Description

Complex filter

The utility model relates to a kind of complex filter, is particularly useful for the higher water sources of metal ingredient content such as iron, manganese, tin are carried out water filtration.

Existing filter mainly contains two kinds of husky filter and angie type filters, wherein the structure of husky filter is to charge into sand in a cavity, and the both sides of this sand bed are respectively equipped with the current entry and exit, when current process sand bed, sand bed can intercept the bigger impurity of particle, can adsorb a certain amount of fine impurity simultaneously.Existing angie type structure of filter is to establish one deck aperture plate between the current entry and exit, in order to intercept large granular impurity.The weak point of existing various filters is that its volume is big, installation period is long, operational management is cumbersome, filter efficiency is low, working resistance is big, water quality has cyclically-varying and its life-span is shorter.

The purpose of this utility model is to provide a kind of complex filter, to improve the operating efficiency of filter.

The technical scheme that the utility model adopted is that this complex filter is by housing, composite filter and linear electromagnet are formed, the two ends of its middle shell are respectively equipped with water inlet and delivery port, between described water inlet and delivery port, be provided with composite filter along the housing cross section, composite filter comprises the multilayer stainless steel filtering net, the pore size of every metafiltration net is different, described each metafiltration net is arranged in order from large to small by pore size separately, the filter screen of hole maximum is positioned near water inlet one side, the filter screen of hole minimum is positioned near delivery port one side, and has horizontal irregular dislocation between the hole of each metafiltration net.Described linear electromagnet is located in the housing near the composite filter place, causes short circuit for preventing that electromagnet from contacting with water in the housing, can overlap a separation sleeve outside this linear electromagnet, and this separation sleeve should utilize nonmagnetic substance to make.For preventing the electromagnet heating burnout, can in above-mentioned separation sleeve, charge into cooling fluid, the cooling fluid that is adopted can be alcohol, transformer wet goods, preferably adopts edible oil as cooling fluid during Drinking Water, causes the accident in case leak because of cooling fluid.

The bigger impurity that contains in the water can directly be held back by this combination filtering layer; simultaneously owing to have the hole variation in this composite filter in a longitudinal direction; horizontal direction has the irregular dislocation of hole; cause the water stream channel complications changeable; the water velocity difference at each position is very big when small suspended particle or colloid pass through in the hole; be easy to mutually collision and flocculation, growing up to being enough to until it is retained down by filtering layer.On the other hand, this combination filtering layer is in the water for a long time, and the iron bacteria in the water can form multilayer irony active filter film (Fe (OH) 32H2O) in the screen surface breeding, and this filter membrane has catalytic oxidation, ion-exchange, the effect of iron ion in the adsorbed water.For handling the higher water of tenor such as iron, manganese, can between described stainless steel screen pack, accompany the irony filter screen, be beneficial to the iron bacteria breeding, form more effectively irony active filter film as soon as possible.The effect of described linear electromagnetic coil is to form electromagnetic field around described composite filter, under the effect of this electromagnetic field, utilize composite filter to be adsorbent bed, can catch, the magnetic particle in the trap water, as iron ion etc., reach the purpose that reduces water quality colourity and total iron amount.

Advantage of the present utility model is: volume is little, efficient is high, working resistance is little, and its installation and maintenance is convenient, can promptly reduce tenor in the water quality, colourity and turbidity, and water purification is provided effectively.

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

Embodiment: this example is described to be a kind of complex filter that is used for Drinking Water, it is by housing 1, composite filter 2 and linear electromagnet 3 are formed, it is one cylindrical that its middle shell 1 is shaped as, its two ends are respectively equipped with water inlet 7 and delivery port 6, be provided with the composite filter 2 of annular between water inlet 7 and the delivery port 6 along housing 1 cross section, the structure of this routine described composite filter 2 as shown in Figure 2, comprise six layers of ring stainless steel filter screen 21 and two-layer irony filter screen 22, the pore size of every metafiltration net is different, wherein each metafiltration net is arranged in order from large to small by pore size separately, the filter screen of hole maximum is positioned near water inlet 7 one sides, the filter screen of hole minimum is positioned near delivery port 6 one sides, and has horizontal irregular dislocation between the hole of each metafiltration net.Described linear electromagnet 3 is located at the middle vacancy of this annular compound filter course 2, causes short circuit for preventing that electromagnet 3 from contacting with water in the housing 1, and the cylindrical separation sleeve 5 of an aluminium matter can be overlapped in these linear electromagnet 3 outsides.For preventing the electromagnet heating burnout, can in above-mentioned separation sleeve 5, charge into edible oil as cooling fluid 4, cause the accident in case leak because of cooling fluid.Because drinking water is had relatively high expectations to cleanliness factor, also comprises fibrage 23 in this routine described filter, this fibrage 23 is located at the side of composite filter 2 near delivery port 6, can a nearly step improve water quality.
