Particles may clog the microscopic pores on the surface of ceramic filter plates or some fine particles may enter the internal pores of the ceramic filter plates, causing blockages that affect production capacity. Proper cleaning should be conducted.
Each cycle's backflush pressure serves to push out fine particles or dislodge particles adhering to the surface by reversing the flow through the ceramic filter.
2. Ensure both chemical and physical cleaning during shutdown for maintenance. First, ensure the cleaning time and quality for each session, achieving thorough cleanliness; secondly, avoid waiting until the ceramic filter plates are severely clogged before performing shutdown cleaning.
3. Choose the appropriate cleaning agent. Chemical cleaners undergo a chemical reaction with fine particles that are not easily flushed out, achieving the goal of particle refinement. This is then combined with a recirculating backflush to dislodge the fine particles. Different chemical cleaners can be selected for different slurry types, with the purpose of refining the particles.
4. Select ultrasonic equipment rationally based on the characteristics of different slurry types. Physical cleaning employs ultrasonic cleaning, where the power source converts industrial frequency electrical energy into high-frequency electrical signals. These signals are then transmitted through high-frequency cables to the transducer. The ultrasonic transducer converts high-frequency electrical energy into powerful ultrasonic waves, which are emitted outward. These waves vibrate within the槽体water solution, generating strong shock waves that dislodge dirt from the surface of ceramic filter plates.
Due to the minimal attenuation of ultrasound in aqueous solutions, it effectively cleans the surfaces of objects immersed in liquid, including narrow slots and small holes. Physical cleaning of the ceramic filter plate surface is optimal at water solution temperatures between 20-50°C. During cleaning, the main shaft speed is reduced, and after a period, adjust the main shaft speed or use an automatic frequency-following ultrasonic device to ensure thorough cleaning at each point. For surfaces with sticky, heavy污物, a higher-frequency ultrasonic transducer can be employed.
