Description
Technical field
The present invention relates to sewage disposal device, the muddy water of purified treatment steel rolling, continuous casting be applicable to steel plant, in clean circulating water system, other filter processes and the filtration of other various water quality, and industrial water conditioning system and agricultural, environmental protection use water, the municipal wastewater processing system such as electric power, petrochemical industry, papermaking.
Background technology
Medium filter mainly has high rate filter, medium-speed filter etc. at present.The inside of the medium filters such as existing high medium-speed filter only has one layer of porous plate, and all different filtrates are all in a cabin, and filter effect is bad.If it addition, backwash water during backwash, atmospheric pressure control bad if easily cause random layer, the effect filtered once random layer is with regard to big heavy discount, and the filtrate use cycle is the shortest.
Summary of the invention
Problem to be solved by this invention is to provide a kind of novel filter, and water can be filtered multistagely thus ensure that the effect of filtration by it.Meanwhile, the most random layer during this filter backwash, not only ensure that filter effect but also extend the use cycle of filtrate.
A kind of multistage subdivision high-efficient medium filter of the present invention, it includes leg, maintenance manhole, water-locator, hanger, air bleeding valve, water inlet component, outlet component, it also includes three layers of porous plate of upper, middle and lower, three layers of porous plate of upper, middle and lower are all enclosed within main water inlet tube, it is provided with filter cap on porous plate, filter cap is placed with different filtrates.
Wherein, the filtrate in the porous plate filter cap of upper strata is anthracite, and its size is 2-4mm；Filtrate in the porous plate filter cap of middle level is quartz sand, and its size is 1-2mm；Filtrate in lower floor's porous plate filter cap is quartz sand, and its size is 0.6-1.2mm.
Whole interior cabin be divide into three cabins of upper, middle and lower by three layers of porous plate of upper, middle and lower by this practicality new medium filter, the size of the filtrate in upper, middle and lower three layers from top to bottom tapers into and achieves classified filtering simultaneously, the most pending water is entered water-locator by water inlet component and once filters, remove large granular impurity and big float, it is then passed through the filtration of the filtrate being fixed on the filter cap on three layers of porous plate and uniform fold in filter cap, amount to 6 times to filter, the water-locator adding beginning filters, this equipment amounts to 7 times and filters, therefore filter effect can be ensured efficiently.
Accompanying drawing explanation

Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
Knowable to accompanying drawing, a kind of multistage subdivision high-efficient medium filter of the present invention, it includes leg 1, maintenance manhole 5, water-locator 6, hanger 7, air bleeding valve 8, water inlet component 10, outlet component 11, it is characterized in that: further comprising three layers of porous plate of upper, middle and lower 4,3,2, three layers of porous plate of upper, middle and lower are all enclosed within main water inlet tube 12, on porous plate, 4,3,2 are provided with filter cap 13, and filter cap 13 is placed with different filtrates.
Its at the middle and upper levels the filtrate in porous plate 4 filter cap be anthracite, its size is 2-4mm；Filtrate in middle level porous plate 3 filter cap is quartz sand, and its size is 1-2mm；Filtrate in lower floor's porous plate 2 filter cap is quartz sand, and its size is 0.6-1.2mm.Owing to the filtrate on each layer of porous plate only has a kind of identical material, so do not result in random layer when anti-cleaning, be suitable for filtrate life-time service.
In order to be further ensured that the effect of filtration, as a modification of the present invention mode, on three layers of porous plate of the upper, middle and lower in the present invention, the filter seam of filter cap 13 is more and more less.
In order to ensure the anti-effect cleaned, filter of the present invention also includes gas circuit assembly, gas circuit assembly includes main air inlet pipe 9 and branched inlet pipe 9-1, main air inlet pipe 9 passes through below upper strata porous plate 4 from lower middle two-layer porous plate 2,3, and below lower floor's porous plate 2 and upper strata porous plate 4 branched inlet pipe 9-1 is provided below, have multiple little pore above branched inlet pipe 9-1.So, upper strata porous plate 4 is below and upper strata porous plate 2 gas circuit assembly below makes backwash more thorough, and filtrate is easier to clean, thus extends filtrate and use the cycle.
When the medium filter using the present invention filters, first being entered in water-locator 6 by water inlet component 10 by pending water by pump is once filtered, remove large granular impurity and big float, then water enters the water cap on upper strata porous plate 4 and anthracite carries out twice filtration, remove oil impurities, partial particulate impurity and float, twice filtration is carried out subsequently into the water cap on middle level porous plate 3 and medium-sized quartz sand, remove medium-sized granule foreign and float, finally enter the water cap on lower floor's porous plate 2 and fine quartz sand carries out twice filtration, remove major part granule foreign and float.Backwash is carried out after filter filters a period of time, it is all backwash of each layer during backwash, every metafiltration material is the same material, and have gas circuit assembly 9 below lower floor's porous plate 2 and upper strata porous plate 4, make backwash more thorough, also will not random layer, solve conventional medium filter and just easily cause random layer once backwash thus reduce the phenomenon of backwash effect.Therefore the present invention can reach to process the effect of sewage efficiently, makes sewage reach the standard of reuse.Meanwhile, the most random layer during filter backwash of the present invention, not only ensure that filter effect but also extend the use cycle of filtrate.
