[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are illustrated in the accompanying drawings, wherein identical or similar reference numerals throughout represent identical or similar elements or elements having identical or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and intended only to explain the present invention and are not to be construed as limiting the present invention. Example 1

[0030] Figure 1- Figure 3As shown, this embodiment provides a classification screen for the production of graphite-doped high-conductivity self-baking electrode paste, including a screening bin 2, a horizontally arranged crushing plate 10 fixedly connected to the screening bin 2, a vertically movable hammer head 9 slidably connected inside the screening bin 2, and a primary screen 11 connected to the crushing plate 10.

[0031] The primary screen 11 is arranged in the middle of the crushing plate 10 for screening materials. The primary screen 11 can be detachably connected to the crushing plate 10 by bolts. The primary screen 11 of different apertures can be replaced according to actual use needs.

[0032] The hammer head 9 is located above the crushing plate 10. The upper surface of the crushing plate 10 is a solid plate, which makes it easier for the hammer head 9 and the crushing plate 10 to come into contact and crush the material. The bottom end of the hammer head 9 is connected to a number of protrusions that are spaced apart to improve the crushing quality of the material.

[0033] Hammer 9 is positioned to one side of primary screen 11, so its fall does not affect it. Primary screen 11 is connected to a vibrator 14, which vibrates primary screen 11, facilitating material screening. The working portion of vibrator 14 is a rod-shaped hollow cylinder with an eccentric vibrator installed inside. Driven by an electric motor, it rotates at high speed, generating high-frequency, low-amplitude vibrations.

[0034] The crushing plate 10 is slidably connected to a guide frame 15 for receiving materials. The upper and lower ends of the guide frame 15 are open structures. A slide rail can be fixedly connected to the crushing plate 10. The slide rail and the guide frame 15 are slidably connected to ensure that the guide frame 15 can only slide in the horizontal direction. The opening at the upper end of the guide frame 15 is used for feeding, and the opening at the lower end is used for discharging. The size of the guide frame 15 is adapted to the primary screen 11, thereby facilitating discharging.

[0035] During crushing, the hammer head 9 can directly act on the crushing plate 10, and as the guide frame 15 moves, when it moves to the position of the primary screen 11, the material can be screened, so that crushing and screening are independent of each other, effectively simplifying the overall structure, facilitating overall operation control, and reducing the overall cost of the device.

[0036] The upper end of the screening bin 2 is connected to the feeding bin 1, which is arranged above the primary screening net 11. The feeding bin 1 is provided with a feeding port. The screening bin 2 is slidably connected to a door panel 21 that can block the feeding port. The door panel 21 can move horizontally to open or close the feeding port, thereby realizing gap discharge.

[0037] The guide frame 15 is fixedly connected with a rack 19, which drives the door panel 21 to slide through the gear set 20. The gear set 20 includes a third gear and a fourth gear that mesh with each other.

[0038] They are all rotatably connected to the screening bin 2, the third gear is meshed with the rack 19, the fourth gear is meshed with the door panel 21, and the setting of the gear set 20 enables the door panel 21 and the guide frame 15 to move in the same direction.

[0039] The above arrangement can achieve that when the guide frame 15 moves toward the direction close to the hammer head 9, the door panel 21 is driven to move in a direction that can block the feeding port. When the guide frame 15 moves to the position of the primary screen 11, the door panel 21 just opens the feeding port, and the material in the feeding bin 1 can fall into the guide frame 15, thereby realizing gap discharge.

[0040] By setting the slidable door panel 21, intermittent feeding can be achieved, so that the screening efficiency will not be affected by excessive feeding at one time. At the same time, the material in the feeding bin 1 can fall directly on the primary screen 11, and the material can be preliminarily screened first. At this time, the material that does not meet the specifications will be driven by the guide frame 15 to the crushing process, which effectively reduces the amount of crushed material required, thereby improving the efficiency and quality of crushing and facilitating the subsequent material screening work.

[0041] The screening bin 2 is fixedly connected to the vertical cylinder 6 and the slide cylinder 17. The vertical cylinder 6 is slidably connected to the hammer rod 7 that moves vertically. The slide cylinder 17 is slidably connected to the slide rod 16 that moves horizontally. The hammer rod 7 and the hammer head 9 are fixedly connected. The slide rod 16 and the guide frame 15 are fixedly connected.

[0042] The vertical cylinder 6 and the slide cylinder 17 are respectively provided to limit and guide the sliding of the hammer rod 7 and the slide rod 16. The slide rod 16 is connected to the slide cylinder 17 by a spring. Under the elastic force of the spring, the guide frame 15 can be moved to the top of the primary screen 11.

[0043] In order to facilitate the vertical movement of the hammer rod 7, the hammer rod 7 can also be connected to the vertical cylinder 6 through a return spring. Under the elastic force of the return spring, the hammer head 9 and the crushing plate 10 can be brought into contact to achieve crushing of the material. The setting of the return spring can facilitate the descent of the hammer head 9 and improve the quality of crushing.

[0044] The screening bin 2 is rotatably connected to the first gear 8 and the second gear 18. The first gear 8 is engaged with the hammer rod 7, and the second gear 18 is engaged with the slide bar 16. When the first gear 8 rotates, the hammer rod 7 is driven to rise. When the second gear 18 rotates, the guide frame 15 is driven to move toward the direction close to the hammer head 9.

[0045] The first gear 7 can drive the second gear 18 to rotate through a belt. The first gear 7 can be coaxially fixedly connected to the first pulley, and the second gear 18 can be coaxially fixedly connected to the second pulley. The first pulley and the second pulley are provided with belts. The first gear 7 is connected to a driving mechanism, and the driving mechanism can drive the first gear 7 to rotate.

[0046] The driving motor can be specifically a motor, which is fixedly connected to the screening bin 2 and is arranged on the outside of the screening bin 2. The motor can drive the first gear 7 to rotate, and then drive the second gear 18 to rotate at the same time through the belt, thereby facilitating the coordinated movement of the hammer rod 7 and the guide frame 15.

[0047] The first gear 8 and the second gear 18 are both toothless gears. When the guide frame 15 moves below the hammer head 9, the first gear 8 and the hammer rod 7 are disengaged. At this time, the hammer rod 7 drives the hammer head 9 to descend, thereby crushing the material in the guide frame 15. Example 2

[0048] Refer to Figure 1- Figure 3 The other structures are the same as those in the first embodiment, except that further screening of the material is taken into consideration in this embodiment.

[0049] The screening bin 2 is also fixedly connected to a fine screen 12 arranged in an inclined direction. The fine screen 12 is located below the primary screen 11. The fine screen 12 can further screen the material and realize the classified collection of materials of different specifications. A collection box 4 is provided on one side of the fine screen 12, and a powder box 5 is provided below the fine screen 12.

[0050] The screening bin 2 is provided with a discharge port 3 and a powder port 13. The collecting box 4 is located on one side of the discharge port 3. Materials that cannot pass through the fine screen 12 can enter the collecting box 4 through the discharge port 3. The powder box 5 is arranged below the powder port 13. Materials that can pass through the fine screen 12 can fall into the powder box 5 through the powder port 13.

[0051] Specific working process: put the material into the loading bin 1, and the material falls into the guide frame 15 through the loading port. Under the action of the vibrator 14, the primary screen 11 is vibrated. At this time, some materials that meet the requirements can fall onto the fine screen 12 through the primary screen 11. Then, the materials that can pass through the fine screen 12 can fall into the powder box 5 through the powder port 13. The materials that cannot pass through the fine screen 12 can enter the collection box 4 through the discharge port 3.

[0052] The driving mechanism drives the first gear 8 to rotate, and the first gear 8 drives the hammer rod 7 to rise. At the same time, the second gear 18 drives the guide frame 15 to move toward the direction close to the hammer head 9. When the guide frame 15 moves below the hammer head 9, the first gear 8 and the hammer rod 7 are disengaged. At this time, the hammer rod 7 drives the hammer head 9 to descend, which can realize the crushing of the material in the guide frame 15. At this time, the guide frame 15 drives the door plate 21 to move through the gear set 20, so that the feeding port is closed and no more material is discharged. The guide frame 15 and the door plate 21 move at the same speed, which is convenient for receiving materials.

[0053] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
