Description
Separador Magnético de Estrutura Cruzada com Circuito MagnéticoRotórico Tetrapolar e Rotores AnularesMagnetic Circuit Breaker with Magnetic CircuitTetrapolar Rotor and Annular Rotors
Refere-se a presente invenção a um separador magnético que permite duplicara capacidade de produção obtida quando comparado aos atuais modelosdisponíveis no mercado. Uma nova forma construtiva cuja característicamarcante é uma forma estrutural cruzada que permite a duplicação do númerode pólos magnéticos e a duplicação do número de pontos de alimentação e delavagem. Outra característica vantajosa é a modificação dos dois rotores cujoformato circular maciço é modificado para a forma anular, o que reduzsubstancialmente o peso do equipamento. Essa forma rotórica anular, maisleve e econômica, é possibilitada pela localização dos pólos magnéticos lado alado com polaridades alternadas norte/sul em torno da periferia do rotor, oque faz com que as linhas de força magnéticas tenham um percurso tangencialao rotor. A polaridade norte/sul/norte/sul do rotor superior se torna no rotorinferior sul/norte/sul/norte, isto é, haverá um deslocamento de 180° elétricosentre os pólos situados no rotor superior, em relação aos pólos do rotorinferior, permitindo, assim, o completo fechamento das linhas de forçamagnéticas entre os dois rotores. Esta idéia torna possível obter umequipamento de alta produção com substancial economia de materiais e commelhor aproveitamento da área de instalação. Do ponto de vista demanutenção do equipamento, a nova forma construtiva permite ainda a trocadas bobinas de forma simplificada, sem a necessidade de desmontar grandeparte do equipamento, como ocorre nos modelos atualmente em uso.The present invention relates to a magnetic separator which allows double the production capacity obtained when compared to current models available on the market. A new constructive form whose characteristic feature is a cross-structural form that allows the doubling of the number of magnetic poles and the doubling of the number of feed and wash points. Another advantageous feature is the modification of the two rotors whose massive circular shape is modified to the annular shape, which substantially reduces the weight of the equipment. This more lightweight and economical annular rotor shape is made possible by the location of the winged magnetic poles with alternating north / south polarities around the periphery of the rotor, which makes the magnetic force lines have a tangential path to the rotor. The north / south / north / south polarity of the upper rotor becomes the lower rotor south / north / south / north, ie there will be a 180 ° electric displacement between the poles located in the upper rotor, relative to the lower rotor poles, allowing, thus the complete closure of the magnetic force lines between the two rotors. This idea makes it possible to achieve a high production equipment with substantial material savings and better use of the installation area. From the point of view of equipment maintenance, the new construction also allows the changeover of coils in a simplified manner, without the need to disassemble the large part of the equipment, as occurs in the models currently in use.
Exemplos dos separadores magnéticos existentes no mercado e em relaçãoaos quais esta invenção traz vantagens em relação à produtividade, economiade materiais e de manutenção substanciais, são aqueles separadoresmagnéticos objeto das patentes USA 3830367 e CAN 717 830. A demandaatual da industria no ramo de mineração, mormente no setor deprocessamento mineral de materiais cada vez mais pobres, é pela busca deequipamentos mais compactos e com maior capacidade de produção e demanutenção mais fácil. Atualmente, neste tipo de equipamento atualmenteem uso, a construção é sempre executada com o uso de pólos magnéticosmontados em posições diametralmente opostas em relação ao rotor e em cadarotor são utilizados dois pontos de alimentação, dois pontos de lavagem demédio e dois pontos de lavagem de concentrado, além de serem utilizadosrotores com discos maciços. A presente invenção pode ser melhor entendidacomparando-se a figura 1, na qual é representado o modelo atual desse tipo deequipamento, com a figura 2, na qual pode ser observada a nova formaconstrutiva. Na figura 1 observa-se a existência de quatro bobinas (1) e nafigura 2 pode-se observar a existência de oito bobinas (1). Na figura 3,correspondente à configuração atual, as bobinas (1) estão opostas ao rotorcircular maciço (2). As linhas de força magnética (3) circulam do pólo nortepara o pólo sul por dentro do rotor circular maciço (2). Na figura 4 sãomostradas as quatro bobinas (1) localizadas com polaridades norte e sulalternadas em torno da periferia do rotor anular (4). As linhas de forçamagnética (3) que saem do pólo norte se dividem à metade e seguem emdireção aos dois pólos sul adjacentes utilizando como caminho para esse fimapenas a periferia do rotor anular (4). É esta característica de fluxo magnéticocirculando apenas na região externa do rotor anular (4) e com uma quantidadede linhas de força correspondente à metade das linhas de força que saem dospólos que permite que o mesmo seja construído na forma anular, pois aslinhas de força não o cruzam diametralmente como ocorre nos modelos destetipo de equipamento existentes no mercado. Na figura 3, correspondente aosmodelos atuais, existem apenas dois pontos de alimentação (5) em cada rotorcircular maciço (2) e na figura 4, objeto dessa invenção, existem quatropontos de alimentação (5) situados em cada rotor anular (4). Na figura 4 ospontos de lavagem de médio (6) e de concentrado (7) são no total de quatro,respectivamente, enquanto que na figura 3 esses mesmos pontos totalizamduas unidades. Portanto o equipamento representado na figura 4 tem o dobrode capacidade de processamento em relação ao modelo atual de mesmo porte,mostrado na figura 3. Na figura 5 é demonstrado como a unidade polar quesuporta as bobinas (8) pode ser retirada do equipamento com a finalidade deefetuar a troca das bobinas (1) sem necessidade de retirar os rotores e,portanto, desmontar a maior parte da máquina como ocorre nos equipamentosatuais.Examples of magnetic separators on the market and in which this invention has advantages over substantial productivity, material economy and maintenance are those magnetic separators which are the subject of USA 3830367 and CAN 717 830. The current demand of the mining industry, particularly In the sector of mineral processing of increasingly poor materials, it is by seeking more compact equipment with greater production capacity and easier maintenance. Currently, in this type of equipment currently in use, the construction is always performed using magnetic poles mounted diametrically opposite to the rotor and in the rotor. Two feed points, two demic wash points and two concentrate wash points are used. , besides being used rotors with massive disks. The present invention can be better understood by comparing Figure 1, in which the current model of this type of equipment is depicted, with Figure 2, in which the new constructive form can be observed. Figure 1 shows the existence of four coils (1) and in figure 2 one can observe the existence of eight coils (1). In Figure 3, corresponding to the current configuration, the coils (1) are opposite the massive rotorcircular (2). The magnetic force lines (3) circulate from the north pole to the south pole inside the massive circular rotor (2). Figure 4 shows the four coils (1) located with north and south polarities around the periphery of the annular rotor (4). The lines of magnetic force (3) that leave the north pole divide in half and follow the two adjacent south poles, using as a path to this axis the periphery of the annular rotor (4). It is this characteristic of magnetic flux circulating only in the outer region of the annular rotor (4) and with a quantity of power lines corresponding to half of the power lines leaving the poles that allows it to be built in the annular form, since the power lines do not. cross diametrically as it occurs in the models of this type of equipment on the market. In Figure 3, corresponding to the current models, there are only two feed points (5) in each massive rotorcircular (2) and in Figure 4, object of this invention, there are four feed points (5) located in each annular rotor (4). In figure 4 the washing points of medium (6) and concentrate (7) are a total of four, respectively, while in figure 3 these same points total two units. Therefore, the equipment shown in figure 4 has a double processability compared to the current model of the same size, shown in figure 3. Figure 5 shows how the polar unit that supports the coils (8) can be removed from the equipment for the purpose. Replace the coils (1) without removing the rotors and therefore dismantle most of the machine as in the current equipment.
