Abstract
The utility model discloses a cooling system for a fan bearing of a nitrogen furnace, which consists of an annular cavity, a gas inlet pipe and a gas outlet pipe, wherein the annular cavity is arranged on the periphery of a main shaft; the annular cavity is arranged at the outer side of the bearing and is connected with the bearing; the gas inlet pipe and the annular cavity are mutually communicated with the gas outlet pipe; nitrogen is introduced into the annular cavity by the nitrogen furnace along the gas inlet pipe; and the nitrogen is discharged from the gas outlet pipe after blowdown cooling is performed on the main shaft. The annular cavity is arranged at a position on the periphery of the main shaft, which is near the bearing, and the nitrogen required by the furnace per se is introduced into the annular cavity to cool the bearing, and thereby, a cooling effect on the bearing is enhanced, and the goals that special gas supply cooling is not needed, water cooling leakage is avoided, and the cooling effect is good are achieved.
Description
Technical field
The utility model relates to High Temperature Furnaces blower fan field, is specifically related to a kind of bearing cooling system.
Background technique
In the high-temperature blower application; Along with improving constantly of smoke exhaust fan flue-gas temperature, to having higher requirement the working life of blower fan, draught fan impeller turns round under high-temperature gas and can produce heat; Heat passes to bearing through axle; And bearing itself can produce heat under at a high speed, the heat of bearing superposes under these two kinds of states, and reduced the working life of bearing greatly.
At present; Stove to the type of cooling of fan bearing require increasingly high; Traditional cooling generally all is to adopt air-cooled and two kinds of types of cooling of water-cooled; But adopt the type of cooling of water-cooled that the danger of leaking is arranged, so some stove does not allow use water-cooled, and the air-cooled type of cooling comparatively speaking effect want nearly.
Therefore, fan bearing is better cooled off, and can avoid the danger of leaking, can be described as the task of top priority of blower fan industry.
The model utility content
For solving the problems of the technologies described above, we have proposed a kind of air feed specially, avoid leaking and the nitrogen furnace fan bearing cooling system of good cooling results.
For achieving the above object, the technological scheme of the utility model is following:
A kind of nitrogen furnace fan bearing cooling system is formed by being located at main shaft peripheral an annular housing, suction tude and steam outlet pipe; Said annular housing is located at the bearing outside, and is connected with said bearing; Said suction tude, said annular housing and said steam outlet pipe interconnect; Said nitrogen furnace feeds said annular housing with nitrogen along said suction tude, to discharging from said steam outlet pipe after the said main shaft blowing cooling again.
Preferably, said suction tude and said steam outlet pipe are divided into said main shaft both sides.
Pass through technique scheme; The utility model through main shaft peripheral establish an annular housing near the bearing place; The nitrogen that adopts stove itself to need feeds annular housing and comes cooling bearing; Strengthen the cooling effect of bearing, thereby reached specially air feed cooling, avoid water cooling to leak and the purpose of good cooling results.

Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technological scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of nitrogen furnace fan bearing cooling system, its working principle be main shaft peripheral establish an annular housing near the bearing place, the nitrogen feeding annular housing that adopts stove itself to need comes cooling bearing, has strengthened the cooling effect of bearing.
Below in conjunction with embodiment and embodiment the utility model is done further detailed explanation.
Embodiment.
Like Fig. 1, shown in Figure 2, a kind of nitrogen furnace fan bearing cooling system is formed by being located at main shaft 1 peripheral an annular housing 2, suction tude 3 and steam outlet pipe 4; Said annular housing 2 is located at bearing 5 outsides, and is connected with said bearing 5; Said suction tude 3, said annular housing 2 interconnect with said steam outlet pipe 4; Said nitrogen furnace feeds said annular housing 2 with nitrogen along said suction tude 3, to discharging from said steam outlet pipe 4 after the said main shaft 1 blowing cooling again.Wherein, said suction tude 3 is divided into said main shaft 1 both sides with said steam outlet pipe 4.
The working principle and the working procedure of a kind of nitrogen furnace fan bearing cooling system of the utility model are: as depicted in figs. 1 and 2; In the nitrogen furnace working procedure, draught fan impeller turns round under high-temperature gas and can produce heat, and heat passes to bearing 5 through main shaft 1; And bearing 5 itself can produce heat under at a high speed; The heat of bearing 5 superposes under these two kinds of states, therefore, cool to bearing 5.Because nitrogen furnace itself needs in stove, to feed nitrogen; Just establish an arm on the nitrogen pipeline before nitrogen feeds and link suction tude 3; Make the annular housing 2 of the nitrogen of low temperature from suction tude 3 entering bearings 5 outsides; And then discharge from steam outlet pipe 4, so just take away bearing 5 place's heats, thereby reach the purpose of the bearing 5 of cooling.
Pass through technique scheme; The utility model through main shaft 1 peripheral establish an annular housing 2 near bearing 5 places; The nitrogen that adopts stove itself to need feeds annular housing 2 and comes cooling bearing 5; Strengthen the cooling effect of bearing 5, thereby reached air feed cooling specially, avoid water cooling to leak and the purpose of good cooling results.
To disclosed a kind of nitrogen furnace fan bearing cooling system embodiment's above-mentioned explanation, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiments shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
