Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation technology, and more specifically, to a microbial fermentation flow stabilization device. Background Technology

[0002] Microbial fermentation flow stabilization equipment is a specialized device used to control and maintain the stability of fluid flow during microbial fermentation. In microbial fermentation processes, in order to ensure a stable growth environment for microorganisms and improve product yield and quality, it is necessary to precisely control various parameters within the fermenter, including the flow control of fluids (such as culture medium, air, or other gases). It can precisely control the flow rate of liquids or gases flowing into the fermenter, ensuring stability during the fermentation process, optimizing fermentation conditions, and improving production efficiency and product quality. It is widely used in biopharmaceuticals, food processing, and agricultural chemical production.

[0003] Chinese Patent Publication No. CN222294037U discloses a flow-stabilizing device for microbial fermentation, including a fermentation chamber. A feed pipe is connected through and fixedly to the top right side of the fermentation chamber. A pulverizing chamber is fixedly connected to the top right side of the inner wall of the fermentation chamber. Two fixed shafts are connected through and rotatably to the front and rear sides of the inner wall of the pulverizing chamber. The outer ring of each fixed shaft is fixedly connected with evenly distributed pulverizing teeth. A second motor is fixedly connected to the front side of the pulverizing chamber, and the output end of the second motor is fixedly connected to the fixed shafts. Gears are fixedly connected to the rear side of the outer ring of each fixed shaft, and the two gears are meshed. In this invention, fermentation raw materials are put into the fermentation chamber through the feed pipe. The second motor drives the fixed shafts and pulverizing teeth to pulverize the fermentation raw materials. Then, the pulverized raw materials are screened through a sieve plate, thereby accelerating the microbial fermentation speed.

[0004] In practical applications, existing technologies often encounter problems. During microbial fermentation, gases are produced. When gases or liquids are continuously added through pipes, the gases produced during fermentation can easily flow back through the pipes (i.e., backflow). Backflow can lead to contamination of the supply medium by byproducts of fermentation, thereby affecting the quality of the culture medium or the composition ratio of gases, and consequently the fermentation effect. Therefore, a microbial fermentation flow stabilization device is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a microbial fermentation flow stabilization device. It connects a gas input pipe and a liquid input pipe via a three-way connector, enabling separate input of gas and liquid. When gas is input, the pressure of the gas flow pushes a blocking ball to move, causing the telescopic rod and spring to extend. At this point, the blocking ball and the blocking ring change from a tightly fitted state to a separated state, allowing gas to enter the fermentation tank through the three-way connector. When gas supply stops, the blocking ball automatically resets under the action of the spring, blocking the blocking ring. Liquid is input in the same way, avoiding cross-contamination and ensuring a stable supply of a single medium. An electric push rod drives an adjusting plate to move within an adjusting frame, changing the flow area at the connection between the three-way connector and the fermentation tank, adjusting the flow rate of gas or liquid, maintaining the hydrodynamic stability of the fermentation broth, and adapting to the fermentation needs at different stages.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A microbial fermentation flow stabilization device includes a fermentation tank with an observation window embedded in it. A rotating rod is rotatably connected to the center of the fermentation tank's inner cavity. Multiple stirring rods are symmetrically fixed to the outer surface of the rotating rod. A three-way pipe is connected to the upper surface of the fermentation tank. A gas inlet pipe and a liquid inlet pipe are respectively connected to the other two ends of the three-way pipe. A blocking ring is fixedly connected to the inner cavity of each of the other two ends of the three-way pipe. A blocking ball is abutted against the inner cavity of the blocking ring. A connecting plate is symmetrically fixed to the outer surface of the blocking ball. A telescopic rod is fixedly connected between the connecting plate and the blocking ring. A spring is sleeved on the outer surface of the telescopic rod. An adjusting frame is connected to the outer surface of the lower end of the three-way pipe. An adjusting plate is movably connected to the adjusting frame and the inner cavity of the three-way pipe.

[0010] Furthermore, multiple support legs are uniformly fixedly connected to the lower surface of the fermentation tank, and the observation window is made of transparent material with scale lines marked on its outer surface.

[0011] Furthermore, the upper surface of the fermentation tank is connected to a feed pipe, and the lower outer surface of the fermentation tank is connected to a discharge pipe, on which a valve is installed.

[0012] Furthermore, a motor is fixedly connected to the middle of the upper surface of the fermentation tank, and the output shaft of the motor passes through the fermentation tank and is fixedly connected to the rotating rod.

[0013] Furthermore, both the outer surfaces of the plugging ring and the plugging ball are covered with sealing gaskets, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the plugging ring.

[0014] Furthermore, a sealing gasket is fixedly wrapped around the outer surface of the adjusting plate, a side plate is fixedly connected to the upper surface of the fermentation tank, an electric push rod is fixedly connected to one side of the side plate, and the output shaft end of the electric push rod passes through the adjusting frame and is fixedly connected to the adjusting plate.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This scheme connects the gas input pipe and the liquid input pipe through a three-way pipe to achieve separate input of gas and liquid. When gas is input, the pressure of the gas flow will push the blocking ball to move and drive the telescopic rod and spring to extend. At this time, the blocking ball and the blocking ring will change from a tightly fitted state to a separated state. Then the gas will enter the fermentation tank through the three-way pipe. When the gas supply stops, the blocking ball will automatically reset under the action of the spring and block the blocking ring. The liquid is also input in the same way, which can avoid cross-contamination and ensure a stable supply of a single medium. The electric push rod drives the adjustment plate to move in the adjustment frame, changing the flow area at the connection between the three-way pipe and the fermentation tank, adjusting the flow rate of gas or liquid, maintaining the hydrodynamic stability of the fermentation liquid, and adapting to the fermentation needs at different stages.

[0018] (2) This scheme starts the motor and drives the rotating rod to rotate through the output shaft, which drives the stirring rod to stir the fermentation raw materials evenly, ensuring that the raw materials are fully mixed with nutrients and gases, improving the efficiency of microorganisms in contact with oxygen and nutrients, and improving the quality of fermentation.

This embodiment provides a microbial fermentation stable flow device, including a fermentation tank 1, an observation window 101 is embedded and fixed on the fermentation tank 1, a rotating rod 2 is rotatably connected to the middle of the inner cavity of the fermentation tank 1, and a plurality of stirring rods 3 are symmetrically fixedly connected to the outer surface of the rotating rod 2.

[0030] Specifically, multiple support legs 102 are evenly fixedly connected to the lower surface of the fermentation tank 1. The observation window 101 is made of transparent material and has scale lines marked on its outer surface. The upper surface of the fermentation tank 1 is connected to the feed pipe 103. The lower outer surface of the fermentation tank 1 is connected to the discharge pipe 104. A valve 105 is installed on the discharge pipe 104. A motor 4 is fixedly connected to the middle of the upper surface of the fermentation tank 1. The output shaft of the motor 4 passes through the fermentation tank 1 and is fixedly connected to the rotating rod 2.

[0031] Furthermore, the fermentation tank 1, as the main container for fermentation, is supported on the ground by the support legs 102, and the raw materials to be fermented are transported into the fermentation tank 1 through the feed pipe 103. Then, the motor 4 is started and drives the rotating rod 2 to rotate through the output shaft, which drives the stirring rod 3 to stir the fermentation raw materials evenly, ensuring that the raw materials are fully mixed with nutrients and gases, and improving the efficiency of microorganisms in contacting oxygen and nutrients.

[0032] The observation window 101 is made of transparent material (such as tempered glass) to observe the liquid level, color and foam of the fermentation broth in real time. The scale line assists in quantitative monitoring. The feed pipe 103 and the discharge pipe 104 are used to add the initial culture medium and discharge the fermentation products, respectively. The valve 105 controls the discharge flow rate.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The upper surface of the fermentation tank 1 is connected to a three-way pipe 5. The other two ends of the three-way pipe 5 are respectively connected to a gas input pipe 6 and a liquid input pipe 7. The inner cavities of the other two ends of the three-way pipe 5 are fixedly connected to a blocking ring 8. The inner cavity of the blocking ring 8 abuts against a blocking ball 9. The outer surface of the blocking ball 9 is symmetrically fixedly connected to a connecting plate 10. A telescopic rod 11 is fixedly connected between the connecting plate 10 and the blocking ring 8. A spring 12 is sleeved on the outer surface of the telescopic rod 11. The lower outer surface of the three-way pipe 5 is connected to an adjusting frame 13. The adjusting frame 13 and the inner cavity of the three-way pipe 5 are movably connected to an adjusting plate 14.

[0035] Specifically, the outer surfaces of the blocking ring 8 and the blocking ball 9 are both covered with sealing gaskets. One end of the spring 12 is fixedly connected to the connecting plate 10, and the other end of the spring 12 is fixedly connected to the blocking ring 8. The outer surface of the adjusting plate 14 is covered with a sealing gasket. The upper surface of the fermentation tank 1 is fixedly connected to the side plate 15. An electric push rod 16 is fixedly connected to one side of the side plate 15. The output shaft end of the electric push rod 16 passes through the adjusting frame 13 and is fixedly connected to the adjusting plate 14.

[0036] Furthermore, the fermentation tank 1 is connected to a gas input pipe 6 and a liquid input pipe 7 via a three-way pipe 5, enabling separate input of gas (such as air / oxygen) and liquid (such as culture medium, buffer solution). When gas is input, the pressure of the gas flow pushes the blocking ball 9 to move, causing the telescopic rod 11 and spring 12 to extend. At this time, the blocking ball 9 and the blocking ring 8 change from a tightly fitted state to a separated state, and the gas enters the fermentation tank 1 through the three-way pipe 5. When the gas supply stops, the blocking ball 9 automatically resets under the action of the spring 12, blocking the blocking ring 8. Liquid is also input in the same way, which can avoid cross-contamination and ensure a stable supply of a single medium.

[0037] The three-way pipe 5 is used to separate the input paths for gas and liquid, respectively delivering media such as oxygen and culture medium. When the plugging ring 8 and the plugging ball 9 are engaged by the sealing gasket, they form a tight seal to prevent leakage.

[0038] The operator drives the adjusting plate 14 to move within the adjusting frame 13 via the electric push rod 16, thereby changing the flow area at the connection between the three-way pipe 5 and the fermentation tank 1, adjusting the flow rate of gas or liquid, maintaining the hydrodynamic stability of the fermentation liquid, and adapting to the fermentation needs at different stages.

[0039] Working Principle: During operation, the fermentation tank 1, serving as the main fermentation container, is supported on the ground by support legs 102. The raw materials to be fermented are fed into the fermentation tank 1 through the feed pipe 103. Then, the motor 4 drives the rotating rod 2 to rotate via the output shaft, which in turn drives the stirring rod 3 to uniformly stir the fermentation materials, ensuring thorough mixing with nutrients and gases, thus improving the efficiency of microbial contact with oxygen and nutrients. The fermentation tank 1 is connected to a gas input pipe 6 and a liquid input pipe 7 via a three-way pipe 5, allowing for the separate input of gases such as air / oxygen and liquids such as culture medium and buffer solutions. When gas is input, the pressure of the gas flow pushes the blocking ball 9 to move. The movement causes the telescopic rod 11 and spring 12 to extend, at which point the blocking ball 9 and the blocking ring 8 change from a tightly fitted state to a separated state. At this time, the gas enters the fermentation tank 1 through the three-way pipe 5. When the gas supply stops, the blocking ball 9 automatically resets under the action of the spring 12, blocking the blocking ring 8. The liquid is also input in the same way, which can avoid cross-contamination and ensure a stable supply of a single medium. During use, the operator drives the adjusting plate 14 to move within the adjusting frame 13 through the electric push rod 16, changing the flow area at the connection between the three-way pipe 5 and the fermentation tank 1, adjusting the flow rate of gas or liquid, maintaining the hydrodynamic stability of the fermentation liquid, and adapting to the fermentation needs at different stages.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
