Description

The invention relates to devices for treating water with heavy metal ions, in particular silver. It can be used in various fields of medicine, veterinary medicine and in everyday life.

Ionized water containing silver ions has pronounced bactericidal properties. Pathogenic microflora quickly dies in it, disinfection occurs. The most effective method of preparing water containing silver ions is the electrolytic method (water enrichment with silver by electrolysis).

The closest technical solution to the claimed object is an ionizer known from. Magazine: Shustov M. Ionator of water // Radio amateur. - 1995. - No. 6, pp. 19-20.

Known ionizer consists of a pulse generator, timer, power amplifier, display unit and silver electrodes. To ensure uniformity and increase the efficiency of dissolution of the electrodes it is recommended to periodically change the polarity on the electrodes. Upon reaching the optimal concentration of silver ions per unit volume (about 0.25 mg Ag / liter), it is necessary to disconnect the current in a timely manner.

This device allows you to automatically and periodically change the polarity of the voltage applied to the electrodes. The timer automatically turns off the device after a set time. For ease of use, not the time interval is set, but the volume of the activated liquid.

A disadvantage of the known device is the need for experimental installation of the distance between the electrodes and the inability to quickly adjust the current strength, the magnitude of which depends on a number of factors: the area of the electrodes, the purity (quality) of water, its temperature, interelectrode distance, etc. In addition, it is impossible to visually observe how the current strength changes. All this leads to an increase in the complexity and inconvenience of maintenance, and as a result to a lengthening of the process of enrichment of water with silver ions.

The objective of the invention is to provide visual control of the current strength, reducing the complexity of the process, improving the operating conditions of the device for ionizing water, accelerating the process of enrichment of water with silver ions.

This task is achieved due to the fact that the known device for ionizing water, containing a pulse generator, timer, power amplifier, display unit and silver electrodes, according to the invention is additionally equipped with a direct current milliammeter and a variable resistor R18, while the milliammeter is included in the display unit and is connected between LEDs and the first electrode, and the variable resistor R18 enters the power amplifier and is connected between the resistor R17 and the second electrode. In addition, the DC milliammeter is made with a 10 mA scale with a zero in the middle of the scale, and to expand the current adjustment range, the value of the resistor R17 is reduced to 100 Ohms.

The essence of the proposed solution is illustrated by the drawing, which shows a diagram of a device for ionizing water.

A device for ionizing water contains

- pulse generator 1, which includes the chip K561LE5, resistors R12-R14, capacitor C2, diode VD1;

- timer 2, which includes resistors R1-R11, a timing capacitor C1, switch SA1;

- power amplifier 3, which includes transistors VT1 ... VT4, resistor R15-R18;

- display unit 4, which includes LEDs HL1, HL2, milliammeter P1;

- silver electrodes 5 and 6.

A device for ionizing water works as follows.

A direct current is passed through the silver electrodes 5 and 6. The electrodes 5 and 6 are connected to the output of a power amplifier 3, which is necessary to obtain the maximum power of the amplified signal. In the display unit 4, LEDs HL1, HL2 are used to display the polarity on the electrodes 5 and 6. Timer 2 automatically turns off the device after a set time.

Chip K561LE5 generator 1 generates rectangular pulses, the duration of which is set by RC elements (C2, R13, R14). The K561LE5 chip is built on the basis of four logical elements: DD1.1 with inputs I, II and output III; DD1.2 with inputs IV, V and output VI; DD1.3 with inputs VII, VIII and exit IX; DD1.4. with inputs X, XI and output XII. These logic elements are built on the basis of electronic devices operating in a key mode - digital information is presented in binary form, in which signals take only two values: “0” (logical zero) and “1” (logical unit), corresponding to two key states. When the "START" button is pressed, the time-generating capacitor C1, initially charged from the power source through the chain of resistors R1 ... R11, is discharged, the logic zero value is set at the inputs of the logic elements DD1.1, DD1.2, DD1.3, DD1.4, the circuit starts generate rectangular pulses arriving at the power amplifier.

The output current of the device is regulated by a variable resistor R18. The maximum output current of the device is limited by the resistor R17 and is 6 mA. This current value corresponds to the achievement of the optimal silver concentration in 0.5 liter of water in one minute.

To adjust the current strength and set its specific value, a variable resistor R18 is used, which allows you to abandon the mechanical change in the distance between the electrodes necessary to achieve the required current value, which allows you to change the concentration of silver ions in the solution, for example, for 1 l / min current value 3 mA, and for 2 l / min - a current value of 6 mA.

A DC milliammeter P1 with a 10 mA scale with a zero in the middle of the scale allows you to control the set current value.

As the time-delay capacitor C1 charges, the voltage on it reaches such a value when the logical unit value is set at the inputs of the elements DD1.1, DD1.4, the generator and power amplifier are turned off, and no current flows through the load. The time interval is set stepwise by the switch SA1, which switches the chain of resistors R1 ... R11. The power switch in the circuit may not be available, since the current consumed by the device in the passive mode is units of microamps. Since the device is quite economical (maximum consumption current up to 3 ... 4 mA), a Krona battery can be used for power, the resource of which is enough to activate two cubic meters of water. The silver consumption in this case is 0.5 g.

For electrodes, it is desirable to use high-purity silver: for food purposes, silver is 999.9 samples, for other purposes - 875 samples. For the systematic use of water containing silver ions as drinking water, the concentration of silver ions in the solution must be reduced to 0.05 mg / l, and for the disinfection of dishes, containers, vegetables, fruits, the concentration of silver ions should be increased by an order of magnitude.

Using the proposed scheme allows you to visually control the current strength, reduce the complexity of the process, improve the operating conditions of the device for water ionization, accelerate the process of enrichment of water with silver ions.
