〔産業上の利用分野〕
本考案は、上・下水、用水、産業廃水などに含
有される懸濁物質(SS)を分離除去し、清澄化
する清澄ろ過装置に関するものである。[Detailed description of the invention] [Field of industrial application] The present invention relates to a clarification filtration device that separates and removes suspended solids (SS) contained in water, sewage, industrial water, industrial wastewater, etc. for clarification. It is.
高濁度原水に対応できる清澄ろ過装置として、

As a clarifying filtration device that can handle highly turbid raw water,
Filtration devices that use sponge as a filter medium have come into use, and cleaning of the sponge filter medium can be broadly classified into the following two types.
空気、水により同時洗浄する方法。 Method of cleaning with air and water at the same time.
スポンジの弾性を利用し、スポンジを圧縮し
てスポンジ内のSSを排出する方法。 A method that utilizes the elasticity of a sponge to compress the sponge and discharge the SS inside the sponge.

とながら圧縮用に空気源が必要になることであ
る。 In the above method, during cleaning, the liquid and sponge remaining in the tank are compressed by compressed air flowing from the top to the bottom of the filter tank, and the sponge inside the filter is compressed.
SS is what is removed. The advantage of this method is that the liquid can be removed in a short time, but the disadvantage is that after each cleaning the filter tank has to be filled with the raw water to be filtered, and of course there is no air source for compression. It becomes necessary.

の何らかの動力源が必要になることである。 Further, in the above method, the sponge is surrounded by one fixed perforated plate and one perforated plate connected to the piston, and these two perforated plates are brought closer together with the help of the piston. This compresses the sponge, but the disadvantage is that the water in the filter tank must be drained before compression, and it must be filled with raw water after cleaning, which takes time, and it takes time to move the piston. An air source or some other power source is required.

An embodiment of the present invention will be described with reference to the drawings. In Fig. 1, 1 is a pressure filter tank, a lower perforated plate 2 is fixed to the lower part of the tank, and a float 3 is connected to the upper part. Although the upper perforated plate 4 is placed in a floating state, a stopper 5 is provided on the tank peripheral wall to restrict the float 3 from rising too high. A sponge filter material 6 is filled between the lower perforated plate 2 and the upper perforated plate 4, but water-permeable materials such as nets can also be used for these perforated plates, and the openings are filled with the sponge filter material 6. Make sure it does not leak out.

A rolled one is used.
また、上部多孔板4の上部には、液の下向流を
受圧することにより、閉じて液の流通を制限し、
液の上向流で開いて液の流通を妨げないようにし
た受圧板となるフラツパー7を、図示例のように
フロート3又は上部多孔板4に枢着する。 In addition, the upper part of the upper perforated plate 4 receives pressure from the downward flow of the liquid and closes to restrict the flow of the liquid.
A flapper 7, which serves as a pressure receiving plate that opens with the upward flow of the liquid so as not to obstruct the flow of the liquid, is pivotally attached to the float 3 or the upper perforated plate 4 as shown in the illustrated example.

る。 Furthermore, a raw water inflow pipe 8 is provided at the bottom of the lower perforated plate 2.
and a washing drain pipe 9 are connected via a three-way switching valve V 1 , and a treated water outflow pipe 10 is connected to the top of the filtration tank 1 .
are connected via a treated water outflow valve V2 , and this treated water outflow pipe 10 also serves as a wash water inflow pipe.

0から流出する。 During filtration, as shown in Figure 1, the pressurized raw water flows from the raw water inlet pipe 8 to the three-way switching valve V1.
The water enters the tank through the lower porous plate 2, passes through the sponge filter medium 6 in an upward flow, is filtered, becomes treated water, passes through the upper porous body 4, opens the flapper 7 and flows upward, and the treated water Processed water outflow pipe 1 via outflow valve V 2
Flows from 0.

材の洗浄を行う。 If this kind of filtration is continued for a long time, the filtration resistance will increase, and in some cases, SS will begin to leak into the treated water, as in conventional filtration equipment, so the filter media should be cleaned.

V1を切替えて槽内を洗浄排水管9に連通させ、

洗浄排水管9から排水される。 To clean the filter media, use the 3-way switching valve as shown in Figure 2.
Switch V 1 to communicate the inside of the tank with the cleaning drain pipe 9,
In this state, cleaning water (treated water or raw water may be used) is introduced into the tank from the treated water outflow pipe 10. At this time, the flapper 7 closes and the upper perforated plate 4 is lowered by the pressure of the washing water, and the sponge filter medium 6
It compresses and discharges the trapped SS. On the other hand, the cleaning water flows downward from the peripheral area of the float 3 and other gaps, and is accompanied by the SS discharged from the sponge filter medium 6, passing through the lower perforated plate 2 and the three-way switching valve V1 , and then flowing from the cleaning drain pipe 9. Drained.

1図のようなろ過状態になる。 After discharging the SS to the outside of the tank, if the three-way switching valve V 1 is switched to cut off the communication with the cleaning drain pipe 9, the pressure will be the same on the top and bottom surfaces of the float 3, which will reduce the elasticity of the sponge filter medium 6. The upper porous body 4 rises due to the floating of the float 3 and returns to the position where it is pressed by the stopper 5. Thereafter, if the inside of the tank is further communicated with the raw water inlet pipe 8 through the three-way switching valve V1 , a filtration state as shown in FIG. 1 is achieved.
また、スポンジろ材6の1回の圧縮だけでSS

る上部多孔板4の下降、上昇を繰り返せば良い。 In addition, SS can be achieved by compressing the sponge filter medium 6 only once.
If the discharge is not sufficient, the upper porous plate 4 may be lowered and raised repeatedly using the washing water.

V3を介して連結したものである。 FIG. 3 shows another embodiment of the present invention, in which the area of the float 3 of the first illustrated example is increased, a float 13 is used which also serves as a pressure receiving plate, the flapper 7 of the first illustrated example is omitted, and the treated water is The connecting position of the outflow pipe 10 is between the floating upper limit position of the float 13 and the upper perforated plate 4, and the washing water inflow pipe 14 is connected to the washing water inflow valve at the top of the tank.
It is connected via V3 .

浄するものである。 Therefore, during filtration, the treated water filtered by the sponge filter medium 6 in an upward flow flows out from between the float 13 and the upper perforated plate 4 through the treated water outflow pipe 10,
During washing, as shown in FIG. 4, the three-way switching valve V1 was switched, the treated water outflow valve V2 was closed, and the washing water inflow valve V3 was opened, and the washing water was introduced from the upper washing water inflow pipe 14.
The float 13 receives pressure from the washing water, and the upper porous plate 4 descends to compress and wash the sponge filter medium 6.

で、V4は原水流入弁を示す。 FIG. 5 further shows another embodiment of the present invention,
The positions of the raw water inflow pipe 8 and the treated water outflow pipe 10 of the example shown in the third figure are reversed to perform downward flow filtration, and V4 indicates the raw water inflow valve.
従つて、ろ過時には、原水はフロート13表面

V1を切替え、原水流入弁V4を閉じ洗浄水流入弁
V3を開いて、第4図示例と同様の洗浄が行われ
る。 Therefore, during filtration, raw water passes through the upper perforated plate 4 and is filtered by the sponge filter medium 6 in a downward flow without applying pressure to the surface of the float 13, and the treated water is
The treated water flows out from the outflow pipe 10 via the direction switching valve V1 . Also, when cleaning, use the 3-way switching valve as shown in Figure 6.
Switch V 1 , close the raw water inflow valve V 4 , and close the cleaning water inflow valve
V 3 is opened and cleaning similar to the fourth illustrated example is performed.

よい。 In addition, in each of the above embodiments, when treated water or other clear water is used as the washing water, filtration can be restarted as it is after washing, but if the raw water is relatively clean, the raw water may be used as the washing water. In that case, by branching the raw water inflow pipe and connecting it to the wash water inflow pipe, cleaning can be performed simply by opening and closing the valve without the need to start or stop the pump, but filtration cannot be restarted. Immediately after, it is preferable to drain the treated water from the washing drain pipe 9 for a certain period of time.
