AI Technical Summary
During the conveying process, rubber granules are prone to static electricity accumulation, which can lead to adhesion and blockage. In particular, in the vertical lifting section, the gravity of the material affects the particle arrangement and collapse, increasing the risk of blockage.
The first vibration motor drives the conveying pipe to generate high-frequency vibration. Combined with the design of spiral guide vanes and elastic corrugated pipe, it breaks electrostatic adsorption and uses pneumatic conveying to make the particles rise along the spiral path to prevent local accumulation.
It effectively avoids the adhesion and blockage of rubber particles, ensures smooth conveying, reduces clumping, and improves conveying efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of material transportation technology, and more specifically, to a rubber granule lifting device. Background Technology
[0002] Currently, in the preparation process of asphalt modifiers, it is necessary to use a lifting device to transport rubber particles to the feed inlet at the top of the mixing tank. Although many optimizations have been made in terms of conveying efficiency, there are still some defects in practical applications.
[0003] First, rubber granules are insulating, and static electricity is easily generated during transportation due to friction with the pipe wall or collisions between granules. Because rubber itself has poor conductivity, the charge is difficult to dissipate through grounding, leading to static electricity accumulation. When the static voltage reaches a certain threshold, the adsorption force between particles increases, causing adhesion and forming clumps or blockages. Second, especially in the vertical lifting section, the gravity of the material affects the arrangement and collapse of particles, further increasing the risk of particle adhesion and thus exacerbating the possibility of blockages.
[0004] Therefore, how to effectively solve the problem of rubber particles sticking and clogging during transportation is an urgent technical issue that needs to be addressed. Utility Model Content
