JPH08974Y2 - Liquid mixing device - Google Patents

Description

TECHNICAL FIELD The present invention relates to a device for rapidly and efficiently mixing a plurality of types of liquids.

Conventional technology In order to mix multiple types of liquids, it is common to supply these liquids to a tank-shaped mixing tank and forcibly mix them through a stirring blade. When a vortex is generated, air is entrained in the vortex and air is mixed in the mixed liquid, which makes it inconvenient to mix air, for example, when handling materials that may promote oxidation during mixing. Is not preferable.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention has been made for the purpose of providing a liquid mixing apparatus that overcomes the drawbacks of the conventional liquid mixing apparatus and provides a required liquid mixture without mixing air. It is a thing.

Means for Solving the Problems The present inventor has conducted various studies to develop a liquid mixing apparatus having the above-mentioned preferable characteristics, and as a result, sucked a plurality of liquids to be mixed into a cylinder through a piston. The inventors have found that the objective can be achieved by injecting the internal liquid through the piston after flowing it in, and have completed the present invention based on this finding.

That is, according to the present invention, at the other end of the cylinder 1 into which the piston 2 is fitted from one end, a jet pipe 9 located substantially at the center and a plurality of suction pipes 10 ... Provided is a liquid mixing device in which a check valve 12 and a control valve 13 are respectively provided in an on-off valve 11, a suction pipe 10 ...

Embodiment An embodiment of the present invention will be described with reference to the drawings. As an example, the drawing relates to mixing soymilk, which is a raw material in the production of tofu, and nigar (a magnesium chloride aqueous solution) which is a coagulant. Reference numeral 2 is a piston, 3 is an air cylinder that reciprocates the piston, and 4 is a base. In the illustrated embodiment, the base 4 is attached to a wall surface of a building and is vertically operated.

The piston 2 is formed in a shape such that the tip thereof matches the inner surface of the other end (lower end) of the cylinder 1, and the piston rod 5 connected to the piston 2 is connected to the air cylinder 3 via a universal joint. In addition, 6 is a piston ring and 7 is a ₀ ring.

The cylinder 1 is sandwiched and fixed to a split member 8 provided on the base 4, so that the cylinder 1 can be freely attached and detached and the mounting height can be adjusted. At the other end (lower end) of the cylinder 1, there are a plurality of (two in the figure) suction pipes 10 and 10 which are located at the center of the hollow pipe and surround the jet pipe 9 near the periphery.
Are provided so as to communicate with the inside, respectively. Further, an on-off valve 11 is provided at the ejection pipe 9, and a check valve 12 and a control valve 13 for adjusting the flow rate are provided at the suction pipes 10 and 10, respectively. There is. The suction pipes 10 and 10 are connected to the soy milk tank 14 and the bittern tank 15 via hoses, and a receiver 16 is arranged immediately below the ejection pipe 9.

Action and effect of the invention To use the device of the invention, the opening / closing valve 11 is closed while the piston 2 is lowered to the lower end of the cylinder 1 via the air cylinder 3, and the flow paths of the soy milk tank 14 and the bittern tank 15 are provided. Is opened to fill each suction pipe 10 with both liquids, and then the piston 2 is pulled up through the air cylinder 3 as shown in the drawing. Then, the liquid in the soy milk tank 14 and the bittern tank 15 is sucked into the cylinder 1 through the control valve 13 adjusted to each predetermined amount and the check valve 12 which opens only in the inflow direction and is filled in the cylinder 1.

Subsequently, when the on-off valve 11 is opened and 1 is lowered via the air cylinder 3, these filled liquids are received from the ejection pipe 9 to the receiver.
Enter 16 to get the required mixture. In this case, the suction tube
From 10 and 10, liquid does not flow out due to the action of the check valves 12 and 12.

As described above, according to the present invention, a plurality of liquids to be mixed are sucked through the control valves 13 and 13 in the respective required amounts, and the cylinder 1
After the liquids are mixed with each other through a rapid flow input by a vacuum force, the required liquid mixture is obtained from the ejection pipe 9 while further mixing is performed by increasing the liquid pressure due to the pressure reduction of the piston 2. However, the operating principle thereof is, like the water gun of a toy, for example, the injection in a state where it is not intervened by air, so that mixing can be performed efficiently and extremely quickly in accordance with the above-mentioned purpose.

In the illustrated embodiment, the whole is used as a vertical type, but it may be a horizontal type or a horizontal type, and the reciprocating movement of the piston is an electric type using a rack mechanism or the like instead of the air cylinder. May be.
