Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology for smelting furnaces, specifically referring to a dust removal device for smelting furnaces. Background Technology

[0002] A smelting furnace is a furnace used to melt iron ore, such as hematite or magnetite, to produce pig iron. This type of furnace is a tall, columnar structure lined with refractory materials, filled from the top with washed ore, coke, and a solvent (usually limestone). Since smelting furnaces produce a significant amount of dusty exhaust gas, dust removal is essential to ensure its safe emission.

[0003] In the existing technology, dust removal in smelting furnaces requires covering the furnace opening with a dust collection hood. However, the dust collection hood on the top inner wall of the smelting furnace can easily cover the smoke and dust emitted from the furnace, causing the smoke and dust to accumulate on the inner wall. This affects the dust collection hood's ability to collect smoke and dust from the furnace opening and also affects the durability of the dust collection hood. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a dust removal device for smelting furnaces, so as to at least partially solve the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0015] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0016] like Figures 1-5 As shown in the figure, this utility model provides a dust removal device, particularly a dust removal device for a smelting furnace, including a dust collection hood 1, a cleaning section 2, a filter plate 3, a dust collection ring 4, a dust collection area 5, a cleaning scraper 6, a dust guide bracket 7, and a conveying area 8, as shown. Figure 1 As shown, the dust collection hood 1 covers the smelting furnace. The fumes generated by the smelting furnace drift out from the furnace opening. A gas supply pipe 9 is fixedly connected to the top of the dust collection hood 1. The other end of the gas supply pipe 9 is connected to a negative pressure dust collector 10. The suction force generated by the negative pressure dust collector 10 draws the fumes generated by the smelting furnace away through the dust collection hood 1, and then through the gas supply pipe 9 is drawn into the interior of the negative pressure dust collector 10.

[0017] In order to filter the flue gas from the smelting furnace, a filter plate 3 is installed inside the dust collection hood 1. The middle part of the filter plate 3 is concave upward, so that the dust attached to the bottom of the filter plate 3 can easily collect to the edge. A cleaning scraper 6 is rotatably connected to the bottom center of the filter plate 3. The top of the cleaning scraper 6 contacts the bottom of the filter plate 3 and the inner wall of the dust collection hood 1. By rotating the cleaning scraper 6, the flue gas attached to the bottom of the filter plate 3 and the inner wall of the dust collection hood 1 is hung off. To collect the scraped dust, a dust guide bracket 7 is fixedly connected to the bottom of the cleaning scraper 6. The top of the dust guide bracket 7 does not contact the filter plate 3 or the inner wall of the dust collection hood 1. The interior of the dust guide bracket 7 is divided into two conveying areas 8 by the cleaning scraper 6. The dust scraped off from the bottom of the filter plate 3 and the inner wall of the dust collection hood 1 by the cleaning scraper 6 falls into the interior of the conveying area 8. However, as the dust guide bracket 7 rotates with the cleaning scraper 6, the scraped dust is thrown outward. The dust guide bracket 7 tilts towards the edge with the bottom of the filter plate 3 and falls downward when it slides to the edge of the dust collection hood 1.

[0018] To collect the dust and powder scraped off, a detachable dust collection ring 4 is installed at the bottom of the dust collection hood 1. The bottom of the dust collection ring 4 is bent inward to form a dust collection area 5. The dust collection area 5 is used to collect the dust and powder scraped off by the cleaning scraper 6. To facilitate the disassembly of the dust collection ring 4, a locking collar 1101 is fixedly connected to the upper end of the outer wall of the dust collection ring 4. First locking blocks 1102 are fixedly connected to both sides of the bottom of the outer wall of the dust collection ring 4. The top two sides of the inner wall of the locking collar 1101 are fixedly connected to... The second locking block 1103 passes through the gap between the first locking block 1102 and contacts the bottom of the inner side of the locking collar 1101. When the second locking block 1103 is located above and in contact with the first locking block 1102, the dust collection ring 4 and the dust collection hood 1 are in a locked state. When the second locking block 1103 is located at the gap between the first locking block 1102, the dust collection ring 4 and the dust collection hood 1 are in an unlocked state. The locking mechanism 11 is used to disassemble and lock the dust collection ring 4 and the dust collection hood 1. This timely collection of dust and powder from the bottom of the filter plate 3 and the inner wall of the dust collection hood 1 prevents the filter plate 3 from becoming clogged and affecting the filtration effect.
