Abstract
The utility model provides a kind of for discharging the tailrace of coal extraction gas pipeline, including main body water tank, main body tank top is provided with water inlet, the water inlet is provided with control piece, main body tank top is additionally provided with ventilating bent-tube and has butterfly valve by flanged joint, and main body water tank front is provided with water outlet, and the water outlet is provided with control piece, main body water tank left side is provided with ventilation straight tube, and the ventilation straight tube has butterfly valve by flanged joint.It realizes tailrace quick separating is installed with extraction pipeline and connect and pass through two groups of butterfly valve control snorkels, realizing that partition discharges water does not influence the normal extraction of other extraction pipelines.
Description
Technical field
The utility model relates to mining equipment technical fields, and in particular to a kind of for discharging coal extraction gas pipeline
Tailrace.
Background technique
During mash gas extraction, it may appear that the case where water blocking.This is because drilling had big portion at formation initial stage originally
Water is divided to generate, the moisture of coal body itself, causes to gather a large amount of ponding inside gas drainage pipeline, extraction pipeline is one in addition
The environment of negative pressure line, i.e. air pressure in extraction pipeline are less than atmospheric pressure, and extraction pipeline there may be liquid water, work as liquid water
Cannot in time discharge line and cause the effective cross-section of local pipeline to be obviously reduced, can serious shadow or even when blocking extraction pipeline
Ring extracting result.
The horizontal bore water yield of two crossheading of mine working face in the pit construction is big, the installation of the tailrace of the prior art is complicated, when
When needing to increase waterdrainage amount, if drainage tube road is equipped with tailrace, the tailrace now connected influences installed discharge water
The normal extraction of device.
Summary of the invention
The utility model provides a kind of tailrace, solves prior art chats decentralization hydrophone and discharges water scarce capacity, installation
The problems such as complicated, inconvenient.
In order to achieve the above object, the utility model provides a kind of for discharging the tailrace of coal extraction gas pipeline,
Including main body water tank, main body tank top is provided with water inlet, and the water inlet is provided with control piece, and main body tank top is also set
It is equipped with ventilating bent-tube and has butterfly valve by flanged joint, main body water tank front is provided with water outlet, the water outlet setting
There is control piece, main body water tank left side is provided with ventilation straight tube, and the ventilation straight tube has butterfly valve by flanged joint.
The main body tank top water inlet diameter is less than main body water tank front water outlet diameter.
The main body water tank inlet, water outlet control piece be ball valve.
The utility model is compared with the existing technology: 1, tailrace and extraction pipeline, which are installed, can be achieved quick separating and connection.
2, snorkel is controlled by two groups of butterfly valves, realizing that partition discharges water does not influence the normal extraction of other extraction pipelines.3, it is widely used,
Both it was suitble to drill site to use, general gas drainage pipeline is also suitble to use.4, convenient disassembly, composition material is simple, be easily installed and
Disassembly.
Detailed description of the invention

A kind of embodiment schematic diagram of Fig. 2 the utility model tailrace；
Appended drawing reference: main body water tank -1, water inlet -2, water inlet control piece -3, ventilating bent-tube -4, flange -5, butterfly valve -6,
Water outlet -7, water outlet control piece -8, straight tube -9 of ventilating, flange -10, butterfly valve -11.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of for discharging the tailrace of coal extraction gas pipeline, including main body water tank (1), the master
It is provided with water inlet (2) at the top of body water tank (1), the water inlet is provided with control piece (3), and main body tank top is additionally provided with logical
Gas bend pipe (4) is simultaneously connected with butterfly valve (6) by flange (5), and main body water tank front is provided with water outlet (7), the water outlet
Mouth (7) is provided with control piece (8), and main body water tank left side is provided with ventilation straight tube (9), and the ventilation straight tube passes through flange
(10) butterfly valve (11) are connected with.It is straight that main body tank top water inlet (2) diameter is less than main body water tank front water outlet (7)
Diameter.The main body water tank inlet, water outlet control piece be ball valve.
In one embodiment, as shown in Fig. 2, processing main body water tank first, not according to 800*500*600 mm(model
Limit adaptation) dimensioned, 10 straight-through, 146 elbows and 146 steel pipe of 600mm and 125 ring flanges, water are welded in top
159 pipe collars are welded immediately ahead of case, left side welds 146 steel pipe 50mm and 125 ring flanges against the top, still further welds 146 steel
10 straight-through valves are finally installed to extraction pipeline, vacuum table is mounted on orifice flow by two groups of pipe 50mm and 125 ring flanges
On meter.
When operation, due to being that partition discharges water, two Handle of butterfly valve is rotated, two butterfly valves are simultaneously closed off, open simultaneously top
25 ball valves of 10 ball valves and front, the ponding being collected in extraction pipeline just flows out, if water velocity is slow, can fit
When the butterfly valve opening and closing for adjusting main body water tank left side ventilation straight tube, main body tank top ventilating bent-tube, easy for installation, structure
Simply, tailrace and extraction pipeline installation quick separating are realized and connect and passes through two groups of butterfly valves and controls snorkels, realization every
Disconnected discharge water does not influence the normal extraction of other extraction pipelines.
