Multi-liquid proportioned mixing device

Abstract

The invention discloses a multi-liquid proportioned mixing device. The multi-liquid proportioned mixing device comprises a first liquid storage tank, a second liquid storage tank and a liquid storage vessel, wherein the first liquid storage tank is used for storing first liquid, the second liquid storage tank is used for storing second liquid, and the liquid storage vessel is in pipeline connection with the first liquid storage tank and the second liquid storage tank respectively; a first valve and a first flow meter are sequentially connected between the first liquid storage tank and the liquid storage vessel in a pipeline connection manner, and a second valve and a first metering pump are sequentially connected between the second liquid storage tank and the liquid storage vessel in the pipeline connection manner. The multi-liquid proportioned mixing device further comprises an automatic control device which is used for acquiring first flow signals of the first flow meter and controlling the first metering pump to quantitatively output the second liquid according to the first flow signals. According to the multi-liquid proportioned mixing device disclosed by the invention, flow meters and metering pumps are respectively mounted on a plurality of pipelines, and outputs of the metering pumps are controlled proportionally in a manner of acquiring data of the flow meters by the control device, so that the rapid dilution and proportioned mixing of a variety of liquids are realized, and the concentration of the mixed liquid is stable.

Description

[0001] technical field [0002] The invention relates to a multi-liquid proportional mixing device. Background technique [0003] On the existing beverage production line, the stock solution dilution and mixing device basically adopts a manual method, such as figure 1 As shown: open the replenishment valve 1, inject treated water 7 into the container 3, judge the amount of water added by the mirror device 4, add a certain amount of treated water 7, then add the original solution 8 to the container 3 through the original solution adding pump 2, Simultaneously start the circulating mixing pump 5 for circulating mixing, take out the diluted and mixed liquid through the sampling valve 6 to manually detect the diluted concentration, compare it with the required concentration, then add the treated water 7 or stock solution 8 to the container, until the required concentration is reached. This device needs to manually control the addition of the treated water 7 and the original so...

AI Technical Summary

Problems solved by technology

This device needs to manually control the addition of treated water 7 and stock solution 8, which is time-consuming and laborious, and is often adjusted according to manual experience, with low precision, and is not suitable for occasions where the stock solution 8 is consumed.
