Cooling and dust exhaustion plant for foundry sand

Abstract

Cooling and dust exhaustion plant for foundry sand, comprising: a substantially closed structure defining a cooling channel extending according to a longitudinal axis and with an inlet section for the sand to be treated and an outlet section for the treated sand, a heat exchanger positioned inside the aforesaid structure and extending along the longitudinal axis of the cooling channel, a cooling circuit to allow a flow of cooling fluid to circulate in the heat exchanger, a fan positioned to send an air flow to an air chamber positioned under said heat exchanger, a dust suction chamber positioned above said heat exchanger, and a suction duct communicating with said suction chamber and associated with a filter unit, in which the heat exchanger comprises a plurality of tubes which extend in a transverse direction in relation to said longitudinal axis.
