Working principle of automatic sandblasting and shot blasting machine for profile steel

The working principle of the automatic sandblasting and shot blasting machine for profile steel:

During the cleaning process, the automatic sandblasting and shot blasting machine uses an electrically controlled variable speed conveyor roller to deliver the steel into the blasting area of the cleaning machine chamber. The surrounding surfaces are hit and rubbed by dense projectiles from different coordinate directions, causing the oxide skin, rust layer, and dirt on them to quickly fall off. The surface of the steel is given a smooth and clean surface with a certain roughness, and the workpiece is loaded and unloaded on both inlet and outlet roller tracks outside the cleaning room. The shot and rust dust that fall onto the section steel are blown by the blowing device. The mixture of shot and dust that falls is transported by the recovery screw to the chamber funnel, and is collected by the vertical and horizontal screw conveyor at the lower part of the elevator. It is then lifted into the separator at the upper part of the machine. The separated pure shot falls into the separator hopper for shot blasting circulation. Dust generated during shot blasting is sent to the dust removal system through an exhaust duct, and the purified gas is discharged into the atmosphere. Granular dust is captured and collected.

Guide for daily maintenance of automatic sandblasting and shot blasting machines for steel profiles

(1) The automatic sandblasting and shot blasting machine for section steel should be regularly inspected, maintained, and lubricated.

(2) It is strictly prohibited to stack tools, screws, and other debris inside the machine during maintenance.

(3) It is strictly prohibited to expose the pit to moisture, which may cause the bullets to rust and clump.

(4) During the operation of the automatic sandblasting and shot blasting machine for section steel, the waste in the separator and dust collector should be removed at any time to ensure the normal operation of the equipment.

(5) The water separation air filter should regularly discharge sewage and oil.
