Mobile bitumen regenerated heat mixing device

Abstract

The invention discloses movable asphalt regenerative heat mixing equipment which includes a pedestal, a generator set, an organic hot carrier furnace and a mixing pot; the mixing pot includes a feed inlet and a discharge port and also includes a mixing cavity, a heat-conduction oil layer and an insulating layer from the inside to the outside; the mixing pot is communicated with the hot carrier furnace through the heat-conductive oil pipe; a mixing impeller is arranged inside the mixing cavity and the mixing impeller is driven by a speed reduction unit. The invention utilizes the heat-conduction oil to heat the asphalt mixture in the mixing cavity, no open flame appears during the process, also the operation is simple and the temperature is easy to control, the asphalt can not be carbonized or aged during the mixing process and the mixing effect is good, thus being suitable for the regeneration mixing of the old asphalt or the mixing of new asphalt mixtures. The invention is simple in structure, reliable in performance, fast in cold start and low in energy consumption. The equipment has vehicle-borne type movement, is low in manufacturing and using cost, and is suitable for the repair of pits on roads with various grades, particularly the repair of small-area damage on the road surface.

Description

Technical field: [0001] The invention relates to road surface maintenance engineering equipment, in particular to asphalt regeneration hot mixing equipment. Background technique: [0002] Asphalt regeneration mixing equipment mostly adopts drum-type mixing equipment, which is relatively large and needs to be transported to the construction site when it is used. The cost of cold machine start-up is high, and the production capacity of the equipment is large. If it is used for repairing asphalt pavement with a small pit area However, it shows the disadvantages of overuse of materials and high construction cost. Due to the above reasons, such road surface diseases are often not treated in time, which affects the performance and driving safety of the road. Invention content: [0003] The purpose of the present invention is to provide an asphalt regeneration hot mixing equipment with low manufacturing and operating costs and more suitable for small-area road surface disease rep...
