Description

The dmp filter device
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of dmp filter device that is used for rainwater is collected utilization.
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.
China utility model patent 200720001182.X discloses a kind of rainwater filtering device, and it comprises socket pipe on, it comprise water receiving pipe, on overlap base and outlet part; Socket pipe once, it comprises outlet pipe and the base of trapping; And a filtering ring, it is the hollow and annular body, and the cover base of going up of top and last socket pipe combines, and the base of trapping of bottom and following socket pipe combines, and is provided with the cone filter in the stage casing, and it is connected with distributive pipe and bores.Its employing cone filter realization foreign material separates with water purification, and adopts split-type structural, reaches the effect of convenient for maintaining arrangement.But this structure is still perfect not to the utmost, because it adopts the cone filter, the flow area at filter core place is little, and the place is stopped up easily at filter core, and filter efficiency is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of efficient and not susceptible to plugging dmp filter device.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of dmp filter device, comprise water inlet and delivery port, the below of described water inlet is provided with overflow launder, the below of overflow launder is provided with clear water tanks, and described delivery port is arranged on the clear water tanks, and the sidewall of clear water tanks is made of screen pack, bottom from the upper edge of overflow launder to clear water tanks is provided with many horizontal filtration grizzly bars, and described screen pack is positioned at the inboard of filtering grizzly bar.
Preferably, also comprise two end plates, described water inlet and delivery port are arranged on the end plate, and described overflow launder, clear water tanks, filtration grizzly bar and screen pack all are connected between the two end plates.
Further, described water inlet has two, and described delivery port is one.
Further, the both sides of described overflow launder are equipped with the filtration grizzly bar.
Further, the both sides of described clear water tanks are equipped with screen pack.
Further, described clear water tanks is surrounded by the screen pack of a base plate, both sides and the end plate at two ends.
Preferably, the filtering surface that is made of the outer surface that filters grizzly bar is a smooth curved surface.
The beneficial effects of the utility model are: adopt the combination of filtering grizzly bar and screen pack, can realize the twice filtration, filter effect is better.Filtering grizzly bar can be with bigger foreign material filterings such as branch, leaves, and the filtering surface that is made of the outer surface that filters grizzly bar is smooth curved surface, and foreign material can successfully be washed away along current, can not stop up.Bigger material by filtering after, can guarantee that also internal screen can not stop up.Particularly importantly, filtration grizzly bar in the utility model and screen pack can be arranged on the both sides of device, are provided with along its length, and very big filter area is arranged, and can handle the filter efficiency height to big flow.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the perspective view of the utility model dmp filter device.
Fig. 2 is the cross sectional representation of the utility model dmp filter device.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model dmp filter device comprises two end plates 1, and a water inlet 3 respectively is set on the two end plates 1, and wherein an end plate 1 is provided with delivery port 5.The two ends of overflow launder 2 are fixedly connected on the two end plates 1, form the cell body that opening makes progress, and are positioned at the below of water inlet 3, can accept the water to be filtered that flows into from water inlet 3.
The below of overflow launder 2 is provided with clear water tanks 7, and clear water tanks 7 is surrounded by the screen pack 6 of a base plate 8, both sides and the end plate 1 at two ends, and wherein screen pack 6 constitutes clear water tanks 7 side walls, and the two ends of screen pack 6 and end plate 1 join, and delivery port 5 communicates with clear water tanks 7.
In the both sides of overflow launder 2, the bottom from the upper edge of overflow launder 2 to clear water tanks 7 is provided with many horizontal filtration grizzly bars 4, filters grizzly bar 4 and is connected abreast between the two end plates 1.Filtration grizzly bar 4 covers on the outside of screen pack 6, in the vertical direction filters grizzly bar 4 and arranges according to trend from top to bottom, filtering grizzly bar 4 in the horizontal direction arranges according to trend from inside to outside, and in each side of overflow launder 2, the filtering surface that is made of the outer surface that filters grizzly bar 4 is a smooth curved surface.
The following describes operation principle of the present utility model.
Current enter overflow launder 2 from water inlet 3, and the both sides from overflow launder 2 overflow then, flow downward along filtering grizzly bar 4, and in this process, a part of water is isolated in the outside of filtering grizzly bar 4 together with bigger foreign material, drains as sewage; Another part water sees through and filters grizzly bar 4, drops on the screen pack 6, and the mesh size 0.55mm of screen pack 6 enters clear water tanks 7 from screen pack 6 again, and the water purification that filters through twice flows out from delivery port 5 like this, can be stored or utilize.
Filter grizzly bar 4 owing to arrange, and form smooth curved surface, therefore, can not stop up along current; Screen pack 6 also is obliquely installed, and is filtered the impurity that net 6 stops, also can be fallen by current scour, flow away with sewage, so the screen pack 6 of internal layer can not stop up yet.
