Spring adjusting type sealing device for annular cooler trolley

Abstract

The invention discloses a spring adjusting type sealing device for an annular cooler trolley, and belongs to the technical field of metallurgy. The spring adjusting type sealing device for the annular cooler trolley comprises an external guide rail, an internal guide rail and the annular cooling trolley, wherein the annular cooling trolley is erected between the external guide rail and the internal guide rail, and sealing assemblies are arranged between the annular cooling trolley and the external guide rail and between the annular cooling trolley and the internal guide rail separately; each sealing assembly comprises a vertical sealing plate and a sealing ring which are fixedly connected with the annular cooling trolley; an upper sealing bottom plate and a lower sealing bottom plate are arranged at one side, far away from the annular cooling trolley, of each vertical sealing plate; sealing adjusting plates are connected to the opposite inner sides of each sealing bottom plate through return springs separately; each sealing ring is slidably arranged between the two corresponding sealing adjusting plates; and each sealing ring is connected with the internal guide rail and the external guide rail separately. The annular cooling trolley is jointly supported and guided through the external guide rail and the internal guide rail, the sealing bottom plates and the sealing adjusting plates are supported through the return springs, and the sealing adjusting plates and the sealing rings are in a tightly attached state all the time, so that a good sealing effect is ensured; and the spring adjusting type sealing device for the annular cooler trolley is high in practicability, and capable of ensuring the cooling quality for sintered hot ore, and the recovery effect for waste heat.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, in particular to a spring-adjustable sealing device for a trolley of an annular cooler. Background technique [0002] The annular cooler is the abbreviation of the annular cooler. Its function is to cool the sintered hot ore unloaded from the sintering machine in time to prevent over-burning, and to recover and reuse the heat of the sintered hot ore, which can effectively avoid heat waste. The principle of the ring cooler is that the bottom of the ring cooler blows cooling air upwards, and the cooling air is heated by the sintered hot ore on the ring cooling trolley to become hot air, and is drawn out through the channel on the upper side of the ring cooler for heat recovery and reuse, thereby sintering the hot ore It can cool down in time to prevent overheating. [0003] In order to reduce the airflow at the bottom of the trolley from escaping from the surroundings and reduce the air leakage...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that during the use of today’s trolley sealing device, the rollers of the trolley and the inner and outer guide rails will wear and tear, resulting in uneven indentations, which will affect the sealing performance of the sealing device, resulting in large air leakage and seriously affecting the safety of sintered hot ore. To solve the problems of cooling quality and waste heat recovery, the present invention provides a spring-adjustable annular cooler trolley sealing device
