連結管５を通って移動するうちに、相互に混合される。By Mr. Kawaguchi Figure 1 is a diagram illustrating the principle of the airtight liquid mixing device of the present invention. Containers 3 and 4, each having a piston 1.2, are connected via a connecting pipe 5, and a window 6 for measuring the concentration at the mouth of the pipe is provided.The concentration of the liquid in the pipe is measured by an absorption photometer (not shown). Since the pistons 1.2 synchronously reciprocate in opposite directions, the liquids i in the containers 3, 4 mix with each other as they move through the connecting pipe 5.

できる。The concentration of the mixed liquid can be measured using a densitometer. As shown in later examples, the absorbance (
y) is expressed by a damping curve in which the time t required to push the piston is taken as a constant and the number of reciprocations n of the piston is taken as a variable. Note that the shorter the time t for pushing the piston once, that is, the higher the flow rate, the shorter the time until the mixture reaches a predetermined concentration. Increasing the flow rate can be achieved by increasing the cross-sectional area of the pond or piston depending on the operating speed, or by reducing the flow diameter of the connecting pipe.

Two types of pistons with diameters of 3.2574 mm and 4.6066 mm were prepared. Piston 2 is a driving piston, and piston 1 is a floating piston. Each container 3.4 communicates with a replenishment liquid container 11 and a mixed liquid receiver 13 via an automatic valve 7, 8 and a connecting pipe 12.14, respectively.

。At this time, each connecting pipe 5.12 is also filled and discharged so that no gas remains in the container and the connecting pipe. When the piston 2 is driven, the piston l moves freely and the stock solution mixes with the stock solution a. The concentration of the mixed liquid is measured by an absorption photometer through the window 6, and if the predetermined concentration is not reached, the automatic valve 7 is opened, the piston 10 is driven, and the liquid is added to the stock liquid through the connecting pipe 12 from the replenishment liquid container 11. . Further, the piston 2 is driven to repeat mixing. In order to increase the mixing speed, the diameter may be reduced using the flow diameter adjustment device 9, but in this example, pistons with different cross-sectional areas were used to speed up the reciprocating motion of the pistons. Then, draw a graph in which the time t required for pushing the driving piston 2 is set as a constant j, the number of reciprocations of the piston is set as a variable, and the absorbance y is a function.
