Description

Technical Field

[0001] The utility model belongs to the technical field of biological fermentation inoculation, and particularly relates to a biological fermentation inoculation device. Background Art

[0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. The level of microbial fermentation production mainly depends on the genetic characteristics of the strain itself and the culture conditions. Microbial fermentation generally requires the use of specific equipment to cultivate microorganisms to obtain corresponding products. However, some existing microbial fermentation inoculation devices often have certain deficiencies when used and need to be improved.

[0003] In the Chinese patent with publication number CN214881467U, a microbial fermentation inoculation device is mentioned, which not only makes the microorganisms evenly distributed in the culture solution, but also ensures the oxygen required by the microorganisms during the growth process, improves the utilization rate of the culture solution, promotes the growth and reproduction of microorganisms, and improves practicality; it includes a base plate, a support box, an air bin, an air inlet pipe, a sterilization device, a fermentation bin, an exhaust main pipe, a first bevel gear, a second bevel gear, a drive shaft, a motor, multiple groups of exhaust branch pipes, multiple groups of exhaust nozzles, stirring blades, an air outlet pipe and a discharge pipe, the support box is fixedly mounted on the upper end of the base plate, a chamber is provided inside the support box, the air bin is fixedly mounted on the lower end of the support box chamber, an air cavity is provided inside the air bin, the output end of the air inlet pipe is connected to the air cavity of the air bin, an air pump is provided on the air inlet pipe, and the input end of the air inlet pipe is connected to the output end of the sterilization device.

[0004] However, although the above technical solution can achieve the purpose of fermenting and culturing microorganisms when in use, it uses an inoculation tube to place the microorganisms into the culture solution in the working chamber inside the fermentation bin. Since the fermentation bin contains structures such as stirring blades and exhaust nozzles, the microorganisms may adhere to these structures when entering the fermentation bin, resulting in a decrease in the number of microorganisms, making it difficult to mix them with the corresponding amount of nutrient solution. At the same time, the microorganisms adhered to these structures will gradually dry up and crack, thereby increasing the difficulty of subsequent cleaning work for the staff, and have certain limitations when in use.

Through the setting of the drive motor 6, it provides a certain driving force for the rotation of the cam 7. Through the combination of the cam 7 and the drive motor 6, the push rod 8 can be hit upward and then fall downward by its own gravity. Through the setting of the blocking rod, the push rod 8 is prevented from falling completely downward by gravity. Through the setting of the connecting rod 26, when the push rod 8 moves upward, it can drive the support plate 4 to move upward through the connecting rod 26.

[0030] Example 2:

[0031] See also Figure 1 、 Figure 3 and Figure 4 As shown,

[0032] The top of one side of the fermentation bin 1 is fixedly connected to a filter chamber 13, and the bottom ends of both sides of the inner wall of the filter chamber 13 are fixedly connected to a positioning seat 14, and a filter screen 15 is inserted into the interior of the positioning seat 14. The top of the filter chamber 13 is connected to a cover plate 16, and the interiors of both sides of the top of the filter chamber 13 are fixedly connected to a first magnet 17, and the interiors of both sides of the bottom of the cover plate 16 are fixedly connected to a second magnet, and the first magnet 17 and the second magnet attract each other.

[0033] The working principle of the present invention is as follows: the staff unscrews the sealing cover in advance, and then the feed port 2 is opened, and at the same time a certain amount of nutrient solution is put into the culture dish 5. At this time, the staff injects the microorganisms into the culture dish 5 inside the fermentation bin 1 through the inoculation tube. After injecting a certain amount, the staff connects the suction pipe 19 at the air inlet end of the air pump 18 and the container filled with sterilized gas, so that the sterilized gas enters the air delivery pipe 20 at the air outlet end of the air pump 18 through the suction pipe 19, and then the gas passes through the filter cavity 13 and the filter mesh 15 inside it, and finally enters the exhaust pipe 21, so that the exhaust pipe 21 transports the sterilized gas to the inside of the fermentation bin 1 and blows it directly to the position above the culture dish 5, so that it provides a certain amount of oxygen for the growth of microorganisms. At the same time, the staff controls the drive motor 6 to start, and the output end of the drive motor 6 drives the cam 7 to rotate. The rotation of the cam 7 pushes the push rod 8 upward. In this process, the push rod 8 drives the support plate 4 to move upward through the connecting rod 26, thereby causing the extrusion rod 9 to move upward, squeezing The rod 9 moves upward, driving the extrusion block at its top to squeeze the compression spring 12, thereby causing the support plate 4 to move upward. When the cam 7 rotates to the opposite side, the top rod 8 falls downward by gravity, and the compression spring 12 pushes the extrusion rod 9 downward through the reverse force, thereby restoring the support plate 4. This cycle repeats, causing the microorganisms and nutrient solution inside the culture dish 5 to swing up and down, thereby allowing the microorganisms and nutrient solution inside the culture dish 5 to be fully mixed, avoiding uneven dispersion of microorganisms. After the microorganisms have grown for a certain period of time, the staff will open the control valve to allow the microorganisms to fall downward through the discharge pipe 23. The staff can use a collection device to catch them at the bottom of the discharge pipe 23. After the filter screen 15 inside the filter chamber 13 has been used for a certain period of time, the staff will lift the cover plate 16 upward, and then the first magnet 17 and the second magnet are separated, thereby separating the cover plate 16 from the filter chamber 13. The staff will then pull the filter screen 15 out of the positioning seat 14 and then clean the filter screen 15.
