Strong extrusion mixing dryer

Abstract

The invention discloses a strong force extrusion stirring drying machine, which comprises a machine seat, a drying rolling tube and a stirring heating roller, wherein the stirring heating roller is arranged in the drying rolling tube, and is a hollow roller provided with a steam heat supply pipeline. The gravity principle is applied to the material drying, the strong force extrusion stirring drying machine is provided with a power input shaft guide rail, a floating guide shaft guide rail and a rotating joint guide rail, so that the gravity of the stirring heating roller is completely exerted on the bottom of the drying rolling tube, the extrusion, tearing and stirring effects are achieved on the materials through the relative rotation of the stirring heating roller and the drying rolling tube, so that moisture in the wet materials is extruded out from the inside, and agglomerate materials are scattered. According to the strong force extrusion stirring drying machine, the materials are dried from the inside, and the heat energy can be totally utilized. The strong force extrusion stirring drying machine has the more obvious advantages that the stirring heating roller carries out floating adaptation under the condition of impurity existence, such as metal, in the materials, the stirring blade damage and extrusion can be avoided, the characteristics are more obvious in a recovery garbage drying process, and the obvious advantages incomparable by an ordinary roller dryer are realized.

Description

technical field [0001] The invention relates to a drying machine, in particular to a drum dryer. Background technique [0002] The drum of the prior art drum dryer is a slightly inclined and rotatable cylindrical body, the wet material enters from the upper part of one end, and the dry material is collected from the lower part of the other end. The hot air enters from the feed end or the discharge end, and is discharged from the upper part of the other end. The barrel is equipped with a forward copying plate, so that the material is continuously picked up and sprinkled during the rotation of the barrel, so that it is fully contacted with the hot air flow, so as to improve the drying efficiency and move the material forward. [0003] The disadvantages of the above drum dryer are: first, the material relies on gravity to lift the material, the agglomeration of the material is not easy to open, and drying is difficult; second, the moisture contained in the material has a large...
