Problems solved by technology

[0007] However, in the existing equipment, when putting in 3H 2 SO4 and 6H 3 PO4, in order to ensure that 2Al(H 2 PO 4 ) 3 To be able to evenly adhere to the surface of the product, it is usually necessary to make 3H 2 SO4 and 6H 3 PO4 is put into the equipment in phases, but when feeding, manual feeding is usually used, the dosage is difficult to control, and the interval time for use cannot be guaranteed to be uniform, which will cause the catalyst to not be evenly sprinkled into the reaction container when feeding, thus affecting 2Al(H 2 PO 4 ) 3 production quality

Abstract

The invention discloses a catalyst circulating feeding structure for preparing aluminum dihydrogen phosphate from foil process waste residues, and relates to a feeding device; the catalyst circulatingfeeding structure specifically comprises a support ring and a feeding disc mounted in the support ring, a fixing frame is integrally formed and mounted on one side of the plane of the support ring, and a motor is fixedly mounted on the outer wall of the fixing frame through bolts; an output shaft of the motor is fixedly connected with one side of a feeding disc, a feeding port is formed in the top of the support ring, a discharging port is formed in the bottom of the support ring, and the two sides of the arc face of the support ring are fixedly connected with the top end of a vertically-installed supporting plate in a welded mode respectively. Through the design of the feeding disc, the cyclic feeding of the catalyst can be realized, so that the catalyst is circularly and uniformly fed in the preparation process of the aluminum dihydrogen phosphate, the reaction balance of the aluminum dihydrogen phosphate is improved, and the production quality of the aluminum dihydrogen phosphate is further improved.

Description

technical field [0001] The invention relates to a feeding device, in particular to a catalyst circulation feeding structure for preparing aluminum dihydrogen phosphate from waste residue in a foil process. Background technique [0002] Aluminum dihydrogen phosphate (Al(H 2 PO 4 ) 3 ) is a colorless, odorless, extremely viscous liquid or white powder, easily soluble in water. It is often used as a binder for refractory materials. It is mainly used in electrical, high-temperature kilns, heat treatment resistance furnaces and electrical insulation. It is also used in petroleum, chemical, shipbuilding and space technology. It can also be used in combination with inorganic coatings and organic coatings. . At present, the production of aluminum dihydrogen phosphate is mostly limited to the reaction of aluminum hydroxide or aluminum oxide with phosphoric acid. [0003] At present, the surface polishing of aluminum alloys at home and abroad generally adopts three technologies: ...
