Embodiment Construction

[0022] The present invention will be further described below through specific embodiments.

[0023] refer to figure 1 As shown, the asphalt mixture drying drum includes a support 1 , a cylinder body 2 , a driving device 3 , a burner 4 , a feeding chute 5 and a belt conveying device 6 . The support 1 is arranged obliquely, and the barrel 2 is erected on the support 1 in a high-low arrangement, the higher end is the feed end of the barrel 2, and the lower end is the discharge end of the barrel 2. The cylinder body 2 includes an inner cylinder body 21 , an outer cylinder body 22 , a feed end seat 23 , an inner cylinder body discharge end seat 24 and an outer cylinder body discharge end seat 25 . The inner cylinder 21 and the outer cylinder 22 are coaxially arranged and fixed by welding, and a material cavity 26 for accommodating asphalt material is formed between the inner cylinder 21 and the outer cylinder 22 . The feed end seat 23, the inner cylinder body discharge end seat 2...

Abstract

The invention belongs to the technical field of asphalt concrete stirring, and in particular relates to an asphalt mixture drying drum capable of drying two kinds of asphalt materials at the same time. The drum comprises a drum body, a bracket, a driving device and a burner, wherein the drum body is arranged on the bracket through the driving device; the driving device can drive the drum body to rotate on the bracket; and the burner is connected with the drum body and is used for heating the interior of the drum body. The asphalt mixture drying drum is characterized in that the drum body is erected on the bracket, and is arranged in a manner of forming a certain included angle with the horizontal plane in the upper-lower direction; the high end of the drum body serves as a feed end, and the lower end of the drum body serves as a discharge end; the drum body comprises an internal drum body and an external drum body; the feed ends and the discharge ends of the internal drum body and the external drum body are respectively provided with feed ports and discharge ports; a material cavity for containing the asphalt materials is formed between the internal drum body and the external drum body; and the discharge port of the internal drum body is not communicated with the material cavity. The regeneration drum can dry the two kinds of asphalt materials at the same time, thus avoiding the problems of nonuniform heating, asphalt ageing and the like, and the heating efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of asphalt concrete mixing, and in particular relates to an asphalt mixture drying drum which can simultaneously dry two kinds of asphalt materials. Background technique [0002] At present, the double-layer drying drum includes an inner cylinder and an outer cylinder. The inner cylinder and the outer cylinder are connected through the material guide hole. The asphalt material first enters the inner cylinder after drying, and then enters the inner cylinder and the outer cylinder through the material guide hole. The second drying is carried out in the interlayer, and the dried asphalt material is discharged from the discharge port of the outer cylinder. The existing asphalt drying drum has the following problems: one is that the heating temperature required for different existing asphalt materials is different, so the existing double-layer drying drum can only dry one kind of asphalt material at a time; The ...
