Description
Medical material extractor Technical Field The invention belongs to the technical field of sodium alginate fiber production, and particularly relates to a medical material extractor. Background Sodium alginate, also known as sodium alginate, kelp gum, algin, alginate, is a natural polysaccharide carbohydrate extracted from kelp. The product can be widely used in food, textile, printing and dyeing, paper-making products, as thickener, emulsifier, stabilizer, adhesive, sizing agent, etc. Since the eighties, sodium alginate has been newly expanded in food applications. Sodium alginate is not only a safe food additive, but also can be used as a substrate of bionic food or therapeutic food, and can slow down the absorption of fat sugar and bile salt due to the fact that the sodium alginate is natural cellulose, and has the effects of reducing serum cholesterol, triglyceride in blood and blood sugar. Sodium alginate is a natural polysaccharide carbohydrate extracted from kelp, has the effects of reducing blood fat, blood sugar, cholesterol and the like, and is mainly used for pharmacy and health-care food at present. Meanwhile, sodium alginate is also a good dental impression material and facial mask shaping agent, and has been gradually applied to the cosmetic industry. Sodium alginate is a high-viscosity polymer compound. It differs from starch, cellulose, etc. in that it has a carboxyl group, which is a hyperuronic acid formed by glycosidic bonds of the aldehyde group of beta-D-mannuronic acid. The functional properties are strong hydrophilicity, can be dissolved in both cold water and warm water to form a very viscous uniform solution, and the formed true solution has softness which is difficult to obtain by other analogues. In the traditional process, an open type liquid storage tank is used as a cleaning replacement main body, 70% ethanol is firstly prepared by purified water and injected into the open type liquid storage tank, sodium alginate fibers are put into the open type liquid storage tank according to the weight of the mixture, a certain amount of acetic acid is added into the open type liquid storage tank, the sodium alginate fibers are left to stand for 2 hours for reaction, waste liquid is discharged and evaporated for recovery, the process is mainly used for removing impurities, then the same concentration ethanol is continuously injected for reaction for 2 hours, reaction liquid is stored and is reserved for the next group of sodium alginate fibers for primary reaction, sampling is repeated once again, evaporation and scattering are carried out after liquid discharge, then whether the requirements are met or not is checked, if the requirements are not met, the original reaction liquid is continuously injected for reaction until the original reaction is checked, finally, the sodium alginate fibers are reacted for 2 hours by using 99% ethanol, the liquid discharge is put into a centrifuge for high-speed spin-drying, the spin-dried fibers are tiled into a tunnel evaporator, and are manually taken out from the other end of the evaporator for subsequent procedures. The reaction success time per 15 kg sodium alginate fiber is 2 days according to the average replacement speed, and the efficiency is very low. In the traditional preparation process, the whole reaction process of the sodium alginate fiber is in an open environment, and the nerve system of an operator is possibly damaged in a high-concentration ethanol gas environment for a long time, so that the intelligence is reduced, the memory is reduced, or liver diseases occur, and certain damage is caused to the skin of a human body. The processes of cleaning, replacement, spin-drying, evaporation and collection of the sodium alginate fibers are all completed manually, the possibility of burning and explosion of the high-concentration ethanol gas can occur at any time during the process, the danger to human bodies and workplaces is very high, manual intervention is also required for recycling and recycling the ethanol liquid, and the requirement on the professional knowledge of operators is high and the labor intensity is very high. Therefore, it is desirable to design a medical material extractor. The invention comprises the following steps: The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a medical material extractor which solves the problems mentioned in the background art.
