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 water freezing with an annular freezer located in series in a longitudinal vessel, an area for displacing impurities from the ice front and a concentration of impurities in the form of a brine, and a zone for transferring water from solid to liquid with an annular heating element, separate nozzles to remove impurities in the form of brine and melt drinking water, located in the lower part of the vessel (FR 2858607 A1, 02/11/2005).

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 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, and a zone for the transition of water from solid to liquid with an annular heating element, separate nozzles for removing impurities in the form of brine and melt drinking water, located in the lower part of the vessel, AC drive unit openings of the core of frozen water in the form of a threaded ring on the inner surface and with a gear drive of rotation, as well as an uncoupling device in the form of a pipe with an “annular cutting part (patent RU No. 2368571, C02F 1/22, B.I. No. 27, 2009) .

A disadvantage of the known water purifier is low productivity due to the structural imperfection of the drive device for moving the frozen water rod made in the form of a threaded ring, since the thread inefficiently cuts into the frozen water rod, the ice breaks and as a result the thread slips, which reduces the performance of the known water purifier.

The technical problem to which the invention is directed, is to increase productivity.

This goal is achieved by the fact that in the proposed technical solution, including a water purifier for producing thawed drinking water, which includes a zone of water freezing with an annular freezer located in series in a longitudinal vessel, a zone for displacing impurities from the ice front and concentration of impurities in the form of brine, a transition zone water from solid to liquid with an annular heating element, separate nozzles for removing impurities in the form of brine and melt drinking water, located in the lower part with a vessel, a drive device for moving a frozen water rod in the form of a ring with a thread on the inner surface and with a gear drive of rotation, as well as an uncoupling device in the form of a pipe with an annular cutting part, according to the invention, a heating element is mounted inside the threaded ring.

The execution of a threaded ring with a built-in heating element makes it possible to ensure the movement of the frozen water rod onto the uncoupling device with the lowest energy costs, since the heating element thaws the ice and the ring thread moves the frozen rod without additional resistance.

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 freezing zone of which an annular freezer 2 is installed, behind it is mounted a drive device for longitudinal movement of the frozen rod 3, made in the form of a ring 4 with a thread on the inner surface that engages with the frozen rod 3 in the longitudinal vessel 1 A heating element 5 is mounted inside the ring 4, providing heating of the ring 4 to a temperature of 80-90 ° C. The outer surface of the ring 4 has a gear drive of rotation 6. In the displacement zone of impurities, a disconnecting device in the form of a pipe 7 is placed in the center of the frozen rod 3, which has a cutting part in the form of a ring gear 8 at the inlet and an expanding profile forming the outlet pipe 9 at the exit to remove impurities in the form of brine into the sewer 10. In the zone of transition of water from solid to liquid, an annular heating element 11 is located. To melt water, there is a nozzle 12, opposite which there are tanks 13 for collecting but the finished product.

To supply water to the water purifier, device designs with regulators 14 are used.

The principle of operation of the device is the continuous production of melt water according to the 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 by means of a thread on a ring 4 rotating around its axis (from a gear drive of rotation 6) is continuously pushed onto the cutting part 8 of the pipe 7, due to which there is a mechanical separation of impurities in the form of brine (such as compacted snow) from pure ice. Due to the fact that the contact of the surfaces of the frozen rod 3 and the thread is heated from the heating element 5, they provide reliable displacement of the frozen rod along the axis of the vessel 1. Separated impurities pass through the outlet pipe 9 to the sewer 9. After releasing the frozen rod 3 from the central part, it 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 50-70%, 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 12-18 hours. The performance of the proposed water purifier depends on its overall dimensions and is 12 hours for a volume of 4-8 l, 18 hours for a volume of 5-8.

The proposed design of the water purifier can improve productivity due to the continuity of the process of obtaining melt water, by increasing the reliability and speed of movement of the frozen rod.
