Description

Изобретение относится к технике измельчения материалов, в частности к измельчителям для разделки проводников тока на предприятиях вторичной цветной металлургии.The invention relates to techniques for grinding materials, in particular to grinders for cutting current conductors at secondary non-ferrous metallurgy enterprises.

Известен' роторный измельчитель для проводников тока типа ИПР, состоящий из цилиндрической камеры резания с разгрузочной решеткой и загрузочным окном. Внутри цилиндрической камеры находится ротор с закрепленными на нем ножами. Поступающие небольшими пучками (порциями) через загрузочное окно проводники тока попадают в зону действия вращающихся ножей, разре- ₍заются ими на мелкие куски и высы- паются через разгрузочную решетку [ϊ].Known 'rotary grinder for current conductors of the IPR type, consisting of a cylindrical cutting chamber with a discharge grill and a loading window. Inside the cylindrical chamber there is a rotor with knives fixed on it. Applicants small beams (portions) through the loading hole current conductors enter the action of rotating blades zone razre- _(zayutsya them into small pieces and vysy- Payuta through the discharge grille [ϊ].

В известном измельчителе резание проводников тока производится по параллельным линиям, однако для лучшего измельчения проводников тока и снятия с них изоляции резание пучка целесооб2 разно производить в различных пересекающихся плоскостях.In the well-known grinder, the cutting of current conductors is carried out in parallel lines, however, for a better grinding of the current conductors and removing insulation from them, it is expedient to cut the beam in different intersecting planes.

Наиболее близким техническим решением к предлагаемому является планетарный измельчитель,, преимущественно для проводников тока в полимерной изоляции, включающий наклонно установленную сферическую рабочую камеру, состоящую из двух полусфер, одна из которых имеет возможность вращения и снабжена внутри валом с ротором, причем вал жестко соединен с неподвижной полусферой посредством конической передачи [2].The closest technical solution to the proposed one is a planetary chopper, mainly for current conductors in polymer insulation, including an obliquely mounted spherical working chamber, consisting of two hemispheres, one of which is rotatable and provided with a shaft with a rotor inside, and the shaft is rigidly connected to a fixed hemisphere through a bevel gear [2].

Недостатком этого измельчителя является неэффективность измельчения материала. Это обусловлено слабым подпором материала (проводников тока) в процессе резания, в результате чего измельчаемый материал, находясь против режущей кромки ножа, может вращаться вместе с режущей кромкой не перерезываясь. При этом производительность измельчителя падает, аThe disadvantage of this grinder is the inefficiency of grinding material. This is due to a weak backing of the material (current conductors) during the cutting process, as a result of which the crushed material, being against the cutting edge of the knife, can rotate without cutting along with the cutting edge. At the same time, the performance of the grinder falls, and

88472А удельные энергозатраты на измельчение увеличиваются.88472A specific energy consumption for grinding increases.

Цель изобретения — повышение эффективности процесса измельчения.The purpose of the invention is to increase the efficiency of the grinding process.

Указанная цель достигается тем, что планетарный измельчитель, включающий наклонно установленную сферическую рабочую камеру, состоящую из двух полусфер, одна из которых имеет возможность вращения и снабжена внутри валом с ротором, причем^вал жестко соединен с коническим сателлитом, снабжен дополнительным ротором, свободно установленным на валу, и коническим сателлитом, жестко соединенным с дополнительным ротором, при этом роторы выполнены с возможностью противоположного вращения,.·This goal is achieved by the fact that the planetary shredder, which includes an oblique mounted spherical working chamber, consisting of two hemispheres, one of which is rotatable and provided with a shaft with a rotor inside, and the shaft is rigidly connected to a conical satellite, equipped with an additional rotor freely mounted on shaft, and a conical satellite rigidly connected to the additional rotor, while the rotors are made with the possibility of opposite rotation,. ·

На фиг. 1изображен измельчитель, общий вид; на фиг. 2 — разрез А-А фиг. 1.In FIG. 1 shows a chopper, general view; in FIG. 2 is a section AA of FIG. 1.

Планетарный измельчитель состоит из сферической камеры 1 резания, выполненной из двух полусфер: нижней вращающейся полусферы 2 с разгрузочной колосниковой решеткой 3 и верхней неподвижной полусферы 4 с загрузочным окном 5. В нижней полусфере установлен составной аал. 6, на левой части которого жестко закреплен основной ротор 7 й свободно насаженный на правой части вала дополнительный ротор 8 с режущими органами (серповидными ножами) 9. Для. лучшего измельчения проводников тока и снятия с них изоляции предусмотрена как шарнирная подвеска серповидных ножей к ротору, так и их жесткое крепление в средней части рабочей камеры при помощи болтового соединения.The planetary grinder consists of a spherical cutting chamber 1 made of two hemispheres: a lower rotating hemisphere 2 with a discharge grate 3 and an upper fixed hemisphere 4 with a loading window 5. A composite aal is installed in the lower hemisphere. 6, on the left side of which the main rotor 7 is rigidly fixed; the additional rotor 8 freely mounted on the right side of the shaft 8 with cutting organs (sickle-shaped knives) 9. For. better grinding of current conductors and removing insulation from them is provided for both the hinged suspension of sickle-shaped knives to the rotor and their rigid fastening in the middle part of the working chamber by means of a bolted connection.

Внутренние полости верхней и нижней полусфер образуют сферическую камеру резания проводников, радиус которой немного больше длины наибольшего серповидного ножа. На конце ножевого вала 6 вне камеры резания жестко насажен конический сателлит 10, а на конце дополнительного ротора.8 жестко насажен дополнительный конический сателлит 11, которые совместно с неподвижным коническим колесом 12 и нижней чашей 2, служащей водилом, составляют коническую планетарную передачу, предназначенную для сообщения сёрпрвидным ножом сложного вращательного движения;The internal cavities of the upper and lower hemispheres form a spherical chamber for cutting conductors, the radius of which is slightly larger than the length of the largest sickle knife. A conical satellite 10 is rigidly mounted on the end of the knife shaft 6 outside the cutting chamber, and an additional conical satellite 11 is rigidly mounted on the end of the additional rotor. 8, which together with the fixed conical wheel 12 and the lower bowl 2 serving as a carrier make up a conical planetary gear intended for messages with a hard knife of a complex rotational movement;

Измельчитель работает следующим образом.The chopper works as follows.

При вращений нижней полусферы 2 конические сателлиты 10 и 11, а следовательно и основной 7 и дополнительный 8 роторы с закрепленными на 5 них ножами, вращаются вокруг оси ножевого вала в противополржных направлениях. Ножи при этом вращаются вокруг, оси ножевого вала 6, а также совместно с ножевым валом вокруг оси 10 камеры 1 разания,т.е.совершают сложiHoe вращательное движение во взаимно перпендикулярных плоскостях.Поступающие на измельчение через загрузочное окно проводники тока попадают в зону 15 действия вращающихся в противпоЛожных направлениях ножей, заклиниваются между режущими кромками средних, движущихся навстречу друг другу., серповидных лезвий (фиг. 2) и разреза20 юТся, предотвращая тем самым проворачивание измельчаемого материала без резания.'During the rotation of the lower hemisphere 2, the conical satellites 10 and 11, and consequently the main 7 and additional 8 rotors with knives fixed on 5 of them, rotate around the axis of the knife shaft in opposite directions. In this case, the knives rotate around the axis of the knife shaft 6, as well as together with the knife shaft around the axis 10 of the chamber 1, i.e. they perform complex rotational motion in mutually perpendicular planes. The current conductors received for grinding through the loading window fall into the action zone 15 knives rotating in opposite directions are jammed between the cutting edges of the middle, moving towards each other., sickle-shaped blades (Fig. 2) and cut 20 yuta, thereby preventing the grinding material from turning without cutting. '

Claims

The invention relates to engineering and grinding of materials, in particular, to crushers for cutting current conductors in enterprises of secondary non-ferrous metallurgy. A known rotor chopper for current-carrying conductors of the IPR type, consisting of a cylindrical cutting chamber with a discharge grid and a loading window. Inside the cylindrical chamber there is a rotor with knives fixed on it. The current conductors entering in the zone of action of the rotating knives, entering in small beams (portions) through the loading window, are cut into small pieces and ejected through the discharge grid 1. In a known chopper, the cutting of current conductors is carried out along parallel lines, however, to better crush and isolate the current conductors, beam cutting is expediently carried out in different intersecting planes. The closest technical solution to the proposed is a planetary chopper, mainly for current conductors in polymer insulation, including an obliquely mounted spherical working chamber consisting of two hemispheres, one of which is rotatable and provided inside with a rotor pdM, and the shaft is rigid connected to a fixed hemisphere by means of a bevel gear 2. The disadvantage of this shredder is the inefficiency of grinding material. This is due to the weak backing of the material (current conductors) during the cutting process, as a result of which the material to be ground, being against the cutting edge of the knife, can rotate together with the cutting edge without being cut. At the same time, the productivity of the shredder decreases, and the specific energy consumption for the reduction increases. The purpose of the invention is to increase the efficiency of the grinding process. This goal is achieved by the fact that a planetary mill, including an obliquely mounted spherical working chamber consisting of two hemispheres, one of which is rotatable and provided inside with a rotor shaft, and the shaft is rigidly connected to a conical satellite , provided with an additional rotor, freely mounted on the shaft and a conical satellite rigidly connected to the additional rotor, while the rotors are designed to be opposite th rotation ..Na FIG. 1 depicts a shredder general view; in fig. 2 - section A-A of FIG. 1. A planetary chopper consists of a spherical cutting chamber 1 made of two hemispheres: a lower rotating hemisphere 2 with an unloading grate 3 and an upper fixed hemisphere k with a loading window 5. A composite shaft is installed in the lower hemisphere. 6, on the left side of which the main rotor 7 is rigidly fixed and the additional rotor 8 mounted freely on the right side of the shaft with cutting bodies (sickle-shaped knives) 9. For. better shredding of the current conductors and removal of the insulation from them; both the hinge suspension of sickle-shaped knives to the rotor and their rigid attachment in the middle part of the working chamber by means of a bolted joint are provided. The internal cavities of the upper and lower hemispheres form a spherical chamber for cutting conductors, the radius of which is slightly longer than the length of the largest crescent knife. At the end of the cutter shaft 6, a conical satellite 10 is rigidly mounted outside the cutting chamber, and an additional conical satellite 11 is rigidly mounted at the end of the additional rotor.8, which, together with the stationary conical wheel 12 and the lower bowl 2 serving as a carrier, form a conical planetary gear designed to communicate a cusp for a complex rotary movement; The chopper works with; 1 the following way. During the rotations of the lower hemisphere 2, the conic satellites 10 and 11, and therefore the main 7 and additional 8 rotors with knives fixed on them, rotate around the axis of the knife shaft in anti-directional directions. In this case, the knives rotate around the axis of the knife shaft 6, as well as together with the knife shaft around the axis of the chamber 1, i.e. perform a Rotary rotational movement in mutually perpendicular planes. Current conductors entering the grinding through the loading window the knives rotating in opposite directions are wedged between the cutting edges of the middle moving towards each other, sickle-shaped blades (Fig. 2) and cut, thereby preventing the material to be ground being turned without cutting. The technical advantages of the proposed planetary dredger consist in increasing the efficiency of the process of grinding current conductors, which is expressed in reducing the specific energy consumption for cutting them by about 20-30% and in increasing the productivity of the shredder. The invention of a planetary mill, mainly for current conductors in polymer insulation, includes an inclined mounted spherical working chamber consisting of two hemispheres, one of which is rotatable and provided inside with a shaft with a rotor, and the shaft is rigidly connected to a conical satellite, differing in that, in order to increase the efficiency of the grinding process, the grinder is equipped with an additional rotor mounted on the shaft freely, and with a conical satellite rigidly connected to lnym rotor, the rotor being configured to counter-rotating.
