Description

Technical Field

[0001] The invention belongs to the technical field of tank fermentation, and in particular relates to a biological fermentation device for Chinese herbal medicine. Background Art

[0002] Traditional Chinese medicine prescriptions are usually compound prescriptions made of multiple Chinese medicines in different proportions, in which the active molecules of each Chinese medicine are complex and have different contents, including both beneficial and toxic components;

[0003] Probiotic fermented Chinese medicine can improve the efficacy of Chinese medicine through microbial biotransformation. For example, the compound preparations obtained by fermenting single or compound Chinese medicines with lactic acid bacteria, yeast and bacillus under suitable culture conditions have the effect of improving growth performance and vaccine antibody levels. In addition, microbial fermentation can also decompose and transform the complex components of Chinese medicine into new active substances or weaken the toxic substances in Chinese medicine, thereby regulating the quality of Chinese medicine.

[0004] Compared with traditional fermentation methods (ceramic jars or wooden barrels), fermentation tank fermentation can not only shorten the fermentation cycle, reduce external pollution, and ensure product purity, but also accurately control fermentation conditions such as temperature, humidity, pH value and dissolved oxygen, provide a high-quality growth environment for microorganisms, and ensure the stability and consistency of the fermentation process;

[0005] The continuous growth and reproduction of microorganisms during the actual fermentation process causes some bacteria to remain on the inner wall of the fermentation tank. At the same time, some culture medium components are deposited on the inner wall of the tank under the stirring force. In addition, microorganisms continuously secrete metabolites such as organic acids or polysaccharides to the outside during fermentation, and polysaccharides, to a certain extent, will increase the probability of residual components of traditional Chinese medicine or residual microbial cells adhering to the inner wall of the fermentation container.

[0006] Traditional fermentation tank cleaning processes usually use the stirring device in the fermentation body to scrape and clean the inner wall of the tank while the fluid is flushing, or even rely on operators to clean the inner wall of the tank. While the former is both real-time and convenient, there are problems of single correspondence and solidification between the cleaning body and the fermentation tank.

[0007] In addition, in order to quickly guide the fermented materials in the tank to flow to the outside, chamfering is usually performed on the junction between the fermentation tank body and the bottom and the bottom itself. At this time, the applicability of traditional cleaning tools is greatly reduced. For example, the cleaning brush can only adapt to the sudden reduction of the cleaning area through the flexibility of the bristles on the main body. However, there is still the problem of different cleaning levels in different areas, that is, low relative degree and different interaction forces, which not only increases the probability of damage to the fermentation tank body, but also reduces the cleaning effect, and then increases the risk of cross-infection. The latter not only fails to ensure the integrity of the cleaning, but also increases the labor intensity of the operator to a certain extent, and increases the fermentation cost. Summary of the invention

[0008] The purpose of the present invention is to propose a biological fermentation device for Chinese herbal medicine, so as to achieve equal-position cleaning of the inner walls of fermentation tanks of different models, improve the cleanliness of the inner walls of the fermentation tanks, reduce the risk of cross-infection between previous and subsequent fermentation products, and ensure the purity and quality consistency of each batch of products.

[0042] The cleaning method of the inner wall of fermentation tanks of different models is assembled by using the above-mentioned biological fermentation device for Chinese herbal medicine, and the specific steps are as follows:

[0043] S1: First, the telescopic gas rod drives the protective frame to move away from the axis of the tank until the rubber spatula in the cylindrical box area contacts the inner wall of the tank. After that, the three-phase motor drives the middle column to drive the wide closing ring to rotate;

[0044] S2: Then, the rubber spatula in the cylindrical box area is driven by the load-sharing plate to move along the axis of the tank body until the horizontal section of the protective frame contacts the inner wall of the tank bottom. After that, the rubber spatula in the corner box area is controlled to perform supplementary cleaning and scraping processing on the inner wall of the tank bottom through the linkage of the electric telescopic rod and the narrow closing ring;

[0045] S3: Finally, the front brush, the rear brush and the flexible brush continuously make reciprocating motion on the end surface of the rubber shovel under the dual effects of fluid flushing and gas disturbance until the end surface of the rubber shovel is cleaned.

[0046] The present invention has the following beneficial effects:

[0047] 1. The present invention synchronously controls the protective frames in multiple directions through telescopic gas rods, and moves them to the specified position away from or close to the axis of the center column, so as to adapt to the cleaning of the inner walls of fermenters of different models, reduce costs, improve efficiency, simplify operations and training, and increase versatility and flexibility; at the same time, through the reciprocating sliding of the load-distributing plate, complete cleaning of fermenters of different depths is achieved, breaking through the limitation that large-volume fermenters are difficult to clean, and improving the operating capacity under special environments.

[0048] 2. The present invention breaks the limitations of the single shape and solidification of traditional scrapers through the coordinated cooperation between multiple glue spatulas, that is, the single scraper is made flexible in sections, and multiple glue spatulas can make corresponding shape adjustments due to changes in the external environment when moving, so as to adapt to the same-position cleaning of the suddenly changed area on the inner wall of the tank, which helps to improve the cleaning integrity and thoroughness of the residues on the inner wall of the tank. At the same time, through the telescopicity of the telescopic gas rod, the contact consistency between each glue spatula and the inner wall of the tank can be adjusted autonomously to avoid damage to the inner wall of the tank during the operation of the glue spatula.

[0049] 3. The present invention adjusts the compatibility between the glue spatula in the corner box area and the inner wall of the tank bottom in real time through the linkage between the electric telescopic rod and the narrow closing ring, fully ensuring the consistency of the vertical distance between the glue spatula at different positions and the corresponding areas of the tank bottom, that is, unifying the interaction force between the glue spatula and the tank bottom, while providing subsequent supplementary cleaning for the area after the glue spatula cleans the cylindrical box area, ensuring thorough cleaning of the residues on the inner wall of the tank body.

[0050] 4. The present invention uses the reciprocating motion of the bracket to prompt the plate to drive the front brush, the rear brush and the flexible brush to clean the rubber shovel working area, thereby ensuring the cleanliness of the rubber shovel body, reducing the probability of secondary contamination of the fermentation tank body by microorganisms or impurity residues in the rubber shovel body, reducing the risk of cross infection, and helping to ensure the quality stability and consistency of the fermentation products before and after.

[0076] Reference Figure 1 and Figure 3It can be seen that one end face of the can lid 1 close to the narrow engagement ring 31 is detachably installed with the can body 11 through bolts. The can body 11 is jointly composed of a circular ring section can body and an arc section can bottom. The outer wall of the can body is circumferentially and evenly clamped and installed with can ears 12. One end face of the can lid 1 away from the can body 11 is clamped and installed with a shaft disc 13 at the axis center. One end face of the shaft disc 13 away from the can lid 1 is clamped and installed with a shaft platform 14. One end of the shaft platform 14 away from the shaft disc 13 is clamped and installed with a three-phase motor 15. The output shaft of the three-phase motor 15 is clamped and installed with a middle column 16;

[0077] Refer to Figure 2 、 Figure 3 and Figure 4 It can be seen that the control unit 2 includes: a load sharing disc 21, which is slidably clamped and installed on the outer wall of the middle column 16; key grooves 22, which are evenly opened on the outer side of the load sharing disc 21; a wide engagement ring 23, which is slidably clamped and installed on the outer wall of the middle column 16 and is clamped and installed with one end face of the load sharing disc 21 close to the narrow engagement ring 31; telescopic air rods 24, at least one, and corresponding one-to-one with the positions of the electric telescopic rods 32, are clamped and installed on the outer wall of the wide engagement ring 23; a C-shaped guard frame 25, which is clamped and installed at one end of the telescopic air rod 24 away from the axis center of the middle column 16; in addition, the other horizontal section of the C-shaped guard frame 25 away from the can lid 1 is clamped and installed with the strip rail 34 in a matching manner, and between the middle position of the inner wall of the vertical section of the C-shaped guard frame 25 and the same-side plate 391 is detachably installed through bolts; a U-shaped strip 26, which is clamped and installed on the horizontal section of the C-shaped guard frame 25 close to the can lid 1 and is slidably installed with the load sharing disc 21; a tooling rack 27, which is rotatably installed between the horizontal sections of the C-shaped guard frame 25 through a rotating shaft.

[0078] Cleaning solutions for fermentation tanks of different models:

[0079] During specific implementation, the control unit 2, the main body unit 3 and the cleaning unit 4 can be moved directly above the can body 11 (at this time, the can body 11 and the can lid 1 have been separated) by means of hoisting, and then the main body unit 3, the control unit 2 and the cleaning unit 4 are moved along the axis of the can body 11 into the specified area inside the can body 11;

[0080] The driving process and adjustment process of the control unit 2 for the main body unit 3 (partially):

[0081] First, by extending or contracting the telescopic gas rod 24 (when the gas rod is compressed by external force, the internal gas is compressed, and when the pressure increases, the gas rod shortens; when the external force disappears, the internal gas pressure pushes the inner and outer sleeves to extend in the opposite direction until the initial length is restored; specifically, the telescopic gas rod 24 can be provided with a driving force by an external air pump), the protective frame 25 is prompted to move away from or close to the axis of the wide closing ring 23 (in this process, the movement stability of the protective frame 25 is further improved by the clamping limit between the workpiece strip 26 and the key groove 22, and the operation accuracy of the main unit 3 is indirectly improved), until the local main unit 3 in this direction conflicts with the inner wall of the fermentation tank body 11 and maintains a certain force (the force can be monitored and calculated by an external sensing device);

[0082] Next, the middle column 16 drives the wide closing ring 23 to rotate under the dual effects of the output shaft control of the three-phase motor 15 and the limit of the shaft disc 13. At this time, the main unit 3 (partially) starts to clean the inner wall of the fermentation tank body 11;

[0083] Finally, by rotating the fixture frame 27 180 degrees (single time), the intermittent position change of the (partial) working end of the main unit 3 is realized. Specifically, the fixture frame 27 can be driven to rotate by an external motor;

[0084] Pillow block 14: provides stable support for the three-phase motor 15, reducing the cleaning effect of working vibration on the inner wall of the tank body 11;

[0085] The tank ear 12 facilitates the operator to move, disassemble or transport the tank body 11 , thereby improving the safety of the tank body 11 to a certain extent.

[0086] Reference Figure 2 , Figure 3 , Figure 5 and Fig.10 It can be seen that the main unit 3 includes: a narrow closing ring 31, which is movably arranged in the space on one side of the axis of the tank cover 1, and the median column 16 is slidably engaged with the narrow closing ring 31; an electric telescopic rod 32, at least one, is evenly engaged with the outer wall of the narrow closing ring 31 in the circumferential direction; an ear seat 33, which is engaged with the electric telescopic rod 32 at one end away from the axis of the narrow closing ring 31; a rail 34, which is arranged in the space on one side of the narrow closing ring 31 and corresponds to the ear seat 33 one by one; a bottom guard frame 35, which is slidably engaged with the rail 34 at the middle position of the end face of the side away from the tank cover 1; a T-joint strip 36, which is rotatably engaged with the ear seat 33 and the rail 34 through a rotating shaft; an angle box 37, which is engaged with the middle position of the side of the T-joint strip 36 away from the bottom guard frame 35; a cylindrical box 38, two in a group, at least one group, and symmetrically distributed in the space on one side of the narrow closing ring 31; in addition, the cylindrical box 38 corresponds to the position of the electric telescopic rod 32 one by one;

[0087] Reference Figure 5 , Figure 6 and Figure 8 It can be seen that the corner box 37 and the cylindrical box 38 are sequentially snap-fitted with the edge plate 371 and the middle plate 372, and the middle plate 372 is evenly slidably snap-fitted with the straight rods 373 that are slidably fitted with the edge plate 371 and the cylindrical box 38 or the corner box 37 in an array, and the straight rods 373 penetrate the middle plate 372, the edge plate 371, the cylindrical box 38 or the corner box 37, and the end of the straight rods 373 away from the edge plate 371 is snap-fitted with a glue spatula 374, and the outer wall of each straight rod 373 is provided with a glue spatula 374. There are two rubber rings 375, one of which is close to the rubber spatula 374 and fixedly connected to the straight rod 373, and the other rubber ring 375 is clamped and installed with the end face of the edge plate 371 close to the rubber spatula 374. A return spring 376 sleeved and installed with the straight rod 373 is fixedly installed between the two rubber rings 375 in the same group. A horn cap 377 clamped and installed with the angle box 37 or the cylindrical box 38 is slidably mounted on the outer wall of the straight rod 373 close to the rubber spatula 374, and the cap opening faces the edge plate 371.

[0088] Reference Figure 4 and Figure 6 It can be seen that the space on one side of the tank cover 1 near the narrow ring 31 is symmetrically provided with water storage tanks 395, the number of which is two, and the space on one side of the cylindrical box 38 near the tank cover 1 is provided with a water diversion pipe 396, the end of the water diversion pipe 396 away from the axis of the tank cover 1 is clamped and installed with a nozzle 397, and the horizontal section of the side of the tank cover 1 near the protective frame 25 is clamped and installed with the nozzle 397 by a buckle, the nozzle 397 is facing the working area of ​​the glue spatula 374 at an angle of forty-five degrees, and the nozzle 397 is biased towards the side space where the glue spatula 374 actually turns;

[0089] The glue shovel 374 is designed with a rounded chamfer at one end near the bottom of the tank. In addition, the vertical distance between adjacent glue shovels 374 distributed in the same cylindrical box 38 or corner box 37 is less than the length of the glue shovel 374, and the glue shovels 374 distributed in the same group of two cylindrical boxes 38 are alternately distributed in the spatial layout, the length of the cylindrical box 38 is equal to the vertical distance between the horizontal section of the protective frame 25, and the vertical distance between the center line of the tooling frame 27 and the glue shovel 374 is less than the vertical distance between the center line of the tooling frame 27 and the vertical section of the protective frame 25.

[0090] Rubber shovel 374: Main unit 3 directly interacts with the fermentation tank:

[0091] The glue spatula 374 exists in two areas: the cylindrical box 38 area (the inner wall of the can body or the junction of the can body and the bottom) and the corner box 37 area (the inner wall of the can bottom):

[0092] Main unit 3: cylindrical box 38 area rubber spatula 374 working process description:

[0093] The aforementioned main unit 3 (partial) refers to the rubber spatula 374 in the cylindrical box 38 area;

[0094] First, the main unit 3 is moved to the designated position by the external lifting device until the glue shovel 374 (the side close to the tank cover 1) is tangent to the end of the tank body 11 close to the tank cover 1 (or the vertical distance between the glue shovel 374 and the tank cover 1 is smaller than the vertical distance between the inlet end face of the tank body 11 and the tank cover 1, so as to ensure the initial full coverage of the tank body 11 by the glue shovel 374);

[0095] Next, the cylindrical box 38 at one end of the wide closing ring 23 moves away from the cylindrical box 38, and gradually moves toward the inner wall of the fermenter while the protective frame 25 controls the tooling frame 27 to move, until the rubber spatula 374 contacts the inner wall of the fermenter and maintains a certain interaction force (when the rubber spatula 374 contacts the inner wall of the fermenter: the straight rod 373 moves toward the axis of the tank body 11 under the dual action of the reverse force of the rubber spatula 374 and the guidance of the middle plate 372 and the side plate 371. At this time, the rubber ring 375 on the side of the rubber spatula 374 moves synchronously with the straight rod 373 and gradually compresses the reset spring 376 until the interaction force between the rubber spatula 374 and the tank body 11 tends to be stable);

[0096] Finally, the load-distributing plate 21 is synchronously controlled by the middle column 16 to drive the wide closing ring 23 to rotate. At this time, the rubber shovel 374, which is in conflict with the inner wall of the fermenter, cleans and scrapes the designated area (the covered section of the rubber shovel 374 in the cylindrical box 38 area) of the inner wall of the fermenter during rotation (in this process, the cleaning liquid inside the water storage tank 395 is gradually guided to the nozzle 397 through the water pipe 396 (in specific implementation, an external hose can be used as a conveying bridge between the water pipe 396 and the water storage tank 395, and an external water pump can provide a pumping driving force) and then sprayed to the inner wall of the fermenter through the nozzle 397, and the cleaning liquid continuously flows to the remaining operation area of ​​the rubber shovel 374 under the action of gravity);

[0097] The trumpet cap 377 is used to reduce the amount of fluid retained on the outer wall of the straight rod 373 and ensure the smooth extension and retraction of the rubber spatula 374;

[0098] The purpose of leaving a blank area between adjacent plastic spatulas 374 is:

[0099] On the one hand, it reduces fluid resistance, improves flow characteristics, increases the turbulence of the cleaning liquid during flow, increases the degree of interaction between the cleaning liquid and the tank 11 and the rubber shovel 374, and improves the cleaning effect; on the other hand, it reduces the overall material used for the scraper, reduces the carrying load, and reduces the maintenance cost (without affecting the strength of the scraper);

[0100] Different cylindrical box 38 areas (taking this product as an example: divided into four areas h, i, j and k, please refer to the attached Figure 4 ) of the plastic spatulas 374 are arranged alternately in space (see attached Fig. 9 The planar coverage area of ​​the rubber spatula 374 in sections a and b is shown in the figure):

[0101] The rubber spatula 374 in the h area can cover the cleaning blank area of the rubber spatula 374 in the k area. Similarly, the i area is a re-coverage of the cleaning blank area of the h area, the j area is a re-coverage of the i area, and the k area is a re-coverage of the j area, so as to ensure the thorough cleaning of the inner wall of the can body by the rubber spatula 374 in the 38 area of the cylindrical box;

[0102] In addition, the segmented small-area scraping method of the rubber spatula 374 in different areas helps to quickly divide the impurities adhering to the inner wall of the tank body 11, improve the solubility and mixing uniformity between the cleaning liquid and the adhering impurities, thereby improving the scraping fluency and cleaning completeness of the rubber spatula 374, reducing the operating load of the wide joint ring 23, and increasing the service life of the main unit 3 (moreover, the small-volume rubber spatula 374 helps to reduce the friction between it and the fermenter, and the low friction enables the rubber spatula 374 to more easily cope with uneven, rough or curved surfaces, improving the adaptability and versatility of the scraping operation. At the same time, it can also reduce the mutual wear between the rubber spatula 374 and the surface to be scraped, extend the service life of the rubber spatula 374 and related components, and reduce the equipment maintenance cost);

[0103] The scraping process of the rubber spatula 374 in the 38 area of the cylindrical box on the junction area between the can body and the can bottom:

[0104] After the rubber spatula 374 in the 38 area of the cylindrical box rotates a specified number of turns, it can drive the wide joint ring 23 to move towards the can bottom through the load-sharing disk 21 until the horizontal section of the C-shaped guard frame 25 near the can bottom contacts the inner wall of the can bottom (reference can be made to the display diagram of the C-shaped guard frame 25 and the can bottom plane in the attached Fig.11 figure, in the E section area). Specifically, during implementation, the load-sharing disk 21 can be driven to move by an electric slider;

[0105] When the rubber spatula 374 moves to the chamfered area at the junction between the can body and the can bottom, the arc chamfer end of the rubber spatula 374 (partially) on the side near the can bottom first contacts the can bottom. After that, the rubber spatula 374 at this position continues to move towards the center of the can bottom until the interaction force between it and the tank body 11 is the same as the interaction force between the aforementioned rubber spatula 374 and the can body (the telescopic air rod 24 can be appropriately controlled to drive the cylindrical box 38 to move a certain distance towards the center area of the can bottom to adapt to the current interaction force between the rubber spatula 374 and the can bottom. Specifically, during implementation, physical information is collected in real time through an external PLC control system, and the physical information is converted into an electrical signal and transmitted to a specified central processing unit. Finally, through analysis and calculation by the central processing unit, the instruction is transmitted to the corresponding execution end in the form of an electrical signal);

[0106] It should be noted that for the停留 of the rubber spatula 374 on the side near the can bottom at the tangent position of the junction between the can body and the can bottom, during specific implementation, the precise docking of the rubber spatula 374 can be controlled through external image acquisition information and finally via the PLC control system;

[0107] Working process of the corner box 37 area glue spatula 374:

[0108] Through the reciprocating sliding of the narrow closing ring 31 (in specific implementation, the narrow closing ring 31 can be driven to move by an electric slider), the T-joint strip 36 drives the angle box 37 (at this time, the bottom guard frame 35 moves to a specified position under the guidance of the rail 34) to adjust the angle until the rubber spatula 374 in the area of ​​the angle box 37 is perpendicular to the inner wall of the tank bottom. After that, the rubber spatula 374 scrapes and cleans the tank bottom, and the working process and principle of the rubber spatula 374 in the area of ​​the cylindrical box 38 can be referred to;

[0109] See attached Fig.11 It can be seen that:

[0110] The rubber spatula 374 in the cylindrical box 38 area only supports cleaning and scraping the tank body and tank bottom (part) in the D area, and the rubber spatula 374 in the corner box 37 area only supports cleaning and scraping the tank bottom (part) in the F area. The E area is a blind area for cleaning;

[0111] At this time, the ear seat 33 can be controlled by the electric telescopic rod 32 to drive the angle box 37 to move away from the axis of the tank body 11, and then the angle between the angle box 37 and the tank bottom is readjusted until the glue shovel 374 in the area of ​​the angle box 37 completely covers the cleaning blind area of ​​the tank bottom part in the aforementioned area E;

[0112] See attached Fig.11 (G area) It can be seen that:

[0113] There is a distance between the end of the angle box 37 close to the axis of the tank body 11 and the axis of the tank bottom, with this distance as the radius and the axis of the tank bottom as the center of the circle. The tank bottom area corresponding to the aforementioned trajectory circle is the cleaning blind area of ​​the rubber spatula 374 in the angle box 37 area. However, this area is usually the outlet end of the fermentation tank. Therefore, in actual processing, the radius of the aforementioned trajectory circle is smaller than the outlet radius of the fermentation tank.

[0114] At this point, the can body, the junction between the can body and the can bottom, and the inner wall of the can bottom are completely cleaned, especially the adaptive angle adjustment of the rubber spatula 374 for different junctions between the can body and the can bottom is very targeted.

[0115] Reference Figure 6 and Figure 7 It can be seen that a side plate 391 corresponding to the position of the electric telescopic rod 32 is arranged in the space on one side of the cylindrical box 38, and a telescopic movable column 392 is clamped and installed on the end surface of the side plate 391 away from the axis of the narrow closing ring 31. There are two telescopic movable columns 392, which are symmetrically distributed. The two telescopic movable columns 392 are clamped and installed with an end plate 393 at one end away from the side plate 391, and the end plate 393 is clamped and installed with a strip plate 394 at one end away from the side plate 391.

[0116] Reference Fig.10, Fig.12 and Fig.13 As can be seen, the cleaning unit 4 includes: guide rails 41, two of which are in a group and symmetrically snap-fitted on the end of the corner box 37 away from the tank cover 1; a bracket 42, which is slidably snap-fitted on the middle position of the end face of the guide rail 41 away from the corner box 37; in addition, the opposite surface of the strip 394 is also slidably snap-fitted with the bracket 42; a wall panel 43, which is detachably mounted on the outer end face of the bracket 42 by bolts; a sheet 44, three of which are in a group and snap-fitted on the inner end face of the wall panel 43 away from the bracket 42; a convex cabin 45, which is snap-fitted on the sheet 44 located in the middle position; a pressure pipe 46, which is snap-fitted on the middle position of the end of the convex cabin 45 away from the sheet 44; a front brush 47, which is snap-fitted on one of the remaining two sheets 44; a rear brush 48, which is arranged in the space on one side of the front brush 47, and the rear brush 48 and the front brush 47 are distributed on the same sheet 44; a flexible brush 49, which is snap-fitted on the other sheet 44;

[0117] Reference Fig.12 and Fig.13 It can be seen that the front brush 47 and the rear brush 48 are evenly provided with through grooves 411 at the end away from the sheet 44, and the through grooves 411 at one end of the front brush 47 and the through grooves 411 at one end of the rear brush 48 are distributed in an alternating manner, and the outer walls on both sides of the pressure tube 46 are evenly distributed with air valves 412, and the air valve 412 on one side is arranged opposite to the front brush 47 or the rear brush 48, and the air valve 412 on the other side is arranged opposite to the flexible brush 49, and the inner side surface of the wall panel 43 away from the bracket 42 is symmetrically clamped with corner pipes 413, and the inclination angle between the water outlet end of the corner pipe 413 and the front brush 47 is thirty-five degrees, and the outer end surface of the wall panel 43 away from the bracket 42 is rectangularly distributed with water inlet pipes 414 connected with the corner pipes 413, and the outer end surface of the wall panel 43 is clamped with a conduit 415 connected with the water inlet pipe 414.

[0118] Cleaning process of the cleaning unit 4 pair of glue spatulas 374:

[0119] First, the wall plate 43 is controlled by the bracket 42 (the bracket 42 moves stably under the guiding and limiting action of the guide rail 41 or the strip plate 394 at the corresponding position. In specific implementation, the bracket 42 can be driven to reciprocate by the electric slider), and the sheet plate 44 is driven to reciprocate synchronously;

[0120] Next, the front brush 47 and the rear brush 48 are used to scrape and clean the impurities on the end surface of the glue shovel 374, and the turbulence of the fluid sprayed by the corner pipe 413 to the glue shovel 374 area is further increased through the through groove 411 (in specific implementation, the cleaning liquid can be transported to the guide tube 415 through the water inlet pipe 414, and the cleaning liquid in the water inlet pipe 414 can be discharged from the water storage tank 395 through an external hose). Turbulence can promote the mixing degree between the cleaning agent and the cleaned object, enhance the scouring force of the fluid, break the stable boundary layer on the surface of the glue shovel 374, expose and remove the pollutants hidden in the boundary layer, and promote the rapid transfer of pollutants from the surface of the glue shovel 374 to the cleaning medium (such as water flow, air flow), accelerate the cleaning process, and improve the cleaning effect;

[0121] Finally, the rubber shovel 374 is further cleaned by the flexible brush 49. During this process, a certain pressure of gas is continuously delivered to the gas valve 412 through the convex cabin 45 (in specific implementation, the gas can be delivered to the convex cabin 45 through an external pipeline), and is blown to the working area of ​​the front brush 47, the rear brush 48 and the flexible brush 49 through the gas valve 412, so as to further increase the turbulence of the fluid and improve the cleaning effect.

[0122] In addition, the turbulence can ensure its own cleanliness to a certain extent, that is, there is an interactive relationship between the rubber spatula 374 and the front brush 47, the rear brush 48 and the flexible brush 49;

[0123] For cleaning of the rubber spatula 374 in the cylindrical box 38 area:

[0124] When the tooling frame 27 rotates 180 degrees, the end plate 393 drives the strip plate 394 and the cleaning unit 4 to move toward the rubber spatula 374 under the control of the telescopic movable column 392 (the working principle is consistent with the electric telescopic rod 32). After that, the cleaning process of the cleaning unit 4 is completely consistent with the aforementioned working principle.

[0125] When cleaning is completed, the cleaning unit 4 is controlled to return to the initial position by retracting the movable column 392 again.

[0126] The working principle of the biological fermentation device for Chinese herbal medicine provided by the present invention is as follows: Step 1: First, the telescopic gas rod 24 drives the protective frame 25 to move away from the axis of the tank body 11 until the rubber spatula 374 in the cylindrical box 38 area conflicts with the inner wall of the tank body 11, and then the three-phase motor 15 drives the middle column 16 to drive the wide closing ring 23 to rotate;

[0127] Step 2: Then, the rubber spatula 374 in the cylindrical box 38 area is driven by the loading plate 21 to move along the axis direction of the tank body 11 until the horizontal section of the protective frame 25 contacts the inner wall of the tank bottom. After that, the rubber spatula 374 in the corner box 37 area is controlled by the linkage of the electric telescopic rod 32 and the narrow closing ring 31 to perform supplementary cleaning and scraping processing on the inner wall of the tank bottom.

[0128] Step 3: Finally, the front brush 47, the rear brush 48 and the flexible brush 49 continuously make reciprocating motion on the end surface of the rubber shovel 374 under the dual effects of fluid flushing and gas disturbance until the end surface of the rubber shovel 374 is cleaned.

[0129] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0130] The above are only 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.
