The body 2 of the cap 1 is directed onto the water, the direction of movement changes from top to bottom, enters the body 2 of the cap 1 and then into the filter charge 24 for joint water-conducting washing.

Применение предлагаемого дренажа обеспечивает равномерное распределение во- довоздушной смеси между колпачками. Это повыщает эффективность промывки за счет использовани кинетической энергии движеэкономии электроэнергии. Равномерное распределение водовоздушной смеси позвол ет также снизить количество колпачков до 4 щт. на 1 м.Упрощение эксплуатации заключаетс в том, то струенаправл ющее сопло 11, установленное аксиально в смесительной камере 10. вл етс сменным, поэтому установка сопла с измененными конструктивными паприкрепленный к крыщке 4.The application of the proposed drainage ensures an even distribution of the air-air mixture between the caps. This increases washing efficiency by using kinetic energy to drive energy savings. Even distribution of the air / water mixture also reduces the number of caps to 4 cm. 1 m. Simplification of operation consists in the fact that the diverting nozzle 11 installed axially in the mixing chamber 10. is interchangeable, therefore the installation of the nozzle with modified structural elements attached to the lid 4.

К нижней части ствола 7 прикреплен хвостовик 9, выполненный в виде диффузора и снабженный смесительной камерой 10 с аксиально расположенным струенаправл ю- 20 щим соплом 11, имеющим в нижнем основании отвверстие 12, в верхнем - отверстие 13. Под нижним основанием струенаправл юще- го сопла 11, размещена сменна накидна гайка 14 с отверстием 15.A shank 9, made in the form of a diffuser and equipped with a mixing chamber 10 with an axially located jetting nozzle 11 having a hole 12 in the lower base, is attached to the lower part of the barrel 7, and an aperture 13 is located in the upper base. Under the lower base of the diverting nozzle 11, a removable cap nut 14 with a hole 15 is placed.

Хвостовик 9 со смесительной камерой и воздушной труб- 30 кой 16 размещен в поддренажном пространстве фильтра 19.To the side wall of the mixing chamber 10 25 there is no water in the barrel for air supply without an air tube 16 attached, which uses air blowers, which helps to be connected with cap nuts 17 to the pipeline 18. The latter is connected to the atmosphere by a piping system with stop valves (not shown) . The tail 9 with the mixing chamber and the air tube 30 is placed in the under-drain space of the filter 19.

The air / water flushing device is as follows.

The flushing water under pressure enters the podnodrenazhnoe space. Then, a pivoting nozzle 11, a chamber 10, a shank 9, passes along the barrel 7 and rushes into the cap 1.

In the mixing chamber 10, due to the high flow rate, a vacuum is created where air from the conduit 18 flows through the air tube 16. The air-breathing cap 1 formed in the chamber 10 passes the air through the slots 3 and 5 into the filter charge.

on the water, changing the direction of movement from top to bottom, enters the body 2 of the cap 1 and then into the filter charge 24 for joint water-flushing.

The application of the proposed drainage ensures an even distribution of the air-air mixture between the caps. This increases the flushing efficiency by using the kinetic energy of moving water in the barrel to supply air without using blowers, which contributes to

energy savings. Even distribution of the air / water mixture also reduces the number of caps to 4 cm. 1 m. Simplification of operation consists in the fact that the jetting nozzle 11 installed axially in the mixing chamber 10. is replaceable, therefore the installation of a nozzle with modified structural water drops in the barrel for air supply without using blowers, which contributes to

Using smart meters (taper angle and hole diameters in the upper and lower bases) allows changing the parameters of the drainage operation without changing its design. Zame
