Fuel gas and electricity hybrid heated asphalt mixture sliding type stirring device and working process thereof

Abstract

The invention relates to a fuel gas and electricity hybrid heated asphalt mixture sliding type stirring device and a working process thereof. The stirring device disclosed by the invention is characterized in that (1) an electric heater for conductive preheating is adopted at the bottom of a cylinder body, so that asphalt at the bottom of the cylinder body is not stuck to the cylinder body; meanwhile, an infrared heater is adopted on the top of the cylinder body, and the heating effect of the asphalt is ensured by using the permeability of the infrared heater; (2) the electric heater is flat and is small in size and suitable for being installed at the bottom of the cylinder body, and the stirring device adopts a nested installation manner, so that the whole structure is compact and the overall installation of the stirring device is not affected; (3) the lower part of the cylinder body can ascend and descend, so that the asphalt residue can be conveniently cleaned as long as the bottom of the cylinder body declines.

Description

technical field [0001] The invention relates to a stirring device for an asphalt pavement in-situ thermal regeneration remixing machine and its working process, more precisely, an asphalt mixture stirring device heated by gas and electric mixing and its working process. Background technique [0002] Hot-in-place regeneration is a preventive maintenance technology, which is to use special hot-in-place regeneration equipment to heat and mill the asphalt pavement, add a certain amount of new asphalt, new asphalt mixture, regeneration agent, etc. Mixing, paving, rolling and other processes, one-time realization of the old asphalt concrete pavement regeneration technology within a certain depth of the surface. This technology has been widely promoted and applied in China because of its low-carbon environmental protection, high efficiency and energy saving, fast construction speed, low cost, no closed traffic during operation, and 100% on-site reuse of old asphalt pavement materia...

AI Technical Summary

Problems solved by technology

[0006]1. Diesel or kerosene is used as fuel to generate high temperature, and the hot air is sent to the heating box through the fan to heat the stirring device. The energy consumption is very high and the economy is relatively high. Poor, greatly increase the construction cost

[0007]2. The hot air circulation heating penetration ability is poor, which may easily cause insufficient heating of the asphalt mixture and affect the paving quality of the asphalt mixture;

[0008]3. Under low temperature construction conditions, the temperature of the asphalt mixture in the mixing tank will drop too fast, and it will easily adhere to the inner wall of the mixing tank to form compaction, which is difficult to Clean up, affect reuse;
