Description

Technical Field

[0001] The invention relates to the technical field of bacterial liquid culture preparation equipment, in particular to a Flammulina velutipes bacterial liquid culture reactor. Background Art

[0002] Reactors are broadly understood as containers for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process can be achieved. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, medicine, and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation, such as reactors, reaction pots, decomposition pots, and polymerization kettles. The materials are generally carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials. In the manufacturing industry of biofertilizers, manufacturers transform traditional reactors for the cultivation of bacterial liquids.

[0003] Traditional culture tanks simply mix the culture solution and the strains during the production and cultivation process, which cannot ensure that the strains and the culture solution are fully and evenly mixed, resulting in uneven quality of liquid culture of Flammulina velutipes, affecting the quality of strain production and cultivation. At the same time, gas needs to be introduced during the cultivation process, which can easily cause unsterilized air to be injected into the culture tank, leading to hidden dangers such as deterioration of the strains in the culture tank. The nutrient solution cannot be fully mixed. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A Flammulina velutipes culture reactor, comprising a tank body, the tank body is used to provide a place for culturing Flammulina velutipes culture, and a support fixedly installed on the outside of the tank body, and a motor is fixedly connected to the top of the tank body;

[0005] A filtering mechanism, wherein the filtering mechanism is fixedly installed in the middle of the bottom of the tank;

[0006] A stirring mechanism, the stirring mechanism is fixedly connected to the output end of the motor, and the stirring mechanism is located inside the tank;

[0007] In which, the stirring mechanism includes a rotating component, the rotating component is fixedly connected to the motor, the outer side of the rotating component is fixedly connected to a circular tube, the outer side of the circular tube is provided with square holes, and the square holes are evenly distributed with the circular tube as the center, the circular tube is rotatably connected to an end of the circular tube away from the rotating component, and one end of the fixed ring is fixedly connected to a rotating plate, and the circular tube is tilted. During operation, the motor is connected to an external power supply, and the motor drives the rotating shaft to rotate, so that the rotating shaft drives the circular tube to rotate, so that the culture liquid inside the tank body flows, and then with the flow of the culture liquid, the rotating plate rotates around the fixed ring, and then the culture liquid and the bacterial strain in the tank body are stirred in multiple directions with multiple degrees of freedom through the rotation of the circular tube and the rotating plate, so that the bacterial strain and the culture liquid are mixed evenly, thereby ensuring the quality of bacterial strain culture production, there are two fixed rings, and the two fixed rings are symmetrically arranged with the rotating plate as the center, and the fixed ring is fixedly connected to a supporting rod at one end close to the rotating plate, and the supporting rod and the rotating plate are alternately arranged On the fixed ring, one end of the support rod close to the circular tube is fixedly connected with a return spring, and the outer side of the support rod is slidably connected with a baffle, and the rotating shaft drives the circular tube to rotate, so that the rotating plate drives the support rod to rotate, and under the elastic force of the return spring, the baffle is close to the circular tube, and when the baffle is away from the square hole, sterile air enters the rotating shaft through the filtering mechanism, so that the sterile air enters the interior of the tank body through the square hole, and then mixes with the bacteria and culture solution inside the tank body, and by stirring and ventilating, the sterile air injected into the tank body is dispersed to each position of the culture solution, so that the bacteria in the tank body and the culture solution in the tank body are fully mixed, and the quality of the culture production of the bacteria is further improved. As the support rod rotates, the baffle overlaps with the square hole at intervals, and an intermittent ventilation method is adopted to prevent continuous ventilation from causing the water in the culture solution to evaporate faster, resulting in the concentration of the culture solution, and affecting the normal growth environment of the bacteria solution. The baffle is fixedly connected to one end of the return spring away from the support rod, and the baffle is adapted to the square hole.

[0008] Preferably, a defoaming net is fixedly connected to the outer wall of the rotating component, and there are multiple defoaming nets, which are evenly distributed around the rotating component. A defoaming needle is fixedly connected to the outer side of the defoaming net. During the stirring and ventilation process, a large amount of foam may be generated in the bacterial liquid. At this time, the rotating shaft drives the defoaming net and the defoaming needle to cooperate with each other to defoam the foam on the upper surface of the culture liquid in the tank body, so as to prevent the foam from affecting the oxygen transfer efficiency and avoid the culture liquid from overflowing. The defoaming net is located above the circular tube.

[0009] Preferably, the rotating assembly includes a rotating shaft, which is fixedly connected to the output end of the motor, and a through hole is opened at the end of the rotating shaft away from the motor, and a positioning plate is fixedly connected to the inner wall of the through hole, and the positioning plate is set as an L-shaped ring block, and a limiting block is fixedly connected to the inner wall of the through hole, and the limiting block is a ring block with a middle protrusion. A ball is set on the inner wall of the through hole. During operation, sterile air enters the interior of the through hole. At this time, the ball moves upward under the action of the gas force, and the compression spring is stretched by the force, so that the ball moves away from the limiting block. At this time, the gas enters the interior of the circular tube through the limiting block. When the air pressure inside the through hole exceeds the limit amount, the oxygen solubility of the culture fluid inside the tank is saturated. At this time, the air pressure inside and outside the through hole is the same, so that the ball is reset under the elastic force of the compression spring. When the air is stopped, when the square hole is blocked, the gas cannot be discharged smoothly, and the air pressure inside the through hole will continue to rise, so that the ball drives the sphere to move upward, so that the spring plate is compressed, and the cylinder moves downward, and then the cylinder and the fixed plate cooperate with each other. At this time, the air pressure inside the through hole 512 remains unchanged, and the ball 514 is reset, and ventilation to the inside of the tank is stopped, and the equipment is repaired. The outer wall of the ball contacts the inner wall of the limit block, and the top of the limit block is fixedly connected with a compression spring, and the end of the compression spring away from the limit block is fixedly connected with the sphere, and the bottom of the sphere is provided with a round rod, and the sphere is fixedly connected to the ball through the round rod, and the round tube is fixedly connected with the fixed plate at the connection point of the through hole, and the inner wall of the through hole is slidably connected with a positioning component, and the positioning component is located above the fixed plate.

The air is filtered by setting a filter plate to prevent impurities in the air from entering the interior of the tank and preventing the culture solution from being contaminated. At the same time, the airflow drives the scraper to rotate, and the outer side of the filter plate is cleaned by the rotation of the scraper to prevent the filter plate from being blocked. The inner wall of the filter plate is fixedly connected with a partition, and the partition is set to an arc shape, and multiple partitions divide the interior of the filter plate into five parts. The partition is provided with filter holes near the middle of the filter plate. By setting the partition, the air entering the shell is diverted to improve the filtration efficiency. At the same time, the partition is used to extend the time that the air stays in the ultraviolet lamp space, effectively disinfecting the air. The partitions are evenly distributed with the filter plate as the center, and the inner wall of the filter plate is fixedly connected with an ultraviolet lamp. There are four partitions, and the four partitions are fixedly connected at one end away from the filter plate.

[0011] The present invention provides a Flammulina velutipes culture reactor, which has the following beneficial effects:

[0012] 1. The Flammulina velutipes culture reactor performs stirring operations on the culture solution and the strains in the tank body in multiple directions with multiple degrees of freedom through the rotation of the circular tube and the rotating plate, so that the strains and the culture solution are evenly mixed, thereby ensuring the quality of strain culture production.

[0013] 2. The Flammulina velutipes culture reactor allows the sterile air injected into the tank to be dispersed to every position of the culture solution by stirring and ventilating at the same time, so that the bacteria in the tank and the culture solution in the tank are fully mixed, and the culture production quality of the bacteria is further improved. As the support rod rotates, the baffle plate overlaps with the square hole at intervals, and an intermittent ventilation method is adopted to prevent continuous ventilation from accelerating the evaporation of water in the culture solution, resulting in the concentration of the culture solution and affecting the normal growth environment of the bacteria solution.

[0014] 3. The Flammulina velutipes liquid culture reactor has a sphere in contact with a spring plate, which is compressed to move the cylinder downward, and then the cylinder and the fixed plate cooperate with each other. At this time, the air pressure inside the through hole remains unchanged, and the sphere is reset to stop ventilation to the inside of the tank, so as to avoid the square hole being blocked and the gas cannot be discharged smoothly, which will cause excessive air pressure inside the through hole and easily cause danger.

[0015] Fourth, the Flammulina velutipes liquid culture reactor is provided with a filter plate to filter the air, thereby preventing impurities in the air from entering the tank body and preventing the culture liquid from being contaminated. At the same time, the airflow drives the scraper to rotate, and the outer side of the filter plate is cleaned by the rotation of the scraper to avoid clogging of the filter plate.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0028] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a Flammulina velutipes culture reactor, comprising a tank body 2, the tank body 2 is used to provide a place for culturing Flammulina velutipes culture, and a support 1 fixedly installed on the outside of the tank body 2, and a motor 3 is fixedly connected to the top of the tank body 2;

[0029] The filtering mechanism 4 is fixedly installed in the middle of the bottom of the tank body 2;

[0030] A stirring mechanism 5, which is fixedly connected to the output end of the motor 3 and is located inside the tank body 2;

[0031] The stirring mechanism 5 includes a rotating assembly 51, which is fixedly connected to the motor 3. A round tube 54 is fixedly connected to the outer side of the rotating assembly 51. Square holes 55 are opened on the outer side of the round tube 54. The square holes 55 are evenly distributed around the round tube 54. One end of the round tube 54 away from the rotating assembly 51 is rotatably connected to a fixing ring 510. One end of the fixing ring 510 is fixedly connected to a rotating plate 56. The round tube 54 is tilted. During operation, the motor 3 is connected to an external power supply, and the motor 3 drives the rotating shaft 511 to rotate, so that the rotating shaft 511 drives the round tube 54 to rotate, so that the tank body 2, and as the culture liquid flows, the rotating plate 56 rotates around the fixed ring 510, and then the culture liquid and the bacterial strain in the tank body 2 are stirred in multiple degrees of freedom and in different directions through the rotation of the circular tube 54 and the rotating plate 56, so that the bacterial strain and the culture liquid are evenly mixed to ensure the quality of bacterial strain culture production. There are two fixed rings 510, and the two fixed rings 510 are symmetrically arranged with the rotating plate 56 as the center. One end of the fixed ring 510 close to the rotating plate 56 is fixedly connected to the support rod 57, and the support rod 57 and the rotating plate 56 are alternately arranged on the fixed ring 510. On the fixed ring 510, one end of the support rod 57 close to the circular tube 54 is fixedly connected with a return spring 59, and the outer side of the support rod 57 is slidably connected with a baffle 58. The rotating shaft 511 drives the circular tube 54 to rotate, so that the rotating plate 56 drives the support rod 57 to rotate. Under the elastic force of the return spring 59, the baffle 58 is close to the circular tube 54. When the baffle 58 is away from the square hole 55, the sterile air enters the rotating shaft 511 through the filter mechanism 4, so that the sterile air enters the tank body 2 through the square hole 55, and then mixes with the bacteria and culture solution inside the tank body 2. Through stirring and ventilation, The sterile air injected into the tank body 2 is dispersed to each position of the culture liquid, so that the bacteria in the tank body 2 and the culture liquid in the tank body 2 can be fully mixed, and the culture production quality of the bacteria can be further improved. As the support rod 57 rotates, the baffle 58 overlaps with the square hole 55 intermittently, and intermittent ventilation is adopted to prevent continuous ventilation from accelerating the evaporation of water in the culture liquid, causing the culture liquid to concentrate and affecting the normal growth environment of the bacteria liquid. The baffle 58 is fixedly connected to the end of the return spring 59 away from the support rod 57, and the baffle 58 is adapted to the square hole 55.

[0032] A defoaming net 52 is fixedly connected to the outer wall of the rotating component 51. There are multiple defoaming nets 52, which are evenly distributed around the rotating component 51. A defoaming needle 53 is fixedly connected to the outer side of the defoaming net 52. During the stirring and ventilation process, a large amount of foam may be generated in the bacterial liquid. At this time, the rotating shaft 511 drives the defoaming net 52 and the defoaming needle 53 to cooperate with each other to defoam the foam on the upper surface of the culture liquid in the tank body 2 to prevent the foam from affecting the oxygen transfer efficiency and avoid overflow of the culture liquid. The defoaming net 52 is located above the circular tube 54.

[0033] The second embodiment is based on the first embodiment. Figures 6 to 8 As shown, the rotating assembly 51 includes a rotating shaft 511, which is fixedly connected to the output end of the motor 3. A through hole 512 is opened at one end of the rotating shaft 511 away from the motor 3. A positioning plate 519 is fixedly connected to the inner wall of the through hole 512. The positioning plate 519 is set as an L-shaped ring block. The inner wall of the through hole 512 is fixedly connected to a limiting block 513. The limiting block 513 is a ring block with a middle protrusion. A ball 514 is set on the inner wall of the through hole 512. During the working process, sterile air enters the through hole 5 12, at this time, the ball 514 moves upward under the action of the gas force, and the compression spring 515 is stretched, so that the ball 514 is away from the limit block 513. At this time, the gas enters the inside of the round tube 54 through the limit block 513. When the air pressure inside the through hole 512 exceeds the limit, the oxygen solubility of the culture solution inside the tank body 2 is saturated. At this time, the air pressure inside and outside the through hole 512 is the same, so that the ball 514 is reset under the elastic force of the compression spring 515, and the through hole 512 stops at this time. When the square hole 55 is blocked, the gas cannot be discharged smoothly, which will cause the air pressure inside the through hole 512 to rise continuously, so that the ball 514 drives the ball 516 to move upward, so that the spring plate 5182 is compressed, and the cylinder 5181 moves downward, and then the cylinder 5181 cooperates with the fixing plate 517. At this time, the air pressure inside the through hole 512 remains unchanged, the ball 514 is reset, and then the ventilation to the inside of the tank body 2 is stopped.

At the same time, the airflow drives the scraper 46 to rotate, and the outer side of the filter plate 45 is cleaned by the rotation of the scraper 46 to prevent the filter plate from being blocked. The inner wall of the filter plate 45 is fixedly connected with a partition 48, and the partition 48 is set to an arc shape, and multiple partitions 48 divide the interior of the filter plate 45 into five parts. The partition 48 is provided with a filter hole near the middle of the filter plate 45. By setting the partition 48, the air entering the interior of the shell 41 is diverted to improve the filtering efficiency. At the same time, the partition 48 prolongs the time that the air stays in the ultraviolet lamp space, effectively disinfecting the air. The partitions 48 are evenly distributed with the filter plate 45 as the center. The inner wall of the filter plate 45 is fixedly connected with an ultraviolet lamp 49. There are four partitions 48, and the four partitions 48 are fixedly connected at one end away from the filter plate 45.
