Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting auxiliary equipment, in particular to a dust removal device and a laser cutting system. Background Art

[0002] Laser cutting machines can be used to efficiently cut sheet metal, but they generate smoke and dust during operation, which needs to be processed before being discharged. In the prior art, smoke and dust are typically sent to a cyclone separator for purification. The cyclone separator is equipped with an air inlet duct, an air outlet duct, and a slag outlet. The smoke and dust enter through the air inlet duct and then rotate downward. Due to the greater centrifugal force, the particulate impurities in the smoke and dust are separated downward to the slag outlet, while the air flow enters the air outlet duct upward and is then discharged, achieving the purpose of separating impurities. Cyclone separators are generally relatively tall, with the air inlet duct set high. The smoke outlet of a typical laser cutting machine can be set at the bottom (in addition to smoke, the cut metal slag is also produced during the cutting process. Setting it at the bottom allows these metal slag to be extracted and processed together). Therefore, during actual operation, the smoke and dust impurities may contain large-sized impurities (larger and heavier metal slag). These large impurities are difficult to lift to the high-rise air inlet duct and therefore accumulate at the bottom of the duct, seriously causing blockage and making it inconvenient to clear, affecting the normal purification operation.
