Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation technology, specifically a sugar supplementation device for a microbial fermentation tank. Background Technology

[0002] In the inoculum preparation stage, the inoculum needs to be placed in a fermenter for cultivation. During fermentation, microorganisms continuously consume carbon sources such as sugars, causing the carbon source concentration in the tank to gradually decrease. To precisely control the carbon source supply and meet the needs of microbial growth, metabolism, and the synthesis of target products, sugar supplementation is required during fermentation. Currently, the industry generally uses specialized sugar supplementation equipment to improve fermentation efficiency, product yield, and overall economics by scientifically controlling the amount and timing of sugar supplementation.

[0003] As per existing technology, patent CN218989270U discloses a sugar supplementation device, including a sugar storage tank, a sugar supplementation tank, and a fermentation tank. The sugar storage tank and the sugar supplementation tank are connected by a sugar inlet pipe. One end of the sugar inlet pipe extends horizontally into the sugar supplementation tank and has a sugar outlet. A quantitative switch assembly is provided in the horizontally extended end of the sugar inlet pipe. The quantitative switch assembly includes a sealing plug, a connecting plate, a drive rod, and a floating ball. A fixing rod is fixed on the sealing plug, and the fixing rod has a groove. An elongated hole is provided on the bottom wall of the sugar inlet pipe. A corresponding locking component is provided on the connecting plate. The drive rod is connected to the connecting plate, and the floating ball is connected to the connecting plate. This sugar supplementation device can quantitatively supplement sugar to the fermentation tank during Clostridium butyricum fermentation, and the amount of sugar supplementation can be adjusted according to the sugar supplementation requirements. It is convenient to use, low in cost, accurate in measurement, and reliable in performance, greatly reducing labor intensity and labor costs, and ensuring the normal progress of fermentation.

[0004] The aforementioned sugar replenishment device still has certain shortcomings: Although the aforementioned sugar replenishment device can adjust the amount of sugar replenished according to demand, is convenient to use, and is inexpensive, it still has drawbacks. During long-term operation, sugar syrup gradually adheres to the surface of the internal floating ball. In particular, the sugar syrup at the top of the floating ball will form a hard sugar shell due to water evaporation during intermittent operation. The accumulation of this sugar shell significantly increases the overall weight of the floating ball, reducing its actual displaced liquid volume and thus altering buoyancy. This change directly affects the accuracy of the floating ball's liquid level sensing, ultimately leading to a decrease in the metering accuracy of the sugar replenishment device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sugar replenishment device for microbial fermentation tanks, which makes the metering accuracy of the main body of the sugar replenishment tank less prone to decline.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sugar-supplementing device for a microbial fermentation tank, comprising a sugar-supplementing tank body, a feed pipe fixedly connected to one side of the top of the sugar-supplementing tank body, a connecting pipe fixedly connected to the lower end of the sugar-supplementing tank body near the feed pipe, a connecting bend connected to the end of the connecting pipe away from the sugar-supplementing tank body, an elastic membrane fixedly connected inside the connecting bend, a water storage pipe connected to the end of the connecting bend away from the connecting pipe, a sealing piston slidably connected to the upper end of the inside of the water storage pipe, a connecting adjustment mechanism fixedly connected to the top of the sealing piston, a sliding piston fixedly connected to the top of the connecting adjustment mechanism, a slip ring slidably connected to the outside of the sliding piston, and the slip ring fixedly connected to the inner wall of the feed pipe.

[0007] Furthermore, the connection adjustment mechanism includes a connecting rod, a sleeve, and a fixing bolt. The bottom of the connecting rod is fixedly connected to the top of the sealing piston, the top of the sleeve is fixedly connected to the bottom of the sliding piston, the sleeve is slidably connected to the feed pipe, the connecting rod is slidably connected to the sleeve, and a fixing bolt is threadedly connected to one side of the lower end of the sleeve. The end of the fixing bolt abuts against the connecting rod.

[0008] Furthermore, both ends of the connecting bend are slidably connected with threaded sleeves, and the two threaded sleeves are respectively threadedly connected to the connecting pipe and the water storage pipe.

[0009] Furthermore, the outer wall of the threaded sleeve is fixedly connected with a plurality of levers, which are evenly distributed.

[0010] Furthermore, sealing gaskets are provided at both ends of the connecting bend, and the sealing gaskets are fixedly connected to the connecting bend.

[0011] Furthermore, a set of positioning rings is fixedly connected to both the upper and lower ends of the water storage pipe, and a bracket is provided between each set of positioning rings, with the water storage pipe slidably connected to the bracket.

[0012] Furthermore, the top and bottom of the inner side of the slip ring are chamfered.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This sugar replenishment device for microbial fermentation tanks works by depleting the sugar solution inside the tank. Under atmospheric pressure, the sealing piston reaches its lowest point, and the sliding piston is positioned below the slip ring. Sugar solution is then injected into the tank body through the feed pipe. As the sugar solution level rises, the end of the elastic membrane near the tank body is also subjected to hydraulic pressure, which compresses the water inside the storage pipe, raising the water level. The sealing piston and sliding piston gradually rise until the sliding piston seals the slip ring, thus completing the sugar replenishment process. The entire process is simple and convenient, and because it utilizes atmospheric pressure and the principle of communicating vessels, it is less susceptible to interference, improving measurement accuracy.

[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] Please see Figure 1-5A sugar-supplementing device for a microbial fermentation tank includes a sugar-supplementing tank body 1. A feed pipe 2 is fixedly connected to one side of the top of the sugar-supplementing tank body 1. A connecting pipe 3 is fixedly connected to the lower end of the sugar-supplementing tank body 1 near the feed pipe 2. A connecting bend 6 is connected to the end of the connecting pipe 3 away from the sugar-supplementing tank body 1. An elastic membrane 10 is fixedly connected inside the connecting bend 6. A water storage pipe 5 is connected to the end of the connecting bend 6 away from the connecting pipe 3. A sealing piston 11 is slidably connected to the upper end inside the water storage pipe 5. A connecting adjustment mechanism is fixedly connected to the top of the sealing piston 11. A sliding piston 14 is fixedly connected to the top of the connecting adjustment mechanism. A slip ring 15 is slidably connected to the outside of the sliding piston 14. The slip ring 15 is fixedly connected to the inner wall of the feed pipe 2.

[0018] Before use, the sugar replenishing device for a microbial fermentation tank of this utility model involves connecting the water storage pipe 5, the connecting bend 6, and the connecting pipe 3 together. Then, a certain amount of clean water is injected into the water storage pipe 5. Next, the sealing piston 11 is inserted into the upper end of the water storage pipe 5. Finally, the position of the sliding piston 14 is adjusted and fixed using the connecting adjustment mechanism. The adjustment standard is that when the sugar solution inside the sugar replenishing tank body 1 reaches the required amount, the sliding piston 14 is in contact with the slip ring 15, closing the feed pipe 2. The sugar replenishing tank body 1 can then be used normally. When the sugar solution inside the sugar replenishing tank body 1 is used up, the sealing piston 11 will be pushed to its lowest position by atmospheric pressure. At this point, the sliding piston 14 is also below the slip ring 15. Then, sugar solution can be injected into the sugar replenishment tank body 1 through the feed pipe 2. As the sugar solution level in the sugar replenishment tank body 1 rises, the end of the elastic membrane 10 near the sugar replenishment tank body 1 will also be subjected to the pressure of the sugar solution, which will squeeze the water inside the water storage pipe 5, raising the liquid level inside the water storage pipe 5. The sealing piston 11 and the sliding piston 14 will also gradually rise until the sliding piston 14 seals the position of the slip ring 15. In this way, the sugar solution replenishment work can be completed. The whole process is simple and convenient. Moreover, since it uses atmospheric pressure and the principle of communicating vessels, the accuracy of measurement is not easily affected, thus improving the accuracy of measurement.

[0019] It is worth noting that a valve is installed at the end of the feed pipe 2 away from the main body of the sugar replenishment tank 1. This valve is located above the slip ring 15 and will only open after the sugar liquid in the main body of the sugar replenishment tank 1 is completely used up. At other times, it is in a closed state. Therefore, even if the sliding piston 14 and the slip ring 15 are misaligned, only the part of the sugar liquid between the valve and the slip ring 15 will enter the main body of the sugar replenishment tank 1. This part of the sugar liquid will not affect the metering accuracy.

[0020] like Figure 2 , Figure 4 and Figure 5As shown, the connecting adjustment mechanism includes a connecting rod 12, a sleeve 13, and a fixing bolt 16. The bottom of the connecting rod 12 is fixedly connected to the top of the sealing piston 11, the top of the sleeve 13 is fixedly connected to the bottom of the sliding piston 14, the sleeve 13 is slidably connected to the feed pipe 2, the connecting rod 12 is slidably connected to the sleeve 13, and a fixing bolt 16 is threadedly connected to one side of the lower end of the sleeve 13. The end of the fixing bolt 16 abuts against the connecting rod 12.

[0021] Specifically, when using it for the first time, after injecting a certain amount of sugar solution into the main body 1 of the sugar replenishment tank (this amount refers to the measurement required for subsequent processing), slide the sliding piston 14 until it just contacts the slip ring 15 and can block the feed pipe 2, and then tighten the fixing bolt 16. The adjustment process is simple, convenient and easy to operate.

[0022] like Figure 1 , Figure 3 and Figure 5 As shown, threaded sleeves 8 are slidably connected to both ends of the connecting bend 6, and the two threaded sleeves 8 are threadedly connected to the connecting pipe 3 and the water storage pipe 5 respectively.

[0023] like Figure 1 and Figure 5 As shown, multiple levers are fixedly connected to the outer wall of the threaded sleeve 8, and the levers are evenly distributed.

[0024] Specifically, the water storage pipe 5, the connecting bend 6, and the connecting pipe 3 are connected together by the threaded sleeve 8, making the installation and disassembly of the water storage pipe 5, the connecting bend 6, and the connecting pipe 3 simpler and more convenient, and also more convenient when the elastic membrane 10 fails and needs to be replaced.

[0025] like Figure 3 and Figure 5 As shown, sealing gaskets 9 are provided at both ends of the connecting bend 6, and the sealing gaskets 9 are fixedly connected to the connecting bend 6.

[0026] Specifically, the sealing gasket 9 improves the sealing between the water storage pipe 5, the connecting bend 6, and the connecting pipe 3, preventing water or sugar solution from leaking out from the connection.

[0027] like Figure 1 and Figure 5 As shown, a set of positioning rings 7 are fixedly connected to both the upper and lower ends of the water storage pipe 5, and a bracket 4 is provided between each set of positioning rings 7. The water storage pipe 5 is slidably connected to the bracket 4.

[0028] Specifically, the water storage pipe 5 is restricted by the bracket 4 to prevent it from being lost or damaged.

[0029] like Figure 4 As shown, chamfers are provided at the top and bottom of the inner side of the slip ring 15.

[0030] Specifically, the opening has a chamfer, which makes it easier for the sliding piston 14 to enter the slip ring 15.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
