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. The thickener comprises a shell, a drag line positioned in the shell and a drive device which drives the drag line to rotate, wherein the shell comprises a tank body and anti-corrosion rubber lining layers; 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 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, in particular to a thickener suitable for thickening corrosive pulp. Background technique [0002] Thickener is a thickening equipment widely used in ore and metallurgy fields. The casing of the thickener is usually made of cement. However, the casing made of cement is not suitable for large thickeners, and for larger thickeners, if the casing is poured with cement, the casing is easy to crack. For this it may be necessary to provide expansion joints on the housing and to seal the expansion joints. Expansion joints are complex to seal, which adds cost, and are prone to leaks, causing safety hazards. In addition, the shell made of cement can only concentrate non-corrosive slurry. [0003] For thickeners that thicken corrosive pulp, the shell is usually made of pure metal, such as stainless steel or duplex steel. But such thickeners are expensive and costly. Secondly, the bottom of the thickener or the lower pa...
