In order to realize continuous feeding in the electrode transmission chamber 10 and atomization preparation of the continuous rotating electrode, the electrode bar stock 100 enters into atomization powder preparation environment from the atmospheric environment, in the process, the relief of the vacuum environment and the protective atmosphere environment in the equipment is involved, so that the vacuum environment and the protective atmosphere environment of a feeding link and an electrode transmission link need to be reestablished, the consumed time is long, energy and gas are wasted, the interruption time of powder making is long, and the efficiency and the capacity of atomized powder making are influenced, therefore, the invention solves the problem by introducing a transition bin, as shown in FIG. 1, the first aspect of the present invention provides a technical solution, a continuous feeding mechanism for atomizing and pulverizing by a rotary electrode, comprising an electrode transmission chamber 10 and a transition bin 50, a gate valve 60 is arranged between the transition bin 50 and the electrode transmission chamber 10, the control electrode transmission chamber 10 and the cavities in the transition bin 50 are independent or communicated with each other.
Therefore, when the electrode transmission chamber 10 is used, and the electrode bar stock in the electrode transmission chamber 10 is consumed by the atomization powder making process, can be supplemented by electrode bars in a transition bin 50 which is communicated with the electrode transmission chamber 10 and establishes a vacuum protective atmosphere environment, in the normal milling process of the electrode bar, the connection between the electrode transmission chamber 10 and the cavity of the transition bin 50 is cut off, the vacuum protective atmosphere environment is normally maintained in the electrode transmission chamber 10, the vacuum protective atmosphere in the transition bin 50 is independently removed, electrode bar materials are supplemented into the cavity of the transition bin, then the vacuum protective atmosphere environment in the transition bin 50 is reestablished to be the same as that of the electrode transmission chamber 10, the transition storage bin 50 can be communicated with the electrode transmission chamber 10 again through a control component such as a gate valve, so that feeding from the transition storage bin 50 into the electrode transmission chamber 10 is realized. The above-mentioned two-chamber division-transition bin environment release-transition bin environment reconstruction-two-chamber communication process is repeated, so that the continuous feeding into the electrode transmission chamber 10 is realized.
In the process, only the transition bin is subjected to environment reconstruction, and the electrode transmission chamber is not required to be subjected to environment reconstruction (vacuumizing and inert gas protection), so that the required inert gas consumption is less, the reconstruction process is short, and the production interruption time is greatly reduced.
