Abstract
The utility model relates to a charging auxiliary device for a neodymium ion boron jet mill. The charging auxiliary device for the neodymium ion boron jet mill comprises an electric machine (1), a first coupler (2), a reducer (3), a second coupler (4), a support base (5), a spiral head (6), a pipeline (7) and a charging hopper (8), wherein the electric machine (1), the first coupler (2), the reducer (3), the second coupler (4), the support base (5) and the spiral head (6) are connected in series sequentially, the pipeline (7) is arranged on the periphery of the spiral head (6), and the pipeline (7) is connected with a discharge hole of the discharge hopper (8). According to the charging auxiliary device for the neodymium ion boron jet mill, a spiral feeding mode is adopted, compared with a vibration feeding mode, blanking is more uniform, the weight of a mill chamber is steadier, and the grain size distribution of milled powder is more uniform.
Description
Technical field
The utility model relates to the neodymium-iron-boron air stream millby field, is specifically related to a kind of reinforced servicing unit of neodymium-iron-boron air stream millby of stable blanking.
Background technology
The reinforced servicing unit of existing airflow milling is the vibration-type blanking, because blanking is to add Action of Gravity Field by vibrations to carry out blanking, therefore, when material instantly is larger, often being stuck in entrance builds bridge, need the people to knock by hand blanking, at this moment, the weight of airflow milling mill chamber will reduce, if powder is too thin, blanking is within some time period so, and the indoor weight of airflow milling mill will increase, the unexpected increase of this mill chamber weight and the granularity that reduces airflow milling powder suddenly do very large harm, can cause the size distribution of airflow milling inhomogeneous.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of more stable, guarantees the reinforced servicing unit of the better a kind of neodymium-iron-boron air stream millby of granularity of the powder that airflow milling grinds.
The technical solution of the utility model: a kind of neodymium-iron-boron air stream millby servicing unit that feeds in raw material, it comprises: motor 1, the first shaft coupling 2, decelerator 3, the second shaft couplings 4, supporting base 5, spiral head 6, pipeline 7 and charging hopper 8, motor 1, the first shaft coupling 2, decelerator 3, the second shaft coupling 4, supporting base 5, spiral head 6 order serial connections, the periphery of described spiral head 6 is provided with pipeline 7, and pipeline 7 is connected with the discharging opening of charging hopper 8.
For even blanking, guarantee the stable rotation of spiral head, the speed reducing ratio of described decelerator 3 is set to 1:29.
The utility model compared with prior art has following beneficial effect: the utility model is owing to adopting the screw feed mode than the vibrations feeding manner, can more uniform blanking, and mill chamber weight is more stable, and the size distribution that grinds powder is more even.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
as shown in Figure 1: a kind of neodymium-iron-boron air stream millby servicing unit that feeds in raw material, it comprises: motor 1, the first shaft coupling 2, decelerator 3, the second shaft coupling 4, supporting base 5, spiral head 6, pipeline 7 and charging hopper 8, the output of motor 1 is connected with the first shaft coupling 2, the first shaft coupling 2 is connected with the input of decelerator 3 again, the output of decelerator 3 is connected with the second shaft coupling 4, the second shaft coupling 4 is connected with supporting base 5, supporting base 5 is connected with spiral head 6, the periphery of spiral head 6 is provided with pipeline 7, pipeline 7 is connected with the discharging opening of charging hopper 8, the speed reducing ratio of decelerator 3 is 1:29.
This device is after electric motor starting, by shaft coupling and decelerator, drive rightmost spiral head rotation, then begin to feed in raw material from charging hopper, under stable spiral head centripetal force effect, powder is by lower indoor to the airflow milling mill uniformly, and then the operation principle according to airflow milling grinds size distribution powder more uniformly.
