[0002] The main function of the coal mine compressed air system is to provide sufficient compressed air to the inside of the mine to ensure the safety and efficiency of underground operations, reduce the underground temperature, dilute harmful gases, improve the air quality of the working environment, and thus reduce the probability of accidents. The compressed air system plays a major role in coal mine safety production and is one of the six major emergency systems in coal mines. However, the compressed air transported by the compressed air pipeline often contains water, and the use of the sprayed slurry will be affected after the water-containing compressed air is introduced into the shotcreting machine.

Content of the Utility Model

[0003] The purpose of the utility model is to provide a compressed air water drainage bag to solve the problem that the use of the sprayed slurry is affected due to water in the compressed air.

[0005] The compressed air water drainage bag includes a hollow cylinder with its central axis arranged horizontally, both ends of the hollow cylinder are closed, an air inlet pipe and a drain pipe are communicatively arranged on one end face of the cylinder, and an air outlet pipe is communicatively arranged vertically upward on the circumferential surface of the cylinder; the diameter of the cylinder is 4-5 times the diameter of the air inlet pipe; the length of the cylinder is 8-10 times the diameter of the air inlet pipe;

[0006] Among them, the air inlet pipe is used to communicate with the high-pressure hose in the compressed air pipeline to introduce compressed air, and the water in the compressed air deposits at the bottom of the cylinder; the drain pipe is used to discharge the deposited water; the air outlet pipe is used to communicate with the high-pressure hose of the shotcreting pipe.

[0007] Further, the drain pipe is located at a position close to the bottom of the cylinder, and the air inlet pipe is located at a position close to the center of the cylinder.

[0008] Further, a valve is arranged on the drain pipe.

[0009] The beneficial effect of the utility model is: a compressed air water drainage bag is installed on the compressed air pipeline. Through the compressed air water drainage bag, the water in the compressed air is removed, ensuring the normal use of the compressed air and not affecting the sprayed slurry. The structure of the compressed air water drainage bag is simple, the use method is convenient, the cost is low, and the maintenance cost is low. It is more practical when there is water in the compressed air during shotcreting.

Specific Embodiment

[0012] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] The present utility model provides a compressed air water drainage package, based on a compressed air pipeline, the compressed air pipeline includes a 4-inch welded pipe, and the welded pipe is connected to a high-pressure hose. As Figure 1 shown, the compressed air water drainage package includes a hollow cylinder body 1 with its axis arranged horizontally. Both ends of the hollow cylinder body 1 are closed. An air inlet pipe 3 and a drain pipe 4 are connected and arranged on one end face of the cylinder body 1, and an air outlet pipe 2 is vertically and upwardly connected and arranged on the circumferential surface of the cylinder body 1. Under normal circumstances, air moves upward, so the air outlet pipe 2 is arranged above with an upward opening.

[0014] The diameter of the cylinder body 1 is 4 to 5 times the diameter of the air inlet pipe; the length of the cylinder body 1 is 8 - 10 times the diameter of the air inlet pipe. For example, in actual use, an 8-inch round pipe can be used as the cylinder body 1. The outer diameter of the 8-inch round pipe is about 203.2 mm, and the length of the cylinder body 1 is 500 mm. Both the air inlet pipe 3 and the air outlet pipe 2 are round pipes, and the outer diameters of both the air inlet pipe 3 and the air outlet pipe 2 are 39 mm. The relatively thick cylinder design is more conducive to collecting water in the compressed air.

[0015] Among them, the air inlet pipe 3 is used to be connected to the hose in the compressed air pipeline to introduce compressed air, and the water in the compressed air deposits at the bottom of the cylinder body 1; the cylinder body 1 is used to collect the water in the compressed air; the drain pipe 4 is used to drain the water deposited at the bottom of the cylinder body 1; the air outlet pipe 2 is used to be connected to the high-pressure hose of the shotcreting pipe and export the dried compressed air.

[0016] The 4-inch welded pipe in the compressed air pipeline is connected to the high-pressure hose through a tee. The high-pressure hose is connected to the air inlet pipe 3, and the compressed air is introduced into the interior of the cylinder body 1 from the air inlet pipe 3. Due to the self-weight of water, the water in the compressed air falls and deposits at the bottom of the cylinder body 1 to achieve the drying treatment of the compressed air. The air outlet pipe 2 is connected to the shotcreting pipe of the shotcreting machine through a high-pressure hose, and the compressed air can normally pass through the high-pressure hose, the air inlet pipe 3, the interior of the cylinder body 1 and finally flow out from the air outlet pipe 2 and reach the shotcreting pipe.

[0017] In some embodiments, the drain pipe 4 is located near the bottom of the cylinder body 1, and the air inlet pipe 3 is located near the center of the cylinder body 1. The drain pipe 4 is used to drain the water deposited at the bottom of the cylinder body 1, so it is beneficial for drainage to set the drain pipe at a lower position. The air inlet pipe 3 is set at the center position, which is beneficial for the compressed air to evenly pass through the cylinder body 1.

[0018] In some embodiments, a valve is provided on the drain pipe 4. By providing the valve, the valve can be opened when needed to discharge the collected water, and the valve can also be closed when needed to collect the water in the compressed air into the cylinder body 1.

[0019] The usage method of the compressed air water drainage package is as follows:

[0020] The compressed air transmitted through the high-pressure hose of the compressed air pipeline is introduced into the interior of the cylinder body 1 from the air inlet pipe 3;

[0021] The compressed air passes through the interior of the cylinder body 1 and finally flows out from the upper air outlet pipe 2 and reaches the shotcrete pipe;

[0022] During the process of the compressed air flowing out, the water in the compressed air falls and deposits at the bottom of the cylinder body 1, and finally the dehydration effect of the compressed air is achieved, which not only ensures the normal use of the compressed air, but also does not affect the proportion of the shotcrete due to excessive moisture, and thus does not affect the setting and shotcreting effect of the slurry.
