Description

Technical Field

[0001] The invention relates to the technical field of microbial agent fermentation and cultivation, in particular to anti-nematode microbial agent fermentation and cultivation equipment. 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 production level of microbial fermentation mainly depends on the genetic characteristics and culture conditions of the strain itself. It is widely used in the pharmaceutical industry, food industry, energy industry, chemical industry, agriculture and other industries. Anti-nematode microbial agent is a biological agent that uses beneficial microorganisms to prevent and control plant parasitic nematodes such as root-knot nematodes.

[0003] Fermentation equipment refers to the equipment used for microbial fermentation that can withstand steam sterilization.

[0004] When the existing fermentation equipment is performing microbial fermentation, it is necessary to add carbon sources in batches according to different situations. The existing method of adding carbon sources is to open the equipment manually multiple times to add them, which increases the difficulty of adding them. The multiple openings of the equipment will destroy the air tightness of the fermentation system, causing gas loss, thereby affecting the fermentation rate and the quality of the fermentation product. In addition, during the fermentation process, oxygen needs to be introduced into the equipment in a timely manner. However, the existing method of injecting oxygen is to directly inject oxygen into the equipment. It is impossible to inject oxygen during the stirring process so that the microbial fermentation liquid can have better contact with oxygen, thereby causing the anti-nematode microbial bacteria at the bottom of the anti-nematode microbial inoculant to be unable to contact with oxygen. At the same time, the existing equipment is stirred by a stirring rod with stirring blades during stirring. Continuous stirring with a large stirring rod will cause the contact area between the microorganisms and the stirring blades to be too large, resulting in mutual collision, thereby destroying the integrity of the microbial cells.

[0005] Therefore, a fermentation and cultivation device for anti-nematode microbial agent is proposed. Summary of the invention

[0046] An oxygenation assembly is provided on the cylinder 19, and the oxygenation assembly includes a plurality of cylinders 32 fixedly connected to the outside of the cylinder 19, and the outsides of the plurality of cylinders 32 are fixedly connected to no less than two air outlet pipes 33, and the two air outlet pipes 33 are symmetrically arranged with the center of the cylinder 3 32 as a reference object. A suction pump 34 is fixedly connected to the upper surface of the bottom of the fermentation shell 1, and the suction pump 34 is externally connected to an oxygen cylinder, and the air outlet end of the suction pump 34 is fixedly connected to the bottom of the rotating drum 14.

[0047] The above implementation works as follows:

[0048] The initialization steps are as follows:

[0049] The experimenter opens the cover on the delivery pipe 2 and delivers the anti-nematode microbial agent into the inner cavity of the fermentation shell 1 through the inner cavity of the delivery pipe 2. After delivering the anti-nematode microbial agent, the experimenter closes the cover on the delivery pipe 2.

[0050] The working steps are as follows:

[0051] The intermittent delivery component works as follows:

[0052] After the first motor 9 is powered on, it starts, and the output shaft end of the first motor 9 drives the rotating column 10 to start rotating. The rotating column 10 drives the residual disc 11 and the protrusion 12 to rotate with the center of the rotating column 10 as a reference. When the arc surface of the residual disc 11 passes through the arc notch of the arc gear 13, the arc notch of the arc gear 13 and the outer arc surface of the residual disc 11 are adapted to each other, so the rotation of the residual disc 11 will not drive the arc gear 13 to rotate. When the rotating column 10 drives the protrusion 12 to rotate to the arc gear 13, because the protrusion 12 is located on the rotating column, the rotation of the residual disc 11 will not drive the arc gear 13 to rotate. At the eccentric part of 10, when the protrusion 12 approaches the arc gear 13, it will gradually enter the straight groove and mesh with each other. Therefore, the rotation of the protrusion 12 drives the arc gear 13 to rotate with the connection of the rotating shell 5 as the axis. At this time, the protrusion 12 continues to rotate, so that the arc gear 13 moves from the next straight groove to the previous straight groove position. At the same time, the protrusion 12 continues to rotate and slides out of the straight groove, so that the arc gear 13 rotates intermittently. At this time, the arc gear 13 drives the rotating shell 5 to rotate synchronously by 60 degrees. When the arc gear 13 rotates, it drives the discharge pipe 6 When the discharge pipe 6 is at the top of the connecting pipe 8, a photoelectric sensor and a solenoid valve are arranged on the outside of the discharge pipe 6, and the photoelectric sensor can control the opening and closing of the solenoid valve, so that when the discharge pipe 6 rotates to the top of the connecting pipe 8, the sucrose powder in the rotating shell 5 can be discharged from the discharge pipe 6 to the connecting pipe 8, and then the sucrose powder discharged from the rotating shell 5 enters the connecting pipe 8 through the discharge pipe 6. When the sucrose powder enters the connecting pipe 8, the sucrose powder is affected by its own gravity, so the sucrose powder passes through the connecting pipe 8. The pipe 8 enters into the inner cavity of the fermentation shell 1 and is scattered in the anti-nematode microbial agent. At the same time, the sucrose powder is added. After the staff observes that the appropriate concentration has been reached after the addition, the electric telescopic rod 35 is energized and its telescopic shaft end pushes the two baffles 36 to move toward the top of the connecting pipe 8. When the two baffles 36 completely cover the top of the connecting pipe 8, the electric telescopic rod 35 stops extending. Therefore, the photoelectric sensor of the discharge pipe 6 cannot recognize that the discharge pipe 6 overlaps with the connecting pipe 8, and the discharge pipe 6 stops unloading.

[0053] The setting of the intermittent component can play a role in supplementing the carbon source in the anti-nematode microbial agent, and at the same time achieve the purpose of quantitative delivery, avoid the problem of opening the cover for delivery, and realize the purpose of automatic delivery in batches, so that the staff has enough time to observe the concentration after delivery. At the same time, the intermittent delivery of carbon sources avoids the waste caused by one-time investment and avoids the inhibition of the growth of the anti-nematode microbial agent due to excessive carbon sources.

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

[0055] As described above, before the rotating column 10 starts to rotate, the rotating drum 14 remains stationary, and the experimenter turns on the second motor 16. After the second motor 16 is energized, its output shaft end drives the rotating shaft 17 to start rotating in the inner cavity of the rotating drum 14, and the rotating shaft 17 has the same rotation direction as the rotating drum 14. The rotation of the rotating shaft 17 drives the first bevel gear 18 to rotate synchronously, so the first bevel gear 18 drives the second bevel gear 21 meshing therewith to start rotating, and the second bevel gear 21 drives the threaded rod 22 to rotate synchronously on the fixed column 20, and the rotation of the threaded rod 22 drives the sliding block 24 to slide on the limiting rod 23 in the direction away from the second bevel gear 21, and the sliding of the sliding block 24 drives the connecting rod 1 25 to move synchronously, and the connecting rod 1 25 pushes the connecting rod 2 26 to move synchronously, and the connecting rod 2 26 pushes the connecting rod 3 27 to move in the direction away from the threaded rod 22, and the connecting rod 3 27 drives the connecting rod 4 29 to swing around the center of the rotating column 2 30 as the axis, so that the connecting rod 3 27 is displaced, and the function of the second connecting rod 26 is to prevent the third connecting rod 27 from getting stuck when it is displaced. At the same time, the fourth connecting rod 29 drives the second rotating column 30 to start rotating on the bottom of the fixed plate 28 with the center of the second rotating column 30 itself as the axis. Therefore, the second rotating column 30 drives the rotating block 31 to start rotating ninety degrees, so that multiple rotating blocks 31 rotate ninety degrees synchronously to form a closed state, thereby forming a complete board shape. At the same time, when the staff drives the second motor 16 to reverse, the above-mentioned reverse steps can be repeated at this time, so that the rotating block 31 can realize reciprocating swing, and at the same time, multiple rotating blocks 31 can also realize synchronous rotation of ninety degrees to form a closed state. When the rotating column 10 starts to rotate, the rotating column 10 drives the rotating drum 14 to rotate synchronously through the synchronous belt 15. Therefore, the rotating drum 14 drives the four cylinders 2 19 to rotate with the center of the rotating drum 14, so that the four cylinders 2 19 and the rotating block 31 that can realize reciprocating swinging play a stirring role together.

[0056] The arrangement of the stirring assembly enables the multiple rotating blocks 31 to swing back and forth, so that the swinging of the multiple rotating blocks 31 generates turbulence in the anti-nematode microbial agent, thereby improving the fluidity of the anti-nematode microbial agent, and further increasing the full contact between the anti-nematode microbial agent and nutrients. At the same time, when the multiple rotating blocks 31 rotate ninety degrees to form a closed plate to form a complete plate, the contact area between the anti-nematode microbial agent is increased, making the mixing more uniform. When the multiple rotating blocks 31 are not closed, there are gaps between the rotating blocks 31 to reduce the contact area, which effectively reduces the damage to the anti-nematode microbial agents during the stirring process.

[0057] The oxygenation component works 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 working. The suction pump 34 draws oxygen from the external oxygen cylinder into the inner cavity of the rotating drum 14. Since oxygen is a gas with fluidity, the oxygen enters the inner cavity of the second cylinder 19 through the rotating drum 14, and the oxygen then enters the inner cavity of the third cylinder 32 through the second cylinder 19. The oxygen finally enters the inner cavity of the fermentation shell 1 through the air outlet pipe 33 and contacts with the anti-nematode microbial agent. At the same time, the air outlet pipe 33 blows the oxygen to the side of the rotating block 31, and at the same time, after the anti-nematode microbial fermentation is completed.

[0059] The setting of the oxygenation component can provide sufficient oxygen supply for the anti-nematode microbial agent during the stirring process. At the same time, the air outlet pipe 33 directly passes oxygen into the anti-nematode microbial agent and nutrients, avoiding the current situation of passing oxygen into the interior of the reaction container, thereby reducing the occurrence of the anti-nematode microbial bacteria at the bottom of the anti-nematode microbial agent being unable to contact oxygen, and avoiding the anti-nematode microbial bacteria being attached to the rotating block 31 when it contacts the anti-nematode microbial agent.
