[0002] At present, the inert gas atomization equipment (EIGA) is either imported from abroad or developed by itself, but the atomization efficiency is low, it can only be used alone, the actual use time is short, the waiting, clamping, vacuuming and other auxiliary time are long, and there are residual material heads. There is an urgent need for a bar feeding mechanism that can achieve continuous atomization and no redundant material heads, so as to greatly improve production efficiency, save costs and improve atomization efficiency. Summary of the invention

[0003] Purpose of the invention: In order to solve the current situation of low atomization efficiency of existing domestic inert gas protection gas atomization equipment in the background technology, we design a material rod feeding mechanism for inert gas protection atomization equipment, so as to greatly improve production efficiency, save costs and improve atomization efficiency.

[0004] The technical solutions adopted to solve the above problems are:

[0005] A material rod feeding mechanism of an inert gas protection atomization device comprises an EIGA atomization furnace melting chamber fixedly connected to the upper part of the atomization chamber of the EIGA atomization furnace, a lifting component and a feeding component.

[0006] The EIGA atomizing furnace smelting chamber is arranged above the feed port of the EIGA atomizing furnace atomizing furnace to clamp the rod material A. The lower end of the rod material A is provided with an induction coil for smelting the rod material. A sealing device and a cooling water interlayer are provided at the junction of the rod material A and the EIGA atomizing furnace smelting chamber.

[0007] The upper part of the EIGA atomizing furnace smelting chamber is also provided with a lifting assembly, including a lifting bracket, a screw pair and a lifting power motor. The upper and lower parts of the screw pair are provided with a lifting upper limit and a lifting lower limit. The screw pair is provided with a screw slider. The lifting power motor is fixed to the upper end of the lifting bracket, and its main shaft is connected to the screw pair through a coupling for transmission. The screw slider is fixedly connected with a hollow rotating table, and is transmitted to the hollow rotating table by the rotating power motor with the help of a connecting piece, and controls the middle bar B to rotate evenly and at a uniform speed. The bar B is fixed by a locking expansion sleeve.

[0008] Furthermore, an auxiliary sealing chamber is provided at the junction between the upper part of the EIGA atomizing furnace smelting chamber and the rod material A, and a sealing device is also provided at the upper end to ensure that no leakage occurs when the rod material is fed.

[0009] Furthermore, an auxiliary clamping device is provided on one side of the upper end of the rod A and fixed on the auxiliary sealing chamber, including a clamping cylinder and a clamping rod, which is used to replace the rod to improve the atomization efficiency.

[0010] Furthermore, one end of the rod B is a threaded hole and the other end is a threaded segment, both of which are of the same size and specification. The lower end is screwed and fixed to the rod A through a customized threaded hole, and the upper end is screwed and fixed to the threaded segment of the rod C to be used. When the rod A is used, the rod C is screwed on top of the rod B to continue the continuous atomization to save time.

[0011] Furthermore, the lower end of the rod A is configured as a cone, which cooperates with the induction coil to form metal atomization.

[0012] The beneficial effects of the present invention are as follows: the material rod feeding mechanism of the inert gas protection atomization equipment adopts a brand-new material rod feeding method, which can realize continuous feeding without redundant material heads, and can greatly improve production efficiency and save costs.
