the horizontal decanter centrifuge to be used of increasing sedimentation volume in a cylindrical vessel

摘要

The present invention relates to an outer bowl, an inner screw and an associated support fixture of a horizontal centrifuge. It is to reduce the diameter of the main body of the inner screw and the diameter of the outer bowl compared to the conventional horizontal centrifuge. As the shaft diameter of the inner screw is reduced, the position of the separation liquid discharge port is also moved to a lower position toward the shaft center. Such a change soon provides a cause for increasing the content. Therefore, the volume of the centrifugal sedimentation portion is increased due to the change of the position of the separation liquid discharge port based on the reduction of the screw shaft diameter, thereby increasing the sludge treatment capacity. ; In addition, the reduction of the shaft diameter also reduces the diameter of the bearing block to be fixedly supported. This reduces the volume of the support portion inserted into the bowl as shown in the figure. Accordingly, the reduction of the volume of the inner screw and related parts in the centrifugal bowl provides the effect of expanding the processing capacity because the volume can be extended by the amount of the reduction. ; By thus reducing the volume of the rotating body (ball, screw) and its support (bearing block), the volume was increased without the weakness of reducing the effective volume in which the fluid is received. This reduces the size of the sediment separator external external bowl and screw, but rather increases its effective effective capacity. ; Accordingly, the weight and torque force can be reduced according to the volume reduction of the cyclic object, which can reduce the power cost, reduce the production cost, improve the effect of reducing the manufacturing capacity, and reduce the manufacturing, transportation, and installation cost. Provide the cause. In addition, the frictional resistance of the bearing support (bearing block) according to the reduction of the physical weight of the centrifugal body is significantly reduced, thereby extending the life of the device. ; However, in improving this, the structure has been improved without any problems such as deterioration of mechanical performance and poor processing efficiency. ; Horizontal Centrifuge, External Bowl, Internal Screw, Bearing Block
