Abstract

The present invention relates to a kind of liquid asphalt metering device, including the asphalt box (1) for providing liquid bitumen, characterized by further comprising for measuring liquid bitumen and by the pitch hopper (2) of liquid bitumen High voltage output, for the driving cylinder (3) for the piston for driving pitch hopper, PLC (5), the asphalt box (1) is connected by switch valve (11) with pitch hopper (2), displacement transducer (4) is housed on the piston or piston rod of the pitch hopper (2), the displacement transducer (4) is connected with PLC (5), the driving cylinder (3) is controlled by PLC (5).The present invention is simple in construction, either under compared with strong vibration state, or under various putting position states, can reliably work, it is ensured that the degree of accuracy of liquid bitumen metering, ensure that asphalt concrete quality.

Description

Liquid asphalt metering device
Technical field
The present invention relates to pitch process equipment, more particularly to a kind of liquid asphalt metering device.
Background technology
The pitch metering device used on present asphalt mixing apparatus mainly has two kinds, and one kind is to use weight sensor (being commonly called as piezoelectric transducer) and computer technology, and one kind is using weight displacement sensing and computer technology.Both Weighing devices are static weighing technology, when asphalt mixing apparatus works, because necessarily vibration and the different of mixing apparatus putting position all cause static weighing measuring accuracy greatly to decline caused by mixing apparatus work, ratio of precision can be uncontrollable below 2%, and the quality fluctuation of asphalt is had a great influence.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of liquid asphalt metering device that can effectively improve measuring accuracy.
The object of the present invention is achieved like this:A kind of liquid asphalt metering device, including the asphalt box for providing liquid bitumen, also include being used for measuring liquid bitumen and by the pitch hopper of liquid bitumen High voltage output, the driving cylinder of piston for driving pitch hopper, PLC, the asphalt box is connected by switch valve with pitch hopper, displacement transducer is housed on the piston or piston rod of the pitch hopper, the displacement transducer is connected with PLC, and the driving cylinder is controlled by the signal of displacement transducer by PLC.
Compared with prior art, the beneficial effects of the invention are as follows:
The present invention is simple in construction, either under compared with strong vibration state, or under various putting position states, can reliably work, it is ensured that the degree of accuracy of liquid bitumen metering, ensure that asphalt concrete quality.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Referring to Fig. 1, the present invention relates to a kind of liquid asphalt metering device, including asphalt box 1, pitch hopper 2, driving cylinder 3, asphalt box 1 is connected by switch valve 11 with asphalt delivery cylinder 2, the piston of pitch hopper 2 is driven by driving cylinder 3, displacement transducer is housed, the displacement transducer 4 is connected with PLC 5, and PLC 5 controls driving cylinder 3 by hydraulic station 6 on the piston or piston rod of pitch hopper 2.
When the present invention uses, the pitch weight amount of needs is first inputted PLC 5 by operator, the gravimetric value is converted into piston should move in pitch hopper distance to a declared goal according to the density of liquid bitumen and stored by PLC 5, then start key is pressed, driving cylinder 3 starts to drive the piston of pitch hopper to move right liquid bitumen in draw pitch case, the location information data of piston is constantly sent to PLC by the displacement transducer 4 on piston, when the real time data of transmission is consistent with the data in PLC, PLC sends instruction to hydraulic station 6 acts driving cylinder stopping.Now complete the metering of asphalt content.When driving cylinder inverted running, the piston in pitch hopper 2 pushes away pitch, is mixed and stirred with compound.Metering of the present invention to pitch is very accurate, can make the control of asphalt mixing ratio error within 0.5%.
