Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can take out liquids stored in a plurality of containers at a constant mixing ratio (weight ratio or volume ratio), and then stir-mix a plurality of liquids taken out. And a device for producing a mixed liquid.

[0002]

2. Description of the Related Art Conventionally, in the case of producing a mixture having a constant weight ratio or volume ratio of a plurality of liquids, the weight or volume of each liquid to be mixed is individually measured in a necessary amount and stirred.

[0003]

When applying, pouring, or filling a mixture, the required amount is measured and mixed. When the temperature changes, the density and viscosity of the liquid change. Further, the mixture cannot exhibit a predetermined performance unless it is mixed in an accurate mixing ratio. For this reason, it is a troublesome work that the weight and volume of each liquid must be individually measured and mixed.

In the present invention, the density and viscosity are kept constant by keeping the temperature of the liquid constant, and the pressure of the closed container is controlled by the pressurizing device. By doing so, the required amount of the liquid stored in the plurality of liquid storage containers can be simultaneously taken out at a constant ratio of the mixing ratio (weight ratio or volume ratio). The present apparatus can also have a function of applying, injecting, or filling a mixture prepared by mixing a plurality of taken out liquids. Therefore, it is possible to avoid the troublesome work of measuring the necessary amount and then mixing. In this way, the invention was made in order to meet the demand for improving work efficiency.

[0005]

To achieve the above object, A A container, a pressurizing device for pressurizing the internal pressure of the container, and a plurality of liquid storage containers are provided inside the container. Liquid storage container
The container may have a cut inside. As for the pressurizing device, in addition to the method of sending the gas compressed by the pump to the inside of the container, there is the method of sending the high-pressure gas of the gas cylinder to the container to increase the internal pressure. It can be carried out with or without a pressure reducing device to reduce the internal pressure of the container, but when configuring a device without a pressure reducing device, attach a cock near the discharge port of the pipe and store it. If it is not necessary to take out the liquid, the cock can be tightened to prevent the liquid from flowing out from the discharge port of the pipe tube. When the decompression device is attached, there is a method of depressurizing the gas inside the container with a pump, and a method of depressurizing the inside of the container using a solenoid valve. Also,
There is a method of controlling the internal pressure of the container by comparing the pressure inside the container electrically detected by a pressure sensor with a set value and adding a footback signal to the pressurizing device and the pressure reducing device. The pressurizing device and the depressurizing device may be inside or outside the container. The suction port of the pressure device is attached to the outside of the container, and the discharge port is attached to the inside of the container.
The suction port of the decompression device is attached inside the container, and the discharge port is attached outside the container. It is effective to install the B heater in a cylindrical shape so as to enclose the pipe tube. One end of a pipe tube equipped with a heater is put into the liquid of a liquid storage container, and the other end is taken out from the inside of the closed container to the outside. The caliber of the plurality of pipes is such that the amount of liquid discharged from the plurality of pipes becomes a flow rate proportional to the mixing ratio when the internal pressure of the container is increased. If the pipes with heaters have the same diameter, install a valve, a partition plate, or a pipe with a different diameter in the middle of the pipe so that the amount of liquid discharged from the pipe becomes Use a caliber that provides a proportional flow rate. In order to keep the C heater temperature at a constant temperature more accurately,
There is a temperature sensor for detecting and measuring the temperature of the heater, or a method of attaching a bimetal to control the voltage and current applied to the heater to control the temperature more accurately.

[0006] When the liquid suspension discharged from the D container is mixed to form a mixture, a plurality of liquids that have passed through the pipe tube are allowed to meet at the meeting portion, and then the liquids that have joined to the tube tube connected to the meeting portion are allowed to pass through. All of them are sent to the outlet of the tube. E The mixer mixes the liquid sent from the meeting part toward the outlet of the tube with mechanical force from outside of the tube to move up and down, left and right, front and back, or strike or vibrate. , The liquid in the tube is stirred and mixed uniformly and discharged. It is effective to combine these movements to give a mechanical vibration movement. The mixer is equipped with a transformer, a solenoid, or an electric motor to drive the tube so as to give an oscillating motion, and mechanically expands and contracts the tube to stir and mix. Further, when the ultrasonic transmitter is used as a mixer, the ultrasonic waves directly give an oscillating motion to the liquid inside the tube, so that the tube can be stirred and mixed without expanding and contracting.

[0007]

In the liquid supply device configured as described above, when the liquid is stored in the liquid storage container inside the A container, the internal pressure of the container is increased by the pressurizing device, and the liquid is stored in the liquid storage container. The liquid passes through the pipe tube equipped with the heater and tries to come out from the discharge port outside the container. The amount of liquid taken out of the container is controlled by the gas pressure inside the container. When the gas pressure inside the container is increased by the pressure device, the pressure is evenly applied to the liquid stored in the liquid storage container. At this time, if the pressure to be applied and the viscosity within a certain range in which the liquid easily flows are maintained, it is possible to always take out a certain amount of the liquid from the container. Therefore, the amount of liquid to be taken out can be increased by increasing the internal pressure of the container with the pressurizing device, and the amount of liquid to be taken out can be decreased by lowering the internal pressure of the container by using the depressurizing device. By increasing the temperature of the liquid and maintaining a certain temperature range, the B heater can maintain the viscosity at which it easily flows regardless of the outside air temperature of the container.

[0008] In order to mix a plurality of liquids discharged from the C pipe tube and mixed, the liquid is allowed to meet at the meeting part connected to the pipe tube. D The liquid mixture that has been made to associate at the association portion deforms or expands or contracts when a force is applied, and while passing through the inside of the tube, it expands or contracts vertically or horizontally or back and forth or hits or Vibration or mechanical movement that combines these movements is applied by a mixer to stir and mix the liquid.

[0013]

Since the present invention is constructed as described above, it has the following effects.

A required amount of a mixed solution having an accurate mixing ratio can be quickly taken out of the liquid storage container without using a weighing platform. Further, since there is no work to transfer the liquid to another container for stirring and mixing, the work time can be shortened and the work can be performed even in a narrow place.

A heater can be used to raise the temperature of the mixture. Therefore, the viscosity of the mixed liquid is lowered and the workability is improved. Further, when the mixed liquid is an adhesive such as urethane resin or epoxy resin, the reaction time increases when the temperature of the resin is raised, and the reaction time is shortened, so that the working time can be shortened.

The liquid can be discharged from the container by applying pressure. Therefore, it is possible to supply a device that can easily apply, inject, or fill the liquid even in the back of a narrow crack in which a spatula or a brush cannot be easily inserted.
