Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0024] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0025] Such as figure 1 As shown, the present invention provides a kind of regenerated emulsified asphalt pumping equipment, comprising:

[0026] The storage tank 1 stores pre-prepared regenerated emulsified asphalt inside, and the regenerated emulsified asphalt is prepared by stirring waste asphalt mixture, solvent, emulsifier, active filler and water. The upper part of the storage tank is provided with an inlet 11 that allows the pre-prepared regenerated emulsified asphalt to enter, and the lower part of the storage tank is provided with an outlet 12 that allows the pre-prepar...

Abstract

The invention relates to delivery devices for asphalt, in particular to a pumping device for regenerated emulsified asphalt. The pumping device comprises a storage tank, a measuring tank, a first delivery pump, a second delivery pump, a third delivery pump and a fourth delivery pump, wherein the regenerated emulsified asphalt is stored in the storage tank, an inlet is formed in the upper portion of the storage tank, and an outlet is formed in the lower portion of the storage tank; the input end of the measuring tank is connected to the outlet of the storage tank, and two parallel output pipelines are arranged at the output end; a first emulsifying agent is contained in the first delivery pump, and a pair of first stirring rollers which rotate in the axial direction of the second delivery pump are arranged in the second delivery pump; and a second emulsifying agent and active filler are contained in the third delivery pump, a plurality of second stirring rollers which are perpendicular to the axial direction of the third delivery pump are further arranged in the third delivery pump, and a spiral condensing pipe is arranged in the fourth delivery pump. The invention further relates to a method for pumping the regenerated emulsified asphalt through the pumping device. By the adoption of the pumping device and the pumping method, the regenerated emulsified asphalt is prevented from being further aged in the delivery process, and the usability of the regenerated emulsified asphalt is improved.

Description

technical field [0001] The invention relates to an asphalt conveying device and method. More specifically, the present invention relates to a regenerated emulsified asphalt pumping equipment and pumping method. Background technique [0002] Asphalt pavement regeneration technology is to dig, recycle, crush and screen the old asphalt pavement that needs to be renovated or discarded, and then mix it with new aggregate and new asphalt materials to form recycled asphalt with certain road performance. Mixture, a complete set of technology for paving the surface layer or base layer of the pavement. In the transportation process of regenerated emulsified asphalt, most of the utilization of asphalt in recycled asphalt pavement materials is by hot melt method, which not only wastes a lot of fuel, but also makes the prepared regenerated emulsified asphalt further aging, which affects the technology of asphalt performance. Contents of the invention [0003] It is an object of the ...
