Plate and frame filter press is a kind of solid-liquid separation equipment widely used in industrial fields, and its working principle is to squeeze the filter cake by applying pressure, so as to achieve the purpose of dewatering, filtration and pressing. However, in practice, in order to pursue higher filtration efficiency or production efficiency, some companies will excessively increase the pressure of the plate and frame filter press, which will not only accelerate equipment wear and reduce service life, but also may cause safety accidents. This article will analyze in detail the damage that can be caused by over-pressurization of the plate and frame filter press.
1. The equipment is damaged.
1.The filter plate of the plate and frame filter press is the main component to withstand pressure, and excessive pressure will cause the filter plate to be deformed or damaged by excessive pressure in a short time, thus affecting the sealing and filtration effect of the equipment.
2.The filter cloth is used to support the filter cake, and excessive pressure will cause the filter cloth to stretch and tear, affecting its filtration performance and service life.
3.The hydraulic system is the power of the plate and frame filter press, and excessive pressure will overload the hydraulic system, causing problems such as increased oil temperature and oil leakage, which may lead to damage to the hydraulic components in serious cases.
2. Safety accidents.
1.Excessive pressurization will cause the pressure inside the plate and frame filter press to rise rapidly, and once it reaches or exceeds the bearing limit of the equipment, it may lead to equipment or rupture, personnel and property damage.
2.In the process of over-pressurization, if there is a leak or abnormal situation in the equipment, the operator fails to detect or deal with it in time, which may cause a more serious accident.
3. Environmental pollution.
1.Excessive pressure will loosen the filter cake inside the plate and frame filter press, resulting in a decrease in the quality of the filtrate, containing more fine particles and suspended solids, and causing certain pollution to the environment.
2.If there is a leak or accident during the operation of the plate and frame filter press, it will not only damage the equipment itself, but also cause serious pollution to the surrounding environment.
In summary, over-pressurizing a plate-and-frame filter press can cause serious damage to the equipment itself, the operator, and the environment. In order to ensure the safe and stable operation of the equipment, enterprises should use and maintain the plate and frame filter press in strict accordance with the design requirements and operation specifications to avoid dangerous operations such as overpressurization. At the same time, the equipment parts that have been worn or damaged should be replaced or repaired in time to ensure the normal operation and use of the equipment. Only in this way can we give full play to the advantages of plate and frame filter press and improve the production efficiency and economic benefits of enterprises.
