Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, specifically a fermentation tank with a detachable stirring device. Background Technology

[0002] A fermenter is a specialized piece of equipment used for the culture of microorganisms or cells to complete the fermentation process. It is mainly used to produce biological products, such as antibiotics, alcoholic beverages, yogurt, and industrial enzymes. The equipment is usually equipped with a tank, a stirring device, a temperature control system, and a ventilation device. By precisely controlling parameters such as temperature, pH value, and oxygen content, it provides a suitable environment for the growth and metabolism of microorganisms. It is currently widely used in biopharmaceutical, food processing, chemical and other fields.

[0003] The stirring components in existing fermenters are usually fixed in the fermenter by threaded locking clips. Although the threaded connection structure can ensure the stability of the stirring components during operation, after repeated disassembly and assembly, fermentation material residue may accumulate in the thread gaps, which is difficult to completely remove during cleaning. If the residue breeds bacteria, it may affect the purity of subsequent batches of fermentation. In view of this, we provide a fermenter with a detachable stirring device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fermenter with a detachable stirring device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fermentation tank with a detachable stirring device, including a constant temperature tank. A cover plate is installed on the top of the constant temperature tank, and a bracket is fixedly connected to the outer wall of the bottom of the constant temperature tank. A drive motor is fixedly connected to the center of the bottom surface of the constant temperature tank, and a drive shaft is fixedly connected to the center of the top surface of the drive motor. A movable rod is provided in the center of the inner cavity of the drive shaft, and a strong spring is provided in the inner cavity of the drive shaft. A straight fastener is provided on the outer wall of the top of the movable rod, and a handle is fixedly connected to the top surface of the straight fastener. Multiple sealing rings are fixedly connected to the top of the inner wall of the drive shaft. An abutting collar is fixedly connected to the center of the outer wall of the drive shaft, and a cross stirring assembly is abutted on the top surface of the abutting collar. A straight perforation is provided on the top surface of the cross stirring assembly, and a straight groove is provided on both sides of the top surface of the cross stirring assembly.

[0006] As described above, the top of the outer wall of the drive shaft is rotatably connected to the bottom of the inner wall of the constant temperature tank via a rotating shaft, and an air hole is provided at the bottom of the inner wall of the drive shaft, which is connected to the outside of the constant temperature tank.

[0007] As described above, the outer ring of the sealing ring is fixedly connected to the top of the inner wall of the drive shaft, and the inner ring of the sealing ring abuts against and is tightly fitted to the outer wall of the movable rod. The top of the outer wall of the movable rod is connected through to the center of the drive shaft, and the outer wall of the movable rod is tightly fitted to and slidably connected to the inner wall of the drive shaft.

[0008] As described above, the outer wall of the top end of the strong spring abuts against the top end of the inner wall of the drive shaft, and the outer wall of the bottom end of the strong spring abuts against the outer wall of the bottom of the movable rod.

[0009] As described above, multiple limiting components are fixedly connected to the top edge of the drive shaft, and the multiple limiting components are respectively located on both sides of the outer wall of the straight fastener. One side of the outer wall of the straight fastener is tightly fitted with the outer wall of the limiting component, and the straight fastener is located at the center of the top surface of the drive shaft.

[0010] As described above, the top surface of the contact collar abuts against and is tightly fitted to the center of the bottom surface of the cross-shaped stirring assembly.

[0011] As mentioned above, the projected patterns of the cross-shaped stirring assembly, the straight perforation, and the straight groove are consistent, and the bottom surface of the cross-shaped stirring assembly is engaged and connected to the inner wall of the straight groove.

[0012] Compared with existing technologies, this fermenter with a detachable stirring device has the following advantages:

[0013] I. This utility model, by fixing the sealing ring to the inner wall of the drive shaft and tightly clamping it between the outer wall of the drive shaft and the inner wall of the movable rod, forms an effective sealing effect, preventing fermentation materials from seeping into the connection gap between the drive shaft and the movable rod, thus reducing the possibility of residual accumulation of fermentation materials from the source. At the same time, the air hole at the bottom of the drive shaft is connected to the external air source, which can balance the air pressure inside and outside the drive shaft. If the temperature change inside the tank causes air pressure fluctuations, the air hole can also be quickly adjusted, further reducing the risk of material seepage. Even if the cross-shaped stirring assembly is disassembled and reassembled multiple times, the gap at the connection point is still not easy to retain fermentation materials. During cleaning, only a simple rinse is needed to completely remove them, greatly reducing the possibility of the growth of miscellaneous bacteria, thereby ensuring the fermentation purity of subsequent batches.

[0014] II. This utility model only requires pulling the handle upwards, compressing the powerful spring on the movable rod, causing the slotted fastener to disengage from the inner wall of the slot, rotating the cross-shaped stirring assembly 90° to align the slotted fastener with the slotted through hole, and then removing the cross-shaped stirring assembly upwards along the outer wall of the drive shaft. Installation is also simple: align the slotted through hole of the cross-shaped stirring assembly with the slotted fastener at the top of the drive shaft, press down until it abuts the top surface of the collar, and then pull the handle again and rotate 90° to align the slotted fastener with the slotted hole. After releasing the handle, the powerful spring rebounds, causing the movable rod to sink, and the slotted fastener snaps into the slot for fixation. This allows for quick disassembly and installation of the cross-shaped stirring assembly, significantly reducing equipment downtime, eliminating the risk of material residue in the threaded gaps, and making cleaning and maintenance more efficient.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-7As shown, this utility model provides a technical solution: a fermentation tank with a detachable stirring device, including a constant temperature tank 1, a cover plate 101 installed on the top of the constant temperature tank 1, and a foot bracket 102 fixedly connected to the outer wall of the bottom end of the constant temperature tank 1, a drive motor 2 fixedly connected to the center of the bottom surface of the constant temperature tank 1, and a drive shaft 201 fixedly connected to the center of the top surface of the drive motor 2, a movable rod 202 provided in the center of the inner cavity of the drive shaft 201, and a strong spring 203 provided in the inner cavity of the drive shaft 201, a straight fastener 204 on the outer wall of the top of the movable rod 202, and a handle 205 fixedly connected to the top surface of the straight fastener 204, a plurality of sealing rings 206 fixedly connected to the top of the inner wall of the drive shaft 201, an abutting collar 3 fixedly connected to the center of the outer wall of the drive shaft 201, and a cross stirring assembly 301 abutting the top surface of the abutting collar 3, a straight through hole 302 opened on the top surface of the cross stirring assembly 301, and a straight groove 303 opened on both sides of the top surface of the cross stirring assembly 301.

[0026] By fixing the sealing ring 206 to the inner wall of the drive shaft 201 and tightly clamping it between the outer wall of the drive shaft 201 and the inner wall of the movable rod 202, an effective sealing effect is formed, preventing fermentation materials from seeping into the connection gap between the drive shaft 201 and the movable rod 202, thus reducing the possibility of residual accumulation of fermentation materials from the source. At the same time, the air hole 207 at the bottom of the drive shaft 201 is connected to the external air source, which can balance the air pressure inside and outside the drive shaft 201. If the temperature change inside the tank causes air pressure fluctuations, the air hole 207 can also be quickly adjusted, further reducing the risk of material seepage.

[0027] like Figure 1 As shown, the top of the outer wall of the drive shaft 201 is rotatably connected to the bottom of the inner wall of the constant temperature tank 1 via a rotating shaft. The bottom of the inner wall of the drive shaft 201 is provided with an air hole 207, and the air hole 207 is connected to the outside of the constant temperature tank 1.

[0028] The air hole 207 at the bottom of the inner wall of the drive shaft 201 connects to the outside and can balance the air pressure inside and outside the drive shaft 201. This prevents negative or positive pressure inside the tank due to temperature changes or liquid flow, and prevents fermentation liquid from being sucked into the drive shaft 201, resulting in residue accumulation.

[0029] like Figure 5 As shown, the outer ring of the sealing ring 206 is fixedly connected to the top of the inner wall of the drive shaft 201, and the inner ring of the sealing ring 206 abuts against and fits tightly against the outer wall of the movable rod 202. The top of the outer wall of the movable rod 202 is connected through to the center of the drive shaft 201, and the outer wall of the movable rod 202 is tightly fitted and slidably connected to the inner wall of the drive shaft 201.

[0030] The outer ring of the sealing ring 206 is fixed to the inner wall of the drive shaft 201, and the inner ring of the sealing ring 206 is tightly fitted to the outer wall of the movable rod 202, forming an effective sealing layer that can prevent liquid or impurities in the tank from seeping into the interior of the drive shaft 201 and block fermentation materials from seeping into the connection gap between the drive shaft 201 and the movable rod 202.

[0031] like Figure 5 As shown, the outer wall of the top end of the strong spring 203 abuts against the top end of the inner wall of the drive shaft 201, and the outer wall of the bottom end of the strong spring 203 abuts against the outer wall of the bottom of the movable rod 202.

[0032] The top of the powerful spring 203 abuts against the inner wall of the drive shaft 201 and the bottom abuts against the movable rod 202, continuously applying downward pressure to ensure that the movable rod 202 remains in a fixed position when not in operation, preventing the slotted fastener 204 from loosening due to vibration.

[0033] like Figure 3 , Figure 6 and Figure 7 As shown, multiple limiting components 208 are fixedly connected to the top edge of the drive shaft 201, and the multiple limiting components 208 are respectively located on both sides of the outer wall of the straight fastener 204. One side of the outer wall of the straight fastener 204 is tightly fitted with the outer wall of the limiting component 208, and the straight fastener 204 is located at the center of the top surface of the drive shaft 201.

[0034] The limiting component 208 on the top edge of the drive shaft 201 is located on both sides of the straight fastener 204, which can effectively limit the rotation of the straight fastener 204 at the top of the drive shaft 201.

[0035] like Figure 3 , Figure 6 and Figure 7 As shown, the top surface of the contact ring 3 abuts against and fits tightly against the center of the bottom surface of the cross-shaped stirring assembly 301.

[0036] The top surface of the contact collar 3 is in close contact with the bottom surface of the cross-shaped stirring assembly 301, providing stable support for the cross-shaped stirring assembly 301.

[0037] like Figure 3 As shown, the projected graphics of the cross-shaped stirring assembly 301, the straight perforation 302, and the straight groove 303 are consistent, and the bottom surface of the cross-shaped stirring assembly 301 is engaged with the inner wall of the straight groove 303.

[0038] The cross-shaped stirring assembly 301, the straight perforation 302, and the straight slot 303 have the same projected graphics, which can be quickly aligned during installation without additional calibration, thus improving assembly efficiency. In addition, the bottom surface of the cross-shaped stirring assembly 301 and the straight slot 303 are engaged and connected, which enhances the connection strength between the cross-shaped stirring assembly 301 and the drive shaft 201.

[0039] Working principle: The air hole 207 at the bottom of the inner wall of the drive shaft 201 connects to the outside, balancing the air pressure inside and outside the drive shaft 201. This prevents negative or positive pressure from being caused by temperature changes or liquid flow inside the tank, thus preventing fermentation liquid from being sucked into the drive shaft 201 and causing residue accumulation. The outer ring of the sealing ring 206 is fixed to the inner wall of the drive shaft 201, and the inner ring of the sealing ring 206 is tightly fitted to the outer wall of the movable rod 202, forming an effective sealing layer. This prevents liquid or impurities from seeping into the drive shaft 201 and blocks fermentation material from seeping into the connection gap between the drive shaft 201 and the movable rod 202. The top of the powerful spring 203 abuts against the inner wall of the drive shaft 201, and the bottom abuts against the movable rod 202, continuously applying downward pressure to ensure the movable rod 202... 2. When not in operation, the fastener 204 is kept in a fixed position to prevent it from loosening due to vibration. The limiting component 208 on the top edge of the drive shaft 201 is located on both sides of the fastener 204, which can effectively limit the rotation of the fastener 204 at the top of the drive shaft 201. The top surface of the contact collar 3 is tightly fitted with the bottom surface of the cross stirring assembly 301, providing stable support for the cross stirring assembly 301. The projection graphics of the cross stirring assembly 301, the through hole 302 and the slot 303 are consistent, which can be quickly aligned during installation without additional calibration, improving assembly efficiency. In addition, the bottom surface of the cross stirring assembly 301 is engaged with the slot 303, which enhances the connection strength between the cross stirring assembly 301 and the drive shaft 201.

[0040] 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, the scope of which is defined by the appended claims and their equivalents.
