Abstract
The tank (10) is for use with liquid-jet-cutting equipment for reception therein of the spent, liquid-jet-cutting liquid, and comprises a receptacle (12) having side (18, 20) and end (14, 16) walls joined to a bottom which slopes inwardly and downwardly to a drain hole (28) formed in one of the walls. Arrayed along one wall, immediately above the bottom, is a plurality of apertures (30) for accommodating washing fluid therethrough for cleaning the bottom of scrap, cuttings and such detritus. Ablative plates are set upon the bottom, in overlapped fashion, to receive the liquid-jet of the equipment, and to dissipate its energy.
Description
- This invention pertains to liquid-jet-cutting equipment, and in particular to catcher tanks, i.e. receptacles, for the spent, liquid-jet-cutting liquid used in such equipment.
- It is an object of the invention to set forth a catcher tank, for spent, liquid-jet-cutting liquid, comprising a receptacle; said receptacle having a pair of opposed, substantially vertical, end walls joined to a pair of opposed, substantially vertical, side walls, and a bottom, joined to all said walls; wherein said bottom is joined to all said walls, as aforesaid, at oblique/acute angles relative to at least one of said walls of one of said pairs thereof.
- Further objects of the invention, as well as the novel features thereof, will become more apparent by reference to the following description, taken in conjunction with the accompanying figures, in which:
- Figure 1 is a plan or top view of the novel catcher tank;
- Figure 2 is a side elevational view with a portion of the side paneling cut away to show the bottom therein; and
- Figure 3 is an end elevational view, again with a portion of end paneling cut away to show some detail of the bottom and the handhole.
- As shown in the figures, the
tank 10 comprises areceptacle 12 having a pair of opposed, vertical,end walls side walls receptacle 12 is designed to be used dry, i.e., no liquid is to accumulate therein. Consequently, thereceptacle 12 has abottom 22, joined to each of the walls, which slopes to the transverse center 24, and is also inclined to define a trough having lowermost locus orpoint 26. The oneside wall 18 has adrain hole 28 formed therein, in immediate adjacency to the aforesaid locus orpoint 26, through which to evacuate the spent, liquid-jet-cutting liquid from thetank 10. - The
opposite side wall 20 has a plurality ofapertures 30 formed therein, also in immediate adjacency to thebottom 22, to accommodate flushing/washing nozzles (not shown) for washing fluid to cleanse the bottom of scrap, cuttings and such detritus. - Commonly, liquid jets comprise an abrasive and, for that reason, the
tank 10 uses ablative plates (not shown) which occupy thebottom 22, and are emplaced thereon in overlapped fashion, to dissipate the energy of the liquid jet -- be it solely liquid or liquid and abrasive. - The
side wall 20, which has the plurality ofapertures 30 arrayed therein, also has ahandhole 32 formed therein. Acover 34 keeps thehandhole 32 closed off when the handhole is not being used for inspection, adjustment of the aforesaid ablative plates, etc. - In each pair of opposed,
parallel walls vent holes 36. These allow for the exhaust of excess vapor fromthetank 10. Frequently, the materials being cut by the liquid jet are such as need to be kept dry and, if the accumulating liquid vapors cannot escape from thetank 10, they can rise through the cut kerf and dampen the materials. Thevent holes 36 provide for the escape ofthe vapors. - Figure 1 shows but a fragment of the chrome-plated,
steel grate 38, which is set upon the top of thereceptacle 12. It is sacrificial and readily replaceable.
Claims (5)
1. A catcher tank, for spent, liquid-jet-cutting liquid, comprising a receptacle (12); said receptacle having a pair of opposed, substantially vertical, end walls (14, 16) joined to a pair of opposed, substantially vertical, side walls (18, 20), and a bottom (22), joined to all said walls, characterised in that said bottom is joined to all said walls at oblique/acute angles relative to at least one of said walls of one of said pairs thereof to define, of said bottom, a sloping trough having a lowermost locus or point (26); and one of said walls has a drain hole (28) formed therein in immediate adjacency to said locus or point for evacuating spent liquid therethrough from said trough.
2. A catcher tank according to claim 1, characterised in that said bottom is joined to all said walls at oblique/acute angles relative to at least one pair of said opposed walls.
3. A catcher tank according to claim 1 or 2, characterised in that one wall of one of said pairs of walls has a plurality of apertures (30) formed therein, in adjacency to said bottom, for accommodating washing fluid to cleanse said bottom.
4. A catcher tank according to claim 3, characterised in that said one wall of said one pair of walls, having said apertures (30) therein, also has a handhole (32) formed therein.
5. A catcher tank according to any one of the preceding claims, characterised in that each pair of walls has vent holes (36) formed therein, cater-cornered from each other, to accommodate for the escape therethrough of excess liquid vapours.
