Asphalt melting device for highway engineering

Abstract

The invention discloses an asphalt melting device for highway engineering, wherein the asphalt melting device for highway engineering comprises a cylinder body; an outer ring strip is fixedly mounted at the position, close to the middle, of the outer surface of the cylinder body; the outer ring strip is movably connected with two outer cylinder sleeves, and the two outer cylinder sleeves are movably connected to the left side and the right side of the cylinder body; an annular groove is formed in the position, close to the middle, of the interior of each outer barrel sleeve, the outer annular strip is clamped into the annular grooves, supporting legs are fixedly mounted on the outer surface of the lower ends of the outer barrel sleeves, a heating mechanism is fixedly mounted in the cylinder body, and a feeding mechanism is fixedly mounted on the outer surface of the upper end of the cylinder body. The device can reduce accumulation of crushed asphalt, ensure uniform heating of the crushed asphalt, prevent asphalt raw materials from being mixed into fluid asphalt, improve the finished product quality of the fluid asphalt, reduce adhesion of the fluid asphalt to the cylinder wall, keep the discharge cylinder opening unobstructed, accelerate the asphalt outflow speed and effectively improve the use efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of asphalt melting, in particular to an asphalt melting device for highway engineering. Background technique [0002] With the rapid development of my country's infrastructure construction, public facilities are becoming more and more perfect, and road construction is the foundation of all construction. The total amount of roads maintained has greatly increased. Asphalt is an indispensable raw material for road maintenance. Asphalt in storage is a hard black solid, which is also mixed with a large amount of impurities such as stones. Before using asphalt, the raw material must be heated to melt it. Unmelted asphalt raw material Most of them exist in the form of solids with different sizes. When they are melted, they tend to melt unevenly and cause agglomerated asphalt to mix into the interior of fluid asphalt, resulting in a decrease in the quality of asphalt and affecting its use. [0003] The existing pat...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been solved: 1. Although the above-mentioned device has realized the melting of asphalt safely and efficiently, reduced the accident rate, and improved work efficiency, but the asphalt block When broken and falling, not only can’t buffer the falling asphalt block, reduce the damage to the spray pile of the heating cylinder, but also can’t evenly fall into the heating cylinder, easy to form accumulation, in addition, there will still be unmelted asphalt raw materials in the crushed asphalt Mixing with fluid asphalt will cause the overall quality to deteriorate first and affect the use; 2. When the melted asphalt is discharged, it is necessary to keep the discharge port unobstructed and clean, not only to avoid the agglomeration of the discharge port from being brought into the fluid asphalt, And it is necessary to keep the discharge port unobstructed to facilitate the downflow and removal speed of asphalt
