Storage equipment used in alumina industry

Abstract

The invention relates to the field of alumina production, in particular to slurry storage equipment used in the alumina industry, solves the problems that the baseplate of conventional storage equipment is susceptible to abrasion and the impeller of a discharging pump is susceptible to damage, and can prolong the service life of the storage equipment which is simple in structure and protect associated equipment. According to the storage equipment, guide skewed slots tilting down are formed in a tank body; the higher ends of the guide skewed slots are connected with a feed opening; the lower parts of the lower end outlets of the guide skewed slots correspond to anti-impact cones; the anti-impact cones are arranged at the bottom in the tank body and fixed on the baseplate of the tank body; slurry down from the guide skewed slots can flow onto the anti-impact cones, so that the slurry are prevented form impacting the baseplate of the tank body when flowing down. The discharge openings I of the storage equipment are formed in the bottom of the tank body and are higher than an emptying opening; meanwhile, screen stencils are arranged at the discharge openings II of the inner wall of the tank body. Thus, the steel balls, which become smaller due to abrasion, cannot flow out along with the slurry through the discharge openings I, so that the safe use of the discharging pump is ensured.

Description

technical field [0001] The invention relates to the field of alumina production, in particular to a slurry storage device used in the alumina industry. Background technique [0002] In the production of alumina, the slurry ground by the ball mill contains a large amount of silt and impurities. When the slurry enters the storage equipment, it will produce impact and wear the bottom plate of the storage equipment, thereby affecting the service life of the storage equipment. [0003] In addition, the steel balls in the ball mill will become smaller after a long time of use. When they are small enough, the steel balls will easily flow into the storage tank with the slurry, and when they flow through the discharge pump through the discharge port, they will Damage the impeller of the discharge pump, and eventually damage the blades of the pump. Therefore, a storage device with a new structure is needed to solve the above problems. Contents of the invention [0004] The purpos...
