A kind of asphalt wet forming device and forming process

Abstract

The invention relates to an asphalt wet forming device and a forming process. The forming device includes a forming plate, a forming tank, a dehydration conveyor, a gas-water separator and a hot water tank. Liquid asphalt is dripped into the forming tank through a small hole at the bottom of the forming plate , form small droplets and finally become granular products and discharge from the bottom of the forming tank. The bitumen particles discharged from the bottom of the forming tank enter the dehydration conveyor, and most of the water carried by the bitumen particles flows from the holes of the conveyor belt to the lower water collection tank. Then it is discharged to the hot water tank through the pipeline, and the moisture carried on the surface of the remaining particles is pumped to the gas-water separator by the fan and the dehydration bellows at the rear of the dehydration conveyor, and the separated water is collected and discharged to the hot water tank. After the water is cooled by the heat exchanger, it is pumped to the forming tank. The asphalt wet forming device and process of the present invention have the advantages of a short process flow for asphalt forming, less investment in equipment required for the process, uniform spherical particles of finished asphalt after forming, and low moisture content.

Description

technical field [0001] The invention relates to the technical field of asphalt forming, in particular to an asphalt wet forming device and a forming process thereof. 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 and has a black surface. It is soluble in carbon disulfide. organic gelling materials. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads. The upstream of the asphalt industry is petrochemical, coal, modifiers and emulsifiers, and the downstream is highways, waterproof building materials, airport construction and municipal engineering road construction. Now my country's asphalt industry has entered a stage of rapid development of scale and centralization, and people are becoming more and more familiar with asphalt, because the amount of asphalt i...

Problems solved by technology

This kind of molding machine has a complicated process and unsatisfactory molding effect. The molding is generally long and has irregular particle shapes. The degree of crushing is high, the production site is dusty, and the working environment for workers is harsh.

The overall equipment cost is high, and the conveying steel mesh as the main part of the forming machine has high operation and maintenance costs, which brings considerable cost pressure to the production and operation of the enterprise
