SU847900A3 - Device for sorting particles of grained material - Google Patents

Abstract

A sizing device, for classifying particles, comprises a frame which is substantially rhombic in side elevation or vertical longitudinal section, and carrying a number of screens, bars, or similar elements having openings larger than the arriving particles. Vibrating means are secured to the frame beneath the screens or the like and symetrically with respect to the shorter diagonal of the substantially rhombic frame, so that the space above the topmost screen is free and substantially unobstructed.

Description

154) DEVICE FOR SORTING GRAINED PARTICLES The invention relates to devices for sorting particles of granular materials. Devices for sorting particles of granular materials are known, which contain a frame suspended on shock absorbers, consisting of front, rear and side walls, vibrated from vibrators, carrier gratings with openings attached to it, inclined one above the other. Type vibrators mounted IB top of the l. The disadvantages of these devices are that the space between the base of the vibrator and the upper grill limits the maximum dimensions of the material particles supplied and also that this space cannot be used, for example, for loading. In addition, when a hot material is fed into the device, the vibrators are subjected to undesirable heat. It is also known a device for sieving material particles, in which a frame with gratings is set in oscillatory motion from a vibrator, distributed by MATERIAL, in the lower part of the device outside the frame G2. However, these devices also do not provide a uniform mode of operation, which depends on the size and position of the vibrating mass of the sorbed material, which varies during operation, which usually leads to an uneven material supply process. The purpose of the invention is to ensure uniform operation. This is achieved by the fact that the vibrators are located inside the frame under the gratings, and the side walls of the frame are made of rhombic shape, while the vibrators are attached to the transverse wall, which is rigidly attached to the side walls of the frame perpendicular to the latter and is located in the direction of vibration along the smaller diagonal of the rhombic side wall Vibrators should be positioned symmetrically on both sides of the transverse wall. FIG. 1 a device is given, a longitudinal section in FIG. 2 is the same, the view from the signal of FIG. 3 is the same, a side view.

Claims _t 1. A device for sorting particles of granular material, containing a frame suspended on shock absorbers, consisting of a front, rear and side walls, driven by 5 movement from the vibrators, carrying lattices with holes attached to it, inclined one above the other, characterized in that, in order to ensure uniform operation, the vibrators are located inside the frame under the lattices, and the side walls of the frame are made in rhombic shape, while The vibrators are attached to the transverse wall, which is rigidly attached to the side walls of the frame. The perpendiators are located symmetrically on both sides of the transverse wall. Vibrators are protected from material by plate 15. The device operates as follows. The material to be sorted is fed into the space 16 at the top of the device. When the frame is oscillating, the material moves along the gratings 7-1'1 and is removed through the outlet openings of each of them. angles to the latter and extends in a direction along the vibration at the diagonal side rhombic sten20 ^ki · 2. The device according to. p. 1, characterized in that the vibrators are located symmetrically on both sides of the transverse wall.
