Novel steel rust removing device and rust removing method of steel

Abstract

The invention belongs to the field of a machine, particularly relates to a novel steel rust removing device, which comprises a roller way, a rust removal plate and vibrators arranged above the rust removal plate. Steel to be dedusted is arranged between the roller way and the dust removal plate; a gap is arranged between the dust removal plate and the steel to be derusted; two vibrators are symmetrically arranged above the rust removal plate; the rust removal plate is made of an FRP (fiber reinforce plastic) board with a sharp angle; the sharp angle is arranged under the dust removal plate; the distribution density of the sharp angle on the FRP board is 900 per square meter; a group of movable shafts are uniformly arranged above the dust removal plate; the dust removal plate is connected with a lifting platform through the movable shafts; the lifting platform is connected with a computer; and the position of the dust removal plate on the steel to be derusted is controlled by the computer through the movable shafts. The novel steel rust removing device disclosed by the invention has the advantages of simple structure, large and overall dust removal quantity, uninterrupted dust removal, high work efficiency, labor and force conservation and the like. A plurality of small concave spots are formed on the surface of the steel in dust removal, and the contact area between a coating and the surface of the steel is greatly increased at the following anticorrosive coating stage.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a novel steel derusting device and a derusting method thereof. Background technique [0002] With the development of the economy, the city is changing rapidly, and large-scale construction is in full swing everywhere. Steel is widely used in the construction industry, but steel is inevitably rusted and contaminated with dirt, oil and other impurities during transportation and storage. Therefore, steel must be derusted and decontaminated before use. Traditional derusting methods include manual derusting, chemical derusting and mechanical derusting. Among them, the speed of manual derusting is slow, the labor intensity is high, and the efficiency is low; the effect of chemical derusting is not ideal, which can cause environmental pollution; the shot blasting and sandblasting treatment in mechanical derusting can cause environmental problems, and it will damage the surface of the steel, a...
