Intermittent forced type asphalt mixture metering method
The invention discloses an intermittent forced type asphalt mixture metering method. Aggregate is weighed with a secondary weighing and impulse correction combined method, secondary weighing comprises primary rough weighing and secondary fine weighing, a discharging bin door is completely open during rough weighing, when the aggregate is weighed to be 80% of a set value, the bin door is half-opened, and when the fed aggregate reaches the sum of an aggregate impulse correction value and the difference between the set value and a fall compensation value during fine weighing, the discharging bin door is closed; a primary weighing method is adopted for mineral powder, the discharging bin door is completely opened during weighing, and when the fed material reaches the difference between the set value and the fall compensation value, the discharging bin door is closed; asphalt is weighed with a primary weighing and impulse correction combined method, the impulse correction value of the asphalt is adjusted according to the difference between the set total aggregate sum and the actual feeding weight, and when the fed asphalt reaches the sum of the asphalt impulse correction value and the difference between the set value and the fall compensation value, an asphalt pump is shut down. With the adoption of the method, the accuracy of the ratio of the aggregate to the asphalt of an asphalt mixture can be increased.
