Definitions

the invention relates to a sump for a wet blast machine of the type comprising a housing in which abrasive slurry is pumped, typically through a nozzle, turbine or the like, the abrasive slurry being incident, in use of the machine, on a component to be cleaned or stripped.
a sump for a wet blast machine of the type comprising a housing in which abrasive slurry is pumped in use, the sump comprising an outer peripheral wall the upper margin of which is adapted to be attached to the housing, the sump being provided with a protrusion spaced inwardly from the outer wall, and so arranged that a channel in the form of a continuous loop is defined between the outer wall and the inner protrusion, the side walls of the channel, that is the walls of the channel as defined by the outer wall and protrusion, being inclined.
the outer wall is integral with the protrusion.
the protrusion is located substantially in the centre of the sump, when the sump is viewed in plan.
the protrusion is located in a deepest part of the sump.
the outer wall of the sump is preferably inclined from the upper margin of the outer wall so that the sump forms a bowl.
the outer wall may, when viewed in transverse cross section or longitudinal cross section be curved, planar, or formed from a combination of curved and planar portions.
the base of the protrusion is wider than the top of the protrusion such that the protrusion is tapered.
the protrusion is of triangular transverse cross section.
the protrusion is of frustro-conical longitudinal cross section.
the protrusion may alternatively comprise a cone or a pyramid.
the cross section of the protrusion may vary along the length of the protrusion.
the side walls of the channel are inclined at an angle that is between 20 and 90 degrees to the horizontal when the sump is in use. Preferably the angle is between 35 and 55 degrees.
the side walls of the channel are inclined at an angle that is substantially 40 degrees to the horizontal when the sump is in use.
the sump further comprises a slurry agitation system, operative to agitate slurry so as to induce a flow of slurry along the channel so as to keep abrasive particles in the slurry suspended.
abrasive slurry preferably flows along the channel so as to flow around the protrusion.
the slurry agitation system comprises a pump operative to pump abrasive slurry along the channel.
the pump is operative to pump used slurry in use from the housing of the wet blast machine, and is further operative to re-circulate slurry from the sump to the housing of the wet blast machine.
a wet blast machine comprising a housing in which abrasive slurry is pumped in use, and a sump comprising an outer peripheral wall the upper margin of which is adapted to be attached to the housing, the sump being provided with a protrusion spaced inwardly from the outer wall, and so arranged that a channel in the form of a continuous loop is defined between the outer wall and the inner protrusion, the side walls of the channel, that is the walls of the channel as defined by the outer wall and protrusion, being inclined.
a sump 1 for a wet blast machine (not shown) comprises a central protrusion 3 which projects upwardly from the base, that is, the deepest part, of the sump 1.
the protrusion 3, in this example comprises two opposed inclined planar sides 5 which meet at an apex 7 of the protrusion, and two opposed, curved ends 9, each of which abuts the inclined sides 5 and the apex 7.
the protrusion 3 thus has a triangular transverse cross section when viewed from either end, as can be seen from Figure 3a, and has a frustro-conical longitudinal cross section when viewed from either side, as can be seen from Figure 3b.
the sump 1 further comprises an inclined outer peripheral wall 11.
the upper margin 13 of the outer wall 11 is adapted to be attached in use to the lower margin of a housing 12 of the wet blast machine such that abrasive slurry that is pumped in the housing 12 drops into the sump 1 after use.
a suitable seal may be incorporated as desired.
the sump 1 may be releasably attached to the housing 12 using suitable quick release clamps or the like.
the sump 1, in this embodiment, is lozenge shaped when viewed in plan, that is the sump 1 comprises two straight outer side wall portions 11A, 11B linked together by two semicircular outer side wall portions 11C. 11D.
the protrusion 3 is of similar shape when viewed in plan and is arranged to be concentric with the outer sump wall 11.
the two straight outer side wall portions 11A, 11B are substantially planar in this embodiment.
the outer side wall portions 11A to 11D are inclined to the horizontal at an angle of substantially 40°.
the sides 5 and ends 9 of the protrusion 3 are inclined at a similar angle.
the angle of inclination is chosen such that abrasive slurry incident on the wall portions 11A to 11D, and the sides 5 and end 9 of the protrusion 3, does not adhere to these surfaces, ie the angle is chosen such that the slurry slides down these surfaces towards the base of the sump 1.
most wet abrasive slurry types require an angle of substantially 40°.
the angle of inclination should be selected to achieve this effect and may vary in dependence upon the exact slurry used.
the sump is arranged such that a continuous slurry flow channel 15 is defined between the outer sump wall 11 and the protrusion 3.
the flow channel 15 is substantially oval in plan.
a slurry agitation system which comprises a pump 17 and a plurality of abrasive slurry pipes 19 each of which terminates in a respective slurry outlet which in this example comprises a nozzle 21.
a slurry outlet which in this example comprises a nozzle 21.
Any other suitable slurry outlet can alternatively be provided, including, for example, a turbine or the like.
the nozzles 21 are spaced around the channel 15 and are directed such that slurry exiting through each nozzle 21 flows around the channel 15 at a speed sufficient to maintain the abrasive particles of the slurry in suspension in the slurry liquid.
the pump 17 is provided with further pipework (not shown) to transfer abrasive slurry from the sump 1 and up into the housing of the machine.
the sump 1 may be of any shape when viewed in plan.
the sump 31 is of rectangular shape when viewed in plan.
the outer wall 33 of the sump 31 comprises four planar, vertical side portions 35 and a curved base portion 37 that adjoins the vertical side portions 35.
the angle of inclination of the curved base portion 37 is substantially 40° to the horizontal as described above.
outer wall, of the sump 1, 31, 11, 33 could comprise any combination of curved and planar portions.
Any number of circulation pipes and nozzles may also be provided. Any other suitable slurry agitation system may alternatively be provided.
baffles could be added to the channel 15 to create an area of non turbulent flow. This allows suspended abrasive to fall to the bottom of the sump 1 where the pump inlet is situated, thus increasing the concentration of the slurry that is recirculated to the housing of the machine.
Baffles could also be added to create additional turbulence in areas of the sump 1 where the agitation is insufficient to keep the abrasive in suspension.
the or each baffle can take any size and shape, including, for example, a plate that extends across the channel to fully or partially block the channel, the plate having a lower relief aperture through which the slurry can flow.
