Description

Technical Field

[0001] The utility model relates to the technical field of grate beds of grate coolers, in particular to a driving shaft sealing structure of a grate bed of a grate cooler. Background Art

[0002] Currently, the grate bed drive shaft seal in push-type grate coolers is poorly sealed, potentially causing dust leakage and air leakage, impacting the equipment's environmental hygiene. The original seal was a cast aluminum movable seal, which was not only expensive but also prone to fall apart due to scratches and stress during use. Furthermore, replacing the seal plate was cumbersome, requiring the complete removal of the outer pulley. Existing grate cooler grate bed drive shaft seals were costly and provided poor sealing effectiveness.

[0003] Application number 201921773287.6 discloses a grate cooler grate bed drive shaft sealing structure, comprising a fixed sealing plate, a movable sealing plate, and a support plate. The fixed sealing plate is fixedly mounted on the grate cooler housing by bolts. The movable sealing plate is mounted on the grate bed drive shaft and is located between the grate cooler housing and the support plate. A gap is left between the movable sealing plate and the grate cooler housing. The support plate is fixedly mounted on the grate bed drive shaft. A spring is installed on the support plate near the movable sealing plate. A support wheel is installed on the movable sealing plate near the fixed sealing plate. The spring presses the movable sealing plate against the fixed sealing plate. A sealing assembly forming a labyrinth seal structure is provided between the fixed sealing plate and the movable sealing plate. This utility model extends the service life of the labyrinth seal, ensures the sealing effect, reduces the cost of spare parts, and also reduces maintenance costs.

[0004] However, there are some shortcomings. The grate cooler grate bed push shaft sealing structure extends the service life of the labyrinth seal through the sealing component of the labyrinth sealing structure, ensures the sealing effect, reduces the spare parts cost, and also reduces the maintenance cost. However, the labyrinth sealing structure set in the device is easily affected by the push shaft when used for a long time, which leads to a reduction in the life of the device. Utility Model Content
