Description

Technical Field

[0001] This utility model belongs to the field of culture vessel technology, specifically relating to a multi-stage culture vessel for alkaline protease. Background Technology

[0002] Alkaline protease multistage culture tanks are commonly used in industrial fermentation processes, especially when large-scale production of alkaline protease is required. Alkaline protease has wide applications in cleaning agents, food processing, leather, and textile industries.

[0003] Chinese patent CN220597438U discloses a multi-stage alkaline protease culture vessel. The vessel includes a culture rack composed of connecting rods, baffles, and shelves, forming multiple layers of storage space for culturing alkaline protease. A rotating shaft is connected to the bottom of the connecting rods, allowing for easy placement, removal, and observation of the protease through manual rotation of the culture rack at the vessel door. A hot and cold air generator is located at the bottom of the vessel, producing and outputting hot and cold air. This air passes through an air chamber and several vents at the top of the air chamber, providing a uniform supply of hot and cold air to the vessel, creating a favorable environment for alkaline protease culture, reducing the difficulty of cultivation, and improving its efficiency. An exhaust pipe at the top of the vessel ensures air circulation within the vessel, maintaining a suitable culture environment for the alkaline protease and guaranteeing its cultivation effect.

[0004] However, the current culture tanks have the following problems: the above-mentioned application uses a culture rack with connecting rods, baffles and shelf assemblies, which cannot continuously add appropriate amounts of nutrients to the cultured protease. Therefore, we propose an alkaline protease multi-stage culture tank. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage alkaline protease culture vessel that can solve the problem in related technologies where it is impossible to continuously add appropriate amounts of nutrients to the cultured protease.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A multi-stage alkaline protease culture tank includes a placement plate, a culture tank fixedly connected to the top of the placement plate, a feed inlet on the top of the culture tank, and a feeding device on the top of the culture tank.

[0008] The feeding device includes a feeding box, the side of which is fixedly connected to the inner wall of the culture tank. A motor is fixedly connected to the top of the feeding box, and a rotating shaft is fixedly connected to the output shaft of the motor. The circumferential surface of the rotating shaft rotates through the inner wall of the feeding box. A discharge port is provided at the bottom of the feeding box. A half gear is fixedly connected to the circumferential surface of the rotating shaft. A rack is slidably connected to the bottom of the feeding box. A connecting strip is fixedly connected to the back side of the rack, and a baffle is fixedly connected to the side of the connecting strip.

[0009] A fixing plate is fixedly connected to the circumference of the rotating shaft, and a force-bearing plate is fixedly connected to the front and side of the feeding box. The function of the fixing plate is to disperse the falling nutrients and make them more evenly distributed.

[0010] A tension spring is fixedly connected to the back side of the force plate. The end of the tension spring away from the force plate is fixedly connected to the front side of the rack. The function of the tension spring is to allow the rack to reset when the half gear rotates to the toothless side and no longer pushes the rack to move.

[0011] The number of discharge ports and baffles is set to two, and they are symmetrical to each other along the vertical central axis of the feeding box. The circumferential surface of the half gear is symmetrical to the side surface of the rack. The purpose of the symmetry between the circumferential surface of the half gear and the side surface of the rack is to push the rack to move when the half gear rotates.

[0012] The culture tank is equipped with an exhaust device on its circumferential surface. The exhaust device includes a bevel gear, the top of which is fixedly connected to the bottom of a rotating shaft. An exhaust port is provided on the circumferential surface of the culture tank. A filter cylinder is fixedly connected to the circumferential surface of the culture tank. An activated carbon plate is fixedly connected to the inner wall of the filter cylinder. A rotating rod is rotatably connected to the side of the activated carbon plate. A bevel gear is fixedly connected to the side of the rotating rod. A rotor blade is fixedly connected to the circumferential surface of the rotating rod. The bevel gear is used to drive the rotating rod to rotate, and the rotor blade is used to exhaust the gas inside the culture tank.

[0013] The inner wall of the filter cylinder is fixedly connected to an activated carbon plate and a carbon molecular sieve plate. The function of the activated carbon plate and the carbon molecular sieve plate is to filter and absorb the discharged gas.

[0014] The circumferential surface of the first bevel gear meshes with the circumferential surface of the second bevel gear. The side of the rotor blade is located to the left of the activated carbon plate. The purpose of meshing the circumferential surface of the first bevel gear with the circumferential surface of the second bevel gear is to drive the second bevel gear to rotate when the first bevel gear rotates.

[0015] The technical effects achieved by this utility model are as follows:

[0016] 1. This utility model, through the setting of the feeding device, causes the half gear to rotate, which in turn drives the rack to move. When the rack moves, it drives the baffle to move through the connecting strip, opening the discharge port of the feeding box. Nutrients in the feeding box then enter the culture tank through the discharge port. When the rotating shaft rotates, it also drives the fixing plate to rotate. When the fixing plate rotates, it disperses the nutrients falling from the discharge port, allowing them to be more evenly distributed onto the protease. When the half gear rotates to the toothless side, the rack, no longer pushed by the half gear, uses the tension spring to drive the baffle to reset and block the discharge port through the connecting strip. When the half gear rotates to the toothed side again, the above principle is repeated, thus allowing for the continuous addition of appropriate amounts of nutrients.

[0017] 2. This utility model, through the setting of the exhaust device, causes the rotating rod to rotate on the activated carbon plate when the bevel gear two rotates. Thus, when the rotating rod rotates, it can drive the rotor blades to rotate. The suction force generated by the rotation of the rotor blades can draw the gas in the culture tank out of the gas outlet. The drawn-out gas passes through the activated carbon plate one, activated carbon plate two, and carbon molecular sieve plate in sequence for filtration and absorption. Finally, the remaining filtered gas is discharged through the filter cartridge, thus ensuring that the emitted gas can be effectively discharged into the atmosphere without affecting the gas concentration in the working environment.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-5 As shown, an alkaline protease multi-stage culture tank includes a placement plate 1, a culture tank 2 fixedly connected to the top of the placement plate 1, a feed inlet 3 opened on the top of the culture tank 2, and a feeding device 4 provided on the top of the culture tank 2.

[0027] The feeding device 4 includes a feeding box 41, the side of which is fixedly connected to the inner wall of the culture tank 2. A motor 42 is fixedly connected to the top of the feeding box 41. A rotating shaft 43 is fixedly connected to the output shaft of the motor 42. The circumferential surface of the rotating shaft 43 rotates through the inner wall of the feeding box 41. A discharge port 44 is opened at the bottom of the feeding box 41. A half gear 45 is fixedly connected to the circumferential surface of the rotating shaft 43. A rack 46 is slidably connected to the bottom of the feeding box 41. A connecting strip 47 is fixedly connected to the back side of the rack 46. A baffle 48 is fixedly connected to the side of the connecting strip 47.

[0028] A fixing plate 49 is fixedly connected to the circumferential surface of the rotating shaft 43, and a force-bearing plate 410 is fixedly connected to the front and side surfaces of the feeding box 41. The function of the fixing plate 49 is to disperse the falling nutrients so that they are distributed more evenly.

[0029] A tension spring 411 is fixedly connected to the back side of the force plate 410. The end of the tension spring 411 away from the force plate 410 is fixedly connected to the front side of the rack 46. The function of the tension spring 411 is to allow the rack 46 to reset when the half gear 45 rotates to the toothless side and no longer pushes the rack 46 to move.

[0030] The number of discharge ports 44 and baffles 48 are set to two, and they are symmetrical to each other along the vertical central axis of the feed box 41. The circumferential surface of the half gear 45 is symmetrical to the side surface of the rack 46. The purpose of the symmetry between the circumferential surface of the half gear 45 and the side surface of the rack 46 is to push the rack 46 to move when the half gear 45 rotates.

[0031] Based on the above structure, firstly, when the culture tank 2 needs to culture alkaline protease, nutrients can be added to the protease using the feeding device 4. The protease to be cultured can be placed into the culture tank 2 through the feed inlet 3. Then, by starting the motor 42, when the output shaft of the motor 42 rotates, it drives the rotating shaft 43 to rotate. When the rotating shaft 43 rotates, it drives the half gear 45 to rotate. When the half gear 45 rotates, it pushes the rack 46 to move. Thus, when the rack 46 moves, it can drive the baffle 48 to move through the connecting strip 47, so that when the baffle 48 moves, it can open the discharge port 44 of the feeding box 41. The nutrients in the feeding box 41 will then enter the culture tank 2 through the discharge port 44. When the rotating shaft 43 rotates, it will also drive the fixing plate 49 to rotate. When the fixing plate 49 rotates, it can disperse the nutrients falling from the discharge port 44, so that they can be more evenly distributed on the protease. When the half gear 45 rotates to the toothless side, the rack 46 will be unable to receive the thrust of the half gear 45. The tension spring 411 will drive the baffle 48 to reset through the connecting strip 47 to block the discharge port 44. When the half gear 45 rotates to the toothed side again, the above principle will be repeated, so that an appropriate amount of nutrients can be continuously added.

[0032] like Figure 1-5 As shown, an exhaust device 5 is provided on the circumferential surface of the culture tank 2. The exhaust device 5 includes a bevel gear 51, the top of which is fixedly connected to the bottom of the rotating shaft 43. An air outlet 52 is provided on the circumferential surface of the culture tank 2. A filter cylinder 53 is fixedly connected to the circumferential surface of the culture tank 2. An activated carbon plate 54 is fixedly connected to the inner wall of the filter cylinder 53. A rotating rod 55 is rotatably connected to the side of the activated carbon plate 54. A bevel gear 56 is fixedly connected to the side of the rotating rod 55. A rotor blade 57 is fixedly connected to the circumferential surface of the rotating rod 55. The function of the bevel gear 56 is to drive the rotating rod 55 to rotate. The function of the rotor blade 57 is to exhaust the gas inside the culture tank 2.

[0033] The inner wall of the filter cylinder 53 is fixedly connected to an activated carbon plate 58 and a carbon molecular sieve plate 59. The function of the activated carbon plate 58 and the carbon molecular sieve plate 59 is to filter and absorb the discharged gas.

[0034] The circumferential surface of bevel gear 1 51 meshes with the circumferential surface of bevel gear 2 56. The side of the rotor blade 57 is located to the left of activated carbon plate 1 54. The purpose of meshing the circumferential surface of bevel gear 1 51 with the circumferential surface of bevel gear 2 56 is to drive bevel gear 2 56 to rotate when bevel gear 1 51 rotates.

[0035] According to the above structure, the rotation of the shaft 43 can drive the exhaust device 5. When the shaft 43 rotates, it will drive the first bevel gear 51 to rotate. When the first bevel gear 51 rotates, it will drive the second bevel gear 56 to rotate. When the second bevel gear 56 rotates, it will drive the rotating rod 55 to rotate on the first activated carbon plate 54. Thus, when the rotating rod 55 rotates, it can drive the rotor blade 57 to rotate. The suction force generated by the rotation of the rotor blade 57 can draw the gas in the culture tank 2 out from the gas outlet 52. The drawn gas is filtered and absorbed in sequence through the first activated carbon plate 54, the second activated carbon plate 58 and the carbon molecular sieve plate 59. Finally, the remaining filtered gas will be discharged through the filter cartridge 53, thus ensuring that the discharged gas can be effectively discharged into the atmosphere without affecting the gas concentration in the working environment.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
