Technical Field
The utility model relates to a pitch measurement and spray discharge apparatus are applied to the bituminous mixture agitated vessel field in the road building machinery.
Background
In the field of asphalt mixing equipment, the metering and discharging modes of asphalt generally have two technical routes: firstly, the asphalt is automatically discharged after being metered, and automatically flows into a stirring cylinder to participate in stirring of the mixture under the influence of gravity (the mode is called self-discharging mode for short later); secondly, after the asphalt is measured, the asphalt in the measuring hopper is pumped out by an asphalt pump, and then the asphalt is sprayed into the stirring cylinder through a pipeline to participate in the stirring of the mixture (the mode is called spraying mode for short). The two modes have the advantages and the disadvantages respectively, the first mode has the advantage of low manufacturing cost, and the disadvantages that the asphalt cannot be uniformly added into the aggregate to participate in stirring, so that the stirring time of the mixture can be prolonged, the stirring uniformity is influenced, and the quality of finished products is further influenced. The second mode has the advantage that the asphalt can uniformly participate in the stirring with the aggregate and the mineral powder, but the metering precision can generate larger deviation in the asphalt metering process. The inaccurate asphalt measurement not only affects the financial statement of the material, but also affects the quality of the asphalt mixture finished product. In conclusion, both asphalt metering and discharging modes ultimately affect the quality of the finished product.
