Product Details

Guangzhou sells second-hand LW720 horizontal screw centrifuge

centrifugeIt is widely used in many fields of the national economy, such as chemical and pharmaceutical industries, and is still the main equipment for solid-liquid separation in current production processes of chemical intermediates, pharmaceutical raw materials, etc. Due to the different applications, processes, and physical and chemical properties of the media used in these industries, there are also different requirements for centrifuges, such as material requirements, structural requirements, anti-corrosion requirements, explosion-proof requirements, etc.

Guangzhou sells second-hand LW720 horizontal screw centrifuge

Second hand solid-liquid separation horizontal screw centrifuge Gongshan price fluctuation vacuum sterilizer, single effect concentration evaporator, horizontal sterilization pot, layering pot, ingredient pot, ball concentrator, cutting machine, vacuum drying oven, etc. So the equipment was manufactured in 2015. Now *. 13 second-hand refrigerated vacuum dryers, including a 5-square-meter refrigerated vacuum dryer, a 10 square meter refrigerated vacuum dryer, a 15 square meter refrigerated vacuum dryer, a refrigerated dryer, and a low-temperature refrigerated vacuum dryer, manufactured by Shanghai Dongfulong and Shanghai Huadong Company respectively. Pure steam generator, equipment, basically useless, second-hand refrigerated dryer, second-hand freeze dryer. Triple effect concentration evaporator, concentration and extraction equipment, second-hand vacuum freeze dryer, double cone vacuum dryer, V-type mixer, multi-directional motion mixer, high-efficiency coating machine, multi effect distilled water machine, tubular distilled water machine, double effect evaporator, multi-directional evaporator, falling film evaporator, single effect evaporator, stainless steel condenser, low-priced processing equipment for the entire site

(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.
