Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation tank technology, and in particular to a fermentation tank for producing biological feed. Background Technology
[0002] Biological feed refers to a general term for feed products developed through bioengineering technologies such as fermentation engineering, enzyme engineering, protein engineering, and genetic engineering. It includes fermented feed, enzymatically hydrolyzed feed, microbial-enzyme co-fermented feed, and biological feed additives. Biological feed requires fermentation, and a biological feed fermentation tank is often needed in the process of fermenting biological feed.
[0003] A search revealed that Chinese patent application CN221296860U discloses a biological feed fermentation tank. The main feature is that the top of the fermentation tank body is opened by setting up a feeding component and a fixing component, so that the biological feed can be easily put into the fermentation tank body, making it convenient to add biological feed.
[0004] Compared with existing technologies in related fields, it can be seen that existing fermentation tanks mostly use a fixed stirring mechanism to agitate the feed during the fermentation process. The stirring mechanism is simple, and the fermented material will be layered. The fermented material will accumulate in the dead zone of the stirring, and some materials cannot be stirred and mixed in time, which hinders the flow and contact of materials. As a result, some areas of fermentation are not fully fermented during the fermentation process, which affects the quality of fermentation. Utility Model Content
[0005] The purpose of this invention is to provide a fermentation tank for producing biological feed in order to solve the above-mentioned problems.
[0006] This utility model achieves the above objectives through the following technical solutions:
[0007] A fermenter for producing biological feed includes a vessel body, a discharge valve fixedly installed on the lower surface of the vessel body, a heat preservation unit fixedly installed inside the side wall of the vessel body, and a vessel cover connected to the upper end of the vessel body by bolts. The vessel cover is equipped with a stirring unit, a cleaning unit, a feeding pipe, and an exhaust pipe.
[0008] The stirring unit includes a main shaft, a rotating component, a gear mechanism, and pipe fittings. The main shaft and the rotating component are rotatably mounted on the vessel lid. The main shaft is rotatably mounted at the center of the rotating component. A first rotating power mechanism and a spiral blade are fixedly connected to the main shaft. The upper end of the rotating component is connected to a second rotating power mechanism through the gear mechanism. A sleeve and an air inlet unit are fixedly connected to the rotating component. The sleeve is slidably fitted onto the outside of the spiral blade. An installation cavity is arranged inside the sleeve. The first and second rotating power mechanisms are both fixedly mounted on the vessel lid. The pipe fittings are rotatably arranged on the sleeve. A material feeding plate is fixedly mounted on the pipe fittings. A torque mechanism is sleeved on the part of the pipe fitting located in the installation cavity. The two ends of the torque mechanism are fixedly connected to the pipe fittings and the sleeve.
[0009] Furthermore, a scraper is rotatably mounted at the end of the pipe fitting, and the scraper is slidably connected to the inner wall of the reactor body.
[0010] Furthermore, the sleeve is provided with material guide holes.
[0011] Furthermore, the insulation unit includes an insulation cavity, which is located inside the side wall of the vessel body, and an insulation mechanism is fixedly installed inside the insulation cavity.
[0012] Furthermore, the air intake unit includes an air intake valve seat, an air guide chamber, and a one-way valve. The air intake valve seat is fixedly installed on the vessel cover and is rotatably connected to a rotating component. The air guide chamber is located inside the rotating component. The one-way valve is fixedly arranged on the pipe and is connected to the air intake valve seat through the pipe and the air guide chamber.
[0013] Furthermore, the cleaning unit includes a liquid guide pipe, which is fixedly installed on the lower surface of the vessel lid and located inside the vessel. Universal water spray heads are arranged and fixed on the liquid guide pipe.
[0014] Furthermore, a pressure sensor, a temperature sensor, and a gas concentration sensor are fixedly installed on the vessel lid.
[0015] The advantages compared to existing technologies are as follows:
[0016] 1. The fermented feed is turned and mixed at different angles by rotating the spiral blades, sleeve, and feed-pulling plate. The feed flow and mixing path are increased by the feed guide hole, so that the feed in different positions can fully contact and mix, improve the uniformity of mixing, and effectively improve the efficiency and quality of feed fermentation. The spiral blades and feed-pulling plate can also push the feed in the opposite direction to speed up the discharge efficiency.
[0017] 2. By adjusting the tilt angle of the feed-dispensing plate through the torque mechanism and the resistance of the feed, the feed-dispensing plate can be moved at different angles, which can promote the feed to fully mix and contact, improve the mixing efficiency. At the same time, the torque mechanism makes the pipes, feed-dispensing plate and feed make buffered contact, effectively avoiding damage to the pipes and feed-dispensing plate due to excessive instantaneous force, ensuring the stability and reliability of feed mixing.

[0029] like Figures 1-8 As shown, a biological feed production fermentation tank includes a vessel body 1. A discharge valve 7 is fixedly installed on the lower surface of the vessel body 1. A heat preservation unit is fixedly installed inside the side wall of the vessel body 1. A vessel cover 2 is bolted to the upper end of the vessel body 1. The vessel cover 2 is equipped with a stirring unit, a cleaning unit, a feeding pipe 6, and an exhaust pipe 8. The exhaust pipe 8 is connected to an external waste gas treatment device. The feed to be fermented is added into the vessel body 1, and the vessel body 1 is sealed by the vessel cover 2. The heat preservation unit maintains the fermentation temperature inside the vessel body 1, allowing the feed to ferment better. During the fermentation process, the stirring unit stirs the feed inside the vessel body 1, allowing the feed to come into full contact and mix, which facilitates better fermentation. The waste gas generated during the fermentation process is discharged to the external waste gas treatment device through the exhaust pipe 8 for treatment. During the fermentation process, the feeding pipe 6 facilitates the addition of materials and additives to ensure the normal progress of fermentation. After fermentation, the fermented feed is discharged through the discharge valve 7. After the feed is discharged, the cleaning unit cleans the inside of the vessel body 1, which facilitates the fermentation of feed inside the vessel body 1 again.
[0030] like Figures 1-8As shown, the stirring unit includes a main shaft 302, a rotating component 307, a gear mechanism 306, and a pipe 308. Both the main shaft 302 and the rotating component 307 are rotatably mounted on the vessel cover 2. The main shaft 302 is rotatably mounted at the center of the rotating component 307. A first rotating power mechanism 301 and a spiral blade 303 are fixedly connected to the main shaft 302. The upper end of the rotating component 307 is connected to a second rotating power mechanism 305 via the gear mechanism 306. A sleeve 304 and an air intake unit are fixedly connected to the rotating component 307. The sleeve 304 is slidably fitted onto the outside of the spiral blade 303, and the spiral blade 303 is slidably connected to the inner wall of the sleeve 304. Mounting cavities 310 are arranged inside the sleeve 304. Both the first rotating power mechanism 301 and the second rotating power mechanism 308... Fixedly installed on the lid 2, the pipe fitting 308 is rotatably arranged on the sleeve 304. A material feeding plate 309 is fixedly installed on the pipe fitting 308. A torque mechanism 311 is sleeved on the part of the pipe fitting 308 located in the mounting cavity 310. The two ends of the torque mechanism 311 are fixedly connected to the pipe fitting 308 and the sleeve 304. During the feed fermentation process in the reactor body 1, the first rotary power mechanism 301 drives the main shaft 302 to rotate, and the main shaft 302 drives the spiral blades 303 to rotate. The spiral blades 303 transport the material at the bottom of the reactor body 1 to the top of the reactor body 1, and turn the fermenting feed over during the transport process, so that the fermenting feed can fully contact and mix in the height direction, so that the feed in different positions can participate in the fermentation reaction. At the same time, the second rotary power mechanism... The mechanism 305 drives the rotating component 307 to rotate via the gear mechanism 306. The rotating component 307 drives the sleeve 304 to rotate. The sleeve 304 drives the material-dispensing plate 309 to rotate via the pipe fitting 308. The material-dispensing plate 309 agitates and mixes the fermenting feed. The rotation of the sleeve 304 and the material-dispensing plate 309, in conjunction with the rotation of the spiral blades 303, forms a compound stirring motion within the reactor body 1. This generates stirring forces in both the vertical and horizontal directions, effectively propelling the feed to tumble and mix at different angles within the reactor body 1. This further enhances the contact, mixing, and fermentation of the feed, effectively improving the efficiency and quality of feed fermentation. Simultaneously, the sleeve 304 drives the material-dispensing plate 309 to rotate via the pipe fitting 308. During fermentation, the feeding plate 309 agitates the feed while simultaneously encountering resistance from the feed. A torque mechanism 311 causes the feeding plate 309 to rotate relative to the feed under this resistance, adjusting its tilt angle. Simultaneously, the torque mechanism 311 resets the feeding plate 309, allowing it to agitate the feed at different angles and promote thorough mixing. During this mixing process, the torque mechanism 311 buffers the contact between the pipe 308, the feeding plate 309, and the feed, effectively preventing damage due to excessive instantaneous force and ensuring the stability and reliability of the feed mixing. After fermentation, the opposing rotation of the feeding plate 309 and the spiral blade 303...The fermented feed inside vessel 1 is pushed to facilitate better extraction and improve discharge efficiency.
[0031] like Figure 2 , Figure 6 As shown, a scraper 312 is rotatably mounted on the end of the pipe fitting 308. The scraper 312 is slidably connected to the inner wall of the vessel body 1. During the fermentation of the feed in the vessel body 1, the scraper 312 is rotated along the inner wall of the vessel body 1 by the pipe fitting 308. The scraper 312 can scrape off the feed adhering to the inner wall of the vessel body 1, ensuring that the feed is fully mixed and fermented, and improving the quality of fermentation. At the same time, when discharging, the scraper 312 scrapes off the feed adhering to the inner wall of the vessel body 1, preventing the feed from accumulating on the inner wall of the vessel body 1, reducing feed residue, facilitating the cleaning of the vessel body 1, and reducing waste.
[0032] like Figure 6 As shown, the sleeve 304 is provided with guide holes 313. During the rotation of the sleeve 304, the fermented feed is exchanged inside and outside the sleeve 304 through the guide holes 313, which further increases the flow and mixing path of the feed, so that the feed in different positions can fully contact and mix, and the material can be mixed and fermented more evenly, thereby improving the efficiency and uniformity of fermentation.
[0033] like Figure 2 As shown, the heat preservation unit includes a heat preservation cavity 12, which is located inside the side wall of the vessel body 1. A heat preservation mechanism 13 is fixedly installed inside the heat preservation cavity 12. The heat preservation mechanism 13 is connected to an external heat exchange medium conveying device. During the feed fermentation process, according to the fermentation temperature requirements inside the vessel body 1, the external heat exchange medium conveying device delivers the heat exchange medium to the heat preservation mechanism 13. Heat is exchanged between the heat preservation mechanism 13 and the heat exchange medium inside the vessel body 1 to maintain the stability of the fermentation temperature inside the vessel body 1. The fermentation temperature can be adjusted as needed to ensure the normal progress of fermentation and effectively improve the efficiency and quality of fermentation.
[0034] like Figures 3-5 , Figure 7As shown, the air intake unit includes an air intake valve seat 401, an air guide chamber 402, and a one-way valve 403. The air intake valve seat 401 is fixedly installed on the vessel cover 2 and is rotatably connected to a rotating component 307. The air guide chamber 402 is disposed within the rotating component 307. The one-way valve 403 is fixedly arranged on a pipe 308 and is connected to the air intake valve seat 401 through the pipe 308 and the air guide chamber 402. The air intake valve seat 401 is connected to an external gas supply device. During fermentation, the external gas supply device delivers the gas required for fermentation to the air guide chamber 402 through the air intake valve seat 401, and then delivers it to the one-way valve 403 through the air guide chamber 402 and the pipe 308. 3. Gas is sprayed into the fermenting material. Pipe 308 drives the one-way valve 403 to rotate and stir in the vessel 1, so that the one-way valve 403 can deliver gas to different positions in the vessel 1. During the stirring process, the gas can fully contact and mix with the fermenting feed, providing a sufficient gas supply for the fermentation of the feed, ensuring the normal progress and quality of fermentation. At the same time, the airflow can blow the material, so that the fermenting feed is dispersed and mixed, which facilitates better fermentation and improves the quality of fermentation. During the fermentation ventilation process, the one-way valve 403 can prevent the material in the vessel 1 from flowing back into the pipe 308, ensuring smooth and safe air intake.
[0035] like Figure 2 , Figure 6 As shown, the cleaning unit includes a liquid guide pipe 501, which is fixedly installed on the lower surface of the lid 2 and located inside the vessel body 1. Universal spray nozzles 502 are arranged and fixed on the liquid guide pipe 501. The liquid guide pipe 501 is connected to an external liquid delivery device. After the feed fermentation in the vessel body 1 is completed and discharged, the external liquid delivery device delivers the cleaning liquid into the liquid guide pipe 501 and sprays it out through the universal spray nozzles 502, allowing the cleaning liquid to enter the vessel body 1 and thus rinse the inside of the vessel body 1. Simultaneously, the universal spray nozzles 502 can spray at multiple angles, thereby cleaning the inside of the vessel body 1 from multiple angles and in all directions, effectively removing residual feed and impurities, reducing the workload of manual rinsing, effectively improving the efficiency and quality of cleaning, ensuring the cleanliness of the inside of the vessel body 1, and facilitating further fermentation.
[0036] like Figures 1-3 , Figure 8As shown, a pressure sensor 9, a temperature sensor 10, and a gas concentration sensor 11 are fixedly installed on the lid 2. During fermentation, the pressure sensor 9 monitors the pressure changes inside the vessel 1 in real time, which can detect pressure anomalies caused by fermentation gas production and other reasons, ensuring the safe operation of the equipment. The temperature sensor 10 is used to detect temperature changes inside the vessel 1, and the insulation unit enables precise control of the fermentation temperature inside the vessel 1, meeting the temperature requirements of different fermentation processes and ensuring the normal progress of fermentation. The gas concentration sensor 11 is used to monitor the concentration of specific gases inside the vessel 1, providing data support for gas supply and regulation during fermentation, ensuring that fermenting microorganisms grow and metabolize in a suitable gas environment, and improving fermentation effect and quality.
[0037] Working principle: such as Figure 1 , Figure 2 , Figure 8 As shown, the feed to be fermented is added into the vessel 1, and the vessel 1 is sealed by the lid 2. According to the fermentation temperature requirement inside the vessel 1, the external heat exchange medium conveying device conveys the heat exchange medium to the heat preservation mechanism 13. The heat exchange medium and the heat preservation mechanism 13 exchange heat inside the vessel 1 to maintain the fermentation temperature inside the vessel 1, so that the feed can be fully fermented.
[0038] like Figures 3-5 , Figure 7 As shown, the external gas supply device delivers the gas required for fermentation to the gas delivery chamber 402 through the gas inlet valve seat 401, and then delivers it to the one-way valve 403 through the gas delivery chamber 402 and the pipe fitting 308. The gas is then sprayed out into the fermenting material through the one-way valve 403, providing a sufficient gas supply for the fermentation of the feed.
[0039] like Figures 1-8 As shown, during the feed fermentation process inside the vessel 1, the first rotary power mechanism 301 drives the main shaft 302 to rotate, and the main shaft 302 drives the spiral blades 303 to rotate. The spiral blades 303 transport the material at the bottom of the vessel 1 to the top of the vessel 1, and mix the fermenting feed at multiple angles during the transport process. The second rotary power mechanism 305 drives the rotating component 307 to rotate through the gear mechanism 306. The rotating component 307 drives the sleeve 304 to rotate, and the sleeve 304 drives the material-pulling plate 309 to rotate through the pipe fitting 308. The material-pulling plate 309 moves the fermenting feed. The rotation of the sleeve 304 and the material-pulling plate 309, together with the spiral blades 303, effectively pushes the feed to be turned and mixed at different angles inside the vessel 1, so that the feed can ferment better.
[0040] like Figure 2 , Figures 4-6As shown, during fermentation, the torsion mechanism 311 causes the feeding plate 309 to rotate relative to the feed resistance. The torsion mechanism 311 then resets the feeding plate 309, allowing it to move the feed at different angles. Simultaneously, the pipe 308 drives the scraper 312 to rotate along the inner wall of the vessel 1. The scraper 312 scrapes off the feed adhering to the inner wall of the vessel 1. The feed is then exchanged between the inside and outside of the sleeve 304 through the feed guide hole 313, further increasing the feed flow and mixing path, and ensuring thorough mixing and fermentation of the feed.
[0041] like Figures 1-3 , Figure 8 As shown, during the fermentation process, the pressure sensor 9 monitors the pressure changes inside the vessel 1 in real time to ensure the safe operation of the equipment. The temperature sensor 10 is used to detect the temperature changes inside the vessel 1, which facilitates the adjustment of the fermentation temperature. The gas concentration sensor 11 is used to monitor the concentration of a specific gas inside the vessel 1, providing data support for gas supply and control during the fermentation process and ensuring the normal progress of fermentation.
[0042] like Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown, the first rotary power mechanism 301 drives the spiral blade 303 to rotate in the opposite direction, and the second rotary power mechanism 305 drives the feeding plate 309 to rotate in the opposite direction. The reverse rotation of the feeding plate 309 and the spiral blade 303 pushes the fermented feed in the kettle body 1, so that the fermented feed is discharged through the discharge valve 7.
[0043] like Figure 2 , Figure 6 As shown, after the fermented feed is discharged, the external infusion device delivers the cleaning liquid into the infusion pipe 501 and sprays it out through the universal spray head 502, so that the cleaning liquid enters the vessel body 1 from multiple angles, thereby rinsing the inside of the vessel body 1.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
