[0002] In order to ensure the stability of the straightening process, improve the surface quality of the product and meet the needs of high-speed production of thin strip, it is required to configure a cleaning device in the aluminium strip stretch bending straightener unit.

[0003] The stretch bending straightener cleaning unit uses solvent oil to clean, and the solvent oil is atomized to flush the impurities and oil spots attached to the surface of the aluminium plate strip through an atomizing device. Since the flash point of the solvent oil is low, it is easy to catch fire after atomization, and therefore a high-temperature alarm and a CO2 fire extinguishing device are required.

[0004] The traditional high-temperature alarm transmits temperature data through a contact thermocouple, and then displays the temperature data on a picture and reminds the operator through a sound and light alarm lamp. The operator then manually extinguishes the fire by checking the fire condition in combination with the monitor.

[0005] The traditional manual fire extinguishing method is to place a certain number of high-pressure CO2 fire extinguishing tanks near the atomizing unit and the oil storage tank area, and then manually open the valve to extinguish the fire by the worker. This requires multiple workers to operate a group of high-pressure CO2 fire extinguishing tanks to extinguish the fire, which greatly reduces the fire extinguishing speed and the safety of the workers on site.
