The invention discloses a resurrection factor purification and extraction process for improving injection-type autologous fat survival rate. The process includes the steps: (a) collecting whole blood samples; (b) separating the whole blood samples; (c) fermenting the whole blood samples; (d) freezing fermentative supernatant liquid; (e) enabling whole blood sample cells to resuscitate; (f) performing purification and extraction for resurrection factors: adding liquid after standing into a centrifuging tube, performing secondary centrifugation for the liquid in a centrifugal machine, standing in the constant temperature environments after centrifugation, removing blood plasma on the upper layer of the centrifuging tube, adding new blood samples, and enabling sediment blood platelets to re-suspend to obtain the resurrection factors. According to the process, PRP (platelet-rich plasma) of autologous fat injection can be effectively extracted, extracting efficiency of the PRP from the cells is greatly improved, activities after autologous fat injection can be ensured, autologous fat injection operations are safer and more reliable, and the process is worthy of popularization.

The invention belongs to the technical field of organic chemistry, in particular relating to a purification method of vitamins, comprising the following steps: resolving the crude vitamin K3 in an organic solvent, such as benzene, ethanol and carbon tetrachloride and the like at the temperature of 70-90 DEG C by adopting a recrystallization technical process; adding activated carbon, stirring and resolving for 3-5 hours, filtering, concentrating the filter, and evaporating excessive organic solvent; stirring the residual mixed liquor at the condition of 0-5 DEG C; and separating out the crystallization; placing the solid-liquid mixture in a centrifugal machine for centrifugation to reach separation of the solid and the liquid; and drying the solid to obtain more than 96% of the pure product vitamin K3. The organic solvent is concentrated and recovered to be recycled. The purification method of the invention has the advantages of high purity, low cost and basic nonexistence of three wastes and the like, and is beneficial for industrial implementation.

The invention discloses a multi-stage type helical screen continuous centrifuge. The multi-stage type helical screen continuous centrifuge comprises a case, a differential transmission device and a separating device. The differential transmission device is arranged on one side of the case, and the separating device is arranged in the case; the differential transmission device comprises a differential mechanism, a bearing box and a belt transmission device; the separating device comprises three rotation baskets connected sequentially and three helical pushing devices arranged in the three rotation baskets, respectively; the first stage of rotation basket and the third stage of rotation basket are of conical rotation baskets, and the small openings thereof face the differential transmission device, the second stage of rotation basket is of a horizontal rotation basket; the direction of each helical pushing device is the same as the direction of the corresponding rotation basket; the first stage of rotation basket and the corresponding helical pushing device are fixedly connected with two output shafts of the differential mechanism, respectively; a vertical partition board is further arranged out of the connection part of the first stage of rotation basket and the second stage of rotation basket. By utilizing the centrifuge, the dehydration of difficult-to-process materials can be realized effectively, mother liquor and cleaning fluid can be separated completely, the structure is simple, the dehydration effect is better, the processing efficiency is higher, and the energy consumption is lower.

The invention belongs to the technical field of material centrifugation, and discloses a horizontal spiral discharging centrifuge. The horizontal spiral discharging centrifuge is provided with a fixedbase, fixed shafts are symmetrically and fixedly installed at the upper end of the fixed base, a rotating device is installed on the two fixed shafts, the outer part of the rotating device is provided with spiral fan blades, the outer parts of the spiral fan blades are sleeved with a cylindrical outer shell, a solid collecting plate which is matched with the spiral fan blades is arranged on the inner wall of the cylindrical outer shell; a feeding device is fixedly installed at the front end of the cylindrical outer shell through a pipeline, a material leaking hole is formed in the rear end ofthe cylindrical outer shell, a liquid collecting device is installed at the discharging end of the material leaking hole; and the rotating device is in tooth connection with a speed regulating modulethrough a coupler. According to the horizontal spiral discharging centrifuge, rotary centrifugal separation is carried out in the horizontal spiral discharging centrifuge through the centrifugal principle, so that solids can leak out by being tightly attached to the cylindrical outer shell, liquid flows out and is collected through the liquid collecting device, a large number of solid-liquid mixed materials can be continuously separated, and the working efficiency is greatly improved.
