Abstract

The invention is intended to separate loose mixtures and may be used to clean and calibrate seed. The purpose of the invention is to provide a multi-fractional separation of bulk material. For this purpose, wringer rollers 6 are installed above the working branch of the endless flexible band (CH) 1 of the separator to form curvilinear sections on it with a curvature that sequentially increases from the initial section. Perpendicular to the surface of the PG 1, the separating elements in the form of fingers (P) 3 are fixed on it in a checkerboard pattern. The distance between the P 3 is equal to the size of the smallest seed. Seeds with impurities are supplied by conveyor 5 under the initial section of GL 1. When passing from a curved section to a straight line, seeds of P 3 are clamped and transported by GL 1. Non-squeezed seeds and impurities are dumped into collection 8 under the conveyor 5. With further transportation on curvilinear sections GL 1 with acc. Decompressing P 3, intermediate fractions fall out into additional receivers 9 installed under the working branch of CH 1 at the locations of rollers 6. 1 sludge. (L oo o 00 with with C71 N in

Description

The invention relates to a device for separating loose mixtures, can be used for cleaning and calibrating seeds, and is an improvement of the device according to the author. St. No. 1132988.

The purpose of the invention is to provide a multi-fractional separation of bulk material.

The drawing depicts a principle

on the separator circuit for cleaning bulk material.

The separator consists of an endless flexible belt 1 mounted on shafts 2. On the belt 1 perpendicular to its surface, dividing elements in the form of pins 3, made of an elastic material with spherical thickenings at the ends, are fixed in a checkerboard pattern. The distance between the fingers is equal to the size of the fur seed itself. The separator is equipped with a feeder 4 of the initial mixture, the latter having a feeding conveyor 5, the final section of which is located under the initial section of the working branch of the mite parallel to it. The spacing between the surface of the conveyor and the flexible tape can be equal to the length of the fingers. Wringer rollers 6 are installed between the shafts 2 above the working branch of the flexible tape. Under the end section of the endless flexible tape 1, a receiver 7 is installed for the seed fraction of the largest

size and receiver 8 for fraction 35 with a bath while bending around the shaft 2 with impurities of coarse and fine dimensions j additional receiver 9 (the number of such receivers is equal to the number of squeezing rollers) for fractions of seeds intermediate between the minimum and 40 maximum sizes is installed under the working branch of the flexible tape . To clean the tape 1 from particles that are accidentally stuck between the fingers, a comb 10 type cleaner is installed. The rollers 6 45 are installed with the formation on the working branch of curvilinear parts with a curvature that gradually increase from the initial section.

the end of the working branch of the tape 1; Larger than the seed particles are not clamped between the fingers due to the large angle of the fingers from the perpendicular position to the plane of the endless tape and at the end of the conveyor 5 is dropped down.

Invention Formula Separator for cleaning bulk material according to ed. St. No. 1132988, characterized in that, in order to provide multifractional separation of bulk material, it is equipped with squeezing rollers J installed above the working branch of a flexible tape with the formation of curvilinear sections with curvature on it, sequentially increasing from the initial part, and additional receivers of fractions installed under the working section branch of flexible tape in the locations of the squeezing rollers. The separating elements can be made in the form of rectangular grooves arranged with the longitudinal axis perpendicular to the direction of movement of the tape. The separator for cleaning and calibrating bulk material works as follows. The initial section of the working branch of the flexible tape 1 with separating elements into video finger 3 and the feeding conveyor 5 move in parallel planes in one direction from the feeder 4 of the initial mixture with equal speed; Seeds with impurities are supplied by the conveyor 5 to the curvilinear section of an infinite flexible 5 0 0 five When moving along a curved section, the distance between the ends of the fingers 3 increases and the seeds of the initial mixture enter the space between the fingers. When moving to the straight-line segment, the distance between the ends of the fingers decreases and they clamp the seeds. Smaller fractions than seeds are not clamped and are dropped down at the end of the conveyor. The seeds clamped by the fingers 3 move together with the endless flexible belt 1 to the curvilinear section formed by the rounding-off of the squeezing roller 6. The seeds of a larger fraction fall out on this site. The dropped out seeds move to the next curvilinear section with a greater curvature (only one curvilinear section J formed by the rollers is shown), where an even larger fraction falls out. Itself krz pna fraction of seeds falls out on the curvilinear section formed when the tape bends around the shaft 2 in the end of the working branch of the tape 1; Larger than the seed particles are not clamped between the fingers due to the large angle of the fingers from the perpendicular position to the plane of the endless belt and at the end of the conveyor 5 are dropped down.
