Mixing device used on asphalt road surface site heat regeneration compound mixer

Abstract

The invention relates to a mixing device used on an asphalt road surface site heat regeneration compound mixer, which comprises a hydraulic motor, a hot air heating furnace, a gas circuit interface, a mixing box body, a mixture stirrer, a control device and a temperature detector; the mixing box body comprises two circular arc-shaped side wall plates of the box body, two end surface plates of thebox body, a top plate of the box body and a support of the box body; a feed opening and a hot air interface are arranged on the top plate of the box body; the hot air interface is connected with the hot air heating furnace; the hot air heating furnace is hinged with a base support; the feed opening is connected with a pneumatic gate valve; a discharge port is arranged at a joint between the bottoms of the circular arc-shaped side wall plates of the box body; the discharge port is connected with a pneumatic arc-shaped swing valve; the pneumatic arc-shaped swing valve and the pneumatic gate valve are connected with the control device; and the temperature detector is arranged on the hot air heating furnace. The mixing device used on the asphalt road surface site heat regeneration compound mixer can realize a heating while stirring function in the closed mixing box body, the feeding, the discharge and the temperature can be automatically controlled, so that the regenerated mixture is moreuniform, the requirements of a construction process are met, and the road surface pavement quality is improved.

Description

technical field [0001] The invention belongs to the technical field of hot-in-place regeneration of asphalt pavement, and in particular relates to a mixing device used in a remixer for hot-in-place regeneration of asphalt pavement. Background technique [0002] At present, the regeneration technology and regeneration method of asphalt pavement have been widely recognized and applied, and the regeneration equipment and process using this regeneration technology and method are also constantly developing and improving. The so-called "regeneration of asphalt pavement" is to recycle and process the asphalt mixture on the used and damaged old asphalt pavement, and continue to use it in road repair or paving projects. [0003] China's highways have gradually transitioned from the era of construction to the era of maintenance. The content and workload of highway maintenance have increased rapidly. Every year, more than 10% of the road surface needs to be repaired and maintained. The...

Problems solved by technology

[0006] 1) During construction in the north, especially in winter, the temperature of the asphalt mixture entering the mixing box drops too fast, which affects the mixing quality and causes the asphalt mixture to adhere too much to the inner wall of the mixing box. Clean up High difficulty;

[0007] 2) The circulation of a single material rolls up and down, making the mixing of the asphalt mixture uneven, especially if the asphalt mixture is mixed with blocky old materials, this mixing form and the reason of temperature will not be able to decompose the block old material
