It is discharged at mouthful, offers feeding port 3 and auxiliary material feeding port 4 respectively at left and right sides of the upper side wall of furnace body 1, original is added from feeding port 3
Expect ore, the auxiliary material of auxiliary is added from auxiliary material feeding port 4, grafting is equipped with telescopic device 5 on the left of the upper side wall of furnace body 1, stretches
The internal structure of compression apparatus 5 can stretch, and then the position of 6 left end of adjustable buffer board, and the lower end of telescopic device 5 rotates dress
Equipped with buffer board 6, buffer board 6 is located at the underface of feeding port 3, and opposite turn can occur with the lower end of telescopic device 5 for buffer board 6
It is dynamic, and buffer board 6 is located in the inner cavity of furnace body 1, the right side wall of buffer board 6 is fixedly installed with chain 7, and the upper side wall of furnace body 1 is solid
Dingan County is equipped with regulating device 8, and chain 7 is assemblied at regulating device 8 through the winding of furnace body 1, and regulating device 8 is used for chain 7
Position adjusting is carried out, and then the position of the right end of buffer board 6 is adjusted, after overregulating, buffer board 6 can be enabled to be in a left side
High right low state, therefore fallen on buffer board 6 when raw ore falls Shi Huixian, it is fallen on later along slanting buffer board 6
At the bottom wall of 1 inner cavity of furnace body, this under the barrier action of buffer board 6, greatly reduces raw ore to 1 inner cavity of furnace body in the process
The impact force of bottom wall plays the role of protecting furnace body 1, can increase the service life of this molten bath furnace.
Specifically, telescopic device 5 includes rectangular cylinder 51, and rectangular cylinder 51 is plugged and fixed in the upper side wall of furnace body 1, rectangle
The inner sidewall of cylinder 51 is plugged with rectangular slab 52, and rectangular slab 52 can move up and down in rectangular cylinder 51, the upper and lower sides of rectangular slab 52
Wall is fixedly installed with limit plate 53, and limit plate 53 is defined the highest and extreme lower position of rectangular slab 52, and then to buffering
The position of 6 left end of plate carries out range restriction, is symmetrically fixedly installed with fixed plate 54, two fixations before and after the lower wall of limit plate 53
It is fixedly installed with fixing axle 55 between plate 54, rotating block 9 is fixedly installed on the left of the upper side wall of buffer board 6, and rotating block 9 is socketed
In the lateral wall of fixing axle 55, buffer board 6 can be rotated by rotating block 9 along fixing axle 55, as shown in Figure 3, it is known that rotation
The shape of block 9, upside left side is cambered surface, and right side is bonded with limit plate 53, therefore buffer board 6 is enabled to be only capable of deflecting to the right,
Therefore will also realize that, when shrinking chain 7, enable moved on 6 right end of buffer board it is parallel with left end after, buffer board 6 is whole to be will be shifted up, and band
Dynamic rectangular slab 52 moves up in rectangular cylinder 51.
Specifically, regulating device 8 includes support plate 81, and support plate 81 is fixedly installed in the upper side wall of furnace body 1, support
Side plate 82 is symmetrically fixedly installed with before and after the upper side wall of plate 81, the front side wall of front side side plate 82 is plugged with rotation axis 83, and rotates
The rear end of axis 83 is plugged on the front side wall of rear side side plate 82, and rotation axis 83 can rotate, and the lateral wall of rotation axis 83 is fixedly mounted
There is cylindrical piece 84, and chain 7 is wound in the lateral wall of cylindrical piece 84, the front side wall of rotation axis 83 offers rectangular channel 85, rectangle
The inner sidewall of slot 85 is plugged with rectangular shaft 86, and rectangular shaft 86 can move in rectangular channel 85, due to rectangular channel 85 and rectangular shaft
86 be the rectangular shape to match, therefore will drive rotation axis 83 when rectangular shaft 86 rotates and rotate, the lateral wall of rectangular shaft 86
It is fixedly installed with handle 87, drives rectangular shaft 86 to rotate by handle 87, is fixedly installed on rear side of the front side wall of front side side plate 82
Limited block 88 as shown in Fig. 2, limited block 88 blocks the position of handle 87 at this time, and then limits cylindrical piece 84 and chain 7
It is fixed, realize the restriction to 6 position of buffer board, when pull handle 87, after enabling rectangular shaft 86 remove a distance out of rectangular channel 85,
When limited block 88 being enabled no longer to limit the position of handle 87, chain 7 can be adjusted at this time, and then adjust the position of buffer board 6
It sets.
Specifically, the lateral wall of furnace body 1 is uniformly provided with venthole 10, for providing air in furnace body 1.
Working principle: this needs adding raw materials ore for melting low-sulfur phosphorus ultra-purity pig iron or the molten bath furnace of pig iron containing vanadium
When, the lid of feeding port 3 is removed, then pull handle 87, enables limited block 88 no longer limit the position of handle 87, rotate at this time
Handle 87, slowly lengthen chain 7, and buffer board 6 can move down under gravity at this time, when rectangular slab 52 moves to lower side position
Afterwards, continue the chain 7 that lengthens, buffer board 6 can deflect along fixing axle 55 at this time, form the state of right low left high, then
Handle 87 is pushed, limited block 88 is enabled to fix the position of buffer board 6 position restriction of handle 87, it then can be from feeding port 3
Locate adding raw materials ore, ore can first be fallen on buffer board 6, and 1 inner cavity of furnace body is fallen on after the resistance of buffer board 6 and guiding
At bottom wall, therefore the impact force of 1 bottom wall of furnace body is substantially reduced, increases the service life of this molten bath furnace, later on reverse operating
Process is stated, buffer board 6 is enabled to revert to state shown in Fig. 1, melting work can be carried out later.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
