達成されないこと等の問題点が考えられる。``Problem that the invention aims to solve'' In the conventional technology, the clean channel, clean water channel, etc. are provided close to the filter tube, which causes SS particles to be sucked into the filter tube and clog this area. There is a risk. Therefore, cleaning and backwashing are required within a short period of time, making maintenance and operation management difficult. In addition, in the above-mentioned invention related to the present applicant,
Although the clogging problem of the conventional technology has been solved, because it is a batch treatment (a process in which only a portion of the raw water is introduced to the filter), it is difficult to process when a large amount of treated liquid is to be filtered in a short period of time. In addition, if this device is used to process the entire amount, it cannot be expected that a uniform filtrate will be introduced into the filtration column, and uniform filtration will not be achieved.

処理槽又は浄液槽へ送られる。"Function" Next, to explain the function of the present invention, the filtrate inlet 6
The introduced filtrate is guided to the water guide member 4 from the tangential direction, becomes a turbulent flow, moves forward while turning toward the tip of the water guide member 4, and is finally connected to the water guide member 4. The filter tube 7 is reached. The flow rate of the filtrate that has reached the filtration tube 7 is accelerated to form a smooth vortex, and the filtrate moves forward inside the filtration tube 7 while rotating. In this process, the filtrate flows outward through the mesh of the filter tube 7, and the SS is adhered to the inner wall surface of the filter tube 7, and the next SS is deposited on top of this attached SS.
The layers are layered one after another and expanded. At the SS attachment area that has been enlarged to a certain extent in this way, the flow velocity within the inner wall increases, the internal pressure at this area decreases, and a suction force C acts in the inner direction of the inner wall against the attached SS, and the lamination Due to the physical effect of the eddy current colliding with the SS adhering part, this laminated SS is separated from the adhering part,
It is transported forward along with the vortex, reattached, and then peeled off in the same manner as described above. In this way, SS is gradually concentrated and transported forward through repeated movements such as adhesion, peeling, and transport. This concentrated SS is discharged from the sludge outlet 3 as concentrated wastewater. On the other hand, the purified liquid that has been sequentially filtered from the filter tube 7 is transferred to the so-called second gap between the filter body 1 and the filter tube 7.
After reaching chamber 8, this second chamber 8
The generation of vortices is suppressed by the plurality of countercurrent plates 10 provided in the filtration tube 7 (almost no eddy currents are generated), and the filtrate flows in a direction countercurrent to the forward direction of the filtrate in the filtration tube 7. . and the first chamber 5
Since the liquid flow control weir 11 is provided at the connection site with the second chamber 8, the flow of the purifying liquid in the second chamber 8 is suppressed, and the flow velocity is made substantially uniform in the circumferential direction. By suppressing and equalizing this flow rate,
It is expected that the above-mentioned inward suction force C will be further assisted and the peeling effect will be improved. The purified liquid that has reached the first chamber 5 is sent from the purified liquid outlet 2 to a treatment tank or a purified liquid tank (not shown).

過液は順次処理されていくのである。 Next, to explain the function of the present invention, the filtrate inlet 6
The introduced filtrate is guided to the water guide member 4 from the tangential direction, becomes a vortex, moves forward while turning toward the tip of the water guide member 4, and is finally connected to the water guide member 4. The filter tube 7 is reached. The flow rate of the filtrate that has reached the filtration tube 7 is accelerated to form a smooth vortex, and the filtrate moves forward inside the filtration tube 7 while rotating. In this process, the filtrate flows outward through the mesh of the filter tube 7, and the SS is attached to the inner wall surface of the filter tube 7, and the next SS is deposited on top of this attached SS.
The layers are layered one after another and expanded. In the SS attachment area that has been enlarged to some extent in this way, the flow velocity in the inner wall increases and the internal pressure in this area decreases, but on the other hand, the flow rate of purified liquid in the second chamber 8 and first chamber 5, which will be described later. as the internal pressure in this area increases,
A dynamic pressure difference is generated between the inside and outside of the filter cylinder 7. This creates a suction force C toward the inner wall toward the attached SS.
At the same time, due to the physical action of the eddy current colliding with the adhering part of the laminated SS, the laminated SS is separated from the adhering part, transported forward along with the eddy current, reattached, and then peeled off in the same manner as described above. be done. While repeating movements such as adhesion, peeling, and transfer in this way,
The SS is gradually concentrated and transported forward.
This concentrated SS is discharged from the sludge outlet 3 as concentrated wastewater. On the other hand, the purified liquid that has been sequentially filtered from the filter tube 7 reaches the so-called second chamber 8, which is the gap between the filter body 1 and the filter tube 7, and then passes through the second chamber 8.
A plurality of countercurrent plates 10 provided in the chamber 8 suppress the generation of vortices (almost no vortices occur), and the filtrate flows in a direction countercurrent to the forward direction of the filtrate in the filtration cylinder 7. It is. and the first
The purified liquid that has reached the joint with the chamber 5 is blocked by the upward stop plate 13 and rises (toward the filter body), and this rising purified liquid is further blocked by the downward stop plate 12 and descends (toward the water guiding member). Since a so-called liquid flow control weir 11 is provided that suppresses the flow toward the purified liquid outlet direction, as shown in FIG.
The flow of the purifying liquid in the chamber 8 is suppressed, and the flow velocity is made substantially uniform in the circumferential direction. By suppressing and making the flow velocity uniform, the above-mentioned inward suction force C can be further supported, and an improvement in the peeling effect can be expected. The purified liquid that has reached the first chamber 5 is sent from the purified liquid outlet 2 to a treatment tank or a purified liquid tank (not shown). Through such operations, the filtrate is sequentially processed.
