Description

Technical Field

[0001] The present application relates to the field of fermentation equipment, and particularly to an efficient stirring system for an improved microbial fermentation equipment. Background Art

[0002] Fermentation is an important method for product processing. Fermentation tanks are widely used in industries such as beverages, chemicals, food, dairy products, seasonings, brewing, and pharmaceuticals, mainly for culturing microorganisms.

[0003] During the process of microorganism cultivation, the reproduction rates of microorganisms in the fermentation tank are not completely consistent, and there are obvious differences at the bottom, in the middle, and at the corners of the tank. Therefore, the concentrations of nutrients consumed, heat, and metabolites produced by microorganism reproduction are different, and the concentrations of metabolites and nutrients, as well as the temperature, will directly affect the cultivation of microorganisms, thus greatly affecting the fermentation effect. Therefore, during the process of microbial fermentation, the performance of the stirring mechanism of the fermentation tank directly affects the fermentation efficiency and product quality.

[0004] However, in traditional technologies, the stirring mechanism in the fermentation tank usually only includes a stirring shaft arranged along the height direction of the fermentation tank. A plurality of stirring rods are fixedly connected to the side wall of the stirring shaft. By rotating the stirring shaft, the plurality of stirring rods are driven to rotate, so as to stir the fermented substances in the fermentation tank. Although the traditional stirring system can meet the basic mixing requirements, there is still room for improvement in terms of stirring efficiency and temperature uniformity. Summary of the Utility Model

[0005] In order to improve the stirring efficiency and temperature uniformity, the present application provides an efficient stirring system for an improved microbial fermentation equipment.

[0006] An efficient stirring system for an improved microbial fermentation equipment provided by the present application adopts the following technical solutions:

[0007] An efficient stirring system for an improved microbial fermentation equipment includes a tank body. A stirring mechanism is arranged inside the tank body. The stirring mechanism includes a stirring shaft. The upper end of the stirring shaft is rotatably connected to the tank body. The stirring shaft is of a hollow structure, and an adjusting rod is vertically slidably connected inside the stirring shaft. A plurality of mounting holes are formed in the side wall of the stirring shaft. A pair of guiding blocks are fixedly connected at each mounting hole. A plurality of connecting rods are hinged to the side wall of the adjusting rod. One connecting rod corresponds to one mounting hole. One end of the connecting rod passes through between a pair of guiding blocks and extends out of the inside of the stirring shaft along the mounting hole. A stirring member is fixedly connected to the end of the connecting rod away from the adjusting rod. An adjusting mechanism for driving the adjusting rod to lift along the stirring shaft is connected to the adjusting rod. A driving mechanism for driving the stirring shaft to rotate is connected to the stirring shaft.

[0008] By adopting the above technical solution, the driving mechanism is started to drive the stirring shaft to rotate. The rotation of the stirring shaft drives the adjusting rod, the connecting rod and each stirring member to rotate. Each stirring member rotates around the stirring shaft to stir the fermented material in the tank. At the same time, the adjusting mechanism is started to drive the adjusting rod to move up and down. The adjusting rod moves up and down along the stirring shaft to drive each connecting rod to move up and down. When each connecting rod rises until it is higher than a corresponding pair of guiding blocks, the end of the connecting rod away from the adjusting rod drives the corresponding stirring member to swing downward. When each connecting rod descends until it is lower than a corresponding pair of guiding blocks, the end of the connecting rod away from the adjusting rod drives the corresponding stirring member to swing upward. In this way, while the stirring member rotates around the stirring shaft, the stirring member swings up and down, further stirring the fermented material, which is beneficial to improving the stirring efficiency and temperature uniformity.

[0009] Preferably, the stirring member includes a horizontally arranged stirring blade one and a vertically arranged stirring blade two, and the stirring blade one and the stirring blade two intersect and are fixed to each other.

[0010] By adopting the above technical solution, the arrangement of the stirring blade one and the stirring blade two is convenient for increasing the stirring area of the stirring member, thereby improving the stirring efficiency.

[0011] Preferably, a plurality of corrugated pipes are fixedly connected to the side wall of the stirring shaft. One end of each corrugated pipe is fixedly connected to a corresponding mounting hole, and the other end is fixedly connected to a stirring member. The corrugated pipe covers the corresponding connecting rod and mounting hole inside.

[0012] By adopting the above technical solution, the corrugated pipe covers the connecting rod and the mounting hole inside, reducing the occurrence of the fermented material entering the inside of the stirring shaft through the mounting hole. At the same time, the corrugated pipe does not affect the up and down swing of the connecting rod and the stirring member.

[0013] Preferably, each of the guiding blocks is cylindrical.

[0014] By adopting the above technical solution, it is convenient for the connecting rod to pass between a pair of guiding blocks and move relative to a pair of guiding blocks.

[0015] Preferably, each of the guiding blocks is rotatably connected to the stirring shaft.

[0016] By adopting the above technical solution, when the connecting rod swings up and down, the rotating guiding blocks facilitate the smoother movement of the connecting rod.

[0017] Preferably, the upper end of the stirring shaft penetrates through the upper top wall of the tank. The driving mechanism includes a gear one coaxially and fixedly connected to the upper end of the stirring shaft. A gear two is meshed with one side of the gear one. A driving motor is fixedly connected to the upper top wall outside the tank. The output shaft of the driving motor is coaxially and fixedly connected to the gear two, and the diameter of the gear two is smaller than that of the gear one.

[0018] By adopting the above technical solution, when the driving motor is started, the output shaft of the driving motor drives the second gear to rotate, and the rotation of the second gear drives the first gear and the stirring shaft to rotate. The diameter of the second gear being smaller than that of the first gear serves as a speed reducer.

[0019] Preferably, the upper end surface of the stirring shaft is open, the upper end of the adjusting rod extends out along the opening of the stirring shaft, the adjusting mechanism includes an adjusting plate fixedly connected to the upper end of the adjusting rod, a driving cylinder is fixedly connected to the outer side wall of the stirring shaft, and the piston rod of the driving cylinder is vertically upward and fixedly connected to the adjusting plate.

[0020] By adopting the above technical solution, when the driving cylinder is started, the lifting of the piston rod of the driving cylinder can drive the adjusting plate and the adjusting rod to reciprocate along the length direction of the stirring shaft, so that each stirring member can be driven to reciprocate up and down, and the operation is simple and convenient.

[0021] Preferably, an elastic sealing block is fixedly connected to the opening at the upper end of the stirring shaft, and the upper end of the adjusting rod penetrates through the elastic sealing block and is slidably connected relative to the elastic sealing block.

[0022] By adopting the above technical solution, the elastic sealing block seals the opening at the upper end of the stirring shaft, reducing the occurrence of external impurities entering the inside of the stirring shaft and affecting the movement of the adjusting rod. At the same time, the elastic sealing block does not affect the lifting of the adjusting rod.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. While the stirring member rotates around the stirring shaft, the stirring member swings up and down, further stirring the fermented material, which is beneficial to improving the stirring efficiency and temperature uniformity;

[0025] 2. Reducing the occurrence of the fermented material entering the inside of the stirring shaft through the mounting holes;

[0026] 3. The structures of the driving mechanism and the adjusting mechanism are both relatively simple and can achieve the required effects. Description of the Drawings

[0032] The following further elaborates on this application Figures 1-4 in detail with reference to the accompanying drawings.

[0033] The embodiment of this application discloses an efficient stirring system for an improved microbial fermentation device. Referring to Figure 1 and Figure 2 , the stirring system includes a tank body 1. A feed pipe 11 is fixedly connected to the upper surface of the tank body 1, a discharge pipe 12 is fixedly connected to the lower surface of the tank body 1, and a support frame 13 for supporting the tank body 1 is fixedly connected to the lower end of the tank body 1. A stirring mechanism 2 is arranged inside the tank body 1. The stirring mechanism 2 includes a stirring shaft 21. The stirring shaft 21 is arranged vertically, and the upper end of the stirring shaft 21 is rotatably connected to the tank body 1 through a bearing. The stirring shaft 21 is of a hollow structure, and an adjusting rod 22 is vertically slidably connected inside it.

[0034] Referring to Figure 2 and Figure 3 , a plurality of mounting holes 211 are formed in the side wall of the stirring shaft 21 along its length direction. A pair of guide blocks 23 are connected at each mounting hole 211. Each guide block 23 is arranged in a cylindrical shape and is rotatably connected to the stirring shaft 21. A plurality of connecting rods 24 are hinged to the side wall of the adjusting rod 22, and one connecting rod 24 corresponds to one mounting hole 211. One end of the connecting rod 24 passes through between a pair of guide blocks 23 and extends out of the inside of the stirring shaft 21 along the mounting hole 211. The end of the connecting rod 24 far from the adjusting rod 22 is fixedly connected to a stirring member 25. An adjusting mechanism 3 for driving the adjusting rod 22 to move up and down along the stirring shaft 21 is further connected to the adjusting rod 22. At the same time, a driving mechanism 4 for driving the stirring shaft 21 to rotate is connected to the stirring shaft 21.

[0035] Referring to Figure 4 , the stirring member 25 includes a horizontally arranged first stirring piece 251 and a vertically arranged second stirring piece 252. The middles of the first stirring piece 251 and the second stirring piece 252 intersect and are fixed to each other, increasing the stirring area of the stirring member 25 and improving the stirring efficiency.

[0036] Referring to Figure 2 and Figure 3, during use, first, the driving mechanism 4 drives the stirring shaft 21 to rotate. The rotation of the stirring shaft 21 drives the adjusting rod 22, the connecting rod 24, and each stirring member 25 to rotate, enabling each stirring member 25 to perform a revolution stirring around the stirring shaft 21. Meanwhile, the adjusting mechanism 3 drives the adjusting rod 22 to move up and down, and the movement of the adjusting rod 22 drives each connecting rod 24 to move up and down. During the rising process of the connecting rod 24, when the height of the end of the connecting rod 24 close to the adjusting rod 22 is higher than the corresponding pair of guiding blocks 23, the end of the connecting rod 24 far from the adjusting rod 22 will drive the corresponding stirring member 25 to swing downward.

[0037] Conversely, during the descending process of the connecting rod 24, when the height of the end of the connecting rod 24 close to the adjusting rod 22 is lower than the corresponding pair of guiding blocks 23, the end of the connecting rod 24 far from the adjusting rod 22 will drive the corresponding stirring member 25 to swing upward. In this way, while the stirring member 25 performs a revolution stirring around the stirring shaft 21, it can also swing up and down, achieving multi-angle and all-round stirring, thereby greatly improving the stirring efficiency and temperature uniformity.

[0038] A plurality of corrugated pipes 26 are also fixedly connected to the side wall of the stirring shaft 21. One end of each corrugated pipe 26 is fixedly connected to a corresponding mounting hole 211, and the other end is fixedly connected to the corresponding stirring member 25. The arrangement of the corrugated pipes 26 completely covers the connecting rod 24 and the mounting hole 211 inside it, effectively reducing the situation where the fermented material enters the inside of the stirring shaft 21 through the mounting hole 211. At the same time, due to its corrugated structural characteristics, it will not affect the up and down swing of the connecting rod 24 and the stirring member 25. Select the corrugated pipe 26 made of plastic material or metal material according to the ingredients of the fermented material.

[0039] Refer to Figure 1 and Figure 2 , the upper end of the stirring shaft 21 penetrates through the upper top wall of the tank body 1. The driving mechanism 4 includes a first gear 41 fixedly connected coaxially with the upper end of the stirring shaft 21. The first gear 41 is located outside the tank body 1, and a second gear 42 is meshed with one side of the first gear 41. The upper top wall outside the tank body 1 is fixedly connected with a driving motor 43 by bolts. The output shaft of the driving motor 43 is fixedly connected coaxially with the second gear 42, and the diameter of the second gear 42 is smaller than that of the first gear 41.

[0040] During use, by starting the driving motor 43 to drive the second gear 42 to rotate, due to the meshing relationship between the second gear 42 and the first gear 41, the rotation of the second gear 42 will drive the first gear 41 and the stirring shaft 21 to rotate. And because the diameter of the second gear 42 is smaller than that of the first gear 41, it plays the role of a speed reducer, enabling the stirring shaft 21 to rotate at a relatively stable and appropriate speed.

[0041] The upper end face of the stirring shaft 21 is open, and the upper end of the adjusting rod 22 extends out of the stirring shaft 21 from the opening of the stirring shaft 21. The adjusting mechanism 3 includes an adjusting plate 31 fixedly connected to the upper end of the adjusting rod 22. A driving cylinder 32 is also fixedly connected to the outer side wall of the stirring shaft 21 by bolts. The piston rod of the driving cylinder 32 is vertically upward and is fixedly connected to the adjusting plate 31 by bolts.

[0042] During use, by starting the driving cylinder 32 and controlling the lifting movement of the piston rod, the adjusting plate 31 and the adjusting rod 22 can be driven to reciprocate along the length direction of the stirring shaft 21, so as to realize the adjustment and control of the swinging amplitude of the stirring member 25 up and down.

[0043] In order to prevent external impurities from entering the inside of the stirring shaft 21 and affecting the normal operation of the adjusting rod 22 and prolong the service life of the equipment, an elastic sealing block 5 is also fixedly connected to the upper end opening of the stirring shaft 21 by clamping. The elastic sealing block 5 is made of an elastic material such as rubber, and is provided with a through hole matching the adjusting rod 22 for the adjusting rod 22 to pass through and be slidably connected relative to the elastic sealing block 5. Such a setting not only ensures that the adjusting rod 22 can smoothly perform the lifting movement, but also effectively prevents external impurities from entering the inside of the stirring shaft 21.

[0044] The implementation principle of the high-efficiency stirring system of the improved microbial fermentation equipment in the embodiment of the present application is as follows: start the driving motor 43 to drive the stirring shaft 21 to rotate, and at the same time start the driving cylinder 32 to drive the adjusting rod 22 to reciprocate up and down. At this time, the stirring shaft 21 drives each stirring member 25 to revolve around the stirring shaft 21, so as to stir the fermented material. At the same time, the stirring member 25 swings up and down to realize the vertical stirring of the fermented material, which is beneficial to improving the stirring efficiency of the fermented material inside the tank body 1.

[0045] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
