Abstract
The utility model discloses a centrifuge with multiple external motors. The centrifuge with multiple external motors comprises a base seat, and a centrifugal machine which is arranged above the base seat, wherein the centrifugal machine mainly comprises a centrifugal driven component and the motors connected with the centrifugal driven component. The centrifuge with multiple external motors has the advantages of reducing vibration because of an added anti-vibration cushion, effectively preventing the motors from being damaged because the motors are placed outside, and increasing areas of thrust surface of an outer cylinder due to the fact that a coupling screw is fixed far away from the outer cylinder.
Description
Technical field
The utility model relates to the centrifuge that Chemical Manufacture is used, and specifically refers to a kind of a plurality of external motor centrifuge.
Background technology
Centrifuge is to utilize centrifugal force, the machinery of each component in the mixture of separating liquid and solid particle or liquid and liquid.Centrifuge is 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 separates (for example isolating cream from milk) again; It also can be used for getting rid of the liquid in the wet solid, for example dries wet clothes with washing machine; Special hypervelocity channel separator is the admixture of gas of separable different densities also; Utilize the different characteristics of solid particle sinking speed in liquid of different densities or granularity, the sedimentation centrifuge that has also can carry out classification by density or granularity to solid particle.
Centrifuge is widely used in the departments such as chemical industry, oil, food, pharmacy, ore dressing, coal, water treatment and boats and ships.
Ancient Chinese, people hitch terrine with an end of rope, hold the other end of rope, and rotation whipping terrine produces centrifugal force and squeezes out honey in the terrine, the early stage application of centrifugation principle that Here it is.
Industrial centrifugal machine is born in Europe, such as in the middle of the 19th century, the link-suspended basket centrifuge of textile dehydration usefulness successively occurs, and the suspended centrifuge used of sugar refinery's fractional crystallization granulated sugar.These centrifuges the earliest all are intermittently operated and artificial deslagging.
Because the centrifuge of continued operation the thirties in 20th century appearred in the improvement of slag dumping mechanism, the intermittently operated centrifuge is also developed because having realized automatic control.
Industrial centrifuge can be divided into filtering centrifuge, sedimentation centrifuge and seperator three classes by structure and separation requirement.
Centrifuge 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.
The action principle of centrifugal separator has two kinds of centrifugal filtration and centrifugal sedimentations.Centrifugal filtration is the centrifugal pressure that suspension is produced under centrifugal force field, acts on the filter medium, make liquid become filtrate by filter medium, and solid particle is trapped within the filter medium surface, thereby realizes liquid-solid separation; Centrifugal sedimentation is the principle of utilizing each different component of suspension (or emulsion) density rapid sedimentation layering in centrifugal force field, realizes that liquid-solid (or liquid-liquid) separates.
The seperator that also has a class experimental analysis to use can carry out liquid clarification and solid particle enrichment, or liquid-liquid separation, and this class seperator has the different structure type that operates under normal pressure, vacuum, the freezing conditions.
The important indicator of weighing the centrifugal separator separating property is separation factor.It represents separated material suffered centrifugal force and ratio of its gravity in rotary drum, and separation factor is larger, usually separates also rapidlyer, and separating effect is better.The separation factor of industrial centrifugal separator is generally 100～20000, and the separation factor of hypervelocity channel separator can be up to 62000, and the separation factor of analyzing with the hypervelocity seperator is up to 610000.Another factor that determines the centrifugal separator disposal ability is the work area of rotary drum, and the large disposal ability of work area is also large.
Select the centrifuge fibrous root according to the characteristic of the density contrast of the size of solid particle in the suspension (or emulsion) and concentration, solid and liquid (or two kinds of liquid), liquid viscosity, filter residue (or sediment), and analysis-by-synthesis is carried out in the requirement that separates etc., satisfy the requirement to filter residue (sediment) water capacity and filtrate (parting liquid) clarity, which kind of centrifugal separator initial option adopts.Then by treating capacity and the automation requirement to operating, determine type and the specification of centrifuge, verify finally by actual tests.
Usually, for containing the suspension of granularity greater than 0.01 mm granules, can select filtering centrifuge; Tiny or compressible distortion for particle in the suspension, then should select sedimentation centrifuge; Contain that amount of solid is low, particle is small and liquid clarity is required should select seperator when high for suspension.
In the chemical industry bio-pharmaceuticals, owing in centrifugal process, usually have liquid material to overflow, in existing centrifuge, drive the below that all is provided in a side of centrifugal barrel to the motor of power, when liquid material is overflowed, can damage motor.The structure of grievous injury motor usually can cause centrifugal production line to stop and not operate, for this reason, we need to arrange a kind of can be with the sedimentator structure of electric machine external.
In general centrifugation apparatus, general adopt be one independently motor be rotated, conventional is the below that motor is arranged on staving.The height of main whole equipment increases, and then can cause the center of gravity of whole equipment to increase, and for the centrifugal design of jumbo chemical industry, is disadvantageous.Usually can cause centrifugal inner core and outer barrel to produce a large amount of frictions, damage equipment.For this reason, there is the people that motor side is moved, motor is arranged on the sidewall of urceolus, so still, an individual motor that adopts, such design can overcome the problem that center of gravity increases, and has brought simultaneously another new problem, be exactly centre-of gravity shift bucket axis, cause vibrations asymmetric.Need powerful staple, could reduce vibration amplitude.
For we need to overcome above-mentioned two kinds of shortcomings, could prolong life cycle and the service life of whole equipment.
