Description

Technical Field

[0001] The utility model relates to the technical field of asphalt modifiers, in particular to a production reactor for a regenerated asphalt modifier. Background Art

[0002] Asphalt modifier refers to natural or synthetic organic or inorganic materials added to asphalt or asphalt mixture, which can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt. The main purpose of adding modifiers to asphalt is to improve the road performance of asphalt mixture at high temperatures, reduce permanent deformation at high temperatures, improve its resistance to rutting, fatigue, aging, and resistance to low-temperature cracking or increase fatigue resistance at low temperatures, so that it meets the requirements of traffic conditions during the design period.

[0003] At present, most reactors use long-axis paddle stirring, which drives the paddle to rotate circumferentially around the long axis through the rotation of the long axis. For example, China Patent Publication No. CN218654429U discloses a modified asphalt modifier production reactor, including a base, the top surface of which is fixedly mounted with two support plates; a reaction tank, the reaction tank is arranged on one side of the two support plates; and a mixing component, the mixing component is arranged inside the reaction tank for mixing. In the above-mentioned public document, the stirring blade is driven to rotate by the rotation of the driving motor driving shaft, and the raw materials are evenly mixed by the rotation of the stirring blade. The reaction tank can be driven to rotate by the rotation of the servo motor driving shaft, and the stirring blade matched with the reaction tank is stirred to improve the mixing efficiency. When the stirring blade stirs the asphalt, the raw materials are heated by the heating plate to avoid asphalt solidification, affect stirring, and improve reaction efficiency. However, when the patent is used, it is not conducive to the layered reaction treatment of the asphalt modifier, so that when the later mixing reaction is completed and needs to be taken out, the reaction tank needs to be shut down and wait, which easily causes a long subsequent processing time, thereby making the processing work efficiency low. To this end, those skilled in the art provide a reactor for producing a regenerated asphalt modifier to solve the problems raised in the above-mentioned background technology. Utility Model Content
