Device and method for purifying selamectin

Abstract

The invention discloses a device and method for purifying selamectin, and relates to the technical field of selamectin purification, and the key point of the technical scheme is that the device comprises a fixed frame; the collecting box is fixed to the fixing frame, one side of the collecting box is fixedly connected with a fixing ring, and the interior of the fixing ring is rotationally connected with a tank body used for storing raw materials; the sampling device comprises a fixed frame, a driving mechanism, the driving mechanism is arranged on the fixed frame, the driving mechanism comprises a motor, the motor is arranged on the fixed frame, an output shaft of the motor is fixedly connected with an electric telescopic rod, and the bottom end of the electric telescopic rod is fixedly connected with a cover plate. The raw materials in the tank body are stirred, and after stirring is finished, the raw materials at different positions in the tank body are extracted by pressing the sampling devices at different positions, so that the stirring condition of the raw materials is known, and the situation that the raw materials are insufficiently stirred and purification of the raw materials is affected is avoided.

Description

Technical field [0001] The present invention relates to the field of purification techniques of serraminin, more particularly, it relates to a purification apparatus and method of serraminin. Background [0002] Serraminin (also known as sirambin) is formed by fermentation of a new strain of Strepterobacterium arverobacterium that has been genetically recombined. [0003] On the one hand, the mechanism of action of serramin can act as an agonist of γ-aminobutyric acid (GABA) to trigger the release of presynaptic GABA, which in turn causes membrane to Cl - Increased permeability, on the other hand the drug can make glutamate-controlled chloride channels open, so that Cl - Increased permeability leads to hyperpolarization of membrane potentials, thereby blocking the conduction of nerve signals and causing rapid, lethal, and non-Chemicalbook spastic neuromuscular paralysis to die. Because trematosomiasis and tapeworm do not have GABA neurotransmitters and glutamate-controlled Cl - c...

AI Technical Summary

Problems solved by technology

[0004] In the related technology, methanol is put into the raw material of selamectin for dissolving and stirring, followed by recrystallization operation, and then purified selamectin is obtained. During the stirring process, when the amount of raw material input is large, there may be accumulation of raw material, Unable to fully dissolve, resulting in different concentrations of raw materials distributed in different positions in the tank, which in turn affects the purification of selamectin
