Description
Technical Field
[0001] This utility model belongs to the field of electric furnace dust removal technology, and in particular relates to a dust removal device for a medium-frequency induction electric furnace used in casting. Background Technology
[0002] In casting production, medium-frequency induction furnaces are the core equipment for metal smelting. However, they generate a large amount of dusty waste gas during operation. If not treated in time, they will not only pollute the workshop environment and endanger the health of operators, but may also affect the service life of the equipment and the quality of the castings.
[0003] Dust removal devices for medium-frequency induction furnaces used in casting are specifically designed to solve this problem, achieving efficient dust collection and compliant emissions. They are key equipment for environmental protection and safe production in casting workshops. However, after filtering exhaust gas for a long time, existing furnace dust removal devices accumulate a large amount of particulate matter on the filter plates. If this is not cleaned in time, it can easily clog the filter holes, which will not only reduce filtration efficiency but also increase the internal pressure of the pipeline and cause safety accidents. Therefore, we have proposed a dust removal device for medium-frequency induction furnaces used in casting. Utility Model Content

By setting up a cleaning mechanism, specifically through high-speed linear reciprocating movement in coordination with springs, vibration and impact are generated to remove impurities from the filter plate. The removed impurities slide along the filter plate into the collection box, which can remove the attached matter from the filter plate in a timely manner. This not only improves the filtration efficiency but also reduces the probability of safety accidents caused by particulate matter blockage. It solves the problem that existing filter plates will have a large amount of particulate matter attached to them, which can easily block the filter holes if not cleaned in time, reducing filtration efficiency and increasing the internal pressure of the pipeline, thus causing safety accidents.
