JPH09227838A - Apparatus for continuously forming stock paste by dissolution - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an apparatus by which a paste material such as a dyeing paste can be dissolved without deteriorating the paste as a result of the cleavage of molecules of the paste by the impellers and without forming any agglomerates of an unwetted powder even when the concentration of the solution is as high as 10-20%. SOLUTION: A specified amount of a powder material 1 being the starting material for a stock paste is discharged from a holding hopper 2, dusted with air blown from a blower 6 through a pressure feeder 5 and fed into a dissolution vessel 8. At the same time, water having a pressure which is always kept constant by a pressure regulation valve 11 is injected into the vessel at a controlled flow rate and sprayed over the dusted material 1 in the vessel 8 to dissolve the material 1 instantly without fail, and the obtained stock paste is transferred to a holding tank.

2. Description of the Related Art Conventionally, paste liquid dyes used for dyeing various kinds of fabrics are those in which a dye and a high-viscosity original paste are blended. In order to obtain the original paste, the original paste raw material is used. It dissolves a certain starchy or chemical powder with fresh water. To dissolve this powder, pour powder and fresh water into an appropriate amount in a tank of appropriate size with a stirring blade inside. However, the solution is agitated by a stirring blade to dissolve it until it reaches a high-viscosity original paste. However, during the storage period of the powder, fine particles of the powder often absorb moisture and partly solidify into granules, or when stirring with fresh water, some of the powder does not dissolve in fresh water and is sprinkled ( It becomes a mamako-like mass and it is not possible to easily obtain a uniform base paste. In addition, in order to save time and effort in stirring in this stirring tank, a large amount of powder is poured at a time together with the injection of fresh water, and even if the mixture is stirred for a long time, it is easily made uniform and a high-viscosity original paste is obtained. There is no such thing.

Recently, a certain amount of powder is cut out and air is blown into the powder to make it into a stirring tank. At the same time, fresh water is injected and the stirring blades are used for time. In some cases, the mixture is stirred and stirred so that it does not form the above-mentioned powdered (Mamako) -like mass, but in this case, the relationship between the amount of powder and the amount of fresh water input is powder <fresh water, After pouring the body, fresh water is injected to a predetermined concentration to make it uniform with a stirring blade. The dissolved concentration of these powders is 2% or less, and a small amount of powder is poured into a large amount of water. Although it is possible to easily dissolve it, on the other hand, since the glue molecules are sheared by the stirring blades and the properties as the original paste are deteriorated, the method of dissolving the powder without stirring and improving the properties of the powder Even if a large amount of powder is added, the dissolved concentration of the body is 10 to 20%. Method for producing a source glue made in which is desired.

[0004]

SUMMARY OF THE INVENTION The present invention was created in view of the present situation, and the problem to be solved is to dissolve a glue material such as a dye paste by stirring a glue molecule by stirring with a stirring blade. Dissolves without causing shearing and deterioration, and even if the dissolution concentration is increased to 10 to 20%, it is possible to dissolve uniformly so that it does not form a lump like powder (Mamako). .

According to the present invention, the powder is quantitatively cut out by a known cutting means such as a screw feeder from a lower end of a hopper for storing the powder material which is a raw material of the original paste, and the powder is fed to a pressure feeder. Along with the transfer, the powder is made into dust by the air blown from the blower from the other side of the pressure feeder and fed into the continuous melter, and further from the side upper end of the melter, a flow meter, a pressure switch, Water pipes through the pressure control valve and solenoid valve are laid to keep the water pressure constant and the flow rate is controlled to inject water, and the powder material dusted in this dissolver is sprayed with water at a predetermined water pressure. The powder material is instantaneously and surely melted and transferred to the storage tank for the original paste.

[0006]

According to the present invention, when the powder is quantitatively cut from a lower end of a hopper for storing the powder material by a known cutting means such as a screw feeder, the number of revolutions of the powder is controlled to control the powder. The amount of powder to be delivered per unit time of the body is calculated, and this is made into dust by the air blown out by the blower and sent into the continuous melter, and to the water pipe that is piped to the side of the melter. Is to measure the amount of water supply through a flow meter, pressure switch, pressure control valve and solenoid valve, and to adjust the water injection pressure and to measure the amount of water supply per unit time for the amount of powder added. is there. Furthermore, the powder that was dusted from the pressure feeder was introduced from above the center of the dissolver, and the water introduced from the water pipe at the upper end of the side was made into an elliptical shape on the lower peripheral surface of the partition plate. The vertical cross section has an appropriate number of reverse conical ejection holes, and the reverse V-shaped spray groove is cut from the lower surface toward the center of the ejection holes, and the water introduced into this is the entire peripheral surface of the dissolver. The powder material is instantly sprayed by forcing the powder and spray water to come into contact with each other in the middle of the dissolver. Therefore, it is intended to surely promote the dissolution and achieve the above-mentioned problems.
