(7) (7)1326614 基本上來說，導軌6係如同第7圖中以斷面所示般， 令Η型鋼製成的一對軌道本體7，擺成其個別的槽都朝向 側面，以左右離間的方式進行配置，再利用於縱向方向離 間設置的軌道連結板8熔接固定這些本體7後形成導軌。 又，用固定螺栓9將軌道連結板8的左右端固定於池底4 的方式，來鋪設固定軌道本體7。 軌道本體7各外側的頂面，熔接固定著移動地板]〇 。如說的更詳細點，前頭側軌道Α係如第2圖所示，其 前端部係藉由軌道托架11固定於前端的端壁2上，同時 ，以軌道連結板8纏繞在池底4前端上的方式來固定其後 端部。在此前頭側軌道A上，第3承載槽輪I 2係固定於 前側的較低位置之寬度中間，同時，第1承載槽輪1 3係 透過托架14，固定於比其略爲後側的較高位置之寬度中 間。 同前頭側軌道A的後側則連設著多條的中間軌道c， 這些中間軌道C後端之後側則連設著尾側軌道B，而第2 承載槽輪15係透過此軌道B來固定的。同槽輪15係透過 托架]6來固定的》 又，各移動地板1 〇係，由軌道本體邊緣稍微往前延 伸的頂端，形成平面傾斜的縮短狀’例如，於第8圖的左 下圖的前頭側軌道A之中’移動地板1 〇的後端係形成爲 比軌道本體還要短的樣子，其後側中間軌道C側的移動地 板I 〇之延伸部分，則放在前頭側軌道A的桿本體上，並 留下細微的空隙相對著。多條連設的中間軌道C之間也一 -10- (8) (8)1326614 樣，同軌道C的移動地板1 〇的後側有被縮短，爲了讓其 連續下去’比其後側的軌道C之移動地板1 0，則放到了 上面去。中間軌道C與尾側軌道Β間的關係亦同，像這 樣1個連續的移動地板1 0，則於導軌6上左右一對地構 成著。 像這樣成爲連續狀的移動地板〗0之前端與後端部係 ’後述的移動輪於前進端與後進端的地方，是比同移動地 板1 〇更加陷入於本體上以形成斜度1 7。其樣子則以放大 圖的形式，取出於第8圖的下欄以進行說明。此斜度17 係爲了’從刮集狀態要進入復位狀態時以及從復位狀態要 進入刮集狀態時，利用使台車產生乘上阻力的方式，讓污 泥刮刀先作用而設置的。 導軌6內如第7圖所示，以身爲上方朝向槽的角鋼之 內軌道19通過軌道連結板8上的方式來進行固定，此內 軌道1 9係連續鋪設於，第2圖的第3承載槽輪]2後方至 第2承載槽輪]5前方位置之間。又’內軌道19的前後端 則設有下降傾斜狀的軌道片1 9a，後述的牽引傳達手段則 不會卡住可以很圓滑地進行引導。又，如第7圖所示，內 軌道I 9的兩橫端則立設著’附屬的牽引傳達手段2 6用的 脫落控制片】9b。此控制片1 9b係於縱向方向相隔一定的 間隔進行設置’亦可採用較長的控制片。 又，爲了不讓從上方而來的污泥侵入導軌6內，則以 軌道蓋20可自由脫裝的方式安裝於軌道本體7，7間的頂 端，此寬度間有著槽2 0 a。亦可讓後述的台車側具備，用 -11 - (9) (9)1326614 來除去此槽20a內污泥的刮刀。此刮刀亦可是類似活節鏈 條的構件。 台車22係具備台車本體23，同本體23係由前部a 與後部b構成，這些部份都配置於第7圖所示的槽向上的 槽型鋼處，使用如第2圖之凸緣24，以可自由脫裝的方 式連結此前後，形成纖細的單一條型的軀體。 如第4圖的立體圖所示，承台26係一體地固裝於台 車本體23的前部上。此承台26於左右具備形成爲水平台 狀的軸承安裝台27，以及在前端部則具備往直角下垂般 的一體形成之端板2 8，再用內補強板2 9與上補強板3 0 補強這些部份，同時，用來確保於刮集的緊急狀況，撞上 第2圖之導軌6上所具備的安全停止器（進退調節式）3] 時之安全的台車側撞擊板3 2，則以左右一對的形式設置 於端板2 8的前面。 用來以前後的位置關係固定能使前述移動地板1 0受 到外側方向而來的撞擊之側滑輪3 4，以及能使軌道本體7 的腹板受到下方而來的撞擊之防止上浮滑輪（附托架 3 6 ) 3 5之滑輪托架3 7，則固設於左右的承台2 6之底側。 又’端板2 8與蓋子支撐3 8之間，則以可自由脫裝的方式 裝設著’保護後述的軸承等免受污泥侵害的側蓋3 9。又 ’ ^板2 8的下部背面則以可自由脫裝的形式，裝備著用 $ @去如第3圖所示的導軌6上面與槽內污泥的軌道刮刀 40 〇 it些構成於台車後端部也幾乎都是一樣的，在此則記 -12 - (10) (10)1326614 上相同符號後省略其說明。 台車本體23的承台26後方的後方側’如第4圖所示 ，一體地突設了車軸4 ]的軸安裝板4 2 ’則以能從側面用 螺栓固定的形式進行了安裝，移動輪4 3則以可自由旋轉 的方式，裝備於同車軸41之左右一對的軸安裝板上。此 移動輪4 3則會於前述移動地板]0上轉動。 構成左右一對的中間輔助輪4 5則以無限定的樹脂輪 的形式，裝備於台車本體2 3的前後接合部份附近。 另一方面，如第1圖至第3圖所示，左右一對的軸承 5 2則以其軸心向著池寬方向，可自由脫裝的形式固定於 前後的承台2 6之各軸承安裝台2 7上。實心狀（或管狀亦 可）的旋轉軸53則以通過這些軸承52，兩側伸出的狀態 被裝備著。藉由於此旋轉軸5 3的兩端插通刮刀管5 4後， 左右一對的污泥刮刀5 5則利用固合購件5 6固裝成可自由 地插脫的狀態。污泥刮刀5 5係，越過由刮刀管5 4突設的 連結帶5 7之下緣與外緣部’裝備著抓扒橡膠帶5 9。又， 爲了令其可對應既設導軌6 0進行旋轉，導軌6 I係以可調 節高度的方式，配備於前後的刮刀本體5 8的背面下部。 另一方面’對應前側旋轉軸5 3的軸承5 2間的部位上 ’如第5圖與第6圖所示，爲了令短的受力臂63可隨旋 轉軸53 —起旋轉’而左右一對地突設著，同時，通過彎 曲支點軸64往局處伸長的前聯鎖臂65，則以可前後地搖 動的方式軸支於同受力臂63間。此受力臂65的上部則具 備著，可調節重量的配重6 6，同時，爲了令此配重6 6以 -13 -

[Prior Art] In the treatment tanks such as sedimentation tanks, a large number of scrapers are provided on the chain of the circulating motion. When the scraper passes through the bottom of the tank, the sludge at the bottom of the tank is scraped and transported to the sludge tank. For the reason that the structure is complicated and the cost is not the same, recently, a trolley equipped with a sludge scraper that can move up and down has been replaced in place of the device, and a sludge scraping device that moves forward and backward along the guide rail laid on the bottom of the pool has appeared. Such a sludge scraping device has the advantages of being relatively simple in construction and relatively inexpensive. SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] However, such a sludge scraping device allows a trolley equipped with a plurality of moving wheels to advance and retreat freely on a guide rail, and the drive transmitted through the pool is conveyed by a wire rope or the like. The means enable it to be freely driven to advance and retreat, and, in general, the drive is advanced and retracted, and the sludge scraper equipped with the trolley is usually freely movable between the vertical scraping state and the raised reset state. Switch. In such a sludge scraping device, the guide rails are arranged along the two side walls, and at the same time, the wide trolley is equipped with a space spanning the side walls, so that the device forms a large-scale form and reduces the cost. Also not ideal - 4 - (2) 1326614 ο Again, in the past, the processing pool may not be able to fall back and forth from the front and rear ends to the front, but the style at this time, the scope of the simplified However, the height of the blade of the scraping device of the type is from the sputum, and it is conceivable that the snorkeling property is high, and the stagnation is high. The present invention simplifies the apparatus as a whole to provide a scraping device for the construction of the time zone without rolling up the sludge. In addition, when the other sludge scraping device has a long stroke, the length of the sludge scraping device becomes longer, for example, it is completely processed. It is equipped with a sludge scraper, which is placed in the body of the trolley in the sludge tank, and the basic structure of the basic device is constructed. In the case of the above-mentioned smear, for example, it is necessary to set aside the past, that is, when it is going forward, it will be rolled up. 'Improve the purification process and transport it back. The purpose of the order is that the front and rear of the trolley are short, but the retreat will also become longer. When the scraping cycle flows into the treatment tank, a large amount of sewage flows into the treatment tank. Extend the trolley and divide the rear sludge into several scraping methods. The above-mentioned large-scale flat rectangular frame has its limit, and when the type of the sedimentation tank that is switched to the upper and lower sides of the mud scraper is set as the object, the sludge is set to be 600 mm or more and is easy to roll up. Mud, because this raw sludge may be taken out by the overflow of the water in the pool, the invention of the purification treatment problem aims to achieve the goal of reducing costs and scraping the device at a later time. The other purpose is to increase the efficiency of the sludge, and the sludge that is effectively activated by the sludge purification treatment is simplified and arranged in the circular sinking source pool -5- (3) (3) 1326614 A scraping device that provides a sludge that is cheaper and ensures reliable operation. [Means for Solving the Problems] In order to solve the above problems, the invention described in claim 1 is characterized in that it has a side wall facing each other and a front and rear end walls orthogonal thereto, and has one end at the same time. The sinking tank and the aeration tank of the sludge tank are shaped like a flat rectangular processing tank, and the longitudinal direction of the front and rear direction is laid by the center of the two side walls, and the same rail is used. After the telescopic movement of the eye lj, the trolley with the moving wheel is set to 'simultaneously' in a manner that can be switched up and down to form a sludge scraper in a lowered scraping state and an elevated reset state, and the equipment on the same vehicle will be immersed in The sludge on the left and right sides of the guide rail is scraped to the sludge scraper in the direction of the sludge tank; on the treatment tank, there is a drive unit that continuously drives the rotary drive wheel, and can switch the rotation direction in a positive and negative direction, and is hung around the drive wheel and equipped The traction means of the direction change wheel in the treatment tank is configured to drive the traction trolley in the forward or backward direction after switching the sludge scraper to the upper or lower rotation . In the scraping device of the sludge or the like described in the scope of the invention, the scraping device such as sludge is configured such that the sludge scraper is equipped at least in the invention. At the front and rear ends of the trolley, the sludge scraper on the rear side is scraped to the front sludge by the sludge scraper at the rear end by using the sludge scraper on the front side, and then scraped forward.

As shown in Fig. 4, the shaft mounting plate 4 2 ' in which the axle 4 is integrally protruded as shown in Fig. 4 is attached to the side by bolts, and the moving wheel is mounted. 4 3 is mounted on a pair of left and right shaft mounting plates of the same axle 41 in a freely rotatable manner. This moving wheel 43 will rotate on the aforementioned moving floor]0. The intermediate auxiliary wheels 45 constituting the pair of right and left are provided in the vicinity of the front and rear joint portions of the trolley body 23 in the form of an unrestricted resin wheel. On the other hand, as shown in Fig. 1 to Fig. 3, the pair of right and left bearings 5 2 are fixed to the front and rear of the bearing plates 26 with their axial centers facing the pool width direction. Taiwan 2 7 on. The solid shaft (or tubular shape) of the rotating shaft 53 is equipped in such a manner that the bearings 52 are extended from both sides. After the both ends of the rotating shaft 53 are inserted into the doctor blade 5 4, the pair of left and right sludge scrapers 5 5 are fixed by the fixing member 56 to be freely inserted and removed. The sludge scraper 5 5 is equipped with a grip rubber band 59 over the lower edge and the outer edge portion of the connecting belt 57 protruding from the doctor blade 54. Further, in order to make it rotatable in accordance with the existing guide rail 60, the guide rails 6 I are provided at the lower portion of the back surface of the front and rear scraper bodies 58 in an adjustable height. On the other hand, 'corresponding to the portion between the bearings 52 of the front side rotating shaft 53, as shown in Figs. 5 and 6, in order to make the short force receiving arm 63 rotate with the rotating shaft 53'. At the same time, the front interlocking arm 65 which is extended to the office by the bending fulcrum shaft 64 is axially supported between the same force receiving arms 63 so as to be swingable forward and backward. The upper part of the force-receiving arm 65 is provided with a weight-adjustable weight 6 6 , and at the same time, in order to change the weight 6 6 -13 - (11) (11) 1326614 vertical line 6 7 as a reference, Then, the lower end portion of the force receiving arm 65 forms a semicircular recess 68 having an inner diameter larger than the diameter of the rotating shaft 53. The front and rear lower ends 69 alternately touch the rotating shaft 53. This is because, as shown in Fig. 5, since the counterweight 6 6 is closer to the front than the vertical line 67, the accompanying force of the forward rotation acts, whereby the scraper 5 5 tends to be stable toward the scraping state. On the other hand, as shown in Fig. 6, since the counterweight 6 6 is closer to the rear than the vertical line 67, the companion force of the backward rotation acts "by this, the blade will be lifted (reset state). becoming steady. Further, the rear interlocking arm 71 is a member having a shape similar to that of the front interlocking arm 65, and is erected from the rotating shaft 53 in a fixed manner. The front interlocking arm 6 5 and the rear interlocking arm 7 1 are respectively coupled to one end of the length-adjustable interlocking link 72. The lower end of the other end of the interlocking link is coupled to the advancing and retracting piece 73 which advances and retreats horizontally and backward. The advancing and retracting piece 73 is provided with a contact portion 74. In the vicinity of the front and rear of the advancing and retracting piece 7 3, these members are integrally fixed to the corner bar-shaped advancing and retracting slider 75 which advances and retreats at the center bottom between the widths of the bogie body 23 as shown in Fig. 4 . The advancing and retracting slider 75 is a pair of front and rear members. These members are guided in the corner holes of the resin slider holder 77 provided in the bobbin body 2, and are freely advanced and retracted. The slider holder 77 is held in a freely detachable state by the upper pad 78. Further, between the front and rear sliders 75, as shown in Fig. 1, they are connected by a relay link 79 made of one round bar. 80 is a front stop, and 8 is a rear stop, which is disposed in front of and behind the two sides of the trolley body 2 -14 - (12) (12) 1326614 through the bracket 82'. By the contact portion 74 hitting the stoppers 80, 81, the blade is set to the scraping state and the reset lifting state. On the other hand, as shown in Fig. 2, the center of the pool width on the corresponding pool is provided with a driving wheel 85 as a load sheave for the joint chain, and the same drive wheel 8 is driven by a motor of the reducer motor. To control the forward and reverse rotation. This is reversed by a limit switch not shown. The traction means 8.6, which is the hinged chain of the driven wheel 8 5, is coupled to the link anchor 8 via the first carrying sheave 13 as shown in Fig. 4. On the other hand, the rear connecting rod anchor is also connected to the other end of the traction transmitting means 86, and the same means 86 is inserted into the guide rail 6 through the second carrying sheave 5 as shown in Fig. 2 Guided by the inner rail 19, the front side of the track 19 is re-rolled by the third carrying sheave 12 and then the original drive wheel 85 is wound up. As shown in Fig. 4, the front side of the trolley body 2 3 is The erecting post 8 8 is as shown in Fig. 3, and the struts 8 9 are transmitted through the table 8 8 ox . The scum scraping device is configured to pass through the struts 89, and the same device is provided with a shovel which floats on the surface of the water surface 90 and is slid to the scum removing device. The high front pillar body is provided. The four pillars of the rear pillar #sbs 92, which are lower than the rear side, are erected on the lower end of the pillar plate 4 Q 93, and are fixed to the pillars shown in Fig. 4 in a detachable manner. 88. The upper end of the rear pillar body 92 and the front pillar body 91 are connected to each other, and the left and right front and rear connecting members 9.5 are connected to each other. Moreover, the upper end of the pillar 8 9 is erected in the form of a pair of left and right, -15-(13) (13) 1326614 has the lifting guide 98 of the coil spring 97, and the scum scraping board 99 can be The rod 9 8 is freely raised and lowered. The scum scraping plate 9 9 is made of a hollow material of a rectangular cross section, and at the same time, a foaming material is filled inside to ensure buoyancy. The lowering rod 100 is protruded from the central bottom surface between the widths of the same scum scraping plate 99, and the rod 100 is lowered and guided by the rod guide 〇2 which is suspended by the upper horizontal connecting material 1 〇 1 . One end of the floating cable 30 is connected to the lower end of the rod 100, and the steel cable 103 is passed through the front wheel of the lower cross member 96, and is disposed on the sprockets 1 and 5 of the protruding bracket 104. The upper end of the front front interlocking arm 65. Next, the role of the same device will be explained. Fig. 1 'Fig. 2 and 3 show the state before the end of the scraping. In this state, as shown in Fig. 2, the traction transmitting means 86 is pulled as in the solid arrow F, and the advancing and retracting slider 75 of the fourth drawing connected to the traction means is pulled. The advancing and retracting piece 73 on the same slider 75 is pulled to the front of the fourth figure, and the front interlocking arm 65 is pushed forward through the interlocking interlocking link 72. The front interlocking arm 65 tends to be reversed in the fifth drawing, and is supplied with the forward tendency, and the sludge scraper 55 is kept vertical by the bending arm shaft 64 by the force receiving arm 63. Scratch state. On the other hand, at the rear side, when the advancing and retracting slider 75 of Fig. 4 is pulled forward, the advancing and retracting piece 73 will be passed through the relay link (Fig. 1) 79 attached to the slider. Pulling toward the SU side, the contact portion 74 stops after hitting the rear stop 8]. When the advancing and retracting piece 73 is pulled forward, through the interlocking link 72, it will become the standing state as shown in the middle figure of Fig. 2, and at the same time, the sludge scraper 5 5 on the rear side will also be -16-( 14) 1326614 ί: State companion 1 00 5: The opposite movement is caused by the rotation of R and is subjected to a scraping state that is defined as a vertical direction. This is the reason why the state of the scratched state is maintained in accordance with the stroke of the second figure / S of the second figure. On the other hand, the front interlocking arm 65 is in a forward-rear shape when scraping, so the float-slip steel cable 03 of Fig. 2 is pulled forward, and the pulling action is transmitted through the sheave. After 〇5, the lowering rod of Figure 3 will be pulled down, and this action will compress the coil spring 9 7 while the upper scum scraping board 9 9 will be pulled below the water surface of 90, not going to The scum is scraped back in the direction of the F direction and returned to the original position. Thereafter, for the traction means 86, the source of the limit switch is switched to the reverse rotation (turning to the right in Fig. 2). Further, although it is configured such that the trolley side impact plate 32 will hit the front side safety stop 3 1, this is only a function in an emergency, and generally, the function of the aforementioned switch causes the trolley 22 to stop moving forward. . With the aforementioned reversal, as in Fig. 2, the traction means 86 will be pulled in the direction of the dashed arrow 'at the same time, and guided via the third carrying sheave 2 and along the inner rail 19 in the guide rail 6 Leading, thereby being pulled toward the front. Further, the guiding means 86, which is rotated upward via the rear second carrying sheave 15, is pulled back. Thereby, the rear advancement and retraction sliders 7 5 act in the same direction, and at the same time, not only the rear advancement and retraction sheets 73 have passed through the relay link 79, but also the front advance and retreat sheets 73 are simultaneously pulled rearward. As a result, the front and rear interlocking links 72 move rearward together, and the front interlocking arm 6 5 and the rear interlocking 7 attached to the links are reversed. Thereby, the front interlocking arm 6 5 will be switched to the rear of the counterweight 6 6 as shown in Fig. 6, and then through the -17-(15) (15) 1326614 force arm 63 ' as shown in Fig. 2 The rotating shaft 53 generates an interlock to cause the sludge scraper 55 to be in a raised reset state. The rear interlocking arm 71 will also be reversed by the interlocking link 72, and the subsequent sludge scraper 5 5 will be forwarded to the raised reset state. However, according to these effects, the front advancement and retraction piece 7 3 will hit the front stopper 8 Q as in the upper diagram of Fig. 2, so that the integral interlock mechanism will be stopped and locked in the reset state, but before that, the trolley 22 may also start to retreat because of the subsequent force. Therefore, at the moment before the end of the scraping state, the front moving wheel 42 is first slightly lowered from the front end of the moving floor], and conversely, in order to let the moving wheel pass over the moving floor when retreating, first let it have Resistance, whereby the force generated by the traction means 86 will cause the trolley 22 to retreat, so the trolley will not act first, and the interlocking arm 6 5, 7 ] will be used first to achieve the sludge. The scraper 5 5 switches first and creates an interlock, after which the trolley 22 will begin to confirm the operation of the action. This is also the case when switching from the reset state to the scraping state. Further, on the side of the scumming scraping plate 99, since the front interlocking arm 65 is turned backward, the solid steel cable 103 becomes slack, and at the same time, the repulsive force of the spring 97 acts on the water surface to become floating. The scum scraping state. Therefore, after the 'current side moving wheel 42 is multiplied by the moving floor' 0, the traction transmitting means 86 will be continuously driven according to the above-mentioned action, so that the front and rear sludge scraping blades 5 will be kept raised to the state of FIG. The R direction is restored to the original position, and at the same time 'the surface scum of the water surface is scraped to the direction of the scum removal device by the scum scraping plate 99. When the sludge scraping device is returned to the rear end, the drive source is switched in the opposite direction (leftward -18 - (16) (16) 1326614 revolutions in Fig. 2) due to the activation of the limit switch. Thereby, the front and rear sludge scrapers 5 5 are switched to the vertical scraping state (Fig. 2, lower drawing). In this state, the sludge scraper 5 5 on the front side becomes as shown in the middle section, and is in a standby state at a position slightly behind the sludge scraper 5 5 at the rear. Therefore, the operation is performed by the sludge scraper 5 5 at the rear when the scraping is completed, which is indicated by the solid line. On the other hand, if the stroke S is advanced by only the rear sludge scraper 55 of the lower drawing of Fig. 2, the state of the rear sludge scraper shown by the solid line in the middle section will be obtained. That is, the sludge in the rear area will be transported into the sludge tank 3 by a two-stage scraping operation. On the contrary, tongue! The advance and retreat stroke of the J-set device will become approximately half. Therefore, as indicated by the imaginary line in Fig. 1, the third scraper is disposed between the sludge scrapers 5 5 before and after, and further, four or more scrapers can be freely determined. These scrapers will have an interlocking relationship. Moreover, when the device is switched to the scraping state after the retreat, the scum scraping plate 9 9 is pulled down, and the scum is not scraped back to the left direction of the second drawing, but sinks to the surface of the water to the F direction. Reset. Further, in the above embodiment, the joint chain is used as the traction means ‘but it is also possible to use a rope type member such as a belt or a steel cable. Further, regarding the above-mentioned trolley body, the groove may be directed downward, and a member such as a semicircular pipe may be used. In particular, 'in order to allow it to have a simple structure, but the settled sludge does not accumulate, as shown in Figure 9, 'using a mountain or angled steel body Π0, can also be used Same as the body 1 〇 has a bottom part of this]] 〇 one body stamping aged members. Further, as shown by an imaginary line in the same figure, -19-(17) (17) 1326614, a square tube is used and the corner portion is directed upward. As shown in the same figure at the same time, it is also possible to integrally weld two angle steels into a rail body which is entangled with each other, and form a guide rail 12 in a pair of right and left. In the foregoing embodiment, the sludge scraping device with the scum scraping device is described, but there is also a scum scraping device, and the scraping device is formed in the form of a single sludge scraping device. Happening. The above-described truck body 23 is formed in an open state as shown in Fig. 4, and the front top cover 1 〇 7 or the rear top cover (not shown) can be equipped to be freely detachable. The sludge scraper 55 is provided in two front and rear stages, but may be three pieces. Further, there may be cases where a large number of sheets such as 4, 5, and 6 sheets are used. The implementation form equipped with 6 sludge scrapers 5 5 is shown in Figure 1-1 and Figure 11. L is the pitch of the sludge scraper 5 5, and s is the forward and backward stroke ’ S system is set longer than L. Further, the "fouling removing device" 20 is disposed at a position away from the water surface on the right side of the scum scraping plate 99 in the upper drawing of Fig. 1 . The same device]20 series has the function of 'floating the side of the fixed angle groove BU between the side walls 1', and it can be swallowed because it squats more than the water surface 9 〇. The scum that comes from it. The same device system uses a conduit skimmer, and other methods can be used. Regarding the aforementioned sludge scraper 55', although in Fig. 2, a relatively high scraper of a height of about 5 〇〇 to 60 0 mm is used, but the height is lowered to 5 〇 to 400 mm, especially in the final precipitation. In the device of the nth figure in which the pool is the object, the barrel of the squeegee is set to a range of 50 to 300 mm], so -20-(18) (18) 1326614 can effectively prevent floating pollution accompanying advance and retreat. The mud is rolled up. The ideal height of the blade 5 5 is about 200 mm. The forward and backward speed is set to be higher than the standard forward speed of the previous blade (0. It is about 3 m / min) slower about 〇% of 0 _ 2 7 m / min. In this way, the floating sludge will not be scraped. However, if the advancement speed of the sludge scraper 55 is set to be slow, it is conceivable that the scraping amount may be reduced. In the present invention, in addition to the original sludge scraper 5 5 disposed at a predetermined interval in front and rear, the front side of the auxiliary scraper 1 2 1 may be settled by the rectifying plate, that is, in the past The first and second sludge scrapers 5 are counted from the side, and the scrapers that can move up and down are arranged to ensure the amount of scraping. The amount of scraping is ensured by the presence of the auxiliary scraper 112, and the stroke S is set corresponding to the active state holding time. Therefore, the active bacteria transported back to the sludge can be sent to aeration in a living state, in order to Purified and used effectively. In the first picture, the height adjustment plate 1 2 3 is attached to the sludge scraper 5 5 at the front end. With the difference of the splash pool, the scraping amount of the sludge scraper 5 5 sometimes needs to be more. It is to make it able to cope with this need. Further, at the top end of the same plate 1 2 3, a long protruding strip 124 for preventing the curling is formed in the width direction of the pool. In the third embodiment, an embodiment of a roll-up prevention plate 26 made of a material such as angle steel is attached to the front side of the doctor blade 54. The same plate] 26 is attached to the pull bar 127 which is erected obliquely forward by the doctor blade 54. It is also possible to make the same plate 126 centered on the axis 28, and adjust the angle and adjust the height back and forth. Also, a semicircular tube can be used for this plate 126. Also, as shown in the figure on the right, the trolley body 2 3 is made of angle steel and has a roof shape. It not only functions as a machine - 21 (19) 1326614, but also serves as a sludge. The function of the cover that will flow to the left and right. 1 2 9 brackets for bearing. Fig. 14 is a view showing another embodiment for preventing the sludge from being rolled up. The sludge scraper 5 5 is disposed on the rear side of the doctor blade 54. By forming the front region, the rolled up portion will be as shown by the arrow, inverted, and then reduced and eliminated. Further, an inverted guide plate 130 may be protruded from the front side of the peripheral portion of the doctor blade 54. The fifth embodiment shows another embodiment. In the same figure, the sedimentation tank is regarded as the final sedimentation tank. The same sedimentation tank system has the left and right side walls I and the front and rear upstream end walls 2, and the edge of the bottom wall 4 in the flow direction has the sludge tank 3. The upstream end wall 2 is provided with an inflow control wall 131 to which a plurality of inflow ports are attached, and the mixed liquid from the inflow passage is introduced into the pool after passing through the inflow ports. ] 3 2 is a rectifying plate having a plurality of small holes, and is provided in a form opposed to the upstream end wall in order to further rectify the mixed liquid. Sometimes the same rectifier board is not set]32. The final sinking source system like this, when it encounters a large amount of rainfall and flows into the apex, is opposite to the short-circuit flow generally flowing through the upper layer as indicated by the arrow T, because the temperature causes the temperature to become lower and the density becomes slightly larger. The mixture does not fall immediately, but will be in the form of a density flow as an inertial flow, while exhibiting a gentle downward tendency like the arrow Μ in Fig. 5, while being induced in the downstream direction, and then at the downstream end. The front of the wall often turns upside down. When a density flow like this occurs, not only the sedimentation efficiency will be low, but also the floating flotation will follow the floating sludge floc as it flows to the outflow region of the pool, causing these flocculation to occur. The object passes through the overflowing -22- (20) (20) 1326614 above the flow of the annoying problem. In view of such an actual situation, 'in this embodiment, the density flow can be suppressed with a simple effect, and the sludge outflow phenomenon at the initial stage of the inflow can be utilized while preventing the outflow of the sludge floc. The method is to achieve early recovery of activated sludge, and the above problems are not caused by inhibiting the occurrence of sludge flocs themselves. That is, this embodiment is as shown in the fifteenth aspect, in order to make the joint chain 42 slightly rearward from the front end of the guide rail 6 located in the pool, and immediately traverse the entire rear pool from the position in the longitudinal direction.
