Description

Technical Field

[0001] The utility model relates to a screening hopper, in particular to a conveniently disassembled multi-layer vibrating dryer screening hopper, belonging to the technical field of dryers. Background Art

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The dryer heats the material to vaporize the moisture (generally refers to water or other volatile liquid components) to obtain solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. According to the operating pressure, dryers are divided into two categories: atmospheric pressure dryers and vacuum dryers. According to the operating pressure, they can be divided into atmospheric pressure dryers and reduced pressure dryers.

[0003] Authorization announcement number (CN212870675U) discloses a screening hopper for a dryer, comprising: a hopper body, a panel enclosed on the top of the hopper body, and a screening plate plugged and fixed in the panel; the longitudinal section of the hopper body is an inverted right-angled trapezoid; the long bottom side of the hopper body is a feed inlet, and the discharge port of the hopper body is provided on the right-angled side; a plurality of screening holes are provided on the screening plate; a drawer plate is provided below the screening plate, and a blocking hole corresponding to the screening hole is provided on the drawer plate, and the blocking hole is a sphere, wherein small-sized materials pass through the screening hole and the blocking hole in turn and then fall into the hopper body, and large-sized materials pass through the screening hole and are blocked by the blocking hole, and the drawer plate is pulled out to dump the large-sized materials;

[0004] Although the above patented technology solves the problem of wasting drying time when materials of different sizes are fed and dried at the same time, improves drying efficiency and saves drying costs, its hopper may not be convenient to disassemble.
