  • 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.

  • Publication number: 20200300054
    Abstract: A method for preparing an artificial core includes steps of: (1) preparing materials: dividing quartz sand of different particle sizes into multiple groups, adding a cementing agent into all the groups, and thoroughly stirring to obtain quartz sand mixtures with different permeabilities; (2) assembling a mold: assembling the mold into a cuboid with a hollow sand-filling groove inside; (3) wetting the mold: spraying water onto a bottom surface of the sand-filling groove with a fine water nozzle to wet the mold; (4) filling with sand: placing separators in the mold to divide the sand-filling groove into multiple parts corresponding to a group quantity of the quartz sand; sequentially pouring the quartz sand mixtures into the mold in an order from large to small particle sizes; then removing the separators, and flattening a surface of the quartz sand mixtures; (5) compacting; and (6) firing for molding and de-moulding.
