Description

The invention relates to the field of filtration and can be used in the automotive, chemical and other industries for cleaning liquids from mechanical impurities.

The aim of the invention is to increase the efficiency of filtration by reducing the consumption of filter material and increase the duration of the work cycle.

filter for cleaning the fluid from mechanical impurities ^ empty * from reservoir 1. separately ^)., perforated horizontal interturbation 2 into the upper chamber 3 of the initial fluid and lower filtrate chamber 4. On the perforated partition 2 there is a rolled filtering material 5, which is, for example, a paper web wound on a reel 6. In the upper chamber 3 there is a scraper conveyor 7, the scrapers of the lower branch of which are in contact with the filter material 5, and under its upper branch there is an impermeable for large particles of mechanical impurities additional filter partition 8, in contact with the scrapers of the upper branch of the conveyor 7.

The pipe 9 for supplying the source fluid is located above the upper branch of the conveyor at the location of the partition 8. The pipe 10 for discharging the filtrate is connected to the suction port of the pump 11. Above the upper chamber 3 of the source fluid there is a tank 12 connected via a pipeline 33 fitted with a valve 14 with the lower chamber 4 filtrate and through trubonro ·

water 15 having a valve 16, with a pressure line 17 of the purified liquid.

The filter works as follows.

Contaminated liquid is fed into the upper chamber 3 of the filter through the pipe 9. The largest particles from mechanical impurities settle on the partition 8 between the scrapers of the upper branch of the conveyor 7. The liquid is filtered through the filtering material 5 and passes through a perforated partition 2 into the filtrate chamber 4, from which through the nozzle 10 is pumped out by the pump 11. A part of the purified liquid through the pipeline 15 is taken from the pressure line 17 and enters the tank 12 to fill it, after which the valve 16 on the pipeline 15 is closed. When a predetermined value of filtration resistance is reached, the valve 14 opens on the pipeline 13, in the lower chamber 4 a backwater of the liquid is created, facilitating the movement of the filtering material. The scraper conveyor 7 is turned on, which with its lower branch moves the filter material 5, removes the contaminated area along with the sludge and feeds the clean section of filter material to the perforated partition 2 from the coil 6.

When the upper branch of the conveyor 7 moves along the partition 8, large particles of mechanical impurities settled on it are grabbed by its scrapers and are distributed evenly in a clean area of the filtering material, which prevents the penetration of fine particles of mechanical impurities into the pores of the material.

After changing the filter material, the filtration cycle is repeated.
