Description
本發明係關於在為了使使用完畢之鍍敷液再生等所使用之結晶槽中，刮掉附著於結晶槽之內表面的結晶物(結晶)之刮除器裝置。 The present invention relates to a scraper device for scraping off crystals (crystals) adhering to the inner surface of a crystallization tank in a crystallization tank used for regenerating a used plating solution or the like.
在將錫鍍敷於鋼板時所使用之鍍敷液(例如，甲磺酸(Methanesulfonic acid)溶液)中，混入有鐵分、水分、淤渣(sludge)。為了藉由將該等混合物(鐵分、水分、淤渣)去除使鍍敷液再生，而使用鍍敷液再生設備(例如，甲磺酸再生設備)。 In the plating solution (for example, a methanesulfonic acid solution) used for plating tin on a steel sheet, iron, moisture, and sludge are mixed. In order to regenerate the plating solution by removing the mixture (iron, moisture, sludge), a plating liquid regeneration device (for example, a methanesulfonic acid regeneration device) is used.
於該鍍敷液再生設備中，藉由濃縮裝置將使用完畢之鍍敷液濃縮至既定之濃度(例如4倍的濃度)之後，將該經濃縮之鍍敷液輸送至被稱為結晶槽(結晶罐)之圓筒形狀之槽，並在結晶槽中將鍍敷液冷卻至既定之溫度(例如-4℃)，而使溶入於鍍敷液中之鐵分結晶。然後，藉由固液分離裝置使鍍敷液中所結晶之鐵的結晶自鍍敷液分離。 In the plating liquid regeneration device, after the used plating solution is concentrated to a predetermined concentration (for example, a concentration of 4 times) by a concentrating device, the concentrated plating solution is transferred to a crystallization tank (referred to as a crystallization tank) The cylindrical tank of the crystal can) is cooled in a crystallization tank to a predetermined temperature (for example, -4 ° C), and the iron dissolved in the plating solution is crystallized. Then, the crystals of the iron crystallized in the plating solution are separated from the plating solution by a solid-liquid separation device.
此時，於結晶槽中，在結晶槽之外表面設置冷卻裝置，而將結晶槽內之溶液冷卻至既定之溫度。自該溶液所結晶之結晶(結晶物)之一部分附著於結晶槽之內表面，使來自冷卻裝置之導熱效率降低，而存在使結晶槽內之溶液無法冷卻、保持於既定之溫度的可能性。於無法將結晶槽內之溶液冷卻、保持於既定之溫度之 情形時，就設備維護與品質確保之觀點而言，將停止溶液朝向結晶槽之輸送或停止結晶槽之後之裝置的運轉。 At this time, in the crystallization tank, a cooling device is provided on the outer surface of the crystallization tank, and the solution in the crystallization tank is cooled to a predetermined temperature. A part of the crystal (crystal) crystallized from the solution adheres to the inner surface of the crystallization tank, and the heat transfer efficiency from the cooling device is lowered, and there is a possibility that the solution in the crystallization tank cannot be cooled and maintained at a predetermined temperature. It is impossible to cool and maintain the solution in the crystallization tank at a predetermined temperature. In the case of the equipment maintenance and quality assurance, the operation of the apparatus after the solution is stopped toward the crystallization tank or after the crystallization tank is stopped.
因此，通常於結晶槽中，為了刮掉附著於結晶槽之內表面之結晶，而於攪拌結晶槽內之溶液之攪拌機的前端設置有刮除器(刮刷器(wiper))(例如，參照專利文獻1、2)。 Therefore, in the crystallization tank, in order to scrape off the crystal attached to the inner surface of the crystallization tank, a scraper (wiper) is provided at the front end of the mixer for stirring the solution in the crystallization tank (for example, reference) Patent Documents 1, 2).
[專利文獻1]日本專利特開2011-11986號公報 [Patent Document 1] Japanese Patent Laid-Open Publication No. 2011-11986
[專利文獻2]日本專利特開2012-246263號公報 [Patent Document 2] Japanese Patent Laid-Open Publication No. 2012-246263
如前述專利文獻1、2所記載，在結晶槽中，為了將附著於結晶槽之內表面之結晶刮掉，而於攪拌結晶槽內之溶液之攪拌機之槽半徑方向前端設置有刮除器。 As described in the above-mentioned Patent Documents 1 and 2, in the crystallization tank, in order to scrape off the crystal adhered to the inner surface of the crystallization tank, a scraper is provided at the tip end of the stirrer in the radial direction of the stirrer in the solution in the crystallization tank.
於結晶槽之內表面為正圓之情形時，由於刮除器均勻地接觸於結晶槽之內表面全周，因此並沒有問題。然而，在結晶槽之經年變化等(因安裝於槽之配管的重量而產生之變形等)，結晶槽之內表面變得不是正圓，而於結晶槽之內表面產生凸部與凹部之情形時，刮除器便無法均勻地接觸於結晶槽之內表面全周，使刮除器在通過凸部時等大幅地反曲變形而無法復原，遂無法確實地刮掉附著於結晶槽之內表面之結晶，而產生附著之結晶的殘留。 In the case where the inner surface of the crystallization tank is a perfect circle, since the scraper uniformly contacts the entire inner surface of the crystallization tank, there is no problem. However, in the aging of the crystallization tank, etc. (deformation due to the weight of the pipe attached to the groove, etc.), the inner surface of the crystallization groove becomes not a perfect circle, and the convex portion and the concave portion are formed on the inner surface of the crystallization groove. In this case, the scraper cannot uniformly contact the entire circumference of the inner surface of the crystallization tank, so that the scraper is largely reversibly deformed when passing through the convex portion, and cannot be restored, and the squeegee cannot be reliably scraped off and attached to the crystallization tank. Crystallization of the inner surface produces residual crystals of adhesion.
其結果，附著於結晶槽之內表面之結晶成長，結晶層之厚度變厚(例如，10mm左右)，來自冷卻裝置之導熱效率降低， 而無法將結晶槽內之溶液冷卻、保持於既定之溫度。如此一來，就品質確保或設備維護之觀點而言，將停止溶液朝向結晶槽之輸送或停止結晶槽之後之裝置的運轉。 As a result, the crystal adhering to the inner surface of the crystallization tank grows, and the thickness of the crystal layer becomes thick (for example, about 10 mm), and the heat transfer efficiency from the cooling device is lowered. It is not possible to cool and maintain the solution in the crystallization tank at a predetermined temperature. As a result, in terms of quality assurance or equipment maintenance, the operation of the apparatus after stopping the delivery of the solution toward the crystallization tank or stopping the crystallization tank will be stopped.
本發明係鑒於上述實情而完成者，其目的在於提供即便在結晶槽之內表面產生有凸部與凹部之情形時，亦可確實地刮掉附著於結晶槽之內表面的結晶物(結晶)之結晶槽之刮除器裝置。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a crystal (crystal) which is surely scraped off an inner surface of a crystal groove even when a convex portion and a concave portion are formed on the inner surface of the crystallizing groove.

根據圖式對本發明一實施形態進行說明，再者，此處以鍍敷液再生設備(例如，甲磺酸再生設備)之結晶槽為例進行敘述。 An embodiment of the present invention will be described with reference to the drawings. Here, a crystal bath of a plating solution regeneration device (for example, a methanesulfonic acid regeneration device) will be described as an example.
圖1係顯示本發明一實施形態之結晶槽之縱剖視圖，圖2係顯示本發明一實施形態之結晶槽之橫剖視圖。 Fig. 1 is a longitudinal sectional view showing a crystallization tank according to an embodiment of the present invention, and Fig. 2 is a transverse cross-sectional view showing a crystallization tank according to an embodiment of the present invention.
如圖1、圖2所示，本發明一實施形態之結晶槽1呈圓筒形狀，且具備有：外筒2；內筒3，其係設置於外筒2之內側；頂壁5a，其覆蓋外筒2與內筒3之上部；及底壁5b，其位於外筒2 與內筒3之下部。結晶槽1例如為SUS(Steel Use Stainless；鋼使用不銹鋼)304製，且板厚為2~6mm。 As shown in Fig. 1 and Fig. 2, a crystallization tank 1 according to an embodiment of the present invention has a cylindrical shape and includes an outer cylinder 2, an inner cylinder 3 which is provided inside the outer cylinder 2, and a top wall 5a. Covering the upper portion of the outer cylinder 2 and the inner cylinder 3; and the bottom wall 5b, which is located at the outer cylinder 2 With the lower part of the inner cylinder 3. The crystallization tank 1 is made of, for example, SUS (Steel Use Stainless) 304, and has a thickness of 2 to 6 mm.
而且，為了冷卻被供給至內筒3內之再生對象的鍍敷液30，於外筒2與內筒3之間隙供給有冷卻液4。 Further, in order to cool the plating liquid 30 to be regenerated in the inner cylinder 3, the coolant 4 is supplied to the gap between the outer cylinder 2 and the inner cylinder 3.
又，為了攪拌被供給至內筒3內之再生對象的鍍敷液30，而設置有攪拌機6。攪拌機6具備有：馬達7，其係設置於頂壁上部；旋轉軸8，其自馬達7而於內筒3內朝下方延伸；及攪拌翼9，其自旋轉軸8朝槽半徑方向延伸。攪拌翼9以旋轉軸8為中心進行旋轉。 Moreover, the agitator 6 is provided in order to stir the plating liquid 30 to be regenerated in the inner cylinder 3. The agitator 6 is provided with a motor 7 provided on an upper portion of the top wall, a rotating shaft 8 extending downward from the motor 7 in the inner cylinder 3, and a stirring blade 9 extending from the rotating shaft 8 in the radial direction of the groove. The stirring blade 9 rotates around the rotating shaft 8.
藉此，於該結晶槽1中，被供給至內筒3內之再生對象的鍍敷液30一邊由攪拌機6所攪拌，一邊經由內筒3而被冷卻液4冷卻至既定之溫度，藉此使融入於鍍敷液30中之鐵分作為結晶物31而結晶於鍍敷液30中。 In the crystallization tank 1, the plating liquid 30 to be regenerated in the inner cylinder 3 is cooled by the agitator 6 while being cooled by the inner cylinder 3 to a predetermined temperature. The iron component incorporated in the plating solution 30 is crystallized in the plating solution 30 as the crystal 31.
此處，如圖2所示，在該結晶槽1中，由於經年變化等，而於結晶槽1之內表面(內筒3之內表面3a)產生凸部3A與凹部3B。凸部3A係結晶槽1之中心軸(旋轉軸8之軸心8a)至結晶槽1之內表面(內筒3之內表面3a)之距離中相對較短的部分。凹部3B係結晶槽1之中心軸(旋轉軸8之軸心8a)至結晶槽1之內表面(內筒3之內表面3a)之距離中相對較長的部分。例如，將旋轉軸8之軸心8a至內筒3之內表面3a之距離的平均值作為基準值，而將旋轉軸8之軸心8a至內筒3之內表面3a之距離中未達基準值的部分作為凸部3A，並將旋轉軸8之軸心8a至內筒3之內表面3a之距離為基準值以上的部分作為凹部3B。 Here, as shown in FIG. 2, in the crystallization tank 1, the convex portion 3A and the concave portion 3B are formed on the inner surface (the inner surface 3a of the inner cylinder 3) of the crystallization tank 1 due to the change over the years. The convex portion 3A is a relatively short portion of the central axis of the crystallizing groove 1 (the axis 8a of the rotating shaft 8) to the inner surface of the crystallizing groove 1 (the inner surface 3a of the inner cylinder 3). The recess 3B is a relatively long portion of the central axis of the crystallizing groove 1 (the axis 8a of the rotating shaft 8) to the inner surface of the crystallizing groove 1 (the inner surface 3a of the inner cylinder 3). For example, the average value of the distance from the axial center 8a of the rotating shaft 8 to the inner surface 3a of the inner cylinder 3 is used as a reference value, and the distance from the axial center 8a of the rotating shaft 8 to the inner surface 3a of the inner cylinder 3 is not up to the reference. The portion of the value is the convex portion 3A, and a portion where the distance from the axial center 8a of the rotating shaft 8 to the inner surface 3a of the inner cylinder 3 is equal to or greater than the reference value is defined as the concave portion 3B.
因此，在該實施形態中，為了刮掉附著於內筒3之內 表面3a之結晶物32(在圖1中予以省略)，而於攪拌機6之槽半徑方向前端設置有刮除器裝置10，該刮除器裝置10具備有：凸部用刮除器12，其用以刮掉附著於凸部3A之結晶物32；及凹部用刮除器14，其用以刮掉附著於凹部3B之結晶物32。 Therefore, in this embodiment, in order to scrape off and adhere to the inner cylinder 3 The crystallizer 32 of the surface 3a (omitted in FIG. 1) is provided with a scraper device 10 at the tip end in the radial direction of the agitator 6, and the scraper device 10 is provided with a scraper 12 for a convex portion. The scraping member 32 for scraping off the convex portion 3A; and the concave portion scraper 14 for scraping off the crystallized material 32 attached to the concave portion 3B.
亦即，若詳細敘述則如以下之內容。 That is, if it is described in detail, it is as follows.
刮除器裝置10具備有：刮除器安裝板11，其涵蓋從結晶槽1之頂壁5a附近至底壁5b附近而設置，被配置於攪拌機6之攪拌翼9之槽半徑方向前端；及自攪拌機6之旋轉方向S之前方朝向後方依序將凸部用刮除器、凸部用刮除器支持板、凹部用刮除器、凹部用刮除器支持板重疊並利用螺栓、螺帽16而被安裝於刮除器安裝板11之凸部用刮除器12、凸部用刮除器支持板13、凹部用刮除器14、凹部用刮除器支持板15。 The scraper device 10 is provided with a scraper attachment plate 11 which is provided from the vicinity of the top wall 5a of the crystallization tank 1 to the vicinity of the bottom wall 5b, and is disposed at the front end of the agitating blade 9 of the agitator 6 in the radial direction of the groove; The scraper for the convex portion, the scraper support plate for the convex portion, the scraper for the concave portion, and the scraper support plate for the concave portion are sequentially overlapped from the front in the direction of the rotation S of the agitator 6 and the bolts and nuts are used. The blade portion scraper 12, the convex portion scraper support plate 13, the concave portion scraper 14, and the concave portion scraper support plate 15 are attached to the scraper mounting plate 11.
圖3係顯示凸部用刮除器12、凸部用刮除器支持板13、凹部用刮除器14、凹部用刮除器支持板15之平面形狀之俯視圖。該等之平面形狀皆為矩形，且縱向上之長度雖相同，但前端方向之長度則各不相同。而且，以可變更、調整前端方向之安裝位置的方式，使螺栓、螺帽16用安裝孔17成為長孔。 3 is a plan view showing a planar shape of the convex portion scraper 12, the convex portion scraper support plate 13, the concave portion scraper 14, and the concave portion scraper support plate 15. The planar shapes are all rectangular, and the lengths in the longitudinal direction are the same, but the lengths in the front end directions are different. Further, the bolts and the nuts 16 are formed into long holes by the mounting holes 17 so that the mounting positions in the distal end direction can be changed and adjusted.
而且，凸部用刮除器12係用以刮掉附著於凸部3A之結晶物32之刮除器。例如，為硬質鐵氟龍(註冊商標)製，且厚度為0.5~3mm。凸部用刮除器支持板13具有如下之支持板：用以於凸部用刮除器12刮掉附著於凸部3A之結晶物32時，即便該凸部用刮除器12因來自結晶物32之抵抗力而反曲變形，仍可使其復原。例如，為硬質鐵氟龍(註冊商標)製，且厚度為1~6mm。 Further, the convex portion scraper 12 is used to scrape off the scraper attached to the crystals 32 of the convex portion 3A. For example, it is made of hard Teflon (registered trademark) and has a thickness of 0.5 to 3 mm. The convex portion scraper support plate 13 has a support plate for scraping off the crystallized material 32 attached to the convex portion 3A by the convex portion scraper 12 even if the convex portion scraper 12 is derived from the crystal The resistance of the object 32 is reversed and deformed, and it can still be restored. For example, it is made of hard Teflon (registered trademark) and has a thickness of 1 to 6 mm.
另一方面，凹部用刮除器14係用以刮掉附著於凹部 3B之結晶物32之刮除器。例如，為硬質鐵氟龍(註冊商標)製，且厚度為1~4mm。凹部用刮除器支持板15具有如下之支持板：用以於凹部用刮除器14通過凸部3A時，在大幅地反曲而變形後可使其復原。例如，為不銹彈簧鋼製，且厚度為0.2~0.6mm。 On the other hand, the concave portion scraper 14 is used to scrape off the concave portion 3B of the crystal 32 scraper. For example, it is made of hard Teflon (registered trademark) and has a thickness of 1 to 4 mm. The concave portion scraper support plate 15 has a support plate for recovering the convex portion 3A when the concave portion scraper 14 passes, and is deformed after being largely recurved. For example, it is made of stainless steel and has a thickness of 0.2 to 0.6 mm.
而且，就保持來自冷卻液4之導熱效率之觀點，與抑制刮除器裝置10之損耗或防止攪拌機6之過負載之觀點而言，凸部用刮除器12與內筒3之內表面3a之間隙，較佳為：在凸部3A中自旋轉軸8之軸心8a至內筒3之內表面3a之距離中最短的位置，使間隙成為0mm~1.5mm，而凹部用刮除器14與內筒3之內表面3a之間隙，較佳為：在凹部3B中自旋轉軸8之軸心8a至內筒3之內表面3a之距離中最長的位置，使間隙成為0mm~1.5mm。 Further, from the viewpoint of maintaining the heat conduction efficiency from the coolant 4, the convex portion scraper 12 and the inner surface 3a of the inner cylinder 3 from the viewpoint of suppressing the loss of the scraper device 10 or preventing the overload of the agitator 6 The gap is preferably the shortest position among the distance from the axial center 8a of the rotating shaft 8 to the inner surface 3a of the inner cylinder 3 in the convex portion 3A, so that the gap becomes 0 mm to 1.5 mm, and the concave portion scraper 14 The gap with the inner surface 3a of the inner cylinder 3 is preferably the longest position among the distance from the axial center 8a of the rotating shaft 8 to the inner surface 3a of the inner cylinder 3 in the concave portion 3B, so that the gap becomes 0 mm to 1.5 mm.
藉由前述之構成，在該實施形態中，即便在結晶槽1之內表面(內筒3之內表面3a)產生有凸部3A與凹部3B之情形時，亦可確實地刮掉附著於結晶槽1之內表面(內筒3之內表面3a)之結晶物(結晶)。 According to the above configuration, even in the case where the convex portion 3A and the concave portion 3B are formed on the inner surface of the crystal cell 1 (the inner surface 3a of the inner tube 3), the adhesion to the crystal can be surely scraped off. Crystallization (crystallization) of the inner surface of the groove 1 (the inner surface 3a of the inner cylinder 3).
在壓抵於結晶槽1之內表面之類型的刮除器中，難以使刮除器追隨內筒3之凹凸。另一方面，本發明藉由配合凹凸而對與內筒3之內表面3a之間隙進行調整，可容易地使刮除器追隨內筒3之凹凸。 In the scraper of the type pressed against the inner surface of the crystallization tank 1, it is difficult to cause the scraper to follow the unevenness of the inner cylinder 3. On the other hand, in the present invention, by adjusting the gap with the inner surface 3a of the inner cylinder 3 by fitting the unevenness, the scraper can easily follow the unevenness of the inner cylinder 3.
再者，在前述之實施形態中，雖於攪拌機6之旋轉方向S之前方設置凸部用刮除器12，並於攪拌機6之旋轉方向S之後方設置凹部用刮除器14，但亦可使該設置順序相反。 Further, in the above-described embodiment, the convex portion scraper 12 is provided before the rotation direction S of the agitator 6, and the concave portion scraper 14 is provided after the rotation direction S of the agitator 6, but it is also possible Make the order of the settings reverse.
