Large-scale mining bolted-connection cylinder body adopting steel structure

Abstract

A large-scale mining bolted-connection cylinder body adopting a steel structure is applied to stirring and mixing industries, and comprises a wall board, a base plate, a pre-buried plate, an ore feeding opening, an ore discharging opening, filler and bolts, wherein the wall board of the cylinder body is formed by multiple cylinder sections; the cylinder sections are coaxially arranged and are in bolted connection; each cylinder section is formed by multiple sections of steel plates with flange faces; the filler is added on each flange face between every two cylinder sections; the wall board of the cylinder body is formed by adopting the bolted connection; the filler is added at the joints of the flange faces of the wall board, and one flange and the filler which are adjacent are connected and fixed through the bolts; the ore feeding opening and the ore discharging opening are formed in the wall board of the cylinder body; a layer of pre-buried plate is arranged below the base plate; the space between the base plate and the pre-buried plate is connected with the ground by adopting a foundation bolt; the space between the wall board and the base plate as well as the space between the wall board and the pre-buried plate are connected with the ground by foundation bolts, so that the integral cylinder body is formed. The cylinder body is convenient to mount, various in transportation manners, high in mounting quality, high in mounting safety, and short in mounting cycle.

Description

technical field [0001] The invention relates to a large-scale mining bolt-connected steel structure cylinder in the large-scale stirring and mixing industry. Background technique [0002] Today, mining drums are a key component of common process industry equipment. At present, large-scale mining cylinders are usually welded by multiple wall panels, and their transportation method is single, and they can only be delivered in parts; when installing in the field, welding workers usually use manual arc welding, which will generate a lot of smoke and dust , soot particles permeate the working air and are easily inhaled into the lungs, causing harm to human health; due to the large volume and dead weight of the large cylinder, a large number of scaffolding and other safety protection measures need to be erected during operation; welding quality requirements Regardless of the welding method, there will always be welding residual stress after welding, which is prone to cracks, and ...

At present, large-scale mining cylinders are usually welded by multiple wall panels, and their transportation method is single, and they can only be delivered in parts; when installing in the field, welding workers usually use manual arc welding, which will generate a lot of smoke and dust , soot particles permeate the working air and are easily inhaled into the lungs, causing harm to human health; due to the large volume and dead weight of the large cylinder, a large number of scaffolding and other safety protection measures need to be erected during operation; welding quality requirements Regardless of the welding method, there will always be welding residual stress after welding, which is prone to cracks, and if the control is not in place during the welding process, it is easy to produce defects such as pores, slag inclusions, incomplete fusion, and incomplete penetration; welding The labor intensity of the workers is high, the installation period is long, and the production efficiency is low, which reduces the installation quality of the equipment
