Sludge treatment system

Abstract

The invention relates to a sludge treatment system which comprises a conveying device, a water removal structure and a drying device. The drying device comprises a furnace body, a feed device used for adding materials into the furnace body, a material collection device used for collecting the dried materials in the furnace body, an air supply device used for leading external hot air into the furnace body through a first air inlet, and a stirring device used for stirring and smashing the materials. When the materials are dried, hot air is led into a cavity of the furnace body through the first air inlet, a second rotating shaft rotates and drives 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, and therefore the materials can roll in the axial direction and the radical direction of the second rotating shaft in the furnace body, the time during which the materials are stirred is prolonged, and the convective heat exchange area of the materials and hot air is enlarged. In addition, the materials can be smashed through the stirring assembly, materials with smaller particles can be formed, the convective heat exchange area of the materials and hot air 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 sludge 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 furn...
