Retractable CIP rotary spray nozzle
Retractable CIP nozzles allow the nozzle tip to sit flush against the inside of the equipment being cleaned (reactors, spray drying chambers, cyclones, fluidized beds, storage tanks, pipes, etc.) when not in use. Retracting during operation does not disrupt the process and eliminates product entrapment. During operation, water is pumped under pressure to the nozzle, which forces the nozzle tip into the correct position for cleaning the equipment. Once the water supply stops, the nozzle tip automatically retracts to its starting position.
Working Principle
The working principle of CIP nozzles depends primarily on their unique design and the flow pattern of the cleaning fluid. In a CIP system, the cleaning fluid is delivered to the equipment being cleaned via pipes and pumps, where it is evenly sprayed out by the nozzles. The nozzles typically feature a rotating design, which allows them to cover a larger cleaning area and form a dense, mesh-like pattern, ensuring that the cleaning fluid fully contacts the internal surfaces of the equipment. Furthermore, the nozzles can be adjusted as needed to suit different cleaning requirements and equipment characteristics.
Maintenance Recommendations
1. Regularly Check Nozzle Condition
Cleaning nozzles are prone to wear and clogging during use, especially when handling cleaning fluids containing particulate matter. Therefore, regularly inspect the nozzle's spray holes for foreign matter, changes in the spray angle, and cracks or corrosion.
2. Correct Method for Cleaning Nozzles
Disassembly and Cleaning: Use a soft brush or compressed air to remove dirt and particles from the nozzle interior. Avoid using sharp tools to prevent damage to the nozzle surface.
Chemical Cleaning: For stubborn stains that are difficult to remove, use a suitable chemical cleaner, but ensure that the cleaner does not corrode the nozzle material.
3. Measures to Prevent Clogging
Filters: Installing a filter in the cleaning system can effectively prevent particles from entering the nozzle and reduce the risk of clogging.
Regularly Change Cleaning Fluid: Cleaning fluid that has been used for a long time may accumulate impurities, affecting the nozzle's proper function.
4. Nozzle Storage Precautions
Unused nozzles should be stored in a dry, well-ventilated environment, avoiding exposure to high temperatures, high humidity, or corrosive gases. In addition, make sure the inside of the nozzle is completely dry before storage to prevent residual liquid from causing corrosion or scaling.
