Abstract

PURPOSE:To prevent surely sticking and clogging by the fiber-components, etc. of sludge by forming a stirrer in such a way that the fluid flow blown off in a digestion tank is directed diagonally upward in a radial direction. CONSTITUTION:A gas blowing pipe 6 is disposed in a cylindrical body 3 for draft. Gas blow-off nozzles are disposed diagonally upward at one or plural points to a gas blow pipe 4 in the height direction of the mid-way thereof so as to overhang in the radial direction and to be directed toward the inside wall of the body 3. Then the fluid flow blown off in said pipe is directed radially and therefore the sticking and clogging by the fiber-components, etc. of the sludge are surely prevented.

The sludge in the digestion tank is stirred by moving the sludge from 1-10,000 to Suita at the same time, attracting the sludge by the air lift effect, and transporting it upwards.

１底筒体の３同吹出ノズル５４に連通している。A representative example of a conventional agitation device is explained with reference to Fig. 7 and Fig. 8VyJ. 50 is a draft cylinder whose upper and lower ends are open, and into which the sludge liquid 2 in the digestion tank 1 (Fig. 3
are installed in the same way. Three dregs blowing pipes 5I are arranged in the hollow part of the cylinder 50 (supported by a support body (not shown). For example, a branch v52 is provided in the radial direction at the do part of the blowing rib 51, The upper end opening provided at the tip communicates with the three-blowout nozzle 54 which is essentially a one-bottomed cylindrical body in which only a small drain hole 53 is opened.

作か行なわれる。In the stirring device configured in this way, the blowing pipe 51
The air supplied through the nozzles is led to each blow-off nozzle 54 via a branch v52, and is blown directly upward from the upper end opening thereof. Due to the airsoft effect of this blown air, the sludge liquid 2 of one yen of the digestion tank is attracted into the draft cylinder 50, and the entire inside thereof rises and is discharged from the upper end. As a result, a flow of the sludge liquid 2 almost similar to that shown in FIG. 1 (this figure shows an example of the present invention) is generated in the sludge liquid 2, and a stirring operation is performed.

下させるという根不旧な問題点か残されていた。However, in this type of stirring device, the digested sludge liquid has a high temperature of 1M and contains a large amount of fiber, and moreover, it protrudes into the branch pipe 52 or the radial galley (radius galley), and the blowing nozzle 54 has a large cross-sectional area. Due to the upward opening, the f#i fibers of the digested sludge become entangled with the branch pipe 52 and the blow-off nozzle 54, clogging the inside of the draft cylinder 50 and reducing the agitation effect, which is a persistent problem. A few points were left behind.

The nozzle 7 communicates with the inside of the waste blowing pipe 4, and the discharge port has an elliptical shape when viewed in a horizontally cut plane. Further, the nozzle 7 protrudes radially from the waste blowing pipe 4 and is disposed obliquely upward along the inner wall of the draft cylinder 3. In addition, the blowing pipe 4
The support pipe 6 is connected via a short flange, and the blow pipe 4 and the support pipe 6 are partitioned by a partition plate 8.

。In such a stirring device, when air A is force-fed to the waste blowing pipe 4, the air A changes its shape from the waste blowing pipe 4, reaches the waste blowing (1) nozzle 7, and is flushed against the inner wall surface of the traft cylinder 3. It is blown out diagonally upward in the radial direction, and then in the vertical direction. As a result, due to the air lift effect, the sludge is attracted from the lower end opening of the draft cylinder 3, rises inside the draft cylinder 3, and is discharged from the upper end opening. I want to digest it! A flow similar to the first VJ is formed in the sludge liquid 2 in (2), and a stirring operation is performed.

される。) f: According to the invention, the blow-off nozzle 7 is provided facing diagonally in the radial direction. Therefore, as shown by the arrow in FIG. 2, the sludge liquid that has risen so as to hit the inclined lower surface of the Suita nozzle 7 rises along the 1-drawing surface of the blow-off nozzle 7, so that the sludge fibers and flow It can be lifted as it is without sticking to the surface. Therefore, the fiber content is blown out/
This prevents the inside of the traft cylinder 3 from being clogged due to adhesion to the nozzle 7.

、上昇流か円滑で、繊鑵分の付着かない。- Is the Suita/Zuru 7 uniformly tubular over its entire length, as shown in the example shown, or is the fiber content attached? - It is preferable in that it can be further stopped. Now, looking back at the conventional example shown in FIGS. 7 and 8, the fibers that rise and hit the branch pipe 52 rise along a part of the circumference, but the length of the branch pipe 52 There is no directional flow at all, and at this point, it is easy for the fibers to adhere, and the fibers that hit the lower surface of the Suita nozzle 54 are swept up and disposed of there. On the other hand, in the example of the present invention, the upward flow is smooth and there is no adhesion of fine iron.

This is an example of the lower surface of 51a. According to this example, it is possible to reliably prevent the adhesion of fibers that tend to occur at the attachment part of the blow-off nozzle 7 to the blow-in pipe 4 in the example shown in FIG. Ru.

。3rd specific example> FIG. 6 shows a blow-out/slip 7AQ along the tangential direction of the traft cylindrical body 3 and peeled upward in the radial direction in order to generate an upward swirling flow within the traft cylindrical body 3. Let's look at an example similar to . It should be noted that it is not clear from FIG. 6 that they are aligned upward, or that they are directed upward like in FIG. 3 and the like.

刀は太さなものとなり、繊維分による打着、閉塞は完全
といっていい程防止される。In this example, not only the upward flow but also the swirling flow is generated, so the rising current stirring blade in the tub body 3 is thick, and hitting and clogging due to fibers is prevented. It is completely prevented.

〔発明の効果］ 以上の通り、不発明は吹出流体流が放射方向に林め上方

であるため、旋回効果も加わって、付着・閉塞防止効果
か一層顕在化される。Further, according to the second aspect of the invention, since a swirling upward flow is generated, the swirling effect is also added, and the effect of preventing adhesion and clogging becomes even more pronounced.

ざらに、上昇流が吹出部にわける圧損が極力小ざくなり
円滑となる結果、消化槽内の液の撹拌効果か同りする利
点もめる。Roughly speaking, the pressure loss caused by the upward flow at the blow-off section is minimized and the flow becomes smooth, which has the advantage of equalizing the agitation effect on the liquid in the digestion tank.
