Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, specifically to a feeding mechanism and a Clostridium butyricum fermentation tank. Background Technology

[0002] Clostridium butyricum is an obligate anaerobic, Gram-positive spore-forming bacillus, resistant to gastric acid and bile salts, allowing it to easily pass through the animal digestive tract and colonize and multiply in the cecum and colon. Clostridium butyricum not only regulates the intestinal microecology by producing organic acids such as butyric acid and acetic acid, lowering intestinal pH and inhibiting harmful bacteria such as Escherichia coli and Salmonella, but also promotes the proliferation of beneficial bacteria such as Bifidobacteria and Lactobacillus. Furthermore, it enhances intestinal barrier function by increasing mucosal thickness and tight junction protein expression, reducing pathogen invasion. It also stimulates immune cells to secrete anti-inflammatory factors, reducing the concentration of inflammatory factors in the body and alleviating enteritis. In livestock, poultry, and aquaculture, Clostridium butyricum can replace antibiotics because it can break down macromolecular nutrients in feed, improving digestibility and synthesizing essential amino acids and vitamins, thereby significantly improving feed utilization and production performance.

[0003] Patent CN213388626U discloses a Clostridium butyricum fermenter with a feeding device. The fermenter includes a tank body with a top opening, a top cover mounted on the top opening, a heating device mounted on the bottom of the tank body, and a transport device mounted on the outside of the tank body. A guide rail is axially arranged on the outer surface of the tank body, and the transport device slides up and down along the guide rail. The transport device includes a guide seat, a storage cylinder hinged to the guide seat, and a drive cylinder mounted on the ground. The guide seat is movably engaged on the guide rail, and the drive cylinder can drive the guide seat to move up and down. A first cylinder is also hinged between the outer side of the guide seat and the storage cylinder. Material is first loaded into the storage cylinder. The drive cylinder drives the guide seat to move up and down, and the storage cylinder moves upward following the guide seat. The first cylinder can then drive the storage cylinder to flip, allowing the material in the storage cylinder to be poured into the tank body. This method saves a significant amount of manpower and has high feeding efficiency.

[0004] Although the above-mentioned device has a relatively high feeding efficiency, it still has the following shortcomings: Clostridium butyricum requires an anaerobic environment throughout the fermentation process; oxygen directly inhibits bacterial growth and can even lead to fermentation failure. However, the aforementioned device has an open top, and the material storage cylinder inevitably comes into contact with air when it is turned over to pour the material. Furthermore, there is no gas protection design, meaning that oxygen is introduced into the fermenter during the pouring process, disrupting the anaerobic fermentation environment and affecting the fermentation production of Clostridium butyricum. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism and a Clostridium butyricum fermentation tank, which allows for the anaerobic addition of raw materials during the Clostridium butyricum fermentation process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism, comprising four flow valves disposed on the outside of the fermenter body, the flow valves being connected to a feeding pump, the feeding pump being connected to a feeding box, an air inlet pump and an air outlet pump being symmetrically disposed on the top surface of the feeding box, the air inlet pump being connected to an air inlet regulating box via an air inlet pipe, the air outlet pump being connected to an air outlet regulating box via an air outlet pipe, a nitrogen output bottle and a nitrogen return bottle being disposed on the ground, the air inlet regulating box being connected to the nitrogen output bottle, the air outlet regulating box being connected to the nitrogen return bottle, and a gas composition detector being disposed on the upper outside of the feeding box.

[0007] Furthermore, the bottom of the feeding box is equipped with an installation base that is suspended from the roof of the factory building.

[0008] Furthermore, the feed pump and flow valve are fixedly connected via a flange.

[0009] Furthermore, observation windows are symmetrically arranged on the left and right sides of the feeding box.

[0010] Furthermore, material information nameplates are installed on both the left and right sides of the feeding box, located above the observation window.

[0011] Furthermore, both the intake and exhaust regulating boxes have gas flow direction indicators on their top surfaces.

[0012] Furthermore, a Clostridium butyricum fermenter includes a fermenter body and a feeding mechanism as described in any one of the above.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By setting up four sets of flow valves, feeding pumps, and feeding tanks, each set of devices can independently control the start, stop, and flow rate of conveying a single material, achieving precise proportioning and quantitative conveying of multiple materials. An inlet pump introduces nitrogen to expel air from the feeding tank, while an outlet pump recovers nitrogen containing a small amount of oxygen to a reflux bottle. Combined with a gas composition detector, the oxygen content inside the tank is monitored in real time, ensuring an oxygen-free environment throughout the feeding process. A mounting base suspended from the factory roof is placed on the bottom of the feeding tank, avoiding the occupation of ground space and providing stable support. Using flanges to fix the feeding pump and flow valves ensures a stronger seal, preventing material leakage. An observation window allows for direct viewing of the remaining material and its form without opening the feeding tank, enabling real-time monitoring of the feeding progress and preventing the introduction of oxygen. A material information nameplate indicates the type of material in the feeding tank, preventing feeding errors due to human misjudgment. Gas flow direction indicators clearly mark the direction of nitrogen input and output, preventing reverse connection errors during pipeline installation. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figures 1 to 3 As shown, a feeding mechanism includes four flow valves 2 disposed on the outside of the fermenter body 1. The flow valves 2 are connected to a feeding pump 3, and the feeding pump 3 is connected to a feeding box 4. An air inlet pump 401 and an air outlet pump 402 are symmetrically disposed on the top surface of the feeding box 4. The air inlet pump 401 is connected to an air inlet regulating box 5 through an air inlet pipe 403, and the air outlet pump 402 is connected to an air outlet regulating box 6 through an air outlet pipe 404. A nitrogen output bottle 7 and a nitrogen return bottle 8 are disposed on the ground. The air inlet regulating box 5 is connected to the nitrogen output bottle 7, and the air outlet regulating box 6 is connected to the nitrogen return bottle 8. A gas composition detector 405 is disposed on the upper outside of the feeding box 4.

[0018] like Figure 1 As shown, the fermenter in this utility model is structurally similar to existing fermenters. For example, patent CN213388626U discloses a Clostridium butyricum fermenter with a feeding device. The main improvement of this utility model is that it allows for anaerobic addition of raw materials during the Clostridium butyricum fermentation process. Figures 1 to 3 As shown, in this utility model, a feeding mechanism and Clostridium butyricum fermenter are described. Before fermentation begins, various auxiliary raw materials such as carbon sources and nitrogen sources are first loaded into the corresponding feeding boxes 4. Then, the air inlet pump 401 is started. Nitrogen in the nitrogen output bottle 7 is stabilized by the air inlet regulating box 5 and injected into the feeding box 4 through the air inlet pipe 404. At the same time, the air outlet pump 402 is turned on to discharge the original air in the feeding box 4 into the nitrogen return bottle 8 for recovery through the air outlet pipe 403 and the air outlet regulating box 6. The gas composition detector 405 monitors the oxygen content in the feeding box 4 in real time until the oxygen concentration drops to the allowable range for Clostridium butyricum fermentation, forming a stable anaerobic environment.

[0019] During the fermentation process of Clostridium butyricum, when staff need to add various auxiliary materials to the tank, they can start the corresponding material feeding pump 3 according to the fermentation requirements. The anaerobic raw materials in the feeding box 4 are then transported to the fermentation tank body 1 through the pipe sealed by the flange 10. Four flow valves 2 independently control the flow rate of different raw materials, ensuring that various auxiliary materials are added synchronously or in stages according to the specified ratio. During the transportation process, the air inlet pump 401 continuously replenishes nitrogen, and the air outlet pump 402 assists in recovery, maintaining a slight positive pressure inside the feeding box 4 to prevent backflow of outside air.

[0020] like Figure 1 and Figure 3 As shown, the bottom of the feeding box 4 is equipped with an installation base 9 that is suspended from the roof of the factory building.

[0021] Specifically, by installing a mounting base 9 on the bottom of the feeding box 4 and suspending it from the factory roof, a stable support can be provided for the feeding box 4, ensuring that the feeding box 4 is placed stably when the machine is working. In addition, the suspended mounting base 9 can avoid occupying ground space, making the position of the feeding box 4 fixed and away from ground interference, facilitating connection with the pipeline of the fermentation tank body 1, and reducing the obstruction of the feeding operation by ground equipment.

[0022] like Figures 1 to 3 As shown, the feed pump 3 and the flow valve 2 are fixedly connected by the flange 10.

[0023] Specifically, by fixing the feed pump 3 and the flow valve 2 together via flange 10, the sealing performance is stronger than that of ordinary pipe connections, which can prevent material leakage. Furthermore, the flange 10 is fixed with bolts, which can be quickly disassembled and assembled without complicated tools during later maintenance, reducing maintenance costs and downtime.

[0024] like Figure 2 and Figure 3 As shown, observation windows 406 are symmetrically arranged on the left and right sides of the feeding box 4.

[0025] Specifically, by symmetrically setting observation windows 406 on the left and right sides of the feeding box 4, the remaining amount and form of the material in the box can be viewed intuitively without opening the feeding box 4, and the feeding progress can be monitored in real time. In addition, it can reduce the risk of anaerobic environment damage caused by opening the lid to check, and avoid pollution that may be caused by manual contact with the material.

[0026] like Figure 2 and Figure 3 As shown, material information nameplates 407 are provided on both the left and right sides of the feeding box 4, located above the observation window 406.

[0027] Specifically, by setting a material information nameplate 407 above the observation window 406, the types of materials in the feeding box 4 can be marked. When multiple materials are fed in parallel, different materials can be quickly distinguished, avoiding feeding errors caused by human misjudgment.

[0028] like Figure 1 and Figure 2 As shown, the top surfaces of the intake regulating box 5 and the exhaust regulating box 6 are equipped with gas flow direction indicators 11.

[0029] Specifically, by setting gas flow direction indicators 11 on the top surfaces of the inlet regulating box 5 and the outlet regulating box 6, the flow direction of nitrogen input and output can be clearly marked, avoiding reverse errors when connecting pipelines.

[0030] like Figure 1 As shown, a Clostridium butyricum fermenter includes a fermenter body 1 and a feeding mechanism as described in any one of the above.

[0031] Specifically, the feeding mechanism, specifically designed for anaerobic fermentation, is integrated with the fermenter body 1, eliminating the need for significant modifications to the fermenter and reducing equipment upgrade costs for enterprises. It also retains the original advantages of the fermenter body 1, directly adapting to the strictly anaerobic and nutrient-sensitive characteristics of Clostridium butyricum, thus improving fermentation stability and product yield and consistency.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
