Detailed implementation manner

[0019] In the following, the present utility model will be described in detail with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0020] As Figures 1 to 5 In an embodiment of the screening device for the production of graphite products of the present utility model as shown, a vibration motor 11 for driving the vibration thereof, a feed inlet 12 for feeding materials, and a discharge outlet 13 for discharging materials are provided on the body 1. A plurality of screens 21 arranged at intervals and a cleaning device 3 for cleaning a plurality of screens 21 are provided on the body 1; the cleaning device 3 includes a driving motor 31, a rotating shaft 32 fixed on the output shaft of the driving motor 31, and a plurality of cleaning members 33 arranged at intervals on the rotating shaft 32 and capable of cleaning the upper and lower surfaces of the screen 21 simultaneously; a plurality of openable and closable material discharge ports 14 are provided on the side wall of the body 1. By designing a cleaning member for cleaning the upper and lower surfaces of the screen simultaneously to scrape and filter and clean the screen, and cooperating with a plurality of material discharge ports for discharging materials layer by layer, the risk of graphite clogging the screen holes and affecting the screening efficiency is effectively reduced, the service time of the equipment is increased, and the cleaning frequency and cost are reduced.

[0021] Specifically, the cleaning member 33 includes a cleaning brush 331 for cleaning the lower surface of the screen 21 and a scraping filter 332 for cleaning the upper surface of the screen 21; the scraping filter 332 includes a scraping plate 333 closely attached to the upper surface of the screen 21.

[0022] Specifically, the vertical cross-section of the scraping plate 333 gradually shrinks along the cleaning rotation direction of the rotating shaft 32; bristles in contact with the screen 21 are provided on the scraping plate 333. By designing a scraping plate with a variable thickness, the separation, lifting and scattering of materials during the screening process are realized, the screening efficiency is improved, and the retained materials after screening are quickly pushed and collected by reverse rotation, ensuring the collection efficiency.

[0023] Specifically, the screen 21 includes two screen frames 23 that can be pulled and inserted into the body 1 in opposite directions; a support frame 22 for supporting the sliding of the screen frame 23 is provided inside the body 1; a plurality of mounting openings 18 for the screen frame 23 to enter and exit are provided on the side wall of the body 1. By designing two screen frames that can be pulled in opposite directions to form a screen, the disassembly efficiency of the screen is effectively improved, and it is convenient to clean and replace the screen.

[0024] Specifically, a reinforcing support wall is provided on the side wall between the two mounting openings 18 of the machine body 1.

[0025] Specifically, a plurality of guide sleeves 16 arranged at intervals are provided in the machine body 1; the guide sleeves 16 are fixed to the side wall of the machine body 1 through the support plates 17; the guide sleeves 16 are sleeved on the outer periphery of the rotating shaft 32.

[0026] Specifically, a collecting hopper 15 is provided at the bottom of the machine body 1; the bottom plate of the collecting hopper 15 is inclined downward along the direction close to the discharge port 13.

[0027] Working principle: The conveying device conveys the graphite material into the feed port 12. The graphite is screened through the screen 21 under the vibration of the vibration motor 11. The driving motor 31 drives a plurality of cleaning members 33 through the rotating shaft 32 to clean each stage of the screen 21. The scraping filter 332 scrapes and filters the upper surface of the screen 21 during rotation. The scraping plate 333 pushes the graphite to fall after turning over from its upper surface during rotation, reducing the risk of graphite accumulation and blockage of the screen holes. Moreover, the rotating cleaning brush 331 cleans the lower surface of the screen 21. During rotation, the bristles are inserted into the screen holes to poke and scrape the materials in the screen holes, further reducing the risk of screen hole blockage, increasing the service life of the screen 21, and reducing the cleaning frequency and cost of the screen 21. After using for a period of time, the sealing door of the discharge port 14 is opened, and the materials remaining on the screen 21 are pushed out for collection under the scraping and filtering action of the scraping plate 333. After cleaning, the sealing door is closed again for subsequent screening work. After using for a period of time, the screen frame 23 can be directly pulled out from the mounting opening 18 for external cleaning or replacement, effectively increasing the service time of the screening device and reducing the maintenance frequency.
