Claims

[Claims for Utility Model Registration] A device for continuously supplying a diluted solution of a predetermined concentration by mixing two or more different kinds of stock solutions to raw water, comprising: a circulation loop pipe for dilution; and the loop. A pump that forcibly circulates the mixed liquid in the pipe, two or more stock solution supply means for supplying two or more different kinds of stock solutions to the loop pipe, a raw water supply means that supplies raw water to the loop pipe, and a circulating diluent. a diluent discharge means for discharging the diluent, a means for adjusting the flow rate of the circulating fluid in the loop pipe, and a first lower chamber communicating with the stock solution supply means and communicating with the pump upstream side of the loop pipe through small paths, respectively. and a second lower chamber, a first upper chamber and a second upper chamber that communicate with the pump upstream side of the loop pipe, and a first upper chamber and a first upper chamber that communicate with the pump upstream side of the loop pipe.
The circulation loop includes a diaphragm disposed as a partition between the lower chamber and the second upper chamber and the second lower chamber, and an on-off valve fixed to the diaphragm to open and close each of the small paths individually. A liquid continuous dilution device comprising: a stock solution mixing amount adjusting means for adjusting the mixing amount of raw water and each stock solution according to pressure changes in a pipe;
