Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 4, the automatic drainage and deslagging device for a coal mine gas extraction pipeline in the prior art has the following working states:

and closing the air inlet valve (6) and the water and slag discharging valve (8), opening the inlet valve (3), and pumping accumulated water and coal slag in the running process of the pipeline into the sedimentation tank through the water inlet and slag leakage branch pipe (2) under the action of gravity.

And (3) drainage and slag discharge processes: and closing the inlet valve (3), opening the air inlet valve (6), and then opening the drainage and slag discharge valve (8), wherein the air inlet valve (6) is communicated with the outside air, and water and coal slag deposited in the deposition box are discharged through the drainage and slag discharge valve (8) under the action of gravity, so that the purposes of depositing and discharging accumulated water and coal slag in the extraction pipeline are achieved.

Embodiment 1, refer to fig. 1-3, the utility model provides an online automatic drainage and slag discharge device for a coal mine gas extraction pipeline, in extracting pipeline series connection deposit box 10, the same bore is adopted with former extraction pipeline in the air inlet, the export of giving vent to anger and the outlet of deposit box 10, the inlet end is connected with a downward elbow of opening in deposit box 10, the downward elbow of opening is connected with intake pipe 12;

the outlet end is connected with an upward-opening elbow in the deposition box 10, and the upward-opening elbow is connected with an exhaust pipe 13 to ensure the complete deposition of impurities.

The bottom of the settling tank 10 is designed to be tapered, and the water outlet and the air inlet are designed to have the same caliber, so that the deposited impurities can be smoothly discharged.

Including deposit case 10, intake pipe 12, blast pipe 13, drain pipe 14 and bypass pipe 15, intake pipe 12 and blast pipe 13 respectively with deposit case 10 top both sides outer wall intercommunication, drain pipe 15 installs in deposit case 10 bottom, bypass pipe 15 both ends respectively with intake pipe 12 and blast pipe 13 intercommunication, be fixed with shower 6 on the deposit case 10 inner wall, and shower 6's bottom installs the shower head 7 that the equidistance distributes.
