Description

Technical Field

[0001] This utility model relates to the field of antibacterial agent production technology, and in particular to a bioreactor for antibacterial agent production. Background Technology

[0002] Antimicrobial agents are chemical or biological agents that can inhibit or prevent the growth and reproduction of bacteria. Their core function is not to kill microorganisms immediately, but to prevent them from multiplying by interfering with the cell structure, metabolic processes or enzyme systems of bacteria, thereby controlling the number of microorganisms at a low level.

[0003] Bioreactors for antibacterial agent production are core equipment specifically designed for the biosynthesis of antibacterial agents. Their core function is to provide a controllable reaction environment for biological systems such as microorganisms, cells, or enzymes, thereby promoting their efficient synthesis of the target antibacterial agent.

[0004] In existing bioreactors, reactants tend to adhere to or accumulate on the inner wall of the container during operation. This prevents these reactants from fully contacting the reaction system, resulting in not only a waste of raw materials but also affecting the overall adequacy of the reaction due to uneven distribution of reactants in certain areas, thereby reducing the effective processing efficiency of the reactor. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bioreactor for the production of antibacterial agents, aiming to improve the problem in the prior art where reactants easily adhere to the inner wall of the container, resulting in low reactor processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bioreactor for producing antibacterial agents, comprising a reaction vessel, a motor fixedly connected to the top of the reaction vessel, a rotating rod rotatably connected inside the reaction vessel, the top of the rotating rod fixedly connected to the output end of the motor, the bottom of the rotating rod rotatably connected to the inner bottom wall of the reaction vessel, a reciprocating threaded groove formed on the outer wall of the rotating rod, a threaded ring threadedly connected to the reciprocating threaded groove of the rotating rod, a support column fixedly connected to the side wall of the threaded ring, a scraper fixedly connected to one end of the support column, the side wall of the scraper slidably connected to the inner wall of the reaction vessel, a plurality of stirring blades fixedly connected to the side wall of the threaded ring, a feed pipe fixedly connected to the top of the reaction vessel, a discharge pipe fixedly connected to the bottom of the reaction vessel, a discharge valve fixedly provided on the outer wall of the discharge pipe, and a filter assembly installed inside the discharge pipe.

[0007] By adopting the above scheme, the rotation of the motor drives the rotation of the threaded ring, which in turn drives the rotation of the stirring blade. While the threaded ring rotates, it moves up and down on the outer wall of the rotating rod, which in turn drives the scraper to slide back and forth on the inner wall of the reaction vessel, thereby removing reactants that are attached to or accumulated on the inner wall of the reaction vessel, improving the utilization rate of reactants and increasing the rate of product formation.

[0008] Preferably, the filtration assembly includes an inlet plate and a filter plate, wherein the inlet plate has an inlet port on its side wall and the filter plate has a filter mesh on its side wall.

[0009] Preferably, the side wall of the liquid inlet plate is fixedly connected with a locking post, the side wall of the filter plate is provided with a locking groove, the locking post and the locking groove are inserted into each other, and the top of the liquid inlet plate is fixedly connected with a handle.

[0010] Preferably, a limiting post is fixedly connected to the bottom of the filter plate, a limiting groove is formed on the inner wall of the discharge pipe, the limiting post and the limiting groove are engaged, and a liquid storage tank is fixedly connected to one end of the discharge pipe.

[0011] Preferably, the side wall of the reaction vessel has multiple sets of heating chambers, and an electric heating plate is fixedly connected inside the heating chamber.

[0012] Preferably, a protective shell is fixedly connected to the outer wall of the reaction vessel, and a support frame is fixedly connected to the bottom of the protective shell.

[0013] Preferably, a drain pipe is fixedly connected to the bottom of the reaction vessel, and a drain valve is fixedly installed on the outer wall of the drain pipe.

[0014] Preferably, a temperature sensor is fixedly connected to the top of the reaction vessel, and an exhaust pipe is fixedly connected to the top of the reaction vessel.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the rotation of the motor drives the rotation of the threaded ring, which in turn drives the rotation of the stirring blade. While the threaded ring rotates, it moves up and down on the outer wall of the rotating rod, which in turn drives the scraper to slide back and forth on the inner wall of the reaction vessel, thereby removing reactants that are attached to or accumulated on the inner wall of the reaction vessel, improving the utilization rate of reactants, increasing the rate of product formation, and improving the problem in the prior art where reactants easily adhere to the inner wall of the container, resulting in low reactor processing efficiency.

[0016] 2. In this utility model, the filter plate and the liquid inlet plate are connected by the insertion of the locking post and the locking groove. The filter assembly is installed inside the discharge pipe by the locking of the limiting post and the limiting groove, so as to filter the impurities remaining in the liquid and collect the pure antibacterial agent.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figures 1-5This utility model provides an embodiment of a bioreactor for producing an antibacterial agent, comprising a reaction tank 1. A motor 2 is fixedly connected to the top of the reaction tank 1. A rotating rod 3 is rotatably connected inside the reaction tank 1. The top of the rotating rod 3 is fixedly connected to the output end of the motor 2. The bottom of the rotating rod 3 is rotatably connected to the inner bottom wall of the reaction tank 1. A reciprocating threaded groove is formed on the outer wall of the rotating rod 3. A threaded ring 4 is threadedly connected to the reciprocating threaded groove of the rotating rod 3. A support column 5 is fixedly connected to the side wall of the threaded ring 4. A scraper 6 is fixedly connected to one end of the support column 5. The side wall of the scraper 6 is slidably connected to the inner wall of the reaction tank 1. Several stirring blades 26 are fixedly connected to the side wall of the threaded ring 4. A feed pipe 7 is fixedly connected to the top of the reaction tank 1. A discharge pipe 8 is fixedly connected to the bottom of the reaction tank 1. A discharge valve 13 is fixedly installed on the outer wall of the discharge pipe 8. A filter assembly is installed inside the discharge pipe 8.

[0021] Specifically, motor 2 drives rotating rod 3 to rotate, support column 5 connects scraper 6 and threaded ring 4, feed pipe 7 is used to add reactants or other materials, discharge valve 13 controls the opening and closing of discharge pipe 8, the outer diameter of scraper 6 is the same as the inner diameter of reaction tank 1, and reciprocating thread is a continuous thread formed by alternating right-handed and left-handed helical segments. Reciprocating thread groove is the groove between two adjacent threads of reciprocating thread, such as the reciprocating screw in the prior art. It uses the periodic reversal of the thrust direction of the helical surface to realize the automatic switching of the lifting direction. When this device is needed, motor 2 is started, and the output end of motor 2 drives rotating rod 3. The rotation of the rotating rod 3 causes the threaded ring 4 to rotate, which in turn causes the stirring blade 26 to rotate. The stirring blade 26 rotates and stirs the reactants inside the reaction vessel 1, allowing the microorganisms to come into full contact with the reactants, thereby increasing the product generation rate. While rotating, the threaded ring 4 moves back and forth in the reciprocating threaded groove on the outer wall of the rotating rod 3, which in turn causes the support column 5 to rise and fall, thereby causing the scraper 6 to scrape up and down on the inner wall of the reaction vessel 1, removing the reactants that adhere to or accumulate on the side wall of the reaction vessel 1, thereby improving the utilization rate of the reactants. This improves the problem in the prior art where reactants easily adhere to the inner wall of the container, resulting in low reactor processing efficiency.

[0022] Reference Figure 3 and Figure 4 The filtration assembly includes an inlet plate 9 and a filter plate 10. The inlet plate 9 has an inlet port on its side wall, and the filter plate 10 has filter mesh holes on its side wall. A locking post 11 is fixedly connected to the side wall of the inlet plate 9, and a locking groove 12 is opened on the side wall of the filter plate 10. The locking post 11 and the locking groove 12 are inserted into each other. A handle 14 is fixedly connected to the top of the inlet plate 9, and a limiting post 15 is fixedly connected to the bottom of the filter plate 10. A limiting groove 16 is opened on the inner wall of the discharge pipe 8, and the limiting post 15 and the limiting groove 16 are engaged. A liquid storage tank 17 is fixedly connected to one end of the discharge pipe 8.

[0023] Specifically, the storage tank 17 is used to collect the antibacterial agent after the reaction is complete. The inlet plate 9 and the filter plate 10 are connected by the slot 12 and the post 11, which can achieve the effect of quick installation and disassembly. The inlet plate 9 and the filter plate 10 can also be connected to the limiting groove 16 on the inner wall of the discharge pipe 8 by the limiting post 15, so as to realize the quick splicing and disassembly of the filter assembly and the discharge pipe 8. When the discharge valve 13 is opened, the antibacterial agent after the reaction is complete enters from the inlet plate 9. The filter plate 10 filters the impurities entrained in the liquid. The impurities fall into the groove formed inside the inlet plate 9 and the filter plate 10. After collection is completed, the filter assembly can be taken out from the discharge pipe 8 by the handle 14. Opening the inlet plate 9 and the filter plate 10 can also achieve the effect of cleaning the filter assembly.

[0024] Reference Figure 2 and Figure 5 The side wall of the reaction vessel 1 has multiple heating chambers 18. An electric heating plate 19 is fixedly connected inside the heating chamber 18. A protective shell 20 is fixedly connected to the outer wall of the reaction vessel 1. A support frame 25 is fixedly connected to the bottom of the protective shell 20. A drain pipe 21 is fixedly connected to the bottom of the reaction vessel 1. A drain valve 22 is fixedly installed on the outer wall of the drain pipe 21. A temperature sensor 23 is fixedly connected to the top of the reaction vessel 1. An exhaust pipe 24 is fixedly connected to the top of the reaction vessel 1.

[0025] Specifically, the heating chamber 18 is used to place the electric heating plate 19, which is used to heat the reaction vessel 1 and accelerate the reaction rate between microorganisms and reactants. The protective shell 20 is used to prevent the reaction vessel 1 from being damaged by external impact and to install the support frame 25 to support the reaction vessel 1. The drain valve 22 is used to control the opening and closing of the drain pipe 21, which is used to clean the reaction vessel 1 after use. The temperature sensor 23 is used to monitor the temperature inside the reaction vessel 1 in real time. The exhaust pipe 24 is used to discharge the waste gas inside the reaction vessel 1. When this device is needed, the electric heating plate 19 is turned on and the drain valve 22 is closed. The temperature inside the reaction vessel 1 is adjusted to the most suitable temperature by the electric heating plate 19, so that the microorganisms and reactants are in the most active reaction state. After the reaction is completed, the cleaning liquid is added into the reaction vessel 1 through the feed pipe 7. The rotation of the threaded ring 4 drives the scraper 6 to clean the inner wall of the reactants. The drain valve 22 is opened and the cleaning liquid is discharged from the reaction vessel 1 through the drain pipe 21, thereby completing the cleaning effect of the reaction vessel 1.

[0026] Working principle: When the device is needed, start motor 2. Motor 2 drives the rotating rod 3 to rotate, which in turn drives the stirring blade 26 to rotate, so that the microorganisms and reactants can come into full contact. At the same time, the scraper 6 drives the scraper 6 to scrape up and down on the inner wall of the reaction tank 1, thereby removing the reactants that are attached to or accumulated on the side wall of the reaction tank 1, thus improving the utilization rate of the reactants. When the reaction is completed, open the discharge valve 13, and filter the impurities in the reaction liquid through the inlet plate 9 and the filter plate 10, thereby collecting the pure antibacterial agent into the storage tank 17.

[0027] When the device is finished, close the discharge valve 13, remove the filter assembly through the handle 14, open the inlet plate 9 and the filter plate 10 to clean the impurities stored in the grooves formed inside the inlet plate 9 and the filter plate 10, add cleaning liquid into the reaction tank 1 through the feed pipe 7, and clean the inner wall of the reactants by rotating the threaded ring 4 and driving the scraper 6. Open the drain valve 22 and discharge the cleaning liquid from the reaction tank 1 through the drain pipe 21, thereby completing the cleaning effect of the reaction tank 1.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
