Description

Technical Field

[0001] This invention relates to the field of bio-based material cultivation technology, specifically to a bio-based material cultivation device that is easy to ventilate. Background Technology

[0002] In the field of biotechnology today, the cultivation and research of bio-based materials has significant strategic importance and broad application prospects, and it is widely used in multiple industries such as medicine, environmental protection, and energy. During the cultivation process, bio-based materials require oxygen to participate in various biochemical reactions within cells in order to synthesize the substances needed for their own growth, provide energy, and maintain normal physiological functions.

[0003] In existing technologies, the current aeration direction of bio-based material cultivation equipment is singular, making it impossible to flexibly adjust the direction and angle of the air jet according to the actual needs of bio-based material cultivation and changes in the properties of the culture medium. This results in uneven gas distribution in the culture medium, preventing the bio-based material from fully contacting oxygen and other gases, making it difficult to ensure effective gas diffusion and mixing, and further limiting the growth and development of the bio-based material. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a bio-based material cultivation device that facilitates ventilation, solving the problem of ineffective gas diffusion and mixing in existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ventilated bio-based material cultivation device, comprising a base and an electric heating platform fixed to the top of the base, and further comprising: a cultivation tank fixedly connected to the top of the electric heating platform, an air compressor fixedly connected to the top of the cultivation tank, a ventilation device fixedly connected to the output end of the air compressor, a drug-adding cylinder and an exhaust valve fixedly connected to the top of the base, a cover plate rotatably connected to the top of the cultivation tank on the side away from the exhaust valve, and a drain pipe fixedly connected to the bottom of the cultivation tank; sterile agent is added to the cultivation tank through the drug-adding cylinder to provide a sterile environment for the cultivation of bio-based materials, and then the cover plate is opened to pour the culture medium of the bio-based materials into the cultivation tank. The electric heating platform on the top of the base can heat the cultivation tank and adjust the culture medium to a suitable cultivation temperature.

[0006] The ventilation device includes an air guide pipe, which is rotatably connected at the center of the culture tank [1]. A filter assembly is fixedly connected to the top of the air guide pipe, and a stirring assembly is fixedly connected to the outer wall of the air guide pipe. A spiral air guide groove is opened in the inner wall of the ventilation device. After the compressed air is filtered by the filter assembly, it is sent to the stirring assembly and then sprayed into the culture tank by the stirring assembly. At this time, under the reverse thrust of the airflow, the stirring assembly can drive the air guide pipe to rotate, so that the culture liquid is mixed evenly, promotes the full contact between the bio-based material and nutrients and gases, and is beneficial to the growth and metabolism of the bio-based material.

[0007] The filter assembly includes a protective shell, an inner shell of which is fixedly connected. A conical filter plate is fixedly connected to the top of the collection shell, and a guide plate is fixedly connected to the inner side of the collection shell. The guide plates are inclined downward and staggered inside the collection shell. When the airflow passes through the guide plates, it is continuously guided and blocked, and its flow rate and direction change multiple times, thereby weakening the upward force of the airflow on impurities and effectively preventing impurities from being backflushed. The air guide hole is opened behind the guide plate. When impurities move towards the air guide hole under the action of airflow, the speed and direction of the airflow change, making it difficult for impurities to obtain enough power to enter the air guide pipe through the air guide hole, thereby further improving the interception efficiency of the filter assembly for impurities.

[0008] The stirring assembly includes an air guide ring, a torsion component fixedly connected to the outer side of the air guide ring, a baffle fan fixedly connected to the outer side of the torsion component, movable rods rotatably connected to both sides of the baffle fan, an air jet component fixedly connected to the outer side of the air guide ring, mounting brackets fixedly connected to both sides of the air jet component, an arc-shaped baffle plate rotatably connected to the inner side of the mounting bracket, and a stirring paddle fixedly connected to the side of the air jet component away from the air guide ring. Air enters the air guide ring from the air guide pipe and is then ejected through the air jet component. At this time, the thrust of the air jet component drives the entire stirring assembly to rotate. As the baffle fan and the stirring paddle rotate, they interact with the culture medium. By setting the torsion component, the baffle fan can adaptively adjust its deflection angle according to the change in the viscosity of the culture medium during rotation.

[0009] 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. The spoiler fan forms a quadrilateral mechanism between the movable rod and the mounting frame. When the spoiler fan deflects, the spoiler fan will drive the mounting frame to deflect synchronously with the jet component as the base point through the movable rod, thereby causing the jet component to drive the agitator to deflect synchronously when it deflects.

[0010] Preferably, the exhaust valve is located on the side of the dosing cylinder away from the ventilation device, 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 inside the culture tank increases, the gas inside the culture tank can be discharged through the exhaust valve. When the culture tank is not in use, the fluid inside the culture tank can be discharged through the drain pipe.

[0011] Preferably, the bottom of the protective shell is fixedly connected to the top of the culture tank, an annular scraper is rotatably connected to the inner side of the collection shell, a cleaning plate is slidably connected to the outer side of the protective shell, the inner side of the annular 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 an air guide hole is opened in the wall of the collection shell. The annular scraper rotates together with the air guide pipe, which can push the impurities in the collection shell to the side close to the cleaning plate. When the cleaning plate is slid upward, the impurities inside the protective shell can be cleaned out.

[0012] Preferably, the torsion component includes a fixed block, a rotating cylinder rotatably connected to the outer side of the fixed block, a torsion spring fixedly connected to the inner side of the rotating cylinder, a fixed plate fixedly connected to the outer side of the fixed block, an annular guide rod fixedly connected to the inner side of the fixed plate, and a limit block slidably connected to the outer side of the annular guide rod. When the spoiler fan deflects, the rotating cylinder deflects relative to the fixed block, thereby causing the torsion spring to torsionally store force. At the same time, the limit block slides along the surface of the annular guide rod together with the rotating cylinder.

[0013] 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 cylinder is fixedly connected to the outer side of the turbulence fan, the end of the torsion spring away from the rotating cylinder is fixedly connected to the outer side of the fixed block, and the inner side of the rotating cylinder is fixedly connected to the outer side of the limiting block. When the limiting block contacts the fixed plate, the fixed plate will prevent the rotating cylinder from continuing to rotate through the limiting block, thereby ensuring that the tilt angle of the turbulence fan and the stirring paddle is within a reasonable range.

[0014] Preferably, the jet component includes a jet pipe, a connecting bend is rotatably connected to the outer side of the jet pipe, an annular stop is fixedly connected to the inner wall of the jet pipe, a compression spring is fixedly connected to the inner side of the annular stop, an air guide tube is fixedly connected to the end of the compression spring away from the annular stop, and an exhaust pipe is fixedly connected to the outer side of the jet pipe. When the airflow enters the jet pipe through the connecting bend, the airflow pushes the air guide tube to slide along the inner side of the annular stop, forcing the compression spring to be compressed, thereby causing the jet hole to protrude from the annular stop, and the airflow can then be ejected outward through the jet hole.

[0015] Preferably, the end of the connecting bend 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 block, and injection holes are opened in the wall of the air guide cylinder. The pressure of the airflow will affect the degree of sliding of the air guide cylinder, thereby allowing the airflow to be ejected outward through more injection holes, and thus the gas injection volume can also be adjusted.

[0016] Preferably, a connecting rod is fixedly connected to the outer side of the air guide cylinder, and a venting ring is fixedly connected to the end of the connecting rod away from the air guide cylinder. A spiral cleaning rod is fixedly connected to the outer side of the venting ring. The outer wall of the spiral cleaning rod is slidably connected to the inner wall of the exhaust pipe, and the outer wall of the venting ring is slidably connected to the inner wall of the injection pipe. When the airflow is ejected from the exhaust pipe, it can just spray onto the surface of the stirring paddle. When the airflow sprays onto the surface of the stirring paddle, 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.

[0017] This invention provides a bio-based material cultivation device that facilitates ventilation. It offers the following advantages:

[0018] (i) By incorporating a ventilation system, when air enters the air duct through the filter assembly and flows along the spiral air guide groove, the air exerts a tangential force on the inner wall of the air duct according to fluid mechanics principles. This tangential force generates a torque, causing the air duct to tend to rotate around its axis. This torque, combined with the counter-thrust of the stirring assembly, drives the air duct to rotate, thus improving the energy efficiency of the equipment.

[0019] (ii) By setting up a filter assembly, the conical filter plate can initially intercept larger impurities in the air. The impurities are trapped and rolled down the outer wall of the conical filter plate into the collection shell under the impact of the airflow. The guide plates are inclined downward and staggered in the collection shell. When the airflow passes through the guide plates, it will be continuously guided and blocked, and its flow velocity 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 flushed back.

[0020] (III) By setting up a filter assembly, the air guide hole is opened behind the guide plate. When impurities move towards the air guide hole under the action of airflow, the speed and direction of airflow change, making it difficult for impurities to obtain enough 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 collection shell to the side close to the cleaning plate. When the cleaning plate is slid upward, the impurities inside the protective shell can be cleaned out.

[0021] (iv) The equipment is equipped with a stirring component. Air enters the air guide ring from the air guide pipe and is then ejected through the jet component. At this time, the thrust of the jet component drives the stirring component to rotate as a whole. The turbulence fan forms a quadrilateral mechanism between the movable rod and the mounting frame. When the turbulence fan deflects, the turbulence fan will drive the mounting frame to deflect synchronously with the jet component as the base point through the movable rod. This will cause the jet component to deflect synchronously with the stirring paddle, ensuring that the bio-based material can obtain good cultivation conditions under different viscosity environments.

[0022] (v) By setting up an arc-shaped baffle, when the arc-shaped baffle rotates with the mounting frame, the arc-shaped baffle can rotate relative to the mounting frame under the push of the culture medium, changing the original movement trajectory of the culture medium, thereby forming complex eddies and turbulence in the culture medium, increasing the degree of fluid turbulence, which is conducive to the full contact between bio-based materials and nutrients and gases.

[0023] (vi) By setting a torsion component, when the turbulence fan deflects, the rotating drum deflects relative to the fixed block, thereby causing the torsion spring to torsion and store force. At the same time, the limiting block slides along the surface of the annular guide rod together with the rotating drum. When the limiting block contacts the fixed plate, the fixed plate will prevent the rotating drum from continuing to rotate through the limiting block, thereby ensuring that the tilt angle of the turbulence fan and the agitator is within a reasonable range.

[0024] (vii) By setting up an air jet component, when the airflow enters the jet pipe through the connecting bend, 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 causing the jet hole to protrude from the annular block. At this time, the airflow can be ejected outward through the jet hole. When no airflow passes through, the air guide tube automatically resets under the elastic force of the compression spring, which can prevent the culture medium from flowing back through the jet hole.

[0025] (viii) This device, by incorporating jet components, allows the airflow pressure to affect the sliding degree of the air guide tube, thus enabling the airflow to be ejected outward through more jet holes. This also allows for adjustment of the gas injection volume. As the airflow passes through the ventilation ring, the decreasing inner diameter of the ring leads to a reduction in the flow cross-sectional area, resulting in an increase in gas velocity. The accelerated airflow then flows along the spiral unblocking rod into the exhaust pipe, ultimately ejecting outward in a spiral shape. This high-speed spiral airflow effectively disperses the gas into the culture medium. The high-speed airflow can break larger bubbles into smaller ones, increasing the specific surface area of ​​the bubbles and thus improving the gas dissolution efficiency in the culture medium.

[0026] (ix) The device is equipped with a spiral cleaning rod. The high-speed airflow flows along the spiral cleaning rod, 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, which in turn makes the spiral cleaning 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.

[0027] (x) This device features an exhaust pipe. When the airflow exits from the exhaust pipe, it directly hits the surface of the agitator. The impact force of the airflow on the agitator surface washes away impurities, bio-based materials, or metabolic products adhering to the agitator surface. This provides a degree of self-cleaning, reducing the accumulation of dirt on the agitator surface and lowering the possibility of impurities affecting the agitator's performance. It also helps maintain a clean culture environment. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example: Please refer to Figure 1-9This invention provides a technical solution: a bio-based material cultivation device with easy ventilation, including a base 1 and an electric heating platform 2 fixed on the top of the base 1, and further including: a cultivation tank 3, which is fixedly connected to the top of the electric heating platform 2, an air compressor 4 is fixedly connected to the top of the cultivation tank 3, a ventilation device 5 is fixedly connected to the output end of the air compressor 4, a drug-adding cylinder 6 and an exhaust valve 7 are fixedly connected to the top of the base 1, a cover plate 8 is rotatably connected to the top of the cultivation tank 3 on the side away from the exhaust valve 7, and a drain pipe 9 is fixedly connected to the bottom of the cultivation tank 3; a sterile agent is added into the cultivation tank 3 through the drug-adding cylinder 6 to provide a sterile environment for the cultivation of bio-based materials, and then the culture medium of the bio-based materials is poured into the cultivation tank 3 by opening the cover plate 8. The electric heating platform 2 on top of the base 1 heats the culture tank 3 and adjusts the culture medium to a suitable culture temperature. The air compressor 4 starts, compresses air and outputs it to the ventilation device 5. The compressed air is filtered by the filter assembly 52 and then sent to the stirring assembly 54. After passing through the stirring assembly 54, the air is sprayed into the culture tank 3. At this time, under the reverse thrust of the airflow, the stirring assembly 54 can drive the air guide tube 51 to rotate, so that the culture medium is mixed evenly, promoting full contact between the bio-based material and nutrients and gases, which is beneficial to the growth and metabolism of the bio-based material. When the pressure inside the culture tank 3 increases, the gas inside the culture tank 3 can be discharged through the exhaust valve 7. When the culture tank 3 is not in use, the fluid inside the culture tank 3 can be discharged through the drain pipe 9.

[0040] The ventilation device 5 includes an air guide pipe 51, which is rotatably connected at the center of the culture tank 3 [2]. A filter assembly 52 is fixedly connected to the top of the air guide pipe 51, and a stirring assembly 54 is fixedly connected to the outer wall of the air guide pipe 51. A spiral air guide groove 53 is opened in the inner wall of the ventilation device 5. The exhaust valve 7 is located on the side of the dosing cylinder 6 away from the ventilation device 5. The outer side of the air guide pipe 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. 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 guide pipe 51 through the filter assembly 52 and flows along the spiral air guide groove 53, the air will exert a tangential force on the inner wall of the air guide pipe 51 when it flows in the spiral air guide groove 53, according to the principle of fluid mechanics. This tangential force will generate a torque, causing the air guide pipe 51 to tend to rotate around its axis. This torque, combined with the counter-thrust of the stirring component 54, will drive the air guide pipe 51 to rotate, thereby improving the energy efficiency of the equipment.

[0041] The filter assembly 52 includes a protective shell 521, a collection shell 523 fixedly connected to the inner side of the protective shell 521, a conical filter plate 522 fixedly connected to the top of the collection shell 523, and a guide plate 524 fixedly connected to the inner side of the collection shell 523. The bottom of the protective shell 521 is fixedly connected to the top of the culture tank 3. An annular scraper 526 is rotatably connected to the inner side of the collection shell 523. A cleaning plate 527 is slidably connected to the outer side of the protective shell 521. 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. An air guide hole 525 is opened in the wall of the collection shell 523. When the airflow enters the filter assembly 52, the air first passes through the protective shell 521 and enters the collection shell 523. The conical filter plate 522 can initially intercept larger impurities in the air. The impurities are trapped and, under the impact of the airflow, roll down the outer wall of the conical filter plate 522 into the collection shell 523. The guide plates 524 are inclined downwards and staggered within the collection shell 523. As the airflow passes through the guide plates 524, it is continuously guided and blocked, causing multiple changes in its velocity and direction. This weakens the upward force of the airflow on the impurities, effectively preventing them from being backflushed. The air guide holes 525 are located on the guide plates 524. Behind, when impurities move towards the air guide hole 525 under the action of airflow, the speed and direction of the airflow change, making it difficult for impurities to obtain enough 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 together with the air guide pipe 51, which can push the impurities in the collection shell 523 to the side close to the cleaning plate 527. When the cleaning plate 527 is slid upward, the impurities inside the protective shell 521 can be cleaned out.

[0042] The stirring assembly 54 includes an air guide ring 541, a torsion member 542 fixedly connected to the outer side of the air guide ring 541, a baffle fan 543 fixedly connected to the outer side of the torsion member 542, movable rods 544 rotatably connected to both sides of the baffle fan 543, an air jet member 545 fixedly connected to the outer side of the air guide ring 541, mounting brackets 547 fixedly connected to both sides of the air jet member 545, an arc-shaped baffle 548 rotatably connected to the inner side of the mounting bracket 547, and a fixedly connected [missing information] on the side of the air jet member 545 away from the air guide ring 541. The agitator 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 bracket 547. The torsion component 542 and the jet component 545 are both arranged in a ring along the central axis of the air guide ring 541. Air enters the air guide ring 541 from the air guide pipe 51 and is then ejected through the jet component 545. At this time, the reverse thrust of the jet component 545 drives the agitator assembly 54 to rotate as a whole. The spoiler fan 543 and the agitator 546... As they rotate, they interact with the culture medium. By setting a torsion component 542, the turbulence fan 543 can adaptively adjust its deflection angle according to the change in the viscosity of the culture medium during rotation. In this process, the turbulence fan 543 forms a quadrilateral mechanism with the mounting frame 547 through the movable rod 544. When the turbulence fan 543 deflects, it will drive the mounting frame 547 to deflect synchronously with the jet component 545 as the base point through the movable rod 544. In turn, the jet component 545 will drive the stirring paddle 546 to deflect synchronously when it deflects, ensuring that the bio-based material can obtain good culture conditions under different viscosity environments. At the same time, by setting an arc-shaped turbulence plate 548, when the arc-shaped turbulence plate 548 rotates with the mounting frame 547, the arc-shaped turbulence plate 548 can rotate relative to the mounting frame 547 under the push of the culture medium, changing the original movement trajectory of the culture medium, thereby forming complex eddies and turbulence in the culture medium, increasing the degree of fluid turbulence, which is conducive to the full contact between the bio-based material and nutrients and gases.

[0043] The torsion component 542 includes a fixed block 421, a rotating cylinder 422 rotatably connected to the outer side of the fixed block 421, a torsion spring 423 fixedly connected to the inner side of the rotating cylinder 422, a fixed plate 424 fixedly connected to the outer side of the fixed block 421, an annular guide rod 425 fixedly connected to the inner side of the fixed plate 424, a limit block 426 slidably connected to the outer side of the annular guide rod 425, a fixed outer side of the fixed block 421 fixedly connected to the outer side of the air guide ring 541, a fixed outer side of the rotating cylinder 422 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 connected to the fixed block 421. The outer side of the fixed block 421 is fixedly connected to the fixed block 421, and the inner side of the rotating drum 422 is fixedly connected to the outer side of the limiting block 426. When the baffle fan 543 deflects, the rotating drum 422 deflects relative to the fixed block 421, which causes the torsion spring 423 to twist and store force. At the same time, the limiting block 426 slides along the surface of the annular guide rod 425 together with the rotating drum 422. When the limiting block 426 contacts the fixed plate 424, the fixed plate 424 will prevent the rotating drum 422 from continuing to rotate through the limiting block 426, thereby ensuring that the tilt angle of the baffle fan 543 and the agitator 546 is within a reasonable range. This can prevent excessive changes in the tilt angle of the baffle fan 543 and the agitator 546 due to excessive airflow or sudden changes in culture medium resistance, ensuring the stable operation of the stirring assembly 54 and the safety of the equipment.

[0044] The jet component 545 includes a jet pipe 451, a connecting bend 452 rotatably connected to the outer side of the jet pipe 451, an annular stop 454 fixedly connected to the inner wall of the jet pipe 451, a compression spring 455 fixedly connected to the inner side of the annular stop 454, an air guide tube 453 fixedly connected to the end of the compression spring 455 away from the annular stop 454, an exhaust pipe 459 fixedly connected to the outer side of the jet pipe 451, and an end of the connecting bend 452 away from the air guide tube 451 fixedly connected to the outer side of the air guide ring 541. The outer wall of the injection tube 451 is slidably connected to the inner wall of the air guide cylinder 453. The outer wall of the air guide cylinder 453 is slidably connected to the inner side of the annular stop block 454. An injection hole 450 is opened in the wall of the air guide cylinder 453. A connecting rod 456 is fixedly connected to the outer side of the air guide cylinder 453. A venting ring 457 is fixedly connected to the end of the connecting rod 456 away from the air guide cylinder 453. A spiral unblocking rod 458 is fixedly connected to the outer side of the venting ring 457. The outer wall of the spiral unblocking rod 458 is slidably connected to the inner wall of the exhaust pipe 459. The venting ring 457... The outer wall of the tube is slidably connected to the inner wall of the injection pipe 451. When the airflow enters the injection pipe 451 through the connecting bend 452, the airflow pushes the air guide cylinder 453 to slide along the inner side of the annular baffle 454, forcing the compression spring 455 to be compressed, thereby causing the injection hole 450 to protrude from the annular baffle 454. At this time, the airflow can be ejected outward through the injection hole 450. When no airflow passes through, the air guide cylinder 453 automatically resets under the elastic force of the compression spring 455, which can prevent the culture medium from flowing back through the injection hole 450. The pressure of the airflow affects the sliding degree of the air guide tube 453, which in turn allows the airflow to be ejected outward through more injection holes 450. This also allows for adjustment of the gas injection volume. When the airflow passes through the ventilation ring 457, as the inner diameter of the ventilation ring 457 gradually decreases, the decrease in the flow cross-sectional area leads to an increase in gas velocity. The accelerated airflow will enter the exhaust pipe 459 along the spiral unblocking rod 458 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 ones, increasing the specific surface area of ​​the bubbles and thus improving the dissolution efficiency of the gas in the culture medium. During this process, the high-speed airflow flows along the spiral unblocking 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 spray pipe 451, it drives the ventilation ring 457 to move synchronously through the connecting rod 456, which in turn causes the spiral unblocking rod 458 to 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 becoming blocked. When the airflow is ejected from the exhaust pipe 459, it can be sprayed onto the surface of the stirring paddle 546. When the airflow is sprayed onto the surface of the stirring paddle 546, 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 546.This has a certain self-cleaning effect, reducing the accumulation of dirt on the surface of the agitator 546, reducing the possibility of impurities affecting the performance of the agitator 546, and also helping to maintain the cleanliness of the culture environment.

[0045] Working principle:

[0046] In use, sterile agent is added to the culture tank 3 through the dosing cartridge 6 to provide a sterile environment for the cultivation of bio-based materials. Then, the culture medium of the bio-based materials is poured into the culture tank 3 by opening the cover plate 8. The electric heating platform 2 on the top of the base 1 can heat the culture tank 3 and adjust the culture medium to a suitable culture temperature.

[0047] Air compressor 4 starts, compresses air and outputs it to ventilation device 5. The compressed air is filtered by filter assembly 52 and then sent to stirring assembly 54. After passing through stirring assembly 54, it is sprayed into culture tank 3. At this time, under the reverse thrust of the airflow, stirring assembly 54 can drive air guide tube 51 to rotate, so that the culture medium is mixed evenly, promoting full contact between bio-based materials and nutrients and gases, which is beneficial to the growth and metabolism of bio-based materials. When the pressure inside culture tank 3 increases, the gas inside culture tank 3 can be discharged through exhaust valve 7. When culture tank 3 is not in use, the fluid inside culture tank 3 can be discharged through drain pipe 9.

[0048] When air enters the air guide pipe 51 through the filter assembly 52 and flows along the spiral air guide groove 53, the air, according to the principles of fluid mechanics, exerts a tangential force on the inner wall of the air guide pipe 51. This tangential force generates a torque, causing the air guide pipe 51 to tend to rotate around its axis. This torque, combined with the counter-thrust of the stirring assembly 54, drives the air guide pipe 51 to rotate, thus improving the energy efficiency of the equipment.

[0049] When the airflow enters the filter assembly 52, the air first passes through the protective shell 521 and enters the collection shell 523. The conical filter plate 522 can initially intercept larger impurities in the air. The impurities are trapped and rolled down the outer wall of the conical filter plate 522 into the collection shell 523 under the impact of the airflow. The guide plates 524 are inclined downward and staggered inside the collection shell 523. When the airflow passes through the guide plates 524, it will be continuously guided and blocked, and its flow velocity and direction will change multiple times, thereby weakening the upward force of the airflow on the impurities and effectively preventing the impurities from being backflushed.

[0050] The air guide hole 525 is located behind the guide plate 524. When impurities move towards the air guide hole 525 under the action of airflow, the speed and direction of the airflow change, making it difficult for impurities to obtain enough power to enter the air guide pipe 51 through the air guide hole 525. This further improves the interception efficiency of the filter assembly 52 for impurities. At the same time, the annular scraper 526 rotates together with the air guide pipe 51, which can push the impurities in the collection shell 523 to the side close to the cleaning plate 527. When the cleaning plate 527 is slid upward, the impurities inside the protective shell 521 can be cleaned out.

[0051] Air enters the air guide ring 541 through the air guide pipe 51 and is then ejected through the jet component 545. At this time, the thrust of the jet component 545 drives the entire stirring assembly 54 to rotate. As the turbulence fan 543 and the stirring paddle 546 rotate, they interact with the culture medium. By setting the torsion component 542, the turbulence fan 543 can adaptively adjust its deflection angle according to the change of the viscosity of the culture medium during rotation. In this process, the turbulence fan 543 forms a quadrilateral mechanism with the mounting frame 547 through the movable rod 544. When the turbulence fan 543 deflects, it will drive the mounting frame 547 to deflect synchronously with the jet component 545 as the base point through the movable rod 544. This causes the jet component 545 to drive the stirring paddle 546 to deflect synchronously, ensuring that the bio-based material can obtain good culture conditions under different viscosity environments.

[0052] Meanwhile, by setting up an arc-shaped baffle 548, when the arc-shaped baffle 548 rotates with the mounting frame 547, the arc-shaped baffle 548 can rotate relative to the mounting frame 547 under the push of the culture medium, changing the original movement trajectory of the culture medium, thereby forming complex eddies and turbulence in the culture medium, increasing the degree of fluid turbulence, which is conducive to the full contact between bio-based materials and nutrients and gases.

[0053] When the baffle fan 543 deflects, the rotating drum 422 deflects relative to the fixed block 421, causing the torsion spring 423 to twist and store force. Simultaneously, the limiting block 426 slides along the surface of the annular guide rod 425 along with the rotating drum 422. When the limiting block 426 contacts the fixed plate 424, the fixed plate 424 prevents the rotating drum 422 from continuing to rotate through the limiting block 426, thus ensuring that the tilt angles of the baffle fan 543 and the agitator 546 are within a reasonable range. This prevents excessive changes in the tilt angles of the baffle fan 543 and the agitator 546 due to excessive airflow or sudden changes in culture medium resistance, ensuring the stable operation of the stirring assembly 54 and the safety of the equipment.

[0054] When the airflow enters the jet pipe 451 through the connecting bend 452, the airflow pushes the air guide tube 453 to slide along the inner side of the annular block 454, forcing the compression spring 455 to be compressed, thereby causing the jet hole 450 to protrude from the annular block 454. At this time, the airflow can be ejected outward through the jet hole 450. When no airflow passes through, the air guide tube 453 automatically resets under the elastic force of the compression spring 455, which can prevent the culture medium from flowing back through the jet hole 450.

[0055] Simultaneously, the pressure of the airflow affects the sliding degree of the air guide tube 453, allowing the airflow to be ejected outward through more injection holes 450. This also allows for adjustment of the gas injection volume. When the airflow passes through the ventilation ring 457, as the inner diameter of the ventilation ring 457 gradually decreases, the reduced flow cross-sectional area leads to an increase in gas velocity. The accelerated airflow enters the exhaust pipe 459 along the spiral unblocking rod 458 and is finally ejected 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, increasing the specific surface area of ​​the bubbles, thereby improving the dissolution efficiency of the gas in the culture medium.

[0056] During this process, the high-speed airflow flows along the spiral unblocking 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 pipe 451, it drives the ventilation ring 457 to move synchronously through the connecting rod 456, which in turn causes the spiral unblocking rod 458 to 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 becoming blocked.

[0057] When the airflow exits from the exhaust pipe 459, it directly hits the surface of the agitator 546. The impact force of the airflow washes away impurities, bio-based materials, or metabolic products adhering to the surface of the agitator 546. This provides a degree of self-cleaning, reducing the accumulation of dirt on the surface of the agitator 546 and lowering the likelihood of impurities affecting its performance. It also helps maintain a clean culture environment.
