An integrated reactor for asphalt modification

Abstract

The invention discloses an asphalt-modified integrated reactor. The reactor comprises a vertical casing, a stirring mechanism for stirring to mix asphalt and a modifier, a heat exchange reaction mechanism for a heating synthesis reaction of the mixed asphalt and modifier, a thermal insulation mechanism for keeping the temperature of the asphalt and the modifier after the synthesis reaction and keeping a viscous state and a slag removal mechanism for removal of waste residues in the asphalt and modifier synthesis reaction. The reactor can be conveniently installed, has high safety, realizes continuous production through material potential difference, is free of an asphalt pump, prevents asphalt pump wear, obstruction and blocking accidents caused by slag, improves production efficiency, reduces a heat radiation area through the thermal insulation mechanism and saves energy. The slag removal mechanism has a slag removal function and guarantees normal running of the whole reactor.

Description

Technical field [0001] The invention relates to an integrated reactor, in particular to an integrated reactor for asphalt modification. Background technique [0002] The structure of the traditional asphalt modification reactor is similar to that of the chemical reactor, but it has the disadvantages of slow heating of materials, low productivity, and heavy environmental pollution due to open feeding and heating. [0003] In order to meet the needs of the modern highway asphalt market, in recent years, domestic research results and patent disclosures in this aspect of asphalt modification reactors have continued; for example, Chinese Patent Application No. CN201020163780.9 discloses a rubber asphalt heating and mixing device, which solves the problem of rubber asphalt heating and mixing. However, the external mixing tank is required, and the steel wire slag in the rubber powder modifier cannot be eliminated. The external filter is required, but the external asphalt pump is still vul...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the existing existing asphalt modification reaction equipment in the prior art, which cannot mix materials and filter residues, needs to be equipped with an asphalt pump and is vulnerable, some parts have large heat dissipation surface area, poor heat preservation and energy saving effect, and some devices are large in volume. For the above deficiencies such as difficulty in installation at an angle and poor safety, a kind of asphalt modification integrated reactor is provided. The reactor is set up vertically and relies on material level difference to realize continuous production, so asphalt pumps are not required, and asphalt pumps are saved. Accidents caused by material wear, blockage, and damage are improved, production efficiency is improved, heat dissipation area is reduced, energy is saved, and slag removal function is provided at the same time
