Application and improvement of energy saving of sealed steel brush

Waste heat utilization is an important aspect of sintering energy saving. At present, many domestic sintering plants have built waste heat power generation systems. Originally, waste heat power generation is a mature technology, but there is a phenomenon of large and low efficiency in practical application. There are two main reasons: first, the waste gas is not well recycled; Second, the air leakage of the system causes the low temperature of the exhaust gas from the cooler, which is difficult to recover, and the utilization efficiency of waste heat is low.

The flexible magnetic seal of the ring cooler is a new technology developed to solve the air leakage of the ring cooler. Its sealing method can greatly reduce the air leakage, on-site dust and noise, and improve the efficiency of waste heat power generation. The utility model relates to a flexible compensation sealing system of a ring cooler. The root of the dynamic sealing brush is fixed on the dynamic sealing frame, and the brush tip of the dynamic sealing brush is on the contact surface of the ring cooler frame, which is in damping sealing contact with the contact surface of the ring cooler frame; The root of the flexible guide device is fixed on the sealing compensation device, which is fixed on the framework of the ring cooler through the connecting device; The brush tip of the flexible guide device is on the sealing panel at the bottom of the trolley and is in damping sealing contact with the sealing panel at the bottom of the trolley. By adopting the utility model, the harmful air leakage of the ring cooler is significantly reduced, the cooling is improved, the phenomenon of "red ore running" can be eliminated, and the passive situation in the previous production is improved, so that: 1. The belt loss is greatly reduced and the operation rate of the sintering machine is improved. 2. The sealing system does not need frequent maintenance and replacement. 3. Reduce power consumption. 4. The environment is protected, which greatly reduces the maintenance cost and human resources.
