Title (EN) AN APPARATUS AND METHOD FOR THAWING MATERIALS STORED IN GONDOLA-TYPE CONTAINERS
(FR) APPAREIL ET PROCEDE POUR DEGELER DES MATERIAUX STOCKES DANS DES CONTENEURS DU TYPE GONDOLE
Abstract: front page image
(EN)An apparatus and method for thawing particular material, such as coal (18), stored in gondola-type containers (12), wherein the container is positioned in a shielded and grounded enclosure (90), and is engaged by shielded hood (10) having an open face matching the dimensions of the open face of the container to form a microwave cavity between the hood and the container. Plural magnetrons (20) are located in the hood, and are energized upon formation of the microwave cavity, to emit microwave radiation into the material in the container, whereby the material is heated and thawing thereof takes place. Prior to formation of the microwave cavity, the top surface of the container open face (54) is thoroughly cleaned, and during energization of the magnetrons, gases released by the particular matter being heated are evacuated (40) from the microwave cavity. After energization of the magnetrons for a selected period of time, the shielding hood is removed from the gondola-type container, and the container is then processed to an adjacent discharge cite exterior to the RF shielded enclosure. The apparatus and process is virtually entirely automated under the control of a centrally located microprocessor (61).
(FR)Appareil et procede de degel d"un materiau particulier, tel que du charbon (18), stocke dans des conteneurs du type gondole (12), ou le conteneur est positionne dans une enceinte protegee et mise a la terre (90), et est soumis a l"action d"une hotte de protection (10) ayant une face ouverte correspondant aux dimensions de la face ouverte du conteneur pour former une cavite a micro-ondes entre la hotte et le conteneur. Une pluralite de magnetrons (20) sont situes dans la hotte, et sont alimentes a la formation de la cavite a micro-ondes pour emettre une radiation de micro-ondes dans le materiau se trouvant dans le conteneur, chauffant le materiau et le degelant. Avant formation de la cavite a micro-ondes, la surface superieure de la face ouverte du conteneur (54) est soigneusement nettoyee, et pendant l"excitation des magnetrons, et les gaz qui se degagent du materiau particulier chauffe sont evacues (40) de la cavite a micro-ondes. Apres excitation des magnetrons pendant une periode de temps determinee, la hotte de protection est retiree du container du type en gondole, et le container est alors amene vers un lieu de decharge adjacent exterieur a l"enceinte protegee (RF). L"appareil et le procede sont pratiquement entierement automatises par la commande d"un microprocesseur central (61).
