Description

Technical Field

[0001] This invention relates to the field of cement mortar production technology, specifically to a production line for preparing low-carbon cement mortar from composite nickel-iron slag powder. Background Technology

[0002] With the deepening of the low-carbon economy concept, the building materials industry has an increasingly urgent need for the resource utilization of industrial solid waste. Nickel-iron slag, as an industrial waste generated during the production of nickel-iron alloys, generates a huge amount of emissions. Direct dumping of this waste not only occupies a large amount of land resources but also pollutes soil and water resources due to the seepage of harmful substances contained in the waste. Grinding nickel-iron slag and using it to prepare low-carbon cement mortar can both realize the resource utilization of solid waste and reduce carbon emissions during cement production, which aligns with the trend of green building materials development.

[0003] Existing production lines for preparing cement mortar from nickel-iron slag powder generally suffer from problems such as low crushing efficiency, poor screening effect, and inconvenience in recycling unqualified materials. Traditional crushers are mostly single-stage crushing structures, which are insufficient to crush nickel-iron slag to the fineness required for cement mortar preparation. Furthermore, the crushed material is not thoroughly screened, and large particles mixed in can affect the strength and performance of the cement mortar. At the same time, the crushing, separating, and conveying equipment in existing production lines are mostly independently driven, resulting in poor coordination between the equipment, low production efficiency, and high energy consumption, making it difficult to meet the needs of large-scale low-carbon production.

[0004] To address the shortcomings of the existing technologies, this invention proposes a production line for preparing low-carbon cement mortar from composite nickel-iron slag powder. By optimizing the equipment structure design, it achieves integrated operation of crushing, separation, and material lifting, thereby improving the crushing and screening effect and material recycling rate, reducing production energy consumption, and ensuring the production quality and efficiency of low-carbon cement mortar.

[0035] Working principle: First, the nickel-iron slag raw material is put into the feed hopper 11 of the crusher 1. The external drive motor is started and drives the crushing drive shaft 126 of the crusher 1 and the main drive shaft 22 of the separator 2 to rotate through the first transmission belt 1262. The moving tooth plate 1253 in the crusher 1 drives the moving tooth 1254 to cooperate with the fixed tooth 1131 to crush the nickel-iron slag.

[0036] Then, the crushed material falls into the screening hopper 214 of the separator 2 for preliminary screening. The unqualified material after preliminary screening is collected at the bottom of the screening hopper 214 and enters the feed pipe 211. It falls into the lifting machine 3 through the feed pipe 211 and is lifted by the crusher 3 and put back into the feed hopper 11 of the crusher 1 for further crushing.

[0037] Meanwhile, the crushed and qualified material falls through the fine sieve holes on the sieve hopper 214, and after being guided by the first guide plate 215 and the second guide plate 216, it falls onto the magnetic separation roller 223. The magnetic separation roller 223 adsorbs ferromagnetic impurities in the material, and the scraper 217 scrapes off the impurities. The material after removing the impurities falls onto the diversion plate 218. The qualified material enters the discharge pipe 212 through the first discharge port 2181 and is conveyed out by the spiral plate 243 on the discharge shaft 24 for subsequent preparation of low-carbon cement mortar. The unqualified material is discharged from the separator 2 through the first discharge port 2181.

[0038] Throughout the process, the crusher 1, separator 2 and conveyor 3 work together through a transmission connection, eliminating the need for multiple independent drive sources, resulting in low energy consumption and high production efficiency.
