Problems solved by technology

Concentric ring steps with different diameters and different axial heights are processed on the conical inner surface of the spreading disc of this invention. There is a gap between the spreading disc and the lower end of the retaining ring, but this invention cannot prevent asphalt deposition It sticks to the bottom of the tank, and it is not conducive to the efficient mixing of asphalt. It cannot avoid the phenomenon of sedimentation and stratification. It cannot realize the fixed ratio mixing of asphalt and mineral materials, and cannot realize the synchronization of mixing and feeding.

Abstract

The invention relates to the technical field of road petroleum asphalt mixing processing, in particular to a road petroleum asphalt mixture gradation adjustment device and method. The road petroleum asphalt mixture gradation adjustment device comprises a mixing tank, a feeding device, a motor, a shaft rod, a compression bolt, a mixing device, a compression spring, a material blocking assembly, a fixed ratio assembly, an arc-shaped elastic telescopic part and a feeding impeller; the ore material flow can be controlled according to the asphalt flow; stirring and feeding can be synchronously carried out through the feeding impeller; asphalt and ore materials can be prevented from being deposited and adhered to the bottom of the mixing tank through the mixing device, so that the asphalt and the ore materials in the mixing tank can be fully mixed, and meanwhile, the phenomenon that the asphalt and the ore materials are deposited and layered according to the density can be avoided; the asphalt and the ore materials can be injected into the mixing tank separately, thereby facilitating the ore materials with different densities or different particle sizes to be put into the mixing tank insequence, so that when the ore materials are not fully mixed, the autorotation speed of the spiral stirring impeller is increased, and the mixing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of road petroleum asphalt mixing processing, in particular to a road petroleum asphalt mixture gradation debugging device and method. Background technique [0002] For example, the patent application number is CN200710017861.0, a kind of asphalt and rubber powder mixer for rubber asphalt production equipment.
