Asphalt concrete pavement comprehensive maintenance equipment for reuse of combustion waste gas

Abstract

The invention discloses comprehensive asphalt concrete pavement maintaining equipment for recycling combustion waste gases. The comprehensive asphalt concrete pavement maintaining equipment comprises a shell, a stirring tank and an asphalt replenishing tank, wherein the stirring tank is fixed inside the shell; the asphalt replenishing tank is fixed above the front part of the shell; the asphalt replenishing tank is covered by a top shell; an exhaust hole is formed in the top surface of the front part of the shell; a first vertical chimney is connected with the exhaust hole; the upper end of the first chimney extends outside the top shell; a sealing door is mounted at the upper end of the first chimney; an interlayer is arranged between the bottom surface of the asphalt replenishing tank and the top surface of the shell; one end of the interlayer is communicated with the lower part of the first chimney; an outlet is formed in the other end of the interlayer; a second vertical chimney is connected outside the outlet; the upper end of the second chimney also extends outside the top shell. According to the structure, the combustion waste gases are adopted to keep the heat of the asphalt replenishing tank, so that an extra heating device is not needed, the equipment structure is greatly simplified, the cost is lowered, the combustion utilization rate is increased, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of asphalt concrete pavement comprehensive maintenance equipment, and in particular relates to a kind of asphalt concrete pavement comprehensive maintenance equipment for recycling waste gas from combustion. Background technique [0002] At present, cast asphalt concrete is mainly constructed on the surface of traffic arteries, bridge decks (especially steel decks), tunnels, airports and cold areas. In order to ensure good performance, this asphalt concrete pavement needs regular maintenance; and as the asphalt ages, it is necessary to heat and melt the original asphalt concrete before adding new asphalt. The existing asphalt concrete pavement comprehensive maintenance equipment mainly includes a casing, a mixing tank fixed in the casing, a stirring shaft passing through the mixing tank, and an asphalt supplement tank fixed above the front part of the casing. A gap is left between the shell and the mixing t...

AI Technical Summary

Problems solved by technology

[0003] Some existing asphalt supplement tanks of asphalt concrete pavement comprehensive maintenance equipment do not have heating devices, and the melted asphalt is easy to solidify during transportation. Once the asphalt solidifies and has poor fluidity, it is very inconvenient to add to the mixing tank

The other part is equipped with a device for heating the asphalt supplement tank, which makes the structure of the whole equipment more complicated and is not conducive to cost control. In order to avoid overheating of the asphalt and affect its performance, the temperature control requirements of the asphalt supplement tank heating device High, more unfavorable for cost control
