The invention discloses a method for obtaining a sorted and purified autoimmune vaccine, which comprises the following steps: S1, extracting 30ml of autologous blood sample of a patient, and sorting to obtain CD34 + cells; s2, carrying out flow analysis on the CD34 + cells to ensure that CD34 + is greater than or equal to 90%, counting by using a counting instrument, and adjusting the concentration of the CD34 + cells to be 1 * 106 / mL; s3, the extracted cells are placed in a 42 DEG C constant-temperature water bath kettle for heat shock treatment, and the heat shock treatment lasts for two hours; s4, collecting the cells obtained in the step S3, transferring the cells into liquid nitrogen at-196 DEG C and a water bath kettle at 37 DEG C, and repeatedly freezing and thawing for multiple times; s5, collecting after detecting that no living cells exist by using a cell counter, and centrifuging for 10 minutes at the rotating speed of 6000 r / min under the centrifugal condition of 4 DEG C; s6, after the centrifugation is finished, discarding the supernatant and leaving the precipitate, and resuspending by using normal saline; and S7, irradiating 200 GY through gamma rays for 60 minutes, collecting the sample, sending the sample, and inspecting the sample for later use after the sample is qualified.

The utility model relates to the technical field of fermentation tanks, and discloses a seaweed fertilizer fermentation and decay tank which comprises a tank body, a sealing cover is arranged at the top of the tank body, a shaking mechanism for driving seaweed to move up and down and a turning mechanism for turning the seaweed are arranged on the tank body, the shaking mechanism comprises a motor, and the motor is connected with the sealing cover. The motor is fixed at the bottom of the tank body; a reciprocating screw rod is fixed at the output end of the motor; the screen frame is in threaded connection with the outer wall of the reciprocating lead screw; and the guide rod is fixed on the inner wall of the tank body. According to the seaweed fertilizer fermentation corruption tank, when fermentation operation needs to be carried out and a motor is started, a screen frame can be driven to move up and down on a reciprocating lead screw, seaweed in the screen frame can be driven to move up and down in a reciprocating mode, the seaweed in the screen frame can also move up and down in liquid in the tank body, and then the seaweed can be loosened in the tank body; and the seaweed can be fermented more uniformly.

The utility model discloses a drying device for electrostatic spraying, and relates to the technical field of electrostatic spraying. The electrostatic spraying device comprises a spraying part, wherein the spraying part is used for carrying out electrostatic spraying on materials; the drying part is mounted on the left side of the spraying part, and the drying part is used for drying the sprayed material; wherein the spraying part comprises an electrostatic spraying box, and a suspension type conveying chain main body is mounted in the electrostatic spraying box. The adjusting assembly is arranged, specifically, the air outlet base blows out hot air, in the drying process, the electric push rod is started to stretch out and draw back in a reciprocating mode, at the moment, the output end of the electric push rod drives the rack to do reciprocating motion through the fixing block, the rack drives the guide blade to rotate through the convex teeth, and at the moment, the guide blade rotates on the rotating shaft; the blowing-out direction of hot air can be adjusted, the hot air is blown out in a swinging mode, the drying effect is improved, and the working efficiency is improved.
