Abstract

PURPOSE: To easily cover the lowering of filtration performance due to clogging of a filter cloth and to automatically control the filtration performance by automatically freely elevating a horizontal moving weir which is freely ascendable and descendable in slid contact with the upper end of an original solution vat. CONSTITUTION: When filtration performance is lowered, the returned quantity from an original solution vat 4 is increased to raise the level in a slurry feed drum 15. Then, a level indicating controller 30 detects the rise and outputs a signal to a controller for a motor 25 which is rotatable in both the forward and backward directions to rotate a motor 25 in the direction in which a moving weir 20 rises by the necessary quantity. As a result, the area of a filtration region is increased and filtration performance is also increased and the level in the slurry feed drum 15 is lowered and is maintained at the prescribed level. Since the filtration performance is thus automatically controlled, maintenance control of operation is made easy.

The filter cloth 3 from which the cake C has been removed is cleaned from the front surface and the back surface by a cleaning liquid sprayed from a cleaning pipe outside the drum and a slit 10 provided under the valve shoe 7 in order to prevent clogging. . However, as the filtering operation progresses over time, the filter cloth gradually becomes clogged, and the filtering capacity decreases. Conventionally, in order to assist the reduction of the filtering ability due to the clogging of the filter cloth, the filtering ability is maintained constant by increasing the number of rotations of the rotary drum 1. However, this method of increasing the number of rotations to keep the filtration capacity constant requires considerable operating experience, and increasing the number of rotations of the drive motor increases the required capacity of the motor and raises the equipment cost. It is also the cause.

With the lapse of time in the filtration operation, the filter cloth gradually becomes clogged, and the filtration capacity of the filter decreases.
If the flow rate of the undiluted solution slurry F supplied from the previous step and flowing into the slurry feed drum 15 is constant, the liquid level in the slurry feed drum 15 starts to rise due to the decrease in the filtering ability. When this state is reached, the raising and lowering means of the barrier plate is driven to slightly raise the movable barrier plate. Since the liquid level in the stock solution vat 4 also rises due to the rise of the dam plate, the filtration area A in which the rotary drum 1 is immersed is increased, and it is possible to cover the reduction of the filtration capacity due to the increased clogging of the filter cloth 3. At this time, the operator may adjust the elevating means while monitoring the liquid level gauge of the slurry feed drum, but preferably the slurry feed drum is provided with a liquid level indicator controller, and the output of this controller is adjusted. It is desirable to automatically adjust by controlling the lifting means by. According to this control method, even if the flow rate of the stock solution slurry F flowing into the slurry feed drum fluctuates, the filtration area A of the rotary drum 1 can be automatically increased or decreased to cope with the change.
