Abstract

The invention provides a laser mixed gas preparation device which comprises a mounting mechanism, a mixing device is mounted at the top of the mounting mechanism, a driving mechanism is mounted in the mixing device, the mixing device comprises an outer pipe and an inner pipe, the inner pipe is fixedly mounted in the outer pipe, a plurality of gas inlets are formed in the peripheral side of the inner pipe, and a plurality of gas outlets are formed in the peripheral side of the inner pipe. A first air storage tank and a second air storage tank are connected to the outer pipe, a flow guiding device is installed in the inner pipe, two air inlet mechanisms are symmetrically installed on the flow guiding device, a plurality of sealing devices are installed between the outer pipe and the inner pipe, one end of a connecting device is connected with the outer pipe, and the other end of the connecting device is connected with a collecting device. And a fixing device is mounted in the connecting device. The mixing device, the driving mechanism and the flow guide device are combined, so that gas in the gas storage tank I and the gas storage tank II is premixed in the mixing device, the mixing quality is improved, and the mixing precision can be ensured.

Description

technical field [0001] The invention belongs to the technical field of mixed gas preparation, and in particular relates to a laser mixed gas preparation device. Background technique [0002] Mixed gas refers to the gas that contains two or more effective components, or the content of non-effective components exceeds the specified limit. The prior art discloses a gas mixing device (CN201610900814.X), which includes an air compressor with an air inlet and an air outlet, and also includes a first gas storage tank and a second gas storage tank for storing the mixed gas. One air storage tank is connected with the air inlet of the air compressor through the first pipeline, the second air storage tank is connected with the air inlet of the air compressor through the second pipeline, and the first air storage tank is connected with the air compressor through the third pipeline. The air outlet of the air compressor is connected, and the second air storage tank is connected with the ...

Problems solved by technology

[0003] At present, in the preparation process of laser mixed gas, various gases are filled in the same steel cylinder, which is usually mixed naturally, and the gas mixing is not uniform enough, which affects the laser performance and is not easy to use. , multiple gases cannot be pre-mixed, thereby reducing the mixing quality. At the same time, in the preparation process of the laser mixed gas, the mixed gas cannot be guaranteed to be mixed in the same proportion, which reduces the mixing accuracy. The existing laser mixed gas preparation device cannot meet the requirements of contemporary usage requirements
