Problems solved by technology

[0004] Different combinations of materials, differences in material thermal expansion, and the conical bottom structure is constrained by the cylinder wall. The restricted thermal expansion of materials may easily cause the acid-resistant bricks at the bottom to be dislocated, loose, cracked, and fall off. Mechanical failure and pipe blockage

Abstract

The present invention discloses a thickener including a pool body, the pool body has a cone part, a plurality of first anticorrosive brick structures are arranged on the inner surface of the cone part, the first anticorrosive brick structures are arranged round-by-round from top to bottom, both sides of the first anticorrosive brick structure are provided with a contraction joint along the radial direction. The contraction joint is arranged on the first anticorrosive brick structure along the radial direction, the temperature change adaptive capacity of the first anticorrosive brick structure is improved, the combination strength of the first anticorrosive brick structure and the inner surface of the cone part is enhanced, and corrosion resistance and operational stability of the thickener can be ensured.

Description

technical field [0001] The invention belongs to the technical field of hydrometallurgy, and in particular relates to a thickener. Background technique [0002] Thickeners used in hydrometallurgical technology often need to consider the issue of anti-corrosion. No matter whether the pool body is made of steel or concrete, the inner wall and bottom contacting the process medium often need to be lined with glass fiber reinforced plastic isolation layer and acid-resistant bricks, or lining Composite lining structure of acid-resistant rubber and acid-resistant bricks. [0003] The cone bottom of the thickener needs to be considered to have a certain inclination angle in order to facilitate the discharge of the underflow. The laying of acid-resistant bricks at the cone bottom of the traditional thickener is in a parallel arrangement structure, and the bricks are connected by cement. [0004] Different combinations of materials, differences in material thermal expansion, and the c...
