Above-mentioned overflow circle is welded on the cylindrical shell, and for horn-like, hydraucone is positioned at material feeding box.
Above-mentioned spiral plate is continuous layout in the intravital stripping section of tube, is to be interrupted to arrange at segregation section; It highly is 1/4 of a barrel diameter, and spiral plate has simple helix, three forms such as spiral. the balance port of balance dissolution fluid is arranged at the spiral plate bottom; Be welded with 6～12 material delivering plates between spiral plate, grog is promoted to move up by spiral plate, and material delivering plate has the effect that mixes grog.
Above-mentioned hopper has inclining bucket to extend into and carry in the materials device.
Be welded with symmetric 6 in the above-mentioned shell ring of carrying materials device and carry flitch, the residue after the grog stripping is put into hopper by carrying after flitch is mentioned, and discharges by hopper again.
The principle of work of quick stripping of flyash grog and isolating tubular digester is: the grog particle is through behind the crushing and screening, send in the cylindrical shell by material feeding box, cylindrical shell rotates under the driving of power system, grog is under the effect of spiral plate, move up by material feeding box one end, contact with the dissolution fluid that adds from hopper, generate sodium aluminate solution, flow out by liquid outlet by reaction; Remaining residue that can not stripping is then by carrying the materials device remover apparatus.
Quick stripping of flyash grog of the present utility model and isolating tubular digester have the following advantages: it realized with low-grade flyash be in the raw material production alumina process quick stripping with separate, this is because grog is to contact and stripping in relative flowing with dissolution fluid with block or spherical material form, therefore grog stripping and separation fast, realize liquid-solid sharp separation, also solved the serious problem of grog secondary reaction in stripping simultaneously.
