Description

Automatic water drainage device for gas drainage under negative pressure

Technical Field

The utility model relates to a mining operation utensil, especially a negative pressure that colliery gas was taken out and is adopted in-process and take out automatic water discharging device of gas.

Background

Traditional mining negative pressure drainage gas ware that drains, because the structure is complicated, not only the transportation is inconvenient with the installation use, moreover because adopt porous connection, lead to the gas tightness poor, the fault rate is high, the maintenance volume is big, is unfavorable for the data monitoring of gas exploitation and discharge in-process.

Disclosure of Invention

The utility model aims at providing a simple structure, small, light in weight, fault rate are low, need not to maintain, are favorable to the automatic water discharging device of gas is taken out to data monitoring's negative pressure.

The technical scheme of the utility model is accomplished in following mode, and it includes an inclosed vertical negative pressure water container, its characterized in that: the device comprises a water container, a negative pressure buffer, a gas drainage pipeline, at least one air inlet valve, a floating ball, an ejector rod, a water drain valve and an ejector pin switch, wherein the negative pressure buffer is installed at the top of the water container, the upper end of the negative pressure buffer is connected with the gas drainage pipeline, the air inlet valve is installed at the top of the water container, the floating ball is installed in the water container, the ejector rod penetrates through the floating ball in a sealing mode, the water drain valve is installed at the bottom of the water container. The floating ball is spherical or cylindrical. The water drain valve is a negative pressure switch which is matched with the bottom surface of the water drain device by an elastic rubber sealing gasket in a contact way.

The utility model discloses owing to adopt the haplopore configuration, have simple structure, small, light in weight, sealing performance is good, the fault rate is low, need not to maintain, be favorable to transportation and installation and the data monitoring of the in-process that drains.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The embodiment is described in detail by combining the attached drawings, and comprises a closed vertical negative pressure water container 5, wherein a negative pressure buffer 2 is arranged at the top of the water container, the upper end of the negative pressure buffer is connected with a gas drainage pipeline 1, at least one air inlet valve 3 is arranged on the top of the water container, a floating ball 6 is arranged in the water container, a push rod 8 is arranged on the floating ball in a sealed and penetrating mode, a water drain valve 7 is arranged at the bottom of the water container, and a thimble switch 4 which is in floating balance fit with the air inlet valve is arranged at the upper end of the push rod. The floating ball is spherical or cylindrical, and can be irregular in other shapes. The water drain valve is a negative pressure switch which is matched with the bottom surface of the water drain device by an elastic rubber sealing gasket in a contact way.

When the utility model is used, the upper end of the negative pressure buffer is connected with the gas drainage pipeline. In the process of gas drainage, when gas containing moisture passes through a negative pressure buffer, the moisture in the gas can automatically fall into the negative pressure buffer under the action of gravity and then flows into a water container, at the moment, a water drain valve and an air inlet valve are in an automatic closing state under the action of negative pressure, when water in the water container is gradually increased, the water can slowly move upwards along with a push rod and a thimble switch under the action of buoyancy of a floating ball, when the push rod moves upwards, the air inlet valve is automatically opened and the water drain valve is automatically closed at the same time, so that external air enters the negative pressure water container through the air inlet valve, when the water level in the water container rises and the internal pressure is increased to a certain degree, the water drain valve is automatically opened, and the water in the water container is automatically discharged under the action of gravity; when the water level of the water container falls to a certain degree, the floating ball and the thimble switch fall along with the water level, the air inlet valve is closed again, the water inlet valve is opened again, and the water drain valve is closed again due to the fact that the interior of the water container is in a negative pressure state. The water is discharged in an automatic intermittent manner. The water drainage device has the advantages of simple structure, good air tightness, and convenience in transportation, installation and data monitoring in the water drainage process.
