Foamed asphalt stone warm mixing addition system

Abstract

The invention relates to an asphalt stone production technology, and especially relates to a foamed asphalt stone warm mixing addition system. The system comprises a bunker, a device rack, an elevator arranged at one side of the device rack and connected with the bunker, a heating tube barrel arranged at the top of the device rack, connected with the outlet of the elevator and having an obliquely arranged outlet, a blanking cabin connected with the outlet of the outlet of the heating tube barrel, and a mixing cylinder arranged at the outlet of the blanking cabin, one side of the outlet at the lower end of the heating tube barrel is provided with a fuel bocca, the inlet at the higher end of the heating tube barrel is provided with a fan, rotary overturning teeth are arranged in the heating tube barrel, the inside of the upper end of the mixing cylinder is connected with an asphalt foaming device, rotary stirring blades are arranged in the mixing cylinder, and the lower end of the mixing cylinder is provided with a material outlet. Regenerated asphalt stones are heated in the heating tube barrel, so molten regenerated asphalt stones enter the mixing cylinder, and combine with foamed asphalt generated in the asphalt foaming device, thereby the properties of the regenerated asphalt stones are improved, and the regenerated asphalt stones can be used in pavement surface layers to realize good laying effect of the road pavement.

Description

technical field [0001] The invention relates to asphalt aggregate production process equipment, in particular to a foamed asphalt aggregate warm mixing adding system. 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 foamed asphalt stone warm mixing adding system. [0004] The present invention is achieved through the following technical solutions: [0005] A warm mixing and adding system for foamed 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 installed o...
