Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

FIG. 1 shows a device for purifying grinding residue of hafnium boride powder, comprising a housing 1 and a grinding chamber 2 on the upper part of the housing 1, wherein the top surface of the housing 1 is provided with a feed inlet 11 leading to the grinding chamber 2, the grinding chamber 2 is internally provided with a grinding roller 3 driven by a motor, the grinding chamber 2 below the bottom of the grinding roller 3 is provided with a discharge port 4, the discharge port 4 is internally provided with a first filter screen 41, the discharge port 4 extends downwards to form a piston chamber 5, the piston chamber 5 is internally provided with a piston 51, the piston 51 is positioned below the first filter screen 41, the bottom surface of the piston chamber 5 is connected with a push rod of a push rod motor 6, the push rod of the push rod motor 6 passes through the lower end of the piston chamber 5, the push rod motor 6 is arranged below the piston chamber 5, the right side of the lower part of the piston chamber 5 is provided with an output port, the right lower end of the second filter screen 7 is connected with a filter residue collecting chamber 9.

Because piston 51 is under push rod motor 6's control, be straight reciprocating motion in piston chamber 5, filter out from first filter screen 41 after grinding hafnium boride powder with higher speed, because the influence of suction and power of spouting, hafnium boride powder is difficult for the adhesion on first filter screen 41 and grinding roller 3, when piston 51 descends, hafnium boride powder can fall into second filter screen 7 through the delivery outlet of piston chamber 5, hafnium boride powder that the particle size is little will fall into its below from second filter screen 7 and collect room 8, the filter residue that the particle size is big will fall into filter residue collection room 9 along the inclined plane of second filter screen.

The upper surface of the piston 51 is an inclined surface forming an angle with the horizontal plane, and the part of the inclined surface close to the output port 52 is lower than the part far from the output port 52.

Since the upper surface of the piston 51 is provided with a slope inclined toward the output port 52, it is facilitated that the powder passing through the first sieve 41 falls toward the output port 52 and out of the output port 52.

The angle of inclination of the second screen 7 coincides with the angle of inclination of the upper surface of the piston 51.

Because the inclination angle of second filter screen 7 is unanimous with the inclination of piston 51 upper surface, more be favorable to the hafnium boride powder to fall into second filter screen 7 smoothly, can not change because of the landing angle, and the adhesion is in the contained angle.

The angle of inclination of the second screen 7 and the angle of inclination of the upper surface of the piston 51 are 30 degrees.

The preferred inclination angle is 30 degrees, and the landing speed of hafnium boride powder is moderate, is favorable to abundant second filter screen 7's filter area, improves filtration efficiency.
