下面结合附图对本发明的叠螺污泥脱水机作进一步的说明， 以 4组叠片模 块式叠螺污泥脱水机为例。  The snail sludge dewatering machine of the present invention will be further described below with reference to the accompanying drawings, and four sets of laminated mold type snail sludge dewatering machines are taken as an example.
如图 1所示的一种叠片模块式叠螺污泥脱水机，其主体内部主要包括外壳 3 由游动环 1、 固定环 2和螺旋推进器 15构成的脱水筒 14、进泥口 5、 出泥口 10 调速电机 9、 套管 13和滤液回收装置 1 1。 叠片模块 6内部依次排列若干个固定 环 2， 相邻固定环 2之间配置与固定环 2同心且可动的游动环 1， 底部设有滤液 回收装置 1 1， 螺旋推进器 15贯穿固定环 2和游动环 1内部， 所述的叠片模块 6 可拆卸， 并且可互相替换。  As shown in Fig. 1, a laminated modular type snail sludge dewatering machine mainly comprises a casing 3, a dewatering cylinder 14 composed of a swimming ring 1, a fixing ring 2 and a screw propeller 15, and a mud inlet 5 , the mud outlet 10 speed control motor 9, the casing 13 and the filtrate recovery device 1 1. A plurality of fixing rings 2 are arranged in sequence inside the lamination module 6, and a swimming ring 1 which is concentric and movable with the fixing ring 2 is disposed between the adjacent fixing rings 2, and a filtrate recovery device 1 is arranged at the bottom, and the auger 15 is inserted and fixed. Inside the ring 2 and the swimming ring 1, the lamination module 6 is detachable and replaceable with each other.
如图 2所示为叠片模块中固定环和游动环的连接示意图， 游动环 1和固定 环 2有若干个， 且固定环比游动环的内径大。 固定环 2之间的间隙设置为 0. 5〜 3mm, 游动环 1与固定环 2之间的间隙设置为 0. 05〜lmm， 这种间隙可根据污泥 处理对象的性质来调节设定。 固定环 2边缘设置有调整块 4， 其中每块调整块 4 用连接杆 12固定连接， 连接杆 12两端分别固定在叠片模块 6两端， 起到固定 固定环 2的作用， 使游动环 1活动时， 固定环始终保持固定。 Figure 2 shows the connection diagram of the fixing ring and the swimming ring in the lamination module, the swimming ring 1 and the fixing There are several rings 2, and the fixing ring is larger than the inner diameter of the swimming ring. The gap between the fixed ring 2 is set to 0. 5~ 3mm, the gap between the swimming ring 1 and the fixed ring 2 is set to 0. 05~lmm, and the gap can be adjusted according to the nature of the sludge treatment object. . The fixing ring 2 is provided with an adjusting block 4, wherein each adjusting block 4 is fixedly connected by a connecting rod 12, and two ends of the connecting rod 12 are respectively fixed at two ends of the lamination module 6, which functions as a fixed fixing ring 2 to make swimming When the ring 1 is active, the retaining ring is always fixed.
如图 3所示为螺旋轴和螺旋片的结构示意图， 其中螺旋轴 7和螺旋片 8焊 接在一起， 整体构成螺旋推进器 15。 沿出泥方向螺旋片 8之间的螺距 D逐渐变 小， 这样可以有效的提高污泥脱水率。  As shown in Fig. 3, a schematic view of the structure of the screw shaft and the spiral piece, in which the screw shaft 7 and the spiral piece 8 are welded together, integrally constitutes the auger 15. The pitch D between the spiral pieces 8 along the outflow direction gradually becomes smaller, which can effectively increase the sludge dewatering rate.
在工作过程中， 安装在出泥口 10侧面的调速电机 9启动， 首先带动螺旋推 进器 15旋转， 通过进泥口 5供给污泥， 污泥进入游动环 1和固定环 2之间的内 部空间， 由于游动环 1的内径比固定环 2的内径小， 旋转时污泥对游动环 1产 生压力推动游动环 1在固定环 2之间运动， 大部分水份在运动过程中通过游动 环 1与固定环 2之间的间隙流出至滤液回收装置 1 1。  During the working process, the speed regulating motor 9 installed on the side of the mud outlet 10 is started, firstly, the screw propeller 15 is rotated, and the sludge is supplied through the mud inlet 5, and the sludge enters between the swimming ring 1 and the fixed ring 2. The inner space, since the inner diameter of the swimming ring 1 is smaller than the inner diameter of the fixed ring 2, the sludge exerts pressure on the swimming ring 1 during rotation to push the swimming ring 1 to move between the fixed rings 2, most of the water is in motion The solution flows out to the filtrate recovery device 11 through the gap between the swimming ring 1 and the fixed ring 2.
如图 4所示为叠片模块 6之间的连接方式， 2组叠片模块 6下部由固定杆 17穿过焊接在滤液回收装置 1 1上的固定片 16连接， 通过螺母 18固定。 2组叠 片模块上部由固定杆 17连接， 通过螺母 18固定。 叠片模块 6拆卸的时候， 只 需将螺母 18卸下即可。  As shown in Fig. 4, the connection between the lamination modules 6 is carried out. The lower portions of the two lamination modules 6 are connected by a fixing rod 17 through a fixing piece 16 welded to the filtrate recovery device 1 and fixed by a nut 18. The upper part of the two sets of laminated modules is connected by a fixing rod 17, and is fixed by a nut 18. When the lamination module 6 is removed, only the nut 18 needs to be removed.
叠片模块 6 承受的压力沿着出泥方向逐渐增大， 因此靠近出泥口的叠片模 块 6 的叠片磨损程度最严重。 国内外现有的叠螺污泥脱水机， 其叠片为单片组 装式， 当靠近出泥口 10的叠片磨损到一定程度时， 叠螺污泥脱水机就不能充分 发挥它的能力， 影响处理效果， 拆卸组装繁琐。  The pressure applied by the lamination module 6 gradually increases along the direction of the mud out, so that the lamination of the lamination module 6 near the outflow port is most severely worn. The existing snail sludge dewatering machine at home and abroad has a laminated piece that is monolithic assembled. When the lamination close to the mud outlet 10 is worn to a certain extent, the snail sludge dewatering machine cannot fully exert its capability. Affecting the processing effect, the disassembly and assembly is cumbersome.
本发明将叠片设计成可拆卸的叠片模块形式， 当靠近排泥口的叠片模块磨 损到一定程度时， 将该叠片模块与其它任一个叠片模块互换， 由于其它叠片模 块所在位置承受的压力相对较低， 仍能保证叠螺污泥脱水机正常运行， 这样经 过反复替换， 可大大延长叠螺污泥脱水机的使用寿命。  The invention designs the lamination in the form of a detachable lamination module, and when the lamination module close to the mud discharge port wears to a certain extent, the lamination module is interchanged with any other lamination module, due to other lamination modules The pressure at the location is relatively low, and the normal operation of the snail sludge dewatering machine can still be ensured. Thus, after repeated replacement, the service life of the snail sludge dewatering machine can be greatly prolonged.
