Technical Field

[0001] The utility model relates to the technical field of flue gas purification, in particular to a flue gas purification device for steel slag processing equipment. Background Art

[0002] A large amount of harmful smoke is emitted during the processing of steel slag, so a purification device is needed to purify the smoke before discharging it into the atmosphere. Most of the existing purification devices draw the smoke into a filter box through a smoke exhaust fan, and purify the smoke through various purification layers in the filter box. Although the smoke can be purified, some of the dust in the smoke will stick to the inner wall of the filter box and is difficult to clean. The staff needs to disassemble the filter box for cleaning. The process is complicated and the cleaning efficiency is low. Utility Model Content

[0003] In view of this, the utility model provides a fume purification device for slag processing equipment, which can quickly clean dust, has a simple cleaning process and high cleaning efficiency.

When the grinding mill body is working, the steel slag is ground, and the vacuum pump draws the smoke from the grinding mill body into the filter cartridge, which is purified by the purification mechanism. The smoke is purified through the filter plate and then discharged through the air vents at the upper end of the filter cartridge. When the smoke adheres to the inner wall of the filter cartridge, the screw rod is rotated to drive the fixing plate to rotate and move downward, and the fixing plate drives the limiting column and the fixing column to move synchronously, so that the fixing column drives the fixing rod and the fixing plate to move synchronously, and the fixing plate drives the sponge pad to rotate and descend, so that the sponge pad cleans the smoke on the inner wall of the filter cartridge, thereby quickly cleaning the dust, and the cleaning process is simple with high cleaning efficiency.

[0005] The outer wall of the upper end of the filter cover is provided with an external threaded surface, the inner wall of the lower end of the filter cartridge is provided with an internal threaded surface, and the internal thread cotton at the lower end of the filter cartridge is threadedly connected with the external threaded surface at the upper end of the filter cover.
