Description

Technical Field

[0001] This utility model belongs to the field of gas mixing technology, specifically a gas mixing and supply device. Background Technology

[0002] With the rapid development of industries such as industry, medicine, food processing, and laboratories, the application of gas mixing technology has become increasingly widespread. Gas mixing involves mixing two or more gases with different properties in a specific ratio to meet the needs of different scenarios. For example, in the medical field, the mixture of oxygen and nitrogen can be used for anesthesia or respiratory support; in food processing, mixed gases are widely used in modified atmosphere packaging to extend the shelf life of food; and in the chemical and pharmaceutical industries, gas mixtures in specific ratios can be used for reaction control or environmental simulation.

[0003] Currently, the common method for gas mixing is to extract multiple gases from their respective storage tanks and then merge them into a mixing tank through a single pipeline. This method can effectively concentrate different gases into the mixing tank, reduce the complexity of pipeline connections, and lower equipment installation and maintenance costs. However, during the process of gas intake through a single pipeline, the inconsistent flow rates of multiple gases can easily lead to uneven mixing in local areas, affecting the uniformity of gas mixing and system stability. This can result in uneven mixing of subsequent output gases, affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a gas mixing and supply device to solve at least one aspect of the problems and defects mentioned in the background art.

[0005] A gas mixing and supply device is provided, including a mounting base. Several mounting slots are provided on the top of the mounting base, and each of the mounting slots contains a gas mixing tank. A limiting mechanism is provided on the upper part of the mounting base. Each gas mixing tank is provided with an outlet pipe, and each outlet pipe is connected to an annular gas injection pipe. The annular gas injection pipe is connected to a mixing tank through several gas guide pipes. A gas mixing mechanism is provided inside the mixing tank, and an input pipe is provided at the bottom of the mixing tank. A diffusion mechanism is provided at the end of the input pipe.

[0006] Furthermore, the mixing tank is provided with several exhaust ports, each of which is connected to a gas guide pipe. The gas guide pipes are connected to each exhaust port to uniformly discharge the gas. The point exhaust design allows the gas in the mixing tank to be discharged evenly, avoiding local concentration deviations caused by single-point exhaust.

[0007] Furthermore, each of the air outlet pipes is equipped with a first solenoid valve, which is used to control the opening and closing of each air outlet pipe.

[0008] Furthermore, the limiting mechanism includes a limiting frame, which is fixedly connected to the mounting base. Electric push rods are symmetrically arranged on both sides of the upper part of the limiting frame. A protective ring is fixedly connected to the telescopic end of each electric push rod. The electric push rod can adjust the position and clamping force of the protective ring to accommodate gas distribution tanks of different diameters or sizes, facilitating quick replacement or adjustment of the gas distribution tanks by operators. While fixing the tank, the protective ring provides a certain degree of protection to its surface, preventing damage to the gas distribution tank due to external impact or vibration.

[0009] Furthermore, each of the mounting slots is equipped with a silicone pad, which has good elasticity and shock absorption properties, and can absorb external vibrations or impacts to prevent the bottom of the gas distribution tank from being impacted by external forces.

[0010] Furthermore, the gas mixing mechanism includes a drive motor, which is positioned above the mixing tank. The output end of the drive motor is fixedly connected to a mounting shaft with a detachable agitator blade. The drive motor provides stable rotational power through its output end, driving the mounting shaft to rotate, which in turn transmits the rotational power to the agitator blades. As the blades rotate, they create vortices and turbulence within the mixing tank, breaking up gas stratification. This increases the contact frequency and mixing path of gas molecules, allowing for rapid and uniform distribution of different gas components. It significantly improves mixing efficiency, making it suitable for scenarios requiring high mixing uniformity. It also reduces mixing time, improving the overall operating efficiency of the equipment.

[0011] Furthermore, the diffusion mechanism includes a diffusion chamber located at the end of the input pipe. Inside the diffusion chamber are several diffusion plates arranged along its height. A delivery pipe connects to the bottom of the diffusion chamber. A second solenoid valve is installed on the input pipe. The diffusion chamber diffuses the incoming gas internally, reducing the airflow velocity. The diffusion plates divide the gas entering the diffusion chamber into multiple streams, and through diversion and turbulence, make the gas flow more uniform. The delivery pipe guides the diffused gas to the target location, ensuring efficient delivery of the uniformly distributed gas. The second solenoid valve opens or closes the input pipe via an electrical signal, achieving precise regulation of the gas flow rate and ensuring the uniformity and stability of the output gas. This improves the consistency of the mixed gas during downstream use.

[0012] Furthermore, each of the diffuser plates is provided with a gas guide hole, which is used to guide the gas flow and increase the flow path, reduce the concentration of gas flow, and avoid gas accumulation or excessive flow velocity in local areas.

[0013] Furthermore, the diffusion chamber is an inverted cone-shaped diffusion chamber. When the mixed gas enters the diffusion chamber, the gas flow rate slows down due to the larger upper space. As the gas flows down to the gradually narrowing lower region, the gas flow rate gradually recovers and is controlled. The deceleration effect at the top helps the gas to diffuse and mix, while the narrowing lower region re-rectifies the airflow to ensure a uniform output flow rate.

[0014] Furthermore, a honeycomb rectifier is installed at the bottom of the conveying pipeline. The honeycomb rectifier is composed of multiple small holes or honeycomb channels, which can effectively stabilize and reduce turbulence, so that the gas output from the conveying pipeline can enter the next process more smoothly.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This gas mixing and supply device is used to mix multiple gas distribution pipes according to a set ratio, ensuring the uniformity of the mixed gas. The mixture is then discharged through an output pipe. A ring-shaped injection pipe and multi-point air intake design uniformly introduce different gases into a mixing tank. A gas mixing mechanism inside the mixing tank further enhances the mixing uniformity. A diffusion mechanism at the end of the outlet pipe ensures the uniformity and stability of the output gas. Through the coordinated operation of the ring-shaped injection, multi-point air intake, gas mixing mechanism, and diffusion mechanism, the uniformity and stability of the mixed gas are significantly improved, enhancing gas mixing uniformity and system stability, preventing uneven mixing of subsequent output gases, and improving product quality.

Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.

[0026] Please see Figure 1-4 As shown in the embodiment of this utility model, a gas mixing and supply device includes a mounting base 1. The mounting base 1 has several mounting slots 11 on its upper surface, and each of the mounting slots 11 contains a gas mixing tank 2. A limiting mechanism 3 is provided on the upper part of the mounting base 1. The limiting mechanism 3 prevents the gas mixing tank 2 from shaking by mechanically limiting it (such as by a clamping device or a fixed bracket). This improves the stability of the gas mixing tank 2, especially when valves are opened or closed or gas flows. It also reduces the impact of external vibrations on equipment operation.

[0027] Each gas distribution tank 2 is equipped with an outlet pipe 4, which is connected to an annular gas injection pipe 5. The annular gas injection pipe 5 is connected to a mixing tank 7 via several gas guide pipes 6. The annular gas injection pipe 5 distributes the gas evenly into the mixing tank 7 from multiple directions, achieving multi-point gas intake and avoiding local gas accumulation or excessively fast flow rate caused by single-point gas intake. This improves the uniformity of the gas entering the mixing tank 7, providing a basis for subsequent mixing. A gas mixing mechanism 8 is installed inside the mixing tank 7. An input pipe 9 is installed at the bottom of the mixing tank 7, and a diffusion mechanism 10 is installed at the end of the input pipe 9. The diffusion mechanism 10 at the end of the outlet pipe 4 further disperses and homogenizes the mixed gas through a porous structure or diversion design. This eliminates potential gas velocity differences at the outlet of the mixing tank 7, ensuring uniform flow rate and concentration of the output gas, and providing a stable gas source for downstream equipment or processes.

[0028] This gas mixing and supply device is used to mix gases from multiple gas distribution tanks 2 according to a set ratio, ensuring the uniformity of the mixed gas. Finally, the gas is discharged through the delivery pipe 103. The integration and mixing of multiple gas sources, through the annular gas injection pipe 5 and multi-point gas inlet design, uniformly introduces different gases into the mixing tank 7. The mixing tank 7 is equipped with a gas mixing mechanism 8 (such as a stirring device or a flow guiding structure) to further improve the mixing uniformity. Through the diffusion mechanism 10 at the end of the gas outlet pipe 4, the uniformity and stability of the output gas are ensured. Through the coordinated work of the annular gas injection, multi-point gas inlet, gas mixing mechanism 8 and diffusion mechanism 10, the uniformity and stability of the mixed gas can be significantly improved, avoiding uneven mixing in local areas caused by inconsistent flow rates of multiple gases. This can improve the uniformity of gas mixing and system stability, avoid uneven mixing of subsequent output gases, and improve product quality.

[0029] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the mixing tank 7 is provided with several exhaust ports 71, and each exhaust port 71 is connected to a gas guide pipe 6. The gas guide pipe 6 is connected to each exhaust port 71 to uniformly discharge the gas. The point exhaust design enables the gas in the mixing tank 7 to be discharged evenly, avoiding local concentration deviation caused by single-point exhaust.

[0030] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, each of the air outlet pipes 4 is equipped with a first solenoid valve 200, which is used to control the opening and closing of each air outlet pipe 4.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the limiting mechanism 3 includes a limiting frame 31, which is fixedly connected to the mounting base 1. Electric push rods 32 are symmetrically arranged on both sides of the upper part of the limiting frame 31. Protective rings 33 are fixedly connected to the telescopic ends of the electric push rods 32. The electric push rods 32 can adjust the position and clamping force of the protective rings 33 to accommodate gas distribution tanks 2 of different diameters or sizes. This allows operators to quickly replace or adjust the gas distribution tanks 2. While fixing the tank 2, the protective rings 33 also provide a certain degree of protection to its surface, preventing damage to the gas distribution tank 2 due to external impacts or vibrations. A rubber layer is provided on the upper part of each protective ring 33 to protect the surface of the gas distribution tank 2.

[0032] In one embodiment, see Figure 2 and Figure 4 As shown, each mounting slot 11 is equipped with a silicone pad. The silicone pad has good elasticity and shock absorption properties, which can absorb external vibration or impact force and prevent the bottom of the gas distribution tank from being impacted by the outside.

[0033] In one embodiment, see Figure 1 and Figure 4 As shown, the gas mixing mechanism 8 includes a drive motor 81, which is mounted above the mixing tank 7. The output end of the drive motor 81 is fixedly connected to a plate mounting shaft 82, and several stirring blades 83 are detachably connected to the plate mounting shaft 82.

[0034] The drive motor 81 provides stable rotational power through its output end, driving the mounting shaft 82 to rotate. This rotational power is then transmitted to the stirring blades 83. As the stirring blades 83 rotate, they create vortices and turbulence within the mixing tank 7, breaking up gas stratification. This increases the contact frequency and mixing path of gas molecules, allowing for rapid and uniform distribution of different gas components. It significantly improves mixing efficiency, making it suitable for applications requiring high mixing uniformity. Furthermore, it reduces mixing time and enhances the overall operating efficiency of the equipment.

[0035] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the diffusion mechanism 10 includes a diffusion chamber 101, which is located at the end of the input pipe 9. The diffusion chamber 101 contains several diffusion plates 102 arranged along its height. A delivery pipe 103 connects to the bottom of the diffusion chamber 101. A second solenoid valve 201 is installed on the input pipe 9. The diffusion chamber 101 diffuses the incoming gas internally, reducing the airflow velocity. The diffusion plates 102 divide the gas entering the diffusion chamber 101 into multiple streams, and through diversion and turbulence, make the gas flow more uniform. The delivery pipe 103 guides the diffused gas to the target location, ensuring efficient delivery of the uniformly distributed gas. The second solenoid valve 201 is controlled by an electrical signal to open or close the input pipe 9, achieving precise regulation of the gas flow rate and ensuring the uniformity and stability of the output gas. This improves the consistency of the mixed gas during downstream use.

[0036] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, each of the diffuser plates 102 is provided with a gas guide hole 1021. The gas guide hole 1021 is used to guide the gas flow and increase the flow path. This reduces the concentration of gas flow and avoids gas accumulation or excessively high flow velocity in local areas.

[0037] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the diffusion chamber 101 is an inverted cone-shaped diffusion chamber. When the mixed gas enters the diffusion chamber 101, the gas flow rate slows down due to the larger upper space. As the gas flows down to the gradually narrowing lower region, the gas flow rate gradually recovers and is controlled. The deceleration effect at the top helps gas diffusion and mixing. The lower narrowing region re-rectifies the airflow to ensure a uniform output flow rate.

[0038] In one embodiment, see Figure 1 , Figure 2 and Figure 3 A honeycomb rectifier 12 is provided at the bottom of the conveying pipe 103. The honeycomb rectifier 12 is composed of multiple small holes or honeycomb channels, which can effectively stabilize and reduce turbulence, so that the gas output from the conveying pipe 103 can enter the next process more smoothly.

[0039] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
