Description
Technical field
The utility model relates to field of magnetic material, and in particular to a kind of mixing agitator of neodymium iron boron micropowder.
Background technique
Sintered NdFeB is just being widely used in the magnetoelectricity neck of industrial equipment because of its excellent magnetic property and high-coercive force at present
Domain.Sintered NdFeB mixes powder-compression moulding-sintering etc. in production preparation process, by melting-hydrogen breaking-airflow milling powder-
Process flow needs to be added including stirring again after the additives such as antioxidant, lubricant wherein mixing in powder step in neodymium iron boron micropowder
It mixes uniformly, this kind of additive is mostly organic solvent.Current existing neodymium iron boron micropowder blending processes of powders is that first neodymium iron boron micropowder is filled
Enter in powder can container, then organic additive solution is poured directly into neodymium iron boron micropowder；Finally by the difference fortune of powder tank
Flowing mode is uniformly mixed neodymium iron boron micropowder and organic additive solution.Since organic additive solution is in adition process
In be regional reunite in itself, it is impossible to each region of powder can container is distributed to, so as to cause the neodymium iron in powder can container
Boron micro mist some is added agent cladding, and some is not wrapped by but；Keep carbon content in the neodymium iron boron blank finally worked it out uneven
It is even, to influence the consistency of product.
Utility model content
The main purpose of the utility model is to provide a kind of mixing agitator of neodymium iron boron micropowder, improves neodymium iron boron micropowder
During mixed powder, so that additive is uniformly dispersed, improve the consistency of product.
In order to realize the purpose of above-mentioned utility model, the technical scheme adopted by the utility model is that:
A kind of mixing agitator of neodymium iron boron micropowder, including powder tank, powder tank middle part level are inserted with one end sealing
Charge pipe, the sealed end of the charge pipe is welded on powder top tank structure, open end is located at outside powder tank and respectively with additive
Storage tank, nitrogen pump connection；Charge pipe inside powder tank is connected with multiple conduits, one end of the conduit and charge pipe it is interior
Chamber connection, other end sealing welding are on powder top tank structure；The conduit and atomization is equipped on the charge pipe inside powder tank
Nozzle.
The open end of further scheme, the charge pipe is equipped with sealing-plug.
Further scheme, the atomizer are vertically mounted in the middle part of the conduit between adjacent charge pipe or in charge pipe
Portion position, the spray direction of atomizer is perpendicular to conduit and downwards.
Further scheme, the powder tank, atomizer, conduit and charge pipe material be stainless steel material.
The charge pipe is located on the centre rotational axis of powder tank.
In use, first neodymium iron boron micropowder is fitted into powder tank, nitrogen pump and additive storage tank are then opened, into charge pipe
High pressure nitrogen and organic additive is added, high pressure nitrogen drives organic additive to enter each conduit from charge pipe, then from
It is atomized into misty liquid droplets in each atomizer to be distributed in powder tank in neodymium iron boron micropowder, powder tank is carried out along A-A axis direction
Rotary motion, so that organic additive and neodymium iron boron micropowder be made to be uniformly mixed, i.e., all neodymium iron boron micropowders are all added agent packet
It covers, makes that carbon content is uniform in the neodymium iron boron blank finally worked it out, homogeneity of product is high.
Powder tank is rotated along axis where charge pipe, and charge pipe will not change position with the movement of powder tank.
In mixing whipping process, the organic additive for spraying into atomization is discontinuous, and it is not low that number is sprayed into entire mixing process
In 20 times, atomisation time 1-5s.When not feeding, open end is sealed charge pipe with sealing-plug, is guaranteed in powder tank
Not entering air is sealing state.Terminate in mixed powder operation, mixed material is removed, is then passed through from the open end of charge pipe
High pressure nitrogen clears up atomizer.
Since the adding manner of organic additive is added by way of atomization during powder tank mixes powder, misty has
Machine additive can be uniformly dispersed in powder can container each region, so as to be uniformly coated in neodymium iron boron micropowder.
The mixing agitator of the utility model can be such that organic additive is uniformly distributed in neodymium iron boron micropowder, improve neodymium iron
The consistency of boron product composition and performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model,
Fig. 2 is A-A cross-sectional view in Fig. 1,
In figure: 1- powder tank, 2- charge pipe, 3- sealing-plug, 4- conduit, 5- atomizer.
Specific embodiment
As shown in Figure 1, 2, a kind of mixing agitator of neodymium iron boron micropowder, including powder tank 1,1 middle part of powder tank are horizontal
It is inserted with the charge pipe 2 of one end sealing, the sealed end of the charge pipe 2 is welded on 1 inner wall of powder tank, open end is located at powder tank 1
Outside is simultaneously connected with additive storage tank, nitrogen pump respectively；Charge pipe 2 inside powder tank 1 is connected with multiple conduits 4, described
One end of conduit 4 is connected to the inner cavity of charge pipe 2, other end sealing welding is on 1 inner wall of powder tank；The conduit 4 and be located at powder
Atomizer 5 is equipped on charge pipe 2 inside tank 1.
The open end of further scheme, the charge pipe 2 is equipped with sealing-plug 3.
