Description

Technical Field

[0001] The utility model relates to the technical field of sophorolipid preparation, and particularly relates to an extraction device for sophorolipid raw materials. Background Technique

[0002] Sophorolipid is a secondary metabolite of microorganisms produced by Candida yeast using sugars and vegetable oils as carbon sources through a fermentation process under certain conditions. It is a glycolipid biosurfactant and is widely used in fields such as food, cosmetics, and environmental protection. Sophorolipid has general properties such as solubilization, emulsification, wetting, foaming, dispersion, and reduction of surface tension possessed by conventional surfactants. The production process of sophorolipid includes two processes: fermentation and extraction. The fermentation process is completely a microbial metabolism process, and the raw materials are natural plant-derived raw materials. The extraction process uses a physical extraction process without organic solvents. There are no chemical reactions and chemical component additions in all process steps, ensuring the overall process is green and environmentally friendly.

[0003] After the fermentation of sophorolipid is completed, purification treatment is required to extract the sophorolipid stock solution from the raw materials. Existing extraction devices use physical extraction processes such as natural precipitation, centrifugation, and membrane filtration. However, the extraction efficiency of a single extraction method is low, and repeated operations are required, resulting in complex operations and long time consumption. There is an urgent need for a new type of extraction device to solve the above problems. Content of the Utility Model

[0027] Embodiment:

[0028] As Figures 1 to 6 shown, a sophorolipid raw material extraction device includes a tank body 8 and an upper cover 7. The upper cover 7 is hermetically connected to the upper side of the tank body 8. A ceramic cylindrical filter membrane 17 is provided inside the tank body 8. A discharge pipe 10 is fixedly provided at the bottom of the tank body 8, and the upper end of the discharge pipe 10 communicates with the bottom of the ceramic cylindrical filter membrane 17. A first valve 9 is assembled on the discharge pipe 10. A sealing plug plate 13 with a stepped structure is provided inside the upper cover 7 corresponding to the ceramic cylindrical filter membrane 17. A hydraulic cylinder 1 is assembled on the upper side of the upper cover 7. The lower end of the hydraulic cylinder 1 extends into the upper cover 7 and is fixedly connected to the sealing plug plate 13. A backwashing mechanism 5 is provided inside the tank body 8. A high-pressure air pump 2 is assembled on the upper cover 7 on the left side of the hydraulic cylinder 1. The output end of the high-pressure air pump 2 is connected with a high-pressure air pipe 3, and the end of the high-pressure air pipe 3 penetrates through the tank body 8 and extends into the ceramic cylindrical filter membrane 17. A material pump 6 is assembled on the upper cover 7 on the right side of the hydraulic cylinder 1. The output end of the material pump 6 is connected with a feed hose 14. The input end of the material pump 6 is connected to an external sophorolipid raw material storage device through a pipeline. A feed flow channel 18 is opened inside the sealing plug plate 13, and the lower end of the feed hose 14 is inserted into the feed flow channel 18. This design solves the problems that the existing extraction devices usually adopt a single physical extraction process, the single extraction method has low extraction efficiency, requires repeated operations, is complex in operation, and takes a long time.

[0029] In this embodiment, fixing rings 16 are fixedly arranged on both the upper and lower sides of the circumferential surface of the ceramic cylindrical filter membrane 17. The fixing rings 16 are fixedly connected to the inner wall of the tank body 8 through multiple groups of radially structured support rods. The two sets of fixing rings 16 provided realize the fixation of the ceramic cylindrical filter membrane 17, enhance the stability of the ceramic cylindrical filter membrane 17 in the tank body 8, and prevent the ceramic cylindrical filter membrane 17 from shifting and shaking.

[0030] In this embodiment, the bottom of the tank body 8 is arranged as an upwardly convex arc structure. The upwardly convex arc structure is beneficial to the flow and discharge of the materials at the bottom of the tank body 8, reduces the accumulation and retention of the materials at the bottom, and helps to improve the extraction efficiency. A discharge pipe 11 is fixedly arranged near the left edge of the bottom of the tank body 8. A second valve 12 is assembled on the discharge pipe 11. The discharge pipe 11 is used to discharge the materials at the bottom of the tank body 8. The second valve 12 realizes the precise control of the discharge process. By opening or closing the valve, the discharge speed and discharge amount can be flexibly adjusted.

[0031] In this embodiment, a check valve 4 is assembled on the high-pressure air pipe 3. The check valve 4 can prevent the backflow of the sophorolipid raw materials inside the ceramic cylindrical filter membrane 17, helps to maintain the stability of the internal pressure of the ceramic cylindrical filter membrane 17, and improves the operation stability of the entire device. An electromagnetic valve 15 is assembled on the feed hose 14. The electromagnetic valve 15 is used to precisely control the conveying of the raw materials. By adjusting the opening and closing state of the electromagnetic valve 15, the precise control of the raw material flow rate and flow velocity can be realized. At the same time, the feed hose 14 can be closed through the electromagnetic valve 15 to prevent the gas in the ceramic cylindrical filter membrane 17 from leaking out through the feed hose 14, which is beneficial to maintaining the internal pressure of the ceramic cylindrical filter membrane 17.

[0032] In this embodiment, the backwashing mechanism 5 includes a washing component 51, an electric push rod 52, a bottom plate 53, a high-pressure water pump 54, a high-pressure water pipe 55 and a water inlet hose 56. There are two sets of washing components 51, which are symmetrically arranged on the left and right sides of the ceramic cylindrical filter membrane 17 inside the tank body 8. Electric push rods 52 are symmetrically assembled on both the left and right sides of the circumferential surface of the tank body 8. The output end of the electric push rod 52 extends into the tank body 8 and is fixedly connected to the washing component 51. A bottom plate 53 is fixedly arranged on the rear side of the circumferential surface of the tank body 8. A high-pressure water pump 54 is installed on the bottom plate 53. The output end of the high-pressure water pump 54 is connected to a high-pressure water pipe 55. Water inlet hoses 56 are arranged on both the left and right sides of the high-pressure water pipe 55 and are connected to the washing component 51. The backwashing mechanism 5 directly washes the surface of the ceramic cylindrical filter membrane 17 with high-pressure water flow, can quickly remove the residues on the ceramic cylindrical filter membrane 17, restore the filtering performance of the ceramic cylindrical filter membrane 17, reduce the risk of blockage and wear of the ceramic cylindrical filter membrane 17, and thus extend the service life of the ceramic cylindrical filter membrane 17.

[0033] In this embodiment, the flushing assembly 51 includes an enclosing plate 511, a buffer chamber 512, high-pressure nozzles 513 and grooves 515. The enclosing plate 511 is arranged in a semi-cylindrical tubular structure. After two groups of enclosing plates 511 are closed and connected, a tubular structure with a closed side is formed. Grooves 515 are formed on the inner side surface of the enclosing plate 511. A plurality of groups of high-pressure nozzles 513 are evenly arranged at the bottom of the grooves 515. A buffer chamber 512 is formed inside the enclosing plate 511. Both the high-pressure nozzles 513 and the water inlet hose 56 are communicated with the buffer chamber 512. The flushing assembly 51 sprays high-pressure water flow onto the outer surface of the ceramic tubular filter membrane 17 at a high speed through the high-pressure nozzles 513, which can quickly remove the residues on the ceramic tubular filter membrane 17 and improve the flushing efficiency. At the same time, the arranged enclosing plate 511 enables the flushing operation to be carried out in a closed space, avoiding the splashing of high-pressure water flow and ensuring the flushing effect. In addition, the uniform distribution of the high-pressure nozzles 513 also ensures the uniformity of the flushing operation, enabling the high-pressure water flow to completely cover the surface of the ceramic tubular filter membrane 17 and ensuring the flushing quality.

[0034] In this embodiment, a layer of sealing gasket 514 is pasted on the opposite surfaces of the two groups of enclosing plates 511. The arranged sealing gasket 514 ensures the sealing performance of the connection between the two groups of enclosing plates 511 after being closed.

[0035] The working principle of this sophorolipid raw material extraction device: In actual use, first close the first valve 9, open the second valve 12 and the solenoid valve 15 on the feed hose 14, and then start the material pump 6. The material pump 6 sucks the raw materials from the external sophorolipid raw material storage device through the pipeline and transports them to the feed flow channel 18 inside the sealing plug plate 13 via the feed hose 14. The raw materials flow out from the feed flow channel 18 and enter the inside of the ceramic tubular filter membrane 17. The raw materials are filtered inside the ceramic tubular filter membrane 17. The effective components such as sophorolipids are intercepted by the filter membrane, while other substances in the raw materials flow out through the filter membrane and are finally discharged through the discharge pipe 11 at the bottom of the tank body 8. During the filtering process, start the hydraulic cylinder 1. By controlling the hydraulic cylinder 1, the sealing plug plate 13 is pressed down to be in close contact with the upper end of the ceramic tubular filter membrane 17 to form a seal. Then the high-pressure air pump 2 works, and high-pressure gas is conveyed into the inside of the ceramic tubular filter membrane 17 through the high-pressure air pipe 3 to increase the pressure inside the filter membrane, accelerate the filtering speed of the raw materials, promote the filtering of the raw materials, and thus realize the rapid extraction and filtering treatment of the raw materials;

[0036] After the filtration is completed, open the first valve 9 to discharge the sophorolipid filtered out in the ceramic cylindrical filter membrane 17 through the discharge pipe 10. Then start the backwashing mechanism 5 for cleaning. The electric push rod 52 works to push the washing component 51 close to the ceramic cylindrical filter membrane 17, and the two groups of enclosing plates 511 are hermetically sleeved on the outer side of the ceramic cylindrical filter membrane 17. Then the high-pressure water pump 54 works to convey high-pressure water flow into the buffer cavity 512 in the enclosing plate 511 through the high-pressure water pipe 55 and the water inlet hose 56. The high-pressure water flow is sprayed onto the outer surface of the ceramic cylindrical filter membrane 17 at a high speed from the high-pressure nozzle 513 to perform backwashing on the ceramic cylindrical filter membrane 17 and remove the residues on the inner wall of the ceramic cylindrical filter membrane 17.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
