Abstract
The utility model relates to a gas pipeline deslagging device, which comprise a T-joint deslagging device arranged on a gas pipeline, wherein the gas outlet end of the T-joint deslagging device is provided with a filter screen; the deslagging hole of the T-joint deslagging device is enclosed by using a blind plate; a valve A and a valve B are arranged at the gas inlet end and the gas outlet end of the T-joint deslagging device respectively; upper bridge devices are arranged at the gas inlet end of the valve A and the gas outlet end of the valve B; the upper bridge devices are provided with valves C; and a pressure sensor is arranged on the filter screen on the gas pipeline. During deslagging, a valve on an upper bridge pipeline is opened, and the two valves on the gas pipeline are closed, so that gas passes through the bridge pipeline; and the blind plate in the deslagging hole of the T-joint deslagging device is opened for clearing sundries, and an original state is recovered. The gas pipeline deslagging device has the advantages of simple structure, low manufacturing cost, convenience in monitoring, capability of deslagging without halting, and improvement on the safety of construction under gas mines.
Description
Technical field
The utility model relates to the drawing-off gas technology, particularly a kind of gas pipeline deslagging device.
Background technology
The mining face under mine gas pipeline, because extraction pump negative pressure is big, long-time use often causes problems such as " pipeline blockage, pump drainage are not smooth ", need the interior foreign material of cleaning pipeline in time, but because the mixed and disorderly substances in pipe confusion is difficult for focusing on, needs termination of pumping to tear gas pipeline open in addition when handling foreign material and remove the gred, cause the repair time long, both influenced working surface production, waste of manpower again, material resources, repair time length also can cause face gas to transfinite, and has very big potential safety hazard for highly gassy mine.
Existing pipeline deslagging device, the gas drainage system of must stopping transport during slagging-off very easily causes gas exceeding limit, makes mine gas administer become unusual difficult.Can not concentrate the cleaning foreign material, slagging-off speed is slow, waste of manpower, material resources.Existing slagging-off pipeline is all installed in pumping plant, and limited location system can not effectively remove the gred.Can not monitor what of foreign material, artificial bad judging whether cleared up.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of gas pipeline deslagging device, comprise a threeway slag-discharging device of installing at gas pipeline, outlet side at the threeway slag-discharging device is provided with filter screen, the slag-drip opening of described threeway slag-discharging device seals with blind plate, the inlet end of described threeway slag-discharging device and outlet side are respectively equipped with valve A and valve B, are provided with the top Overbridge device at the inlet end of valve A and the outlet side of valve B, and described top Overbridge device is provided with valve C.Described gas pipeline upper filter screen installation place is provided with pressure sensor.
During use, when gas pipeline is installed, this practical new gas pipeline deslagging device is installed at any part of gas pipeline as required, after installing with the valve closing on the top gap bridge pipeline of the utility model gas pipeline deslagging device, with two valve opens on the gas pipeline, can open the gas exhaust place system, system is after operation a period of time, during foreign material process gas pipeline deslagging device place, can be stopped by filter screen, automatically stack is before filter screen, when the foreign material stacking volume surpasses pipeline after half, gas flow rate in the pipeline can increase, the pressure that produces also can increase relatively, at this moment can see the variation of pressure by the pressure sensor that is contained in the filter screen place intuitively, and then can distinguish whether the accumulation of gas pipeline foreign material is serious.
During slagging-off, earlier with the valve open on the gap bridge pipeline on this practical new gas pipeline deslagging device top, two valves on the closed gas pipeline then, at this moment methane gas just passes through from the gap bridge pipeline on top, gas pipeline just can carry out slagging-off work when not stopping the gas exhaust place system, blind plate on the slag-drip opening of the threeway slag-discharging device on the gas pipeline is opened, after foreign material are cleaned out, recovered original state and get final product.
The utility model gas pipeline deslagging device; simple in structure; cost is low; slagging-off can not be shut down in convenient monitoring, also can be according to the mine characteristics by cinder, stone and other big foreign material in the obstruction of stagewise screen cloth baffle plate and the precipitation pipeline; purifying gas flow; the security of operation of protection gas drainage under suction equipment has been saved the man power and material, has improved highly gassy mine down-hole safety of construction.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is specified.
A kind of gas pipeline deslagging device, comprise a threeway slag-discharging device 7 of installing at gas pipeline, be provided with filter screen 1 in the outlet side of threeway slag-discharging device 7, the slag-drip opening of described threeway slag-discharging device 7 seals with blind plate 8, the inlet end of described threeway slag-discharging device 7 and outlet side are respectively equipped with valve A and valve B, be provided with top Overbridge device 5 at the inlet end of valve A and the outlet side of valve B, described top Overbridge device 5 is provided with valve C.Described gas pipeline upper filter screen 1 installation place is provided with pressure sensor 9.
[0011]During use, when gas pipeline is installed, this practical new gas pipeline deslagging device is installed at any part of gas pipeline as required, after installing the valve C on the gap bridge pipeline 5 on the utility model gas pipeline deslagging device top is closed, two valve A on the gas pipeline and valve B are opened, can open the gas exhaust place system, system is after operation a period of time, during foreign material process gas pipeline deslagging device 7 places, can be stopped by filter screen 1, automatically stack is before filter screen 1, when the foreign material stacking volume surpasses pipeline after half, gas flow rate in the pipeline can increase, the pressure that produces also can increase relatively, at this moment can see the variation of pressure by the pressure sensor 9 that is contained in filter screen 1 place intuitively, and then can distinguish whether the accumulation of gas pipeline foreign material is serious.
During slagging-off, earlier the valve C on the gap bridge pipeline 5 on this practical new gas pipeline deslagging device top is opened, two valve A on the closed gas pipeline and valve B then, at this moment methane gas just passes through from the gap bridge pipeline 5 on top, gas pipeline just can carry out slagging-off work when not stopping the gas exhaust place system, blind plate 8 on the slag-drip opening of the threeway slag-discharging device 7 on the gas pipeline is opened, after foreign material are cleaned out, recovered original state and get final product.
