. Furthermore, since surface water must be treated in one section before the next can be treated, the deeper the pipeline goes, the longer it takes for water to reach the blockage, the greater the instantaneous pressure, and the higher the safety risk for personnel handling the blockage. Therefore, it is necessary to further optimize the anti-blockage devices for filling pipelines to ensure the safety and efficiency of underground goaf filling. Utility Model Content

[0003] This invention provides an emergency treatment device for mine backfilling and pipe blockage, in order to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An emergency treatment device for mine backfilling blockage includes a main water pipe with multiple backfilling pipelines on the bottom side of the main water pipe. A connecting pipe is connected to the bottom of the main water pipe, and a ball valve is installed on the connecting pipe. The output end of the ball valve is connected to a rubber hose, which is connected to the backfilling pipelines.

[0006] Furthermore, the output end of the ball valve is connected to a short connector, which is connected to a water connector, and the water connector is connected to the hose.

[0007] Furthermore, clamps are provided between the short connector and the water connector, and between the hose and the filling pipeline.

[0008] This utility model has the following beneficial effects:

[0009] This utility model provides an emergency treatment device for blocked filling pipes in mines. It mainly consists of a connecting pipe, ball valve, water connector, hose, and short connector. By installing this device at the location of the main water pipe underground, the ball valve controls the flow of water. When a blockage occurs during filling, the device is immediately installed at the blocked filling pipe opening, and the ball valve is slowly opened. This ensures that cleaning water flows through the hose promptly and effectively, clearing and cleaning the slurry inside the filling pipe. This ensures the continuous unobstructed flow of the filling pipeline, greatly improving the safety and efficiency of filling goaf areas in mines. It solves the problem that currently, during filling goaf areas in mines, the inability to promptly clear blockages in the pipelines easily leads to pipe blockage and failure, ultimately reducing the safety and efficiency of mine filling.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1 As shown, an emergency treatment device for mine backfilling blockage includes a main water pipe 7, a plurality of backfilling pipes 8 are provided on the bottom side of the main water pipe 7, a connecting pipe 1 is connected to the bottom of the main water pipe 7, a ball valve 2 is provided on the connecting pipe 1, and a rubber hose 5 is connected to the output end of the ball valve 2. The rubber hose 5 is connected to the backfilling pipes 8.

[0015] The output end of the ball valve 2 is connected to a short connector 3, which is connected to a water connector 4, and the water connector 4 is connected to the hose 5.

[0016] Clamps 6 are installed between the short connector 3 and the water connector 4, and between the rubber hose 5 and the filling pipeline 8.

[0017] Connecting pipe 1 is a DN100*1000mm fluid pipe. One end is directly welded to the opening of the main water pipe 7, and the other end is welded with a flange. It is bolted to the flange at one end of the ball valve 2 and tightened.

[0018] Ball valve 2 is a DN100 valve used to control the on / off state of water and regulate the water flow.

[0019] The short connector 3 uses a φ108*300mm filling pipe, with a welded flange at one end for connection to ball valve 2, and a welded inner clamp at the other end for connection to water connector 4.

[0020] Water connector 4 is used to connect short connector 3 and hose 5. The hose 5 is inserted into water connector 4. The hose 5 is firmly tied to the tail of water connector 4 with wire. The excess part of the wire is tied to the brackets on both sides of the head of water connector 4 to prevent hose 5 from falling off water connector 4.

[0021] When using clamp 6 to fix short connector 3 and water connector 4, a sealing gasket should be added before using clamp 6 to fix them.

[0022] In practical use, this utility model involves installing the emergency treatment device at the position of the main water pipe 7, 30m above the filling pipeline head in each intermediate section of the underground filling borehole. Connecting pipe 1 connects the main water pipe 7 to ball valve 2, which controls the flow of water. Short connector 3 connects ball valve 2 to water connector 4, which connects short connector 3 to hose 5. Hose 5 connects water connector 4 to the blocked filling pipeline 8. Clamp 6 secures short connector 3, water connector 4, and hose 5. When a blockage occurs in the filling pipeline 8 during filling, the emergency device is immediately installed at the blocked opening. Then, ball valve 2 is slowly opened, quickly and effectively clearing and cleaning the slurry in the filling pipeline 8. This effectively reduces the labor intensity of workers, minimizes the amount of scrapped filling pipeline 8, and enables rapid recovery of the filling system, ensuring the strength of the filling body and greatly improving the safety and efficiency of filling goaf areas in underground mines. Therefore, this device has excellent practicality.
