Description: Original title: Principle and structure of disc separator According to the function, it can be divided into two types: solid-liquid separation type and solid-liquid-liquid separation type. The solid-liquid disc separator is one of the series of disc separators, which is an advanced equipment with high efficiency, large output and high automation. Disc separators are only suitable for the separation of suspensions with low solid content and mutually insoluble liquids with small specific gravity difference. The working principle of the disc separator is based on the centrifugal field force generated by the high-speed rotation of the equipment. In the centrifugal field force, the solids with heavy specific gravity are deposited on the drum wall according to the different specific gravity of the materials. The solids and a small amount of liquid are discharged out of the machine through the control of PLC. The light liquid phase flows to the upper part along the outer conical surface of the disc toward the axis, passes through a light liquid centripetal pump, and is discharged out of the machine through a light liquid port. O as to achieve the purpose of separating the solid and the light liquid. Solid, liquid, liquid three disc separator is specially designed and produced for the same material with two different specific gravity of the liquid. The motor drives the main axis of the rotary drum to rotate at a high speed through the friction clutch helical gear. The feed liquid flows from the uppercentral feed pipe to the bottom of the rotary drum and tends to the rotary wall through the shunt hole under the disc. Under the action of the centrifugal force field, the solid phase heavier than the liquid sinks to the inner wall of the rotary bowl to form sediment. The light liquid flows to the upper part along the outer conical surface of the conical disc toward the axis and is discharged through the light liquid centripetal pump. The heavy liquid tends to the wall of the drum along the inner conical surface of the disc, and then flows upward through the heavy liquid centripetal pump and is discharged from the heavy liquid outlet, thereby completing the separation of the heavy liquid and the light liquid. I. Product Features 1. After accurate dynamic balance calibration, the drum runs smoothly, with small vibration and low noise. 2. All parts in contact with materials are made of stainless steel, which can effectively reduce the corrosion of separated materials and meet the requirements of food hygiene. 3. Equipped with a static heavy and light phase discharge centripetal pump. The separated light and heavy phase materials are respectively output by a light and heavy phase centripetal pump at the top of the rotary drum, wherein the light phase enters the next process. 4. The hydraulic coupling and a pair of spiral speed-increasing gears are used for power transmission, and the liquid is used to transmit the power, which not only increases the speed smoothly, but also provides overload protection. 5. Equipped with automatic control cabinet. It is composed of an industrial computer and an automatic overload protector. It has a high degree of automation, strong adaptability to process adjustment, convenient adjustment, and can greatly reduce the operation intensity of workers. Expand the full text II. Overview of main structures Dish separator is mainly composed of inlet and outlet devices, drum, cover, vertical shaft, horizontal shaft, base, motor and automatic control box. 1. Inlet and outlet devices The inlet and outlet device can not only visually see the liquid conditions before and after separation, but also adjust the separation effect by adjusting the flow control valve on the device. A sampling device is arranged on the upper part of the machine cover, and the best fruit division is achieved by sampling and testing. 2. Drum part The drum part is the heart part of the machine, which completes the material separation process and rotates at a high speed. It is connected to the vertical shaft through a high-precision taper fit to obtain power. The parts of the rotary drum shall have the factory number and shall not be interchanged. The disc group is arranged on the distributor according to the number sequence, and the disc pressing cover and the rotary drum cover are pressed on the rotary drum body by the disc pressing cover. Note that the phase marks of each part must be aligned. O as to ensure that the balance before leaving the factory is not damaged. Otherwise, do not start the equipment. 3. Vertical shaft part A vertical shaft is a component which transmit power and is provide with a speed increasing gear (small helical gear) and rotates at a high speed. Because the axial direction and the radial direction are elastically supported, the rotary drum and the centripetal pump, the rotary drum and the water inlet cover can obtain the optimal working position by adjusting the lifting height of the vertical shaft. The height of the vertical shaft has been adjusted and locked before leaving the factory. Without the guidance of our professionals, it is not allowed to adjust the height of the vertical shaft at will. The bearings on the vertical shaft are all high precision imported bearings, hemp extraction centrifuge ,nutsche filter dryer, which are not allowed to be replaced by ordinary bearings. 4. Horizontal axis part The horizontal shaft is the main component that transmits the power of the motor to the vertical shaft and the drum. It is composed of motor, coupling, hydraulic coupling, transmission shaft, large spiral gear, brake wheel and other parts. Its structure is compact and its operation is stable. The hydraulic coupling is used for transmission and plays the role of overload protection at the same time. The large helical gear continuously splashes lubricating oil to the transmission bearings during operation, so that all bearings are well lubricated. The brake device is used to quickly pass through the resonance speed area of the machine when the machine is stopped, so as to reduce the stopping time and avoid the damage of the machine caused by resonance. 5. Machine cover The machine cover is a component connecting the machine body and the inlet and outlet devices, and is composed of an upper cover, a lower cover, a water inlet cover and other components. The adjusting shim on the top of the upper cover is used to adjust the height of the centripetal pump, to ensure that the centripetal pump is in the best position, and to ensure that the high-speed rotating drum parts will not rub against and damage the parts. The height has been strictly adjusted correctly before leaving the factory, and the general user does not need to change it. Unless it may be adjusted when the vertical shaft is overhauled. The lower cover is mainly used as a slag discharge channel, and is designed with a through hole specially used for assembling and disassembling the small piston and the valve body, which is used for repairing the sealing condition of the small piston and the valve body and replacing the sealing ring. There is no need to disassemble the whole drum. Note that the surface of the parts must be cleaned during each assembly and disassembly, and the lubricating oil must be applied evenly to prevent damage to the sealing ring. 6. Operate the water pipeline The water inlet cover is a stainless steel welded shell used to distribute the operating water. Through the action of the three solenoid valves connected to it (the solenoid valves are controlled by PLC programmable controller), the separator can obtain different separation and slag discharge time according to different quality of oil in the working process. It can meet the requirements of different raw oils to the greatest extent and achieve the best separation effect. 7. Automatic controller The automatic controller is composed of PLC controller, display and control box. Please read the manual of the automatic controller for its principle and operation instructions.
