Large tank for plant for immersion treatment of objects has end walls of tank body curved in circle arc form in cross section but includes angle smaller than 180 degrees so that they change into sidewalls with comparatively sharp edges

摘要

The large tank for a plant for immersion treatment of objects has the end walls (7,8) of the tank body (2) curved in circle arc form in cross section but includes an angle which is smaller than 180 degrees so that they change into the sidewalls (4,5) with comparatively sharp edges (10-13). Reinforcing ribs (16) are provided only in the region of the sidewalls and not in the region of the end walls. The bottom of the tank is also curved in circle arc form in cross section but includes an angle which is smaller than 180 degrees so that it changes into the sidewalls (4,5) with comparatively sharp edges.
