Description
Technical field
The utility model relates to a kind of device that oxygen is provided, particularly a kind of device that oxygen is provided in the airflow milling in the neodymium-iron-boron air stream millby pulverizing process.
Background technology
At present, it is the strongest that sintered Nd-Fe-B permanent magnetic material has become contemporary magnetic, the magnetic material that cost performance is high, it not only has the characteristics such as high magnetic energy product and coercivity, the advantage of high-energy-density is applied widely sintered Nd-Fe-B permanent magnetic material in modern industry and electronic technology simultaneously, thereby makes miniaturization, lightweight, the slimming of the equipment such as instrument and meter, electroacoustic, motor, magnetic separation magnetization become possibility.The mechanicalness of sintered NdFeB itself is fairly good, can the difform product of cutting processing.
Now, producer carries out sintered Nd-Fe-B permanent magnetic material generally adopting the airflow milling powder technology in the technical process of powder process, and gas is compressed, and the supersonic airstream that forms by inside collides raw material mutually, and raw meal is broken into fine powder.In the process of neodymium-iron-boron air stream powder-grinding, usually in airflow milling, be filled with outside the nitrogen of lot of pure, also need to carry the oxygen of trace, make the oxygen content in the airflow milling reach 80PPM ~ 90PPM, the general method that adopts of the oxygen of required trace provides the oxygen that an oxygen cylinder is carried certain content in the airflow milling, the weak point of its existence is: the oxygen content in the oxygen cylinder is limited, need frequent replacing, and the weight of oxygen cylinder itself is larger, it is very inconvenient when carrying is replaced, easily the staff is damaged, affect operating efficiency, work safety is had certain impact; On the other hand, in the neodymium-iron-boron air stream millby pulverizing process, need only the quality that guarantees gas clean, dry, and less demanding to oxygen content, therefore airborne oxygen just can satisfy in the neodymium-iron-boron air stream millby pulverizing process demand to trace oxygen, and treated air quality can reach cleaning, dry requirement.
The utility model content
Technical problem to be solved in the utility model is: a kind of device that oxygen is provided in the airflow milling in the neodymium-iron-boron air stream millby pulverizing process is provided, and this device can guarantee the requirement that oxygen is dry, clean, and the staff is simple to operate, safety.
In order to solve the problems of the technologies described above, the utility model specifically is achieved through the following technical solutions: a kind of device that oxygen is provided in the airflow milling in the neodymium-iron-boron air stream millby pulverizing process, it comprises air compressor, voltage-stablizer, air cleaner, automatic water trap, described air compressor is communicated with voltage-stablizer, air cleaner and airflow milling by the air hose order, described automatic water trap is installed on the air cleaner below, and is communicated with air cleaner.
After adopting said structure, the advantage that the utility model has is: use the apparatus of oxygen supply that is comprised of air compressor, air cleaner, voltage-stablizer not need to repeat to change oxygen cylinder, only need open air compressor just can provide required oxygen for airflow milling, can guarantee simultaneously drying, the cleaning of oxygen, and the staff is simple to operate, safety.
Described air cleaner and automatic water trap are for being threaded, collect the impurity such as the water that filters down in the air cleaner, dust by automatic water trap, connected mode is simple and convenient, and the volume of automatic water trap own is little, lightweight, so that the staff is simple to operate, safety, be convenient to unified cleaning treatment.
The quantity of described air cleaner is 2, and enough air cleaners are the impurity such as the water in the filtered air, dust fully, reaches airflow milling to cleaning gas, dry requirement.
Description of drawings
Fig. 1 provides the connection diagram of the device of oxygen in for airflow milling in the neodymium-iron-boron air stream millby pulverizing process for the utility model.
As shown in the figure, 1-air compressor, 2-voltage-stablizer, 3-air cleaner, 4-automatic water trap, 5-airflow milling
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of device that oxygen is provided in the airflow milling in the neodymium-iron-boron air stream millby pulverizing process, it comprises air compressor 1, voltage-stablizer 2, air cleaner 3, automatic water trap 4, described air compressor 1 is communicated with voltage-stablizer 2 by the air hose order, air cleaner 3 and airflow milling, described automatic water trap 4 is installed on air cleaner 3 belows, and be threaded with air cleaner 3, automatic water trap 4 is collected the water that filters down in the air cleaner 3, the impurity such as dust, because connected mode is simple and convenient, and automatic water trap 4 volumes are little, lightweight, so that the staff is simple to operate, safety is convenient to unified cleaning treatment; The quantity of described air cleaner is 2, can guarantee like this to enter airflow milling Air energy bone dry, cleaning, thus reach airflow milling to the requirement of gaseous mass.
The operation of the described device that oxygen is provided for the neodymium-iron-boron air stream millby pulverizing process is as follows: described air compressor 1 enters voltage-stablizer 2 with air compressing, air pressure when regulating voltage-stablizer 2 control air inlet, air pressure when guaranteeing air inlet reaches the requirement of 0.1MPA, and then the control air is by the amount of entering of air cleaner 3; Air enters air cleaner 3 by air hose, the model of described air cleaner 3 is JGC-1, the impurity such as the moisture in described air cleaner 3 filtered airs, dust, guarantee the drying of air, clean, automatic water trap 4 is used for collecting the impurity that air cleaner 3 filters down, and is convenient to unified cleaning; At last clean, dry air are entered airflow milling by air hose, the oxygen of required trace is provided for airflow milling.
