Abstract
The utility model provides a kind of electric machine rotor blueing furnace, including furnace body and air valve；Fire door is installed on the furnace body, is connected between the air valve and furnace body by tracheae, the lower half of the tracheae connection furnace body.The airintake direction of high-temperature water vapor is from top to bottom changed to from the bottom to top by the utility model, keeps high-temperature water vapor air-flow more uniform, improves the consistency of dielectric oxide film, insulation effect is more preferably.Further, since the height of air valve is far smaller than the height of furnace body, and the bottom of the two is often positioned in sustained height, while changing the airintake direction of high-temperature water vapor, greatly reduces the length of tracheae, improves the service life of tracheae, and installation and replacement are more convenient.
Description
Technical field
The utility model relates to engineering device technique fields of turning blue, and in particular to a kind of electric machine rotor blueing furnace.
Background technique
Blueing furnace is generally used for electric machine rotor surface insulation and antirust treatment, and workpiece is formed in metal surface after processing
Layer oxide film has very fine and close and very thin structure, because oxidation film is formed on the surface of metal itself, so having non-
Often high adhesive force and insulation performance.
The steam inlet direction of existing blueing furnace is passed through furnace interior by the top of blueing furnace, to the workpiece of furnace interior into
Capable processing of turning blue.But since the temperature of high-temperature water vapor is higher, its density is relatively small, therefore is led to by the top of blueing furnace
After crossing furnace interior, hot steam is easily collected on the top of furnace body, causes to turn blue ineffective.
Utility model content
The technical problem to be solved by the utility model is to the steam inlet directions of existing blueing furnace by the upper of blueing furnace
Portion is passed through furnace interior, and hot steam is easily gathered in upper of furnace body, leads to ineffective problem of turning blue.
The utility model solves above-mentioned technical problem using following technical scheme:
A kind of electric machine rotor blueing furnace, including furnace body and air valve；Fire door, the air valve and furnace are installed on the furnace body
It is connected between body by tracheae, the lower half of the tracheae connection furnace body.
Further, the inside of the furnace body is equipped with interior furnace, and the tracheae is connected to the lower half of interior furnace.
Further, the tracheae is mounted on the bottom sides of interior furnace.
Further, the tracheae is mounted on the bottom of interior furnace.
Further, fire door lifting controller is installed on the fire door.
The utility model has the following beneficial effects:
The airintake direction of high-temperature water vapor is from top to bottom changed to from the bottom to top by the utility model, makes high-temperature water vapor air-flow
It is more uniform, the consistency of dielectric oxide film is improved, insulation effect is more preferably.Further, since the height of air valve is far smaller than furnace body
Height, and the bottom of the two is often positioned in sustained height, while changing the airintake direction of high-temperature water vapor, greatly reduces
The length of tracheae improves the service life of tracheae, and installation and replacement are more convenient.
Detailed description of the invention
Fig. 1 is the structure chart of electric machine rotor blueing furnace in the utility model embodiment.
Specific embodiment
In order to the utility model structure feature and it is reached the effect of have a better understanding and awareness, to compared with
Good examples and drawings cooperate detailed description, are described as follows:
A kind of electric machine rotor blueing furnace, as shown in Figure 1, including furnace body 1 and air valve 2；
Fire door 11 is installed at the top of the furnace body 1, fire door lifting controller 12 is installed, for controlling fire door on fire door 11
11 lifting.The inside of furnace body 1 is equipped with interior furnace 13, and interior furnace 13 is cylindrical shape, and electric machine rotor is placed in interior furnace 13, and (figure is not
Show).
The air valve 2 is used to control the opening and closing of steam gas source, and air valve 2 is set to 1 side of furnace body, passes through between furnace body 1
Tracheae 3 is connected to.Tracheae 3 is connected to the lower half of interior furnace 13, it is preferable that tracheae 3 is connected to bottom or the bottom sides of interior furnace 13.
In the present embodiment, tracheae 3 is connected to the bottom sides of interior furnace 13.
During turning blue, high-temperature steam is entered the bottom of interior furnace 13 by tracheae 3, and the density of high-temperature steam is smaller, by interior furnace
13 bottom is gradually flowed above inside furnace 13, to form dielectric oxide film on the surface of rotor.By airintake direction by upper
It is changed under from the bottom to top, keeps high-temperature water vapor air-flow more uniform, improve the consistency of dielectric oxide film, insulation effect is more
It is good.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only the principles of the present invention, the utility model also has respectively on the premise of not departing from the spirit and scope of the utility model
Kind changes and improvements, these changes and improvements are both fallen in the range of claimed invention.The requires of the utility model
Protection scope defined by appended claims and its equivalent.
