Description

Technical Field

[0001] The invention relates to the technical field of bio-based material cultivation, in particular to a bio-based material cultivation device which is convenient for ventilation. Background Art

[0002] In today's biotechnology field, the cultivation and research and development of bio-based materials have important strategic significance and broad application prospects. They are widely used in many industries such as medicine, environmental protection, and energy. During the cultivation process, bio-based materials need oxygen to participate in various biochemical reactions in cells to synthesize substances required for their own growth, provide energy, and maintain normal physiological functions.

[0003] In the prior art, the existing bio-based material culture equipment has a single ventilation direction, and cannot flexibly adjust the direction and angle of the jet according to the actual needs of bio-based material culture and changes in the properties of the culture medium. This results in uneven distribution of gas in the culture medium, and the bio-based materials cannot fully contact oxygen and other gases, making it difficult to ensure effective diffusion and mixing of the gas, further limiting the growth and development of the bio-based materials. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides a bio-based material cultivation device that is easy to ventilate, which solves the problem in the prior art that gases cannot be effectively diffused and mixed.

[0006] (II) Technical solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions: a bio-based material cultivation device that is easy to ventilate, including a base, and an electric heating platform fixed on the top of the base, and also including: a culture tank, the culture tank is fixedly connected to the top of the electric heating platform, the top of the culture tank is fixedly connected to an air compressor, the output end of the air compressor is fixedly connected to a ventilation device, the top of the base is fixedly connected to a drug adding cartridge and an exhaust valve, the top of the culture tank away from the exhaust valve is rotatably connected to a cover plate, and the bottom of the culture tank is fixedly connected to a drain pipe; a sterilant is added to the culture tank through the drug adding cartridge to provide a sterile environment for the cultivation of bio-based materials, and then the cover plate is opened to pour the culture solution of the bio-based material into the culture tank. The electric heating platform on the top of the base can heat the culture tank and adjust the culture solution to a suitable culture temperature.

[0008] The ventilation device comprises an air guide tube, a filter assembly is fixedly connected to the top of the air guide tube, a stirring assembly is fixedly connected to the outer wall of the air guide tube, a spiral air guide groove is opened in the inner wall of the ventilation device, and the compressed air is filtered by the filter assembly and then sent to the stirring assembly, and then sprayed into the culture tank through the stirring assembly. At this time, under the reverse thrust of the airflow, the stirring assembly can drive the air guide tube to rotate, so that the culture solution is evenly mixed, and the bio-based material is promoted to fully contact with the nutrients and gas, which is beneficial to the growth and metabolism of the bio-based material;

[0009] The filter assembly includes a protective shell, an aggregate shell is fixedly connected to the inner side of the protective shell, a conical filter plate is fixedly connected to the top of the aggregate shell, and a guide plate is fixedly connected to the inner side of the aggregate shell. The guide plates are tilted downward and arranged in a staggered manner in the aggregate shell. When the airflow passes through the guide plates, it will be continuously guided and blocked, and its flow rate and flow direction will change multiple times, thereby weakening the upward force of the airflow on impurities and effectively preventing the impurities from being recoiled. The air guide holes are opened behind the guide plates. When the impurities move in the direction of the air guide holes under the action of the airflow, the speed and direction of the airflow change, making it difficult for the impurities to obtain sufficient power to enter the air guide pipe through the air guide holes, thereby further improving the interception efficiency of the filter assembly for impurities;

Air enters the air guide ring from the air guide pipe and is then ejected through the injection component. At this time, the reverse thrust of the injection component drives the stirring assembly to rotate as a whole. As the spoiler fan and the stirring paddle rotate, they interact with the culture solution. By providing the torsion component, the spoiler fan can adaptively adjust the deflection angle as the viscosity of the culture solution changes during rotation.

[0011] Preferably, the outer side of the ventilation device is rotatably connected to the center of the culture tank, the exhaust valve is located on the side of the medicine adding cartridge away from the ventilation device, the outer side of the air duct is rotatably connected to the inner side of the culture tank, the top of the filter assembly is fixedly connected to the output end of the air compressor, and the bottom of the filter assembly is fixedly connected to the center of the top of the culture tank. When the pressure in the culture tank increases, the gas in the culture tank can be discharged through the exhaust valve, and when the culture tank is not in use, the fluid in the culture tank can be discharged through the drain pipe.

[0012] Preferably, the bottom of the protective shell is fixedly connected to the top of the culture tank, the inner side of the aggregate shell is rotatably connected to a ring-shaped scraper, the outer side of the protective shell is slidably connected to a cleaning plate, the inner side of the ring-shaped scraper is fixedly connected to the top of the air guide pipe, the top of the protective shell is fixedly connected to the output end of the air compressor, and air guide holes are opened in the wall of the aggregate shell. The ring-shaped scraper rotates with the air guide pipe to push impurities in the aggregate shell to the side close to the cleaning plate. When the cleaning plate is slid upward, the impurities inside the protective shell can be cleared out.

[0013] Preferably, the inner side of the air guide ring is fixedly connected to the outer side of the air guide pipe, the end of the movable rod away from the spoiler fan is rotatably connected to the outer side of the mounting frame, the torsion component and the jet component are arranged in a ring along the central axis of the air guide ring, and the spoiler fan forms a quadrilateral mechanism between the movable rod and the mounting frame. When the spoiler fan is deflected, the spoiler fan will drive the mounting frame to deflect synchronously with the jet component as the base point through the movable rod, so that the jet component will drive the agitator to deflect synchronously when it is deflected.

[0014] Preferably, the torsion component includes a fixed block, the outer side of the fixed block is rotatably connected to a rotating drum, the inner side of the rotating drum is fixedly connected to a torsion spring, the outer side of the fixed block is fixedly connected to a fixed plate, the inner side of the fixed plate is fixedly connected to an annular guide rod, the outer side of the annular guide rod is slidably connected to a limiting block, when the spoiler fan is deflected, the rotating drum is deflected relative to the fixed block, thereby causing the torsion spring to twist and accumulate force, and at the same time, the limiting block slides along the surface of the annular guide rod together with the rotating drum.

[0015] Preferably, the outer side of the fixed block is fixedly connected to the outer side of the air guide ring, the outer side of the rotating drum is fixedly connected to the outer side of the spoiler fan, the end of the torsion spring away from the rotating drum is fixedly connected to the outer side of the fixed block, and the inner side of the rotating drum is fixedly connected to the outer side of the limit block. When the limit block contacts the fixed plate, the fixed plate will prevent the rotating drum from continuing to rotate through the limit block, thereby ensuring that the inclination angles of the spoiler fan and the agitator are within a reasonable range.

[0016] Preferably, the jet component includes a jet pipe, the outer side of the jet pipe is rotatably connected to a connecting elbow, the inner wall of the jet pipe is fixedly connected to an annular block, the inner side of the annular block is fixedly connected to a compression spring, the end of the compression spring away from the annular block is fixedly connected to an air guide cylinder, and the outer side of the jet pipe is fixedly connected to an exhaust pipe. When the airflow enters the jet pipe through the connecting elbow, the airflow pushes the air guide cylinder to slide along the inner side of the annular block, forcing the compression spring to be compressed, thereby causing the jet hole to protrude from the annular block. At this time, the airflow can be ejected outward through the jet hole.

[0017] Preferably, the end of the connecting elbow away from the air guide cylinder is fixedly connected to the outer side of the air guide ring, the outer wall of the injection pipe is slidably connected to the inner wall of the air guide cylinder, the outer wall of the air guide cylinder is slidably connected to the inner side of the annular stopper, and injection holes are opened in the wall of the air guide cylinder.

When the airflow is ejected from the exhaust pipe, it can just spray on the surface of the agitator. When the airflow is sprayed on the surface of the agitator, it has a certain impact force, which can wash away some impurities, bio-based materials or metabolic products attached to the surface of the agitator.

[0019] (III) Beneficial effects

[0020] The present invention provides a bio-based material cultivation device that is easy to ventilate. It has the following beneficial effects:

[0021] (I) The equipment is equipped with a ventilation device. When the air enters the air duct through the filter assembly and flows along the spiral air duct groove, the air will generate a tangential force on the inner wall of the air duct according to the principle of fluid mechanics. This tangential force will form a torque, causing the air duct to tend to rotate around its axis, and then cooperate with the reverse thrust of the stirring assembly to drive the air duct to rotate, thereby improving the energy efficiency of the equipment.

[0022] (ii) The equipment is provided with a filter assembly. The conical filter plate can initially intercept larger impurities in the air. The impurities are trapped and roll down into the aggregate shell along the outer wall of the conical filter plate under the impact of the airflow. The guide plates are tilted downward and arranged in a staggered manner in the aggregate shell. When the airflow passes through the guide plates, it will be continuously guided and blocked, and its flow rate and flow direction will change many times, thereby weakening the upward force of the airflow on the impurities and effectively preventing the impurities from being recoiled.

[0023] (III) The device is provided with a filter assembly, and an air guide hole is opened behind the guide plate. When impurities move toward the air guide hole under the action of air flow, the speed and direction of the air flow change, making it difficult for impurities to obtain sufficient power to enter the air guide pipe through the air guide hole, thereby further improving the interception efficiency of the filter assembly for impurities. At the same time, the annular scraper rotates with the air guide pipe, which can push the impurities in the aggregate shell to the side close to the cleaning plate. When the cleaning plate slides upward, the impurities inside the protective shell can be cleared out.

[0024] (IV) The device is provided with a stirring assembly. Air enters the air guide ring from the air guide pipe and is then ejected through the jet component. At this time, the reverse thrust of the jet component drives the stirring assembly to rotate as a whole. The spoiler fan forms a quadrilateral mechanism between the movable rod and the mounting frame. When the spoiler fan deflects, the spoiler fan drives the mounting frame to deflect synchronously with the jet component as the base point through the movable rod, so that the jet component drives the stirring paddle to deflect synchronously when deflecting, thereby ensuring that the bio-based materials can obtain good culture conditions under different viscosity environments.

[0025] (V) The device is provided with an arc-shaped spoiler. When the arc-shaped spoiler rotates with the mounting frame, the arc-shaped spoiler can rotate relative to the mounting frame under the push of the culture fluid, thereby changing the original motion trajectory of the culture fluid, thereby forming complex eddies and turbulence in the culture fluid, increasing the degree of fluid turbulence, and facilitating full contact between bio-based materials and nutrients and gases.

[0026] (VI) The device is provided with a torsion assembly. When the spoiler fan is deflected, the drum is deflected relative to the fixed block, thereby causing the torsion spring to twist and store force. At the same time, the limit block slides along the surface of the annular guide rod together with the drum. When the limit block contacts the fixed plate, the fixed plate will prevent the drum from continuing to rotate through the limit block, thereby ensuring that the inclination angle of the spoiler fan and the agitator is within a reasonable range.

[0027] (VII) The device is provided with an injection component. When the airflow passes through the connecting elbow and enters the injection pipe, the airflow pushes the air guide tube to slide along the inner side of the annular block, forcing the compression spring to be compressed, thereby making the injection hole protrude from the annular block. At this time, the airflow can be ejected outward through the injection hole. When no airflow passes, the air guide tube automatically resets under the elastic force of the compression spring, thereby preventing the culture solution from flowing back through the injection hole.

[0028] (VIII) The device is provided with an injection component. The pressure of the airflow will affect the sliding degree of the air guide cylinder, so that the airflow can be ejected outward through more injection holes, thereby adjusting the gas injection amount. When the airflow passes through the ventilation ring, as the inner diameter of the ventilation ring gradually decreases, the reduction in the flow cross-sectional area will cause the gas flow rate to increase. The accelerated airflow will enter the exhaust pipe along the spiral dredging rod and finally eject outward in a spiral shape. The high-speed spiral airflow can more effectively disperse the gas into the culture medium. The high-speed airflow can break larger bubbles into smaller bubbles, increase the specific surface area of ​​the bubbles, and thus improve the dissolution efficiency of the gas in the culture medium.

[0029] (IX) The device is provided with a spiral dredging rod, along which high-speed airflow flows, which can flush the inner wall of the exhaust pipe. At the same time, as the air guide tube slides on the inner wall of the injection pipe, it drives the ventilation ring to move synchronously through the connecting rod, thereby making the spiral dredging rod slide along the inner wall of the exhaust pipe. Combined with the flushing effect of the airflow, it can also prevent the exhaust pipe from being blocked.

[0030] (10) The equipment is provided with an exhaust pipe. When the airflow is ejected from the exhaust pipe, it can just spray on the surface of the stirring paddle. When the airflow is sprayed on the surface of the stirring paddle, it has a certain impact force, which can wash away some impurities, bio-based materials or metabolites attached to the surface of the stirring paddle. This plays a certain self-cleaning role, reduces the accumulation of dirt on the surface of the stirring paddle, reduces the possibility of affecting the performance of the stirring paddle due to the attachment of impurities, and also helps to keep the culture environment clean.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example: See Figure 1-9The present invention provides a technical solution: a bio-based material cultivation device that is easy to ventilate, comprising a base 1, and an electric heating platform 2 fixed on the top of the base 1, and also comprising: a culture tank 3, the culture tank 3 is fixedly connected to the top of the electric heating platform 2, the top of the culture tank 3 is fixedly connected to an air compressor 4, the output end of the air compressor 4 is fixedly connected to a ventilation device 5, the top of the base 1 is fixedly connected to a drug adding cartridge 6 and an exhaust valve 7, the top of the culture tank 3 away from the exhaust valve 7 is rotatably connected to a cover plate 8, and the bottom of the culture tank 3 is fixedly connected to a drain pipe 9; a sterilant is added to the culture tank 3 through the drug adding cartridge 6 to provide a sterile environment for the cultivation of bio-based materials, and then the cover plate 8 is opened to pour the culture solution of the bio-based material into the culture tank 3. The electric heating platform 2 on the top of the base 1 can heat the culture tank 3 and adjust the culture solution to a suitable culture temperature; the air compressor 4 is started to compress the air and output it to the ventilation device 5. The compressed air is filtered by the filter component 52 and then sent to the stirring component 54, and then sprayed into the culture tank 3 through the stirring component 54. At this time, under the reverse thrust of the airflow, the stirring component 54 can drive the air guide tube 51 to rotate, so that the culture solution is evenly mixed, and the full contact between the bio-based material and the nutrients and gas is promoted, which is beneficial to the growth and metabolism of the bio-based material. When the pressure in the culture tank 3 increases, the gas in the culture tank 3 can be discharged through the exhaust valve 7. When the culture tank 3 is not in use, the fluid in the culture tank 3 can be discharged through the drain pipe 9

[0043] The ventilation device 5 includes an air duct 51, a filter assembly 52 is fixedly connected to the top of the air duct 51, a stirring assembly 54 is fixedly connected to the outer wall of the air duct 51, and a spiral air duct groove 53 is opened in the inner wall of the ventilation device 5; the outer side of the ventilation device 5 is rotatably connected to the center of the culture tank 3, the exhaust valve 7 is located on the side of the medicine adding cartridge 6 away from the ventilation device 5, the outer side of the air duct 51 is rotatably connected to the inner side of the culture tank 3, the top of the filter assembly 52 is fixedly connected to the output end of the air compressor 4, and the bottom of the filter assembly 52 is fixedly connected to the center of the top of the culture tank 3. When air enters the air duct 51 through the filter assembly 52 and flows along the spiral air duct groove 53, when the air flows in the spiral air duct groove 53, according to the principles of fluid mechanics, the air will generate a tangential force on the inner wall of the air duct 51. This tangential force will form a torque, causing the air guide tube 51 to tend to rotate around its axis, and then cooperate with the reverse thrust of the stirring assembly 54 to drive the air guide tube 51 to rotate, thereby improving the energy utilization efficiency of the equipment.

[0044] The filter assembly 52 includes a protective shell 521, the inner side of which is fixedly connected to an aggregate shell 523, the top of which is fixedly connected to a conical filter plate 522, and the inner side of the aggregate shell 523 is fixedly connected to a guide plate 524; the bottom of the protective shell 521 is fixedly connected to the top of the culture tank 3, the inner side of the aggregate shell 523 is rotatably connected to an annular scraper 526, the outer side of the protective shell 521 is slidably connected to a cleaning plate 527, the inner side of the annular scraper 526 is fixedly connected to the top of the air guide pipe 51, the top of the protective shell 521 is fixedly connected to the output end of the air compressor 4, and an air guide hole 525 is opened in the wall of the aggregate shell 523. When the air flow enters the filter assembly 52, the air first passes through the protective shell 521 and enters the aggregate shell 523. The conical filter plate 522 can initially intercept larger impurities in the air. The impurities are trapped and rolled down along the outer wall of the conical filter plate 522 into the aggregate shell 523 under the impact of the airflow. The guide plates 524 are tilted downward and arranged in a staggered manner in the aggregate shell 523. When the airflow passes through the guide plates 524, it will be continuously guided and blocked, and its flow rate and flow direction will change multiple times, thereby weakening the upward force of the airflow on the impurities and effectively preventing the impurities from being recoiled. The air guide holes 525 are opened on the guide plates 524. At the rear, when impurities move toward the air guide hole 525 under the action of the air flow, the speed and direction of the air flow change, making it difficult for the impurities to obtain sufficient power to enter the air guide pipe 51 through the air guide hole 525, thereby further improving the interception efficiency of the filter component 52 for impurities. At the same time, the annular scraper 526 rotates with the air guide pipe 51, and can push the impurities in the aggregate shell 523 to the side close to the cleaning plate 527. When the cleaning plate 527 slides upward, the impurities inside the protective shell 521 can be cleared out.

[0045] The stirring assembly 54 includes an air guide ring 541, the outer side of the air guide ring 541 is fixedly connected to a torsion component 542, the outer side of the torsion component 542 is fixedly connected to a spoiler fan 543, both sides of the spoiler fan 543 are rotatably connected to movable rods 544, the outer side of the air guide ring 541 is fixedly connected to an air jet component 545, both sides of the air jet component 545 are fixedly connected to mounting frames 547, the inner side of the mounting frame 547 is rotatably connected to an arc spoiler plate 548, and the side of the air jet component 545 away from the air guide ring 541 is fixedly connected to The stirring paddle 546 and the inner side of the air guide ring 541 are fixedly connected to the outer side of the air guide pipe 51. The end of the movable rod 544 away from the spoiler fan 543 is rotatably connected to the outer side of the mounting frame 547. The torsion component 542 and the jet component 545 are arranged in a ring along the central axis of the air guide ring 541. The air enters the air guide ring 541 from the air guide pipe 51 and then is ejected through the jet component 545. At this time, the reverse thrust of the jet component 545 drives the stirring assembly 54 to rotate as a whole. As the spoiler fan 543 and the stirring paddle 546 rotate, the stirring assembly 54 rotates. Rotation will produce interaction between them and the culture solution. By setting the torsion component 542, the spoiler fan 543 can adaptively adjust the deflection angle as the viscosity of the culture solution changes during rotation. In this process, the spoiler fan 543 forms a quadrilateral mechanism between the movable rod 544 and the mounting frame 547. When the spoiler fan 543 is deflected, the spoiler fan 543 will drive the mounting frame 547 to deflect synchronously with the jet component 545 as the base point through the movable rod 544, so that the jet component 545 will drive the stirring paddle 546 to deflect synchronously when deflecting, ensuring that the bio-based materials can obtain good culture conditions under different viscosity environments. At the same time, by setting the arc spoiler 548, when the arc spoiler 548 rotates with the mounting frame 547, the arc spoiler 548 can rotate relative to the mounting frame 547 under the push of the culture solution, changing the original motion trajectory of the culture solution, so that the culture solution forms complex vortices and turbulence, increasing the degree of fluid turbulence, and facilitating the full contact between the bio-based materials and nutrients and gases.

[0046] The torsion component 542 includes a fixed block 421, the outer side of the fixed block 421 is rotatably connected to a rotating cylinder 422, the inner side of the rotating cylinder 422 is fixedly connected to a torsion spring 423, the outer side of the fixed block 421 is fixedly connected to a fixed plate 424, the inner side of the fixed plate 424 is fixedly connected to an annular guide rod 425, the outer side of the annular guide rod 425 is slidably connected to a limiting block 426, the outer side of the fixed block 421 is fixedly connected to the outer side of the air guide ring 541, the outer side of the rotating cylinder 422 is fixedly connected to the outer side of the spoiler fan 543, and the end of the torsion spring 423 away from the rotating cylinder 422 is fixedly connected to the fixed block 4 21, the inner side of the drum 422 is fixedly connected to the outer side of the limit block 426. When the spoiler fan 543 deflects, the drum 422 deflects relative to the fixed block 421, thereby causing the torsion spring 423 to twist and store force. At the same time, the limit block 426 slides along the surface of the annular guide rod 425 with the drum 422. When the limit block 426 contacts the fixed plate 424, the fixed plate 424 will prevent the drum 422 from continuing to rotate through the limit block 426, thereby ensuring that the inclination angle of the spoiler fan 543 and the stirring paddle 546 is within a reasonable range. This can prevent the inclination angle of the spoiler fan 543 and the stirring paddle 546 from changing excessively due to excessive airflow or sudden changes in the resistance of the culture fluid, thereby ensuring the stable operation of the stirring assembly 54 and the safety of the equipment.

[0047] The jet component 545 includes a jet pipe 451, the outer side of the jet pipe 451 is rotatably connected to a connecting elbow 452, the inner wall of the jet pipe 451 is fixedly connected to an annular stopper 454, the inner side of the annular stopper 454 is fixedly connected to a compression spring 455, the end of the compression spring 455 away from the annular stopper 454 is fixedly connected to an air guide cylinder 453, the outer side of the jet pipe 451 is fixedly connected to an exhaust pipe 459, the end of the connecting elbow 452 away from the air guide cylinder 451 is fixedly connected to the outer side of the air guide ring 541, and the jet pipe 451 is fixedly connected to the outer side of the air guide ring 541. The outer wall of the ejection tube 453 is slidably connected to the inner wall of the gas cylinder 453, the outer wall of the gas cylinder 453 is slidably connected to the inner side of the annular stopper 454, a jet hole 450 is provided in the wall of the gas cylinder 453, a connecting rod 456 is fixedly connected to the outer side of the gas cylinder 453, a ventilation ring 457 is fixedly connected to the end of the connecting rod 456 away from the gas cylinder 453, a spiral dredging rod 458 is fixedly connected to the outer side of the ventilation ring 457, the outer wall of the spiral dredging rod 458 is slidably connected to the inner wall of the exhaust pipe 459, and the ventilation ring 457 The outer wall of is slidably connected with the inner wall of the injection tube 451. When the airflow enters the injection tube 451 through the connecting elbow 452, the airflow pushes the air guide cylinder 453 to slide along the inner side of the annular block 454, forcing the compression spring 455 to be compressed, thereby making the injection hole 450 protrude from the annular block 454. At this time, the airflow can be ejected outward through the injection hole 450. When there is no airflow passing through, the air guide cylinder 453 automatically resets under the elastic force of the compression spring 455, which can prevent the culture solution from flowing back through the injection hole 450. The pressure of the air flow will affect the sliding degree of the air guide tube 453, so that the air flow can be ejected outward through more injection holes 450, thereby adjusting the gas injection amount. When the air flow passes through the ventilation ring 457, as the inner diameter of the ventilation ring 457 gradually decreases, the reduction in the flow cross-sectional area will cause the gas flow rate to increase, and the accelerated air flow will follow the spiral dredging rod 458 into the exhaust pipe 459, and finally be ejected outward in a spiral shape. The high-speed spiral airflow can more effectively disperse the gas into the culture medium. High-speed airflow can break larger bubbles into smaller bubbles, increase the specific surface area of ​​the bubbles, and thus improve the dissolution efficiency of the gas in the culture medium. During this process, the high-speed airflow flows along the spiral dredging rod 458, which can flush the inner wall of the exhaust pipe 459. At the same time, as the air guide tube 453 slides on the inner wall of the injection tube 451, it drives the ventilation ring 457 to move synchronously through the connecting rod 456, thereby making the spiral dredging rod 458 slide along the inner wall of the exhaust pipe 459. Combined with the flushing effect of the airflow, it can also prevent the exhaust pipe 459 from being blocked; when the airflow is ejected from the exhaust pipe 459, it can just spray on the surface of the stirring paddle 546. When the airflow is sprayed on the surface of the stirring paddle 546, it has a certain impact force, which can flush away some impurities, bio-based materials or metabolites attached to the surface of the stirring paddle 546.This provides a certain degree of self-cleaning effect, reduces the accumulation of dirt on the surface of the stirring paddle 546, reduces the possibility of the performance of the stirring paddle 546 being affected by the adhesion of impurities, and also helps to keep the culture environment clean.

[0048] Working principle:

[0049] When in use, sterilizing agent is added into the culture tank 3 through the drug adding cartridge 6 to provide a sterile environment for the cultivation of bio-based materials, and then the cover plate 8 is opened to pour the culture solution of the bio-based materials into the culture tank 3. The electric heating platform 2 on the top of the base 1 can heat the culture tank 3 and adjust the culture solution to a suitable culture temperature;

[0050] The air compressor 4 starts to compress the air and output it to the ventilation device 5. The compressed air is filtered by the filter component 52 and then sent to the stirring component 54. Then, it is sprayed into the culture tank 3 through the stirring component 54. At this time, under the reverse thrust of the airflow, the stirring component 54 can drive the air guide tube 51 to rotate, so that the culture liquid is evenly mixed, and the full contact between the bio-based materials and the nutrients and gases is promoted, which is beneficial to the growth and metabolism of the bio-based materials. When the pressure in the culture tank 3 increases, the gas in the culture tank 3 can be discharged through the exhaust valve 7. When the culture tank 3 is not in use, the fluid in the culture tank 3 can be discharged through the drain pipe 9.

[0051] When air enters the air guide tube 51 through the filter assembly 52 and flows along the spiral air guide groove 53, the air will generate a tangential force on the inner wall of the air guide tube 51 according to the principle of fluid mechanics when the air flows in the spiral air guide groove 53. This tangential force will form a torque, causing the air guide tube 51 to tend to rotate around its axis, and then cooperate with the reverse thrust of the stirring assembly 54 to drive the air guide tube 51 to rotate, thereby improving the energy utilization efficiency of the equipment.

[0052] When the airflow enters the filter assembly 52, the air first passes through the protective shell 521 and enters the aggregate shell 523. The conical filter plate 522 can initially intercept larger impurities in the air. The impurities are trapped and roll down along the outer wall of the conical filter plate 522 into the aggregate shell 523 under the impact of the airflow. The guide plates 524 are tilted downward and arranged in a staggered manner in the aggregate shell 523. When the airflow passes through the guide plates 524, it will be continuously guided and blocked, and its flow rate and flow direction will change multiple times, thereby weakening the upward force of the airflow on the impurities and effectively preventing the impurities from being recoiled.

[0053] The air guide hole 525 is opened at the rear of the guide plate 524. When impurities move toward the air guide hole 525 under the action of the air flow, the speed and direction of the air flow change, making it difficult for the impurities to obtain sufficient power to enter the air guide pipe 51 through the air guide hole 525, thereby further improving the interception efficiency of the filter component 52 for impurities. At the same time, the annular scraper 526 rotates with the air guide pipe 51, and can push the impurities in the aggregate shell 523 to the side close to the cleaning plate 527. When the cleaning plate 527 slides upward, the impurities inside the protective shell 521 can be cleared out.

[0054] Air enters the air guide ring 541 from the air guide tube 51, and then is ejected through the jet component 545. At this time, the reverse thrust of the jet component 545 drives the stirring assembly 54 to rotate as a whole. As the spoiler fan 543 and the stirring paddle 546 rotate, they interact with the culture solution. By setting the torsion component 542, the spoiler fan 543 can adaptively adjust the deflection angle as the viscosity of the culture solution changes during rotation. In this process, the spoiler fan 543 forms a quadrilateral mechanism between the movable rod 544 and the mounting frame 547. When the spoiler fan 543 deflects, the spoiler fan 543 will drive the mounting frame 547 to deflect synchronously with the jet component 545 as the base point through the movable rod 544, so that the jet component 545 will drive the stirring paddle 546 to deflect synchronously when deflecting, thereby ensuring that the bio-based materials can obtain good culture conditions under different viscosity environments.

[0055] At the same time, by setting the arc-shaped spoiler 548, when the arc-shaped spoiler 548 rotates with the mounting frame 547, the arc-shaped spoiler 548 can rotate relative to the mounting frame 547 under the push of the culture fluid, changing the original motion trajectory of the culture fluid, so that the culture fluid forms complex vortices and turbulence, increasing the degree of fluid turbulence, which is beneficial to the full contact between bio-based materials and nutrients and gases.

[0056] When the spoiler fan 543 deflects, the drum 422 deflects relative to the fixed block 421, thereby causing the torsion spring 423 to twist and accumulate force. At the same time, the stop block 426 slides along the surface of the annular guide rod 425 along with the drum 422. When the stop block 426 contacts the fixed plate 424, the fixed plate 424 will prevent the drum 422 from continuing to rotate through the stop block 426, thereby ensuring that the inclination angles of the spoiler fan 543 and the stirring paddle 546 are within a reasonable range. This can prevent the inclination angles of the spoiler fan 543 and the stirring paddle 546 from changing excessively due to excessive airflow or sudden changes in the resistance of the culture fluid, thereby ensuring the stable operation of the stirring assembly 54 and the safety of the equipment.

[0057] When the air flow passes through the connecting bend 452 and enters the injection tube 451, the air flow pushes the air guide cylinder 453 to slide along the inner side of the annular block 454, forcing the compression spring 455 to be compressed, thereby causing the injection hole 450 to protrude from the annular block 454. At this time, the air flow can be ejected outward through the injection hole 450. When no air flow passes through, the air guide cylinder 453 automatically resets under the elastic force of the compression spring 455, thereby preventing the culture fluid from flowing back through the injection hole 450.

[0058] At the same time, the pressure of the airflow will affect the sliding degree of the air guide cylinder 453, so that the airflow can be ejected outward through more injection holes 450, thereby adjusting the gas injection amount. When the airflow passes through the ventilation ring 457, as the inner diameter of the ventilation ring 457 gradually decreases, the reduction in the flow cross-sectional area will cause the gas flow rate to increase, and the accelerated airflow will enter the exhaust pipe 459 along the spiral dredging rod 458, and finally eject outward in a spiral shape. The high-speed spiral airflow can more effectively disperse the gas into the culture solution. The high-speed airflow can break larger bubbles into smaller bubbles, increase the specific surface area of ​​the bubbles, and thus improve the dissolution efficiency of the gas in the culture solution.

[0059] During this process, the high-speed airflow flows along the spiral dredging rod 458, which can flush the inner wall of the exhaust pipe 459. At the same time, as the air guide cylinder 453 slides on the inner wall of the injection pipe 451, it drives the ventilation ring 457 to move synchronously through the connecting rod 456, thereby making the spiral dredging rod 458 slide along the inner wall of the exhaust pipe 459. The flushing effect of the airflow can also prevent the exhaust pipe 459 from being blocked.

[0060] When the airflow is ejected from the exhaust pipe 459, it can just be sprayed on the surface of the stirring paddle 546. When the airflow is sprayed on the surface of the stirring paddle 546, it has a certain impact force, which can wash away some impurities, bio-based materials or metabolic products attached to the surface of the stirring paddle 546. This plays a certain self-cleaning role, reduces the accumulation of dirt on the surface of the stirring paddle 546, reduces the possibility of affecting the performance of the stirring paddle 546 due to the attachment of impurities, and also helps to keep the culture environment clean.
