7. The reaction kettle for preparing aluminum dihydrogen phosphate from foil process waste residues according to claim 6, wherein the feeding pipe (123) is made of transparent glass, and scale marks are arranged on the outer wall of the feeding pipe (123).
8. A process method for preparing aluminum dihydrogen phosphate from foil process waste residues comprises the following steps:
the method comprises the following steps: firstly, the waste residues are put into the net bag (8), and the same amount of waste residues are distributed in each part of the net bag (8) separated by the separation plate (14);
step two: fixing a sealing cover (11) on the top of the reaction kettle body (4) through a bolt;
step three: opening the heating wire (7), heating the inside of the reaction kettle body (4) through the heating wire (7), and keeping the temperature inside the reaction kettle body (4) within a certain threshold value through a temperature control system, wherein the heating time is controlled within 10-20 min;
step four: after a catalyst is put into the feed pipe (123) and a proper amount of the catalyst is measured, the sealing plate (122) is lifted upwards through the pull ring (126), so that the catalyst enters the reaction kettle body (4) through the feed port (121);
step five: simultaneously, the submersible pump (6) and the motor connected with the connecting rod (9) are started, so that the motor drives the stirring blade (15) to rotate through the engagement between the connecting rod (9) and each gear, thereby stirring the waste residue in the net bag (8), and effectively improving the catalytic efficiency of the catalyst for preparing aluminum dihydrogen phosphate from the waste residue.
