Abstract

The utility model relates to a water treatment tank for water filtration with inside and outside double layers, which comprises an inner filter tank and an outer filter tank. A head cover which comprises a porous plate is arranged on the upper of the inner filter tank, a semi-circular porous plate is arranged on the outlet of the bottom; the filter tank is filled with granular filter materials and a plurality of recoil gas nozzles, and is distributed uniformly on the bottom of the filter tank. An intake, an exhaust outlet and an overflow outlet are arranged on the top of the outer tank, and an outfall is arranged on the bottom. The utility model can filter without pump pressure by a principle of natural water level difference, thereby achieving a goal of low energy consumption, reducing the pollution discharge and saving equipment investment.

Description

Inside and outside double-deck water treatment tank

Technical field

The utility model relates to a kind of water treatment tank, in order to water or other liquid are carried out filtration treatment, removes wherein suspension, dissolubility impurity.The utility model belongs to the plumbing field.

Background technology

Traditional water treatment filtering tank mostly is the individual layer jar greatly, interior dress filtrate only plays single filtration, then need blowdown simultaneously during backwash, when filtering, need keep certain pressure, energy consumption was bigger when this not only filtered, the back flush discharge amount is also very big, therefore, and the occasion that often can not satisfy the demand and recycle after water or other aqueous solution filtered.

Summary of the invention

The purpose of this utility model is the above-mentioned defective that overcomes existing water treatment tank, invents a kind of by internal layer filtering tank and outer jar of inside and outside double-deck water treatment tank that is sleeved on together, so that more effectively water or other liquid are carried out filtration treatment.

The utility model is made up of internal layer filtering tank and outer jar, wherein:

The diameter of internal layer filtering tank is less than outer jar.The top of internal layer filtering tank is by a top cover that is stacked and is formed by porous plate.A semicircle orifice plate is installed on the delivery port of bottom, is covered with stainless (steel) wire above the semicircle orifice plate.In the internal layer filtering tank, be filled with granular filter material.The uniform back flushing air shower nozzle in the jar end.

Outer jar tank deck has water inlet, exhaust outlet and overfall, and there is sewage draining exit at a jar end.

The utility model adopts the principle of natural water level difference, and the method that pumps up just can be filtered.And, only utilize a set of equipment just can make simultaneously than resuspension thing precipitation, light suspension come-up, remaining filters.Filter energy consumption thereby reach to reduce, reduce blowdown flow rate, save the multipurpose of equipment investment.

The advantage of this device is inside and outside the technical process with character such as traditional dosing, flocculation, air supporting, precipitation, filtrations is concentrated to one in double-deck jar, therefore makes occupation area of equipment little, and investment reduces, and has improved the efficient of water treatment.Particularly only depend on water-head to filter, having saved in the past, employing soars the electric energy that pump expends.

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1-water inlet, outer jar of 2-, 3-top cover, 4-internal layer filtering tank, 5-angle ring, 6-air inlet pipe, 7-orifice plate, 8-delivery port, the anti-aerating nozzle of 9-, 10-central intake pipe, 11-sewage draining exit, 12-supporting leg, 13-bolt, 14-exhaust outlet, 15-overfall.

The specific embodiment

The utility model is made up of internal layer filtering tank 4 and outer jar 2.Wherein:

The diameter little 200MM of internal layer filtering tank 4 than outer jar 2.The top cover 3 that the top of internal layer filtering tank 4 is stacked and is formed by a porous plate by multilayer, in device of the present utility model, top cover 3 is made up of 14 layers porous plate.Porous plate adopts commercially available porous galvanized sheet or corrosion resistant plate, connects with logical button bolt 13 each other.The inner tank wall of internal layer filtering tank 4 has been welded 6 muscle that angle ring 5 is formed.A semicircle orifice plate 7 has been installed on bottom delivery port 8 tops of internal layer filtering tank 4, and semicircle orifice plate 7 is a steel plate, covers with stainless (steel) wire above.In internal layer filtering tank 4, be filled with granular filter material from stainless (steel) wire top to going up most a circle angle ring 5, in order to remove suspension and the dissolubility impurity in water or other liquid.Filtrate is porous ceramics, activated carbon, quartz sand or other particulate filter material.The aperture of the porous plate hole of top cover 3 is 5 times of filtrate nominal diameter; Distance between every layer of porous plate is 5 times of filtrate nominal diameter; The mesh of the stainless (steel) wire on the semicircle orifice plate 7 of tank base is less than filtrate nominal diameter 1/2.The jar end at internal layer filtering tank 4 is evenly equipped with the back flushing air shower nozzle 9 that direction makes progress, by air inlet pipe 6 air feed.Spacing between each back flushing air shower nozzle 9 is about 200MM.The back flushing air shower nozzle 9 at center at the bottom of also having one to be positioned at jar below semicircle orifice plate 7, central intake pipe 10 is to its air feed.All cover on the back flushing air shower nozzle 9 with stainless (steel) wire.

Tank deck at outer jar 2 has a water inlet 1.An exhaust outlet 14 and overfall 15 are respectively arranged on the outer tube of water inlet 1, be used to discharge gas and overflow the liquid that the superiors have light suspension., there is a sewage draining exit 11 at outer jar 2 the jar end.

The tank body of whole water treatment tank is supported by supporting leg 12.

During work, the water that is filtered flows into from the water inlet 1 of outer jar 2 tank decks, enters internal layer filtering tank 4 by top cover 3.Suspension and dissolubility impurity are removed in the effect of filtrate in jar.And the stainless (steel) wire on the semicircle orifice plate 7 can stop the impurity that avales, and makes the water that flows out from delivery port 8 reach standard compliant water like this.Sewage draining exit 11 at the bottom of outer jar 2 jars is closed condition when flat, when needs carry out backwash to internal layer filtering tank 4, gas is instead inflated in jar by anti-aerating nozzle 9 by air inlet pipe 6 and central intake pipe 10, jar interior an impurity and a suspension are recoiled away via top cover 3, discharged by the sewage draining exit of opening 11, lighter floating thing also can flow out by the overfall on outer jar 2 15 again.
