Description
Technical field
The present invention relates to rubber and plastic banbury technical field; the new structure of the outer pressure sealing device of especially a kind of banbury; it effectively can improve the service life of sealing effectiveness and stationary seal ring in sealing device; effectively reducing number of times and the time of banbury contaminated environment and minimizing banbury shutdown replacing sealing ring because leaking powder, being adapted at applying in the outer pressure sealing device of all specification banburies.
Background technology
Closed refining glue (moulding) machine is called for short banbury, and it is the visual plant of rubber plastic processing.Be mainly used in the mixing of rubber or plastics and compounding ingredient, also can be used for plasticating of rubber or plastics.Before banbury comes out, these process all complete on open two rollers refining glue (moulding) machine (abbreviation mill).The workman that the action need of mill is skilled, labour intensity is large and very dangerous, and working condition is very poor, dust from flying, and environmental pollution is serious, and production efficiency is low, unstable product quality.Use banbury can effectively overcome above-mentioned shortcoming, therefore obtain applying more and more widely in rubber plastic product industry.
Banbury is when carrying out milling work, and because banbury is airtight, therefore its loss of material is than mill much less, also greatly alleviates the pollution of environment.But there is annular gap between rotor journal and banburying chamber's sidewall endoporus, and have pressure in banburying chamber in mixing process, in order to prevent material from spilling, sealing device must be adopted herein.
The structural shape of sealing device is a lot, and what current domestic application was maximum is external pressure face seals.The external pressure face seals that tradition is seen is when banbury works, because banburying secret is under rotor is in strong stress all the time, produce the motion state of flexing distortion therefrom, when rotating to making rotor, the swing that the rotary packing ring of its both ends of the surface connection produces around axis runs, and then produce gap of fitting during laminating with stationary seal ring, rubber and powder then enter the annular gap between rotor journal and banburying chamber's sidewall endoporus by this gap, produce leakage therefrom, this laminating gap is exactly produce the main cause of leaking.Current banbury both domestic and external is a lot, but no matter uses the sealing device of that pattern, and more or less all there is the phenomenon of leaking powder in various degree, it has almost become a kind of insoluble common fault that can not circuitously get over of banbury; Make the leakage of banbury sealing device, become the technical problem that modern banbury is badly in need of further Improvement and perfection, this is problem to be solved by this invention just also.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, there is provided a kind of structure simple, easy and simple to handle, easy to use, be convenient to the banbury external-compression type sealing device changing sealing ring and maintenance, under identical condition of work, effectively can improve the sealing effectiveness of sealing device and the service life of sealing ring, can stop or greatly reduce the leakage of sealing device, thus significantly reduce the pollution to surrounding enviroment.
The technical solution used in the present invention is as follows:
Banbury external-compression type sealing device of the present invention, comprise seal receptacle and armature spindle, described seal receptacle is fixed on banbury sidewall, described armature spindle is through the hole of seal receptacle, be provided with in the hole of described seal receptacle and be placed on sealing ring on armature spindle and flexible sealing ring, described flexible sealing ring and sealing ring fit, and described sealing ring and rotor end-face fit; On described armature spindle, cover has the pusher platen be butted on flexible sealing ring, and described pusher platen under external force, promotes sealing ring and is affixed on formative dynamics sealing on rotor end-face all the time.
Owing to have employed said structure, when the sealing ring of rotor end-face laminating makes its banbury work, the sealing ring of fitting with rotor end-face is in nonstatic state, dynamic adhesion sealing is carried out, to compensate the rotary packing ring (sealing ring) the eliminating above-mentioned rotor end-face laminating clearance issues that produce easy in stationary seal ring (flexible sealing ring) when making to swing with rotor end-face between sealing ring.Simultaneously, after sealing ring, namely nonmetallic flexible material (flexible sealing ring) wear-resisting is together increased in the passage between rotor journal and banburying chamber's sidewall endoporus, under making its promotion at pusher platen (by external pressure thrust), fill up cannelure on passage and armature spindle and seal receptacle, and push sealing ring to, fit tightly rotor end-face to make sealing ring.Adopt the sealing device that this is dual, and then make rotor when rotated, reach effective sealing.The present invention adopts distinguished sealing device, with the key point addressed the leakage concern.Banbury external-compression type sealing device of the present invention, structure is simple, easy and simple to handle, easy to use, be convenient to change sealing ring and maintenance, under identical condition of work, effectively can improve the sealing effectiveness of sealing device and the service life of sealing ring, can stop or greatly reduce the leakage of sealing device, thus significantly reduce the pollution to surrounding enviroment.
Banbury external-compression type sealing device of the present invention, the outer wall of described rotor and the inwall of seal receptacle are equipped with cannelure, the inner and outer wall of described flexible sealing ring can fill up cannelure, makes the inwall of the outer wall of the inwall of flexible sealing ring and rotor, the outer wall of flexible sealing ring and seal receptacle all form labyrinth seal structure.
Owing to have employed said structure, flexible sealing ring, under the promotion (by external pressure thrust) of pusher platen, fills up the cannelure on the inwall of seal receptacle and armature spindle, and pushes sealing ring to, fit tightly rotor end-face to make sealing ring; All labyrinth seal structure is formed between the outer wall of the inwall of flexible sealing ring and the outer wall of rotor, flexible sealing ring and the inwall of seal receptacle, this kind of sealing means, make rotor when rotated, reach effective sealing, can stop or greatly reduce the leakage of sealing device, thus significantly reduce the pollution to surrounding enviroment.
Banbury external-compression type sealing device of the present invention, the outer wall of the outer wall of described sealing ring and the inwall of seal receptacle and flexible sealing ring and the inwall of seal receptacle form static seal structure respectively.
Owing to have employed said structure, the static seal structure that sealing ring, flexible sealing ring are formed with the inwall of seal receptacle respectively, can effectively guarantee its sealing effectiveness, can stop or greatly reduce the leakage of sealing device, thus significantly reduce the pollution to surrounding enviroment.
Banbury external-compression type sealing device of the present invention, described seal receptacle is secured by bolts in the hole of banbury sidewall.
Owing to have employed said structure, seal receptacle is fixed by bolts in the hole of banburying chamber's sidewall, can dismantle, and is convenient to maintenance.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, banbury external-compression type sealing device of the present invention, structure is simple, easy and simple to handle, easy to use, is convenient to change sealing ring and maintenance, is applicable to applying.
