Description

Technical Field

[0001] The utility model provides separation and purification equipment for producing brown algae oligosaccharide, belonging to the technical field of brown algae oligosaccharide production. Background Art

[0002] As an important functional raw material, brown algae oligosaccharide has broad application prospects in the fields of food, medicine and cosmetics. It has multiple biological activities such as anti-oxidation, anti-inflammatory, anti-tumor, blood sugar regulation and blood lipid reduction, so it has attracted widespread attention. At present, the preparation of brown algae oligosaccharide is mainly obtained by extracting it from brown algae and then enzymatically hydrolyzing it.

[0003] The basic process is to enzymatically hydrolyze brown algae to prepare brown algae oligosaccharide solution, and then the brown algae oligosaccharide solution is separated and purified through the following steps: microfiltration to remove impurities visible to the naked eye, ultrafiltration to remove large molecular proteins, etc., sodium filtration to remove excess inorganic salts while concentrating, and finally obtain pure brown algae oligosaccharide concentrate.

[0004] When microfiltration is used to remove impurities visible to the naked eye, a filter membrane element is usually used. After the membrane element has been used for a period of time, various components in the feed liquid may form blockages inside and on the surface of the membrane. The main source of contamination to the membrane in the feed liquid is organic matter. If these pollutants adsorbed on the surface and inside of the membrane are not removed in time, the filtration performance of the membrane will be greatly affected, mainly manifested as a significant attenuation of the filtration flux. Therefore, the membrane must be cleaned, regenerated or replaced regularly to restore the filtration performance of the membrane element. However, cleaning or replacing the membrane is often troublesome, requiring the membrane element to be disassembled from the purification equipment, and then the membrane must be cleaned or replaced, and the separation and purification needs to be suspended for a long time, delaying the separation and purification efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is that when producing brown algae oligosaccharides, it is troublesome to clean or replace the filter membrane element, which delays the separation and purification process and reduces the purification efficiency.

[0008] As an improvement, a cleaning pump is provided in the cleaning box, and the output pipe of the cleaning pump is connected to the cleaning nozzle; a controller connected to the cleaning pump circuit is provided on one side of the cleaning box, and the controller is connected to the rotating motor circuit.

[0009] As an improvement, a fixed cylinder is fixedly connected to one side of the purification cylinder, and a screw rod is rotatably arranged inside the fixed cylinder; a lifting motor connected to the controller circuit is arranged above the fixed cylinder, and the output shaft of the lifting motor is fixedly connected to the screw rod; a lifting block is threadedly connected to the screw rod.

[0011] As an improvement, a water receiving box located below the rotating plate is provided on one side of the purification cartridge.

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] according to Figure 1-5 As shown: the utility model provides a separation and purification device for producing brown algae oligosaccharides: comprising a purification cylinder 1, the upper end of the purification cylinder 1 is connected to a liquid inlet pipe 2, and the lower end of the purification cylinder 1 is connected to a liquid outlet pipe 8; a groove 7 is provided in the purification cylinder 1, and a rotating plate 6 is rotatably arranged in the groove 7; two corresponding filter membranes 14 are arranged on the rotating plate 6, and one of the filter membranes 14 is located in the purification cylinder 1; a cleaning box 3 is fixedly connected to the side of the purification cylinder 1, and a cleaning nozzle 4 corresponding to the filter membrane 14 is arranged at the bottom of the cleaning box 3; a slot 13 is provided around the filter membrane 14, and an insert 17 inserted into the slot 13 is slidably arranged in the purification cylinder 1.

[0022] By rotating the rotating plate 6, the filter membrane 14 element can be quickly replaced without disassembling the purification equipment. At the same time, a cleaning nozzle 4 is provided to rinse the replaced filter membrane 14, which will not delay the separation and purification process for a long time and can ensure the purification efficiency.

[0023] A fixed block 11 is fixedly connected to one side of the purification cartridge 1, and a rotating motor 10 is arranged on the fixed block 11; a rotating shaft 9 is fixedly connected to the output shaft of the rotating motor 10, and the rotating shaft 9 is fixedly connected to the rotating plate 6.

[0030] Principle of the utility model

[0031] like Figure 1-2 As shown, when the present application is working normally, the brown algae oligosaccharide enzymatic hydrolysis solution flows from the liquid inlet pipe 2 into the insert 17 in the purification cylinder 1, enters the bottom of the purification cylinder 1 after being filtered by the filter membrane 14, and flows out from the outlet pipe, which is convenient for more precise filtration.

[0032] When the filter membrane 14 needs to be replaced, Figure 4 As shown, when there is no algae oligosaccharide enzymatic hydrolysis solution in the insert 17, the lifting motor 21 is started by the controller 12, and the insert 17 moves upward and disengages from the slot 13 under the drive of the lifting block 19. At this time, the controller 12 delays the control of the rotating motor 10 to start, so that the rotating plate 6 rotates, so that the two filter membranes 14 on the rotating plate 6 are swapped, and the replacement of the filter membrane 14 is quickly completed; the filter membrane 14 to be replaced or cleaned is located below the cleaning nozzle 4, and the new filter membrane 14 is located in the purification cylinder 1. The lifting motor 21 is reversed to reinsert the insert 17 into the slot 13, thereby ensuring that the algae oligosaccharide enzymatic hydrolysis solution will not flow out of the groove 7. At this time, the separation and purification of the algae oligosaccharide enzymatic hydrolysis solution can be continued directly, as shown in FIG. Figure 3 The controller 12 controls the cleaning pump 18 to start, and the replaced filter membrane 14 is rinsed through the cleaning nozzle 4, and the cleaned wastewater flows into the water receiving box 5, which is also convenient for the staff to replace the filter membrane 14. The process of cleaning and replacing the filter membrane 14 will not affect the purification process of the purification cartridge 1 at this time, and the separation and purification efficiency of brown algae oligosaccharides can be guaranteed.
