Foaming equipment of foamed asphalt

Abstract

The invention discloses a foaming equipment of foamed asphalt. The equipment structurally comprises a control box, an electric control box, an external connection pipe, an operation panel and a foaming box, the electric control box and the external connection pipe are arranged on the side edges of the control box respectively, the front face of the control box is connected with the operation panel, and the foaming box is located on one side of the control box and connected with the control box. The equipment has the beneficial effects that: the structure that a swing frame is matched with a foam increasing hopper is used for making contact with asphalt liquid, the generation proportion of a liquid film is increased, the liquid film is converted into rich bubbles, and the dispersion degreeof the bubbles in the liquid is uniform through the structure.

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.
