Description

Composite yellow rust water filter

The utility model relates to a kind of water filtration device, is a kind of domestic water, the conditioned water of being applicable to, especially recirculated water filtration system.The main composite yellow rust water filter that filters suspension and metal ions such as iron, manganese.

On the means that purify water, common what adopt is angie type filter, husky jar of filter, membrane technology etc.The impurity that can only intercept big particle diameter that these filter methods have with aperture plate, can't and be present in iron in the water, manganese etc. to the material of nominal particle size and carry out filtering with ionic species, some water filtering system is because it is bulky, the operational management complexity, especially the loss of flood peak is big, water base after the filtration is in the gravity current state, needs the secondary lift in concrete the use, therefore uses not extensive.The filtration system cost that also has is too high, only is applicable to the water systems higher to water quality requirement such as life direct drinking water, medicinal water.

The utility model has overcome above-mentioned a plurality of weak points just, solved the variety of issue that exists in filtering effectively, be that retaining power is strong, certain dirty ability of depositing is arranged again, simultaneously metal ions such as iron, manganese are had the high efficiency yellow rust water filter of adsorption filtration function.

The utility model is by last lower house, and intake-outlet, sewage draining exit, electromagnet and container thereof, screen pack and fixed mount thereof are formed.Last lower house is made by carbon steel, and connected mode adopts the flange mode.The intake-outlet axis direction can be parallel, also can be orthogonal, and main purpose is to reduce the loss of flood peak in installing and using.Sewage draining exit is in the bottom of lower house, and its diameter is 1/3～1/5 of an intake-outlet, the flow velocity of using water wisely and increase flushing water when purpose is blowdown.Screen pack adopts stainless steel filtering net, is divided into three kinds.1.5 times of every kind of aperture differences are installed 10～30 layers for every kind, and the aperture is descending settles from bottom to top, adopts fixed mount to fix, and purpose is to guarantee that cutting of filter screen is dirty and deposit dirty ability.

Electromagnet adopts integral layer around mode, with the supporting situation of electromagnet container under make number of turn maximum, the volume minimum.And it is controlled under the enamel-covered wire regulation serviceability temperature at the heating temp that works long hours.Electromagnet adopts all-metal construction in addition, make its heat radiation better, therefore in long-term use, do not need in the electromagnet container, to inject any cooling fluid, under the dry type state, use, avoided of the pollution and the long-term harm of using cooling fluid to go bad electromagnet is brought of cooling fluid seepage water system.Make the electromagnet work period longer more reliable.The electromagnet container adopts three kinds of combinations of materials to be welded, and the first half adopts carbon steel, and Lower Half adopts stainless steel, and pure iron is adopted in the bottom, and purpose is utilized magnetic field intensity to greatest extent, and remanent magnetism is minimum when making flushing pollution discharge.

By adopting above-described structural design, after water enters housing by water inlet, wherein the impurity of greater particle size is directly held back by filter mesh layer, the iron ion that is dissolved in water is then caught at filter mesh layer by electromagnetic field absorption, on strainer filtering frame, shell inner surface and the electromagnet container outer surface,, impurity is got rid of from sewage draining exit by the outage flushing, water after treatment enters water system by delivery port, has reached the purpose of administering yellow rust water.

Characteristics of the present utility model are: the loss of flood peak is little, magnetic Circuit Design is reasonable, cuts a dirt and deposits that dirty ability is strong, widely applicable, easy for installation, the dry type mode is adopted in the electromagnet heat radiation, has prolonged service life, can to water quality any pollution do not arranged may.Blowdown is reasonable in design, and the blowdown water consumption is few, and blowdown pressure increases relatively, and filth-discharging effect is good, and is easy to use.

Figure of description is the composite yellow rust water filter sectional view.

Below in conjunction with drawings and Examples the utility model is further described.

This example is a kind of composite yellow rust water filter of cycle of treatment water system, it is by upper shell (1), lower house (2), water inlet (8), delivery port (3), sewage draining exit (9), filter mesh layer (7), filter screen fixed mount (6), electromagnet container (4), electromagnet (5) is formed, and last lower house is an ellipse, and the centre connects with form of flanges.Water inlet (8) is on lower house (2), delivery port (3) is on upper shell (1), caliber is Dg200～Dg250, one annular filter stratum reticulare (7) is arranged at the shell flange place between intake-outlet, filter mesh layer is made up of three kinds of stainless steel filtering nets respectively, (40 orders, 60 orders, each 20 layers in 80 orders) installation site is that 40 orders are following, 60 orders are placed in the middle, 80 orders in the above, in the filter mesh layer center, one cylindrical electromagnet container (4) is arranged, the first half is a carbon steel, Lower Half is a stainless steel, the bottom is a pure iron, adopt Welding Structure, the built-in electromagnet of electromagnet container (4) (5) generates an electromagnetic field iron ion in the water is adsorbed, and sewage draining exit (9) is located at the bottom centre place of lower house (2), its caliber is Dg50～Dg80, after water entered housing by water inlet (8), wherein the impurity of greater particle size was directly held back by filter mesh layer (7), and the iron ion that is dissolved in water is then caught in filter mesh layer (7) by electromagnetic field absorption, filter screen fixed mount (6), on shell inner surface and electromagnet container (4) outer surface,, impurity is got rid of from sewage draining exit (9) by the outage flushing, water after treatment enters water system by delivery port (3), reaches the purpose of administering yellow rust water.

The utility model is compared with prior art, has following advantage:

1, owing to the structure of filter mesh layer, namely taken into full account the retaining power of filter, considered again Deposit dirty ability, make and filter the efficient height, the loss of flood peak is little.

2, magnetic Circuit Design is reasonable, and magnetic field force utilizes to greatest extent under the same conditions.

3, electromagnet uses under the dry type state, has prolonged service life, has prevented the contaminant water phenomenon Take place.

4, intake-outlet axis direction is parallel also can be vertical, the loss of flood peak when having reduced installation.

5, the sewage draining exit diameter is 1/3～1/5 of an intake-outlet, has reduced water amount of blowdown, increases the sewer flow velocity.
