DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an over-dehydration machine with a squeezer that, after straining and squeezing the slurry, injects the slurry between the pressed cake and the cloth and carrying out the straining and squeezing again. be.

The curve OABCD in FIG. 1 is the relationship between liquid volume and time when slurry is dehydrated using a conventional over-dehydrator with compression. The initial stage is the dehydration rate (liquid volume/time)
is large, but becomes smaller after passing point A. This is because as the baking progresses, the cake becomes thicker and harder to spread. Point B is the starting point for squeezing, and when squeezing begins, the dehydration rate is initially high, but after point C, it decreases. This is because the cake becomes denser as the pressing progresses. Therefore, if a thicker cake is to be obtained, the dewatering time will be very long and the dewatering rate will be low. If over-pressing and squeezing are done in a short time, for example, over-squeezing time can be reduced by 1/2.
If it is set to 2, the curve OAE in Fig. 1 will be obtained, and the dewatering speed will be improved, but the cake will be difficult to separate from the cloth because the thickness of the cake will be small.

また一定時間内における脱水サイクル数が多く

In addition, since the number of dewatering cycles within a certain period of time increases, the time required for closing, opening, cake peeling, cloth washing, etc. increases in proportion to the number of dewatering cycles, making it impossible to expect an improvement in the dewatering speed.

An object of the present invention is to provide an over-dehydrator with a press that has a high dewatering speed and can produce a cake with a large thickness.

That is, as is clear from the side view of FIG. 2 and the cross-sectional view of FIG.
In addition, on the inner surface of the rear plate 4', a diaphragm 3 is stacked between the cloth 2' and the periphery of the diaphragm 3 is abutted against each other, and a chamber 5 is interposed in the middle to fix the diaphragm 3 in an openable manner. Slurry injection tubes 1, 1' leading to the chamber 5 are provided with their respective ends formed at bent ends, one 1' facing the front cloth 2 and the other 1' facing the rear cloth 2'; 4 is a liquid discharge pipe 6 that leads to the back side of the front cloth 2, and the rear plate 4' is a liquid discharge pipe 6' that leads to the back side of the rear cloth 2', and a pressurized water pipe that runs between the diaphragm 3 and the inner surface of the rear plate 4'. It is configured by disposing an injection pipe 8. Reference numerals 7 and 7' designate injection valves interposed in the slurry injection pipes 1 and 1'.

Thus, the device of the invention is particularly suitable for rear plate 4'.
A diaphragm 3 is interposed between the diaphragm 3 and the rear cloth 2', and the cake is compressed and grown in stages by the pressure of the diaphragm and the injected slurry. They are used in the order shown in FIG. 3 to 7 show the slurry injection pipe 1

At point A in Figure 1, when the dewatering speed has decreased, the slurry injection valves 7 and 7' are closed, and pressurized water (10 to 20 kg/
cm 2 ) is injected into the compression chamber 9 from the pressure water injection pipe 8 as shown in FIG. The excess cake in the chamber 5 is compressed and dehydrated by the diaphragm 3, and the thickness is reduced to form a compressed cake 10.

At point E in FIG. 1 when the dewatering speed has decreased, the pressure in the compression chamber 9 is reduced to 0 or close to it, the slurry injection valve 7 is opened, and the slurry 11 is injected into the chamber 5 from the slurry injection pipe 1. Slurry 11
The outlet of the slurry injection tube 1 faces the fabric 2 so that the slurry does not break the compressed cake 10 and go towards the fabric 2'.

Therefore, the injected slurry 11 pushes the pressed cake 10 towards the pressing chamber 9, and the entire surface of the cloth 2 is filled with the slurry 11 as shown in FIG. Immediately after the slurry 11 fills the chamber 5 as shown in FIG. 5, the slurry injection valve 7 is closed, the slurry injection valve 7' is opened, and the slurry 12 is injected. The discharge port of the slurry injection pipe 1' faces the cloth 2' so that the slurry 12 does not come into contact with the slurry 11. Therefore, the pressure of the slurry 12 increases as the slurry 1 passes through the compressed cake 10.
1, the slurry 11 is filtered through the cloth 2 and its volume is reduced, resulting in a filter cake 11' (see FIG. 6).

As the pressed cake 10 moves to the left, the slurry 12 enters between the pressed cake 10 and the cloth 2' as shown in FIG. The slurry 12 is the cloth 2'
is passed through to form a supercake 12'.
At point F in FIG. 1, where the overspeed has decreased, the slurry injection valve 7' is closed and pressurized water (10 to 20 kg/cm 2 ) is injected into the compression chamber 9 from the pressure water injection pipe 8.
The overcake 11' is caused by diaphragm 3 as shown in
(FIG. 6) is compressed to become a compressed cake 13 whose thickness is reduced. Similarly, overcake 12' (Figure 6)
becomes a compressed cake 14 with a reduced thickness.

Comparing dehydration end points G and D at the same time, G clearly has a larger liquid volume. Therefore, the super dehydrator with a press according to the present invention has a higher dehydration speed and can produce a pressed cake with a larger thickness than the conventional super dehydrator with a press.
