The structure and working principle of the centrifugal separator The structure of the centrifugal separator has been described. It is a plan view of the centrifugal separator, and the physical diagram of the centrifugal separator is a working principle diagram of the centrifugal separator. There are tens to hundreds of a same shape and size, the taper angle of the tapered discs 6O 0 ~ 120 0, the gap between the back surface of the disc with the strip to control the disc, the disc is generally within its drum The gap between them is about 0.5 to 2.5 mm. Each disc has a plurality of symmetrically distributed circular holes on a circumference spaced a certain distance from the axis. When a plurality of such discs are stacked, the corresponding circular holes form a vertical passage. When a mixture of two different heavy liquids (or a mixture of two mutually incompatible liquids) having a certain pressure and flow rate enters the centrifugal separator , the mixture passes through the disc due to the high-speed rotation of the disc group of the centrifugal separator After the vertical passage formed by the upper circular hole enters the gap between the discs, it is also rotated at a high speed and has centrifugal force. At this time, the difference of the centrifugal sedimentation speed obtained by the two different heavy liquids due to the difference in gravity is different between the gaps between the discs: the centrifugal sedimentation speed obtained by the heavy liquid is greater than the flow velocity of the subsequent liquid, trends outward movement, the movement in the gap within the outer channel between the discs, and successive sinker from the vertical passage to the circular wall of the drum; high grade small centrifugal sedimentation velocity is smaller than the flow rate of the liquid obtained subsequent liquid in a subsequent liquid Under the push, it is forced to flow in the opposite direction to the axis, move to the periphery of the inlet pipe of the drum, and is continuously discharged. Thus, two different heavy liquids are separated during the flow of the gap between the discs. Â The structure and working principle of the centrifugal separator The centrifugal separator is a centrifuge that separates two liquids with different weights or insolubles by different centrifugal sedimentation speeds. Compared with other separation methods, the centrifuge is simple and economical; but it still does not completely separate, but To concentrate on heavy liquid (or light liquid). Centrifugal separators can be realized by replacing different discs depending on the nature of the product or the need for one of two different heavy liquids (or two immiscible liquids). If the result of centrifugation is to collect heavy liquid and to ensure the quality of the heavy liquid, such as centrifugation of milk in the dairy industry in order to obtain high quality milk fat, there is no strict requirement for the ingredients in skim milk (ie, allow For a small amount of dispersing cream, use the opening in the disc at a distance of 2/3 from the axis as shown. If the result of the centrifugation is to collect the light liquid and to ensure the quality of the light liquid (high magnification is high), and the composition of the heavy liquid is not strictly required (the concentration is low), the opening on the disc can be used to leave at a distance. Position 1/3 of the axis, as shown |
