Machine Introduction
Industrial dehydrators, also known as three-legged dehydrators, three-legged centrifugal dehydrators, centrifugal dehydrators, dehydration centrifuges, and industrial spin dryers, are dehydration machines widely used in dehydration processes. In industrial applications, they are suitable for dehydrating (deoiling) various metal parts after grinding, cutting, oil washing, water cleaning, cooling, and anti-rust liquid dipping. They are also applicable for drying, dehydrating, and deoiling small hardware parts, electronic components, iron filings, aluminum filings, and copper filings; dehydrating textiles, clothes, cotton, linen, silk, etc.; and used in electroplating and grinding plants, hardware lathe processing plants, hardware fastener factories, etc. Centrifuges can be used for dehydrating various materials, such as gypsum, ammonium sulfate, mirabilite, ferric sulfate, copper sulfate, nickel sulfate, potassium sulfide, acetic acid, borax, soda, rubber additives, dyes, plastic particle raw materials, soap, grease, various resins, table salt, monosodium glutamate, food additives, starch sugar production, vitamins, antibiotics, herbicides, insect repellents, and dehydrating mineral powders of copper, zinc, aluminum, etc.
Working Principle
The working principle of a dehydrator is the same as that of the spin-drying tub of a washing machine—it is a machine that separates materials using centrifugal force. In a strong centrifugal force field, liquid seeps out of the rotating drum through the filter cloth. Blocked by the liquid baffle shell or liquid collection tank, the liquid flows out of the machine through the liquid outlet pipe. Solids are retained on the filter cloth. After the machine stops, the filter cloth is taken out and the solids are collected, completing one dehydration cycle.
Structural Features
1. All industrial centrifugal dehydrators adopt a three-legged suspension structure, which can effectively reduce the foot vibration caused by unbalanced loads in the rotating drum during operation.
2. The outer shell and inner drum are made of high-quality 304 stainless steel, ensuring sturdiness and durability.
3. The main shaft is made of high-quality steel and undergoes heat treatment and precision machining.
4. The transmission part adopts V-belt transmission. The motor directly drives the centrifugal starter wheel, allowing the machine to start slowly and gradually reach the designed rotation speed to ensure stable operation.
5. The machine is equipped with a brake opening-closing arm, which has good braking performance and can stop the machine quickly.
Operation Method
1. Place the machine on a horizontal ground. Ensure the ground is level and flat, and fix the machine with anchor bolts or expansion screws.
2. The machine uses 380V three-phase industrial electricity; phase failure must be avoided, otherwise the motor will burn out. The wiring method is delta connection. Ensure the inner drum rotates clockwise. Test the machine once after wiring. If the inner drum rotates counterclockwise, swap the wires on any two terminal posts.
3. When the machine runs idly and reaches a relatively high rotation speed, there will be a harsh wind noise, which is a normal phenomenon and will disappear after materials are added.
4. Depending on the material condition, you can choose to use a filter bag or not. If a filter bag is needed, place it in the inner drum, spread it flat, ensure the filter cloth is as close as possible to the side and bottom of the inner drum, and avoid large wrinkles. Tuck the excess filter cloth at the upper edge of the inner drum evenly into the gap between the outer shell and the inner drum.
5. Put the materials to be dehydrated into the inner drum evenly and flatly. If the materials are solid, ensure they are as flat and even as possible after loading. The loading volume must not exceed the maximum capacity of the machine.
6. Start the machine; it will reach the maximum rotation speed in about 15 seconds. If the machine vibrates severely during this process, cut off the power immediately and 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.
7. After the machine reaches the maximum rotation speed, a large amount of liquid will flow out from the drain pipe. After about 2 minutes, the materials are basically dehydrated, and almost no liquid flows out from the drain pipe. At this point, turn off the power. After half a minute, apply intermittent braking (spot braking); do not brake to a stop at once.
8. After the machine comes to a complete stop, take out the materials and re-spread the filter cloth in the inner drum to start the next dehydration cycle.
9. Never add materials while the machine is running, to prevent the high-speed rotating drum from throwing the materials out and causing injury. Do not brake to a stop at once; instead, apply intermittent braking several times to stop the machine.
10. After the machine has been running for several months, if the braking becomes ineffective, replace the brake pads; if the machine speed is obviously lower than the constant speed, replace the centrifugal weights.
Applicable Industries
1. Food industry: Dehydration of processing raw materials, vegetables, grains, starch, etc.
2. Service industry: Spin-drying and dehydration of clothes, bed sheets, etc., dehydration of textiles, decolorization liquid removal from textiles, etc.
3. Other industries: Dehydration and separation of materials that require dehydration.
Daily Operation and Maintenance
1. Operators must be familiar with the machine's structure, performance, and operation method.
2. Before starting the machine, rotate the drum several times to check its operation status.
3. Materials should be loaded evenly to avoid excessive vibration caused by severe imbalance.
4. Do not brake the opening-closing arm during normal operation, to prevent damage to the bearing belt and other parts.
5. Do not place any items on the top cover to avoid accidents after the machine is started.
6. If any abnormal phenomenon is found during operation, cut off the power immediately, apply braking to stop the machine, and conduct an inspection.
7. The machine must be overhauled regularly and lubricating oil added; it should be overhauled at least once every six months.
