Description

Technical Field

[0001] The present invention relates to the technical field of coke production, in particular to a type I rotary drum device for coke post-reaction testing and a working method thereof. Background Art

[0002] According to the national standard GB / T400, "Test Method for Coke Reactivity and Post-Reaction Strength," a Type I rotary drum apparatus is required for measuring coke reactivity and post-reaction strength. Typically, a rotary drum consists of a frame, a reduction system, a feed system, a discharge system, and a control system. During the test, a coke sample of a specified mass is weighed and placed in a reactor. After reacting with carbon dioxide at 1100±5°C for two hours, the post-reaction coke strength is measured. The percentage of coke particles larger than 10 mm in size after the Type I rotary drum test represents the post-reaction strength. Currently, the post-reaction strength of coke is measured manually, requiring manual loading, sampling, and measurement. This process is labor-intensive, creates a poor working environment, and lacks automated control. Long-term loading and unloading of the drum requires frequent tightening and loosening of the bolts securing the drum to the frame, which can easily cause the drum cover to slip, hindering its opening and closing. The drum body is typically made of seamless steel pipe. It's typically 700mm long, 140mm in outer diameter, 5-6mm thick, and weighs 17kg. Loading and unloading the drum requires considerable physical strength, making it labor-intensive. Furthermore, the existing drum's inlet is directly covered by a drum cover, which requires manual tightening and opening during loading and unloading. This can cause dust to fly outward, which is detrimental to the operator's health. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a type I drum device and a working method for coke post-reaction testing. The present invention is based on automatic control means and can cooperate with a robot to realize automatic operation of the entire drum detection process.
