The main structure of the pneumatic recovery sandblasting room is composed of
is mainly composed of room body, sand blasting equipment, abrasive recycling device, ventilation and dust removal device, abrasive sorting device and electric power conveying sand blasting room control device.
The main separation process is: When abrasive and dust pass through the channel, due to the action of gravity, the dust and gas come out through the gap between the cones, and the abrasive and coarse particles fall to the vibrating screen below the cone. The vibrating screen further separates the abrasive from the coarse particles, and the separated pure abrasive enters the designated hopper through the screen hole to the sandblasting tank for recycling. The dust and gas passing through the sorter are filtered through a filter, and the clean gas is discharged outside the workshop, and the dust falls into the waste hopper.
In order to simplify the equipment, the two parts of abrasive recovery and ventilation and dust removal can be combined. The fan sucks abrasives, dust, and airflow to the abrasive centralized filter through the honeycomb floor. The dust-containing gas is filtered by the filter, and the dust adheres to the outer wall of the filter. Part of the clean gas passes through the filter and is discharged to the outside of the workshop, and part is circulated to the sandblasting room. The abrasive and heavy dust continue to pass through the abrasive trough to the sorter. The separator has an inner and outer cone structure, and there is an adjustable channel between the inner and outer cones. By adjusting the core, the cross section of the air flow channel can be changed, thereby adjusting the separation ratio.
