Heating and stirring tank for comprehensive pavement maintenance

Abstract

The invention discloses a heating and stirring tank for comprehensive pavement maintenance. The heating and stirring pot for comprehensive pavement maintenance comprises a stirring tank body, a feeding box, a discharging box and an asphalt tank, a heat insulating layer wraps the outer side of the stirring tank body, the stirring tank body is supported by tank support rings, the feeding box is arranged at one end of the stirring tank body and connected with a feed port in the stirring tank body via a feeding flange, the discharging box is arranged at the other end of the stirring tank body, a combustion chamber penetratingly arranged inside the discharging box, a hot air jacket is mounted on the outer side of the combustion chamber, a butting port connected with an air suction pipe is formed in the hot air jacket, the interior of the combustion chamber is connected with a combustor, the other end of the air suction pipe is connected with a deduster, a hot air outlet pipe is connected to the hot air jacket, the other end of the hot air outlet pipe is connected with an air heater, the deduster of a double-layer structure is arranged between the air suction pipe and the air heater, heat conducting oil can be stored in an interlayer of the double-layer structure of the deduster, an oil circulating loop is formed by a heat conducting oil outlet pipe and the heat conducting oil return pipe, an asphalt spraying pipe internally penetrates through the stirring tank body, and asphalt spraying nozzles are distributed on the asphalt spraying pipe.

Description

Technical field: [0001] The invention relates to a heating and stirring tank, which is suitable for heating, stirring and regenerating waste asphalt mixture, and is especially suitable for maintenance and daily repair of asphalt pavement. Background technique: [0002] my country's asphalt pavement not only involves highways, but also national highways, provincial highways, streets, and many country roads. In the daily maintenance process, some places do not pay attention to environmental protection and conservation, and the old asphalt pavement is milled and discarded as waste. The waste asphalt mixture is a kind of pollutant, even if some production enterprises have produced Asphalt mixture reuse equipment, but there are still problems such as large volume, high production cost, and insufficient heat utilization. Invention content: [0003] The task of the present invention is to propose a road surface comprehensive maintenance heating mixing tank with built-in heat...
