[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides a multi-stage linkage microbial fermentation device, which includes a fermenter 1, a vertical rod 4, a reciprocating screw 3, a secondary stirring structure 2, a sleeve 24, a secondary stirring rod 21, a limiting rod 22, a sliding component 23, a sliding block 231, and a tip plate 232. To achieve stirring of microorganisms within the fermenter 1, the vertical rod 4 is rotatably connected to the fermenter 1 via flanges and bearings. The fermenter 1 has an internal chamber for microbial fermentation. During use, the microorganisms to be fermented and substances that interact with the microorganisms are placed inside the fermenter 1. To drive the secondary stirring structure 2 to move up and down within the fermenter 1, the two ends of the reciprocating screw 3 are welded or connected to the end of the vertical rod 4 away from the fermenter 1 via bolts. During use, the reciprocating screw 3 rotates synchronously with the vertical rod 4. The working principle of the reciprocating screw 3 is achieved by converting rotational motion into linear motion. It consists of a screw and a guide rail. The screw has a helical thread, and the guide rail has a corresponding thread groove. When the lead screw rotates, the guide rail moves along the lead screw axis, thus achieving linear motion. Specifically, the rotation of the lead screw causes the side of the spiral groove to push the sliding block 231, which is placed in the spiral groove, to reciprocate axially. This design allows the sliding block 231 to reciprocate without changing the direction of rotation of the main shaft. In addition, the head of the end of the upright 4 has an internal crescent-shaped pin, i.e., a flexible slider or nut, which needs its own smooth trajectory to ensure smooth and uniform movement. The above is the prior art and will not be described in detail below.

[0027] To enable the secondary stirring structure 2 to move vertically within the fermenter 1, the secondary stirring structure 2 is longitudinally slidably connected to the reciprocating lead screw 3. It should be noted that the secondary stirring structure 2 includes a sleeve 24, a secondary stirring rod 21, and a limiting rod 22. Specifically, the sleeve 24 is slidably fitted onto the reciprocating lead screw 3. Both the sleeve 24 and the reciprocating lead screw 3 are circular, with the inner diameter of the sleeve 24 slightly larger than the outer diameter of the reciprocating lead screw 3. The sleeve 24 and the reciprocating lead screw 3 are fitted together. The end of the secondary stirring rod 21 is welded to the outer wall of the sleeve 24 or detachably connected via bolts, similarly, the end of the limiting rod 22 is welded to the outer wall of the sleeve 24 or detachably connected via bolts. The system is connected, and two sets of limiting rods 22 are provided, with two limiting rods 22 in each set. When the sleeve 24 moves up and down on the reciprocating screw 3 via the sliding block 231, the limiting rods 22 and the secondary stirring rod 21 will stir the fermented material near the reciprocating screw 3 and the upright rod 4, reducing the probability of the fermented material near the reciprocating screw 3 and the upright rod 4 becoming stationary. One end of the limiting rod 22 is connected to the outer wall of the sleeve 24, and the other end of the limiting rod 22 is slidably connected to the sliding groove 16 integrally formed on the side wall of the fermentation tank 1. The sliding groove 16 and the limiting rod 22 are connected in a dovetail sliding connection, where the cross-section of the sliding groove 16 is dovetail-shaped, wider at the top and narrower at the bottom, and the bottom of the limiting rod 22 has a V-shaped structure. The initial position of the limiting rod 22 is located at the upper wide part of the sliding groove 16. When moving, the "V" shape at the bottom of the limiting rod 22 is restricted to the narrow side of the lower half of the dovetail groove, thereby ensuring a linear motion trajectory. This design restricts the degree of freedom of the limit rod 22 in the direction perpendicular to the guide rail, allowing it to move only in the dovetail direction. This is the prior art, and will not be described in detail below.

[0028] To ensure that the sleeve 24 can reciprocate up and down on the reciprocating screw 3, a sliding member 23 is connected inside the sleeve 24. The sliding member 23 has a sliding block 231 slidably connected on the reciprocating screw 3. The sliding block 231 is rotated by the screw of the upright rod 4, causing the side of the spiral groove to push the sliding block 231, which is placed in the spiral groove, to make axial reciprocating motion. The two ends of the sliding block 231 have tip plates 232, which are as follows: Figure 5 The end shown, away from the sliding block 231, is designed as a pointed tip. Proper cleaning of the spiral groove inside the upright 4 is necessary to prevent clogging between the spiral groove and the sliding block 231. Figure 5 The image shown is only one of the shapes of the tip plate 232. The shape of the tip plate 232 is not unique when in use. It will be designed according to the specific distribution of the spiral grooves inside the upright 4 to avoid mechanical interference.

[0029] It is worth noting that the upright 4 is welded or bolted with an active rotating structure, which includes a crossbar 41 connected to the upright 4. The crossbar 41 is bolted to the upright 4 and rotates synchronously with the upright 4 during use.

[0030] It should be further explained that the active stirring rod 42 is integrally molded on the crossbar 41. The active stirring rod 42 and the crossbar 41 are designed with a "U" shaped groove, and the two "U" shaped grooves are mirrored. When the upright rod 4 rotates, it drives the crossbar 41 and the active stirring rod 42 to rotate, so as to carry out fermentation and stirring treatment of microorganisms in the fermenter 1.

[0031] In some embodiments, during use, the microorganisms to be fermented and the substances that act on the microorganisms are placed in the fermentation tank 1. The active stirring rod 42 is integrally molded onto the crossbar 41, wherein the active stirring rod 42 and the crossbar 41 are designed with a "U"-shaped groove, and the two "U"-shaped grooves are mirror-distributed. When the upright rod 4 rotates, it drives the crossbar 41 and the active stirring rod 42 to rotate, thereby fermenting and stirring the microorganisms in the fermentation tank 1. At the same time, during use, the reciprocating screw 3 will rotate with the upright rod 4. At this time, both the sleeve 24 and the reciprocating screw 3 are circular, and the inner diameter of the sleeve 24 is slightly larger than the outer diameter of the reciprocating screw 3. The sleeve 24 and the reciprocating screw 3 are connected. The end of the secondary stirring rod 21 is welded to the outer wall of the sleeve 24 or detachably connected by bolts. Similarly, the end of the limiting rod 22 is welded to the outer wall of the sleeve 24 or detachably connected by bolts. Two sets of limiting rods 22 are provided, with two rods in each set. When the sleeve 24 moves up and down on the reciprocating screw 3 via the sliding block 231, the limiting rod 22 and the secondary stirring rod 21 will stir the fermented material near the reciprocating screw 3 and the upright rod 4, reducing the probability of the fermented material remaining stationary around the reciprocating screw 3 and the upright rod 4. The tip plate 232, for example... Figure 5 The end shown, away from the sliding block 231, is designed as a pointed tip. Proper cleaning of the spiral groove inside the upright 4 is necessary to prevent clogging between the spiral groove and the sliding block 231. Figure 5 The image shown is only one of the shapes of the tip plate 232. The shape of the tip plate 232 is not unique when in use. It will be designed according to the specific distribution of the spiral grooves inside the upright 4 to avoid mechanical interference.

[0032] Fermentation tank 1 contains two heating plates 15, each with a heating wire. The working principle is based on the thermal effect of electric current; that is, when current passes through a resistor, the current does work, consuming electrical energy and generating heat. This phenomenon is called the thermal effect of electric current. Specifically, the heating wire generates heat through the current, realizing the conversion of electrical energy into thermal energy. Its working principle can be described by Joule's law, which states that the amount of heat is directly proportional to the square of the current, the resistance of the conductor, and the duration of the current flow. When selecting a model, a model suitable for the equipment should be chosen. This is existing technology and will not be elaborated further. The two heating plates 15 and two sliding grooves 16 are equidistantly distributed in a circle within fermentation tank 1. The heating plates 15 heat the interior of fermentation tank 1, increasing the fermentation speed of microorganisms.

[0033] The fermenter 1 is detachably connected to the cover 14 via an existing snap-fit ​​structure. The cover 14 on the top of the fermenter 1 can be opened periodically to clean the inside of the fermenter 1. The cover 14 is equipped with a detection structure 13, and the detection wire of the detection structure 13 extends into the fermenter 1. The detection structure 13 contains a temperature sensor. When in use, the temperature sensor can detect the temperature inside the fermenter 1 in real time and feed it back to the control panel. The real-time temperature of the heating plate 15 is controlled by the control panel for precise control.

[0034] It should be further explained that a drive source 11 is connected to the cover 14. The drive source 11 is a rotary motor. The output end of the drive source 11 extends into the fermentation tank 1 and is connected to the end of the upright rod 4. The drive source 11 controls the upright rod 4 to rotate, which drives the reciprocating screw 3 to rotate synchronously.

[0035] It should be noted that the top of the cover 14 is provided with a feed inlet 12, and feeding is carried out at the feed inlet 12. The feed inlet 12 extends into the fermentation tank 1 and is connected to the fermentation tank 1.

[0036] In some embodiments, feeding is performed at the feed inlet 12, and then the drive source 11 is controlled to rotate. The drive source 11 drives the upright 4 to rotate, which in turn drives the reciprocating screw 3 to rotate synchronously, realizing the function of multi-level linkage. During fermentation, the detection structure 13 has a temperature sensor. When in use, the temperature sensor can detect the temperature in the fermentation tank 1 in real time and feed it back to the control panel. The real-time temperature of the heating plate 15 is controlled through the control panel for precise control.

[0037] Working principle: When using this microbial fermentation device, an external power supply is used. First, feeding is performed at the inlet 12. Then, the drive source 11 is controlled to rotate, which drives the upright rod 4 to rotate, and drives the reciprocating screw 3 to rotate synchronously. When the upright rod 4 rotates, it drives the crossbar 41 and the active stirring rod 42 to rotate, thus fermenting and stirring the microorganisms in the fermentation tank 1. At the same time, the reciprocating screw 3 will rotate with the upright rod 4 during use. At this time, both the sleeve 24 and the reciprocating screw 3 are circular designs. The inner diameter of the sleeve 24 is slightly larger than the outer diameter of the reciprocating screw 3. The sleeve 24 and the reciprocating screw 3 are sleeved together. The end of the secondary stirring rod 21 is welded to the outer wall of the sleeve 24 or detachably connected by bolts, etc. Similarly, the end of the limiting rod 22 is welded to the outer wall of the sleeve 24 or detachably connected by bolts, etc., and there are two sets of limiting rods 22, with two limiting rods in each set. When the sleeve 24 moves up and down on the reciprocating screw 3 through the sliding block 231, the limiting rod 22 and the secondary stirring rod 21 will stir the fermented material near the reciprocating screw 3 and the upright rod 4, realizing the function of multi-stage linkage, and reducing the probability of the fermented material around the reciprocating screw 3 and the upright rod 4 becoming stationary.

[0038] Among them, the tip plate 232, such as Figure 5 The end shown, away from the sliding block 231, is designed as a pointed tip. Proper cleaning of the spiral groove inside the upright 4 is necessary to prevent clogging between the spiral groove and the sliding block 231. Figure 5 The image shown is only one of the shapes of the tip plate 232. The shape of the tip plate 232 is not unique in use. It will be designed according to the specific distribution of the spiral grooves inside the upright 4 to avoid mechanical interference.

[0039] During fermentation, the detection structure 13 contains a temperature sensor. When in use, the temperature sensor can monitor the temperature inside the fermentation tank 1 in real time and feed it back to the control panel. The control panel controls the real-time temperature of the heating plate 15 for precise control, and finally completes the operation of the microbial fermentation device.
