Abstract
The invention discloses a dust filtering gathering apparatus which is applied to equipment for preparing neodymium-iron-boron rare-earth alloy powder, and the equipment possesses an exhaust valve. The dust filtering gathering apparatus comprises a container, a filter screen and an air inlet pipe; the container is inside provide with an absorption liquid which divides the internal chamber of the container into a filtering chamber and an exhausting chamber; an exhaust port is arranged at the exhausting chamber part of the container; the filter screen is spread on the liquid surface of the absorption liquid in the container; and one end of the air inlet pipe is communicated with the exhaust valve, and the air inlet pipe penetrates through the container and stretches into the interior of the absorption liquid. The apparatus is capable of gathering alloy powder during preparation of the neodymium-iron-boron rare-earth permanent-magnet alloy powder, reducing dust in air, improving working environment, eliminating safety hidden trouble, also reducing material waste, reducing cost and improving economic benefit.
Description
Technical field
The present invention relates to neodymium iron boron production field, particularly a kind of dust-filtering gathering-device of producing permanent-magnet rare-earth NdFeB alloy powder.
Background technology
Nd-Fe-B rare earth permanent magnetic material is the strongest permanent-magnet material of current magnetic property, has the title of " magnetic king ", and it is widely used.Powder process is the critical process that Nd-Fe-B rare earth permanent magnetic material is produced, the milling method that most company adopts is to carry out airflow milling after broken during broken hydrogen powder is carried out again, in pulverizing process, there is a large amount of dust-containing air streams to produce, in wherein adopting, broken equipment has electromagnetic exhaust valve at fan outlet place, and gas is entered in air.
There is following defect in this equipment: in the gas that (1) air bleeding valve is discharged, contains a large amount of alloy powders, cause a large amount of dust that suspend in air, cause poor working environment, and staff's health is had to certain injury; (2) after the permanent-magnet rare-earth NdFeB alloy powder of discharging contacts with air, there is certain potential safety hazard in meeting spontaneous combustion; (3) a large amount of alloy powders is discharged in air by the equipment of taking out of, causes material waste, cost up.
The information that is disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
Summary of the invention
The object of the present invention is to provide a kind of dust-filtering gathering-device, can be collected in the alloy powder of producing in permanent-magnet rare-earth NdFeB alloy powder, reduce airborne dust, improve working environment, eliminate safe hidden trouble, and can reduce material waste, reduce costs, increase economic efficiency.
For achieving the above object, the invention provides a kind of dust-filtering gathering-device, it is for producing the equipment of NdFeB rear-earth alloyed powder, equipment has air bleeding valve, this dust-filtering gathering-device comprises: container, absorption liquid is housed in it, and the inner chamber of container is divided into filter chamber and discharge chamber by absorption liquid, and the discharge chamber part of container is provided with exhaust outlet; Filter screen, it is laid on the liquid level of the absorption liquid in container; Air inlet pipe, its one end is used for connecting with air bleeding valve, and air inlet pipe is through container and stretch into absorption liquid inside.
Preferably, filter screen upper surface is provided with drying layer.
Preferably, air inlet pipe stretches into absorption liquid inside through the discharge chamber portion of container.
Compared with prior art, the present invention has following beneficial effect: by use this dust-filtering gathering-device in the equipment of producing NdFeB rear-earth alloyed powder, the gas that contains a large amount of alloy powders that equipment is discharged directly contacts with absorption liquid, alloy powder in gas will be stayed in absorption liquid, gas through absorption liquid is eliminated the suspension in gas after filter screen and drying layer, can collect the alloy powder in gas, reduce material waste, reduce costs, reduce airborne dust simultaneously, improve working environment, eliminate safe hidden trouble.
Brief description of the drawings
Fig. 1 is according to the structural representation of dust-filtering gathering-device of the present invention.
Main description of reference numerals:

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of detailed description of the invention.
Unless separately there is other clearly to represent, otherwise in whole description and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or part, and do not get rid of other element or other part.
As shown in Figure 1, according to a kind of dust-filtering gathering-device of the specific embodiment of the invention, it is for producing the equipment of NdFeB rear-earth alloyed powder, equipment has air bleeding valve, this dust-filtering gathering-device mainly comprises container 2, filter screen 3 and air inlet pipe 1, in container 2, absorption liquid is housed, the inner chamber of container 2 is divided into filter chamber 21 and discharge chamber 22 by absorption liquid, and the discharge chamber part of container 2 is provided with exhaust outlet 5.Filter screen 3 is laid on the liquid level of the absorption liquid in container 2.One end of air inlet pipe 1 is used for connecting with air bleeding valve, and air inlet pipe 1 is through container 2 and stretch into absorption liquid inside.
As a kind of preferred embodiment, be provided with drying layer 4 at the upper surface of filter screen 3, the gas through absorption liquid is dried.
In such scheme, air inlet pipe 1 stretches into the inner setting of absorption liquid through the discharge chamber portion of container 2.
In the time of concrete this dust-filtering gathering-device of use, air inlet pipe 1 is connected with the electromagnetic exhaust valve of the equipment of producing NdFeB rear-earth alloyed powder, such as intermediate crusher, the gas that contains a large amount of alloy powders of discharging via air bleeding valve enters in container 2 by air inlet pipe 1, directly contact with absorption liquid, alloy powder in gas will be stayed in absorption liquid, gas through absorption liquid is eliminated the suspension in gas after filter screen 3 and drying layer 4, finally, collect at discharge chamber 22 through filtration and dry gas, finally enter in air by exhaust outlet 5.Can collect like this alloy powder in gas, reduce material waste, reduce costs, reduce airborne dust simultaneously, improve working environment, eliminate safe hidden trouble.
The aforementioned description to concrete exemplary of the present invention is in order to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.Exemplary embodiment is selected and the object described is to explain certain principles of the present invention and practical application thereof, thereby made those skilled in the art can realize and utilize various exemplary of the present invention and various selection and change.Scope of the present invention is intended to be limited by claims and equivalents thereof.
