Description

Low temperature asphalt is portable asphalt mixing plant for stirring

Technical Field

The invention relates to the technical field of asphalt processing equipment, in particular to a movable asphalt mixing station for low-temperature asphalt mixing.

Background

In the existing asphalt stirring equipment, the high-temperature stirring is generally carried out, namely, the temperature of asphalt is 150-170 ℃, harmful gas in the asphalt is easy to volatilize under the temperature stirring, so that the surrounding air environment is influenced, therefore, in order to improve the environmental protection effect, the existing cold-stirring asphalt can be used by only stirring the asphalt heated to 60 ℃, however, the asphalt can not be basically mixed with water liquid, the proportion control requirement is high, in the existing high-temperature asphalt stirring equipment, the asphalt is exposed to the outside for stirring, and when the external air humidity is too high, water drops are formed on the surface of a stirring material or on the inner wall of a stirring tank, so that the water liquid is easy to mix in the stirring equipment, and the stirring and mixing effects are influenced;

Meanwhile, the stirred stones enter the stirring barrel directly after entering from the feeding hopper for stirring, the amount of the stones cannot be known from the feeding hopper, the stones are generally weighed outside before feeding and then poured into the feeding hopper, however, after weighing, part of the stones possibly fall from the discharging tray into the discharging tray after being poured into the feeding hopper, so that the actual feeding amount of the stones is influenced, errors are generated, the subsequent stirring proportion is influenced, and the accuracy of the subsequent discharging amount is influenced to a certain extent;

The weighing is carried out before feeding, so that the feeding procedure is increased, and the effect is not ideal;

Likewise, in the existing asphalt stirring equipment, asphalt for stirring is directly poured into the stirring tank from the feeding hole, so that feeding uniformity is poor, a subsequent stirring effect is affected, feeding quantity is uncontrollable, the asphalt can be poured into the discharging tray after corresponding weight is weighed out, the asphalt is recessed into the stirring tank through the discharging tray, and in the whole process, part of asphalt often leaks from the discharging tray when pouring, so that accuracy of feeding quantity is affected.

And the weighing step is needed before feeding, so that the preamble process of feeding is increased, and the effect is not ideal.
