Description

TECHNICAL FIELD

[0002] The grate cooler is an important main equipment in the clinker calcination system of a cement plant, mainly functions to cool and convey cement clinker, and provides hot air for a rotary kiln and a decomposing furnace, is the main equipment for heat recovery of the calcination system, and is used for rapidly cooling hot clinker by the cold air passing through the grate plate holes and gaps during the process of pushing the hot clinker to the discharge end by the reciprocating grate plate when the grate cooler is working. The sudden cooling mode can improve the quality and grindability of the clinker, and recovers part of the heat of the clinker, thereby improving the energy utilization efficiency. The grate cooler needs to use a fan to cool the clinker during work. Due to the influence of small sundries such as flying insects, waste spinning fly fibers and willow catkins, the grate gap of the grate cooler is prone to be blocked, so that the frequency of the fan is increased, the power consumption is increased, and the cooling effect of the clinker is poor. The grate cooler isolator can prevent the grate gap of the grate cooler from being blocked. The grate cooler isolator is installed at the inlet of the fan muffler of the grate cooler, and can effectively isolate small sundries such as flying insects, waste spinning fly fibers and willow catkins.

[0003] During production of the grate cooler isolator, the plug pins below the net rack are welded on the net rack. After leaving the factory, the same type of net rack can be fixedly installed only at the air inlet of the corresponding fan due to the unadjustable position of the plug pins. The same type of net rack cannot be fixedly installed at the air inlet of the fan with a larger or smaller size due to the unadjustable position of the plug pins, and has relatively large limitations. Therefore, the grate cooler isolator needs to be improved. CONTENT OF THE UTILITY MODEL
