Abstract
The utility model discloses a connecting structure of a steam inlet on a steam jacket of an oxidation kettle. The connecting structure comprises a steam conduit arranged in the steam jacket and a long flange with a steam channel, wherein the bottom of the long flange extends to the inner wall surface of the steam jacket. A connecting block is arranged on the inner wall surface of the steam jacket. The connecting block is internally provided with a through connection steam channel which is communicated with the steam channel in the long flange. The through connection steam channel is arranged vertical to the steam conduit. The upper end opening of the steam conduit is connected with the connecting block through a straight taper pipe thread and is communicated with the through connection steam channel. The connecting structure of the steam inlet on the steam jacket of the oxidation kettle provided by the utility model has the advantages that the connecting structure of the steam inlet on the steam jacket of the oxidation kettle is very convenient to process, the processing strength is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to the stills for air blowing structure in p-phthalic acid's production technology, relates in particular to the syndeton of steam inlet on the steam jacket of the outside of materail tube on the stills for air blowing in p-phthalic acid's production technology.
Background technology
The p-phthalic acid is called for short PTA, is mainly used in the production polyester.Because polyester is applied to fields such as weaving, cinefilm, coating, paint, polyester plastics more and more widely, so p-phthalic acid's demand is also increasing.The fine terephthalic acid production technical process can be divided into oxidation unit and hydrofinishing unit, and stills for air blowing play very important effect in oxidation unit.Temperature of charge in the stills for air blowing in the materail tube generally need remain on more than 200 ℃; Therefore be provided with the steam jacket that is used to be incubated usually in the outside of materail tube; As shown in Figure 1; The syndeton of steam inlet is on the stills for air blowing steam jacket that uses at present: the bottom of the regular way of carrying vapour passage 31 blue 3 directly extend in the inner chamber of steam jacket 1, is provided with steam lead 2 in the steam jacket, because the restriction of assembly technology and assembly space; 60 ° of angles of mouth of pipe inclination, upper end of steam lead 2 are connected through oblique cone gas thread 4 with the bottom of regular way blue 3, and steam lead 2 is connected with steam channel 31.High-temperature steam enters into steam lead 2 from steam channel 31, enters into steam jacket 1 through steam lead 2 again, thereby makes steam jacket 1 play the effect of being incubated for the material in the materail tube.The long and end sealing of the length of regular way blue 3 in the said structure, so the processing of steam channel 31 is very inconvenient in the regular way blue 3, and because steam lead 2 tilts, it is processed also with the oblique cone gas thread between the regular way blue 3 wastes time and energy, extremely difficult processing.
The utility model content
The problem that the utility model need solve be: a kind of processing syndeton of steam inlet on the stills for air blowing steam jacket very easily is provided.
For addressing the above problem; The technical scheme that the utility model adopts is: the syndeton of steam inlet on the stills for air blowing steam jacket; Comprise: be arranged on the steam lead in the steam jacket, and to extend into the regular way of the carrying vapour passage on the steam jacket internal face blue in the bottom, the internal face of steam jacket is provided with contiguous block; Be provided with the switching steam channel in the contiguous block; Described switching steam channel is connected with steam channel in the regular way orchid, switching steam channel and the perpendicular setting of steam lead, and the port of described steam lead is connected through straight taper pipe thread with contiguous block and the port of steam lead is connected with the steam channel of transferring.
Further, the syndeton of steam inlet on the aforesaid stills for air blowing steam jacket, wherein, the switching steam channel in the described contiguous block is perpendicular to the inwall of steam jacket.
The utility model has the advantages that: process very conveniently, reduced processing intensity, improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the syndeton of steam inlet on the stills for air blowing steam jacket described in the background technology.
Fig. 2 is the structural representation of the syndeton of steam inlet on the described stills for air blowing steam jacket of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
As shown in Figure 2; The syndeton of steam inlet on the stills for air blowing steam jacket; Comprise: be arranged on the steam lead 2 in the steam jacket 1, and to extend into the regular way of the carrying vapour passage 31 on steam jacket 1 internal face blue 3 in the bottom, the internal face of steam jacket 1 is provided with contiguous block 4; Be provided with switching steam channel 31 in the contiguous block 4; Steam channel 31 in described switching steam channel 41 and the regular way blue 3 is connected, switching steam channel 41 and steam lead 2 perpendicular settings, and the port of described steam lead 2 is connected through straight taper pipe thread 5 with contiguous block 4 and the port of steam lead 2 is connected with the steam channel 41 of transferring.In the present embodiment, the switching steam channel 41 in the described contiguous block 4 is perpendicular to the inwall of steam jacket 3.
The advantage of the syndeton of steam inlet is on the stills for air blowing steam jacket in sum: owing to be provided with the contiguous block 4 that is connected usefulness with steam lead 2 in the bottom of regular way blue 3; Thereby whole input steam channel is transformed into the two-part combining structure; Not only make the corresponding shortening of length of regular way blue 3; And during the steam channel 31 in the processing regular way blue 3, can be very easy to the processing of steam channels 31 in the regular way blue 3 in the operation of the two ends of regular way blue 3; In addition because the switching steam channel 41 in the contiguous block 4 is perpendicular with steam lead 2; Contiguous block 4 can adopt straight taper pipe thread 5 to be connected with steam lead 2; And straight taper pipe thread 5 adds and will make things convenient for much easier than the oblique cone gas thread man-hour, reduced processing intensity, improved production efficiency.
Claims (2)
1. the syndeton of steam inlet on the stills for air blowing steam jacket; Comprise: be arranged on the steam lead in the steam jacket; And the bottom extend into the regular way orchid of the carrying vapour passage on the steam jacket internal face; It is characterized in that: the internal face of steam jacket is provided with contiguous block, is provided with the switching steam channel in the contiguous block, and described switching steam channel is connected with steam channel in the regular way orchid; Switching steam channel and the perpendicular setting of steam lead, and the port of described steam lead is connected through straight taper pipe thread with contiguous block and the port of steam lead is connected with the switching steam channel.
2. the syndeton of steam inlet on the stills for air blowing steam jacket according to claim 1 is characterized in that: the switching steam channel in the described contiguous block is perpendicular to the inwall of steam jacket.
