Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation technology, specifically to a microbial fermenter with an air intake treatment mechanism. Background Technology

[0002] A microbial fermenter is a process testing instrument used in the field of agronomy. The fermentation broth is pumped into the reactor and then mixed thoroughly in a mixer. It is then placed in an incubator for constant temperature incubation (generally around 40 degrees Celsius) for more than 48 hours to obtain highly active bacterial cultures or liquid bacterial cultures. After further purification, the bacterial solution is packaged into bacterial solutions of different concentrations by an aseptic filling machine for users.

[0003] In the prior art, patent document CN219259966U discloses a microbial fermenter, belonging to the field of industrial experimental instrument technology. It mainly includes a tank body, with a sampling seat installed at the upper end. An adjusting tube is connected to the inner bearing of the sampling seat, and a lifting tube is threadedly connected to the inner side of the adjusting tube. An outer tube is provided at the lower end of the sampling seat, and a guide portion is provided between the outer tube and the lifting tube. The guide portion restricts the circumferential rotation of the lifting tube. By rotating the adjusting tube, it achieves threaded transmission with the lifting tube. The lifting tube and outer tube are prevented from rotating by the guide portion, so that when the adjusting tube rotates, the lifting tube moves up and down along the axis of the adjusting tube through threaded transmission, thereby adjusting the position of the sampling inlet at the lower end of the lifting tube.

[0004] To address the inconvenience of sampling during the use of existing fermenters, current technology employs a combination of an adjusting pipe and a lifting pipe. This allows for convenient adjustment of the height of the lifting pipe's sampling inlet via threaded transmission and a guide. However, this method still presents the challenge of controlling the oxygen content inside the fermenter, making it difficult to guarantee whether microorganisms will undergo anaerobic respiration, thus reducing the practicality of the fermenter.

[0017] By adopting the above technical solution, the combination of isolation plate and heating tube can facilitate the heating of oxygen.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0028] The present invention will be further described in detail below with reference to embodiments: Example

[0029] like Figure 1-6 As shown, this utility model provides a microbial fermenter with an air intake treatment mechanism, including a fermentation unit 1; an air supply unit 2 disposed on the outer surface of the fermentation unit 1 for air supply; and a control distribution box 3 disposed on the outer surface of the fermentation unit 1 for power distribution control. The fermentation unit 1 includes a fermentation component and a pressure relief component 15 disposed on the outer surface of the fermentation component. The air supply unit 2 includes an air supply component disposed on the outer surface of the fermentation unit 1 and a heating component disposed on the outer surface of the air supply component. The fermentation component includes a support base 11, and a tank body 12 is fixedly connected to the inner wall of the support base 11. An injection pipe and a sampling pipe are disposed on the top of the tank body 12. A heating chamber is disposed inside the tank body 12, and a heater 13 is disposed inside the heating chamber. A stirring device 14 is detachably connected to the upper surface of the tank body 12. A stirring blade that is rotatably connected to the driving end of the stirring device 14 is fixedly connected to the inner wall of the tank body 12. The pressure relief component 15 includes a pressure relief pipe 1. 51. The outer surface of the pressure relief pipe 151 is fixedly connected to the top of the tank 12. A fixing plate 152 is fixedly connected to the inner wall of the pressure relief pipe 151. A spring column 153 is fixedly connected to the upper surface of the fixing plate 152. A pressure relief plug 154, which is slidably connected to the inner wall of the pressure relief pipe 151, is fixedly connected to the top of the spring column 153. When using the microbial fermentation tank, the culture medium containing microorganisms is first injected into the tank 12. The heater 13 is then activated to heat the water in the internal cavity of the tank 12. At the same time, a thermometer installed inside the tank 12 is used to detect temperature changes. The stirring device 14 is then activated to slowly stir and mix the culture medium. During the microbial fermentation process, aerobic respiration occurs, and the gas produced increases the internal pressure of the tank 12. Therefore, due to the pressure, the pressure relief plug 154 is driven to slide out of the pressure relief pipe 151 under the limitation of the spring column 153 and the fixing plate 152, thus facilitating pressure relief. Example

[0030] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the gas delivery assembly includes a mounting bracket 21, the outer surface of the mounting bracket 21 is fixedly connected to the outer surface of the support base 11, an oxygen tank 22 is detachably connected to the inner wall of the mounting bracket 21, a solenoid valve 23 is detachably connected to the output end of the oxygen tank 22, a connecting pipe 24 is fixedly connected to the top of the solenoid valve 23, and the heating assembly includes a heating box 25, the input end of the heating box 25 is connected to the connecting pipe 24, and an isolation plate 28 is fixedly connected to the inner wall of the heating box 25. The outer surface is detachably connected to a heating tube 29, and the output end of the heating box 25 is detachably connected to a one-way valve 26. The output end of the one-way valve 26 is fixedly connected to a gas supply pipe 27 that communicates with the inside of the tank 12. When it is necessary to inject oxygen into the tank 12, the oxygen is input into the heating box 25 by activating the solenoid valve 23 in conjunction with the connecting pipe 24. Then, the heating tube 29 is activated, and with the guidance of the isolation plate 28, the oxygen is heated. Finally, the oxygen is delivered to the inside of the tank 12 through the cooperation of the one-way valve 26 and the gas supply pipe 27, which is conducive to the fermentation of microorganisms.

[0031] The working principle of this microbial fermenter with an air intake treatment mechanism will be explained in detail below.

[0032] like Figure 1-6 As shown, when using a microbial fermenter, the culture medium containing microorganisms is first injected into the tank 12, and the heater 13 is activated to heat the water in the internal cavity of the tank 12. At the same time, the temperature change is detected by a thermometer installed inside the tank 12, and the stirring device 14 is activated to slowly stir and mix the culture medium. During the microbial fermentation process, aerobic respiration occurs, and the gas produced increases the internal pressure of the tank 12. Therefore, due to the pressure, the pressure relief plug 154 is driven to slide out of the pressure relief pipe 151 under the limit of the spring column 153 and the fixing plate 152, so as to facilitate pressure relief. When it is necessary to inject oxygen into the tank 12, the solenoid valve 23 is activated in conjunction with the connecting pipe 24 to input oxygen into the heating box 25. Then, the heating pipe 29 is activated, and with the guidance of the isolation plate 28, the oxygen is heated. Finally, the oxygen is delivered to the inside of the tank 12 through the cooperation of the one-way valve 26 and the gas supply pipe 27, which is conducive to the fermentation of microorganisms.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
