Duwan Environmental's electric push rod type skimmer is priced to convert the linear lifting and lowering motion of the screw thread into a rotating motion of the overflow weir and drain pipe through a drive unit and a four-bar linkage mechanism, thereby skimming off the supernatant liquid. The floatation sludge discharge device forms a渣-free water outlet area above and below the weir mouth, as well as on both sides, with the floatation筒 floating on the water surface, which can automatically adjust the distance to the weir mouth.

Rotating Waste Water Separator in OperationFeatures
All underwater components of this equipment are made of stainless steel, ensuring a long lifespan and corrosion resistance.
2. The machine is driven by an electric actuator, featuring a compact structure, high thrust, easy installation, smooth operation, and reliable performance.
3. High effluent discharge, deep water level, stable and reliable operation, no disturbance to the liquid surface, low energy consumption of the entire machine, and long service life.
The principle of operation is as follows: The decanter is mounted on a bracket with support bearings and installed together in the pool. The electric push rod and reducer assembly is mounted on a bracket above the pool. When the motor operates, the electric push rod performs reciprocating motion, driving the decanter mechanism to rotate around the center of the lower bracket for oscillating movement. During the aeration and sedimentation stages, the decanter weir is above the water level. During decanting, the decanter weir descends through the control system below the water level for drainage. After the water level drops to a lower level and decanting is completed, the decanter quickly returns to its initial state. The water flow entering the decanter weir during the decanting process is in a laminar state, and the descent speed of the decanter maintains a stable water output. The float acts as a slag shield during the decanting process.
Rotary Decanter PriceThe strainer achieves automatic speed variation during operation, with a wide adjustment range. The equipment's operation is synchronized with the water level drop, which occurs at a constant speed. The operating speed during decanting can be selected according to different water qualities to achieve the desired rate of descent. Unlike slider lifting mechanisms, and even more so than pneumatic or hydraulic lifting devices, the rotary strainer converts the linear lifting and lowering motion of the screw thread into rotational motion of the overflow weir and drainage pipe through a drive mechanism and a four-bar linkage, to remove the supernatant liquid. The float sludge discharge device forms a slag-free discharge area above and below the weir mouth, as well as on both sides, with the floats floating on the water surface and automatically adjusting the distance to the weir mouth.
Rotary Rod Weir Dewatering System
Structural Form:
The unit is primarily composed of parts such as the electrical control box, electric push rod, main and branch drain pipes, weir slot components, buoy components, outlet components, stroke control, and base. The rotary decanter is connected between the submerged part and the actuator by the electric push rod. When drainage is needed, the central control system sends a signal, instructing the motor to drive the screw to rotate. The electric push rod pushes forward, and the collecting weir slot descends with the rotation of the horizontal pipe, initiating the decanting process. The clarified liquid is discharged through the drainage pipe. Upon completion of the decanting, the counter inside the push rod signals, causing the motor to reverse, pulling the collecting weir slot upwards back to the preset position, ready for the next cycle.
Performance Features:
1. Smart dewatering: the slower the dewatering speed as it approaches sludge, the better the water quality of the effluent.
2. Equipped with double limit switches and safety alarm devices, ensuring the equipment has a high level of safety.
3. Versatile Adaptability: By adjusting the internal parameters and the related parameters of the variable-frequency drive, the speed and operating range of the decanting machine can be correspondingly altered to meet different water quality and quantity requirements.
All travel control mechanisms are housed within a protective shield, safeguarded from the erosion of wind and rain.
5. Sealed rotating unions, offering smooth rotation and excellent sealing properties, allow for the replacement of seals without draining.
6. The electric actuator features a simple structure, making it easy to disassemble and maintain.
7. Configure manual, fully automatic, and supervisory control modes for easy operation and management.
All underwater components are made of stainless steel, requiring no maintenance, and are easily repaired for driving and control equipment.
The entire decanter has a sturdy frame that can withstand various pressures encountered during operation.
10. The decanter is designed with a split structure for easy transportation and installation.
11. Ingeniously designed, aesthetically pleasing, and space-saving installation.

Strainer Constant Flow Water and Electricity Control Solution Description:
1，Recommend installing one electromagnetic flow meter on the outlet main pipe of the decanter and an ultrasonic level gauge at the decanter location.1 unit, a set of water separator water outlet position sensors, and a control cabinet equipped with a variable-frequency inverter, a PLC, and a touch screen controller.
2，Control plan as follows: Set through programming, when...After a certain period of still water in the SBR pond, the decanter descends to the liquid level and begins the decanting process. The supernatant in the SBR pond enters the pipeline through the decanter's opening. An electromagnetic flow meter installed on the main outlet pipe provides an instantaneous flow signal. If the flow exceeds the set value, the distance between the decanting port and the liquid surface is reduced. This signal is derived from the position sensor of the decanter device and the ultrasonic level gauge, calculated by the PLC's built-in algorithm. If the flow is below the set value, the distance between the decanting port and the liquid surface is increased. This signal is also obtained from the position sensor of the decanter device and the ultrasonic level gauge, calculated by the PLC's built-in algorithm. As the liquid level continues to drop, the decanter descends with the liquid level, with the walking speed adjusted by the built-in variable-frequency inverter. Once the decanter reaches the lower limit position and the outlet flow drops to 0, the default drainage process is considered complete. The PLC controller then raises the decanter to the upper limit position at full frequency, awaiting the next decanting signal.
