Plasma rotation electrode powder production feeding device

Abstract

A plasma rotation electrode powder production feeding device comprises a material box upper cover which is connected with a material box; a feeding hole is formed in the top of the material box upper cover; the feeding hole is sealed through a feeding hole sealing device; a material cabin is distributed inside the material box; the material box is matched with a discharging sliding plate through a shifting fork at the bottom of the material box; the discharging sliding plate is connected with a plasma rotation electrode powder production device; a flange connector is connected with a vacuum and inert gas system; raw material bars are sequentially arranged inside the material cabin from the feeding hole, after the material cabin is filled up, the feeding hole sealing device is started to enable the feeding hole sealing device and the material box upper cover to be well sealed, the vacuum system is started to enable gases inside the device to be extracted from the flange connector, and then inertia protective gases are inflated inside the device; the material cabin is rotated, meanwhile a shifting fork motor is started to enable the shifting fork to rotate, then bar materials enter the shifting fork from the material cabin, the shifting fork rotates, and when the material cabin rotates to an opening below, the bar materials are sent to the plasma rotation electrode powder production device along the discharging sliding plate. The plasma rotation electrode powder production feeding device is simple in structure, convenient to operate, time-saving, labor-saving, safe and reliable.

Description

technical field [0001] The invention relates to an industrial feeding device, in particular to a plasma rotating electrode powder making feeding device. Background technique [0002] The plasma rotating electrode powder making process is an important process technology for preparing high-temperature alloy and titanium alloy spherical powder for aero-engine, rocket engine, gas turbine power plant high-load parts and chemical corrosion-resistant components. [0003] At present, in the plasma rotary electrode powder making process, the raw material rods enter the melting chamber of the atomization equipment in the following way: the end of the previous raw material rod is processed into a threaded hole, and the front end of the latter raw material rod is processed into an external thread, and then fed into The spray chamber realizes the continuous feeding of raw materials to increase the production rate. The defect of this method is: since the bar material enters the melting c...
