Abstract

The invention relates to a sludge treatment system, which includes a transmission device, a water removal structure and a drying device. The drying device includes a furnace body, a feeding device for adding materials to the furnace body, and a collection of dried materials in the furnace body. The material receiving device, the air supply device that introduces the external hot gas into the furnace body through the first air inlet, and the stirring device for stirring and pulverizing the materials. When drying the material, the hot gas is introduced into the cavity of the furnace body through the first air inlet, and the rotation of the second rotating shaft drives the stirring assembly on the second rotating shaft to continuously stir the material along the radial and axial directions of the second rotating shaft , so that the material can roll along the axial and radial directions of the second rotating shaft in the furnace body, increase the time for the material to be stirred, and increase the convective heat exchange area between the material and the hot gas. In addition, the stirring component can also crush the material to form a material with smaller particles, further increase the convective heat exchange area between the material and the hot gas, and improve the drying efficiency and drying effect of the material.

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...
