Large-scale seed precipitation tank body mounting construction method

Abstract

The invention relates to a seed precipitation tank construction method in an aluminum industry, and particularly relates to a large-scale seed precipitation tank body mounting construction method comprising the following steps: A, a tank bottom plate is mounted by a traditional method; B, hydraulic lifting pillars are uniformly arranged at a same circumference of the interior of a tank body, a mast is vertically arranged at the center of the interior of the tank body, and the top of the mast is connected with each of the hydraulic lifting pillars by a steel wire rope or a steel bar; C, a topmost ring of cylinder section and a tank top structure are assembled and welded on the periphery of the hydraulic lifting pillars, and the inner wall of the cylinder section is welded with a lifting-up bearing plate connected with the hydraulic pillars; D, the welded cylinder section is synchronously lifted up, a next section of cylinder section is welded, and the cylinder sections are assembled; E, the step D is repeated until welding of the whole cylinder sections is completed; and F, the lowest-part cylinder section and a bottom plate are connected and aligned, the auxiliary devices are dismounted, and the construction is completed. The construction method adopting the technical scheme of the invention has small requirements on a field, and is low in operation difficulty and high in construction efficiency.

Description

technical field [0001] The invention relates to a method for constructing a seed separation tank in the aluminum industry, in particular to a construction method for installing a large seed separation tank body. Background technique [0002] Due to the adjustment of the national industrial policy, the restriction and elimination of high-energy consumption and high-pollution industries have been continuously increased. Domestic alumina companies continue to adopt new technologies, new processes, new equipment and new materials, and move towards energy-saving, high-efficiency, large-scale and environmental protection. develop. Alumina production usually adopts a wet process, in which seed crystal decomposition is one of the key processes of the wet process.

Alumina production usually adopts a wet process, in which seed crystal decomposition is one of the key processes of the wet process. The main equipment for seed crystal decomposition is the seed splitting tank, which is a large metal cylinder. How difficult it is, due to the high equipment, there are a lot of high-altitude operations in the process of assembling and welding the side wall panels and roof panels, which not only requires high requirements for the site and operating equipment, but also makes the work difficult and inefficient for workers
