Description of the invention

The subject of the invention is a municipal waste separation system, especially in households and infrastructure facilities that do not produce hazardous waste. Nowadays, the constantly increasing amount of municipal waste collected in a relatively small storage area causes a negative impact on the natural environment, therefore, before its final disposal in a landfill, it is subjected to segregation, physical, biological or other transformation.

A system of a fine fraction recovery station is known, used by the producer of the waste sorting plant, comprising a feed conveyor provided at the beginning with a bin and reaching above the screen of the vibrating screen, under which the beginning of the first discharge conveyor is placed, and the material from above the screen of the vibrating screen falls to the beginning of the second conveyor . The bunker in front of the outgoing conveyor is placed above the conveyor in its axis. The recovery of the fine fraction is transferred via the first discharge conveyor directly to the trailer of the transport vehicle. The second discharge conveyor is positioned perpendicular to the axis of the discharge conveyor.

In order to obtain greater economic use of municipal waste, a separation system has been developed to increase the efficiency of disposal.

The system according to the invention consists of a double-deck vibrating screen with an upper screen deck connected in series with the outgoing conveyor at the entrance and at the exit in series with the ballast conveyor and the lower screen deck connected at the exit in series with the ballast conveyor and parallel to the bottom with the under / screen conveyor the ballast conveyor feeds the oversize fraction of the manual sorting cabin.

The advantage of the system according to the invention is the possibility of obtaining three waste fractions locally, reduced landfill occupancy, use of waste for compost as alternative fuels, low operating cost and small size of the system.

The subject of the invention is shown in the drawing in the form of a circuit diagram in the drawing.

As shown in the figure, municipal waste consisting of a mixture of secondary raw materials, bio-waste and other raw materials is loaded into the hopper 1 at the beginning of the outfeed conveyor 2 and fed to the double-deck vibrating screen A, where it is separated on the upper sieve deck 3 into fractions from 0-100 mm and the lower sieve deck 4 for fractions from 20-100 mm and a fraction from 0-20 mm, with a slope of 3.4 parallel sieves at an angle of 15 ° to the horizontal. The fraction of waste over 100 mm obtained on the sieve deck 3 is fed to the ballast conveyor 6 passing through the center of manual sorting booths 5, in which material is separated into containers 7 for recycling from the remaining 8.

A waste fraction with dimensions of 20-100 mm obtained from the part of the feed stream retained on the lower sieve deck 4 is fed to the ballast conveyor 9 and directed to the place of placement 10, the final part of the feed in the form of a waste fraction of 0-20 mm drops vertically straight to the under-screen conveyor feeding the fraction to its location 12, intended for economic use. Preferably, in the system according to the invention, a set of additional known devices for grinding, baling, compacting waste components 13 allows for greater recycling of waste, and thus for reducing the area of the landfill 14, to the area necessary for the storage of unsuitable waste, meeting the postulate of minimizing the nuisance to the environment. .

Claims (2)

Patent claims 1. Municipal waste separation system including conveyors and manual sorting cabins, characterized by the fact that it is equipped with a double-deck vibrating screen (A) with an upper sieve deck (3) connected in series with the outgoing conveyor (2) at the entrance and with a ballast conveyor (6) at the exit (6). ) and a lower screen deck (4) connected at the exit in series with the ballast conveyors (9) and parallel from the bottom to the under screen conveyor (11), the ballast conveyor (6) passing through the manual sorting booths (5). PL 210 797 B1 2. The system according to claim 3. A method as claimed in claim 1, characterized in that the preferably parallel sieves (3, 4) produce three waste fractions with a size greater than 100 mm, from 0-100 mm and from 0-20 mm, with an inclination of 5 ° -25 ° to the horizontal.
