Plate and frame filter press is a kind of filtration equipment widely used in industrial production, which can separate solid impurities in the liquid through the filter medium, and is widely used in chemical, environmental protection, food, pharmaceutical and other fields. In the process of using the plate and frame filter press, it is necessary to pay attention to some operation details and safety matters to ensure the normal operation of the equipment and the safety of production.
1. Preparation before operation.
1.Check for obstructions around the equipment and make sure there is enough space around the equipment for operation and maintenance.
2.Check whether the power connection is normal and meets the requirements of the device.
3.Check whether the hydraulic system is normal, whether the hydraulic oil is sufficient, and whether the oil quality is clean.
4.Check whether the filter plate and filter cloth are in good condition, and replace them in time if they are damaged or blocked.
5.Check whether the instrumentation and valves of the equipment are sensitive and reliable.
Second, the operation process.
1.Before starting the equipment, the power of the hydraulic system should be turned on and the solenoid valve should be switched to the working state.
2.According to the requirements of the production process, place the filter plate and filter cloth in the equipment, and ensure that the filter plate is placed neatly and flatly.
3.Start the oil pump of the hydraulic system to adjust the pressure and flow, so that the hydraulic oil enters between the filter plate and the filter cloth to form a certain pressure difference.
4.Open the feed valve of the equipment, introduce the liquid to be filtered into the equipment, pay attention to the instrumentation and valves of the equipment, and ensure that the liquid flow and pressure are within the normal range.
5.Wait for the solid impurities in the liquid to be trapped on the surface of the filter cloth to form a filter cake.
6.Close the feed valve, open the washing valve, and wash the filter cake.
7.Close the washing valve, open the blowing valve, and blow dry the filter cake.
8.Close the blowing valve, turn on the oil pump of the hydraulic system, and separate the filter plate and filter cloth.
9.Open the discharge valve of the equipment and discharge the filter cake from the equipment.
10.Repeat the above operations until the production process completes the requirements.
3. Safety precautions.
1.During operation, care should be taken to avoid touching the moving parts of the equipment to avoid accidents.
2.During the operation of the equipment, the operating parameters and status of the equipment shall not be changed at will.
3.When the equipment is maintained and overhauled, the power supply and the power supply of the hydraulic system should be turned off first to ensure that the equipment is in a safe state.
4.In the process of use, if there is an abnormal situation, it should be stopped immediately for inspection, and the fault can be eliminated before continuing to use.
5.During the operation, the site should be kept clean and hygienic to avoid pollution to the environment.
Fourth, maintenance and maintenance.
1.Regularly check whether the instrumentation, valves, hydraulic systems and other components of the equipment are working normally, and repair and replace them in time if there are problems.
2.Clean the filter cloth and filter plate of the equipment regularly to avoid clogging and wear.
3.Regularly check the oil quality and oil quantity of the equipment, and replace the hydraulic oil in time.
4.When the equipment is not in use, the equipment should be cleaned and maintained regularly to keep the equipment in good condition.
In short, the correct operation of the plate and frame filter press and pay attention to safety matters are important guarantees to ensure production safety and normal operation of equipment. In actual operation, it is necessary to strictly follow the operating procedures, find problems and deal with them in a timely manner, and do a good job in daily maintenance and maintenance to ensure the normal progress of production.
