The present invention relates to a dissolution device, and more particularly, to a high-speed instantaneous mixing type liquid polymer dissolving device that can improve the dissolution rate after exposing the polymer to the liquid polymer by supplying and mixing the liquid polymer and water. it's about

In general, a polymer (polymer) has a large molecular size as a polymer and is not easily soluble in solvents such as water.

These polymers (polymers) are supplied in powder form and liquid form, and mainly powdered polymers are prepared as suspensions and used. There is a problem in that it is difficult to prepare a liquid.

In other words, the surface of the mass is gradually dissolved in contact with water, but the inside of the mass of polymer is blocked from water, so that the dissolution of the polymer by water proceeds very slowly, so it takes a lot of time to make a suspension of a desired concentration.

In order to solve this problem, Publication No. 10-201821 has been developed, and in this powder particle dissolving device, when the polymer supplied to the hopper is put into the feeder case, the transfer screw is rotated to supply it to the distribution header, and the injector through the distribution header The polymer dropped into the furnace is dried by the hot air supplied by the blower and the heater and is supplied to the inside of the injector at the same time, so that the dried polymer is supplied to the injector and the mixing unit connected thereto.

However, in this conventional polymer powder dissolving device, the polymer dropped from the distribution header, that is, the polymer just before being injected into the injector, is located on a straight line with the blower, so hot air is transmitted and dried, but the hopper, feeder case, screw, and cylinder around the screw Since hot air is not directly transmitted to the polymer located inside, there is almost no drying effect by hot air, and external moisture flows into these interiors and comes into contact with the polymer during opening and closing of the lid of the hopper and the solvent valve that opens and closes the inside of the cylinder. Therefore, the problem of polymer agglomeration and sticking still occurs.

Accordingly, there is an urgent need to develop a technology capable of easily dissolving the polymer in water as well as preventing the polymer from sticking.
