A kind of asphalt pavement hot-in-place recycling machine for recycling asphalt smoke and dust

Abstract

The invention discloses an in-situ heat regeneration machine for asphalt pavement, which includes a new material adding device, a recycled material collecting device, a layered heating device for recycled materials, and a regenerated waste smoke and dust recycling device; the new material adding device and The reclaimed material collection device is used to provide new asphalt mixture and pavement reclaimed material for the regenerated material layered heating device respectively; Heating auger, the outer side of the heating mixing tank is provided with a heating plate, the outlet of the upper heating mixing tank is connected with the feeding port of the heating mixing tank adjacent to the lower layer; the regenerated waste smoke recycling device includes a burner, and the The regenerated material layered heating device is connected to the burner through the hot air conveying pipe, and the burner is connected to the road surface heating plate through the hot air conveying pipe. The invention improves the final paving and rolling temperature, and at the same time changes the problem of unorganized emission of waste asphalt smoke and dust in traditional regeneration units.

Description

technical field [0001] The invention relates to an on-site thermal regeneration machine for asphalt pavement, in particular to an in-situ thermal regeneration machine for asphalt pavement recycling. Background technique [0002] At present, the in-situ recycling machines produced by various brand manufacturers at home and abroad work on the principle of using the recycled materials heated by the original road surface to use the horizontal mixing cylinder that comes with the recycling unit to mix and spread the raked recycled materials. Due to the heating of the original road surface The heating capacity of the machine is limited, and the paving temperature of the general pavement regeneration mixing is 120--130 ℃, which is lower than the national standard paving temperature of asphalt mixture 140-160 ℃. Moreover, the existing in-situ recycling machine has the problem of unorganized emission of waste asphalt smoke and dust in the working process, which wastes energy and pollu...
