Example Embodiment

[0027] Example 1: as Figure 1 to Figure 3 As shown in the figure, the vertical pneumatic intelligent water discharger for gas extraction and drilling of the present invention includes an air inlet pipe intelligent control valve 1, a cylinder 2, a water discharger housing 3, a sealing transmission device 4, and a bracket composition 5. The air inlet pipe is intelligently controlled The valve 1 is connected with the cylinder 2 and is used to control the up and down movement of the piston of the cylinder 2; the sealing transmission device 4 is installed inside the water discharger housing 3 and connected with the cylinder 2, and the up and down movement of the piston of the cylinder 2 drives the up and down movement of the sealing transmission device 4; the bracket 5 is installed At the bottom of the water discharger housing 3, it is used to support the water discharger. The air cylinder 2 is fixed outside the water discharger housing 3, and a vent hole 6 is provided at the conn...

Example Embodiment

[0036] Embodiment 2: as Figure 5 , Image 6 , Figure 7 As shown, the difference from the first embodiment is that the bottom cone angle of the water discharger housing 3 is reduced, and the water discharger housing 3 is in the shape of a cone as a whole. When the water discharged from the borehole contains more coal slime, it is more conducive to the discharge of the liquid-solid mixed medium.

Example Embodiment

[0037] Example three: as Figure 8 , Figure 9 , Figure 10 As shown, the difference from the first embodiment is that the bottom structure of the water discharger housing 3 is changed, and the bottom is designed as a horizontal bottom. This structural design enables the water discharger to store more water, but the water discharged from the extraction borehole contains When there is a lot of coal slime, it is not conducive to slag discharge, and the water discharger is easy to accumulate slag and cause blockage. Therefore, when the water discharged from the drilling hole contains less coal slime, the water discharger of this structure can be selected.

Abstract

The invention discloses a vertical pneumatic intelligent water discharger for gas extraction and drilling and a method for using the same. Connected with the air cylinder, the transmission sealing device is installed inside the water discharger casing and connected with the air cylinder, and the bracket is installed at the bottom of the water discharger casing. Its use method: first determine the water discharge time interval of the water discharger; set the water storage and water discharge time through the intelligent control valve of the air inlet pipe; connect the water discharger to the air supply pipe and the extraction pipeline of the roadway respectively. The invention has novel design, realizes intelligent and high-efficiency water discharge of gas drainage pipelines through structural innovation, and overcomes the problems of easy blockage and low water discharge efficiency of traditional water dischargers.

Description

technical field [0001] The invention belongs to the technical field of gas drainage in coal mines, and in particular relates to a vertical pneumatic intelligent water release device for gas drainage drilling and a use method thereof. Background technique [0002] During the coal seam gas drainage process, when the coal seam is rich in water, the water in the coal seam will continuously infiltrate into the drainage borehole and flow into the drainage pipeline. In order to prevent the accumulated water from blocking the drainage pipeline, it is necessary to Install a water release device on the gas extraction pipeline to discharge the accumulated water in the gas extraction pipeline in time, otherwise it will affect the effective use of the negative pressure of the gas extraction, and even cause the drainage pipeline to be completely blocked. Commonly used slag discharge water drains are divided into manual slag discharge water drains and buoy type automatic slag discharge wat...
