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] Such as figure 1 and figure 2 As shown, a kind of asphalt feeding and mixing device includes a heating mechanism 1 for heating asphalt and a stirring mechanism 2 for stirring asphalt. The heating mechanism 1 includes a storage cylinder 11 for holding asphalt. 2 includes a mixing head 21 for mixing asphalt, the mixing head 21 faces the opening of the storage tank 11, and stretches into the storage tank 11 telescopically; it also includes a feeding mechanism 3, the feeding mechanism 3 includes a material storage box 31 for containing the modifier, the material storage box 31 is provided with an air inlet and an air outlet, and the air outlet is connected with a delivery pipe 32, and the other end of the delivery pipe 32 faces The opening of the storage tank 11; the storage box 31 is also provided with a dust raising mechanism 33 for agitating the stored modifier to form dust, and the storage box 31 or the delivery pipe 32 is also provided with a useful The air in the s...

Embodiment 2

[0048] The main difference from Embodiment 1 lies in the difference of the dust raising mechanism. In this embodiment, the dust raising mechanism 33 is an air guide channel arranged in the material holding box 31, and one end of the air guide channel is connected to the air inlet The mouth is connected, and the other end is towards the bottom of the said material holding box 31.

[0049] Since the modifier contained in the material box usually gathers at the bottom of the material box under the action of gravity, the air in the material box is blown into the material tube under the action of the air supply mechanism, which will definitely make the outside world The air from the air inlet will enter into the material box through the air guide channel, and the air guide channel faces the bottom of the material tank, so that the air flowing in the air guide channel will impact the modifier gathered at the bottom of the material tank, thereby Agitate the modifier to create dust. ...

Abstract

The asphalt feeding and stirring device comprises a heating mechanism and a stirring mechanism, the heating mechanism comprises a material containing barrel used for containing asphalt, the stirring mechanism comprises a stirring head used for stirring the asphalt, and the stirring head faces an opening of the material containing barrel and stretches into the material containing barrel in a telescopic mode; the device further comprises a feeding mechanism, the feeding mechanism comprises a material containing box used for containing a modifier, an air inlet and an air outlet are formed in the material containing box, a conveying pipe is connected to the air outlet, and the other end of the conveying pipe faces the opening of the material containing barrel. A dust raising mechanism used for stirring the contained modifier to form dust raising is further arranged in the material containing box, and an air supply mechanism used for blowing air in the material containing box into the material containing barrel through the conveying pipe is further arranged on the material containing box or the conveying pipe. The asphalt modifier mixing device has the advantages of being reasonable in structure, convenient to operate and use, capable of reducing the agglomeration probability of a modifier in thermalized asphalt, capable of uniformly mixing the modifier and the like.

Description

technical field [0001] The invention relates to the field of asphalt mixing equipment, in particular to an asphalt feeding and stirring 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. affected by. Therefore, adding modifiers to asphalt to improve the performance of asphalt 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 modifiers on asphalt performance To improve the improvement effect, it is necessary to conduct modifier performance tests in the laboratory in the early stage. [0003] Before the performance test of the modifier, the modifier is first added to the heated asphalt, and then the heated asphalt is s...
