SU1482568A1 - Installation for introducing liquid fertilizers with irrigating water - Google Patents

Abstract

The invention relates to agricultural equipment and is intended for the application of liquid fertilizer with irrigation water. The aim of the invention is to improve the reliability of the ejector device and the expansion of the range of applications, as well as improving the accuracy of controlling the flow of liquid fertilizers. In the tank 1, the upper part with water is divided by a partition 5 with liquid fertilizers located under the partition. Due to the fact that the average bulk density of the septum material is less than the density of liquid fertilizers, but greater than the density of water, the partition 5 floats at their boundary and thereby separates the liquid media during the consumption of liquid fertilizers, preventing them from mixing. 1 hp f-ly, 1 ill.

Description

The invention relates to agricultural equipment and is intended for the application of liquid fertilizers and other chemicals with irrigation water of sprinkler machines.

The purpose of the invention is to increase the reliability of the device, expanding the range of application, as well as improving the accuracy of controlling the flow rate of liquid fertilizers.

The drawing shows the scheme of the proposed installation.

The installation consists of a tank 1, the upper part of which is hydraulically connected to the pressure pipe 2 by the inlet pipe 3, and the lower part of the tank, respectively, by the pipe 4. Inside the tank there is a flat partition 5 freely floating at the border of water and liquid fertilizers, constantly sharing them. The inlet 3 and the pipe 4 are equipped with valves 6 and 7. The container has a level gauge 8 of transparent material. Inside the level gauge 8 there is a partition 9 floating at the water-liquid fertilizer interface. The average density of the volume occupied by the partitions 5 and 9 is lower than the density of liquid fertilizers and higher than the density of water. Partitions 5 and 9 can be made of thin-sheet material or hollow. At the bottom of the tank 1, a pipe 10 is installed, and at the end of the pipe 4 an ejector input 11 is installed.

After filling the tank 1 through the pipe 10 with liquid fertilizer, the valve 6 at the inlet pipe 3 and the valve 7 at the pipe 4 are opened successively. speeds along the flow axis and at the walls of the pressure pipe 2 of the fertilizer are fed through an ejector post 11 into the pressure pipe (sprinkler) 2, where they are mixed with

Water and then fall into the rain-nozzles (not shown).

The flow rate is controlled visually on the level gauge 8 with a partition 9. At the end of the Watering, the valves 6 and 7 are closed.

The presence of a gap between the partition 5 and the walls of the tank 1 size 1-2 mm does not lead to a noticeable mixing of water and liquid fertilizer for several days, because there is no mixing jets at the interface.
