Abstract
The invention relates to a filtering element internal aerating and cleaning energy-saving fiber filter bed, which consists of a header pipe, a lower fixed plate, a supporting rod, a lower supporting pipe, a fiber filtering material, an upper supporting rod and an upper fixed plate, wherein the fiber filter material has a ring structure formed by winding a bundle of fibers; the upper fixed plate and the lower fixed plate, which have holes, are distributed on the two sides of the upper and lower ends of the fiber filtering material; the upper supporting rod is inserted into the upper fixed plate and the fiber filter material from one end; the lower supporting rod is inserted into the supporting rod from a place under the bent part of the fiber filtering material positioned on the lower fixed plate; the two ends of the supporting rod are connected with filtering equipment; the supporting rod enables the lower fixed plate to be fixed on the supporting body of the filtering equipment; the upper fixed plate is connected with a fiber density regulating device; and the lower supporting pipe has a plurality of holes, one end of the lower supporting pipe is plugged and the other end of the lower supporting pipe is connected with a backwashing gas or water header pipe. As the backwashing gas and water can wash the interior of the polluted filtering material directly, the washing efficiency is high and energy is saved.
Description
Technical field
The invention belongs to the fiber filter apparatus field, be specifically related to the interior aeration of a kind of filter unit and clean the fiber filter bed.
Background technology
Use the filter plant of long fibre as filtrate; Gas distribution, the water-distributing device that filtrate is carried out backwash all be arranged in down filter plate below, having during backwash emerges in the gas, the eyelet of water by gas distribution, water-distributing device of certain pressure rushes at filter bed through the eyelet of filter plate down, cleans filtrate is stretching; Every group of fiber filtering after stretching is similar to column; Backwash gas, water can only make progress between each column filtrate and flow, and the filtrate that can not directly be sprayed onto pollution is inner, fall in order to make the inner suspension Rapid Cleaning of every post fiber filtering; Just must strengthen the shake dynamics of filtrate, so just must increase backwash gas, water intensity; Owing to the connection between reasons such as filter plate intensity and each piece filter plate, on filter plate, must be furnished with some gussets in addition, every the gusset place is arranged can not be again filtrate; Make the space that many places do not have filtrate to occur on the filter bed, these spaces make fluid flow resistance become very little, and backwash gas, water flow away from here in a large number in vain like this; Make backwash gas, water intensity more need further to strengthen so again; So just make backwash efficiency very low, the power of motor of backwash gas, water is bigger, also wastes backwash simultaneously and uses clear water; Waste the energy, increased the drainage cost.
Summary of the invention
The object of the present invention is to provide the interior aeration of a kind of filter unit to clean the fiber filter bed.
The interior aeration of a kind of filter unit that the present invention proposes cleans the fiber filter bed; Form by house steward 1, bottom plate 2, pressure pin 3, following stay pipe 4, fiber filtering 5, upper support bar 6 and upper mounted plate 7; The circulus of fiber filtering 5 for being entwined by one group of fiber; The both sides of the upper and lower end of fiber filtering 5 are furnished with upper mounted plate with holes 7 and bottom plate 2 respectively; Upper support bar 6 penetrates upper mounted plate 7 and fiber filtering 5 upper ends from an end, and following stay pipe 4 penetrates bottom plate 2 and fiber filtering 5 bottom bend from an end, and pressure pin 3 is positioned at stay pipe 4 belows down; Pressure pin 3 two ends connect filter plant, and pressure pin 3 is fixed bottom plate 2 on the supporter of filter plant; Upper mounted plate 7 links to each other with the fibre density adjusting device; Be drilled with several apertures on the following stay pipe 4, an end shutoff of following stay pipe 4, the other end links to each other with the house steward 1 of backwash gas or water respectively.
The course of work of the present invention is following: when filtrate cleans; When following stay pipe 4 feeds backwash gas, water; Fiber filtering 5 is pulled up, and this moment, fiber filtering 5 distributed in house steward 1 both sides in the form of sheets, and more evenly and thinner; Have on the backwash gas that sprays the certain angle eyelet, the surface that water directly is flushed to fiber filtering 5 and make it under the effect that gas exposes to the sun, to be loosened from following stay pipe 4, this part just in time is to form filtering layer to pollute more serious fiber filtering 5 the latter halfs; Constantly make fiber filtering 5 overall jitter in the process again gas, the waterborne liter, the suspension of fiber filtering 5 trapped inside just is cleaned easily like this.
Because backwash gas, water can directly clean polluting fiber filtering 5 inside, does not have other various losses; So cleaning efficiency is high; And filtrate also cleans up easily, and used backwash gas, water intensity are also low, and scavenging period can shorten again; So just can save the energy, reduce the drainage cost.
Backwash gas, water can replace downward stay pipe feeding discontinuously fiber filtering is cleaned; Also only feed backwash gas in the stay pipe downwards, and backwash water is provided by former water-distributing device.Because the reduction of backwash gas, water intensity, the pipeline of each system, valve, blower fan, water pump diminish, and also reduce construction costs simultaneously.
Description of drawings
Fig. 1 is a structural diagrams of the present invention.
Label among the figure: 1 is house steward, and 2 is bottom plate, and 3 is pressure pin, and 4 are following stay pipe, and 5 is fiber filtering, and 6 is upper support bar, and 7 is upper mounted plate.
The specific embodiment
Further specify the present invention in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
One in long and wide respectively 1.6 meters filter tanks at first are wound in 2 meters of girths with fiber, 5 some groups of the fibrae circulares filtrates that every group of weight is 0.35 kilogram; Respectively 11 of upper mounted plate 7, bottom plates 2; Upper mounted plate 7 is holed by structure shown in Figure 1 with bottom plate 2, and pitch of holes is 40mm, and being used on the bottom plate 2 inserts down the last hole of stay pipe 4 and be used to insert the spacing 30mm in the following hole of pressure pin 3; The specification of upper support bar 6 is the DN15 pipe, and length is 1.6 meters; Externally in the pond set up simple and easy support body, be separately fixed at upper and lower fixing plate the support body above and below and fix, following stay pipe 4 bores two row φ 2mm holes, and pitch of holes 40mm spends with plumb line angle 25 and is staggered.Each bottom plate 2 spacing 160mm; Earlier install pressure pin 3; One group of fiber filtering 5 all is housed between each fixed head on the every DN15 pipe; Following stay pipe 4 is inserted to another section from the end of upper mounted plate 7 and bottom plate 2 with upper support bar 6 simultaneously; Adorn fiber filtering 5 always, taken measures then each upper support bar 6 and following stay pipe 4 ends are fixed, prevented its play; Simultaneously upper and lower fixing plate is respectively connected into integral body.Following stay pipe 4 one ends block, and the other end links to each other with house steward 1; Integral body is hung in the body of pond, and bottom plate 2 is fixed with the interior support member of pond body, and upper mounted plate 7 is connected with fiber filtering 5 density regulating apparatus, and guarantees that activity freely in the body of pond.In house steward, alternately feed backwash gas, water discontinuously, 5 minutes at interval.
Through on probation, at identical filter cycle of 24h, under the cleaning performance same case after the cleaning, backwash gas intensity reduces 40%, and backwash water intensity reduces 20%, and scavenging period reduces 10%, and energy-saving effect is obvious, reaches leading domestic level.
