Abstract
The utility model discloses a metal anti-electrostatic type powder recovery filter core. A filter screen of a filter element on an existing powder spraying equipment is made of polyester fiber and is folded into wrinkle shape; the filter screen is an insulator, and the powder floating in a spraying chamber has static electricity, so the powder is easy to be adsorbed tightly on the filter screen. The existing filter element has high powder holding quantity, easy filter screen clogging and short service life. The utility model is provided with a metal conducting layer on the outer surface of the wrinkling polyester fiber filter screen. While in use, powder with opposite charges is attached on the metal conducting layer and is neutralized, so the powder easily falls off from the filter screen; the metal anti-electrostatic type powder recovery filter core has convenient cleaning and high powder recovery rate.
Description
Technical field
The utility model relates to a kind of filter core, particularly a kind of metal anti-static type Powder Recovery filter core.
Background technology
The existing filter element that is used for powder spray coating device is that polyester fiber is folded into the accordion filter screen, and be fixed on discoid top cover and the bottom and support cages outer surface therebetween, after filter is opened, be mingled with the powder that will filter in the air of spray booth attached on the filter screen, because filter screen is an insulator, and floating powder has static in the spray booth, powder can be comparatively firm be adsorbed on the filter screen, even filter core is through shake, it is still very high that it holds the powder amount, stop up filter screen easily, filter core is short service life, the Powder Recovery difficulty.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of long service life, and dust reclaims, clears up metal anti-static type Powder Recovery filter core easily.
The technical scheme that its technical problem that solves the utility model adopts is:
Metal anti-static type Powder Recovery filter core, comprise top cover and bottom, between top cover and the bottom support cages is installed, between top cover and the bottom, the outer end of support cages is provided with accordion polyester fiber filter screen, it is characterized in that: the outer surface of accordion polyester fiber filter screen has the layer of metal conductive layer.
The beneficial effects of the utility model are: because the outer surface of polyester fiber filter screen has the layer of metal conductive layer, when the powder that has static is attached to the metallic conduction laminar surface of filter screen, in the opposite charges between the powder and after very easily come off from filter screen, the powder amount of holding of filter screen is low, be not easy filter screen is resulted in blockage, long service life, dust rate of recovery height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is the I portion enlarged drawing of Fig. 1;
Fig. 4 is the Y portion enlarged drawing of Fig. 2.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, metal anti-static type Powder Recovery filter core of the present utility model, comprise top cover 1 and bottom 2, between top cover 1 and the bottom 2 support cages 3 is installed, between top cover 1 and the bottom 2, the outer end of support cages 3 is arranged with accordion polyester fiber filter screen 4, the outer surface of accordion polyester fiber filter screen 4 has layer of metal conductive layer 5.This conductive layer 5 can be aluminium film, copper film, nickel film or other metal conductive film.
And as preferred version, described metal conducting layer 5 covers aluminium film, its thickness such as 0.01mm for thickness within 0.005mm～0.03mm scope.
Claims (2)
1, metal anti-static type Powder Recovery filter core, comprise top cover (1) and bottom (2), between top cover (1) and the bottom (2) support cages (3) is installed, between top cover (1) and the bottom (2), the outer end of support cages (3) is arranged with accordion polyester fiber filter screen (4), it is characterized in that: the outer surface of accordion polyester fiber filter screen (4) has layer of metal conductive layer (5).
2, metal anti-static type Powder Recovery filter core according to claim 1 is characterized in that: described metal conducting layer (5) covers the aluminium film for thickness within 0.005mm～0.03mm scope.
