Patent ID: 7264039

Claim:
An apparatus for removing material accumulated on the exterior surfaces of adjacent heat exchanger plates arranged side-by-side in a spaced relationship in a bulk material heat exchanger, the apparatus comprising: a plurality of sleeves each open at both ends, one each being positioned through a respective heat exchanger plate such that each of said plurality of sleeves are arranged side-by-side with the open ends of adjacent sleeves in cooperating alignment with one another; a heat exchanger support member inserted through each of said plurality of sleeves; a plurality of cam followers, one each being attached to a respective sleeve of said plurality of sleeves; a plurality of cams spaced along said heat exchanger support member with one each in rolling contact with a respective cam follower, whereby rotation of said heat exchanger support member causes each heat exchanger plate to be raised and lowered individually based upon a profile of the respective cam resulting in removal of any material that has accumulated on the exterior surfaces of the heat exchanger plates.
