[0011] Reference Figures 1-4 The aforementioned screening and demagnetizing device for preparing graphite anode materials is characterized by comprising: a fixed base 1 and an oscillating host 2 connected to the middle of the right side of the upper surface of the fixed base 1; a screening outer box 3 connected to the middle of the upper surface of the oscillating host 2; a screening device 4 movably inserted into the middle of the interior of the screening outer box 3; a cleaning device 5 connected to the middle of the right edge of the lower surface of the screening device 4; a movable baffle 6 inserted into the middle of the upper edge of the left side surface of the screening outer box 3; and the middle of the left edge of the lower surface of the screening outer box 3 being aligned with the upper surface of the fixed base 1. A movable support plate 7 is connected between the middle of the left edge of the outer screening box 3. The outer screening box 3 includes a box body 3-1, a locking block 3-2, an insertion hole 3-3, and a notch 3-4. The locking blocks 3-2 are symmetrically connected to the middle of the front and rear edges of the left and right surfaces inside the box body 3-1. Each locking block 3-2 has an insertion hole 3-3 in the middle of its upper surface. A notch 3-4 is provided in the middle of the upper edge of the left side of the box body 3-1. The movable baffle 6 is inserted into the notch 3-4, and the lower surface of the movable baffle 6 is connected to the lower surface of the notch 3-4 by a hinge. Next, a discharge port is provided at the lower center of the left side surface of the box 3-1. An adsorption plate is inserted into the lower surface of the inside of the box 3-1. The screening device 4 includes an outer frame 4-1, insert posts 4-2, rubber rings 4-3, and a screen 4-4. Insert posts 4-2 are connected to the four corners of the lower surface of the outer frame 4-1. Several rubber rings 4-3 are evenly distributed vertically on the side surface of each insert post 4-2. A screen 4-4 is inserted into the middle of the upper surface of the outer frame 4-1. The insert posts 4-2 are inserted into the insertion holes 3-3. The outer frame 4-1 is secured. On the upper surface of the card block 3-2, the cleaning device 5 includes a scraper 5-1, a rodless cylinder 5-2, a cross column 5-3, and a support plate 5-4. The rodless cylinder 5-2 is symmetrically connected to the middle of the upper edge of the front and rear surfaces of the scraper 5-1. The cross column 5-3 is inserted through the middle of the left side surface of each of the rodless cylinders 5-2. The support plate 5-4 is symmetrically connected to the center of the left and right side surfaces of the cross column 5-3. The upper surface of the support plate 5-4 is connected to the lower surface of the outer frame 4-1. The lower surface of the scraper 5-1 is in contact with the lower inner surface of the housing 3-1.

[0012] In use, the operator first inserts the outer frame 4-1 of the screening device 4 into the box 3-1 of the screening box 3. Simultaneously, the insert post 4-2 is inserted into the insertion hole 3-3, and the rubber ring 4-3 increases the friction between the insert post 4-2 and the insertion hole 3-3 to prevent the outer frame 4-1 from moving. The outer frame 4-1 is also secured to the upper surface of the locking block 3-2. Then, the operator evenly places the graphite on the screen 4-4 and starts the vibrating host 2 to cause the box 3-1 to vibrate, allowing the magnetic material inside the graphite to be filtered through the screen 4-4 to the bottom of the box 3-1. At the same time, because the bottom of the box 3-1 has an adsorption plate, the magnetic material is absorbed by the screen. The magnetic material is adsorbed onto the bottom of the box 3-1, while the box 3-1 rotates on the movable display plate 7. After screening, the movable baffle 6 is rotated to open the opening 3-4. At the same time, the movable baffle 6 is locked onto the left side surface of the box 3-1. Simultaneously, the screened graphite is discharged through the movable baffle 6. Finally, the operator activates the rodless cylinder 5-2 on the cleaning device 5, causing the rodless cylinder 5-2 to slide on the horizontal column 5-3. At the same time, the two rodless cylinders 5-2 drive the scraper 5-1 to move, scraping off the magnetic material on the adsorption plate and discharging it through the discharge port on the box 3-1.
