Sludge dewatering machine It is a kind of equipment used to remove the water in the sludge efficiently. Its working principle is to separate the water in the sludge by mechanical pressing or centrifugal separation, so as to achieve the dewatering effect of the sludge. The following is an analysis of two common working principles of the sludge dehydrator:
1. Mechanical pressing principle:
The working principle of mechanical pressing of sludge dewatering machine is similar to that of filter press. Through the action of certain pressure and mechanical force, the water in sludge is squeezed out to achieve dewatering effect. Usually, the sludge is transported to the filter screen or the inside of the drum. The water in the sludge is squeezed out through the rotation or compaction of the drum or the filter screen by the press, and the sludge gradually becomes drier. After pressing treatment, the water in the sludge is effectively removed to achieve dehydration effect.
2. Centrifugal separation principle:
Another common working principle of sludge dehydrator is centrifugal separation, which uses the centrifugal force generated by high-speed rotation of equipment to separate solid particles and water in sludge. stay Centrifugal separator Internally, after the sludge mixture is input, due to the density difference of different substances, the solid particles and water are separated, the solid particles settle to the bottom of the machine under the action of centrifugal force, and the water is discharged outside the machine to achieve the sludge dewatering effect.
In general, the sludge dewatering machine can efficiently remove the water in the sludge through the working principle of mechanical pressing or centrifugal separation, improve the drying effect of sludge, reduce the water content, and facilitate the subsequent treatment of sludge and resource recovery. Different types of sludge dehydrators use different working principles. Users can select suitable equipment according to actual needs and sludge characteristics to achieve the best dewatering effect and economic benefits.
During the dewatering process, the sludge dewatering machine will also use dewatering devices such as filter cloth, filter screen or centrifugal basket to increase the dewatering area, speed up the dewatering speed and improve the dewatering efficiency. These devices can help to better separate the water in the sludge, reduce the water content, and make the sludge more dry.
In addition, for the sludge dehydrator based on the mechanical pressing principle, the common pressing methods include roller pressing, plate and frame pressing, etc. Drum pressing is to place the sludge in the rotating drum, and water is squeezed out through the pressure difference between the inside and outside of the drum; Plate and frame pressing is to place the sludge between the plates and frames, and then apply a certain pressure to extrude the water.
The centrifugal part of the sludge dehydrator with centrifugal separation principle is usually composed of a rotating centrifugal basket or a centrifugal drum. When the machine rotates at high speed, the centrifugal force makes the solid particles in the sludge fly away, and the water is squeezed out of the machine, making Solid-liquid separation Achieve the expected effect.
In general, the sludge dehydrator uses the working principle of mechanical pressing or centrifugal separation to effectively remove the moisture in the sludge, so as to achieve the effect of dehydration and drying. When selecting a suitable sludge dehydrator, factors such as sludge characteristics, treatment capacity, dewatering efficiency and equipment stability should be comprehensively considered to achieve high efficiency, economy and environmental protection Sludge treatment And resource utilization objectives.
