Improved material processing system

Abstract

The invention relates to a material processing system which comprises a conveying device, a water removal structure and a drying device. The drying device comprises a furnace body, a feeding device used for adding materials into the furnace body, a collection device used for collecting dried materials in the furnace body, an air feeding device used for leading external hot gas into the furnace body through a first gas inlet, and a stirring device used for stirring and smashing the materials. When the materials are dried, hot gas is led into a cavity of the furnace body through the first gas inlet, a second rotating shaft rotates to drive a stirring assembly on the second rotating shaft to unceasingly stir the materials in the radial direction and the axial direction of the second rotating shaft, the materials can be rolled in the furnace body in the axial direction and the radial direction of the second rotating shaft, the material stirring time is prolonged, and the convection heat exchange area between the materials and hot gas is enlarged. In addition, the stirring assembly can smash the materials to form smaller-grained materials, the convection heat exchange area between the materials and hot gas is further enlarged, and the material drying efficiency and effect are improved.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to an improved material treatment system. Background technique [0002] Sludge is the product of the sewage treatment process, which contains a large amount of organic matter, heavy metals and molds, etc. If no follow-up treatment is added, it will cause serious pollution to the environment. Therefore, it is often necessary to concentrate and dehydrate the sludge, but after this treatment The moisture content of the final sludge is usually above 70%, and the sludge needs to be further dried. [0003] In the prior art, the drying system used for sludge drying is mostly structured as the drying system disclosed in the Chinese patent document CN201058838Y, including a furnace body, a feeder connected to the feed port of the furnace body, and an air outlet of the furnace body. Connected spray tower. Among them, the furnace body includes a transmission shaft arranged in the fu...
