Abstract

The invention relates to an asphalt foaming machine used for preparing foamed asphalt. The foaming machine comprises a temperature adjusting asphalt stirring pot, which is connected to the inlet of an asphalt gear pump through an asphalt duct. The outlet pipeline of the asphalt gear pump is in connection with an asphalt foaming cavity. Simultaneously, a water pump and an air pump are in connection with the asphalt foaming cavity, the bottom outlet of which is opposite to an asphalt mixture stirring pot. A high power stirrer is disposed over the asphalt mixture stirring pot for stirring an asphalt mixture. The asphalt foaming machine of the invention has the advantages of simple overall structure, low manufacturing and maintenance cost, and convenient debugging and cleaning. Through reasonable adjustment and operation, the foaming machine provided in the invention can prepare foamed asphalt.

Description

technical field [0001] The invention belongs to the field of preparation of engineering material machinery, in particular to an asphalt foaming machine for preparing foamed asphalt. Background technique [0002] In modern road construction, a large amount of asphalt is required. Due to the rising price of asphalt, road builders in various countries have tried various methods to study how to save the amount of asphalt under the premise of ensuring the quality of asphalt pavement. Foamed asphalt and asphalt concrete mixed with foamed asphalt are one of the new methods ,New Technology. [0003] Compared with ordinary asphalt mixture, the asphalt mixture made with foamed asphalt has the following advantages: 1. It can reduce the amount of asphalt by 5-10%; 2. Due to the low viscosity of foamed asphalt, the time for mixing asphalt mixture can be reduced 15% to 20%, increase productivity; 3, can reduce the heating temperature of asphalt and mineral materials, thereby reducing th...
