High-efficiency solid-liquid mixture processing system

Abstract

The invention relates to a high-efficiency solid-liquid mixture processing system. The system comprises a conveying device, a de-watering structure and a drying device; the drying device comprises a furnace body, a feeding device, a material receiving device, a gas supplying 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 supplying device introduces hot external gas into the furnace body through a first gas inlet, and the stirring device is used for stirring and pulverizing the materials. The stirring device comprises a second rotating shaft, the second rotating shaft is arranged in a cavity in the furnace body in a penetrating mode and provided with a ventilation cavity, the ventilation cavity is provided with multiple air-jetting openings, and the gas-jetting direction of the gas-jetting openings does not coincide with or is not parallel to the stirring direction of stirring shafts and the stirring direction of blades; when the materials are dried, the hot gas is introduced into the cavity of the furnace body through the first gas inlet, and the second rotating shaft rotates to drive a stirring assembly on the second rotating shaft to continuously stir the materials in the radial direction and the axial direction of the second rotating shaft.

Description

technical field [0001] The invention relates to the technical field of solid-liquid mixture treatment, in particular to a solid-liquid mixture 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 ar...
