Abstract

A water jet cutting apparatus has a line catcher for water and abrasive passing through the worktable comprising a carriage on the frame is movable above a pervious worktable and carries a water jet cutting head. A pan ia supported on the frame and spaced below the worktable, and a collector extends transversely of the frame between the worktable and pan for movement along the length of the worktable in alignment with the cutting head, and has a drain. An insert member is supported in the collector and drains into the collector. A settling tank cooperates with a sludge pump with a conduit from the pan to the settling tank to transport water and abrasive material to the tank. A rinsing pump has a conduit from the settling tank to the collector to draw water from the settling tank and flush abrasive from the collector outwardly of the drain into the pan.

Dependent claims

A water jet cutting apparatus having a line catcher for water and abrasive passing through the worktable, comprising:

(a) a frame;
(b) a pervious worktable on the frame;
(c) a carriage on said frame above said worktable and movable thereover;
(d) a water jet cutting head on said carriage;
(e) a pan supported on said frame and spaced below said worktable;
(f) a collector extending transversely of the frame and supported thereon between said worktable and pan for movement along the length of said worktable in alignment with said cutting head, said collector having end, side and bottom walls, said collector having a drain for flow of water and abrasive therefrom and into said pan;
(g) an insert member of generally polygonal cross section supported in said collector and having end, side and bottom walls, said bottom wall being spaced from said bottom wall of said collector and having a drain for flow of water and abrasive therethrough;
(h) a settling tank;
(i) a sludge pump with a conduit from said pan to said settling tank to transport water and abrasive material to said tank;
and
(j) a rinsing pump having a conduit from said settling tank to said collector to draw water substantially free from abrasive from the top of said settling tank and to pump the water to said collector to flush abrasive from said collector outwardly of said drain into said pan.

(a) a frame;
(b) a pervious worktable on the frame;
(c) a carriage on said frame above said worktable and movable thereover;
(d) a water jet cutting head on said carriage;
(e) a pan supported on said frame and spaced below said worktable, said pan being configured to cause water and abrasive material to flow towards a collection area;
(f) a collector extending transversely of the frame and supported thereon between said worktable and pan for movement along the length of said worktable in alignment with said cutting head, said collector having end, side and bottom walls, said collector having a drain for flow of water and abrasive therefrom and into said pan, said cutting head and line catcher being moved synchronously;
(g) an insert member supported in said collector and having a polygonal cross section with end, side and bottom walls, said bottom wall being spaced from said bottom wall of said collector and having a drain for flow of water and abrasive therethrough;
(h) deflecting material in said insert member;
(i) a settling tank;
(j) a sludge pump with a conduit from said collection area of said pan to said settling tank to transport water and abrasive material to said tank;
and
(k) a rinsing pump having a conduit from said settling tank to said collector to draw water from said settling tank and to pump the water to said collector to flush abrasive from said collector outwardly of said drain into said pan.
