Abstract

The invention discloses a circulation drying device, comprising a furnace body, a feeding device for adding materials into the furnace body, a material receiving device for collecting dried materials in the furnace body, and introducing hot gas from the outside through a first air inlet. The air supply device in the furnace body, and the stirring device for stirring and crushing the materials. Wherein, the stirring device includes a rotating shaft, which is installed in the cavity of the furnace body. The rotating shaft has a ventilating cavity, and several air injection ports are arranged on the ventilating cavity. The stirring directions of the blades and the stirring directions of the blades do not coincide and are not parallel; when the material is dried, the hot gas is introduced into the cavity of the furnace body through the first air inlet, and the rotation of the rotating shaft drives the stirring assembly on the rotating shaft to move in the radial direction of the rotating shaft. The material is continuously stirred in the axial and axial directions, so that the material can roll in the axial and radial direction of the rotating shaft in the furnace body, increasing the time for the material to be stirred, and increasing the convective heat exchange area between the material and the hot gas.

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...
