Problems solved by technology

However, because the powder particles of the modifier are finer and have molecular surface energy, the finer the particles, the greater the cohesion, and when added to the thermalized asphalt, a lump will be formed, and the outer surface will be wrapped by the thermalized asphalt. It is also difficult to disperse it uniformly even if it is stirred, so that the modifier is unevenly distributed in the asphalt, resulting in a large dispersion of data collected in the final experiment, which cannot better reflect the modification effect of the modifier on the asphalt

Embodiment 1

[0030] like figure 1 and figure 2 As shown, an asphalt feeding and stirring device includes a heating mechanism 1 for heating asphalt and a stirring mechanism 2 for stirring asphalt. The heating mechanism 1 includes a container 11 for containing asphalt. The stirring mechanism 2. It includes a stirring head 21 for stirring asphalt, the stirring head 21 faces the opening of the material container 11 and extends into the material container 11 telescopically; it also includes a feeding mechanism 3, the feeding mechanism 3. Including a container 31 for containing the modifier, the container 31 is provided with an air inlet and an air outlet, and the air outlet is connected with a conveying pipe 32, and the other end of the conveying pipe 32 faces The opening of the material holding cylinder 11; the material holding box 31 is also provided with a dust raising mechanism 33 for stirring the contained modifier to form dust, and the material holding box 31 or the conveying pipe 32 is...

Embodiment 2

[0048] The main difference from Embodiment 1 lies in the dust raising mechanism. In this embodiment, the dust raising mechanism 33 is an air guide duct arranged in the container 31 , and one end of the air guide duct is connected to the air intake. The ports are connected, and the other end faces the bottom of the container 31 .

[0049] Because the modifier contained in the container usually gathers at the bottom of the container under the action of gravity, the air in the container is blown into the container under the action of the air supply mechanism, which will definitely make the outside The air will enter the container from the air inlet through the air guide, and the air guide will face the bottom of the container, so that the air flowing in the air guide will impact the modifier accumulated at the bottom of the container, thereby Agitate the modifier to form fugitive dust.

[0050] During implementation, the lower end of the air guide duct is arranged along the circ...

Abstract

The invention discloses an asphalt feeding and stirring device, comprising a heating mechanism and a stirring mechanism, wherein the heating mechanism comprises a container for holding asphalt, the stirring mechanism comprises a stirring head for stirring the asphalt, the stirring head toward the opening of the material container, and extend into the material container telescopically; it also includes a feeding mechanism, the feeding mechanism includes a container for containing the modifier, and the container is on the top of the container. An air inlet and an air outlet are provided, and a conveying pipe is connected to the air outlet, and the other end of the conveying pipe faces the opening of the material holding cylinder; A dust raising mechanism is formed by stirring the agent to form dust, and a blowing mechanism for blowing the air in the container to the container through the conveying pipe is also provided on the container or the conveying pipe. The present invention has the advantages of reasonable structure, convenient operation and use, can reduce the probability of agglomeration of the modifier in the thermalized asphalt, and can mix the modifier uniformly.

Description

technical field [0001] The invention relates to the field of asphalt mixing equipment, in particular to an asphalt feeding and mixing device. Background technique [0002] At present, asphalt concrete pavement is the main surface layer of high-grade highways in my country, while ordinary asphalt pavement often has the characteristics of low temperature cracking, high temperature deformation and poor water stability. These reasons are mainly due to the high temperature performance, low temperature performance and water temperature properties of asphalt in asphalt concrete affected. Therefore, adding modifiers to asphalt to improve asphalt performance has become the focus of research, and modifiers are mostly powder particles, such as graphene, steel slag, slaked lime and cement and other non-polar additives. In order to study the effect of modifiers on asphalt performance The improvement effect of the modifier needs to be tested in the laboratory in the early stage. [0003]...
