Overview

A centrifuge is a mechanical device that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids with different densities in emulsions (such as separating cream from milk); It can also be used to remove liquids from wet solids, such as using a washing machine to spin dry and wet clothes; The special high-speed tube separator can also separate gas mixtures of different densities; Where to recycle second-hand Flavia Alfa Laval centrifuges by utilizing the characteristic of different settling velocities of solid particles with different densities or particle sizes in liquids

Where to recycle second-hand Fulewei Alfa Laval centrifuges

A centrifuge is a mechanical device that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids with different densities in emulsions (such as separating cream from milk); It can also be used to remove liquids from wet solids, such as using a washing machine to spin dry and wet clothes; The special high-speed tube separator can also separate gas mixtures of different densities; By taking advantage of the different settling velocities of solid particles with different densities or particle sizes in liquids, some settling centrifuges can also classify solid particles according to density or particle size.

(1) Sludge feeding system: This system consists of a sludge cutting machine, sludge feeding pump, electromagnetic flow meter, manual valve, etc.
(2) The flocculant dispensing system: This system consists of a booster pump, a jet pump, a dispensing tank, a storage tank, a mixing ball, a dosing pump, a rotor flowmeter, and pipelines.
(3) Separation host: Large aspect ratio horizontal screw centrifuge (dehydration type, concentration and clarification type)
I. Differential configuration: Mechanical differential: Differential is adjusted by replacing the pulleys, with an adjustment range of 5-25 r/min
II. Mechanical differential with ten double frequency converters: The left speed is infinitely adjustable with a frequency converter, with an adjustment range of 5-25r/min and an alarm.
(4) Cement cake conveying system:
I. Shaftless Spiral Conveyor: The material of the conveyor is stainless steel; Inner cushion ABS, spiral shaftless type. Conveyor length according to user requirements
Fixed, single conveyor length ≤ 10m, inclination ≤ 25 °
II. Alternatively, a sludge transfer pump can be used: an imported sludge transfer pump can directly transport the separated sludge to the designated location.
(5) Electrical control box:
The electrical control box is equipped with imported frequency converters and related electrical components for separating the main engine speed regulation.
II. Function: Rotary drum variable frequency speed regulation, agitator, cutting machine, sludge pump, screw conveyor start stop switch, current, voltage, etc
Display of traffic and accumulated running time. This function is used to control the operation of the entire dehydration system.

2、 Working principle
The sludge to be treated is connected to the input end of the sludge feeding system through a pipeline. The long fiber impurities in it are cut and crushed by a sludge cutting machine, and then metered by a flow meter through a feed pump (single screw pump) and input into the sludge dewatering machine (horizontal screw centrifuge).
The flocculant (powder or liquid) is diluted and fully dissolved in the mixing tank according to the proportion, and then enters the storage tank. The mountain dosing pump controls the flow rate determined by the dehydration process requirements. After dilution with water at a concentration of 0.08-0.12%, it enters the dewatering machine and mixes with the sludge to be treated. The flocculant solidifies into a dense state. After the sludge is dehydrated by the dewatering host, the clarified sewage is discharged through the pipeline of the mountain clarification liquid, and the dehydrated sludge is discharged from the discharge outlet of the host and then transferred to the site or directly loaded onto the truck for external transportation by a flexible shaftless sludge conveyor (or sludge conveying pump). The continuous input of sludge to be treated, the continuous discharge and transportation of clarified liquid and dehydrated sludge is a fully automatic treatment process. The dosing, feeding, sludge transportation, and operation of the main unit of the grid device are all detected and controlled by a fully automatic PLC electro-hydraulic control box, making the device a fully automatic complete set of operating units.
