The utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that existing apparatus exists, and provide a kind of metering chemicals dosing plant, it not only can provide difference more than two is added the requirement that snack made with traditional Chinese medicines adds dissimilar medicaments simultaneously, simultaneously, the medicament that can also be respectively difference be added snack made with traditional Chinese medicines measures accurately.
The purpose of this utility model is realized by following technical scheme:
A kind of metering chemicals dosing plant, be provided with medicine storing pot, it is characterized in that: be in series with control valve on the pipeline of the port of export of several medicine storing pots respectively, the output of control valve is parallel with several pipelines, every pipeline is when linking with measuring pump respectively, and will link to each other between several medicine storing pots, the arrival end of each measuring pump respectively is equipped with a flow Calibration Column, on each measuring pump output pipe flap valve is installed.
Described measuring pump is single head or multihead metering pump.
Described control valve is ball valve or control valve.
Series connection one strainer on the pipeline of the described medicine storing pot port of export.
The Safety control valve of respectively connecting on the pipeline between described medicine storing pot and the measuring pump output.
On the pipeline of described measuring pump arrival end control valve is installed.
The beneficial effects of the utility model: the utility model can provide unit and differently more than two add the requirement that snack made with traditional Chinese medicines adds different medicaments, and simultaneously, the medicament that can also be respectively difference be added snack made with traditional Chinese medicines measures accurately.The utility model is applicable to that floor space is little, the individual well dosing under the operating modes such as the platform of compact conformation, man-made island or artificial well site or the dosing of gathering system.
