Problems solved by technology

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

Abstract

A large mine bolted steel structure cylinder used in the mixing and mixing industry, including wall plates, bottom plates, embedded plates, ore inlets, ore discharge ports, fillers, bolts, and the wall plates of the cylinder body are composed of multi-section cylinders The barrel section is arranged coaxially and is composed of bolts; the barrel section is composed of multi-section steel plates with flange surfaces, and fillers are added to the flange surfaces between the barrel sections and the barrel sections are connected by bolts to form the barrel body. Wall plate; fillers are added to the joints of each flange surface of the wall plate, and the adjacent flanges and fillers are connected and fixed with bolts; the wall plate of the cylinder is provided with an ore feeding port and a mine discharge port; The buried plate, the bottom plate and the embedded plate are connected to the ground with anchor bolts; the wall plate, the bottom plate, and the embedded plate are connected to the ground with anchor bolts to form a complete cylinder. The device is easy to install, has various transportation methods, high installation quality, high installation safety and short installation period.

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 cylinders are a key component of common process industry equipment. At present, large-scale mining cylinders are usually welded by multiple wall plates. The transportation method is single, and they can only be shipped in bulk. When installing on-site in the field, welders usually use manual arc welding, which will generate a lot of smoke and dust. , smoke and dust particles are diffused in the working air and are easily inhaled into the lungs, causing harm to human health; due to the large volume and weight of the large cylinder, a large number of scaffolding and other safety protection measures are required during operation; welding quality requirements No matter what kind of welding method, there is always welding residual stress after welding, which is easy to produce cra...
