Description

An automatic water discharge device for a compressed air pipeline

technical field

The utility model relates to a coal mine underground drainage device, in particular to an automatic water drainage device for a compressed air pipeline.

Background technique

With the continuous extension of the mine production level, the input amount of the compressed air pipeline will gradually increase. Since the exhaust temperature of the compressor is about 50 °C, the downhole temperature is generally around 23 °C, and the temperature difference between the upper and lower wells is large, which causes the gas to liquefy seriously on the inner wall of the compressed air pipeline, and it is easy to accumulate a large amount of water at the low-lying points of the pipeline. As a result, the air pressure resistance in the pipeline is increased, resulting in abnormal use of pneumatic equipment and diaphragm pumps, seriously affecting the normal circulation of the mine, and burying certain hidden dangers for the safe production of the mine.

Since there are many pneumatic equipment used in coal mines, the efficient production of coal mines can only be guaranteed if the air pressure in the compressed air pipeline is stable. At present, the method of discharging the accumulated water in the compressed air pipeline underground is to install the water accumulation device to manually discharge the water, and to use the maintenance time to stop the compressed air and disassemble the pipeline to release the water. This method is time-consuming and labor-intensive, and poses a certain safety hazard during operation.

In order to solve the problem that manual water discharge is time-consuming and labor-intensive in the current mine pressure air system, an automatic water discharge device is developed to automatically remove the accumulated water in the pipeline and reduce manual input.

SUMMARY OF THE INVENTION

The purpose of the utility model is to provide an automatic water discharge device for the compressed air pipeline, which can automatically discharge the accumulated water in the compressed air pipeline and ensure the efficient operation of various types of pneumatic equipment in the coal mine.

The utility model is achieved through the following technical solutions:

A fully automatic water discharge device for a compressed air pipeline, comprising a water storage tank and a pneumatic controller, the pneumatic controller is arranged on the top of the water storage tank, and an air inlet is arranged on the upper side wall of the water storage tank The lower side wall is connected with a water outlet pipe, the inside of the box is provided with a float that is sleeved on the guide rod, the air inlet pipe is connected with a water accumulation pipe connected to the water tank, and the water accumulation pipe is provided with The first pneumatic control valve and the second pneumatic control valve are arranged on the water outlet pipe, and the pneumatic controller is electrically connected with the first pneumatic control valve and the second pneumatic control valve.

Further, the position of the water storage pipe is lower than the position of the air inlet pipe, that is, a connection port is provided at the lower position of the air inlet pipe to connect with the water storage pipe.

The guide rod is vertically fixed in the middle of the water tank, and the float is sleeved on the guide rod. When the float rises to the top of the guide rod, it will touch the wind controller, that is, when the water volume increases and the water level rises , the float starts to rise, and when the float rises to a certain height, the pneumatic controller is triggered, the pneumatic controller controls the first pneumatic control valve to close, the second pneumatic control valve is opened, and the accumulated water in the water tank is discharged to the After the outside of the box, the float descends to disconnect the contact with the pneumatic controller. At this time, the first pneumatic control valve opens and the second pneumatic control valve closes; effect.

The water storage tank is a sealed box body with a "convex" structure, and the air inlet pipes are arranged on both sides of the upper part of the water storage tank.

During specific use, there is no accumulated water in the water storage tank of the utility model, or when the accumulated water is small, the float is located in the middle and lower part of the water storage tank and does not touch the pneumatic controller. At this time, the first pneumatic control valve is opened and the second The second pneumatic control valve is closed, the water in the air inlet pipe enters the water tank through the water pipe lower than the air inlet pipe, and the float starts to rise along the guide rod with the increase of the water. When it is raised to the specified position, touch the switch in the pneumatic controller. At this time, the pneumatic controller controls the first pneumatic control valve to close, the second pneumatic control valve to open, and the accumulated water in the box is discharged to the outside of the box. When the water level drops and the float descends along the guide rod, the first pneumatic controller controls the pneumatic control valve to open and the second pneumatic control valve to close, and so on, to discharge the accumulated water in the air duct.

Compared with the prior art, the utility model has the following advantages:

1), the previous manual manual water discharge is reformed into automatic water discharge;

2) Reduce the manpower input, and adjust the manpower input of manual drainage to regular personnel inspection and maintenance;

3) It avoids the accumulation of water in the pipeline due to untimely drainage, reduces the number of times of stopping pressure air operations, and ensures efficient production;

4), the structure is simple, the installation is convenient, and there is no need to energize.

To sum up, the utility model has a simple structure, is easy to popularize, can save manpower and improve work efficiency.
