Description

Technical Field

[0001] The present invention relates to the technical field of bio-agricultural equipment, and specifically to a fermentation auxiliary device for intelligently judging the spore rate of fermentation broth. Background Art

[0002] In the field of bio-agriculture, fermenters, as important auxiliary equipment in the microbial fermentation process, are widely used. Their main function is to provide a precisely controlled environment to promote the growth and metabolism of microorganisms, thereby completing specific fermentation reactions. In the traditional fermentation process, the growth status of the microbial flora in the fermentation broth directly affects the quality and yield of the final product.

[0003] Currently, most fermenters on the market use traditional stirring forms to stir the fermentation broth. Although such a stirring method can achieve a stirring effect, it cannot be adaptively adjusted according to the requirements of different fermentation stages. Moreover, when sampling the fermentation broth with a traditional fermenter, it is necessary to open a hole in the tank body and install a corresponding sampling device. Such a method has a low level of integration and does not conform to the concept of today's intelligent production. In addition, it is difficult to avoid the generation of foam at the top of the fermentation broth during fermentation. Since the liquid level of the fermentation broth is different during each reaction, it is necessary to adjust the position of the defoaming device, and it is impossible to automatically follow the liquid level to adjust the position, resulting in a low fermentation efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a fermentation auxiliary device for intelligently judging the spore rate of fermentation broth to solve the problems raised in the prior art.

[0006] The fermentation auxiliary device is externally connected to a control cabinet, and a control system is installed inside the control cabinet. The control system is used to control the entire fermentation auxiliary device. There is a feed port on the end cover for pouring in the fermentation broth. The fermentation tank is designed with a hollow part, and a heating chamber is provided in the hollow part. The heating chamber is provided with a water inlet and a water outlet, and the water inlet and the water outlet are used for injecting or discharging the heating medium. The temperature of the fermentation broth in the fermentation tank is controlled by the heating medium; the water pump and the rotating shaft are internally connected through a rigid pipe fitting. When the water pump rotates, the rotating shaft is synchronously driven to rotate through the rigid pipe fitting. The water pump is externally connected with an intelligent detection device, which is used to detect the spore rate of the fermentation broth. After the detection is completed, the fermentation broth is reversely conveyed back into the fermentation tank through the water pump.

[0007] Further, the defoamer includes a guide pipe, the rotating shaft penetrates through the guide pipe, and a number of guide grooves are provided on the guide pipe. The guide pipe is installed at the bottom end of the end cover, and a floating component is slidably installed on the guide pipe, and a defoaming component is slidably installed on the floating component.

[0008] Further, a vertical flow channel is provided inside the rotating shaft. The rotating shaft is communicated with the water pump through the vertical flow channel. A number of side holes are provided on the rotating shaft, and the side holes are communicated with the vertical flow channel. The rotating shaft is internally communicated with the stirring component through the side holes. A strip-shaped vertical groove is provided on the rotating shaft, and the defoaming component passes through the guide groove and is fitted with the strip-shaped vertical groove.

[0009] Further, the defoaming component includes a vibrating rod. A ball is rotatably installed at one end of the vibrating rod. A number of thorns are installed on the vibrating rod. A vibrating spring is installed between the vibrating rod and the floating component. The vibrating rod is slidably installed inside the floating component. The vibrating rod is slidably connected with the guide groove, and the ball is slidably connected with the strip-shaped vertical groove.

[0010] The ball is fitted in the strip-shaped chute and can slide up and down along the strip-shaped vertical groove.

[0011] Further, the floating component includes a connecting ring, the connecting ring is slidably installed on the guide pipe, a number of sliding pipes are installed on the connecting ring, a floating plate is installed at the bottom end of the sliding pipe, the vibrating rod is slidably installed inside the sliding pipe, a vibrating spring is installed between the vibrating rod and the sliding pipe, the vibrating rod penetrates through the connecting ring, and the floating plate and the sliding pipe are made of lightweight materials.

[0012] The floating plate can drive the entire defoamer to float on the top of the fermentation broth.

[0013] The staff adds the fermentation broth into the fermenter through the feed port on the end cover. Since the floating plate and the sliding tube are made of lightweight materials, the floating plate drives the entire defoamer to float to the top of the fermentation broth. The control system turns on the drive motor, and the drive motor drives the water pump to rotate through the connecting piece. The water pump drives the rotating shaft to rotate through the rigid pipe fitting. When the rotating shaft rotates, the strip-shaped vertical groove deviates from its original position, squeezing out the ball originally fitted in the strip-shaped vertical groove. The ball drives the vibrating rod to slide and compress the vibrating spring. When the next strip-shaped vertical groove rotates to the position of the ball, the compressed vibrating spring drives the vibrating rod to rebound, and the ball is fitted into the strip-shaped vertical groove again. This cycle makes the vibrating rod produce a reciprocating vibration effect, and the vibrating rod drives the thorn needle to reciprocate, thereby removing the foam generated at the top of the fermentation broth.

[0014] Further, the stirring assembly includes a fixed ring provided with a diversion hole communicating with the side hole. A stirring rod is installed on the fixed ring, and a stirring blade is rotatably installed on the stirring rod. A sampling assembly is slidably installed in the stirring rod. The sampling assembly communicates with the fixed ring through the diversion hole. The stirring blade is meshed and driven with the sampling assembly, and a return spring is installed between the sampling assembly and the fixed ring.

[0015] When the rotating shaft rotates, it drives the stirring assembly to rotate. The blades on the stirring rod agitate the fermentation broth, making the fermentation broth fully mixed to achieve the effect of primary stirring. The control system changes the rotation speed of the drive motor according to the fermentation condition. When it is necessary to improve the fermentation quality or efficiency, the control system increases the motor speed, so that the rotating shaft drives the stirring assembly to rotate rapidly. The rotation generates centrifugal force. When the centrifugal force reaches the preset value, the gravity end drives the diversion pipe to overcome the elastic force of the return spring and slide along the transmission pipe. The return spring stretches. The diversion pipe drives the sliding strip to slide, and the sliding strip drives the stirring blade to deflect through the tooth groove. The stirring blade unfolds, and the stirring area of the stirring assembly for the fermentation broth increases, strengthening the stirring of the fermentation broth to achieve the purpose of secondary stirring. The faster the rotation speed of the rotating shaft, the greater the centrifugal force of the stirring assembly, the greater the sliding distance of the gravity end driving the diversion pipe, the greater the unfolding amplitude of the stirring blade, and the stronger the stirring effect on the fermentation broth. By controlling the centrifugal force, the control of the secondary stirring effect is realized; When the stirring blade is fully unfolded, the gravity end drives the diversion pipe to extend to the maximum distance. At this time, the position where the gravity end is located can reach the anti-blocking vibration assembly. The gravity end and the convex block produce extrusion, and the gravity end is compressed and retracted, so as to slide over the convex block. When the gravity end slides over, the filter screen on it generates friction with the flexible brush plate on the convex block, and the flexible brush plate cleans the filter screen to prevent the filter screen from being blocked, thus affecting the sampling of the fermentation broth; during the retraction process of the gravity end, the stirring blade is synchronously retracted. After the gravity end bypasses the convex block, it drives the stirring blade to unfold again under the action of centrifugal force. This reciprocation makes the stirring blade unfold and retract reciprocally, forming a swing, further strengthening the disturbance of the fermentation broth, achieving the purpose of tertiary stirring, and finally making the fermentation broth evenly mixed under the action of multi-stage stirring, and the fermentation quality and efficiency are improved.

[0016] Furthermore, the stirring rod includes a transmission pipe, on which blades are installed. A number of connecting columns are installed on the blades, and stirring vanes are rotatably installed on the connecting columns. A chute is provided between the blade and the transmission pipe, and the sampling assembly is slidably installed in the transmission pipe.

[0017] Furthermore, the sampling assembly includes a diversion pipe, at one end of which a corrugated pipe is installed, and at the other end a gravity end is installed. Sampling holes are provided on the gravity end, and the gravity end communicates with the diversion pipe through the sampling holes. The diversion pipe communicates with the corrugated pipe, and the corrugated pipe communicates with the diversion holes. A filter screen is installed on the gravity end, and a sliding strip is installed on the diversion pipe. The diversion pipe is slidably connected to the transmission pipe, and the sliding strip is slidably installed in the chute. A return spring is installed between the diversion pipe and the fixed ring, and the sliding strip is in meshing transmission with the stirring vane.

[0018] The gravity end is made of a high-density anti-friction material.

[0019] The control system intermittently turns on the water pump, and the water pump generates suction force on the rotating shaft and the stirring assembly. The fermentation broth is filtered through the filter screen and flows into the diversion pipe from the sampling holes, then through the corrugated pipe, and then is successively transported to the intelligent detection device through the diversion holes, side holes, and vertical flow channels by the water pump. The intelligent detection device detects the spore rate of the fermentation broth, achieving the purpose of automatic sampling and intelligent detection of the spore rate. After the detection is completed, the fermentation broth is reversely transported back into the fermentation tank by the water pump, achieving the purpose of fermentation broth reflux and avoiding waste of the fermentation broth.

[0020] Furthermore, a number of tooth grooves are provided on the sliding strip, and rotating teeth are provided on the stirring vane. The rotating teeth are in meshing transmission with the tooth grooves.

[0021] Furthermore, the anti-blocking vibration assembly includes a convex block, on which a flexible brush plate is installed. The convex block is installed in the fermentation tank.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The rotating shaft drives the stirring assembly to rotate to stir the fermentation broth, achieving the effect of primary stirring; the rotation of the rotating shaft drives the stirring assembly to generate centrifugal force, and the gravity end drives the diversion pipe to slide through the centrifugal force, thereby driving the stirring vanes to unfold to strengthen the stirring of the fermentation broth, realizing the secondary stirring of the fermentation broth only by using centrifugal force without additional driving; the centrifugal force is controlled by adjusting the rotation speed of the rotating shaft, and further the effect of the secondary stirring is controlled.

[0023] 2. The gravity end cooperates with the anti-blocking vibration assembly to cause the gravity end to be squeezed by the convex block, making the stirring vanes swing reciprocally, further strengthening the disturbance of the fermentation broth, and achieving the purpose of tertiary stirring. Multi-stage stirring is adopted to meet the requirements of different fermentation stages, ultimately making the fermentation broth more evenly mixed and improving the fermentation quality and efficiency.

[0024] 3. By means of the connected design of the water pump, the rotating shaft and the stirring assembly, the fermented liquid is transported from the stirring assembly and the rotating shaft to the intelligent detection device through the water pump. The intelligent detection device detects the spore rate of the fermented liquid, achieving the purpose of automatically sampling the fermented liquid and intelligently detecting the spore rate. After the detection, the fermented liquid is transported back to the fermentation tank in the reverse direction through the water pump, achieving the purpose of fermented liquid reflux and avoiding waste of the fermented liquid.

[0025] 4. The rotating shaft can not only drive the defoamer and the stirring assembly, but also adjust the state of the stirring blades on the stirring assembly by adjusting the rotating speed of the rotating shaft. Cooperating with the anti-blocking vibration assembly, the stirring blades can also be made to swing reciprocally, and can also cooperate with the water pump to sample the fermented liquid, achieving the purpose of achieving multiple driving effects with only one driving part, namely the rotating shaft.

[0026] 5. The floating plate is used to drive the entire defoamer to float automatically following the liquid level of the fermented liquid, ensuring that the defoamer is always located in the foam area, making the defoaming efficiency reach the best, and avoiding the complicated operation of manual adjustment. By the rotation of the rotating shaft, the strip-shaped vertical grooves on it are repeatedly engaged with and disengaged from the ball bearings, thereby driving the vibration rod to produce a reciprocating vibration effect. The vibration rod drives the thorn needle to vibrate reciprocally, removing the foam generated at the top of the fermented liquid, achieving the defoaming effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The anti-blocking vibration assembly 8 includes a convex block 81. A flexible brush plate 82 is installed on the convex block 81. The convex block 81 is installed in the fermentation tank 2.

[0041] Working principle of the present invention: The staff adds fermentation broth into the fermentation tank 2 through the feed port on the end cover 3. Since the floating plate 623 and the sliding tube 622 are made of lightweight materials, the floating plate 623 drives the entire defoamer 6 to float to the top of the fermentation broth. The control system turns on the drive motor 4, and the drive motor 4 drives the water pump 9 to rotate through a connecting piece. The water pump 9 drives the rotating shaft 5 to rotate through a rigid pipe fitting. When the rotating shaft 5 rotates, the strip-shaped vertical groove 52 deviates from its original position, squeezing out the ball 633 originally fitted in the strip-shaped vertical groove 52. The ball 633 drives the vibrating rod 631 to slide and compress the vibrating spring 634. When the next strip-shaped vertical groove 52 rotates to the position of the ball 633, the compressed vibrating spring 634 drives the vibrating rod 631 to rebound, and the ball 633 is fitted into the strip-shaped vertical groove 52 again. This cycle makes the vibrating rod 631 produce a reciprocating vibration effect. The vibrating rod 631 drives the thorn needle 632 to vibrate reciprocally, thereby removing the foam generated at the top of the fermentation broth.

[0042] When the rotating shaft 5 rotates, it drives the stirring assembly 7 to rotate. The blades 722 on the stirring rod 72 stir the fermentation broth, making the fermentation broth fully mixed to achieve the effect of primary stirring. The control system changes the rotation speed of the drive motor 4 according to the fermentation condition. When it is necessary to improve the fermentation quality or efficiency, the control system increases the motor speed, so that the rotating shaft 5 drives the stirring assembly 7 to rotate rapidly. The rotation generates centrifugal force. When the centrifugal force reaches the preset value, the gravity end 742 drives the diversion pipe 741 to overcome the elastic force of the return spring 75 and slide along the transmission pipe 721. The return spring 75 is stretched. The diversion pipe 741 drives the sliding strip 744 to slide. The sliding strip 744 drives the stirring blade 73 to deflect through the tooth groove 7441, and the stirring blade 73 unfolds. The stirring area of the stirring assembly 7 for the fermentation broth increases, strengthening the stirring of the fermentation broth to achieve the purpose of secondary stirring. The faster the rotation speed of the rotating shaft 5, the greater the centrifugal force of the stirring assembly 7, the greater the sliding distance of the gravity end 742 driving the diversion pipe 741, the greater the unfolding amplitude of the stirring blade 73, and the stronger the stirring effect on the fermentation broth. By controlling the centrifugal force, the control of the secondary stirring effect is realized; When the stirring blade 73 is fully deployed, the gravity end 742 drives the diversion pipe 741 to extend to the maximum distance. At this time, the position where the gravity end 742 is located can reach the anti-clogging vibration assembly 8. The gravity end 742 generates extrusion with the convex block 81, and the gravity end 742 is compressed and retracted, so as to slide over the convex block 81. When the gravity end 742 slides past, the filter screen 743 thereon generates friction with the flexible brush plate 82 on the convex block 81, and the flexible brush plate 82 cleans the filter screen 743 to prevent the filter screen 743 from being blocked, thus affecting the sampling of the fermentation broth; during the retraction process of the gravity end 742, the stirring blade 73 is synchronously retracted. After the gravity end 742 bypasses the convex block 81, it drives the stirring blade 73 to deploy again under the action of centrifugal force. This process repeats, causing the stirring blade 73 to reciprocally deploy and retract, forming a swing, further strengthening the perturbation of the fermentation broth, achieving the purpose of three-stage stirring. Finally, the fermentation broth is evenly mixed under the action of multi-stage stirring, and the fermentation quality and efficiency are improved.

[0043] The control system intermittently turns on the water pump 9. The water pump 9 causes the rotating shaft 5 and the stirring assembly 7 to generate suction. The fermentation broth is filtered through the filter screen 743 and flows into the diversion pipe 741 from the sampling hole 746. After passing through the corrugated pipe 745, it is then successively transported to the intelligent detection device by the water pump 9 through the diversion hole 711, the side hole 53, and the vertical flow channel 51. The intelligent detection device detects the spore rate of the fermentation broth, achieving the purpose of automatic sampling and intelligent detection of the spore rate. After the detection is completed, the fermentation broth is reversely transported back into the fermentation tank 2 by the water pump 9, achieving the purpose of fermentation broth reflux and avoiding waste of the fermentation broth. When the fermentation is completed, the control system turns off the driving motor 4 and uses the water pump 9 to pump out the fermentation broth.
