Description
Technical field
This utility model relates to rotary air heater technical field, specifically a kind of simple and easy Rotatable mechanism.
Background technology
Boiler Air Heater's is the heat transmission equipment that preheating enters air preheater cold air, large-sized station boiler divides First air steam air heater and secondary wind steam air heater, its structure is identical with principle, effect is the air themperature improving and entering air preheater, prevent the cold end corrosion of air preheater low-temperature zone, unless in cold winter, steam air heater makes to put into operation within the most of the time of 1 year, even if steam air heater does not put into operation, existence due to steam air heater heat-transfer surface, resistance can be there is in air channel, after long-time stoppage in transit steam air heater corrosion and adhering dust, resistance increases, dirty stifled serious, pressure fan power consumption is caused to increase, machine set of long-period high-efficiency operation is constituted a threat to.Some rotary air heaters, when steam air heater is stopped transport, first all take apart the bolt of the flange on steam pipe and heat exchanger fin house steward Yu anti-flange, being rotated further by rotation hand wheel, the heat exchanger fin of steam air heater does 90 °-0 ° rotation, makes steam air heater heat exchanger fin parallel with air channel, thus reducing windage, it is achieved Fan Energy-saving；Steam air heater heat exchanger fin can be converted into and the angle of air channel level by heat exchanger fin within 1 year most of the time, makes foreign material take away with the wind, it is to avoid the blocking to steam air heater；When steam air heater puts into operation, by steam air heater heat exchanger fin rotate to air channel vertical angle.
Currently in order to it is easy to operate, some rotary air heaters are generally adopted swivel joint and realize rotating, owing to loine pressure is big, temperature is high so that existing rotary joint structure is complicated, price is high, and revolving force is big, for smooth rotation, often want during rotation first housing pin to be loosened, screw again after rotation, airtight and watertight padding is damaged by this processing ease, and impact seals, and causes the generation of gas leakage drainage.
Utility model content
The utility model proposes a kind of simple and easy Rotatable mechanism.
The technical solution of the utility model is achieved in that a kind of simple and easy Rotatable mechanism, it is characterized in that: include the mounting flange sheet that fixed cover is located on steam pipework lateral surface, the loose flange sheet being flexibly connected with mounting flange sheet, and fixed cover is located at the seal connector on heat exchanger fin house steward's lateral surface, described loose flange sheet is movably set on the lateral surface of seal connector；Seal connector is a circle back-up ring near one end of steam pipework, and seal connector is provided with the annular groove of lopping on the end face of steam pipework, the end face that steam pipework is relative with seal connector is provided with the lopping with annular groove corresponding matching protruding.
As preferred technical scheme, described mounting flange sheet and loose flange sheet are correspondingly arranged multipair bolt hole, in bolt hole, are flexibly connected bolt.
As preferred technical scheme, described seal connector arranges operation handwheel away from one end of steam pipework.
As the connection of preferred technical scheme, described mounting flange sheet and steam pipework, seal connector is sealing and welds with the connection of heat exchanger fin house steward.
As preferred technical scheme, in described annular groove, sealing ring is set.
As preferred technical scheme, described sealing ring is graphite metal wound gasket.
Owing to have employed technique scheme, this utility model has beneficial effect highlighted below:
1, simple in construction, easy to use, can be used as ring flange and use, it is achieved steam pipework and the connection of heat exchanger fin house steward, baroque swivel joint can be replaced again to use, it is achieved heat exchanger fin house steward rotates freely, and cost is low, it is simple to promotion and application.
2, when needs conversion between steam air heater runs and be out of service, only need to by the bolt looseness between mounting flange sheet and loose flange sheet, rotating operation handwheel, the rotation of heat exchanger fin house steward can be realized, it is not necessary to pull down bolt, easy to operate, time saving and energy saving.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is this utility model structural representation.
In figure: 1-steam pipework；2-mounting flange sheet；3-loose flange sheet；4-heat exchanger fin house steward；5-seal connector；6-bolt hole；7-operates handwheel；8-annular groove；9-is protruding；10-steam air heater shell.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, this utility model includes the mounting flange sheet 2 that fixed cover is located on steam pipework 1 lateral surface, the loose flange sheet 3 being flexibly connected with mounting flange sheet 2, and fixed cover is located at the seal connector 5 on heat exchanger fin house steward 4 lateral surface, described loose flange sheet 3 is movably set on the lateral surface of seal connector 5.Mounting flange sheet 2 and loose flange sheet 3 are correspondingly arranged multipair bolt hole 6, are flexibly connected bolt in bolt hole 6, by bolt, both are linked together.Described seal connector 5 is arranged on heat exchanger fin house steward 4 one end near steam pipework 1, heat exchanger fin house steward 4 is rotatably connected on steam air heater shell 10 away from one end of steam pipework 1, seal connector 5 is a circle back-up ring near one end of steam pipework 1, loose flange sheet 3 is played position-limiting action by the existence of back-up ring, described seal connector 5 arranges operation handwheel 7 away from one end of steam pipework 1, by rotation process handwheel 7, the rotation of seal connector 5 can be realized, i.e. the rotation of heat exchanger fin house steward 4.
The connection of mounting flange sheet 2 and steam pipework 1, seal connector 5 is sealing and welds with the connection of heat exchanger fin house steward 4.
