Abstract
The utility model discloses a device for adding an antioxidant, which is a container. An antioxidant inlet is formed on the upper side of the container; the antioxidant inlet is provided with an input valve and an antioxidant outlet is formed on the lower side of the container; the antioxidant outlet is provided with an output valve and is connected with a connection air pipe; a nitrogen input opening is formed on the lateral upper side of the container; and a nitrogen valve is mounted on the nitrogen input opening. The device disclosed by the utility model utilizes nitrogen pressure to directly convey the antioxidant into a neodymium iron boron powder pot and the antioxidant is not contacted with air, so as to effectively prevent oxygen from entering the powder pot to oxidize the powder in an adding process and solve the problem that the antioxidant is stuck on the valve of the powder pot and is not easy to clean; and meanwhile, steps are simplified and the device is easy to operate.
Description
Technical field
The utility model relates to a kind of device that adds antioxidant.
Background technology
Along with the development of technology such as the development of society, particularly wind-power electricity generation, electric automobile, frequency conversion engine, make more and more higher to the neodymium iron boron performance demands.
High-performance Ne-Fe-B requires powder process link powder to want thin, and the finished product oxygen content is low, but powder is more thin, and surface-active is more strong, and more easy and oxygen reaction causes oxygen content to increase in the production process, therefore needs to add in neodymium-iron-boron powder antioxidant.
The adding method of existing antioxidant is that the last butterfly valve of Nd-Fe-B powder jar is opened, and antioxidant is poured on down on the butterfly valve, will go up butterfly valve then and bar up, and will descend butterfly valve to open, and antioxidant is flowed in the powder jar, then lower valve is barred up.With powder jar rotation rolling, antioxidant evenly is coated on the powder particle surface again.More than add the antioxidant method and have following shortcoming: air can enter the powder jar between (1) two butterfly valve, the part powder can with oxygen reaction generation oxidation; (2) a large amount of antioxidants can be bonded at the butterfly valve surface, and the one, waste, the 2nd, be difficult to cleaning, simultaneously perishable valve sealing ring; (3) frequent controlled valve, complex operation, fragile valve simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of device that adds antioxidant, to prevent that effectively the interpolation process from causing oxygen to enter the powder jar and causing the powder oxidation, solves antioxidant and is bonded at the not problem of easy to clean of powder tank valve, simplifies step simultaneously, easy operating.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of device that adds antioxidant, it is a container, the top of container forms the antioxidant entrance, the antioxidant entrance is installed the input valve, the below of container forms the antioxidant outlet, the antioxidant outlet is installed output valve and is connected tracheae, and the side top of container forms the nitrogen input port, and the nitrogen valve is installed in the nitrogen input port.
Described container in a tubular form, the antioxidant of container outlet is from top to bottom dwindled gradually.
After adopting such scheme, the utility model is connected by the antioxidant valve of tracheae with Nd-Fe-B powder jar side top, whole device is connected with the Nd-Fe-B powder jar, during use, successively open the input valve of antioxidant entrance and the output valve of antioxidant outlet, a certain amount of antioxidant is added in the container of this device, open the nitrogen valve of nitrogen input port then, input nitrogen makes the air in the container discharge from the antioxidant entrance, close the input valve of antioxidant entrance again, nitrogen pressure increases in the container, open the antioxidant valve of Nd-Fe-B powder jar, antioxidant enters in the Nd-Fe-B powder jar with nitrogen by tracheae, closes the antioxidant valve of Nd-Fe-B powder jar at last, tracheae and Nd-Fe-B powder jar are separated, and antioxidant adds EO.
The utility model makes antioxidant directly utilize nitrogen pressure to enter in the Nd-Fe-B powder jar, do not contact with air, can prevent effectively that the interpolation process from causing oxygen to enter the powder jar and causing the powder oxidation, solve antioxidant and be bonded at the not problem of easy to clean of powder tank valve, simplify step simultaneously, easy operating.
Description of drawings
Fig. 1 is main pseudosection of the present utility model.
Label declaration
Container 1, input valve 2, output valve 3, tracheae 4, nitrogen valve 5, exhaust outlet 6, butterfly valve 7, antioxidant valve 8, Nd-Fe-B powder jar 9.
The specific embodiment
As shown in Figure 1, a kind of device that adds antioxidant that the utility model discloses, it is a container 1, the top of container 1 forms the antioxidant entrance, the antioxidant entrance is installed input valve 2, the below of container 1 forms the antioxidant outlet, the antioxidant outlet is installed output valve 3 and is connected tracheae 4, tracheae 4 is used for being connected with the antioxidant valve 8 of Nd-Fe-B powder jar 9 sides top, whole device of the present utility model is connected with Nd-Fe-B powder jar 9, the side top of container 1 also forms the nitrogen input port, and nitrogen valve 5 is installed in the nitrogen input port.In order to optimize structure, make the interpolation operation more smooth and easy, the container 1 of this embodiment designs in a tubular form, and the outlet of the antioxidant of container 1 is from top to bottom dwindled gradually.
The utility model is to dock with Nd-Fe-B powder jar 9 by tracheae 4, and the top feeding mouth of Nd-Fe-B powder jar 9 has been installed two butterfly valves 7, and exhaust outlet 6 is also offered in the side top of Nd-Fe-B powder jar 9.Neodymium-iron-boron powder is stored in the Nd-Fe-B powder jar 9.
When the utility model uses, successively open the input valve 2 of antioxidant entrance and the output valve 3 of antioxidant outlet, a certain amount of antioxidant is added in the container 1, open the nitrogen valve 5 of nitrogen input port then, in container 1, import nitrogen, air in the container 1 is discharged from the input valve 2 of antioxidant entrance, close the input valve 2 of antioxidant entrance again, nitrogen pressure increases in the container 1, open the antioxidant valve 8 of Nd-Fe-B powder jar 9, antioxidant enters in the Nd-Fe-B powder jar 9 with nitrogen by tracheae 4 under the nitrogen pressure effect, after treating that antioxidant all enters in the Nd-Fe-B powder jar 9, close the antioxidant valve 8 of Nd-Fe-B powder jar 9 at last, tracheae 4 and Nd-Fe-B powder jar 9 are separated, antioxidant adds EO.Whole interpolation process all is to carry out under protection of nitrogen gas, can effectively avoid the oxidation of powder, solves antioxidant and is bonded at the not problem of easy to clean of powder tank valve, simplifies step simultaneously, easy operating.
Being specific embodiment of the utility model only below, is not the restriction to protection domain of the present utility model.All equivalent variations of doing according to the mentality of designing of this case all fall into the protection domain of this case.
