Abstract

The invention relates to the field of asphalt processing, in particular to a smoke suppression asphalt mixing device which comprises a box and a stirring shaft rotatably connected to the box and further comprises a piston barrel, a piston is slidably connected into the piston barrel, a spring is connected between the inner wall of the piston barrel and the piston, a piston rod is fixedly connected to the piston, and a piston plate is connected to the piston rod. An air channel is arranged between the piston barrel and the box, a first one-way valve used for enabling air in the box to flow into the piston barrel in a one-way mode is arranged on the air channel, an air outlet is formed in the piston barrel, a second one-way valve used for enabling the air in the piston barrel to flow out in a one-way mode is arranged on the air outlet, and an air collecting piece is connected to the air outlet; and a protruding piece is fixedly arranged on the portion, located on the outer side of the box, of the stirring shaft and intermittently abuts against the piston plate. According to the scheme, waste gas generated in the mixing process is collected.

Description

technical field [0001] The invention relates to the field of asphalt processing, in particular to a smoke-suppressing asphalt mixing device. Background technique [0002] Asphalt is a product of the petroleum industry with complex components. A large number of studies have shown that at high temperature, the light components of asphalt are easily cracked, volatilized and separated from the asphalt system, thereby releasing a large amount of toxic asphalt fumes. When the asphalt mixture reaches about 180°C, the asphalt fume released can reach 10-12mg / m 3 , which contains more than 100 kinds of organic substances, which directly damage the health of construction workers, and these substances will cause great pollution to the environment. [0003] In the prior art, during the mixing process of asphalt mixture, the collection and treatment of toxic waste gas are not considered, and the toxic and harmful gases such as asphalt smoke generated during the production of asphalt mixt...
