On the other hand, the filtrate passes through the vacuum suction box 4 and the sinterable tube 14
It is taken out of the machine by In this way, the vacuum suction box 4 that has finished vacuum suction is released from the vacuum suction at its end (pulp operation, not shown), and
After being lowered by the hydraulic jack 7, it is moved back to the extreme end by the pneumatic jack 6 in preparation for the next suction. That is, in the device according to the present invention, since the filter cloth, the filtrate box, and the vacuum suction box 4 operate in synchronization, there is no sliding resistance, and when the vacuum suction box 4 moves back after stopping the suction, there is no sliding resistance. is reliably dissociated from the filtrate box 2, so
Since there is no sliding resistance and the vacuum suction box 4 is lightweight, quick recovery is possible. Therefore, it takes only a short time to interrupt the suction of the stock solution on the filter cloth that is continuously running. Note that it is also possible to eliminate this interruption; for example, as shown in Figure 3, two vacuum suction boxes are installed, and while one is suctioning, the other is moved back and forth, and the pub switching operation is performed. By repeating this process alternately, continuous filtration work can be performed starting from oranges by constantly suctioning.
