Description

one

The invention relates to agriculture and can be used on the suction pipe of the sprinkler units to trap suspended solids (sediment).

Known float intake devices, including a float, a pipe suction pipe of the pump and de-trapping grid.

However, the known devices do not allow the separation of suspended particles (sediments) contained in the irrigation water.

In order to remove suspended particles from the water entering the pump, the proposed float device is equipped with a hydro cyclone installed at the inlet to the suction pipe of the pump, which has a common housing with the bottom plate. In order to accumulate sediment and carry out a periodic washing of the hydrocyclone, it is equipped with a soil collector with flush valves installed under the hydrocyclone.

FIG. 1 depicts the proposed float intake, longitudinal section; in fig. 2 - the same, top view.

The device consists of cyclone receiving chamber 1, inlet nozzles 2, suction pipe tip 3, soil collector 4, transitional nozzle 5, horizontal partition 6, valve 7, air chamber 8, pneumatic valve 9, protective casing 10, check valve 11, de-slug grate 12.

The horizontal partition 6 divides the device into two parts. The upper part, being an air chamber 8, serves as a float, air is introduced into it through an air valve 9. The lower part is a cyclone chamber 1. The safety casing 10 prevents air from flowing through the inlets 2 and protects them from mechanical damage, and also serves as an orientation float in the irrigator. The ball cap 3 is a screen that destroys internal hydrodynamic eddies.

The device works as follows.

Water is sucked through the grate 12 and the inlet nozzles 2 into the receiving hydrocyclone chamber 1, where it receives an intense rotational movement, as a result of which the two-phase liquid separates in phases. Cleaned up

water through the ball cap 3 of the suction pipe and the transition pipe 5 enters the pump. The sediments concentrated in the soil collector 4 are periodically washed at the end of the working rink due to the residual pressure

in the cyclone chamber to the detriment of the pump. The flushing head is created by raising the float device to an unnecessary height.

Subject invention

1. A float intake device, including a float, a pump suction pipe, and a dehumidifier grid, characterized in that, in order to remove suspended particles from the water entering the pump, the float device is equipped with a hydro cyclone installed at the inlet of the pump suction pipe and having with float housing.

2. Device n. 1, characterized in that, in order to accumulate sediments and carry out periodic washing of the hydro cyclone, it is equipped with a soil collecting container with washing valves installed under the hydro cyclone.
