Description

Technical Field

[0001] This utility model relates to the field of microbial production technology, and in particular to a feeding device for Bacillus licheniformis engineering. Background Technology

[0002] Bacillus licheniformis is a Gram-positive, aerobic or facultative anaerobic rod-shaped bacterium belonging to the genus Bacillus. It can form endospores and has strong resistance to high temperature, dryness and chemical disinfectants. It is widely found in soil, plant surface and water. As an important industrial strain, Bacillus licheniformis is widely used in enzyme preparation production, biopharmaceuticals and environmental remediation.

[0003] In its industrial production, the performance of the feeding system directly affects cell concentration, product yield, and production cost. Traditional feeding devices have the following technical bottlenecks:

[0004] 1. Material clumping and poor flowability:

[0005] Common carbon sources (such as starch and glucose) and organic nitrogen sources (such as soybean meal) are prone to absorbing moisture and clumping, leading to pipe blockage. Traditional mixing devices (such as anchor or paddle mixers) can only provide a single rotational shear force, which has limited effect on crushing high-viscosity materials, resulting in a high clumping rate and requiring frequent shutdowns for cleaning, affecting production continuity.

[0006] 2. Insufficient mixing uniformity:

[0007] Existing feeding systems mostly use static mixing or simple stirring, which makes it difficult to achieve uniform mixing of multi-component materials (such as carbon sources, nitrogen sources, and trace elements). Under traditional mixing methods, the concentration of nutrients deviates significantly, leading to imbalance in cell metabolism and reduced product synthesis efficiency.

[0008] Therefore, it is necessary to provide a new feeding device for Bacillus licheniformis engineering to solve the above-mentioned technical problems. Utility Model Content

[0009] To solve the above-mentioned technical problems, this utility model provides a feeding device for Bacillus licheniformis engineering.

[0010] The feeding device for Bacillus licheniformis engineering provided by this utility model includes: a fermenter, a power box, a crushing component, and a drive component. A metering pump is provided on one side of the fermenter, and a batching tank is provided on the other side of the metering pump. The input end of the metering pump is connected to the bottom of the batching tank through a pipe, and the output end of the metering pump is connected to the top of the fermenter through a pipe. The power box is fixedly connected to the top of the fermenter, and a waste discharge pipe is fixedly connected to the bottom of the fermenter. A waste discharge valve is fixedly connected to the middle of the waste discharge pipe. A crushing component for crushing agglomerated batching materials is installed inside the batching tank. The crushing component includes: a rotating shaft, which is rotatably connected to the axis of the batching tank. A drive component for driving the rotating shaft to rotate is installed inside the power box.

[0011] Preferably, the crushing component includes: blades, mixing rods, and scrapers. Multiple sets of blades for cutting agglomerated ingredients are symmetrically fixedly connected to the bottom of the rotating shaft. Multiple sets of mixing rods are equidistantly fixedly connected to the middle of the rotating shaft. Each set of mixing rods has a scraper fixedly connected to its end away from the rotating shaft for scraping off ingredients from the inner wall of the mixing tank.

[0012] Preferably, the drive assembly includes: a drive motor, a worm gear, a worm wheel, an eccentric wheel, a collar, a transmission rod, a U-shaped connecting rod, and a rotating ring. The top of the power box is fixedly connected to the drive motor, the output end of the drive motor is fixedly connected to the worm gear, the bottom of the worm gear is slidably connected to the rotating shaft, the inside of the power box is rotatably connected to the worm wheel, the worm wheel is meshed with the worm gear, both sides of the worm wheel are fixedly connected to the eccentric wheel, the outer wall of the eccentric wheel is rotatably connected to the collar, the bottom of the collar is fixedly connected to the transmission rod, the bottom of the power box is slidably connected to the U-shaped connecting rod, the middle part of the U-shaped connecting rod is slidably connected to the bottom of the transmission rod, the top of the rotating shaft is rotatably connected to the rotating ring, and the outer wall of the rotating ring is fixedly connected to one end of the U-shaped connecting rod.

[0013] Preferably, the bottom of the worm gear is hollow and has an external spline, and the top of the shaft has an internal spline, with the external spline and the internal spline being slidably connected.

[0014] Preferably, the rotatable connection between the ring and the shaft is located below the internal spline at the top of the shaft.

[0015] Preferably, the power box has a groove inside, and the U-shaped connecting rod slides in the groove.

[0016] Preferably, a feed pipe is fixedly connected to the top of the mixing barrel, and an annular heater is fixedly connected to the outer wall of the mixing barrel.

[0017] Preferably, a discharge valve is fixedly connected to the pipeline between the batching tank and the metering pump, and valve motors for controlling the opening and closing of the discharge valve and the waste discharge valve are symmetrically fixedly connected to the bottom of the batching tank.

[0018] Compared with related technologies, the feeding device for Bacillus licheniformis engineering provided by this utility model has the following beneficial effects:

[0019] Highly efficient at breaking up clumps:

[0020] The device has a crushing component installed inside the mixing tank. Multiple sets of blades are symmetrically fixed to the bottom of the rotating shaft. When the drive component drives the rotating shaft to rotate, the blades will rotate at high speed, which can quickly cut the lumps in the ingredients. For some materials that are prone to lumping, such as starch and soybean meal, these blades can quickly crush larger lumps into smaller particles. The symmetrical distribution design of the blades allows them to cover all areas at the bottom of the mixing tank during the rotation of the rotating shaft, ensuring that all lumps can be effectively cut, avoiding crushing dead corners, and ensuring the overall quality of the ingredients.

[0021] To prevent the clumps from reforming:

[0022] The mixing rod and scraper in the middle of the rotating shaft also play an important role in the process of breaking up agglomerates. The mixing rod stirs the ingredients so that the crushed material particles can be dispersed in time to avoid re-agglomeration and agglomeration. The scraper can scrape off the ingredients attached to the inner wall of the mixing tank to prevent these ingredients from accumulating and agglomerating on the tank wall, further ensuring the fluidity and uniformity of the ingredients.

[0023] The unique drive mechanism enhances the crushing and mixing effects:

[0024] The drive components inside the power box employ a complex and ingenious design. The drive motor drives the worm to rotate, and the worm meshes with the worm wheel. The eccentric wheels on both sides of the worm wheel then perform circular motion. Through the transmission of the collar, transmission rod, U-shaped connecting rod, and rotating ring, the rotating shaft can also perform a certain range of reciprocating lifting and lowering while rotating. This lifting and lowering increases the range of motion trajectory of the blades, enabling more comprehensive contact and crushing of clumps compared to the traditional single rotation method.

It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 4 A feeding device for Bacillus licheniformis engineering is disclosed. The feeding device includes: a fermenter 1, a power unit 4, a crushing component, and a drive component. A metering pump 2 is installed on one side of the fermenter 1, and a batching tank 3 is installed on the other side of the metering pump 2. The input end of the metering pump 2 is connected to the bottom of the batching tank 3 via a pipe, and the output end of the metering pump 2 is connected to the top of the fermenter 1 via a pipe. The power unit 4 is fixedly connected to the top of the fermenter 1, and a waste discharge pipe 5 is fixedly connected to the bottom of the fermenter 1. A waste discharge valve 6 is fixedly connected to the middle of the waste discharge pipe 5. A crushing component for crushing agglomerated batching materials is installed inside the batching tank 3. The crushing component includes: a rotating shaft 7, which is rotatably connected to the axis of the batching tank 3. The internal drive assembly for driving the rotating shaft 7 is installed in the force box 4. The crushing assembly includes: blades 8, mixing rods 9 and scrapers 10. Multiple sets of blades 8 for cutting material agglomerates are symmetrically fixedly connected to the bottom of the rotating shaft 7. Multiple sets of mixing rods 9 are equidistantly fixedly connected to the middle of the rotating shaft 7. Each set of mixing rods 9 is fixedly connected to a scraper 10 for scraping off the material from the inner wall of the batching barrel 3 at the end away from the rotating shaft 7. A feed pipe 19 is fixedly connected to the top of the batching barrel 3. An annular heater 20 is fixedly connected to the outer wall of the batching barrel 3. A discharge valve 23 is fixedly connected to the pipeline between the batching barrel 3 and the metering pump 2. A valve motor 21 for controlling the opening and closing of the discharge valve 23 and the waste discharge valve 6 is symmetrically fixedly connected to the bottom of the batching barrel 3.

[0033] It should be noted that the annular heater 20 can heat the ingredients in the mixing tank 3, which can keep the ingredients at a suitable temperature, help improve the fluidity and activity of the ingredients, and also prevent some easily crystallizing ingredients from clumping due to excessively low temperature.

[0034] Please see Figure 3and Figure 4 The drive assembly includes: a drive motor 11, a worm gear 12, a worm wheel 13, an eccentric wheel 14, a collar 15, a transmission rod 16, a U-shaped connecting rod 17, and a rotating ring 18. The drive motor 11 is fixedly connected to the top of the power box 4. The output end of the drive motor 11 is fixedly connected to the worm gear 12. The bottom of the worm gear 12 is slidably connected to the rotating shaft 7. The worm wheel 13 is rotatably connected inside the power box 4, meshing with the worm gear 12. Eccentric wheels 14 are fixedly connected to both sides of the worm wheel 13. A collar 15 is rotatably connected to the outer wall of each eccentric wheel 14. A transmission rod 16 is fixedly connected to the bottom of each collar 15. A U-shaped connecting rod 17 is slidably connected to the bottom of the transmission rod 16 and the power box 4. The middle part of the U-shaped connecting rod 17 is slidably connected to the bottom of the transmission rod 16. A rotating ring 18 is rotatably connected to the top of the rotating shaft 7. The outer wall of the rotating ring 18 is fixedly connected to one end of the U-shaped connecting rod 17. The bottom of the worm gear 12 is hollow and has an external spline. The top of the rotating shaft 7 has an internal spline. The external spline and the internal spline are slidably connected. The rotatable connection between the rotating ring 18 and the rotating shaft 7 is located below the internal spline on the top of the rotating shaft 7. A sliding groove 22 is provided inside the power box 4. The U-shaped connecting rod 17 slides in the sliding groove 22.

[0035] It should be noted that the slide groove 22 can restrict the displacement of the U-shaped connecting rod 17, so that the U-shaped connecting rod 17 can only move up and down along the direction of the slide groove 22. The design of the internal spline and the external spline makes the rotating shaft 7 rotate with the worm gear 12. At the same time, the rotating shaft 7 can also move up and down with the U-shaped connecting rod 17.

[0036] The working principle of the feeding device for Bacillus licheniformis engineering provided by this utility model is as follows:

[0037] Ingredient preparation and feeding:

[0038] The operator adds various ingredients required for the production of Bacillus licheniformis into the mixing tank 3 through the feed pipe 19 fixedly connected to the top of the mixing tank 3. The ingredients may include nutrients such as carbon source, nitrogen source, and inorganic salt. The annular heater 20 fixedly connected to the outer wall of the mixing tank 3 starts to work and heats the ingredients in the mixing tank 3. This keeps the ingredients at a suitable temperature, which helps to improve the fluidity and activity of the ingredients. It also prevents some easily crystallized ingredients from clumping due to low temperature. At the same time, it can also create certain temperature conditions for the subsequent fermentation process.

[0039] Crushing components break up agglomerates:

[0040] The drive assembly inside the power box 4 starts operating, the drive motor 11 starts, and the worm gear 12 fixedly connected to its output end rotates accordingly. Since the bottom of the worm gear 12 is hollow and has an external spline, the worm gear 12 is slidably connected to the internal spline on the top of the rotating shaft 7. Therefore, when the worm gear 12 rotates, it will drive the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, the multiple sets of blades 8 symmetrically fixedly connected to its bottom will rotate accordingly. These blades 8 are used to cut the lumps in the ingredients, breaking the larger lumps into smaller particles, so as to facilitate the absorption of nutrients by Bacillus licheniformis during subsequent transportation and fermentation. The multiple sets of mixing rods 9 fixedly connected at equal intervals in the middle of the rotating shaft 7 will also rotate with the rotating shaft 7 to stir and mix the ingredients, so that the various ingredients are fully and evenly mixed, ensuring that Bacillus licheniformis in the fermentation tank 1 can obtain a balanced supply of nutrients. The scraper 10 fixedly connected to the end of the mixing rod 9 away from the rotating shaft 7 will scrape off the ingredients attached to the inner wall of the ingredient tank 3 as the mixing rod 9 rotates, preventing the ingredients from accumulating and clumping on the tank wall, and ensuring the full utilization of the ingredients.

[0041] The rotating shaft 7 performs a reciprocating lifting motion during rotation:

[0042] When the worm gear 12 rotates, the worm wheel 13 meshing with it will also rotate. The eccentric wheels 14 fixedly connected to both sides of the worm wheel 13 will move in a circular motion together with the worm wheel 13. The collar 15 rotatably connected to the outer wall of the eccentric wheel 14 will move with the circular motion of the eccentric wheel 14. The transmission rod 16 fixedly connected to the bottom of the collar 15 will also move. The U-shaped connecting rod 17 slidably connected to the bottom of the power box 4 will slide back and forth in the sliding groove 22 opened inside the power box 4 under the action of the transmission rod 16. Since the outer wall of the rotating ring 18 is fixedly connected to one end of the U-shaped connecting rod 17, and the rotating ring 18 is rotatably connected to the top of the rotating shaft 7, the back and forth movement of the U-shaped connecting rod 17 will cause the rotating ring 18 to drive the rotating shaft 7 to move back and forth within a certain range, thereby enhancing the working effect of the blade 8, mixing rod 9 and scraper 10 on the rotating shaft 7, and making the agglomeration crushing and batching mixing more thorough.

[0043] Material replenishment and conveying:

[0044] After the ingredients are crushed and mixed in the ingredient tank 3, the discharge valve 23, which is fixedly connected to the pipeline between the ingredient tank 3 and the metering pump 2, is opened under the control of the valve motor 21 connected to it. The metering pump 2 starts to work. The input end of the metering pump 2 is connected to the bottom of the ingredient tank 3 through a pipeline. It will deliver the ingredients in the ingredient tank 3 at a precise flow rate. The output end of the metering pump 2 is connected to the top of the fermentation tank 1 through a pipeline. After passing through the metering pump 2, the ingredients are delivered to the fermentation tank 1 to provide the necessary nutrients for the growth of Bacillus licheniformis.

[0045] Cleaning ingredient container 3:

[0046] After the ingredients are conveyed, cleaning liquid can be introduced through the feed inlet at the top of the ingredient tank 3. Then, the drive motor 11 is started. The drive motor 11 drives the rotating rod to rotate and reciprocate. The rotating rod drives the mixing rod 9, which is fixedly connected to it, to move synchronously. The mixing rod 9 drives the scraper 10 to move synchronously, thereby cleaning the ingredient tank 3. After cleaning, the waste discharge valve 6 at the bottom of the ingredient tank 3 is opened under the drive of the valve motor 21 connected to it, and the waste liquid flows out from the waste discharge pipe 5.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
