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 is not conducive to the efficient mixing of asphalt. It is unavoidable that it is a phenomenon of sedimentation and stratification.

Abstract

The invention relates to the technical field of road petroleum asphalt mixing and processing, more specifically, a road petroleum asphalt mixture device and method, including a mixing tank, a feeding device, a motor, a shaft, a compression bolt, a mixing device and a compression spring. The feeding device is fixedly connected to the upper end of the mixing tank, the motor is fixedly connected to the feeding device, the shaft rod is fixedly connected to the transmission receiving shaft of the motor through a coupling, and the pressing bolts are connected through thread fit. On the shaft, the mixing device is slidably connected to the lower end of the shaft, the compression spring is sleeved on the shaft, the compression spring is located between the compression bolt and the mixing device, and the mixing device has clearance fit in the mixing tank. The invention can prevent asphalt and mineral material from depositing and sticking to the bottom of the mixing tank, can fully mix the asphalt and mineral material in the mixing tank, and can avoid deposition and stratification of the asphalt and mineral material according to density.

Description
