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

Aeration cleans energy-saving fiber filter bed in a kind of filter element

Technical field

The invention belongs to the fiber filter apparatus field, be specifically related to the interior aeration of a kind of filter element and clean energy-saving fiber filter bed.

Background technology

Use the filter plant of long fibre as filtrate, filtrate is carried out the gas distribution of backwash, water-distributing device all be arranged in down filter plate below, the gas that has certain pressure during backwash, water is by gas distribution, the process of emerging in the eyelet of the water-distributing device eyelet of filter plate down rushes at filter bed, clean 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, can not directly be sprayed onto the filtrate inside of pollution, for the suspension Rapid Cleaning that makes every post fiber filtering inside is fallen, just must strengthen the shake dynamics of filtrate, so just must increase backwash gas, water intensity; In addition 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, it is every that the gusset place is arranged can not be again filtrate, make and the space that many places do not have filtrate occurs on the filter bed, these spaces make fluid flow resistance become very little, backwash gas, water flow away from here in a large number in vain like this, make backwash gas, water intensity more need further increasing so again, so just make backwash efficiency very low, the power of motor of backwash gas, water is bigger, simultaneously also waste the backwash clear water, wasted 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 element to clean energy-saving fiber filter bed.

Aeration cleans energy-saving fiber filter bed in a kind of filter element that the present invention proposes, form by house steward 1, bottom plate 2, pressure pin 3, lower support 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 lower support bar 4 penetrates pressure pin 3 below fiber filtering 5 knees on being positioned at bottom plate 2; 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 lower support pipe 4, an end shutoff of lower support 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 as follows: when filtrate cleans, when lower support pipe 4 feeds backwash gas, water, fiber filtering 5 is pulled up, this moment, fiber filtering 5 distributed in the form of sheets in house steward 1 both sides, 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 to be loosened under the effect that gas exposes to the sun from lower support 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, there are not other various losses, so cleaning efficiency height, 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.

Number in the figure: 1 is house steward, and 2 is bottom plate, and 3 is pressure pin, and 4 is the lower support 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 each 1.6 meters filter tank, at first fiber is wound in 2 meters of girths, 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 and bottom plate 2 are by structure boring shown in Figure 1, and pitch of holes is 40mm, the spacing 30mm in the upper support bar 6 upper and lower holes on the bottom plate 2, 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, upper and lower fixing plate is separately fixed at the support body above and below and fix, lower support 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 pressure pin 3 is installed, one group of fiber filtering 5 all is housed between each fixed head on the every DN15 pipe, upper support pipe 4 and lower support bar 6 are inserted to another section from the end of upper mounted plate 7 and bottom plate 2 simultaneously, fiber filtering 5 has been adorned always, take measures then each lower support bar 6 and upper support pipe 4 ends are fixed, prevent its play; Simultaneously upper and lower fixing plate is respectively connected into integral body.Lower support 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.
