Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shikimic acid water crystallization extraction, in particular to a water crystallization device and method for extracting shikimic acid from shikimic acid fermentation broth. BACKGROUND

[0002] In the existing process of extracting shikimic acid from shikimic acid fermentation broth, the crystallization reaction and solid-liquid separation are usually completed in different equipment. The crystallization process is generally carried out in a crystallization reactor, and the crystallization of shikimic acid is promoted by controlling the temperature, solvent evaporation or other parameters. After the crystallization is completed, the fermentation broth containing the crystals needs to be transferred from the crystallization reactor to the solid-liquid separation equipment (such as centrifuge or filtration device) to realize the separation of the crystals and the fermentation broth.

[0003] In actual operation, the following actual situations exist in this step-by-step operation and transfer process:

[0004] Complexity of transfer operation: After the crystallization reaction is completed, the fermentation broth needs to be transferred from the crystallization reactor to the solid-liquid separation equipment together with the crystals. This process involves multiple steps, including opening the reactor, transferring the material, cleaning the pipeline, etc., increasing the complexity of the operation.

[0005] Possibility of material loss: During the transfer process, the crystals and fermentation broth may leak due to unsealed equipment interfaces or improper operation, resulting in material loss.

[0006] Limitation of separation efficiency: Since the crystals may be damaged during the transfer process, the separation equipment may encounter incomplete separation when processing, resulting in more liquid remaining in the crystals, affecting subsequent processing.

[0007] These problems show that the existing step-by-step operation and transfer process has certain operational risks and efficiency limitations in actual application. Therefore, a device that integrates the functions of crystallization reaction and solid-liquid separation is developed to reduce or avoid the problems in the material transfer process. SUMMARY

[0008] In view of the deficiencies of the prior art, the present application provides a water crystallization device and method for extracting shikimic acid from shikimic acid fermentation broth, which solves the problem of operational risks and efficiency limitations in the actual application of the existing step-by-step operation and transfer process in the background art.

[0009] To achieve the above purpose, the present application realizes the following technical scheme: a water crystallization device and method for extracting shikimic acid from shikimic acid fermentation broth, comprising:

[0010] a reaction container;

[0011] A separating mechanism is connected with the reaction container and used for separating the crystalline from the shikimic acid fermentation liquid.

[0012] A supporting mechanism is distributed at both ends of the reaction container and used for supporting the reaction container.

[0013] A driving mechanism is installed below the reaction container and used for driving the separating mechanism.

[0014] A base is connected with the bottom of the supporting mechanism and used for limiting the driving mechanism.

[0015] Preferably, the surface of the reaction container is provided with an observation window used for observing the inside of the reaction container, and the two sides of the reaction container are installed with mounting blocks connected with iron sheets, and the two ends of the iron sheets are connected with copper sheets.

[0016] By setting the observation window on the surface of the reaction container, the crystallization process inside the reaction container can be monitored in real time, the process parameters can be adjusted in time, and the crystallization effect can be ensured.

[0017] Preferably, the two sides of the bottom of the reaction container are slidably connected with one end of a first threaded rod, one end of the first threaded rod is welded with a scraping rod, one side of the scraping rod is connected with a limiting rod, the outside of one end of the first threaded rod is screw-connected with an adjusting knob, and one end of the first threaded rod is sleeved with a spring.

[0018] By setting the first threaded rod, the scraping rod, the limiting rod, the adjusting knob and the spring, the design can effectively prevent the blockage of the inner wall of the filter cup.

[0019] Preferably, the separation mechanism comprises a magnetic rotor placed inside a filter cup, the inner surface of the filter cup is provided with a protruding structure for limiting the magnetic rotor, the outer wall of the filter cup is tightly fitted with the inner wall of the chute, the chute and the filter cup are provided with balls, the outer wall of the chute is connected with the flow guide cover, the chute and the flow guide cover are provided with an annular groove for liquid outlet, and the flow guide cover is threadedly connected with the reaction container.

[0020] By setting the magnetic rotor, the protruding structure inside the filter cup, the balls, the chute, the flow guide cover and the annular groove, the design realizes efficient mixing and separation in the crystallization process. The magnetic rotor rotates quickly in the filter cup driven by magnetic force, which can fully mix the fermentation liquid and the crystallization inducer to promote the generation of crystals. The protruding structure in the filter cup limits the magnetic rotor to ensure its stable operation. The setting of the balls reduces the friction between the filter cup and the chute, so that the filter cup can rotate more smoothly. The annular groove between the flow guide cover and the chute is used for liquid outlet to ensure that the liquid can be smoothly discharged. The threaded connection of the flow guide cover and the reaction container ensures the convenient installation and disassembly of the whole separation mechanism, further improving the convenience of operation and the efficiency of crystallization extraction.

[0021] Preferably, one end of the chute is glued with a first rotating disc, the first rotating disc is rotatably connected with a second rotating disc, one side of the second rotating disc is provided with a tab, and the surfaces of the first rotating disc and the second rotating disc are both provided with circular holes, the surface hole of the second rotating disc is aligned with the surface hole of the first rotating disc through rotating cooperation, and the first rotating disc, the second rotating disc and the filter cup are all made of PVC material and are provided with a corrosion-resistant coating on the surface.

[0022] By setting the first rotating disc, the second rotating disc and the circular holes on their surfaces, and aligning the holes with the tab, the design can effectively control the flow path of the liquid to ensure that the liquid can smoothly pass through the filter cup and be discharged during the crystallization and separation process. The first rotating disc and the second rotating disc are made of PVC material and are provided with a corrosion-resistant coating, which not only ensures the lightness of the structure, but also enhances its durability in acidic environment, prolongs the service life of the equipment, and reduces the maintenance cost of the equipment.

[0023] Preferably, the support mechanism comprises a support frame, the top of the support frame is rotatably connected with the reaction container through a rotating shaft, the two sides of the support frame are provided with baffles for limiting the curved copper sheet and the iron sheet, the outer wall of the bottom of the support frame is provided with a fixed block, the inside of the fixed block is threadedly connected with a second threaded rod, and one end of the second threaded rod is connected with an adjusting block.

[0024] The support mechanism realizes the rotary connection of the reaction container through the rotating shaft at the top of the support frame, and limits the rotation of the reaction container by the cooperation of the baffle on both sides and the bimetallic strip (copper sheet and iron sheet), so as to prevent the reaction container from being turned over in advance due to misoperation during the cooling process. The fixed block at the bottom of the support frame is threadedly connected with the second threaded rod, and the clamping and loosening of the reaction container are realized through the adjusting block, so that the reaction container can be conveniently turned over for separation operation after the crystallization is completed. This design not only ensures the stability of the reaction container during the crystallization process, but also improves the flexibility and safety of the operation.

[0025] Preferably, the driving mechanism comprises a flow guide disc, one side of the flow guide disc being communicated with the liquid outlet, the bottom of the flow guide disc being connected with a lifting seat, the inside of the lifting seat being embedded with a driving motor, the output of the driving motor being externally sleeved with a magnet, and the magnet being adsorbed with the magnetic rotor through magnetic force;

[0026] The flow guide disc is communicated with the liquid outlet, so that the liquid can be concentrated and discharged. The inside of the lifting seat at the bottom of the flow guide disc is embedded with a driving motor, and the magnet sleeved on the output end of the motor is adsorbed and driven to rotate with the magnetic rotor through magnetic force. This design not only realizes efficient mixing of the fermentation broth and the crystallization inducer during the crystallization process, but also avoids wear caused by mechanical contact through the magnetic driving mode, thereby improving the stability and service life of the device. At the same time, the design of the lifting seat facilitates the adjustment of the height of the driving mechanism, and further optimizes the operation process.

[0027] Preferably, the lifting seat is provided with protruding structures on both sides, and the protruding structures on both sides of the lifting seat are slidably connected with the grooves in the inner side of the base. By providing protruding structures on both sides of the lifting seat and slidably connecting them with the grooves in the inner side of the base, the stable lifting and precise positioning of the lifting seat are realized. This structure not only limits the movement direction of the lifting seat to ensure its vertical movement, but also improves the overall stability of the device to prevent shaking or deviation during operation.

[0035] S07. Centrifugal separation: sliding the lifting seat upward to make the flow guide disc adhere to the bottom of the second turntable, and tightening the second threaded rod to fix the height of the lifting seat; starting the driving motor to drive the magnetic rotor to rotate, and then driving the filter cup to rotate rapidly, and using the centrifugal force to throw out the moisture in the crystalline body in the filter cup; the thrown-out liquid is filtered through the filter cup, and then passes through the hole grooves on the surfaces of the first turntable and the second turntable from the annular groove, falls on the surface of the flow guide disc for collection, and is discharged through the liquid discharge port;
