Abstract
The invention provides an anti-vortex rotary drum used for a centrifugal machine and aims at solving the problems that existing rotary drums drive materials to rotate and are prone to generate strong vortex during high-speed rotation, and separation effect is not ideal. The anti-vortex rotary drum used for the centrifugal machine comprises a rotary drum body connected with a driving shaft, a set of energy dissipation plates are arranged in the rotary drum body, and a set of energy dissipation holes are arranged on the energy dissipation plates. The anti-vortex rotary drum used for the centrifugal machine is used for solid-liquid separation.
Description
Technical field
The present invention relates to a kind of chemical machinery, be specifically related to the anti-eddy current rotary drum of a kind of centrifugal separating machine.
Background technology
Centrifugal separator is to utilize centrifugal force, and the machinery of each component in the mixture of separating liquid and solid particle or liquid and liquid, centrifugal separator are mainly used in the solid particle in the suspension and liquid are separated; Or with two kinds of density differences in the emulsion, immiscible liquid separately utilizes the different characteristics of solid particle sinking speed in liquid of different densities or granularity again, and the sedimentation centrifuge that has also can carry out classification by density or granularity to solid particle.Centrifugal separator is widely used in the departments such as chemical industry, oil, food, pharmacy, ore dressing, coal, water treatment and boats and ships.As a rule the solids in suspension particle more segments from more difficult, and the fine grained of taking away in filtrate or the parting liquid can increase.In this case, centrifugal separator need to have higher separation factor effectively to separate.When liquid viscosity was large in the suspension, separating rate slowed down.The density contrast of suspension or each component of emulsion is large, and is favourable to centrifugal sedimentation, and suspension centrifugal filtration does not require that then each component has density contrast in order to strengthen separating property, generally adopts and improves the rotary drum rotating speed; Increase the time lengthening that new motive force or increase rotary drum length are separated centrifugal sedimentation in centrifugal separation processes, but will certainly increase like this volume of equipment, increase the device fabrication cost, and take up an area greatly, the factory building investment is large.
Centrifugal separator has one to be called rotary drum around the cylinder of axis High Rotation Speed own, usually by Motor Drive.After suspension (or emulsion) adds rotary drum, driven and the synchronized rotation of rotary drum rapidly, each component is separated under centrifugal action, and discharges respectively.Usually, the rotary drum rotating speed is higher, and separating effect is also better.But produce easily very strong eddy current because rotary drum drives the material rotation in the process of High Rotation Speed, its separating effect is undesirable.
Summary of the invention
The objective of the invention is provides a kind of centrifugal separating machine to prevent the eddy current rotary drum for the problem of above-mentioned existence, avoids the rotary drum of centrifugal separator to produce eddy current in the process of High Rotation Speed, improves the purity of separating, and shortens disengaging time.
Above-mentioned purpose is achieved through the following technical solutions:
Centrifugal separating machine is prevented the eddy current rotary drum, comprises the rotary drum body that is connected with driving shaft, and one group of energy dissipating plate is installed in described rotary drum body the inside, has one group of energy dissipating hole on the described energy dissipating plate.
Described centrifugal separating machine is prevented the eddy current rotary drum, and described energy dissipating plate is continuous slab or the intercostal plate parallel with described rotary drum body.
Described centrifugal separating machine is prevented the eddy current rotary drum, described energy dissipating plate is take described driving shaft as the axle center hierarchal arrangement, is positioned at the density in the energy dissipating hole on the described energy dissipating plate of internal layer take described driving shaft as the axle center greater than the density in the energy dissipating hole on the outer field described energy dissipating plate.
Beneficial effect:
1, the present invention is provided with the energy dissipating plate in rotary drum, because the eddy current that produces in the accelerator can be effectively eliminated in the effect of energy dissipating plate, separation process can be carried out in the little situation of stirring smoothly, and do not need to obtain the adverse effect that powerful centrifugal force contends with strong eddy current with high rotating speed, so the machine rotating speed lower (generally turning following at per minute 1,000).Like this, all revolving parts do not need the very high accuracy of manufacture, do not need the balance correction of very fine yet, need not adopt special bearing yet, and cylinder inner wall need not serve as a contrast special wear-resisting steel plate yet, and power of motor reduces a lot, Gu cost and use cost decrease.
2. the present invention can adopt continuous energy dissipating plate when the density difference of two kinds of materials that need to separate is less, suitably improve the rotating speed of complete machine, the density of two kinds of materials that separate when needs can adopt the energy dissipating plate at interval in the time of large, suitably reduce the rotating speed of complete machine, it is obvious to eliminate venturi effect.
3. energy dissipating plate of the present invention can adopt take described driving shaft as the axle center hierarchal arrangement, is positioned at the density in the energy dissipating hole on the described energy dissipating plate of internal layer take described driving shaft as the axle center greater than the density in the energy dissipating hole on the outer field described energy dissipating plate.Hierarchal arrangement is conducive to the successive elimination eddy current, and is more applicable for two kinds of poor less separation of material density, good separating effect.
4. the present invention is simple in structure, maintenance, easy to clean, and lightweight, cost is low.
