In the joined state of the lower end of FIG. IV, the edge of the filter medium 32 is projected upward as shown in FIG. 4 II, and the projected edge is heated by a burner or the like. By this heating, the edge of the filter medium 32 is contracted by heat as shown in FIG. 4 III, and covers the diameter-reducing projection 36b and comes into close contact therewith. As a result, the filter medium 32 comes into close contact with the upper edge of the coil 31, and the rim 33 of the filter cylinder 30 is formed.

上する。As shown in FIG. 5, the filter cylinder 30 is inserted into the connecting hole 12 formed in the partition plate 13 from above, and the mouth 33 is hung from the peripheral edge of the connecting hole 12 to be suspended. The connecting hole 12 has an inverted conical shape that substantially coincides with the expanded diameter stepped portion 36a of the coil 31, so that the filter cylinder 30 is locked with the expanded diameter stepped portion 36a in the connecting hole 12 and The diameter-reducing projection 36b at the upper end projects upward (FIG. 5I). Then, on the partition plate 13, a holding plate 15 having a through hole 14 which is vertically aligned with the connecting hole 12 is attached and connected to each other by a bolt 16. (Fig. 5 II). At the time of this connection, the diameter-reducing protrusion 36b of the coil 31 is pressed against the periphery of the through hole 14 to elastically contract, and the urging elastic force thereof causes the diameter-increasing stepped portion 36a.
Is pressed against the connecting hole, and the filter cylinder 30 is held without rattling. Therefore, the liquid to be treated, which does not permeate through the filter medium 32 of the filter cylinder 30 through the connecting hole 12, does not flow around the connecting hole 12 into the sub tank 23, so that the water sealing property is improved.

縮状態にある。Next, the operation of the above filtering device will be described. When the open / close valve 8 and the open / close valve 26 are opened and the liquid to be treated flows in from the supply port 7,
The liquid to be treated flows from the through hole 6 into the main tank 22. The liquid to be treated passes through the filter medium 32 and flows into each of the filtration cylinders 30 and is subjected to a filtering action to become a clean liquid. The clean liquid filtered by the filter material 32 of the filter cylinder 30 flows into the sub tank 23 and flows out from the outlet 24 to a required portion via the pipe 25. During this filtering operation, the filter cylinder 30 is in a contracted state by the pressure from below as shown in FIG. 2I.
前記濾過作業を連続すると、濾材32の表面に濾過質層が
形成され、濾材32に目詰まりを生じ、液槽1内の水圧が
上昇する。この圧力上昇を公知の圧力検出手段により検
知し、次の逆洗工程に入る。When the filtering operation is continued, a filter layer is formed on the surface of the filter medium 32, the filter medium 32 is clogged, and the water pressure in the liquid tank 1 rises. This increase in pressure is detected by a known pressure detecting means, and the next backwashing process is started.
すなわち、まず開閉弁8及び開閉弁26を閉じて、ドレイ
ン口10の開閉弁11を開放し、さらに切換弁28を切換え
て、加圧気体供給源27からゲージ圧1〜1.8Kg/cm2程度
の加圧空気を流出口24に連通させる。That is, first, the on-off valve 8 and the on-off valve 26 are closed, the on-off valve 11 of the drain port 10 is opened, and the changeover valve 28 is changed over so that the gauge pressure from the pressurized gas supply source 27 is about 1 to 1.8 kg / cm 2. The pressurized air of is communicated with the outlet 24.

れる。この洗浄後の液はドレイン口10または液回収口17
から排出される。Then, the cleaning liquid in the sub tank 23 and the filter cylinder 30 is discharged from the filter medium 32 due to the pressure thereof. At this time, since the internal pressure of the filter cylinder 30 becomes larger than the surrounding water pressure, the coil 31 that has contracted during the filtering process expands in the vertical direction as shown in FIG. 2 II due to the restoring elasticity. For this reason, even if the filtration material layer x is formed on the peripheral surface of the filter medium 32, cracks and peeling are generated in the filtration material layer x, and the cleaning liquid is jetted out and washed out. The liquid after this cleaning is drain port 10 or liquid recovery port 17
Emitted from.

xの除去が効果的になされる。When the liquid level in the filter cylinder 30 comes below the partition plate 13,
The pressurized air also acts on the liquid surface of the tubular body 2, causing the liquid surface to drop. In this case, when the liquid level drops, the pressure air permeates through the filter medium 32 from the inside of the filter cylinder 30 and is ejected toward the liquid surface side. Further, when the liquid surface drops due to the interfacial pressure of the liquid surface, the filter material has a peeling action. Accordingly, in combination with the extension of the filter cylinder 30, the filtration material layer x is effectively removed.
前記逆洗処理にあって、まず副槽23,濾過筒30を閉鎖し

圧空気に導通することにより濾材32から液の噴出を生じ
させることができることとなる。In the backwash process, first, the sub-tank 23 and the filter cylinder 30 are closed, and then atmospheric pressure or the like is applied to the liquid level in the tubular main body 2 to remove it, and then the sub-tank 23 and the filter cylinder 30 are removed. Pressurized air may be communicated with the inside of the filter 30 and jetted outward from the filter medium 32. That is,
After the liquid in the liquid tank 1 has flowed down, the cleaning liquid in each filter cylinder 30 closes the on-off valve 26, clogs the filter medium 32, and filters 32.
It is confined in the filter cylinder 30 by the action of atmospheric pressure from the outer peripheral surface. For this reason, after that, the liquid can be ejected from the filter medium 32 by connecting the pressurized air to the inside of the filter cylinder 30.
そしてこの場合にあっても、濾過筒30の伸張により濾過
物層xの剥落を生じる。Even in this case, the filtration layer 30 is exfoliated due to the expansion of the filter cylinder 30.

なる。The expansion and contraction action of the filtration cylinder 30 can be adjusted by setting the spring elasticity of the coil 18, and the expansion and contraction degree can be increased by lowering the spring pressure. For this reason, if it is made to contract greatly during the filtration process, it is possible to cause the restoring extension of the filtration cylinder 30 and to cause the peeling action by merely stopping the filtration process and stopping the flow of the liquid. become.
前記した清浄液の流出後、開閉弁11を閉じ、切換弁28を
切換え、かつ開閉弁26及び開閉弁8を開放すると、液槽
1内に被処理液が流入して、濾過作業が再開される。After the above-mentioned clean liquid flows out, the on-off valve 11 is closed, the switching valve 28 is switched, and the on-off valve 26 and the on-off valve 8 are opened, the liquid to be treated flows into the liquid tank 1, and the filtration work is restarted. It

る優れた効果がある。<Effect of the Invention> As described above, according to the present invention, the filter cylinder is constructed by stretching the filter material on the circumferential surface of the coil. And a diameter reducing projection is formed above the locking portion to hold the diameter expanding locking portion between the partition plate and the holding plate, and the diameter reducing projection is provided around the through hole. Since they are elastically contacted, the expanded diameter locking part of the coil is pressed into contact with the retaining hole of the partition plate, the filter cylinder is held by the partition plate without looseness, and the liquid that does not permeate the filter medium flows from the connecting hole and flows into the sub tank. There is an excellent effect of improving the water sealing performance at this mounting portion.

A filter material, such as a fiber material or a cloth material, is provided around the outer peripheral surface of the long coil, and one or more stretchable filter cylinders having one end as an open end and the other end as a closed end are hung on the partition plate. And the opening end of which is communicated with the sub tank, the upper end of the coil of the elastic filtration tube is expanded in diameter to form an expanded diameter locking portion, and the diameter is further reduced above the locking portion. Along with connecting the protrusions, the stretchable filter cylinder is inserted from above into the connection hole formed in the partition plate that partitions the sub-tank of the cleaning liquid, and the diameter expansion locking part is hung on the periphery of the connection hole and suspended. Then, a retaining plate having a through hole that is vertically aligned with the connecting hole is formed on the partition plate, and the reduced diameter projection of the coil is elastically contacted around the through hole. A filtration tube holding device for a filtration device, characterized in that
