Abstract
The utility model discloses a novel filter cap, and solves the problem that slits of the existing filter cap are difficult to clean when being blocked by impurities. The novel filter cap comprises a filter cap head, a supporting seat positioned at the bottom of the filter cap head, and a filter rod extending into the filter cap head from the supporting seat, wherein a buried sleeve is arranged on the outer side of the filter rod; and elongated thin slits are uniformly formed in the arc surface of the filter cap head. The novel filter cap is characterized in that the filter cap head and the filter rod have split type structures and are in threaded connection with each other; a filter net is also arranged on the inner side of the filter cap head; and the filter net is attached to the inner wall of the filter cap head. When the slits of the filter cap is blocked by the impurities, the impurities can be cleared away by opening the filter cap head and taking out the inner filter net; and the whole filter cap is not required to be taken out, thereby being very convenient.
Description
Technical field
The utility model relates to a kind of water treatment parts, is specifically related to a kind of novel filter cap.
Background technology
Evenly have the rectangular finedraw of meticulous processing on the filter cap cambered surface, can prevent spilling of filtrate, can guarantee distribution and even water distribution again.The filter bar is that a plastic tube top has an aperture, near the bottom two air inlet bar seams are arranged, after compressed air enters space below the filter plate, form air layer lentamente, and thickening gradually, water below the air layer constantly descends, and when the water surface was down to the rectangular air inlet bar seam place of filter bar bottom, at this moment air began to go into to filter bar by bar seam orifice flow.When the air mass flow that flows to equates with the flow that flows away through filter cap slit flow, the water surface just stops to descend, be stabilized on the certain position, the air that enters leads to the eject slot of filter cap in filter material layer through the rising of filter bar, because the crosswise jet of a plurality of filters evenly distributes, and reaches good backwash effect.
But such filter cap, the impurity in water are more for a long time, and in the process of carrying out backwash, the slit of filter cap is easy to and can be stopped up by impurity, does not just reach the effect of backwash.And existing filter cap all is that integral molded plastic forms, and is if whole the taking out from the filter plate layer of filter cap cleared up, also pretty troublesome when refilling back.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of novel filter cap, has mainly solved and has cleared up pretty troublesome problem when existing filter cap slit is stopped up by impurity.
The technical scheme that the utility model adopts is: a kind of novel filter cap, comprise filter cap head, be positioned at the supporting seat of filtering cap head bottom, and stretch into filter bar the filter cap head from supporting seat, the described filter bar outside also is provided with service sleeve, evenly have rectangular finedraw on the described filter cap head cambered surface, described filter cap head is split-type structural with the filter bar, and both are solidly connected by screw thread; Described filter cap head inboard also is provided with screen pack, and described screen pack is fitted on the inwall of filter cap head.
Described filter bar downside is provided with two air inlet bar seams, also is provided with screen pack in the described air inlet bar seam.
The diameter of described supporting seat is greater than the diameter of filter cap head.
The beneficial effects of the utility model are: owing to take technique scheme, when the slit of filter cap is stopped up by impurity, only need turn on filter cap head, take out inner screen pack cleaning and get final product, not need whole filter cap is taken out, and very convenient.
Description of drawings
Fig. 1 is cutaway view of the present utility model.
1-filter cap head among the figure, the 2-supporting seat, 3-filters bar, 4-service sleeve, the rectangular finedraw of 5-, 6-screen pack, 7-air inlet bar seam.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1, a kind of novel filter cap, comprise filter cap head 1, be positioned at the supporting seat 2 of filtering cap head 1 bottom, and stretch into filter bar 3 the filter cap head 1 from supporting seat 2, described filter bar 3 outsides also are provided with service sleeve 4, evenly have rectangular finedraw 5 on described filter cap head 1 cambered surface, described filter cap head 1 is split-type structural with filter bar 3, and both are solidly connected by screw thread; Described filter cap head 1 inboard also is provided with screen pack 6, and described screen pack 6 is fitted on the inwall of filter cap head 1.Described filter bar 3 downsides are provided with two air inlet bar seams 7, also are provided with screen pack 6 in the described air inlet bar seam 7.
Like this, when the slit 5 of filter cap is stopped up by impurity, only need turn on filter cap head 1, take out 6 cleanings of inner screen pack and get final product, not need whole filter cap is taken out, very convenient.
The diameter of described supporting seat 2 is greater than the diameter of filter cap head 1, when whole filter cap is nuzzled in the filter in advance, is as the criterion with supporting seat 2, and supporting seat exposes filter more than 2, conveniently turn on filter cap head 1.
Every technical staff's notice: though the utility model describes according to the above-mentioned specific embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
