Detailed Description
The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.
As shown in FIGS. 1 to 3:
example 1
A blanking device for nickel ore powder smelting comprises a support 1, wherein the support 1 is used as a supporting structure of an equipment component, a driving motor 3 and a speed reducer 4 are fixedly arranged on the support, the driving motor 3 drives the speed reducer 4, the speed reducer 4 realizes the speed reduction of the rotating speed of the driving motor 3, the speed reducer 4 reduces the speed by power and is connected with a rotating shaft 5 through an output shaft of the rotating shaft, the rotating shaft 5 penetrates through a shell 2, a plurality of blanking baffles 6 are arranged on the rotating shaft 5, the blanking baffles 6 are circumferentially and uniformly distributed on the rotating shaft 5, and the size of each blanking baffle 6 is matched with the size of an inner cavity of the shell 2; the top of casing 2 sets up feed inlet 7, and the bottom sets up discharge gate 8, and the nickel ore powder that comes out from the inlet pipe falls on rotation axis 5 and unloading baffle 6 to through the rotation of rotation axis 5, make the ejection of compact of nickel powdered ore from discharge gate 8, fall into and carry out the smelting of nickel alloy in the rotary kiln, high temperature flue gas in the rotary kiln is because stopping of unloading baffle 6, and can not the direct reflux feed inlet 7, thereby has avoided the high temperature damage of high temperature flue gas to the inlet pipe.
In order to avoid the nickel ore powder from being bonded on the blanking baffle 6 due to sintering under the influence of high temperature when falling onto the blanking baffle 6, the length of the blanking baffle is slightly larger than the diameter of the inner cavity of the shell, and the blanking baffle is set into a structural form with adjustable length. When the blanking baffle rotates to the tail end of the feeding hole or the discharging hole, the blanking baffle collides with the inner cavity of the shell to vibrate, so that nickel ore powder on the blanking baffle falls off to avoid bonding, and meanwhile, the length of the blanking baffle is changed by the driving force of the continuous rotation of the rotating shaft, so that the blanking baffle can rotate in the inner cavity of the shell 2 to complete the circular rotation and vibration of the blanking baffle. In this embodiment, the blanking baffle 6 is made of an elastic deformable plate, and the driving force of the rotation of the rotating shaft causes the blanking baffle 6 to bend, thereby reducing the distance between the blanking baffle 6 and the inner cavity wall of the shell, so that the blanking baffle can continue to rotate in the inner cavity of the shell 2. In order to better realize the elastic deformation of the blanking baffle 6, the blanking baffle 6 is arranged to be arc-shaped.
Example 2
On embodiment 1's basis, its basic unit support 1, casing 2, driving motor 3, speed reducer 4, rotation axis 5 and feed inlet 7 and discharge gate 8 keep the same form that sets up, unloading baffle 6 adopts the rigid plate preparation to form to through articulated mode swing joint on rotation axis 5, spacing through elastic return means simultaneously, make it rotate under the condition of extra effort, thereby change the distance position relation between the terminal of unloading baffle 6 and the casing 2 inner chamber and realize its endless rotation and vibration.
In this embodiment, the elastic return device can be realized by using a simple spring 9, and meanwhile, for better limiting the blanking baffles 6, two springs 9 for limiting each blanking baffle 6 are provided and are respectively located at two sides of each blanking baffle 6. When the blanking baffle rotates to the tail end of the feeding hole or the discharging hole, the blanking baffle collides with the inner cavity of the shell to vibrate, so that nickel ore powder on the blanking baffle falls off to avoid bonding, and meanwhile, the blanking baffle 6 rotates along a hinged shaft movably connected with the rotating shaft 5 and stretches or compresses the spring through the driving force of the continuous rotation of the rotating shaft, so that the spring smoothly passes through the wall of the inner cavity of the shell to realize the circular rotation and vibration of the spring.
The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, but all the insubstantial modifications or changes made within the spirit and scope of the main design of the present invention, which still solve the technical problems consistent with the present invention, should be included in the scope of the present invention.
