Description

Technical Field

[0001] This utility model belongs to the technical field of protein production equipment, specifically relating to a protein raw material gas mixing device. Background Technology

[0002] In the process of microbial fermentation for protein synthesis, the precise supply of raw gas is a core element in ensuring fermentation efficiency and product quality. These raw gases mainly include gaseous substances such as carbon dioxide, carbon monoxide, hydrogen, and methane. As key carbon and energy sources for microbial metabolism, their mixing ratio directly affects the growth rate, metabolic pathways, and protein synthesis efficiency of the microorganisms. Carbon dioxide and methane provide the carbon source for microbial metabolism, while hydrogen and carbon monoxide participate in metabolic reactions as energy sources. These gases must be mixed in specific proportions before being introduced into the fermentation system to provide a suitable material basis and energy source for microbial growth, reproduction, and protein synthesis.

[0003] However, existing devices rely on manual control of the amount of raw material gas entering the gas mixing tank. This method, which requires operators to control the gas volume based on experience, makes it difficult to control the flow rate of each gas. Operational errors and visual judgment biases can easily cause fluctuations in the proportion of each raw material gas entering the mixing tank, causing the gas ratio to deviate from the optimal range required for microbial fermentation. This, in turn, affects the metabolic efficiency of microorganisms, makes it impossible to guarantee the stability of the fermentation process, and ultimately affects the yield and quality of protein synthesis. Utility Model Content

[0004] The purpose of this utility model is to provide a protein raw material gas mixing device, including a gas mixing tank, which has several air inlet pipes at the top, each air inlet pipe is equipped with a flow sensor, and a gas filter component and a flow control component are connected to the air inlet pipe. A gas mixing component is installed inside the gas mixing tank.

[0005] The gas mixing assembly includes several parallel gas dispersion plates, with an impeller rotatably mounted between two adjacent gas dispersion plates.

[0006] The flow control component includes a valve body with a first valve port and a second valve port inside. A sleeve is fixed inside the valve body, and a rod is slidably installed inside the sleeve. A first valve plug and a second valve plug are installed on the rod, located at the first valve port and the second valve port, respectively. A push plate is provided at one end of the rod, and a compression spring is installed on the rod. The two ends of the compression spring are fixed to the sleeve and the push plate, respectively. A cam is rotatably installed on one side of the push plate. An arc-shaped groove is provided on the surface of the push plate, and the wheel surface of the cam is located in the arc-shaped groove. By rotating the cam, the first valve plug and the second valve plug on the rod are moved, thereby opening and closing the first valve port and the second valve port.

[0007] Furthermore, the valve body is tubular, with an inlet flange and an outlet flange at each end. The inlet flange is connected to the filter assembly, and the outlet flange is connected to the inlet pipe at the top of the gas mixing tank.

[0008] Furthermore, a number of fixing rods are fixed on the inner wall of the valve body, and the fixing rods extend radially along the axis of the valve body, with the sleeve fixedly installed in the middle of the fixing rods.

[0009] Furthermore, a circular hole is provided on the side wall of the valve body, and a rotating rod is rotatably installed in the circular hole. The central axis of the rotating rod is perpendicular to the central axis of the valve body. A cam is installed at one end of the rotating rod, and a servo motor is connected to the other end of the rotating rod. The servo motor is located outside the valve body.

[0010] Furthermore, the gas mixing tank is cylindrical in shape with a hollow cavity structure inside. Several legs are installed on the gas mixing tank, and each leg is equipped with a caster at its bottom, with a locking mechanism on the caster.

[0011] Furthermore, the aforementioned intake pipes are linearly and uniformly distributed along the circumference of the gas mixing tank, and an exhaust pipe is installed at the bottom of the gas mixing tank, forming a top-to-bottom airflow path with the top intake pipe.

[0012] Furthermore, each gas dispersion plate has multiple small holes evenly distributed, and each gas dispersion plate has a circular perforation in the middle. A stirring rod passes through the circular perforation, and several impellers are fixedly installed on the stirring rod. A drive motor is connected to the top of the stirring rod, and the drive motor is located at the top of the gas mixing tank.

[0013] Furthermore, the gas filtration assembly includes a filter housing, which is tubular with an inlet flange and an outlet flange at both ends. The inlet flange is connected to the raw material gas tank and the inlet pipeline, and the outlet flange is connected to the inlet flange of the valve body.

[0014] Furthermore, inside the filter housing, a first filter layer, a second filter layer, and a third filter layer are sequentially arranged along the gas flow direction. The first filter layer is a metal wire mesh, the second filter layer is an activated carbon layer, and the third filter layer is a polytetrafluoroethylene membrane.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: By connecting various raw material gas tanks to be mixed with corresponding gas filtration components, each type of raw material gas first enters the filtration component. The raw material gas is filtered sequentially through three filter layers within the filtration component. The filtered raw material gas then enters the flow control component. In the flow control component, in conjunction with a flow sensor and control system, a servo motor drives a cam to rotate, causing the sleeve rod and the first and second valve plugs to move axially along the valve body, adjusting the flow rate of each raw material gas through the first and second valve ports, thereby controlling the proportion of gas entering the gas mixing tank. The flow-regulated raw material gas flows into the gas mixing tank from the top and contacts multiple gas dispersion plates. Through small holes in the gas dispersion plates, it is progressively divided into fine airflows. Simultaneously, the drive motor rotates the stirring rod and the impeller inserted between the gas dispersion plates, uniformly mixing the gas. Finally, the uniformly mixed gas is discharged from the outlet pipe at the bottom of the tank. This provides a uniformly composed raw material gas for subsequent protein synthesis processes.

[0016] This invention effectively removes impurities from the raw material gas through a three-layer filter, preventing impurities from interfering with microbial metabolism. Real-time monitoring by a flow sensor, combined with a flow control component, allows for control of the proportion of each raw material gas entering the mixing tank, solving the problem of ratio fluctuations caused by reliance on manual experience in existing devices and ensuring that the gas ratio always meets the optimal requirements for microbial fermentation. The multi-layer gas dispersion plate and the rotating impeller agitate the mixture, resulting in more uniform mixing and improved fermentation efficiency, protein yield, and quality.

Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0024] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] See Figure 1 As shown, this utility model provides a gas mixing device for protein raw materials, including a gas mixing tank 101. The gas mixing tank 101 is cylindrical in shape and has a hollow cavity structure inside. The tank wall of the gas mixing tank 101 is made of high-strength corrosion-resistant material, which can withstand the pressure and chemical corrosion during the gas mixing process. Several support legs 102 are installed on the gas mixing tank 101, and each support leg 102 is equipped with a caster 103 at its bottom, and the caster 103 is provided with a locking structure.

[0026] The gas mixing tank 101 has several inlet pipes 104 at its top, which are linearly and evenly distributed along the circumference of the tank to ensure that different raw materials gases can diffuse outwards after entering from the top. Each inlet pipe 104 is connected to a gas filter assembly and a flow control assembly. An outlet pipe 105 is installed at the bottom of the gas mixing tank 101, forming a top-to-bottom airflow path with the top inlet pipes 104. A control valve is installed at the outlet pipe 105 to control the outflow of the mixed gas. A gas mixing assembly is built into the gas mixing tank 101.

[0027] See Figure 2-3 As shown, the gas mixing assembly includes several parallel gas dispersion plates 201, which are horizontally fixed inside a gas mixing tank 101. Each gas dispersion plate 201 has multiple small holes evenly distributed on it. A drive motor 202 is connected to the top center of the gas mixing tank 101. A stirring rod 203 is connected to the output shaft of the drive motor 202. A circular perforation is provided in the center of each gas dispersion plate 201, and the stirring rod 203 passes through these circular perforations sequentially from top to bottom. Several impellers 204 are fixedly mounted on the stirring rod 203, distributed along the axial direction of the stirring rod 203, and interspersed between the gas dispersion plates 201.

[0028] Different types of raw gas enter from the top of the gas mixing tank 101 and are dispersed layer by layer by the multi-layer perforated gas dispersion plates 201. At the same time, the drive motor 202 drives the stirring rod 203 and the impeller 204 interspersed between the dispersion plates to rotate, creating disturbance to the gas and enhancing gas convection and diffusion. Finally, the uniformly mixed gas is discharged from the gas outlet pipe 105 at the bottom of the gas mixing tank 101.

[0029] See Figure 4As shown, the gas filtration assembly includes a filter housing 301, which is tubular with an inlet flange and an outlet flange at both ends. The inlet flange connects to a raw gas tank and an inlet pipe 104, while the outlet flange connects to a flow control component. Inside the filter housing 301, a first filter layer, a second filter layer, and a third filter layer are sequentially arranged along the gas flow direction. The first filter layer is a metal mesh 302, located near the inlet flange. The metal mesh 302 can intercept large particulate impurities in the gas. The second filter layer is an activated carbon layer 303, located downstream of the metal mesh 302. The activated carbon layer 303 can adsorb odors such as sulfides and some organic impurities in the gas. The third filter layer is a polytetrafluoroethylene (PTFE) membrane 304, located near the outlet flange. The PTFE membrane 304 can effectively intercept micron-sized fine particles in the gas, and due to its excellent chemical resistance and hydrophobicity, it can also block water vapor and some corrosive small molecule impurities. The filtered raw gas flows into the gas mixing tank 101 through the flow control component.

[0030] See Figure 5 As shown, the flow control assembly includes a valve body 401, which is tubular with an inlet flange and an outlet flange at both ends. The inlet flange connects to the outlet flange of the filter housing 301, and the outlet flange connects to the inlet pipe 104 at the top of the gas mixing tank 101. The valve body 401 contains a first valve port 402 and a second valve port 403, located on one side of the outlet flange. A reflux zone exists between the first valve port 402 and the second valve port 403.

[0031] Several fixing rods 404 are fixed on the inner wall of the valve body 401. The fixing rods 404 extend radially along the axis of the valve body 401. A sleeve 405 is fixed in the middle of the fixing rods 404. The sleeve 405 is coaxial with the valve body 401. A sleeve rod 406 is sleeved inside the sleeve 405. The sleeve rod 406 can slide along the axial direction of the sleeve 405 (along the length direction of the valve body 401). A first valve plug 407 and a second valve plug 408 are provided on the sleeve rod 406. The first valve plug 407 and the second valve plug 408 are located at the first valve port 402 and the second valve port 403, respectively. They can move with the sleeve rod 406 to open and close the first valve port 402 and the second valve port 403.

[0032] A circular push plate 409 is provided at one end of the sleeve rod 406. A compression spring 410 is installed on the sleeve rod 406. One end of the compression spring 410 is fixed to the sleeve 405, and the other end of the compression spring 410 is fixed to the push plate 409. A cam 411 is installed at the other end of the push plate 409. An arc-shaped groove is provided on the surface of the push plate 409. The wheel surface of the cam 411 is located in the arc-shaped groove. When the cam 411 rotates, the wheel surface of the cam 411 can move along the arc-shaped groove.

[0033] A through hole is provided on the side wall of the valve body 401, and a rotating rod 412 is rotatably mounted in the through hole. The central axis of the rotating rod 412 is perpendicular to the central axis of the valve body 401. A cam 411 is mounted on one end of the rotating rod 412, and the other end of the rotating rod 412 extends outward through the side wall of the valve body 401. The penetration point between the rotating rod 412 and the side wall of the valve body 401 is sealed. A servo motor 413 is fixedly mounted on the outside of the valve body 401, and the output shaft of the servo motor 413 is connected to the rotating rod 412. By controlling the operation of the servo motor 413, the rotating rod 412 and the cam 411 can be rotated.

[0034] When the flow control component is in the off state, the highest position of the cam 411 wheel surface contacts the push plate 409, the compression spring 410 is compressed, and the sleeve rod 406 drives the first valve plug 407 and the second valve plug 408 to press tightly against the first valve port 402 and the second valve port 403 respectively, completely blocking the gas flow channel and preventing the airflow from passing through.

[0035] When an increase in gas flow is required, the servo motor 413 drives the cam 411 to rotate, causing the lowest position of the cam 411 wheel surface to gradually contact the push plate 409. During this process, the spring gradually releases its elastic force, and the push plate 409 and the sleeve rod 406 move axially along the valve body 401 under the action of the elastic force, causing the first valve plug 407 and the second valve plug 408 to move away from the first valve port 402 and the second valve port 403 respectively. The gap between the valve port and the valve plug increases, thereby allowing the gas to pass through smoothly.

[0036] When it is necessary to reduce the gas flow rate, the servo motor 413 drives the cam 411 to rotate, so that the highest position of the cam 411 wheel surface gradually contacts the push plate 409. The first valve plug 407 and the second valve plug 408 gradually approach the first valve port 402 and the second valve port 403 with the sleeve rod 406, reducing the cross-sectional area for gas flow until they are closed, thus blocking the airflow.

[0037] In addition, a flow sensor is installed inside the air inlet pipe 104, and a control system is installed on the gas mixing tank 101. The flow sensor monitors the flow rate of each raw material entering the gas mixing tank 101 and transmits the monitored flow signal to the control system. The control system controls the operation of the servo motor 413, thereby controlling the gas flow rate. This ensures that the gas ratio entering the gas mixing tank 101 meets the requirements of microbial fermentation.

[0038] Example: Various raw material gas tanks to be mixed are connected to their corresponding gas filtration components, allowing each type of raw material gas to enter the filtration components first. The raw material gas is filtered sequentially through three filter layers within the filtration components. The filtered raw material gas then enters the flow control component. In the flow control component, in conjunction with a flow sensor and control system, a servo motor 413 drives a cam 411 to rotate, causing a sleeve rod 406 and the first and second valve plugs 408 to move axially along the valve body 401, adjusting the flow rate of each raw material gas through the first valve port 402 and the second valve port 403, thereby controlling the proportion of gas entering the gas mixing tank 101. The flow-regulated raw material gas flows into the gas mixing tank 101 from the top and contacts the multi-layer gas dispersion plates 201. Through the small holes on the gas dispersion plates 201, it is progressively divided into fine airflows. Simultaneously, the drive motor 202 rotates the stirring rod 203 and the impeller 204 inserted between the gas dispersion plates 201, uniformly mixing the gas. Finally, the uniformly mixed gas is discharged from the outlet pipe 105 at the bottom of the tank. It provides uniformly composed feed gas for subsequent protein synthesis processes.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
