Description
Technical field
The utility model relates to a kind of filtering ponds.
Background technology
The filter tank is a kind of structures common in the water treatment.What use was more at present is V-type filter tank and shutter filter.Filter need carry out backwash to certain phase, and the V-type filter back washing adopts air purge, and gas, water wash simultaneously, again the mode of washing; In addition; Also be provided with surface sweep washing, former water gets into filter tank, the surface of sweeping the filter wash layer through the aperture of two V-type trench bottoms relative with the backwash rhone; Push dirt, impurity that filtering layer recoils up to rhone; Discharge through rhone with backwashing sewage water, after the backwash, the V-type filter tank gets into the normal filtration stage.But it is big or be double-layer filter material or during for the multilayer filtrate, the backwash in V-type filter tank is not thorough, exists filtrate to run the problem of expecting simultaneously when filtrate thickness.Shutter filter is controlled the backwash water outlet in filter tank through being arranged on turnover panel on the rhone.After backwash finished, filtrate needed sedimentation about 20 seconds, treated turnover panel to be opened after light filter material sinks again, and guaranteed that light filter material can not run off through turnover panel, and can effectively discharge dirt and impurity.Though shutter filter has solved the problem that filtrate runs material, backwash is also relatively more thorough, because the restriction of machinery and control, two turnover panels of a cylinder drive are adopted in general single lattice filter tank, and the limited length of every turnover panel, this has just limited the width in single lattice filter tank.
The utility model content
The purpose of the utility model is to provide a kind of backwash the thorough and unrestricted filter tank of size.
The purpose of the utility model is to realize like this; A kind of filter tank; Comprise water inlet system and overflow system; It is characterized in that: also comprise the rhone that is arranged in the filter tank, be provided with ball float in the said rhone and can close or open, thereby accomplish the discharging of backwashing water through the osculum that the up-down of water level is controlled on the said rhone.
In order further accurately to control drainage speed; Be provided with the ball float tank in the above-mentioned rhone and have independently water inlet, effluent control device; Said ball float is positioned in the said ball float tank and is connected with osculum valve plate on being arranged on said rhone through connecting rod, and the up-down through said osculum valve plate realizes closing or opening of said osculum.
For the ease of the up-down of control ball float, be provided with the ball float tank in the above-mentioned rhone and have independently water inlet, effluent control device, above-mentioned ball float is positioned in the said ball float tank and through connecting rod and is connected with above-mentioned osculum valve plate.
The ball float tank can not intake when guaranteeing the backwashing water draining, and water level can not change, thereby guarantees that osculum is in open mode always, and the wall of above-mentioned ball float tank is higher than the upper edge of above-mentioned osculum.
Slide and accurately control displacement for the ease of above-mentioned osculum valve plate, above-mentioned draining cell wall is provided with track, and said osculum valve plate is arranged in the said track and can slides up and down along said track.
Above-mentioned filter tank also is provided with backwash tracheae and backwash water pipe.
Above-mentioned backwash tracheae is connected with back purge system with the backwash water pipe, and said back purge system is arranged in the filter tank and is distribute water and air pipe or filter filter plate.
The both sides in above-mentioned filter tank are provided with the surface sweep washing water pipe and have the little water hole that a row is used to sweep filter wash material surface.When the backwashing water draining, the little water hole on the said surface sweep washing water pipe is opened discharging and is swept wash water, can make the suspension of filter material surface more be prone to discharge the filter tank.
Above-mentioned water inlet system comprises the total canal of the water inlet that is connected with water inlet manifold and is connected with above-mentioned filter tank through intake chamber that the below of said intake chamber is provided with the total canal of draining; Above-mentioned rhone is connected with the total canal of said draining with ball float tank draining valve through the backwash draining valve respectively with the ball float tank.
Be provided with influent weir between above-mentioned intake chamber and the filter tank, said influent weir is provided with the inlet opening, and above-mentioned draining cell wall is higher than said influent weir height, does not intake in the said rhone during with the assurance normal filtration.
Be provided with into water gate valve between total canal of above-mentioned water inlet and the intake chamber, be provided with the into pneumatic slide valve of water between said intake chamber and the ball float tank, the total canal of said draining is provided with the backwash drainpipe.
Above-mentioned overflow system comprises the overflow well that is connected with the filter tank, and said overflow well is connected with the drainage outlet pipe through the clear water canal.
During filtration, drainage gets into the total canal of water inlet through water inlet manifold, and the gate valve of will intaking is opened, and drainage gets into intake chamber from total canal of intaking, and drainage gets into the filter tank through the inlet opening on the influent weir and begins filter process.During normal filtration, through the water level of pneumatic slide valve and the draining pneumatic brake plate valve adjusting ball float tank of intaking, the position of control ball float, thus the position of control osculum valve plate makes osculum be in closed condition.Water after the filtration flows into overflow well earlier, flows into the clear water canal again, discharges from the drainage outlet pipe at last.When the filtering layer loss of flood peak reached predetermined value, the filter tank began to carry out backwash.During backwash, osculum still is in closed condition, and backwash finishes the back and waits 15～20 seconds; Open the draining of draining pneumatic brake plate valve, the water level in the ball float tank is descended, ball float descends with water level and drives the osculum valve plate through connecting rod and descends; Thereby open osculum, make the backwashing water of considering in the groove drain into rhone, open the backwash draining valve through this osculum; Water in the rhone is discharged into the total canal of draining, discharges through the backwash drainpipe again.When the backwashing water draining, surface sweep washing water is opened, and makes the suspension of filter material surface more be prone to drain.After backwash finishes, close draining pneumatic brake plate valve, open the water inlet of intake gate plate valve, the water level in the ball float tank is risen, the while ball float rises and drives the osculum valve plate through connecting rod and rises, thereby closes osculum, begins a new round and filters.
The utlity model has following beneficial effect, the utility model is provided with rhone and accomplishes backwash through the up-down of ball float in the filter tank, and not only backwash is thorough; And cause when having avoided backwashing water intensity high and run material; Can adapt to the needed high strength backwash of thick filtrate, bilayer and multilayer filtrate, and the size in filter tank and arrange the restriction do not receive equipment, compact conformation; Construction and installation are simple, are easy to control.
