Plate and frame filter press is a commonly used filtration equipment, which is widely used in various fields, such as chemical industry, environmental protection, food, etc. However, in the actual use process, sometimes there is a problem of clogged feed holes, which not only affects the filtration effect, but also may cause damage to the equipment. Therefore, it is of great significance to understand the reasons for the blockage of the feed hole of the plate and frame filter press and take corresponding prevention and solution measures to ensure the normal operation of the equipment.
1. The reason for the blockage of the feed hole.
1.Excessive suspended solids: When the feed of the plate and frame filter press contains a large amount of suspended solids, these suspended solids are easy to accumulate at the feed holes, resulting in clogging.
2.Particles are too large: If the particles in the feed are too large, they cannot pass through the feed hole smoothly, and it is also easy to cause blockage.
3.Excessive viscosity: When the feed contains highly viscous substances, these substances tend to adhere around the feed holes, resulting in clogging.
4.Too high temperature: If the feed temperature is too high, it may cause the material to coke or clog at the feed hole.
5.Design flaws: If the feed hole is not properly designed or too small, it can also lead to clogging.
6.Improper maintenance: If the equipment is not cleaned and maintained for a long time, it is easy to cause the feed hole to be blocked.
2. Prevention and resolution measures.
1.Control the quality of the feed: By controlling the quality of the feed and reducing the content of suspended solids, particles, viscosity and other substances, the blockage of the feed hole can be effectively prevented. For example, for materials with a large amount of suspended solids, a clarification or filtration process can be added before feeding; For high-viscosity materials, the viscosity can be reduced by lowering the temperature appropriately or adding diluent.
2.Adjust the size of the feed hole: according to the actual needs, adjust the size of the feed hole appropriately to adapt to the passing requirements of different materials.
3.Regular cleaning and maintenance: Regularly clean and maintain the plate and frame filter press, especially the impurities and accumulations around the feed hole, so as to keep the equipment clean and operational.
4.Strengthen equipment inspection: By strengthening the inspection and monitoring of equipment, timely find and solve problems such as feeding hole blockage, and ensure the stable operation of equipment.
5.Improve the quality of operators: strengthen the training and education of operators, improve their professional quality and operation skills, so that they can better grasp the operating characteristics and maintenance requirements of the equipment.
6.Application of automation technology: Through the application of automation technology, such as intelligent control system and advanced monitoring device, remote monitoring and automatic adjustment of equipment can be realized, and the automation level and operational stability of equipment can be improved.
To sum up, there are many reasons for the blockage of the feed hole of the plate and frame filter press, and the prevention and solution measures are also relatively diverse. In the actual use process, corresponding measures should be taken according to the specific situation to strengthen the maintenance and management of the equipment to ensure the normal operation and use of the equipment. At the same time, we should also actively explore and research new technologies and methods to continuously improve the performance and reliability of equipment to meet the needs of different fields.
