Description
Technical Field
The utility model belongs to the technical field of sintered ring cooling machines, and particularly relates to a novel double-layer sealing device of a ring cooling machine.
Background
And the circular cooler cools the sinter by adopting a blowing mode. After the sintered ore at the temperature of about 700-800 ℃ is cooled by the circular cooler, the normal ore discharging temperature is below 100 ℃. The ring cooling machine generally adopts the traditional dynamic and static sealing made of rubber, and the principle of the ring cooling machine is that the sealing is realized by the friction between a rubber plate and a fixed steel plate.
The sealing effect of the trolley sealing plate of the circular cooler is always the bottleneck for the productivity of the sintering machine. Particularly, after the equipment runs for a period of time, along with the continuous abrasion and aging of the equipment, the air leakage rate of the annular cooling machine is further increased, the cooling effect of the sintering ore is poor due to the air leakage, the full-load production of the sintering machine cannot be caused, and the productivity of the sintering machine cannot be fully exerted. Meanwhile, the steam yield of the waste heat furnace is insufficient. The main reasons are that the original sealing device has short service life and poor sealing effect, so that cooling air cannot enter from the bottom of the trolley completely, sinter is cooled rapidly, and the feeding amount of the sintering machine during the trolley running is limited.
In the actual production operation, high temperature, wearing and tearing etc. lead to rubber sound sealed damage serious, and the closing plate life-span reduces, and ring cooling machine air leakage rate increases, not only influences waste heat steam's recovery volume, and waste heat recovery efficiency is low, and cooling efficiency reduces, and the amount of wind is extravagant, and sintering deposit ore discharge temperature is unstable and high just, and the belt can be scalded to high temperature ore entering finished product system, influences production even when serious. At the same time, the cooling power consumption is increased, and the maintenance cost of the sealing system is increased. Meanwhile, the working conditions of the large rotary frame, the wheel bearing and the like of the circular cooler are deteriorated, so that the failure rate of the equipment is increased. The sealing rubber plates need to be replaced in a large amount during maintenance, the labor intensity of workers is high, and the cost of spare parts is increased. Meanwhile, part of sinter particles and dust in the production are blown out of the circular cooler, and the environment of the area is seriously polluted.
After the circular cooler operates for a period of time, the problems of equipment aging, serious corrosion, high air leakage rate, high equipment operation energy consumption, bulk material leakage, large equipment maintenance workload, short equipment service life and the like exist, so that the sintering production is restricted, the environment of a plant area is influenced, and the requirements of energy conservation, emission reduction and noise reduction are not met.
