Thermal regeneration asphalt stone material addition system

Abstract

The present invention relates to an asphalt stone material production process, particularly to a thermal regeneration asphalt stone material addition system, which comprises a material bin, an equipment rack, a lifter arranged on one side of the equipment rack and connected with the material bin, a heating pipe barrel arranged on the top end of the equipment rack, connected with the lifer outlet and with an obliquely-arranged outlet, a material discharge bin connected with the heating pipe barrel outlet, and a stirring cylinder arranged on the material discharge bin outlet, wherein a fuel crater is arranged on one side of the lower end outlet of the heating pipe barrel, the high end inlet of the heating pipe barrel is provided with an induced fan, rotation type turn teeth are arranged inside the heating pipe barrel, a liquid state asphalt spraying nozzle is connected on the internal of the upper end of the stirring cylinder, rotation stirring blades are arranged inside the stirring cylinder, and the lower end of the stirring cylinder is provided with a material outlet. According to the present invention, the regeneration asphalt stone material is heated in the heating pipe barrel, such that the regeneration asphalt stone material melts and then enters the stirring cylinder and then is sprayed and stirred so as to improve the nature of the regeneration asphalt stone material, and the regeneration asphalt stone material can be used for the road surface layer, and the road surface paving effect is good.

Description

technical field [0001] The invention relates to a production process of asphalt aggregates, in particular to a system for adding thermally recycled asphalt aggregates. Background technique [0002] Asphalt aggregates are used for road pavement by spraying asphalt on them. Existing asphalt aggregates are generally crushed and used as pavement bases in the recycling process. However, the pulverized asphalt aggregates lack the viscosity of asphalt, which makes the road pavement effect poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a system for adding thermally regenerated asphalt stones. [0004] The present invention is achieved through the following technical solutions: [0005] A system for adding heat recycled asphalt stones, including a silo, an equipment frame, a hoist connected to the silo on one side of the equipment frame, and a heating pipe bucket arra...
