Description

[Detailed Description of the Invention] This invention relates to an improvement of a cake pressurizing device in a belt press. Conventionally, in order to obtain a highly dehydrated cake by compressing and dewatering a cake using a belt press, it is necessary to apply high pressure to the cake in a pressurizing zone. However, when high-pressure compression is applied, even if the cake has lost its fluidity, it is forced out and leaks from the sides of the cloth, and is pushed into the holes of the cloth.
The problem was that it was difficult to peel off from the cloth. This idea is
It is an object of the present invention to provide a device which can solve these conventional problems, which can prevent cake from leaking from the side of the cloth during high-pressure compression, and which can be easily peeled off.

Below, we will explain this idea based on the drawings.
As shown in the figure, the structure is such that a pair of upper and lower cloths 1 and 2 are freely runnable between a large number of parallel rolls, and a cake S is sandwiched between the pair of cloths 1 and 2.
In a belt press configured to pressurize and press, an auxiliary belt 3 made of a large number of strong thin wires made of metal or the like is provided on top of the upper surface of the lower cloth 2, and at least this auxiliary belt 3 This is the pressure-pressed part of the cake S, which runs in synchronization with the lower cloth 2. In addition, in order to form the auxiliary band 3, as shown in FIG.
Alternatively, as shown in Fig. 3, a long series of thin wires 3'' may be wrapped around each roll so as to be in contact with each roll in a spiral manner. When the thin wires 3'' of the auxiliary band 3 run spirally on each roll, they push the lower fabric 2 and cake S in one direction, so that the lead direction of the spiral is directed toward the center of the rolls. By doing so, it is effective to prevent the cake S from leaking from the sides of the cloths 1 and 2. Third
The figure is an explanatory illustration of the state in which the thin wire 3" is wound spirally to form an auxiliary band, and is drawn much more roughly than it actually is. Arrow A indicates the running direction of the thin wire 3". In the figure, a pair of left and right thin wires 3'' are wound so as to run toward the center of the roll 4. In addition, the reference numeral 5 in the figure is a peeling roll;
6 is a comb body for straightening the auxiliary band 3, and the peeling roll 5 has thin wires 3', 3'' of the auxiliary band 3.
A groove 7 having a width of 3 to 5 mm is provided.
Further, 8 indicates a scraper.

This device is constructed as described above, and therefore, the sludge supplied to the right end portion in FIG. At the periphery, it is pressed and squeezed by a pressing belt 10 while being held between the upper cloth 1 and
It is ejected to the left side of the aircraft. When squeezing this sludge, in this invention, the auxiliary belt 3 is provided on the lower cloth 2, so the sludge is moved to the side by the thin wires 3' and 3'' that are the elements of this auxiliary belt 3. Therefore, even if it is strongly pressed with the pressing belt 10, it can be prevented from leaking from the sides of the cloths 1 and 2 as in the conventional case. Since S is formed on the auxiliary band 3, when the auxiliary band 3 and the lower fabric 2 are separated at the cake discharge portion (the left end portion in Fig. 1), it is placed on the auxiliary band 3. Then, at the lower part of the peeling roller 5, the scraper 8 and the fine lines 3' of the auxiliary band 3 are removed.
3" is completely peeled off by separating from the groove 7. If the cake S has no viscosity and is difficult to form bridges during this peeling, the thin wire forming the auxiliary band 3 It is sufficient to keep the distances of 3' and 3'' close. Further, the cake attached to the upper cloth 1 is peeled off by the scraper 8.

In this way, this invention can prevent the side leakage of the cake that conventionally occurs when high-pressure is performed with a belt press, and also completely removes the cake, which can solve all the problems of the past. It is.
