Abstract

The utility model relates to a pressure filter, which comprises a top shell, with the two sides of the top being provided with an air inlet and air outlet respectively and the bottom being provided with an opening communicated with the air inlet and air outlet, a stream guidance plate arranged on the bottom side of the top shell, a bottom shell with one chamber arranged below the top shell and a filter element, which is barrel-shaped, arranged on the bottom side of the stream guidance plate and located in the chamber of the bottom shell, wherein the filtration element has several grooves, arranged on the peripheral surface of the filtration element. Thus the pressure filter provided by the utility model can increase the surface area of the peripheral surface of the filtration element, and then raise the contact area of the air with the filtration element, with much better filtration effects.

Description

The pneumatics filter

Technical field

The utility model is relevant with the pneumatics assembly, particularly about a kind of pneumatics filter.

Background technology

The pneumatics filter is used to filter the compressed air that enters air compressor machine, and its purpose is in the filtering compressed air parts are had dysgenic moisture content and impurity, makes the air after the filtration dry and clean.The principle of commonly using the pneumatics filter is to allow the compressed air filter core of flowing through, and impurity contained in the compressed air and moisture content are stopped by this filter core, by the clean dry air that is of this filter core.

Wherein, the contact area of filter core outer peripheral face and air is big more, and the filter effect of filter core is good more, yet the filter core outer peripheral face of commonly using the pneumatics filter is a smooth surface, and the contact area of itself and air only limits to the smooth surface of outer peripheral face, and filter effect is restricted.

Summary of the invention

At the problems referred to above, main purpose of the present utility model is to provide a kind of pneumatics filter, and it has preferable filter effect.

For achieving the above object, a kind of pneumatics filter provided by the utility model includes: a top shell, the both sides at its top are respectively equipped with an air inlet and a gas outlet, and its bottom is provided with an opening that communicates with described air inlet and described gas outlet; One flow guiding disc, it is located at the bottom side of described top shell; One drain pan, it has a room, and is fixedly arranged on shell below, described top; One filter core, it generally is tubular and is located at described flow guiding disc bottom side, is arranged in the room of described drain pan; It is characterized in that: described filter core has some grooves, and it is located at the outer peripheral face of described filter core.

In the above-mentioned the technical solution of the utility model, the groove of described filter core outer peripheral face is gear-like.

In the above the technical solution of the utility model, the groove of described filter core outer peripheral face is the scroll bar shape.

In the above the technical solution of the utility model, the bottom of described top shell also includes a bar portion and contact lid, and described bar portion passes described flow guiding disc and described filter core in regular turn, sets firmly with described contact lid again.

Adopt technique scheme, the utility model is provided with groove structure by the outer peripheral face at filter core, increases the surface area of filter core outer peripheral face, reaches the contact area that increases air and filter core, improves the purpose of filter effect.

The specific embodiment

In order to describe structure of the present utility model and characteristics in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.

As shown in Figure 1 and Figure 2, the pneumatics filter 10 that the utility model first preferred embodiment is provided, it includes a top shell 20, one flow guiding discs 30, one drain pans 40, and a filter core 50.

The side of top shell 20 in the top offers an air inlet 21, opposite side offers a gas outlet 22, its bottom is provided with an opening 23 that is connected with air inlet 21 and gas outlet 22, be provided with a bar portion 24 in the bottom of top shell 20, bar portion 24 passes flow guiding disc 30 and filter core 50 in regular turn, screw togather with contact lid 25 again and set firmly, the opening 23 of top shell 20 by the edge to the inside equally spaced ring-type be laid with four fins 26.

Flow guiding disc 30 is located at the bottom side of top shell 20, and it has most blades 32, equally spaced is laid in the outer peripheral face of flow guiding disc 30.

Drain pan 40 tops have the room 41 that an opening makes progress, and the outer peripheral face of room 41 split ring edge equally spaced ring-type is laid with four fins 42, and four fins 26 of top shell 20 can screw mutually with four fins 42 of drain pan 40 and set firmly combination.Wherein, the end section of bar portion 24 and contact lid 25 is arranged in the room 41 of drain pan 40.

Filter core 50 generally is tubular, and is located at flow guiding disc 30 bottom sides, is arranged in the room 41 of drain pan 40, and its outer peripheral face is provided with the groove 52 of some vertical straight burrs, makes filter core 50 generally be gear-like.Filter core 50 is sheathed on the bottom side of bar portion 24, one end butt flow guiding discs 30, and the other end is butt contact lid 25 then.

Thus, the air that filtered is handled passes air inlet 21 and enters pneumatics filter 10, and flow in the room 41 of drain pans 40 via blade 32 guiding of flow guiding disc 30, at this moment, the air that filtered is handled can contact with the outer peripheral face of filter core 50, airborne impurity and moisture will be stopped by filter core 50 and be detained in the outer peripheral face of filter core 50, the air that passed filter core 50 can be positioned at the inboard of filter core 50, and continue to flow in past gas outlet 22, pass gas outlet 22 at last and discharge the air of pneumatics filter 10, be clean dry air.Thus, pneumatics filter 10 provided by the utility model can increase the surface area of filter core 50 outer peripheral faces, and then increases the contact area of air and filter core 50, has preferable filter effect.

As shown in Figure 3, the pneumatics filter 60 that is provided for the utility model second preferred embodiment, present embodiment is identical with pneumatics filter 10 primary structures that first preferred embodiment is provided, its difference is: filter core 62 generally is tubular, its outer peripheral face is provided with some grooves 64 that generally are the scroll bar shape, and is different with the structure of the outer peripheral face of filter core 50 in first preferred embodiment.

In sum, pneumatics filter provided by the utility model can increase the surface area of filter core outer peripheral face, and then increases the contact area of air and filter core, has filter effect preferably.
