SK148992A3 - Dose unit of liquid on float - Google Patents

Description

The invention relates to a device for the controlled dosing of disinfectant solutions, in particular for the treatment of drinking and process water, possibly for other controlled treatment of liquids, or for the controlled collection of liquids for laboratory and other purposes.

BACKGROUND OF THE INVENTION

The hitherto used devices for the treatment of drinking water with disinfectant solutions are based on the dosing of the disinfectant solution present in the reservoir by its dripping through a capillary. The disadvantage of these devices is that they do not allow the dosing of the disinfectant solution, depending on the amount of science being treated, resulting in an overdose or underdosing of the disinfectant solution.

There are known devices operating on the principle of using pressurized water supplied to a set of vessels interconnected by capillaries. The disadvantage of these devices is their complexity and consequent high demands on their maintenance.

Drinking water treatment for public water mains of larger cities is provided by chlorates for chlorine gas. Chlorine gas treatment plants operate on the principle of adjusting the amount of disinfectant gas to be supplied regardless of the amount of drinking water to be treated. The disadvantage of these devices, in addition to not allowing accurate dosing of the chlorine gas in dependence on the amount of water to be treated, is that they are difficult to temper the spaces in which they are located and that they are very expensive.

SUMMARY OF THE INVENTION

These drawbacks are overcome by a float dosing unit consisting of a dosing unit body, an electromagnetic coil, a working piston and a float.

The principle of the device according to the invention consists in the fact that the whole device is placed on the surface of disinfectant or other liquid, which by means of a working piston controlled by an electromagnetic coil on the basis of an electric pulse. and tubes to the liquid to be treated, or a laboratory vessel.

The device according to the invention operates in an automatic mode, wherein the dosing or withdrawing intervals of the liquid are adjusted depending on the flow rate of the treated or withdrawn liquid using a flowmeter and an electronic or timing device controlling the operation of the electromagnetic coil and thereby movement of the working piston.

The device according to the invention is explained in more detail by means of the drawings, in which Fig. 1 shows schematically a cross-sectional embodiment of the invention, Fig. 2 shows the device in key mode and Fig. 3 shows the device in working mode.

An embodiment of the invention

The float dosing unit according to FIG. 1 consists of the dosing unit body 1, the electromagnetic coil 2, the float 3 and the working piston 4.

The body of the dosing unit 1 is constructed in such a way that it has a working space 5 ^{and a} bypass space 6, which are separated from each other by an inner wall S, provided with a bypass opening:

mi 2_. An electromagnetic coil 2 is mounted over the upper horizontal wall of the dosing unit. The outer wall 9 of the passage space 6 is provided with openings 10 for receiving a pipe 11 which is flexible.

2 to the working space ³ and equipped with a plate 12 of the working piston 4, the guide bar 13 passes through the Central American Electric solenoid 2 and the ending of the detent 14. The internal wall 13 of the body of the dosage unit £ 12 and the plate of the working piston 4 is formed overflow slot 15 '

The body of the dosing unit 1 is mounted in a float 2 resting on the level of liquid 10 contained in the container 17.

The float dosing unit made according to FIG. 1 is placed in a container 17 filled with disinfectant solution or other liquid 16.

In the key mode of the device, the working piston 4 is by its own weight and under the action of the retainer 14 located at the lower edge of the working space 5. »Through the discharging slot 15, the disinfectant solution 16 passes over the plate 12 of the working piston 4 into the working space.

The operating mode is reached by an electrical pulse, determined by the amount of liquid to be treated, by the flow meter data and by an electronic or timing device which controls the electromagnetic coil. The action of the electromagnetic coil 2 causes the working piston 4 to be ejected, whose plate 12, in this stroke movement, expels the liquid 16 located above the upper side of the plate 12, through the through holes 7 into the through space 6 and further through the outlet 10 and .

When the electrical pulse is terminated, the working piston is returned to the key position with a proper weight and the device is ready to repeat the process.

The float dosing unit made according to FIG. 1 can also be used for taking laboratory or other samples of waste water or other liquid substances. For this purpose, the device shall be placed on the surface of the liquid to be sampled. By keeping the same oostuo, the removed liquid is passed through the orifice holes 7 into the bypass space 6 and further through the outlet 10 and the pipe 11 into the prepared laboratory vessel.

Method of industrial applicability of the invention

The invention is particularly useful for the controlled treatment of drinking water with disinfectant solutions for public water supply, wells and other sources of drinking or service water. It can also be used wherever treatment of other liquids is required, or controlled sampling of solutions, effluents and other liquids for laboratory and other purposes.
