Abstract
The utility model relates to a filter capable of alleviating the blockage of a filter screen. The filter comprises a filter shell, a liquid inlet, an liquid outlet, a residue collecting chamber, a drain outlet, a filter screen and a high-pressure washing spray nozzle, wherein the liquid inlet and the liquid outlet are formed in two sides of the filter shell and is positioned in the same axis; the residue collecting chamber and the drain outlet are formed below the filter shell; the filter screen is arranged in front of the liquid outlet; the high-pressure washing spray nozzle matched with the filter screen in shape is arranged on the outer side of the filter screen. The filter is characterized in that a dispersing device which can be used for dispersing liquid at an inlet of the filter is arranged between the inlet of the filter and the filter screen, so that the flow velocity of the liquid is reduced, the contact area between the liquid and the filter screen is increased, and the phenomenon that the filter screen is locally blocked as the liquid directly impacts the filter screen is avoided.
Description
Technical field
The utility model relates to a kind of self-cleaning filter.
Background technology
Existing self-cleaning filter, liquid entrance is in the situation that coaxial, because the liquid of large flow enters filter housings from import, directly impacts filter screen, causes filter screen to damage and the filter net jam frequency rises, and causes cleaning more frequent, and efficiency is lower.
Summary of the invention
For solving the technical problem that current strainer screen is fragile, stop up, the utility model provides a kind of filter that alleviates filter net jam.
Technical solution of the present utility model is as follows:
A kind of filter that alleviates filter net jam, comprise filter housings, be arranged on the filter housings both sides and be positioned at liquid-inlet and the liquid outlet on same axis, be positioned at filter housings below slag trapping chamber and sewage draining exit, be arranged on liquid outlet the place ahead screen pack, be arranged on the high-pressure wash nozzle that the screen pack outside and screen pack shape are complementary, its special character is: but also comprise the diffusing device of the dispersing filter entrance liquid be arranged between liquid-inlet and screen pack.
Above-mentioned diffusing device be shaped as taper, the vertex of a cone is towards liquid-inlet, the cone bottom surface is to screen pack.
Above-mentioned diffusing device to be shaped as bar tabular.
Above-mentioned screen pack be shaped as half round post.
The beneficial effects of the utility model:
The utility model can alleviate the filter of filter net jam, but by being arranged on the diffusing device of the dispersing filter entrance liquid between filter inlet and screen pack, reduced flow rate of liquid, liquid and filter screen contact area are increased, prevent that liquid from flowing direct impact filtration net and causing the local phenomenon of stopping up of screen pack.
The accompanying drawing explanation
The front section view that Fig. 1 is filter;
The partial side view that Fig. 2 is filter;
Fig. 3 is the top view after filter removes lid;
Wherein: the 1-filter housings, the 2-fluid inlet, the 3-fluid issuing, the 4-screen pack, 5-diffusing device, 6-supports, 7-slag-drip opening, 8-slag trapping chamber, 9-sewage draining exit, 10-high-pressure wash nozzle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of filter that alleviates filter net jam, comprise filter housings 1, be arranged on the filter housings both sides and be positioned at liquid-inlet on same axis 2 and liquid outlet 3, the slag trapping chamber 8, collection cinder notch 7 that is positioned at the filter housings below and sewage draining exit 9, be arranged on liquid outlet the place ahead half-cylindrical screen pack, be arranged on the high-pressure wash nozzle 10 that the screen pack outside and screen pack shape are complementary.
The filter of this structure, because the liquid of large flow enters filter housings from import, directly impact filter screen, causes filter screen to damage and the filter net jam frequency rises, and causes cleaning more frequent, and efficiency is lower; Because the distribution of washer jet is discontinuous, the washer jet aperture is less, easily results in blockage, and can not comprehensively clean screen pack, is difficult to the cleaning performance that reaches desirable simultaneously.
For this reason, but the interpolation of the utility model between filter inlet and screen pack the diffusing device of dispersing filter entrance liquid.When liquid flows through the diffusing device, the flow velocity of liquid reduces, and liquid increases with the filter screen contact area, thereby prevents liquid from flowing direct impact filtration net and cause the phenomenon of the local obstruction of screen pack.
The shape of diffusing device can be taper, and the vertex of a cone is towards filter inlet, and the cone bottom surface, to screen pack, can be also the batten shape, screen pack be shaped as half round post.
Claims (4)
1. the filter that can alleviate filter net jam, comprise filter housings, be arranged on the filter housings both sides and be positioned at liquid-inlet and the liquid outlet on same axis, be positioned at filter housings below slag trapping chamber and sewage draining exit, be arranged on liquid outlet the place ahead screen pack, be arranged on the high-pressure wash nozzle that the screen pack outside and screen pack shape are complementary, it is characterized in that: but also comprise the diffusing device of the dispersing filter entrance liquid be arranged between liquid-inlet and screen pack.
2. the filter that alleviates filter net jam according to claim 1 is characterized in that: described diffusing device be shaped as taper, the vertex of a cone is towards liquid-inlet, the cone bottom surface is to screen pack.
3. the filter that alleviates filter net jam according to claim 1 is characterized in that: described diffusing device to be shaped as bar tabular.
4. according to claim 1 or the 2 or 3 described filters that alleviate filter net jam, it is characterized in that: described screen pack be shaped as half round post.
