Problems solved by technology

With this method of calibration, since the section of pipeline from the outlet of the mass flowmeter to the calibration tank is not used in normal production, the temperature of the asphalt staying in the pipeline will gradually decrease with the passage of time, and it is often in a semi-solidified state The pipeline is blocked, and the asphalt cannot be sent into the calibration tank when calibration is required. Many users, especially those in northern my country, have to discard it, resulting in that the calibration and production processes cannot be carried out at the same time.

Abstract

A system for proportioning liquid asphalt is composed of high-position tank, check tank, two-way valve connected between outlet of high-position tank and inlet of check tank, asphalt pump, another two-way valve connected between outlet of check tank and tree-way valve connected with asphalt pum, and mass flowmeter connected to asphalt pump. Its technological flow includes such steps as comparing the flow signal from mass flowmeter with the flow setting for regulating the rotation speed of asphalt pump, and calibrating the mass flowmeter by comparing the weighing result of check tank with the result displayed by mass flowmeter.

Description

Technical field: [0001] The invention relates to a process and equipment for producing electrolytic aluminum anodes, in particular to a process and equipment for a liquid asphalt batching system. Background technique: [0002] In the anode production process, for the continuous kneading production line, mass flow meters are used to measure the asphalt flow rate for liquid asphalt batching. After comparing with the set flow rate, the asphalt pump speed is adjusted to realize the quantitative batching of asphalt. In order to ensure the measurement accuracy of the mass flow meter, it is necessary Calibrate the mass flow meter regularly. The traditional calibration technology is: lead the asphalt from the outlet of the mass flowmeter to the calibration tank when necessary, weigh the amount of asphalt within a certain period of time through the calibration tank, and use the weighing results per unit time of the calibration tank to test the mass flowmeter. , Check whether the mea...
