Description

Technical Field

[0001] This utility model belongs to the field of calcium carbide production technology, and specifically relates to a lime powder pelletizing device for calcium carbide production. Background Technology

[0002] The calcium carbide production process has specific requirements for the particle size of raw materials entering the furnace. Lime must be screened before entering the furnace. Approximately 0.92 tons of lime with a particle size of 20-70mm are needed per ton of calcium carbide to ensure the safe, stable, high-quality, and high-yield operation of the calcium carbide furnace. To reduce lime consumption without affecting the safe and stable operation of the furnace, the original 5mm*10*20mm comb-shaped screen was replaced with a combination of a φ5mm round hole screen and a 5mm*10*20mm comb-shaped screen to reduce lime powder. However, the amount of lime powder still accounts for 10%-15% of the total lime content. Because the lime powder particle size is too small to be used in the calcium carbide process, it can only be treated as waste and sold at a low price.

[0003] Currently, calcium carbide production faces two problems: first, the lime powder is sold at low prices to other countries; second, dust is generated during the export process, causing environmental pollution. Utility Model Content

[0015] In this embodiment, the finished lime produced by the lime kiln 1 is conveyed to the calcium carbide furnace 11 via conveyor belt 12 for calcium carbide processing. The dust collector 2 sucks up the lime powder produced by the lime kiln 1 and conveys it to the lime pelletizing silo 10 via conveyor pipe 3.

The lime pellets are used in calcium carbide production. The collection component 7 collects the lime powder remaining after processing by the high-pressure briquetting machine 9 and conveys it to the lime pelletizing silo 10. The lime pellets are tested by the detection component 8. Qualified lime pellets are conveyed to the calcium carbide furnace hopper. The corresponding amount of lime pellets is added to the calcium carbide furnace 11 according to processing requirements. Unqualified lime pellets are discarded. The lime balls are conveyed to the lime briquetting silo 10. The lime balls are added to the screening plate 81 and guided through the guide chute 88. The detection camera 87 checks the integrity of the lime balls. An electric telescopic rod 832 extends, moving the baffle 834, which inserts into the slot 835, intercepting unqualified lime balls. An electric telescopic rod 894 retracts, causing the partition 892 to move downwards. The lime balls at the top of the partition 892 fall from the waste chute 810 into the waste collection chute 84. Qualified lime balls fall through the guide chute 88 into the good material collection chute 85, achieving rapid screening and improving detection efficiency. An air pump 74 draws air, which is then diverted through the diverter 76 and sprayed from the nozzle 75. A suction pump 73 operates, causing the collection hood 71 to draw in residual lime powder from the high-pressure briquetting machine 9. This powder is then conveyed through the conveying pipe 72 to the lime briquetting silo 10 for collection and reuse, improving the utilization rate of lime.
