Description

Technical Field

[0001] This utility model belongs to the field of lead smelting technology, and in particular relates to a smoke and splash prevention device for lead smelting. Background Technology

[0002] Lead smelting refers to the process of extracting lead metal by heating and melting lead-containing ore. During lead smelting, fumes and waste are generated. In order to reduce the damage of lead-containing fumes to the working environment and to prevent waste from splashing and injuring workers, appropriate smoke and splash prevention components need to be installed on the lead smelting equipment. The lead-containing fumes are introduced into the purification device for purification treatment before being discharged, and waste splashing is prevented.

[0003] A search revealed a smoke and splash prevention device for lead smelting, disclosed in patent publication number CN214065755U. The device includes a base, a smelting tank and a support frame mounted on the base, a smelting apparatus mounted on the smelting tank, and an iron cover covering the smelting apparatus. Several small holes are opened on one side of the iron cover, and a lead guide opening is provided on the other side. A smoke extractor is installed near the small holes. A first hanging ring is installed at the bottom of the iron cover, and a rectangular hanging lug is provided on the iron cover. A second hanging ring is provided at the top of the iron cover, and a third hanging ring is fitted onto the second hanging ring. A buckle device is installed at the opening of the third hanging ring, and the third hanging ring is connected to the support frame via a telescopic rod. This device can prevent fumes generated during smelting from polluting the environment and causing injury to workers, prevent the second hanging ring from falling off and damaging the outer cover, and allows for diverse control of the iron cover.

[0004] The aforementioned smoke and splash prevention device for lead smelting includes a smelting apparatus installed on a smelting tank. The smelting apparatus is covered by an iron cover. One side of the iron cover has several small holes, and the other side has a lead guide port. A smoke extractor is installed near the small holes and fixed to a support frame. A first, square, upturned hanging ring with a circular through hole is installed along the bottom edge of the iron cover. Rectangular hanging ears are provided on the iron cover. However, the iron cover only has openings at the bottom, making cleaning the inner wall inconvenient. A second hanging ring is located at the top of the iron cover, and a third hanging ring is fitted onto the second hanging ring. A buckle device is installed at the opening of the third hanging ring, and the third hanging ring is connected to the support frame via a telescopic rod. The buckle device includes a buckle holder with a buckle groove. A buckle pin extends into the buckle groove and has a first through hole. The buckle groove has a second and a third through hole. A fourth through hole is provided on the side of the bracket near the slot; bolts pass through the second, first, third, and fourth through holes in sequence, and nuts are screwed on both ends of the bolts to fix them. The outer cover is hung on the support frame by the second and third hanging rings. The third hanging ring is opened and closed by a buckle device. Bolts pass through the second, first, third, and fourth through holes in sequence, and nuts are screwed on both ends of the bolts to fix them to close the third hanging ring. By unscrewing the nuts at both ends of the bolts and pulling out the bolts, the opening of the third hanging ring is opened. The telescopic rod extends and retracts to change the height of the iron cover. When the telescopic rod is not working, the iron cover can be raised and lowered by threading a rope through the hanging lug or the first hanging ring and pulling the rope. However, during the up and down movement of the iron cover, the position of the iron cover is not stable enough, causing the iron cover to sway during the up and down movement, reducing the stability of the iron cover during movement.
