A granulating drying oven screening system

Abstract

The utility model discloses a granulating drying box screening system, include: oven body, the air -permeable layer board is arranged in the oven body and will the oven body divide into the air intake aggregate chamber and is located the drying chamber above the air intake aggregate chamber, is equipped with the feed inlet with the drying chamber intercommunication on the oven body, is equipped with the air -permeable hole with the drying chamber intercommunication on the oven body lateral wall, is equipped with the discharge gate with the drying chamber inside intercommunication on the oven body, the air -permeable layer board includes the screening mesh hole section, and the screening mesh hole section is full of screening mesh hole, and the particle size of qualified bead is greater than the aperture of screening mesh hole is greater than the aperture of air -permeable hole, gas source device has the gas pipe, and the gas pipe is inserted in the air intake aggregate chamber and is located the position close to the air -permeable layer board lower end, and the gas pipe is used for sending the drying gas source upwards. The unqualified smaller bead is separated out through the screening mesh hole in the bead drying process, reduces the unnecessary energy consumption, and improves the energy efficiency.
