Description
Technical field
The utility model belongs to technical field of coal mine, is related to a kind of coal mine gas drainage current collector.
Background technology
At present, gas pumping single hole detection generally uses two kinds of instruments of ZKC5 or CJZ-70.Two kinds of equipment can be directly
The parameters such as single hole negative pressure, concentration, flow are read, are widely used in high methane, projecting mine gas pumping.CJZ-
70 need to match using special diversion pipe, and diversion pipe unit price is higher, causes gas pumping cost increase, by coal market
Depression influences, and mine benefit is poor, and input is more nervous, there are certain difficulty in practical application, therefore does not push application open comprehensively;
Mating diversion pipe is not required in ZKC-5, therefore application range is wider.But coal mine gas extraction pipeline connection at present and extraction single hole
Collecting pipe is mostly processing and fabricating inside mine, by processing and fabricating, proficiency is limited, and is added there is no unified standard or equipment
Work precision is inconsistent, and processing efficiency is low, and standardization level is low, and mostly heavy, and maintenance capacity is big and inconvenient, causes single hole in turn
Accuracy of detection and accuracy are inconsistent.
Current collector is an important component in gas drainage system, and the current collector of ZKC-5 equipment utilizations is similary
Ununified standard and specification, current collector are mostly integral type manufacture, and there is various deficiencies:In removing and installing not for underground
Conveniently, the problems such as structure design of collection slag device and the tailrace that removes the gred is unreasonable.
Utility model content
In view of the deficienciess of the prior art, technical problem to be solved in the utility model is existing current collector modularization
Degree is not high, and catchment effect is bad, and waste residue is not easy to separate with gas.
In order to solve the above technical problems, the utility model is a kind of coal mine gas drainage current collector, including gas collecting tube, institute
The one end for stating gas collecting tube is connected threeway connection by elbow with extraction branch pipe, and the other end and the slagging-off tailrace of the gas collecting tube are consolidated
Fixed connection, the gas collecting tube are equipped with multiple single hole collecting pipes, and the upper end of the single hole collecting pipe is connected with gas collecting tube, the list
The lower end of hole collecting pipe is connected with collection slag device, and the single hole collecting pipe is equipped with multiple diversion pipes, the diversion pipe and the external world
Tunnel connects, and the diversion pipe is equipped with ball valve, and the diversion pipe is obliquely installed and is 30 degree -60 with the angle of vertical direction
Degree.
Further, the interface of left and right two of the extraction branch pipe connection threeway connects respectively with extraction branch pipe.
Further, the opening direction of the diversion pipe tilts upward setting, and the single hole collecting pipe is vertically arranged.
Further, the elbow is equipped with butterfly valve.
Further, the both ends of the collection slag device are equipped with slagging-off tailrace, and the slagging-off tailrace is equipped with ball valve.
Further, multiple single hole collecting pipes are arranged in parallel, and multiple diversion pipes are arranged in parallel.
Further, multiple catch diagonally downward are equipped in the single hole collecting pipe, the catch is located at single hole collecting pipe
With diversion pipe junction.
The beneficial effects of the utility model:
1) collection slag device is located at the lowest part of whole device, and this setup is conducive to diversion pipe and single hole collecting pipe
The waste residue and waste water of middle gas are gathered in the lowest part of device by gravity, are conducive to concentrate discharge;
2) in a manner that water conservancy diversion tube opening tilts upward setting, gas enters in diversion pipe first downlink subsequently into single hole
In collecting pipe, this special set-up mode can cause waste residue to obtain downward speed, be converged convenient for waste residue and gas in single hole
The inlet of flow tube separates and accumulates in collection slag device.
3) using catch diagonally downward diversion pipe can further be coordinated to tilt and the setting of opening upwards, catch can be with
So that it loses kinetic energy into the waste residue in diversion pipe and sinks and gather in slag device is collected.
