Abstract
The invention relates to a co-rotating type cooling drum, which is specially suitable for fast cooling of high-temperature sands in casting industry and belongs to the technical field of cooling device structures. The co-rotating type cooling drum is characterized by being formed by a power transmission system installed on a base, a drum driven by the power transmission system and a cooling device. A feeding device and a discharging device are respectively connected at two ends of the drum. The co-rotating type cooling drum is reasonable in design, and due to contact between hot sand and inner wall of an outer tube and cooling media filled outside the outer tube, the hot sand in the outer tube moves to a sand cavity in rolling mode and exchanges heat with the cooling media water outside the outer tube. Due to the fact that one screw pitch can be moved in rolling mode when the hot sand in a spiral groove of the outer tube turns for one round, the longer the cooling time is, the better the cooling effect is, and area of cooling water is large. Therefore, cooling is fast. Further, rotating speed of the hot sand can be controlled by a frequency converter according to cooling conditions, maintenance is convenient, service life is long, yield is high, power consumption is low, electricity is saved and the co-rotating type cooling drum has wide application prospect.
