Detailed Embodiments
[0027] The present invention will be further described below in conjunction with embodiments and the accompanying drawings.
[0028] As Figure 1-6 shown, a multi-stage microbial continuous fermentation device includes a frame 1. The frame 1 is a rectangular base structure and serves as the support main body of the device. At both ends on the upper side of the frame 1, support plates 11 are oppositely arranged. An adjustment shaft 12 is provided on each support plate 11, and the support plate 11 plays a role in supporting the adjustment shaft 12. An alternating rotation structure is connected between the two adjustment shafts 12 on both sides. The attitude of the alternating rotation structure can be adjusted by a pair of adjustment shafts 12, and continuous fermentation is realized by using the alternating rotation structure.
[0029] The alternating rotation structure includes a pair of rotating disks 2, and the pair of rotating disks 2 are respectively connected to the adjustment shafts 12 on both sides. The pair of rotating disks 2 can be driven to rotate by the adjustment shafts 12. A number of connecting rods 9 are distributed between the pair of rotating disks 2. The connecting rods 9 are located on the outer periphery, so that the pair of rotating disks 2 form a rolling cage through the connecting rods 9. A plurality of pairs of connection stations 3 are symmetrically arranged along the circumferential direction on the pair of rotating disks 2. The number of connection stations 3 is at least three, and the connection stations 3 are arranged in an annular array on the pair of rotating disks 2. Containers for fermentation are arranged between the opposite connection stations 3. The connecting rods are located on the outer periphery of the containers for fermentation.
[0030] One end of the adjustment shaft 12 on one side is connected with a indexing power assembly 4. The indexing power assembly 4 is used to drive the pair of rotating disks 2 to rotate by indexing. The pair of rotating disks 2 can be controlled by the indexing power assembly 4 to rotate by indexing according to the number of connection stations 3. The angle of its single rotation is the included angle between a pair of connection stations 3. A fermentation container 5 is connected between a pair of opposite connection stations 3. The fermentation container 5 is a cylindrical barrel. Adjacent fermentation containers 5 are connected by a communication assembly 6. The rotation of a plurality of fermentation containers 5 can be adjusted by the indexing power assembly 4, so that the fermentation containers 5 on different connection stations 3 are respectively in a high position and a low position. By switching the communication assembly 6 between the fermentation containers 5, it can be controlled that the fermentation container 5 in the high position transfers the fermented material to the fermentation container 5 in the low position, and then resets and continues to feed. Taking three fermentation containers 5 as an example, specifically, they are fermentation container 5A, fermentation container 5B, and fermentation container 5C. First, materials are added to the fermentation container 5A. After fermentation for a period of time, the fermented material is transferred to the fermentation container 5B through the communication assembly 6, and new fermented material is injected into the fermentation container 5A. When the fermentation in the fermentation container 5B is completed, the indexing power assembly 4 is used to control the fermentation container 5B to be in the high position and feed the material to the fermentation container 5C through the communication assembly 6. Then, the new fermented material in the fermentation container 5A is refilled into the fermentation container 5B. After the fermentation in the fermentation container 5C is completed, it is discharged from the material outlet, and the above process is repeated to achieve continuous fermentation.
[0031] A rotary auger 7 is installed on the opposite connection station 3, and the rotary auger 7 is located inside the fermentation container 5. One end of the rotary auger 7 penetrates through one side support plate 11, and a rotary drive assembly 8 is arranged on the support plate 11. The rotary drive assembly 8 is linked with the rotary auger 7. During fermentation, in order to enable the materials to be fully and evenly fermented and maintain the normal temperature in the fermentation chamber, the rotary drive assembly 8 is used to slowly drive a plurality of rotary augers 7 to stir the fermented materials.
[0032] Both ends of the fermentation container 5 are provided with end heads 51. The end heads 51 at both ends are connected to the middle section of the fermentation container 5 by tie bolts. A pair of flange heads 52 are respectively arranged on the end heads 51 at both ends.

[0034] The connected component 6 includes a connected channel 61 which is a rectangular through slot. The connected channel 61 is respectively connected to two adjacent fermentation cylinders. A channel switch 62 is arranged in the middle of the connected channel 61. The connected channel 61 connects a pair of adjacent fermentation containers 5. By using the channel switch 62 to switch the connected channel 61 on and off, the material can pass through. The channel switch 62 includes a rotating groove 621. The rotating groove 621 is arranged in the middle of the connected channel 61. A rotating through seat 622 is assembled on the rotating groove 621. The inner diameter of the rotating groove 621 is larger than the width of the connected channel 61. A through groove 623 with the same width as the connected channel 61 is opened at the center of the rotating through seat 622. The end of the rotating shaft seat extends out an adjusting knob 624. The adjusting knob 624 penetrates through the rotating groove 621. The diameter of the rotating through seat 622 matches the rotating groove 621. By rotating the adjusting knob 624, the rotating through seat 622 can be driven to rotate, and then the connected channel 61 can be blocked by the rotating through seat 622. The width of the through groove 623 arranged on the rotating through seat 622 matches the width of the connected channel 61. By controlling the through groove of the rotating through seat 622 to communicate with the connected channel 61, the material can pass through. On the contrary, the two sides of the rotating groove 621 can be blocked by the rotating through seat 622 to prevent the material from passing through.
[0035] The rotation driving assembly 8 includes a rotation motor 81. The rotation motor 81 is arranged on the frame 1. A speed reducer is connected to one side of the rotation motor 81.

Annular moving internal teeth 85 are evenly arranged on the inner side of the adjusting wheel 82. A rotating gear 84 is arranged at the end of the rotating auger 7 and meshes with the annular moving internal teeth 85.
[0036] By the rotation motor 81, the rotation of the speed reducer can be controlled. The speed reducer drives the adjusting wheel 82 through the driving wheel 83 by a belt drive, so that the adjusting wheel 82 rotates. Then the adjusting wheel 82 drives the annular moving internal teeth 85 to rotate. The annular moving internal teeth 85 cooperate with the rotating gear 84, so that the rotating gear 84 drives the rotating auger 7 to rotate slowly to stir the material.
[0037] The fermentation condition controller includes a comprehensive sensor 55. The comprehensive sensor 55 is inserted into the fermentation cylinder. The comprehensive sensor 55 includes a temperature sensor, an oxygen concentration sensor and a pressure sensor. The comprehensive sensor 55 is inserted into the fermentation cylinder with an integrated support rod. A temperature controller 56 and an air vent control pipe 57 are arranged on the fermentation cylinder.
[0038] Inserted into the fermentation tank through the integrated sensor 55, the temperature sensor, oxygen concentration sensor, and pressure sensor on the integrated sensor 55 are used to detect the temperature, oxygen concentration, and air pressure in the fermentation container 5 respectively. Thus, the temperature is adjusted by controlling the temperature controller 56, and air is introduced or discharged through the ventilation control pipe 57 to precisely control the fermentation reaction conditions.
[0039] Generally speaking, in this multi-stage continuous microbial fermentation device, the mechanical linkage indexing rotary system replaces the traditional pumping pipeline, enabling the material to fall into the fermentation container 5 under the action of gravity. By controlling different fermentation containers 5 at high and low positions, the rapid transfer of materials is achieved. The connection of multiple fermentation containers 5 together and isolation from the outside avoid the occurrence of pollution. Moreover, multiple augers are connected to the rotary drive assembly 8 in the multiple fermentation containers 5 to slowly stir the materials, effectively protecting the cleanliness of the fermentation products and improving the fermentation efficiency at the same time.
