FIG. 2 is a cross-sectional view of a pneumatic vacuum generator in accordance with an embodiment of the present invention;
in the figure: a measured gas container 1; an oxygen analyzer 2; an inlet 2-1; an outlet 2-2; a vacuum filter 3; a pneumatic vacuum generator 4; a supply port 4-1; 4-2 of a nozzle; 4-3 of a diffusion chamber; 4-4 of a diffuser; 4-5 of a vacuum suction inlet; 4-6 of an exhaust port; an exhaust pipe 5; and an instrument gas source pipeline 6.
Detailed Description
The present invention will be further described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, the present embodiment is an oxygen analysis and measurement device for a dust environment, and the device is composed of a silicon powder processing system pipeline 1, an oxygen analyzer 2, a vacuum filter 3, a pneumatic vacuum generator 4, an exhaust pipe 5, and an instrument gas source pipeline 6. The silicon powder processing system pipeline 1 is communicated with an inlet 2-1 of an oxygen analyzer 2 through a pipeline, an outlet 2-2 of the oxygen analyzer 2 is communicated with an air inlet end of a vacuum filter 3 through a pipeline, an air outlet end of the vacuum filter 3 is communicated with a pneumatic vacuum generator 4, the pneumatic vacuum generator 4 (shown in figure 2) has the overall dimension of 160mm in length, 40mm in width and 30mm in height, the pneumatic vacuum generator 4 is composed of a supply port 4-1 and a nozzle 4-2, the device comprises a diffusion chamber 4-3, a diffuser 4-4, a vacuum suction inlet 4-5 and an exhaust port 4-6, wherein the air outlet end of a vacuum filter 3 is communicated with the vacuum suction inlet 4-5 of a pneumatic vacuum generator 4, a supply port 4-1 of the pneumatic vacuum generator 4 is communicated with an instrument gas source pipeline 6, and the exhaust port 4-6 is provided with an exhaust pipe 5.
The working process of the embodiment is as follows: compressed air from an instrument air source pipeline 6 passes through a supply port 4-1 of a pneumatic vacuum generator 4 and then flows through a one-way nozzle 4-2 to be discharged, the compressed air is expanded and the flow rate is increased in a diffusion chamber 4-3 and then passes through a diffuser 4-4, a vacuum suction port 4-5 tangent to the compressed air flow is arranged at an air suction point between an outer hole and the diffuser 4, and detected air flow sucked into the vacuum suction port 4-5 is mixed with the compressed air flow and then discharged from an exhaust port 4-6 at the opposite end. The compressed air of the instrument gas source pipeline 6 generates negative pressure when flowing through the pneumatic vacuum generator 4, the measured gas in the silicon powder processing system pipeline 1 is sucked into the oxygen analyzer 2 through the inlet 2-1 of the oxygen analyzer 2, the oxygen content value is measured, the measured gas enters the vacuum suction inlet 4-5 of the vacuum generator 4 through the outlet 2-2 of the oxygen analyzer 2 and the vacuum filter 3 and then is mixed with the compressed air, and finally the gas is discharged through the exhaust pipe 5.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all structural equivalents made by using the contents of the specification and drawings are included in the scope of the present invention.
