Abstract

The invention relates to the field of water supply and relates to water intake devices that prevent the ingress of impurities into the water supply network, for example, when collecting from reservoirs and supplying such liquids to the irrigation network. The purpose of the invention is to increase the reliability of the device by removing solid inclusions from the outer surface of the bent tubes. The intake device comprises a housing 1, a filter 6 made in the form of a perforated cylinder, in the holes of which the curved tubes 9 are rigidly fixed, the free ends of which are directed towards the movement of water flow. On the inner surface of the housing 1 are located the lugs 10, which have a streamlined shape, for example, a tapered one, which smoothly mates with the inner surface of the housing. The free ends of the bent tubes are installed coaxially in the horizontal channels of the bosses 10, while the free ends of the tubes 9 are made longer than the channels and protrude beyond their ends.

The invention relates to water supply and relates to water intake devices that prevent the ingress of impurities into the water supply network, for example, when collecting from revervarets and feeding fluids such as animal livestock to the irrigation network.

The purpose of the invention is to improve the reliability of the device by removing solid inclusions from the blasted surface and curved tubes.

FIG. 1 shows a water intake device, a longitudinal slit in FIG. 2 shows section A-A in FIG. one; FIGS. 3-4 are the node in FIG. 1 (with different positions of the bent tubes relative to the bosses).

The intake device comprises a housing 1 with an inlet 2 and an outlet 3, in which diaphragm valves 4 and 5 are placed, respectively. The housing 1 is made in the form of a truncated cone with a large base at the inlet of the flow. A filter 6 is installed inside the body. It is made in the form of a perforated cylinder placed along the axis of the body so that an annular cavity 7 is formed between them. The filter has a blind end and is made with holes 8 in which the bent tubes 9 are rigidly fixed, the free ends of which are directed in the direction of the water flow movement. On the inner surface of the housing 1 there are small bobs 10 that have a streamlined shape, for example a tapered one, which smoothly mates with the inner surface of the housing. The free ends of the bent tubes 9 are installed coaxially in the horizontal channels 11 of the bosses 10, while the free ends of the tubes 9 are made longer than the channels 11 and protrude beyond their ends. The filter 6 is connected via a telescopic connection 12 to the pipeline 13. At the outlet 3 between the walls of the housing 1 and the pipeline 13 there is an impurities accumulation chamber 14. Between the blind-end of the filter 6 and the housing 1 is installed a spring 15, placed in a protective elastic casing 16. The intake device is installed horizontally in the tank.

The intake device operates in the filtering mode and in the filter washing mode with reverse water currents. In the filtering mode, water from the reservoir enters through the inlet 2 (the diaphragm valve 4 is open) into the annular cavity 7 between the housing 1 and the filter 6, then passes through curved tubes 9 into the filter 6 and enters the pipeline 13. Due to the force of the spring 15, as well as the vacuum in the pipeline 13, the filter 6

Q enters pipeline 13, at this time the outlet 3 is blocked by the diaphragm valve 5, impurities in the water are retained at the entrance to the curved tubes 9, and large

2 impurities overlap the inlets of the bent tubes 9, and the fibrous impurities accumulate on the lugs 10 and on the walls of the bent tubes 9, Some of the impurities are inertia with the flow

The Q of water enters chamber 14, where they accumulate. When the filter clogs the fluid intake from the reservoir into the pipe 13 stops, leaving water in reverse through the pipe 13

5 enters the body 1 through curved tubes 9, partially cleaning them from impurities,

.1. Due to the fact that the fluid pressure. t in filter 6 is increased, and also 0 due to the jet forces of the jets coming out of the bent tubes 9, the filter 6, compressing the spring 15, is displaced to the inlet 2, the bent tubes 9 at the same time coming out of the horizontal channels 11 bobschzk 10, and impurities os-: melt on the latter.

At the same time, in the annular meanness 7, the pressure rises, as a result of which the diaphragm valve ,, 4 blocks the opening 2, the diaphragm valve 5 opens, Applied, located on the bob 10, into the chamber 14, reverse flow mc through hole 3.

The use of the proposed device ensures better self-cleaning of the filter element in the mode of its hydraulic and mechanical cleaning, as compared with the known limestone, which ultimately leads to an increase in the reliability of the device.
