Description

The invention relates to devices for the hydraulic classification of materials, in particular for the separation of hedge-waste in enterprises of the agro-industrial complex, and is an improvement of the invention according to apt. No. 1155293.

The purpose of the invention is to improve the quality of sorting and increase productivity,

FIG. t depicts a chamber hydraulic classifier, top view; FIG. 2 is the same longitudinal section; FIG. 3 is a section A-A in FIG. 1;

The classifier contains a receiving chute 2 installed in the housing 1 and classifying chambers 3-5, a loading device 6 located above the adjacent chute, a water circulation system formed by the grate 7 and a conduit 8 connecting the chamber 4 with the receiving chute 2 in which the screw 9 is installed. The lower part of chamber 5 has an inclined conveyor iO, and in the lower part of chamber 3 there is a screw conveyor 11. Above the grate 7 there is a shaft 12 with the fingers 13 attached to it, and the grate 7 itself is mounted at an angle to the end wall of the housing L and connected to the threshold 4, installed flush with the receiving chute 2, the Additional screw 15 is installed parallel to the screw 9 of the receiving chute 2, and the channel 16 of the additional screw 15 is connected to the lower part; 1; pivoting guide plates 17, the scraper conveyor 18 is installed in the middle chamber 3, and its intake part is installed below. The intake part of the screw conveyor 11 eshetka 19,

Classifier works as follows.

Before starting work, case 1 is filled with water up to the level of drain threshold 14. When screws 9 and 15 are inserted, a closed flow is created in the classifier (in FIG. 2 the 3rd is shown

58485. 2

arrows) - water is supplied by screws 9 and 13 to chamber 5, then to chambers 3 and 4 and directed through grate 7 to conduit 8 forming the walls of chambers 5, 3 and 4 and housing 1 of class 1, which returns to chute 2 and 16, moreover, if a screw 9 creates a horizontal flow through the chambers 5,

 3 and 4, the flow from the screw 15 along the chute 16 is supplied to the lower part of the chamber 5, the movement of this flow is corrected by the guiding rotary plates 17, then the flow from the screw 5 and 15 is poured into the flow from the screw 9,

The material to be separated - food waste - is fed by the loading device 6 to the receiving chute 2. During operation of the screw 9,

20 disintegrating food waste and moving through the upper part of chamber 5 into chamber 3, in chamber 5, heavy non-edible inclusions (metal, stones, bones, ceramics, etc.) are separated, and the flow from the auger is prevented from precipitating the food part. 15, the bottom 5 of the chamber 5 and the guiding plates 17, T, which are non-food inclusive, are removed from the chamber 5 by a 30-sided conveyor 10,

Then, with the water flow, food waste in the mode of a submerged jet is subjected to hydraulic classification in chamber 3, the feed section from 35 moves with a specific gravity greater than water, settles to the bottom of chamber 3 and is removed by a screw conveyor 11. Fibrous (textiles. Twine, ropes) non-fodder inclusions with a specific height more than that of water, (due to swelling) are deposited on an additional grate 19 and are periodically removed by the operator manually. Floating non-fodder inclusions (polyethylene, paper, textiles) are introduced into the chamber 4 by the flow of water, where they are retained on the grate 7 and removed when the shaft 12 rotates with the loose fingers 13 through

50 a drain threshold 14. Small non-edible inclusions (sand, glass, metal, ceramics, etc.) are deposited on the intake portion of the scraper conveyor 18 and removed.
