Abstract

The utility model relates to a novel filter mainly composed of a filter housing, a filter cover, a filter ring, and two or more than two filter cartridges. Under the condition of not increasing volume, the utility model has the advantages of increase of filtering area, larger throughput of the filter, housing material saving, small occupation area of the filter, prolonged using period, convenient maintenance, application for filtering of liquid and gas, etc.

Description

A kind of filter

The utility model belongs to the liquids and gases filtration art.This is a kind of under the situation that does not increase filter volume, has increased the filter of filter area.

Existing filter cartridge type filter mainly is to utilize its single garden column type surface of filter medium to filter, thereby exists because filter area is less defective such as the treating capacity of filter is little.The purpose of this utility model is exactly in order to overcome the above-mentioned defective of existing filter cartridge type filter, promptly under the situation of filter cylinder constancy of volume, realized the increase filter area, improved the treating capacity of filter, and have and reduce filter and take up an area of the space, save the housing raw material, life cycle prolongation, characteristics such as easy to maintenance.Filtration applicable to liquids and gases.

The utility model mainly is made of the filter housings filter cylinder different with two or more diameters, filter lid, filter ring.It is characterized in that: the upper end of center filter cylinder is combined as a whole with the filter lid, the lower end that the logical filtering ring in the lower end of center filter cylinder is adjacent outer filter cylinder is combined as a whole, and upper end that should the skin filter cylinder is combined as a whole by the upper end of another filter ring filter cylinder adjacent with another and this skin filter cylinder again, by that analogy, make the different filter cylinder of a plurality of diameters be combined into an integral body, form a labyrinth type and filter wire side, and filter housings is separated into two spaces up and down.During work, after liquid (gas) the body inherent filtration device upper end import of filtered enters enclosure interior, filter wire side by labyrinth type and finish filter process, the liquid after the filtration (gas) body enters the lower end outlet of filter housings and discharges.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.Accompanying drawing is the special case that designs according to principle of the present utility model, i.e. the filtration device structure schematic diagram that is made of two filter cylinders.1. support rings among the figure, 2. outer filter cylinder, 3. the filter lid, 4. the center filter cylinder, 5. the filter ring, 6. filter housings, a. import, b. outlet, A. are liquid to be filtered (gas) body, liquid (gas) body of B. for having filtered.

Describe a kind of structure and operation principle of filter in detail below in conjunction with accompanying drawing.

As shown in drawings, the upper end of center filter cylinder 4 is covered 3 with filter and is combined as a whole, and the logical filtering ring 5 in the lower end of center filter cylinder 4 is combined as a whole with outer filter cylinder 2 lower ends, and the upper end of outer filter cylinder 2 and support ring 1 are combined as a whole.From accompanying drawing as can be seen, above-mentioned parts constitute an integral body, form a spill labyrinth type and filter wire side, and filter housings 6 is separated into two spaces up and down.During work, liquid to be filtered (gas) body filters wire side through the spill labyrinth type and filters the discharge from outlet b from the upper end that import a enters filter housings 6.Thereby finish the filtration of liquid (gas) body.In implementation process, import a, outlet b oppositely connect also and set up.

Claims

1. a filter mainly is made of the filter housings filter cylinder different with two or more diameters, filter lid, filter ring; It is characterized in that: the upper end of center filter cylinder is combined as a whole with the filter lid, the lower end that the logical filtering ring in the lower end of center filter cylinder is adjacent outer filter cylinder is combined as a whole, and upper end that should the skin filter cylinder, upper end by another filter ring and another adjacent outer filter cylinder is combined as a whole again, by that analogy, make the different filter cylinder of a plurality of diameters constitute a complete integral body, form a mazy filtration wire side, and filter housings is separated into two spaces up and down.
