Abstract
Изобретение относитс к технике разделений рудного материала в горно-обогатительной технике. Цель изобретени - повышение надежности и долговечности грохота. На раме грохота расположены опорные балки 3 с пазами. В пазах установлены эластомерные карты, из которых выполнено сито грохота и соединенные между собой по торцам посредством выступов и впадин трапециевидной формы, имеющих заплечики 10 и выступы 11с нерабочей стороны карты дл установки в пазах балок 3. Посредством фиксаторов в виде опорных труб 12 с балкой 3 св зан эластомерный брус 4. Кажда труба 12 закреплена в основании лаза балки 3 и размещена в цилиндрическом пазу 5 в нижней части бруса 4. Симметрично пазу 5 расположены выемки 6, в которых размещены стержни 13 круглого поперечного сечени . В верхней части бруса 4 выполнены выемки 14 с ответными заплечиками 15. В выемке 14 расположены соответствующие выступы 11 карты сита. При загрузке грохота рудный материал перемещаетс по рабочей стороне карт сита. В момент максимальной нагрузки на карту сита происходит равномерное распределение нагрузок с одной карты на смежные за счет их соединени по торцам конусными выступами. 1 з.п.ф-лы, 7 ил. (Л СThis invention relates to a technique for separating ore material in a mining and processing industry. The purpose of the invention is to increase the reliability and durability of the screen. On the frame of the screen are support beams 3 with grooves. The grooves are fitted with elastomeric cards, of which a screen is made and interconnected along the ends by means of projections and depressions of a trapezoidal shape, having shoulders 10 and protrusions 11c of the non-working side of the card for installation in grooves of beams 3. By means of clamps in the form of support pipes 12 with beam 3 An elastomer bar 4 is connected. Each pipe 12 is fixed at the base of the manhole of the beam 3 and placed in a cylindrical groove 5 in the lower part of the bar 4. Notch 6 is located symmetrically with the groove 5, in which the rods 13 have a circular cross section and. In the upper part of the beam 4, grooves 14 are made with reciprocal shoulders 15. In the groove 14, corresponding protrusions 11 of the sieve card are located. When the screener is loaded, the ore material moves along the working side of the sieve cards. At the moment of maximum load on the sieve card, there is an even distribution of loads from one card to the adjacent ones due to their connection at the ends with conical protrusions. 1 hp ff, 7 ill.
