Description

Technical Field

[0001] The utility model belongs to the technical field of graphitization processing, and in particular relates to a furnace dust collection device applied to a graphitization furnace. Background Art

[0002] In order to obtain high electrical conductivity, high thermal conductivity, corrosion resistance, friction resistance and other properties of graphite, the raw materials need to be placed in a graphitization furnace and heated at high temperature to make it undergo a graphitization reaction. Most methods use a graphitization furnace to graphitize the carbon blank, that is, the raw materials are directly loaded into a rectangular furnace body constructed of refractory materials to form a conductive furnace core. Conductive electrodes are provided on the two walls of the furnace head and connected to a power source to form an energized circuit. When the circuit is connected, the furnace core generates heat and heats up due to the action of resistance, so that the raw materials can be graphitized at high temperature.

[0003] According to patent No. CN201920772326.4, a furnace loading dust collection device used for a graphitization furnace includes a pressing device, an exhaust fan, a connecting seat, a dust collection hood, a dust collection pipe, a dust collection box, a stop valve, a breathable bag, a hanging ring, and an air intake pipe. The mechanism uses a pressing device to compact the carbon blank during the loading process of the graphitization furnace, and uses a dust collection device to adsorb and recycle the graphite dust generated during the compaction process.

[0004] The above scheme still has certain technical defects in actual use. When graphite dust passes through the breathable bag, smaller graphite dust particles will still pass through the breathable bag and diffuse to the outside, resulting in a decrease in the efficiency of dust collection. In addition, the collection efficiency of the dust box for graphite dust is not high. A large amount of dust will be sucked out by the exhaust fan after passing through the dust box, resulting in a decrease in dust collection efficiency. For this reason, we propose a furnace dust collection device for a graphitization furnace. Utility Model Content

By arranging a rubber sleeve 6 on the periphery of the extension block 9 and the collection box 5, the sealing performance is improved to avoid leakage, thereby ensuring the stability of the filtering and collecting effects.
