Abstract

Use: for domestic water treatment. SUMMARY OF THE INVENTION: a filter load is placed in a housing with removable upper and lower covers. The filter is equipped with a flow rate controller for purified water, which is made in the form of horizontal microchannels on the inner surface of the upper cover with an elastic membrane “2 z-op”, placed on them 2 ill.

Description

The invention relates to small-sized devices for treating domestic water,

Closest to the proposed cartridge for the preparation of water (Pat „GDR No. 228801, class 0 02 F 1/18, 1985), consisting of a housing with removable upper and lower covers, granite ionite and porous drainage walls placed inside it

A disadvantage of the known technical solution is the low quality of water purification, due to the fact that the purified water is passed through the filter at an unsuitable speed, and also because the granular loading of the filter cartridge can become clogged by mechanical impurities contained in the purified water, which reduces the efficiency cleaning In addition, porous drainage walls have very small pores - from 0 to 0.1 mm, which makes their mass production difficult

The purpose of the invention is to improve the quality of water treatment and ease of use

The goal is achieved by the fact that a regulator of the flow rate of the purified water is installed inside the removable cover, made in the form of horizontal microchannels on the inner surface of the top cover with an elastic membrane superimposed on them. Thus, the objective of the invention is achieved, namely, improving the quality of cleaning by maintaining an optimal filtering rate, which remains almost constant when the water pressure changes due to a change in the gaps of the microchannels

The goal is also achieved by the fact that the space above and below the granular charge is filled with pieces of porous elastic material, the size of which is larger than the size of the holes and the drainage wall. This improves the quality of cleaning, since mechanical impurities are retained in the pre-filter without getting into the grain filter , which increases its efficiency When used as a granular load activiro

When using coal, ash dust is not allowed to enter the filtrate, which also improves the quality of water treatment.

This goal is achieved by the fact that on the upper conical cover there are grips for fixing the supply pipe with a nozzle for connecting to a water tap and a discharge pipe with a fitting, as well as hinges for attaching the filter to the wall. This achieves the aim of the invention is to increase the usability - since the filter is attached to the wall, it can be removed without unfastening

On Fig shows a diagram of the filter cartridge, section; in Fig.2 is a view of the top hu (nozzles are not conventionally shown)

The filter cartridge consists of a housing 1, with a removable upper 2 and lower 3 covers and a granular load placed inside the housing 0. In the upper cover 2 there is a regulator 5 for the flow of purified water, made in the form of horizontal microchannels 6 on the inner surface of the lid with the cover elastic membrane 7 The space above the load 8 and under the load 9 is filled with pieces of porous elastic material, for example, polyurethane foam. 1-5 cm in size. The drainage walls 10 have large openings times

up to 0.9 cm "On the upper conical cover there are clamps 11 for fastening the supply pipe 12 with a nozzle for connecting to the water tap 13, as well as a gripper 14 for fixing the discharge pipe 15 with fitting 1b0. On the upper cover there are also loops 17 for attaching the filter to Wall

The filter cartridge works as follows: The nozzle 13 is mounted on a water tap, and the nozzle 16 is placed in a receiving tank. A water tap is opened, and water through the pipe 12 enters the filter 1, it is cleaned of mechanical impurities and passes through the ion exchanger, and moves through the ion exchanger k, desalinates 0 Next, pass through filter 8 (where

coal dust is delayed, if coal is used as the charge k) and the flow regulator 5 with a free flow rate, it is poured into the receiving tank through the pipe 15.

If the protective effect of the anion exchange resin (activated carbon) is blocked and the charge is replaced, the load is replaced as well. filters 8 and 9 are removed from the filter and washed by hand with clean water, and then loaded back into the filter.

The principle of operation of the regulator of the flow rate of treated water is as follows0 A membrane with elasticity presses .. to the microchannels with water pressure. Water flows into microchannels, flowing around the perimeter of the membrane. As the water pressure increases, the membrane is pressed, / the channels are stronger, the lumen of the microchannels decreases, and, accordingly, the water flow is equalized, since at higher pressures it moves along the microchannels with greater speed
