Asphalt weighing, proportioning and conveying system

Abstract

The invention relates to an asphalt weighing and batching conveying system, which includes a storage bin (1), a feeder (2) is arranged at the bottom discharge port of the storage bin (1), and a feeding device (2) A weighing hopper (3) is set at the bottom outlet, and the asphalt material weighed by the weighing hopper (3) enters the air mixing pneumatic sending tank (4) connected to the bottom outlet of the weighing hopper (3). The outlet of the tank (4) is connected to the buffer bucket (6) through the delivery pipeline (5), and the outlet of the buffer bucket (6) is connected to the terminal receiver (9). A silo ventilation filter (10) is arranged on the discharge port, and the asphalt material passed through the filter is finally transported to the silo. The invention uses the airflow to transport materials in the pipeline through the pneumatic conveying device, which can carry out long-distance transportation. At the same time, it is equipped with a high-precision air-activated feeder to realize the measurement accuracy of asphalt materials and ensure the continuity of production, thereby greatly improving work efficiency.

Description

technical field [0001] The invention belongs to the field of asphalt mixture conveying equipment, in particular to an asphalt weighing and batching conveying system. Background technique [0002] As the competition in the road construction market continues to increase, construction units such as highways and municipalities have continuously increased their requirements for flexible control of the production process of asphalt mixing equipment. At the same time, energy conservation and environmental protection have received increasing attention. higher requirements. [0003] At present, in the asphalt supply process, the relatively common problem is that the control of asphalt weighing is not accurate, and the finished materials produced cannot meet the construction requirements; when the asphalt pump fails, all the asphalt in the pipeline needs to be emptied. Asphalt can effectively dismantle asphalt pumps with fault points, which will virtually increase the workload of mix...

Problems solved by technology

[0003] At present, in the asphalt supply process, the relatively common problem is that the control of asphalt weighing is not accurate, and the finished materials produced cannot meet the construction requirements; when the asphalt pump fails, all the asphalt in the pipeline needs to be emptied. Asphalt can effectively disassemble the asphalt pump with fault points, which will increase the workload of the operator of the mixing plant virtually.

If the metering accuracy and production continuity of the asphalt supply system cannot be effectively resolved, the work of the overall equipment cannot be guaranteed
