The adjusting motor 502 drives the main gear 503 to rotate, and drives the sub-gear 501 to rotate through the chain 504, thereby realizing the rotation of the sterile culture tank 1.

[0032] A defoaming assembly 3 is provided in the middle of the cover body 101, and the defoaming assembly 3 includes a telescopic shaft 301 and a frame seat 308. The fixed end of the telescopic shaft 301 is rotatably connected to the middle of the cover body 101. The movement between the telescopic end and the fixed end of the telescopic shaft 301 can only be telescopic and sliding but cannot rotate relatively. A mounting seat 302 is provided at the bottom telescopic end of the telescopic shaft 301. The circumferential surface of the mounting seat 302 is provided with inclined plates 303 in a ring array. The telescopic end surface of the inclined plate 303 is evenly provided with a shift block 304. The bottom end of the shift block 304 extends out of the surface of the inclined plate 303. A driving motor 307 is provided at the top of the cover body 101 through the machine base. The output shaft of the driving motor 307 is fixedly connected to the top fixed end of the telescopic shaft 301. The driving motor 307 drives the telescopic shaft 301 to rotate. The telescopic shaft 301 drives each inclined plate 303 to rotate through the mounting seat 302, thereby realizing the rotation of the shift block 304. When the shift block 304 rotates, the bubbles generated on the top of the liquid bacteria are broken.

[0033] The top surface of the mounting seat 302 is rotatably connected with a rotating ring 305, and the top of the rotating ring 305 is provided with an electric telescopic part 306, and the fixed end of the electric telescopic part 306 is fixedly connected to the cover body 101, and the rotating ring 305 is sleeved on the outside of the telescopic shaft 301. The telescopic movement of the electric telescopic part 306 drives the rotating ring 305 to move up and down, and the rotating ring 305 drives the mounting seat 302 to move up and down, thereby realizing the up and down movement of the tilting plate 303 and the shifting block 304, and the height of the shifting block 304 can be adjusted according to the liquid level of the liquid culture, and the lowest position that the shifting block 304 can be adjusted is always located above the stirring assembly 4.

[0034] The frame seat 308 is arranged in a circular array on the top side of the inner wall of the sterile culture tank 1, and a movable seat 309 is slidably connected inside the frame seat 308. A locking mechanism for positioning the movable seat 309 is provided on the movable seat 309. A limiting elastic member 310 is provided between the end of the movable seat 309 away from the inclined plate 303 and the inner wall of the frame seat 308. The locking mechanism is preferably an electromagnetic latch. In the initial state, the pin rod of the locking mechanism is extended to contact the inner wall of the frame seat 308 to position the movable seat 309, and the movable seat 309 cannot slide. At this time, the movable seat 309 is located in the frame seat 308, close to one end of the inner wall of the sterile culture tank 1, the limiting elastic member 310 is in a compressed state, and the wedge block 311 does not contact the inclined plate 303 in the rotating state.

[0035] A wedge block 311 is horizontally provided on the top of the movable seat 309, and the inclined surface of the wedge block 311 corresponds to the end of the inclined plate 303. In the initial state, the end of the inclined plate 303 corresponds to the inclined surface of the wedge block 311 and does not contact. When the locking mechanism releases the lock on the movable seat 309, the end of the inclined plate 303 squeezes the inclined surface of the wedge block 311 during the rotation of the inclined plate 303, so that the inclined plate 303 elastically contracts, and the shift block 304 on the telescopic end of the inclined plate 303 moves radially. After the end of the inclined plate 303 completely passes through the inclined surface of the wedge block 311, the compressed inclined plate 303 is reset.

[0036] A stirring assembly 4 is provided at the bottom of the defoaming assembly 3, and the stirring assembly 4 includes a hollow shaft 401, which is provided below the mounting seat 302, and an electromagnetic clutch is provided between the top of the hollow shaft 401 and the mounting seat 302, and the ends of the hollow shaft 401 and the mounting seat 302 are respectively fixedly connected to the two transmission ends of the electromagnetic clutch, and elastic telescopic parts 403 are provided at equal intervals on the side of the hollow shaft 401 from top to bottom, and a connecting rod 405 is provided between the telescopic ends of the upper and lower elastic telescopic parts 403, and the electromagnetic clutch is used to control the connection and disconnection between the mounting seat 302 and the hollow shaft 401. When the mounting seat 302 and the hollow shaft 401 are connected as a whole, the rotation of the mounting seat 302 drives the hollow shaft 401 to rotate slowly, so that the elastic telescopic part 403 rotates to slowly stir the liquid bacteria.

[0037] The elastic expansion member 403 is a hollow structure. The structure of the elastic expansion member 403 is as follows: Figure 6 As shown, the elastic telescopic member 403 is composed of two hollow plates which are socketed with each other, and an elastic member is arranged in the hollow plate located on the outside, the elastic telescopic member 403 is interconnected with the hollow shaft 401, and air holes 404 are opened on the sides of the elastic telescopic member 403, and the bottom end of the hollow shaft 401 is rotatably connected with an air inlet pipe 402, the air inlet pipe 402 passes through the bottom end of the sterile culture tank 1 and is fixedly connected with the output end of the external air supply system, and the external air supply system is connected with the air inlet pipe 402 to realize the introduction of sterile air into the air inlet pipe 402, the sterile air enters each elastic telescopic member 403 through the hollow shaft 401, and is finally discharged into the liquid bacteria through the air holes 404 on the elastic telescopic member 403, so as to provide sterile oxygen for the liquid bacteria.

[0038] When in use, the sterile culture tank 1 is adjusted to a vertical state, the sealing cover 103 is opened, and the liquid bacteria to be cultured is injected into the sterile culture tank 1 from the feed hopper 102. While injecting, the drive motor 307 is started to drive the telescopic shaft 301 to rotate slowly. The telescopic shaft 301 drives the inclined plate 303 to rotate slowly through the mounting seat 302. The rotation and inclination angle of the inclined plate 303 are used to move the liquid bacteria to be cultured so that the liquid bacteria to be cultured are evenly dispersed. At this time, the end of the inclined plate 303 does not contact the wedge block 311. At the same time, the electromagnetic clutch is started to connect the top of the hollow shaft 401 with the bottom of the mounting seat 302. The elastic telescopic part 403 can be driven to rotate through the connection between the hollow shaft 401 and the mounting seat 302 while the inclined plate 303 rotates, so that the liquid bacteria to be cultured are evenly distributed in the sterile culture tank 1 after the bacteria to be cultured fall into the sterile culture tank 1. After the liquid bacteria are injected, the sealing cover 103 is used to seal the feed hopper 102.

[0039] When it is necessary to supply oxygen to the liquid bacteria being cultured, sterile air is introduced into the air inlet pipe 402 using an external air supply system. The sterile air enters the hollow shaft 401 and then the elastic telescopic part 403, and is discharged into the liquid bacteria through the air hole 404 to achieve oxygen supply. While supplying oxygen, the electromagnetic clutch connects the hollow shaft 401 and the mounting seat 302 as a whole, and starts the drive motor 307 to achieve synchronous rotation of the inclined plate 303 and the elastic telescopic part 403. The rotation of the elastic telescopic part 403 drives the connecting rod 405 to rotate, so that the sterile air introduced is fully and evenly integrated with the liquid bacteria.

[0040] However, during the oxygen supply process, more bubbles will be generated on the top of the liquid culture, which will affect the culture effect of the liquid culture. Therefore, the following improvements are made:

[0041] While supplying oxygen, the electric telescopic part 306 is extended and retracted to drive the mounting seat 302 to rise and fall through the rotating ring 305, and the height of the inclined plate 303 is adjusted so that the bottom of the shift block 304 is infinitely close to the liquid level of the liquid bacteria. The liquid level position of the liquid bacteria is determined by a liquid level meter, and then when the inclined plate 303 and the elastic telescopic part 403 rotate synchronously, the end of the shift block 304 is used to break the bubbles on the top of the liquid bacteria to eliminate the bubbles.

[0042] However, during oxygen supply, when the inclined plate 303 and the elastic member 403 rotate synchronously, when the elastic member 403 is rotated to fully fuse the sterile air with the liquid bacteria, there are blind spots between the elastic members 403, and the sterile air is still evenly and fully fused with the liquid bacteria. When the dial block 304 is rotated to eliminate bubbles, only bubbles in a fixed area can be eliminated, resulting in incomplete bubble elimination. In order to solve the above problems:

[0043] The inclined plate 303 is an elastic telescopic structure. Figure 7 As shown, it is composed of a movable plate and a fixed frame sleeved on the outside of the movable plate, and an elastic part is provided between the movable plate and the fixed frame.

[0044] During the process of introducing sterile air and when the inclined plate 303 and the elastic telescopic member 403 rotate synchronously, the locking mechanism releases the lock on the movable seat 309, so that the limiting elastic member 310 extends and releases to drive the movable seat 309 to move toward the center of the sterile culture tank 1 to the other end of the frame seat 308, and then the locking mechanism is used to lock and fix the movable seat 309. At this time, during the rotation of the inclined plate 303, the end of the inclined plate 303 conflicts with the wedge surface of the wedge block 311, and the inclined plate 303 is elastically squeezed to realize the horizontal movement of the shift block 304. When the inclined plate 303 completely passes through the wedge block 311, the elastic telescopic member 403 is reset to its initial length, so that when the inclined plate 303 rotates, the horizontal reciprocating motion of the shift block 304 is realized by cooperating with the annularly arranged wedge blocks 311, thereby expanding the bubble breaking area and improving the defoaming effect.

[0045] After the above operation is run for a specified time, the electric telescopic part 306 is started to drive the mounting seat 302 and the inclined plate 303 to move upward through the rotating ring 305, the telescopic shaft 301 contracts, and the elastic telescopic member 403 moves upward, so that the end of the elastic telescopic member 403 located at the top corresponds to the wedge surface of the wedge block 311. At this time, when the elastic telescopic member 403 is rotated to correspond to the wedge block 311, the elastic telescopic member 403 is squeezed by the wedge surface of the wedge block 311, and the elastic telescopic member 403 at the top contracts, so that the connecting rod 405 drives the other elastic telescopic members 403 at the bottom to contract synchronously, and the connecting rod 405 moves toward the center of the sterile culture tank 1. When the elastic telescopic member 403 completely passes through the wedge block 311, the elastic telescopic member 403 is telescoped. The end is extended and reset, and the connecting rod 405 is reset, so that the horizontal reciprocating motion of the connecting rod 405 is realized when the elastic telescopic part 403 rotates, and the elastic telescopic parts 403 and the connecting rod 405 at the bottom are driven to reciprocate horizontally, so as to realize stirring of the area between the elastic telescopic parts 403, so that the sterile air and the liquid bacteria are fully integrated, and the intermittent expansion and contraction of the electric telescopic part 306 is utilized to make the ends of the inclined plate 303 and the elastic telescopic part 403 correspond to the wedge block 311 in turn, thereby improving the defoaming efficiency and realizing the full integration of the sterile air and the liquid bacteria. That is, the present invention improves the defoaming effect and the uniformity of mixing of the sterile air and the liquid bacteria by utilizing the linkage cooperation between the defoaming component 3 and the stirring component 4.

[0046] In addition, during the liquid bacterial culture process, some bacterial strains will adhere to the inner wall of the sterile culture tank 1, resulting in some bacterial strains being unable to be cultured normally, and it is difficult to clean the inner wall after the culture is completed, so the following improvements are made:

[0047] The bottom of the movable seat 309 is rotatably connected to a mounting rod 312, and a torsion spring is sleeved on the top of the mounting rod 312. The two ends of the torsion spring are respectively fixedly connected to the bottom of the movable seat 309 and the side of the mounting rod 312. A paddle plate 313 is provided on the side of the mounting rod 312 close to the inner wall of the sterile culture tank 1. The side of the paddle plate 313 is in contact with the inner wall of the sterile culture tank 1. In the initial state, there is an angle between the paddle plate 313 and the inner wall of the sterile culture tank 1.

[0048] When in use, during the cultivation of liquid bacteria, it is necessary to regularly clean the inner wall of the sterile culture tank 1. During cleaning, the end of the inclined plate 303 is matched with the wedge surface of the wedge block 311, and the drive motor 307 is started to rotate the inclined plate 303. During this process, the electromagnetic clutch is used to disconnect the connection between the hollow shaft 401 and the mounting seat 302, and the locking mechanism releases the fixation of the movable seat 309, so that the movable seat 309 is located in the frame seat 308 at one end away from the inner wall of the sterile culture tank 1 and can slide freely. While the inclined plate 303 rotates, the wedge block 311 is squeezed so that the wedge block 311 drives the movable seat 309 to move horizontally toward the inner wall of the sterile culture tank 1, and the mounting rod 312 moves toward the inner wall of the sterile culture tank 1. At this time, the dial plate 313 is moved by the sterile culture The inner wall of the culture tank 1 is squeezed, so that the side of the paddle plate 313 moves along the inner wall of the sterile culture tank 1. At the same time, the mounting rod 312 is rotated, the torsion spring is twisted, and when the paddle plate 313 is squeezed and tilted to the maximum angle, the side of the paddle plate 313 that is in contact with the inner wall of the tank body 1 just moves to the initial position where the adjacent paddle plate 313 is in contact with the inner wall of the tank body 1, thereby realizing the paddle plate 313 to scrape off the bacteria attached to the inner wall of the sterile culture tank 1. After the horizontal squeezing force on the inclined surface of the wedge block 311 disappears, the squeezed limiting elastic member 310 is quickly reset, and the paddle plate 313 is restored to the initial position as the torsion spring is reset, thereby realizing the cleaning of the bacteria attached to the inner wall of the sterile culture tank 1, allowing more bacteria to be cultured normally, improving the utilization rate of the bacteria, and facilitating the cleaning of the inner wall of the sterile culture tank 1 in the later stage.

[0049] After the cultivation is completed, the control valve is opened to open the discharge pipe 104, and the regulating motor 502 is started to drive the main gear 503 to rotate. The main gear 503 drives the sub-gear 501 to rotate through the chain 504, so that the aseptic culture tank 1 is flipped at an angle greater than 90 degrees, so that the liquid bacteria cultured in the aseptic culture tank 1 are discharged into the external container through the discharge pipe 104, and a sterile environment is ensured during the discharge process.

[0050] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
