　　Fully automatic centrifugal dewatering equipment - horizontal screw centrifuge

　　The fully automatic centrifugal dewatering equipment, also known as the horizontal spiral centrifuge, is an efficient centrifugal separation and settling device that operates continuously for 24 hours and discharges materials horizontally. Horizontal spiral centrifuge can generally be divided into horizontal spiral filtration centrifuge and horizontal spiral settling centrifuge. This device has a small footprint, can operate 24/7, is fully automatic without the need for manual supervision, and does not require maintenance costs in the future.

　　Chinese name: Flat screw dewatering machine

　　English name: Horizontal screw centrifuge

　　Abbreviation: Horizontal screw centrifuge

　　Types: Filtration centrifuge and sedimentation centrifuge

　　The working principle of the centrifugal dewatering equipment, the horizontal screw centrifuge, is as follows:

　　It mainly consists of a high-speed drum, a screw conveyor with a hollow shaft that rotates in the same direction as the drum and has a slightly lower speed than the drum, and a differential. When the suspension to be separated is sent into the drum by the hollow shaft, it is immediately thrown into the drum cavity under the centrifugal force generated by high-speed rotation. The high-speed rotating drum generates strong centrifugal force, which throws solid particles with higher density than the liquid phase onto the inner wall of the drum, forming a solid layer (called a solid ring layer due to its ring shape); Due to its low density and centrifugal force, water can only form a liquid layer inside the solid ring layer, known as the liquid ring layer. Due to the different rotational speeds of the spiral and the drum, there is a relative motion (i.e. speed difference) between the two. The relative motion between the spiral and the drum is used to slowly push the sludge in the solid ring layer to the cone end of the drum, and after passing through the drying zone, it is continuously discharged through the outlet distributed around the circumference of the drum; The liquid in the liquid ring layer is continuously 'overflowed' by gravity from the weir to the outside of the drum, forming a separated liquid.

　　The main dehydration process can be summarized as follows:

　　The suspension enters the drum from the feed pipe, and the solid particles are accelerated and settled on the inner wall of the drum under the action of centrifugal force. The settled particles are pushed by the blades of the screw conveyor and are discharged from the settling zone (straight section) through the drying zone (cone section) to the solid phase outlet; The clarified liquid phase overflowed from the overflow hole. Thus achieving automatic and continuous separation of solid and liquid phases.

　　The structure and performance advantages of the horizontal screw centrifuge in centrifugal dehydration equipment:

　　1. Good adaptability: Various special requirements of materials and processes for centrifuges have been fully considered in the process, and optimization design has been implemented for the main components in terms of specificity and adjustability. As long as the user explains the installation and use location, physical and chemical properties of material handling, process requirements, etc. before purchasing the machine, we will provide the user with the applicable model.

　　2. High degree of automation: The feeding, separation, unloading, and other processes of the centrifuge during operation are continuously and automatically carried out at high speed. Using programmable controllers to achieve automatic control of centrifugal separation and centrifugal washing processes.

　　3. Good operational stability: The differential used in the centrifuge is a cycloidal or planetary differential, which has the characteristics of high torque and wide adjustment range.

　　4. Strong craftsmanship: The centrifuge adopts a dual motor dual frequency conversion energy feedback differential speed system control, which flexibly and infinitely adjusts the differential speed and adjusts it at any time according to the changes in the material. Truly energy-efficient products.

　　5. Good operating environment: The separation of materials by the centrifuge is carried out under completely sealed conditions, ensuring a clean and pollution-free operating site and maintaining a clean and hygienic production environment, achieving civilized production.

　　6. The safety protection device is complete and reliable: the centrifuge is equipped with multiple protections such as torque protection and power control, which can effectively eliminate or reduce the damage caused by sudden failures to the machine.

　　7. Beautiful appearance: The base of this machine is made of carbon steel welded together, and the surface is treated with special technology to be smooth and flat. Lightweight, generous, and aesthetically pleasing, giving people a sense of overall beauty.
