RU2496307C1 - Sluice aeroponic column - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention is designed for growing plants in a nutrient medium without soil. The sluice aeroponic column comprises a vertical pipe with holes in the walls, irrigation nozzles, outlet and inlet pipelines of nutrient solution. In the upper part of the pipe there are apertures for fastening aerophyte sluices and air filters. Lower (narrower) part of the pipe rests on the collecting cone connected by an isthmus to a clarification tank, in which the UV lamp is located and which is connected to the tank for mineralised water. The aerophyte sluices are attached to the pipe walls in a staggered manner and represent the pipe segments with inclined cuts and clamps in a vertical plane. In the outer cut the loose environment is placed for germination and retention of plants.

EFFECT: simplifying of device design, simplifying of the device maintenance.

Description

The present alleged invention relates to the cultivation of plants without land in special devices when exposed to the root system with an aerosol nutrient solution.

Known methods of growing plants without land on vertical surfaces or devices (1, 2). Closest to this proposal is a Russian patent in which the aeroponic column contains a vertical pipe with holes in the walls, nozzles for irrigation, and the discharge and supply lines of the nutrient solution (3).

A disadvantage of the known devices is the complexity and high cost of their manufacture, increased laboriousness when planting, uneven irrigation of the roots, the high level of ZUN required for use, as well as poor plant nutrition in the early stages of germination.

The aim of the present invention is to impart to the aeroponic installation such qualities as low cost of production, ease of maintenance, ease of germination and planting of plants. This goal is achieved by the fact that in the upper part of the column there is a cone with a nozzle or nozzle system fixed on it (depending on the size of the column), there are holes in the pipe walls for fixing aerofit locks and air filters, the lower (narrower) part of the pipe rests on the collecting a cone connected to the sump and leading to the tank with mineralized water, and an ultraviolet lamp arranged so as to irradiate both the tank and the tank with mineralized water. At the same time, aerofit locks are staggered to the pipe walls and represent cylinder sections with oblique sections and detents in a vertical plane, and a loose medium is placed in the inner part of the aerofit lock.

The possibility of practical implementation.

In the drawings: FIG. 1 shows a detail of an aeroponic column. Figure 2 shows the aerofit gateway. The aeroponic column in FIG. 1 contains a column narrowed to the bottom with holes 1. The column is closed at the top with a top cone with nozzles 2 located in it and a collection cone at the bottom 3. The lower collecting cone, depending on the number of columns in the system, is connected with a short or long neck 4 with a sump 5. From the sump, water through connection 6 enters the tank with mineralized water 7. The sump and tank with mineralized water are disinfected with an ultraviolet lamp 8. Mineralized disinfected water from the tank with miner with saline water again enters the nozzles and, spraying, creates a stream of air from the upper air filters 9 to the lower 10, irrigating the roots of the plants protruding from the aerophytic locks 11 with a fog enriched with minerals.

A separate aerofit gateway is shown in FIG. 2. It consists of a casing in the form of a pipe with obliquely cut edges 12, in the inner part of which there is a bead 13, due to which a loose medium is held in the pipe 14. The aerofit gateway is held in the aeroponic column by latches 15.

The device operates as follows. Aerophytic locks 11 after planting seeds in them or sprouting them (depending on the culture) are fixed in the holes of the aeroponic column in a checkerboard pattern to increase the space of the necessary root growth and are held in it using fixatives 15. The root of the seedling sprouts through a loose medium 14 and is irrigated environment. The internal inclined section allows more efficient use of irrigation in the early stages of germination, and the external section protects against harmful organisms entering the gateway. The aeroponic column 1 narrows to the bottom, which allows more efficient irrigation of plant roots. The irrigated medium is created thanks to nozzles installed in the upper cone 2.

Depending on the number of columns, their size and place of application, water can be supplied to the nozzles of several columns to each column from an individual water pump, to several columns from one more powerful water pump and from one common tank with mineralized water 7 or from a tank where pressure created by an air compressor.

It is also recommended to connect backup sources of water pressure to the nozzle for the nozzle, such as backup water pumps, uninterruptible power supplies, backup generators, etc.

Irrigation itself occurs periodically, depending on the culture and size of the column. The frequency and duration of irrigation can be created using a relay, or a computer module.

During irrigation, a stream of water creates an air flow from the upper air filters 9 to the lower air filters 10. The internal openings of the filters are directed downward to prevent light from entering nozzles and plant roots.

Excess water flows down the lower collecting cone 3 through the isthmus 4 to the sump 5 with a transparent bottom for the UV-disinfecting water to pass through it. After filling, the water enters the drainage channel of the settled water 6 and enters the tank for mineralized water 7. The water in the tank is disinfected with an ultraviolet lamp 8. The radiation from the lamp is directed both to tank 7 and to the settler 5. It is recommended that the tank walls be coated with reflective paint, and above the sump 5, place a protective cover that will not allow ultraviolet radiation to irradiate the roots of plants.
