Implementation of the utility model.

The device for automatic sanitation of tanks of installations for bottling drinking water contains a filter 1 (see figure 1) and a pump 2.

The device for automatic sanitation of tanks of installations for bottling drinking water also contains a water intake line and a water discharge line. The water intake line is formed by the pump 2 and the intake tube 4. One end of the intake tube 4 is connected to the inlet of the pump 2, and the other end of the intake tube 4 is freely placed in the drinking water bottling tank. The water discharge line is formed by a pump 2, an intermediate tube 3 and a filter 1, with one end of the intermediate tube 3 connected to the outlet of the pump 2, and the other to the fitting 11 of the filter 1.

Pump 2 is connected to timer 7 and pulse width modulator 8.

Pump 2, timer 7, pulse-width modulator 8 are mounted in a separate housing 5. Pump 2, timer 7 and pulse-width modulator 8 are powered from power supply 6.

In particular, the filter 1 may include a filter housing 9 (see figure 3) with a cover 10 and fitting 11, a filter element 12. The filter element 12 is placed in the internal cavity of the filter housing 9. The filter element 12 of the filter 1 contains non-woven polypropylene 13 , activated coconut carbon with silver 14, fibrous cation exchanger 15, hydrophilic membrane 16. Non-woven polypropylene 13, fibrous cation exchanger 15, hydrophilic membrane 16 are made in the form of discs and alternately laid in layers from top to bottom in the inner cavity of the filter housing 9. Activated coconut carbon with silver 14 made in the form of granules and filled into the filter housing 9 between non-woven polypropylene 13 and fibrous cation exchanger 15.

In particular, the fibrous cation exchanger 15 may be in the form of a non-woven or staple fiber.

Device for automatic sanitation of tanks installations for bottling drinking water operates as follows.

The power supply 6 is connected to the network, the time interval is set by the timer 7 and with what frequency the pump 2 will be turned on for automatic sanitation of the tanks.

By changing the pulse-width modulator 8 the current strength in the electrical circuit, the required speed of pumping water of the sanitized tank is set.

After turning on the power supply 6, the electrical signal converted by the pulse-width modulator 8 is supplied to the pump 2, the rotor of which, rotating at a given frequency, through the intake tube 4 provides water intake from the installation tank and sends it with the necessary pressure through the intermediate tube 3 to the filter 1. Cleaned in the filter 1, water exits through the holes located in the bottom of the filter housing 9 into the installation tank.

When installing the filter 1 outside the tank of the installation for bottling drinking water (see figure 2), the filter housing 9 is sealed, and on the bottom of the filter housing 9, an outlet fitting 17 with an additional tube 18 is installed, the free end of which is placed in the tank of the installation for bottling drinking water. In this variant, the water purified in the filter 1 exits through an additional tube 18 into the installation tank.

The use of filter 1 provides cleaning of the sanitized tank of the installation and water with the required quality.

The use of pump 2 ensures the intake of water from the sanitized tank and its transportation to filter 1.

The presence of a separate case 5 with a power supply unit 6, a timer 7 and a pulse-width modulator 8 placed in it, allows, depending on the design features of the installation for bottling drinking water, to install it both in the case and outside the case of the sanitized installation.

The presence of a timer 7 in the device allows the operator to set the time of switching on the pump 2 and the duration of its operation, thereby ensuring automatic sanitation of the installation tank without direct human participation.

The use of a pulse-width modulator, electrically connected to pump 2, makes it possible, depending on the contamination of the tank, to set the required pressure and provide the necessary flow rate from the purified water discharge line, which, in turn, forms turbulent flows along the walls of the tank being sanitized, and additionally contributes to the cleaning of the tank without direct dismantling of the installation tank.

The use of non-woven polypropylene 13 makes it possible to remove particles larger than 5 microns from the sanitized tank.

The use of activated coconut carbon with silver 14 allows you to suppress the reproduction and development of bacteria in the tank, remove harmful odors and gases, chlorine, and improve the organoleptic characteristics of water.

The use of fibrous cation exchanger 15 in the form of a non-woven or staple fiber makes it possible to remove ions of iron and heavy metals, such as lead, cadmium, manganese, mercury, copper, nickel, etc., from drinking water, provided that the natural ionic composition of water is preserved.

The use of a hydrophilic membrane 16 makes it possible to clarify the water and remove bacteria from it.

The use of an automatic tank sanitization device for drinking water bottling plants improves the quality of tank cleaning without direct disassembly of the plant.
