Abstract
The utility model relates to a bidirectional filtering core of a filter. The bidirectional filtering core of a filter can be repeatedly used in two directions, and is suitable for being arranged in the shell of an existing running water filter. Water is filled in a filter in one direction, after the bidirectional filtering core of a filter is used for a period of time, suspended substances which are smaller than the pore spaces of a filter plate are silted in the filter plate; the filtering core is taken out and is arranged in the shell in a reverse direction, water enters from the other end, making the suspended substances are exhausted in the reverse direction, and the function of cleaning is played. The inner walls of both ends of a cylinder body 1 have estrades, and the filter plate 3 is of a plane polyporous circular plate; the filter plate is put on the estrade to seal and block off carbon fiber. The filter plate 3 the can also be designed into a shape of a circular estrade with a convex porch, and the porch of the circular estrade is put on the estrade, and the inclined plane of the circular estrade enlarges the filtering area.
Description
The utility model relates to the filter of B01D class, a kind of filter core that can be bi-directional filtered.
Existing various running water filters, its filter core is an end opening, the other end has the cylindrical body of boss, fills NACF in the cylindrical shell, the topped fabric filter screen in two ends, openend adds key drop.The filter core of this structure is housed, filter can only unidirectionally be used, intake by the filter core openend.Leach thing in the water and be deposited on in-core,, filter effect and significantly descend with after a while.Such as, home-use water filter generally uses promptly needs more renew cartridge about half a year, if the service of the later stage of filter factory is not good at, the user can't buy filter core, and filter has also just been scrapped so, causes damage to the user.
The purpose of this utility model provides a kind of dual flow filter filter core that can upgrade for a long time voluntarily, improves the service life of filter core.
This dual flow filter filter core comprises cylindrical shell, filter plate, NACF, it is characterized in that cylindrical shell 1 two ends inwall has platform, and filter plate 3 is plane plectanes that porous material is made, and filter plate 3 is placed on the platform in the cylindrical shell 1, and block firmly is filled in the NACF 2 in the cylindrical shell.
The great advantage of this cylindrical structure filter core is two-wayly to use, and is suitable for being contained in the housing of existing running water filter.From the water inlet of direction, use a period of time after, deposit in plate less than the suspension of filter plate hole, at this moment, take out filter core and clubhaul and install, allow water enter and make the reverse discharge of suspension from the other end, play cleaning action.Also have, porous filter plate 3 adopts powder grain husk grain to sinter into, and quality is better than filter screen, and hole is also littler, adds 3～5mm thickness of upper plate, plays the macrofiltration that stops in charcoal fiber outside.Therefore, this filter core can upgrade muchly voluntarily, has prolonged service life.
Accompanying drawing 1 is the profile of this filter core in filter;
Accompanying drawing 2 is the side view of plane filter plate;
Accompanying drawing 3 is the side view of the platform shape filter utmost point;
This dual flow filter filter core comprises cylindrical shell 1, filter plate 3, NACF 2, it is characterized in that cylindrical shell 1 two ends inwall has platform, filter plate 2 is porous plane plectanes, make by metal or non-metal powder particle sintering, porous material forms the space of uniform 0.05～0.1mm, about 3～the 5mm of thickness of slab places plate 3 on the interior platform, plate 3 edges and tube 1 internal diameter tight fit.
Example 2: described filter plate 3 can also be designed to the truncated cone-shaped of convex edge, sees Fig. 3.The similar inverted flowerpot of truncated cone-shaped has the end, round platform and edge.During assembling, the edge of round platform is placed on the platform, the inclined-plane of round platform has increased the filtration area.
Example 3: this two-way filter core can also utilize the novel filter plate 3 of basis of existing filter core orifice plate and the alternative porous material of filter screen, to reduce cost.
Claims (2)
1, this dual flow filter filter core comprises cylindrical shell, filter plate, NACF, it is characterized in that cylindrical shell (1) two ends inwall has platform, filter plate (3) is the plane plectane that porous material is made, and filter plate (3) is placed on the interior platform of cylindrical shell (1), and block firmly is filled in the NACF (2) in the cylindrical shell.
2, filter element according to claim 1 is characterized in that filter plate (3) can also be designed to truncated cone-shaped, is made up of the less end of diameter, Rotary-table and edge.
