Abstract
The invention relates to a mixer used for ventilation air methane and drawing-out methane and having an automatic concentration control function, belonging to the field of gas supplying technology for oxidation apparatuses of coal mine ventilation air methane. The mixer provided by the invention has a cylindrical shell; two ends of the shell are a ventilation air methane inlet end and a mixed gas outlet end, respectively; the excircle surface of the shell is provided with a plurality of drawing-out methane inlet pipes; the ventilation air methane inlet end of the shell is provided with a transition pipe with increasingly decreasing diameters; the transition pipe is connected with the shell via casting or welding; the tail end surface of the transition pipe is located at one side, close to the ventilation air methane inlet end, of the axis of each of the drawing-out methane inlet pipes; the shell is also internally provided with a valve core capable of moving along the axis of the shell; a gas inlet gap is formed between one end surface of the valve core and the end surface, close to the ventilation air methane inlet end, of the transition pipe, and the other end of the valve core is fixedly connected with a driving mechanism driving the valve core to move; and the mixer is further provided with a gas flow valve body. The mixer provided by the invention realizes uniform mixing of large-flow ventilation air methane and drawing-out methane and has a wide application scope.
