Description

Technical Field

[0001] The utility model belongs to the field of microbial culture equipment, and particularly relates to a microbial culture seed tank with a variable sealing structure. Background Art

[0002] A microbial culture seed tank is a device used for the expansion culture of microbial strains and seeds in the microbial fermentation process. There are many disadvantages in the current microbial culture seed tank. First of all, due to the lack of a variable sealing structure, the sealing degree of the seed tank is fixed and cannot be flexibly adjusted according to different requirements during the culture process. In the initial stage of microbial culture, better gas exchange is required to meet the oxygen demand of microorganisms. However, the ventilation volume of the fixed-sealed seed tank is limited, and efficient gas exchange cannot be carried out because the sealing structure cannot be changed, which limits the gas inlet and outlet volume. In response to this, the conventional solution is to increase the ventilation pipeline and valve to increase the ventilation volume. However, this will increase the complexity and cost of the tank body structure, and too many pipelines and valves are prone to leakage and contamination risks. Therefore, a new structure needs to be proposed to solve the above technical problems. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a microbial culture seed tank with a variable sealing structure to solve the problems proposed in the above background art.

The inner tank is installed inside the seed tank body. The sealing cover is hinged on the upper surface of the seed tank body. An air outlet pipe is installed on the upper surface of the seed tank body. An air inlet pipe is installed on the outer surface of the seed tank body. A sealing component is installed inside the seed tank body. The sealing component includes: a sealing pipe, a fan, a mounting rack, a sealing baffle, and an electric push rod. A fan is installed inside the sealing pipe. A baffle is installed through the end of the sealing pipe far from the seed tank body. An electric push rod is installed on the upper surface of the sealing pipe through the mounting rack. A cooling plate is installed inside the inner tank. A heating sleeve is installed on the inner wall of the seed tank body.

[0005] As a preferred embodiment, a support leg is respectively installed at each of the four corners of the lower surface of the seed tank body. The sealing cover is hinged at the central position of the upper surface of the seed tank body. A sealing gasket is provided at the connection between the sealing cover and the seed tank body.

[0006] As a preferred embodiment, a temperature sensor is installed on the upper side surface inside the seed tank body. An inner tank with a U-shaped cross-section is installed at the bottom inside the seed tank body. Cooling plates are installed on the inner wall and the bottom of the inner tank. A heating sleeve is installed at the central position of the inner wall of the seed tank body. The heating sleeve can quickly transfer heat to the inner tank and the culture inside, enabling the culture environment to rapidly reach the appropriate temperature required for microbial growth, shortening the preparation time before cultivation. At the same time, when the temperature is too high during the cultivation process, the cooling plates can quickly absorb heat and reduce the temperature of the culture environment, achieving precise control of the temperature and helping to maintain suitable growth temperature conditions for the microorganisms.

[0007] As a preferred embodiment, the end of the intake pipe away from the seed tank body is connected to a filtered air device. Check valves are provided at the connections of the outlet pipe and the intake pipe to the seed tank body. Sealing pipes are symmetrically installed on the outer surface of the seed tank body.

[0008] As a preferred embodiment, a sealing ring is provided at the connection of the sealing pipe to the seed tank body. A fan is installed inside the sealing pipe. The cross-section of the sealing pipe is in a square shape. A mounting bracket is installed on the outer surface of the end of the sealing pipe away from the seed tank body.

[0009] As a preferred embodiment, an electric push rod is installed on the upper side surface of the mounting bracket. The upper side surface of the sealing baffle is connected to the telescopic rod of the electric push rod. The sealing baffle is movably sealed inside the sealing pipe by the electric push rod. At different stages of microbial cultivation, the requirements for oxygen demand and gas exchange are different. In the initial cultivation stage, a large amount of air intake may be required to provide sufficient oxygen. At this time, the electric push rod pulls the sealing baffle to a large distance, and the fan accelerates gas exchange to meet the growth needs of the microorganisms. As the cultivation progresses, the ventilation volume may need to be reduced or the sealing strengthened. The electric push rod pushes the sealing baffle to close, adjusting the ventilation volume and creating a suitable micro-culture environment.

[0010] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By setting a sealing component, the sealing component is installed inside the seed tank body. The sealing component includes: a sealing pipe, a gas fan, a mounting rack, a sealing baffle, and an electric push rod. A gas fan is installed inside the sealing pipe. One end of the sealing pipe away from the seed tank body is installed with a baffle passing through. The upper side surface of the sealing pipe is installed with an electric push rod through the mounting rack. When in use, at different stages of microbial culture, the requirements for oxygen demand and gas exchange are different. In the initial culture stage, a large amount of air intake may be required to provide sufficient oxygen. At this time, the electric push rod pulls the sealing baffle to a large distance, and the gas fan accelerates gas exchange to meet the growth needs of microorganisms. As the culture progresses, the ventilation volume may need to be reduced or the sealing strengthened. The electric push rod pushes the sealing baffle to close, adjusts the ventilation volume, and creates a suitable culture microenvironment.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a microbial culture seed tank with a variable sealing structure, including: a seed tank body 100, a sealing cover 120, a sealing assembly 200 and an inner tank 300. An inner tank 300 is installed inside the seed tank body 100. A sealing cover 120 is hinged on the upper surface of the seed tank body 100. An air outlet pipe 130 is installed on the upper surface of the seed tank body 100. An air inlet pipe 140 is installed on the outer surface of the seed tank body 100. A sealing assembly 200 is installed inside the seed tank body 100. The sealing assembly 200 includes: a sealing pipe 210, an air fan 220, a mounting bracket 240, a sealing baffle 230 and an electric push rod 250. An air fan 220 is installed inside the sealing pipe 210. A baffle is installed through the end of the sealing pipe 210 far away from the seed tank body 100. An electric push rod 250 is installed on the upper surface of the sealing pipe 210 through a mounting bracket 240. A cooling plate 310 is installed inside the inner tank 300. A heating sleeve 320 is installed on the inner wall of the seed tank body 100.

[0021] Please refer to Figures 1 to 3 , as the first embodiment of the present invention: Support legs 110 are respectively installed at the four corners of the lower surface of the seed tank body 100. A sealing cover 120 is hinged at the central position of the upper surface of the seed tank body 100. A sealing gasket is provided at the connection between the sealing cover 120 and the seed tank body 100;

[0022] A temperature sensor is installed on the upper side surface inside the seed tank body 100. An inner tank 300 with a U-shaped cross-section is installed at the bottom inside the seed tank body 100. Cooling plates 310 are installed on the inner wall and bottom of the inner tank 300. A heating sleeve 320 is installed at the central position of the inner wall of the seed tank body 100;

[0023] One end of the air inlet pipe 140 away from the seed tank body 100 is connected to a filtered air device. Check valves are provided at the connections of the air outlet pipe 130 and the air inlet pipe 140 to the seed tank body 100. Sealing pipes 210 are symmetrically installed on the outer surface of the seed tank body 100;

[0024] When in use, the user first puts the seeds to be cultivated and the microbial culture solution into the bottom inside the seed tank body 100 through the sealing cover 120. After the seeds and the microbial culture solution are both placed, the user can close the sealing cover 120. At this time, the sealing cover 120 is hermetically connected to the seed tank body 100 through a sealing gasket. At this time, the user can open the sealing assembly 200 in a timely manner according to the sealing requirement to conduct a ventilation operation on the inside of the seed tank body 100 (note that the whole operation needs to be carried out in a sterile environment and at the same time ensure the sterility of the air). When the user needs to conduct an air intake or air release operation on the inside of the seed tank body 100, the user can operate through the air inlet pipe 140 and the air outlet pipe 130. The air inlet pipe 140 needs to introduce sterile air (realized through an air filtration device, which is prior art and will not be elaborated here). The air outlet pipe 130 needs to discharge the gas to the outside through a hose to prevent the discharged air from polluting the sterile operation environment. At the same time, the user can observe the cultivation temperature inside the seed tank body 100 according to the temperature sensor. Once the temperature exceeds or is lower than the set temperature, at this time, the cooling plate 310 or the heating sleeve 320 can work to perform heating and cooling operations. Since the heating sleeve 320 can quickly transfer heat to the inner tank 300 and the culture inside, the culture environment can quickly reach the appropriate temperature required for the growth of microorganisms, shortening the preparation time before cultivation. At the same time, when the temperature is too high during the cultivation process, the cooling plate 310 can quickly absorb heat and reduce the temperature of the culture environment, realizing precise control of the temperature and helping to maintain the appropriate growth temperature conditions for microorganisms.

[0025] Please refer to Figures 1 to 3 , as the second embodiment of the present utility model: A sealing ring is provided at the connection of the sealing pipe 210 to the seed tank body 100. A fan 220 is installed inside the sealing pipe 210. The cross-section of the sealing pipe 210 is in a square structure. A mounting bracket 240 is installed on the outer surface of one end of the sealing pipe 210 away from the seed tank body 100;

[0026] An electric push rod 250 is installed on the upper surface of the mounting frame 240, and the upper surface of the sealing baffle 230 is connected to the telescopic rod of the electric push rod 250. The sealing baffle 230 is movably sealed by the electric push rod 250 and arranged inside the sealing tube 210.

[0027] When in use, when the user needs to control the sealing environment, the user can start the electric push rod 250 to retract the telescopic rod of the electric push rod 250, so that the sealing baffle 230 is away from the sealing tube 210, so that the tube mouth of the sealing tube 210 is partially opened. When the telescopic rod of the electric push rod 250 is completely retracted, the sealing baffle 230 is completely pulled back by the electric push rod 250, so that the tube mouth of the sealing tube 210 is completely opened. The user can select the specific rising situation of the sealing baffle 230 according to the actual situation, so as to control the tube mouth of the sealing tube 210. diameter. After opening, the user can turn on the air fan 220 to exchange the air. Since the oxygen demand and gas exchange requirements are different at different stages of microbial culture, a large amount of air intake may be required to provide sufficient oxygen in the initial culture stage. At this time, the electric push rod 250 pulls the sealing baffle 230 apart a large distance, and the air fan 220 accelerates gas exchange to meet the growth needs of microorganisms. As the culture proceeds, it may be necessary to reduce the ventilation volume or strengthen the seal. The electric push rod 250 pushes the sealing baffle 230 to close, adjusts the ventilation volume, and creates a suitable culture microenvironment.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
