Description & Spare Parts

When the CIP nozzle is in its retracted (closed) position, the head of the nozzle rod assembly is flush with the nozzle housing. The O-rings in the nozzle rod ensures that foreign material cannot penetrate into the housing while the nozzle is in both open and closed positions. See reference drawings figure 2.

Figure 3 (open position)

When the nozzle is in its extended (opened) position, the nozzle head inside the nozzle weld pad is out of the nozzle housing by 1-5/8". See Fig 3.

Function

The nozzle is opened and closed by means of a pneumatic cylinder mounted on the back of the nozzle. When the nozzle is to be extended (opened) the pneumatic cylinder is activated pushing the complete nozzle rod assembly out of the nozzle housing and into the chamber to be cleaned, exposing the live ring spinner.

While in the extended position, the live spinner ring is free of the housing and rotates as the cleaning liquid is forced through it. Because of its design and rotation while in operation, it disperses the liquid over the desired area of the equipment to be cleaned.

Positioning of CIP Nozzle

NOTE: The information shown in this section is for general positioning requirements only, some specific applications may have different requirements. Contact Niro engineering for specific applications.

Ducting:

Horizontal Duct

• CIP nozzles should the mounted 45° from horizontal and alternate from one side of the duct to the other. (See Figure 4.)
• Whenever possible the feed header should be above the nozzles. (See Figure4.) Feed header should also be sloped for draining.
• Space CIP nozzles based on table below.

Figure 4

Vertical Duct

• Because CIP solution can cascade down the surface of a vertical duct, the CIP nozzles only need to be located near the top of vertical ducts. (See Figure 5.)
• The number of nozzles required for vertical ducts is shown on the table below.
• Nozzle feed header must be below the nozzles. Feed header must also slope for draining. (See Figure 5.)

The number of nozzles required for vertical ducts

Other Considerations:

• Additional nozzles will be required on elbows.
• In both horizontal and vertical ducts, additional nozzles will be required near isolation plates, air dampers, manways and other ports to ensure cleaning.
• Because of the internal geometry of the CIP nozzle, some valve positions must be avoided so that the nozzle itself will drain. (See Figure 6.)

Cleaning

Loose dirt particles in the cleaning solution can cause blockage that reduces the effectiveness of the live ring spinner. In order to avoid that condition from happening, it is imperative that an appropriate strainer be included in the cip system. The strainer should have holes no larger that 1.5mm (0.06").
