As the core filter medium, the performance of the filter cloth of the filter press is directly related to the filtration effect of the filter press. However, during use, the filter cloth of the vertical filter press often has a problem with sticking cloth, which not only affects the filtration effect, but also increases the difficulty of cleaning and maintenance. This article will conduct an in-depth analysis of the causes of vertical filter press cloth sticking cloth, and take corresponding solutions.
There are many reasons why vertical filter press cloth sticks to cloth. First of all, too high a feed temperature can lead to the occurrence of cloth sticking. Too high a feed temperature will cause the moisture in the material to evaporate too quickly, so that the solid particles in the material will form a bond on the surface of the filter cloth. Secondly, too high a feed concentration can also lead to cloth sticking. Highly concentrated materials tend to form a filter cake on the surface of the filter cloth, and when the filter cake dries, it will form a bond on the surface of the filter cloth. In addition, the material and processing process of the filter cloth will also affect its anti-sticking properties. Some materials of filter cloth are prone to chemical reaction with the material, resulting in bonding.
In order to solve the problem of vertical filter press cloth sticking, the following measures can be taken:
1.Control the feed temperature. According to the characteristics of the material and the design requirements of the filter press, the feeding temperature should be reasonably controlled to avoid the phenomenon of sticking cloth caused by excessive temperature.
2.Reduce feed concentration. Reduce the feed concentration appropriately and avoid the formation of too thick filter cake on the surface of the filter cloth to reduce the possibility of sticking to the cloth.
3.Choose the right filter cloth material. Choose a filter cloth material with good anti-sticking to avoid chemical reaction with the material, so as to reduce the occurrence of sticking phenomenon.
4.Improve the filter cloth processing process. Improve the weaving and processing quality of the filter cloth, enhance its anti-sticking, and thus extend the service life of the filter cloth.
5.Regular cleaning and maintenance. Clean and maintain the filter cloth in time to prevent material residue and accumulation, so as to reduce the occurrence of sticky cloth.
6.Optimize the operating parameters of the filter press. According to the characteristics of the material and the design requirements of the filter press, the operating parameters of the filter press, such as pressure, flow, etc., are reasonably adjusted to improve the filtration effect and reduce the occurrence of sticking cloth.
To sum up, the problem of vertical filter press cloth sticking cloth is a complex problem that needs to be analyzed and solved from multiple aspects. By controlling the feed temperature, reducing the feed concentration, selecting the appropriate filter cloth material, improving the filter cloth processing technology, regular cleaning and maintenance, and optimizing the operating parameters of the filter press, the problem of vertical filter press cloth sticking can be effectively solved, and the filtration effect and service life of the filter press can be improved.
