Air pipe component of shot blasting machine

Abstract

The invention provides an air pipe component of a shot blasting machine, and relates to surface treatment equipment, in particular to air pipes of a shot blasting machine dust removal system. The air pipe component comprises two air pipes and is characterized by further comprising a blind window; the air inlet end of the air pipe I is connected with an air intaking port, the opening of the air outlet end of the air pipe I is formed on a side surface of a lifting cylinder of a hoist; on the lifting cylinder, the opening of the air inlet end of the air pipe II is formed on a side surface relative to the opening of the air outlet end of the air pipe I, and the air outlet end of the air pipe II is connected with a dust remover; and on the lifting cylinder, the opening of the air inlet end of the air pipe II is lower than the opening of the air outlet end of the air pipe I, and the opening of the air inlet end of the air pipe II is provided with the blind window. The air pipe component has the advantages that the steel shots in the air pipes can be collected, the air discharge amount is not influenced, the height of the dust remover can be reduced, and the dust in a lifter can be purified.

Description

technical field [0001] The invention relates to surface treatment equipment, especially the air duct of the dust removal system of the shot blasting machine. Background technique [0002] When the shot blasting machine is working, due to the irregular rebound of the steel shot in the cleaning room, part of it enters the air intake of the room. A part of the steel shot is sucked away by the high-speed airflow, and another part of the steel shot sinks in the air duct. The steel shot sucked by the high-speed airflow enters the dust collector, which affects the dust removal and filtration effect and shortens the service life of the filter cartridge. The accumulation of steel shot for a long time will cause the blockage of the air duct. [0003] The usual solution is to add a pill collector to the air duct, and use the baffle in the pill collector to block the steel shot entrained in the high-speed airflow, and the shot collected in the pill collector is recycled into the equip...

AI Technical Summary

Problems solved by technology

This method effectively recovers the steel shot taken away by the high-speed airflow. The disadvantage is that the wind resistance of the pellet collector is too large. After the wind speed decreases, some heavy dust will settle in the air duct, resulting in poor dust removal effect.
