Abstract
The invention discloses an electrolytic aluminum anode production line heating system and an intelligent control system thereof, and the system comprises an asphalt receiving, storing and conveying thermal insulation system, a preheating spiral dry material heating system and an under-enthalpy water mixer which are sequentially arranged on a main steam pipeline, the preheating spiral dry material heating system is used for heating heat-conducting oil, the kneading machine dry material heating system is connected with the preheating spiral dry material heating system, the heat-conducting oil closed operation collecting system is connected with the kneading machine dry material heating system, and the preheating spiral dry material heating system and the kneading machine dry material heating system adopt medium-temperature medium-pressure steam to heat the heat-conducting oil. The asphalt receiving, storing and conveying thermal insulation system adopts medium-temperature and low-pressure steam for heating; according to the invention, under the condition that the kneading machine and the premixing spiral production line in the production workshop are not replaced, the steam is adopted to indirectly heat the dry materials in the kneading machine and the premixing spiral equipment, and an original heat conduction oil open system is changed into a closed system, so that the purposes of meeting the safety production requirement and increasing the yield and the efficiency can be achieved.
