とができず、脱水不十分のままである。When removing unfiltered liquid, the P liquid outlet (8) is opened, so the filtrate above the P liquid pipe (5) remaining inside the filter body is discharged, but the disk filtration The P liquid (10) remaining in the lower part of the body is confined in a bag shape until the P slag (9) is scraped off because the TP liquid dispersion pipe is located at a low position. (Fig. 2) Next, by rotating the filter body (4) and scraping off the P slag (9) with a fixed scraper/< -tS+, the filtrate also falls, so the P slag is removed by the screw conveyor (7). Both DJ passing liquids in the filter body are taken out all at once, resulting in furnace slag with a high liquid content. Further, even if pressurized air is blown into the lower furnace slag +ct+ of the disc filter, the filtrate remains there, so pressurized air cannot pass through it, and dehydration remains insufficient.

りこより、含液峯の低いｔｐ滓を得る方法である。In the present invention, when the PyIA step is completed and the unfiltered liquid is discharged by blowing compressed air through the residual liquid discharge pipe (2), a check valve is attached to the end of the filter body to draw out the P liquid that remains inside the filter body. Completely extract the P liquid, or extract the F liquid by installing a P liquid pipe inside the filter body.
After sufficient dehydration of furnace slag using pressurized air, 1/C
This is a method of obtaining TP slag with a low liquid content by scraping off the TP slag and taking it out with a scraper conveyor.

ることができる。First method of the invention: Check valve method: During pressurized filtration, it is sealed, but when removing unfiltered liquid, a check valve is attached to the opening, and a float is attached to the filter body. Type reverse valve (11
) A practical example of T-installation will be explained. (Figure 3) Stop when the float-type reverse valve attached to the rotating filter reaches its lowest position. When filtration is completed, open the remaining liquid drain pipe (21 and TP liquid outlet + 81 ffi and blow pressurized air into it, and the unfiltered liquid will be discharged from the drain pipe (2), and the filtrate inside the filter body will be discharged from the P liquid outlet (8). Initially, while the unfiltered liquid level is above the float valve, the float (12) is in close contact with the upper surface of the valve due to the VC buoyancy, and is kept sealed by the seal parayoung (18). (Figure 4-1) When the unfiltered liquid level drops below the float valve, the float (12) descends and the valve opens (No. 4
Figure 2), all of the P liquid in the filter body is discharged from the tank together with the unfiltered liquid through the discharge pipe (2). Since pressurized air is blown during this time, the P slag on the surface of the filter remains as it is, and the furnace slag on the lower half of the filter can be sufficiently dehydrated as well as the upper half of the filter.

下端になる位置で停止し、操作する。The reverse valve attached to the end of the filter body may be of any type other than a float valve, such as a bellows type valve, as long as it does not prevent damage during operation.The second invention is a method of providing a p-liquid pipe inside the filter body. . (Fig. 5) The rotating filter body is stopped at a position where the tip of the p-liquid pipe (14) in the filter body becomes the lower end of the fang, and then operated.

。By opening the residual liquid discharge pipe (2) and the furnace liquid outlet (8) and blowing pressurized air, the unfiltered liquid will be removed from the discharge pipe (2), and all the filtrate inside the filter will be transferred to the P liquid pipe inside the filter body. (14) Toshi, P
It is collected in the liquid pipe (5) and discharged from the p-liquid outlet (8).

とができる。Because pressurized air is blown into the filter, even if the P liquid pipe (5) is located higher than the lower end of the filter body, the filtrate remains inside the P liquid pipe (14).
rises and is discharged. The P slag on the surface of the filter remains as it is, and the pressurized air passes through the P slag, so that it can be sufficiently dehydrated.
加圧気体は主として空気が用いられるが窒素や二酸化炭
