Description
本發明是有關於一種對洗淨對象的金屬板的表面噴射洗淨液的洗淨液噴射裝置及洗淨液噴射方法。The present invention relates to a cleaning liquid spraying device and a cleaning liquid spraying method for spraying a cleaning liquid onto a surface of a metal plate to be cleaned.
先前,在薄板等鋼板的生產線上,會在退火製程等規定的製程之前進行對壓延後的鋼板的表面進行洗淨的洗淨製程。通常,在壓延後的鋼板的表面上,附著有壓延油及鐵粉。在洗淨製程中,例如,一面利用噴灑(spray)裝置對鋼板表面噴射洗淨液,一面藉由刷輥(brush roll)的旋轉對鋼板表面進行刷洗,由此,自洗淨對象的鋼板的表面去除所附著的壓延油及鐵粉。Conventionally, in a production line of a steel sheet such as a thin plate, a washing process for washing the surface of the rolled steel sheet is performed before a predetermined process such as an annealing process. Usually, rolling oil and iron powder adhere to the surface of the rolled steel sheet. In the washing process, for example, a washing liquid is sprayed on the surface of the steel sheet by a spray device, and the surface of the steel sheet is brushed by the rotation of a brush roll, thereby washing the steel sheet of the object. The surface is removed by the attached rolling oil and iron powder.
又,在洗淨製程中,進行如下清洗處理:對如上所述實施洗淨液的噴射及刷洗之後的鋼板的表面,噴射規定壓力的水而洗滌鋼板的表面。其結果為,自洗淨對象的鋼板的表面沖走所殘留的鐵粉等。In the cleaning process, the surface of the steel sheet is washed by spraying water of a predetermined pressure on the surface of the steel sheet after the spraying and brushing of the cleaning liquid as described above. As a result, the iron powder remaining or the like is washed away from the surface of the steel sheet to be cleaned.
另一方面,所述洗淨製程中所使用的噴灑裝置通常包括:噴射噴嘴(噴灑噴嘴),對洗淨對象的鋼板的表面噴射洗淨液;以及噴灑配管(噴灑集管(spray header)),使洗淨液流通至噴射噴嘴。在此種噴灑裝置中,長時間地噴射洗淨液的結果會導致噴灑配管的內部被污染,由此會引起噴射噴嘴發生堵塞(阻塞)。為了防止所述現象,需要對噴灑配管的內部定期進行清掃。On the other hand, the spraying device used in the washing process generally includes: a spray nozzle (spray nozzle) that sprays a washing liquid onto the surface of the steel sheet to be cleaned; and a spray pipe (spray header) , the cleaning liquid is circulated to the spray nozzle. In such a spraying device, the result of spraying the washing liquid for a long time causes the inside of the spray pipe to be contaminated, thereby causing clogging (clogging) of the spray nozzle. In order to prevent this, it is necessary to periodically clean the inside of the spray pipe.
作為對噴灑配管的內部進行清掃的方法,先前是採用如下方法:停止包含噴灑裝置等洗淨設備的退火線等生產線的作業,在所述作業的停止期間拔出噴灑配管,在生產線外即在離線狀態下進行對已拔出的噴灑配管的內部的清掃。另一方面,具有如下的現有技術:在設置於噴灑配管的內部的旋轉軸上安裝刷主體(brush body),在所述旋轉軸的兩端之中突出至噴灑配管的外部的一端安裝手柄,藉由所述手柄的旋轉操作,而使刷主體與所述旋轉軸一併旋轉,在生產線內即於在線狀態下對噴灑配管的內部進行清掃(例如,參照專利文獻1)。 [現有技術文獻] [專利文獻]As a method of cleaning the inside of the spray pipe, a method of stopping the production line such as an annealing line including a washing device such as a spray device is performed, and the spray pipe is pulled out during the stop of the work, and is outside the production line. The cleaning of the inside of the extracted spray pipe is performed offline. On the other hand, there is a prior art in which a brush body is attached to a rotating shaft provided inside the spray pipe, and a handle is attached to one end of the rotating shaft that protrudes to the outside of the spray pipe. By the rotation operation of the handle, the brush main body is rotated together with the rotating shaft, and the inside of the spray pipe is cleaned in the line in the production line (for example, refer to Patent Document 1).

[發明所欲解決之課題][Problems to be solved by the invention]
在所述洗淨製程中,將用於鋼板表面的清洗處理的水,即,將鋼板表面的清洗處理時的廢液(以下稱為清洗廢液)加以回收,並將所回收的清洗廢液作為用以洗淨鋼板表面的洗淨液加以再利用,可有效節約水等資源及成本。In the cleaning process, water used for the cleaning treatment of the surface of the steel sheet, that is, waste liquid (hereinafter referred to as cleaning waste liquid) at the time of cleaning the surface of the steel sheet is recovered, and the recovered cleaning waste liquid is recovered. Recycling as a washing liquid for washing the surface of the steel sheet can effectively save resources and costs such as water.
然而,清洗廢液含有從鋼板表面沖走的鐵粉,因此當將清洗廢液作為鋼板表面的洗淨液加以再利用時,所述清洗廢液中的鐵粉(來自經清洗處理的鋼板表面的鐵粉)作為洗淨液中的夾雜物流入至噴灑配管內。在所述噴灑配管內的洗淨液中作為夾雜物而含有的鐵粉與自噴射噴嘴噴射至洗淨對象的鋼板表面的洗淨液一併流出,而過度附著至洗淨對象的鋼板表面。其結果為,會產生自洗淨對象的鋼板表面去除鐵粉等的洗淨製程變得不充分的問題。在所述現有技術中,難以抑制鐵粉等夾雜物與自噴射噴嘴噴射至洗淨對象的鋼板表面的洗淨液一併流出的事態,因此無法消除所述問題。However, the cleaning waste liquid contains iron powder washed away from the surface of the steel sheet, so when the cleaning waste liquid is reused as a washing liquid on the surface of the steel sheet, the iron powder in the cleaning waste liquid (from the surface of the cleaned steel sheet) The iron powder is introduced into the spray pipe as an inclusion in the washing liquid. The iron powder contained as an inclusion in the cleaning liquid in the spray pipe flows out together with the washing liquid sprayed from the spray nozzle onto the surface of the steel sheet to be cleaned, and excessively adheres to the surface of the steel sheet to be cleaned. As a result, there is a problem in that the cleaning process for removing iron powder or the like from the surface of the steel sheet to be cleaned is insufficient. In the above-described conventional technique, it is difficult to suppress the occurrence of inclusions such as iron powder and the cleaning liquid sprayed from the spray nozzle onto the surface of the steel sheet to be cleaned, and thus the problem cannot be eliminated.
進而,由於對鋼板表面的洗淨製程不充分,故而殘留在鋼板表面的鐵粉等夾雜物會導致在下一個製程中使鋼板表面的外觀變差。例如,當進行退火製程作為所述洗淨製程的下一個製程時,會將殘留在鋼板表面的鐵粉等夾雜物帶入至退火爐的內部,由此所述夾雜物附著在退火爐內的爐底輥(hearth roll)上。其結果會導致在退火爐內在鋼板表面上產生壓痕,因而鋼板表面的外觀變差。Further, since the cleaning process on the surface of the steel sheet is insufficient, inclusions such as iron powder remaining on the surface of the steel sheet may deteriorate the appearance of the surface of the steel sheet in the next process. For example, when the annealing process is performed as the next process of the cleaning process, inclusions such as iron powder remaining on the surface of the steel sheet are brought into the interior of the annealing furnace, whereby the inclusions adhere to the annealing furnace. On the hearth roll. As a result, an indentation is generated on the surface of the steel sheet in the annealing furnace, and thus the appearance of the surface of the steel sheet is deteriorated.

此處,在鋼板14的生產線上的洗淨製程中,在對洗淨對象的鋼板14的表面進行洗淨期間(以下稱為鋼板洗淨期間),對所述鋼板14的表面,自噴灑噴嘴3a~噴灑噴嘴3f的各個噴灑噴嘴噴射噴灑配管2內的洗淨液17。在本實施形態1中,洗淨液17在自洗淨液供給部12流入至噴灑配管2的內部的階段,含有磁性夾雜物。磁性夾雜物是例如鐵粉等具有磁性的夾雜物。Here, in the cleaning process on the production line of the steel sheet 14, the surface of the steel sheet 14 to be cleaned is cleaned (hereinafter referred to as the steel sheet cleaning period), and the surface of the steel sheet 14 is self-sprayed. Each of the spray nozzles 3a to 3f of the spray nozzle 3f sprays the cleaning liquid 17 in the spray pipe 2. In the first embodiment, the cleaning liquid 17 contains magnetic inclusions at the stage of flowing into the inside of the spray pipe 2 from the cleaning liquid supply unit 12. The magnetic inclusions are magnetic inclusions such as iron powder.
磁化部9在洗淨製程的鋼板洗淨期間,如以上所述使旋轉軸5磁化。洗淨液噴射裝置1使存在於噴灑配管2的內部的洗淨液17中的磁性夾雜物吸附至藉由磁化部9而磁化的旋轉軸5,由此,將洗淨液17與磁性夾雜物加以分離而自噴灑配管2內的洗淨液17去除磁性夾雜物。噴灑配管2使磁性夾雜物去除後的洗淨液17一面沿自入口側向出口側的流通方向流通,一面流通至噴灑噴嘴3a~噴灑噴嘴3f的各個噴灑噴嘴。洗淨液噴射裝置1將噴灑配管2內的磁性夾雜物去除後的洗淨液17,自噴灑噴嘴3a~噴灑噴嘴3f噴射至洗淨對象的鋼板14的表面。The magnetized portion 9 magnetizes the rotary shaft 5 as described above during the cleaning of the steel sheet in the cleaning process. In the cleaning liquid ejecting apparatus 1, the magnetic inclusions in the cleaning liquid 17 existing inside the spray pipe 2 are adsorbed to the rotating shaft 5 magnetized by the magnetization portion 9, whereby the cleaning liquid 17 and the magnetic inclusions are removed. The magnetic inclusions are removed from the cleaning liquid 17 in the spray pipe 2 by separation. In the spray pipe 2, the cleaning liquid 17 after the magnetic inclusions are removed flows in the flow direction from the inlet side to the outlet side, and flows to the respective spray nozzles of the spray nozzles 3a to 3f. In the cleaning liquid ejecting apparatus 1, the cleaning liquid 17 from which the magnetic inclusions in the spray pipe 2 are removed is sprayed from the spray nozzles 3a to 3f to the surface of the steel sheet 14 to be cleaned.

The cleaning waste liquid 15 is a waste liquid recovered from the steel sheet 14 during the self-cleaning treatment as described above, and contains magnetic inclusions such as iron powder washed away from the surface of the steel sheet 14 by the cleaning treatment. On the other hand, the cleaning liquid supply unit 12 appropriately receives the new cleaning liquid 16 from a predetermined supply source (not shown) through the pipe 13b. The new cleaning liquid 16 is a new cleaning liquid instead of a reusing cleaning liquid, and contains almost no inclusions, both magnetically and non-magnetically.

Hereinafter, a method of ejecting the cleaning liquid according to the first embodiment of the present invention will be described in detail with reference to Figs. 3 to 7 .
本發明的實施形態1的洗淨液噴射方法是在鋼板14的洗淨製程中,利用洗淨液噴射裝置1,去除洗淨液17中所含的磁性夾雜物,將所述磁性夾雜物去除後的洗淨液17噴射至依次被搬運的鋼板14的表面的方法。In the cleaning liquid spraying method of the first embodiment of the present invention, the magnetic inclusions contained in the cleaning liquid 17 are removed by the cleaning liquid ejecting apparatus 1 in the cleaning process of the steel sheet 14, and the magnetic inclusions are removed. The subsequent cleaning liquid 17 is ejected to the surface of the steel sheet 14 that is sequentially conveyed.
具體而言,在本發明的實施形態1的洗淨液噴射方法中,洗淨液噴射裝置1如圖3所示,對清洗廢液15進行再利用而形成為洗淨液17,將所述洗淨液17依次供給至噴灑配管2(洗淨液供給步驟)。此時,廢液回收部11將已回收完的清洗廢液15通過配管13a依次送出至洗淨液供給部12。洗淨液供給部12使自廢液回收部11送出的清洗廢液15與通過配管13b而流入的新洗淨液16混合,由此,生成對清洗廢液15進行再利用而成的洗淨液17。即,在本實施形態1中,洗淨液17至少含有清洗廢液15。洗淨液供給部12將此種洗淨液17通過配管13c依次供給至噴灑配管2內。Specifically, in the cleaning liquid ejecting method according to the first embodiment of the present invention, the cleaning liquid ejecting apparatus 1 re-uses the cleaning waste liquid 15 to form the cleaning liquid 17 as shown in FIG. The cleaning liquid 17 is sequentially supplied to the spray pipe 2 (cleaning liquid supply step). At this time, the waste liquid recovery unit 11 sequentially delivers the collected cleaning waste liquid 15 to the cleaning liquid supply unit 12 through the pipe 13a. The cleaning liquid supply unit 12 mixes the cleaning waste liquid 15 sent from the waste liquid recovery unit 11 with the new cleaning liquid 16 that has flowed in through the pipe 13b, thereby generating a cleaning for recycling the cleaning waste liquid 15. Liquid 17. That is, in the first embodiment, the cleaning liquid 17 contains at least the cleaning waste liquid 15. The cleaning liquid supply unit 12 sequentially supplies the cleaning liquid 17 into the spray pipe 2 through the pipe 13c.
接著,洗淨液噴射裝置1使旋轉刷4的旋轉軸5磁化,使存在於噴灑配管2內的洗淨液17中的磁性夾雜物吸附至磁化狀態的旋轉軸5,並自噴灑配管2內的洗淨液17去除磁性夾雜物(磁化步驟)。在洗淨液噴射裝置1中,噴灑配管2是使洗淨液17流通至噴灑噴嘴3a~噴灑噴嘴3f的流通管。旋轉軸5是以所述噴灑配管2的管軸方向為中心進行旋轉而對噴灑配管2的內部進行清掃的旋轉刷4的旋轉中心的軸體,如以上所述,利用軟磁性體而形成。再者,旋轉刷4在鋼板洗淨期間,不旋轉而處於靜止。Then, the cleaning liquid ejecting apparatus 1 magnetizes the rotating shaft 5 of the rotating brush 4, and the magnetic inclusions in the cleaning liquid 17 existing in the spray pipe 2 are adsorbed to the rotating shaft 5 in the magnetized state, and are sprayed from the spray pipe 2 The cleaning solution 17 removes magnetic inclusions (magnetization step). In the cleaning liquid spraying device 1, the spray pipe 2 is a flow pipe through which the cleaning liquid 17 is caused to flow to the spray nozzles 3a to 3f. The rotary shaft 5 is a shaft body that rotates around the tube axis direction of the spray pipe 2 and cleans the inside of the spray pipe 2, and is formed of a soft magnetic body as described above. Further, the rotating brush 4 is stationary while not being rotated during the cleaning of the steel sheet.
在所述磁化步驟中,磁化部9對規定的切換開關(未圖示)進行操作等,而在鋼板洗淨期間,使永久磁鐵等硬磁性體與旋轉軸5接觸。由此,磁化部9使旋轉軸5磁化而形成為磁化狀態,在鋼板洗淨期間,維持著所述旋轉軸5的磁化狀態。此處,噴灑配管2使自洗淨液供給部12收入的洗淨液17如以上所述沿規定的流通方向流通。此時,噴灑配管2的排出閥2d為關閉狀態,阻擋洗淨液17自排出口2c流通(排出)。磁化狀態的旋轉軸5如圖4所示,藉由磁力而吸附沿規定的流通方向(自噴灑配管2的入口側向出口側的流通方向)在噴灑配管2內流通的洗淨液17中的磁性夾雜物19。由此,磁化狀態的旋轉軸5將在噴灑配管2內流通的洗淨液17與存在於噴灑配管2內的磁性夾雜物19加以分離,自所述洗淨液17充分去除磁性夾雜物19。In the magnetization step, the magnetizing unit 9 operates a predetermined switch (not shown) or the like, and a hard magnetic material such as a permanent magnet is brought into contact with the rotating shaft 5 during the cleaning of the steel sheet. Thereby, the magnetized portion 9 magnetizes the rotating shaft 5 to be in a magnetized state, and maintains the magnetization state of the rotating shaft 5 during the cleaning of the steel sheet. Here, the spray pipe 2 allows the cleaning liquid 17 received from the cleaning liquid supply unit 12 to flow in a predetermined flow direction as described above. At this time, the discharge valve 2d of the spray pipe 2 is in a closed state, and the blocked cleaning liquid 17 is circulated (discharged) from the discharge port 2c. As shown in FIG. 4, the rotating shaft 5 in the magnetized state is adsorbed by the magnetic force in the cleaning liquid 17 flowing through the spray pipe 2 in a predetermined flow direction (flow direction from the inlet side to the outlet side of the spray pipe 2). Magnetic inclusions 19. In this way, the rotating shaft 5 in the magnetized state separates the cleaning liquid 17 flowing through the spray pipe 2 from the magnetic inclusions 19 existing in the spray pipe 2, and the magnetic inclusions 19 are sufficiently removed from the cleaning liquid 17.
再者,作為噴灑配管2內的磁性夾雜物19,例如可舉出:流入至噴灑配管2內的洗淨液17中原本含有的磁性夾雜物、以及自旋轉刷4的各刷子6a~刷子6g、刷子7a~刷子7f或噴灑配管2的內壁面2e等脫落的磁性夾雜物。In addition, as the magnetic inclusions 19 in the spray pipe 2, for example, magnetic inclusions originally contained in the cleaning liquid 17 flowing into the spray pipe 2, and brushes 6a to 6g of the spinner brush 4 are exemplified.

所述磁化步驟之後,洗淨液噴射裝置1將在噴灑配管2內流通的磁性夾雜物去除後的洗淨液17自噴灑噴嘴3a~噴灑噴嘴3f噴射至洗淨對象的鋼板14的表面(噴射步驟)。在所述噴射步驟中,如圖3所示,噴灑配管2一面使磁性夾雜物去除後的洗淨液17沿所述流通方向流通,一面使所述磁性夾雜物去除後的洗淨液17流通至噴灑噴嘴3a~噴灑噴嘴3f的各個噴灑噴嘴。噴灑噴嘴3a~噴灑噴嘴3f的各個噴灑噴嘴將自噴灑配管2內流通的磁性夾雜物去除後的洗淨液17噴射至鋼板14的表面。此時,噴灑噴嘴3a~噴灑噴嘴3f如圖3所示,在框體10內,遍及依次被搬運的鋼板14的寬度方向上(參照圖1)的整個區域,噴射磁性夾雜物去除後的洗淨液17。After the magnetization step, the cleaning liquid ejecting apparatus 1 ejects the cleaning liquid 17 from which the magnetic inclusions flowing in the spray pipe 2 are removed from the spray nozzles 3a to 3f to the surface of the steel sheet 14 to be cleaned (jetting step). In the spraying step, as shown in FIG. 3, the cleaning pipe 17 in which the magnetic inclusions are removed is distributed in the flow direction, and the cleaning liquid 17 after the magnetic inclusions are removed is circulated. To each of the spray nozzles of the spray nozzles 3a to 3f. Each of the spray nozzles of the spray nozzles 3a to 3f sprays the cleaning liquid 17 from which the magnetic inclusions flowing in the spray pipe 2 are removed, onto the surface of the steel sheet 14. At this time, as shown in FIG. 3, the spray nozzles 3a to 3f are washed in the entire casing 10 in the width direction of the steel sheet 14 (see FIG. 1) which is sequentially conveyed, and after the magnetic inclusions are removed. Clean liquid 17.

Thereby, deposits such as rolling oil or iron powder are removed from the surface of the steel sheet 14. Thereafter, the surface of the steel sheet 14 is cleaned, and the cleaning process of the steel sheet 14 is completed. The cleaning waste liquid 15 at the time of the cleaning treatment is recovered by the waste liquid recovery unit 11 and reused for washing of the steel sheet 14 after the next time. In the cleaning liquid spraying method according to the first embodiment of the present invention, the cleaning liquid supply step, the magnetization step, and the spraying step are sequentially performed in sequence or in parallel in the cleaning process of the steel sheet 14 that is continuously conveyed.
另一方面,在本發明的實施形態1的洗淨液噴射方法中,在規定的期間內繼續進行包含所述洗淨液供給步驟、磁化步驟及噴射步驟的鋼板14的洗淨製程之後,於在線狀態下對洗淨液噴射裝置1的噴灑配管2的內部定期地進行清掃。On the other hand, in the cleaning liquid ejecting method according to the first embodiment of the present invention, after the cleaning process of the steel sheet 14 including the cleaning liquid supply step, the magnetization step, and the ejecting step is continued for a predetermined period of time, The inside of the spray pipe 2 of the cleaning liquid spray device 1 is periodically cleaned in an online state.
具體而言,在利用本發明的實施形態1的洗淨液噴射方法的噴灑配管2內的清掃中,洗淨液噴射裝置1如圖5所示,對清洗廢液15進行再利用而形成為洗淨液17,將所述洗淨液17依次供給至噴灑配管2(管內清掃時的洗淨液供給步驟)。此時,如圖5所示,廢液回收部11與所述鋼板表面洗淨時的情況同樣地,將已回收完的清洗廢液15通過配管13a依次送出至洗淨液供給部12。洗淨液供給部12使來自廢液回收部11的清洗廢液15與來自配管13b的新洗淨液16混合。由此,洗淨液供給部12對清洗廢液15進行再利用,生成用於清掃噴灑配管2內的洗淨液17。洗淨液供給部12通過配管13c將此種洗淨液17依次供給至噴灑配管2內。Specifically, in the cleaning in the spray pipe 2 by the cleaning liquid spraying method according to the first embodiment of the present invention, the cleaning liquid ejecting apparatus 1 re-uses the cleaning waste liquid 15 as shown in FIG. The cleaning liquid 17 sequentially supplies the cleaning liquid 17 to the spray pipe 2 (the washing liquid supply step in the pipe cleaning). At this time, as shown in FIG. 5, the waste liquid recovery part 11 sequentially delivers the collected cleaning waste liquid 15 to the cleaning liquid supply unit 12 through the pipe 13a in the same manner as in the case of washing the surface of the steel sheet. The cleaning liquid supply unit 12 mixes the cleaning waste liquid 15 from the waste liquid recovery unit 11 with the new cleaning liquid 16 from the piping 13b. Thereby, the cleaning liquid supply unit 12 reuses the cleaning waste liquid 15 to generate the cleaning liquid 17 for cleaning the inside of the spray pipe 2. The cleaning liquid supply unit 12 sequentially supplies the cleaning liquid 17 into the spray pipe 2 through the pipe 13c.
接著,洗淨液噴射裝置1消除旋轉刷4的旋轉軸5的磁化狀態,而使旋轉軸5為非磁化狀態(消磁步驟)。在所述消磁步驟中,磁化部9對規定的切換開關(未圖示)進行操作等,而使與用於磁化的旋轉軸5接觸的硬磁性體和旋轉軸5隔離。由此,磁化部9將藉由所述磁化步驟而磁化的旋轉軸5,在噴灑配管2的管內清掃期間內,自磁化狀態切換為非磁化狀態,在管內清掃期間內,維持著所述旋轉軸5的非磁化狀態。磁化部9如上所述使旋轉軸5為非磁化狀態,而使磁性夾雜物自旋轉軸5脫離。其結果為,非磁化狀態的旋轉軸5如圖6所示,將藉由磁化狀態時的磁力而吸附著的磁性夾雜物19釋放至噴灑配管2內的洗淨液17中。Next, the cleaning liquid ejecting apparatus 1 eliminates the magnetization state of the rotating shaft 5 of the rotating brush 4, and causes the rotating shaft 5 to be in a non-magnetized state (demagnetization step). In the degaussing step, the magnetizing portion 9 operates a predetermined switching switch (not shown) or the like to isolate the hard magnetic material that is in contact with the rotating shaft 5 for magnetization from the rotating shaft 5. As a result, the magnetized portion 9 switches the rotating shaft 5 magnetized by the magnetization step from the magnetized state to the non-magnetized state during the in-tube cleaning of the spray pipe 2, and maintains the inside of the in-tube cleaning period. The non-magnetized state of the rotating shaft 5 is described. As described above, the magnetized portion 9 causes the rotating shaft 5 to be in a non-magnetized state, and the magnetic inclusions are detached from the rotating shaft 5. As a result, as shown in FIG. 6, the rotating shaft 5 in the non-magnetized state releases the magnetic inclusions 19 adsorbed by the magnetic force in the magnetized state into the cleaning liquid 17 in the spray pipe 2.
接著,洗淨液噴射裝置1利用旋轉刷4對噴灑配管2的內部進行清掃(管內清掃步驟)。在所述管內清掃步驟中,清掃對象的噴灑配管2處於被安裝在洗淨液噴射裝置1內(例如框體10等)的狀態,即,處於在線的狀態。旋轉刷4藉由操作者對手柄8的旋轉操作,以軸支於所述噴灑配管2上的狀態的旋轉軸5為中心進行旋轉。Next, the cleaning liquid spraying device 1 cleans the inside of the spray pipe 2 by the rotating brush 4 (in-pipe cleaning step). In the in-pipe cleaning step, the cleaning pipe 2 to be cleaned is in a state of being mounted in the cleaning liquid ejecting apparatus 1 (for example, the casing 10 or the like), that is, in an online state. The rotary brush 4 is rotated about the rotation shaft 5 that is axially supported on the spray pipe 2 by the rotation operation of the handle 8 by the operator.
此時,旋轉刷4的旋轉軸5如圖5所示,以噴灑配管2的管軸方向為中心進行旋轉。伴隨著所述旋轉軸5的旋轉,旋轉刷4的刷子6a~刷子6g、刷子7a~刷子7f一面沿旋轉軸5的外周方向進行旋轉,一面對噴灑配管2的內部進行刷洗。例如,如圖7所示,刷子6c、刷子7c一面沿旋轉軸5的外周方向進行旋轉,一面對噴灑配管2的內壁面2e及噴灑噴嘴3c的內側進行刷洗。刷子6a~刷子6g、刷子7a~刷子7f如圖7所例示,對噴灑配管2的內壁面2e及噴灑噴嘴3a~噴灑噴嘴3f的各內側分別進行刷洗,由此,自內壁面2e及噴灑噴嘴3a~噴灑噴嘴3f的各內側將污垢作為夾雜物而擦落。旋轉刷4藉由手柄8的旋轉操作,而將以管軸方向為中心的旋轉的方向如圖5、圖7所示適當切換為反方向,由此於在線狀態下對噴灑配管2的內部有效率地進行刷洗而加以清掃。At this time, as shown in FIG. 5, the rotating shaft 5 of the rotating brush 4 rotates around the tube axis direction of the spray pipe 2. With the rotation of the rotary shaft 5, the brushes 6a to 6g and the brushes 7a to 7f of the rotary brush 4 rotate in the outer circumferential direction of the rotary shaft 5, and are brushed toward the inside of the spray pipe 2. For example, as shown in Fig. 7, the brush 6c and the brush 7c are rotated in the outer circumferential direction of the rotary shaft 5, and are brushed toward the inner wall surface 2e of the spray pipe 2 and the inner side of the spray nozzle 3c. As shown in Fig. 7, the brush 6a to the brush 6g and the brush 7a to the brush 7f respectively brush the inner wall surface 2e of the spray pipe 2 and the spray nozzles 3a to 3f, respectively, from the inner wall surface 2e and the spray nozzle. Each of the inner sides of the spray nozzles 3f to 3a wipes the dirt as an inclusion. The rotating brush 4 is rotated in the direction of the tube axis by the rotation operation of the handle 8, and the direction of rotation about the tube axis direction is appropriately switched to the reverse direction as shown in FIGS. 5 and 7, so that the inside of the spray pipe 2 is provided in the online state. Brush it efficiently and clean it.
藉由如上所述的刷洗而自內壁面2e及噴灑噴嘴3a~噴灑噴嘴3f的各內側去除的污垢(夾雜物)與如上所述自非磁化狀態的旋轉軸5脫離的磁性夾雜物一併,懸浮在噴灑配管2內的洗淨液17中。以下,將該些作為污垢而去除的夾雜物及自非磁化狀態的旋轉軸5脫離的磁性夾雜物19加以總稱而適當簡稱為「磁性夾雜物19等各種夾雜物」。The dirt (inclusions) removed from the inner wall surface 2e and the respective inner sides of the spray nozzles 3a to 3f by the brushing as described above are combined with the magnetic inclusions separated from the non-magnetized rotating shaft 5 as described above. It is suspended in the washing liquid 17 in the spray pipe 2. In the meantime, the inclusions removed as dirt and the magnetic inclusions 19 which are detached from the non-magnetized rotating shaft 5 are collectively referred to as "variable inclusions such as magnetic inclusions 19".
又,在所述管內清掃步驟中,洗淨液17如圖5所示,自配管13c繼續流入至噴灑配管2內,且沿自噴灑配管2的入口側向出口側的流通方向進行流通。另一方面,排出閥2d在需要的時刻自關閉狀態切換為打開狀態,由此,容許廢液自排出口2c排出。此時,噴灑配管2內的洗淨液17一面猛力地向所述流通方向流通,一面將來自旋轉軸5的磁性夾雜物19及殘留在噴灑配管2內的夾雜物(例如附著在圖6所示的刷子6b、刷子6c、刷子7a、刷子7b上的夾雜物等)向排出口2c搬運。In the in-pipe cleaning step, the cleaning liquid 17 continues to flow into the spray pipe 2 from the pipe 13c as shown in Fig. 5, and flows in the flow direction from the inlet side to the outlet side of the spray pipe 2. On the other hand, the discharge valve 2d is switched from the closed state to the open state at a required timing, whereby the waste liquid is allowed to be discharged from the discharge port 2c. At this time, the cleaning liquid 17 in the spray pipe 2 is violently circulated in the flow direction, and the magnetic inclusions 19 from the rotating shaft 5 and the inclusions remaining in the spray pipe 2 are attached (for example, attached to FIG. 6). The illustrated brush 6b, brush 6c, brush 7a, inclusions on the brush 7b, and the like are conveyed to the discharge port 2c.
洗淨液噴射裝置1將藉由所述消磁步驟而自旋轉軸5脫離的磁性夾雜物19,與利用旋轉刷4清掃噴灑配管2的內部時所使用的洗淨液17一併通過噴灑配管2的排出口2c排出至外部。與此同時,洗淨液噴射裝置1將如上所述藉由刷洗而去除的夾雜物(噴灑配管2內的污垢),與所述洗淨液17一併通過噴灑配管2的排出口2c排出至外部。用於如上所述的噴灑配管2內的清掃之後的洗淨液17,即,管內清掃後的洗淨液17如圖5所示,作為含有噴灑配管2內的磁性夾雜物19等各種夾雜物的清掃廢液18而自排出口2c排出至外部(線外)。In the cleaning liquid ejecting apparatus 1 , the magnetic inclusions 19 detached from the rotating shaft 5 by the degaussing step are passed through the spray pipe 2 together with the cleaning liquid 17 used when the inside of the spray pipe 2 is cleaned by the rotating brush 4 . The discharge port 2c is discharged to the outside. At the same time, the cleaning liquid ejecting apparatus 1 discharges the inclusions (soil in the spray pipe 2) removed by the brushing as described above, together with the cleaning liquid 17 through the discharge port 2c of the spray pipe 2 to external. The cleaning liquid 17 after the cleaning in the spray pipe 2 as described above, that is, the cleaning liquid 17 after the inside of the pipe cleaning, as shown in FIG. 5, contains various inclusions such as the magnetic inclusions 19 in the spray pipe 2. The waste liquid 18 is cleaned and discharged to the outside (outside line) from the discharge port 2c.
在如上所述的管內清掃步驟中,依次或並列地繼續進行洗淨液17在所述噴灑配管2內的流通、藉由旋轉刷4的旋轉而進行的噴灑配管2內的刷洗、以及含有噴灑配管2內的磁性夾雜物19等各種夾雜物的管內清掃後的洗淨液17(清掃廢液18)的排出,直至在線狀態下的噴灑配管2內的清掃結束。在本發明的實施形態1的洗淨液噴射方法中,所述在線狀態下的噴灑配管2內的清掃結束之後,再開始進行包含所述洗淨液供給步驟、磁化步驟及噴射步驟的鋼板14的洗淨製程。In the in-pipe cleaning step as described above, the flow of the cleaning liquid 17 in the spray pipe 2, the brushing in the spray pipe 2 by the rotation of the rotary brush 4, and the like are continued in sequence or in parallel. The discharge of the cleaning liquid 17 (cleaning waste liquid 18) after the cleaning of the various inclusions such as the magnetic inclusions 19 in the piping 2 is completed until the cleaning in the spray pipe 2 in the line state is completed. In the cleaning liquid spraying method according to the first embodiment of the present invention, after the cleaning in the spray pipe 2 in the online state is completed, the steel sheet 14 including the cleaning liquid supply step, the magnetization step, and the spraying step is restarted. Washing process.
再者,在所述管內清掃步驟中,噴灑噴嘴3a~噴灑噴嘴3f的各個噴灑噴嘴藉由操作切換開關(未圖示)等而關閉噴射口,停止對鋼板14的表面噴射洗淨液17。在如上所述的狀態下,對鋼板14的表面噴射洗淨液17可藉由其他洗淨液噴射裝置來代行。例如,亦可沿鋼板14的搬運方向設置多個本發明的實施形態1的洗淨液噴射裝置1,藉由該些多個洗淨液噴射裝置1之中除了正在清掃的洗淨液噴射裝置1以外的剩下的洗淨液噴射裝置1,來代行所述洗淨液17的噴射。Further, in the in-pipe cleaning step, each of the spray nozzles of the spray nozzles 3a to 3f is closed by the operation of a changeover switch (not shown) or the like, and the washing of the surface of the steel sheet 14 is stopped. . In the state as described above, the cleaning liquid 17 is sprayed on the surface of the steel sheet 14 by another cleaning liquid ejecting apparatus. For example, a plurality of the cleaning liquid ejecting apparatuses 1 of the first embodiment of the present invention may be provided along the conveying direction of the steel sheet 14, and the cleaning liquid ejecting apparatus of the plurality of cleaning liquid ejecting apparatuses 1 may be cleaned. The remaining cleaning liquid ejecting apparatus 1 other than 1 is substituted for the ejection of the cleaning liquid 17.
又,在所述管內清掃步驟中,在使虛設線圈(dummy coil)通入等不使製品的鋼板14通入的情況下,亦可保持著打開噴灑噴嘴3a~噴灑噴嘴3f的噴射口而不關閉的狀態來進行噴灑配管2的管內清掃。Further, in the in-pipe cleaning step, when the dummy coil is inserted or the like, the steel plate 14 of the product is not introduced, the injection port of the spray nozzle 3a to the spray nozzle 3f can be held. The in-tube cleaning of the spray pipe 2 is performed in a state of not being closed.
如以上所述,在本發明的實施形態1中,使旋轉刷的旋轉軸磁化,而使存在於噴灑配管的內部的洗淨液中的磁性夾雜物吸附至所述磁化狀態的旋轉軸,自所述洗淨液去除磁性夾雜物,而將磁性夾雜物去除後的洗淨液自噴灑噴嘴噴射至洗淨對象的鋼板等金屬板表面,所述旋轉刷是以使洗淨液流通至噴灑噴嘴的噴灑配管的管軸方向為中心進行旋轉而對噴灑配管的內部進行清掃。As described above, in the first embodiment of the present invention, the rotating shaft of the rotating brush is magnetized, and the magnetic inclusions in the cleaning liquid existing inside the spray pipe are adsorbed to the rotating shaft in the magnetized state. The cleaning liquid removes the magnetic inclusions, and the cleaning liquid after removing the magnetic inclusions is sprayed from the spray nozzle to the surface of the metal plate such as a steel plate to be cleaned, and the rotary brush is used to circulate the cleaning liquid to the spray nozzle. The direction of the tube axis of the spray pipe is rotated to clean the inside of the spray pipe.
因此,可將在自噴灑噴嘴進行噴射之前存在於噴灑配管內的洗淨液與所述洗淨液中的磁性夾雜物加以分離,使經分離的磁性夾雜物保留在配置於噴灑配管內的旋轉刷的旋轉軸上,並且將與磁性夾雜物分離之後的洗淨液自噴灑噴嘴噴射至金屬板表面。由此,即使是在金屬板表面的清洗處理時將所回收的清洗廢液再利用為洗淨液的情況下,亦可儘可能地降低伴隨著自噴灑噴嘴噴射洗淨液而產生的磁性夾雜物的流出量。其結果為,當自噴灑噴嘴噴射洗淨液而對金屬板表面進行洗淨時,可減少噴灑噴嘴的噴射口上的磁性夾雜物的附著量,防止噴灑噴嘴的堵塞,並且抑制將鐵粉等磁性夾雜物與洗淨液一併噴射至洗淨對象的金屬板表面的事態。Therefore, the cleaning liquid existing in the spray pipe before being ejected from the spray nozzle can be separated from the magnetic inclusions in the cleaning liquid, and the separated magnetic inclusions can be retained in the rotation disposed in the spray pipe. The rotating shaft of the brush is sprayed, and the washing liquid separated from the magnetic inclusions is sprayed from the spraying nozzle to the surface of the metal plate. Therefore, even when the recovered cleaning waste liquid is reused as the cleaning liquid during the cleaning treatment of the surface of the metal plate, the magnetic inclusions accompanying the ejection of the cleaning liquid from the spray nozzle can be reduced as much as possible. The outflow of the object. As a result, when the surface of the metal plate is washed by spraying the cleaning liquid from the spray nozzle, the amount of adhesion of the magnetic inclusions on the injection port of the spray nozzle can be reduced, the clogging of the spray nozzle can be prevented, and the magnetic properties such as iron powder can be suppressed. The matter in which the inclusions are sprayed together with the cleaning liquid onto the surface of the metal plate to be cleaned.
藉由將本發明應用於金屬板表面的洗淨製程,可一面將清洗廢液再利用為洗淨液,一面對洗淨對象的金屬板表面進行充分洗淨。其結果為,可節約水等資源及成本,並且自金屬板表面充分去除在金屬板表面的洗淨製程的下一個製程(例如退火製程)中導致金屬板表面的外觀變差的鐵粉等金屬粒狀物,因此可儘可能地抑制由金屬粒狀物引起的金屬板表面的壓痕等外觀不良。By applying the present invention to the cleaning process of the surface of the metal plate, the cleaning waste liquid can be reused as the cleaning liquid, and the surface of the metal plate to be cleaned can be sufficiently washed. As a result, it is possible to save resources such as water and the like, and to sufficiently remove metal such as iron powder which deteriorates the appearance of the surface of the metal plate in the next process (for example, an annealing process) of the cleaning process on the surface of the metal plate from the surface of the metal plate. Since the granules are formed, it is possible to suppress appearance defects such as indentation on the surface of the metal plate caused by the metal granules as much as possible.
又,在本發明的實施形態1中,在對金屬板表面進行洗淨期間,使噴灑配管內的旋轉刷的旋轉軸磁化,使噴灑配管內的磁性夾雜物吸附至所述磁化狀態的旋轉軸,而自噴灑配管內的洗淨液去除磁性夾雜物,在對噴灑配管內進行清掃期間(管內清掃期間),如上所述將經磁化的旋轉軸自磁化狀態切換為非磁化狀態,使吸附著的磁性夾雜物自所述非磁化狀態的旋轉軸脫離。進而,在所述管內清掃期間,利用旋轉刷對噴灑配管內進行清掃,並且將如上所述已脫離的磁性夾雜物,與利用旋轉刷清掃噴灑配管內時所使用的洗淨液一併通過噴灑配管的排出口排出至外部。Further, in the first embodiment of the present invention, during the cleaning of the surface of the metal plate, the rotating shaft of the rotating brush in the spray pipe is magnetized, and the magnetic inclusions in the spray pipe are adsorbed to the rotating shaft of the magnetized state. The magnetic inclusions are removed from the cleaning liquid in the spray pipe, and during the cleaning of the spray pipe (during the pipe cleaning), the magnetized rotating shaft is switched from the magnetized state to the non-magnetized state as described above, so that the adsorption is performed. The magnetic inclusions are detached from the rotating shaft of the non-magnetized state. Further, during the in-tube cleaning, the inside of the spray pipe is cleaned by a rotating brush, and the magnetic inclusions which have been detached as described above are passed together with the cleaning liquid used for cleaning the spray pipe by the rotary brush. The discharge port of the spray pipe is discharged to the outside.
因此,無須在洗淨製程的線外拆下噴灑配管,而可於在線狀態下對噴灑配管內進行清掃,並且可適時地切換使噴灑配管內的磁性夾雜物吸附至旋轉刷的旋轉軸的狀態、以及使吸附至所述旋轉軸上的磁性夾雜物脫離至噴灑配管內的洗淨液中的狀態,自噴灑配管內向線外定期地排出磁性夾雜物。由此,可防止磁性夾雜物過度地殘留在噴灑配管內的事態,其結果可抑制自噴灑噴嘴流出磁性夾雜物,並且有效率地防止噴灑噴嘴的堵塞。Therefore, it is not necessary to remove the spray pipe outside the line of the cleaning process, and the inside of the spray pipe can be cleaned in an on-line state, and the state in which the magnetic inclusions in the spray pipe are adsorbed to the rotating shaft of the rotary brush can be switched in a timely manner. And the magnetic inclusions adsorbed on the rotating shaft are detached from the washing liquid in the spray pipe, and the magnetic inclusions are periodically discharged from the inside of the spray pipe to the outside of the spray pipe. Thereby, it is possible to prevent the magnetic inclusions from remaining excessively in the spray pipe, and as a result, it is possible to suppress the magnetic inclusions from flowing out from the spray nozzle and to effectively prevent clogging of the spray nozzle.

硬磁性體29a是利用永久磁鐵等而構成,可沿旋轉軸25的內周面旋轉滑動地組裝於旋轉刷4的旋轉軸25的內部。此時,硬磁性體29a使其N極的端部及S極的端部與旋轉軸25的磁性軸部25a或非磁性軸部25b中的任一者接觸。The hard magnetic material 29a is configured by a permanent magnet or the like, and is rotatably slidably fitted to the inner peripheral surface of the rotating shaft 25 to be incorporated inside the rotating shaft 25 of the rotating brush 4. At this time, the hard magnetic material 29a has its N-terminal end portion and the S-pole end portion in contact with either of the magnetic shaft portion 25a or the non-magnetic shaft portion 25b of the rotating shaft 25.
切換部29b是用以將旋轉刷4的旋轉軸25切換為磁化狀態及非磁化狀態的構件。具體而言,如圖8所示,切換部29b可旋轉地設置在手柄8的抓捏側(握持部側)的外壁部。在切換部29b上,固定有驅動軸29c的一端。所述驅動軸29c的另一端固定在旋轉軸25內的硬磁性體29a上。切換部29b根據操作者的旋轉操作,與手柄8獨立地進行旋轉,且伴隨於此,使硬磁性體29a與驅動軸29c一併以旋轉軸25的長度方向軸為中心進行旋轉。切換部29b藉由所述硬磁性體29a的旋轉,而將旋轉軸25切換為磁化狀態及非磁化狀態。The switching unit 29b is a member for switching the rotating shaft 25 of the rotating brush 4 into a magnetized state and a non-magnetized state. Specifically, as shown in FIG. 8 , the switching portion 29 b is rotatably provided on the outer wall portion of the gripping side (the grip portion side) of the handle 8 . One end of the drive shaft 29c is fixed to the switching portion 29b. The other end of the drive shaft 29c is fixed to the hard magnetic body 29a in the rotary shaft 25. The switching unit 29b rotates independently of the handle 8 in accordance with the rotation operation of the operator, and accordingly, the hard magnetic material 29a and the drive shaft 29c are rotated about the longitudinal axis of the rotary shaft 25. The switching unit 29b switches the rotating shaft 25 to a magnetized state and a non-magnetized state by the rotation of the hard magnetic material 29a.
具有所述構成的磁化部29對應於切換部29b的旋轉,使旋轉軸25內的硬磁性體29a沿旋轉軸25的內周面旋轉,由此,使旋轉軸25為磁化狀態或非磁化狀態。圖11是說明本發明的實施形態2中的旋轉刷的旋轉軸的磁化狀態與非磁化狀態的切換的圖。The magnetized portion 29 having the above-described configuration rotates the hard magnetic material 29a in the rotating shaft 25 along the inner peripheral surface of the rotating shaft 25 in accordance with the rotation of the switching portion 29b, whereby the rotating shaft 25 is magnetized or non-magnetized. . FIG. 11 is a view for explaining switching between a magnetized state and a non-magnetized state of a rotating shaft of the rotating brush in the second embodiment of the present invention.
磁化部29伴隨著切換部29b的旋轉,使旋轉刷4的旋轉軸25內的硬磁性體29a沿旋轉軸25的內周面進行旋轉滑動。由此,磁化部29如圖11所示,使硬磁性體29a的各磁極(N極及S極)的端部與旋轉軸25之中夾著非磁性軸部25b而分離的一對磁性軸部25a接觸。其結果為,磁化部29使所述一對磁性軸部25a磁化為N極及S極,將整個旋轉軸25自非磁化狀態切換為磁化狀態(圖11中,利用虛線表示磁力線的圖像)。The magnetized portion 29 rotates and slides the hard magnetic material 29a in the rotating shaft 25 of the rotating brush 4 along the inner circumferential surface of the rotating shaft 25 in accordance with the rotation of the switching portion 29b. As a result, as shown in FIG. 11, the magnetized portion 29 is a pair of magnetic shafts in which the end portions of the magnetic poles (N pole and S pole) of the hard magnetic material 29a are separated from the rotating shaft 25 by the nonmagnetic shaft portion 25b. The portion 25a is in contact. As a result, the magnetized portion 29 magnetizes the pair of magnetic shaft portions 25a into the N pole and the S pole, and switches the entire rotating shaft 25 from the non-magnetized state to the magnetized state (in FIG. 11 , the broken line indicates the image of the magnetic line of force). .
又,磁化部29伴隨著切換部29b向與所述磁化狀態的情況不同的位置的旋轉,使旋轉軸25內的硬磁性體29a沿旋轉軸25的內周面旋轉滑動。由此,磁化部29如圖11所示,使硬磁性體29a的各磁極的端部分別跨越磁性軸部25a及非磁性軸部25b而接觸。由此,形成由硬磁性體29a及磁性軸部25a構成的磁性閉合電路(圖11中,利用虛線表示所述磁性閉合電路中的磁力線的圖像)。其結果為,磁化部29消除一對磁性軸部25a的磁化狀態,而將整個旋轉軸25自磁化狀態切換為非磁化狀態。Further, the magnetized portion 29 rotates the hard magnetic body 29a in the rotating shaft 25 along the inner peripheral surface of the rotating shaft 25 in accordance with the rotation of the switching portion 29b at a position different from the magnetized state. As a result, as shown in FIG. 11, the magnetized portion 29 contacts the end portions of the magnetic poles of the hard magnetic material 29a across the magnetic shaft portion 25a and the non-magnetic shaft portion 25b. Thereby, a magnetic closed circuit composed of the hard magnetic body 29a and the magnetic shaft portion 25a is formed (an image of magnetic lines of force in the magnetic closed circuit is indicated by a broken line in FIG. 11). As a result, the magnetizing portion 29 cancels the magnetization state of the pair of magnetic shaft portions 25a, and switches the entire rotating shaft 25 from the magnetized state to the non-magnetized state.
另一方面,本發明的實施形態2的洗淨液噴射方法除了藉由所述磁化部29而進行的旋轉刷4的旋轉軸25的磁化狀態與非磁化狀態的切換方法以外,與實施形態1的洗淨液噴射方法相同。On the other hand, in the cleaning liquid spraying method according to the second embodiment of the present invention, in addition to the method of switching the magnetization state and the non-magnetized state of the rotating shaft 25 of the rotating brush 4 by the magnetizing portion 29, The cleaning solution is the same.
具體而言,在實施形態2的洗淨液噴射方法的磁化步驟中,磁化部29在洗淨製程的鋼板洗淨期間,根據操作者對切換部29b的旋轉操作,使旋轉刷4的旋轉軸25內的硬磁性體29a旋轉滑動,而如圖11所示使硬磁性體29a與旋轉軸25之中的磁性軸部25a接觸。由此,磁化部29使磁性軸部25a磁化,而使整個旋轉軸25為磁化狀態。此時,洗淨液噴射裝置21使存在於噴灑配管2的內部的洗淨液17中的磁性夾雜物19吸附至藉由磁化部29而磁化的旋轉軸25(參照圖4),由此,將洗淨液17與磁性夾雜物19加以分離而自噴灑配管2內的洗淨液17去除磁性夾雜物19。Specifically, in the magnetization step of the cleaning liquid spraying method of the second embodiment, the magnetizing portion 29 rotates the rotating brush 4 in accordance with the rotation operation of the switching portion 29b by the operator during the cleaning of the steel sheet in the cleaning process. The hard magnetic body 29a in the 25 is rotatably slid, and the hard magnetic body 29a is brought into contact with the magnetic shaft portion 25a of the rotating shaft 25 as shown in FIG. Thereby, the magnetized portion 29 magnetizes the magnetic shaft portion 25a, and the entire rotating shaft 25 is magnetized. At this time, the cleaning liquid injection device 21 adsorbs the magnetic inclusions 19 in the cleaning liquid 17 existing inside the spray pipe 2 to the rotating shaft 25 magnetized by the magnetized portion 29 (see FIG. 4). The cleaning solution 17 is separated from the magnetic inclusions 19 to remove the magnetic inclusions 19 from the cleaning liquid 17 in the spray pipe 2.
又,在實施形態2的洗淨液噴射方法的消磁步驟中,磁化部29於在線狀態下的噴灑配管2的管內清掃期間,根據操作者對切換部29b的旋轉操作,使旋轉刷4的旋轉軸25內的硬磁性體29a旋轉滑動,從而如圖11所示,使硬磁性體29a的各磁極的端部分別跨越磁性軸部25a及非磁性軸部25b而接觸。由此,磁化部29消除磁性軸部25a的磁化狀態,而使整個旋轉軸25為非磁化狀態。此時,洗淨液噴射裝置21使藉由磁力而吸附至旋轉軸25的磁性夾雜物19,自藉由磁化部29而切換為非磁化狀態的旋轉軸25脫離至噴灑配管2內的洗淨液17中(參照圖6)。Further, in the degaussing step of the cleaning liquid spraying method of the second embodiment, the magnetizing portion 29 rotates the brush 4 in accordance with the rotation operation of the switching portion 29b by the operator during the in-tube cleaning of the spray pipe 2 in the online state. The hard magnetic material 29a in the rotating shaft 25 is rotatably slid, and as shown in FIG. 11, the end portions of the magnetic poles of the hard magnetic material 29a are brought into contact with the magnetic shaft portion 25a and the non-magnetic shaft portion 25b, respectively. Thereby, the magnetized portion 29 eliminates the magnetization state of the magnetic shaft portion 25a, and causes the entire rotation shaft 25 to be in a non-magnetized state. At this time, the cleaning liquid injection device 21 removes the magnetic inclusions 19 adsorbed to the rotating shaft 25 by the magnetic force, and the rotating shaft 25 that has been switched to the non-magnetized state by the magnetizing portion 29 is detached from the spray pipe 2 In the liquid 17 (see Fig. 6).
