Since the moisture within m passes through the filter layer 3.3' and seeps into the drain channel 5.5' where the pressure is low, it is rapidly reduced to the surface of the filter layer 3.3'. After the predetermined butchering operation has been performed, the valve 11 is operated to bring the inside of the overflow tank 9 to atmospheric pressure, and the valves 22 and 21 are opened to drain excess unattached slurry S in the casting space 4 to the slurry supply pipe 6. ．． Flexible pipe 16. Valve 22. The slurry is returned into the slurry tank 11 via the valve 21 and the slurry return pipe 20 (see FIG. 3). Furthermore, if necessary, close the valve 22 after mud removal and operate the valve 11 to supply compressed air into the overflow tank 9 to repressurize the meat part from inside and uniformly reduce the moisture content of the unattached part. .

Subsequently, the inside of the steam separator 12 is brought into a negative pressure state, the valve 13' is closed, the valve 14' is operated, compressed air is supplied into the steam water separator 12', and the filter medium I! The remaining water in the drain 3' is caused to seep out to the boundary between the surface of the filter material layer 3/ and the meat part by applying pressure in the drainage channel 51, forming a water film.
The portion 2b of the pressure container 2 other than the molded product hanging portion is lowered and removed in sections, and the cast molded product 31 is adsorbed to the filtering material layer 3 and held suspended, as shown in FIG. Next, the molded product carrying cart 27 is moved below the suspended cast molded product 31, the table lifter 29 is turned on, and the mounting table 30 is brought close to the bottom surface of the spun molded product 31.

The water seeps out to the boundary to form a water film, and the cast molded product 31 naturally falls onto the mounting table 30. Finally, after lowering the table lifter 29, the molded product carrying cart 27 is retreated to the standby position shown by the two-dot chain line in FIG. 4 to obtain a hollow cast molded product 31 placed on the mounting table 30. At the same time, the portion 2b of the pressure container 2 other than the molded product hanging portion is raised one step, and the molded product hanging portion 2a and the other portion 2b are engaged and clamped in preparation for the next casting operation.
しかし、前記従来の排泥鋳込み成形方法には、次の如き
欠点があった。However, the conventional sludge casting method has the following drawbacks.
■ オーバーフロータンク９は、内部にオーバーフロー

低かった。Therefore, when the sludge casting T culm is repeated about 30 to 40 times, the deposited sludge blocks the inside of the overflow tank 9. Conventional methods for bundling require periodic cleaning in an overflow tank, resulting in low production efficiency.

していた。◎ It has been confirmed that the inking time can be shortened by increasing the pressure on the slurry supplied into the casting space 4. However, in the past, compressed air was supplied into the overflow tank 9 to add sludge, so the High Pressure Gas Control Law imposed restrictions on the structure of the overflow tank 9 and the pressure limits of the piping fittings. The pressurizing force is 15
The limit was about 'j/clI7, and it took a long time to attach the flesh.

In addition, drain channels having openings to the outside of the pressure container are formed at appropriate pitches inside each filter material layer, and one end of each is formed in the casting space. Casting in which the other ends of the slurry supply pipe and the air vent pipe are open to the outside of the pressure vessel! ! Fill the casting space with slurry by supplying the slurry with a predetermined head pressure to the slurry supply pipe using i@, and after blocking the air vent pipe, supply high-pressure slurry to the slurry supply pipe using a high-pressure pump. On the other hand, if necessary, after reducing the pressure in the drainage channel through the opening of the drainage channel and performing a thickening operation for a predetermined time, the unattached slurry in the casting space is discharged from the slurry supply pipe, and the slurry is discharged from the slurry supply pipe.

The inside of the casting space 4 is filled with the slurry supplied from the slurry supply pipe 6 into the casting space 4 using the low pressure pump 18 whose head pressure is adjusted to a predetermined head pressure in advance, and the three-way valve 11 provided at the other end of the air vent pipe 33 is operated. After closing the air vent pipe 33, the high-pressure pump 36 (for example, a medium-moving piston pump driven by a hydraulic cylinder) connected in parallel with the low-pressure pump 18 at the slurry supply/discharge S% position 35 is operated to close the slurry supply pipe. By supplying high-pressure slurry (e.g. 20 to 30 kl/cj) to 6, pressure is applied to the slurry filled in the casting space 4, and the inking operation is carried out for a predetermined time (e.g. 5 to 6 minutes). After that, the three-way valve 11 of the air vent pipe 33
is operated to supply atmospheric air (compressed air, if necessary) to the air vent pipe 33 and discharge excess unattached slurry in the casting space 4 from the slurry supply pipe 6.

肉厚み９１１を得るのに５分間で達成できた。The predetermined water head pressure of the low-pressure pump 18 of the slurry supply and discharge device 1135 is the pressure necessary to fill the casting space 4 with slurry without overflowing the slurry to the level of the valve 11 at one end of the air venting pipe 331 in the air venting pipe 33. This refers to the head pressure. Note that when the low-pressure pump 18 is operated to supply slurry into the casting space 4, the valve 19 is opened and the valve 31 provided on the discharge side of the high-pressure pump 36 is closed. Also, operate the high pressure pump 36 to empty the casting! When pressurizing the slurry in the pump 14, the valve 37 is opened and the valve 19 provided on the discharge side of the low pressure pump 18 is closed. Furthermore, when returning the surplus unattached slurry in the casting space 4 to the tank 11, the valve 1
9. When 37 is closed, valve 21 is opened together with 11 convex. - [Function 1] Sludge at a predetermined head pressure is supplied to the slurry supply pipe 6 to fill the casting space 4 with the slurry, so the slurry does not overflow from the upper end of the air vent pipe 33. The slurry filled in the casting space 4 is pressurized by supplying high-pressure slurry to the slurry supply pipe 6 using the high-pressure pump 36, so that the slurry is compressed by 1°, which is determined by the discharge pressure of the high-pressure pumps 3 and 6. In order to find out what kind of influence the pressurizing force of the slurry filled in the casting space 4 has on the time for metallization, the inventor tested the reduced pressure conditions in the drainage channel 5.5' under the same conditions.
The following results were obtained. In the conventional method, the compressed air pressure in the overflow tank 9 was reduced to 10 kq/cd.
In this case, it took 10 minutes to obtain a deposited thickness of 91n, whereas when the water head pressure of the high-pressure pump 36 in the method of the present invention was set to 30 kq/-, it took 5 minutes to obtain the same deposited thickness of 911. It was accomplished in minutes.

Using a casting device in which each other end of an air vent pipe is open, slurry at a predetermined head pressure is supplied to the slurry supply pipe to fill the casting space with slurry, and after the air vent pipe is blocked, the slurry is transferred to the slurry supply pipe. While supplying high-pressure slurry with a high-pressure pump, if necessary, reduce the pressure in the drainage channel through the opening of the drainage channel, and after performing the filling operation for a predetermined time, remove the unattached slurry in the casting space. After discharging the slurry from the slurry supply pipe and pressurizing the inside of the drainage channel of the filter material layer in a portion other than the hanging portion of the molded product to cause the residual water to seep out to the boundary with the thickened portion on the surface of the filter material layer, The filtering material layer is divided and removed, and the cast molded product is adsorbed and suspended by the filtering material layer of the molded product suspension section, which is previously depressurizing the inside of the drainage channel, and then the inside of the drainage channel is pressurized to remove the filtering material layer. A mud removal casting molding method characterized by lowering a cast molded product onto a mounting table while exuding residual water inside the molded product.
