           Volute Screw Press is a kind of spiral discharge settling centrifuge, it works continuously, which is pushes the slag to discharge port at the small end of the drum through the blades on the spiral pusher, and the liquid phase overflows through the overflow hole at the large end of the drum to achieve the purpose of continuous separation.

            The decanter is driven by two motors. The main motor drives the bowl and the housing of differential mechanism to rotate through belt, while the auxiliary motor drives through the belt pulley the input shaft of the differential mechanism to rotate, which, after speed change, drives the helical to rotate. In this way the bowl and helical rotate in the same direction but with certain differential speed. When the material to be processed (blended liquid consisting of solid phase and liquid phase) enters the inner cavity of the helical propeller through feeding pipe, after being accelerated by the two-way conical accelerator, it flows out of the material outlet, and flows into the bowl wall through inner cloth cylinder. The light, heavy and residue phases that make up the suspending liquid, under the action of different centrifugal force, the residue phase quickly subsides onto the inner wall of the bowl, and the heavy phase adheres close to the surface of the residue phase rather slowly, while the light phase adheres close to the surface of the heavy phase rather slowly, forming a dividing plane between the two phases. As the sedimentation of heavy phase increases, the top end of helical blade enters into the sedimentation layer of heavy phase. At this time the bowl and helical propeller are rotating in the same direction at high speed and with a certain difference in speed. This relative difference in rotation speed enables the helical to propel heavy phase particles to move toward the material outlet at the small end, whereas the light phase, through the helical passage, flows toward the liquid phase outlet at the large end, and flows out through the overflow plate with different R values. 

machine parts

 

feeding

The material is fed into the distribution chamber of the screw conveyor through the feed pipe, where the material is smoothly accelerated and enters the rotating drum through the outlet of the screw conveyor.

drum

Separate the materials in the cone and column drum. The drum rotates at a certain speed . The mixed liquid rotates under the drive of the drum, The denser solids in the liquid are deposited on the inner wall of the drum under the action of centrifugal force.

dual drive

Dual Motors drive and Dual Variable Frequency Converter drive to realize the function of soft starting and slow stop.

screw

The screw conveyor and the drum rotate asynchronously in the same direction, and the separated solid is pushed toward the cone section along the axial direction.

           this machine is horizontal spiral discharging settling centrifuge, the main machine has a column-cone bowl, spiral stoker,differential system, bearing seat, base, cover, main motor,vice motor, and electric control chamber. With the high speed rotating of bowl, form strong centrifugal force, making the sludge dehydrate continuously in 24 hours a day.

           The main motor through the triangle belt make the bowl rotating, through the planetary gear differential, make the vice motor and spiral differential speed different, realize sludge dewatering and pushing material function, That means differential rotating speed control and torque control. because containing solid rate of sludge may have wave motion, by differential speed control system is the guarantee for speed stability, achieve solid content in sludge is constant, the constant torque control make decanter load in a stable state, the separation effect and flocculation is the best state, so as to ensure the safe operation of the centrifuge.
           Volute Screw Press has good seal performance (guarantee without material leak in the process of operation), sludge dewatering work in full seal state, makes the environment clean.

           Volute Screw Press adopts the most advanced international special structural design, especially the spiral stoker, make the sludge concentration dehydration integration characteristics. It has better performance than ordinary centrifuge, more high capacity, better separation effect, save energy and manual work.

* Decanter centrifuges have a clean appearance and have little to no odor problems.
* Not only is the device easy to install and fast at starting up and shutting down but also only requires a small area for
operation compared to other competitive processes.
* The decanter centrifuge is versatile as different lengths of the cylindrical bowl section and the cone angle can be selected for different applications. Also, the system can be pre-programmed with various design curves to predict the sludge type, while some competitive processes, such as a belt filter press, cannot change the belt type to operate for different sludge types. Its versatility allows the machine to have various functions such as operating for thickening or dewatering.

* The machine can operate with a higher throughput capacity than smaller machines. This also reduces the number of units required.
* The device is simple to optimize and operate as it has few major variables and reliable feedback information.
* The decanter centrifuge has reduced labor costs compared to other processes, as it requires low continuous maintenance and operator attention.
* Compared to some competitive process such as the belt filter process, the decanter centrifuge has more process flexibility and higher levels of performance.
