Description

The vertical stainless steel water-purifying filter of domestic running water

Technical field:

The utility model relates to running water purification techniques field, the vertical stainless steel water-purifying filter of a kind of domestic running water.

Background technology:

At present, along with industrial expansion, many river pollutions of China are on the rise, and particularly the muddy sewage of paper-making industry and chemical industry discharging brings great harm to drinking water.Now, no matter be the running water that city or rural area are used, handled though all pass through multiprogramming, but still existed a large amount of impurity and bacterium, with the naked eye be difficult at ordinary times see.Some local running water has bilgy odour, and mouthfeel is poor, bad drinks, and directly influences people health, is necessary running water is purified once before drinking again.On present market, though have water dispenser and pure water to sell, the pure water expense is higher, the transportation trouble; Water dispenser needs power consumption, of long duration also can produce problems such as incrustation scale and pollution.

Summary of the invention:

For solving the with serious pollution present situation of present household tap water, the purpose of this utility model provides the vertical stainless steel water-purifying filter of a kind of domestic running water, the impurity in the effective filtering water of this filter energy, purified tap water.

For achieving the above object, the utility model adopts following technical scheme:

The vertical stainless steel water-purifying filter of this domestic running water has the stainless steel filter housing; Water inlet pipe circularizes with two triple valves by three water valves with outlet pipe and is connected; Have a water inlet pipe to insert in the filter on filter top, its surface is surrounded by one deck stainless steel filtering net; A plurality of apopores are arranged on the tube wall of water inlet pipe; There is the active carbon layer of 0.5-1mm particle the position, middle and upper part in filter, and its thickness is 50mm; The active carbon layer that the 2mm particle is arranged in its lower section, its thickness are 100mm; The quartz sand layer that the 1-2mm granularity is arranged below active carbon layer, its thickness are 50mm; Be right after the quartz sand layer that the 4-8mm granularity is arranged below it, its thickness is 100mm; At the filter lower bottom part outlet pipe is arranged, the surface of outlet pipe also is surrounded by one deck stainless steel filtering net, and a plurality of apopores are arranged on the tube wall of outlet pipe.

The vertical stainless steel water-purifying filter of this domestic running water, the water inlet pipe and water outlet pipe structure that its annular connects, water inlet pipe is connected through water intaking valve, pipe joint and water inlet threeway and water inlet; The threeway of the outlet pipe T-Ring shape water pipe bottom of filter bottom also is connected to backwash valve and anti-valve in the annular conduit.

The vertical stainless steel water-purifying filter of this domestic running water also can link together a plurality of filters with pipe fitting, forms multistage water-purifying filter; The delivery port of the first order connects partial water inlet again.

Owing to adopt as above technical scheme, the utlity model has following superiority:

The utility model can effectively filter out impurities, purified tap water, and volume is little, occupation of land is few, not electricity consumption, and have the backwash function, can backwash remove the long-time impurity that uses the after-filter inner accumulated.

The drawing explanation:

Fig. 1 is the vertical stainless steel water-purifying filter of a domestic running water structural representation.

Fig. 2 is the vertical stainless steel water-purifying filter of a domestic running water multistage filtering schematic diagram.

Among the figure: the 1-filter; The 2-stainless steel casing; The 3-water inlet pipe; The 4-water inlet; 5-micropore stainless steel filtering net; The 6-active carbon layer; The 7-active carbon layer; The 8-quartz sand layer; The 9-quartz sand layer; The 10-outlet pipe; The 11-tap; The 12-water intaking valve; The 13-backwash valve; The anti-valve of 14-; The 15-water pipe; The 16-water intaking valve; The 17-water inlet pipe; The 18-filter; The 19-outlet pipe; The 20-backwash valve; The anti-valve of 21-.

The specific embodiment one:

As shown in fig. 1: its filter (1) has stainless steel casing (2), there is a water inlet pipe (3) to insert in the filter (1) on filter (1) top, running water enters water inlet pipe (3) by water inlet (4), water inlet pipe has a plurality of apopores on (3), tube-surface is surrounded by one deck micropore stainless steel filtering net (5), running water comes out from apopore, filters to dirty through micropore stainless steel filtering net (5); There is the active carbon layer (6) of 0.5-1mm the position, middle and upper part in filter, and its thickness is 50mm; The active carbon layer (7) of 2mm is arranged in its lower section, and its thickness is 100mm; The quartz sand layer (8) of 1-2mm is arranged below active carbon layer (7), and its thickness is 50mm; The quartz sand layer (9) of 4-8mm is arranged below it, and its thickness is 100mm; Running water has an outlet pipe (10) through after above four layers of filtration in filter (1) bottom, and the running water after the filtration flows out to tap (11) through outlet pipe (10).

When needs backwash cleaning and filtering (1), close water intaking valve (12), open backwash valve (13), close anti-valve (14), water enters outlet pipe (10) through backwash valve (13), in filter (1), go upward to water inlet pipe (3) after, at this moment open anti-valve (14), close backwash valve, discharge from tap (11).

The specific embodiment two:

As shown in Figure 2:, also can adopt multistage water-purifying filter in the with serious pollution area of water.Running water enters from water inlet (4), enter in the filter (1) through water intaking valve (12), water inlet pipe (3), flow out from outlet pipe (10) then, through water pipe (15) to secondary filter, enter in the filter (18) through water intaking valve (16), water inlet pipe (17), flow out to tap from outlet pipe (19) then.

When needs backwash cleaning and filtering (1), (18), close water intaking valve (12), water intaking valve (16), open backwash valve (13), anti-valve (14), backwash valve (20) and anti-valve (21), running water flows backwards, the backwash filter.
