Abstract
"APARELHO ROTOR DE DESOBSTRUçãO BIDIRECIONAL E MéTODO PARA A UTILIZAçãO DO MESMO". A presente invenção refere-se a um aparelho rotor que pode ser retirado (10) tendo uma parte de corpo substancialmente cilíndrica (32), a parte de corpo (32) tendo um orifício de fluxo central (34) através daí e preso a um tubo em forma de espiral (22), incluindo um orifício de fluxo de fluido central (34) em comunicação fluida com o orifício interno da tubulação em forma de espiral (35); uma pluralidade de orifícios de fluxo (40) espaçados igualmente dentro do corpo, com os orifícios de fluxo (40) permitindo que o fluxo de fluido seja injetado a uma certa pressão predeterminada através dos orifícios de fluxo (40), de modo a ser emitido na extremidade dianteira do rotor para definir uma vaporização de pressão elevada de fluido, ou material similar para quebrar bloqueios de dejetos (70) no oleoduto, tais como parafina e similar; os dejetos (70) retirados através do orifício central (34)de volta para a tubulação em forma de espiral (35) para serem armazenados em um tanque (157) ou similar na superfície. Ainda está incluída uma pluralidade de elementos em forma de taça flexíveis (24), espaçados ao longo da parede externa do corpo do rotor (25), cada elemento em forma de taça (24) preso a um anel metálico interno (26) em torno do corpo (25) do rotor, com elementos flexíveis (24) fazendo contato com a parede (13) do oleoduto, de modo a prover uma vedação de fluido contínua entre a parede (13) do oleoduto e as extremidades da pluralidade de elementos em forma de taça flexíveis (24). Intermediário a cada elemento de taça (24) é provido um anel de segurança compressível (28) que irá comprimir sob pressão excessiva do oleoduto, permitindo, assim, que o fluido passe através da pluralidade de elementos em forma de taça flexíveis (24), reduzindo a pressão no oleoduto. é ainda provida uma pluralidade de seis orifícios de fluxo (40) em torno do orifício de fluxo interno (34) para ajustar a força que permite que o fluxo passe através de uma pluralidade de orifícios (40) em cada direção provendo-se primeira e segunda molas e empuxo (42, 44) de uma força compressível predeterminada para permitir que as molas (42, 44) sejam comprimidas e efetuem um fluxo de fluido na direção na qual o fluxo percorre os orifícios (40).
