Изобретение относитс к электротехнической промышленности и может быть использовано при утилизации отработанных аккумул торов .The invention relates to the electrical industry and can be used in the disposal of used batteries.
Известен способ разделени отработанных аккумул торов на составные компоненты путем дроблени с одновременным нагревом газами , отделени активной массы от остальных материалов просеиванием через сита и флотационного разделени металлических и неметаллических компонентов.There is a known method of separating waste batteries into composite components by crushing with simultaneous heating with gases, separating the active mass from other materials by sieving through sieves and flotation separation of metal and non-metal components.
Этот способ малопроизводителен из-за использовани флотационного разделени компонентов , после чего требуетс многократна промывка и сушка.This method is inefficient due to the use of flotation separation of the components, after which repeated washing and drying are required.
Наиболее близким к предлагаемому по технической сущности и достигаемым результатам вл етс способ разделени отработанных аккумул торов на составные компоненты путем дроблени , сушки и пневмосепарации на металлические и неметаллические фракции.The closest to the proposed technical essence and the achieved results is the method of separation of waste batteries into components by crushing, drying and pneumo-separation into metal and non-metal fractions.
Этот способ длителен, так как сушка и пневмосепараци производ тс раздельно. Кроме того, конечные продукты имеют примеси, так как не все детали, поступающие на сепарацию, достаточно высушены и содержат шлам повышенной влажности.This method is long lasting, since drying and pneumatic separation are carried out separately. In addition, the final products have impurities, since not all parts entering the separation are sufficiently dried and contain sludge of high humidity.
С целью упрощени технологии и повышени чистоты конечных продуктов по предлагаемому способу сушку и пневмосепарацию осуществл ют нагретым до 150-200°С газообразным теплоносителем в течение 4-5 сек.In order to simplify the technology and increase the purity of the final products according to the proposed method, drying and pneumatic separation are carried out with gaseous coolant heated to 150-200 ° C for 4-5 seconds.
Предлагаемый способ заключаетс в следующем .The proposed method is as follows.
Отработанные аккумул торы со слитым электролитом подают на дробление до крупности 75 мм. Раздробленный аккумул торный лом подвергают классификации на фракции и -3 мм дл выделени основной части шлама. Раздробленный аккумул торный лом крупностью мм с содержанием шлама 6,5 и 20% раздел ют на составные компоненты. В случае свинцовых аккумул торов этими компонентами вл ютс свинец, органическа масса и остаток окисно-сульфатного шлама. Эти компоненты раздел ют между собой по разнице их удельного веса в струе газа, нагретого до 150-200°С и направленного навстречу движущимс частицам материала. Врем контактировани нагретого газа с раздел емыми материалами - 4-5 сек. Полученные конечные продукты разделени - свинец и органическа масса - содержат в своемSpent batteries with drained electrolyte are fed to crushing to a particle size of 75 mm. The crushed scrap battery is classified into fractions and -3 mm to isolate the bulk of the sludge. The crushed battery scrap with a particle size of mm with a sludge content of 6.5 and 20% is divided into composite components. In the case of lead batteries, these components are lead, organic matter and the residue of sulphate oxide. These components are divided among themselves according to the difference in their specific gravity in a stream of gas heated to 150-200 ° C and directed towards the moving material particles. The contact time of the heated gas with the materials to be separated is 4-5 seconds. The resulting separation products, lead and organic matter, contain in their
5 составе не более 1 и 1,7% щлама соответственно . Выделенные материалы подвергаютс металлургической переработке.5 of no more than 1 and 1.7% schlama, respectively. The recovered materials undergo metallurgical processing.
В предлагаемом способе операции сушки и сепарации совмещены, что упрощает техноло0 гию. 34In the proposed method, the operations of drying and separation are combined, which simplifies the process. 34
