AI Technical Summary
During the spheroidizing process, existing technologies directly smoke and exhaust dust above the spheroidizing furnace, causing the molten iron to cool down too quickly, which is not suitable for subsequent processes.
Design a cooling and dust removal device for a spheroidizing furnace, including a dust collection hood, dust removal pipe, baffle and nozzle. The device removes dust through water mist spraying and filter cloth filtration, avoiding direct absorption of flue gas which would cause the molten iron to cool down too quickly.
This achieves rapid dust removal while preventing the molten iron from cooling down too quickly, thus meeting the requirements of subsequent processes.

TECHNICAL FIELD
[0001] The utility model belongs to the field of exhaust equipment, and particularly relates to a spheroidizing furnace cooling and smoke dust removing device. BACKGROUND
[0002] The gray pig iron and the scrap steel are mixed according to a certain proportion, are melted through the intermediate frequency furnace, are added with spheroidizing agent and react with the molten iron to obtain the nodular iron with required performance, and the nodular iron is an important process for producing nodular iron castings. However, in the spheroidizing process, a large amount of smoke dust is generated due to the violent reaction; the original dust removal method is to directly suck smoke and remove dust above the spheroidizing ladle, and the dust removal has the advantages of simplicity and quickness, and the disadvantage is that the molten iron is cooled too much, and the method is not suitable for the subsequent process. CONTENT OF THE UTILITY MODEL
[0003] In order to solve the above technical problems, the utility model provides a spheroidizing furnace cooling and smoke dust removing device, which comprises a spheroidizing furnace, a dust removal pipe and a dust collecting hood, the dust collecting hood is arranged above the spheroidizing furnace, the upper end of the dust collecting hood is connected with the lower end of the dust removal pipe, baffles one and two are arranged in the dust collecting hood, the side wall of the baffle one is provided with a connecting rod, the connecting rod is fixedly connected with the lower part of the dust collecting hood, the baffle two is fixedly connected with the upper part of the dust collecting hood, the middle part of the baffle two is provided with filter cloth, and a fan is arranged in the dust removal pipe.
[0004] Further, the lower side of the edge of the baffle two is connected with a plurality of spray heads, a water tank is arranged outside the dust collecting hood, the tail part of the spray head is provided with a hose, the hose is communicated with the water tank, the spray head sprays water mist, and is used for adsorbing dust in the air.
[0005] Further, a dehumidification layer is arranged on the inner side of the dust removal pipe, the dehumidification layer adopts dehumidification filter cloth, and is used for removing water in the air.
[0006] Further, the baffle one is concave-shaped and the concave surface faces upwards, is used for collecting dust filtered by the filter cloth, and avoids that the dust collecting hood directly sucks away smoke gas above the spheroidizing furnace, so that the molten iron is cooled too fast.
[0007] The utility model also comprises other devices or components capable of enabling the spheroidizing furnace cooling and smoke dust removing device to be normally used, and all are conventional technical means in the field. In addition, the spheroidizing furnace and the dust collecting hood not limited in the utility model adopt conventional technical means in the field.
[0008] The working principle of the utility model is that when the device extracts and discharges smoke gas, the smoke gas is sucked into the gap between the baffle one and the dust collecting hood, dust in the smoke gas is removed through water mist spraying, water drops generated by the water mist are collected on the upper side of the baffle one, most impurities in the smoke gas are filtered through the filter cloth, water in the smoke gas is reduced through the dehumidification filter cloth, and the remaining gas is discharged through the dust removal pipe.
[0009] The device avoids that the dust collecting cover directly sucks away the flue gas above the spheroidizing furnace, causes the molten iron to be cooled too fast, and the water mist is sprayed to adsorb the smoke dust, and the treated gas is discharged, so that the rapid dust removal is met, and the molten iron is prevented from being cooled too fast due to the exhaust. BRIEF DESCRIPTION OF DRAWINGS
