A centrifugal emulsified asphalt production device and its production method

Abstract

The invention provides a centrifugal emulsified asphalt production device. A flow guiding mechanism is formed by connecting three layers of funnel-shaped flow guiding devices in series. The adjacent joints of the three layers of funnel-shaped flow guiding devices are connected with an upper flow guiding pipe and a lower flow guiding pipe respectively. The upper flow guiding pipe is connected with an upper liquid soap tank. The lower flow guiding pipe is connected with a lower liquid soap tank. An upper liquid soap pump and a lower liquid soap pump are installed on the upper flow guiding pipe and the lower flow guiding pipe respectively. The three layers of funnel-shaped flow guiding devices are each internally provided with a centrifuging device. The bottoms of the centrifuging devices are connected with motors through rotating shafts. Multiple layers of metal filter screens are installed in the centrifuging devices, and a centrifugal device housing is arranged on the top of each centrifuging device. Centrifugal force generated through rotation driven by the motors is adopted to achieve the emulsification purpose; due to emulsification of the three layers of centrifuging devices at different degrees, the emulsification efficiency is higher, emulsified asphalt particles are more uniform, emulsification quality is improved while emulsification efficiency is improved, emulsification speed is increased, and production cost is remarkably reduced.

Description

technical field [0001] The invention relates to an emulsified asphalt production device and a method thereof, in particular to a centrifugal emulsified asphalt production device and a production method thereof, belonging to the technical field of emulsified asphalt production and processing. Background technique [0002] The research on emulsified asphalt began in the last century, and it was first used in Europe, and its commercial production has been more than 60 years. Subsequently, Japan and the United States also began to research and develop emulsified asphalt and paved test roads. By the end of the 1920s, emulsified asphalt had been used for paving roads on a large scale. The use of emulsified asphalt in various countries in the world is increasing year by year, and emulsified asphalt is widely used in road paving and maintenance; although hot mix asphalt plants are common in these countries, a large amount of emulsified asphalt is still used for road construction an...

Problems solved by technology

[0003] Existing emulsified asphalt mainly relies on colloid mills for production by grinding. The main problems of this method are: (1) The material requirements for colloid mills are high, mainly imported, and the equipment is expensive; (2) During the production process, due to emulsifier Emulsification is difficult due to poor emulsification performance or insufficient asphalt temperature, which causes the colloid mill to be blocked and difficult to clean; (3) If the colloid mill is damaged, the entire grinding head needs to be replaced, and the maintenance cost is high; (3) Due to the gap between the colloid mill The adjustment accuracy and difficulty are high, and the uniformity of the particle size of the emulsified asphalt produced is insufficient, which directly affects the storage stability of the emulsified asphalt and the workability of mixing; (4) The power of the colloid mill is large, the energy consumption is high, and the production cost of the emulsified asphalt high
