One end opening of the leak-off pipe is fixedly mounted on the filtration pipe and communicated with the filtration pipe in a sealed mode, the other end opening of the leak-off pipe is a leak-off pipe orifice, and the height of the pipe orifice of the leak-off pipe communicated with the filtration pipe is higher than that of the filter screen arranged in the filtration pipe body. The rainwater filtration device is simple in structure, fine in filtration effect, not easy to block, convenient for cleaning, low in construction cost and wide in application range.
Description
Technical field
The utility model relates to a kind of rainwater recycle device, particularly a kind of rainwater filtering device.
Background technology
China's water resources ownership per capita is about 1/4 of world's per capita share, adds the spatial and temporal distributions inequality, and the imbalance between supply and demand of water resource is particularly outstanding.Along with development, the increase of population, the quickening of urbanization process of Chinese national economy, the imbalance between supply and demand of following water resource will be more sharp-pointed.The shortage of water resources in many cities has become influences the bottleneck that can its economy sustainable development.In order to alleviate water resources crisis, develop, utilize rainwater resource to become the important channel that many countries and regions solve the water crisis, be subjected to common concern.Many cities in countries such as the U.S., Japan, Germany, India and China Taiwan have all begun roof, platform rainwater are collected, are used to wash lavatory, lawn greening, construction manmade landscape, artificial landscape etc.Rainwater plays crucial effect as a kind of resource of preciousness in the municipal water circulatory system and basin water environmental system.But contain branch, leaf and various foreign material in the unfiltered rainwater of collecting,, can produce problems such as environmental pollution, need the foreign material in the further filtering rainwater, could utilize better if directly utilize.
There is following shortcoming in existing rainwater filtering device: 1, the filter plant structure is too complicated, manufacturing cost is high, is unfavorable for wide popularization and application.2, filtration is coarse, needs other power support.3, be inconvenient to safeguard cleaning, cause foreign material such as leaf or branch to block for a long time in screen pipe easily, and then the deterioration of efficiency that causes dmp filter to collect.
Summary of the invention
The purpose of this utility model is to improve the defective of prior art, and a kind of simple in structure, low cost of manufacture, good filtration effect, cleaning are convenient, the rainwater filtering device of applied range and provide.
For achieving the above object, the utility model adopts following technical proposals:
A kind of rainwater filtering device, described filter comprises screen pipe and leak-off pipe; Described screen pipe is a straight tube, and its upper orifice is a water inlet, and its lower nozzle is a delivery port, and is provided with screen pack in this screen pipe body; Described leak-off pipe one port is packed on the screen pipe, and seals connection mutually with described screen pipe, and the another port is the earial drainage mouth of pipe; The mouth of pipe height that described leak-off pipe is connected with screen pipe is higher than set screen pack height in the described screen pipe body.
Further, the pipe diameter at the interior set screen pack place of described screen pipe is greater than the pipe diameter of described screen pipe water inlet.
Further, described screen pipe inboard wall of tube body is provided with holder, and described screen pack removably mates and is installed on the described holder.
Further, described screen pack is circular arcuation concaver, and being installed in the described screen pipe of making progress of convex surface.
Further, described leak-off pipe is " ┓ " shape pipe, and it comprises horizontal body and vertical body, and the length of described horizontal body is less than the length of vertical body.
Further, described vertical body is provided with valve.
Further, described screen pack comprises one deck screen pack at least.
Operation principle of the present utility model is: rainwater enters screen pipe from the water inlet of screen pipe, and after the screen pack of flowing through filtered, from the delivery port outflow of screen pipe, the foreign material in the rainwater were retained on the screen pack.Because of the position of described screen pack in screen pipe is lower than the nozzle position that leak-off pipe is connected with screen pipe, so the top at screen pack can form certain thickness water layer, when filtering for water to greatest extent, also the floating thing in the rainwater can be rushed in leak-off pipe, this water layer also can produce the disturbance current under the percussion of inlet pipe rainwater, the graininess foreign material that filter out are poured leak-off pipe discharge.When the foreign material on the screen pack influence filter effect too much, desirablely go out screen pack, utilize once more after removing foreign material.The length of the vertical body of described leak-off pipe is longer, is in order to store a certain amount of foreign material, when foreign material are too many, can open the valve on the vertical body of leak-off pipe, removes foreign material and is beneficial to earial drainage.
The utility model compared with prior art has following actively useful effect:
1, simple in structure, good filtration effect, cost are low, can make the filter of different tube diameters according to the size of filtration rainwater flow.
2, leak-off pipe comprises horizontal body and vertical body, and vertically the part of body is longer, the foreign material in the later stage dmp filter that can remain in a standstill.
3, the mouth of pipe height that is connected with screen pipe of leak-off pipe is higher than set screen pack height in the screen pipe body, makes rainwater when flowing through herein, forms the certain thickness water surface, to greatest extent rainwater is filtered, and floating thing can be rushed in leak-off pipe; And under the gravity effect of rainwater, can produce the disturbance current, the graininess foreign material that the mistake screen pack can be leached are brought leak-off pipe into and are discharged.
4, have good filtration effect, the difficult characteristics such as obstruction, cleaning convenience, applied range that produce.
