Abstract
A slurry recovery system for a wet cutting saw which includes a watering section, a containment section, a gas-liquid separator section and a discharge section. The watering section contains a pressure gauge, shut-off valve and flowmeter to control the flow of liquid onto the saw blade. The containment section includes a blade cover and bellows which surround the saw blade and form a sawing chamber. A drag bar, which is attached to the lower surface of the bellow, skids along the cutting surface and removes the slurry therefrom. The drag bar includes inner and outer flexible walls that create a vacuum chamber around the saw. The slurry is vacuumed out of the vacuum chamber and conveyed to a gas-liquid separator tank, wherein the slurry and air are separated. The slurry passes to a diaphragm pump and the air passes to a discharge blower. The separator tank includes a blower protector which contains a float and seals. When the slurry level rises above a desired level, the float prevents slurry from passing through an air outlet port. The slurry is drawn from the separator tank, via a diaphragm pump and a surge tank, and is stored in a holding tank for disposal.
