Asphalt mixing device

Abstract

The invention discloses an asphalt mixing device. The device comprises a mixing barrel, an ion purifier and a motor, wherein a bearing block is arranged in the middle of the lower side of the mixing barrel; a discharging port is formed in the lower side surface, close to the mixing barrel, of the left side of the bearing block; a heating ring is arranged on the outer side surface of the mixing barrel; a base is arranged on the lower side surface of the bearing block; a feeding port is formed above the left side of the mixing barrel; a planetary gear set is arranged at the top of the mixing barrel; a sun gear and a planetary carrier are correspondingly connected with a main mixing shaft and a shaft sleeve, so that the two shafts can gain rotating torque in opposite rotating direction and at different rotating speed; the mixing operation can be carried out at the upper layer and the lower layer at different rotating speed and in different rotating direction in the mixing barrel, relative motion between materials is closer, and as a result, the mixing effect is improved; in addition, the ion purifier is arranged at the top of the mixing barrel and can be used for ionizing and purifying harmful gas dispersed in a mixing process, the body health of workers can be ensured, and the atmosphere environment is protected.

Description

technical field [0001] The invention belongs to the technical field of asphalt production and processing, and in particular relates to an asphalt mixing device. Background technique [0002] Asphalt is a kind of high viscosity organic liquid, the surface is black, soluble in carbon disulfide. Most of them exist in the form of asphalt or tar. Asphalt can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking, and petroleum pitch is the residue after crude oil distillation. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. [0003] During the mixing operation of the original asphalt mixing device, due to the high viscosity of the asphalt, the mixing speed cannot be too high, resulting in a long mixing process. In addition, because the asphalt mixing needs to be heated, some irritating gases are emitted, which affects the operato...
