Asphalt high-efficiency stirring device capable of preventing adhesion on inner wall

Abstract

The invention relates to the field of asphalt production, and particularly relates to an asphalt high-efficiency stirring device capable of preventing adhesion on an inner wall. The device comprises a device main body and a heating wall; a vibrating wall is fixedly arranged in the device main body; the inner side of the vibration wall is fixedly provided with a vibration guide wall; and the inner side of the vibration guide wall is fixedly provided with a heating wall. The heating wall is arranged in a mode of a bent curve, so that the contact area between asphalt and the heating wall is larger and heating efficiency is higher. When a rotating piece rotates to drive the asphalt to move upwards, the asphalt can roll and overflow from the edge of the rotating piece, flows downwards from the gap between the heating wall and the rotating piece for carrying out heating at a fixed time, then falls on to the bottom end, and then is driven upwards by the rotating piece for forming a circulation, so that the heating time of the asphalt is uniformly controlled. Inclined blocks are arranged inside stirring wheels at the edge of the rotating piece, and when stirring rods on the inclined blocks rotate around the inclined blocks, the stirring rods at the upper end are retracted and the stirring rods at the lower end extend outwards, so that when the asphalt overflows from the edge of the rotating piece, the stirring wheels can be driven to rotate to further stir the asphalt on the rotating piece.

Description

technical field [0001] The invention relates to the field of asphalt production, in particular to a high-efficiency asphalt stirring and anti-sticking device on the inner wall. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. The appearance is liquid, semi-solid or solid. It is widely used in building waterproofing, underground structure anti-corrosion, road laying and other fields. [0003] In order to make the asphalt reach the required strength in various fields, it is necessary to add various admixtures to it for heating and stirring, but the existing asphalt mixing device is easy to heat the asphalt unevenly, so that part of the asphalt is heated for too long and part of it is overheated. It is short and the mixing with the solvent is not uniform enough. At the same time, part of the asphalt is easy to stick to the inner wall after the mixing is completed, wh...

[0003] In order to make the asphalt reach the required strength in various fields, it is necessary to add various admixtures to it for heating and stirring, but the existing asphalt mixing device is easy to heat the asphalt unevenly, so that part of the asphalt is heated for too long and part of it is overheated. It is short and the mixture with the solvent is not uniform enough. At the same time, after the mixing is completed, some asphalt is easy to stick to the inner wall, which reduces the heating efficiency and requires frequent cleaning.
