Title:
フィルタープレスにおけるろ布収縮検知方法並びに検知装置
Document Type and Number:
Japanese Patent JP5585890
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a filter cloth contraction detection method and detection device in a filter press, capable of detecting contraction of a filter cloth and easily adjusting tension of the filter cloth.SOLUTION: In the filter press for freely elevating and lowering a filter cloth 5, the moving time T when a prescribed part of the filter cloth 5 moves from an elevation limit to a prescribed position is measured, an alarm is issued when being equal to or longer than set time T0, and calculation is automatically performed when the filter cloth 5 is elevated and lowered. Since the need of having a worker periodically measure the contraction amount of the filter cloth 5 by manual work is eliminated and the tension of a driving chain 27 and the exchange of the filter cloth 5 are detected before the performance and function of the filter press are affected, maintenance is facilitated. Also, from the moving time T of the filter cloth 5, the appropriate exchange time of the filter cloth 5 is predicted.
