Problems solved by technology

However, the disadvantages of this method are that the mass weighing of the truck scale and the flow adjustment of the regulating valve cannot achieve one-to-one correspondence, the flow control response time is slow, the system adjustment accuracy is low, the equipment occupies a large area, and the investment is high.
If the station control system is not equipped, two weighings are required before loading and after loading, and flow detection and adjustment cannot be performed

Abstract

The invention discloses an asphalt loading metering and adjusting device. One end of a process pipeline is connected with a first flange, one end of a flow adjusting pipeline is connected with the other end of the process pipeline, and a backflow pipeline is connected with the flow adjusting pipeline. One end of a loading crane pipe is connected with the other end of the flow adjusting pipeline, and the other end of the loading crane pipe is inserted into the top of a vehicle; a motor truck scale is connected with a flow controller; an axial flow fan is connected with a pipeline with pumped poisonous volatilization gas, an oil overflow protector is connected with the flow controller, and a static protector is connected with the flow controller; and a loading start-stop button is connected with the flow controller, and an emergency stop button is connected with the flow controller. The invention further provides an asphalt loading metering and adjusting method. The asphalt loading metering and adjusting device and method have the beneficial effects that real-time mass metering and flow adjusting of the loading pipeline can be achieved, the degree of accuracy is high, the operation is stable, the occupied area is small, the integration level is high, and the later maintenance and overhauling are facilitated.

Description

technical field [0001] The invention relates to the technical field of vehicle loading systems, in particular to an asphalt loading metering and adjusting device and a metering and adjusting method. Background technique [0002] In the loading metering station, in order to meet the normal operation of the loading system, it is necessary to perform mass measurement and flow adjustment for high-temperature and high-viscosity liquids. In the past, the mass measurement system and the flow regulation system were mainly set up separately, and the two systems were relatively independent. Among them, the quality measurement system mainly included truck scales and weighing display instruments, and the flow regulation system mainly included upstream cut-off valves and regulating valves. and the data of the flow regulation system are uploaded to the station control system, and the station control system realizes flow detection and regulation. However, the disadvantages of this method ...
