Pneumatic medicine dissolving device and medicine dissolving method

Abstract

The invention discloses a pneumatic medicine dissolving device and a medicine dissolving method, and solves the problems in the prior art that stirring equipment is easily corroded when the stirring equipment is in direct contact with a medicine, the service life is shortened, and a metering pump at the rear end is blocked by the impurity stacked at the inner bottom part of a medicine dissolving tank. The pneumatic medicine dissolving device comprises the medicine dissolving tank, an annular gas pipe, an air intake tube, a gas ejector pipe, a fluid reflector, a guide cylinder, a reflection plate, a medicine discharge pipe, a medicine liquid discharge valve, an air intake regulation valve, a universal joint and a sprayer. The medicine dissolving method comprises the following steps: step 1,checking the performances of the pneumatic medicine dissolving device; step 2, adding a solvent and the medicine into the medicine dissolving tank; step 3, starting the air intake regulation valve toinflate air into the medicine dissolving tank; step 4, starting the medicine liquid discharge valve to convey a medicine liquid out; step 5, starting a blowoff valve to drain the residual medicine; and step 6, repeating the steps 1-5 to circularly dissolve the medicine. The pneumatic mode is used to stir the medicine liquid in the medicine dissolving tank, the stirring equipment is effectively prevented from being corroded by the medicine liquid, the metering pump at the rear end is effectively prevented from being blocked by the impurity in the medicine liquid, and the stirring efficiency ishigh.

Description

technical field [0001] The invention relates to a pneumatic drug dissolving device and a drug dissolving method. Background technique [0002] Existing products are usually in the form of mechanical blade stirring, using a combination of motor + reducer + stirring rod and blade. During the operation, the mechanical noise is large, and mechanical failures occur from time to time. The stirring rod and leaves are in contact with the medicine, and the corrosion is relatively serious. Often in practical engineering applications, industrial-grade drugs contain many solid impurities that cannot be dissolved, and the way of blade stirring usually forms impurities accumulation at the bottom of the dissolver, and impurities enter the back-end metering pump and cause the metering pump to block. Ultimately affect the stability of the entire system operation, resulting in economic losses. Contents of the invention [0003] The technical problem to be solved by the present invention ...
