Product Introduction
Introduction to Flat Plate Hermetic Centrifuge
The PB series flat plate hermetic centrifuge, also known as flat plate centrifuge, flat plate top-discharge centrifuge, flat plate manual discharge centrifuge, and four-legged centrifuge, is a centrifugal dehydration equipment widely used in chemical, pharmaceutical, food, biological and other industries.
Compared with the PS series flat plate centrifuge, this model is equipped with an additional lid that can hermetically seal the machine. The lid can be fitted with a feed pipe, washing pipe, nitrogen pipe, lighting lamp, sight glass, etc., making it suitable for handling materials with characteristics such as volatility, corrosiveness, toxicity and harmfulness.
Structural Type
This model is a commonly used one in the flat plate centrifuge series. The machine adopts a flat plate structure, with components arranged from top to bottom as follows: machine lid, outer shell, rotating drum, motor, flat plate base, liquid discharge pipe, damping shock-absorbing legs, frequency conversion control cabinet, etc. The machine lid can be equipped with a feed pipe, washing pipe, explosion-proof lamp and sight glass according to requirements. The entire machine is made of stainless steel (the base plate is iron covered with stainless steel), and all parts in contact with materials are made of 304 or 316 stainless steel, which is acid-resistant, alkali-resistant and corrosion-resistant. The inner tank of the rotating drum is made of 4-6mm stainless steel. The motor can be an ordinary motor or an explosion-proof motor as required. The start and stop of the machine are controlled by a frequency converter, without wearing parts such as brake pads and starting plates. The machine has smooth structural transitions, and its surface is polished to eliminate hygiene dead corners, allowing thorough cleaning of the entire machine. Compared with three-legged centrifuges, the flat plate centrifuge has a simpler structure, more stable operation, lower failure rate, more convenient operation and higher hygiene standards.
Operation Method of Flat Plate Centrifuge
1. Place the machine on a horizontal ground. Ensure the ground is as level and flat as possible, with no gaps between the four shock-absorbing legs of the centrifuge and the ground.
2. Fix the machine by drilling holes and installing expansion screws according to the fixing holes on the shock-absorbing legs, or use other fixing methods.
3. Connect the frequency converter in accordance with the instructions on the frequency converter terminal posts. Test the machine once after wiring is completed. The startup method is: Turn on the power, then press the "Start" button on the frequency converter panel to check if the rotating drum rotates clockwise, and then press the "Stop" button to stop the machine. During this process, if the inner tank rotates counterclockwise, swap the positions of any 2 wires on the motor terminal posts to ensure the inner tank rotates clockwise.
4. Note: When the machine runs idly and reaches a relatively high speed, there will be a harsh wind noise, which is a normal phenomenon and will disappear after materials are added. When the machine stops, after pressing the "Stop" button, there will be a smell of burnt paint, which is caused by the heating of the braking resistor in the frequency converter and is a normal phenomenon. The braking resistor is a high-temperature component; do not touch it with your hands.
5. Place the filter bag in the inner tank and spread it flat. Ensure the filter cloth is as close as possible to the side and bottom of the inner tank, with no excessive wrinkles. Tuck the excess filter cloth at the upper edge of the inner tank evenly into the gap between the outer shell and the inner tank.
6. If the material is solid, put the materials to be dehydrated into the inner tank evenly and flatly, and ensure they remain as flat and even as possible after loading. If the material is fluid, it can be poured or pumped into the machine after the machine reaches maximum speed. Never add solid materials while the machine is running, to prevent the high-speed rotating drum from throwing the materials out and causing injury (except for fluid liquids). The loading volume must not exceed the maximum capacity of the machine.
Note: If the material is fluid, feed it in an appropriate and uniform manner to prevent the liquid in the water tank from overflowing from the bottom of the machine due to untimely discharge.
7. Press the "Start" button to start the machine; the machine will reach maximum speed within 180 seconds. Press the "Stop" button; the machine will stop within 180 seconds. If the machine vibrates severely during this process, press the stop button or cut off the power immediately to check if the materials are flat and even. After adjusting the materials to be flat and even, if vibration still occurs, stop the machine immediately and contact the manufacturer.
8. After the machine reaches maximum speed, a large amount of liquid will flow out from the drain pipe. After approximately 2 minutes, the materials will be basically dehydrated, and almost no liquid will flow out from the drain pipe. At this point, press the stop button.
9. After the machine comes to a complete stop, take out the materials and re-spread the filter cloth in the inner tank to start the next dehydration cycle.
Daily Maintenance of Flat Plate Centrifuge
Every 6 months of machine operation, grease should be added to the bearing chamber. The specific oil-filling method is: Remove the centrifuge's outer shell and rotating drum, open the bearing cover, add high-temperature resistant grease, and then reassemble the machine.
Industrial Applications of Flat Plate Centrifuge
1. Pharmaceutical industry: Dehydration and separation of pharmaceutical intermediates, dehydration and separation of chemical mother liquor, etc.
2. Chemical industry: Dehydration and separation of chemical products, dehydration and separation of chemical raw materials, dehydration and separation of intermediates, dehydration and separation of chemical mother liquor, etc.
3. Food industry: Dehydration of processing raw materials, vegetable dehydration, grain dehydration, starch dehydration, etc.
4. Oil industry: Impurity removal of industrial oil, cleaning of edible oil, etc.
5. Biological industry: Solid-liquid separation of biological fertilizers, biological pharmaceuticals, etc.
