Description

The invention relates to a technique for sorting grain milling products, namely, sieve frames for sieving, and can be used in flour mills in the grain processing industry and in agricultural production mills.

A known circular sieve sieve frame, comprising a horizontal sieve and a bottom, attached to a frame divided into sections in which the sieve cleaners 1 are placed.

The disadvantages of this device are bulkiness and mass.

Closest to the invention to the technical essence and the achieved result is a sieve frame for sowing with circular motion, including a sieve, inertial cleaners located under the sieve, and the supporting frame 2.

A disadvantage of the known device is the complexity of the design. In addition, the manufacture of the bearing frame in the presence of a large number of fasteners leads to an increase in the cost of manual labor. The aim of the invention is to simplify the design, reduce the cost of its manufacture and facilitate manual labor.

This goal is achieved by the fact that in a sieve frame for sowing with circular motion, including a sieve, inertial cleaners located under the sieve and a supporting frame, the latter is made in the form of a single-stamped trapezoidal section trough facing its sieve and equipped with Self-end flanging, perpendicular to the bottom.

FIG. 1 and 2 show the sieve frame for siftings with circular motion, general view; in fig. 3 - section aa-a to fig. 2; in fig. 4 - bearing frame sieve frame, view in plan; in fig. 5 is a section BB in FIG. four; in fig. 6 - sieve frame with frame, installed in the sieve shkafu; in fig. 7-section B-B in FIG. 6. The circular sieve sieve frame includes a rectangular sieve frame 1 consisting of wooden bars 2-5 with a sieve fixed on them 6. The sieve frame 1 is inserted 8 supporting frame 7 which serves as a support for it and for from food rubber inertial cleaners 8 of the vagus type, intended for cleaning the sieve 6 of the sieve frame 1 and at the same time for removing from the frame 7 the pass-through fraction of the product passing through the sieve 6. The frame 7 is made as a single stamped from a single aluminum billet Trapezoidal eloba with its small bottom 9 up

the sieve 6. The bottom 9 is formed from a horizontal plane 10 and adjacent two inclined planes I and 12. The plane 10 is intended to support the sieve frame 1 and the product fraction from under the sieve 6. The planes 11 and 12, the angle to the horizontal is 30 °, are intended for discharge from the plane 10 of the passage fraction into the side vertical channels of the screening screen. The trapezoidal shape of the gutter facing the sieve on a small bottom increases the rigidity of the frame 7, which makes it possible to manufacture the frame 7 from a 1-mm-thick all-metal sheet and simplify the production of the frame.

Planes 11 and 12 are reinforced at both ends by flanges 13-16, which, together with an increase in the rigidity of the frame 7, are intended to facilitate removal of the frame together with the screen. The bottom 9 by means of vertical walls 17 and 18 is connected to

horizontal shelves 19 and 20 for mounting the frame 7 and the sieve frame 1 with a sieve 6. The frame 7 is provided with flanges 21 and 22 at both ends, perpendicular to the bottom 9, and intended for fixing the sieve frame 1 with a sieve 6 in the frame 7. Sitova The assembled frame 23 is located in the sifting cabinet 24, supported by the shelves 19 and 20 of the frame 7 on the rails 25 and 26 of the cabinet 24, and is positioned above the underlying sieve frame

27. In this case, the inclined planes 11 and 12 of the frame 7 are located opposite the slots 28 and 29 formed in the walls 30 and 31 of the cabinet 24 and intended to release the passage fraction of the product from the planes 11 and 12 into the longitudinal vertical channels 32

and 33 cabinets 24 sieving. A vertical channel 34 of the cabinet 24 with an overflow partition 35 is provided for the tailing fraction, on the opposite side the cabinet has a similar vertical channel 36 s

partition wall 37

Sieve frame for sowing with circular motion works as follows.

The initial mixture of grain milling products to be sorted enters

from above on the sieve 6 from the side of the flange 21 and under the action of the bulk head arising from the circular movement of the frame, moves along the sieve 6 in the direction of the flange 22.

„

In the process of moving the original mixture

it is sorted into a coarse gathering fraction, which is poured from sieve 6 through flanging 22 into vertical channel 34 and further, onto partition 35 and poured into sieve of underlying frame 27 for further sorting. The passage fraction is sifted through a sieve 6 onto a trapezoid bottom 9 facing the sieve 6. From the plane 10, the pass fraction along the inclined planes 11 and 12 is poured down and out through slots 28 and 29 into vertical longitudinal channels 32 and 33 of the sifting cabinet 24 for further processing.

Thus, making the frame in the form of an all-stamped trapezoidal section gutter, improved by its small bottom to the sieve and provided with flanges perpendicular to the bottom at both ends, simplifies the design, reduces its manufacturing cost and eases the manual labor of the service personnel.
