Abstract
The present invention is the improvement to disk centrifuge, and it is characterized in that deslagging pallet deslagging upper edge hole inner peripheral surface has hard wear-resistant material layer, deslagging tray bottom surface has the little pallet of ring-type, and there is hard wear-resistant material layer ring-type little pallet inner face neighboring.Thus substantially increase deslagging pallet slag-drip opening and deslagging pallet base angle wearability; reach sliding plunger protection pallet to be not easily worn; sliding plunger is made to protect pallet to be extended service life; even if containing solid particle particularly hard particles feed separation; still can keep the comparatively long life, 4-8 can be improved service life doubly.Unsettled section of cantalever motor has firewood to support, and is supported on the support of bottom, makes motor steadily of centre of gravity, running balance, avoids motor cantilever and is arranged on the lower High Rotation Speed of firewood supporting and produces the damage that high vibration causes, reach the object that equipment long-term stability is run.
Description
Technical field
The present invention is the improvement to disk centrifuge, particularly relates to the deslagging protection pallet of disk centrifuge, provides a kind of deslagging to protect pallet not easy to wear, the disk centrifuge of long service life.
Background technology
Disk centrifuge produces centrifugal force by High Rotation Speed (such as about 6600 revs/min), centrifugation machinery is carried out to different specific weight material in compound, after usual separation, deslagging still carries out in High Rotation Speed, by sliding up and down piston along disc type separator rotary drum perisporium during deslagging, the slag-drip opening opened under hydraulic action on rotatory drum wall realizes deslagging.And containing solid particle particularly some hard particles in some separation of material, sometimes solid phase particles content is up to 20 ~ 30%, and in high-speed rotation deslagging, the slag velocity of discharge is very high, flow velocity is up to about 180 meter per seconds, discharge from slag-drip opening so at a high speed containing solid phase particles slag, it washes away at a high speed and very easily causes sliding plunger slag-drip opening to wear and tear, prior art is protection sliding plunger, be typically employed in its surface and protection pallet is set, but high speed deslagging can cause protection pallet exit position to be easy to be worn equally, only about the one week thick stainless steel protection pallet short-term operation life-span of 2mm, then cause and close seal failure and leak, normal separation effect can not be played, therefore causing to change protects pallet frequent, and increase use cost, secondly, as forgotten replacing after the wearing and tearing of protection pallet, then can cause the wearing and tearing of sliding plunger, more, add use cost.
Secondly, disk centrifuge is in separation process, and solid-liquid mixture enters stock distributor by feed pipe, by taper seat and the outflow at a high speed of reinforcement intersection of stock distributor.Equally owing to containing solid particle particularly some hard particles in solid-liquid mixture; under high-speed material stream washes away; solid particle becomes strongly to wash away to sliding plunger surface protection tray bottom dihedral; protection pallet base angle very quick-wearing can be made equally; protection pallet mill seriously can be caused logical, and namely the thick stainless steel protection pallet of 2mm wore and tore, as changed not in time in one week; and then the sliding plunger that can wear and tear further, finally cause the damage of whole equipment.Reliable, the steady operation of these defect long-standing problem disk centrifuges, and make to use increase.
Besides, the centrifugation of disk centrifuge is rotated, and is be arranged on disk centrifuge support upper motor by transverse direction to provide power.Centrifugation rotating speed is up to about 6600 revs/min, high rotating speed like this produces huge effect of inertia, the longitudinal rotating shaft of disk centrifuge and centrifuge and bottom support support for this reason, the firewood of non-rigidity is all adopted to support, the supporting of centrifuge, be only that centrifuge body is arranged at bottom support by firewood supporting, make electrical installation be cantilever design form.And disk centrifuge power is usually larger, make adapted motor larger, motor cantilever is arranged, objectively easily formed and lay particular stress on the heart, add that whole supporting is the firewood supporting of non-rigidity, operationally High Rotation Speed very easily causes the centre-of gravity shift of whole equipment, thus causes disk centrifuge in operation process because centre-of gravity shift makes whole equipment produce high vibration, the long-time firewood that very easily damages supports, and causes life of equipment to shorten.
Above-mentioned deficiency still has the place being worth improving.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, is used in containing hard solid particle material centrifugation even if provide a kind of, also not easy to wear, the disk centrifuge of long service life.
The object of the invention realizes; main improvement one washes away position (upper edge hole) at protection pallet slag-drip opening by deslagging to apply hard wear-resistant layer; increased the service life by the wearability improving this position; two is have the little pallet of ring-type in the increase of deslagging tray bottom surface; there is hard wear-resistant material layer ring-type little pallet inner face neighboring; thus overcome the deficiencies in the prior art, realize the object of the invention.Specifically, disk centrifuge of the present invention, disk centrifuge, comprise the deslagging pallet on the surface that to set within it with sliding plunger similar shape, and the cantalever motor be horizontally placed on disk centrifuge, it is characterized in that said deslagging pallet deslagging upper edge hole inner peripheral surface has hard wear-resistant material layer, deslagging tray bottom surface has the little pallet of ring-type, and there is hard wear-resistant material layer ring-type little pallet inner face neighboring.
In addition, for making motor operate steadily, unsettled section of increase by the firewood supporting of motor being set at cantilever, making motor bearing in bottom support, form centre-of gravity shift when effectively avoiding cantilever motor to work, reach even running.
The said applying hard wear-resistant material of the present invention, its applying mode and material can not be limit, such as, can be hard chrome plating or edge, weldering high-abrasive material (diamond, CW alloy etc.).
Disk centrifuge of the present invention, relative to prior art, hard wear-resistant material layer is applied owing to washing away position (deslagging upper edge hole inner face) at deslagging pallet deslagging, deslagging tray bottom surface position increases the little pallet of ring-type, hard wear-resistant material layer is applied with little pallet inner face neighboring (washing away position by material), thus substantially increase deslagging pallet slag-drip opening and deslagging pallet base angle wearability, reaching sliding plunger protects pallet slag-drip opening and base angle to be not easily worn, sliding plunger is made to protect pallet to be extended service life, even if containing solid particle particularly hard particles feed separation, still can keep the comparatively long life, 4-8 can be improved service life doubly.
Below in conjunction with an exemplary embodiment; essence of the present invention is understood in exemplary illustration and help further; but embodiment detail is only in order to the present invention is described; do not represent the present invention and conceive lower whole technical scheme; therefore should not be construed as the technical scheme total to the present invention to limit; some are In the view of technical staff; the unsubstantiality not departing from the present invention's design increases and/or changes; such as simply change with the technical characteristic with same or similar technique effect or replace, all belonging to scope.
