Description

Technical Field

[0001] This invention relates to the field of bio-fermentation equipment technology, specifically to a fermentation device for by-products after primary processing of traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to plants derived from nature, mostly green and natural herbaceous plants. These plants are not only rich in nutrients and bioactive components, but also have low drug residues, are naturally pollution-free, and are environmentally friendly. Furthermore, byproducts of TCM can be fermented and transformed into valuable resources through thorough mixing with microbial preparations. Their use is of great significance for the development of safe and green energy.

[0003] In order to ensure the fermentation effect, current fermentation devices for by-products after primary processing of Chinese herbal medicines often introduce external gases such as air and nitrogen. This can interfere with the fermentation system and increase the investment and operating costs of supporting gas supply equipment. At the same time, existing fermentation devices for by-products of Chinese herbal medicines adopt an open sampling structure with flange handholes, simple flip-tops, and ordinary ball valves. Opening the cover can easily introduce airborne bacteria that can destroy the pure culture fermentation system and interfere with the fermentation process. Furthermore, open operation can easily cause the dregs of herbs to scatter, increasing the amount of on-site cleaning and raw material loss.

[0004] To address the above issues, a fermentation device for byproducts after the initial processing of traditional Chinese medicine is proposed. Summary of the Invention

[0007] Furthermore, the ventilation mechanism includes a ventilation pipe fixedly disposed in the middle of the inner side of the stirring shaft, and a rotary pipe joint is installed at the top of the ventilation pipe, and an air inlet pipe is installed at the top of the rotary pipe joint.

[0008] Furthermore, a control valve is installed at the bottom of the vent pipe, and an outlet pipe is connected to the lower side of the vent pipe, and the outlet pipe is located inside the stirring blade.

[0009] Furthermore, the sampling mechanism includes a guide frame disposed inside one side of the stirring shaft, with one bottom end of the guide frame extending outside the stirring shaft. A sliding plate two is attached to the upper surface of the guide frame, and the sliding plate two is slidably disposed on the stirring shaft. An inclined block two is fixed to one side of the top of the sliding plate two, and a spring three is fixed to the lower side of one side of the inclined block two. The inclined block two and the sliding plate two are elastically connected to the stirring shaft through the spring three.

[0010] Furthermore, a collection box is provided on one side of the inside of the guide frame, and an electromagnetic block is provided on one side of the collection box, and the electromagnetic block is fixed on the guide frame.

[0011] Furthermore, a screw cap is threaded onto the top of the guide frame, an electromagnetic block two is installed inside the lower part of the guide frame, the rotating sleeve includes a fixed frame disposed inside the stirring shaft and the fixed frame is fixedly connected to the rotating sleeve, an extrusion head is fixedly fixed on one side of the fixed frame, and an extrusion plate is elastically installed on the lower surface of the sliding plate two.

[0012] Furthermore, the conduction mechanism includes an inner conductive seat fixed to the top of the stirring shaft, and an outer conductive seat is rotatably mounted on the outside of the inner conductive seat. A support frame is fixed to the lower outside of the outer conductive seat and the support frame is fixed to the gearbox. A conductive wire is connected inside the inner conductive seat.

[0013] Furthermore, the stirring blade includes an inclined block 1 disposed inside the stirring shaft, and a sliding plate 1 is fixed on one side below the inclined block 1. The sliding plate 1 can slide radially within an arc groove opened on the surface of the stirring shaft, and the sliding plate 1 can slide left and right on the stirring blade.

[0014] Furthermore, a spring is fixed below one side of the inclined block, and the inclined block and the sliding plate are elastically connected to the stirring shaft through the spring. A spring is fixed inside the sliding plate, and a sealing head is fixed below the spring.

[0015] Furthermore, the sealing head is provided with an air outlet on its exterior, and several sets of air outlets are provided on the stirring blade. Under normal conditions, each set of air outlets is provided with a sealing head inside. A pressure rod is provided on one side of the inclined block, and the pressure rod is fixed on the stirring shaft.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The device of this invention connects the ventilation mechanism to the biogas produced by the fermentation tank, eliminating the need to purchase external gas supply equipment such as air and nitrogen, thus significantly reducing the investment in supporting equipment and operating energy consumption. The biogas is released evenly as the stirring blades rotate, which can not only break up the floating slag and hard shell of Chinese medicine residue with the help of airflow and eliminate the accumulation of bottom sediment, but also assist mechanical stirring to reduce blade wear. It can also release the biogas trapped inside the material, balance the gas distribution in the tank, improve the degradation efficiency of Chinese medicine by-products and biogas output, and ensure that no external impurities disrupt the pure fermentation environment throughout the process.

[0017] 2. The sampling component of this invention is integrated inside the hollow stirring shaft, eliminating the need to open the fermentation tank throughout the process. This maintains a sterile and sealed fermentation environment inside the tank, preventing the introduction of external airborne bacteria that could interfere with the fermentation process. Sampling is achieved by using biogas pressure to push the collection box for quantitative sampling. No medicinal residue is scattered during operation, reducing on-site cleaning workload and raw material loss. There is no need for manual shoveling of material into the tank, significantly reducing the labor intensity of operators. This invention is suitable for the production requirements of high-purity pure-culture fermentation of traditional Chinese medicine by-products. After sampling, the collection box can be easily removed and replaced by unscrewing the cap at the top of the stirring shaft. The reset process is simple, and multiple sampling tests can be performed continuously.

[0018] 3. The air outlet of the stirring blade of this invention is equipped with an automatic sealing structure. During conventional fermentation and stirring, the sealing head closes the air hole to prevent the residue from clogging the pipeline. The air outlet is opened synchronously only during the gas introduction and sampling conditions to ensure the long-term stable flow of the gas supply pipeline. At the same time, a set of power motors synchronously drives the entire set of stirring, gas supply and sampling operations. The equipment has a compact structure and does not require the addition of multiple independent drive devices, which reduces the equipment manufacturing cost and control difficulty.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To address the technical problems of introducing external gases into fermentation equipment during operation, which can interfere with the fermentation system and increase costs, such as... Figures 1-5 As shown, the following preferred technical solutions are provided: A fermentation device for by-products after primary processing of traditional Chinese medicine includes a fermentation tank 1 and a feeding cover 2 installed on one side of the fermentation tank 1. The feeding cover 2 is sealed to the feeding port on the fermentation tank 1 via a flange. By opening the feeding cover 2, the by-products after primary processing of traditional Chinese medicine and microbial preparations can be added to the fermentation tank 1 for biological fermentation. This allows the by-products after primary processing of traditional Chinese medicine to be converted into recyclable substances through fermentation. An exhaust pipe 30 is connected to the upper side of the fermentation tank 1. The exhaust pipe 30 allows the biogas produced during fermentation in the fermentation tank 1 to be released, thereby depressurizing the fermentation tank 1. A discharge valve 20 is installed in the lower middle part of the fermentation tank 1. The fermented material in the fermentation tank 1 can be discharged through the discharge valve 20. A power motor 3 is installed on the top of the fermentation tank 1, and a gearbox 4 is installed at the output end of the power motor 3. A stirring shaft 5 is rotatably installed in the middle of the gearbox 4. The stirring shaft 5 has a hollow structure and is sealed and rotatably connected to the fermentation tank 1. The servo-type power motor 3 is controlled by an external control device based on existing principles, which is not shown in the figure. The power motor 3 and the gearbox 4 can drive the stirring shaft 5 to rotate inside the fermentation tank 1.

[0023] A rotating sleeve 6 is installed in the middle of the surface of the stirring shaft 5, and stirring blades 7 are fixed on both sides of the rotating sleeve 6. When the stirring shaft 5 is driven to rotate counterclockwise by the power motor 3, it can synchronously drive the rotating sleeve 6 and the stirring blades 7 to rotate together, so that the stirring blades 7 can stir counterclockwise in the fermentation tank 1. This can break the stratification phenomenon of scum crusting and bottom sediment accumulation in the fermentation system of traditional Chinese medicine by-products, so that the materials, inoculum, and nutrient substrate are fully mixed, the temperature in the tank is balanced and the scaling of the heat exchange tube wall is reduced. At the same time, the biogas trapped in the materials is released in time, and the locally accumulated biogas is diluted to avoid local acidification that inhibits the fermentation community. At the same time, the stirring mixes the trace amount of residual oxygen in the tank and evenly releases hydrogen sulfide gas, thereby improving the degradation efficiency of traditional Chinese medicine residue and biogas yield.

[0024] A ventilation mechanism 8 is provided in the middle of the stirring shaft 5, and a transmission mechanism 10 is installed at the top of the stirring shaft 5. The transmission mechanism 10 is equipped with an existing conductive slip ring structure, which allows external electrical energy to be transmitted to the rotating stirring shaft 5, so that the electrical energy can be used by the subsequent structure inside the stirring shaft 5 for subsequent gas supply and sampling operations. The ventilation mechanism 8 is connected to the stirring blades 7. The input end of the ventilation mechanism 8 is connected to the collection end of the biogas produced by the device, which can introduce the biogas produced by the device into the stirring blades 7. The biogas introduced by the ventilation mechanism 8 can enter the rotating stirring blades 7, so that the introduced biogas can be released into the fermentation tank 1 while being stirred by the stirring blades 7. In this way, the circulating airflow disturbs the material, which can break the scum and hard shell formed by the by-products of Chinese herbal medicine, disperse the bottom sediment, assist mechanical stirring to reduce equipment wear and energy consumption, and bring out the biogas wrapped in the material to improve the gas production and release efficiency. At the same time, the gas introduced by circulation is released with the rotating stirring blades 7, which can make the introduced gas more evenly dispersed, which is conducive to improving the fermentation effect more efficiently.

[0025] A sampling mechanism 9 is installed on one side of the inside of the stirring shaft 5. Existing fermentation devices for traditional Chinese medicine by-products adopt an open sampling structure with flange handholes, simple flip-tops, and ordinary ball valves. However, opening the cover can easily introduce airborne bacteria that can damage the pure fermentation system and interfere with the fermentation process. Furthermore, open operation can easily cause the dregs to scatter, increasing the amount of on-site cleaning and raw material loss. The sampling mechanism 9 can work in conjunction with the biogas introduced by the ventilation mechanism 8, so that the sampling mechanism 9 can achieve closed, sterile, and quantitative sampling from the fermentation tank 1 under the action of the introduced air pressure. This prevents external bacteria from contaminating the fermentation inside the fermentation tank 1, which meets the requirements of high-purity fermentation production of traditional Chinese medicine by-products. At the same time, the operation steps are simplified, eliminating the need for manual shoveling into the tank, reducing the labor intensity of personnel, and also helping to ensure the cleanliness of the equipment site.

[0026] like Figure 3As shown, the ventilation mechanism 8 includes a ventilation pipe 81 fixedly installed in the middle of the inner side of the stirring shaft 5. The ventilation pipe 81 is a corrosion-resistant flexible hose, and a rotary pipe joint 82 is installed on the top of the ventilation pipe 81. The vertical center line of the rotary pipe joint 82 coincides with the vertical center line of the stirring shaft 5. An air inlet pipe 83 is installed on the top of the rotary pipe joint 82. The input end of the air inlet pipe 83 is connected to the collection end of the self-generated biogas outside the device, which can introduce the biogas generated by the device into the ventilation pipe 81. At the same time, the rotary pipe joint 82 can realize the air supply of the ventilation pipe 81 and the air inlet pipe 83 in the rotating state, so that the airflow can be introduced into the ventilation pipe 81 that rotates with the stirring shaft 5.

[0027] A control valve 84 is installed at the bottom of the vent pipe 81. The control valve 84 is a solenoid valve, which is also controlled by external control equipment. A gas outlet pipe 85 is connected to the lower side of the vent pipe 81 and is located inside the stirring blade 7. The stirring blade 7 on one side of the rotating sleeve 6 is hollow, so that the biogas introduced into the vent pipe 81 can pass through the gas outlet pipe 85 into the hollow stirring blade 7. Finally, the introduced biogas is discharged from the bottom surface of the stirring blade 7 into the fermentation tank 1. In this way, the introduced biogas disturbs the material, which can break down the by-products of Chinese herbal medicine. The resulting scum crust breaks up the bottom sediment and reduces equipment wear and energy consumption through mechanical stirring of the auxiliary stirring blades 7. It also brings out the biogas trapped in the material, improving the gas production and release efficiency. At the same time, the gas introduced in circulation is released by the stirring blades 7 rotating counterclockwise in the fermentation tank 1, which can make the introduced gas more evenly dispersed, which is conducive to improving the fermentation effect more efficiently. In addition, the introduced biogas comes from the biogas produced by the device itself, without the need to introduce external gases such as air and nitrogen. There are no external impurities interfering with the fermentation system, which helps to reduce the investment and operating costs of supporting gas supply equipment.

[0028] To address the technical issues of open sampling, which can easily disrupt the pure culture fermentation system and increase operational complexity and raw material loss, such as... Figures 1-7 As shown, the following preferred technical solutions are provided: like Figure 6 and Figure 7As shown, the sampling mechanism 9 includes a guide frame 91 disposed inside one side of the stirring shaft 5. The guide frame 91 is inverted L-shaped, and one bottom end of the guide frame 91 extends outside the stirring shaft 5. A sliding plate 93 is attached to the upper surface of the guide frame 91 and is slidably disposed on the stirring shaft 5. An inclined block 92 is fixed to one side of the top of the sliding plate 93. The right side of the inclined block 92 is an inclined surface that slopes towards the center of the stirring shaft 5. A spring 94 is fixed below one side of the inclined block 92. The inclined block 92 and the sliding plate 93 are elastically connected to the stirring shaft 5 through the spring 94. The sliding plate 93 can slide elastically on the guide frame 91 and the stirring shaft 5 through the spring 94. The sliding plate 93 and the stirring shaft 5 are provided with a sliding seal, so that when the sliding plate 93 slides through the stirring shaft 5, the material in the fermenter 1 will not enter the stirring shaft 5.

[0029] A collection box 96 is provided on one side of the inside of the guide rack 91. An electromagnetic block 97 is provided on one side of the collection box 96. The electromagnetic block 97 is an electromagnetic coil that can generate magnetic attraction when energized. The electromagnetic block 97 is fixed on the guide rack 91. The lower left side of the collection box 96 is inclined so that it can be pushed by the airflow during subsequent inflation. A magnet is provided inside the left side of the collection box 96. Under normal conditions, when the electromagnetic block 97 is energized, it will attract the magnet provided inside the left side of the collection box 96, so that the position of the collection box 96 is fixed inside the guide rack 91. At this time, the collection box 96 just coincides with the opening on the guide rack 91, and the edge of the collection box 96 can just seal the edge of the opening on the guide rack 91, preventing material from entering the guide rack 91. The opening is exposed inside the fermentation tank 1. At this time, the material in the fermentation tank 1 will enter the collection box 96, and can be collected and sampled inside the collection box 96.

[0030] like Figure 5 As shown, the top of the guide frame 91 is threaded with a screw cap 98. The top of the guide frame 91 extends above the outside of the stirring shaft 5. An electromagnetic block 99 is installed inside the lower part of the guide frame 91. The electromagnetic block 99 is also an electromagnetic coil that can generate magnetic attraction when energized. A magnet is also provided at the bottom of the collection box 96. When the collection box 96 moves onto the electromagnetic block 99, the electromagnetic block 99 is energized and will generate a repulsive force on the magnet at the bottom of the collection box 96, so that the collection box 96 will be pushed upward. The rotating sleeve 6 includes a fixed frame 61 set inside the stirring shaft 5, and the fixed frame 61 is fixedly connected to the rotating sleeve 6. The rotating sleeve 6 and the fixed frame 61 can slide in the arc groove opened on the surface of the stirring shaft 5. An extrusion head 62 is fixed on one side of the fixed frame 61.

[0031] When sampling is required, the power motor 3 drives the stirring shaft 5 to rotate clockwise. At this time, under the resistance of the solid material in the fermentation tank 1, the rotating sleeve 6 and the fixed frame 61 will rotate counterclockwise relative to the stirring shaft 5, allowing the fixed frame 61 to slide counterclockwise on the groove opened on the stirring shaft 5. This causes the extrusion head 62 to press the inclined block 92 along the right inclined surface of the inclined block 92, causing the inclined block 92 and the sliding plate 93 to move to the left and compress the spring 94. The lower surface of the sliding plate 93 is elastically fitted with an extrusion plate 95, which utilizes... A spring is installed on the sliding plate 93. When the sliding plate 93 is moved to the left, the extrusion plate 95 will elastically press down and finally completely seal the opening on the guide frame 91 to prevent leakage. The extrusion plate 95 will also press the material downward into the collection box 96 to prevent the material from being exposed on the outside of the collection box 96 and easily falling off and contaminating it during subsequent movement. At the same time, the right side of the extrusion plate 95 and the right edge of the opening on the guide frame 91 are both inclined surfaces, which makes it easy for the extrusion plate 95 to be removed from the opening on the guide frame 91 and reset.

[0032] At this point, after the extrusion plate 95 is sealed, the control valve 84 opens, causing the introduced biogas to be diverted to the left side of the guide frame 91. The outer surface of the collection box 96 is slidably sealed to the inner surface of the guide frame 91. As gas continuously fills the guide frame 91, the first electromagnetic block 97 is de-energized, causing the gas pressure to push the collection box 96 to the right. When the collection box 96 moves onto the second electromagnetic block 99, it is magnetically pushed upwards along the guide frame 91. Under the continuous influx of gas pressure, the collection box 96 containing fermented material is eventually pushed to the top of the guide frame 91. Finally, the control valve 84... 4. Close the lid to stabilize the air pressure inside the feeder 91. Finally, open and twist the cover 98 to remove the collection box 96. This completes the process of using the biogas to push the collection box 96 while keeping the fermentation tank 1 sealed, without opening it. This allows for closed, sterile, and quantitative sampling without external bacteria contaminating the fermentation inside the fermentation tank 1. This meets the requirements for high-purity fermentation production of traditional Chinese medicine by-products. At the same time, the operation steps are simplified, eliminating the need for manual shoveling of materials into the tank, reducing labor intensity, and also helping to ensure the cleanliness of the equipment site.

[0033] Simultaneously, after sampling, with no airflow or external air pressure in the vent pipe 81, the clean collection box 96 is placed back into the guide rack 91. The collection box 96 falls under gravity, and the electromagnetic block 97 is energized to attract the collection box 96 to the left, so that the collection box 96 returns to the opening below the guide rack 91 for the next sampling. At the same time, when the stirring shaft 5 rotates clockwise, the sliding plate 93 and the extrusion plate 95 will be pushed back by the spring 94, causing the sliding plate 93 to move to the right and reset, opening the opening on the guide rack 91.

[0034] like Figure 5As shown, the conduction mechanism 10 includes an inner conductive seat 101 fixed to the top of the stirring shaft 5, and an outer conductive seat 102 rotatably mounted on the outside of the inner conductive seat 101. A support frame 103 is fixed to the lower outside of the outer conductive seat 102 and is fixed on the gearbox 4. A conductive wire 104 is connected inside the inner conductive seat 101, and a brush is provided between the outer conductive seat 102 and the inner conductive seat 101, forming a conductive slip ring structure of the existing principle. This allows the current introduced outside the outer conductive seat 102 to be transmitted to the conductive wire 104, so that the conductive wire 104 can supply power to the control valve 84, the first electromagnetic block 97, and the second electromagnetic block 99.

[0035] To address the technical problem of pore blockage during idle periods of induced draft, such as... Figures 2-8 As shown, the following preferred technical solutions are provided: like Figure 6 and Figure 8 As shown, the stirring blade 7 includes an inclined block 71 disposed inside the stirring shaft 5. The right side surface of the inclined block 71 is an inclined surface that is inclined toward the center of the stirring shaft 5. A sliding plate 72 is fixed on the lower side of the inclined block 71. The sliding plate 72 can slide radially in the arc groove opened on the surface of the stirring shaft 5, and the sliding plate 72 can slide left and right on the stirring blade 7.

[0036] A spring 73 is fixed below one side of the inclined block 71, and the inclined block 71 and the sliding plate 72 are elastically connected to the stirring shaft 5 through the spring 73. A spring 74 is fixed inside the sliding plate 72, and a sealing head 75 is fixed below the spring 74.

[0037] The sealing head 75 is provided with an air outlet 76 on the outside, and several sets of air outlets 76 are provided on the stirring blade 7. Under normal conditions, each set of air outlets 76 is provided with a sealing head 75 inside. A pressure rod 40 is provided on one side of the inclined block 71, and the pressure rod 40 is fixed on the stirring shaft 5.

[0038] As described above, when the stirring shaft 5 rotates clockwise, causing the rotating sleeve 6 and the fixed frame 61 to rotate counterclockwise relative to the stirring shaft 5, the sliding plate 72 can slide counterclockwise on the groove opened on the stirring shaft 5, causing the inclined block 71 to slide counterclockwise along the pressure rod 40. This causes the inclined block 71 to gradually lose the pressure of the pressure rod 40 and release the compressed spring 73. At this time, under the extension force of the spring 73, the sliding plate 72 will move to the right, causing the sealing head 75 to slide out of the air outlet 76 and compress the spring 74. At this time, the air outlet 76 will open, allowing the airflow that has filled the stirring blade 7 to be released from the air outlet 76. Inside the fermentation tank 1, the above-mentioned effects are achieved. At the same time, when the stirring shaft 5 rotates counterclockwise normally, the air outlet 76 is in a closed state, which avoids the problem of impurities in the fermentation tank 1 clogging the air outlet 76 and entering the stirring blade 7 when not priming gas. This ensures the stability and safety of the device during normal fermentation. After priming gas, the stirring shaft 5 changes from clockwise to counterclockwise rotation, and the inclined block 71 will be pressed again by the pressing rod 40 to compress the spring 73, so that the sealing head 75 is inserted into the air outlet 76. Thus, when gas needs to be introduced or samples need to be taken, the stirring shaft 5 only needs to be rotated clockwise to carry out the above work, which can ensure the synchronization of work.
