Abstract
The invention belongs to the field of coal mine gas pumping pipeline drainage and relates to a negative pressure automatic water drainage device used for gas pumping pipes. The negative pressure automatic water drainage device used for gas pumping pipes comprises a gas pumping pipeline, a water inlet pipe connected with the gas pumping pipeline and a water drainage tank, the top of the water drainage tank is provided with a water inlet, a water inlet pipe is connected with the water drainage tank though the water inlet, a ball valve is arranged in the water inlet, and the lower portion of the water drainage tank is further provided with a slag-drip opening. A water drainage pipeline not higher than the water drainage tank is communicated with the water drainage tank in U-type, and a hinge pin at the tail end of the water drainage pipeline is connected with a blocking cover. The negative pressure automatic water drainage device used for gas pumping pipes is simple in structure, designed through a plurality of experiments, practical, convenient, and good in water drainage effect.
Description
Technical field
The invention belongs to coal mine gas pump drainage pipe drainage field.
Background technology
The a large amount of waste water of frequent in the fire damp pump drainage pipeline, ducted waste water can affect the pump drainage effect of pump drainage pipeline, is very unsafe, I through for many years experimental summary designed a kind of dewatering installation that overcomes this problem.
Summary of the invention
The purpose of this invention is to provide a kind of negative pressure automatic drainage device for gas drainage pipe, solve the problem of coal mine gas pump drainage pipeline internal water accumulation, filled up national blank.
Technical scheme of the present invention is: the negative pressure automatic drainage device that is used for gas drainage pipe, comprise the gas exhaust pipeline, be connected to the water inlet pipe on the gas exhaust pipeline, also comprise a delivery box, described delivery box top is provided with a water inlet, water inlet pipe is connected with delivery box by water inlet, a ball valve is installed in water inlet, described delivery box bottom also is provided with a slag-drip opening, a drainage pipe that is not higher than delivery box, described drainage pipe become U-shaped UNICOM to arrange with delivery box.
The terminal bearing pin of drainage pipe is connected with a door.
When the gas exhaust pipeline carries out the pump drainage operation, water in the boring and slag are because the effect of negative pressure enters delivery box by water inlet pipe, slag is discharged by the slag-drip opening of delivery box, because the U-shaped UNICOM of drainage pipe and delivery box arranges, after the water level in the delivery box was higher than drainage pipe, water was discharged from drainage pipe automatically, otherwise when the delivery box water level is lower than drainage pipe, because the effect of negative pressure, the door that is installed in the drainage pipe end can suck sealing automatically, plays the effect of anti feedback.
The present invention is simple in structure, and I sum up through many experiments and design, and repeatedly obtains the technological progress prize on the ore deposit, and practical and convenient, drainage effect is good.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of negative pressure automatic drainage device for gas drainage pipe of the present invention, comprise gas exhaust pipeline 1, be connected to the water inlet pipe 2 on the gas exhaust pipeline 1, also comprise a delivery box 3, delivery box 3 tops are provided with a water inlet 31, water inlet pipe 2 is connected with delivery box 3 by water inlet 31, a ball valve 32 is installed in water inlet 31, delivery box 3 bottoms also are provided with a slag-drip opening 33, a drainage pipe 34 that is not higher than delivery box 3 and arranges with delivery box 3U type UNICOM, drainage pipe 34 terminal bearing pins are connected with a door 35.
