Description

Technical Field

[0001] The present invention relates to the technical field of microbial inoculum fermentation culture, and specifically to a fermentation culture device for nematode-resistant microbial inoculum. Background Art

[0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products required by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation mainly depends on the genetic characteristics of the strains themselves and the culture conditions, and is widely used in industries such as the pharmaceutical industry, food industry, energy industry, chemical industry, and agriculture. Nematode-resistant microbial inoculum is a biological agent that uses beneficial microorganisms to control plant parasitic nematodes such as root-knot nematodes.

[0003] A fermentation device refers to a device used for microbial fermentation that can withstand steam sterilization.

[0004] When the existing fermentation devices carry out microbial fermentation, it is necessary to batch-feed carbon sources according to different situations. Currently, when feeding carbon sources, it is carried out by manually opening the device multiple times, which increases the feeding difficulty. Moreover, opening the device multiple times will damage the airtightness of the fermentation system, causing gas leakage, thereby affecting the fermentation rate and the quality of fermentation products. During the fermentation process, it is necessary to timely introduce oxygen into the device. Currently, oxygen is directly injected into the device, and it is impossible to inject oxygen during the stirring process to enable better contact between the microbial fermentation liquid and oxygen, resulting in the nematode-resistant microorganisms at the bottom of the nematode-resistant microbial inoculum being unable to contact oxygen. At the same time, when the existing device stirs, it is carried out by a stirring rod with stirring blades. Continuous stirring with a relatively large stirring rod will cause the contact area between the microorganisms and the stirring blades to be too large, resulting in mutual collisions, thereby damaging the integrity of microbial cells.

[0005] Therefore, a fermentation culture device for nematode-resistant microbial inoculum is proposed. Summary of the Invention

At the same time, the air passage pipe directly leads oxygen into the nematode-proof microbial agent and nutrients, avoiding the situation of introducing oxygen into the existing reaction container, thereby reducing the occurrence that the nematode-proof microbial agent at the bottom of the nematode-proof microbial agent cannot contact oxygen, and avoiding the attachment of the nematode-proof microbial agent when the rotating block contacts the nematode-proof microbial agent.

The second rotating column 30 extends to the outside of the second cylinder 19.

[0046] An oxygen increasing assembly is provided on the second cylinder 19. The oxygen increasing assembly includes a plurality of third cylinders 32 fixedly communicated with the outside of the second cylinder 19. Not less than two air outlet pipes 33 are fixedly communicated with the outside of the plurality of third cylinders 32. The two air outlet pipes 33 are symmetrically arranged with the center of the third cylinder 32 as a reference. The upper surface of the bottom of the fermentation housing 1 is fixedly connected with a suction pump 34. The suction pump 34 is externally connected with an oxygen cylinder. The air outlet end of the suction pump 34 is fixedly communicated with the bottom of the rotating cylinder 14.

[0047] The working principle of the above implementation is as follows:

[0048] The initialization steps are as follows:

[0049] The experimenter opens the cover plate on the first dosing pipe 2 and doses the nematode-resistant microbial agent into the inner cavity of the fermentation housing 1 through the inner cavity of the first dosing pipe 2. After the experimenter finishes dosing the nematode-resistant microbial agent, the cover plate on the first dosing pipe 2 is closed.

[0050] The working operation steps are as follows:

[0051] The working steps of the intermittent dosing assembly are as follows:

[0052] After the first motor 9 is powered on and starts, the output shaft end of the first motor 9 drives the first rotating column 10 to start rotating. The first rotating column 10 drives the residual disc 11 and the convex block 12 to rotate with the center of the first rotating column 10 as the reference. When the arc surface of the residual disc 11 passes through the arc notch of the arc-shaped gear 13, since the arc notch of the arc-shaped gear 13 and the outer arc surface of the residual disc 11 are mutually adapted, the rotation of the residual disc 11 will not drive the arc-shaped gear 13 to rotate. When the first rotating column 10 drives the convex block 12 to rotate to the arc-shaped gear 13, because the convex block 12 is located at the eccentric position of the first rotating column 10, when the convex block 12 approaches the arc-shaped gear 13, it will gradually enter the straight groove and mesh with each other. Therefore, the rotation of the convex block 12 drives the arc-shaped gear 13 to rotate with the connection point of the rotating housing 5 as the axis. At this time, the convex block 12 continues to rotate, so that the next straight groove of the arc-shaped gear 13 moves to the position of the previous straight groove. At the same time, the convex block 12 continues to rotate and slides out of the straight groove, so that the arc-shaped gear 13 rotates intermittently. At this time, the arc-shaped gear 13 drives the rotating housing 5 to rotate synchronously by sixty degrees. When the arc-shaped gear 13 rotates to drive the top nozzle of the discharge pipe 6 and the connecting pipe 8, because a photoelectric sensor and a solenoid valve are arranged on the outer side of the discharge pipe 6, and the photoelectric sensor can control the opening and closing of the solenoid valve, it plays a role that when the discharge pipe 6 rotates above the connecting pipe 8, the sucrose powder in the rotating housing 5 can be discharged from the discharge pipe 6 into the connecting pipe 8. Furthermore, the sucrose powder discharged from the rotating housing 5 enters the connecting pipe 8 through the discharge pipe 6. When the sucrose powder enters the connecting pipe 8, due to the influence of its own gravity, the sucrose powder enters the inner cavity of the fermentation housing 1 through the connecting pipe 8 and scatters in the nematode-resistant microbial agent. At the same time, when the sucrose powder dosing is completed and the staff observes that the appropriate concentration is reached after dosing, at this time, the electric telescopic rod 35 is powered on and its telescopic shaft end pushes the two shutter plates 36 towards the direction close to the top of the connecting pipe 8. When the two shutter plates 36 completely cover the top of the connecting pipe 8, at this time, the electric telescopic rod 35 stops extending. Therefore, the photoelectric sensor of the discharge pipe 6 cannot recognize that the discharge pipe 6 coincides with the connecting pipe 8, so the discharge pipe 6 stops feeding.

[0053] The setting of the intermittent component can supplement the carbon source in the nematode-proof microbial inoculum, achieve the purpose of quantitative dosing, avoid the problem of dosing with the lid open, and achieve the purpose of automatic batch dosing. It enables the staff to have enough time to observe the concentration after dosing. At the same time, the intermittent dosing of the carbon source avoids the waste caused by a one-time input and prevents the growth of the nematode-proof microbial inoculum from being inhibited due to excessive carbon source.

[0054] The working steps of the stirring component are as follows:

[0055] As described above, before the rotation column 1 starts to rotate, the rotating cylinder 14 remains stationary at this time. The experimenter turns on the second motor 16. After the second motor 16 is powered on, the output shaft end drives the rotating shaft 17 to start rotating in the inner cavity of the rotating cylinder 14, and the rotating shaft 17 rotates in the same direction as the rotating cylinder 14. The rotation of the rotating shaft 17 drives the first bevel gear 18 to rotate synchronously. Therefore, the first bevel gear 18 drives the second bevel gear 21 meshing with it to start rotating. The second bevel gear 21 drives the threaded rod 22 to rotate synchronously on the fixed column 20. The rotation of the threaded rod 22 drives the sliding block 24 to slide away from the second bevel gear 21 on the limiting rod 23. The sliding of the sliding block 24 drives the connecting rod 25 to move synchronously. The connecting rod 25 pushes the connecting rod 26 to move synchronously. The connecting rod 26 pushes the connecting rod 27 to move away from the threaded rod 22. The connecting rod 27 drives the connecting rod 29 to swing around the center of the rotation column 2 30 as the axis. As a result, the connecting rod 27 undergoes displacement. The function of the connecting rod 26 is to prevent the connecting rod 27 from getting stuck during displacement. At the same time, the connecting rod 29 drives the rotation column 2 30 to start rotating around its own center as the axis at the bottom of the fixing plate 28. Therefore, the rotation column 2 30 drives the rotating block 31 to start rotating by 90 degrees. Thus, multiple rotating blocks 31 rotate by 90 degrees synchronously to form a closure, thereby forming a complete plate shape. At the same time, when the staff drives the second motor 16 to reverse, the above opposite steps can be repeated at this time. Thus, the rotating block 31 can achieve reciprocating swinging, and at the same time, multiple rotating blocks 31 can also achieve synchronous rotation by 90 degrees to form a closure. When the rotation column 1 starts to rotate, at this time, the rotation column 1 drives the rotating cylinder 14 to rotate synchronously through the synchronous belt 15. Therefore, the rotating cylinder 14 drives the four cylinders 19 to rotate around the center of the rotating cylinder 14. Thus, the four cylinders 19 and the rotating block 31 that can achieve reciprocating swinging together play a role in stirring.

[0056] The setting of the stirring component enables the multiple rotating blocks 31 to swing reciprocally. Thus, the swinging of the multiple rotating blocks 31 creates turbulence in the nematode-proof microbial agent, thereby improving the fluidity of the nematode-proof microbial agent, further increasing the sufficient contact between the nematode-proof microbial agent and nutrients. At the same time, when the multiple rotating blocks 31 rotate by 90 degrees to form a closed state, a complete board is formed, and the contact area with the nematode-proof microbial agent increases, making the mixing better and more uniform. When the multiple rotating blocks 31 are not closed, there are gaps between the rotating blocks 31, reducing the contact area and effectively minimizing the damage to the nematode-proof microorganism during the stirring process.

[0057] The working steps of the oxygenation component are as follows:

[0058] The experimenter turns on the switch of the suction pump 34, so that the suction pump 34 is powered on and starts to work. The suction pump 34 sucks the oxygen in the external oxygen cylinder into the inner cavity of the rotary drum 14. Since oxygen is a gas with fluidity, the oxygen enters the inner cavity of the second cylinder 19 through the rotary drum 14, and then enters the inner cavity of the third cylinder 32 through the second cylinder 19. Finally, the oxygen enters the inner cavity of the fermentation shell 1 through the air outlet pipe 33 and comes into contact with the nematode-proof microbial agent. At the same time, the air outlet pipe 33 blows the oxygen to the side of the rotating block 31, and after the fermentation of the nematode-proof microorganism is completed.

[0059] The setting of the oxygenation component can provide sufficient oxygen supply for the nematode-proof microbial agent during the stirring process. At the same time, the air outlet pipe 33 directly passes oxygen into the nematode-proof microbial agent and nutrients, avoiding the situation of passing oxygen into the reaction container used currently, thereby reducing the occurrence that the nematode-proof microorganisms at the bottom of the nematode-proof microbial agent cannot contact oxygen, and avoiding the attachment of nematode-proof microorganisms on the rotating block 31 when it contacts the nematode-proof microbial agent.
