Product Introduction
Working Principle
LWL horizontal spiral discharge filter centrifuge is a model with low energy consumption, stable performance and good separation effect. The feeding, dehydration, washing, unloading and other processes in the separation process are completed continuously, with high production efficiency and automation. It is an advanced solid-liquid separation equipment.
The suspension enters the inner cavity of the spiral from the feed pipe, and enters the rotating drum through the spray port at the bottom of the cone end of the spiral. Under the action of the centrifugal force field, the liquid phase in the slurry passes through the screen laid on the rotating wall. are filtered out, and the solid particles are trapped in the drum; at the same time, the solid particles in 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 relative differential speed between the spiral and the drum. During this movement, due to the increase in rotation diameter, the centrifugal force increases rapidly, and the solid phase changes from a higher moisture content when it initially enters to a solid phase with the lowest moisture content when it is discharged from the drum, thereby realizing the solid-liquid phase. Automatic, continuous separation.
The centrifuge has a built-in washing tube, which can wash the filter cake while filtering it. Because it is a thin layer of filter cake washing, the washing effect is good and the consumption of washing liquid is low.
A steam pipe can be designed on the back of the drum to wash the crystallized material on the back of the drum at high temperature.
The spiral differential has three configurations: cycloidal differential, planetary differential and hydraulic differential, which can meet the separation of different materials.
Main performance and uses
LWL horizontal spiral discharge filter centrifuge is widely used in chemical, food, salt, mining, pharmaceutical and other industries. Because of its separation principle and structural characteristics, it is also highly specific to materials. It is mainly suitable for materials with larger particle sizes and no strict requirements for particle crushing. Material analysis and corresponding tests should be conducted during model selection to determine its applicability and separation performance.
Main Feature
The main parts such as drum and spiral are made of high-quality corrosion-resistant stainless steel, titanium alloy and other materials.
The drum angle can be selected from 10° or 20° according to process conditions.
Special filter metal mesh (thickness 0.4-0.5mm) or trapezoidal wire forming mesh (thickness 4.5-5mm) are optional.
Frequency conversion control, stepless speed regulation of drum speed.
Feeding, separation, washing, dehydration and pushing are completed continuously, with a large processing capacity.
Independent lubrication system, simple and reliable lubrication method, good cooling effect.
Safety protection: Configurable speed detection, over-vibration protection, motor overload and overheating protection.
For materials with high viscosity, a hydraulic differential can be used to ensure stable and reliable operation.
Drum Cone Angle
10°: This angle of drum is preferred when washing the filter cake is required.
20°: This standard angle has proven to be excellent for the separation of most materials. The solid phase slides from the small end to the large end with increasing centrifugal force, and there is almost no need for too much pushing force from the spiral.
