Microwave heating device for fast repairing asphalt pavement

Abstract

The invention discloses a microwave heating device for fast repairing an asphalt pavement. A furnace body bracket is connected with a microwave furnace body component, a microwave generator is installed in an inner cavity of the microwave furnace body component, the left side of the furnace body bracket is connected with a front part platform device, a discharging device and a control cabinet, a guide angle steel and a tail bracket are connected to the discharging device, the guide angle steel is connected with an operation platform through a connecting rod piece, a heat preservation materialstoring device is connected below the operation platform, a motor and a reducer are in rolling connection with a synchronizer through a belt or a chain, a plurality of roll wheels are distributed on a motive track at intervals, a closed chain is sleeved on each roll wheel, a lifting device is installed at the upper end of the motive track, the lower end of the left side of the furnace body bracket is connected with supporting legs, and a ventilation opening is arranged at the upper end of the microwave furnace body component, therefore, the invention has the advantages of enhancing the pavement repairing speed, heating quantitative mixture at any time and anywhere according to the needs, removing a long distance transportation link, improving the aggregate performance, overcoming the asphalt ageing, realizing environmental protection, energy saving and equipment automation and lowering the labor intensity and the pavement repairing cost and is suitable for fast repairing the asphalt pavement.

Description

technical field [0001] The invention relates to a device for repairing asphalt pavement, in particular to a microwave heating device for rapidly repairing asphalt pavement. technical background [0002] At present, the traditional road surface pothole repair method is time-consuming and laborious, the repair quality is poor, the maintenance cost is high, and the road surface repair is not timely, and the potholes are often larger and larger, which is difficult to meet the driving requirements. Generally, the asphalt mixture used for repairing asphalt pavement potholes is prepared by heating in a fixed mixing building or on-site with an open flame. The vehicle is transported to the repair site, and the asphalt and aggregate are heated with heat energy. The heating method in the prior art is slow in heat transfer. , the heating time is long, and the heat loss of the mixture is fast during transportation, especially in winter. If the temperature is too high during heating, the ...

[0002] At present, the traditional road surface pothole repair method is time-consuming and laborious, the repair quality is poor, the maintenance cost is high, the road surface repair is not timely, the potholes are often bigger and bigger, and it is difficult to meet the driving requirements

Generally, the asphalt mixture used for repairing asphalt pavement potholes is prepared by heating in a fixed mixing building or on-site with an open flame. The vehicle is transported to the repair site, and the asphalt and aggregate are heated with heat energy. The heating method in the prior art is slow in heat transfer. , the heating time is long, and the heat loss of the mixture is fast during transportation, especially in winter. If the temperature is too high during heating, the asphalt will be seriously aged. In addition, a small amount of heated mixture cannot guarantee the rolling required for construction after long-distance transportation. Defects such as high pressure temperature, flue gas generated by open flame heating on site affect air quality, etc.
