Operation Management of Decanter Centrifuge

When the decanter centrifuge is in operation, its high-speed rotating drum will generate strong centrifugal force to throw solid particles with a higher density than the liquid phase on the inner wall of the drum, forming a solid layer (because of the ring shape, called solid Ring layer); Because of the low density and low centrifugal force, the moisture can only form a liquid layer inside the solid ring layer, which is called the liquid ring layer.

Because the rotation speed of the screw and the drum are different, there is a relative movement between the two (that is, the difference in rotation speed). The relative movement of the screw and the drum is used to slowly push the sludge in the solid ring layer to the cone end of the drum and pass through the drying zone. After that, the outlets distributed around the circumference of the drum are discharged one after another, and the liquid in the liquid ring layer is discharged from the weir mouth to the outside of the drum by gravity to form a separated liquid.

1. Operation management of decanter centrifuge

Because the decanter centrifuge system is a blast furnace gas washing water sludge treatment system, the quality of the recovered water changes greatly, the sludge particles cause serious wear on the equipment, and there are many uncertain factors in external influences. In addition, the system has many types of treatment equipment and treatment Links are intertwined and require higher requirements for operating personnel. Therefore, to ensure the normal operation of each link and give full play to the effects of various facilities and equipment, it is necessary to strengthen daily operation management and have a set of management measures to ensure it.

2. The effect of decanter centrifuge

The decanter centrifuge uses the centrifugal sedimentation principle to separate the drilling suspension, which is pushed to the slag discharge port at the small end of the drum through the blades on the screw pusher, and the liquid phase overflows through the overflow hole at the large end of the drum. Such continuous circulation, in order to achieve the purpose of successive separation.

3. Liquid separation of decanter centrifuge

　　1: Use involute planetary gear differential, with large transmission ratio and high precision.

　　2: The whole machine is equipped with two-layer overload protection device for mechanical and electrical appliances, which is safe to use.

　　3: Power frequency speed-regulating main motor is equipped with hydraulic coupling, and the motor runs smoothly.

　　4: The parts that touch the material are made of high-quality stainless steel, which has strong corrosion resistance.

　　5: The whole machine adopts an integral frame structure, which is safe and convenient for hoisting and has a small area.

       6: The explosion-proof grade of power frequency and frequency conversion electrical appliances, and the control box has good sealing performance.

Problems to be paid attention to when using electric centrifuge

Nowadays, electric centrifuges are commonly used in laboratories. Because of their fast rolling speed, pay attention to safety. In particular, avoid moving the centrifuge while it is working due to imbalance or aging of the test tube pad during the operation of the centrifuge. When the test bench fell off, or because the lid was not covered, the centrifuge tube broke due to vibration, and the glass fragments spun out, causing an accident. Therefore, when using the centrifuge, it is necessary to pay attention to the following operations:

　　 (1) The centrifuge shall be placed at horizongtal leval platform.

　　 (2) If the electric centrifuge is noisy or the body oscillates, the power supply should be blocked immediately, and the fault should be eliminated immediately.

　　 (3) Centrifuge tubes must be symmetrically placed in the casing to avoid vibration of the machine body. If there is only one sample tube, the other should be replaced with water of equal mass.

　　 (4) When starting the centrifuge, cover the top cover of the centrifuge before starting slowly.

　　 (5) After the separation is over, first close the centrifuge. After the centrifuge stops rolling, open the centrifuge cover and take out the sample. Do not use external force to force the suspension of the movement.

　　 (6) The centrifugation time is usually 1 to 2 minutes, during which the experimenter is not allowed to leave to do other things.

　　Notes for the use of tabletop low-speed large-capacity electric centrifuge:

　　 1. All kinds of liquids or other sundries are prohibited from entering the centrifuge working chamber. Otherwise, the host will be damaged.

　　 2. The case of the instrument should be properly grounded to avoid accidents caused by the influence of moisture.

　　3. Please do not open the upper cover at will when the centrifuge head is running at high speed.

　　 4. When the setting is wrong, it will actively alarm to remind you to reset.

 If you find that the centrifuge head is eccentric when using the centrifuge, please check and repair it. First remove the rotor and then open the bottom cover to check if the motor prop is off. Then adjust it.
