Abstract

"SISTEMA DE REGENERAçãO DE AREIAS ALCALINAS E AREIA VERDE SINTéTICA DE FUNDIçãO". A presente Patente de Invenção diz respeito à Sistema de Regeneração de Areias Alcalinas e Areia Verde Sintética de Fundição, (1), caracterizado por ser constituído desmoldador vibratório (2), o qual separa as peças fundidas do bloco de areia formado por resina alcalina ou areia verde; destorroador vibratório (3), o qual recebe os torrões de areia aglomerados com resina alcalina ou areia verde, sendo que nesta etapa, através de atrição, os grãos são desagregados, peneirados para manter a distribuição granulométrica similar ao de uma areia nova, a qual deu origem aos torrões; sistema de insuflamento de ar (4) no destorroador vibratório (3), para colocar os finos em suspensão; transporte pneumático (5) da areia destorroada e o silo de estocagem desta mesma areia; separador magnético (6) para eliminação das partículas metálicas que estão misturadas à areia; lavador (7) de areia, o qual através de agitação mais água, solubilizam os componentes inorgânicos das resinas alcalinas e areia verde; sistema de separação da água da areia com a utilização de hidrociclone e peneira desaguadora (8); secador (9) da areia por leito fluidizado; resfriador (10) de areia por leito fluidizado; conjunto de tanques e bombas (11) para recirculação da água de lavagem e correção para reutilização; espessador (12) para separação da cama gerada na recuperação da água."ALKALINE SAND AND SYNTHETIC FOUNDRY GREEN SAND REGENERATION SYSTEM". The present invention relates to the Regeneration System of Alkaline Sands and Synthetic Green Sand Foundry, (1), characterized in that it consists of vibratory demoulder (2), which separates the castings from the sand block formed by alkaline resin or green sand; vibratory destroying machine (3), which receives the clumps of sand agglomerated with alkaline resin or green sand, and in this stage, through attrition, the grains are disaggregated, sieved to maintain the particle size distribution similar to that of a new sand, which gave rise to clods; air supply system (4) in the vibratory breaker (3) for suspending the fines; pneumatic conveying (5) of the broken sand and the storage silo of the same sand; magnetic separator (6) for the disposal of metal particles which are mixed with sand; sand washer (7) which, by stirring more water, solubilizes the inorganic components of alkaline resins and green sand; sand water separation system using hydrocyclone and dewatering screen (8); fluid bed sand dryer (9); fluid bed sand chiller (10); set of tanks and pumps (11) for recirculation of wash water and correction for reuse; thickener (12) for separating the bed generated in water recovery.
