Abstract

Изобретение относитс к грохочению сыпучих материалов и м.б. использовано в горно-рудной, металлургической отрасл х пром-сти, строительстве и др. Цель - повышение эффективности грохочени . На стенках короба 1 посредством концевых опор (КО), расположенных под углом к горизонтальной плоскости в продольном направлении грохота, закреплено сито (С) 3. На С 3 вдоль продольной оси грохота закреплена балка (Б) 10. Вибровозбудителем 4, св занным с Б 10, возбуждаютс колебани С 3. Под действием вибрации частицы материала перемещаютс вдоль С 3. Траектори их движени имеет зигзагообразную форму за счет установки участков С 3, расположенных по обе стороны от Б 10, с наклоном вниз от КО к Б 10. Дл обеспечени равномерного распределени частиц по С 3 при грохоче- нии влажных материалов Б 10 закреплена под углом к плоскости, в которой расположены КО. В качестве С 3 м.б. применены наборы эластичных элементов. 2 з.п.ф-лы, 10 ил. ел сThe invention relates to the screening of bulk materials and m. used in the mining and metallurgical industries, construction, etc. The goal is to increase the efficiency of screening. A sieve (C) 3 is fixed on the walls of the box 1 by means of end supports (CC) at an angle to the horizontal plane in the longitudinal direction of the screen. Beam (B) 10 is fixed to C 3 along the longitudinal axis of the screen. 10, oscillations of C 3 are excited. Under the action of vibration, the particles of the material move along C 3. The trajectory of their movement is zigzag-shaped due to the installation of C 3 sections located on both sides of B 10, sloping downward from the CO to the B 10. hour allocation egg 3 to C at grohoche- SRI moist materials B 10 is fixed at an angle to the plane in which are located the DA.

Claims

Claim

1. A screen containing a box, a sieve, mounted on the side walls of the box by means of end supports located at an angle to the horizontal plane in the longitudinal direction of the screen, and a vibro-driver for direct excitation of transverse vibrations of the sieve, about τη and the fact that . in order to increase the efficiency of screening, the screen is equipped with a beam fixed on a sieve to drive the longitudinal axis of the screen and connected to the vibration exciter, and whitefish sections located on both sides of the beam are installed with an inclination downward from the end supports to the beam,

2. The screen according to claim 1, characterized in that the beam is fixed at an angle to the plane in which the end supports of the screen are located.

3. Rumble pop. Gotlichychsya 'the fact that the sieve is made at least at the discharge end of the rumble in the form of a set of elastic elements.
