The disadvantages of the analogue are the limited use of a device designed to improve the functioning of reactors for the treatment of natural and wastewater, but not for direct use in devices for cleaning hydroponic coatings, a relatively low throughput, the need for periodic cleaning and replacement of a nylon fabric filter.

The closest in technical essence and the achieved result is a machine for washing vegetables, root crops and fruits, including a drive, a shower device, rolls located on two concentric arcs of circles and rotating around their axes at different speeds, with an elastic band of comb shape, characterized in that it is equipped with arcuate clips in which the rolls are mounted rotatably in one direction, and the comb-shaped ribbon is wound on adjacent rollers at different angles of the line, with the crests of the tape on each roll installed opposite the depressions between the crests of the tape of adjacent rolls [Patent for the invention of the Russian Federation No. 2284137 IPC (2006.01): A23N 12/02, 2005].

The disadvantages of the prototype are the structural and technological complexity of the machine, the need to use an electric motor and a large number of moving parts difficult to manufacture.

The objective of the utility model is to develop a device of a more advanced, simplified design, with a decrease in the number of moving parts, with a combination of the washing and disinfection of expanded clay contaminated with biofilms, as well as the primary treatment of water from large suspended particles: sand, soil and clay.

The stated technical problem is solved by using a rectangular housing with a trapezoidal top and bottom, connected to a pipeline to remove compacted sediment, plastic pipes are vertically located between the gratings, while perforated polymer tubes for supplying air and water are alternately installed between the grating and vertical pipes Anolyte solution, while these pipes are perforated only from the side of contact with the upper grill, and the perforation of the pipe for supplying an aqueous solution Anolyte ora is made at an angle of 40-60 ° in the direction of expanded clay granules movement, and nozzles can be installed to increase the pressure and accuracy of the jet direction, and emergency and discharge drain pipelines are installed on the side wall of the housing.

It is advisable to use gratings with square cells of 5-10 mm in size, since they are publicly available, and the cell size will allow large particles of sand, soil, clay to pass through, not allowing expanded clay to get stuck and fall through. To increase the service life, vertical pipes can be plastic, it is also possible to use other diameters, but a diameter of 100 mm is a publicly available standard size, convenient for preventive maintenance both manually and mechanically. The optimum pipe height of 75 mm was calculated according to SP 32.13330.2012 and will allow particles to be deposited with a diameter of up to 10 ^-4 m during the washing process, if necessary, the deposition of larger / smaller particles of the pipe can be shortened / elongated.

The technical result is the combination of the washing process, disinfection of claydite contaminated with biofilms and the primary treatment of water from large suspended particles: sand, soil and clay and, as a result, an increase in the throughput of the device due to fewer stops for maintenance, there is no need for periodic washing of clogged filters, minimum number of moving parts.

The hydroponic coating cleaning device is designed to combine washing and disinfecting claydite contaminated with biofilms, primary water purification in one device, simplifying the washing design by using the pressure of an anolyte aqueous solution to promote and clean expanded clay granules instead of electric drives.

The technical result is provided:

through the use of a rectangular case with a trapezoidal top and bottom, for entry, output and collection of large settling particles;

due to the use of perforated polymer tubes to supply an anolyte aqueous solution with perforation at an angle of 40-60 ° in the direction of movement of expanded clay granules providing washing, disinfection and movement;

through the use of vertical pipes that prevent mixing and agitation of the settling particles.

due to the use of an anolyte aqueous solution, disinfection of not only expanded clay granules, but also all parts of the apparatus is ensured, thereby there is no secondary infection of expanded clay granules at the washing stage.

The utility model is illustrated by drawings.

A device for cleaning a hydroponic coating includes a rectangular housing 1 with a trapezoidal top and a bottom connected to a pipe 2 to remove compacted sediment, inside the housing between grids 3, 4 with square cells 5-10 mm in size, plastic pipes 5 with a diameter of 100 mm are vertically located and an optimal height of 75 mm, while between the grill 3 and the vertical pipes 5, alternating, perforated polymer tubes for supplying air 6 and for supplying an aqueous solution of Anolyte 7 are installed, while the pipes 6 and 7 are perforated They are only from the side of contact with the grill 3 (Fig. 1, 2), and the perforation of the pipe 7 is made at an angle of 40-60 ° in the direction of movement of expanded clay granules (Fig. 3, 4), and to increase the pressure and accuracy of the direction of the jet can be nozzles are installed (Fig. 4), and an emergency 8 drain, discharge 9 drain pipes are installed on the side wall of the housing.

The device operates as follows.

Expanded clay granules intended for cleaning are fed (manually or mechanically) through the device entrance (shown by an arrow) into its internal cavity of the housing 1 to the grate 3, while the housing 1 is filled with anolyte aqueous solution to the emergency drain level 8. After immersion in an aqueous solution the granules begin to rotate and move towards the exit (shown by the arrow), provided by the supply of an anolyte aqueous solution through a perforated pipe 7 with perforation at an angle of 40-60 ° in the direction of the expanded clay granules, while the jets of the Anoli aqueous solution This knocks adhering particles from the surface of the fruit. Together with the supply of Anolyte aqueous solutions, air is supplied through line 6, which reduces the density of water, as a result of which the aqueous medium saturated with air has a lower density, as a result of which small heavy particles (sand, soil, clay) lower down faster, passing through the grate 3 , vertical pipes 5, grate 4, settle on the conical bottom of the housing 1 and are later discharged through pipe 2. Vertical pipes 5 are a barrier to the mixing and agitation of settling particles, as a result of which their speed increases sedans. As water flows through the perforated polymer tubes 7, the excess, waste water solution is discharged through the drain pipe 9. In an emergency, the water solution is discharged through the emergency pipe 8. After the movement is completed and the exit (shown by the arrow) is reached, expanded clay granules (manually or mechanically) are removed from devices. During operation, particles of sand, soil, clay can contaminate the grids 3, 4 and vertical pipes 5, to eliminate this, after the cleaning process is completed, it is necessary to drain the water through the drain pipe 9, remove the grids 3, 4 and vertical pipes 5, rinse them in running water and install back into the device case, the device is ready for further operation.
