Description

Technical Field

[0001] This utility model relates to the field of sintering furnace exhaust technology, and in particular to a centralized exhaust channel for a metal sintering furnace. Background Technology

[0002] A centralized exhaust channel for a metal sintering furnace refers to an exhaust system installed inside the sintering furnace. A centralized exhaust channel is usually designed as one or more channels located at the top or side of the furnace body and connected to an external exhaust system. It is used to effectively remove waste gas and harmful gases generated inside the furnace, ensuring safety and environmental protection.

[0003] The existing centralized exhaust system transports exhaust gas from the metal sintering furnace to the main exhaust pipe via branch exhaust pipes. Harmful gases in the exhaust gas are filtered through a filter plate inside the main exhaust pipe to meet emission standards. However, the filter plate's filtration efficiency decreases with prolonged use, requiring replacement. Since the filter plate is a single, integrated structure, replacement necessitates entry into the pipeline for complete disassembly, which is cumbersome and unsafe. Therefore, this solution proposes a centralized exhaust system for the metal sintering furnace to address these issues. Utility Model Content
