1. Preparation before operation.
1.Check whether the parts of the filter press are complete and intact, and whether there is wear, looseness, deformation or serious rust.
2.Check whether the hydraulic system of the filter press is normal, whether the oil pump, oil cylinder, oil circuit, etc. are working normally, and whether the oil pipe joints, seals, and oil level gauges are tightened.
3.Check whether the filter plate and filter frame of the filter press are in good condition, whether the filter cloth is damaged or blocked, and whether the filter plate, filter frame and filter cloth are placed correctly.
4.Check whether the surrounding environment of the filter press is clean, whether there are debris, garbage, etc.
5.Prepare the materials required for filtration pressing, and if you need to add medicine, you should prepare the liquid medicine in advance.
2. Steps.
1.Start the hydraulic system so that the filter press is on standby.
2.Add the material to the feed hopper of the filter press, start the feed pump, and start feeding. Pay attention to observe the feeding situation during the feeding process to prevent blockage.
3.When the material reaches about 80% of the capacity of the filter press, open the filter press switch and start pressing. During the compression process, pay attention to the reading of the pressure gauge to ensure that the pressure is stable.
4.After the compression is completed, the feed pump and feed valve are closed, the washing valve is opened, and the filter cake is washed. During the washing process, attention should be paid to controlling the flow rate of the washing liquid and the composition of the washing liquid.
5.After the washing is completed, open the discharge valve and start discharging. During the discharging process, it is necessary to pay attention to the condition of the material to prevent the filter cloth from being damaged or blocked.
6.After the discharge is completed, the filter plate and filter frame are cleaned to ensure that there is no residue in the next use. During the cleaning process, pay attention to protect the filter plate, filter frame and filter cloth.
7.After the cleaning is complete, the hydraulic system is turned off and the filter press operation is ended.
3. Precautions.
1.During the process of filter pressing, the cleanliness of the hydraulic system should be maintained to prevent impurities from entering the oil circuit.
2.During the operation, pay close attention to the reading of the pressure gauge, and deal with it in time if any abnormality is found.
3.If the filter cloth is found to be damaged or clogged during use, it should be replaced or cleaned in time.
4.When carrying out the filter press operation, the safety of the surrounding environment should be ensured to prevent accidents.
