LLW horizontal spiral discharge filtration centrifuge

Working principle of horizontal spiral filtration centrifuge:

The suspension enters the spiral cavity from the feed pipe and enters the rotary drum through the spray port near the bottom of the cone end of the spiral small head. Under the action of centrifugal force field, the liquid phase in the slurry is separated by the sieve set on the rotating wall, while the solid particles are trapped in the rotary drum; At the same time, the solid particles inside the drum move from the small end of the drum to the large end of the drum under the action of centrifugal force and the differential speed between the spiral and the drum. During this movement, due to the increase in the rotating diameter, the centrifugal force increases rapidly, and the solid phase enters the drum from a high moisture content solid phase at the beginning to a low moisture content solid phase when it is discharged from the drum, thus achieving automatic and continuous separation of the solid-liquid phase.

The LLW horizontal spiral discharge filter centrifuge is a model with low energy consumption, stable performance, and good separation effect. Widely used in industries such as chemical, food, salt, mining, and pharmaceuticals (we have successful application experience in separating dozens of materials, and can communicate with our technical personnel when selecting for more detailed information). The continuous completion of processes such as feeding, dehydration, washing, and unloading during the separation process results in high production efficiency and automation, making it an advanced separation equipment.

Due to its separation principle and structural characteristics, it has strong specificity for materials. When selecting, material analysis and corresponding tests should be conducted to determine its applicability and separation performance.

Main uses of horizontal spiral filtration centrifuge:

　Used for adipic acid, saltpeter, arsenic, AH salt, ammonium persulfate, gypsum, silver nitrate, ammonium phosphate, ammonium sulfate, ammonium thiosulfate, ion exchange resin, sodium chloride, anthracene, sodium chlorate, aspirin, sodium formate, manganese sulfate, borax, methyl cellulose, sodium metaborate, calcium formate, sodium nitrate, sodium perborate, sodium phosphate, citric acid, sodium sulfate, polystyrene, polystyrene alcohol, baking soda, copper sulfate, potassium carbonate (potassium carbonate), tartaric acid, crystalline soda, potassium vanadium, trisodium phosphate, potassium bicarbonate, zinc sulfate, pentaerythritol, plastic pellets, glacial acetic acid, potassium chloride, dipotassium pentasulfide, potassium phosphate, potassium sulfate

Main features of horizontal spiral filtration centrifuge:

1. The main components such as the drum and spiral are made of corrosion-resistant stainless steel, titanium alloy, and other materials. The cone angle of the drum is 10 ° or 20 °.

2. The specially designed inverted cone ring at the front end of the conical drum enables the drum to achieve dual dewatering effects of filtration and settling.

3. Continuous feeding, separation, cleaning, dehydration, solid discharge, fully continuous.

4. Specially customized filter metal mesh, with a thickness of up to 1.5mm, has a longer service life.

5. Large processing capacity and good cleaning effect.

6. Variable frequency control, infinitely adjustable drum speed.

7. Spiral differential speed is adjustable.

8. Independent lubrication station, simple and reliable lubrication method, good cooling effect.

9. Safety protection: It can be configured with speed detection, over vibration protection, motor overload and overheating protection, and spiral zero differential protection.

Characteristics of hydraulic differential:

1. Single and double row inner curved radial plunger low-speed high torque hydraulic differential, with a large output torque (2-3 times greater than mechanical type);

2. Differential feedback control with overload alarm output terminal, maximum pressure alarm, shutdown;

3. Equipped with pressure protection device;

4. Differential speed of 1-20 r/min, infinitely adjustable during operation, convenient;

5. When overload and blockage occur during the material pushing process, it has the functions of differential automatic acceleration and power automatic compensation. The differential feedback compensation range is large and there will be no blockage;

6. Maintain the original set initial differential pushing torque without changing the differential speed (easy to achieve small differential operation);

7. Strong adaptability to material changes (with differential automatic feedback, functional compensation, and large pushing torque);

8. Hydraulic slag discharge can be started when the drum stops, without the need for disassembly and cleaning, making troubleshooting convenient;

9. Can achieve automatic control
