The invention discloses a filtering and impurity removing device of an aluminum oxide conveying system, and relates to the technical field of filtering and impurity removing equipment. The filtering and impurity removing device comprises a feeding barrel, a filtering chamber, a spiral feeding mechanism arranged in the feeding barrel and a comprehensive filtering mechanism arranged in the filtering chamber. The spiral feeding mechanism comprises a spiral rod, a rotating blade and a fixing seat, wherein the other end of the fixing seat is movably connected with the spiral rod, a rotating hole is formed in the center of the interior of the feeding barrel, the circumferential side face of the spiral rod is movably connected with the rotating hole, and the rotating blade is arranged on the circumferential side face of the spiral rod. The comprehensive filtering mechanism comprises a fine inclined filtering plate, a vertical plate and a transverse filtering plate, wherein the fine inclined filter plate is arranged on the internal side wall, close to the feeding barrel, of the filter chamber, the other end of the fine inclined filter plate is connected with the side wall of the vertical plate, the other end of the vertical plate is connected with the side wall of the transverse filter plate, and the other end of the transverse filter plate is connected with the internal side wall, away from the feeding barrel, of the filter chamber. According to the filtering and impurity removing device of the aluminum oxide conveying system, after impurity removal treatment, impurities are discharged into a storage groove through an impurity discharging groove, and the situation that a pipeline is blocked by large cakes is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of filter and impurity removal equipment, in particular to a filter and impurity removal device for an alumina conveying system. Background technique [0002] The aluminum electrolysis flue gas purification system adopts alumina dry purification technology to purify and recover the hydrogen fluoride gas in the aluminum electrolysis flue gas. The alumina raw material contains a large number of alumina agglomerates, and the particle size is about 5-15mm. Particles, fresh alumina will bring plastic cloth and other sundries during transportation, feeding and transportation. When fresh alumina mixed with sundries enters the feeding pipeline, it will cause the feeding pipeline to be blocked, resulting in uneven alumina raw materials. At the same time, due to the inclusion of material blocks, it will deposit in the air-driven chute feeding the electrolytic cell, resulting in poor air permeability of the chute boili...
