Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain The utility model, is not used to limit the utility model.

As shown in Figures 1 to 4, embodiment of the present utility model provides a kind of suspension type catch-basin filter 100, bag Include：

Filter frame 11, it includes the filter frame body 111 of end opening, the upper open end by filter frame body 111 up and down Outer rim stretch out the hanger flange 112 in a ring to be formed, be symmetricly set in two of upper surface of the hanger flange 112 Handle 113 and be coated on the hanger flange 112 lateral surface flexible liner 114；

Filter assemblies 12, it includes the upper filter screen 121 of the upper open end located at the filter frame body 111, located at described The lower filter screen 122 of the lower open end of filter frame body 111, the filtrate 123 between lower filter screen 122 and the upper filter screen 121, And it is coated on the filter cloth 124 of the outer surface of filtrate 123；

Overflow pipe 13, it is coaxially disposed with the filter frame body 111 and runs through the filter assemblies 12, and distal process thereon For the upper filter screen 121.

It is specific when setting, due to needing timing to clear up filter 100, therefore filter 100 need regularly from Taken out in catch-basin 200, and for the ease of filter frame 11 is taken out, the cross section of filter frame 11 is necessarily less than catch-basin 200 Gap is necessarily formed between cross section, the i.e. inwall of hanger flange 112 and catch-basin 200, therefore the present embodiment can be in catch-basin 200 Inwall on fixed mount 400 in a ring is set, hanger flange 112, which coordinates, to be placed on fixed mount 400, and hanger flange 112 lower surface coordinates the upper surface for being connected to fixed mount 400, while the lateral surface in hanger flange 112 coats flexible liner 114, the outer rim of the flexible liner 114 can coordinate the inwall pushed against in catch-basin, so as to avoid rainwater without filter assemblies 12 Be directly entered sewer pipe 300, it is ensured that rainwater first by filter assemblies 12 filter after enter back into sewer pipe 300, it is and flexible Pad 114 has certain elastic deformation so that filter 100 easily can be removed and placed into catch-basin, while its The gap between filter 100 and catch-basin 200 can be avoided to block, also allow for filter 100 by catch-basin 200 take out into Row cleaning.Specifically, flexible liner 114 described in the present embodiment is including the sponge core 114a in closed hoop and is coated on the sea The Waterproof leather layer 114b of continuous core 114a outer surface, can avoid sponge core 114a from adsorbing rain by coating Waterproof leather layer 114b Water and corrode, cause its service life shorten.

When the present embodiment is set, the formation of filter frame 11 can match with the shape of catch-basin 200, corresponding filter assemblies 12 formation also with filter frame 11 matches, so as to ensure the removal efficiency of maximized impurity and pollutant, i.e. the present embodiment Filter frame 11 may be configured as the shapes such as circle, rectangle, ellipse, polygon, for the ease of description, the present embodiment is by filter frame 11, which are set to rectangle, is described, and it is not to limitation of the present utility model.Wherein, when filter frame 11 is set to rectangle, Corresponding filter frame body 111, hanger flange 112 and flexible liner 114 are rectangle, i.e. hanger flange 112 and flexible liner 114 be rectangular ring.

By manually taking out filter 100 with certain difficulty, therefore typically can respectively it be hung on by two hooks Filter 100 is taken out on two handles 113, in order to ensure the stability of filter 100 during taking out, the present embodiment Two handles 113 are V-shaped, and two free ends of the handle 113 are all connected to the upper table of the hanger flange 112 Face, the harmony of filter 100 can be improved by being hung on V-type handle 113, be easy to filter 100 being removed and placed into In catch-basin 200.

Because hanger flange 112 is hung on fixed mount 400 for a long time, hanger flange 112 needs to carry filter 100 The impact of overall weight and rainwater, it easily deforms, therefore filter frame 11 described in the present embodiment also includes multiple rectangular triangles The reinforcing plate 115 of shape, 115 plates of multiple reinforcements are evenly arranged along the length direction of hanger flange 112, and it is each described plus Two right-angle sides of strong plate 115 are respectively cooperating with being connected to the lower surface and the filter frame body 111 of the hanger flange 112 Outer peripheral face, multiple reinforcing plates 115 can increase the intensity of hanger flange 112, extend its service life.For the ease of reinforcing plate 115 Placement, it is necessary to set on fixed mount 400 with the one-to-one multiple breach of reinforcing plate 115, during placement, reinforcing plate 115 can It is built in breach, it can increase the overall stability placed of filter 100.

When in rainstorm weather, the amount of rainfall into catch-basin 200 is larger, under the stop of filter assemblies 12, filtering dress Put 100 flow velocity be less than catch-basin 200 digging water speed, it is easily caused the upper side ponding of filter 100, and ponding reaches Then sewer pipe 300 can be flowed directly into by overflow pipe 13 after to a certain degree, so as to avoid the internal water accumulation of catch-basin 200 and cause draining Not smooth, road ponding, in order to ensure that overflow pipe 13 has preferable flushing effect, overflow pipe 13 protrudes from the upper filter screen 121 Height be at least 30cm, the present embodiment is preferably arranged to 36cm.In practical application, because the rainwater containing solid impurity is straight Tap into and sewer pipe 300 is easily caused in sewer pipe 300 blocks, and in order to avoid sewer pipe 300 is blocked, the present embodiment institute Stating the filter 100 of suspension type catch-basin 200 also includes the overflow filter screen 14 located at the upper open end of overflow pipe 13, the overflow The mesh aperture of filter screen 14 is at least the main impurity by larger particles of 2cm, i.e. the overflow filter screen 14 and removed, it is to avoid larger particles Impurity enter sewer pipe 300 and cause sewer pipe 300 to block.

Its flow is caused to reduce in order to avoid accumulated impurity on overflow filter screen 14, overflow filter screen 14 can described in the present embodiment The pyramidal structure that cross section is from top to bottom gradually reduced is set to, and its lower end is connected to the upper open end of the overflow pipe 13, The outer peripheral face of the overflow filter screen 14 of pyramidal structure can be washed away when rainwater enters catch-basin 200, it can avoid overflow filter screen 14 Outer peripheral face accumulation solid impurity, and then avoid conical screen from blocking.

The filter 100 of the present embodiment is cleared up after the use by certain time, it is necessary to take out, and cleaning is main It is divided into two aspects, is on the one hand the cleaning of the solid impurity to being accumulated on upper filter screen 121, is on the other hand to the clear of filtrate 123 Reason, because the filtrate 123 of the present embodiment is typically coated with the artificial of metal oxide using activated carbon, perlite, zeolite or surface Filler etc., it preferably can filter and adsorb the pollutant in rainwater, and for the ease of cleaning filtrate 123, described in the present embodiment Upper filter screen 121 is with the filter frame body 111 to be detachably connected, and specific upper filter screen 121 can be placed directly in filter frame body 111 upper open end.

Embodiment of the present utility model described above, does not constitute the restriction to the utility model protection domain. Any various other corresponding changes and deformation made according to technical concept of the present utility model, should be included in this practicality In new scope of the claims.
