3.2 General Function Description The item numbers shown in brackets refer to Figure 7.5-1: Internal design; the letters in brackets refer to Figure 3.1-1: General Construction. The TANKO-RF is a mini-retractor system with a rotating spray head that is extended into the container for the cleaning procedure by means of the cleaning medium pressure only. The minimum opening pressure must be observed (see chapter 3.3 Technical Data ). The rotating spray head is driven by the cleaning medium. After switching off the cleaning medium supply, the spray head retracts into its housing by spring force and closes tightly with it. A quantity of cleaning medium trapped between the media supply and the closed plate as a result must be removed by suitable measures (installation angle, blowing out the device). The device is used for the interior cleaning of containers with and without installed equipment. The small TANKO-RF design was developed for use in small containers and for pipelines. The item numbers shown in brackets refer to Figure 7.5-1: Internal design RF40 and Figure 7.5-2: Internal design of RF50 The housing (1) forms a unit with the media connection (B) and process connection (A). The cleaning head (9) is extended and rotated by the media pressure. If the media pressure drops below the opening pressure of 1 bar, the cleaning head is pressed back into the housing by an internal spring and seals with the housing via an O-ring. The process connection [PC] is available in 2 variants (see Table 3.1-1: Dimensions and Weights ). The cleaning head (9) is mounted on 2 plain bearing bushes made of PEEK (7 and 8). The plate axle (2) at the lower end of the cleaning head is connected to the axle center section (3) via a wire locking pin (10). This is connected to the axle cover (3) via a thread. An O-ring (14) on the plate seals with the housing (1) when the cleaning head (9) is retracted. The spray angle of the cleaning head is approx. 80° in the direction of the housing. Due to the shape of the head and the closing function of the plate, the area below the plate is not sprayed with cleaning agent. The device is made of stainless steel and was developed, designed and built exclusively for industrial and commercial use. Several versions of the device are available for different applications and container dimensions.
