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.

Also known is a device for electrochemical purification of drinking water (utility model) according to patent No. 36424, containing a power source, capacity

a reactor with a package of soluble electrodes located in it and a filter container with a filter element; a vertically movable, easily removable inverse cone with a vertical handle mounted buoyantly mounted in the upper part of the reactor vessel, the filter tank is equipped with an easily removable fine filter element, and above the reactor tank a funnel with a ring magnet mounted on the drain pipe is installed.

The specified device according to patent No. 36424 for the maximum number of similar essential features (a container with a package of electrodes with a soluble anode, a container with a filter element, an easily removable inverse cone) is taken as a prototype model.

The disadvantage of the prototype device selected is the low efficiency of removing sludge collected at the neck of the vessel with the electrode package due to deviations of the inverse cone from the vertical when moving it inside the reactor vessel and, as a result, excess sludge remaining in the reactor vessel on the filter element and a significant reduction filter element life before regeneration.

The purpose of this technical solution is to increase the efficiency of removing sludge from the reactor vessel and, as a result, to significantly reduce the load on the filter element, i.e. increase in its resource.

The essence of the proposed technical solution lies in the fact that in the upper part of the reactor vessel containing the package of electrodes, guides are placed on the inner side of the walls, and grooves are placed symmetrically on these movable cones with these guides, which ensure stable cone movement along the guides inside the reactor in the vertical direction. In addition, the top of the movable cone is truncated by such a value that when moving the cone in a vertical direction along the guides into the reactor, the lower point of its movement corresponds to the stop of the truncated cone in the block of electrode plates.

The introduction of guides inside the upper part of the reactor and grooves on the movable cone as declared features ensures the stability of the cone in a vertical position when moving it inside the reactor, which, in turn, ensures cone tank filling with slurry at the same time, lifting and removing sludge without splashing. Cone trimming ensures the cone is fixed at the bottom point and eliminates the possibility of impact

the top of the cone between the plates of the electrode block, which would be fraught with a change in the distance between the plates and the termination of the device.

The introduction, as claimed features, of the fastening structure of the filter element inside the filter container is simple both in technical design and for servicing the filter element by the consumer.

The calculated level of pouring water into the reactor vessel in combination with the calculated gap between the base of the inverse movable truncated cone and the inner wall of the reactor vessel ensures maximum collection of sludge by a cone when removing sludge from treated water without splashing it from the reactor vessel.

The calculations were made for different levels of water filling and for the gaps between the base of the inverse movable truncated cone and the inner wall of the reactor vessel from 2 mm to 12 mm. As calculations and subsequent experiments showed, cones with a gap between their bases and the inner wall of the upper part of the reactor vessel 5mm-6mm are most effective in removing sludge.

The electrodes are fastened to the electrode block package by special latches that fix the cathode and anode plates at a distance calculated from each other.

The reactor, in order to facilitate its maintenance and movement, is installed in a special container.

From the prior art, no solutions have been identified that have features that match the distinctive features of the proposed technical solution. Therefore, we can assume that the proposed technical solution corresponds to the level of the utility model.

The proposed device, as well as the prototype (Fig. 1), contains a power source, a reactor vessel 2 with an electrode package 3, a filter vessel 4 with a filter element 5 installed in the reactor with the possibility of vertical movement and having a buoyancy with an easily removable inverse cone 6 open from above with vertical handle 7.

In contrast to the prototype, in the proposed device in the upper part of the reactor vessel 2 (FIG. 2 and FIG. 3) guides 10 are placed, and on the reverse cone 6 (FIG. 4 and FIG. 3), grooves 11 are mounted symmetrically to these guides, the filter element is attached 5 to the bottom of the filter tank 4 (Fig.6 and Fig.7) is carried out using a hollow tube 12, to the end of which a plate 13 is fixed, for example a circle, the hollow tube 12 has through holes 14, from the opposite end the tube is equipped with a thread 15 with a nut 16 for fixing the filter element 5 to the filter bottom tank 4, the reactor itself is placed in the container 17 (Fig. 8) for the purpose of ease of maintenance and movement of the reactor. The electrodes are attached to the package of the electrode block (Fig. 12) by latches 20 (Fig. 11). The side lobes 21 of the latches 20 (Fig. 11) are installed in the holes 22 of the cathode plates 18 (Fig. 9, Fig. 12). The anode plate 19 (figure 10) is fixed by the Central groove 23 of the latches 20 (figure 11). Received a rigidly fixed package of the block of electrodes (Fig) with fixing the plates of the electrodes (18 and 19) at a calculated distance from each other.

The work of the proposed device is completely similar to the work of the prototype. After exposure of the sludge, having a groove 11, the truncated return cone 6 is immersed along the guides 10 inside the vessel of the reactor 2 until it stops in the electrode assembly 3. The sludge with some volume of water is drained into the cone 6. After the discharge, the cone 6 is removed along the guides 10 from the reactor 2. The sludge is drained, the cone is washed with running water.

The fastening of the filter element 5 to the bottom of the filter tank 4 is shown in Fig.7. The filter tank 4 is installed on the storage (glass jar, bucket or any other container). Water is poured into the filter tank 4 from the reactor 2, after filtering (Fig. 7) with the filter element 5, water enters the storage tank through the opening 14, and water flows from the storage tank (glass jar, bucket, etc.) to the consumer.

The distinguishing features proposed in the formula (utility model) were implemented by the authors in a serial model of a BSL-Med series drinking water purification device (BSL-Med-1 model), certificate of conformity No.ROSS RU.ME 96. VO 1901 dated 05.02.2007 city (Gosstandart of Russia), and allows us to draw conclusions about the high efficiency of the quality of collection and removal of sludge from the surface of the reactor vessel. In this case, the consumer does not need to think about the depth of immersion of the cone in each specific situation. The proposed fastening of the filter element contributes to its tight fixation to the bottom of the filter container, which, in turn, contributes not only to a high-quality filtering process, but also to the subsequent ease of maintenance of the filter element by the consumer. Placing the reactor in a special container facilitates ease of maintenance and movement by the consumer.
