Abstract

The device is intended for sorting materials in ore and coal processing plants, in quarries, etc. It consists of an endless belt formed by a pair of Gallium chains, with the ends of the shafts 4 rotatably mounted in the opposite meshes of the chains. Rods 5 are attached to them perpendicular to the longitudinal axis of the shafts 4. Preferably, the shafts 4 are provided with a cam 6 at one end. By gradually changing the position of the rods £, the grate self-cleans.

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for sorting bulk materials based on the principle of an endless belt and solves the problem of efficient and zero-tone sorting of materials of the required grain size.

The sorting of bulk solids into two or more granular grades is of great importance to the technology of their processing, especially in metallurgical processes. It is necessary that each of the classes of granulometric composition be efficiently and effortlessly sorted and separately prepared for processing. Otherwise, the processing efficiency and energy efficiency are reduced. Classical and most commonly used sorting machines with a stable sorting surface, optionally equipped with rounders or vibrators on each or a group of sorting pads placed one below the other or in cascade. rectified vibration and tapping.

Such sorters have low efficiency, especially at elevated humidity, when the sorters of the sorter are sealed without the possibility of accelerating or increasing the sorting efficiency. Such sorters require high, stable and cost-intensive machinery. The problem is partly solved by sifters with fan-shaped or single-sided fasteners. Attempts have also been made to provide a sorting surface in the form of a feed device, for example, according to AO USSR No. 530702, based on a principle-free, partially disintegrating strip formed by grate surfaces between the links of the pulled chains. These surfaces are delimited by wide transverse elements with locks for seating adjacent roots and with a shaft for a separate slide bearing each of the grates. The disadvantage of the solution is that it is not possible to interrelate the grate to each other in the sorting level, the large number of sliding surfaces in the sorting space, which all increases the failure rate.

The operation of the sorter and reduces the efficiency of the sorting. They have a demanding design by the transverse bodies and its parts occupy a large proportion of the sorting surface and are a source of material overload on these elements.

The above mentioned drawbacks are solved and the problem is solved by the device for sorting the bulk materials according to the invention. SUMMARY OF THE INVENTION In the opposite eyes of the double-sided parallel gypsum chain, there are rotatably mounted shafts with fixed grate rods formed in one area of length or two times the distance between the axes of said shafts. they are evenly spaced with axial distances corresponding to the sum of the respective 2 or more times the width of the rod and the selected sorting gap. Preferably, cams are formed at least on one shaft of the shafts against which the solid rounded bumpers of the sprocket are formed with the upper grate level. The limits of the dilution can be chosen in a wide range by selecting the shape and size of the densities and shape of the rods, the second used gypsum chain and the associated drums, and the main drawback of the belt movement, without increasing the width of the sorted material container.

1 shows a schematic diagram of an arrangement of a device with a yard drum, and FIGS. 2 and 3 show an alternative embodiment of a three-way element with two and three folds. bar lengths with shaft markers and bars ·

The drums are made up of pairs of identical gears 1, also rotated, rigidly connected to the shaft 2. Shaft 2 is driven on the drive drum · On the gears JL, parallel gall gears 3 are mounted. the sorting elements consisting of the shafts 4 on which the Si grating rods are attached in parallel, so that the triage elements are in the form of a grate. At one end, the shafts 4 terminated by the cams toward which fixed, rounded bumpers 7 of the amplitude are located at the upper grate level.

The sorting of loose materials on the device according to the invention, formed to accommodate an endless disintegrating grate, takes place just before the material is brought into the tray formed by sorting elements by grate rods 5 composed of viao layers which form a sorting platform which is clean. The grate with the sorted material is shifted by the gall chains 3 in the grinding direction *, with the cam system 6, the individual sorting elements mjurozkyat in the vertical direction, thereby the sorted material is fluffed in the upper branch of the endless line. The underfloor protrudes into the hopper, or onto the discharge belt, and the excessive portion continues in the path down to the drive drum from where it is discharged into a separate hopper or conveyor. The tensile surface breaks down on the drive drum. The rods 5, which have so far been horizontally positioned, have a gradual vertical position, allowing the material to be knocked on the rods 5. In the vertical position, the grate rods 5 remain in the lower branch of the endless belt until a new drum is formed. that the grate bars 5 take the abutment horizontally. The material input needs to be selected so that it does not come close to the gallon chains 3, a guide hopper can be placed from the space between the upper and lower portions of the endless belt to prevent the material from spreading. For use in heavy duty conditions with high retraction, it is advisable that the upper branch of the gall chains 3 be guided on the support rails, similar to the wider classifiers, so that the support rails are also under the shafts 4.

The device according to the invention can be solved in other variants according to the type of material to be sorted and the sorting boundary. For large-sized gaps and hard abrasive materials, shafts 4 and steel alloy rods 5 are suitable for smaller screening gaps and some materials made of steel rolled material. The drive of the drive drum has a variable speed change.

Equipment for Sorting Bulk Materials According to the Invention Suitable in Material Preparation for Technological & outside the blast furnace charge and the like.
