Feeding device for continuous circulation drying equipment

Abstract

The invention discloses a feeding device for continuously-circulating drying equipment, which enables materials at different positions in hoppers to be uniformly fed out. The feeding device comprises an upper hopper, a middle hopper and a lower hopper which are arranged according to a charge sequence, wherein the upper hopper comprises an upper housing and an upper cover which are installed on a bottom plate, and spokes are arranged on the bottom plate and used for separating the bottom plate to form a plurality of openings; the middle hopper comprises a middle housing and a lower cover which are installed on a rack, and one end of the middle housing is connected with the bottom plate; the lower hopper comprises a lower housing installed on the rack; and a material distribution plate driven by a power is installed on the rack, at least one discharge port is formed in the material distribution plate, the bottom plate and the material distribution plate are arranged in parallel and at an interval of 1.0-1.5mm. The feeding device disclosed by the invention is simple in structure and convenient to use; during movement of the material distribution plate, because the stress conditions of the materials at different positions on the same horizontal plane above the discharge port are the same, the falling speeds of the materials are basically the same; in this way, the effect can be met that the materials discharged from the previous drying procedure can completely and uniformly enter the next drying procedure, so that the water contents of the dried materials are uniform and consistent.

Description

technical field [0001] The present invention relates to a continuous drying equipment, in particular to a feeding device of a continuous circulation drying equipment, in particular to a continuous circulation drying equipment which uniformly supplies materials at different positions in a supply hopper Feeding device. Background technique [0002] At present, the feeding hoppers used in drying equipment for powdery, granular, and small block materials generally have a large inlet, a small outlet, a large taper, and the center feeds (discharge) mouth in the middle). During the feeding process, due to gravity and friction, the falling speed of the material in the hopper gradually slows down from the middle to the edge. If the material is continuously supplied to the hopper, only a small part of the material on the edge of the hopper will fall. In this way, in the continuous circulation drying equipment, the feeding method of the traditional hopper will cause some materials t...

Problems solved by technology

In this way, in the continuous circulation drying equipment, the feeding method of the traditional hopper will cause some materials to be dried in a normal cycle, and some materials may not enter the drying equipment, so that the moisture content of the dried materials very uneven
