An integrated wheel belt and a ribbed wall surface spray drum cooler containing it

Abstract

The invention discloses an integrated wheel belt and a ribbed wall face spraying drum cooling machine comprising the same. The integrated wheel belt comprises a wheel belt and a force transmission ring. The ribbed wall face spraying drum cooling machine comprises the integrated wheel belt, and further comprises a feeding unit, a rotary cylinder unit and a discharging unit; and the integrated wheelbelt is arranged between an inner cylinder body and an outer cylinder body, an overall floating type liner is arranged in a double-layer cylinder of a front-end cylinder, and ribs are arranged between the inner cylinder body and the outer cylinder body of the double-layer cylinder as well as arranged on the outer wall face of a quick cooling section cylinder. According to the integrated wheel belt and the ribbed wall face spraying drum cooling machine comprising the same, the heat exchange efficiency is improved, the problems existing in an original system are solved, the equipment size and the running cost are further reduced, the working efficiency and the reliability of equipment are improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of metallurgy and mining, in particular to an integrated wheel belt for cooling reduced iron pellets and sintered pellets and a ribbed wall surface spray drum cooler containing the same. Background technique [0002] Cooling is one of the important processes in calcining reduced iron engineering. The temperature at the outlet of the direct reduced iron pellets passing through the rotary hearth furnace or rotary kiln is usually as high as 1100°C. The pellets enter the cylinder of the cooling machine through the chute. During the rotation of the cylinder with an inclination angle, the material flows from the inlet to the outlet sports. [0003] The Chinese patent application number 201010029029.4 discloses a "reduced iron high-efficiency spray rotary drum cooler". The technical solution of this patent is: 1) adopt spray cooling method, and the outer wall of the cylinder is covered with spray to improve cooli...

AI Technical Summary

Problems solved by technology

[0004] (1) The connection method of the double-layer cylinder is complicated, and long-term work will easily lead to serious wear and tear of the connection and poor reliability

[0005] (2) The phenomenon of biting or slipping easily occurs between the wheel belt and the backing plate at the support, and abnormal rolling displacement occurs, causing abnormal friction between the backing plate and the wheel belt. Regular maintenance and replacement of the backing plate are required

[0006] (3) A number of lining plates are used on the inner surface of the inner cylinder at the front end, which are connected by bolts or welded. The reliability is not high, it is easy to fall off, the heat transfer efficiency is low, and the maintenance workload is large
