An Improved Sludge Treatment System

Abstract

The invention relates to a sludge treatment system. The sludge treatment system comprises a transmission device, a water removal structure and a drying device, wherein the drying device comprises a furnace body, a feeding device, a material receiving device, a gas supply device and a stirring device, wherein the feeding device is used for feeding materials into the furnace body, the material receiving device is used for collecting dried materials in the furnace body, the gas supply device is used for introducing external hot gas into the furnace body through a first gas inlet, and the stirring device is used for stirring and grinding the materials. When the materials are dried, hot gas is introduced into a furnace body cavity through the first gas inlet, a second rotating shaft rotates to drive a stirring assembly on the second rotating shaft to continuously stir the materials along the radial and axial directions of the second rotating shaft, and then the materials can roll in the furnace body along the radial and axial directions of the second rotating shaft, so that the stirring time of the materials is prolonged, and the heat convection area between the materials and hot gas is increased; and besides, the materials can be ground into the materials with relatively small particles by the stirring assembly, so that the heat convection area between the materials and hot gas is further increased, and the drying efficiency and drying effect of the materials 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...
