Barrel of rotary water-spraying cooling device

Abstract

The invention relates to a barrel of a rotary water-spraying cooling device. The barrel comprises a cooling water nozzle, a water retaining plate, a water retaining hood, a barrel, wheel belts, wheel belt gaskets and a water cooling box. The wheel belts are arranged at two ends of the excircle of the barrel through the plurality of wheel belt gaskets, the water retaining hood is arranged at two sides of the wheel belts, the cooling water nozzle is mounted on the water inlet side of the water retaining hood, the water retaining plate is mounted on the other side of the water retaining hood, and the water cooling box is arranged below the barrel. The barrel provided by the invention is simple in structure and good in cooling effect, cooling water is recycled; the steel manufacture consumption, cost and energy power consumption can be reduced; the operating rate and reliability of equipment are improved, and the product quality is improved.

Description

technical field [0001] The invention belongs to the field of cylinder coolers in the metallurgical industry, and relates to a cylinder of a rotary water spray cooling device, which is mainly used for cooling reduced iron pellets and sintered pellets in the metallurgical and mining industry. Background technique [0002] The horizontal rotary drum cooler is one of the main equipment for cooling high-temperature reduced iron boiled pellets. After entering the cylinder of the cooling machine, the high-temperature reduced iron cooked balls are turned with the rotation of the cooling cylinder, and move from the feed end to the discharge end. At present, most steel companies use cooling water to directly spray the cylinder to achieve the cooling effect. The cooling section of the cylinder is usually only installed between the two supports of the cylinder for spray cooling. There is no cooling water protection at the belt of the cylinder support wheel, which will easily cause the d...

AI Technical Summary

Problems solved by technology

[0003] (1) The water vapor generated by the spray cooling used between the double-layer sleeves cannot be drained away, which seriously affects the cooling effect;

[0004] (2) The structure is very complex;

[0005] (3) The spray cooling water is easy to flow or seep into the cylinder, which will affect the reduction rate and pulverization rate of the reduced iron pellets;

[0007] (5) It is difficult to install, maintain and repair
