Recycled asphalt mixture continuous heating control system

Abstract

Provided is a recycled asphalt mixture continuous heating control system. The system comprises a first heating roller, a second heating roller, a third heating roller and a controller. The three heating rollers are butted together from up to down. The three heating rollers are arranged to be tilted and S-shaped. A feed inlet is arranged at the front end of the first heating roller and the front end of the first heating roller is connected with an induced draft fan. A crushing mechanism is arranged in the second heating roller, and the crushing mechanism is cutting lines arranged at intervals in the roller body. A feed outlet is arranged at the tail end of the third heating roller and the tail end of the third heating roller is connected with an air-heater. Each heating roller is respectively connected with a set of a rotation mechanism. An infrared temperature sensor is arranged at the outer side of each heating roller. The induced draught fan, the air-heater, the three sets of rotation mechanisms and the three temperature sensors are connected with the controller. The heading direction of materials in the three heating rollers is opposite to the heading direction of heat energy. The system is adapted to different states of heating processes of recycled asphalt mixture, solves the problems of bonding and agglomeration, is adapted to drying technological parameters of recycled asphalt mixture at different states, reduces energy consumption and improves heat transfer effects.

Description

technical field [0001] The invention relates to a control system for heating when waste asphalt mixture is recycled, and belongs to the technical field of heating control of recycled asphalt mixture. Background technique [0002] A large amount of waste asphalt mixture will be produced in the process of road renovation. The waste asphalt mixture contains aged asphalt, gravel and sand. The reuse value of the waste asphalt mixture is still high after regeneration. With the strengthening of people's awareness of environmental protection and effective use of resources, governments of various countries have imposed legislation on the discharge of solid waste, and waste asphalt mixture as solid waste cannot be piled up or discarded at will. Therefore, the recycling technology of old asphalt pavement materials has become a hot topic worldwide. The recycling and reuse of old asphalt materials can achieve the goals of saving resources, reducing environmental pollution and public nuis...
