Electron beam furnace bulk material feeding mechanism

Abstract

The invention belongs to the technical field of electron beam furnace smelting, and particularly relates to an electron beam furnace bulk material feeding mechanism. The mechanism comprises a bulk material cylinder and a bulk material cover, wherein discharging outlets are bilaterally symmetrically distributed at a bulk material cover flange, a material rod and a rotating and lifting mechanism thereof are arranged in the middle of the bulk material cover, the bottom of the material rod is a rotating piece, and the rotating piece floats up and down relative to the material rod within a certainrange. The rotating and lifting mechanism comprises a rotating and lifting shaft connected with a rotating motor, wherein the lifting motor is connected with the rotating motor through the lifting mechanism. The rotating motor drives a rotating lifting shaft, and the rotating piece rotates, so that materials enter a smelting chamber. When excessive materials are stacked and the state of the materials are dense, the phenomenon of clamping appears. Due to driving of the lifting motor, the rotating lifting shaft is driven, the rotating piece moves upwards. According to the material state, the gapdistance is adjusted, and the purpose of smooth discharging is achieved.

Description

technical field [0001] The invention belongs to the technical field of electron beam smelting, and in particular relates to a bulk material feeding mechanism for an electron beam furnace. Background technique [0002] Electron beam melting technology has unique advantages in the field of melting and refining titanium materials and titanium alloys. Electron beams are widely used for their high energy density, high melting temperature, and excellent purification effect in vacuum environment. During the smelting process, different customers provide raw materials in different states, and then require different feeding mechanisms to be configured in the complete set of electron beam smelting equipment according to customer needs. For shaving waste recycling, granular materials and similar irregular raw materials, the industry usually uses bulk material feeding mechanisms to realize material transportation. In view of the variety of raw material forms, it is difficult to cover a...
