Description

Technical Field

[0001] The present application relates to the technical field of fume collection in smelting furnaces, and in particular to a fume collection device that is easy to clean. Background Art

[0002] A smelting furnace refers to a processing equipment that melts metal ingots and some scrap metals and adds necessary alloy components, and then smelts them into the required alloy through various operations such as slagging and refining. A smelting furnace will produce a large amount of flue gas during use. In order to reduce the impact and pollution of the smelting furnace on the environment, a flue gas collection device is needed to collect the flue gas.

[0003] At present, a Chinese patent with announcement number CN215063795U discloses a smoke collection device, including a smoke pipe, an induced draft hood and a collection hood. There are multiple induced draft hoods, and they are all installed on the smoke pipe. A valve is arranged on the induced draft hood. The collection hood is connected to the smoke pipe through a movable device. The top of the collection hood is provided with an opening that is adapted to the shape and size of the lower end of the induced draft hood, so that the collection hood can form an air suction hood with any one of the induced draft hoods as a whole. The end of the smoke pipe is connected to the main smoke pipe, and the main smoke pipe is connected to the induced draft fan.

[0004] With respect to the above-mentioned related technologies, the inventors believe that during the use of the above-mentioned smoke collection device, the smoke is prone to carry a lot of smoke dust impurities. The smoke dust enters the smoke pipe and the inner wall of the hood along with the smoke, making it difficult to clean the inside.

[0047] After a period of smoke filtering, the cleaning rod 75 rotates to scrape off the dust adhering to the connecting edge 62 and the filter cartridge 61, reducing the possibility of clogging of the filter cartridge 61. When cleaning the filter cartridge 61, the closed valve plate 11 rotates to a horizontal position, and the back-blowing blower 16 is started to blow off the impurities on the filter cartridge 61, which helps to improve the cleaning effect of the filter cartridge 61. The smoke enters the gas delivery pipe 1, and the scraper 22 rotates to scrape off the impurities on the inner wall of the gas delivery pipe 1, and the impurities fall into the collection box 5.
