Abstract

The invention discloses a drying system which comprises a furnace body, a material feeding device for adding materials into the furnace body, a material collecting device for collecting the materials dried in the furnace body, a wind feeding device for introducing outside hot gas into the furnace body through a first air inlet, and a stirring device for stirring and pulverizing the materials, wherein the stirring device comprises a rotating shaft arranged in the cavity of the furnace body in a penetrating manner, and stirring assemblies arranged on the rotating shaft. When the materials are dried, the hot gas is introduced into the cavity of the furnace body through the first air inlet, and the rotating shaft rotates to drive the stirring assemblies on the rotating shaft to continuously stir the materials in the radial direction and the axial direction of the rotating shaft, so that the materials can overturn in the axial direction and the radial direction of the rotating shaft in the furnace body, the time of stirring the materials is prolonged, and the heat convection area of the materials and the hot gas is enlarged. Besides, the stirring assemblies can also pulverize the materials to form the materials with relatively small particles, the heat convection area of the materials and the hot gas is further enlarged, and the drying efficiency and the drying effect of the materials are improved.

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...
