Description

The invention relates to a device for separating materials into fractions in the field of centrifugal forces, allowing the processing of materials at speeds significantly higher than the speed of rotation and thus to intensify the processing processes, and more specifically for the separation of plastic film from garbage.

Known separator for separating bulk materials into fractions in the field of centrifugal forces [1], consisting of a housing with a separation channel and a twisting device mounted on its axis, and a pipe for supplying air to a twisting device located in the lower part of the housing.

A disadvantage of the known separator is the presence of a pipe for supplying air to a screw device in the lower part of the housing, which prevents the removal of large objects from the garbage through the lower pipe and makes it impossible to separate the garbage into fractions.

The objective of the invention is the cleaning of garbage from a plastic film, possibly with its further disposal using other technologies.

The problem is solved by using a separator consisting of a cylindrical body with a separation channel, a loading hopper located in the upper part of the housing, an air supply pipe to a screw device installed in the lower part of the housing on its axis under the loading hopper, and a conical outlet pipe for the swirling air flow from the tightening device, the outlet pipe for light fractions and the outlet pipe for heavy fractions, installed respectively in the upper and lower parts of the housing, I distinguish egosya in that the air supply pipe to the swirl device is placed inside the hopper at its axis and the exit nozzle of swirling air stream from the swirl tube device aims to output light fractions.

In Fig.1 shows a separator for garbage, and in Fig.2 - section aa in Fig.1. The garbage separator consists of a cylindrical housing 1 with a separation channel 2 and also contains a loading hopper 3 located in the upper part of the housing, a screwing device 4 mounted in the lower part of the housing on its axis under the loading hopper, with an air supply pipe 5 and a conical outlet pipe swirling air flow from the swirling device 6, the outlet pipe for light fractions 7 and the outlet pipe for heavy fractions 8. Under the feed hopper 3, a truncated cone 9 is placed on the air inlet 5 echivayuschy feed garbage into the separation channel 2.

The separator for garbage works as follows. The garbage to be separated into fractions and cleaned from a plastic film is fed into the loading hopper 3 and then, with the help of a truncated cone 9, enters the separation channel 2, where it is swirled by a stream of air coming from the twisting device 4. In the separation channel, the debris is fluidized and divided into fraction, which contributes to the high speed swirling air flow. A light polyethylene film, which has a large windage, is carried away by the air flow and is carried up to the outlet pipe for light fractions. The orientation of the swirling air stream leaving the swirling device toward the outlet pipe for light fractions also contributes to this. The heavy fractions of the debris pass down and are removed from the separator through the lower outlet pipe of the heavy fractions 8.

EXAMPLE OF IMPLEMENTATION

The separator was tested on peeling the onion.

The main technical characteristics of the separator used to peel the onion from the husk:

Height - 800 mm

Diameter - 550 mm

The diameter of the twisting device is 250 mm,

Fan motor power - 3 kW,

Productivity - 15 tons per hour.
