Technical Field

The invention belongs to the technical field of hot-rolled steel sheet pile production equipment, and particularly relates to a hot-rolled steel sheet pile oxide skin recycling and dust removing device.

Background

The hot-rolled steel sheet pile is similar to the production process of other hot-rolled sections, and is subjected to the working procedures of heating, rolling, cooling and straightening, sizing and cutting and the like. After cooling, a layer of oxide scale (generally blue) is formed on the surface of the section bar, and after straightening, the layer of oxide scale is cracked and peeled off. For the U-shaped hot-rolled steel sheet pile, oxide skin on the outer side can scatter around the straightening machine, the cleaning workload is large, and the production site is untidy; the intraoral cinder of basin can drop in the web, if not in time the clearance will influence the outward appearance of product, the transportation also can be blown away polluted environment. In the prior method, the oxide skin in the web is blown away by a high-pressure air pipe, so that the environment is polluted and waste is caused; the adoption of the cover type dust removing equipment has poor dust removing effect and low oxide skin recovery rate, thus causing certain waste. Because the scale can be used for sintering and steelmaking production, if the scale can be recycled, the scale can be supplied to a steel plant to reduce the production cost.

Chinese patent with application No. 2020201754971 discloses an environmental protection, energy saving, dust pelletizing system is retrieved to hot rolling steel sheet pile cinder of falling this, including the straightener, the dust absorption pipeline, the dust remover, band conveyer, the collecting box, fixed nylon brush device, set up fixed nylon brush device and dust absorption pipeline in proper order in discharge gate one side of straightener, be equipped with band conveyer below straightener steel sheet pile orbit, the collecting box sets up the discharge end at band conveyer, under the fixed nylon brush device, the dust absorption pipeline is connected with the dust remover, the dust absorption mouth and the steel sheet pile web size phase-match of dust absorption pipeline stretch into in the steel sheet pile basin mouth of operation, nylon brush and the steel sheet pile basin mouth phase-match in the fixed nylon brush device stretch into in the steel sheet pile basin mouth of operation.

It can make the cinder partially retrieve, especially passes through the cooperation of brush and dust absorption pipeline to the cinder in the basin mouth, not only consumes the energy, and the recovery effect is limited moreover.

The Chinese patent with the application number of 2020202148719 discloses an environmental protection, energy-conserving hot rolling angle steel cinder clearance, recovery and dust pelletizing system again, the straightening process at the angle steel production line is arranged to the system, including descaling cleaning device, dust collecting equipment, water dust collector, cinder collection device in advance, descaling cleaning device sets up before the straightener entry in advance, is equipped with cinder collection device in descaling cleaning device and straightener bottom in advance, and water dust collector sets up between the straightener roll of straightener, and dust collecting equipment connects descaling cleaning device in advance.
