A kind of rainwater-collecting filter

Technical field

The utility model relates to a kind of rainwater-collecting filter.

Background technology

Due to the scarcity of water resource, the collection recycling of rainwater becomes the project of various countries' development and application, the collection of rainwater, storage and filtration are the main investigative techniques of rainwater recycling, the technology of current rainwater recycling mainly comprises roof rain water collecting recycling, park green land infiltration rainwater treatment, rainwater integrated treatment and rainwater advanced treating, the water again utilized is mainly used in flushing the toilet, carwash, air-conditioning, the aspect such as irrigation and view, not only can obtain good economic benefit, and using water wisely.

But at present, rainwater-collecting filtration system exists following shortcoming: 1, filtration relative complex, and manufacturing cost is high, be unfavorable for promoting; 2, the other power support of needs is filtered; 3, be inconvenient to safeguard cleaning, cause the foreign material such as leaf branch to be stuck in for a long time in filter pipe, and then the deterioration of efficiency causing rainwater-collecting to filter.

Utility model content

The utility model solves above-mentioned technical problem, provides a kind of rainwater-collecting filter.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of rainwater-collecting filter, comprise and filter tank body and filter chipware, filter tank body and be provided with water inlet and delivery port, it is interior and coaxial with it that described filtration chipware is placed in filtration tank body, filter chipware and adopt loop configuration, filtering between the excircle of chipware and inner periphery is filtration beds, the excircle filtering chipware fits with the inner periphery filtering tank body, the inner periphery filtering chipware forms filter chamber, filter the upper end of chipware not higher than water inlet, lower end is not less than delivery port, the bottom surface of filtering chipware is provided with the through hole of discharging foreign material.

Further, the axis of described water inlet and the axis shape of delivery port have angle, and the water entered from water inlet tangentially enters filtration tank body, form eddy flow in the upper surface of filtering chipware.

Further, it is 45 ° that the axis of described water inlet and the axis shape of delivery port have angle.

Further, also comprise a deflector, the axis of described water inlet and the axis being parallel of delivery port, deflector is placed in the upper surface of filtering chipware, extend to the inner periphery filtering chipware from the side of water inlet, the water entered from water inlet forms eddy flow by the upper surface that deflector is filtering chipware.

Further, the upper surface diameter of described filter chamber is greater than lower surface diameter.

Further, described filtration beds comprises metal net layer and multiple layer metal grid.

Adopt the technical solution of the utility model, overall structure is simple, and the low convenient popularization of cost, filters and do not need extra power support, flow into filter chamber downwards, from inside to outside permeation filtration by the eddy flow of water along inwall, simultaneously easy cleaning and maintenance.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As shown in Figure 1, a kind of rainwater-collecting filter, comprise and filter tank body 10 and filter chipware 20, filter tank body 10 and be provided with water inlet 11 and delivery port 12, it is interior and coaxial with it that described filtration chipware 20 is placed in filtration tank body 10, filter chipware 20 and adopt loop configuration, filtering between the excircle of chipware 20 and inner periphery is filtration beds 21, filtration beds 21 comprises metal net layer and multiple layer metal grid, the excircle filtering chipware 20 fits with the inner periphery filtering tank body 10, the inner periphery filtering chipware 20 forms filter chamber 22, the upper surface diameter of filter chamber 22 is greater than lower surface diameter, filter the upper end of chipware 20 not higher than water inlet 11, lower end is not less than delivery port 12, the bottom surface of filtering chipware 20 is provided with the through hole 23 of discharging foreign material.

As shown in Figure 2, filter comprises filtration tank body 10 and filters chipware 20, the axis of water inlet 11 and the axis shape of delivery port 12 have angle, most preferred, it is 45 ° that the axis of water inlet 11 and the axis shape of delivery port 12 have angle, the water entered from water inlet 11 tangentially enters filtration tank body 10, eddy flow is formed in the upper surface of filtering chipware 20, the water forming eddy flow flows into filter chamber 22 along the inner periphery filtering chipware 20, side filtration and infiltration from inside to outside, the water after filtration is flowed out by delivery port 12.

As shown in Figure 3, filter comprises filtration tank body 10, filters chipware 20 and deflector 30, the axis of water inlet 11 and the axis being parallel of delivery port 12, deflector 30 is placed in the upper surface of filtering chipware 20, deflector 30 extends to the inner periphery filtering chipware 20 from the side of water inlet 11, the water entered from water inlet 11 forms eddy flow by the upper surface that deflector 30 is filtering chipware 20, the water forming eddy flow flows into filter chamber 22 along the inner periphery filtering chipware 20, side filtration and infiltration from inside to outside, the water after filtration is flowed out by delivery port 12.

Filter can directly use, also the flow abandoning apparatus can arranged in pairs or groups early stage uses, as shown in Figure 4, rainwater first carries out first time initial filter impurities removal by flow abandoning apparatus, then filter is entered into by water inlet 11, enter filter water and form eddy flow in filtration chipware 20 upper surface, filter chamber 22 is flowed into along the inner peripheral surface filtering chipware 20, the water of filter chamber 22 is by filtration beds 21 side filtration and infiltration from inside to outside, water after filtration is flowed out by delivery port 12, and the residue after filtration is discharged by the through hole 23 filtering chipware 20 bottom surface.
