The specific embodiment
Below in conjunction with specific embodiment the utility model is described in detail.
Fibre-ball filtration jar of the present utility model as shown in drawings, it comprises filters tank body 9, and the water distributing plate 10 that has a plurality of holes on it is equipped with in the bottom in described filtration tank body 9.Filtration tank body above the described water distributing plate is provided with hold down gag.In use, fiberfill fibers ball filtering material layer between described water distributing plate and hold down gag.Described hold down gag comprises its excircle sidewall and filters the structural steel 5-4 that tank body 9 inwalls are fitted and are provided with, on described structural steel 5-4, have a plurality of holes, on described structural steel 5-4, be equipped with wire netting 5-3, between described wire netting 5-3 excircle sidewall and inner tank wall, be plugged with peripheral hairbrush 5-5, the diapire of described peripheral hairbrush 5-5 is arranged on the roof of structural steel, and described wire netting 5-3 is provided with the floating drum 5-2 that has water inlet and delivery port on it.On described wire netting, be fixed with immersible pump 17, described immersible pump 17 with its on the flowing line 19 of first valve 1 is housed an end link to each other, to be arranged on filtering tank external filtering outlet on the tank body by opening for the other end of described flowing line, have spiracle at described filtration tank body top, described spiracle with its on breather valve 20 is housed the breathing pipeline be connected, be respectively arranged with the upper limit snap ring in described filtration tank body upper inside wall and bottom, the lower limit snap ring, described upper limit snap ring can with wire netting end face compression fit mutually, described lower limit snap ring can with structural steel bottom surface compression fit mutually, on the sidewall of the filtration tank body that is positioned at upper limit snap ring top, have the air water mouth, described air water mouth is connected with the water outlet pipeline 7 that the admission line 6 of second valve 2 is housed and the 3rd valve 3 is housed on it on it respectively by first connecting line, on described filtering tank body sidewall, have manhole 8, on the diapire of described filtration tank body, have into discharge outlet, describedly advance discharge outlet and be connected with the flowing line 12 that the back with water inlet line 11 of the 4th valve 4 is housed and the 5th valve 21 is housed on it on it respectively by second connecting line.At described filtration tank body top stirring motor 18 is installed, one end of the shaft that the output shaft of described stirring motor is middle with being arranged on the filtration tank body links to each other, the other end of described shaft passes described wire netting and structural steel and is arranged between described structural steel and the water distributing plate, is connected with agitator arm on the other end of shaft.
The preferred described port of export that the flowing line of the 5th valve 5 is housed on it is connected with the water inlet of a gas water separation tank 13, open in the gas outlet of gas water separation tank roof and link to each other with the import of water ring vacuum pump 16 by admission line 14, the outlet of described water ring vacuum pump is connected with exhaust line 15.
Described floating drum can and be annular with structural steel with the axis of symmetry for water pipe and be arranged on the wire netting.
A plurality of holes on the preferred described structural steel and a plurality of holes on the water distributing plate 10 evenly are provided with.
The operation principle of this device is as follows:
During filtration, water enters by back with water inlet line 11 filtered water inlet mouth at the bottom of the jar, enters a jar interior fiber-ball filter media layer by water distributing plate 10 and enters the filtration state.This moment hold down gag the floating drum expelling tube in the counterweight water, the band floating drum hold down gag that originally is used to compress the fiber-ball filter media layer is floated with current, when hold down gag rises to the upper limit snap ring, fix.Filtrate is the same with traditional fibre ball filter tank, rises with current, is forming a filtering layer of dredging close perfect condition down, performance filtration below the hold down gag.Have a plurality of even distributions hole on the structural steel 5-4 of hold down gag, it is in the collect cavity that filter back water enters the hold down gag top via these holes, will filter in the water drain tank of back by water outlet pipeline 7, enters the next stage handling process.
After filter material layer has been held back a large amount of pollutants, will inevitably cause and filter the increase of intake-outlet pressure reduction, just need carry out backwash this moment to recover the retaining power of filtrate.During backwash, at first open the breather valve 20 on the tank body, and in floating drum, be full of ballast water, open draining submersible sewage pump 17 simultaneously, pass through in flowing line 19 drain tanks by immersible pump 17 suction backs, because sewage constantly is discharged from, the hold down gag loss of buoyance reduces along with the reduction of liquid level, its gravity pressure moisture in the fibrous nodules of squeezing out, when constantly dropping to desired location, blocked compacting device by the lower limit snap ring, because proof submersible sand discharging pump is to be connected with flowing line by flexible pipe, so proof submersible sand discharging pump can descend along with compacting device, to greatest extent with sewage discharge in the jar, this moment, jar interior sewage was discharged from substantially, and this is the draining terminal point.Enter steam afterwards and strengthen the washing stage, when strengthening steaming, admission line 6 from tank deck after the mist of compressed air and steam mixes enters in the jar with certain pressure, because the existence of vapours, sticking to sump oil on the fiber-ball filter media will break away from fiber-ball filter media and discharge with high velocity air, sewage remaining in the filtering layer also can be taken out of filter tank with high velocity air, thereby makes the interior residue of filter tank sewage arrange faster totallyer.Steam clean time remaining 5~10 minutes (also can move actual conditions adjustment) according to the scene.After the steam clean stage finishes i.e. flushing end, enter next filter cycle.Be provided with under the situation of water ring vacuum pump, then strengthen the washing stage at steam, the ring vacuum pump of fetching boiling water, suction gas water separation tank upper gas, make and form micro-vacuum state in the knockout drum, gas passes through filter material layer at a high speed, pollutant residual in the filtering layer and sewage are expelled to gas water separation tank with the flowing line 12 of air-flow at the bottom of the jar, residue sewage in the filter tank and steam reach the purpose of thorough cleaning because pressure differential also will constantly drain into gas water separation tank simultaneously, liquid level maintenance balance is a steam clean stage terminal point in gas water separation tank, at last sewage in the gas water separation tank is drained into the sewage jar, whole flushing process promptly finishes, and enters next filter cycle.
