A foaming device for foamed asphalt

Abstract

The invention discloses a foaming equipment for foamed asphalt. The structure comprises: a control box, an electric control box, an external connection pipe, an operation panel, and a foaming box. Its front position is connected to the operation panel, and the foaming box is located on one side of the control box and the two are connected to each other. The beneficial effect of the present invention is that the structure of the swinging frame and the foaming bucket are used to contact each other in the asphalt liquid and increase the generation ratio of the liquid film. , transforming from a liquid film into abundant bubbles and relying on the structure to make its dispersion in the liquid uniform.

Description

technical field [0001] The invention relates to the industrial field, in particular to a foaming equipment for foamed asphalt. Background technique [0002] As an excellent waterproof material and anti-corrosion material, foamed asphalt is widely used in industrial production industries. It needs to be heated during production. After heating, the surface tension generated by the asphalt film during the expansion process resists the steam pressure until it is balanced. Due to the low relationship between asphalt and water Thermal conductivity, the equilibrium state can generally be maintained for a few seconds, a large number of bubbles are generated during the foaming process and exist in a metastable state, but the foam is easy to burst because the foam has a nearly stable honeycomb structure of air cells , where multiple air bubbles gather, the liquid film is bent and concave toward the air chamber to form a Platt boundary, and the liquid will flow from the small curvature...

[0002] As an excellent waterproof material and anti-corrosion material, foamed asphalt is widely used in industrial production industries. It needs to be heated during production. After heating, the surface tension generated by the asphalt film during the expansion process resists the steam pressure until it is balanced. Due to the low relationship between asphalt and water Thermal conductivity, the equilibrium state can generally be maintained for a few seconds, a large number of bubbles are generated during the foaming process and exist in a metastable state, but the foam is easy to burst because the foam has a nearly stable honeycomb structure of air cells , where multiple air bubbles gather, the liquid film is bent and concave toward the air chamber to form a Platt boundary, and the liquid will flow from the small curvature to the Platt junction. This drainage effect will gradually thin the liquid film, When the liquid film reaches a critical thickness, the film will burst, which means that the amount of foam will decrease, which will seriously affect the foaming index of asphalt. Based on the above premise, a foaming equipment for foaming asphalt was developed in this case to solve this problem.
