Abstract
The utility model provides a rainwater filtering sheet comprising two parallel side plates, a plurality of transverse filtering grid bars fixed between the two side plates, and a filtering screen, wherein the outer surface of the filtering grid bars constitutes a filtering surface that is particularly a smooth curved surface; the filtering screen is located on the inner side of the filtering surface; and the filtering screen is inclined downwards towards the filtering surface. Accordingly, the utility model can prevent the rainwater filtering sheet from being blocked.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of filter that is used for dmp filter.
Background technology
Rainwater is a kind of very important freshwater resources, along with the enhancing of people's consciousness of saving water, the collection utilization of rainwater is also quoted day by day people's attention.But the rainwater that collect in the place from the roof etc. can be mingled with foreign material such as a lot of branches, leaf, the foreign material filtering in the rainwater could further need be utilized.
Existing dmp filter sheet adopts the individual layer setting more, easily stops up, and filter efficiency is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of bilayer, not susceptible to plugging dmp filter sheet.
In order to solve the problems of the technologies described above, the dmp filter sheet that the utility model provides, comprise two blocks of parallel side plates, be fixed on many horizontal filtration grizzly bars and a screen pack between two blocks of side plates, the filtering surface that described filtration grizzly bar outer surface constitutes is a smooth curved surface, described screen pack is positioned at the inboard of filtering surface, and described screen pack is tilted to down towards the filtering surface direction.
Preferably, described filtering surface is male type.
Preferably, the first half of described screen pack is vertically placed, and the latter half is tilted to down towards the filtering surface direction.
The beneficial effects of the utility model are: adopt the filtering surface of filtration grizzly bar formation and the combination of screen pack, realize the twice filtration, filter effect is better.Filtering surface can successfully be washed away foreign material along current bigger foreign material filterings such as branch, leaf, can not stop up.Rainwater behind the filtering bigger material passes through screen pack again, filters out less impurity, because of through the rainwater of screen pack filtering bigger material, and be obliquely installed, so screen pack can not stop up yet.
Description of drawings
Fig. 1 is the perspective view of the utility model dmp filter sheet.
Fig. 2 is the position view of filtering surface and screen pack.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1 and Figure 2, dmp filter sheet of the present utility model, comprise two blocks of parallel side plates 3, be fixed on many horizontal filtration grizzly bars and a screen pack 2 between two blocks of side plates 3, the filtering surface 1 that filters grizzly bar outer surface formation is a smooth curved surface, this filtering surface 1 is male type, thereby can be with bigger foreign material filterings such as branch, leaves, foreign material can successfully be washed away along current, can not stop up, screen pack 2 is positioned at the inboard of filtering surface 1, and screen pack 2 is tilted to down towards filtering surface 1 direction.Screen pack 2 is obliquely installed, and is filtered the impurity that net 2 stops, also can be fallen by current scour, flow away with sewage, so the screen pack 2 of internal layer can not stop up yet.
As shown in Figure 1, the first half of screen pack 2 is vertically placed, and the latter half is tilted to down towards filtering surface 1 direction, has increased the filter area of 2 pairs of rainwater of screen pack.
Can also be provided with bolt on the side plate 3 of this dmp filter sheet, be used for this dmp filter sheet is installed to rain collector and rainwater retracting device easily, also can dismantle easily so that clean.
The following describes operation principle of the present utility model.
Rainwater flows downward along filtering the filtering surface 1 that grizzly bar constitutes, and in this process, a part of water is isolated in the outside of filtering surface 1 together with bigger foreign material, drains as sewage; Another part water sees through filtering surface 1, drops on the screen pack 2, purifies by screen pack 2 again, like this through purifying waste water that twice are filtered, can recycle by for example rainwater retracting device.
More than just utility model has been carried out exemplary explanation, specific implementation of the present utility model is not limited thereto.The insubstantial modifications that any employing design of the present utility model and technical scheme are carried out is all within protection domain of the present utility model.
Claims (3)
