Example Embodiment

[0027] Such as figure 1 As shown, the present invention relates to an octagonal central drive shaft sleeve. The octagonal central drive shaft sleeve is formed by connecting a plurality of sleeve units up and down in turn. The structure of the sleeve unit is a regular octagonal cylinder 1 with top The top surface and the bottom surface are respectively provided with a top surface flange plate 2 and a bottom surface flange plate 3, and a supporting truss seat 4 is provided on both sides of the middle and upper part.

[0028] The present invention discloses a manufacturing process for manufacturing the above-mentioned octagonal center drive bushing. First, a regular octagonal cylinder body 1 is fabricated by flat welding, and then the top flange plate 2 is spliced ​​into one body, and then it is connected with the upper flange plate after leveling. The bottom flange plate 3 corresponding to a regular octagonal cylinder 1 is drilled in pairs and welded in pairs; the middle support tru...

Abstract

The invention relates to a technology for manufacturing an octagonal center driving shaft sleeve of a thickener. The technology comprises the following steps of manufacturing a regular octagonal barrel body in a flat welding manner; firstly splicing a top surface flange plate and the regular octagonal barrel body integrally; flattening the top surface flange plate, pairwise boring a bottom surface flange plate corresponding to an upper barrel body, and welding pairwise; firstly making a middle supporting truss into a component, and then assembling and welding according to a theoretical size; pairwise assembling the bottom surface flange bottom separately in the process of positively manufacturing and pre-assembling the upper barrel body and a lower barrel body, and welding pairwise. The technology for manufacturing the octagonal center driving shaft sleeve of the thickener has the advantages that the traditional high elevation welding is replaced by flat welding, the welding difficulty is reduced, the welding quality is improved, the overhead operation is greatly reduced, the operation safety coefficient is improved, and the working efficiency is guaranteed.

Description

technical field [0001] The invention belongs to the field of mining metallurgical equipment, and relates to a thickener, in particular to a manufacturing process of an octagonal central drive bush of the thickener. Background technique [0002] The thickener is a solid-liquid separation device based on gravity settlement, usually a cylindrical shallow tank with a conical bottom built from concrete, wood or metal welded plates as structural materials. [0003] The thickener is composed of a thickening pool, rake frame, transmission device, rake frame lifting device, feeding device, unloading device, etc. The rake frame is driven by a central drive shaft through the transmission device, and a central drive shaft is arranged outside the central drive shaft. set, such as figure 1 As shown, the hub of the central drive shaft is formed by connecting several hub units up and down in sequence. The hub unit structure is a regular octagonal cylinder 1, and the top and bottom surfaces...
