Abstract

Грохот для разделения сыпучих материалов, содержащий просеивающую поверхность, привод, загрузочное и разгрузочное приспособления, отличающийся тем, что просеивающая поверхность упруго установлена на станине, снабжена вибратором и выполнена в форме тора с волнообразной многозаходной винтовой перфорированной поверхностью двоякой кривизны, снабженной винтовыми канавками внутри и наружи перфорированной поверхности под углом к его оси в виде карманов криволинейной формы с центрами кривизны расположенными наружи и внутри поперечного сечения просеивающей поверхности, смонтированы из секций, каждая из которых выполнена в виде кругового сектора, изготовленного из перфорированной полосы, свернутой в кольцо с образованием разных по размерам четырехугольников с двумя параллельными сторонами, расположенными параллельно друг другу, при этом секции соединены друг с другом свободными сторонами упомянутых четырехугольников в виде пустотелой просеивающей поверхности, с образованием по наружной и внутренней поверхностям, направленных в одну сторону под углом к продольной оси просеивающей поверхности ^однообразных винтовых перфорированных поверхностей в виде карманов криволинейной формы по наружной и внутренней поверхностям, которые по периметру просеивающей поверхности могут быть различными не только по форме, но и по размерам, при этом расстояние между линиями сгиба равно сумме длин периметров геометрических фигур карманов внутренней и наружной поверхностей. A screen for separating bulk materials containing a screening surface, a drive, loading and unloading devices, characterized in that the screening surface is resiliently mounted on the bed, equipped with a vibrator and made in the form of a torus with a wave-shaped multi-start screw perforated surface of double curvature, equipped with screw grooves inside and out perforated surface at an angle to its axis in the form of pockets of curved shape with centers of curvature located outside and inside the transverse section of the screening surface are mounted from sections, each of which is made in the form of a circular sector made of a perforated strip rolled into a ring to form different-sized quadrangles with two parallel sides parallel to each other, while the sections are connected to each other by free sides the said quadrangles in the form of a hollow screening surface, with the formation on the outer and inner surfaces, directed to one side at an angle to the longitudinal axis screening surface ^ of uniform screw perforated surfaces in the form of pockets of curved shape on the outer and inner surfaces, which along the perimeter of the screening surface can be different not only in shape but also in size, while the distance between the fold lines is equal to the sum of the lengths of the perimeters of the geometric figures of the pockets of the inner and outer surfaces.
