Description
Technical field
The present invention relates to the detection of emulsified asphalt medium pitch effective content, can carry out the detection of common emulsified asphalt, modified emulsifying asphalt Asphalt Content.
Background technology
Emulsified asphalt is as the cold construction material of one, along with its ripe production technology, and the pavement performance of high-quality, simple construction technology, more and more receives professional quarters' concern.Emulsified asphalt is mainly made up of water, emulsifying agent, additive and pitch, and the content of its performance and pitch is closely related.Therefore the effective content of, guaranteeing pitch is the key that ensures emulsified asphalt quality.
At present, the equipment of emulsified asphalt is produced in batch production, general per hourly reaches several tons even tens tons, and therefore, per minute is produced with regard to the emulsified asphalt that has up to a hundred kilograms, is difficult to accurately control the content of emulsified asphalt only according to the adjustment of equipment itself.How can determine fast the content of emulsified asphalt, guarantee the quality of production of emulsified asphalt, most important.
Emulsified Bitumen at Abroad detects, production technology, and the U.S. goes on along in the prostatitis in the world, and the emulsified asphalt residue test method of ASTM has been subjected to accreditation widely in the world, is mainly divided into evaporation method and the way of distillation.
The emulsified asphalt residue test evaporation method of ASTM mainly contains ASTM D6934, ASTMD7404 and ASTMD7497.ASTM D6934 gets about 50g emulsified asphalt sample in container, and moisture is removed in the baking oven evaporation being placed under limiting temperature, or puts into baking oven after heating evaporation again.The method needs respectively 3h and 1h, and experimental period is longer, for produced on-site, within 3 hours, has had tens tons of productions out; ASTM D7404 measures emulsified asphalt residue with moisture analyser, and can obtain at short notice experimental result, and automaticity is high, but cost of equipment is higher, is difficult to popularize.ASTM D7497 adopts low-temperature evaporation technology, and the lower time of low temperature exceedes 1 day, cannot be used for produced on-site.
Domestic existing method for normalizing is on the test method basis of ASTM, determines with reference to Japanese specification, and detection time is longer, is not suitable with the needs of plant produced.
Comprehensive analyze domestic and international present Research, in batch production production testing, require the relatively accurate in a short period of time content that detects emulsified asphalt, and equipment, technique are simple, are easy to promote.Therefore, we have designed emulsified asphalt effective content rapid measurement device, can measure fast pitch effective content, for production, the processing high efficient and reliable of emulsified asphalt, provide technical support.
Summary of the invention
For defect or the deficiency of prior art, the purpose of this utility model is to provide a kind of rapid measurement device of emulsified asphalt Asphalt Content.With solve existing emulsified asphalt effective content efficiency when factory and the site survey not high, need to carry more weighing, heating, mixing plant, the shortcoming such as measuring result error is larger.
The measurement mechanism of the emulsified asphalt Asphalt Content that for this reason, the utility model provides comprises:
Sample hose: for holding emulsified asphalt to be measured;
Microwave heating pipe: heat for the emulsified asphalt to sample hose;
Meausring apparatus: for the quality of emulsified asphalt to be measured;
Temperature sensor: be placed in microwave heating pipe;
Display: for the weighing value of detected value and the meausring apparatus of displays temperature sensor;
Described microwave heating pipe is placed on described meausring apparatus, and described sample hose is placed in described microwave heating pipe.
Preferably, described display is installed on described meausring apparatus.
Further, the measurement mechanism of described emulsified asphalt Asphalt Content also comprises top cover, and this top cover is placed on microwave heating pipe, runs off for the heat that limits heating process, offers steam hole on this top cover simultaneously.
Preferably, described sample hose is of a size of: diameter 30mm, high 100mm.
Compared with prior art, the utility model has the advantage of:
(1) master trip instrument is connected with Weighing system, is then connected with control system, makes the globality of this measurement mechanism better.
(2) pick-up unit is small and exquisite, by a large amount of evidences, the sample quality of code requirement is reduced to 10g, and measured bitumen content result degree of accuracy is high, measurement required time is short.
(3) microwave refers to the electromagnetic wave of frequency at 300MHz～300GMz.Under the effect of microwave electromagnetic field, the polar molecule in dielectric material transfers to and follows the friendship table of microwave electromagnetic field and oriented from original thermal motion state, and microwave energy is converted into the heat in medium, makes material temperature be rendered as the rising in macroscopic view.Microwave heating is current state-of-the-art asphalt pavement material heating means; have that speed is fast, homogeneous heating, thermograde is little, heat loss is few; the flames of anger, without the advantage such as weak seam and weak junction, repairing quality be high and pollution-free; meet that national energy-saving reduces discharging, the requirement of environmental protection, can meet that HIGHWAY MAINTENANCE enters fast, sharp work, the need of work withdrawn fast.Measurement mechanism of the present utility model adopts microwave heating, and environment-friendly high-efficiency is less to the harm of environment.
To sum up, apparatus structure of the present utility model is simple, practical, little to environmental hazard, can realize the fast detecting to emulsified asphalt Asphalt Content.
