Plate and frame filter press is an important equipment in industrial production, mainly used for solid-liquid separation and liquid purification. The workflow consists of the following steps:
1. Preparation stage.
Before the plate-and-frame filter press can start working, a series of preparations need to be carried out. First of all, it is necessary to check whether the various parts of the plate and frame filter press are intact, especially the plate frame and filter cloth, to ensure that there is no damage or blockage. At the same time, the equipment needs to be cleaned to ensure the cleanliness of its interior. In addition, it is necessary to check that the hydraulic system is working properly and that all valves are in the correct position.
Second, the feeding stage.
After the preparation is complete, the feeding can begin. The feeding stage of the plate and frame filter press is to add the materials that need to be processed to the equipment. It should be noted that the flow rate should be controlled when feeding the material to avoid overflow caused by too large flow or idling of the equipment due to too small flow. At the same time, it is also necessary to pay attention to the temperature and viscosity of the material to ensure the normal operation of the equipment.
Third, the pressing stage.
After the feeding is completed, the plate and frame filter press enters the pressing stage. At this stage, the hydraulic system of the plate-and-frame filter press starts to work to pressurize the material. As the pressure increases, the liquid part of the material is gradually extruded and worn through the filter cloth. At the same time, the moisture content of the filter cake is gradually decreasing. At this stage, it is necessary to pay close attention to the changes in pressure and flow, as well as parameters such as the moisture content of the filter cake, to ensure the proper operation of the equipment and the best separation results.
Fourth, the unloading stage.
When the pressing stage is completed, the plate-and-frame filter press enters the discharge stage. At this stage, the cake is removed from the plant and can be further processed or utilized. It should be noted that safety should be paid attention to when unloading to avoid accidents caused by improper operation. At the same time, it is also necessary to clean up the residue inside the equipment in time to maintain good working condition.
5. Cleaning and maintenance stage.
After the discharge is completed, the plate and frame filter press needs to be cleaned and maintained. The purpose of cleaning is to remove residues from the inside of the equipment and ensure the cleanliness of the equipment. The purpose of maintenance is to keep the equipment in good working condition and prolong the service life of the equipment. During cleaning and maintenance, care needs to be taken to avoid damaging the internal parts of the equipment, especially the filter cloth and plate frame.
To sum up, the workflow of the plate and frame filter press includes steps such as preparation stage, feeding stage, pressing stage, discharging stage, cleaning and maintenance stage. In practice, it is necessary to select appropriate process parameters according to the properties and separation requirements of different materials to ensure the normal operation of the equipment and obtain the best separation effect. At the same time, it is also necessary to strengthen the maintenance and maintenance of the equipment, find and solve potential problems in time, so as to ensure the long-term stable operation of the equipment.
