Door, for stretching in the big syphon of annular-pipe reactor, carries out the big of automatic polishing to the inner wall surface of the big syphon of annular-pipe reactor
Diameter elbow internal wall automatic polishing device, is particularly suited for Loop Reactor for Polypropylene or polyethylene loop in petrochemical industry
The elbow internal wall automatic polishing device that reactor is used.
Background technology
Annular-pipe reactor is polypropylene or main production equipments, polypropylene or the polyethylene of polypropylene special plastic PP Pipe Compound
Plastic raw materialss purposes is extremely extensive, is widely used in the articles for daily use such as household electrical appliances, furniture, toy, and the industry such as automobile, aircraft zero
On part.Before nineteen ninety-five, annular-pipe reactor is both needed to external import, and at present, this equipment has been achieved with domesticizing, equipment Market pole
It is wide.
Common annular-pipe reactor, including some straight connectors being arranged according to production capacity size and connect straight connector
Big elbow, straight connector includes inner and outer tubes, and the end of big elbow is sequentially connected in series with the end of inner tube, is linked to be for reacting
The connection runner of the conveying of material and reaction, annular-pipe reactor is vertical equipment, equipment -40 DEG C of low temperature and 150 DEG C of high temperature,
Pressure and long-term operation under vaccum working condition in 3.5mpa, inner tube medium is propylene slip, inflammable and explosive.Because propylene slip is in ring
Carry out in pipe being constantly in flow regime during polyreaction, thus higher to surface roughness requirements, produced with preventing material from gluing wall
Implosion, the design roughness of endless tube inwall needs satisfaction≤ra2.5 μm.
Applicant proposed " a kind of annular-pipe reactor inner tube automatic polishing device ", its Granted publication on April 1st, 2012
Day is on 2 19th, 2014, Patent No. zl 201210095652.9, and this automatic polishing device solve only annular-pipe reactor
Interior pipe internal surface automatic polishing problem.
However, for the big syphon of annular-pipe reactor, because big syphon is a three-dimensional space structure, its letter
As shown in figure 1, the specification of current bend pipe has two kinds, a kind of bend pipe specification is figureφ609.6 × 16mm, centre-to-centre spacing be a4200 ±
5mm, highly for h2333 ± 5mm, gross weight about 2.5t;Another kind of bend pipe specification isφ711×21mm.In the industry, for ensureing polishing
Effect, needs repeatedly to be polished, and inspection before warehouse-in needs just polishing, balance manufacturing process to need rough polishing, meet apparatus and process
Requirement needs finishing polish, and all the time, finishing method that one's own profession adopts in the industry is to be crawled into by operator's hand polishing machine of lying down
Manually polished in big syphon, be there is following defect: (1) high labor intensive;(2) due in big syphon narrow space so that
Inconvenient operation, inefficiency, and illuminate difficult dangerous;(3) dirt that becomes rusty in big syphon flies upward, working environment is unhygienic;
(4) in polishing process, the arm of operator is vibrated easily tired, if holding unstable buffing machine to be susceptible to injury accident, and
Manual effort inequality will lead to quality of finish not good, and needs are repeated multiple times could to meet requirement.

Wheel 9,10,11 is arranged in pairs and described elastic compression wheel 12 is arranged at the described rotation diameter of a circle polishing planetary gear 9,10,11
Symmetric position.In the technical program, three buff wheel planetary gears respectively need the pressuring action of a gum elastic contact roller to make throwing
Light planetary gear 9,10,11 is close to the inwall of bend pipe, 9,10,11 and gum elastic contact roller composition one of a polishing planetary gear
Right, polish planetary gear 9,10,11 every a pair and gum elastic wheel is symmetrically installed on turning-circle diameter.Active force equilibrium and
Active force is equivalent, it is to avoid kinetic energy loss, can be good at vibrationproof so that buffing machine more stably works simultaneously, it is to avoid mechanism
Vibrate the quality of finish causing uneven.
Specifically, the top of described walking vehicle body 3 is provided with and tightens spring for compress described passive walking wheel 7.Its
Effect is to make four passive walking wheels 7 of walking vehicle body 3 bottom setting and can produce between smooth surface in the bend pipe of polishing
The enough frictional force of life, it is to avoid walking is skidded.This kind of design structure is simple, ingenious, in addition, this tightens spring can pass through simply
Adjustment bolt adjusting its length, thus adapting to the different deviation of bend pipe internal diameter.
Specifically, described revoliving arm 18 includes the first revolution body of rod being socketed and the second revolution body of rod.Using loop bar structure
Revoliving arm 18, its length can be adjusted and position, to adapt to the change of the bending radius of major diameter bend pipe 1.
Specifically, the rear end of described walking vehicle body 3 is provided with the coating for finishing polish surface is coated with protective layer
Device.It is the needs of liquid film or adipose membrane according to protective layer, coating is slightly distinguished, and coating unit can be selected to be to drag the formula of sweeping or sprinkling
Formula structure.
Specifically, described walking vehicle body 3 is provided with cool air hose, and the air port of described cool air hose is towards described polishing rotating mechanism
4.It is specially the polisher head towards polishing rotating mechanism 4 and driving belt, for a long time in narrow space-closed mechanical polishing process,
The motor feels hot and the frictional heating of buff wheel make quickly internal the temperature rises, during polishing, dust flies upward and can fall in driving belt, institute
Purged with cool air hose to be passed through and cool down, create suitable operating conditions.
Specifically, described walking vehicle body 3 is provided with quality of finish remote observation system.This remote observation system includes video
Harvester and display device, wherein video acquisition device can be endoscope or camera video system, and display device is aobvious
Display screen, operation or quality testing personnel can be by the display screen monitor in real time qualities of finish outside major diameter bend pipe 1, without handle
Bend pipe with large diameter detection withdrawn from by polishing rotating mechanism 4, crawls into detection in major diameter bend pipe 1 also without personnel simultaneously.
Specifically, described walking vehicle body 3 is provided with illuminator.It is easy to operation or quality testing personnel in major diameter bend pipe
Naked eyes during 1 entrance point polishing are it may determine that effect is so that timely adjusting parameter.
