  • Patent number: 11865500
    Abstract: Disclosed are an instant dissolving device by mass transfer and stretching with a cleaning structure and a dissolving method thereof. The dissolving device consists of a liquid inlet, a stretching repetition unit and a mass transfer unit, the stretching unit is sequentially composed of an upper fixed fluted disc, a movable fluted disc and a lower fixed fluted disc all with a plurality of through holes, and the upper fixed fluted disc and the lower fixed fluted disc are fixed to the dissolving device housing; the polymer gel solution is formed into a “uniform” solution after passing through the mass transfer unit. The dissolving device in the present invention is easy to install, and achieves instant dissolution of the polymers and improves the dissolution efficiency through the joint action of forced stretching and mass transfer by high gravity.
