Abstract
The utility model relates to a rotor end-surface sealing surface of an internal mixer, which comprises an oil cylinder (1), a shifting fork (3), a fixed ring (7) and a movable ring (9), ad is characterized in that a cylinder seat (2) of the hydraulic oil cylinder (1) is connected with the shifting fork (3); and the shifting fork (3) is provided with a supporting part (5), a pressure pin (8) is installed on the end part of the shifting fork (3), and the pressure pin (8) is sequentially contacted with the fixed ring (7) and the movable ring (9). Compared with the traditional structure, the rotor end-surface sealing device has the advantages that the sealing effect is good, the installation and the repairing are convenient, the service life is long, and the like.
Description
Technical field
The utility model relates to a kind of banbury, is a kind of closed-smelting machine rotor face seals specifically.
Background technology
At present, the frequent face seals that adopts of banbury has both at home and abroad: mechanical type and hydrodynamic seal.Mechanical sealing, the moving adjusting of armrest big nut compresses the dish spring and realizes being adjacent to of sealing surface, this structure can't accurately be set by the bigger and sealing load of the interference effect of human factor, add reasons such as the quality of dish spring unstable and service life is long, be prone to that the end face seal effect is bad to cause leaking or maintenance interval weak point influences problems such as production efficiency.Oil cylinder directly withstands on the fluid pressure type structure on the sealing surface, because banbury self space is narrow and small, causes installation and maintenance extremely inconvenient.
The utility model content
The utility model purpose provides a kind of good sealing effect, the closed-smelting machine rotor face seals of installation and maintenance convenience and long service life.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of rotor end-face sealing device of banbury comprises oil cylinder, shift fork, Ding Quan, moving-coil, and the cylinder seat of described hydraulic jack is connected with shift fork; On the described shift fork support component is installed, the shift fork afterbody is equipped with pad, and pad contacts successively with Ding Quan, moving-coil.
Described support component is a bolt.
Described back-up ring is provided with softening plant, and the outlet of described softening plant is at banburying chamber and rotor end-face gap location.
Described fixed circle is provided with lubricating arrangement, and the outlet of lubricating arrangement is in moving-coil and Ding Quan contact position.
This rotor end-face sealing device compares with traditional structure that to have a sealing effectiveness good, and advantages such as long service life are installed and easy to maintenance.Do not have influence on result of use, when having guaranteed service property (quality), shortening maintenance cycle greatly, improving operating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the lubricated and softening plant of the utility model;
Fig. 3 is the scheme of installation of the utility model on banbury.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, banbury hydraulic pressure fork type rotor end-face sealing device is mainly by part oil cylinder 1, shift fork 3, and pivot bolt 5 encloses 7 surely, pad 8, moving-coil 9 parts such as grade are formed.Oil cylinder 1 and shift fork 3 are realized being rigidly connected by cylinder seat 2, and spring 4 provides pretightning force to use when the initial installation of this device.Hydraulic oil makes oil cylinder 1 drive shift fork 3 and encloses 7 power that apply left by pivot bolt 5 surely by 8 pairs of pads, makes it be adjacent to moving-coil 9, reaches the purpose of sealing.
If moving-coil 9, enclose 7 configuration surely and be suitable for oil-free lubrication, can not inject lubricating oil, otherwise inject thin oils and be lubricated by enclosing 7 surely on moving, fixed circle surface.By high-pressure oil pump supplying lubricating oil and softening agent; Described back-up ring 6 is provided with softening plant, and the outlet of described softening plant is at banburying chamber and rotor end-face gap location.Softening agent is injected into banburying chamber and rotor end-face gap location by the B mouth, on the one hand sizing material is stirred into starchiness, reaches one sealing; Reduce the caloric value of mixing process sealing ring on the other hand.Describedly enclose 7 surely and be provided with lubricating arrangement, the outlet of lubricating arrangement is at moving-coil 9 and enclose 7 contact positions surely.Lubricating oil is injected into moving-coil 9 and is enclosed 7 contact positions surely by the A mouth, mainly plays a part lubricated and sealing.This rotor end-face sealing device compares with traditional structure that to have a sealing effectiveness good, and advantages such as long service life are installed and easy to maintenance.
Four sealing surfaces of banbury two roots rotors are equipped with four groups of these sealing devices altogether.The hydraulic circuit of four sealing surfaces communicates, and guarantees the specific pressure unanimity of following in working order four sealing surfaces, has realized good sealing.Seal pressure can be regulated by the pressure of adjusting hydraulic oil, and along with fixed wearing and tearing of enclosing, pad makes that deciding circle continues to be adjacent to moving-coil automatically, has guaranteed sealing, has reduced frequency of maintenance.
