DETAILED DESCRIPTION

[0050] The present invention is further described in detail below through embodiments. The embodiments are only used to illustrate the present invention and do not limit the scope of the present invention.

[0051] A graphite powder impurity removal device, comprising:

[0052] The box 100 is a rectangular hollow structure, and its upper and lower ends are both open; the graphite powder enters the box 100 and then passes through the box 100 from top to bottom;

[0053] The magnetic suction component 200 is located in the box body 100; the magnetic suction component 200 is distributed in the box body 100 from top to bottom; when the graphite powder entering the box body 100 passes through the magnetic suction component 200, the iron filings in the graphite powder are adsorbed by the magnetic suction component 200, thereby achieving impurity removal of the graphite powder.

[0054] The feed assembly 300 is fixed on the upper part of the box 100, and the feed assembly 300 is connected to the box 100; the graphite powder enters the box 100 through the feed assembly 300, and when the graphite powder enters the feed assembly 300, the graphite material is dispersed by the feed assembly 300, and the dispersed graphite powder enters downward into the box 100, and the dispersed graphite powder is easily adsorbed and removed by the magnetic suction assembly 200 in the box 100. That is, the feed assembly 300, on the one hand, operates the channel for the external graphite powder to enter the box 100, and on the other hand, the feed assembly 300 allows the graphite powder to enter the box from top to bottom in a dispersed state, so as to facilitate the magnetic suction assembly 200 to adsorb and remove impurities from the graphite powder in the later stage.

[0055] The lower part of the box body 100 is connected to the collecting hopper 400. The collecting hopper 400 is a funnel-shaped structure, and a discharge port 410 is arranged at the lower part of the collecting hopper 400. The graphite powder discharged from the box body 100 is finally discharged to the outside through the collecting hopper 400.

[0056] See also Figure 4A door window 110 is provided through the front side wall of the box body 100. The door window 110 is a rectangular structure. A door cover 120 is matched with the door window 110. A retaining edge 121 is fixed on the periphery of the door cover 120. The retaining edge 121 surrounds the door cover 120. The retaining edge 121 is fixed to the box body 100 by screws (not shown in the figure).

[0057] The brackets 130 are fixed on both sides of the box body 100. The main body of the bracket 130 is in a "𠃍" shape. A seat plate 131 is arranged at the lower part of the bracket 130, and the bottom of the bracket 130 is fixed on the seat plate 131. The bracket 130 makes the box body 100 suspended in the air, and the graphite powder can enter the box body 100 from the feeding assembly 300, and then enter the collecting hopper 400 from the box body 100 and finally be discharged downward from the collecting hopper 400.

[0058] The magnetic attraction assembly 200 includes:

[0059] The upper adsorption group 210 is fixedly disposed on the inner surface of the door cover 120. There are a plurality of upper adsorption groups 210 distributed from top to bottom.

There are several lower adsorption groups 220 and they are distributed from top to bottom. The structure of the lower adsorption group 220 is consistent with that of the upper adsorption group 210. Through the arrangement of the upper adsorption group 210 and the lower adsorption group 220, when the graphite powder moves downward into the interior of the box body 100, the iron filings in the graphite powder are first adsorbed by the upper adsorption group 210, and then as the graphite powder continues to move downward, the iron filings in the graphite powder are adsorbed by the lower adsorption group 220. When the adsorption group needs to be replaced, the door cover 120 can be opened, and then the upper adsorption group 210 can be replaced, and then the lower adsorption group 220 in the box body 100 can be replaced. One end of the upper adsorption group 210 and the lower adsorption group 220 are respectively fixed to the front and rear sides of the box body 100, so that the distribution position of the adsorption group is relatively dispersed, which is conducive to installation and later replacement.

[0064] The limiting cylinder 213 is fixedly connected to the other side surface of the supporting plate 212, and the limiting cylinder 213 is a hollow cylindrical structure;

[0065] The fixing column 214 is a cylindrical structure, and its matching set is embedded in the limiting cylinder 213; when the fixing column 214 is inserted into the limiting cylinder 213, the relative positions of the fixing column 214 and the limiting cylinder 213 are fixed.

[0070] The dispersion component 320 is located in the material distribution box 310, and the main body of the dispersion component 320 can rotate in the material distribution box 310; as the dispersion component 320 rotates, the graphite powder entering the material distribution box 310 is "broken up" by the dispersion component 320, and the "broken up" graphite powder continues to move downward into the box body 100, and the iron filings in the graphite powder are adsorbed by the magnetic suction component 200.

[0076] The upper air vent 323 is arranged at the upper part of one side of the material equalizing box 310, and the outlet of the upper air vent 323 is located in the material equalizing box 310, and the outlet of the upper air vent 323 faces downward, and the outlet of the upper air vent 323 faces the blade 321; when the gas introduced from the upper air vent 323 enters the interior of the material equalizing box 310, the gas impacts the blade 321 to cause the blade 321 to rotate; the blade 321 "breaks up" the graphite powder in the material equalizing box 310 during rotation, and at the same time, the gas can also "impact" the graphite powder, which is more conducive to the dispersion of the graphite powder in the material equalizing box 310.

[0077] The lower air vent 324 is arranged at the lower part of the other side of the material equalizing box 310, and the outlet of the lower air vent 324 is located in the material equalizing box 310, and the outlet of the lower air vent 324 faces upward, and the outlet of the lower air vent 324 faces the blade 321; when the gas introduced from the lower air vent 324 enters the interior of the material equalizing box 310, the gas impacts the blade 321 to cause the blade 321 to rotate; the blade 321 "breaks up" the graphite powder in the material equalizing box 310 during rotation, and at the same time, the gas can also "impact" the graphite powder, which is more conducive to the dispersion of the graphite powder in the material equalizing box 310.

The feed box 330 has a structure that is wide at the top and narrow at the bottom, and the feed ports are located on both sides of the feed box 330, which prevents the graphite powder from diffusing outward from the feed box 330.
