SU1500369A1 - Arrangement for washing and separating loose materials of different density - Google Patents

Abstract

The invention relates to the separation of bulk materials of different densities in polymeric waste processing plants. The goal is to improve the quality and speed of washing and separating polymeric wastes. For this, a washing tank 1 is positioned above the tank with a horizontal screw 5 and communicated with it. In the bath 1, vertical tape augers 3 are installed, covering the horizontal screw 5 with a mesh cylinder (SC) 7 with longitudinal slits 8 and mesh plates 9. Slot 8 divide SC 7 into lower and upper parts, and plates 9 connect lower part of SC 7 with container walls. The separation bath 10 is connected to the washing bath 1, on which devices for unloading the separation products are installed in the form of conveyors 11 and 12. Heavy particles roll down the inclined plates 9 through slots 8 in SC 7, and the lungs are forced through slots 8 by means of tape screws 3. The screw 5 transports the washed materials in a laminar flow into the separation bath 10, where the separation of materials takes place. The washed impurities that have passed through SC 7 and plates 9, together with water, are removed from the bath 1. 2 Il.

The slits 8 and the mesh plates 9. The slits 8 divide the SC 7 into lower and upper parts, and the plates 9 connect the lower part of SC 7 with the walls of the container. A separation bath 10 is connected to the washing bath 1, on which devices for unloading the separation products are installed in the form of conveyors 11 and 12. Tel-10 parts roll down on inclined plates

9 through slot 8 in SC 7, a. lungs through slots B forcefully nod with tape augers 3. Screw 5 transports washed materials in a laminar flow to a bath

10 separations, where the separation of materials takes place. The washed primeei, which passed through SC 7 and plates 9, are removed together with water from the bath 1. 2 Il.

The invention relates to the separation of bulk materials of different densities and can be used in enterprises for the processing of polymeric waste (Russia).

The purpose of the invention is to improve the quality and speed of washing and separating polymeric waste.

1 shows a structural diagram of the device; in Fig.2 a section aa in Fig.1.

The device contains a washing bath 1 with a loading tray 2, vertical tape augers 3 are installed inside the bath, receiving rotation from the drives 4, located in the tank horizontal drive screw 5 with drive 6 and mesh cylinder 7, having longitudinal slots 8 along the axis, It is placed on the lower and upper parts, to the lower parts of which are installed mesh plates 9, which connect the lower part of the mesh cylinder with the vessel walls.

The angle of inclination of the plates ot with respect to the horizontal PLANE should be equal to or greater than the angle C of the repose in a given fluid of a material with a higher density.

The device is also equipped with a separation bath 10, on which devices are installed for unloading separation products in the form of a conveyor 11 for picking light materials and a conveyor 12 for picking heavy materials. Bath 10 separation is connected with the bath 1 washing with a horizontal screw 5.

The device for washing and separating bulk materials works as follows.

In the bath 1 washing, filled with liquid, through the loading pipe 2 load materials. Turn on

Construct all screws and conveyors 3, 5, 11 and 12.

Belt augers 3, rotated by actuators 4, create a directional movement of the material into the fluid in the opposite direction. under the action of the buoyancy force of the fluid, washing it. At the same time, heavy particles roll along inclined plates 9 through slots 8 into the mesh cylinder 7 of a transmission device of the screw 5, which receives rotation from the drives 6, and the lungs through the same slots 8 are forcedly pushed when the augers 3 are rotated.

Auger 5 transports the washed materials in a laminar flow to. separation bath 10, where the separation of materials according to density occurs. The surfaced ones are captured by a partially submerged conveyor 11, and those sunk by the conveyor 12 are removed from the bath. The washed impurities that have passed through the mesh cylinder 7 and the plates 9, together with the water, are removed from the bath 1.
