Description

TECHNICAL FIELD

[0001] The present application relates to the field of glycerol glucoside preparation, more particularly, to a glycerol glucoside preparation method. BACKGROUND

[0002] Glycerol glucoside is a kind of glycoside compound formed by glycerol molecules and glucose molecules through glycosidic bond connection. In nature, there are six different stereoisomers according to the stereo configuration (alpha and beta) and the position of glycosidic bond connection. The structure with important physiological function is 2-alpha configuration. Studies have shown that it has important physiological functions such as skin moisturizing, preventing dental caries, alpha-glucosidase inhibitor, helping macromolecular stability, inhibiting the accumulation of neutral fat in adipocytes, anti-allergy and anti-cancer, and has great application potential in related fields. The main sources of glycerol glucoside are biosynthesis (including microorganisms and higher plants), chemical synthesis and enzyme catalytic synthesis. Using microalgae to produce glycerol glucoside can realize the direct conversion of carbon dioxide to glycerol glucoside product in the same cell, with high conversion efficiency and low carbon emission, so it is considered as a promising way to produce glycerol glucoside.

[0003] In the process of producing glycerol glucoside by using microalgae, the microalgae slurry rich in glycerol glucoside needs to be dehydrated first, then the low osmotic solution for extracting glycerol glucoside is added to the dehydrated slurry, and then the slurry and the glycerol glucoside aqueous solution are obtained after the separation of the algae water. The glycerol glucoside aqueous solution is also the required extraction solution. Then the membrane separation technology is used to decolorize the extraction solution. At present, the decolorization of glycerol glucoside aqueous solution mostly needs to flow into the processing cylinder through the liquid inlet end of the processing cylinder, and the processing cylinder is provided with a flat plate type module assembly processed by overlapping a plurality of horizontally arranged separation membranes. Then the flat plate type module assembly is used to decolorize the extraction solution. In the process of decolorizing the glycerol glucoside aqueous solution, the surface of the separation membrane is easy to scale, which causes the flow of the glycerol glucoside aqueous solution to be blocked and the flow rate to be slow. Under the action of pressure, the pressure on the surface of the separation membrane increases. At present, the separation membrane cannot be replaced or cleaned in time when the surface of the separation membrane scales during the decolorization of the glycerol glucoside aqueous solution, which causes the pressure on the surface of the separation membrane to increase and the separation membrane to be damaged. However, the damaged separation membrane is difficult to detect at present. This will inevitably reduce the decolorization effect of the glycerol glucoside aqueous solution and further reduce the quality of the glycerol glucoside product. SUMMARY

[0028] 3. Beneficial effects

[0029] Compared with the prior art, the advantages of the present application are that:

[0030] (1) In the process of use, when the pressure in the treatment cylinder gradually increases due to the scaling of the surface of the separation membrane and exceeds the set value, the alarm signal can be displayed to the worker in time through the troubleshooting mechanism, so that the worker can replace or clean the separation membrane for glycerol glucoside aqueous solution decolorization and scaling in time, thereby avoiding the increase of the water pressure in the treatment cylinder due to the scaling of the separation membrane, and further avoiding the damage or even damage of the separation membrane caused by the increase of the pressure on the surface of the separation membrane, improving the glycerol glucoside aqueous solution decolorization effect, and also improving the quality of glycerol glucoside product preparation.

[0031] (2) When the pressure in the treatment cylinder increases due to the scaling of the surface of the separation membrane and exceeds the elastic force of the expansion spring, the two rubber piston seats A move towards each other under the pressure of the treatment cylinder, and the gas inside the inner connecting pipe body is conducted to the inside of the transparent box body through the gas guide pipe, and then the gas pressure in the transparent box body increases and pushes the rubber piston seat B to move downward, so that the initiator head is inserted into the inside of the supersaturated sodium acetate solution layer, and then a large amount of crystals are formed in the inside of the supersaturated sodium acetate solution and heat is released, and the heat is then conducted to the heat conduction plate by the heat conduction rod, and when the heat conduction plate is heated, the heat is conducted to the nickel-titanium memory alloy wire, and when the nickel-titanium memory alloy wire is heated, the nickel-titanium memory alloy wire which is originally in a horizontal state gradually bends and pulls the blocking piece to move horizontally and gradually exposes the alarm area on the bottom plate, so that when the pressure value in the treatment cylinder increases due to the scaling of the surface of the separation membrane, a warning signal can be sent to the staff in time, and the staff can be reminded in time to replace or clean the scaling separation membrane.

[0032] (3) When the separation membrane needs to be replaced or cleaned, first stop introducing glycerol glucoside aqueous solution into the treatment cylinder, then discharge the solution that has been introduced into the treatment cylinder through the liquid outlet, since the transparent box body and the outer shell body are fixed on the base plate by magic tape, when the supersaturated sodium acetate solution in the supersaturated sodium acetate solution layer coagulates into crystals, the transparent box body and the outer shell body are removed from the base plate, then the transparent box body is placed in hot water for heating, so that the coagulated solid supersaturated sodium acetate solution layer can be changed into liquid again, so that the troubleshooting mechanism on the surface of the treatment cylinder can be reused repeatedly.

[0033] (4) After the initiator head is inserted into the inside of the supersaturated sodium acetate solution layer and the supersaturated sodium acetate solution crystallizes and solidifies, the end plate pushes the pulling rod to move horizontally, and the inclined surface on the contact block drives the wedge block to move upward, so that the rubber piston seat B can drive the initiator head to move upward and separate from the solidified supersaturated sodium acetate, so that the initiator head can be easily removed from the solidified supersaturated sodium acetate solution after the supersaturated sodium acetate solution is completely solidified.

[0034] (5) After the magic hook face tape B is adhered to the magic hair face tape B on the side wall of the outer shell body, on the one hand, the nickel-titanium memory alloy wire on the surface of the heat conduction plate can be clamped by the heat preservation layer, so that the nickel-titanium memory alloy wire is firmly attached to the surface of the heat conduction plate, and when the heat conduction plate is heated by the heat conduction rod, the heat on the heat conduction plate can be transferred to the nickel-titanium memory alloy wire in time, reducing the heat loss, and the heat preservation layer can also realize the heat preservation of the heat conduction plate and the nickel-titanium memory alloy wire, further reducing the heat loss of the heat conduction plate and the nickel-titanium memory alloy wire.

[0066] When the pressure in the processing cylinder increases due to the scaling of the surface of the separation membrane and exceeds the elastic force of the expansion spring 14, the two rubber piston seats A 15 move towards each other under the pressure of the processing cylinder, and the gas inside the inner connecting pipe body 11 is conducted to the inside of the transparent box body 200 through the gas guide pipe, and then the gas pressure in the transparent box body 200 increases and pushes the rubber piston seat B 202 to move downward, so that the trigger head 203 is inserted into the inside of the supersaturated sodium acetate solution layer, and then a large amount of crystals are formed in the supersaturated sodium acetate solution and heat is released, and the heat is then conducted to the heat conduction plate 8 through the heat conduction rod 201, and when the heat conduction plate 8 is gradually heated uniformly, the temperature is near 40 degrees, and then the heat is conducted to the nickel-titanium memory alloy wire 7, and the nickel-titanium memory alloy wire 7 is treated at a high temperature of 500℃ to form a flat S-shaped structure, and the nickel-titanium memory alloy wire 7 becomes soft at 10℃ and can be arbitrarily shaped, and the nickel-titanium memory alloy wire 7 is straightened at 10℃ and is reshaped at 33-38℃, and when the nickel-titanium memory alloy wire 7 is heated, the originally horizontal nickel-titanium memory alloy wire 7 gradually becomes zigzag and pulls the baffle 4 to move horizontally and gradually exposes the alarm area on the bottom plate, and when the baffle 4 is pulled during the reshaping of the nickel-titanium memory alloy wire 7, when the baffle 4 moves to the covering cloth 3, there is a gap between the baffle 4 and the covering cloth 3, so the baffle 4 can smoothly pass through the covering cloth 3 fixed on the outer shell 18, and when the pressure value in the processing cylinder increases due to the scaling of the surface of the separation membrane, an alarm signal can be sent to the staff in time, and the staff can be reminded to replace or clean the scaling separation membrane in time.

[0067] When the separation membrane needs to be replaced or cleaned, first stop introducing glycerol glucoside aqueous solution into the processing cylinder, then discharge the solution that has been introduced into the processing cylinder through the liquid outlet, since the transparent box body 200 and the outer shell 18 are fixed on the base plate 1 by magic tape, when the supersaturated sodium acetate solution in the supersaturated sodium acetate solution layer coagulates into crystals, the transparent box body 200 and the outer shell 18 are removed from the base plate 1, then the transparent box body 200 is placed in hot water for heating, so that the coagulated solid supersaturated sodium acetate solution layer can be changed into liquid again, so that the troubleshooting mechanism on the surface of the processing cylinder can be reused repeatedly for many times.

[0068] After the trigger head 203 is inserted into the inside of the supersaturated sodium acetate solution layer and the supersaturated sodium acetate solution is crystallized and solidified, the end plate 207 pushes the pulling rod 206 to move horizontally, and the inclined surface on the contact block 205 drives the wedge block 204 to move upward, so that the rubber piston seat B 202 can drive the trigger head 203 to move upward and separate from the solidified supersaturated sodium acetate solution, so that the trigger head 203 can be easily removed from the solidified supersaturated sodium acetate solution after the supersaturated sodium acetate solution is completely solidified.

[0069] After the magic hook surface B23 is adhered to the magic hair surface B on the side wall of the outer shell 18, on the one hand, the nickel-titanium memory alloy wire 7 on the surface of the heat conduction plate 8 can be clamped by the heat preservation layer 24, so that the nickel-titanium memory alloy wire 7 is firmly attached to the surface of the heat conduction plate 8. When the heat conduction plate 8 is heated by the heat conduction rod 201, the heat on the heat conduction plate 8 can be transmitted to the nickel-titanium memory alloy wire 7 in time, reducing the heat loss. At the same time, the heat preservation layer 24 can also realize the heat preservation treatment of the heat conduction plate 8 and the nickel-titanium memory alloy wire 7, further reducing the heat loss of the heat conduction plate 8 and the nickel-titanium memory alloy wire 7.

[0070] The above description is only the preferred embodiment of the present application; the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical solution and the improvement concept of the present application, which should be covered in the protection scope of the present application.
