A kind of coal tar pitch preparation and processing method

Abstract

The invention relates to a method for preparing and processing coal tar pitch, comprising a workbench, a heating device and a stirring device. A heating device is fixedly installed on the upper end of the workbench, and a stirring device is fixedly installed in the middle of the heating device. The heating device includes a heating tank, Feed funnel, feed pipe, heat conduction rod, grinding frame 1, filter plate, discharge pipe, drop pipe and collection tank, the present invention cooperates with heating device and stirring device, coal slag is broken and ground, thereby make coal slag and The extraction liquid is fully contacted to improve the production utilization rate of the cinder, and at the same time accelerate the speed of solid-liquid separation and reduce the time spent on production. Reduced in order to fully heat the cinder.

Description

technical field [0001] The invention relates to the field of asphalt processing, in particular to a method for preparing and processing coal tar pitch. Background technique [0002] Bitumen 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 mostly exists in the form of liquid or semi-solid petroleum. The surface is black and soluble in Carbon disulfide, carbon tetrachloride, and asphalt are organic gelling materials that are waterproof, moisture-proof and anti-corrosion. Asphalt can be mainly divided into three types: coal tar pitch, petroleum pitch and natural asphalt. Asphalt is mainly used in coatings, plastics, rubber and other industries. Pave the road. [0003] In the process of preparing and processing asphalt, due to the quality requirements of cinder raw materials and asphalt, the following problems exist in the actual operation process: [00...

AI Technical Summary

Problems solved by technology

[0004] (1) During the preparation process of coal tar pitch, generally only the cinders are crushed and stirred, and it is difficult to completely mix the cinders with the extraction solution evenly, resulting in a low liquid content during solid-liquid separation, resulting in a low production utilization rate of cinders, thereby improving The amount of cinder raw material consumed for processing

[0005] (2) During the preparation of coal tar pitch, the temperature of each part of the cinder is greatly different during the heating process. When it is stirred, the cinder with a lower temperature needs to be stirred to the outside for many times to contact the heating parts, so that Cinders are fully heated, resulting in increased time spent on preparation and processing
