Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum heat treatment furnaces, and particularly relates to a continuous feeding device for vacuum heat treatment furnaces. Background Art

[0002] Patent announcement number CN210486476U discloses a continuous feeding device for a vacuum melting furnace, comprising a furnace body, a frame is mounted at the bottom of the furnace body, a furnace cover is mounted on the top of the furnace cover, a drop hopper is fixedly mounted on the top of the furnace cover, a discharge valve is mounted on the bottom of one side of the drop hopper, a drop tray is mounted on the top of the drop tray, a barrel is mounted on the drop tray, the barrel is rotatably mounted just above the drop tray, and a receiving tray is mounted on the inner side of the furnace body; a barrel is mounted on the top of the melting furnace, and a drop tray is mounted at the bottom of the barrel. When the melting furnace is melting, the barrel rotates, and the alloy material falls out of the drop tray. The material falls from the material tray into the material hopper and falls into the furnace body through the material discharge valve at the bottom of the material discharge hopper. A serpentine rack is installed inside the furnace body, and a tray is installed on the top of the serpentine rack. When the smelting furnace is dropping materials, the metal material falls into the material receiving tray and falls into the crucible inside the furnace body through the serpentine rack to prevent the material from being dropped too high and the metal liquid from splashing. The above-mentioned continuous feeding device cannot feed the raw materials separately each time, and the smelting furnace needs to be opened and closed manually. Automatic feeding is not possible, and the amount of each feeding cannot be controlled, which reduces practicality. For this reason, we propose a continuous feeding device for a vacuum heat treatment furnace. Utility Model Content
