Pollutant treatment device for production line of asphalt mixing plant

Abstract

The invention provides a pollutant treatment device for a production line of an asphalt mixing plant. The pollutant treatment device comprises a stirring tank body used for asphalt stirring processing, supporting legs used for supporting the stirring tank body and a self-cleaning filtering mechanism used for filtering emissions generated in asphalt production. The supporting legs are fixedly installed at the bottom of the stirring tank body, and a driving motor is fixedly installed at the bottom of the stirring tank body. The present invention relates to the field of asphalt processing. The pollutant treatment device for the production line of the asphalt mixing plant solves the problem of pollutants existing in the existing asphalt mixing process; a self-cleaning special structure capableof adapting to a small-aperture filter screen is designed, the problem of blockage of the filter screen can be solved in time, waste materials can be recycled in time, noise of the equipment is reduced, and therefore the problems that a large number of easily-stuck harmful substances are generated by common asphalt stirring and processing equipment, the filtering effect of a large-aperture filterscreen is poor, a small-aperture filter screen needs to be cleaned frequently, and the asphalt production and processing efficiency is affected are effectively solved.

Description

technical field [0001] The invention relates to the technical field of asphalt processing, in particular to an asphalt mixing plant production line pollutant treatment device. Background technique [0002] The asphalt mixing plant is a complete set of equipment for mass production of asphalt concrete. During production, the sand and gravel materials are turned into hot materials through feeding, drying, vibrating screening and metering operations, and then the hot materials, asphalt oil and mineral powder are weighed and measured. After that, it is stirred according to a certain proportion to become asphalt mixture, in which dust is generated in the processes of sand and gravel material feeding, drying and vibration screening, and asphalt smoke is also generated during the mixing process of asphalt mixture. Easy adhesion, solid and liquid particles condensed by asphalt volatile components, and organic matter in steam state, some of which are high molecular polymers, which wi...
