Description

The proposed utility model relates to the field of drinking water supply, specifically to devices for the electrochemical treatment of drinking water, and can be used in domestic conditions for the purification of tap water, as well as for the purification of natural waters and bringing the physicochemical and organoleptic properties to meet the requirements for drinking water.

Electrochemical methods allow the most effective purification of water from anthropogenic impurities (Miklashevsky N.V., Korolkova S.V. Pure water. Purification systems and household filters. St. Petersburg: VHV-Saint Petersburg, publishing group Arlit, 2000, p. . 154).

A device is known that implements the method of electrochemical purification of drinking water according to patent RV 2043308, which contains a container in which a packet of electrodes with a soluble anode is placed, as well as a container with a filter element. The device also contains a power and control source with a step-down transformer and a rectifier connected to the AC network and to the electrodes of the device.

It is also known that there are devices for electrochemical purification of drinking water (utility model) according to the patent No. 36424 containing a power source, a reactor vessel with a packet of soluble electrodes located in it, and a filter vessel with a filter element; the buoyant open buoyant is installed vertically in the upper part of the reactor vessel easily removable cone with a vertical handle on top, the filter tank is equipped with an easily removable filter element for fine filtering, and above the reactor tank A funnel with an annular magnet mounted on a drain pipe is installed.

It is also known that a device for electrochemical purification of drinking water (utility model) according to patent No. 140642 is a household device for electrochemical purification of drinking water, containing a reactor vessel with an electrode block package placed inside it, guide racks are made perpendicular to the bottom of the reactor vessel on the inside of its side walls with grooves in which the electrode plate package is placed and fixed in the package, while the package of the electrode block is mounted by attaching the contacts of the electrode plates in the well znyh openings bottom of the reactor vessel, and the guide rack with grooves formed together with the capacity of the reactor during its manufacture by injection molding.

The specified device according to patent No. 140642 for the maximum number of similar essential features (reactor capacity with an electrode package located in it, mounting electrodes in an electrode package, rigid fixation of the cathode plates at a distance calculated from each other, guide racks with slots) is taken as the prototype model.

The disadvantage of the device selected for the prototype is the complexity and high cost of the injection mold for manufacturing the reactor by injection molding, as well as the low adaptability of the assembly of the package of the block of electrodes.

The purpose of this technical solution is:

- improving the manufacturability of the reactor vessel;

- facilitating the installation of the electrode plates in the block of electrode plates.

The essence of the proposed solution lies in the fact that the cover for combining the electrode plates into a package of the electrode block is made by injection molding separately from the reactor vessel. The installation of the electrode plates in the package of the block of electrodes is carried out by moving and installing each of the plates inside the cover along the guide grooves of the side walls of the cover.

The introduction as declared features of the cover with side walls in the form of guide racks with grooves simplifies the injection mold and reduces the cost of manufacturing the reactor vessel by injection molding, provides the assembly of the electrode plates in the block of electrode plates outside the reactor vessel, which simplifies the subsequent installation of this block when installed in reactor.

When conducting a patent search, it was found that a solution similar to the proposed one is missing. Therefore, we can consider the proposed technical solution corresponding to the level of the utility model.

The essence of the proposed technical solution is illustrated by graphic materials, where in FIG. 1 shows a diagram of the device of the prototype, in FIG. 2 is a diagram of a portable case for combining electrode plates into a package of an electrode block; FIG. 3 is a bottom view of a portable case; FIG. 4 top view of the carrying case.

In the prototype (Fig. 1), the placement of the electrode plates in the block of the package of electrodes 2 is carried out in the grooves 4 of the guide racks 1, made in conjunction with the reactor vessel 3.

Unlike the prototype, in the proposed device, separately from the reactor vessel, a portable case 6 is made (Fig. 2). The side walls 7 of the portable case 6 (Fig. 2) serve as guide racks 1 (Fig. 1) for placing 4 electrode plates in their grooves in order to combine the electrode block into a package. The stops 8 (Fig 2) on top of the grooves 4 of the side walls 7 of the portable cover 6 are intended to limit the free movement of the cover on the plates of the electrode block. The fixation of the package of the block of electrodes to the bottom of the reactor is carried out similarly as in the prototype (Fig. 1) by the contacts of the electrodes.

The proposed device for placing and combining the electrode plates in the package of the electrode block using a portable case significantly simplifies the design, increases manufacturability and reduces the cost of manufacturing the reactor vessel, assembly (disassembly) of the electrode block package and their preventive maintenance.

The tests of the samples of the portable cover showed the manufacturability of its manufacture, ease of assembly (disassembly) in the package of the block of electrodes, interchangeability of the covers. Testing of a serial sample of the PVVK electrochemical cleaning device with the installation of electrode plates combined into a block of electrode plates with a portable case showed that the technological properties of treated water after the implementation of the proposed technical solution remain high quality, confirmed by certificate No. C-RU.H003.A.00355 from 05/14/2012.
