Abstract

The utility model discloses a built-in filter. The utility model is composed of a vesicular filter element, a filter screen and a vesicular filter outer casing; the filter screen covers on outside periphery of the filter element, and the two form a filter inner core body; the filter inner core body extends into the vesicular filter outer casing, and the filter inner core body and the vesicular filter outer casing are connected in a spigot-and-socket manner. The utility model has advantages of good filtration effect, small volume, convenient installation, easy cleaning, low price, etc.

Description

The internally-inlaid filter

Technical field

The utility model relates to a kind of internally-inlaid filter, belongs to sedimeter.

Background technology

Domestic existing most filters are external, filter at the hilly country special use of vast mountain area is not arranged at present as yet, and the part filter that uses is the metal material manufacturing now, has the production cost height, metallic article is perishable, and in various degree exist mounting technique complexity, pipeline easily to stop up and shortcoming such as easy cleaning not, brought great inconvenience for vast user.

Summary of the invention

For solving the problems of the technologies described above, the purpose of this utility model provides a kind of good filtration effect, cost is low, volume is little, the internally-inlaid filter of easy for installation and easy cleaning.

The technical scheme in the invention for solving the above technical problem is: the internally-inlaid filter, it is made of porous filter core, screen pack and porous filtering shell body, screen pack is overlying on the porous filter core periphery, and the two forms a filtration inner core-body, and this filtration inner core-body stretches in the porous filtering shell body and socket joint connection with it.

Described porous filter core and the corresponding middle part of porous filtering shell body are equipped with the inlet opening.

Described porous filter core and porous filtering shell body are made by the PVC material.

The technological progress that the utility model is obtained is: the filter that two big principles design filters according to rotating centrifugal effect and fine-structure mesh in the hydrodynamics in the utility model system, constitute by porous filter core, screen pack and porous filtering shell body, the mode that the utility model has adopted socket joint to connect makes this device mounting technique simple, easy to operate; Adopt the base material of ageing-resistant PVC material simultaneously,, solved perishable, the problem of easy cleaning not of cost height, metallic article through accurately injection molded as this device; The screen pack that porous filter core covers outward can effectively filter out the impurity in the water, fully reaches the purpose of filtration; Filtration when this device can be applicable to water lift in the water cellar of hilly country, vast mountain area, solved the line clogging problem that vast hill farmer often occurs when carrying out water-saving irrigation, provide good guarantee for hilly country, mountain area vast farmers friend well carries out water-saving irrigation.
