Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Structure description:

[0020] refer to figure 1 As shown, a high-uniformity foamed asphalt generating device includes asphalt deflector 1, asphalt foaming chamber 2, nozzle joint 3, anti-backflow nozzle 4, tee joint 5, heat transfer oil outlet 6, and asphalt foam homogenizing plate 7. Spiral mixing mechanism 8, spiral blade 81, mounting plate 82, foamed asphalt sampling pipe 9, sampling solenoid valve 10, heat transfer oil inlet 11, vortex area 12, further, the asphalt deflector 1 is circular, and its thickness is greater than 20mm, its diameter is the same as the inner diameter of the asphalt pipe, and the cross-section of the 2-3 diversion holes on it can be circular, elliptical and square, and the diversion holes can be columnar or frustum-shaped through holes. The orifice causes the asphalt to generate a negative pressure area at ...

Abstract

The invention relates to a high-uniformity foam asphalt generating device, comprising an asphalt guide plate (1), an asphalt foaming cavity (2), a nozzle joint (3), an anti-reflux nozzle (4), a tee joint (5), a heat conducting oil outlet (6), an asphalt foam homogenizing plate (7), a spiral stirring mechanism (8), a foam asphalt sampling tube (9), a sampling solenoid valve (10) and a heat conducting oil inlet (11).

Description

technical field [0001] The invention relates to a foamed asphalt generating device, in particular to a foamed asphalt generating device with high foaming efficiency, good foam uniformity, automatic cleaning and automatic sampling. Background technique [0002] At present, problems in the production of conventional hot-mix asphalt mixtures such as serious asphalt aging, high energy consumption, large emissions of harmful gases and asphalt fumes, and high construction temperature requirements have become increasingly prominent. As a relatively new technology, foamed asphalt warm mixing technology has attracted extensive attention in recent years because of its advantages of energy saving, emission reduction, environmental protection, and low cost of use. Most of the foamed asphalt production equipment used in China is imported from abroad, and mainly consists of two structures: multi-asphalt nozzles controlled by cylinders and single asphalt foaming pipes. The former is suitab...
