Embodiment Construction

[0013] Reference figure 1 , The asphalt foaming device of the present invention is mainly composed of a middle-pass pipe 1 and a spiral stirring rod 2. The spiral stirring rod 2 is arranged inside the middle-pass pipe 1, and the spiral stirring rod 2 is driven by a motor.

[0014] One end of the middle-pass pipeline 1 is an asphalt inlet 3, during operation, high-temperature asphalt enters the pipeline from this inlet 3. In order to increase the pressure and speed when the asphalt enters, the inlet 3 is preferably designed in a bell mouth shape. The other end of the middle-pass pipe 1 is an asphalt outlet 4, and the asphalt is output through the outlet 4 after completing the foaming reaction in the pipe 1.

[0015] The inside of the spiral stirring rod 2 is provided with a through water channel 5, the input end of the through water channel is connected with a high-pressure water source, and the output end of the through water channel 5 is a water outlet hole 6 provided on a spiral ...

Abstract

The invention discloses an asphalt mixing device. The asphalt mixing device comprises a hollow pipeline, wherein an asphalt feeding opening and an asphalt discharging opening are formed in two ends of the hollow pipeline, a screw-type stirring rod is arranged in the hollow pipeline, a through water channel which is communicated with a high-pressure water source is arranged inside the screw-type stirring rod, and a water outlet hole which is communicated with the through water channel is formed in each screw stirring blade. The through water channel is directly arranged in the screw-type stirring rod, the screw-type stirring rod is used for stirring the asphalt and spraying the water to the asphalt through the water outlet holes, the sprayed water can be adequately contacted with the asphalt to have reaction, so that a good foaming effect can be achieved; under the effect of the sprayed water, the water outlet holes in the screw-type stirring blades are not blocked, and the application effect is guaranteed.

Description

Technical field [0001] The invention relates to an asphalt processing device, in particular to an asphalt mixing device. Background technique [0002] Asphalt foaming is a commonly used asphalt treatment process. The main principle is to add cold water to the high-temperature asphalt. The hot asphalt exchanges heat with the surface of the water droplets. The water droplets are heated and evaporated to produce steam. These steam make the asphalt produce fine foam. Thus expanding. In this state, the viscosity of the asphalt is significantly reduced, and it can be easily mixed with the cold and wet particles evenly. [0003] In the prior art, a mechanical foaming device is generally used to foam bitumen. It mixes water and high-temperature bitumen into the container to cause the water body to react with the bitumen. The mixing blades installed in the container are mainly used to make the bitumen and bitumen. Full contact with water. However, tests have proved that the foaming effec...
