Description

Technical Field

[0001] The utility model relates to the application field of compressed air sewage discharge and water treatment in coal mines, especially an automatic sewage discharge and water treatment system applied to various devices in the coal mine underground environment. Background Technique

[0002] At present, application devices in coal mines are relatively widespread, such as air compressors, nitrogen generation devices, cooling devices, etc. Due to the relatively special environment in coal mines, being in an explosive gas environment, all kinds of electrical equipment must be products that have passed explosion-proof certification to be used. Each device applied in coal mines needs to carry out sewage discharge and water treatment, etc. Therefore, it is very important to develop a mechanical automatic drainage system suitable for use in coal mine devices. This can not only effectively ensure the effect of sewage discharge and water treatment of various devices applied in coal mines, ensure the safety of their device use, extend the service life of the equipment, but also have low use cost and convenient installation. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to overcome the above-mentioned prior art problems and provide a mechanical automatic drainage system for use in coal mine shafts with good automatic sewage discharge and water treatment effects, low cost, simple operation and convenient and safe use in coal mine shafts.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: a mechanical automatic drainage system for use in coal mine shafts, including: a gas-water separator, a main stop valve, a check valve, a Y-type filter, an automatic drain valve, and a manual drain valve. The gas-water separator has a drain port. After the compressed air passes through the gas-water separator 1, it is connected to the main stop valve through the drain port, and then passes through the check valve and is divided into two branches, namely an automatic drainage branch and a manual drainage branch. The Y-type filter is connected to the automatic drainage branch and then connected to the automatic drain valve, and the manual drainage branch is connected to the manual drain valve.

[0005] Further, the automatic drain valve is a float-type automatic drain valve.

[0006] Further, the automatic drainage system has a Y-type filter.

[0007] Further, the automatic drainage system has a check valve.

[0008] Further, the automatic drainage system is a pure mechanical automatic drainage system.

[0009] The advantages of the present utility model are as follows: The present utility model adopts a floating ball type automatic drain valve for water treatment. There is a round floating ball inside this automatic drain valve that can move up and down. The lower part is sealed as the drain port. When there is no water, the self-weight of the floating ball and the pressure press the floating ball to seal the drain port. When there is water, the floating ball rises and the water is discharged to achieve the effect of automatic drainage. The system is also equipped with a Y-shaped filter and a check valve. The whole system is a pure mechanical automatic drainage system, with stable sewage and drainage effects, low usage cost, convenient and safe operation, installation and use, and meets the usage conditions of the coal mine underground environment and other characteristics. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the whole of the present utility model.

[0011] Wherein: 1 - gas-water separator, 2 - main stop valve, 3 - check valve, 4 - Y-shaped filter, 5 - automatic drain valve, 6 - manual drain valve, 101 - drain port. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] The present utility model will be further described below in conjunction with the drawings and embodiments, but it is not a limitation of the present utility model.

[0013] See Figure 1 , a mechanical automatic drainage system for use in a mine, comprising: a gas-water separator 1, a main stop valve 2, a check valve 3, a Y-shaped filter 4, an automatic drain valve 5, and a manual drain valve 6. The gas-water separator 1 has a drain port 101. The drain port 101 of the gas-water separator is connected to the main stop valve 2, and the main stop valve 2 is connected to the check valve 3. After passing through the check valve 3, it is divided into an automatic drainage branch and a manual drainage branch. The automatic drainage branch is connected to the Y-shaped filter 4, and the Y-shaped filter 4 is connected to the automatic drain valve 5 and finally discharged. The manual drainage branch is directly discharged through the manual drain valve 6.

[0014] Further, the automatic drain valve is a floating ball type automatic drain valve.

[0015] Further, the automatic drainage system has a Y-shaped filter.

[0016] Further, the automatic drainage system has a check valve.

[0017] Further, the automatic drainage system is a pure mechanical automatic drainage system.

[0018] During use: After the compressed air comes in, it will first pass through the air-water separator 1 for air-water separation treatment. First, the moisture in the compressed air is discharged from the 101 drain port, and then it passes through the main stop valve 2 and is connected to the check valve 3 through the main stop valve 2; it is divided into two branches, namely the automatic drainage branch and the manual drainage branch. The Y-type filter 4 is connected to the automatic drainage branch and then connected to the automatic drain valve 5, and the manual drainage branch is connected to the manual drain valve 6. The system of the whole device is a pure mechanical automatic drainage system, which has the characteristics of stable sewage drainage effect, low use cost, convenient and safe operation, installation and use, and meets the use conditions in coal mines.
