Description

Technical Field

[0001] This utility model relates to the field of fermentation broth extraction technology, and in particular to a fermentation broth extraction and separation device. Background Technology

[0002] Fermentation broth refers to a mixed liquid produced during microbial fermentation that contains various substances such as the target product, microbial cells, unconsumed culture medium components, and metabolic byproducts. In order to separate and purify the desired target product from the fermentation broth, it is necessary to perform extraction treatment on the fermentation broth.

[0003] In the field of fermentation broth extraction and separation technology, existing extraction and separation devices have many shortcomings in practical applications. The heating structure design of traditional devices is not reasonable enough. The heating element is in direct contact with the material or is too close, which can easily lead to excessively high local temperature, affecting the extraction effect. Moreover, the heating range is limited, making it difficult to achieve uniform heating of the material, thereby reducing the extraction efficiency and product quality. Therefore, this application proposes a fermentation broth extraction and separation device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fermentation broth extraction and separation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fermentation broth extraction and separation device, comprising an outer barrel with an opening at the top, and the diameter of the top of the inner wall of the outer barrel being smaller than the diameter of its bottom.

[0006] Optionally, a cylindrical protective mesh frame is installed between the top and bottom of the inner wall of the outer tub. The inner diameter of the protective mesh frame is the same as the inner diameter of the opening at the top of the outer tub. Multiple heating elements are located between the protective mesh frame and the outer tub. Four support columns are installed in a circular array at the bottom of the outer tub. When the sealing plate is in contact with the top of the outer tub, the bottom of the inner tub is in contact with the top of the support columns.

[0007] Optionally, a filter assembly is installed at the top of the lid, and a second exhaust pipe is fixedly installed at the top of the lid. A second air guide pipe made of rubber is fitted onto the second exhaust pipe. A first exhaust pipe communicating with the interior of the outer barrel is fixedly installed at the top of the outer barrel, and a first air guide pipe made of rubber is fitted onto the first exhaust pipe.

[0008] Optionally, the filter assembly includes an injection pipe, a filter funnel, and a cap. The injection pipe passes through the cap, the filter funnel is placed at the top of the injection pipe, and an extension plate is provided at the top of the outer side of the filter funnel. The diameter of the extension plate is the same as the diameter of the injection pipe, and the cap is threaded onto the top of the injection pipe.

[0009] Optionally, the top of the rotating rod is provided with a lower cross lock, and the side wall of the motor output end is provided with a slot. The linkage assembly includes a rotating part and a linkage rod. The top of the linkage rod is provided with a rod groove, and a limit plate is fixedly installed at the opening of the rod groove. The rod groove at the top of the linkage rod is sleeved on the output end of the motor, and the limit plate is inserted through the slot. The lower half of the rotating part is rotatably sleeved on the linkage rod, and the upper half of the rotating part is threadedly sleeved on the output end of the motor. The bottom of the linkage rod is provided with an upper cross lock. The top and bottom of the connecting rod are both provided with cross slots. The cross slot at the top of the connecting rod can be engaged with the upper cross lock at the bottom of the linkage rod, and the cross slot at the bottom of the connecting rod can be engaged with the lower cross lock at the top of the rotating rod.

[0010] Optionally, a limit ring is fixedly installed at the top of the side wall of the linkage rod, and an annular groove is opened on the inner wall of the lower half of the rotating part, and the connecting ring is located in the annular groove and can rotate inside it.

[0011] Optionally, multiple sets of locking assemblies are installed in a circular array at the top edge of the outer tub. The locking assembly includes a screw, a pressure plate, and a nut. An annular groove is provided at the top edge of the sealing plate. The screw is installed on the top of the outer tub. One end of the pressure plate is movably sleeved on the screw.

[0012] Optionally, a water inlet pipe communicating with the interior is fixedly installed on the top of the outer barrel side wall, and a drain pipe communicating with the interior is fixedly installed on the bottom of the outer barrel side wall. Rectangular openings are provided on the top of the side walls of both support plates.

[0013] The beneficial effects of this utility model are: Water is injected into the outer barrel through the inlet pipe, and multiple electric heating tubes can heat the water. The water bath heating method achieves uniform heating of the inner barrel, effectively preventing material deterioration caused by excessive local temperature. The protective mesh frame can protect the electric heating tubes, while the support column can ensure that the bottom of the inner barrel is in full contact with the heated water, further improving the uniformity of heat distribution, extraction efficiency and the purity of the target product.

[0014] The rotating rod and the connecting rod, as well as the connecting rod and the linkage assembly, are engaged and locked together by a cross-shaped latch and a cross-shaped slot. The linkage rod sleeved on the motor output end can change its height as the rotating part rotates, thereby separating the bottom end of the linkage rod from the top end of the connecting rod. This allows the lid to be removed from the top of the inner bucket. After unlocking the latch assembly, the inner bucket can be removed from the outer bucket, facilitating cleaning or maintenance of both the outer bucket and the inside of the inner bucket, and reducing the workload of the staff.

[0015] The sealing plate on the outside of the inner barrel fits tightly against the top of the outer barrel. With the pressing action of the locking assembly, the sealing performance of the device can be effectively enhanced to prevent leakage of fermentation liquid or entry of external impurities. The outer barrel and the inner barrel are respectively equipped with a first exhaust pipe and a second exhaust pipe, and the gas is guided out through the first and second gas guide pipes made of rubber to avoid abnormal internal pressure caused by gas accumulation during the extraction process and reduce safety hazards.

[0016] The filter components (injection tube, filter funnel, and cap) at the top of the lid can directly filter impurities when adding fermentation broth, reducing subsequent separation steps and improving the purity of the target product. The detachable design of the filter funnel and cap also facilitates cleaning and replacement, ensuring the stability of the filtration effect. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-8 This utility model provides a technical solution: a fermentation broth extraction and separation device, including an outer barrel 1, the top of which is open, and the diameter of the top of the inner wall of the outer barrel 1 is smaller than the diameter of its bottom. Multiple electric heating tubes 14 are arranged in a circular array inside the outer barrel 1. An inner barrel 2 is provided inside the outer barrel 1, and a horizontal fixing plate 28 is installed at the opening at the top of the inner barrel 2. A through-hole is opened at the center of the fixing plate 28, and a second bearing is fixedly installed in the through-hole. A rotating rod 29 located in the inner barrel 2 is fixedly inserted into the second bearing. Multiple sets of stirring rods are equidistantly installed on the rotating rod 29. A barrel lid 2 is closed at the top of the inner barrel 2. 2. A through hole is provided in the center of the lid 22. A first bearing 223 is fixedly installed in the through hole. A connecting rod 224 is vertically inserted into the first bearing 223. The bottom end of the connecting rod 224 is engaged with the top end of the rotating rod 29. A sealing plate 21 is fixedly sleeved on the outside of the inner barrel 2. The bottom of the sealing plate 21 is in contact with the top of the outer barrel 1. Support plates 23 are installed at both ends of the top of the sealing plate 21. A top plate 24 is fixedly installed on the top of the two support plates 23. A motor 25 is installed at the center of the top of the top of the top plate 24. The output end of the motor 25 is provided with a linkage component 26 that is engaged with the top end of the connecting rod 224.

[0020] The nested structure of the outer barrel 1 and the inner barrel 2, combined with the ring array of electric heating tubes 14, achieves uniform heating and avoids local overheating. The interlocking design of the rotating rod 29 and the connecting rod 224, and the connecting rod 224 and the linkage component 26, makes it easy to disassemble and assemble the stirring and power transmission components, reducing maintenance difficulty. The sealing plate 21 fits against the top of the outer barrel 1 to enhance the sealing performance. The rotation of the rotating rod 29 driven by the motor 25 and the rotation of multiple sets of stirring rods can improve the mixing efficiency of the fermentation liquid. The overall structure takes into account the uniformity of heating, the convenience of operation and the stability of sealing.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, a cylindrical protective mesh frame 13 is installed between the top and bottom of the inner wall of the outer barrel 1. The inner diameter of the protective mesh frame 13 is the same as the inner diameter of the opening at the top of the outer barrel 1. Multiple heating elements 14 are located between the protective mesh frame 13 and the outer barrel 1. Four support columns 15 are installed in a circular array at the bottom of the outer barrel 1. When the sealing plate 21 is in contact with the top of the outer barrel 1, the bottom of the inner barrel 2 is in contact with the top of the support columns 15. The protective mesh frame 13 isolates the heating elements 14 from the inner barrel 2, which avoids the problem of local high temperature caused by direct contact between the heating elements 14 and the material, and protects the heating elements 14 from collision damage. The support columns 15 provide stable support for the inner barrel 2 inserted into the outer barrel 1, ensuring that the bottom of the inner barrel 2 can also be heated evenly, thus improving heating efficiency.

[0022] like Figure 1 , Figure 2 and Figure 6 As shown, a filter assembly 27 is installed at the top of the lid 22, and a second exhaust pipe 221 is also fixedly installed at the top of the lid 22. A second air guide pipe 222 made of rubber is fitted onto the second exhaust pipe 221. A first exhaust pipe 16 communicating with the interior of the outer barrel 1 is fixedly installed at the top of the outer barrel 1. A first air guide pipe 17 made of rubber is fitted onto the first exhaust pipe 16. The filter assembly 27 can pre-filter impurities when adding materials, thereby improving the initial purity of the fermentation liquid. The lid 22 and the outer barrel 1 are respectively provided with a second exhaust pipe 221 and a first exhaust pipe 16, which can promptly discharge the gas in their respective spaces and avoid abnormal pressure.

[0023] like Figure 6 and Figure 8As shown, the filter assembly 27 includes an injection pipe 271, a filter funnel 272, and a cap 273. The injection pipe 271 passes through the cap 22. The filter funnel 272 is placed at the top of the injection pipe 271. An extension plate is provided at the top of the outer side of the filter funnel 272, and the diameter of the extension plate is the same as the diameter of the injection pipe 271. The cap 273 is threaded onto the top of the injection pipe 271. The filter funnel 272 is stably placed at the top of the injection pipe 271 through the extension plate, realizing immediate filtration when materials are added and reducing the entry of impurities. The threaded connection design of the cap 273 can seal the injection pipe 271 when no materials are added, preventing materials from splashing out or external impurities from entering during the extraction process. The structure is simple and the switching between filtration and sealing functions is convenient.

[0024] like Figure 5 and Figure 7 As shown, the top of the rotating rod 29 has a lower cross latch 291, and the side wall of the output end of the motor 25 has a slot 251. The linkage assembly 26 includes a rotating part 261 and a linkage rod 262. The top of the linkage rod 262 has a rod groove, and a limit plate 264 is fixedly installed at the opening of the rod groove. The rod groove at the top of the linkage rod 262 is sleeved on the output end of the motor 25, and the limit plate 264 is inserted through the slot 251. The lower half of the rotating part 261 is rotatably sleeved on the linkage rod 262, and the upper half of the rotating part 261 is threadedly sleeved on the output end of the motor 25. The bottom end of the linkage rod 262 has an upper cross latch 263. The top and bottom ends of the connecting rod 224 both have cross slots, and the connecting rod 224... The top cross slot can engage with the upper cross latch 263 at the bottom of the linkage rod 262, and the bottom cross slot of the connecting rod 224 can engage with the lower cross latch 291 at the top of the rotating rod 29. The engagement structure of the upper cross latch 263, the lower cross latch 291 and the cross slot makes the connection between the rotating rod 29, the connecting rod 224 and the linkage rod 262 firm and easy to disassemble and assemble, making it easy to remove the lid 22 from the top of the inner barrel 2. The cooperation between the limiting plate 264 and the slot 251 in the linkage assembly 26 ensures that the motor 25 transmits power stably to the connecting rod 224 through the linkage rod 262. The threaded connection of the rotating part 261 further strengthens the connection between the linkage rod 262 and the motor 25, improving the reliability of power transmission.

[0025] like Figure 7 As shown, a limiting ring 265 is fixedly installed at the top of the side wall of the linkage rod 262, and an annular groove 266 is opened on the inner wall of the lower half of the rotating part 261. The connecting ring is located in the annular groove 266 and can rotate inside it. The cooperation between the limiting ring 265 and the annular groove 266 restricts the axial displacement of the linkage rod 262 and the rotating part 261, ensuring the structural stability of the linkage assembly 26 during power transmission.

[0026] like Figure 1 and Figure 2As shown, multiple sets of locking assemblies 3 are installed in a circular array at the top edge of the outer barrel 1. The locking assembly 3 includes a screw 31, a pressure plate 32, and a nut 33. An annular groove 211 is provided at the top edge of the sealing plate 21. The screw 31 is installed on the top of the outer barrel 1. One end of the pressure plate 32 is movably sleeved on the screw 31. A limiting block that matches the annular groove 211 and is located inside it is provided at the bottom of the other end of the pressure plate 32. The nut 33 is threaded onto the top of the screw 31, and the bottom of the nut 33 abuts against the top of the pressure plate 32. Through the cooperation of the screw 31, the pressure plate 32, and the nut 33, the locking assembly 3 can tightly press the sealing plate 21 against the top of the outer barrel 1, significantly enhancing the sealing performance of the connection between the inner barrel 2 and the outer barrel 1, preventing leakage of fermentation liquid and entry of external impurities, and ensuring the stability of the extraction environment.

[0027] like Figure 1 and Figure 5 As shown, an inlet pipe 11 communicating with the interior is fixedly installed on the top of the side wall of the outer tub 1, and a drain pipe 12 communicating with the interior is fixedly installed on the bottom of the side wall of the outer tub 1. Rectangular openings are provided on the top of the side walls of the two support plates 23. The inlet pipe 11 and the drain pipe 12 facilitate the addition or discharge of a medium (such as hot water) for auxiliary heating into the outer tub 1, realizing flexible adjustment of the heating mode. The rectangular openings of the support plates 23 can be used as a point of force for lifting the inner tub 2, providing convenience for the operation of picking up and putting down the inner tub 2 and simplifying the use process of the device.
