Currently, the current state of the art commonly used in the industry is as follows: for the neodymium-iron-boron rare earth permanent magnet material, the current main manufacturing process flow is as follows: smelting alloy, hydrotreating, coarse powder mixing, fine powder mixing, orientation pressing, vacuum sintering, and metering and filling the mixed powder in the early stage of orientation pressing under the protection of inert gas.

At present, because of large brand and model differences of presses used by various enterprises, the problems of various specifications and poor interchangeability exist when corresponding weighing and filling machines are matched. Meanwhile, the existing equipment has narrow range; the weighing speed is low; and the material level detection is unreliable. In the existing production process, when the raw material tank is in butt joint with equipment, a flexible hose is generally adopted to finish butt joint, the method has the problems of high labor intensity and more time consumption, the flexible hose adopted in butt joint is easy to age after long-time work, if the flexible hose is not replaced in time, the discharged material after the hose is broken can be spontaneously burned when encountering air, and the personal safety of operators is greatly endangered. In the operation process, an operator on the further site sometimes forgets to release pressure to the raw material tank to directly butt-joint the raw material tank with equipment, and after the butterfly valve is opened, raw material can be rapidly released out of the full equipment under the action of the pressure in the tank to cause a safety accident.

To sum up, the problems of the prior art are:

(1) The existing neodymium iron boron rare earth permanent magnet material metering filling machine has a narrow range; the weighing speed is low; the unreliable material level detection problem;

(2) In the existing production process, a hose used for butt joint of a raw material tank and equipment is easy to age after long-time working, if the hose is not replaced in time, the discharged material can be spontaneously burned when encountering air after the hose is broken, so that the personal safety of operators is greatly endangered;

(3) In the operation process, an operator on site sometimes forgets to release pressure to the raw material tank to directly dock the raw material tank with equipment, and after the butterfly valve is opened, raw material can be quickly released out of the full equipment under the action of the pressure in the tank to cause safety accidents.

The difficulty of solving the technical problems is as follows: how to widen the range of the metering and filling machine of the neodymium iron boron rare earth permanent magnet material; the speed and the reliability of material level detection are improved; how to improve the mode of the butt joint of the charging bucket and the equipment, and ensure the personal safety of operators.

Meaning of solving the technical problems: the technical problem is solved, the production sales rate and the reliability of the neodymium iron boron rare earth permanent magnet material metering filling machine can be improved, meanwhile, the labor intensity of workers is reduced conveniently and rapidly when the charging bucket is in butt joint with equipment, and the safety problem that raw materials are discharged due to the fact that a rubber pipe is broken and the raw material tank is not decompressed is solved.

Disclosure of Invention
