To prevent the splashes of liquid chemicals sticking to a panel face by including splashing preventive plates which exist between the panel and the base of a liquid chemical tank and prevent the bouncing back of the liquid chemicals from the liquid chemical tank by developing on the circumference of the panel.
The splashing preventive plates are arranged between the roller conveyors on the circumference of the panel 20 by developing to enclose the spacings between the roller conveyors. The liquid chemicals flowing along the inner flanks of the panel 20 fall onto the ends 3 of the first splashing preventive plate 1a and second splashing preventive plate 2b projecting to the inner side of the panel 20 and are once accepted by the splashing preventive plates 2a, 2b. The liquid chemicals fall into the liquid chemical tank after flowing on these plates. The liquid chemicals falling onto the bottom plate 32 of the liquid chemical tank by colliding against the inside surface of the panel 20 are bounced back by the bottom plate 32 and side plates 31 of the liquid chemical tank by their force, by which the splashes are formed. Since the splashing preventive plates 2a, 2b close the spacings between the roller conveyors on the circumference of the panel 20, the adhesion of the liquid chemicals at the panel face 21 is prevented.
