Reasons Why the Filter Press Does Not Discharge Filtrate

Reasons Why the Filter Press Does Not Discharge Filtrate

There are various problems in the use of filter presses. One of the common problems is the failure to discharge filtrate. There are many reasons for this problem, which need to be analyzed and corresponding measures taken according to the actual situation. The following will introduce the reasons and solutions for the failure of filter presses to discharge filtrate.

Recessed Plate Filter Press

Introduction of Recessed Plate filter press A recessed plate filter press is batch-operated filtration equipment that is used for solid-liquid separation of various suspensions,...

• The feed valve is not open or blocked: the pump is running normally, but no material enters the filter press.
• The filter cloth is blocked: the filter cloth is the main filtering component of the filter press. If the filter cloth is blocked, the liquid cannot pass through the filter cloth, resulting in no water. The reasons for the filter cloth blockage may be the quality of the filter cloth, the filter cloth’s pore size is too small, the filter cloth is improperly installed, etc.
• Pipeline blockage: If the outlet pipe of the filter press is blocked, the filtrate will not be discharged. The reasons for the pipe blockage may be the deposition of impurities in the pipe, unreasonable pipe design, improper pipe installation, etc.
• Pump failure: The filter press is usually equipped with a water pump. If the water pump fails, it will directly affect the filtrate output of the filter press. The reasons for the water pump failure may be water pump wear, water pump electrical failure, improper water pump installation, etc.
• Hydraulic system failure: Some filter presses use hydraulic systems for pressurization. If the hydraulic system fails, it will cause failure to pressurize normally, thus affecting water output. The causes of hydraulic system failure may be wear of hydraulic components, contamination of hydraulic oil, unreasonable design of the hydraulic system, etc.

Solution

1. Check the feed valve: Check the feed valve status and whether materials or impurities block the inside.
2. Check the pipeline: Check whether the outlet pipeline is unobstructed. If there are impurities deposited in the pipeline, it should be cleaned in time. Check whether the design and installation of the pipeline are reasonable to ensure that there are no dead corners and protrusions in the pipeline.
3. Check the water pump: Check whether the water pump is working properly. If the water pump malfunctions, it should be promptly repaired or replaced. Verify that the pump is installed correctly, and ensure the connection between the pump and the motor is secure and reliable.
4. Check the hydraulic system: Check whether the hydraulic system is working properly. If the hydraulic system malfunctions, the faulty components should be repaired or replaced promptly. Inspect the hydraulic oil for cleanliness and proper oil level to ensure the system operates smoothly.

Preventive Measures

• Regular cleaning and maintenance: Clean and maintain the filter press regularly, remove impurities and sediments in the filter cloth, pipes, and pumps, and ensure the smooth operation of the equipment.
• Choose high-quality accessories: Choose reliable filter cloth, pipes, pumps, and other accessories to avoid blockages and failures caused by quality problems.
• Proper Operation: Operate the filter press strictly according to the established procedures to prevent equipment damage and water-related issues resulting from improper use.
• Regular inspection: Regularly inspect the various components of the filter press to promptly discover and solve potential problems and ensure the normal operation and service life of the equipment.

Conclusion

There may be many reasons why the filter press does not produce water, including filter cloth blockage, pipe blockage, pump failure, and hydraulic system failure. In order to solve this problem, we need to inspect and repair according to the specific situation. It is also very important to take preventive measures, including regular cleaning and maintenance, reasonable operation, and regular inspection. With proper use and regular maintenance, the filter press can operate efficiently and reliably, ensuring long service life and consistent support for industrial production.
