Inner and outer ring sealing aspects: in the actual production of the ring cooler equipment, the temperature of the high-temperature section is up to 1000 ℃, and the temperature of the low-temperature section is only about 100 ℃, because fine sand is used as a sealing medium between the fixed smoke hood and the revolving body, the heat conduction and heat dissipation performance of the ring cooler are poor, and the sand seal groove (made of common steel plates) needs to work alternately and continuously in a cold and hot state at the temperature of 100-1100 ℃ every time the ring cooler rotates, so that the deformation is easy to generate. Due to the penetration of hot air, the steel plate at one side of the sand seal groove, which is close to the rotary body of the annular cooler, is deformed firstly, the tightness is poor, and the hot air leaks out; in turn, the deformation and desoldering of the whole sand seal groove are aggravated, so that fine sand in the seal groove is blown away by hot air, and a large amount of high-temperature hot air and partial hot balls are extruded into the sand seal groove, so that the whole sand seal groove is deformed. In addition, the refractory material is easy to crack due to expansion with heat and contraction with cold, and can be broken and fall off when being scraped and bumped by external force. After the protection of refractory materials is lost, a fixed side plate (manufactured by a common steel plate) of the annular cooler is burnt and oxidized by high-temperature hot air, a rotary body is blocked, and finally the rotary body is forced to be shut down for maintenance, so that the shutdown maintenance caused by the loss of the protection of the refractory materials is very frequent, the workload is high, and the cost is high.
