Novel asphalt heating weighing instrument

Abstract

The invention relates to asphalt weighing equipment, in particular to a novel asphalt heating weighing instrument which comprises a bracket, an electronic scale, a weighing plate, a weighing bucket, a stirring device and a temperature measuring device, wherein the bracket is [ shaped as a whole; the electronic scale is positioned at the upper part of the bracket; the weighing plate is positioned above the electronic scale; the stirring device is positioned on the bracket in the middle of the weighing plate; the weighing bucket is positioned at the stirring device; the weighing bucket comprises an asphalt bucket and a heat conduction oil bucket; the stirring device comprises four vertical rodless cylinders, a moving plate, a motor, a rotating shaft, a rotating disc, a stirring cylinder, a stirring rod and a connecting rod; the temperature measuring device comprises a temperature measuring cylinder and a thermometer. The weight of asphalt can be detected according to data differences of two times of measurement by the electronic scale, the inaccuracy of asphalt weighing can be effectively reduced, and due to arrangement of the stirring device, asphalt in an asphalt tank can be sufficiently discharged out, and the waste of raw materials can be reduced.

Description

technical field [0001] The invention relates to an asphalt weighing device, in particular to a novel asphalt heating weighing instrument. Background technique [0002] With the rapid development of the economy, the construction of expressways in our country is increasing year by year, most of which are asphalt concrete pavement layers. When making an asphalt concrete pavement layer, in order to ensure the performance of the pavement, there are strict requirements on the ratio of asphalt to concrete. In the existing ratio test, the mineral material is put into a metal vessel to heat, then the metal vessel and the mineral material are placed on the balance, and then a certain amount of asphalt heated to liquid is poured in, and after weighing, the mineral material and the mineral material are mixed together. The asphalt is poured into a mixer for mixing and stirring. Because the heated asphalt and mineral aggregates sometimes stick to a part of the metal vessel, the total am...

AI Technical Summary

Problems solved by technology

Because the heated asphalt and mineral aggregates sometimes stick to a part of the metal vessel, the total amount of asphalt and mineral aggregates in the mixer will decrease, resulting in a difference in the final mixing ratio of asphalt and concrete from the preset ratio. This kind of experiment Uncertainty in the results will seriously affect the quality of the asphalt concrete pavement layer, and also cause waste of raw materials

[0003] The announcement number published by the Chinese patent is CN202734930U, a kind of asphalt heating weighing instrument, which can minimize the uncertainty of the mixing ratio of asphalt and mineral materials, and ensure the accuracy of experimental data, but the weighing instrument The residual asphalt on the inner wall of the asphalt tank is difficult to be discharged along with other asphalt, resulting in waste of raw materials
