Abstract

The utility model relates to a novel cities and towns ground rainwater filters device, including between holding back and between the overflow, the top is equipped with the rain double -edged fine -toothed comb of taking the filter screen between holding back, and the bottom is equipped with horizontal filter between holding back, is equipped with vertical filter between holding back and between the overflow, and the top is equipped with concerte cover plate between the overflow, and the in -connection has rainwater collecting pipe between the overflow. The profitable effect of utility model is: the utility model discloses purify cities and towns ground rainwater quality of water, effectively solved vertical filter and jam and the siltation problem of horizontal filter after operation a period to improve rainwater detergent power and efficiency, the easy operation maintenance of simple structure.

Description

A kind of new cities and towns ground rainwater filter

Technical field

The utility model is related to silt, dust etc. in the hardened ground rainwater of cities and towns and filters and remove, especially a kind of new Cities and towns ground rainwater filter.

Background technology

China's urbanization process of industrialization occurs in that many new situations, new problem, and one side heavy showers causes cities and towns waterlogging Seriously, another aspect town development faces the outstanding problems such as shortage of water resources, water environment degradation again.Town rain is made full use of to delay Solution cities and towns the contradiction of supply and demand for the water resource becomes one of industry common recognition.Cities and towns ground rainwater water quality is affected by all kinds of pollution of area source in cities and towns Larger, the especially activity such as vast Urban Areas road, building, industry and commerce causes downtown areas Particulate Pollution to be in multiple, add Weight trend, therefore the removal to particulate matter becomes the important directions that cities and towns ground rainwater is administered.

A kind of rainwater filtering device of application number 200510026072.4 patent application, the device is tubular structure, tubulose The mid diameter of body is connected between tubular body different structure more than the diameter at both ends by an inwardly projecting platform that intercepts water, A filter water outlet is provided with the platform that intercepts water, the technology is to cities and towns ground rainwater purification filtering unworthiness.Application number 200980160730.5 one rainwater filtering device of patent application, which solves plugged filter and affects filter The problem of filtration yield, but without effectively solving rainwater purification problem.Application number 201210412283.1 provides a kind of suspension type rain Well filter, suspension type catch-basin filter has filtering function, and the device mainly solves mud larger in rainwater Husky debris, and it is not enough to wherein less particulate matter removal ability.

The content of the invention

The utility model will solve the shortcoming of above-mentioned prior art, there is provided a kind of simple structure, improve rainwater purification ability With the new cities and towns ground rainwater filter of efficiency.

The utility model solves the technical scheme that its technical problem is adopted：This new cities and towns ground rainwater filter, Including and between overflow, top is provided with the rain double-edged fine-toothed comb with screen pack between retention, and bottom is provided with transversal filters between retention between retention, cut Between staying and between overflow between be provided with vertical filter, between overflow top be provided with concrete cover, overflow is interior to be connected with rainwater collection Collector.

Preferably, the vertical filter top is provided with spout hole.

Preferably, the transversal filters arrangement elevation is less than vertical filter bottom elevation.

Preferably, the transversal filters and vertical filter adopt replaceable structure.

Utility model has the advantages that：The utility model has purified cities and towns ground rainwater water quality, efficiently solves vertical Filter and the blocking after transversal filters operation a period of time and alluvial problem, so as to improve rainwater purification ability and efficiency, Simple structure is easy to operation maintenance.

Description of the drawings

Fig. 1 is structural representation of the present utility model；

Description of reference numerals：Rain double-edged fine-toothed comb 1, screen pack 2, spout hole 3, concrete cover 4, vertical filter 5 is laterally filtered Device 6, rainwater collection collector 7,8 between retention, 9 between overflow.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in further detail：

Embodiment：As Fig. 1, the screen pack 2 that rain double-edged fine-toothed comb 1 is arranged intercept larger dirt in ground rainwater, rainwater is through filtering Inner space is entered after net 2；Inner space is divided into two parts, and one is between damming 8, and another between overflow 9, the two is by vertical mistake Filter 5 separates.Rainwater between retention 8 first by particulate matter in precipitation adsorption water after its bottom transversal filters 6, when cutting 8 water levels are higher than during 9 water level, rainwater is entered 9 between overflow, then by rainwater Jing after the purification filtering of vertical filter 5 between overflow between staying Collecting pipe 7 is delivered to designated area or memory space.This patent is designed as vertical filter 5 and transversal filters 6 replaceable (assembled) structure, using sandstone filtering material, the top of vertical filter 5 arranges spout hole 3, draining need when meeting especially big rainwater Ask.

In addition to the implementation, the utility model can also have other embodiment.All employing equivalents or equivalent change The technical scheme to be formed is changed, the protection domain of the utility model requirement is all fallen within.
