DESCRIPTION:
BRIEF SUMMARY
BACKGROUND AND SUMMARY OF THE INVENTION
1. Technical Field
The present invention relates to a dissolving device for automatically preparing solutions of dyes for use in various dyeing experiments.
2. Background Art
Operations for dissolution (dissolution means in this invention both dissolution of water-soluble dyes and dispersion of water-insoluble dyes such as disperse dyes) of dyes and the like have been carried out by a manual operation performed by workers using a balance, a messflask, a dissolving vessel, an agitating device, etc. which includes operations for accurate sampling of dyes or the like, accurate charging of media (media mean in this invention water, as well as organic solvents containing water), an agitating operation for dissolving them and other such operations which require much time and skill in order to obtain the required accuracy. And further, the thus obtained dye solutions tend to cause precipitation, coagulation, etc. till they are utilized for actual dyeings and, particularly, when it is required to prepare a number of dye solutions, operations from the dissolving work of dyes to the actual dyeing operation inevitably become complicate.
Accordingly, there has been a need for a dissolving device that does not require much time and skill and can provide an accurate sampling amount, as well as can obtain a stable solutions of dyes and the like in which the obtained solutions do not coagulate or the like.
Disclosure of Invention
The present inventors have continued an earnest study for solving the foregoing problems which have led to the developments of the present invention.
Thus, the present invention relates to an automatic dissolving device for dyes comprising:
(1) an electromagnetic valve situated midway in a pipeline from a medium or stock solution tank to a dissolving or mixing vessel,
(2) a turntable with a number of holes disposed around the circumference thereof to accept a number of dissolving or mixing vessels,
(3) an electronic type balance disposed below the turntable to weigh the dissolving or mixing vessels, and one or more magnet-type stirring devices arranged below the turntable for stirring the solutions in the dissolving or mixing vessels, and
(4) a mathematical operation control device.
It is possible by using such a device to prepare stable solutions of dyes or the like automatically and successively while shortening the working time, requiring no operator's skill, at an accurate weighed amount and causing no changes such as precipitation or coagulation during storage until actual dyeings. The application of the automatic dissolving device according to the present invention is not restricted to dissolutions of dyes but is also applicable to the preparation of solutions consisting of dyes and dyeing auxiliaries such as sodium sulfate and soda ash, or to the preparations of solutions consisting only of dyeing auxiliaries.
In the present invention, the tare of the dissolving vessel (receiver vessel) situated in the holes of the turntable are at first measured by the electronic type balance disposed below the turntable and then an eye-measured dye is charged thereto and the weight of the vessel containing the dye is again measured, whereby the amount of the weighed dye is exactly calculated by the mathematical operation control device interlocking with the electronic type balance. Then, after rotating the turntable to another position and adding a medium controlled to a predetermined amount by the mathematical operation control device by opening the electromagnetic valve situated midway in a pipeline from a medium tank to the receiving (dissolving) vessel, the dye is dissolved by the stirring conducted by a number of magnet-type stirring devices also arranged below the turntable. Thereafter, the solution containing the dye is stirred by another magnet-type stirring device arranged below the turntable in order to keep the solution stable. By repeating the above-mentioned procedures using a number of receiving vessels while successively turning the turntable, so
