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:
The present invention relates to flow process and equipment that a kind of electrolytic aluminium anode is produced, particularly relate to a kind of liquid asphalt proportioning system flow and equipment.
Background technology:
In the anode production process, pinch production line for mixing continuously, the eu-bitumen batching mass flowmeter metering pitch flows that adopt more, thereby realize the bituminous quantitative ingredient through adjusting the bitumenpump rotating speed with the setting throughput ratio, for guaranteeing the Measuring Precision of mass flowmeter, must regularly carry out verification to mass flowmeter.The tradition calibration technology is: when needing the pitch of mass flowmeter outlet is guided to the verification groove, through the pitch amount in the verification groove weighing certain hour, utilize interior weighing result of verification groove unit time that mass flowmeter is tested, whether the Measuring Precision of the under meter of checking on the quality satisfies service requirements.The Measuring Precision of verification groove is then carried out verification through counterweight.Adopt this mode verification, owing to export to a segment pipe of verification groove from mass flowmeter, do not use during ordinary production, rest on ducted pitch As time goes on, temperature will reduce gradually, usually be in half curdled appearance and cause line clogging, and pitch can't be sent into the verification groove when the needs verification, the many users especially user of northern China have to discard mostly, cause verification and production process not to carry out simultaneously.
Summary of the invention:
The objective of the invention is: improve traditional asphalt batching flow process, eliminate the factor that causes line clogging, make Production Flow Chart unblocked, guarantee to carry out at any time in the production process Measuring Precision verification of mass flowmeter, thereby guarantee the accuracy of pitch batching.
When the present invention is achieved in that ordinary production, pitch in the pitch header tank (4) is through two-port valve (5), verification groove (3), two-port valve (7), T-valve (6), two-port valve (8), utilize bitumenpump (2) to extract out and deliver in the kneading machine through mass flowmeter (1), Controlling System compares detected flow signal of mass flowmeter (1) and setting flow, if comparative result is variant, the rotating speed of in time adjusting bitumenpump automatically is consistent with mass flowmeter (1) detected result with the pitch flow of guaranteeing to set; At this moment, verification groove (3) only conduct is carried the bituminous passage, and the pitch flow is not detected; When mass flowmeter (1) is carried out verification, pitch in the pitch header tank (4) enters verification groove (3) through two-port valve (5), earlier the pitch amount in the verification groove (3) is detected, pitch is by two-port valve (7), T-valve (6), bitumenpump (2), two-port valve (8) then, through delivering in the kneading machine behind mass flowmeter (1) the detection flow, the weighing result in verification groove (3) unit time and the detection flow of mass flowmeter (1) are compared check, thereby check whether the Measuring Precision of confirming mass flowmeter (1) satisfies service requirements.
The present invention constitutes like this: it comprises header tank (4), between the outlet that two-port valve (5) is connected header tank (4) and the import of verification groove (3), between two-port valve (7) outlet that is connected verification groove (3) and the T-valve (6), T-valve (6) is connected with bitumenpump (2), bitumenpump (2) is connected with mass flowmeter (1), more than connect to be pipe connection
Bitumenpump (2) is two and is connected in parallel; Import and export at bitumenpump (2) is connected with two-port valve (8); Header tank (4), verification groove (3) and T-valve (6) all pass through pipe connection with pitch storage tank.
The invention has the beneficial effects as follows: eliminated the reason that the pipeline generation is stopped up in the traditional asphalt batching flow process, made Production Flow Chart unblocked; Can guarantee to carry out in process of production the Measuring Precision verification of mass flowmeter, thereby guarantee the accuracy of pitch batching.

Embodiment:
Embodiments of the invention: according to bituminous feed flow and pressure requirement, design header tank 4, verification groove 3, select the specification of bitumenpump, various valve and pipeline, then they are coupled together in the following order: the outlet of header tank 4 is connected with an end of two-port valve 5, between the import of the other end of two-port valve 5 and verification groove 3, the outlet of verification groove 3 is connected with an end of two-port valve 7, the other end of two-port valve 7 is connected with an end of T-valve 6; The import and export of two bitumenpumps 2 all connects two-port valve 8 back parallel connections and is connected the pipeline of mass flowmeter 1 and kneading machine with T-valve 6 with mass flowmeter 1; The overflow port and the T-valve 6 of the overflow port of header tank 4, following row's mouth, verification groove 3 all pass through pipe connection with pitch storage tank.
During ordinary production, pitch in the pitch header tank 4 is through two-port valve 5, verification groove 3, two-port valve (7), T-valve 6, two-port valve 8, utilize bitumenpump 2 to extract out and deliver in the kneading machine through mass flowmeter 1, Controlling System compares mass flowmeter 1 detected flow signal and setting flow, if comparative result is variant, the rotating speed of in time adjusting bitumenpump automatically is consistent with mass flowmeter 1 detected result with the pitch flow of guaranteeing to set; At this moment, the bituminous passage is carried in 3 conducts of verification groove, and the pitch flow is not detected; When mass flowmeter 1 is carried out verification, pitch in the pitch header tank 4 enters verification groove 3 through two-port valve 5, earlier the pitch amount in the verification groove 3 is detected, pitch is through two-port valve 7, T-valve (6), two-port valve 8, bitumenpump 2 then, by delivering in the kneading machine behind the mass flowmeter 1 detection flow, the verification groove in 3 unit time the detection flow of weighing result and mass flowmeter 1 compare check, whether satisfy service requirements to check the Measuring Precision of confirming mass flowmeter 1; The Measuring Precision of verification groove 3 is carried out verification by legal metering outfit.
When flow is excessive, too much pitch is arranged automatically to pitch storage tank by the overflow port of header tank 4, the overflow port of verification groove 3.When not producing, pitch is arranged to pitch storage tank by kneading machine by T-valve 6.
