Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of asphalt production, and particularly relates to a stirring device for asphalt production. BACKGROUND

[0002] Asphalt is a waterproof, moisture-proof and corrosion-proof organic cementing material, which can be mainly divided into coal tar pitch, petroleum pitch and natural asphalt. At present, asphalt is mainly used in the production of coating, plastic, rubber and other industries and pavement.

[0003] Asphalt is also used in engineering production. Asphalt concrete made of asphalt and sandstone is often used for ground laying. In the production of asphalt concrete, a stirring device is needed to mix asphalt and sandstone. The commonly used stirring device in engineering is to mix asphalt and sandstone and put them into a stirring tank, which is driven by a motor to stir, and a clear fire is used to heat the inside of the tank to achieve the effect of melting asphalt. Due to the use of open flame heating, the asphalt in the tank is not uniformly heated. The asphalt near the flame will be overheated and aged, while the asphalt away from the flame will not be uniformly heated and melted, which is difficult to combine with sandstone. At the same time, the currently used stirring rod is single-shaft type, which causes the asphalt far from the shaft center to be not stirred uniformly, which seriously affects the quality of asphalt concrete.
