Environment-friendly old asphalt thermal regeneration equipment with washing function and method

Abstract

The invention discloses environment-friendly old asphalt thermal regeneration equipment with a washing function. The equipment comprises a cleaning box; a cleaning assembly for cleaning old asphalt isarranged in the cleaning box; a crushing assembly for crushing the old asphalt is arranged at the top end of the right side of the cleaning box; a discharging opening is formed in the lower end of the left side of the cleaning box; a reaction assembly for heating and regenerating the old asphalt is arranged on the right side of the cleaning box and located under the discharging opening; the design is reasonable, the cleaning assembly is arranged to effectively clean the old asphalt; some impurities in the old asphalt can be effectively removed, the regeneration effect of the old asphalt is improved, the cleaning effect of the cleaning assembly on the old asphalt is improved through the arrangement of the crushing assembly, meanwhile, the regeneration efficiency of the old asphalt is improved, waste gas generated by regeneration of the old asphalt can be filtered and purified through the arrangement of a smoke filtering assembly, and the environmental protection property is improved.

Description

technical field [0001] The invention relates to the technical field of asphalt processing equipment, in particular to an environmentally friendly old asphalt thermal regeneration equipment and method with a washing function. Background technique [0002] The design service life of asphalt roads is generally 15 to 20 years, which determines the inevitability of asphalt pavement regeneration; the regeneration of asphalt roads has good economics: the recycled materials of asphalt pavements contain recyclable aggregates, old asphalt materials, etc. Raw materials have good economic benefits; asphalt pavement regeneration can save natural resources and reduce pollution: if the recycled asphalt pavement materials are discarded, it will cause great environmental pollution; Possibility to mine quarry and bitumen endlessly. [0003] However, most of the current asphalt recycling equipment lacks an effective cleaning mechanism and cannot clean the old asphalt. The old asphalt is mixed...

Problems solved by technology

[0003] However, most of the current asphalt recycling equipment lacks an effective cleaning mechanism and cannot clean the old asphalt. The old asphalt is mixed with a lot of impurities such as dust or oil stains, which will affect the regeneration effect of the asphalt. At the same time, most of the current asphalt recycling equipment lacks effective waste gas treatment. The mechanism cannot purify the exhaust gas generated by asphalt regeneration, and there are certain defects
