Description

Technical Field

[0001] The utility model belongs to the technical field of conductive graphite powder processing, in particular to an impurity removal device for graphite processing. Background Art

[0002] In the process of removing impurities from conductive graphite powder, a vibrating screening machine is required. For example, patent application No. 202320459089.2 discloses a conductive graphite powder impurity removal device, including a screening machine body, a feed port, a connecting block, and a feed hopper, etc. By setting the screening machine body, the connecting block, the feed hopper, the connecting pipe, the first spring bar and the second spring bar, the user puts the conductive graphite powder into the feed hopper, and by pulling the pull ring forward and releasing it, a force is generated between the first spring bar and the second spring bar to drive the connecting pipe to move forward and backward, so that the feed hopper is constantly shaken. The conductive graphite powder retained in the inner wall of the feed hopper can be shaken down, so as to improve the efficiency of the conductive graphite powder entering the main body of the screening machine. The connection relationship among the feed hopper, the card slot, the baffle and the card block is set, and the bottom of the plug block is inserted into the socket by pressing the adjusting block inward. The pressed adjusting block is released so that the third spring bar pushes the card block into the card slot, so as to limit the baffle at the top of the feed hopper, avoid dust and other impurities adhering to the inner wall of the feed hopper, and prevent dust and other impurities from mixing into the conductive graphite powder, which is beneficial to improve the impurity removal efficiency of the conductive graphite powder.

[0003] The above disclosed technical solution has the following defects during use: first, when the hopper is shaken, only in the initial stage after the spring is deformed, will the connecting pipe collide with the connecting block, causing a vibration, which will shake the graphite powder in the hopper down; subsequently, affected by the friction force, the spring can only drive the hopper to shake slightly, and cannot continue to collide to produce a vibration, resulting in the graphite powder being unable to be vibrated multiple times, making it inconvenient for the graphite powder to separate from the inner wall of the hopper, reducing the effect of the graphite powder falling; secondly, when the baffle is used for dust prevention, before and after placing the graphite powder in the hopper, the baffle needs to be moved back and forth to open and close, and the baffle needs to be limited and fixed again, resulting in a more complicated operation process and inconvenient use. Utility Model Content

The graphite powder attached to the hopper is vibrated multiple times through a shaking mechanism, which makes it easier for the graphite powder to separate from the inner wall of the hopper and improves the effect of the graphite powder falling. The dustproof mechanism avoids the process of moving the baffle back and forth and additionally fixing it, thereby simplifying the operation process and making it more convenient to use.

Example

[0020] See attached Figure 1-3 As shown, a graphite processing impurity removal device comprises a screening machine body 1, a hopper 2 is arranged above the screening machine body 1, a connecting block 3 is fixedly connected to the top of the screening machine body 1, a feeding port located inside the connecting block 3 is opened on the top of the screening machine body 1, the hopper 2 is located above the connecting block 3, an opening is arranged on the top of the hopper 2, a connecting pipe 4 located inside the connecting block 3 is connected to the bottom of the hopper 2, a hose 5 is connected to the feeding port of the screening machine body 1, and the top of the hose 5 is connected to the connecting pipe 4, a shaking mechanism is arranged above the screening machine body 1, and a dust prevention mechanism is arranged in the hopper 2;

[0021] Rocking mechanism: Both sides of the connecting pipe 4 are fixedly connected with movable rods 6, and the ends of the movable rods 6 away from the connecting pipe 4 penetrate to the outside of the connecting block 3. A spring 7 is sleeved on the left movable rod 6, and the left end of the spring 7 is fixedly connected to the inner wall of the connecting block 3, and the right end of the spring 7 is fixedly connected to the outer wall of the connecting pipe 4. The right end of the right movable rod 6 is fixedly connected with a movable plate 8. The top of the screening machine body 1 is rotatably connected with a rotating shaft 9, and the top of the rotating shaft 9 is fixedly connected with a cam 10 corresponding to the movable plate 8. The top of the screening machine body 1 is fixedly connected with a slide groove 11 located on the right side of the rotating shaft 9, and a rack 12 is slidably connected in the slide groove 11. A gear 13 meshing with the rack 12 is fixedly sleeved on the rotating shaft 9, and a convex block 14 corresponding to the connecting pipe 4 is fixedly connected to the right side of the inner wall of the connecting block 3;

[0022] Dust-proof mechanism: baffles 15 are hinged on the left and right sides of the inner wall of the hopper 2, and the adjacent sides of the two baffles 15 fit each other. The top of the baffle 15 is fixedly connected with a spring 2 16, and the top of the spring 2 16 is fixedly connected to the top of the inner wall of the hopper 2. The top of the inner wall of the hopper 2 is fixedly connected with an electromagnet 17 located above the baffle 15, and an iron block 19 corresponding to the electromagnet 17 is fixedly embedded on the upper surface of the baffle 15.

[0023] A spring three 18 is fixedly connected in the slide groove 11, and the end of the spring three 18 is fixedly connected to the rack 12. The spring three 18 can be a spring with a spring coefficient much larger than that of the spring one 7, so as to drive the rack 12 to reset.

[0024] A plurality of balls 20 are movably embedded in the top of the connecting block 3 , and the balls 20 roll as the hopper 2 shakes.

[0025] Working principle: In the present utility model, it should be noted that the electromagnet 17 is electrically connected to the power supply on the device by a wire. When the device is powered on and off, the electromagnet 17 is also powered on and off accordingly. The specific connection method of the wire is an existing public technology and will not be described in detail here. When the conductive graphite powder is placed, the two baffles 15 are pressed downward, and the two baffles 15 rotate downward and move away from each other. The baffle 15 pulls the spring 2 16 to extend. At this time, the graphite powder can be placed in the feed hopper 2. After placing, it is released, and the spring 2 16 drives the baffle 15 to reset. The two baffles 15 are reset to a horizontal state that fits each other. At this time, the two baffles 15 prevent dust and other impurities from contacting the graphite powder in the hopper 2. When the graphite powder feed falls, the rack 12 is pulled, and the rack 12 drives the gear 13 to rotate. The gear 13 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the cam 10 to rotate. When the raised part of the cam 10 rotates to the left, the cam 10 pushes the movable plate 8 to move to the left. Plate 8 drives the right movable rod 6 to move, the right movable rod 6 drives the connecting pipe 4 to move, the connecting pipe 4 drives the hopper 2 to move and squeezes the spring 17. When the raised part of the cam 10 rotates to the right, the spring 17 pushes the connecting pipe 4 to return to the right. When the connecting pipe 4 moves to the right, it collides with the protrusion 14 to produce a vibration. The hopper 2 vibrates along with the connecting pipe 4. Then, as the rack 12 is pulled, the hopper 2 vibrates many times. The graphite powder attached to the hopper 2 is vibrated many times, and the graphite powder attached to the hopper 2 is vibrated many times. The graphite powder is shaken off, and the spring three 18 stretches with the movement of the rack 12. When the rack 12 is released, the rack 12 is reset along the slide groove 11. In this process, the gear 13 is driven to rotate in the opposite direction. Similarly, the hopper 2 is shaken multiple times again, and the graphite powder passes through the connecting pipe 4 from the hopper 2 and enters the screening machine body 1 after passing through the hose 5. When the screening machine body 1 is powered on to remove impurities, the electromagnet 17 is powered on to generate suction, which firmly adsorbs the iron block 19 and keeps the baffle 15 in place.
