Dirt and debris are trapped on the outer surface of the drum 10 and accumulate in the well 5. At the same time from the reservoir 29 to the inlet tube 20 water flows into the left chamber of the water-filled tank 16, and the ball valve 21 closes off the water flow in the right chamber of the tank 16. The water filling of the left chamber of the tank 16 to the level of the drain box 18 - capacity 16 under the influence of the weight of the water will turn to the left. This toothed segment 26, mounted on the lid of the container 16, is moved counterclockwise, acting on the toothed wheel 27 mounted on shaft 28 will rotate the wheel 27 in a clockwise direction, allowing the transmission of torque to troubleshoo system 22 engaged with the flanges 11 and 12 of the filter drum 10, which is under the influence of this will be moved to the left along the axis of the inlet pipe 1.When you move the drum 10 in the direction of the reservoir 29 to the filter valve 30 will block the inlet pipe 1, the shutter 24 is raised and opens the entrance of the discharge channel 23, and the window 8 pcisets, sequentially passes through the supply line 1 - box 8 - the internal cavity of the drum 10, then leaves him inside - out through the side of the filtering surface, washing away with this garbage, accumulated with the outer surface of the drum 10, in the well 5, and is discharged along with the debris from the well under 5 raised by the shutter 24 in the discharge channel 23. Water from niches 25 is also reset (partially) in the channel 23. Sequentially repeating the cycles of water treatment and flushing of the filter is adjusted according to the duration from the time of filling (emptying) of water-filled containers 16 to the level (level) of the Windows 18 and 19.The economic efficiency of the device for water purification is achieved through the operation of the device with the use of natural resources water energy without the cost of additional sources; automatic operation of the device; adjustable duty cycle and frequency of the regeneration of the filter.
