Precautions for New Cloth

- Sep 10, 2019-

Today, I will show you some notes on the new filter cloth, hoping it will be helpful to you.

1. The pressing contact parts of the filter plates around the filter cloth shall be smooth and free from wrinkles to avoid damage or mud leakage caused by squeezing the filter cloth by the filter plates.

2. To avoid damage to filter cloth or mud leakage caused by overlong tail of retaining ring which may extend into the pressed part of filter plate, the short tail shall be cut off.

3. During installation, attention should be paid to the fact that there are no foreign matters or large sludge particles between the filter cloth and the filter plate. Large sludge particles or foreign matters may cause damage to the filter plate or filter cloth when the plate is closed.

4. Attention should be paid to the front and back surfaces (for mud surface and non-mud surface) when installing the filter cloth. In general, the cloth surface (polished surface) of the filter cloth is opposite to mud without special requirements.  Otherwise, the wrong installation will make the filter cloth easy to block and the filtering efficiency is low.

5. When installing the filter cloth, do not lock the filter cloth too tightly with the retaining ring, otherwise the sludge remaining in the filter cloth at the pressing contact part of the filter plate will not be automatically cleaned and removed.

6. The spare filter cloth should be stored in a cool and dry place. It is recommended to use dark shade cloth to protect it from ultraviolet radiation and prevent the aging of the filter cloth material.

7. Before installing the filter cloth, it is necessary to install the supporting filter cloth. Its function is to reduce the abrasion of the salient points on the surface of the filter plate that may be rubbed due to the rapid downward separation of the filter cloth by the filter cake under the action of gravity to a lower level when discharging mud, so as to protect the filter cloth, prolong the service life of the filter cloth and improve the filtering effect. The installation method of the supporting filter cloth can refer to the installation method of box filter cloth, which is roughly the same.
