Description

Technical Field

[0001] The utility model belongs to the technical field of microbial fermentation, and in particular relates to a microbial fermentation gas transmission component for liquor saccharification. Background Art

[0002] During the saccharification process of liquor, although the gas transmission technology does not directly participate in the saccharification reaction, it has a profound impact on the fermentation process. In the early stage of fermentation, oxygen is necessary for microorganisms to carry out aerobic respiration, which helps to multiply and start metabolic activities of microorganisms. The oxygen content and flow rate directly affect the temperature and acidity of the fermentation process. A fast flow rate may cause rapid reproduction of microorganisms in the early stage of fermentation, but too fast gas exchange may be detrimental to the stable metabolism of microorganisms and increase the risk of infection by bacteria. A slow flow rate can provide a more stable gas environment, which is conducive to the stable growth and metabolism of microorganisms, but the fermentation speed is slower and may require a longer fermentation time. Therefore, controlling the oxygen flow rate is crucial for the saccharification and fermentation process of liquor.

[0003] At present, the microbial fermentation gas supply components on the market are directly connected to the gas pipeline of the air pump, and cannot freely adjust the oxygen flow rate in the pipeline according to the oxygen supply needs, which will cause the oxygen flow rate in the pipeline to be too fast or too slow, and will directly affect the quality of microbial fermentation. Utility Model Content

[0004] The purpose of the utility model is to provide a gas transmission component for microbial fermentation of liquor saccharification, which can automatically monitor and autonomously regulate the flow rate, accurately control the oxygen flow rate, and effectively avoid the influence of excessively fast or slow oxygen flow rate on the fermentation quality of microorganisms.

[0005] The technical solutions adopted by this utility model are as follows:

[0006] A gas supply component for microbial fermentation of liquor saccharification comprises an air pump, an air inlet end of the air pump being connected to an oxygen inlet pipe for supplying oxygen, an air outlet end of the air pump being connected to a first oxygen supply pipe, one end of the first oxygen supply pipe being connected to a control box, an end of the control box remote from the first oxygen supply pipe being connected to a second oxygen supply pipe, one end of the second oxygen supply pipe being connected to a speed measuring box, an end of the speed measuring box remote from the second oxygen supply pipe being connected to a third oxygen supply pipe docked with a fermentation tank, a controller being provided on the front of the control box, and monitoring and control components being provided in the control box and the speed measuring box.

[0007] The monitoring and control component includes a push block slidably arranged in the control box and used in conjunction with the first oxygen supply tube and the second oxygen supply tube. The top of the control box is fixedly connected to an electric push rod, the piston rod of the electric push rod passes through the control box and is fixed on the push block, and a rotating shaft is installed in the speed measuring box for longitudinal rotation. Multiple groups of blades are evenly fixed on the surface of the rotating shaft and the blades are located in the speed measuring box. One end of the rotating shaft is provided with an angle encoder, and the outer shell of the angle encoder is fixed with a fixing rod and one end of the fixing rod is fixed to the speed measuring box.

[0008] The ends of the first oxygen supply pipe and the second oxygen supply pipe that are close to each other are located on the same transverse axis, and the first oxygen supply pipe and the second oxygen supply pipe are located at the tops of both sides of the speed measuring box.

[0009] The end of the third oxygen supply pipe close to the speed measuring box is in a telescopic tube structure.

[0010] The number of the fixing rods is at least two groups.

[0011] The height of the push block is greater than the diameters of the first oxygen supply tube and the second oxygen supply tube.

[0012] The technical effects achieved by this utility model are:

[0013] The utility model discloses a gas transmission component for microbial fermentation of liquor saccharification. By setting a monitoring and regulating component, under the impact of oxygen, the blades and the rotating shaft will rotate accordingly, and with the cooperation of the angle encoder, the rotation speed of the blades can be monitored in real time, so as to monitor the oxygen flow rate in real time; using an electric push rod as a driving source, the position of the push block can be controlled, so that the pipe openings of the first oxygen supply pipe and the second oxygen supply pipe can be partially covered as needed, so as to quickly adjust the oxygen flow rate and flow rate. The oxygen flow rate can be accurately controlled by automatically monitoring and independently regulating the flow rate, which can effectively prevent the oxygen flow rate from being too fast or too slow to affect the fermentation quality of the microorganisms.

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0020] like Figure 1 - Figure 3 As shown, a microbial fermentation gas supply component for liquor saccharification includes an air pump 1, the air inlet end of the air pump 1 is connected to an oxygen inlet pipe 2 for supplying oxygen, the air outlet end of the air pump 1 is connected to a first oxygen supply pipe 3, one end of the first oxygen supply pipe 3 is connected to a control box 4, the end of the control box 4 away from the first oxygen supply pipe 3 is connected to a second oxygen supply pipe 8, one end of the second oxygen supply pipe 8 is connected to a speed measuring box 9, and the end of the speed measuring box 9 away from the second oxygen supply pipe 8 is connected to a third oxygen supply pipe 14 connected to the fermentation tank, a controller 6 is provided on the front of the control box 4, and monitoring and control components are provided in the control box 4 and the speed measuring box 9.

[0021] Specifically, after oxygen is input into the air pump 1 through the oxygen inlet pipe 2 and stored, it is circulated into the fermenter through the first oxygen supply pipe 3, the second oxygen supply pipe 8, the third oxygen supply pipe 14 and the monitoring and control component. The controller 6 is used to control the monitoring and control component.

[0022] like Figure 2 and Figure 3 As shown, the monitoring and control component includes a push block 7 that is slidably arranged in the control box 4 and is used in conjunction with the first oxygen supply tube 3 and the second oxygen supply tube 8. The top of the control box 4 is fixedly connected to an electric push rod 5. The piston rod of the electric push rod 5 passes through the control box 4 and is fixed on the push block 7. A rotating shaft 10 is installed in the speed measuring box 9 for longitudinal rotation. A plurality of groups of blades 11 are evenly fixed on the surface of the rotating shaft 10, and the blades 11 are located in the speed measuring box 9. An angle encoder 12 is provided at one end of the rotating shaft 10. A fixing rod 13 is fixed to the outer shell of the angle encoder 12, and one end of the fixing rod 13 is fixed to the speed measuring box 9.

[0023] Among them, the speed measuring box 9 is used to connect the second oxygen supply pipe 8 and the third oxygen supply pipe 14. The oxygen flowing from the second oxygen supply pipe 8 to the third oxygen supply pipe 14 passes through the speed measuring box 9, and then drives the rotating shaft 10 to rotate through the blade 11. Subsequently, the speed of the blade 11 is monitored by the angle encoder 12 to infer the flow rate of oxygen, which can effectively monitor the oxygen flow rate in real time. The control box 4 is used to connect the first oxygen supply pipe 3 and the second oxygen supply pipe 8. The controller 6 drives the electric push rod 5 to freely change the position of the push block 7, so that the pipe openings of the first oxygen supply pipe 3 and the second oxygen supply pipe 8 on the inner wall of the control box 4 can be partially covered to quickly adjust the oxygen flow rate and flow.

[0024] like Figure 1 and Figure 2 As shown, the ends of the first oxygen supply pipe 3 and the second oxygen supply pipe 8 that are close to each other are on the same transverse axis, and the first oxygen supply pipe 3 and the second oxygen supply pipe 8 are located at the top of both sides of the speed measuring box 9.

[0025] Specifically, the design of being on the same transverse axis enables the push block 7 to accurately reduce or close the pipe openings of the first oxygen supply pipe 3 and the second oxygen supply pipe 8. The limitation of the positions of the first oxygen supply pipe 3 and the second oxygen supply pipe 8 enables the oxygen flowing in the speed measuring box 9 to drive the blade 11 to rotate, so that the angle encoder 12 can monitor the oxygen flow rate in real time.

[0026] like Figure 3 As shown, the end of the third oxygen supply pipe 14 close to the speed measuring box 9 is a telescopic tube structure.

[0027] Specifically, the design of the telescopic tube structure facilitates increasing the length of the third oxygen supply tube 14 , and the third oxygen supply tube 14 is made of a flexible pipe material, which facilitates the installation of its top end on the top of the fermentation tank.

[0028] like Figure 3 As shown, the number of the fixing rods 13 is at least two groups.

[0029] The design of multiple sets of fixing rods 13 is used to stabilize the angle encoder 12 .

[0030] like Figure 2 As shown, the height of the push block 7 is greater than the diameters of the first oxygen supply pipe 3 and the second oxygen supply pipe 8 .

[0031] Specifically, different diameter values ​​are designed to better control the oxygen flow rate.

[0032] The working principle of the present invention is as follows: the user turns on the air pump 1 through the controller 6, and the air pump 1 delivers oxygen to the first oxygen supply pipe 3 through the oxygen inlet pipe 2, and delivers it to the fermenter through the control box 4, the second oxygen supply pipe 8, the speed measuring box 9, and the third oxygen supply pipe 14; and when the oxygen enters the speed measuring box 9, it will impact the blades 11, thereby driving the rotating shaft 10 to rotate. At this time, the angle encoder 12 monitors the rotation speed of the blades 11 and the rotating shaft 10 in real time, so that the oxygen flow rate can be monitored in real time. If the blade 11 rotates too fast, the electric push rod 5 is driven to open by the controller 6, pushing the push block 7 to move, so that the pipe openings of the first oxygen supply pipe 3 and the second oxygen supply pipe 8 on the inner wall of the control box 4 can be partially covered, so as to quickly adjust the oxygen flow rate and flow, and effectively avoid the oxygen flow rate being too fast or too slow and affecting the fermentation quality of the microorganisms.

[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
