Background

The ring cooling machine is one of important equipment of sintering production technology, and is used for cooling high-temperature sinter, and the ring cooling machine is provided with a circular ring-shaped rotary body trolley, and the high-temperature sinter is uniformly distributed in an annular accommodating groove of the rotary trolley and runs around the center of the ring cooling machine along with the rotary body trolley, and cooling air blown by an air blower passes through the high-temperature sinter from the lower part of the rotary body trolley through an air box to exchange heat, so that the purpose of cooling the sinter is achieved by taking away heat through the cooling air, and for better recovering hot waste gas, sealing is performed between a baffle plate of the rotary body trolley and a smoke hood of the ring cooling machine. The liquid seal has better sealing effect than the traditional mechanical seal, and is widely used in the industry at present. The specific form is that a group of annular liquid tanks are arranged between a revolving body trolley breast board and an annular cooling machine smoke hood, and liquid, usually water, is filled in the liquid tanks. However, in the operation process of the ring cooling machine, the high-temperature waste gas in the smoke hood can cause the annular plate in the liquid tank to deform seriously, and further can cause the welding part of the liquid tank to crack, so that the leakage phenomenon occurs. Meanwhile, fine bulk materials and dust can inevitably enter the sealed liquid tank, and sludge can be formed at the bottom of the tank after a period of time accumulation, so that the sludge is extremely difficult to clean, and the normal operation of the ring cooling machine can be seriously influenced due to untimely cleaning. At present, steel enterprises generally adopt a high-temperature resistant rubber plate or a steel wire brush to be additionally arranged between a smoke hood and the top of a trolley breast board to solve the problem of complaint, and because the sealing elements are in direct contact with the moving trolley breast board of the circular cooler, the resistance is increased, the energy consumption is increased, the abrasion of the sealing elements is serious, and the sealing elements need to be frequently replaced. The method can reduce the entering of bulk materials and dust into the liquid tank, but cannot solve the influence of high-temperature waste gas on the liquid tank, and needs to be further optimized in order to improve the utilization rate of the circular cooler equipment and reduce the cost.
