Screw Sedimentation Centrifuge Operation Instructions: 1. Before use, open the machine cover, wipe off any accumulated water, and let it air dry naturally. Gently lower or raise the direction of rotation before and after centrifugation to avoid collision with the shaft and rotating parts. 2. Secure the machine as much as possible to prevent movement, tighten the fixing screws, and check for any cracks or corrosion on the body. 3. Clean up broken glass or other debris during operation to prevent damage to the centrifuge. 4. Ensure stable voltage during use to prevent burning out the internal circuitry due to voltage fluctuations. Connect the power supply in unstable voltage conditions to avoid damaging the centrifuge. If the centrifuge is found to be rusted, replace it immediately. Regularly apply specialized lubricating oil to the rotor, cabin, and sleeve to prevent corrosion. The oil should be applied to the shaft, ear of the hanger, and other components. The centrifuge should be used regularly to remove dust from the back. 7. Some centrifuges use a vacuum system, which is part of the vacuum process but has a low vacuum degree. Its purpose is to reduce the frictional heat of the rotor in the air, reduce the rotational noise of the rotor, and also help reduce the motor load. Used Horizontal Screw Centrifuge for Sale: Working Principle: The horizontal screw centrifuge is a spiral discharge sedimentation centrifuge. It mainly consists of a high-speed drum, a spiral conveyor with a hollow shaft rotating in the same direction as the drum but at a slightly lower speed, and a differential. When the suspension liquid to be separated is sent into the drum through the hollow shaft, it is immediately thrown into the drum cavity due to the centrifugal force generated by high-speed rotation. The rotating drum produces a strong centrifugal force, which throws the solid particles heavier than the liquid phase onto the inner wall of the drum, forming a solid layer (due to its annular shape, it is called the solid ring layer). Since the water has a smaller density and a smaller centrifugal force, it can only form a liquid layer inside the solid ring layer, called the liquid ring layer. Due to the different speeds of the spiral and the drum, there is relative motion between them (i.e., a speed difference), which slowly pushes the sludge in the solid ring layer to the conical end of the drum using the relative motion of the spiral and the drum. After passing through the drying zone, the sludge is continuously discharged through the outlet distributed around the drum circumference. The liquid in the liquid ring layer is continuously overflowed from the overflow port at the large end of the drum and discharged through the outlet. Professional Sale of Used Horizontal Screw Centrifuge: Operation Management: Due to the high variability of the recovered water quality in the blast furnace gas desulfurization sludge treatment system, severe wear on the equipment by the sludge particles, many uncertain factors from the outside world, and the diversity of the processing equipment and the interlaced processing stages, high requirements are placed on the operation personnel. To ensure the normal operation of each stage and to give full play to the role of each facility and equipment, it is necessary to strengthen daily operation management and have a set of management measures to ensure it. Function: The horizontal screw centrifuge separates drilling suspension liquids using the centrifugal sedimentation principle. The sludge is pushed to the discharge port at the small end of the drum by the blades on the spiral pusher, while the liquid phase is overflowed through the overflow port at the large end of the drum. This cycle continues to achieve continuous separation. Liquid Separation: 1. Uses involute planetary gear differential, with a large transmission ratio and high precision. 2. The whole machine is equipped with mechanical and electrical overload protection devices, ensuring safety. 3. The main motor with frequency conversion is equipped with a hydraulic coupler, ensuring smooth motor operation. 4. The material in contact with the material is made of stainless steel, with strong corrosion resistance. 5. The whole machine adopts an integral frame structure, making it safe and convenient for lifting and occupying less space. 6. The frequency and variable frequency electrical explosion-proof grade is ExdⅡBT4, and the control box has good sealing performance. The working principle of the centrifuge is that the drum and the spiral rotate at a certain speed difference in the same direction at high speed. The material is continuously introduced into the conveying spiral inner cylinder through the feeding pipe, accelerated, and then enters the drum. Under the action of the centrifugal force field, the heavier solid phase matter settles on the drum wall to form a sediment layer. The conveying spiral continuously pushes the deposited solid phase matter to the conical end of the drum, and discharges it out of the machine through the discharge port. The lighter liquid phase matter forms an inner liquid ring and is continuously overflowed from the overflow port at the large end of the drum and discharged through the outlet. This machine can continuously feed, separate, wash, and discharge at full speed. It has the characteristics of compact structure, continuous operation, stable operation, strong adaptability, large production capacity, and convenient maintenance. It is suitable for separating suspensions containing solid particles with a particle size greater than 0.005mm and a concentration range of 2-40%. It is widely used in chemical, light industry, food, environmental protection, and other industries. Choosing the right horizontal screw centrifuge can not only solve production problems and improve work efficiency but also save production costs and reduce business risks. The main factors affecting the selection are as follows: 1. Centrifuge speed: Generally, the horizontal screw centrifuge should be above 3000 rpm. The higher the speed, the higher the separation factor of the centrifuge, and the better the separation effect. 2. Centrifuge material: Different materials have different wear resistance, corrosion resistance, and other physical and chemical properties. Foreign horizontal screw centrifuges generally use low material grade 316L or duplex stainless steel, and abrasive components must be selected from ceramic composite materials. 3. Centrifuge differential control: Different differential gears have different control accuracy, and there are significant differences in lifespan and maintenance costs. The higher the differential accuracy, the better the adaptability to the material, so it is advisable to choose equipment with high differential accuracy. 4. Length-to-diameter ratio: The longer the length-to-diameter ratio of the horizontal screw centrifuge, the greater its processing capacity and the smaller its moisture content. 5. Control system: Whether it is automated programming control, domestic and foreign equipment manufacturers have basically realized the full automation control of this equipment. 6. Installation power: It affects energy consumption control. Generally, domestic equipment has higher energy consumption than foreign equipment. 7. Processing and manufacturing technology: The horizontal screw centrifuge belongs to a high-precision processing separation equipment. Products produced by enterprises without precision processing capabilities have a high repair rate and limited processing capacity.
