Abstract
The utility model relates to a filtering element. The outer margin of a lower cover of the filtering element is a closed tooth-shaped outline. The outer end of each tooth is fixed with a filtering net. When the filtering element is vibrated, the filtering net can filter dust which is attached on the filtering net, the dust drops out of the space between the teeth of the lower cover, the filtering net can not be clogged, and the filtering net can be conveniently recycled. The utility model provides the filtering element, and when the filtering element is vibrated, and powder dust on the filtering net drops out along a corrugation slot, the powder dust can not be blocked by the lower cover at the lower end.
Description
[technical field] the utility model belonged to filter core.
The filter core excessively that [background technology] is present, with filter material be folded into the accordion filter screen be fixed on discoid lower cover and on cover and steel mesh support the cage outer surface, start filter, in the spray booth air, be mingled with the dust that will filter through the screen pack filtering after attached to filter screen on, the vibration filtering core makes attached to the dust on the filter screen and drops, in order to avoid the obstruction filter screen also is convenient to reclaim.But the dust of shaking off from the accordion ditch of filter screen is stopped and can not drop by the discoid lower cover of lower end, causes the strainer filtering effect low.Be desirable to provide a kind of filter core excessively that dust on the filter screen is not stopped by the lower cover of lower end in mistake filter core vibration processes when the fold ditch drops.
[summary of the invention] the utility model will overcome above-mentioned shortcoming, and a kind of filter core excessively that dust on the filter screen is not stopped by the lower cover of lower end when the fold ditch drops in mistake filter core vibration processes is provided.
The technical scheme that adopts is: a kind of filter core of crossing, comprise loam cake, lower cover, support cage and filter screen, and it is characterized in that: the outer rim of lower cover is the tooth-like wheel profile of sealing, and the outer end of each tooth is the accordion filter screen fixedly.
Adopt this scheme, during the vibration filtering core, after the screen pack filtering attached to the dust on the filter screen along the fold ditch, and drop by the backlash of lower cover, can not stop up filter screen.Improved the strainer filtering effect.A kind of filter core excessively that dust on the filter screen is not stopped by the lower cover of lower end when the fold ditch drops in mistake filter core vibration processes is provided.
