Description

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

A device for water purification is known, including a zone of freezing water located in series in a longitudinal vessel, a zone of displacing impurities from the ice front and a zone of transition of water from solid to liquid state (FR No. 2858607 A1, 02/11/2005).

The disadvantage of such devices is the insufficient quality of water treatment associated with the technological complexity of the cooling and heating process.

Closest to the proposed device is a water purifier for producing melt drinking water, including a zone of water freezing with an annular freezer located in series in a longitudinal vessel, an area for displacing impurities from the ice front and concentration of impurities in the form of brine, an area for the transition of water from solid to liquid with ring heating element, separate nozzles for removing impurities in the form of brine and melt drinking water, a drive device for longitudinal movement of frozen erased reaping water in the form of rollers with serrated surfaces meshed with a frozen rod through slots in the vessel and located around the perimeter of the longitudinal vessel, a disconnecting device, 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 ( RF patent No. 2312817, С02F 1/22, BI No. 35, 2007).

A disadvantage of the known water purifier is the low productivity and degree of purity of water due to structural imperfections caused by high resistance to friction of the frozen water rod against the walls of the longitudinal vessel, which leads to slipping of the rollers relative to the frozen rod.

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

This problem is achieved by the fact that in the proposed technical solution, comprising a zone of water freezing with an annular freezer arranged sequentially in one longitudinal vessel, an area for displacing impurities from the ice front and a concentration of impurities in the form of a brine, an area for the transition of water from solid to liquid with a ring heating element, separate nozzles for removing impurities in the form of brine and melt drinking water, a drive device for the longitudinal movement of a frozen water rod in the form of rollers with a cog the surfaces engaging with the frozen rod through the slots in the vessel and located around the perimeter of the longitudinal vessel, a disconnecting device, and for the removal of 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, rollers with gear surfaces have elastic elements that are installed with the possibility of pressing the rollers to the frozen rod.

Rollers with gear surfaces, equipped with elastic elements that are mounted with the ability to press the rollers against the frozen rod, ensure reliable contact of the rollers with the frozen rod during operation of the device. In this regard, the rollers do not slip and provide reliable movement of the frozen rod, which increases the productivity and degree of purity of the water.

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 of fluoroplastic material, in the freezing zone of which an annular freezer 2 of known design and principle of operation is installed, behind it is mounted a drive device for longitudinal movement of the frozen rod 3, made in the form of rollers 4 with gear surfaces that engage with the frozen the rod 3 through the slots 5 in the longitudinal vessel 1, which are located around the perimeter of the longitudinal vessel 1. In the displacement zone of impurities is placed in the center of the frozen rod 3 disconnecting device in the form of a pipe 6, which has a cutting part 7 at the inlet and an expanding profile at the outlet, forming an outlet pipe 8 for removing impurities in the form of brine into the sewer 9. In the zone of transition of water from solid to liquid, an annular heating element 10. To output the melt water there is a pipe 11, opposite which there are containers 12 for collecting the finished product.

The rollers 4 with gear surfaces have elastic elements 13, which are installed with the possibility of pressing the rollers 4 to the frozen rod 3.

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 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 the water (i.e. brine) has time to flow out of intercrystalline 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. 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 10, 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 11, melt water enters the tank 12. To supply the required amount of water to the water purifier, use the regulator 14. The rollers 4 with gear surfaces by means of elastic elements 13 are constantly pressed against the frozen rod 3, regardless of its surface condition, which ensures the movement of the frozen rod 3 on the cutting part 7.

The percentage of the mass of melt water received to the total mass of water is 50-70%, and the whole process from the start of loading the raw water and the release of this water in the form of melt takes at least 10-14 hours. The performance of the proposed water purifier depends on its overall dimensions and amounts to 11 hours for a volume of 2-4 liters, 18 hours for a volume of 5-8.

The proposed design of the water purifier allows to increase productivity due to the continuity 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).
