Description

Изобретение относитс к устройствам дл охлаждени кусковых материалов после обжига, спекани или агломерации и может бвть использовано в различных отрасл х производства , например в черной металлургии дл охлаждени агломерата или окатышей в кольцевых охладител х большой единичной мощности.The invention relates to devices for cooling bulk materials after calcination, sintering or agglomeration, and can be used in various production areas, for example, in ferrous metallurgy to cool sinter or pellets in large unit-capacity ring coolers.

Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс кольцевой охладитель агломерата, содержащий кольцевой бункер, закрепленный на разгрузочном столе,- установленном ца тележках , взаимодействующим через цевочное колесо с приводом, состо щим из электродвигател и редуктора, соединенного карданной передачей с механизмом зацеплени , установленным на опоре 1 .The closest to the proposed technical essence and the achieved result is an annular agglomerate cooler containing an annular bunker mounted on a discharge table — mounted trolleys interacting through a pinwheel with a drive consisting of an electric motor and a gearbox connected by a cardan gear to the gearing mechanism mounted on support 1.

Недостаток известного охладител заключаетс в том, что их приводы обеспечивают необходимую надежность при сравнительно небольших размерах зубчатых колес, до 5 м.A disadvantage of the known cooler is that their drives provide the necessary reliability with relatively small gear wheels, up to 5 m.

Дл охладителей большой единич.ной мощности диаметр, зубчатого венца должен быть пор дка 30 м. Практически их нельз изготовить с высокой точностью зацеплени , так как это технически и экономически нецелесообразно . Поэтому детали таких размеров выполн ют составными, но при этом резко ухудшаетс точность .зацеплени составного колеса с шестерней .For coolers of large unit power, the diameter of the ring gear must be in the order of 30 m. Practically, they cannot be made with high precision gearing, since it is technically and economically impractical. Therefore, parts of such dimensions are made integral, but the accuracy of the linking of the composite wheel with the gear wheel deteriorates sharply.

Цель изобретени - повышение надежности .The purpose of the invention is to increase reliability.

Claims

FIG. 1 shows a ring cooler, in plan; in fig. 2 - disconnect AA: in FIG. (element of cooling body with drive); in fig. 3 is a view along arrow B in FIG. 2 (an engagement mechanism). The cooler contains an annular hopper 1 mounted on the unloading table 2 mounted on those deck chairs 3 moving in a circular path. A gear ring 4 with skid tracks 5 is attached to the carts in the outer diameter. Vienna. with tracks made of composite of individual. sectors. The drive of the cooler consists of an electric motor 6, a reducer 7 / connected by a cardan drive 8 with an engagement mechanism 9 mounted on a movable support 10. An engagement mechanism. consists of a cage 11, in which on the axis 12, connected with s. cardan drive 8, rigidly planted pinwheel gear. 13 and copying rollers 14, One side of the 11-week-old on T5 (15 with clamped spring 16. Tha 15 is pivotally connected to the stationary rack 17, The other side of the yoke is pivotally connected with the stand 18. The cooler works the next time. ..... The drive is engaged and the cooler comes into rotation through the engagement mechanism. The gear 13 is engaged with the rim 4, and the rollers 14, being in contact with the digging tracks 5, ensure the transmission of gearing line, in the case of a line of engagement from the hermetic th form, which is permissible: according to the conditions of manufacture of large-sized equipment, copier tracks - gear mechanism of engagement. The yoke 11 on the movable support 10 rotates relative to the hinge of the rack 18 at some angle. However, the gearing of the gear 13 with the crown 4 is not broken as the spring 16 presses Constantly, the clip 11 with a certain force, corresponding to the spacer, will strengthen the engagement. Thus, the inaccuracies of the composite crown 4 are compensated for by the floating engagement mechanism 9, which ensures reliable operation of the cooler. The proposed cooler improves the technical and economic indicators of the process of cooling the agglomerate on operating sintering machines and with their new construction here by increasing the reliability, simplicity of manufacturing, installation and maintenance, as well as reducing the specific capital, costs and saving production. . . Capital costs for the proposed cooler are 2.2 times less than for the known ones. . The proposed cooler occupies 2 times less production area than the known one. Formula of the invention Ring cooler of lump materials containing ring hopper mounted on the unloading table mounted on carriages interacting via a pin wheel with a drive consisting of an electric motor and a gearbox connected by a cardan gear with a hooking mechanism mounted on supports and of tea and tea in order to increase reliability, the gearing mechanism is made in the form of a pinion gear and copy rollers mounted in the cage, one side interacting with the spring oh draft type and the other - is pivotally connected to the fixed axis, the support engagement mechanism is movable.
