An improved solid-liquid mixture processing system

Abstract

The invention relates to an improved solid-liquid mixture 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 device for collecting The material receiving device for the dried material, 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 crushing the material. Wherein, the stirring device includes a second rotating shaft, which is installed in the cavity of the furnace body. The second rotating shaft has a ventilating cavity, and several air jets are arranged on the venting cavity. The stirring direction of the stirring shaft and the stirring direction of the blades do not overlap and are not parallel; 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 gas on the second rotating shaft. The stirring assembly continuously stirs the materials along the radial and axial directions of the second rotating shaft.

Description

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