Ultrasonic belt cleaners are labor-saving appliances, which collect particles that come off of the furnace belt so that these contaminants can be safely drained away. Ultrasonic cleaners combine ultrasound technology with a sanitizing solvent, which thoroughly scours the furnace belt to remove all traces of contamination. Ultrasonic technology is very important for furnace belt maintenance, as it can deliver incredibly precise and efficient cleaning capabilities. Preserving the cleanliness of a furnace belt is vital when it comes to prolonging the lifespan of a furnace, and ultrasonic cleaning has proven to be the best solution to long-term furnace belt care.
Principles Behind Ultrasonic Cleaning Technology
An ultrasonic belt cleaner uses carefully positioned transducers to emit sound waves into the cleaning tank, which contains a purifying solvent. A transducer is an instrument that transforms one form of energy into another. In this case, transducers produce ultrasonic waves that cause the solvent to vibrate at ultrasonic frequencies, generating bubbles that implode around the sections of the belt in need of sanitation.
These bubbles are specifically formed by extremely rapid pressure changes within the fluid, caused by the ultrasonic waves. These waves travel through the tank, causing the liquid to compress and expand. As a result, an immense amount of microscopic bubbles are left behind, which implode and dislodge impurities from the furnace belt.
Process of Cavitation: A Microscopic Brush
Water can only exist in a liquid state above a minimum pressure (the threshold of cavitation). When pressure decreases below this threshold, water becomes a gas and bubbles form. Then, when the pressure increases, gas bubbles collapse again. This process of creating rapid formations and destructive prostrations of minute bubbles in liquid is known as cavitation, and it is responsible for the scrubbing action that removes contaminants from the belt. Cavitation will transpire throughout the cleaning solvent if the energy intensity is adequate. It will also expedite chemical reactions and the rate at which surface films are dissolved.
As the ultrasonic frequencies increase, the number of microscopic bubbles also increases; however, the respective energy that is released from each bubble simultaneously decreases. This means that higher frequencies are ideal for small particle removal, without damaging the belt. The vast amount of imploding bubbles creates a highly effective scrubbing action on both the exposed and the hidden areas of the belt that are immersed within the cleaning solution.
Advantages of Ultrasonic Belt Cleaning:
Simply put, the advantages of using ultrasonic belt cleaning technology revolve around precision, speed, and consistency. Ultrasonic energy is able to infiltrate obscure regions of the belt, which means that all areas of the belt will be comprehensively cleansed. Furthermore, integrating the belt cleaner into the furnace is straight-forward. The ultrasonic cleaning is inline, so the belt travels directly through the tank and there is no need to disassemble the belt from the furnace. The belt can pass through the tank whenever necessary. This means superior cleanliness, and will guarantee a better working environment for the furnace.
Ultrasonic cleaning also works faster than any other conventional cleaning procedure in the elimination of contaminants. Due to the efficiency of ultrasonic antisepsis, labor-saving and sanitization benefits indicate that ultrasonic technology is the best economical method for cleaning furnace belts. When ultrasonic technology is used, there is far less risk of products getting contaminated, which improves yield. Furthermore, there is less belt abrasion, which means that the belt will have a longer lifespan. Lastly, there¡¯s no need to ever replace any brushes.
Ultrasonic technology offers incomparable cleaning consistency throughout the entire belt. Using a steel brush as a tool for cleaning the belt, on the other hand, can often be time-consuming, imprecise, and inconsistent. A steel brush uses steel wire bristles to clean the surface area around the belt, and due to its abrasive nature and inability to reach abstruse regions of the belt, it cannot reach the level of cleanliness that an ultrasonic belt cleaner can easily achieve.
Equipment Maintenance and Belt Cleaning Guidelines
- Keep the belt speed under 150 mm/min while cleaning.
- Use distilled water instead of tap water as the solvent. Tap water can contain impurities, and distilled water that has been degassed allows for more even distribution of cavitations.
- Always monitor the quality of the solvent.
- After use, clean out the rinse tanks.
- After use, change the filters.
