Abstract

Изобретение относитс к вибрационному разделению сыпучих смесей и м.б. использовано в литейной, строительной и других отрасл х промышленности. Цель - повышение эффективности грохочени и улучшение условий обслуживани или замене сит. Грохот содержит короб, закрепленные на его боковых стенках 6 и 7 направл ющие /Н/ 4 и 5, на которых болтами 11 закреплено сито /С/ 3. На нижней поверхности С 3 выполнены бобышки 10 с резьбовыми отверсти ми, в которые вворачиваютс болты 11 креплений. Поверхности Н 4, 5, на которых установлено С 3, расположены под углом вниз, а в боковых стенках 6, 7 выполнены окна 12, через которые осуществл ют крепление болтами 11. При демонтаже С 3 через окна 12 отворачивают болты 11 и по Н 4, 5 перемещают С 3 в сторону загрузочного или разгрузочного концов короба. Благодар бобышкам 10 между С 3 и Н 4, 5 существует зазор, в который просыпаетс подрешетный продукт, и по наклонным поверхност м Н 4, 5 скатываетс вниз. 3 ил.The invention relates to the vibration separation of bulk mixtures and m. used in the foundry, construction and other industries. The goal is to increase the efficiency of screening and to improve service conditions or to replace sieves. The screen contains a duct, guides / H / 4 and 5 mounted on its side walls 6 and 7, on which bolts 11 secure a sieve / C / 3. On the lower surface of C 3, lugs 10 are made with threaded holes into which bolts 11 are screwed. mounts. Surfaces H 4, 5, on which C 3 is installed, are angled downward, and in side walls 6, 7 windows 12 are made, through which bolts 11 are mounted. When C 3 is dismantled, bolts 11 and H 4 are unscrewed through windows 12 5 move C 3 towards the loading or unloading ends of the box. Thanks to the lugs 10, there is a gap between C 3 and H 4, 5 into which the undersize product spills, and on the inclined surfaces H 4, 5 rolls down. 3 il.

Claims

Claim

Vibrating screen, including a box, guides fixed on the side walls of the box, on which a sieve is installed with its lateral edges and secured to them by bolt connections, characterized in that, in order to increase screening efficiency and improve service conditions when replacing screens, the sieve is made with bosses located on its lower side in the places of installation of bolt fasteners, the surfaces of the rails on which the sieve is installed are located at an angle downward, and in the side walls of the box, in places dix bosses formed window, wherein in bosses formed threaded holes, which are associated with the sieve fixing bolts.
