Abstract
The utility model discloses a steam swivel joint for a polypropylene film production line, which mainly aims to solve the problem that a fault is caused to the swivel joint because a swivel joint inner pipe rubs with the tail of a shell of the swivel joint and a graphite annulus. The joint comprises a swivel joint inner pipe and a swivel joint outer pipe, wherein the outer edges of four wings of the swivel joint inner pipe are provided with external threads; the inner wall of the swivel joint outer pipe is provided with internal threads matched with the external threads; and the swivel joint inner pipe and the swivel joint outer pipe are fixedly connected through the internal threads and the external threads. In the steam swivel joint, the fluctuation caused to the temperature of a roller because of the fault of the swivel joint is avoided and the service life of the swivel joint is effectively prolonged, and thereby, the production efficiency and the product quality of the production line are improved.
Description
Affiliated technical field
The utility model structure relates to that BOPP polypropylene film production line is vertical to draw the auxiliary device of equipment Steam Heating transmission system, is specifically related to can prevent in the Steam Heating transmission system steam swivel joint of pipe play in the steam swivel joint.
Background technologyThe Mitsubishi heavy industry produce per year 1.5 ten thousand tons of polypropylene (BOPP) film line by the sheet of preparing burden, extrude, cast, vertical draw, horizontally draw, draw and coiling etc. is partly formed, wherein longitudinal stretching is that the sheet that will extrude heats by a plurality of high-precision metal rollers and under certain velocity gradient sheet material vertically elongated, making polymer molecule carry out machine-direction oriented process, is one of critical process in the film line.The variations in temperature in Qi Ge district is the key factor that influences film stretching orientation, crystallization, and the heat medium of its roller is hydronic overheated saturated vapor, and the roller of running is swivel joints with the parts that static heat medium pipeline connects mutually.Therefore swivel joint is one of equipment the most key in the longitudinal tensile fixture, and the quality of its operation will directly have influence on the on-road efficiency of whole device.If swivel joint generation steam or hot water are revealed, can cause the temperature of heating roller to descend, and then influence film performance, cause product quality to descend.Therefore find that it leaks vapour or leaks and to rush to repair when serious.It is bearing wear or graphite annulus sealing surface wear that common swivel joint breaks down.But behind bearing that more renews and new graphite-seal ring, the swivel joint fault is still frequent to be taken place.Trace it to its cause and be roller axle head inwall and interior pipe connection place serious wear, cooperate pine, swing bigger in causing in the pipe running, rub mutually with swivel joint shell afterbody, graphite annulus, cause shell afterbody, graphite annulus wearing and tearing, produce vibration and steam leakage, as shown in Figure 1, be conical surface shape after the wearing and tearing of pipe junction in roller axle head and the swivel joint.Because roller axle head inwall and interior pipe junction wearing and tearing inconvenience are handled and maintenance time is hurry, therefore take with interior pipe and outer tube mode spot-welded together, as shown in Figure 2.The on-stream play of pipe in temporarily can avoiding, assurance equipment runs well.But fault still takes place, pipe and the on-stream easy generation sealing-off of outer tube weld in reason is.Before the solution that does not find, only take to continue interior pipe and outer tube spot welding are handled, keep production.
The utility model contentThe purpose of the utility model mechanism is to overcome above-mentioned the deficiencies in the prior art, and the steam swivel joint in a kind of polypropylene film production line is provided, and it can prevent the on-stream play of pipe in the swivel joint, reduces wear, and prolongs swivel joint service life.
The utility model is for achieving the above object by the following technical solutions: the steam swivel joint in a kind of polypropylene film production line, comprise pipe and swivel joint outer tube in the swivel joint, the outer rim of four wings of pipe is established external screw thread in the described swivel joint, the swivel joint outer tube wall is provided with the internal thread that cooperates with described external screw thread, and pipe and swivel joint outer tube are affixed by described internal and external screw thread in the described swivel joint.
The outer mouth of pipe of described swivel joint is established jump ring, and described external screw thread is the M48 external screw thread, and described internal thread is the M48 internal thread.
The beneficial effects of the utility model: can prevent on-stream play of pipe and swing in the swivel joint, reduce and rub mutually, reduce the swivel joint fault and take place with housing afterbody and graphite annulus.Having stopped the film sheet influences the performance or the shutdown of product because of heating roller temperature anomaly, thereby has improved the quality percentage and the production efficiency of product.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a pipe connecting structure schematic diagram in roller axle head and the swivel joint;
Fig. 2 is a pipe and outer tube welding schematic diagram in the swivel joint;
Fig. 3 is an interior pipe outer rim reconstruction structure schematic diagram of the present utility model.
Fig. 4 is an outer tube wall reconstruction structure schematic diagram of the present utility model.
Among the figure 1, roller, 2, the roller axle head, 3, the O RunddichtringO, 4, pipe in the swivel joint, 5, the swivel joint outer tube, 6, bearing, 7, floor clip, 8, stripped nut, 9, graphite-seal ring, 10, pad, 11, spring, 12, the swivel joint shell, 13, pad, 14, the wing, 15, jump ring.
The specific embodiment
The utility model comprises pipe 4 and swivel joint outer tube 5 in the swivel joint, the outer rim of four wings 14 of pipe 4 is established external screw thread in the swivel joint, the swivel joint outer tube wall is provided with the internal thread that cooperates with described external screw thread, and pipe and swivel joint outer tube connect by described internal and external screw thread in the swivel joint.The outer mouth of pipe of swivel joint is established jump ring 15, and external screw thread is the M48 external screw thread, and described internal thread is the M48 internal thread.
The utility model installation step: at first, bearing 6 space collars are fixed on the swivel joint outer tube 5, floor clip 7 and circular locking nut 8 are installed.Then, spring 11, pad 10 and carbon seal ring 9 are fixed in swivel joint shell 12 chambeies, swivel joint outer tube 5 is installed in swivel joint shell 12 chambeies together with parts.At last, pipe 4 and swivel joint outer tube 5 in the swivel joint are coupled together, and fixing with jump ring 15, pipe play in preventing.If after swivel joint bearing or the graphite annulus bad seals, only need and to get final product after the damaged part replacing.In normal operation, effectively prevent in the swivel joint pipe and swivel joint outer wall afterbody inwall and graphite annulus sealing friction mutually, reduce wear that prolongation swivel joint service life reaches improve production efficiency and product quality.
Pipe and swivel joint outer tube connect solid and reliablely in the swivel joint of the present utility model, can prevent in the swivel joint pipe play that is in operation effectively, manage in reducing and rub mutually and cause wearing and tearing with swivel joint shell afterbody inwall, graphite annulus.
In actual use by regularly giving bearing lubrication, and behind the status monitoring, pipe and swivel joint outer tube, graphite annulus friction condition mutually do not occur in the swivel joint, and the swivel joint operation normally, produces a desired effect.
