Automatic control system of high-efficiency and energy-saving type asphalt mixture stirring equipment

Abstract

The invention discloses an automatic control system of high-efficiency and energy-saving type asphalt mixture stirring equipment. The automatic control system automatically detects the asphalt mixture stirring equipment through a detecting unit. The detecting unit comprises detectors (a current detector, a voltage detector and the like), sensors (a pressure sensor, a temperature sensor, a rotating speed sensor, a carbon monoxide sensor, a nitric oxide sensor, a sulfide sensor, an oxygen sensor, a grayscale sensor, a weighing sensor, a position sensor, a combustible gas sensor and the like), and a measurement instrument (a viscosity measurement instrument). A combustor, a monitoring frequency converter, an induced draft fan and a drying drum are arranged inside the asphalt mixture stirring equipment. According to the asphalt mixture stirring plant control system, the automatic control system is connected with the drying drum through the combustor, the monitoring frequency converter and the induced draft fan. The automatic control system has the beneficial effects that a self-detecting function is achieved, precognition and early-stage judgment can be achieved, a prevention effect is achieved, the heat efficiency of the drying drum is automatically adjusted, the electric power of the whole machine is automatically adjusted, power consumption is reduced, the structure is simple, and practicality is high.

Description

technical field [0001] The invention relates to the field of asphalt mixture mixing equipment, in particular to a high-efficiency and energy-saving asphalt mixture mixing plant control system. Background technique [0002] In recent years, with the development of highway construction, on the one hand, the old asphalt mixture produced by major and medium highway repairs has increased year by year, resulting in a large amount of solid waste; More production of new asphalt and mining of stone will bring huge waste of resources to the society. Asphalt mixture plant heat recycling technology can process and recycle waste asphalt mixture. It is currently the most widely used asphalt mixture regeneration method in the industry. It avoids new resource consumption and promotes the recycling of existing resources. At present, there is no related technology for the control system of high-efficiency and energy-saving asphalt mixing plant. [0003] Therefore, it is necessary to propose...
