Description

Crushing apparatus based on tar sediment is retrieved usefulness

Technical Field

The utility model relates to the technical field of tar residue crushing treatment, in particular to crushing equipment for recycling tar residue.

Background

The tar residue is a viscous industrial solid dangerous waste produced in the coking production process, and the main components of the tar residue are substances such as coal dust, coke powder, graphite, heavy tar and the like. The tar residue needs to be crushed during recovery treatment. In the prior art, the crushing operation of tar residues is generally as follows: putting the tar residues into a pulverizer for pulverizing, wherein the tar residues after primary pulverization are often not thorough enough, and the larger tar residues which are not completely pulverized are manually collected again and poured into a pulverizing box for secondary pulverization and even three times of pulverization until the pulverization is complete.

Therefore, when the existing pulverizer is used for pulverizing and treating the tar residues, the tar residues cannot be completely pulverized at one time, the pulverizing effect is poor, and the tar residues which are not completely pulverized are fed back into the pulverizer to be pulverized again by manual cooperation, so that the existing tar residue pulverizing and treating work is time-consuming and labor-consuming, and the efficiency is low.
