Cutting slag gas-liquid two-phase clearing device

Abstract

The invention discloses a cutting slag gas-liquid two-phase clearing device. The device comprises a slag clearing box, a cutting head, a spraying pump, a water tank, a reflux pump and a water outlet fine filtering device, wherein the slag clearing box is installed below the cutting head, two spraying pipes are arranged in the top of the slag clearing box and connected with the spraying pump, the water inlet end of the spraying pump is connected with the water inlet fine filtering device, the water inlet end of the water inlet fine filtering device is connected with the water tank, the middle of the slag clearing box is provided with a dust removing suction opening used for discharging cleaning liquid spray and steam, and a dust removing water pumping opening used for discharging cleaning liquid is formed in the lower portion of the slag clearing box. According to the device, the water-based cleaning liquid is used for forming a spacer liquid film on the surface of a laser seam structural member and forming the spray in a laser seam space, cutting slag is rapidly cooled, the sintering effect of the cutting slag is avoided, slag collection is avoided, and meanwhile, the liquid film on the surface of the laser seam structural member can prevent the cutting slag from being sintered and adhered and can also scour the cutting slag.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a gas-liquid two-phase cleaning device for slag cutting. Background technique [0002] It is a common phenomenon in the industry that the slag generated by laser cutting accumulates on the cutting machine. The use of dust removal fans can improve the air quality of the environment, but slag collection cannot be avoided. [0003] During the cutting process, the slag produced has two forms, namely dust and particles. Under the action of the high-speed airflow injected by the cutting head, the high-temperature slag flies away from the slit and encounters obstacles, causing three consequences: [0004] (1) Sticking to obstacles to form slag-collecting particles; [0005] (2) Sintering on the slag formed in the early stage, causing the slag to grow; [0006] (3) Rebound to support belts, blanking parts and blanks. [0007] The problem of slag collection will serious...
