Abstract

The utility model is an upright drying machine consisting mainly of a circular disc feeder and a cylinder which is arranged with a feed pipe, a firebox, a chimney and a dump bucket. A group of cone-shaped filter cones are arranged along the inner wall of the cylinder and a group of umbrellalike stock stopping cores are arranged in cavities of the cone-shaped filter cones in the laminated compound way. A group of exhaust tubes assembled with a blower are arranged on the outer wall of the cylinder. Anabatic thermal currents of high temperature folded in layer into the group of cone-shaped filter cones exchange heat with settling material flows formed by stepwise settlement of materiel put in by a feed pipe along the group of cone-shaped filter cones in order to dry materiel. Ash and dust in the currents are intercepted, stopped and filtered by the settling material flows. A water vapor is pumped to an exhaust pipe by the exhaust tubes and then pollution-free discharge of high altitudes is processed. The utility model has rational design, strong drying ability and convenient operation and use; the drying machine having small area, high thermal efficiency, low power consumption and coal consumption has great prospects of promotion and application.
