In addition, still easily installation, the adjustment of being convenient for.
Description
Technical field
The utility model belongs to chemical equipment technical field, is specifically related to a kind of swinging multi-heating-pipe pyrolysis kiln tube bank self-supporting mechanism.
Background technology
At present, rotary pipe type drying machine and rotary pipe type pyrolysis kiln all have employed and organize heating tube bundle more domestic and international application widely.Generally speaking, the caliber of heating tube is at φ 30 ~ φ 300mm, and the longest 60m that reaches of length, multi units tube bundle is uniformly distributed in rotating cylinder.For avoiding heating tube to occur bending and deformation along its length, the support of some should be arranged in their length direction.Mostly existing general method for supporting is to adopt bearing that 4 ~ 20 pipes are formed tube bank, and fixes in groups, and bearing is welded on cylinder inboard wall, or by bolt-connection on inwall.Usually along the length direction of pipe being furnished with multiple such bearing.This method has connection good rigidly, comparatively firmly advantage.But its shortcoming needs to be welded on inside pipe wall, and pad is many, construction inconvenience, and bearing and cylinder inboard wall temperature distortion amount different, thus cylindrical shell can produce local contraction phenomenon, namely has a large amount of thermal stress.To the pyrolysis kiln adopting double-layer thin wall inner core, such fixing means easily causes inner barrel stressed comparatively large, easily produces moderate finite deformation and causes cracking damage.In addition owing to being be fixedly connected with, be not easy to mobile adjustment.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of swinging multi-heating-pipe pyrolysis kiln to restrain self-supporting mechanism, its major advantage is: heating tube bracing frame is without the need to together with barrel soldering, thus the force-bearing situation of cylindrical shell is substantially improved, improve the security that equipment runs, also contribute to reducing cylindrical shell thickness, weight reduction, reduces costs.In addition, be also easy to install, be convenient to adjustment.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of swinging multi-heating-pipe pyrolysis kiln self-supporting mechanism, comprise multiple supporting components of the interval predeterminable range arranged along its length in cylindrical shell 7, each supporting component comprise be distributed on same cross section and uniform 3 ~ 8 for supporting the fan-shaped support plate 4 of heating tube bundle 3, fan-shaped support plate 4 is welded with the ring pipe 2 supporting heating tube bundle 3, the inner of the fan-shaped support plate 4 in same cross section is rigidly connected by connecting rod 6, forms stable self-supporting mechanism.
The gap of 3 ~ 8mm is kept between the outer rim of described fan-shaped support plate 4 and cylindrical shell 7 inwall, the axial and circumferential that cylindrical shell 7 inwall is positioned at fan-shaped support plate 4 weld axial stop 1 and circumferential block 5 respectively, move with the axial and circumferential limiting fan-shaped support plate 4, axial stop 1 and circumferential block 5 bear certain external force simultaneously.
Described multiple supporting component is 2 ~ 15, and for ease of arranging fan-shaped support plate 4, the heating tube bundle 3 of adjacent supports modular support along the circumferential direction staggers predetermined angle, to form the supporting component of intersection.
The fan-shaped support plate 4 of described adjacent supports assembly misplaces layout vertically.
Compared to the prior art comparatively, the utility model possesses following advantage:
1, because heating tube bundle bracing frame discord cylinder inner surface welds together, therefore substantially improve the force-bearing situation of cylindrical shell, effectively reduce static stress and distortion, improve the safety and reliability that equipment runs.
2, the improvement of cylindrical shell force-bearing situation, makes to adopt less cylindrical shell thickness, alleviates weight, reduce cost.
3, movable supporting component makes the install and adjust of restraining all become easy and convenient.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 4 shows, a kind of swinging multi-heating-pipe of the utility model pyrolysis kiln self-supporting mechanism, comprise multiple supporting components of the interval predeterminable range arranged along its length in cylindrical shell 7, each supporting component comprise be distributed on same cross section and uniform 3 ~ 8 for supporting the fan-shaped support plate 4 of heating tube bundle 3, fan-shaped support plate 4 is welded with the ring pipe 2 supporting heating tube bundle 3, the inner of the fan-shaped support plate 4 in same cross section is rigidly connected by connecting rod 6, forms stable self-supporting mechanism.
As preferred embodiment of the present utility model, keep the gap of 3 ~ 8mm between the outer rim of described fan-shaped support plate 4 and cylindrical shell 7 inwall, like this, be not only convenient to the mounting and adjusting of heating tube bundle, but also heating tube bundle amount of deflection in the longitudinal direction and distortion can be controlled.The axial and circumferential that cylindrical shell 7 inwall is positioned at fan-shaped support plate 4 weld axial stop 1 and circumferential block 5 respectively, move with the axial and circumferential limiting fan-shaped support plate 4, keep the relative position of fan-shaped support plate 4 in cylindrical shell 7 constant.Axial stop 1 and circumferential block 5 bear certain external force simultaneously.
As preferred embodiment of the present utility model, described multiple supporting component is 2 ~ 15, to keep heating tube along total length direction having stronger bending rigidity and less sag; For ease of arranging fan-shaped support plate 4, the heating tube bundle 3 of adjacent supports modular support along the circumferential direction staggers predetermined angle, to form the supporting component of intersection, and takes into account and can support all heating tubes.
As shown in Figure 3, as preferred embodiment of the present utility model, the fan-shaped support plate 4 of described adjacent supports assembly misplaces layout vertically, like this, is unlikely to affect the movement that heating object material is gone up along its length.
For ease of carrying out maintain and replace, the connecting rod between each secter pat can be with bolts, certainly also can adopt welding.
Detailed description of the invention of the present utility model is not confined to aforesaid embodiment, on the contrary, within the scope of the utility model that claim limits, on the basis not changing utility model principle, can have the implementation method of multiple change.
