Problems solved by technology

But such a thickener is expensive and costly
Secondly, the bottom of the thickener or the lower part of the side wall is severely worn due to the raking of the mud raking device. When the wear reaches a certain level, the thickener shell needs to be replaced or repaired, resulting in a significant increase in cost

Abstract

The invention discloses a thickener shell. The thickener shell comprises a tank body and anti-corrosion rubber lining layers, wherein the top of the tank body is open, and the bottom of the tank body is provided with a sand-holding hole; and the anti-corrosion rubber lining layers are arranged at the side wall of the inner circumference and the inner bottom wall of the tank body and the inner circumferential wall of the sand-holding hole. The thickener shell of the invention can be suitable for concentrated corrosive ore pulp and has low manufacturing cost.

Description

Technical field [0001] The invention relates to a thickener shell, in particular to a thickener shell suitable for thickening corrosive pulp. Background technique [0002] Thickener is a thickening equipment widely used in the fields of ore and metallurgy. The shell of the thickener is usually made of cement. However, shells made of cement are not suitable for large thickeners. For thickeners with larger dimensions, if the shell is poured with cement, the shell is likely to crack. To this end, it may be necessary to provide expansion joints on the housing and to seal the expansion joints. The sealing of expansion joints is very complicated, which increases the cost and is easy to leak, leading to safety hazards. In addition, the shell made of cement can only concentrate the non-corrosive slurry. [0003] For thickeners that concentrate corrosive pulp, the shell is usually made of pure metal, such as stainless steel or duplex steel. However, such thickeners are expensive and co...
