Description

A kind of dmp filter purifier
Technical field
The utility model relates to a kind of filtering and purifying, is used for filtration, purification and collects in particularly a kind of sponge urban construction The device of rainwater.
Background technology
The thinking that conventional urban construction solves rainwater emission problem is that fast row is put soon, is collected its draining municipal administration by ground rainwater mouth Storm sewer system, is finally drained to natural water area.This processing method does not consider the collection recycling of rainwater, wastes Natural resources, and be not provided with regulating and storing and purification facility, be involved in by rainwater under heavy showers environment the rubbish of pipe-line system with miscellaneous Thing not only easy blocking pipeline, can cause environmental pollution to natural water area equally.
In order to solve upper problem, country proposes " sponge city " this concept, the i.e. rain for modern city design Flood management concept, allows urban infrastructure can adapt to environmental change, elastic can tackle the impact that rainwater brings, in rainfall When collect rainwater, be detained rainwater, purifying rainwater, savings rainwater, infiltration rainwater, when needed again will storage rainwater release Utilize;
Before rainwater enters final collection container savings, it is necessary to filtration, purification is carried out to rainwater;Net at the conventional dmp filter of tradition In gasifying device, most material for core is that one or more materials are blended in a container, and water inlet introduces from filter core top, The weight utilizing water filters downwards, and this filter type has the disadvantage that: (1) filtering material is single or multiple material to mix be one Body, is unfavorable for the suspended particulate step filtering purifying in rainwater, and is unfavorable for exchange and the maintenance of later stage filter core.(2) rain Water filters from the top down, and the impurity so filtering out can be stayed on filter core, and the time one, these impurities accumulations long were too much, will be dirty Dye and blocking filter core, cause filter element filtering efficiency to reduce, and the water quality simultaneously filtering also cannot ensure, serious even can block Filter element;(3), after traditional filter element uses a period of time, need to be rinsed filter core with clear water, attached to remove Impurity above, serious is accomplished by material for core integral replacing, so can waste substantial amounts of clear water, also can additionally increase Add maintenance cost, increase workman's workload.
Utility model content
The purpose of this utility model is: provides and a kind of realizes that the efficient depth-type filtration of rainwater and impurity screening clear up discharge automatically Filtering and purifying, is realized by following technical proposals:
A kind of dmp filter purifier, described device is double-wall structure, and the chamber that internal chamber wall is surrounded is filter chamber, mistake Being provided with filter element in filter chamber, filter element is provided above collection port, and the chamber between internal chamber wall and outer chamber wall is drainage lumens, Being provided with through hole bottom internal chamber wall, filter chamber is through with drainage lumens, and outer chamber wall is provided above through with drainage lumens entering water Mouthful, bottom of device is provided with the sewage draining exit through with filter chamber.
The utility model uses reverse filter design, is arranged by said structure, after current enter drainage lumens from water inlet, Enter savings below filter chamber by through hole, when liquid level savings is to after to a certain degree, is entered by filter element from below and filter Above chamber, then enter rain water collecting system by collection port.
Alternatively, described water inlet area is more than sewage draining exit area.After current enter from water inlet, will not be all rapid Entering sewage draining exit, undischarged rainwater enters collection port owing to liquid level pressure acts through filter element after putting aside in filter chamber, Realize reverse filtration.
Alternatively, body bottom portion is provided with the valving for control of sewage disposal mouth opening and closing.
Alternatively, described valving is ball-cock assembly.
After liquid level proceeds to certain phase, sewage draining exit is closed by ball-cock assembly, improves liquid level savings and the rate of filtration further.
Alternatively, described ball-cock assembly includes ball float, lever and bulb stopper, and bulb stopper is provided with leakage mouth.
Alternatively, described filter element includes framework and filtering module, and lower portion is provided with several layers and crosses filter grid, filters mould Block was arranged in filter grid, was provided with filtering core in filtering module, and size, the size of filtering module are all equal, mutually it Between replaceable.
Alternatively, described filtering core is quartz sand, activated carbon, filter screen or filter cloth.
Alternatively, it is provided with three layer filtration lattice in described framework, by arrange in dmp filter direction, first floor filtering module Filtering core is the quartz sand of 50 mesh, and intermediate layer is 100 mesh quartz sands, and tail layer is activated carbon.
Filter element uses same size, the filtering module of size, can replace at any time with each other, needs safeguarding or adjusting to filter When asking, filtering module is extracted out in crossing filter grid and replace;Filtering core uses various material, can be at any time according to filtration needs Change;Impurity in rainwater and large-scale particulate matter are filtered by the first floor with middle level, and fine particle thing is adsorbed by tail layer activated carbon, with Reach to purify purpose.As existed between filter element and internal chamber wall, gap is installed, can be at frame edge and institute's installation site seam crossing Add sealant or diaphragm seal, it is to avoid do not filter rainwater and reveal from seam crossing.
Alternatively, described device top is provided with access hole, and attendant can enter inside device to filter element and ball float Valve is safeguarded, convenient and reliable.
Workflow of the present utility model is:
1. rainwater flows into from water inlet through drainage lumens, and after filtering the last time, the impurity of deposition is gone out from sewage draining exit, due to blowdown Open area is less than water inlet, and therefore rainwater is put aside in filter chamber and drainage lumens;
2. after liquid level puts aside certain position, sewage draining exit is closed by ball-cock assembly, improves liquid level savings speed further;
3., under hydraulic action, rainwater enters above filter chamber by filter element, by the rainwater after filtration, purification by collecting Mouth enters rainwater-collecting pipeline;
4. after rainfall stops, water inlet stops water inlet, and leakage mouth from ball-cock assembly bulb stopper for the rainwater of the interior savings of device is slow Discharging, the impurity screening that the water level decreasing in filter chamber will be attached on filtering module is taken out of, in the bottom of filter chamber Deposition;
5. after liquid level drops to certain phase, ball-cock assembly is opened, and residue rainwater is discharged from sewage draining exit, takes away part mistake simultaneously The impurity of filter deposition, device resets, and waits and filtering next time.
In sum, the beneficial effects of the utility model:
1. parts carry out modularized design, and filtering module external dimensions is identical, every kind of module filling one material for core, Tiny suspended particulate in rainwater together, can be carried out classified filtering by the block combiner of the different material for core of filling Purify, promote filter effect, can by new module exchange when filter core need to keep in repair replacing simultaneously, safeguard very simple Single;
2. using counter-current to filter, the impurity so filtering out stays the bottom of filtering module, at the end of filter process, inverse The rainwater of stream takes filtering module out of the impurity being attached to module bottom under gravity;
3. utilize the sewage draining exit that bottom of device arranges and ball-cock assembly can realize automatically cleaning and discharge to impurity screening.
