Abstract

A progressive crushing device for petroleum coke, including a shearing and crushing mechanism and a crushing and crushing mechanism arranged up and down; the shearing and crushing mechanism includes two shearing and crushing rollers arranged side by side, and the two shearing and crushing rollers are driven by two motors Driven by two first rotating shafts respectively, several shearing and crushing teeth are evenly arranged on the shearing and crushing roller; a triangular prism-shaped shearing block is arranged on the shearing and crushing teeth, and the length direction of the shearing block is in line with the shearing and crushing The roller surface of the roller is tangent, and a triangular prism-shaped material distribution block is also arranged on the shearing and crushing teeth. The extrusion crushing mechanism includes two extrusion crushing rollers arranged side by side, and the two extrusion crushing rollers respectively follow the two second rotating shafts, and the two second rotating shafts are respectively connected with the two first rotating shafts through the transmission device and rotate synchronously , Several extrusion crushing teeth are evenly arranged on the peripheral side of the extrusion crushing roller. The present invention not only has a good crushing effect, but also can effectively prevent the petroleum coke from being stuck on the crushing roller.

Description

technical field

[0001] The invention relates to the field of petrochemical equipment, in particular to a progressive crushing device for petroleum coke. Background technique

[0002] Petroleum coke is a product obtained by distilling crude oil to separate light and heavy oils, and then thermally cracking the heavy oil. From the appearance, the coke is black lumps with irregular shapes and sizes, with metallic Gloss, the particles of coke have a porous structure, and the main element is carbon;

[0003] In the refining and chemical industry, delayed coking is a heavy oil deep processing technology that converts heavy oil into gas, light middle distillate oil and petroleum coke through deep thermal cracking. Low-level characteristics, it has become one of the important processes in heavy oil processing technology;

[0004] my country produces more than 10 million tons of petroleum coke every year. Decoking and transporting petroleum coke are an important part of the delayed ...
