Abstract

The invention relates to an asphalt spraying and conveying device with a cleaning function. The asphalt spraying and conveying device comprises a hot asphalt box (1), an asphalt delivery stop valve (3), an asphalt pump (4), an asphalt spraying stop valve (5), an asphalt sprayer (6), an oil return stop valve (8), a diesel oil tank (11) and a diesel oil stop valve (13), wherein the asphalt pump (4), the oil return stop valve (8), a first oil return pipe (7), a second oil return pipe (9), a first three-way pipe (10), a second three-way pipe (14) and a third three-way pipe (15) form a diesel oil cleaning circulation pipeline system; and the diesel oil tank (11) is connected with the third three-way pipe (15) through a diesel oil conveying pipe (12). The asphalt spraying and conveying device can conveniently clean residual asphalt in the asphalt pump, so that the cleaned asphalt pump is always in a state capable of freely starting and cannot be frozen by cooled asphalt; and unsafe operation, such as flame baking and the like, is avoided. The asphalt spraying and conveying device is low in using cost.

Description

technical field [0001] The invention relates to an asphalt spraying device in the construction of asphalt pavement, in particular to a cleaning asphalt spraying conveying device. Background technique [0002] Since the asphalt pumps of the current distribution vehicles are installed outside the asphalt tank, the asphalt pumps must be heated every time they are started, which not only wastes time and effort, affects the construction quality, but also has potential safety hazards. Existing technologies such as figure 1 In the shown device, when the asphalt delivery shut-off valve 3, asphalt spray shut-off valve 5 are opened and the oil return shut-off valve 8 is closed, when the asphalt pump 4 is started, the hot-melt liquid asphalt is sucked out from the hot asphalt tank 1 and passed through the oil suction pipe. 2, asphalt delivery cut-off valve 3, asphalt pump 4, first tee 10 and asphalt spray stop valve 5, are sprayed to the road surface from asphalt nozzle 6. When it is...
