TECHNICAL FIELD
[0001] The present application relates to the technical field of refractory processing, in particular to a lime intelligent batching system. BACKGROUND
[0002] Lime is the general term for quicklime and slaked lime, and its main components are (CaO) and magnesium oxide (MgO). The digestion of quicklime is an important link in construction mixing, and its process should be effectively controlled in specific construction. These two substances play a decisive role in the strength of the lime-fly ash base, especially after the hydration reaction with fly ash, the content of which has a more significant impact. Increasing the lime dosage within a certain limit can naturally increase the strength of lime-fly ash, but this not only increases the construction cost, but also is very detrimental to the crack resistance of the lime-fly ash base. Therefore, lime with high effective content should be selected as much as possible. Generally, lime must meet the standard of more than two grades, that is, the content of effective calcium and magnesium oxide in lime is not less than 80%. This can not only meet the needs of oxidation and hydration of lime-fly ash base to ensure the strength of the base, but also improve the stability of the base without affecting its crack resistance, which is very beneficial to the quality of the base. In the metallurgical lime production process in the refractory industry field, the finished product is 0-3mm powder active lime and 40mm or more block lime. The 0-3mm powder active lime is sent to the sintering plant by tank car, and the 40mm or more block lime is transported to the steelmaking process. The by-products in the lime production process (raw material limestone undersize waste, and dust removal ash collected by raw material dust remover, finished product dust remover, and main flue gas dust remover) are powder and granular waste. Most production plants provide by-products to sintering.
[0003] However, the tank car loading and discharging process causes serious environmental pollution and high transportation cost, and the added value is high, the recycling value is low, and some production plants also discharge by-products as waste or sell them to processing plants at a low price, which also causes environmental pollution and resource waste.
[0004] In view of the above situation, a new type of lime intelligent batching system is urgently needed to develop, which can save energy and improve the yield. The by-products in the lime production process (raw material undersize, raw material dust removal ash, flue gas dust removal ash, and finished product dust removal ash) are accurately controlled by the intelligent metering system. Under the premise of meeting the activity and other indicators of the finished product lime required by sintering, the qualified finished product is formed by proportioning. After mixing by technical means, it is transported to the sintering workshop by pneumatic conveying method, so as to achieve the effect of optimizing and reasonably utilizing resources. SUMMARY
