Abstract

The invention discloses a drying device comprising a furnace body, a feeding device, a material receiving device, an air feeding device and a stirring device. The feeding device is used for adding materials into the furnace body. The material receiving device is used for collecting the dried materials in the furnace body. The air feeding device introduces external hot air into the furnace body through a first air inlet. The stirring device is used for stirring and crushing the materials. The stirring device comprises a rotating shaft which penetrates into a cavity of the furnace body. The rotating shaft is provided with an air-through cavity. The air-through cavity is provided with a plurality of air jet holes, and the air jet directions of the air jet holes are neither overlapped with notparallel to the stirring direction of the stirring shaft and the stirring direction of a blade. When the materials are dried, the hot air is introduced into the cavity of the furnace body through thefirst air inlet, the rotating shaft rotates to drive the stirring device on the rotating shaft to continuously stir the materials in the radial and axial directions so that the materials can roll inthe furnace body in the axial and radial directions, the stirred time of the materials is increased, and the convection heat exchange area between the materials and the hot air is increased.

Description

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