Embodiment Construction
[0026] Below in conjunction with accompanying drawing, by describing embodiment, the present invention will be further described:
[0027] Such as figure 1 The shown automatic water release device includes a square water storage tank (1), and the left side of the square water storage tank (1) is provided with a water level thermometer (19), a water inlet pipe (20), and a straight-through joint (5); The water inlet pipe (20) is connected to the tee (23). The upper end of the tee (23) is provided with a balance pipe joint I (21), and the straight end of the tee (23) is provided with a sealing cover (22). The balance pipe joint I (21) Connect the balance pipe joint II (34) through the balance pipe (13); the outer end of the straight-through joint (5) is connected to the intake filter (4), and the inner end is connected to the intake joint I (6). The air intake joint I (6) is connected to the air intake joint II (35) through the air intake pipe (12);

The invention relates to a self-closed negative-pressure automatic water drainer with a slag and water outlet, the water outlet adopts a self-closed design, a stainless steel sealing cover of the water outlet closes the water outlet by the weight of the stainless steel sealing cover without depending on other external forces, and the water outlet is always kept in a closed state when a drainage system cannot normally drain water due to any reason, therefore, drilling gas cannot be discharged from the water outlet of the automatic water drainer, and safe production of mines is promoted. Due to the design of the conical connector on the lower portion of the square water storage tank, water impacts the square water storage tank due to the gravity effect in the drainage process, and coal cinder is discharged from a drainage opening at the same time. The opening adjusting screw can be adjusted to adjust the water discharge amount of the automatic water discharge device, and the problem of pipeline water accumulation caused by large water inflow of a drainage drill hole is better solved.
Description
technical field [0001] The invention relates to a gas drainage technology, in particular to a self-closing negative pressure automatic water release device for a slag discharge outlet. Background technique [0002] The problem of water accumulation in the pipeline of the gas drainage system is one of the main factors affecting the gas drainage. There is no reasonable and effective water discharge device, which will directly affect the gas drainage. There are many kinds of negative pressure automatic water release devices currently in use. However, their outlets are basically closed by negative pressure. If the following situations occur in the drainage system, it will bring unavoidable disasters to the mine. First of all, there was a sudden power failure in the drainage system, and it was impossible to manually close the water inlet valves of the negative pressure drains in each drainage tunnel in a short period of time, not to mention that the existing negative pressure aut...
