Thermal regeneration bitumen material conveying device

Abstract

The invention relates to asphalt production equipment for road construction, in particular to a thermal regenerative asphalt conveying device used for conveying the hot asphalt regenerative material. The thermal regenerative asphalt conveying device includes a conventional thermal regenerative asphalt metering cylinder and a conventional batch type mixing equipment; a continuous mixing bowl is arranged at the lower part of a discharge port of the thermal regenerative asphalt, and the discharge port of the continuous mixing bowl is connected with the mixing bowl of the batch type mixing equipment. An insulating layer filled with a heat-insulating material is arranged on the continuous mixing bowl. Also an additive metering cylinder is arranged at the upper part of the continuous mixing bowl and the discharge port of the additive metering device is communicated with the feed inlet of the continuous mixing bowl. The invention can smoothly convey the thermal regenerative asphalt to the mixing equipment of the mixtures, reduce the conglutination and blockage during the convey process, and can shorten the mixing time and improve the construction efficiency.

Description

technical field [0001] The invention relates to asphalt production equipment for road construction, in particular to a hot asphalt raw material conveying device for conveying hot asphalt recycled materials. Background technique [0002] Thermal regeneration of asphalt concrete is of great significance for saving resources and protecting the environment. The existing asphalt thermal recycling equipment is to add a set of independent downstream drying drums and metering devices to the standard batch asphalt mixing equipment. The recovered recycled materials are dried by independent heating and weighed. It is transported into the mixing tank of the standard batch mixing equipment within a certain period of time, and re-mixed with new asphalt materials, new aggregates and required additives in a certain proportion to form a new mixture. In this kind of equipment, due to the adhesion of the hot recycled asphalt material, it will cause adhesion and blockage during the transportat...

AI Technical Summary

Problems solved by technology

In this kind of equipment, due to the adhesion of hot recycled asphalt materials, it will cause adhesion and blockage during the transportation process, which will affect the normal operation of the equipment.

In addition, because the additives are mixed with the new and old asphalt materials in the batch mixing equipment, the mixing time is prolonged and the construction efficiency is reduced.
