In this embodiment, since a drive device for moving the furnace cloth up and down for each group is provided, the door plate can be opened and closed and the furnace cloth can be moved up and down for each group smoothly and reliably.

In addition, the driving force required to move the cloth up and down can be reduced, and the stability and mechanical strength are extremely improved.

Furthermore, as in the past (as the number of door panels increases, the drive shaft inevitably becomes longer and there is no longer a limit to the number of door panels), we increased the number of door panels by 9 to the extent that other conditions allow, improving the filter press's capacity. can be achieved.

Therefore, even if there is a group of individual door panels, only the opening distance of the group with the longest opening distance needs to be set as the overall opening distance, so compared to the conventional method,
The opening distance is very small.

On the other hand, if a conventional filter press consisting of one set is divided into 1, for example, 5 parts and a driving device etc. is provided as in the present invention, the opening distance will be reduced to one-fifth, and the driving force of the driving device will be reduced to one-fifth. It only takes one-fifth of the cost, and the drive stability and mechanical strength of the device are five times or more compared to the conventional case of one.

In this example, the furnace plate and the movable plate were moved by a transfer body on a drive band, but the movement is not limited to this, and it may also be performed manually using a pan or the like. Any device that moves the filtration surface of the furnace cloth up and down, such as one that runs and rotates the furnace cloth around the furnace plate, and that applies one or two furnace cloths to one side of a door plate. good.

Effects of the Invention As described in detail in the above embodiments, according to the present invention, the drive shaft and its drive source for sequentially moving up and down the cloth of the furnace plate for each set are connected to the drive shaft and drive source of the other set. Since it can be driven individually and independently from each other, the opening and closing of each set of Mukuhi door boards and the up and down movement of the oki cloth can be performed smoothly and reliably, and the driving force of the drive source is considerably greater than that of conventional ones. It is possible to use a small one (1) The drive is stable, the mechanical strength of the device is improved, and as the number of door plates increases, a drive shaft and drive source with a length, thickness, and strength corresponding to the number of furnace plates are provided. This has the effect of easily and reliably improving the throughput of the filter press.

Furthermore, it is sufficient to set the space for opening the door frame of the entire filter press to the longest opening distance of the door frame opening distances of each set of door plates, and since the opening distance becomes considerably small, the amount of processing per floor area is reduced. It has the effect of increasing abilities.
