Description

A kind of novel centrifugal seperator

Technical field

The utility model relates to a kind of novel centrifugal seperator.

Background technology

Centrifugal separator is mainly used in the solid particle in suspension and liquid to separate; Or by two kinds of density differences in emulsion, immiscible liquid separates (for example from milk, isolating cream) again; It also can be used for getting rid of the liquid in wet solid, for example, with washing machine, dry wet clothes; Special hypervelocity channel separator is the admixture of gas of separable different densities also, for example concentrated, separating gaseous hex; The different feature of solid particle sinking speed in liquid of utilizing different densities or granularity, some sedimentation centrifuges 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.

China Patent No.: 201110235699.6 disclose a kind of bottom-transmission liquid-liquid centrifugal separator, comprise motor, transmission device, rotary drum, seperator shell and upper cover, rotary drum is arranged in seperator shell, upper cover is placed on seperator shell, motor connects rotary drum by transmission device, in rotary drum, be provided with light phase weir and heavy phase weir, between light phase weir and heavy phase weir, be provided with heavy phase weir baffle plate, between rotor cover and seperator shell, be provided with heavy phase collecting ring and light phase collecting ring, on the seperator shell of heavy phase collecting ring top, be provided with heavy out, on seperator shell between heavy phase collecting ring and light phase collecting ring, be provided with light phase export, bottom at seperator shell is provided with charging aperture, in seperator shell rotary drum below deflector is set.This invention can by the liquid-liquid mixture of different specific weight continuously fast separated, improved disposal ability, and be convenient to more commutation weir and maintenance of equipment.But the wearing and tearing at its transmission position are very serious in actual production application, keep in repair also very frequent.

The wearing and tearing of transmission position are the ubiquitous problems of centrifugal separator, and quantity is larger, damage frequently, and comprising positions such as centrifugal separator bearing position, bearing blocks, how to address this problem is the technology perplexing in industry always.

Utility model content

Therefore, for above-mentioned problem, the utility model proposes a kind of simple in structure, can effectively prevent bearing wear, reduce the novel centrifugal seperator of frequency of maintenance.

For achieving the above object, the utility model has adopted following technical scheme: a kind of novel centrifugal seperator, comprise fuselage, be located at rotating shaft on fuselage, drive shaft drive unit, be located at the rotary drum that is positioned at fuselage in rotating shaft, more than one step is located at respectively at the two ends of described rotating shaft, on described each step, be respectively equipped with and be located at taper roll bearing, described fuselage is provided with a bearing block, and described each taper roll bearing is located in bearing block respectively.

Further, be provided with to the corresponding rotating shaft in the upper and lower two ends of described fuselage shaft seat, on described each shaft seat, be respectively equipped with the first ball recess, the two ends up and down of described rotating shaft are respectively equipped with the second ball recess, and described the first ball recess is connected by a ball with the second ball recess.

Further, in the bearing block of described fuselage below, be provided with machine oil, the oil level face of described machine oil is higher than the first ball recess of fuselage below.

Further, the upper end of described bearing block is an inclined-plane, between described bearing block and rotating shaft, is provided with sealing ring.

By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: compare with existing centrifugal separator, this novel centrifugal seperator is by arranging step in rotating shaft, the mode of taper roll bearing is set on step, radial load by original rotating shaft to bearing, resolve into the addition of axial force and radial load, reduced the effect of radial load, thereby wearing and tearing have been reduced, and utilize the mode of step, make force resolution by two ends to centre gradually layer-transferred decompose, reduced stress, protected better rotating shaft and bearing; Further, by ball, rotating shaft is connected with fuselage, makes the axial force of rotating shaft be passed to fuselage, thereby reduced the load of bearing, and utilize the rotary action of ball, can complete more with flying colors the rotation of rotating shaft, make running more stable; Further, the upper end of described bearing block is an inclined-plane, between described bearing block and rotating shaft, be provided with sealing ring, by such arranging, can prevent that the liquid that the sealing on taper roll bearing top does not closely cause from penetrating in taper roll bearing, causes the reduction in service life downwards.
