Description

A kind of U-shaped dmp filter purifier

Technical field

This utility model relates to a kind of filtering and purifying, a kind of U-tube for carrying out dmp filter purification Road device.

Background technology

It is that row's block is put soon that urban construction in the past solves the thinking of rainwater emission problem, is collected by ground rainwater mouth and is arranged Water municipal administration storm sewer system, is finally drained to natural water area.This processing method does not consider the collection recycling of rainwater, wave Take natural resources, and be not provided with regulating and storing and purification facility, under heavy showers environment, be involved in the rubbish of pipe-line system by rainwater With foreign material not only easy blocking pipeline, natural water area can be caused environmental pollution equally.

In order to solve upper problem, country proposes " sponge city " this concept, i.e. new for modern city design Type storm water man-agement concept, makes urban infrastructure can adapt to environmental change, it is possible to the impact that elastic reply rainwater brings, in fall Water suction, water-retention, infiltration, water purification during rain, utilize the rainwater release after storage process when necessary.

Before rainwater enters final collection container, it is necessary to rainwater is filtered, in conventional defecator, due to whole Individual pipeline is arranged on below ground, and the impurity that defecator leaches cannot be cleared up quickly and effectively with rubbish, causes device Reduce to later stage filter efficiency, safeguard extremely difficult.

Utility model content

The purpose of this utility model is: provide a kind of U-shaped piping installation for carrying out dmp filter purification, by under State technical scheme to realize:

A kind of U-shaped dmp filter purifier, one end, described U-tube road is provided with water inlet, and the other end is provided with collection Mouthful, it being provided with reverse filter element below collection port, bottom U-tube, be provided with sewage draining exit and blow-off line, top is provided with inspection Repair mouth.

As selection, blow-off line is provided with check valve.

As selection, water inlet area is more than sewage draining exit area.

As selection, sewage draining exit is provided above ball-cock assembly, and ball-cock assembly includes ball float, connecting rod and bulb stopper.

As selection, bulb stopper is provided with leakage mouth.

As selection, described reverse filter element includes framework and filtering module, and lower portion is provided with several layers and crosses filter grid, Filtering module was arranged in filter grid.

As selection, being provided with filtering core in filtering module, the size of filtering module, size are the most equal, from each other Replaceable.

As selection, described filtering core is quartz sand, activated carbon, filter screen or filter cloth.

As selection, in described framework, it is provided with three layer filtration lattice, arranges by dmp filter direction, lower floor's filtering module The quartz sand that filtering core is 50 mesh, intermediate layer is the quartz sand of 100 mesh, and top layer is activated carbon.

Feature of the present utility model is:

1. have employed U-shaped circuit design, various complex environment, convenient construction can be applied to flexibly；

2. filter element uses same size, the filtering module of size, can replace at any time with each other, is safeguarding or was adjusting During filter demand, filtering module is extracted out in crossing filter grid and replace；

3. filtering core uses various material, can change at any time according to filtration needs；Miscellaneous by rainwater of lower floor and middle level Matter and large-scale particulate matter filter, and fine particle thing is adsorbed by top layer activated carbon, to reach rainwater purification purpose；

4. it is provided with ball-cock assembly on sewage draining exit, when liquid level savings is to after to a certain degree, and sewage draining exit is closed by ball-cock assembly, enters one Step improves liquid level savings speed；

5. being provided with leakage mouth on bulb stopper, after water inlet stops water inlet, the rainwater in pipeline is discharged from leakage mouth, liquid level In after dropping to certain phase, ball-cock assembly opens sewage draining exit, pipeline, residue rainwater is discharged from sewage draining exit, takes away Partial filtration simultaneously Remaining impurity, device resets, and waits and filtering next time；

6. it is provided with check valve on blow-off line, prevents the sewage in municipal administration blowoff line from entering in device.

In sum, the beneficial effects of the utility model are, arrange flexibly, use reverse filtering scheme, efficiently solve Filtration residue automatically clean emission problem, filter efficiency is high, it is simple to safeguard.

Accompanying drawing explanation

Fig. 1 is cross-sectional view of the present utility model；

Fig. 2 is the close-up schematic view of sewage draining exit and ball-cock assembly；

Fig. 3 is the structural representation of reverse filter element；

In figure, 1 is water inlet, and 2 is collection port, and 3 is reverse filter element, and 4 is sewage draining exit, and 5 is blow-off line, and 6 is single To valve, 7 is access hole, and 8 is connecting rod, and 9 is bulb stopper, and 10 is leakage mouth, and 11 is ball float, and 12 was filter grid, and 13 filter for top layer Module, 14 is intermediate layer filtering module, and 15 is bottom filtering module, and 16 is framework.

Detailed description of the invention

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

With reference to shown in Fig. 1-Fig. 3, a kind of U-shaped dmp filter purifier, one end, described U-tube road is provided with water inlet 1, The other end is provided with collection port 2, is provided with reverse filter element 3 below collection port 2, is provided with sewage draining exit 4 and row bottom U-tube Dirty pipeline 5, water inlet 1 area is more than sewage draining exit 4 area, blow-off line 5 is provided with check valve 6, and top is provided with access hole 7, sewage draining exit 4 is provided above ball-cock assembly, and ball-cock assembly includes ball float 11, connecting rod 8 and bulb stopper 9, and bulb stopper is provided with leakage mouth 10, reverse filter element includes framework 16 and the filtering module being arranged in filter grid 12, and the size of filtering module, size are homogeneous Deng, the most replaceable.The quartz sand that filtering core is 50 mesh arranged in bottom filtering module 15, intermediate layer filtering module 14 is the quartz sand of 100 mesh, and top layer filtering module 13 is activated carbon.

Workflow of the present utility model is:

1. rainwater enters from water inlet 1, and after being filtered the last time, remaining impurity is gone out from sewage draining exit 4, due to sewage draining exit 4 Area is less than water inlet 1, and therefore rainwater is put aside at U-shaped BOP；

2. after liquid level puts aside certain position, sewage draining exit 4 is closed by ball-cock assembly, improves liquid level savings speed further；

3. rainwater passes through reverse filter element 3, is entered rainwater-collecting pipeline by the rainwater after filtering by collection port 2；

4., after water inlet 1 stops water inlet, in U-tube road, the rainwater of savings leakage mouth from ball-cock assembly bulb stopper is slowly arranged Go out；

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 simultaneously Filtering remaining impurity, device resets, and waits and filtering next time.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
