Brief description of centrifuge structure
The horizontal spiral discharge settling centrifuge consists of a drum combination, a spiral conveyor combination, transmission components and machine base, a casing, a feed pipe, an electrical control system, etc.
Transmission components: Both the main and auxiliary motors are regulated by frequency converters. According to the suspension
Adjust the drum speed and differential speed according to the changes in flow rate and suspended solid content to achieve the most ideal separation effect.
Drum combination: consisting of drum, drum left end cover, drum right end cover, overflow plate
Composed of tendons and other components.
The differential is an involute planetary gear differential, which consists of two stages of planetary gear transmission.
The rotary drum is a conical cylindrical body, connected at both ends by the left and right shafts of the rotary drum. It is coaxially installed on the left and right bearing seats of the rotary drum and fixed on the machine base. The screw conveyor is coaxially installed with the rotary drum through two sliding bearings; The output shaft of the differential is connected to the spline sleeve of the screw pusher through a spline shaft, and the housing is connected to the drum through a connecting flange. By adjusting the speed of the differential input shaft, different differential speeds can be obtained.
The machine base is the supporting component of the entire centrifuge, welded together from carbon steel parts.
The machine base is equipped with left and right bearing seats at both ends. The lower part of the machine base is equipped with a disc type rubber shock absorber distributed horizontally, which plays a role in vibration reduction.
Shell part: mainly responsible for collecting and exporting clarified liquid and sediment, while also playing a role
Security protection function.
Spiral conveyor combination: consisting of cylinder column section, material accelerator, partition, and spiral
The blade welding combination, as well as the hollow shaft, internal spline sleeve, and spline shaft. The spiral blades are uniformly welded onto the cylinder, and the surface of the blades is sprayed or embedded with hard alloy to increase the wear resistance and service life of the spiral; The conical section of the spiral cylinder is equipped with feeding holes, through which materials enter the drum.
Electrical control part: The electrical control cabinet adopts front and rear door opening forms, with built-in frequency conversion
Devices, PLC programmers, and other electrical components. The front door is equipped with buttons, indicator lights, voltage and current display meters, and a text display touch screen. The electronic control system has overload protection function, which uses the overload and overheating protection function of the frequency converter to automatically alarm or trip, promptly disconnect the motor power and feed valve power switch, and automatically stop and stop feeding.

Functional principle of centrifuge
Working principle (see structural schematic): The suspension continuously enters the inner cavity of the screw conveyor, and after being accelerated by the acceleration cone, flows out from the fabric port and into the working chamber of the rotary drum. Under the action of centrifugal force, the heavy phase particles (solid phase particles) that make up the suspension quickly deposit onto the inner wall of the rotary drum, forming a sediment layer, while the light phase particles (liquid phase particles) adhere to the inner surface of the heavy phase sediment layer, forming a clear liquid. A layer of interface is formed between the light and heavy phase particles. With the thickening of the heavy phase sediment layer

Do not use a frequency converter for speed regulation. Adjust the drum speed and differential speed according to the flow rate and solid content of the suspension to achieve the most ideal separation effect.
The electrical control system is advanced and reliable. The electrical control system adopts well-known domestic technology
The top of the spiral conveyor blade enters the sediment layer. Due to the high-speed rotation of the drum and the screw conveyor in the same direction, there is a certain differential speed, which causes the heavy phase sediment to continuously move towards the slag outlet at the small end of the drum under the action of the screw blades and be discharged out of the drum through the slag outlet. The light phase liquid flows through the spiral channel and exits the drum through the overflow port at the large end of the drum, and is discharged outside the machine through the discharge port, thus achieving continuous solid-liquid separation.
