The utility model relates to the field of medicament proportioning, and discloses a medicament quantitative proportioning device, which comprises a fixed plate and a
mixing tank, the top end of the fixed plate is fixedly connected with the
mixing tank, the two sides of the top end of the
mixing tank are respectively provided with an inlet, and the two sides above the mixing tank are respectively provided with a class I medicament
storage tank and a class II medicament
storage tank. Metering valves are respectively arranged between the mixing tank and the I-type medicament
storage tank and between the mixing tank and the II-type medicament storage tank. According to the
drug quantitative proportioning device, the
first class I
drug original tank, the class I
drug transfer pump and the class II
drug transfer pump are all electric pumps, so that during
continuous feeding, even if drugs in one group of original tanks are used up, the other group of original tanks can be used for continuously pumping the drugs, the device operation is not influenced, the conditions of shutdown and waiting cannot occur in the production process, and the production efficiency is improved. And the metering valve can accurately control the volume of the medicament fed into the mixing tank each time according to a set proportion, so that accurate proportioning is realized, and the problems of poor proportioning efficiency and poor continuity are solved.
