High-temperature-resistant and wear-resistant large kiln rotary kiln riding wheel assembly

Abstract

The invention relates to the technical field of rotary kiln riding wheels, and discloses a high-temperature-resistant and wear-resistant large kiln rotary kiln riding wheel assembly which comprises a flow guide box. An overflow groove is fixedly connected to the interior of the flow guide box, overflow holes are formed in the top of the overflow groove, and a base is fixedly connected to the top of the interior of the overflow groove. The inner wall of the base is movably connected with a rotating rod, the outer part of the rotating rod is fixedly in cup joint with stirring paddles, and the outer surface of the rotating rod is in meshed connection with a hinge. Cooling liquid is sprayed through cooling spray heads, the surface of a riding wheel is cooled, water is guided into a bottom refrigerating device through the overflow holes, the situation that the liquid level is too high, and a lubricating area of a rotating shaft in the riding wheel is damaged is avoided, meanwhile, the water is cooled through the refrigerating device, the water is guided into the overflow groove through a pump body, and the base is cooled; and the situations of short service life and high later maintenance cost caused by long-time working of the riding wheel and the base under a high-temperature condition are avoided.

Description

technical field [0001] The invention relates to the technical field of rotary kiln supporting wheels, in particular to a high temperature and wear-resistant large kiln rotary kiln supporting wheel assembly. Background technique [0002] Rotary kiln refers to rotary calcining kiln, which belongs to building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kiln is mainly used for calcining cement clinker. There are two types of cement kilns produced by the method, and the metallurgical chemical kiln is mainly used for the magnetization roasting of lean iron ore and the oxidation roasting of Inconel ore in iron and steel plants in the metallurgical industry. [0003] When the rotary kiln is in normal operation, the kiln body heats up, and the external temperature of the kiln body often exceeds 300C. The belt position of the rotary kiln body needs to be in constant contact with th...
