Description

Technical Field

[0001] This invention relates to the field of enzyme production technology, specifically to a quantitative stirring device for enzyme preparation production. Background Technology

[0002] Enzyme production involves adding raw materials to a stirring device and then synthesizing enzymes under biological action. After enzyme production, the inner wall of the stirring device needs to be thoroughly cleaned. Residual raw materials and enzymes inside the stirring device are prone to deterioration, and failure to clean them properly will contaminate the next enzyme production.

[0003] The shortcomings of existing stirring devices are: Existing technology CN223280830U discloses a stirring device for industrial enzyme preparation production. This technology discloses that the bottom of the tank is fitted with an outer channel steel for reinforcement, the top of the tank is sealed with a cover plate, and a feed pipe runs through the cover plate. A discharge pipe communicating with the interior of the tank is located on one side of the tank, and an observation window is opened on the side wall of the tank. This invention uses the output shaft of a motor to drive a conveying rod to rotate within the conveying pipe, which can transport the fermentation broth from the bottom of the tank to the top along the conveying pipe. This reduces the damage to enzyme protein molecules caused by shear force, and the broth flows outwards under the guidance of a guide plate and an arc-shaped groove, accelerating the circulation speed of the fermentation broth inside the tank. This ensures sufficient contact between cells and nutrients and guarantees a more uniform temperature distribution in the fermentation broth, avoiding localized overheating or undercooling, thereby improving cell growth rate and enzyme production efficiency.

[0004] The aforementioned technologies do not address the function of rapidly cleaning enzyme preparation stirring devices. Manual cleaning is slow, and rinsing with an external water flushing device results in incomplete cleaning. Therefore, a quantitative stirring device for enzyme preparation production is needed to solve this problem, which can clean the inner wall and bottom inner wall of the enzyme production device, avoid interfering with the discharge of enzyme preparations, and reduce the probability of enzyme preparation raw materials adhering to the inner wall of the device.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a scraper ring to scrape off the liquid adhering to the inner wall of the cylinder by moving downwards. At the same time, the stirring rod 2 moves downwards to contact the inner wall of the bottom of the cylinder. Then, the rotating stirring rod 2 and the movable tube scrape off the liquid from the inner wall of the bottom of the cylinder.

[0025] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides a quantitative stirring device for enzyme preparation production, comprising a cylinder 1, a controller 3 mounted on the front of the cylinder 1, hydraulic cylinders 7 symmetrically mounted on both sides of the cylinder 1, and the hydraulic cylinders 7 electrically connected to the controller 3, a cover plate 8 mounted on the output end of the hydraulic cylinders 7, a sealing gasket 9 mounted on the bottom of the cover plate 8, a frame 16 mounted on the top of the cover plate 8, a hydraulic cylinder 17 mounted on the top of the frame 16, and the hydraulic cylinder 17 electrically connected to the controller 3, a piston rod 18 mounted on the output end of the hydraulic cylinder 17, one end of the piston rod 18 penetrating the bottom of the cover plate 8, a lifting plate 19 mounted on one end of the piston rod 18, a motor 20 mounted on the bottom of the lifting plate 19, and the motor 20 electrically connected to the controller 3; Furthermore, the cylinder 1 provides production space for enzyme preparations and also provides installation positions for other components of the equipment. The hydraulic cylinder 7 is controlled by the controller 3. The hydraulic cylinder 7 drives the cover plate 8 to move up and down. When the cover plate 8 moves upward, it is convenient for personnel to clean the inside of the cylinder 1. The cover plate 8 is made of transparent material, which makes it easy for people to observe the inside of the cylinder 1. When the cover plate 8 moves downward, it seals the top of the cylinder 1 to prevent external pollutants from entering the inside of the cylinder 1 and contaminating the production raw materials inside the cylinder 1. The sealing gasket 9 plays a sealing role and seals the gap between the cylinder 1 and the cover plate 8. Furthermore, the frame 16 provides an installation position for the second hydraulic cylinder 17. The second hydraulic cylinder 17 is controlled by the controller 3. The operation of the second hydraulic cylinder 17 drives the first piston rod 18 to move up and down. The up and down movement of the first piston rod 18 drives the lifting plate 19 to move up and down, which in turn drives the motor 20, the rotating rod 21, the first stirring rod 22, and the second stirring rod 23 to move up and down. This allows the first stirring rod 22 and the second stirring rod 23 to stir the raw materials inside the cylinder 1 while moving up and down, reducing the stirring dead zone, improving the contact efficiency between the organism and the raw materials inside the cylinder 1, and thus improving the efficiency of the biosynthetic enzyme preparation.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5An embodiment of the present invention provides a quantitative stirring device for enzyme preparation production. A rotating rod 21 is installed at the output end of a motor 20. Multiple stirring rods 22 are symmetrically installed on both sides of the rotating rod 21. A scraping mechanism is symmetrically arranged on the outer side of the rotating rod 21. The scraping mechanism includes a second stirring rod 23, a movable tube 24, a sealing ring 25, and a spring 26. Two second stirring rods 23 are symmetrically installed on both sides of the rotating rod 21. A movable tube 24 is movably installed on the outer side of the second stirring rod 23. A sealing ring 25 is installed on the inner wall of the movable tube 24. A spring 26 is installed on one side of the inner wall of the movable tube 24, and one end of the spring 26 is connected to one end of the second stirring rod 23. Furthermore, the operation of motor 20 drives the rotating rod 21 to rotate, and the rotation of rotating rod 21 drives the stirring rod 22 and stirring rod 23 to rotate, thereby making the stirring rod 22 and stirring rod 23 stir the liquid inside the cylinder 1, so that the contact between the organisms in the liquid and the raw materials and oxygen is more sufficient, and the efficiency of biosynthetic enzyme preparation is improved. Furthermore, when the stirring rod 23 and the movable tube 24 descend to their lowest point, they can simultaneously contact the inner wall of the bottom of the cylinder 1. Under the elastic pressure of the spring 26, the movable tube 24 can move outwards to contact the inner wall of the cylinder 1. This allows the rotating stirring rod 23 to scrape away the material on the inner wall of the bottom of the cylinder 1, avoiding the situation where the stirring rod 23 is not long enough to scrape a wider area of ​​the inner wall of the bottom of the cylinder 1. This prevents material from adhering to the inner wall of the bottom of the cylinder 1 and affecting the utilization of the material by the organism, thus improving the utilization rate of raw materials. The movable tube 24 can also move left and right outside the stirring rod 23. This allows the movable tube 24 to move up and down with the rotating rod 21. When the movable tube 24 encounters the scraper ring 29, it can be squeezed by the oblique side of the scraper ring 29, which has a greater outer thickness than the inner thickness. This causes the movable tube 24 to be squeezed and move towards the rotating rod 21. As a result, the scraper ring 29 can move up and down by squeezing the movable tube 24 inward, thus avoiding interference between the movable tube 24 and the scraper ring 29 during its up and down movement. Furthermore, when the scraper ring 29 and the movable tube 24 are no longer in contact, the spring 26 squeezes the movable tube 24, causing it to be squeezed outward and contact the inner wall of the cylinder 1.

[0027] Please see Figure 1 and Figure 2 An embodiment of the present invention provides a quantitative stirring device for enzyme preparation production. Support columns 2 are symmetrically installed at the bottom of the cylinder 1. An air inlet pipe 4 is installed at the input end on the right side of the cylinder 1. A discharge pipe 5 is installed at the output end on the front side of the cylinder 1. A solenoid valve 6 is installed at the output end of the discharge pipe 5 and is electrically connected to the controller 3. An exhaust pipe 34 is installed at the output end of the cover plate 8. A solenoid valve 35 is installed at the output end of the exhaust pipe 34 and is electrically connected to the controller 3. Furthermore, the support column 2 provides support for the cylinder 1, the input end of the air inlet pipe 4 is connected to an external air filtration and sterilization device, providing an entry path for sterilized air from the outside to enter the cylinder 1, the discharge pipe 5 provides an discharge path for the enzyme preparation products inside the cylinder 1 to be discharged, the solenoid valve 6 controls the opening and closing of the discharge pipe 5, so that the process of material discharge from the cylinder 1 through the discharge pipe 5 can be controlled, the exhaust pipe 34 provides an exhaust path for the air inside the cylinder 1 to be discharged, and the solenoid valve 35 controls the opening and closing of the exhaust pipe 34, controlling the process of gas inside the cylinder 1 being discharged through the exhaust pipe 34; Furthermore, sterilized air from the outside enters the cylinder 1 through the air inlet pipe 4 to supply oxygen to the microorganisms inside the cylinder 1, providing the necessary conditions for the microorganisms to produce enzymes. Then, the controller 3 controls the solenoid valve 35 to open, so that the gas inside the cylinder 1 is discharged through the exhaust pipe 34, thereby maintaining the stability of the air pressure inside the cylinder 1.

[0028] Please see Figure 1 and Figure 2 An embodiment of the present invention provides a quantitative stirring device for enzyme preparation production, wherein a water inlet pipe 36 is installed at the top input end of the cover plate 8, and a solenoid valve 37 is installed at the input end of the water inlet pipe 36, and the solenoid valve 37 is electrically connected to the controller 3. Furthermore, the water inlet pipe 36 provides an entry path for sterilized water from the outside to enter the interior of the cylinder 1, and the solenoid valve 37 controls the opening and closing of the water inlet pipe 36.

[0029] Please see Figure 1 and Figure 2 An embodiment of the present invention provides a quantitative stirring device for enzyme preparation production. A plate body 10 is installed on the back of a cover plate 8, and a plurality of storage boxes 11 are installed on the top of the plate body 10. A timer 12 is installed on the front of the storage box 11 and is electrically connected to a controller 3. An infusion tube 13 is installed at the output end of the front of the storage box 11. A flow valve 14 is installed at the output end of the infusion tube 13 and is electrically connected to the controller 3. An infusion tube 2 15 is installed at the output end of the flow valve 14 and the output end of the infusion tube 2 15 penetrates the bottom of the cover plate 8. Furthermore, plate 10 provides an installation position for storage box 11, which serves to store liquid raw materials to provide necessary raw materials for microbial enzyme synthesis. Timer 12 keeps track of the time. After flow valve 14 is opened, the raw materials inside storage box 11 enter flow valve 14 through infusion pipe 13, then enter infusion pipe 2 15 through flow valve 14, and are discharged through infusion pipe 2 15 into cylinder 1 to provide necessary raw materials for microorganisms inside cylinder 1. Timer 12 keeps track of the opening time of flow valve 14. The flow rate of flow valve 14 and the timing time of timer 12 facilitate controller 3 to calculate the amount of raw materials injected into cylinder 1, thereby achieving effective control of the amount of material added into cylinder 1.

[0030] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 An embodiment of the present invention provides a quantitative stirring device for enzyme preparation production, wherein cylinder 27 is symmetrically installed on the top of cover plate 8 and cylinder 27 is electrically connected to controller 3, piston rod 28 is installed at the output end of cylinder 27, and one end of piston rod 28 penetrates the bottom of cover plate 8, and scraper ring 29 is installed at one end of piston rod 28. Furthermore, controller 3 controls cylinder 27 to operate, converting pneumatic energy into kinetic energy, which in turn drives piston rod 28 to move up and down. The up-and-down movement of piston rod 28 drives scraper ring 29 to move up and down. Scraper ring 29 is a symmetrical ring structure with an outer thickness greater than the inner thickness, and both sides of scraper ring 29 are inwardly concave slopes. When movable tube 24 contacts the slope of scraper ring 29, it can be squeezed towards rotating rod 21, thus facilitating scraper ring 29 to pass over movable tube 24 during its up-and-down movement. When moving, it can scrape off the raw materials and products adhering to the inner wall of the cylinder 1. On the other hand, during the biosynthesis of enzymes inside the cylinder 1, it can tumble the liquid on the periphery of the liquid inside the cylinder 1, accelerate the flow of the liquid, and make it easier for the liquid on the periphery to flow to the inner periphery. This makes it easier for the centrifuged raw materials on the periphery to flow to the inner periphery, increasing the balance of materials in the liquid. It avoids the situation where the material is too concentrated and the efficiency of enzyme synthesis is reduced due to the centrifugation of large objects in the liquid by the stirring rod 22.

[0031] Please see Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 An embodiment of the present invention provides a quantitative stirring device for enzyme preparation production. A second cylinder 30 is symmetrically installed on the top of the cover plate 8, and the second cylinder 30 is electrically connected to the controller 3. A third piston rod 31 is installed at the output end of the second cylinder 30, and one end of the third piston rod 31 penetrates the bottom of the cover plate 8. A semi-circular rod 32 is installed at one end of the third piston rod 31. A brush 33 is installed on the outside of the semi-circular rod 32, and the semi-circular rod 32 is located inside the scraper ring 29. Furthermore, the controller 3 controls the operation of cylinder 2 30. The operation of cylinder 2 30 drives piston rod 31 to move up and down. The up and down movement of piston rod 31 drives semi-circular rod 32 to move up and down. The up and down movement of semi-circular rod 32 drives scraper brush 33 to move up and down. When brush 33 moves up and down, it can clean the inner side of scraper ring 29 and the outer side of stirring rod 1 22 and stirring rod 23, reducing the adhering material. Before semi-circular rod 32 moves down, it is necessary to observe through the transparent cylinder 1 whether stirring rod 1 22 has rotated into the plane formed by left and right, so that semi-circular rod 32 can move up and down smoothly and avoid the situation where semi-circular rod 32 is interfered with by stirring rod 1 22 when it moves down.

[0032] Working Principle: Before using the quantitative stirring device for enzyme preparation production, it should be checked whether there are any problems affecting its use. The cover plate 8 is lowered, and then sterile water is added to the inside of the cylinder 1 through the water inlet pipe 36. Then, the raw materials in the storage box 11 are injected into the inside of the cylinder 1. Subsequently, sterile air is supplied to the liquid inside the cylinder 1 through the air inlet pipe 4. Then, the motor 20 drives the stirring rods 22 and 23 to rotate and stir the liquid, making the materials in the liquid uniform. At the same time, the hydraulic cylinder 17 drives the stirring rods 22 and 23 to move up and down, reducing the dead zones in the stirring of the liquid inside the cylinder 1. The scraper ring 29 also moves up and down, squeezing the liquid towards the inner periphery, increasing the uniformity of the materials in the liquid, and avoiding excessive concentration of materials caused by the centrifugal movement of large objects in the liquid due to the stirring of the stirring rod 22. When the enzyme efficiency decreases, after a certain period of time, the enzyme preparation is completed and discharged through the discharge pipe 5. Then, water is added to the inside of the cylinder 1. The scraper ring 29 moves downward to scrape off the liquid adhering to the inner wall of the cylinder 1. At the same time, the stirring rod 23 moves downward to contact the bottom inner wall of the cylinder 1. Then, the rotating stirring rod 23 and the movable tube 24 scrape off the liquid from the bottom inner wall of the cylinder 1. Then, the stirring rod 23 moves upward to make it easier for the liquid to be discharged from the discharge pipe 5, avoiding interference from the stirring rod 23 at the bottom and making the liquid discharge more thorough. Next, the stirring rod 22 is rotated into the plane formed by left and right. When the brush 33 moves up and down, it cleans the inner side of the scraper ring 29 and the outer side of the stirring rod 22 and the stirring rod 23 to reduce the adhering material. When the movable tube 24 contacts the inclined surface of the scraper ring 29, it can be squeezed towards the direction of the rotating rod 21, so that the scraper ring 29 can pass over the movable tube 24 when it moves up and down.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
