Description

Technical Field

[0001] This utility model relates to the field of biological fermentation inoculation, specifically a biological fermentation inoculation device. Background Technology

[0002] Microbial fermentation inoculation devices are auxiliary devices used for fermentation and have a wide range of applications in the field of fermentation technology. The existing method of using microbial fermentation inoculation devices is to directly inject microorganisms into the culture medium in the fermenter through the inoculation tube, and then the microorganisms will produce and multiply in the culture medium.

[0003] Existing microbial fermentation inoculation devices, such as the biological fermentation inoculation device disclosed in CN221854608U, use an air pump to deliver sterilized oxygen to the interior of the gas chamber through an air duct. At this point, a sterilization lamp can be turned on to further sterilize the oxygen inside the gas chamber. When oxygen is needed to enter the fermentation chamber, an electromagnetic gas shut-off valve is opened, allowing oxygen to be delivered through the main exhaust pipe and exhaust branch pipe. Normally, the electromagnetic gas shut-off valve can prevent the backflow of fermentation materials. However, the electromagnetic gas shut-off valve requires electricity for daily use, which necessitates a power connection. Since the electromagnetic gas shut-off valve is installed at the top of the main exhaust pipe, the rotation of the main exhaust pipe during use also rotates the electromagnetic gas shut-off valve, potentially causing the wires connected to the valve to become tangled and break. Furthermore, the exhaust branch pipe is located above the electromagnetic gas shut-off valve. While the electromagnetic gas shut-off valve can prevent the fermentation materials from flowing back into the main exhaust pipe, it cannot prevent them from flowing back into the exhaust branch pipe. Therefore, we propose a biological fermentation inoculation device. Utility Model Content

[0004] The purpose of this utility model is to provide a biological fermentation inoculation device, including a tank body. A top cover is fixed to the top of the tank body by fixing bolts. The top cover is rotatably connected to a rotating shaft through a sealed bearing. A stirring and gas-exhausting component is provided on the rotating shaft. The stirring and gas-exhausting component stirs the raw materials in the tank body and injects sterilized oxygen. A gas pipe is rotatably connected to the outer wall of the rotating shaft through a sealed bearing. A sealing ring is fixed on the inner wall of the gas pipe. The sealing ring is tightly and movably fitted to the rotating shaft. The inner cavity of the sealing ring is inverted conical. The gas outlet of a solenoid valve is connected to the top of the gas pipe.

[0005] Preferably, the agitation and gas outlet assembly includes multiple sets of agitator blades, all of which are fixedly installed on the outer wall of the rotating shaft. The multiple sets of agitator blades are fixedly connected to three sets of air passages. The top of the air passages is sealed, and the bottom of the air passages is open. The three sets of air passages are connected to multiple sets of ventilation pipes between themselves and the inner cavity of the rotating shaft. Each of the three sets of air passages is connected to multiple sets of oxygen outlet pipes, and the oxygen outlet pipes are all inclined.

[0006] Preferably, a motor is fixedly installed on the top cover, and the drive end of the motor is fixedly connected to a first bevel gear, the first bevel gear meshing with a second bevel gear, and the second bevel gear is fixedly installed on the outer wall of the rotating shaft.

[0007] Preferably, a stabilizer is fixedly installed on the outer wall of the trachea, the air inlet of the solenoid valve is connected to the oxygen pipe, a stabilizer is fixedly installed on the outer wall of the oxygen pipe, and both the stabilizer and the stabilizer are fixedly installed on the top cover.

[0008] Preferably, a feed pipe is installed through the upper end of the side wall of the tank, and a sealing cap is threadedly connected to the inlet of the feed pipe.

[0009] Preferably, an exhaust pipe is installed through the upper end of the side wall of the tank, and a valve is fitted on the exhaust pipe.

[0010] Preferably, an observation glass is provided in the middle of the tank, and four sets of support legs are fixedly installed at the bottom of the tank.

[0011] Preferably, the bottom of the tank is connected to a discharge pipe, and a valve is installed on the discharge pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When the rotating shaft of this invention rotates, the outer wall of the rotating shaft is rotatably connected to the air pipe through a sealed bearing. A sealing ring is fixed on the inner wall of the air pipe. The sealing ring is tightly and movably fitted to the rotating shaft. The inner cavity of the sealing ring is inverted conical. The air pipe can be fixed in place, so that the solenoid valve does not need to rotate. Furthermore, the sealing ring and the sealed bearing ensure good sealing between the rotating shaft and the air pipe.

[0013] When oxygen is injected, it enters the tank from the oxygen outlet pipe and the opening at the bottom of the air passage. During this process, the agitating air outlet component rotates continuously, and the position of the opening at the bottom of the oxygen outlet pipe and air passage changes constantly, injecting oxygen into different positions inside the tank. This allows the oxygen to be distributed more quickly and evenly in the inner cavity of the tank, ensuring the inoculation of bacteria in different positions inside the tank.

[0014] After the oxygen injection is completed, close the solenoid valve. Even if the fermentation material tends to flow back along the air passage at the moment the solenoid valve is closed, the bottom of the air passage is open and there are multiple sets of oxygen outlet pipes connected to the air passage. The oxygen outlet pipes are inclined, so that the air passage has multiple openings connected to the inner cavity of the tank. This disperses the backflow force, so that the backflow force cannot carry the fermentation material into the air passage. Attached Figure Description

[0019] The agitation and gas outlet assembly 4 includes multiple sets of stirring blades 401, all of which are fixedly installed on the outer wall of the rotating shaft 3. These multiple sets of stirring blades 401 are fixedly connected to three sets of air passages 402. The top of each air passage 402 is sealed, while the bottom is open. Each of the three sets of air passages 402 is connected to multiple sets of ventilation pipes 403 within the inner cavity of the rotating shaft 3. Each of the three sets of air passages 402 is connected to multiple sets of oxygen outlet pipes 404, all of which are inclined. The agitator 4 can stir the raw materials inside the tank 1, making the inoculum evenly distributed and more fully inoculated. When oxygen is injected, oxygen is injected into the tank 1 from the opening at the bottom of the oxygen outlet pipe 404 and the air passage 402. During the injection of oxygen, the position of the opening at the bottom of the oxygen outlet pipe 404 and the air passage 402 changes continuously, injecting oxygen into different positions inside the tank 1. This allows the oxygen to be distributed more quickly and evenly in the inner cavity of the tank 1, ensuring the inoculation of inoculum at different positions inside the tank 1.

[0020] The top cover 2 is fixedly equipped with a motor 8. The drive end of the motor 8 is fixedly connected to a bevel gear 9. The bevel gear 9 meshes with a bevel gear 10. The bevel gear 10 is fixedly installed on the outer wall of the rotating shaft 3. When in use, starting the motor 8 will drive the bevel gear 9 to rotate. The rotation of the bevel gear 9 will drive the bevel gear 10 to rotate. The rotation of the bevel gear 10 will drive the rotating shaft 3 to rotate. It should be noted that when the motor 8 is in use, it needs to be connected to a suitable external power supply with its dedicated controller and its operation is controlled by the controller.

[0021] A stabilizing frame 11 is fixedly installed on the outer wall of the air tube 5. The air inlet of the solenoid valve 7 is connected to the oxygen tube 12. A stabilizing seat 13 is fixedly installed on the outer wall of the oxygen tube 12. Both the stabilizing frame 11 and the stabilizing seat 13 are fixedly installed on the top cover 2. The solenoid valve 7 can open or close the air tube 5. The stabilizing frame 11 and the stabilizing seat 13 ensure the stability of the air tube 5 and the oxygen rod 12 installation structure. It should be noted that when using the solenoid valve 7, it needs to be connected to a suitable external power supply in conjunction with its dedicated controller, and its operation is controlled by its controller.

[0022] A feed pipe 14 is installed through the upper end of the side wall of the tank 1, and a sealing cap is threaded to the opening of the feed pipe 14. In use, the sealing cap is rotated off and the inoculum solution is added into the tank 1 through the feed pipe 14.

[0023] An exhaust pipe 15 is installed through the upper end of the side wall of the tank 1, and a valve is fitted on the exhaust pipe 15. If needed during use, the valve on the exhaust pipe 15 can be opened to discharge the gas inside the tank 1 through the exhaust pipe 15.

[0024] An observation glass 16 is provided in the middle of the tank body 1, and four sets of support legs 17 are fixedly installed at the bottom of the tank body 1. During use, the situation inside the tank body 1 can be observed through the observation glass 16, and the four sets of support legs 17 can provide strong support for the tank body 1.

[0025] The bottom of the tank 1 is connected to a discharge pipe 18, and a valve is installed on the discharge pipe 18. After fermentation in the tank 1 is completed, the valve on the discharge pipe 18 is opened, so that the bacteria in the tank 1 are discharged from the discharge pipe 18.

[0026] The working principle of this utility model is as follows: When in use, rotate to remove the sealing cap and add the inoculum liquid into the tank 1 through the feed pipe 14; start the motor 8 to drive the rotating shaft 3 to rotate, and the rotating shaft 3 will drive the stirring and agitating component 4 to rotate. The stirring and agitating component 4 can stir the raw materials in the tank 1, so that the inoculum is evenly distributed and can be inoculated more fully. When the rotating shaft 3 rotates, the outer wall of the rotating shaft 3 is rotatably connected to the air pipe 5 through the sealed bearing. The inner wall of the air pipe 5 is fixed with a sealing ring 5. The sealing ring 5 is tightly and movably fitted to the rotating shaft 3. The inner cavity of the sealing ring 5 is inverted conical. The air pipe can be fixed, so that the solenoid valve 7 does not need to rotate. And through the sealing ring 5 and the sealed bearing, the rotating shaft 3 and the air pipe 5 maintain good sealing. When oxygen is injected, the sterilized oxygen is injected into the oxygen pipe 12, and the solenoid valve 7 is opened, allowing oxygen to enter the inner cavity of the rotating shaft 3 through the solenoid valve 7 and the air pipe 5. The oxygen in the inner cavity of the rotating shaft 3 enters the air passage 402 through the vent pipe 403. The oxygen is injected into the tank 1 from the oxygen outlet pipe 404 and the opening at the bottom of the air passage 402. During this process, the agitating air outlet component 4 rotates continuously, and the positions of the openings at the bottom of the oxygen outlet pipe 404 and the air passage 402 change continuously, injecting oxygen into different positions inside the tank 1, so that the oxygen can... The bacteria are more quickly and evenly distributed in the inner cavity of the tank 1, ensuring inoculation of bacteria at different locations in the tank 1. After the oxygen injection is completed, the solenoid valve 7 is closed. Even if the fermentation raw material tends to flow back along the air passage 402 at the moment the solenoid valve 7 is closed, the bottom of the air passage 402 is open and multiple sets of oxygen outlet pipes 404 are connected to the air passage 402 and the oxygen outlet pipes 404 are inclined, so that the air passage 402 has multiple openings connected to the inner cavity of the tank 1. This backflow force is dispersed, so that this backflow force cannot carry the fermentation raw material into the air pipe 5.

It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
