Improved solid-liquid mixture treatment system

Abstract

The invention discloses an improved solid-liquid mixture treatment system. The system comprises a transmission device, a dewatering structure and a drying device, wherein the drying device comprises afurnace body, a feeding device, a material receiving device, an air supply device and a stirring device, wherein the feeding device is used for feeding materials into a furnace body, the material receiving device is used for collecting the materials dried in the furnace body, the air supply device is used for introducing external hot air into the furnace body through a first air inlet, and the stirring device is used for stirring and crushing the materials; and the stirring device comprises a second rotating shaft, the second rotating shaft penetrates a cavity of the furnace body, the secondrotating shaft is provided with a ventilation cavity, a plurality of air jet holes are formed in the ventilation cavity, the air injection directions of the air jet holes are misalign and are not parallel to the stirring directions of stirring shafts and the stirring directions of blades; and when the materials are dried, the hot air is introduced into the cavity of the furnace body through the first air inlet, the materials can roll in the furnace body in the axial direction and the radial direction of the second rotating shaft, the time for stirring the materials is increased, and the area of convective heat exchange between the materials and the hot air is increased.

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. [0002] The present invention is a divisional application, the application number of the parent case is: 201610007730.3, the title of the invention is: an improved solid-liquid mixture processing system, the applicant is: Wang Liangyuan, and the application date is: January 6, 2016. Background technique [0003] 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. [0004] In the prior art, the drying system used for sludge drying is mostly...
