The invention relates to hydrometal engineering, namely to the designs of the device for starting siphons.

The purpose of the invention is to simplify operation by ensuring self-starting.

Fig, 1 shows a siphon with non-wetted area in the outlet; FIG. 2 shows a siphon with a reservoir and a drain connection; FIG. 3, a siphon, with a reservoir separated by hygonexual diaphragms.

The siphon (Fig. 1) contains a suction and discharge connections 1 and 2, an inlet opening 3 and a trigger device made in the form of a moisture conducting element 4 and an annular non-wetted section 5 mounted in the exhaust connection A, and the moisture conducting element A has a capillary structure and is located in the pipes 1 and 2 between the inlet 3 and the non-wetted section 5,

In the second embodiment (Fig; 2), the siphon contains a suction and discharge nozzles 1 and 2, an inlet 3 and a trigger device made in the form of a moisture conducting element 4 and a tank 6 with a drain channel 7, the moisture conducting element having a capillary structure and located in the pipes 1 and 2 between the hole 3 and the tank 6, and along the perimeter of the drain channel 7 a non-wetted coating 8 is mounted, the reservoir 6 can be divided by horizontal diaphragms 9, each

of which a drain hole 10 is made, along the perimeter of which a nonwettable coating is made, and the moisture conducting element 4 is led to each of the diaphragms 9, and the diameter of the drain hole in the upper diaphragm is larger than the diameter of the other drain holes.

The device according to the first variant works as follows.

The liquid from the vessel, wetted by the moisture conducting element 4, is excreted in the form of droplets at its outer end. An annular nonwettable region 5 prevents the droplets from moving further along the inner surface of nozzles 1 and 2. After accumulating in front of it, the fluid forms an annular meniscus. As the fluid accumulates, the annular meniscus is flushed out before the nonwetting portion 5. When the weight of the liquid column exceeds the value of the product of the vertical component of the surface tension force on the perimeter of the pipe 2, the column will cross the border of the non-seam section 5, moving down. Behind the moving column of liquid, a vacuum is formed, due to which the pipe 1 is filled with liquid from the vessel and further works like a regular siphon,

With an increase in the diameter of the pipes 1 and 2 pounds of liquid accumulated before the annular non-wetted section 5, it may be insufficient to start the siphon. In this case, for

accumulation of fluid is used intermediate tank 6 (Fig. 2).

The device according to the second variant works in the following way,

The supply of liquid from the vessel to the intermediate tank 5 (Fig. 2) is initially provided with the accumulator properties of the moisture conducting element 4. The liquid accumulates in the intermediate tank 6, forming a meniscus around the upper nonwettable cover 8 of the drain channel 7. When accumulated in the intermediate tank a sufficient portion of the liquid causes a breakthrough of the meniscus and the liquid begins to flow through the drain channel 7. This forms a vacuum, which causes the siphon and the intermediate tank 6 to be filled with liquid, and eat and the outlet. Next, the system works like a regular siphon.

When the nozzle 1 is immersed in a liquid, the moisture-conducting element 4 contained therein begins to supply liquid to the diaphragms. Accumulating on the diaphragms, the fluid forms menisci around the non-wettable coatings of the holes 10. Because the area of the upper diaphragms is smaller than the others, less liquid is placed on it and its meniscus is broken first. Feeding. from the first diaphragm (paragon 1 fluid causes a breakthrough of the remaining meniscuses. Formed with the resulting jet, falling into the drain channel 7, forms a vacuum, the benefit Liquid can be accumulated on

horizontal diaphragms 9 (fig. 3), a gift to which is a siphon tube, and are located one above the other inside and the whole device is filled with a liquid intermediate reservoir 6. Allness.

The diaphragms 9 have co-located openings, along the perimeter of which non-wettable coatings are made. The dimensions of all the holes are the same, except for the hole in the uppermost diaphragm, which is larger than the others. Accordingly, the height of the upper diaphragm is smaller than the rest of the diaphragms 9.

When the nozzle 1 is immersed in a liquid, the moisture-conducting element 4 contained therein begins to supply liquid to the diaphragms. Accumulating on the diaphragms, the fluid forms menisci around the non-wettable coatings of the holes 10. Because the area of the upper diaphragms is smaller than the others, less liquid is placed on it and its meniscus is broken first. Feeding. from the first diaphragm (paralysis 1, the fluid causes a breakthrough of the remaining menisci. The jet that forms as a result of this, entering the drain channel 7, forms a vacuum, due to which the siphon tube and then the entire device is filled with fluid.
