Brief description of the drawings
Hereinafter describe specific embodiments more of the present utility model in detail in exemplary and nonrestrictive mode with reference to the accompanying drawings.In accompanying drawing, identical Reference numeral has indicated same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not draw in proportion.In accompanying drawing:
Fig. 1 is the structural representation of the first gas passage of a kind of gas or aerosol mixing or air mix facilities;
Fig. 2 has the gas of the first gas passage in Fig. 1 or the structural representation of aerosol mixing or air mix facilities.
Detailed description of the invention
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with accompanying drawing, specific embodiment is described in detail.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of gas or aerosol to mix or air mix facilities, comprises the first gas passage and the peripheral sleeve that is arranged on the first gas passage, between sleeve and the first gas passage, forms the second substance channel.The first gas is air, and the second material is aerosol.This device is mainly used in aerocolloidal dilution, is applied to suction toxicological experiment.This kind of scheme also can be used for the mixing of two kinds of materials.Such as mixing of gas and gas.
The first gas passage comprises gas inlet 1, gas inlet pipe 2 and the gas-static chamber 4 and the static pressure chamber outlet 5 that are linked in sequence, wherein, static pressure chamber outlet 5 is for being arranged on the Bi Shang gap, chamber in gas-static chamber 4, and gap is and the circular free of discontinuities gap of gas inlet pipe 2 coaxial lines.By the outlet of slot-shaped static pressure chamber is set, the gas that makes to enter into mixing place is more even, more stable, mix or dilution effect is better, mix or dilution after concentration stabilize, be evenly distributed.By being set, slot-shaped outlet also can prevent the first gas backflow.The course of work is: air compressor machine is to carrying endlessly air by the first gas passage, and the second material passes through the second substance channel conveying gas colloidal sol etc. continuously, exports 5 places in static pressure chamber, and both mix, and reach the object of dilution.
