SAND HEATING APPARATUS FOR SAND BINDER MOLDING

摘要

PURPOSE: A sand heating apparatus for furan molding is provided to maintain the temperature of sand necessary for sand molding by installing sand heating units consisting of heating coils or an infrared lamp at every section the sand is transferred. CONSTITUTION: A sand heating apparatus for furan molding comprises a sand storage tank (110), a sand transferring unit (120), sand heating units (130), and a sand stirring unit (140). The sand storage tank stores the sand delivered from the external sand export pipeline. The sand transferring unit comprises: a first horizontal conveyor (122) which receives the sand from the sand storage tank and transfers the sand to the rear end; a vertical conveyor (124) which transfers the sand delivered from the first horizontal conveyor to the rear end; and a second horizontal conveyor (126) which transfers the sand delivered from the vertical conveyor to the rear end. The sand heating unit comprises a first heater (132) heating the sand transferred by the first horizontal conveyor and a second heater (134) the sand transferred by the second horizontal conveyor. The sand transferring unit ejects the sand delivered from the second horizontal conveyor, furan, and a hardening agent to the outside after stirring.
