Double-shaft stirring full-automatic asphalt foaming machine

Abstract

The invention discloses a double-shaft stirring full-automatic asphalt foaming machine which comprises a warm mix asphalt foaming barrel. The warm mix asphalt foaming barrel is of a double-layer-pipe structure and comprises an outer barrel and an inner barrel from outside to inside. The outer barrel is provided with a conduction oil inlet and a conduction oil outlet which are connected to a conduction oil pipe. The inner barrel is provided with a water inflow pipe communicating with a water supply tank. Two parallel stirring shafts are arranged in the inner barrel. The asphalt foaming machine can be designed in a vertical manner and in a horizontal manner as well, the occupied area is small, the foaming effect of the foaming machine is good, foaming asphalt is output to a following transporting pipe, and certain temperature and fluidity of the asphalt in the transporting pipe are guaranteed. The double-shaft stirring full-automatic asphalt foaming machine is compact and simple in structure and easy to apply in engineering.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a double-shaft stirring full-automatic asphalt foaming machine. Background technique [0002] A small amount of water is added to the high-temperature liquid asphalt. Due to the high temperature of the asphalt (generally above 140°C), when the water touches the high-temperature asphalt, it will gasify instantly and form a large number of bubbles in the asphalt, thus forming foamy asphalt. It is called foamed asphalt. Because there are air bubbles in this kind of foamed asphalt, the viscosity of the foamed asphalt is greatly reduced, and the foam increases its own volume by 2-3 times. In this way, the temperature of the mixture can be reduced, and at the same time, the uniformity of mixing and the quality of subsequent transportation, rolling and other construction can be guaranteed. This technology is called "foamed asphalt mixture warm mixing technology" in the indus...

Problems solved by technology

[0004] The above-mentioned foam tube is provided with stirring blades for stirring, which is very expensive and difficult to operate. The present invention is based on the inspiration of the cement foam machine. For example, the application number is 200820031464.9, and the invention name is a patent for a cement foam machine. An asphalt foaming machine, fully foamed in the foaming machine first, and then the asphalt is transported through the foaming pipe. At this time, the foaming pipe does not need to be as complicated as the existing technology, and only needs to ensure the flow of the asphalt during transportation just sex
