RU58050U1 - CARTRIDGE FILTER FOR CLEANING WATER - Google Patents

Abstract

The utility model relates to devices for cleaning liquids, in particular, to filters for treating drinking water, and can be used in the food and medical industries. The essence of the utility model: a cartridge filter for water purification comprises a cylindrical body with an inlet for supplying purified water and an outlet for purified water, and a filter element located inside the housing made of a perforated support tube on which a sorption-active filtering coil is placed material based on a fibrous sheet of artificial or synthetic polymeric material modified with nanosized particles of aluminum oxide hydrate, intended for For fine purification and purification of water from microorganisms, while it is located coaxially in the housing; additionally, inside the tube on which a roll of sorption-active filtering material is wound, an additional filtering medium is formed, formed from a fibrous material, intended for rough water treatment.

Description

The utility model relates to devices for cleaning liquids, in particular, to filters for treating drinking water, and can be used in the food and medical industries.

Known cartridge filter for liquids (DE 4401116, 1997), including an internal perforated support tube, wrapped in a base mat of porous material. The individual turns of the mat are separated by a layer of a powdery filter medium.

The disadvantages include the presence of a powder layer, which limits its use, since there is a large ablation of the powder medium, which in turn reduces the quality of liquid filtration.

As a prototype selected (RU 18648 U1, 2001), a portable filter for water purification, comprising a housing with a bottom, a discharge pipe, means for supplying purified water and a filter element in the form of at least one plate of a ceramic plate membrane tangential filter having at least one longitudinal channel, and installed in the housing with the formation of a sealed cavity for collecting purified liquid, while the outlet pipe is in communication with the cavity for collecting purified water, the means for supplying purified water about in the form of a pipe attached to the opposite part of the housing, and at the bottom there is at least one hole or slot for draining under-treated water, while it is equipped with a union nut with a sealing seal to connect the filter to the camping flask during movement person.

The disadvantages of the prototype include its high cost, as well as the low quality of purified water, due to the lack of sorption properties of the used filter material.

The objective of the utility model is to improve the quality of cleaning and ease of use in any conditions.

The problem is achieved in that, like the well-known, the claimed cartridge filter for water purification contains a cylindrical housing with an inlet for supplying purified water and an outlet for purified water, and a filter element located inside the housing.

What is new is that the filter element is located coaxially in the housing and is made of a perforated support tube, inside of which there is a filtering agent for rough water purification formed of fibrous material, while a sorption-active filter material wound into a roll is placed on a perforated support tube based on a fibrous sheet of synthetic polymer material modified with nanosized particles of aluminum oxide hydrate, designed for fine water purification and purification water from microorganisms.

In addition, a shoulder is made in the upper part of the housing for fixing the cartridge filter inside the inlet of the tank for purified water.

In addition, the housing and perforated support tube are made of plastic.

The cartridge filter for water purification (see Fig.) Includes a housing 1, in the upper part of which there is an outlet for purified water 2, in the lower part of the housing there is an inlet for purified water 3, and a collar 4 for fixing the housing to the tank with purified water 5, a filter element is installed in the housing, consisting of a support perforated tube 6 on which a sorption-active material 7 is wound, filtering means 8 is located inside the perforated support tube.

14 layers of sorption-active material 7 with a thickness of 0.14 mm are wound on a perforated support tube 6 made of low-pressure polyethylene, which is a filter material based on a FPA-15-2.0 grade Petryanov filter, modified with nanosized particles of aluminum oxide hydrate. The perforated tube 6 may have a diameter of 10 to 35 mm (preferably 13 mm) and a height of 30 to 60 mm (preferably 45 mm). Then, a fibrous polypropylene material with a filtering ability of 20

microns. Then all this is inserted into the housing 1, made of polypropylene, closed with a lid with a hole and pressed.

The device operates as follows.

Contaminated water is placed in the container 5, in the inlet of the container which is placed and secured with the collar 4 of the cartridge filter housing 1. The collar 4 is pressed by a stopper from the container. Next, the water passes sequentially through the filtering means for rough cleaning 8, where it is cleaned from mechanical impurities, ferrous and ferrous iron, heavy metals, partial softening, and then through the sorption-active material 7 is wound in the form of a roll onto a perforated support tube 6, which is the disinfection of water. Purified water leaves the outlet 2 of housing 1. As the filtered mass accumulates on the filter materials, as can be judged by the decrease in its water transmission rate (initial filtration rate of 0.25 cm / s), the cartridge filter is washed or replaced.

The proposed filter allows you to purify water from mechanical impurities, particles of a fine dispersed phase and colloidal formations, heavy metals and iron ions, high molecular weight organic compounds and microorganisms.
