The invention discloses an induced-draft liquid receiving device for multiple materials. The induced-draft liquid receiving device comprises a barrel-opening draft hood and a liquid receiving plate positioned in the draft hood, wherein the barrel-opening draft hood adopts a form combining two semicircular cones with two inclined surfaces; the liquid receiving plate comprises a plate body, lug plates, a positioning plate and a spacing plate; the plate body adopts a conical ring form, and comprises an inner ring plate, an outer ring plate, two side plates and a bottom plate; the inner ring plate and the outer ring plate are arranged in an inclined mode in a vertical direction, so that the area of the upper cross section of the plate body is greater than that of the lower cross section of the plate body; the outer ring plate is greater than the inner ring plate in dimension in both of length and height directions; the two side plates are vertically arranged; and the lug plates are positioned on the upper edges of the side plates. According to the induced-draft liquid receiving device, the induced-draft effect and the liquid-receiving effect are simultaneously reinforced by virtue of a design combining the draft hood with the liquid receiving plate; the liquid receiving area is increased by adopting a design form, which is wide at the top and is narrow at the bottom, of the plate body; the pacing plate is arranged in the plate body for dividing the area of the plate body, so that the liquid receiving plate can receive different chemical materials without frequently pouring waste; and the liquid receiving plate is stable to place because of the designs of the positioning plate and the lug plates, so that an unexpected material pouring condition is avoided.
