Abstract
The utility model discloses spiral-flow type flow guiding type end cap on the outside of a kind of filter core, including end cap, the end cap top end face is provided with orientation post, the orientation capital end face center sets fluted, and groove inner chamber bottom center is provided with through hole, and the through hole runs through end cap central inner chamber, and extend to end cap bottom face, the through hole bottom face is radially fixed to be provided with a meter font position-limited rack, and the end cap sidewalls are provided with guide vane, and the guide vane is provided with gradient with end cap upper and lower end face.The utility model is spiral-flow type flow guiding type end cap on the outside of filter core, after raw water is through end cap outboard diversion blade water conservancy diversion, water flow rotary downwards, washes away filter core outside, can prevent the dirt deposition being trapped on the outside of filter core, reduce the degree that filter core is blocked, filter core is set to keep normal water flux for a long time, through the raw water of guiding gutter blade flow, tangential from filter core enters filter core, the time of contact of raw water and filter core can so be extended, clean-up effect of the filter core to raw water is improved.
Description
Technical field
The utility model is related to end cover of filter element applied technical field, spiral-flow type flow guiding type end on the outside of specially a kind of filter core
Lid.
Background technology
Present filter element filtering realizes cleaning function, effect is significant and simple structure, but filter core is used through long-time, can be gone out
The phenomenon that existing pollutant is blocked, is difficult to reach effect of cleaning filtering, existing filter core can't delay raw water enter filter core when
Between, it is impossible to during enough thoroughly cleaning filter core intracavity sidewalls, residual contaminants are easily accumulated, so a kind of filter core outside of design production here
Spiral-flow type flow guiding type end cap, for being easy to improve the efficiency of cleaning filtering.
Utility model content
The purpose of this utility model is to provide spiral-flow type flow guiding type end cap on the outside of a kind of filter core, to solve above-mentioned background skill
The problem proposed in art.
To achieve the above object, the utility model provides following technical scheme：Spiral-flow type flow guiding type end on the outside of a kind of filter core
Lid, including end cap, the end cap top end face are provided with orientation post, and the orientation capital end face center sets fluted, described recessed
Groove inner chamber bottom center is provided with through hole, and the through hole runs through end cap central inner chamber, and extends to end cap bottom face, the through hole
Bottom face is radially fixed to be provided with a meter font position-limited rack, and the end cap sidewalls are provided with guide vane, and are provided with some groups, institute
State guide vane and end cap upper and lower end face is provided with gradient.
Preferably, the guide vane uniform pitch distribution.
Preferably, the through hole inner chamber is socketed with filter core, and the filter core is carbon-point.
Compared with prior art, the beneficial effects of the utility model are：The utility model is spiral-flow type water conservancy diversion on the outside of filter core
Type end cap, after raw water is through end cap outboard diversion blade water conservancy diversion, water flow rotary downwards, washes away filter core outside, can prevent from being cut
The dirt deposition for staying reduces the degree that filter core is blocked on the outside of filter core, filter core is kept normal water flux for a long time, through water conservancy diversion
The raw water of groove blade flow, tangential from filter core enters filter core, can so extend the time of contact of raw water and filter core, improves filter core
It is simple and practical to the clean-up effect of raw water.
Brief description of the drawings
Fig. 1 is the utility model agent structure schematic diagram；
Fig. 2 is the utility model end cap bottom face structural representation；
Fig. 3 is the utility model top view.
In figure：1 orientation post, 2 grooves, 3 through holes, 4 end caps, 5 guide vanes, 6 meters of font position-limited racks, 7 filter cores.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：Spiral-flow type flow guiding type end cap on the outside of a kind of filter core,
Including end cap 4, the top end face of the end cap 4 is provided with orientation post 1, and the orientation top end face of post 1 centrally disposed fluted 2 is described
The inner chamber bottom center of groove 2 is provided with through hole 3, and the through hole 3 runs through the central lumen of end cap 4, and extends to the bottom face of end cap 4,
The bottom face of the through hole 3 is radially fixed to be provided with a meter font position-limited rack 6, and the side wall of the end cap 4 is provided with guide vane 5, described
Guide vane 5 and the upper and lower end face of end cap 4 are provided with gradient, and water flow rotary downwards, washes away filter core outside, can extend raw water and
The time of contact of filter core, clean-up effect of the filter core to raw water is improved, the guide vane 5 is provided with some groups, and uniform pitch
Distribution, the inner chamber of the through hole 3 is socketed with filter core 7, and the filter core 7 is carbon-point.
Operation principle：After raw water is through the water conservancy diversion of 4 outboard diversion blade of end cap 5, water flow rotary downwards, washes away the outside of filter core 7,
The dirt deposition being trapped can be prevented in the outside of filter core 7, the degree that filter core 7 is blocked is reduced, filter core 7 is kept normal for a long time
Water flux, through the raw water that guide vane 5 flows, tangential from filter core 7 enters filter core 7, can so extend raw water and filter core 7
Time of contact, improve clean-up effect of the filter core 7 to raw water.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out various changes in the case where principle of the present utility model and spirit is not departed from, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
