Description
Technical field
The present invention relates to a kind of water treatment system, specifically a kind of water process dress with float-type plumbing mechanism
It sets.
Background technology
In water-purifying process, filter is one of pith.In filter process, the impurity that is filtered out in water
It can retain, accumulate constantly in filter material layer, accumulation can excessively not only result in filtering velocity decline, production water efficiency is reduced, and used
Water water quality is unqualified.Therefore it needs to remove the impurity accumulated in filter material layer by backwash.In backwash process, water or air-flow are anti-
To impact filter material layer, the impurity deposited in filter material layer is made to loosen, removed with filtrate, abjection, and suspended in water, arranged later with water
Go out to achieve the purpose that cleaning.Due in backwash process, not only impurity can be flushed out from filter material layer water, part filtrate
It can suspend in water under impact, if backwash drainage pattern is improper, filtrate can be caused to be discharged with water, to cause filtrate to damage
It loses.
Currently, most of filter tanks（Siphon filter, V-type filter tank, D types filter tank, the filter tanks F etc.）Backwashing water discharge outlet be all
It is fixedly mounted, repercussion effect and drainage effect have the following problems.
First, if installation site is excessively high, the muddy water stayed in filter tank after backwash draining is more, then the number backwashed needs
To increase accordingly, if installation site is too low, the filtrate to suspend in water is made a slip of the tongue closely from draining, and filtrate loss will in drainage procedure
It can increase.
Second is that since the liquid level in drainage procedure in filter tank is continually changing, when draining starts, liquid level is higher than discharge outlet,
Water and impurity can be discharged from discharge outlet, and when below the near discharge outlet of liquid level, then drain stopping.Liquid level when initial draining
Height determines time of lasting draining, if starting stage liquid level is excessively high, the filtrate to suspend in water be easy and impurity together by
Discharge, causes filterins media run-off to increase.If starting stage liquid level is too low, water discharge time is too short, it is difficult to impurity fully be discharged, go out
Standard is not achieved in water quality, causes washing time and time to increase, cannot achieve the purpose that energy-saving and water-saving.
Third, in order to reduce filtrate loss when backwash draining, the flow velocity of water is generally not too large when draining, on the water surface
Impurity be short of power, the velocity of discharge is slow, and more difficult is completely exhausted out.The power of liquid level impurity, some are adopted when in order to increase draining
The mode of gas blow pipe is set used in filter tank ullage, it is horizontal on liquid level to blow, to push impurity to be moved to discharge outlet, promote
It is smoothly discharged.But due to factors such as the resistances of the diffusion of air-flow and air, the current rate of gas blow pipe blowout with away from
From increase and weaken rapidly, it is smaller to the impurity impetus of position farther out.Moreover, partial impurities are located at liquid level hereinafter, liquid
Air-flow above face is to its impetus also than relatively limited.Therefore, the mode gas blow pipe of only adjusting the distance that the water surface is blown is closer, and position
Impurity in water surface surface layer is more effective.

Specific implementation mode
Clear, complete explanation is carried out to technical scheme of the present invention below in conjunction with the drawings and the specific embodiments.Below
Particular content listed by embodiment is not limited to skill necessary to the technical solution technical problems to be solved of claim record
Art feature.Meanwhile described enumerate is a part that embodiment is only the present invention, rather than whole embodiments.
As described in Figure 1, water treatment facilities of the invention includes filter tank 1, the filter material layer 5 that is arranged in filter tank 1 and setting exist
The counter-flushing pipeline 10 of 5 lower section of filter material layer, is equipped with water purification outlet 9 on the pool wall below filter material layer 5.It is vertical in the filter tank
If there are one inlet and outlet pipes 2, which enters filter tank, while the also conduct in backwash process for water to be filtered
Drainpipe flows out filter tank for backwashing water.Inlet and outlet pipes 2 are preferably provided at the center in filter tank 1, convenient for liquid when backwash draining
Impurity on face is assembled to center to be discharged.Certainly, the position for inlet and outlet pipes being positioned away to center is also feasible, such as is set
It sets in the side in filter tank.It is discharged correspondingly, the impurity on liquid level needs to assemble to filter tank side.
The lower end of inlet and outlet pipes 2 is connected by water supply line 11 to be filtered outside pipeline and filter tank and washback drainpipe road 12
It connects.When the normal drainage in filter tank, the valve of discharge pipe line is closed, and is passed through and was waited for into filter tank by inlet and outlet pipes 2 from supply line
The water of filter.During filter back washing, supply line is closed, and the impurity connected component water on the liquid level of filter tank is logical through inlet and outlet pipes 2
It is discharged to discharge pipe line.
Valve seat 6 is equipped in the upper port of inlet and outlet pipes 2,6 top of valve seat is equipped with the spool 7 that can be moved up and down.Valve seat 6
The valve being switched on or off with 7 composition control inlet and outlet pipes 2 of spool.The concrete form of valve seat 6 and spool 7 can select as needed
It selects, the present embodiment selects the form of Conical Valve, has the conical seal (contact) face for sealing against each other cooperation on valve seat 6 and spool 7.Shown in
Spool 7 is by driving mechanism 8, such as drives to move up and down by push-rod electric machine and be opened and closed with control valve.According to the valve specifically used
The drives such as hoist cable, screw rod up and down motion can also be used in form.
The present invention is in order to solve the problems, such as that backwash discharge outlet adapts to the variation of filter tank liquid level, in the upper end cap of inlet and outlet pipes 2
If a floating drum 3 that can be suspended in water, the open upper end of the floating drum 3 forms intake-outlet 301.The madial wall of floating drum 3 with
The lateral wall of inlet and outlet pipes 2 is directly slidable, and is sealing.Therefore, it is set with the formation of inlet and outlet pipes 2 of floating drum 3
Upper end telescopic form.The size of force of sliding friction should not hinder floating drum 3 in the floating of water between floating drum 3 and inlet and outlet pipes 2
Rise under force effect, the decline of floating drum under the effect of gravity after equally should not also hindering liquid level to decline.Therefore, the floating drum 3 is practical
On be suspended in water, can float up and down along inlet and outlet pipes 2 with the variation of water level in filter tank 1.Above and below floating drum 3
Float, the also corresponding variation up and down of the height of the upper end intake-outlet 301, and the variation always with the variation phase of liquid level
It adapts to.
As shown in figure 4, when water level increases in filter tank, floating drum 3 rises to one under the buoyancy of water along inlet and outlet pipes 2
A higher position.And with the discharge of dampening, as shown in figure 5, when water level decreasing in filter tank, floating drum 3 is also accordingly along Inlet and outlet water
Pipe 2 declines.But intake-outlet 301 keeps a relatively fixed position with the water surface always.
In normal work, water supply line 11 to be filtered is connected water treatment facilities equipped with the present invention with inlet and outlet pipes 2,
Spool 7 rises under the drive of driving mechanism 8, and valve is made to open.Water to be filtered enters from intake-outlet 301 in filter tank 1, through filter
After filter material layer 5 in pond filters, it is discharged from the water purification outlet 9 on the pool wall of filter material layer lower section.
With the progress of filtering, the impurity deposited in filter material layer 5 gradually increases.When impurity excessively hinders filtering to lead to liquid level
The water purification of predetermined value or discharge is risen to after turbidity is more than predetermined value after testing, can determine whether to need to backwash for filter material layer.This
When, stop the water outlet with water inlet and the water purification for crossing drainage, driving mechanism 8 declines shutdown inlet and outlet pipes 2 with movable valve plug 7.Start anti-
Cleaning procedure carries out backwash gas punching using the counter-flushing pipeline 10 below filter material layer and/or water rushes（As shown in Figure 3）.With
The progress of backwash, impurity are rinsed out from filter material layer, and the liquid level in filter tank is gradually increasing.Floating drum 3 also rises therewith, makes
Intake-outlet 301 keeps a relatively fixed position with the water surface always.After liquid level reaches the high point of setting, stop backwash
Gas rushes and water punching.Driving mechanism 8 rises with movable valve plug 7, and opening valve makes muddy water pass through 301 mouthfuls of intake-outlet and enters inlet and outlet pipes
2, and be discharged through washback drainpipe road 12.
In drainage procedure, since intake-outlet 7 and the relative position of the water surface are fixed always, and the relative position is through anti-
Rinse what experiment was accurately calculated according to the thickness of row's muddy water layer and the buoyancy of floating drum, the upper edge of intake-outlet 7 is in always
The water surface is with next suitable height.Therefore, liquid level both will not be excessive with the difference in height of 7 upper edge of intake-outlet, can prevent filtrate
Enter inlet and outlet pipes 2 with flow and filtrate is caused to lose.Difference in height will not be too small simultaneously, it is ensured that the impurity energy on liquid level
It is enough to be smoothly discharged with water.
Intake-outlet 301 can be made to adapt to the variation of liquid level, intake-outlet 301 and liquid level automatically by the way of floating drum floating
Between can remain the difference in height of setting.The liquid level of filter back washing draining starting stage can be promoted to a higher height
Difference in height when spending without worrying to drain between liquid level and intake-outlet 301 is excessive and filtrate is caused to lose, it is thus possible to subtract
Number is backwashed less, is shortened backwashing time, is improved the service efficiency in filter tank.This self-reacting mode is not required to by liquid level
It measures, a series of troublesome operations such as control system calculates, driving mechanism action, thus, and pass through driving mechanism active control
Method is compared, the adjustment of intake-outlet height and liquid level change between almost without delay, not only precision higher, and need not answering
Miscellaneous control system, terseness and stability are all more preferable.
The intake-outlet 301 of 3 upper end of the floating drum is expanded outwardly in horn-like, and nozzle increases after extension, convenient on liquid level
Impurity collect discharge to it.
Floating drum 3 can be used material with larger buoyancy itself and make, and can suspend in water.Can also use than
The firmer but materials such as heavier metal itself make the main body of floating drum 3, and in the fixed specific larger buoyancy in its periphery can
Swim in the floating body 302 on the water surface.The larger buoyancy of the floating body 302 can be that its material itself is caused, can also
It is realized using frame mode, for example, by using hollow-core construction, such as hollow float.The setting quantity of floating body 302 and specific installation
Mode is set as needed.Such as be directly anchored on the outer wall of cylindrical body, or be fixed on from cylindrical body to extension
In the connection support bar of stretching.In embodiment illustrated in fig. 6, there are four spherical floating bodies for fixation in the form of connection support bar
302, four spherical float bodies 302 are uniformly distributed along the circumferencial direction of floating drum 3, to ensure that 3 surrounding buoyancy of floating drum is uniform.
Limiting device is set in the lower end of floating drum 3, floating drum 3 can be kept to be sleeved in inlet and outlet pipes 2, and is unlikely to due to upper
It rises excessively high and is detached from, it is also possible to limit its maximum lifting height by limiting device.The concrete form of limiting device can be with
Using the form in the inwardly projecting convex block of 3 lower end inside of floating drum setting, with fixed stop member on the outside of 2 upper end of inlet and outlet pipes
It matches and plays position-limiting action.It can also be limited by the way that the form of guide groove and sliding block is arranged.It specifically can root using which kind of form
According to specifically needing to select.Equally, limiting device can also be set in the upper end of floating drum 3, for limiting the maximum that it is moved downward
Stroke, set-up mode are similar with the limiting device of lower end.
In backwash bleeding stage, intake-outlet 301 needs the water surface in filter tank hereinafter, miscellaneous on liquid level to make
Matter can smoothly be discharged.The height that intake-outlet 301 specifically suspends is determined by the buoyancy of floating drum 3 in water, and the buoyancy of floating drum 3
Size can be by selecting type, size, the quantity etc. of buoyant material to be adjusted.By to filtrate in backwash process in water
The characteristics of motion, water surface impurity layer thickness etc. studied, be computed and determine and make the upper edge of 3 upper end intake-outlet 301 of floating drum
5-15cm are proper below the water surface, and optimal is 10cm.Intake-outlet 301 can be in backwashing drainage procedure always
Be maintained at the such position of liquid level or less, impurity can either be made fully to be discharged, but prevent to greatest extent filtrate with water flow into
Outlet pipe 2 reduces filtrate loss.
As shown in Figures 2 and 3, it is equipped with a circle plug-flow pipe 4 along the inner wall in filter tank 1, plug-flow pipe 4 is looped around the four of inlet and outlet pipes 2
Week.The setting height of the plug-flow pipe 4 make its in entirely backwash drainage procedure all in the filter tank water surface under, and to be located at
The top of filter material layer 5 in filter tank.Plug-flow pipe 4 with outside filter tank 1 gas supply or water supply pipe connect, be distributed on plug-flow pipe 4
The spray orifice 401 blown or sprayed water upwards.In backwash process, externally input air or water are sprayed by spray orifice 401 in filter tank,
To push the water flowing in filter tank.Above-described upward air blowing refers to that can be perpendicular to the perpendicular of horizontal plane generally towards upper
Directly upward, can also slightly have deflection.4 injection of plug-flow pipe effect under, near water flowed up along filter tank wall, in filter tank
Wall is formed about upper up-flow.Due to the barrier effect of pool wall, flow can only be spread in uphill process to filter tank center, thus be
The flow layer collected to filter tank center can be formed on liquid level.Impurity on liquid level is assembled under the drive that stream is collected on liquid level upper layer
It is discharged at intake-outlet 301, and through inlet and outlet pipes 2.As plug-flow pipe 4 pushes up the flow near the wall of filter tank, filter tank
Lower layer's flow at center is then spread to pool wall to fill up the vacancy after flow rises, under the upper layer flow at filter tank center is then corresponding
It is heavy.Formed in filter tank as a result, as shown in 4 upper arrow of plug-flow pipe in Fig. 3 by near the inner wall of filter tank upper up-flow, on filter tank
Laminar flow flows to the recirculated water that the diffusion flow of pool wall forms to collect stream, the sinking at filter tank center and the filter tank lower layer at center
Stream.The gas or water that plug-flow pipe 4 constantly sprays provide power for water circulation, since plug-flow pipe 4 floods under water, the water of ejection or
Air-flow can be completely converted into flow dynamic, and compared with the mode that the water surface is blown, there is no cannot be used for pushing after Diffusion of gas stream
The problem of flow, therefore the more efficient of flow is pushed, the discharge of water surface impurity can be effectively facilitated.
The thought for collecting flowing to filter tank center based on circulating water flow utilized above promotion liquid level upper layer impurity, by filter tank 1
Shape be designed as circle, the plug-flow pipe 4 circular along filter tank wall arrangement makes the inlet and outlet pipes 2 and surrounding pool wall at filter tank center
And the distance of plug-flow pipe 4 is equal.On plug-flow pipe 4 uniformly distributed multiple spray orifices 401 injection effect under formed along filter tank
The intensity of multiple circulating water flows of wall circle distribution is also essentially identical, it is thus possible to keep entire filter tank various pieces circulating water flow
Stabilization ensure the 4 high efficiency acting of plug-flow pipe to avoid unnecessary energy loss.
For the spray orifice direction of plug-flow pipe 4, can directly it is vertical upward, form flow using the barrier effect of filter tank wall and follow
Ring.Can also be centroclinal gently towards filter tank by the emission direction of spray orifice 401, it is biased to the oblique upper among filter tank, utilizes inclination
Jet-stream wind or flow promote water circulation.
It is circular in view of filter tank, counter-flushing pipeline 10 can also be annularly arranged in the lower section of filter material layer 5, anti-to make
Air-flow or flow is rinsed to be adapted with circular filter layer.
In 1 embodiment as shown in the figure, counter-flushing pipeline 10 is supplied with the backwash outside filter tank respectively by corresponding valve
