Asphalt distributing, cleaning and recovering system

Abstract

The invention belongs to roadway engineering machinery, in particular to an asphalt distributing, cleaning and recovering system used in maintenance equipment such as an asphalt distributor, a synchronized seal paver and the like. The system is provided with an asphalt tank, wherein one inlet/outlet of the asphalt tank is connected with a circulating pump through a first valve, a second inlet/outlet is connected to one port of a three-way valve, the other two ports of the three-way valve are respectively connected to the circulating pump and a first inlet/outlet of an automatic spraying circulation pipeline, and a second inlet/outlet of the automatic spraying circulation pipeline is connected with the circulating pump through a second valve; an asphalt loading pipe is arranged between the first valve and the circulating pump; the circulating pump is connected with an asphalt delivery pipe through a delivery valve; and the asphalt loading pipe is provided with a solvent pipe valve which can be connected with a remote solvent tank, and a solvent return pipe is connected between the second inlet/outlet of the automatic spraying circulation pipeline and the outlet of the asphalt delivery pipe. The invention lowers the equipment cost, and the cleaning process avoids environmental pollution.

Description

technical field [0001] The invention belongs to road surface engineering machinery, and relates to an asphalt spreading and cleaning recovery system used in maintenance equipment such as asphalt spreading vehicles and synchronous sealing vehicles. Background technique [0002] The circulation function of the asphalt spraying pipeline of the existing asphalt distributor is not comprehensive enough. The asphalt spraying pipeline is only used as a pipeline for asphalt material spraying or passing, and the function of the pipeline circulation system cannot be fully utilized. During operation, multiple sets of pipelines need to be set up to complete Different functional cycles make the whole system complex and costly. In addition, the cleaning of the spraying pipeline is mostly to use compressed air to flush the spraying pipeline after the spraying is completed. On the one hand, the asphalt cleaning is not thorough enough, and on the other hand, it also causes some pollution to t...
