Rapid melting device for solid blocky asphalt

Abstract

The invention discloses a rapid melting device for solid blocky asphalt. The device comprises a device main body with an internal cavity, a material elevator is mounted above the top of the device main body; a material falling opening is formed in the top face of the device main body, a solid blocky asphalt constant-temperature thermal cutting system is installed in the material falling opening, the material elevator can convey solid blocky asphalt into the material falling opening, and the solid blocky asphalt is divided by the solid blocky asphalt constant-temperature thermal cutting systemand then directly falls into an inner cavity of the device main body. A horizontal stirring and dispersing system and an asphalt heating and melting system are installed in an inner cavity of the device main body, and the asphalt heating and melting system is located below the horizontal stirring and dispersing system and connected with a smoke exhaust system. The device effectively solves the problems of non-uniform heating, low melting speed and high energy consumption of blocky asphalt, prevents the asphalt from being repeatedly heated, and has the effect of preventing the asphalt from aging.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a device for rapidly melting solid block asphalt. Background technique [0002] Asphalt has the physical properties of being solid at room temperature and liquid at high temperature. Solid asphalt is difficult to melt and is inconvenient to use. Therefore, asphalt is generally melted at high temperature in advance to become liquid asphalt and then transported to the place of use by a specific asphalt truck. The asphalt transport vehicle is covered with iron sheets and lined with high-tech heat insulation materials. The heat preservation time is long. Heating pipes are installed in the tank to conduct heat. There are three heating methods: steam heating, coal heating, and diesel blowtorch heating. However, the use of asphalt trucks to transport asphalt has disadvantages such as high risk, repeated heating, and high cost in remote areas. [0003] At present, i...

However, the use of asphalt trucks to transport asphalt has disadvantages such as high risk, repeated heating, and high costs in remote areas

[0003] At present, in the prior art, there is also a process for on-site melting of block asphalt. Generally, the existing process is oil pool immersion melting. However, due to structural defects in this melting device, it is easy to cause uneven heating of block asphalt and melting. The speed is slow, and it is easy to cause asphalt aging. At the same time, because all the asphalt in the melting device must be heated for a long time during the heating process, its energy consumption is also very high
