Description
Technical Field
[0001] This application relates to the field of industrial gas mixing and blending technology, and in particular to a mixed industrial gas flow rate control device. Background Technology
[0002] In industrial production processes, in order to accurately control the flow rates of different gases and thus achieve precise allocation of industrial gases to ensure the efficient operation of industrial production processes, it is necessary to use a mixed industrial gas flow rate control device to regulate and mix the various gases.

When controlling the flow rate of different types of gas, the gas flow rate in each gas delivery branch pipe is measured and displayed by the gas flow meter, and the gas flow rate in each inlet branch pipe is kept stable by adjusting the opening of the inlet one-way valve.
[0004] While existing industrial gas flow rate control devices can mix and blend different types of gases by controlling their flow rates, some particulate impurities may be present in the gases before mixing. These impurities can adhere to the inner wall of the conveying pipe during transport, reducing the inner wall size of the pipe and causing fluctuations in gas flow rate. This results in poor mixing quality of different types of industrial gases, hindering efficient industrial production processes. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a mixed industrial gas flow rate control device that can filter and remove particulate impurities from different types of industrial gases through continuous pre-filtration, thereby preventing impurities from adhering to the inner wall of the inlet branch pipe and causing large fluctuations in the industrial gas flow rate.

A filter mechanism is installed in each filter chamber. The filter mechanism includes a filter screen, a linkage plate, a connecting plate, and an electric telescopic rod.
[0008] Optionally, the second electric telescopic rod is installed at the top center of the filter box, and the second linkage plate is connected to the telescopic part of the second electric telescopic rod. Each of the second linkage plates has two symmetrically opened connection channels.

Detailed Implementation
[0024] The present application will be further described in detail below with reference to the accompanying drawings.
[0025] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of existing industrial airflow speed control devices will be introduced first.
[0026] The existing industrial gas flow rate control device mainly consists of a support platform, a touch panel mounted on the support platform, a gas mixing pipe mounted on the workbench, a pressure gauge mounted on the gas mixing pipe, a gas manifold mounted at the gas inlet of the gas mixing pipe, a gas delivery branch pipe mounted on the return gas pipe, a gas flow meter mounted on the gas delivery branch pipe, and an inlet one-way control valve mounted at the gas flow meter inlet. When controlling the flow rate of different types of gas, the gas flow rate in each gas delivery branch pipe is measured and displayed by the gas flow meter, and the gas flow rate in each inlet branch pipe is kept stable by adjusting the opening of the inlet one-way valve.
[0027] Please see Figures 1-5 This application discloses a mixed industrial airflow speed control device, comprising a support platform 6, a mixing pipe 2 mounted on one side of the support platform 6, an inlet check valve 1 mounted at the inlet of the mixing pipe 2, a manifold 11 connected to the inlet of the mixing pipe 2, and inlet branch pipes 5 connected to the inlet of the manifold 11. There are at least two inlet branch pipes 5, each equipped with a gas flow meter 10, and a filter box 9 connected to the inlet of the gas flow meter 10. The filter box 9 has a quick-install structure at the air inlet and a linkage sealing mechanism 13 at the top. The linkage sealing mechanism 13 includes an electric telescopic rod 131, a linkage plate 132, a filter chamber 133, and a connecting channel 134. Each filter box 9 has two filter chambers 133. A filter mechanism 14 is installed in the filter chamber 133. The filter mechanism 14 includes a filter screen plate 141, a linkage plate 142, a connecting plate 143, and an electric telescopic rod 144.
[0028] Specifically, when regulating the flow rate of different types of industrial gases, the conveying pipelines of different types of industrial gases are first connected to the filter box 9 via quick-connect coupling 8. Under the action of the electric telescopic rod 131, the connecting channel 134 on the linkage plate 132 is connected to the filter chamber 133 on the upper side of the filter box 9. This allows the industrial gas to pass through the corresponding filter chamber 133, where the filter screen 141 filters out particulate impurities. The filtered industrial gas then passes through the gas flow meter 10 and the inlet branch pipe 5 into the manifold 11. Different types of industrial gases entering the manifold 11... The gases will eventually mix in the mixing pipe 2, and the mixed industrial gases will eventually be discharged into the corresponding industrial equipment through the exhaust check valve 4 to ensure the efficient operation of the industrial production process. After different types of industrial gases have been filtered for a period of time, the linkage plate 132 can be moved up and down by the action of the electric telescopic rod 131 to ensure that another filter chamber 133 in the filter box 9 is put into use, so that the continuous filtration of different types of industrial gases can be achieved. The filter screen 141 in the filter chamber 133 that has been used can be moved out by the action of the electric telescopic rod 144 to facilitate the normal cleaning of the filter screen 141 after use.
[0029] Please see Figure 1 , Figure 3 and Figure 4 The electric telescopic rod 131 is installed at the top center of the filter box 9, and the linkage plate 132 is connected to the telescopic part of the electric telescopic rod 131. Each linkage plate 132 has two symmetrically opened connection channels 134.
[0030] As one implementation method, the electric telescopic rod 131 is mainly used to realize the up and down movement of the linkage plate 132 relative to the filter box 9. While the linkage plate 142 moves up and down relative to the filter box 9, it will cause the opening of the connecting channel 134 to contact different filter chambers 133, thereby alternately blocking the two filter chambers 133 in the same filter box 9.
[0031] Please see Figures 2-4 The connecting channel 134 is a convex-shaped three-way structure, and the parts on the filter box 9 that mate with both sides of the linkage plate 132 are hollow structures.
[0032] As one implementation method, the mating parts on both sides of the linkage plate 132 on the filter box 9 are hollow structures, which can ensure that the linkage plate 132 can slide up and down conveniently relative to the filter box 9. At the same time, the sliding parts of the linkage plate 132 and the filter box 9 are sliding seal structures.
[0033] Please see Figure 1 , Figure 3 and Figure 5 An electric telescopic rod 144 is installed on the outer wall of the filter box 9. The telescopic part of the electric telescopic rod 144 is connected to a connecting plate 143. One end of the connecting plate 143 facing away from the telescopic part of the electric telescopic rod 144 is connected to a linkage plate 142. A filter screen plate 141 is installed on the side of the linkage plate 142 facing the filter chamber 133.
[0034] In one implementation, the electric telescopic rod 144 drives the connecting plate 143 to move, and the linkage plate 142 can be extended from the filter chamber 133 with the help of the connecting plate 143. After the linkage plate 142 is extended, the corresponding filter screen 141 will be exposed, so as to facilitate the cleaning of the filter screen 141 after use.
[0035] Please see Figure 5 The filter screen 141 is inserted into the linkage plate 142, and the vertical cross-sectional dimensions of the filter screen 141 match the vertical cross-sectional dimensions of the filter chamber 133.
[0036] As one implementation method, matching the vertical cross-sectional dimensions of the filter screen 141 with the vertical cross-sectional dimensions of the filter cavity 133 can ensure reliable installation of the filter screen 141 within the filter cavity 133.
[0037] Please see Figure 1 , Figure 2 and Figure 5 The connecting plate 143 has an inverted L-shaped structure. The fixed part of the electric telescopic rod 144 is bolted to the filter box 9, and the telescopic part of the electric telescopic rod 144 is bolted to the connecting plate 143.
[0038] In one implementation, the connecting plate 143 can realize the synchronous extension and retraction adjustment of the linkage plate 142 with the extension and retraction part of the electric telescopic rod 144.
[0039] Please see Figures 1-2 Each filter box 9 has a screw-on quick-connect fitting 8 installed at its air inlet, and an air inlet check valve 12 is installed between the air outlet of the filter box 9 and the gas flow meter 10.
[0040] As one implementation method, quick-connect coupling 8 can be used to quickly connect different airflow meters to external industrial gas transmission pipelines.
[0041] Please see Figures 1-2 A pressure gauge 3 is also installed on one side of the top of the mixing pipe 2, and an exhaust check valve 4 is installed at the outlet of the mixing pipe 2.
[0042] As one implementation method, pressure gauge 3 is mainly used to measure the pressure of industrial gas in mixing pipe 2, and exhaust check valve 4 can ensure that the mixed industrial gas is discharged unidirectionally to external industrial equipment.
[0043] Please see Figures 1-2 A touch panel 7 is also installed in the middle of one side wall of the support platform 6. The touch panel 7 is electrically connected to the electric telescopic rod 144, the electric telescopic rod 2131, and the gas flow meter 10.
[0044] As one implementation method, the touch panel 7 is mainly used to coordinate the operation of the electric telescopic rod 144, the electric telescopic rod 2 131, and the gas flow meter 10.
[0045] The specific working principle is as follows: When regulating the flow rate of different types of industrial gases, the conveying pipelines of different types of industrial gases are first connected to the filter box 9 through the quick-connect coupling 8. Under the action of the electric telescopic rod 131, the connecting channel 134 on the linkage plate 132 is connected to the filter chamber 133 on the upper side of the filter box 9. This allows the industrial gas to pass through the corresponding filter chamber 133, where the filter screen 141 filters out particulate impurities. The filtered industrial gas then passes through the gas flow meter 10 and the inlet branch pipe 5 into the manifold 11. The different types of industrial gases entering the manifold 11 are finally mixed in the mixing pipe 2. The mixed industrial gas is then discharged to the corresponding industrial equipment through the exhaust check valve 4, ensuring the efficient operation of the industrial production process. After the different types of industrial gases have been filtered for a period of time, the linkage plate 132 is moved up and down by the electric telescopic rod 131 to ensure the flow rate remains constant. When another filter chamber 133 inside filter box 9 is put into use, continuous filtration of different types of industrial gases can be achieved. The filter screen 141 in the filter chamber 133 that has been used can be removed by the action of the electric telescopic rod 144 to facilitate normal cleaning of the filter screen 141 after use. When mixing different types of industrial gases, by installing filter box 9 at the inlet of gas flow meter 10 on each inlet branch pipe 5, and installing linkage sealing mechanism 13 and filtration mechanism 14 on filter box 9, the device can filter particulate impurities in different types of industrial gases in a continuous pre-filtration manner when regulating the flow rate of different types of industrial gases. This ensures that the flow rate of different types of industrial gases will not fluctuate greatly due to particulate impurities adhering to the inlet branch pipe 5 and manifold 11, thereby improving the mixing and blending quality of different types of industrial gases.
[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
