Abstract
The utility model relates to the field of neodymium iron boron material production, in particular to a neodymium iron boron magnetic powder storage device which comprises a nitrogen tank for storing nitrogen, feed bins for storing neodymium iron boron magnetic powder, by-pass valves, a main valve and a nitrogen pipeline, wherein the by-pass valves are connected with the feed bins, and the main valve is connected with the nitrogen tank. A pressure meter is arranged on the nitrogen tank, every two feed bins form a group, the feed bins in each group are connected with the nitrogen tank through a three-way valve, and the by-pass valves are arranged among the feed bins and the three-way valves. One three-way valve replaces two common valves, the influence of excessive valves on the sealing performance of pipelines is effectively avoided, the pressure of the nitrogen tank is observed through the pressure meter, and the feed bins have nitrogen with enough pressure for preventing the neodymium iron boron from being oxidized.
Description
Technical field
The utility model relates to NdFeB material production field, specifically a kind of NdFeB magnetic powder memory storage.
Background technology
The production of NdFeB magnetic powder requires very high to anaerobic, because NdFeB magnetic powder is very easily oxidized, should avoid contacting with air in actual production.After nd-fe-b powder process, conventionally in the feed bin of sealing, preserve, but feed bin may have micro-leakage or leak tightness deficiency, often easily cause the oxidation of part magnetic, produce impurity, cause sintering end product quality nonconformity out even to be scrapped, the feed bin of the memory storage using in prior art is due to needs sealing and maintenance, often each feed bin need to be equipped with two valves, one for closed conduit, another is for seal silo, can cause leak tightness relatively to reduce but valve is many, operation inconvenience, and there is no a compression indicator, whether the pressure that is difficult to ensure card feed bin enough ensures that neodymium-iron-boron powder is not oxidized.
Utility model content
For overcoming above-mentioned technical matters, the utility model provides a kind of valve few, good airproof performance, easy to operate NdFeB magnetic powder memory storage.
Technical solution of the present utility model is, a kind of NdFeB magnetic powder memory storage is provided, comprise and store the nitrogen pot of nitrogen, the feed bin, the branch road valve being connected with described feed bin of storage NdFeB magnetic powder, main valve and the nitrogen pipeline being connected with described nitrogen pot, described nitrogen pot is provided with compression indicator, one group of every two composition of described feed bin, feed bin in every group is all connected with described nitrogen pot by a triple valve, and described branch road valve is located between feed bin and triple valve.
Adopt after said structure, the utility model neither affects the single maintenance to feed bin, also can be by a triple valve to two feed bin inflated with nitrogen, two common valves are replaced with a triple valve, the leak tightness that actv. has avoided valve to cross multipair pipeline impacts, observe the pressure of nitrogen pot by compression indicator, ensure that feed bin has the nitrogen of enough pressure to prevent that nd-fe-b is oxidized.
Described feed bin is more than three groups or three groups, is applicable to nd-fe-b and produces in enormous quantities.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model NdFeB magnetic powder memory storage;
Shown in figure 1, nitrogen pot; 2, feed bin; 3, triple valve; 4, main valve; 5, compression indicator; 6, branch road valve, 7, nitrogen pipeline.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further, but the utility model is not limited only to following examples.
A kind of NdFeB magnetic powder memory storage, comprise and store the nitrogen pot 1 of nitrogen, the feed bin 2, the branch road valve 6 being connected with described feed bin 2 of storage NdFeB magnetic powder, main valve 4 and the nitrogen pipeline 7 being connected with described nitrogen pot 1, described nitrogen pot 1 is provided with compression indicator 5, one group of every two composition of described feed bin 2, feed bin 2 in every group is all connected with described nitrogen pot 1 by a triple valve 3, and described branch road valve 6 is located between feed bin 2 and triple valve 3.Described feed bin 2 is three groups, totally six feed bins.
When use, in the time that the pressure of compression indicator 5 is qualified, main valve 4, branch road valve 6 are opened, triple valve 3 is opened to corresponding feed bin 2, after certain hour, switch to another feed bin 2 and keep a period of time, thereby preventing that NdFeB magnetic powder is not oxidized.
In the time that some feed bins 2 need repairing, the branch road valve 6 that only need to close feed bin 2 sides is opened triple valve 3 to another feed bin on the same group simultaneously, can detachable maintaining and can not affect whole memory storage.In the time that nitrogen pot 1 needs repairing, only main valve 4 need to be closed.This programme uses and keeps in repair easyly, is suitable for industrial applications.
Claims (2)
1. a NdFeB magnetic powder memory storage, comprise the nitrogen pot (1) of storing nitrogen, the feed bin (2) of storage NdFeB magnetic powder, the branch road valve (6) being connected with described feed bin (2), the main valve (4) being connected with described nitrogen pot (1) and nitrogen pipeline (7), it is characterized in that: described nitrogen pot (1) is provided with compression indicator (5), one group of every two composition of described feed bin (2), feed bin (2) in every group is all connected with described nitrogen pot (1) by a triple valve (3), described branch road valve (6) is located between feed bin (2) and triple valve (3).
