Abstract
The utility model relates to an improved disc type separator, which is characterized in that the inner peripheral surface of the deslagging upper-edge of a deslagging tray is provided with a hard wear-resistant material layer, the bottom surface of the deslagging tray is provided with a small annular tray, and the peripheral edge of the inner surface of the small annular tray is provided with a hard wear-resistant material layer. Thus, the abrasive resistance of the deslagging port of the deslagging tray and the base angle of the deslagging tray are greatly increased, a sliding piston protection tray is not easily abraded, and the service life of the sliding piston protection tray is prolonged. Even if the disc type separator separates the materials containing solid particles, particularly hard particles, the disc type separator can still keep a longer service life, and the service life can be increased by 4-8 times.
Description
Technical field
Utility model is the improvement to disk centrifuge, relates in particular to the deslagging protection pallet of disk centrifuge, provides a kind of deslagging protection pallet not easy to wear, the disk centrifuge of long service life.
Background technology
Disk centrifuge is to produce centrifugal force by High Rotation Speed (for example about 6600 rev/mins), different specific weight material in the compound is carried out centrifugation machinery, usually deslagging still carries out in High Rotation Speed after separating, by sliding up and down piston along disk centrifuge rotary drum perisporium, the slag-drip opening of opening under hydraulic action on the rotatory drum wall is realized deslagging during deslagging.And contain particularly some hard particles of solid particle in some separation of material, sometimes solid phase particles content is up to 20 ~ 30%, and in the High Rotation Speed process deslagging, the slag velocity of discharge is very high, flow velocity up to 180 meter per seconds about, containing the solid phase particles slag discharges from slag-drip opening so at a high speed, it washes away at a high speed and very easily causes the wearing and tearing of sliding plunger slag-drip opening, prior art is the protection sliding plunger, usually adopt and on its surface the protection pallet is set, but the high speed deslagging can cause protection pallet outlet position to be easy to be worn equally, the thick stainless steel protection pallet short-term operation life-span of 2mm is only about a week, then causes to close seal failure and leak, and can not play the normal separation effect, therefore cause to change and protect pallet frequent, and increase use cost; Secondly, replacing then can cause the wearing and tearing of sliding plunger, the upper use cost that increased as forgetting after the wearing and tearing of protection pallet.
Secondly, disk centrifuge is in separation process, and solid-liquid mixture enters stock distributor by feed pipe, is flowed out at a high speed by taper seat and the reinforcement intersection of stock distributor.Same owing to containing particularly some hard particles of solid particle in the solid-liquid mixture; wash away lower at high-speed material stream; solid particle becomes strongly to wash away to sliding plunger surface protection tray bottom dihedral; can make equally very quick-wearing of protection pallet base angle; seriously can cause protection pallet mill logical, the thick stainless steel protection pallet of 2mm is i.e. wearing and tearing in one week, such as untimely replacing; and then the sliding plunger that can further wear and tear, cause at last the damage of whole equipment.These defectives perplex reliable, the steady operation of disk centrifuge for a long time, and so that use increase.
Above-mentioned deficiency still has is worth improved place.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, and is also not easy to wear even provide a kind of use containing hard solid particle material centrifugation, the disk centrifuge of long service life.
Another purpose of utility model is to provide a kind of and uses the longevity more to order long disk centrifuge.
Utility model the first purpose realizes; the main improvement is to be subjected to deslagging to wash away position (upper edge hole) at protection pallet slag-drip opening to apply hard wear-resistant layer; increase the service life by the wearability that improves this position, thereby overcome the deficiencies in the prior art, realize the utility model purpose.Specifically, the utility model disk centrifuge, comprise with the sliding plunger similar shape set within it the surface the deslagging pallet, it is characterized in that said deslagging pallet deslagging upper edge hole inner peripheral surface has the hard wear-resistant material layer.
Utility model the second purpose realizes; in the increase of deslagging tray bottom surface the little pallet of ring-type is arranged; be applied with the hard wear-resistant material layer in the little pallet inner face of ring-type neighboring (being subjected to material to wash away the position); thereby make disk centrifuge taper seat and reinforcement intersection through distributor in separation process go out at a high speed material; be flushed on the hard wear-resistant material layer of little pallet; protect the pallet base angle to be difficult for wearing and tearing, reached the prolongation deslagging pallet purpose in service life.
The said hard wear-resistant material that applies of utility model, it applies mode and material can not limit, such as being hard chrome plating or edge, weldering high-abrasive material (diamond, CW alloy etc.).
The utility model disk centrifuge, with respect to prior art, because washing away position (deslagging upper edge hole inner face) at deslagging pallet deslagging applies the hard wear-resistant material layer, thereby has greatly improved the wearability at this position, reach sliding plunger protection pallet and be difficult for being worn; In addition; the increase of deslagging tray bottom surface has the little pallet of ring-type; be applied with the hard wear-resistant material layer in little pallet inner face neighboring (being subjected to material to wash away the position); protected deslagging pallet base angle to be difficult for wearing and tearing; these are all so that sliding plunger protects pallet to be prolonged service life; even containing particularly hard particles feed separation of solid particle, still can keep than the long life, can improve 4-8 service life doubly.
Below in conjunction with two exemplary embodiments; utility model essence is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent the lower whole technical schemes of utility model design; therefore should not be construed as the total technical scheme of utility model is limited; some are In the view of the technical staff; the unsubstantiality that does not depart from the utility model design increases and/or change; for example change or replace so that technical characterictic with same or similar technique effect is simple, all truely use novel protected scope.

The specific embodiment
Embodiment 1: referring to Fig. 1,2; the utility model disk centrifuge; comprise seperator main body 1; rotary drum perisporium sliding plunger 2; sliding plunger inner surface similar shape is provided with deslagging protection pallet 3, and deslagging protection pallet deslagging upper edge hole inner peripheral surface has hard wear-resistant material layer 4 (for example hard chrome plating or edge, weldering high-abrasive material).
Embodiment 2: referring to Fig. 3,4, as aforementioned, in deslagging protection pallet 3 bottom surfaces the little pallet 5 of ring-type is arranged, there is hard wear-resistant material layer 6 (for example hard chrome plating or edge, weldering high-abrasive material) the little pallet inner face of ring-type neighboring.
To those skilled in the art; under this patent design and specific embodiment enlightenment; some distortion that can directly derive or associate from this patent disclosure and general knowledge; those of ordinary skills will recognize also can adopt additive method; or the substituting of known technology commonly used in the prior art; and the equivalence of feature changes or modification; mutual various combination between feature; the for example change of wearing layer material; etc. unsubstantiality change, can be employed equally, can both realize this patent representation function and effect; launch for example no longer one by one to describe in detail, all belong to this patent protection domain.
