Sealing structure of grate cooler

Abstract

The invention discloses a sealing structure of a grate cooler, and belongs to the technical field of cement mechanical equipment. The sealing structure comprises a plurality of sealing modules connected through relative sliding mechanisms, each sealing module comprises a segmental beam, a grate plate, a striker plate, a relative sliding mechanism, an abrasion-proof and leakage-proof system and a vent valve, wherein the grate plates are mounted above the segmental beams, the striker plates are mounted at the edges of the grate plates, the vent valves are installed at the bottoms of the segmental beams, the abrasion-proof and leakage-proof systems are installed on the relative sliding mechanisms, each relative sliding mechanism comprises a concave sealing plate, a convex sealing plate, an abrasion-proof block and an L-shaped plate, the concave sealing plates, the convex sealing plates and the L-shaped plates are sequentially arranged together in a sleeved mode from top to bottom, the concave sealing plates, the L-shaped plates and the convex sealing plates slide relatively, the abrasion-proof blocks are installed on one sides of the concave sealing plates, and each abrasion-proof andleakage-proof system comprises an abrasion-proof plate and an abrasion-proof gap adjusting plate. The sealing structure can solve the problem of equipment loss caused by reverse friction between clinker and equipment can be effectively avoided, the sealing performance of the device is improved, and the width and the length can be adjusted as required.

Description

technical field [0001] The invention belongs to the technical field of cement machinery and equipment, in particular to a sealing structure of a grate cooler. Background technique [0002] The grate cooler is an important host equipment in the clinker firing system of the cement plant. Its main function is to cool and transport the cement clinker. When in use, the hot clinker is unloaded from the kiln mouth to the grate plate. Under the push of the reciprocating grate plate, it is distributed along the whole length of the grate bed to form a material bed with a certain thickness, and the cooling air is blown into the material layer from the bottom of the material bed. Inside, the hot clinker is cooled. Since the hot clinker is placed on the grate cooler, its sealing structure is very important for the grate cooler, but the traditional sealing structure of the grate cooler has only one concave sealing plate and one L-shaped plate. , When the grate plate conveys clinker, the...

Problems solved by technology

But the disadvantage of this device is that it is very easy to wear and tear. When the cement clinker is pushed, the clinker and the device will have friction opposite to the direction of movement, and the friction area is large, resulting in serious wear and tear of the device.
