Embodiment 1

[0047] A device for asphalt foaming, such as figure 1 and figure 2As shown, it includes air, water, and asphalt input, and a circulation pipeline 1 that outputs the adjusted foamed asphalt, and a control subsystem 2, so that the air, water, and asphalt are mixed and the real-time data of the output index meets the requirements of the index target data. The adjusted foamed asphalt obtained; specifically, the control subsystem 2 includes at least one set of digital sensors 21 arranged at the end of the circulation pipeline 1 to detect the real-time data of the adjusted foamed asphalt index; arranged on the circulation pipeline 1 , the actuator 22 that controls the flow state of the circulation pipeline 1; and, connected with the digital sensor 21, compares the real-time data of each index detected by the digital sensor 21 with the corresponding index target data, and controls the action of the actuator 22, in order to output The control terminal 23 of the adjusted foamed aspha...

Embodiment 2

[0059] A bitumen foaming method such as figure 1 and figure 2 shown, including the following steps:

[0060] S1. Inject heated asphalt through the foamed asphalt pipeline 13, the asphalt adopts Zhonghai 70#A grade asphalt, and the temperature of the asphalt is 150-160°C. In this embodiment of the present invention, the foaming temperature is preferably 160°C ;

[0061] S2. Inject cold water into the foamed asphalt pipeline 13 through the water supply pipeline 12. At the same time, inject compressed air into the foamed asphalt pipeline 13 through the air supply pipeline 11, wherein the volume of cold water injected into the foamed asphalt pipeline 13 is 1.5%-3% of the asphalt volume in the asphalt pipeline 13, in this embodiment of the present invention, the foaming water consumption is preferably 2.3%;

Abstract

The invention relates to the technical field of road equipment, and particularly relates to an asphalt foaming device and an asphalt foaming method. In order to solve the problems in the prior art that instrument control is not accurate enough, asphalt is aged, and the foaming quality of the asphalt is greatly reduced, the asphalt foaming device is characterized by comprising a circulation pipeline for inputting air, water and the asphalt and outputting the foamed asphalt obtained through adjustment, and a control subsystem, wherein the control subsystem comprises at least one group of digitalsensors which are arranged at the tail end of the circulation pipeline and are used for detecting index real-time data of the foamed asphalt obtained by adjustment, an execution piece which is arranged on the circulation pipeline and controls the circulation state of the circulation pipeline, and a control end which is connected with the digital sensors, compares the index real-time data detectedby the digital sensors with the corresponding index target data, and controls the execution piece to act so as to output the foamed asphalt obtained by adjustment with the index real-time data according with the index target data requirement.

Description

technical field [0001] The present application relates to the technical field of road equipment, in particular, to an asphalt foaming device and an asphalt foaming method. Background technique [0002] With the continuous enhancement of environmental protection awareness and the improvement of asphalt awareness, there are different requirements for the application fields such as changes in the physical properties of asphalt. Taking asphalt pavement construction units as an example, the emphasis on gas emission control and energy saving and emission reduction in the production process of mixing equipment requires asphalt to adopt a new model to participate in mixing, and warm mix asphalt technology has been more and more widely valued and promoted. [0003] In the prior art, when preparing foamed asphalt mixture, the foamed asphalt is usually first produced in the foamed asphalt preparation equipment, and then the foamed asphalt is passed into the mixing host and stirred with...
