Description

Technical Field

[0001] The present invention relates to the technical field of pushing devices, and particularly to a hydraulic pusher device for a grate cooler with good stability. Background Art

[0002] The hydraulic pusher device for a grate cooler is a pushing device specifically used for high-temperature clinker inside the grate cooler in the cement industry. When large pieces of clinker start to accumulate on the fixed beam inside the grate cooler, if not cleaned in time, it will accumulate like a snowman and eventually may block the kiln mouth, resulting in the shutdown of the kiln and interruption of the production line, which will cause serious economic losses to the enterprise.

[0003] Chinese Patent CN207472059U discloses a hydraulic pusher device for a grate cooler, which includes a base corresponding to the grate cooler wall. A pusher box body is slidably connected left and right on the base. The right end of the pusher box body passes through the grate cooler wall. A sealing box body is hermetically and fixedly connected to the left surface of the grate cooler wall. The pusher box body passes through the middle of the sealing box body. A sealing block and graphite packing are hermetically and fixedly connected inside the sealing box body. The pusher box body hermetically slides through the middle of the sealing block and graphite packing; the sealing box body is also hermetically and fixedly connected with a blowpipe. The blowpipe passes through the sealing box body, and a row of small holes are opened on the blowpipe inside the sealing box body. However, this device cannot clamp and fix the material, resulting in easy detachment of the material during the transfer process.
