Working device for crushing and drying mine asphalt

Abstract

The invention relates to a working device for crushing and drying mine asphalt. The working device comprises a feeding system, a crushing system, a conveying system and a heating system, wherein the feeding system is connected above the crushing system; the conveying system is connected to the bottom of the crushing system; the heating system is connected above the conveying system; the conveying system comprises a servo motor, an auger and a conveying box; the auger is movably connected into the conveying box; the servo motor is connected with one end of the auger; a feed port and a discharge port are respectively formed in the top and the bottom of the conveying box; the feed port is connected to the bottom of the crushing system; the heating system is connected to the top of the conveying box; a through hole is formed in the top of the conveying box; and the heating system is communicated with the conveying box through the through hole. As the working device crushes and dries the mine asphalt in the conveying process, the water content of the mine asphalt is reduced, and the leaching efficiency of asphalt oil is improved.

Description

technical field [0001] The invention relates to the technical field of asphalt production, in particular to a working device for crushing and drying ore asphalt. Background technique [0002] Due to the high oil content and small particle size of bituminous ore, the particle size of most particles is 2-7 μm, and the maximum particle size does not exceed 12 μm. Therefore, the smaller the particle size of the raw material used for extraction, the better the leaching of asphalt oil, because the particle size of the raw material is too large, which is not conducive to solvent penetration, and the asphalt oil in the large particles is not easy to leach, but the particle size is too small, so the crushing cost is higher Uneconomical. Generally, the particle size is required to be 2-6mm. Since the solubility of asphalt oil in solvents decreases with the increase of water content, and the water content is too high, it also affects the energy consumption of subsequent separation fr...
