Abstract
The present invention concerns a casting sand cooler comprising a sand chamber having an air inlet optionally with a fan for the feed of air into the sand chamber and an air outlet optionally with a fan for sucking air out of the sand chamber. To provide an improved casting sand cooler in which the sand discharge during the cooling operation by way of the air outlet is markedly reduced, it is proposed according to the invention that a dynamic wind sifter which is rotatable about an axis and which is so arranged that substantially the complete air flow leaving the sand chamber through the air outlet is passed through the dynamic wind sifter.
Claims21
A casting sand cooler comprising a sand chamber having an air inlet (3) and an air outlet (5), wherein the air inlet (3) has a fan for the feed of air into the sand chamber and/or the air outlet (5) has a fan for sucking air out of the sand chamber (2), characterised in that a dynamic wind sifter (10) which is rotatable about an axis and which is so arranged within the casting sand cooler and is operable such that substantially the complete air flow leaving the sand chamber (2) through the air outlet (5) is passed through the dynamic wind sifter (10) and solid particles are removed from the discharge air flow and remain in the sand chamber or can be at recycled thereinto.
