Abstract
The invention relates to a reciprocating grate cooler in which the drive arrangement is enclosed by a drive housing, the interior of which is closed off so as to be airtight against the atmosphere, but by contrast has a pressure equalization connection to the interior of the cooler housing. Such a reciprocating grate cooler is distinguished by a substantially reduced expenditure for the sealing of the cooler housing and a high degree of freedom from disruption.
Claims7
A reciprocating grate cooler construction having a cooler housing under positive air pressure;
- a drive mechanism external of said housing and having a reciprocable drive shaft extending through an elongate opening in a side wall of said cooler housing;
- an air tight drive housing enclosing said drive mechanism and encircling said shaft, said drive housing being in communication with the interior of said cooler housing via said opening;
- and a pressure equalization connection coupling said drive housing to said cooler housing at said opening to enable substantially equal pressure to be maintained within said cooler housing and said drive housing.
