Pumping pump discharge is connect with the collection airbag.
The air collecting pipe includes end pipe, and the end pipe is " L " type quadrature tube, and one end passes through screw thread and the gas production
Mouth connection, the other end are directly connect with the gas mixer chamber by screw thread or are connected by extension tube and the gas mixer chamber
It connects.
The gas mixer chamber includes gas mixer chamber front housing and gas mixer chamber rear shell, the gas mixer chamber front housing with
Gas mixer chamber rear shell is uncovered cylindrical body, is constituted cylindrical structure with screw thread interconnection.
A gas production mouth is installed in the gas mixer chamber front housing end face center position, the gas mixer chamber front housing with
The side of gas mixer chamber rear shell is each uniformly to install 8 air collecting pipes, and the gas mixer chamber rear shell end face center position is logical
It crosses 1 threaded hole and the air shooter is installed.
The air shooter is connect by fast interface with the aspiration pump.
The aspiration pump is mining explosion-proof type aspiration pump, and the pumping pump discharge is connected by fast interface and the collection airbag
It connects.
The underground coal mine SF6 of the utility model leaks hunting wind multiple spot synchronic gas acquisition device, to more after opening aspiration pump
Point carries out gas collection simultaneously and uniformly mixes, and gas is stored in collection airbag.It can be realized while multiple spot is carried out same
Gas sampling is walked, can be realized in same section different spatial, carry out multiple spot, synchronous gas collecting and mixed uniformly function
Energy.The cost of labor and time cost for reducing gas production work, improve the accuracy of gas production work.
The utility model realizes same section different spatial, carries out Multipoint synchronous gas collecting and mixed uniformly original
Reason are as follows:
Gas collecting position is determined first, air collecting pipe type needed for being chosen according to environment on the spot and length, and by gas production mouth
It is mounted on air collecting pipe top, air collecting pipe is mounted on gas mixer chamber.The gas flow of each gas production mouth is adjusted after being completed
