SELF-CLEANING FILTER FOR CLEANING OF LIQUID FROM GARBAGE Russian patent published in 2020 - IPC B01D35/02 C02F1/00 C02F103/02 B01D39/20 

FIELD: treatment of water, industrial and household waste water.

SUBSTANCE: invention relates to liquid purification means and can be used, in particular, for cleaning water from garbage in large water lines, for example, in pressure pipelines of circulating water of cooling systems of condensers of steam turbines. Self-cleaning filter for cleaning of liquid from garbage, having fixed in cut on pressure section of pipeline fixed housing and system of automatic control of process of self-cleaning filter contains: fixed frame inside housing with fixed filter surface; located on the side of the inlet end along the liquid flow of the frame end, a rotary dustbin chamber, which is installed on the sliding bearings and is connected to the garbage discharge line; electric motor with reduction gear 40 of said rotary garbage chamber comprises drive and driven elements interacting with each other. Driven element is a driven shaft, one end of which is rigidly fixed in the hole of the sliding bearing, and at the other end a worm wheel is installed. At that, the driven element is installed on motor shaft 39, which is connected to the garbage chamber, to ensure its rotation. Drive element is composite driving shaft with worm installed on it, which interacts with worm wheel, At that, drive element shaft is fitted on plain bearing at support point in wall of said fixed case. At that, all sliding bearings are coated with Stellite 1 hardening coating. Due to the fact that cylindrical shaft of rotary dust collecting chamber and drive shaft are installed on sliding bearings on which there is applied a hardening coating from Stellite 1, higher wear resistance of sliding bearings of self-cleaning filter.

EFFECT: due to the rotary dustbin chamber implementation, and the fixed filtering surface, the power consumption and load on the self-cleaning filter sliding bearings is reduced.
