Pitch pre-treating and dispersing device with weighing function

Abstract

The invention relates to a pitch pre-treating and dispersing device with a weighing function. The device is characterized by comprising a material mixing barrel (1), a stirring machine (6) and a stirring barrel (7), wherein a pneumatic pump (2) is fixed at the top of the material mixing barrel (1); the liquid inlet and the liquid outlet of the pneumatic pump (2) are communicated with the interior of the material mixing barrel (1); a dispersing device (8) is arranged above the stirring barrel (7); the dispersing device (8) comprises a stirring shaft (8.1) and dispersing plates (8.2); each of the dispersing plates (8.2) adopts a trumpet form; the caliber of the opening in one side of each of the dispersing plates (8.2) is smaller than that of the opening in the other side of the corresponding dispersing plate (8.2); a clamping sleeve (7.1) is arranged at the outer part of the stirring barrel (7); a water inlet (7.2) and a water outlet (7.3) are formed in the clamping sleeve (7.1); a weighing plate (11) is arranged at the bottom of the stirring barrel (7). According to the pitch pre-treating and dispersing device with the weighing function, pitch can be prevented from solidifying, the stirring effect of pitch is improved, and pitch quality is improved.

Description

technical field [0001] The invention relates to an asphalt pretreatment and dispersing device with weighing function, which is used for pretreatment and mixing of asphalt. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch 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. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads. [0003] At the sa...

Problems solved by technology

[0003] At the same time, the previous dispersing machine only stirred the asphalt in the mixing tank, and the mixing effect was average, and the dispersing machine dispersed the asphalt through the zigzag dispersing disc, but due to the design of the zigzag dispersing disc, the material The speed of beating is not fast, which causes the disperser to generate air bubbles when dispersing the asphalt, and the air bubbles accumulate in the mixing tank and cannot be discharged, which eventually affects the mixing effect of the asphalt and reduces the quality of the asphalt, and the previous asphalt mixing tanks did not weigh Function
