Title: (EN) METHOD AND DEVICE FOR REGENERATING FOUNDRY SAND
(ZH) 用于再生铸造用砂的方法和设备
Abstract: front page image
(EN) The invention relates to a method for regenerating foundry sand, in particular for the renewed production of foundry moulds and/or foundry mould cores from the regenerated foundry sand, through removal of binding agent from a foundry sand/binding agent mixture, using a preferably absorbent, solid support means (6), wherein binding agent and support means (6) are separated from the foundry sand. According to the invention, the support means (6) is preferably brought into contact with the foundry sand/binding agent mixture, preferably added thereto, and together with the binding agent adhering thereto and/or incorporated therein is separated from the foundry sand (10).
(ZH) 本发明涉及一种用于再生铸造用砂的方法,尤其是用于由再生的铸造用砂重新制造铸造模具和/或铸造型芯的方法,该方法通过在使用优选吸收性的、固态的支撑剂(6)的情况下从铸造用砂/粘合剂混合物中去除粘合剂来实现,其中将所述粘合剂和支撑剂(6)从铸造用砂分离。根据本发明规定,使所述支撑剂(6)与铸造用砂/粘合剂混合物形成接触,优选地将所述支撑剂(6)添入到铸造用砂/粘合剂混合物中,并将所述支撑剂(6)与粘附在其上和/或结合到其中的粘合剂共同从铸造用砂(10)中分离。
