Description

The invention relates to a device for the purification of tap, artesian, well and other conditionally drinking water.

A device for water purification, including a tank for water and technical means for cooling and heating (Lyubarsky V.M. Precipitation of natural waters and methods for their treatment. M: Stroyizdat, 1980, p. 98-99).

The disadvantage of such devices is the insufficiently high-quality water purification associated with the technological complexity of the cooling and heating process.

Closest to the proposed device is a water purifier based on the production of thawed drinking water, which includes a zone of freezing water, a zone of displacement of impurities from the ice front and the concentration of these impurities in the form of a brine, a zone of transition of water from solid to liquid, with all zones located in series one longitudinal vessel, in the freezing zone an annular freezer is installed, behind which a drive device for longitudinal movement of the frozen water rod is mounted, and in the displacement zone I impurities placed in the center of the frozen rod uncoupling device, behind which there is an annular heating element, and for the output of impurities in the form of brine and melt water there are separate nozzles located in the lower part of the longitudinal vessel (RF Patent No. 2312817 from 12/20/2007, С02F 1 / 22).

A disadvantage of the known water purifier is low productivity due to structural imperfections in the design of the uncoupling device, which does not allow to increase productivity and obtain a high degree of purity of water.

The technical problem to which the invention is directed is to increase the productivity and degree of purity of water.

This goal is achieved by the fact that in the proposed technical solution, including a zone of freezing water, a zone of displacement of impurities from the ice front and the concentration of impurities in the form of a brine, a zone of transition of water from solid to liquid, all zones are located sequentially in one longitudinal vessel, A freezing ring is installed in the freezing zone, behind which a drive device for the longitudinal movement of the frozen water rod is mounted, and in the center of the impurity displacement, it is placed in the center of the frozen reaping uncoupling device, behind which there is an annular heating element, and for removing impurities in the form of brine and melt water there are separate nozzles located in the lower part of the longitudinal vessel, according to the invention, an injector is placed inside the uncoupling device for supplying hot air to the impurity displacement zone under pressure . In addition, the nozzle is made in the form of a metal tube into which hot air is supplied through a hose through a blower.

Placing a nozzle inside the uncoupling device to supply hot air under pressure to the displacement zone of impurities, made in the form of a metal tube into which hot air is supplied through a hose through a blower, which makes it possible to ensure the movement of a frozen water rod over the uncoupling device and to efficiently remove impurities due to the temperature treatment of the frozen water rod, which increases the productivity and quality of cleaning.

The invention is illustrated in the drawing.

It shows the operation of the water purifier with the main structural elements of the device.

The water purifier contains a longitudinal vessel 1, in the water freezing zone of which an annular freezer 2 of known design and operating principle is installed, a drive device for longitudinal movement of the frozen rod 3 is mounted behind it, made in the form of rollers 4 with gear surfaces engaged with the frozen rod 3 through slots 5 in a longitudinal vessel 1, which are located around the perimeter of the longitudinal vessel 1. For the rotation of the rollers 4, a drive of known designs is used. In the displacement zone of impurities, a disconnecting device in the form of a pipe 6 is placed in the center of the frozen rod 3, which has a cutting part 7 at the inlet and an expanding profile forming an outlet pipe 8 for removing impurities in the form of a brine into the sewer 9. Inside the disconnecting device - pipe 6 there is a nozzle for supplying hot air under pressure to the displacement zone of impurities, which is made in the form of a metal tube 10 into which hot air is supplied through a hose through a blower in a known manner.

An annular heating element 11 is located in the zone of transition of water from a solid state to a liquid one. To melt water, there is a pipe 12, opposite which there are containers 13 for collecting the finished product.

To supply water to the water purifier using well-known device designs, with regulators 14.

The principle of operation of the device is the continuous production of melt water according to a strictly defined time and temperature scheme repeating the process of formation of melt water in nature.

Water, for example, tap water, is supplied to a vessel 1, where it is frozen at a slow pace through an annular freezer 2, at which the gaps between ice crystals are filled with new crystals, and the solution of salts and other harmful substances in water (i.e. brine) has time to flow out of inter-crystal gaps and focus in the Central part of the frozen rod 3. In this case, the frozen rod 3 through the rollers 4 is continuously pushed onto the cutting part 7 of the pipe 6, due to which there is a mechanical separation impurities in the form of brine (such as compacted snow) from pure ice. Through the nozzle - a metal tube 10 through a hose (not shown) connected with a blower serves hot air at temperatures up to 160 ° C under a pressure of 0.1-0.4 atm. In this regard, the frozen rod 3 melts not only due to the annular heating element 11 from the outside, but also by blowing hot air from the inside.

Separated impurities at the outlet pipe 8 enter the sewer 9. After releasing the frozen rod 3 from the central part, it is pushed onto the annular heating element 11, which allows defrosting the ice with the formation of active drinking water having an ordered structure similar to the structure of melt water. Through the pipe 12, melt water enters the tank 13. To supply the required amount of water to the water purifier, use the regulator 14.

The percentage ratio of the mass of melt water received to the total mass of water is 60-80%, and the whole process from the start of loading raw water and the release of this water in the form of melt takes at least 5-8 hours. The performance of the proposed water purifier depends on its overall dimensions and is for a volume of 2-4 l 5 hours, for a volume of 5-8 l - 8 hours.

The proposed design of the water purifier allows you to increase productivity by increasing the efficiency of the process of obtaining melt water, to increase the degree of purification due to the exclusion of the possibility of mixing melt water with impurities (brine).
