In the filtration apparatus using the filter, especially when a large amount of cutting chips are contained, the filtration efficiency is low and the removal of the cutting chips from the cutting oil is not performed properly, so that the content of foreign matters is high when the cutting oil is reused. There is a problem falling.
In addition, when the filter is composed of a metal mesh net for improved durability, foreign matter is attached to the mesh net when it is used continuously for a long time, so the filtering efficiency is reduced. However, it is inconvenient to prepare and replace another metal mesh net.
The present invention has been made to solve the above problems, an embodiment of the present invention, by detecting the internal and external pressure difference of the filter cartridge composed of a metal mesh network to rotate the filter cartridge, It relates to a metal edge filter device that allows foreign matter adhering to a surface to be removed by a scraper.
According to a preferred embodiment of the present invention, the first space is provided therein, a drain valve for discharging foreign matters is connected to the lower end, one side is provided with an inlet through which cutting oil containing foreign matters is introduced, and the other side is removed. A housing provided with an outlet for discharging the cutting oil; A cylindrical filter cartridge installed axially rotatable in the first space, having a second space formed therein, and having a plurality of filter holes formed therein; And a scraper installed vertically on the outside of the filter cartridge and having an end elastically biased to the surface of the filter cartridge, and rotating the filter cartridge by sensing a differential pressure generated between the first space portion and the second space portion. Provided is a metal edge filter device for detecting a differential pressure and cleaning a filter, wherein a foreign substance on the surface of the filter cartridge is removed by a scraper.
In this case, the filter cartridge may further include an air injection tube installed perpendicular to the inside of the filter cartridge so as to face an end of the scraper, and spraying high pressure air supplied from the outside when the filter cartridge rotates to remove foreign substances on the surface of the filter cartridge. have.
On the other hand, the housing is configured to include a cylindrical lower housing having a first space is formed therein, and an upper housing coupled to the upper end of the lower housing to open and close the first space, the filter cartridge is rotatable in the upper housing Combined.
In addition, the upper housing is provided with a rotating shaft, the upper holder is coupled to the upper end of the filter cartridge, the rotating shaft and the upper holder is coupled by a rotating bracket, the rotation of the filter cartridge is made by the rotation of the rotating shaft.
At this time, the lower end of the filter cartridge is supported by the pedestal, the pedestal is coupled to the upper housing by at least one pedestal support shaft.
In addition, the lower end of the scraper support shaft is coupled to one side of the pedestal, the upper end of the scraper support shaft is coupled to one side of the upper housing, the scraper is coupled to one side of the scraper support shaft, the scraper support shaft is interposed with at least one torsion spring, The end of the scraper is elastically biased to the surface of the filter cartridge.
According to the metal edge filter device for cleaning the filter by detecting the differential pressure according to an embodiment of the present invention, it is possible to continuously remove the foreign matter, such as chips from the cutting oil used, high regeneration efficiency, a large amount within a short time Since it is possible to perform the filtering operation on the coolant, it is excellent in utility as a preliminary filtering means performed before the precise filtering process.
In addition, since the foreign matter adhering to the filter cartridge can be effectively removed during long time use, it is possible to reduce the time and cost required for maintenance and repair, and to maintain uniform filtering performance.
