Description

Technical Field

[0001] The utility model belongs to the technical field of gases, and in particular relates to a rapid mixing device for a mixed gas cylinder. Background Art

[0002] In the process of semiconductor, photovoltaic, LED and other precision electronics industries, various mixed gases with specific proportions are used. Whether the ratio of the mixed gas meets the standard during use is related to the quality of the final product. Usually, the mixed gas production process is to fill the gases of different components into high-pressure gas cylinders in a certain order. Due to the difference in gas density, the gas components are usually distributed in layers. After the gas cylinder is placed for a long time, due to the influence of gravity, the gas with high density will be distributed at the bottom of the bottle, and the gas with light density will be distributed at the top of the bottle. In order not to affect the subsequent use, the gas in the cylinder needs to be mixed.

[0003] Chinese patent CN 216987345 U controls the parallel and co-rotating wheels by a rolling method, controls the gas cylinder located between the two wheels to rotate, and further mixes the gas inside the gas cylinder during its rotation.

[0004] Patent CN 219111452 U uses a rolling method to simultaneously rotate and drive the gas cylinder up and down, increasing the movement dimension of the gas cylinder, making the mixed gas in the bottle experience a larger oscillation amplitude, thereby enhancing the mixing effect.

[0005] However, the rolling method has many disadvantages. First, the mixing efficiency is low. One mixer can usually only mix one gas cylinder. Second, it is also a test of the bearing strength and service life of the roller. Finally, for gases with large relative density differences, the rolling method usually takes a long time to mix. Therefore, it is necessary to provide an efficient and long-life gas mixing device. Summary of the invention

[0006] In view of the above technical problems, the utility model provides a mixed gas cylinder rapid mixing device, which generates convection movement by forming a temperature difference in the cylinder, so that gas components with different densities are quickly and evenly mixed, thereby improving work efficiency and shortening the production cycle.

[0007] In order to achieve the above purpose, the utility model provides a mixed gas cylinder rapid mixing device, a chiller is provided at one end of the cylinder, a hot water unit is provided at the other end, and a first retractable support frame and a second retractable support frame are provided at the bottom of the cylinder.

[0008] Preferably, one end of the chiller is connected to a first hose via a chiller outlet flow regulating valve, the first hose is connected to a first coil, and the first coil is connected to the chiller via the first hose and a chiller return flow regulating valve.

[0009] Further preferably, a chiller outlet water thermometer is provided between the chiller outlet water flow regulating valve and the first hose; and a chiller return water thermometer is provided between the first hose and the chiller return water flow regulating valve.

[0010] Preferably, one end of the hot water unit is connected to the second hose via the hot water unit outlet flow regulating valve, the second hose is connected to the second coil, and the second coil is connected to the hot water unit via the second hose and the hot water unit return flow regulating valve.

[0011] Preferably, a hot water unit outlet water thermometer is provided between the hot water unit outlet water flow regulating valve and the second hose; and a hot water unit return water thermometer is provided between the second hose and the hot water unit return water flow regulating valve.

[0013] More preferably, the first coil is in close contact with one side of the gas cylinder; and the other side of the gas cylinder is in close contact with the second coil.

[0014] The beneficial effects of the present invention are:

[0015] 1. Use the chiller and hot water unit to provide heat source and cold source for the gas cylinder respectively, so as to create a temperature difference between the upper and lower parts of the gas cylinder, drive the gas to convect under the action of the temperature difference, so that the various gases with different densities in the gas cylinder move in the bottle and mix quickly and fully, shortening the production cycle of the mixed gas and improving work efficiency.

[0016] 2. The first retractable support frame and the second retractable support frame are used to fix and support the gas cylinder, so as to facilitate the transportation of the gas cylinder.

[0017] 3. There are multiple thermometers on the gas cylinder and the hose, which can monitor the temperature changes of various parts of the gas cylinder, the chiller and the hot water unit in real time, ensuring that there is a certain temperature difference inside the gas cylinder and convection movement occurs smoothly.

[0018] 4. The coil is adapted to the specifications of the gas cylinder and coiled on one side of the gas cylinder to ensure that the coil fits tightly against the wall of the gas cylinder to enhance the heat transfer effect.
