Background
With the rapid development of economic construction in China, the market demand for rolling mills with purging assemblies is increasing day by day. It is known that in the straightening and withdrawal sections of a pickling line, the physical shape of a scale breaking roller, a straightening machine and a withdrawal straightening machine is changed during working, so that more fine iron oxide powder is generated on the surface of the cold-rolled strip steel. If the fine iron oxide powder is not effectively collected, part of the iron oxide powder can be brought into the withdrawal and straightening machine, and the iron oxide powder can be pressed into the strip steel through rolling by the withdrawal and straightening machine, so that indentations are generated on the surface of the strip steel, small pits are easily formed on the surface of the strip steel after acid pickling, and the surface quality of the strip steel is seriously affected. In addition, the falling iron powder can affect the working environment of the area and is extremely not beneficial to the health of operators. At present, the blowing components are mainly arranged in front of and behind the straightening and withdrawal roll, and most nozzles of the blowing components are air knife multi-hole air nozzles and flat duckbills. The air knife multi-hole air nozzle is mainly of a 360-degree axisymmetric nozzle type, so that fine iron oxide powder blown by the nozzle is blown to a higher air space to influence the work of the dust collection device, and the air pump can provide higher pressure to influence the economic benefit; the fine iron oxide powder on the flat duckbill sweeping strip metal plate needs relatively high pressure provided by an air pump, and the economic benefit is high. The purging pipes in factories are mostly cast, and if one of the purging pipes is worn or fails due to other reasons, the purging pipe cannot be disassembled and assembled and is scrapped, so that the cost is increased. The traditional dust suction device is fixedly arranged below a strip, a dust removal system almost adopts a mode of adding air suction hoods on the upper surface and the lower surface of strip steel which is continuously conveyed and runs, sucked dust-containing gas is sent into a dust remover through a dust removal air pipe, and then fine iron oxide powder blown in the air is sucked away by the suction force of the dust suction device, so the required dust suction device has high power, the blowing and dust suction cannot form circulation, and the economic benefit of an enterprise is influenced.
Because the sweeping component and the dust suction device in the conventional sweeping room cannot form circulation when working, the power required by the device is larger, and the fine iron oxide powder is not cleaned, the fine iron oxide powder which is not cleaned is pressed into the strip when the strip is pulled and straightened by the pulling and straightening roller, so that the surface of the strip is damaged to form a pit, and the quality of the strip and the economic benefit of an enterprise are influenced.
