Description
ULTRACENTRÍFUGA DE LEVITAÇÃO MAGNÉTICA MAGNETIC LEADING ULTRACENTRIFUG
ESTABILIZADA POR EMPUXO PUSH STABILIZED
Campo de Invenção Field of Invention
A presente invenção tem aplicação nas áreas de centrífugas e ultracentrífugas para uso industrial ou doméstico. The present invention has application in the areas of centrifuges and ultracentrifuges for industrial or domestic use.
A presente invenção refere-se a uma ultracentrífuga constituída por um motor homopolar usado para centrifugar e separar os constituintes de soluções líquidas, coloidais ou radioisótopos. The present invention relates to an ultracentrifuge consisting of a homopolar motor used to centrifuge and separate constituents from liquid, colloidal or radioisotope solutions.
Antecedentes Background
As centrífugas e ultracentrífugas usadas industrialmente giram em torno de um eixo mecânico que gera uma força centrífuga relativa com capacidade de sedimentar sólidos de líquidos ou líquidos imis íveis de diferentes densidades, separando-os. Industrially used centrifuges and ultracentrifuges revolve around a mechanical axis that generates a relative centrifugal force capable of settling solids from liquids or immobile liquids of different densities, separating them.
Após certo tempo de uso, estas exigem manutenção dos seus mancais devido ao desgaste causado pelo atrito entre o rotor e as peças fixas do motor. Além disso, têm velocidades limitadas, também pelo motivo anterior. Alguns modelos de motores ou ultracentrífugas de levitação magnética comerciais têm seus funcionamento baseado na repulsão de ímãs de pólos iguais para suspender o rotor das partes fixas (estator) na região dos seus mancais (Patente n° BR 0804447-3) ou pela combinação de mancais de ímãs permanentes com bobinas que geram! campos magnéticos produzidos por correntes elétricas com a finalidade de controlar e estabilizar a levitação do rotor (Patente n° US 3512852j; Patente n° US 4585282; Patente n° US 3888553). O grande problema dos motores de levitação magnética anteriores é que a estabilização do rotor utiliza exclusivamente bobinas de fios condutores controlados - por circuitos eletrônicos que consomem energia na estabilização do rotor, neutjralizando variações da inclinação do rotor durante o seu giro. Oscilações no eixo de giro do rotor (presseção do rotor como ocorre com o pião de brinquedo ao reduzir a sua velocidade de giro), devem-se a não homogeneidade intrínsecas dos materiais, causando desbalanceamento do rotor. Oscilação no rotor durante a sua rotação pode também ocorrer quando o motor é deslocado de um lugar para o outro ou quando há mudanças de nivelamento da superfície ou quando a superfície é abalada ou sofre vibração. Caso haja um destes fatores acima o rotor em alta velocidade e
em levitação pode tocar o estator acidentalmente resultando em destruição do motor. O problema da estabilização de giro de levitação por campos eletromagnéticos é que o circuito que o comanda, além de complexo, consome muita energia para estabilizar o rotor. Além disso, caso haja uma pane no circuito eletrônico que comanda a estabilização, o rotor levitante em alta velocidade poderá bater no estator causando destruição no motor caso haja vibração ou deslocamento do motor como um todo. After some time of use, they require maintenance of their bearings due to wear caused by friction between the rotor and the fixed motor parts. Moreover, they have limited speeds, also for the previous reason. Some models of commercial magnetic levitation motors or ultracentrifuges have their operation based on repulsion of equal pole magnets to suspend the rotor of fixed parts (stator) in the region of their bearings (Patent No. BR 0804447-3) or by the combination of bearings. of permanent magnets with coils that generate! magnetic fields produced by electric currents for the purpose of controlling and stabilizing rotor levitation (US Patent No. 3,512,852; US Patent No. 4,585,282; US Patent No. 3,888,553). The major problem with previous magnetic levitation motors is that rotor stabilization exclusively uses controlled lead wire coils - which use energy-consuming electronic circuits in rotor stabilization, neutralizing variations in rotor inclination during rotation. Oscillations in the rotor spinning axis (rotor pressure as with the toy spinning top by reducing its spinning speed) are due to the intrinsic non-homogeneity of the materials, causing rotor unbalance. Rotor oscillation during rotation can also occur when the engine is moved from one place to another or when surface leveling changes or when the surface is shaken or vibrated. If there is one of these factors above the high speed rotor and in levitation may accidentally touch the stator resulting in motor destruction. The problem with levitation spin stabilization by electromagnetic fields is that the circuit that drives it, besides being complex, consumes a lot of energy to stabilize the rotor. In addition, if there is a breakdown in the electronic circuit that drives stabilization, the high-speed levitator rotor can hit the stator causing motor destruction if the motor is vibrated or displaced as a whole.
Além disso, outro inconveniente é o tempo de resposta a perturbações de giro do rotor. Em grandes velocidades o circuito eletrônico não poderá responder a rápidas oscilações do eixo, podendo resultar em acidentes. In addition, another drawback is the response time to rotor rotational disturbances. At high speeds the electronic circuit will not be able to respond to rapid shaft oscillations and could result in accidents.
O problema acima pode ser evitado pela combinação j de ímãs permanentes e materiais que naturalmente repelem ímãs e ab mesmo tempo é líquido e moldável, como o mercúrio e o gálio, que também atuam como condutor de eletricidade, garantindo estabilidade ao rotor levitante pela adição do empuxo entre a base do rotor metal líquido (mercúrio ou gálio). O empuxo é uma força que dá sustentação ao avião e estabiliza os navios sobre o mar. Neste caso, o rotor levitará pelas forças de repulsão magnética (pólos de mesmo tipo) e terá sua estabilidade garantida pela força de empuxo em sua base. Esta última contrabalanceará instantaneamente qualquer desequilíbrio sofrido pelo rotor durarte o seu giro pelo princípio de ação e reação, amortecendo-o NE a necessidade de gasto de energia como acontece com a estabilização eletrônica. The above problem can be avoided by combining permanent magnets and materials that naturally repel magnets and at the same time is liquid and moldable, such as mercury and gallium, which also act as an electricity conductor, ensuring stability to the levitating rotor by the addition of thrust between the base of the liquid metal rotor (mercury or gallium). Thrust is a force that supports the plane and stabilizes the ships over the sea. In this case, the rotor will levitate by magnetic repulsion forces (poles of the same type) and have its stability guaranteed by the buoyant force at its base. The latter will instantly counterbalance any imbalance suffered by the rotor during its rotation by the principle of action and reaction, damping it NE the need for energy expenditure as with electronic stabilization.
Em termos simples, a presente invenção utiliza o mesmo princípio das centrífugas, com a diferença de que não gira em torno de um eixo mecânico, mas sim de um eixo magnético estabilizado pelo empuxo resultando em maior economia tanto em manutenção quanto em energia e reduzindo possíveis acidentes causados por instabilidades no girq do rotor levitante. Simply put, the present invention uses the same principle as centrifuges, except that it does not revolve around a mechanical axis, but rather a thrust-stabilized magnetic axis resulting in greater savings in both maintenance and energy and reducing possible accidents caused by jitter rotor rotor instability.

Esta invenção apresenta os metais líquidos à temperatura' ambiente (por exemplo: mercúrio ou gálio) como j solução das eventuais instabilidades presentes pelo rotor levitante durante o giro graças1 ao efeito de empuxo na região de interface entre a base. do rotor e o metal líquido. Ocorre uma levitação e uma estabilidade baseadas na repulsão entre imãs de NdFeB ou AINiCo e materiais líquidos altamente diamagnéticos como o mercúrio ou o gálio.

Energy consumption and friction are mitigated by the presence of mercury and gallium as the electrical conductor between the moving part (rotor) and the fixed part of the engine, which also acts as a damper or stabilizer for any oscillations in the inclination of the rotating shaft. rotor by the effect of the action and reaction caused by the thrust between the rotor base and liquid phase mercury or gallium preventing possible accidents.
Descrição Detalhada Detailed Description
A disponibilidade de imãs de grande força (NdFeB - Liga de Neodímio, Ferro e Boro; AINiCo - Liga de Alumínio, Níquel, Cobajto) torna possível a construção deste pequeno e económico aparelho de [flutuação de ar, com o grafite e o bismuto como imãs diamagnéticos. Materiais diamagnéticos repelem ambos os pólos magnéticos. A força da gravidade que age sobre ele é quase completamente anulada pela força ô\ atração de um imã que se encontra na parte inferior do motor. Duas lacas de grafite ou bismuto, uma acima e outra abaixo do imã NdFeB o AINiCo, força este último a manter uma posição de equilíbrio estável, já q e ambos os pólos do imã são repelidos pelas placas de grafite ou bismuto (diamagnetismo). The availability of high strength magnets (NdFeB - Neodymium, Iron and Boron Alloy; AINiCo - Aluminum Alloy, Nickel, Cobajto) makes it possible to build this small and economical [air flotation device], with graphite and bismuth as diamagnetic magnets. Diamagnetic materials repel both magnetic poles. The force of gravity acting on it is almost completely nullified by the force of attraction of a magnet at the bottom of the engine. Two graphite or bismuth lacquers, one above and one below the NdFeB or AINiCo magnet, forces the latter to maintain a stable equilibrium position, as both poles of the magnet are repelled by the graphite or bismuth plates (diamagnetism).
