Abstract
The invention discloses a multi-cabin efficient media filter which comprises supporting legs, repair manholes, a water distributor, lifting lugs, an exhaust valve, a water inlet assembly and a water outlet assembly, and further comprises upper-layer, middle-layer and lower-layer porous plates which all sleeve a main water inlet pipe, wherein filter caps are arranged on the porous plates; different filter materials are arranged on the filter caps; the filter material on the filter cap of the upper-layer porous plate is anthracite and has the size of 2-4 mm; the filter material on the filter cap of the middle-layer porous plate is quartz sand and has the size of 1-2 mm; the filter material on the filter cap of the lower-layer porous plate is quartz sand and has the size of 0.6-1.2 mm. According to the media filter, the whole inner cabin is divided into upper, middle and lower cabins through the upper-layer, middle-layer and lower-layer porous plates, and the filter materials on the upper-layer, middle-layer and lower-layer porous plates are gradually reduced in size from top to bottom, so that the classified filtration is realized; the total number of filtering times is 7, so that the filtering effect can be efficiently guaranteed.
Description
Technical field
The present invention relates to sewage disposal device, be applicable to the muddy water of purified treatment steel rolling, continuous casting in steel plant, the filtration of other filter process and other various water quality in clean circulating water system, and industrial water conditioning system and agricultural, environmental protection use water, the municipal wastewater treatment system such as electric power, petrochemical industry, papermaking.
Background technology
Current medium filter mainly contains high rate filter, medium-speed filter etc.The inside of the medium filters such as existing high medium-speed filter only has one deck porous plate, and all different filtrates are all in a cabin, and filter effect is bad.In addition, if backwash water, atmospheric pressure control bad words and be easy to cause random layer during backwash, once the effect just large heavy discount that random layer filters, and filtrate life cycle is very short.
Summary of the invention
Problem to be solved by this invention is to provide a kind of novel filter, and it can filter water multistagely thus ensure that the effect of filtration.Meanwhile, not random layer during this filter backwash, not only ensure that filter effect but also had extended the life cycle of filtrate.
A kind of multistage subdivision high-efficient medium filter of the present invention, it comprises leg, maintenance manhole, water-locator, hanger, air bleeding valve, water inlet component, outlet component, it also comprises upper, middle and lower three layers of porous plate, upper, middle and lower three layers of porous plate are all enclosed within main water inlet tube, porous plate is provided with filter cap, 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 upper, middle and lower three cabins by upper, middle and lower three layers of porous plate by this practical new medium filter, the size of the filtrate simultaneously in upper, middle and lower three layers from top to bottom diminishes gradually and achieves classified filtering, namely pending water enters water-locator by water inlet component and once filters, remove large granular impurity and large suspension, then through the filtration of filter cap and the filtrate of uniform fold in filter cap being fixed on three layers of porous plate, amount to 6 times to filter, the water-locator of adding beginning filters, this equipment amounts to 7 filtrations, therefore filter effect can be ensured efficiently.
Accompanying drawing explanation
Fig. 1 is the front view of medium filter of the present invention;
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
From accompanying drawing, a kind of multistage subdivision high-efficient medium filter of the present invention, it comprises 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 upper, middle and lower three layers of porous plate 4,3,2, upper, middle and lower three layers of porous plate 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 filtrate at the middle and upper levels in porous plate 4 filter cap is anthracite, and 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.Because the filtrate on every one deck porous plate only has a kind of identical material, random layer can not be caused when anti-cleaning like this, be applicable to filtrate Long-Time Service.
In order to ensure the effect of filtering further, as a modification of the present invention mode, on the 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 from top to bottom.
In order to ensure the effect of anti-cleaning, filter of the present invention also comprises gas circuit assembly, gas circuit assembly comprises main air inlet pipe 9 and branched inlet pipe 9-1, main air inlet pipe 9 is passed in two-layer porous plate 2,3 and is arrived below upper strata porous plate 4 from lower, and branched inlet pipe 9-1 is set below lower floor's porous plate 2 with below upper strata porous plate 4, there is multiple little pore above branched inlet pipe 9-1.Like this, the gas circuit assembly of upper strata porous plate 4 below and below upper strata porous plate 2 makes backwash more thorough, and filtrate is more easily cleaned, thus extends filtrate life cycle.
When using medium filter of the present invention to filter, first by pump, pending water is entered into water-locator 6 by water inlet component 10 once to filter, remove large granular impurity and large suspension, then water enters water cap on upper strata porous plate 4 and anthracite carries out twice filtration, remove oil impurities, partial particulate impurity and suspension, then water cap on middle level porous plate 3 is entered and medium-sized quartz sand carries out twice filtration, remove medium-sized granule foreign and suspension, finally enter water cap on lower floor's porous plate 2 and fine quartz sand carries out twice filtration, remove most of granule foreign and suspension.When carrying out backwash after metre filter a period of time, the all backwashes of every one deck during backwash, every metafiltration material is the same material, and gas circuit assembly 9 is had below lower floor's porous plate 2 and upper strata porous plate 4, make backwash more thorough, also will not random layer, solve medium filter in the past and be just easy to cause random layer once backwash thus reduce the phenomenon of backwash effect.Therefore the present invention can reach the effect of disposing of sewage efficiently, makes sewage reach the standard of reuse.Meanwhile, not random layer during filter backwash of the present invention, not only ensure that filter effect but also had extended the life cycle of filtrate.
