Abstract

The invention discloses a drying device. The drying device comprises a furnace body, a charging device for charging a material into the furnace body, a collecting device for collecting a dried material in the furnace body, an air supply device for inducing external hot gas into the furnace body by a first gas inlet, and a stirring device for stirring and pulverizing the material, wherein the stirring device comprises a rotary shaft which penetrates through a cavity of the furnace body, the rotary shaft is provided with a venting cavity provided with a plurality of gas nozzles, the gas spraying direction of the gas nozzles is misaligned and not parallel with the stirring direction of the stirring device and the stirring direction of blades, during material drying, the hot gas is induced into the cavity of the furnace body by the first gas inlet, and the rotary shaft rotates to drive a stirring assembly on the rotary shaft to continuously stir the material along the axial direction and radial direction of the rotary shaft, so that the material is turned over in the furnace body along the axial direction and radial direction of the rotary shaft, the stirring time of the material is prolonged, and a convection heat exchange area between the material and the hot gas is increased. In addition, the stirring assembly can pulverize the material to form a material of smaller particles, thus further increasing the convection heat exchange area between the material and the hot gas and improving the drying efficiency and drying effect of the material.

Description

technical field [0001] The invention relates to the technical field of heating and drying, in particular to a drying 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 furnace body, a number...
