Problems solved by technology
[0003] The following problems often exist in the process of processing steelmaking slag: 1. Since the steelmaking slag is often piled up and preheated, it is not conducive to subsequent processing, so it needs to be cooled before grinding, but the piled up Second, because part of the steelmaking slag is too round, it is difficult to be ground and unloaded by the grinding device during the grinding process, resulting in the accumulation of steelmaking slag at the grinding position, affecting work efficiency

Embodiment Construction
[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0025] Such as Figure 1 to Figure 5 The shown environmental protection treatment system for iron and steel smelting slag includes a processing cylinder 1, a humidity-adjusting and spreading device 2 and a grinding and drying device 3. The milling and drying device 3 is arranged on the inner wall of the lower end of the processing cylinder 1; the humidity regulating and distributing device 2 spreads the steelmaking slag, adjusts the humidity and lowers the temperature, and then the steelmaking slag is ground and dried by the milling and drying device 3 .
[0026] Described humidity control spreading device 2 comprises feeding port 21, drive motor 22, rotating shaft 23, unloading trough plate 24, spreading mechanism 25, rotating gear cylinder 26, rot...

The invention relates to an environmental protection treatment system for iron and steel smelting slag, which comprises a treatment cylinder, a humidity control and spreading device and a grinding and drying device. On the inner wall of the lower end of the treatment cylinder; the present invention solves the problem that the stacked steelmaking slag is not good for heat dissipation by spreading the stacked slag, and by adding moisture, the internal waste heat is exported; The drying hot air can not only assist the unloading of the steelmaking slag from the grinding position, but also remove the water cooled in the previous step, thereby preventing the water from acting as a lubricant during the grinding process; The operation of the equipment is realized, and the cost is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of iron and steel smelting production, in particular to an environmental protection treatment system for iron and steel smelting slag. Background technique [0002] Steelmaking slag refers to the general term for the products formed by the physical and chemical reaction of the oxides formed by the impurities in the metal material in the steelmaking process by the oxidation of the oxidant and then with the slagging agent and the furnace lining. Slag has a lower density than molten steel and usually covers the surface of molten steel. The main task of steelmaking is to remove harmful impurities in molten steel to the greatest extent. The application value of steel slag is very great, mainly including: recycling of scrap steel, application in steel production, steel slag cement production, road engineering and building filling, and steel slag phosphate fertilizer. [0003] The following problems often exist i...
