Wet abrasive blast pot

Abstract

A wet abrasive blast pot includes a cylindrical pressure vessel have a top section, a bottom section, and sidewalls extending between the top section and the bottom section. The bottom section includes an outlet, and the top section includes a fill inlet. The top section includes a convex head, with the fill inlet located at the uppermost portion of the pressure vessel.

1 . A blast pot for use in wet abrasive blasting systems, the blast pot comprising:
 a cylindrical pressure vessel which includes sidewalls, a bottom section and a top section;   wherein the bottom section includes an outlet;   wherein the top section includes a convex head; and   wherein the convex head includes a fill inlet located at an upper most portion of the pressure vessel.   
     
     
         2 . The blast pot claimed in  claim 1  wherein the top section further includes a concave dish top, and wherein a lower most portion of the concave dish top is connected to the upper most portion of the convex head at the fill inlet. 
     
     
         3 . The blast pot claimed in  claim 2  wherein the top section further includes connecting walls that connect the sidewalls to an outer most portion of the concave dish top. 
     
     
         4 . A blast pot for use in wet abrasive blasting systems, the blast pot comprising:
 a cylindrical pressure vessel which includes:
 a bottom section; 
 an outlet in the bottom section; 
 a convex head; 
 a fill inlet located at an upper most portion of the convex head; and 
 sidewall extending between the bottom section and the convex head; and 
   a concave dish top mounted on the convex head, wherein a lower most portion of the concave dish top is connected to the upper most portion of the convex head at the fill inlet.   
     
     
         5 . The blast pot claimed in  claim 4  and further comprising:
 connecting walls that connect the sidewalls to an outer most portion of the concave dish top.
