Description

Technical Field

[0001] The invention relates to the technical field of gas mixing, and in particular to a gas mixing device. Background Art

[0002] Gas mixing equipment is a device used to evenly mix two or more different gases in a specific proportion. Its core function is to evenly mix two or more different gases in a specific proportion. It has indispensable applications in the semiconductor, environmental protection, photovoltaic, chemical, medical and other industries to ensure that the mixed gas can meet specific process requirements, such as the gas mixing device disclosed in the Chinese patent publication number CN111992065B.

[0003] Existing gas mixing equipment usually directly mixes the gases discharged from different gas cylinders, and the gases are usually stored in the gas cylinders in a compressed state. According to the ideal gas state equation and the law of conservation of energy, the gas directly discharged has a reduced volume and increased pressure when compressed, and the distance between molecules is shortened, which increases the molecular potential energy and correspondingly reduces the molecular kinetic energy. Temperature is a reflection of the intensity of molecular thermal motion, and the molecular kinetic energy is reduced, which leads to a lower temperature of the directly discharged gas.

[0004] However, lower temperatures will slow down the thermal motion of gas molecules, reduce the frequency of collisions and energy exchange between molecules, and make it difficult for gas molecules to diffuse and interpenetrate quickly during the mixing process. This will make it impossible to fully break the original aggregation state and concentration gradient, leading to stratification. This will affect the flow characteristics of the gas in the mixing equipment, making the gas flow path unstable and unable to achieve a uniform mixing effect. Summary of the invention

[0023] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0024] 1. The cooling gas discharged from the gas cylinder is heated up through the outer box, the exhaust fan, the cold and heat exchange component and the conduction component in the gas pressure relief mechanism, so that the cooling gas is restored to the ambient temperature. The exhaust fan draws the outside air into the outer box through the vent hole of the outer box and discharges it, so as to complete the circulation of the outside air and the air in the outer box. The cold and heat exchange component is used to store the exhausted cooling gas. At the same time, since the cooling gas fills the cold and heat exchange component, when the outside air and the air in the outer box circulate, the cold flow transmitted by the cooling gas in the cold and heat exchange component will be taken away together, so as to realize the heating operation of the cooling gas. At the same time, since the outer box has a gas storage box and a telescopic box, the outer box can be deformed accordingly according to the amount of cooling gas entering, and the conduction component is used to improve the effect of the cold and heat exchange of the cooling gas. By heating the cooling gas discharged from the gas cylinder to the ambient temperature, the problems such as slow thermal motion of gas molecules and uneven mixing caused by the direct participation of low-temperature gas in the mixing are avoided, and the mixed gas is ensured to be fully mixed under appropriate temperature conditions.

[0025] 2. Through the gas input and output components, mixing barrel, mixing and converging components, stirring components and mixing components in the gas mixing mechanism, multi-path transmission, convergence, stirring and mixing of different gases that have completed heating can be realized, wherein the module diversion mechanism transfers the gas that has completed heating to the gas input and output components, and the gas input and output components can transmit the gas to the mixing barrel in multiple paths, so that the gas fully fills the mixing barrel, and the mixing and converging components are used to converge the gas dispersed in the mixing barrel, and the converged gas is mixed and dispersed again by using the stirring components and the mixing components, so as to realize the cycle process of continuous convergence and dispersion of the gas in the mixing barrel, and realize full mixing of the gas, and utilize the multi-path transmission function of the gas input and output components to ensure that the gas can fully fill the mixing barrel, increase the contact opportunities between gases, and effectively converge the dispersed gas, and then combine the stirring components and the mixing components to make the gas continuously converge and disperse in a cycle, which effectively promotes the full mixing of the gas.

[0026] 3. Through the vibration rod and resonance component in the gas mixing mechanism, the vibration wave can be used to further promote the gas mixing. Among them, by using the non-Newtonian liquid contained in the vibration zone, combined with the vibration rod and the resonance component, the gas in the mixing barrel can be uniformly guided to avoid excessive concentration of vibration waves, so that the gas molecules in the mixing barrel can be subjected to relatively balanced vibration excitation, which enhances the movement activity of the gas molecules and the frequency of mutual collision, thereby accelerating the gas mixing process.

In addition, the module diversion mechanism 3 is used to control the transmission of the gas processed by the gas pressure relief mechanism 2 to enter the gas mixing mechanism 4. The gas mixing mechanism 4 uses the gas input and output component 42 to realize multi-path transmission of the gas before mixing to the mixing barrel 45.

[0053] The outer box 21 is fixed in the slide rail 11 by fixing the fixing piece 22 in the corresponding mounting hole 12, and the air in the outer box 21 is sucked through the exhaust fan 23, so that the outside air enters the outer box 21 from the vent 212 due to the negative pressure, thereby realizing the continuous circulation of the outside air in the outer box 21, so as to provide conditions for subsequently taking away the surface temperature of the cold and heat exchange component 24.

[0054] Reference Figures 4 to 5 The heat exchange component 24 includes an air storage box 241 placed inside the outer box 21, and a telescopic box 242 is fixedly connected in the middle of the air storage box 241.

[0068] The main valve 31 in the module diversion mechanism 3 can cooperate with the gas pressure relief mechanism 2 to limit the minimum gas type for gas transmission and provide an interface for the subsequent addition of auxiliary valves 33. The number of auxiliary valves 33 added and the number of gas pressure relief mechanisms 2 are determined by the type of gas.

[0069] The operating principle of this embodiment is as follows:

[0070] Step 1: First, the staff places the outer box 21 of the gas pressure relief mechanism 2 on the base 1 through the slide rail 11 (the number of gas pressure relief mechanisms 2 placed on the base 1 is determined by the type of gas, that is, each gas corresponds to a gas pressure relief mechanism 2), so that the fixings 22 on both sides of the outer box 21 are aligned with the mounting holes 12 in the base 1 (the spacing between two adjacent gas pressure relief mechanisms 2 can be customized by the staff according to actual conditions), and then use a tool to pass the screws in the fixings 22 through the connecting blocks of the fixings 22 and screw them into the corresponding mounting holes 12 and tighten them, so that the outer box 21 is tightly connected to the base 1 to ensure that the gas pressure relief mechanism 2 will not be displaced due to vibration or other external factors during the operation of the equipment (the equipment in this solution refers to the gas mixing equipment);

[0071] Then, the air inlet pipe 211 of each gas pressure relief mechanism 2 is connected to the corresponding gas cylinder, so that the gas enters the gas storage box 241 of the cold and heat exchange component 24 through the air inlet pipe 211 and the contraction tube 243, and the telescopic box 242 in the middle of the gas storage box 241 is deformed due to the gas pressure (the telescopic box 242 is in a compressed state under the action of the elastic component 25 when no gas is input), and the roller 245 is used to provide support for one side of the gas storage box 241 that moves due to the deformation of the telescopic box 242, and the positioning block 246 is used to support the side of the gas storage box 241 that moves due to the deformation of the telescopic box 242. The other side of the gas storage box 241 is now fixed to the outer box 21, so that when the telescopic box 242 is deformed, the gas storage box 241 on one side moves synchronously with the telescopic box 242 (referring to the side containing the roller 245), and the gas storage box 241 on the other side fixes the gas storage box 241 and the telescopic box 242 at the initial position of the outer box 21 (referring to the side containing the positioning block 246), and the volume is changed according to the capacity of the transmitted gas through the gas storage box 241 and the telescopic box 242, so that the gas can fully fill the gas storage box 241 and the telescopic box 242.

[0072] When the gas is discharged after completing the heat exchange, the spring 252 in the elastic component 25 will play a role, and the spring 252 will be stretched when the telescopic box 242 is deformed. When the gas is discharged, the spring 252 contracts and relies on its elastic restoring force to restore the telescopic box 242 to its initial state.

[0073] Among them, as the gas cylinder delivers the corresponding amount of gas to the gas storage box 241 and the telescopic box 242 (the gas cylinder is equipped with a metering valve and a gas emission monitoring instrument, and when the output of the corresponding amount of gas is completed, the metering valve will be closed), since the gas is released into the gas storage box 241 and the telescopic box 242 in a compressed state, the generated gas has a lower temperature, and then the controller controls the exhaust fan 23 to start, and the exhaust fan 23 begins to absorb the air in the outer box 21, so that the outside air enters the outer box 21 from the vent 212 due to the negative pressure, thereby realizing the continuous circulation of the outside air in the outer box 21, and the conduction component 26 in the cold and heat exchange component 24, its conduction rod 261 is composed of alternately connected solid rods and elastic corrugated rods, and the hollow sleeve blocks 262 on the outer circumference of the solid rods are mutually sleeved from small to large, which increases the contact area and heat exchange efficiency between the cooling gas and the outside air, thereby utilizing the area effect of heat conduction and the principle of difference in thermal conductivity of materials, and the cold gas of the gas is transferred to the gas storage box 241 and the telescopic box 242 (the gas storage box 241 and the telescopic box 242 are made of materials with good heat and cold conductivity: such as metal materials, carbon-based materials and composite materials), so that when the outside air and the air in the outer box circulate, the cold flow transmitted by the cooling gas in the heat exchange component will be taken away together, thereby realizing the heating operation of the cooling gas, so that the cooling gas is heated to the ambient temperature. The gas storage box 241 and the telescopic box 242 are provided with a temperature detector (the temperature detector is a prior art, so it is not drawn in the figure). When the temperature detector detects that the gas returns to normal temperature, it will feedback a signal to the controller, thereby causing the controller to open the gas supply one-way solenoid valve 422, so that the gas enters the gas module diversion mechanism 3. The gas enters the gas module diversion mechanism 3 because the telescopic box 242 is elastic and combined with the elasticity of the stretched spring 252, and then when the gas supply one-way solenoid valve 422 is opened, it will enter the gas module diversion mechanism 3 through the connecting pipe 244 and the outlet pipe 213.

[0074] Step 2: The heated gas enters the module diversion mechanism 3 (the power of the gas module diversion mechanism 3 comes from the small suction pump built into the main valve 31, which can further improve the absorption of the gas in the gas storage box 241 and the telescopic box 242, and the main valve 31 can limit the minimum gas type of gas transmission according to the process requirements of gas mixing. For example, in production, at least two specific gases are required to participate in mixing. The main valve 31 can ensure that two or more gases enter the subsequent mixing barrel 45. The number of auxiliary valves 33 added is closely related to the number of gas pressure relief mechanisms 2 and is determined by the gas type). The main valve 31 has at least two input ends and one output end, and its output end is connected to the input pipe 423 of the gas input and output assembly 42. The buckles 32 on both sides can clamp the auxiliary valve 33 as needed. The auxiliary valve 33 is connected to the main valve 31 through a pipeline, and the connecting seat 311 of the main valve 31 and the auxiliary valve 33 input end is connected to the outlet pipe 213 of the gas pressure relief mechanism 2 (the gas received by the auxiliary valve 33 will converge into the main valve 31).

[0075] Among them, the main valve 31 allows the gas to enter the porous exhaust pipe 451 in the mixing barrel 45 through the input pipe 423, the gas transmission one-way solenoid valve 422, the diverter 421 and the branch pipe 426, thereby realizing multi-path transmission;

[0076] The gas supply one-way solenoid valve 422 and the exhaust one-way solenoid valve 424 have three different working states:

[0077] When gas is input into the mixing barrel 45, the gas supply one-way solenoid valve 422 is opened, and the exhaust one-way solenoid valve 424 is closed;

[0078] When the gas is completely input into the mixing barrel 45, the gas delivery one-way solenoid valve 422 is completely closed;

[0079] When the gas is mixed and needs to be discharged from the mixing barrel 45, the gas supply one-way solenoid valve 422 is closed and the exhaust one-way solenoid valve 424 is opened.

[0080] Special note: The gas supply one-way solenoid valve 422 and the exhaust one-way solenoid valve 424 are both a combination of a one-way valve and a solenoid valve. When the solenoid valve is opened, the gas can only flow in the gas supply direction of the one-way valve, and the reverse airflow is cut off by the one-way valve. When the solenoid valve is closed, the one-way valve gas path will be completely cut off.

[0081] Among them, when the gas enters the porous exhaust pipe 451, since the porous exhaust pipe 451 is distributed at different positions, different types of gases are evenly distributed at various positions of the mixing barrel 45, increasing the contact opportunities between gases. When the gas enters the mixing barrel 45, the controller controls the vibration rod 43 to work, so that the vibration rod 43 vibrates. While the vibration rod 43 vibrates, the resonance ball 443 in the resonance component 44 will resonate with the vibration rod 43, and transmit the vibration wave to the mixing barrel 45 with the non-Newtonian liquid as the medium. The characteristics of the non-Newtonian liquid enable it to effectively transmit vibration energy and enhance the kinetic activity of gas molecules and the frequency of mutual collision.

[0082] At the same time, the controller synchronously controls the drive motor 49 to work, and the stirring rod 461 in the mixing and converging assembly 46 in the mixing barrel 45 rotates under the drive of the drive motor 49 (the speed of the drive motor 49 can be adjusted according to the type of gas mixture and the concentration of the gas), and while the stirring rod 461 rotates, it also drives the converging hoods 462 and the conical stirring wheel 463 at both ends to rotate synchronously. The converging hoods 462 at both ends can converge the gas dispersed in the mixing barrel 45 to the center to avoid stratification of gas types, and the conical stirring wheel 463 further enhances the convergence effect.

[0083] The converged gas is mixed and dispersed again by the agitator component 47 and the mixing component 48, thereby realizing a circulation process in which the gas continuously converges and disperses in the mixing barrel 45, achieving sufficient mixing of the gas, and making the converged gas contact with the agitator component 47 and the mixing component 48.

[0084] Among them, the stirring rod 461 also synchronously drives the stirring component 47 and the mixing component 48 to rotate, and the curved stirring piece 472 of the stirring component 47 is provided with an air hole 473, which can disrupt the flow direction of the gas during the rotation process, so that the gas forms a complex turbulent state. The concave mixing disk 483 and the convex mixing disk 484 of the mixing component 48 continuously cut and flip the gas under the action of the rotation of the stirring rod 461 and its own rotation, thereby realizing efficient mixing of the gas, so that the gas continuously undergoes a cycle of convergence and dispersion in the mixing barrel 45, and finally achieves sufficient mixing.

[0085] Among them, a thermal conductivity detector is provided in the mixing barrel 45. Since it detects whether the gas in the mixing barrel 45 is mixed, when the thermal conductivity detector contacts the gas and the mixing is completed, the thermal conductivity detector will feedback information to the controller so that the controller closes the gas supply one-way solenoid valve 422 and opens the exhaust one-way solenoid valve 424, so that the mixed gas enters the next process through the exhaust pipe 425, and the next process contains an air pump for absorbing the gas in the mixing barrel 45.
