Description

A kind of efficient disk centrifuge

Technical field

The utility model relates to isolation technics, is specifically related to a kind of disk centrifuge.

Background technology

The utility model utilizes technology relevant with heavy oil. present global oil shortage, and the high enterprise of oil price, and the boat diesel engine fuel consumption is very big, the operating cost of boats and ships increases severely.As the heavy oil of poor oil, low price utilizes centrifugal separation technology, the melt cinder that contains in the heavy oil is removed and is upgrade, and can make full use of the energy, also helps environmental protection.Existing disk centrifuge comprises the rotary drum that contains the separation chamber, with the coaxial mounted plate rail of rotary drum, the plate rail lower end is bell mouth shape, one group of copper frustoconical plate-like separate video disc stacked mutually at a certain distance with the rotary drum coaxial package on plate rail, the lower edge of video disc has the flanging of level.The problem that this structure exists is: owing to require absolute oil, water, soft slag to collect by proportion layering from top to bottom, heavy oil needs from bottom to top under action of centrifugal force from successively up between stacked video disc and layering, it is not high that the rotation of plate rail drives heavy oil rotary action power, and it is enough big that the centrifugal force that heavy oil produces can not reach; The horizontal flanging of video disc radially throws away heavy oil under action of centrifugal force, rather than upwards throws away; Video disc is made by copper material, and quality is softer, if run into little lump foreign material, is stuck in easily between the video disc and makes the video disc distortion, or make the rotary drum seal failure, and the problems referred to above all can cause the separative efficiency of heavy oil to reduce.

The utility model content

The purpose of this utility model is to overcome the problems referred to above, proposes a kind of efficient disk centrifuge that improves the heavy oil separative efficiency.

The purpose of this utility model can be achieved through the following technical solutions:

A kind of efficient disk centrifuge, comprise that the rotary drum that contains the separation chamber, one group of frustoconical plate-like video disc, bowl hood, neck cover, with the coaxial mounted plate rail of rotary drum, the plate rail lower end is bell mouth shape, the bell-mouthed inner surface that it is characterized in that plate rail is shaped on radially-arranged rib shape paddle, mutually stackedly is sleeved on video disc on the plate rail at a certain distance by the stainless steel material punch forming.

Described rib shape paddle is extended downwards outside the horn mouth of plate rail lower end.

The lower edge of described video disc has flange upwards.

Have through hole at interval on the conical surface of described video disc, be shaped on fin upwards between the through hole.

Be placed in the outer upper end of bowl hood and be shaped on the absolute oil outlet, the axis direction of absolute oil outlet and the axis direction of plate rail are 40 ℃ of-50 ℃ of angles.

Between plate rail seat in the described rotary drum and the rotary drum inner bottom surface alms bowl shape piston is housed, has cavity between alms bowl shape piston and the rotary drum inner bottom surface, when the cavity internal pressure raises, drive alms bowl shape piston and rise, make alms bowl shape piston upper limb will be arranged on the soft slag row mouthful sealing of rotatory drum wall portion.

Advantage of the present utility model is: the bell-mouthed inner surface of plate rail is shaped on radially-arranged rib shape paddle, and the rotation of paddle can drive the rotation of heavy oil effectively and produce centrifugal effect; The video disc of being made by stainless steel can improve intensity, increases the service life; The lower edge of video disc is to upper overturning, can quicken heavy oil creeping from bottom to top; The absolute oil outlet departs from the axis of plate rail, can prevent that absolute oil from mixing with assorted liquid generation; Above-mentioned resultant effect can improve the heavy oil centrifugal separating effect effectively, through test, original moisture separation rate 84% can be brought up to 92%, and the impurity separation rate brings up to 88% from 75%, has improved resource utilization.

The specific embodiment

The utility model comprises rotary drum 1, plate rail 6, video disc 3, is placed in the necks lid 4 outside the plate rail 6, be placed in the bowl hood 5 outside the neck lid 4, the upper end of neck lid 4 is shaped on absolute oil outlet 7, and the axis direction of absolute oil outlet 7 and the axis direction of plate rail 6 are 40 ℃ of-50 ℃ of angle theta, preferablely is 45 ℃ of angles.Gravity ring 9 is equipped with in the upper end of bowl hood 5, and along being shaped on outlet of sewer 8, the sidewall of rotary drum 1 has soft slag row mouth 11 in the gravity ring 9.Between plate rail seat 2 in the rotary drum 1 and rotary drum 1 inner bottom surface alms bowl shape piston 15 is housed, has the cavity that communicates with rotary drum 1 bottom through-hole 17 between alms bowl shape piston 15 and rotary drum 1 inner bottom surface, when pressure enters from through hole 17, the cavity internal pressure raises, drive alms bowl shape piston 15 and rise, make alms bowl shape piston upper limb will be arranged on soft slag row mouthful 11 sealings of rotatory drum wall portion; When from through hole 17 releases, alms bowl shape piston 15 descends, and the soft slag row mouthfuls 11 of rotatory drum wall portion is opened, and can carry out the deslagging operation.

Drive conical surface vertical shaft 10 and rotary drum 1 and interior plate rail seat 2, plate rail 6 forms and be in transmission connection by variable speed electric motors, particularly, multi-disc is formed the combination video disc by the separation video disc 3 of stainless steel material punch forming, the cover build up have ask the crack coaxial package on plate rail 6, and the cooperation by keyway 34 and rotate synchronously with rotary drum 1, the gap forms by having the fin that makes progress 31 that is shaped between the through hole 33 at interval on the video disc conical surface, these fins 31 is set can presses closer the lower surface of adjacent video disc so that form flow channel between video disc.Each video disc 3 is the frustoconical plate-like, and the lower edge of video disc has flange 32 upwards, and through hole 33 also can axially form a line, thereby forms a lot of axial passages by video disc; The lower end that is the plate rail 6 of hollow form is horn mouth 61, and bell-mouthed inner surface one is shaped on radially-arranged rib shape paddle 62.The heavy oil that the need work separates is entered by the upper port of plate rail 6; when heavy oil enters the gap of flowing through between the video disc by plate rail 6; solid particle is deposited under the centrifugal action of rotation at a high speed and forms sediment on the video disc; sediment slides and breaks away from video disc and accumulate in bottom in the rotary drum in disc surface; can after seperator stops, take rotary drum apart, or under non-stop-machine situation, discharge from the soft slag row of rotary drum mouth 11 by slagging device by artificial removing.The medium moisture of separated proportion is discharged from outlet of sewer 8; The absolute oil of proportion minimum is discharged from absolute oil outlet 7.
