Abstract
The utility model relates to a sealing device, which is a device for sealing the rotary drum body and the piston of the disc separator, comprising a rotary drum body and a piston. A rubber piston sealing ring is arranged between the rotary drum body and the piston in radial direction, a polymer material piston ring is arranged in front of the rubber piston sealing ring. When the disc separator separates normally, the ex-circle of the polymer material piston ring is closely attached with the inner wall of the piston by the centrifugal force, so the rigidity of the polymer material piston ring is high, which can effectively intercept hard slag particles, and the rubber piston sealing ring has a good sealing effect to the liquid, therefore, the problem of sealing piston ring when the separated materiel has a few particle hard slag similar to the metal powder is solved.
Description
Technical field
The utility model relates to a kind of sealing device, specifically disk centrifuge rotary drum body and piston sealing device.
Background technology
At present, the disk centrifuge rotary drum has many patterns, and the outer piston drum structure is to use more a kind of structural shape, can be used for mixed liquor density greater than 1.1g/cm
3Material liquid-solid two be separated, have the function of timing automatic deslagging.Figure 1 shows that existing disk centrifuge drum structure schematic diagram, comprise rotary drum lid 1, main lock ring 2, rotary drum body 3, main seal ring 4, piston 6, annular seal space 7, spilled water hole 8,6 in rotary drum body 3 and piston radially are provided with rubber piston sealing ring 5, play the radial seal effect by rubber piston sealing ring 5.Rubber piston sealing ring 5 has adopted elastomeric material, because rubber piston sealing ring 5 moves up and down during deslagging, the better performances of rubber piston sealing ring 5 seal fluids, when containing a small amount of soft slag in the feed liquid, the sealing property of rubber piston sealing ring 5 also can reach requirement.But when containing grit in the feed liquid, the friction effect that rubber piston sealing ring 5 moves up and down during owing to deslagging, rubber piston sealing ring 5 surfaces are very easily damaged, thereby cause seal failure, and grit infiltrates annular seal space 7, stops up spilled water hole 8, thereby makes the rotary drum seal failure.
Summary of the invention
The purpose of this utility model is to propose a kind of when containing a small amount of metalloid particles of powder grit in separation of material, still can make the disk centrifuge rotary drum have the disk centrifuge rotary drum body and the piston sealing device of good seal performance.
The purpose of this utility model can be achieved through the following technical solutions:
Disk centrifuge rotary drum body and piston sealing device comprise rotary drum body, piston, and rotary drum body and piston space radially are provided with glue rubber piston packing ring, are provided with the macromolecular material piston ring before the glue rubber piston packing ring.
The purpose of this utility model can also further realize by following technical measures:
Aforesaid disk centrifuge rotary drum body and piston sealing device, wherein said macromolecular material piston ring is the nylon piston ring.
Aforesaid disk centrifuge rotary drum body and piston sealing device, wherein said macromolecular material piston ring is provided with slant cutting edge.
Before the rubber piston sealing ring, increase a macromolecular material piston ring, when normal separation, this macromolecular material piston ring is under centrifugal action, cylindrical and piston inner wall fit tightly, because of its hardness higher, can effectively tackle the grit particle, the rubber piston sealing ring has good sealing function again to liquid, has so just solved the piston ring packing problem when containing a small amount of metalloid particles of powder grit in the separation of material.
Advantage of the present utility model is: fit tightly the effect of the grit particle that plays interception metalloid powder by macromolecular material piston ring excircle and piston inner wall, thereby prevent the damage that the grit particle causes rubber piston sealing ring surface.In addition, the rubber piston sealing ring again can be as before to liquid and contain a small amount of soft slag liquid and have good sealing function, thereby still has good sealing property when making the disk centrifuge rotary drum in separation of material, contain a small amount of metalloid particles of powder grit, sealing property is improved, and has also obtained prolongation service life.

The specific embodiment
Embodiment one
The drum structure of present embodiment as shown in Figure 1, the rotary drum parts comprise rotary drum lid 1, main lock ring 2, rotary drum body 3, main seal ring 4, piston 6, annular seal space 7, spilled water hole 8,6 in rotary drum body 3 and piston radially are provided with rubber piston sealing ring 5, play the radial seal effect by rubber piston sealing ring 5.Be provided with a macromolecular material piston ring 9 in the front of rubber piston sealing ring 5, macromolecular material piston ring 9 is a nylon ring, and its structure as shown in Figure 3.Disk centrifuge is when normally separating, and this macromolecular material piston ring 9 is under centrifugal action, and cylindrical and piston 6 inwalls fit tightly, and macromolecular material piston ring 9 is a nylon ring, and nylon ring hardness is higher, can effectively tackle grit.But nylon ring does not have the such elasticity of elastomeric material, and whole ring-type dress does not advance in the sealed groove of rotary drum body 3, and whole ring-type nylon ring can not guarantee to fit tightly with the inwall of piston 6 simultaneously.On nylon ring, be provided with slant cutting edge 10 one, so just nylon ring can be installed into the sealed groove of rotary drum body 3.When disk centrifuge ran well, owing to be subjected to action of centrifugal force, nylon ring opened outwardly, and the inwall of the outer wall of nylon ring and piston 6 fits tightly like this, had guaranteed the ability of interception grit.Nylon ring combines with rubber piston sealing ring 5, has guaranteed the sealing of rotary drum body 3 with piston 6, has prolonged the service life of rubber piston sealing ring 5.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
