Description

The invention relates to household filters for filtering mechanical and dissolved impurities of water from artesian wells, other natural bodies of water, wells, a water tower and for the post-treatment of city water.

Known is a combined cottage filter for fine water purification Honeywell HS10A, equipped with a backwash system for the mesh. An integrated check valve protects against backflow and back pressure. An integrated pressure reducing valve protects the filter from overpressure, see http://aqua.eliteman.ru/kottedzhnyie-filtrvi-dlya-ochistki-vodyi/130.

The multi-module cottage filters of CONVERSION JSC of various capacities are known, see http://noutes.basketfood.ru/drinks/a/2627, AKVAFOR cottage filters with a capacity of up to 16 l / h, see http://teploarsenal.com. ua / akvafor.html, etc.

As a rule, in these filters one module removes one impurity whose concentration exceeds the permissible one. In ecologically disadvantaged regions, the amount of impurities with a high concentration can exceed ten units, and the number of modules should accordingly exceed ten units. Such filters occupy very large areas. Modules contain chemical reagents, which, after exhausting the resource of the module, must be regenerated by other reagents.

Cottage filters do not control the ingress of cleaning reagents into the purified water pipeline and, as a result, reagents that purify water and reagents that regenerate cleaning reagents can enter the food ration of the cottage filter owner.

Closest to the claimed cottage filter is a universal automatic multi-purpose regenerated cottage filter ECOWATER ETF2100PF12 with an electronic control unit, with various filter module fillings that remove dissolved and mechanical impurities, 1588 mm high, 356 mm wide, 356 mm deep, with a capacity of up to 1.8 m ³ / h (see http://aqua.eliteman.ru/kottedzhnyie-filtryi-dlya-ochistki-vodyi/130).

The disadvantages of the filter include a bulky design, low productivity, the need to use chemical reagents (fillers) to remove impurities of the treated water, the need for regeneration of fillers by other chemical reagents, and the lack of guarantee that the chemicals used in the system will not get into the consumer’s diet.

The objective of the invention is the creation of a small cottage filter with a universal filtering module (one module for all impurities), regenerated without chemical reagents.

The problem is solved in that the filter module is made of any pipe and is equipped with a removable block of ceramic plate tangential filters with longitudinal parallel channels, while the cottage filter is equipped with an ultrasonic generator, the strictor of which is installed in the stream of purified water in the pipeline in front of the filter module, and an accumulator at the outlet clean water filter module.

To disinfect purified water, the cottage filter is complemented by a colloidal silver generation unit.

A block of ceramic plate tangential filters with longitudinal parallel channels delays suspensions, including colloidal ones. Ultrasonic vibrations cause dissolved impurities to precipitate, which is trapped in the cavity of the filter module housing by a block of ceramic plate tangential filters and flows out of the cavity continuously through a drainage valve into the sewer. The hydraulic accumulator accumulates purified water under pressure and periodically, at the command of the electronic unit, presses it out with reverse current under pressure into the plate channels of the block of ceramic plate tangential filters of the filter module. At the same time, water seeps into the cavity of the filter module housing along the pores of the plates and discharges dirt that has settled in the pores into the cavity of the housing and through the drainage valve to the sewer. The colloidal silver generation unit can be connected both to the input to the filter module and to its output.

Figure 1 shows a General view of the cottage filter. Figure 2 shows a filter module.

The cottage filter, Fig. 1, is equipped with a hydraulic accumulator 1, on which a control electronic unit 2, a filter module 3 with shut-off valves with an electric actuator 4, 5, 9, with a clean water outlet 6, a drainage valve 7 and a purified water inlet 8 are fixed ; An ultrasonic generator 11 is installed on the hydraulic accumulator frame, the stricker of which (not shown in the drawing) is integrated into the stream of purified water in the pipeline 10 that supplies the purified water in front of the filter module. The colloidal silver generation unit is not shown in the drawing. The maximum performance of the filter module is 0.8 m ³ / h. To increase the yield of pure water, several filter modules can be installed on the accumulator. Dimensions of the basic cottage filter with a hydraulic accumulator with a capacity of 18 liters 630 × 350 × 350 mm. On a gyroaccumulator with a capacity of more than 18 liters, you can install more filter modules. The resource of ceramic plate tangential filters with longitudinal parallel channels is practically unlimited.

The filter module, figure 2, includes a housing 12 with a clean water outlet 6, a drainage valve 7 and a purified water inlet 8, comprising a removable block 13 of ceramic plate tangential filters with longitudinal parallel channels 14.

The filter works in the following modes.

1. Cleaning mode. The shut-off valve 9 at the entrance to the filter module is open, the shut-off valve 5 at the outlet of the filter module is closed, the shut-off valve 4 at the entrance to the accumulator is open. The cleaned liquid enters through the pipeline 10, which supplies the water to be purified, where, under the influence of ultrasonic vibrations of the strictor, the dissolved impurities precipitate from the water. Water with sediment through the stopcock 9 enters the cavity of the filter module housing. Hence, pure water, seeping through the pores of the walls of the plates of the block of ceramic plate tangential filters, enters the channels of the plates and through the permeate discharge unit 6, the shut-off valve 5 and shut-off valve 4 are supplied to the consumer, and impurities flow continuously from the cavity of the filter module housing through the drain valve 7 down the drain. At the same time, purified water enters the accumulator, which is filled until the network pressure is created in it. The duration of filtration is 30-60 minutes and regeneration is 30-40 seconds.

1.1. Regeneration mode. The ultrasound generator is off. Shut-off valves 4 at the entrance to the accumulator and 9 at the entrance to the filter module are closed. The shut-off valve 5 at the output of the filter module is open. The permeate accumulated in the gyroaccumulator is ejected under pressure into the filter module through the shut-off valve 5 at the outlet of the filter module and the permeate output unit 6 into the plate channels of the ceramic plate tangential filter unit with longitudinal parallel channels and penetrates through the pores of the channel walls into the cavity of the filter module housing, squeezing the accumulated into pores of impurities and through the drainage valve 7 of the filter module is discharged together with impurities into the sewer.

Thus, a small-sized regenerated cottage filter was created that separates dissolved impurities and suspensions, filtering artesian, well water, natural reservoirs, a city water supply mechanically without the use of chemical reagents, with almost unlimited resource and high performance.

Mechanical filtration guarantees the food ration of the owner of the cottage filter from chemical agents.
