Abstract

The invention relates to a viscous paste extruding and dehydrating device, the applied range of which includes but not limited to urban sludge dehydration and oily sludge solid-liquid separation and drying of an oil field. The device main body manly comprises a dehydrating piston, a filter element scraper device, an end face seal, a dehydrating container and a hydraulic system, wherein the dehydrating piston carries out reciprocal rectilinear motion in a cavity of the dehydrating container so as to extrude and push and discharge materials; the filter element scraper device carries out circumferential rotary motion in the cavity of the dehydrating container so as to clean and auxiliary-dehydrate a filter screen; the end face seal carries out reciprocal rectilinear motion in the cavity of the dehydrating container so as to seal and discharge materials; the dehydrating container is used for separating mud and water by virtue of the built-in filter screen; the hydraulic system provides required power and motion control for the whole viscous paste extruding and dehydrating device. The viscous paste extruding and dehydrating device provided by the invention has the characteristics of little heat consumption, high dehydrating effect, strong material adaptability, high degree of automation control and the like.

Description

Technical field [0001] The invention relates to a squeeze dehydration device, which is used for dehydrating the viscous paste (including but not limited to urban sludge, oil field oily sludge oil, etc.) after tempering treatment. The mud belongs to the technical field of chemical industry and environmental protection equipment . Background technique [0002] Viscous paste has high water content (up to 90%), high viscosity, high organic matter content, easy to rot and smell, and the particles are finer, the specific gravity is smaller, it is in a gel-like liquid state, and it is difficult to dehydrate. The drying treatment of viscous paste is divided into two categories: mechanical dehydration and thermal drying according to the different dehydration principles. At present, the mainstream adopts thermal drying technology, including convection (direct drying), conduction (indirect drying) and radiation (infrared drying) or the integration of these technologies. Before therm...
