With the above configuration, when the element E to be cleaned is cleaned using the cleaning device C of this embodiment, the door 34 is opened, the element E to be cleaned is placed on the turntable 41, and the door 34 is closed. Then, the switch of the control box 30 is operated to start cleaning. When the switch is turned on, the turntable 41 rotates. On the other hand, the two high-pressure pumps 11a and 11b are selectively operated, and the high-pressure injection nozzle 13 moves up and down together with the high-pressure injection nozzle holding frame 17 by the vertical movement of the air cylinder 14 (arrow a). In the meantime, clean water (cleaning water) is jetted toward the inner wall surface or the outer wall surface of the element E to be cleaned, and cleaning is performed sequentially. The rotation operation of the turntable 41 can be adjusted as appropriate in relation to the operation of both the high-pressure injection nozzles 13. Further, the jet power and amount from both the high-pressure jet nozzles 13 can be adjusted as appropriate.
(洗浄方法)
次に、上記装置を用いた洗浄方法について説明する。ターンテーブル41上に載置されている被洗浄物は、円筒形で周面が網目状の被洗浄エレメントEであり、
(1)先ず、ターンテーブル41が一回転する間に、被洗浄エレメントE周面の内側の高圧噴射ノズル13は、高圧噴射ノズル保持枠17の上下動により、複数回移動しながら洗浄水が噴射する(この間、外側の高圧噴射ノズル13は噴射しない)。
(2)次いで、ターンテーブル41が更に一回転(2回転目)する間に、被洗浄エレメントEの外側の高圧噴射ノズル13から洗浄水が噴射する(この間、内側の高圧噴射ノズル13は噴射しない)。なお、(1)及び(2)において、高圧噴射ノズル13はターンテーブル41が一回転する間に複数回上下動を繰り返す。
(3)次いで、ターンテーブル41が、更に一回転(3回転目)する間に、洗浄エレメントEの上方に固定された2本の洗浄ノズル22により被洗浄エレメントEの内・外側周面にアルカリ洗浄水が噴射される。そして、上記工程後、すすぎ洗浄工程として再度(1)及び(2)の工程を繰り返させる。
(Cleaning method)
Next, a cleaning method using the above apparatus will be described. An object to be cleaned placed on the turntable 41 is an element to be cleaned E having a cylindrical shape and a mesh surface.
(1) First, while the turntable 41 makes one rotation, the high pressure spray nozzle 13 inside the circumferential surface of the element E to be cleaned is sprayed with the cleaning water while moving a plurality of times by the vertical movement of the high pressure spray nozzle holding frame 17. (In the meantime, the outer high-pressure jet nozzle 13 is not jetted).
(2) Next, while the turntable 41 makes one more rotation (second rotation), the cleaning water is sprayed from the high pressure spray nozzle 13 outside the element E to be cleaned (during this time, the inner high pressure spray nozzle 13 is not sprayed). ). In (1) and (2), the high pressure injection nozzle 13 repeats up and down movements a plurality of times while the turntable 41 makes one rotation.
(3) Next, while the turntable 41 makes one more rotation (third rotation), alkali is applied to the inner and outer peripheral surfaces of the element to be cleaned E by the two cleaning nozzles 22 fixed above the cleaning element E. Wash water is jetted. And after the said process, the process of (1) and (2) is repeated again as a rinse cleaning process.
また、前記洗浄方法における各工程は、被洗浄エレメントEを載置するターンテーブル41の回転毎に自動的に切り替わり、上記洗浄工程は、洗浄エレメントEの汚れの状況に応じて、工程全体として、或いは各工程のいずれかを適宜複数回繰り返して行うことができる。   Further, each step in the cleaning method is automatically switched every time the turntable 41 on which the element to be cleaned E is placed, and the cleaning step is performed as a whole according to the state of the dirt of the cleaning element E. Alternatively, any one of the steps can be appropriately repeated a plurality of times.
したがって、上記構成により、清水洗浄、アルカリ洗浄、及び、すすぎ洗浄を順次、洗浄エレメントEの回転と連動させて行わせる手段を採用したことで、被洗浄エレメント周面を効率的に万遍なく洗浄することができる。また、更に言えば、内周面に多数の補強枠を具備する円筒形のフィルタエレメントの洗浄では、載台の回転運動と洗浄ノズルの上下動により、構造上死角となりやすい曲線部分をも確実に洗浄することができて有用である。   Therefore, by adopting a means for performing clean water cleaning, alkali cleaning, and rinsing cleaning sequentially in conjunction with the rotation of the cleaning element E with the above configuration, the peripheral surface of the element to be cleaned is efficiently and uniformly cleaned. can do. In addition, when cleaning a cylindrical filter element having a large number of reinforcing frames on the inner peripheral surface, the curved portion that is likely to become a blind spot due to the rotational movement of the mounting table and the vertical movement of the cleaning nozzle is also ensured. It can be washed and is useful.
上記実施例では、生乳の加工に用いる場合の被洗浄エレメントの場合について説明したが、他の流体等の洗浄に用いる被洗浄エレメントの場合についても使用できることは言うまでもない。   In the above embodiment, the case of the element to be cleaned when used for processing raw milk has been described, but it goes without saying that it can also be used for the case of an element to be cleaned used for cleaning other fluids and the like.
