Description
Technical field
The utility model relates to a kind of sintered NdFeB powder screening plant.
Background technology
Sintered neodymium iron boron material, as the important basic functional material of a class, have excellent magnetic property, but its intensity is low, poor toughness.This not only makes such material mechanical processing difficulties, affects product qualified rate, and also limit the further expansion of its application.Sintered neodymium iron boron material is a kind of fragile material, and toughness plasticity is poor, although NdFeB material can carry out cutting and holing, its difficulty of processing is larger, and machining accuracy is lower, and yield rate is relatively low, meanwhile, in transport assembling process, easily knocks limit, arrisdefect.Anti-vibration impact resistance is poor.The density of material is the key factor affecting toughness of material, and the density of sintered neodymium iron boron material depends on material initial powder granularity to a great extent.So screening sintered NdFeB powder is committed step, at present, the screen cloth generally by arranging certain order number screens sintered NdFeB powder, be separated thickness powder, fines collection is stand-by, and meal will recycle separately, then cause stock utilization low, complex technical process, lost labor.
Utility model content
The purpose of this utility model is to overcome above deficiency, a kind of sintered NdFeB powder screening plant is provided, the utility model adopts vibration screening to prevent sintered NdFeB powder from reuniting, screen again after again process being ground to isolated meal, improve stock utilization, technical process is integrated, simple and easy to control, saves artificial.
The technical scheme that the utility model provides is:
A kind of sintered NdFeB powder screening plant, comprising:
Feeding chamber, it is infundibulate, and described feeding chamber inwall is coated with the antirust wearing layer of one deck 20-50 μm;
Separation chamber, it comprises fine powder outlet and meal outlet, and top, described separation chamber communicates with bottom described feeding chamber, is provided with cyclone separator in described separation chamber;
Meal grinding chamber, its one end exports with described meal and communicates, and one end communicates with feeding chamber in addition, is provided with air flow milling nozzle, described air flow milling nozzle is provided with ball plug bottom described coarse fodder grinding chamber;
Fines collection room, is provided with vibratory sieve between itself and described fine powder export, described vibratory sieve is provided with screen cloth, described vibratory sieve is provided with vibrating sensor
Preferably, in described sintered NdFeB powder screening plant, described antirust wearing layer is the chromium adopting electro-plating method deposition.
Preferably, described sintered NdFeB powder screening plant, also comprise grading wheel, it is connected with cyclone separator.
Preferably, in described sintered NdFeB powder screening plant, described meal grinding chamber is airflow milling grinding chamber.
Preferably, in described sintered NdFeB powder screening plant, the pipeline that described meal grinding chamber and described feeding chamber communicate is provided with control valve.
Preferably, in described sintered NdFeB powder screening plant, in described meal grinding chamber, vibrator is provided with.
Preferably, in described sintered NdFeB powder screening plant, the sieve number of described vibratory sieve is 15-30 order.
The beneficial effects of the utility model are, the utility model adopts vibration screening to prevent sintered NdFeB powder from reuniting, and screens after grinding process again to isolated meal again, improve stock utilization, technical process is integrated, simple and easy to control, saves artificial.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
As shown in Figure 1, the utility model provides a kind of sintered NdFeB powder screening plant, comprising:
Feeding chamber 1, feeding chamber is funnel type, and feeding chamber inwall is coated with the antirust wearing layer of one deck 20-50 μm, and antirust wearing layer is the chromium adopting electro-plating method deposition; Separation chamber 2, it comprises fine powder outlet 3 and meal outlet 4, and top, separation chamber 2 communicates with bottom feeding chamber 1, is provided with cyclone separator 5 in separation chamber 2, is provided with grading wheel 6, is connected with cyclone separator 5; Meal grinding chamber 7, its one end and meal export 4 and communicate, one end communicates with feeding chamber 1 in addition, meal grinding chamber 7 is airflow milling grinding chamber, vibrator 11 is provided with in meal grinding chamber, be provided with air flow milling nozzle 12 bottom coarse fodder grinding chamber, air flow milling nozzle is provided with ball plug, the pipeline that meal grinding chamber and feeding chamber communicate is provided with control valve 10; Fines collection room 9, is provided with vibratory sieve 8 between itself and fine powder export, vibratory sieve is provided with vibrating sensor, and the sieve number of vibratory sieve is 15-30 order;
When adopting the utility model to screen sintered NdFeB powder, by feeding chamber 1, sintered NdFeB powder is joined 2 li, separation chamber, powder is under the effect of the cyclone separator 5 driven by grading wheel 6, powder is divided into thickness powder, fine powder screens through vibratory sieve 8 through fine powder outlet 3, entering fines collection room 9 collects stand-by, meal enters meal grinding chamber 7 through meal outlet 4, under the air-flow entered by meal grinding chamber bottom airflow mill nozzle 12 and vibrator 11 are acted on, mutual collision grinds to form comparatively fine powder, after having ground, opening controlling valve 10, make the powder after grinding reenter feeding chamber to screen.
