[0023] See also Figures 1-4 As shown, the utility model provides a technical solution:

[0024] A graphite grading, screening and separation device comprises a screening mechanism 101, a separation mechanism 102 and a support mechanism 103, wherein the separation mechanism 102 is located on the left side of the screening mechanism 101, and the support mechanism 103 is located at the bottom end of the screening mechanism 101; the screening mechanism 101 comprises a screening barrel 104, a feed pipe 105 is fixedly mounted on the lower right end of the screening barrel 104, a tee pipe 106 is fixedly mounted on the top end of the screening barrel 104, and a discharge pipe 201 is fixedly mounted on the left end of the tee pipe 106.

[0025] Through the above solution, graphite powder can be screened through the screening barrel, the storage device can be connected and the feeding can be completed through the feed pipe, and the discharge pipe and the drive machine can be installed through the three-way pipe.

[0026] In this embodiment, preferably, the separation mechanism 102 further includes a driving machine 202, which is fixedly mounted on the top of the tee pipe 106, a driving shaft 203 is fixedly mounted on the bottom of the driving machine 202, and a rotating screening net 204 is fixedly mounted on the bottom of the driving shaft 203.

[0027] According to the above solution, the driving shaft is driven to rotate by the driving motor, so that the rotating screening net can be rotated and screened inside the screening barrel.

[0028] In this embodiment, preferably, the rotating screening net 204 is movably installed inside the screening barrel 104, a large screen plate 205 and a small screen plate 206 are fixedly installed on the lower side of the screening barrel 104, and a lower hopper 301 is fixedly installed at the bottom end of the screening barrel 104.

[0029] Through the above scheme, the graphite powder is double-graded and screened by the large sieve plate and the small sieve plate. The double screening can reduce the screening pressure of the large sieve plate and the small sieve plate respectively to avoid the sieve plate being blocked by the graphite powder, and the graphite powder that does not meet the standards can be discharged through the lower hopper.

[0030] In this embodiment, preferably, the separation mechanism 102 includes a separation box 302, a discharge pipe 201 is fixedly installed on the lower right end of the separation box 302, a box cover 303 is fixedly installed on the top of the separation box 302, and an induced draft fan 305 is fixedly installed in the middle of the top of the box cover 303.

[0031] Through the above scheme, the qualified graphite powder can be discharged into the separation box through the discharge pipe, the interior of the separation box can be easily repaired and cleaned through the box cover, and air flow can be generated inside the separation box and the screening barrel through suction by the induced draft fan.

[0032] In this embodiment, preferably, a discharge hopper 306 is fixedly installed at the bottom end of the separation box 302, a spiral conveying pipe 401 is fixedly installed at the front end of the discharge hopper 306, and a rotating machine 402 is fixedly installed at the front end of the spiral conveying pipe 401.

[0033] Through the above scheme, the separated graphite powder can be stored and discharged through the discharge hopper, and the spiral conveying pipe is driven by the rotation of the rotating machine. The spiral conveying pipe has built-in conveying blades, and its rotation can convey the graphite powder in the discharge hopper to the weighing meter.

[0034] In this embodiment, preferably, a weighing meter 403 is fixedly installed at the bottom end of the spiral conveying tube 401, a sensing valve 404 is fixedly installed at the front end of the weighing meter 403, and a discharge pipe 405 is fixedly installed at the bottom end of the weighing meter 403.

[0035] Through the above scheme, the conveyed graphite powder can be weighed and measured by the weighing meter. When the set measuring range is reached, a signal is sent to control the rotating machine to drive the spiral conveying pipe to stop conveying. At the same time, the sensing valve opens after receiving the standard signal, allowing the graphite powder to be discharged from the discharge pipe, completing the quantitative discharge.

[0036] In this embodiment, preferably, the support mechanism 103 includes a support platform 406, the top of which is fixedly mounted with a screening barrel 104 and a separation box 302, the bottom of which is fixedly mounted with a support leg 501, and the middle of which is fixedly mounted with a support frame 502.

[0037] Through the above solution, the screening barrel and the separation box can be supported by the support platform, the support platform can be supported by the support legs, and the support can be made more stable by the support frame.

[0038] When using a graphite grading, screening and separation device of this embodiment, the user connects the feed pipe 105 and the storage device, and then starts the induced draft fan 305 to generate airflow in the separation box 302 and the screening barrel 104, so that the graphite powder in the storage device is driven by the airflow to pass through the feed pipe 105 into the screening barrel 104, and the large screen plate 205 and the small screen plate 206 in the screening barrel 104 perform double-grading screening on the graphite powder. The double screening can reduce the screening pressure of the large screen plate 205 and the small screen plate 206 respectively to prevent the graphite powder from clogging the screen plate, and the large-particle graphite powder screened out falls into the lower hopper 301 by gravity and is discharged. Then the screened graphite powder enters the rotating screening net 204 through the airflow. At this time, the driving motor 202 drives the driving shaft 203 to rotate, causing the rotating screening net 204 to rotate, and the graphite powder that does not meet the standards is screened out again and is rotated and thrown out to pass through the small screen plate 206 and the large screen by gravity. The plate 205 falls into the discharge hopper 301 and is discharged, and the graphite powder that meets the standards is driven by the air flow through the rotating screening net 204 and enters the separation box 302 through the discharge pipe 201. The separation box 302 has a built-in ultrafine powder filter bag to filter out the entered graphite powder to achieve gas-powder separation. The separated gas is discharged through the induced draft fan 305, and the filtered graphite powder enters the discharge hopper 306. At this time, the rotating machine 402 rotates to drive the spiral conveying pipe 401 to work. The spiral conveying pipe 401 has built-in conveying blades, which rotate to convey the graphite powder in the discharge hopper 306 to the weighing meter 403. The weighing meter 403 has a measuring range set manually. When the weighing meets the standard, the weighing meter 403 sends a signal to control the rotating machine 402 to drive the spiral conveying pipe 401 to stop conveying. At the same time, the sensing valve 404 opens after receiving the standard signal, so that the graphite powder is discharged from the discharge pipe 405, completing the quantitative discharge.
