The termination of the filtration process helps to increase the level of the initial liquid, leading to the operation of an additional siphon 17 of accelerated dewatering with removal of sediment into the tank 14. When the level of the initial liquid decreases to the level of the hole 19, a hydraulic flushing device is put into operation. element 2, J tab., 2 Il.

The invention relates to filtering installations and can be used to clean natural and wastewater from suspended solids.

The aim of the invention is to improve the efficiency of water purification by automating the washing process.

FIG. 1 shows a device, a general view in section; FIG. 2 - e, the plan. ten

The device includes a housing 1 installed in it. concentric with filter element 2, supply pipelines for initial 3 and discharge of purified 4 water, main siphon 5, ascending 5 which branch with non-return valve 6 is arranged in filter element 2 along its axis, and descending with non-return valve 7 in tank 8 of filtered water devices 9 for washing 20 ki with nozzles 10 connecting them with the ascending branch of the siphon 5, charging tank 11 equipped with a float valve 12 and air tube 13, and a reserve 14 communicating with the housing 1 through nozzles 15 with non-return valves 16, obstacles The siphon 17 connects the lower part of the housing 1 to the reserve tank and is made with a hole 19 on the upstream branch to discharge and stop operation, and the siphon 18 is provided with a check valve 35, 35. connects the upstream

the main siphon branch 5 with a filtered water tank 8 in the upper part with a charging capacity I. The filter element 2 in the upper part is equipped with a water partition 21. A sludge 21 is removed from the tank 14 through the pipeline 22.

The device works as follows.

The initial waste water through conduit 3 enters the cylindrical filtering element 2, which, when filled with filtered water, charges the main siphon 5. During the charging of the main siphon, the check valve 20 prevents water from flowing through the siphon 18 into the container B of the filtered water. At this moment, the siphon 18 and the charging tank 11 are filled, the float valve 12 at the same time occupies the upper position, and the filtered water through the siphon 5 enters the tank 8, from which the pipeline 4 flows to the consumer.

In the process of filtering, the pores of the mesh of element 2 are clogged with particles of suspended substances; therefore, losses in resistance to filtration increase and the level of the initial fluid in housing 1 falls. At some point, the water reaches the top point and charges siphon 17,

During operation, the siphon 17 ensures a rapid decrease in the level of the original liquid to the level of the hole 19 due to

removing the sediment and water from the housing 1 to the reserve tank 14. At the time the siphon 17 is put into operation, the supply of source water through the pipeline 3 stops and the main siphon 5 is discontinued from the operation. At the moment of supporting the ascending branch of the siphon 5, the water from the tank 11 goes down and charges an additional siphon 18.

During the period of operation of the siphon 18, the float valve 12, lowering to the bottom of the tank 11, blocks the siphon from air entering through the tube 13. A 06 valve 6, located at the end of the upstream branch of the siphon 5, closes and the filtered liquid supplied by the siphon 18 from the tank 8, flows through the nozzles 10 to the flushing devices 9, driving them to the rotation according to the Segnerra principle and washing the filter element

From the beginning of the operation of the siphon 18, the valve on the pipeline 22 opens and the sediment deposited in the reserve tank and transferred from the housing 1 is removed from the system. Thereafter, the valve on the pipe 22 closes and the liquid level in the reserve tank 14 rises. Upon reaching the liquid level above the nozzle 15, the check valves 16 are activated, and the liquid from the reserve tank through the nozzles 15 enters the body 1 for filtration.

Suspended substances removed from the mesh surface of the filtering element 2, precipitate, which is perirdically transported via siphon 17 (as the initial fluid level increases) from the conical part of the body to reservoir 14, and then removed via conduit 22.

The performance of the pre-burned device in comparison with lime

are shown in the table.

As can be seen from the presented data, the efficiency of the proposed device for all major

kazatel exceeds the work of the famous filter
