131, the connection trailing edge hole 121 and the outer rim accent 111, the sky of the inner edge accent 131 are provided with the blade 12
Chamber passage, methods described removes the low-melting alloy in the blade 1 using a device, and described device includes an oil drum
2, the bottom of the oil drum 2 is connected with a cooling tank 3 by with valvular pipeline, and the cooling tank 3 is connected with by pipeline
One heater 4 with oil pump, the side wall of the oil drum 2 is provided with mouth spray 21, and the top of the oil drum 2 is provided with liftable
And rotatable mounting disc 5, the mounting disc 5 includes the mounting ring 52 that is connected by brace rod 51, and the mounting ring 52 is provided with
Multigroup mounting bracket 53 for clamping the blade 1；After the mounting bracket 53 clamps the blade 1, the mounting ring 52 and its
On the blade 1 whole height be the oil drum 2 height 1/10；
Methods described comprises the following steps：
Step A, multiple blades 1 are clamped in the mounting disc 5 by same circular direction using the mounting bracket 53,
The valve closed between the cooling tank 3 and the oil drum 2, starts the oil pump of the heater 4, will be defeated in the cooling tank 3
The oil for sending sprays into the oil drum 2 after being heated to 180 DEG C by the mouth spray 21, when the deep fat in the oil drum 2 to the oil
During 1/3 height of bucket 2, the mounting disc 5 is fallen, make the bottom surface of the mounting bracket 53 to apart from the height of 2 bottom of the oil drum 1/10；
The oil pump of the heater 4 is closed, is stopped to the oil spout of the oil drum 2, the blade 1 is put in the deep fat of the oil drum 2
5-8 minutes；
Multiple blades 1 are clamped using the mounting bracket 53 by same circular direction in the mounting disc 5, that is,
Say, make the trailing edge hole 121 of the blade 1 as shown in figure 3, facing one direction.
The mounting bracket 53 can be the L-type auricle simply using bolt regulation, as long as the blade 1 can be clamped
Just can be with.Space between the brace rod 51 can ensure that deep fat has enough spaces to be flowed about 5 in the mounting disc.
Oil is heated to 180 DEG C and sprays into the oil drum 2 again by the heater 4, can so ensure the heat by spray process
After amount loss, the oily temperature in the oil drum 2 can still be maintained at more than 140 DEG C.
After the completion of this step, it can be ensured that the blade 1 is immersed in deep fat, the soak time of 5-8 minutes and described
The process that mounting disc 5 is sprayed when declining can ensure the low-melting alloy dissolving in most of exit.
Step B, opens the valve between the cooling tank 3 and the oil drum 2, makes to be dissolved with the deep fat stream of heat fusion joint alloy
Enter the cooling tank 3, the deep fat of 3 pairs of inflows of the cooling tank is cooled down, while starting the oil pump of the heater 4, continue
To oil spout in the oil drum 2, and the mounting disc 5 is started rotation according to the speed that 20-30 per minute turns, rotate 8-10 minutes
Afterwards, the mounting disc 5 is risen, the bottom surface of the mounting bracket 53 is risen to the top of the oil drum 2, complete the eutectic to the blade 1
The removal of point alloy.
By adjusting the oil pump of the valve between the cooling tank 3 and the oil drum 2 and the heater 4, can make
The oil mass that the cooling tank 3 must be flowed out to from the oil drum 2 is consistent with the oil mass sprayed into from the heater 4, so can ensure that
There are enough deep fats to dissolve low-melting alloy in the oil drum 2.
The cooling tank 3 can be the metal can for being surrounded with cooling heat transferring pipeline, be dissolved with the deep fat stream of low-melting alloy
After entering the cooling tank 3, cool down the low-melting alloy in oil by being cooled under the melting temperature of low-melting alloy solidifying
Admittedly separating, so can ensure that the oil for pumping into the heater 4 is free of low-melting alloy.
In a preferred embodiment, the chilling temperature of the cooling tank 3 is 80 DEG C, so on the one hand can ensure low melting point
The separation of alloy, on the other hand can reduce the energy ezpenditure of the heater 4.
The rotation of the speed that the 20-30 per minute of 8-10 minutes turns may be such that low-melting alloy in the blade 1 from
Accelerate dissolving under mental power function and depart from the inner chamber of the blade 1.
During the mounting disc 5 is risen, the deep fat that the mouth spray 21 sprays can be fuel-displaced in 5 liters of the mounting disc
Further the blade 1 is cleared up during face to the outside of the oil drum 2.
In a preferred embodiment, the direction of rotation of the mounting disc 5 can be to maintain the trailing edge hole 121 in rotation
The rear in direction, is so conducive to going out the low-melting alloy dissolving in the inner chamber of the blade 1 using the effect of liquid stream.
A kind of blade inner chamber low-melting alloy minimizing technology provided by the present invention, on the one hand effectively reduces low melting point conjunction
The golden removal time, the blade inner chamber noresidue that effective guarantee is gone after division operation is gone back in addition, can additionally be carried out continuously in batches low
Melting alloy goes division operation, substantially increases operating efficiency.
