The horizontal structure screw decanter is a new concept screw decanter newly developed in 2016. It arranges main driving motor and speed motor in horizontally intensive structure to minimize the occurrence of noise and vibration.
Strength of Horizontal Structure
*Lowers the center of load of the device by arranging main drive motor and back drive motor in horizontally intensive structure. It enables stable operation and also improves operation environment with less noise and vibration.
*Enhanced stability and durability through low frame height and improved solidity.
*Enhanced cake dehydration efficiency through extended torque value regulating range for scroll through tension dispersion of the driving part.
*Enhanced lifespan through minimized bending load between axes with left and right placement of reduction gear and pulley part.
Internal reduction gear box type
Internal reduction gear box type
Internal reduction gear box type decanter is a high-tech screw decanter developed in 2010. The external gear box, source of vibration in the existing screw decanter, is directly attached to the bowl and it prevents the vibration occurrence. It also prevents the malfunctioning in advance and has compact size.
*Development of internal gear box type decanter, vibration of cantilever structured external reduction gear.
*Weight lightening and improved durability of reduction gear through development of reduction gear for screw decanter.
*Enhanced dehydration performance through stable high-speed operation by the improved structural vibration.
Difference from the Existing Screw Decanter and Strength
*No reduction gear influencing the external vibration of the supporting bearing.
*Reduction gear is built in the bowl and it allows for the precise correction of dynamic balance and minimizes vibration during the high-speed rotation.
*Minimized vibration allows for increased speed of screw scanter and improves the performance of the decanter.
*The solution for vibration increase source drastically extends the device lifespan.
*Compact device with built-in reduction gear.
External Exchanging Multiple Bush
Extended lifespan and improved performance by changing the cake discharge caliber and exchanging the bush on site according to sludge characteristic
*Discharge caliber is changed by exchanging liner and bush within the same bush housing
Importance of Solid’s Discharge Bush
*Among the screw decanter parts, discharge bush has the most wear
*Uneven wear of discharge bush causes vibration of high-speed bowl and causes malfunctioning
*Constant operation in the excessive vibration state caused by the unavailable on-site bush exchange leads to increased number of malfunctioning and accidents.
