Disc Centrifuge

Description

There are many types of disc centrifuges, but in terms of the essence of their separation process, they can be basically divided into two processes: centrifugal clarification and centrifugal separation. The disc centrifuge can quickly and continuously separate solid-liquid and liquid-liquid, and is a type of vertical centrifuge. It is mainly suitable for the separation and clarification of materials with solid content less than 5% and solid phase particle diameter greater than 0.5 microns.

It is widely used in the extraction of tetracycline, penicillin, vaccine and insulin in pharmaceutical factories, the clarification of oral liquid, the separation and clarification of fermentation liquid in fermented brewing products, the collection of bacteria in the field of microorganisms, and the regeneration of lubricating oil in the chemical industry. Oil-water separation, biodiesel, dairy separation, and liquid-solid or liquid-liquid-solid separation of other materials.

Working Principle

The separated material is fed into the heart of the machine, that is, the inside of the drum. Under the action of strong centrifugal force, the material (mixed liquid) passes through the interval of a group of disc bundles. The large liquid (heavy phase) moves along the disc wall to the outside of the neutral hole, where the heavy slag accumulates in the sediment area, and the heavy phase flows to the large centripetal pump. The liquid with lower specific gravity (light phase) moves inwards and upwards along the disc wall and converges at the small centripetal pump. The light and heavy phases are output by the small centripetal pump and the large centripetal pump, respectively.

①The mixed liquid enters the disc centrifuge from the liquid inlet
②Solid particles settle on the surfaces of multiple discs
③The clean liquid moves continuously to the upper port of the centrifugal chamber
④The light liquid is pumped out of the outlet by the centripetal pump
⑤ The heavy liquid is pumped out by the heavy phase centripetal pump
⑥Separate solid impurities to the inner wall of the drum (manual discharge or self-discharge)

Features

  • Stable operation, low vibration and low noise when working.
  • All parts of the disc centrifuge in contact with the material are made of stainless steel, which can effectively reduce the corrosive effect of the separated material and meet the requirements of food hygiene.
  • Equipped with a stationary light and heavy phase discharge centripetal pump. The separated light and heavy two-phase materials are respectively output by the light and heavy phase centripetal pumps at the top of the drum, and the light phase enters the next process.
  • The power transmission of the disc centrifuge adopts a hydraulic coupling and a pair of helical speed-up gears, and uses liquid to transmit the power, which not only increases the speed smoothly but also provides overload protection.
  • The disc centrifuge is equipped with an automatic control cabinet. It is composed of industrial computer and machine overload automatic protector, etc. It has a high degree of automation, strong adaptability to process adjustment, convenient adjustment, and can greatly reduce the operation intensity of workers.

Model

Application

  • Milk separator: for milk skimming or clarification (solid impurity removal). The small separator is driven with labor aid and drain manually, suitable for domestic use of farmers and herdsmen. Large separators are driven electrically and ideal for industrial production.
  • Mineral oil separator: for the removal of water and mechanical impurities from mineral oil, including fuel oil, diesel oil, lubricating oil and transformer oil. It is also able to separate similar emulsion.
  • Plant oil separator: the processing and refinement of plant oil.
  • Animal oil separator: used to refine animal oil in meat processing or to concentrate and separate fish oil in aquatic processing
  • Yeast separator: to concentrate the yeast
  • Starch separator: for starch removal and starch concentration.
  • Wool fat separator: in the wool industry to extract wool grease from wool washing water.
  • Pharmaceutical disc separator: used in the pharmaceutical industry for the extraction of antibiotics, vitamins, etc. It is also suitable for the
    3- phase mixture separation in pharmaceutical and chemical production.
  • Beer separator: for the clarification of beer, wort and other beverages.
  • Latex separator: used for the concentration of rubber milk and the removal of impurities from rubber milk.
  • Paint separator: to separate the impurities in the paint, improving the quality of the color.
