Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for compressed air pipelines in underground mines, and particularly relates to a movable drainage device for underground air supply pipelines. Background Art

[0002] In general, there are power supply systems such as wind, water, and electricity in underground mines. Among them, the air supply system plays a crucial role in ensuring operation safety and improving production efficiency. The traditional air supply system mainly compresses surface air to the required pressure through an air compressor and transports it to the underground working face through pipelines. However, due to the temperature difference between the surface and the underground or the influence of seasonal temperature changes, condensed water is easily generated during the transportation of compressed air. This condensed water not only reduces the air supply efficiency but may also carry pollutants such as dust and oil stains, resulting in the blockage of equipment valves and pipeline valves and affecting normal production.

[0003] In response to the above problems, various solutions have been proposed in the prior art. A relatively prominent solution is a horizontal automatic water drainage device for compressed air pipelines in underground mines disclosed in the Chinese invention patent application with the publication number CN117780433A: It includes an air inlet pipe, an exhaust pipe, and a horizontal water collection cylinder. One end of the air inlet pipe is flange-connected to the upstream compressed air pipeline in the underground mine; the other end is located at the center of one end of the horizontal water collection cylinder. The water separation cavity is located directly above the top of the horizontal water collection cylinder, the air collection cavity is located above the water separation cavity, and the exhaust pipe is located above the air collection cavity; End cover I and end cover II are arranged at the left end of the horizontal water collection cylinder. The automatic water drainage mechanism is located on the left side inside the horizontal water collection cylinder. The water discharge pipe is arranged outside end cover II and is communicated with the water outlet channel of the automatic water drainage mechanism; the sewage discharge pipe is located directly below the bottom of the horizontal water collection cylinder.

[0004] However, this solution still has limitations in practical applications: The equipment of this solution has the problems of complex structure and inconvenient disassembly and assembly; there are also problems that when encountering seasonal changes or in the case of a long underground air supply pipeline in a heading development roadway, it cannot fully cover all branches, nor can it be directly applied to the branch air ducts on the working face. Especially for the working face in a long-distance development roadway with a high temperature and a large amount of condensed water in the branch air ducts, the working efficiency of drills and jumbo machines such as tunneling, support, and charging is reduced. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a movable drainage device for underground air supply pipelines, which solves the problems of complex structure and inconvenient disassembly and assembly of the equipment in the prior art; it also avoids the problem that when encountering seasonal changes or in a heading development roadway, it cannot fully cover all branches due to the long underground air supply pipeline, nor can it be directly applied to the branch air ducts on the working face.

[0006] To solve the above technical problems, the present utility model provides the following core technical solution: A movable underground air supply pipe drainage device, comprising a storage tank, an air inlet, an air outlet and a drain valve; the air inlet, the air outlet and the drain valve are all fixedly connected to and communicate with the storage tank; the air inlet is arranged on the side of the storage tank at a height one-third from the bottom, the air outlet is arranged at the top position on the side of the storage tank, and the drain valve is arranged on the bottom surface of the storage tank; it further includes a diversion device which is a spiral structure made of metal and is arranged inside the storage tank. The diversion device includes a central axis which is vertically fixed inside the storage tank, and the spiral structure part of the diversion device is movably connected to the central axis and can rotate.

[0007] Further, based on the above core technical solution, the storage tank is a closed cylindrical structure made of steel, with a height of 0.6 m, an outer diameter of 159 mm and a thickness of 4 mm. Further: The air inlet and the air outlet are made of steel pipes with a diameter of 32 mm, and are fixedly connected to the storage tank by welding. Threads are provided at the pipe orifices of the air inlet and the air outlet; A hanging handle is also arranged at the top of the storage tank. The hanging handle is made of iron and is welded and fixed inside the top edge of the storage tank. An iron ring is also arranged at the center of the hanging handle; Three support legs are also arranged at the bottom of the storage tank. The support legs are made of iron and are welded and fixed inside the bottom edge of the storage tank. A metal reinforcement cross bar is arranged between the support legs; A transparent liquid level tube is arranged outside the storage tank. Both the upper and lower ends of the liquid level tube are communicated with the inside of the storage tank through metal elbows.

[0008] Further, based on the above core technical solution, the drain valve is a DN20 gate valve and is welded and fixed on the bottom surface of the storage tank.

[0009] Further, based on the above core technical solution, the air inlet is arranged on the side of the storage tank at a distance of 20 cm from the bottom, and the air outlet is arranged on the side of the storage tank at a distance of 5 cm from the top.

[0010] In this movable underground air supply pipe drainage device, a spiral structure made of metal is used as the diversion device, which can effectively guide the flow direction of air, reduce turbulence and pressure loss, and timely block the condensed water in the air and drip it to the lower part of the storage tank, improving the drainage efficiency. The diversion device includes a central shaft, and the central shaft and the rotatable spiral structure provide a flexible diversion mechanism to better guide the air flow direction or assist in cleaning the condensed water and impurities in the pipe while minimizing the impact on air pressure. The storage tank is made of steel to meet the required strength and durability, and is suitable for withstanding the pressure and impact of the underground environment. Further limitation of the storage tank size ensures sufficient capacity and structural stability. The air inlet and outlet are made of steel pipes with a diameter of 32 mm. The strength of the steel pipes and the stability of the welding ensure the reliability of the connection. The threaded design facilitates connection with other pipe systems, such as connecting with PVC air inlet pipes, improving the versatility and disassembly convenience of the device. A hanging handle is provided at the top of the storage tank, and an iron ring is provided in the center of the hanging handle, which is convenient for manual handling and hanging placement during installation and use, improving the flexibility and efficiency of the operation. Three support legs and a metal reinforcement cross bar are provided at the bottom of the storage tank, which are convenient for placement on the ground during installation and use; the support legs and the reinforcement cross bar enhance the stability of the device, and the device can maintain balance even on uneven ground, preventing tilting or movement. The setting of the liquid level pipe provides an intuitive water level monitoring method for the storage tank, facilitating real-time observation and control of the drainage timing to avoid excessive water accumulation. The drain valve uses a DN20 gate valve, which has good sealing performance and strong durability. Welding fixation ensures the stability of the connection between the valve and the storage tank, facilitating rapid drainage. The positions of the air inlet and outlet are set so that during the air flow process, it is more convenient for the condensed water to gather at the bottom of the storage tank due to the blockage of gravity, the storage tank wall and the diversion device when the water-containing air flow passes through, improving the drainage efficiency.
