Description

through one drainage network of ameliorative network (not shown in the drawing). The switches 3 and 10 are installed in a position in which the pressure outlet of the compressor 1 through pipes 2, 11, 13 is connected to the collector 15, and the suction inlet of the hydraulic elevator 4 through the pipes 5, 12, 14 to the collector 16. The pressure outlet water from the supply tank 6 through pipelines 9, 17 are connected to a drain collector (not shown in Fig. 1).

From compressor 1, air under pressure through pipeline 2 — switch 3 — pipeline 11 — switch 10 — pipeline 13 — collector 15 — enters the drains through one, creating an elevated pressure zone around them.

The hydraulic elevator 4 creates a discharge in the line pipeline 5 - switch 3 - pipeline 12 - switch 10 - pipeline 14 - collector 16 and then in the drains of the drainage network through one, around which a reduced pressure area is created.

Under the simultaneous influence of vacuum and air pressure, squeezing water from an inter-spacing distance to evacuated drains, the soil water over the latter enters the collector 16, pipeline 14, switch 10, pipeline 12, switch 3, pipeline 5, hydraulic elevator 4, pipeline 7, feed tank 6, air from the latter is discharged through line 8, and water through line 9 to switch 10 to line 17 enters the drainage collector.

Simultaneously with the drainage of the soil is its aeration.

Changing the position of switch 3 during operation, collectors 15 and 16 are periodically connected to the discharge outlet of compressor 1, then to the suction inlet of the hydraulic elevator, which prevents clogging of drainage networks.

For example, when humidifying with alternating water and air supply, drainage channels of the ameliorative network are connected to collectors 15 and 16 through one (or all to one of the collectors), the position of switches 3 and 10 is set depending on the operating periods — water or air supply. Thus, when supplying air, switches 3 and 10 are set to a position in which the pressure outlet of the compressor 1 is connected to both collectors 15 and 16, the hydraulic elevator 4 and the flow capacity are turned off.

From the compressor 1, the air under pressure through the pipeline 2 - switch 3 - pipelines 11 and 12 - switch 10 - pipelines 13 and 14 enters the collectors 15 and 16 and further into the drains.

During the water supply period, the switches 3 and 10 are set to the position at which the suction inlet of the hydraulic elevator 4

connects to the drainage collector and the discharge outlet of the supply tank 6 to the collectors 15 and 16. Compressor I is shut off during this period.

The hydraulic elevator 4 - creates discharge in the pipeline 5 - switch 3 - pipeline 12 - switch 10 - pipeline 17. Under the influence of vacuum, water from the collector flows through the pipeline 17 - switch 10 - pipeline 12 - switch 3 - pipeline 5 - hydraulic elevator 4 - pipe 7 into the supply tank 6. From the latter, air is discharged through line 8, and water through the line pipe 9 - switch 10 - pipelines 13 and 14 are fed under pressure through manifolds 15 and 16 into drains of the reclamation network.

Periodically, during operation, the positions of switches 3 and 10 produce an accelerated soil moistening with simultaneous aeration.

For example, when moistening with a periodic change in the pressure gradient to the collectors 15 and 16 is connected through one drain of the drainage network (or all to one of the collectors), the switches 3 and 10 are set depending on the period of the pressure water supply or the evacuation.

Thus, during the period of vacuuming, switches 3 and 10 are set to the position in which the suction inlet of the hydraulic elevator is connected to the collectors 15 and 16, and the pressure outlet of the water flow rate 6 to the collector of the drainage flow. Compressor 1 is turned off during this period.

During the period of the pressure water supply, the switches 3 and 10 are set to the position in which the suction inlet of the hydraulic elevator 4 is connected to the drainage collector and the pressure outlet water of the supply tank 6 to the collectors 15 and 16. The compressor 1 is turned off during this period of operation.

Dumping is done by choosing the mode of vibrations in such a way that the amount of water supplied to the drains in the first half period is equal to the amount of water pumped out in the second half period.

The proposed installation also allows you to separately carry out each of the reclamation processes (removal, drainage, aeration).

The installation can be connected via pipelines 13 and 14 directly to the collectors of reclamation systems.

The combination of various ameliorative processes and methods of their intensification expands the technological capabilities of the plant and allows to obtain a significant economic effect by reducing the drainage time, moistening, water consumption for moistening, and improving the plant aeration of plants, which ultimately will lead to higher yields of agricultural crops. .

In the proposed facility, it is possible to use equipment that is sourly manufactured by industry, which simplifies its manufacture and operation.

The installation can be made both stationary and mobile by mounting the equipment on the chassis.
