Description

The invention relates to plants for processing tailings of municipal solid waste and can be used in construction upon receipt of various components for the production of building materials, as well as in road construction.

A device for crushing scrap, as well as industrial and household waste, containing a drive, a housing, two parallel counter-rotating shafts mounted on them with circular knives having cutting teeth, the circular knives of one shaft located in the gaps between adjacent circular knives of the other shaft, formed by means of gaskets between them, and the cutting teeth of the disk knives of each shaft are located along a helical line (Copyright certificate No. 1738345 according to class V02C 18/06 of 06/07/92).

The disadvantage of this device is the low processing efficiency and high material consumption.

The closest technical solution is the installation for processing materials during thermochemical processing, containing a crushing unit, a heat exchanger for drying and heating raw materials, a metering feeder, a hot gas generator with channels, a cylindrical thermo-gas-dynamic chamber of fine grinding and heat treatment of the material with loading and unloading channels and nozzles supply of a gas energy carrier to a group of precipitation cyclones, while the thermogasdynamic chamber is made with tangential nozzles for supplying hot high-speed jets of energetic gas connected by channels to a hot gas generator (Р 2036011, class B02C 19/06, dated May 27, 1995).

The disadvantage of this device is its excessively high energy and material consumption and a rather complicated design.

The technical task of the proposed invention is to simplify the design, improve the ecology of the environment due to the possibility of using recycled solid waste in various industries

The technical problem is ensured by the fact that the installation for processing solid domestic waste tailings contains a pre-treatment unit for materials and a final processing unit communicated with it by the conveyor, while the pre-treatment unit is equipped with a receiving device and a transport system with ferrous and non-ferrous metal detectors with the output of current signals for control executive mechanisms for the selection of metals, and the final processing unit contains a receiving hopper communicated with a high-temperature reactor block for dynamically acting on the material in an electromagnetic field, the unit having a material destruction chamber, a compressed air turbine for cooling the reactor and feeding material through the louvers into the grinding chamber, and a fractional composition output control unit in communication with the outlet flow is installed under the reactor .

The invention is illustrated by the drawing, which shows a General view of the installation for the processing of tailings of municipal solid waste.

A plant for processing solid domestic waste tails contains a material (tailings) pretreatment unit having a receiving device 1, a transport system 2, a ferrous metal identifier 3, a non-ferrous metal identifier 4, an actuator for metal selection 5, a pretreatment unit using a conveyor 6 is connected with final processing unit, which contains a receiving hopper 7, a zone of a high-temperature block 8, a turbine for supplying compressed air 9, a reactor 10, shutters 11, a chamber destruction 12, the control unit of the fractional composition 13, the outlet estrus 14.

The work of the installation for the processing of tailings of solid household waste is as follows.

The material (tails) enters the receiving device 1, and from there to the transport system 2, where the determinants of ferrous and non-ferrous metal connections 3 and 4, respectively, are given a command to control the actuators 5 to perform metal selection functions with the output of current signals. The transported material (tails) enters the main conveyor 6, and from there to the receiving hopper 7. From the receiving hopper 7, the material is sent to the zone of the high-temperature block 8, where it is subjected to dynamic action in an electromagnetic field. The pressurized air created by the built-in turbine 9, passing through the heat source, cools the reactor 10 and, through the louvres 11, facilitates the movement of material (tails) into the main destruction chamber 12. In the destruction chamber 12, the material is subjected to forced-dynamic action. From the chamber 12, the material enters the inter-cavity space of the block 13, where the exit of the fractional composition is controlled. From block 13, the material in processed form enters the outlet chute 14.
