Description

Technical Field

[0001] The invention relates to the technical field of screen materials for graphite electrode production, in particular to a novel screen material mechanism for graphite electrode roasting production. Background Art

[0002] In the graphite electrode roasting production process, the screening mechanism is a key equipment to ensure the uniformity of raw material particles and production efficiency. The common screening mechanism structure in the existing technology often uses a vibrating screen for particle classification and cooperates with a screw conveyor to achieve continuous material transportation.

[0003] The existing technology uses a motor to drive a pulley to drive the filter plate to vibrate, and uses multiple layers of screens to grade and screen raw materials of different particle sizes;

[0004] However, when the above-mentioned prior art structure is used in the screening process, the particles are easily accumulated and agglomerated, and are blocked by the first screening plate. The particles are then sent to the second screening plate for screening again. However, the agglomerated particles are scattered during transportation, resulting in uneven particle sizes screened in the second screening plate, which ultimately leads to large differences in raw materials between tanks and affects the stability of subsequent processes.

DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below with reference to the accompanying drawings.

[0031] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 : A new type of screening mechanism for graphite electrode roasting production, which includes a bottom support frame 1, the upper part of the bottom support frame 1 is slidably connected to a first support frame 2 and a second support frame 3, a material receiving hopper 9 is fixedly installed on the second support frame 3, a triangular support frame 10 is provided on the first support frame 2, and a vibrating screen power assembly 4 is provided between the first support frame 2 and the second support frame 3;

[0032] The bottom support frame 1 includes a bottom support frame body 101, and two symmetrically distributed upper through slots 103 are provided on the top of the bottom support frame body 101, and two symmetrically distributed side through slots 102 are provided on both sides of the bottom support frame body 101. The first support frame 2 includes a slide 201 that can move left and right in the upper through slot 103 and the side through slot 102, and the second support frame 3 includes a driving slide 301 that can move left and right in the upper through slot 103 and the side through slot 102. A rotating shaft 203 is provided at both ends of the slide 201, and a dual-axis drive motor 303 is provided in the driving slide 301. The output shaft of the dual-axis drive motor 303 is exposed to the driving slide 301, and the driving slide 301 realizes the movement of the slide 201 through the vibrating screen power assembly 4, thereby providing power to the screen 7;

[0033] The vibrating screen power assembly 4 includes a swing arm 401 fixedly connected to the two output shafts of the dual-axis drive motor 303, and the end of the swing arm 401 away from the dual-axis drive motor 303 is rotatably connected to a connecting rod 402, and the end of the connecting rod 402 away from the swing arm 401 is rotatably connected to the rotating shaft 203, a first spring 204 is provided on both sides of the slide 201, and a second spring 304 is provided on both sides of the driving slide 301.

[0034] Through the above structure, the dual-axis drive motor 303 is started, and the output shaft of the dual-axis drive motor 303 drives the swing arms 401 at both ends to rotate, so that the connecting rod 402 swings with the rotating shaft 203 as the axis. During the swinging process, the horizontal distance between the slide 201 and the driving slide 301 changes continuously. During this process, the first spring 204 and the second spring 304 provide vibration due to compression, causing the upper material receiving hopper 9 and the screen 7 to vibrate, thereby achieving the effect of vibrating the screen.

[0035] Combined with attachment Figure 2 , Attachment Figure 3 and attached Figure 4 :

[0036] Frequency modulation devices 5 for adjusting the vibration frequency of the vibration power assembly 4 are provided on both sides of the bottom support frame 1. The frequency modulation device 5 includes top plates 504 respectively located in the two side through grooves 102, a first spring 204 is located between the top plate 504 and the slide 201, and a second spring 304 is located between the top plate 504 and the driving slide 301. Slide shafts 505 are provided at both ends of the two top plates 504, and pneumatic telescopic rods 501 are respectively provided on both sides of the bottom support frame 1 and located below the two side through grooves 102. The telescopic ends of the pneumatic telescopic rods 501 are fixedly installed with L-shaped limit plates 502, and the L-shaped limit plates 502 are provided with Y-shaped slide rods 503 that slide in contact with the bottom of the slide shaft 505. Slide sleeves 104 for the L-shaped limit plates 502 to slide up and down are provided on both sides of the bottom support frame body 101.

[0037] Through this structure, the pneumatic telescopic rod 501 is activated and the position of the L-shaped limit plate 502 is adjusted. When the telescopic end of the pneumatic telescopic rod 501 is the shortest, see the attached Figure 4 , the distance between the two adjacent sliding shafts 505 on the same side is the largest, at this time the vibration frequency provided by the first spring 204 and the second spring 304 due to compression is the lowest, when the telescopic end of the pneumatic telescopic rod 501 is the longest, the distance between the two adjacent sliding shafts 505 on the same side is the smallest, at this time the vibration frequency provided by the first spring 204 and the second spring 304 due to compression is the highest.

[0038] Combined with attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 :

[0039] The bottom support frame 1 is provided with a longitudinal vibrator 6 located between the first support frame 2 and the second support frame 3, the slide 201 is provided with a first support rod 202, and the driving slide 301 is provided with a second support rod 302. The longitudinal vibrator 6 includes a rectangular frame 601 located between the first support rod 202, the second support rod 302, the bottom support frame body 101 and the material receiving hopper 9. The rectangular frame 601 is slidably installed on the bottom support frame body 101, and a number of evenly distributed sliding rods 606 are provided at both ends of the rectangular frame 601. A plurality of sliding rods 606 are provided with a limit plate 607 at one end away from the rectangular frame 601, and a third spring 608 is provided between the limit plate 607 and the first support rod 202 and the second support rod 302;

[0040] A limiting sleeve 602 with a limiting through hole is provided on the top of the rectangular frame 601. A limiting slide rod 603 is slidably connected to the limiting sleeve 602. Two limiting slide rods 603 are fixedly connected to a movable plate 605 that can move up and down in the rectangular frame 601. A connecting shaft 610 with both ends exposed from the movable plate 605 is rotatably connected to the movable plate 605. A pendulum 609 is fixedly connected to both ends of the connecting shaft 610.

[0041] A fourth spring 604 is provided between the bottom of the two limiting slide bars 603 and the bottom of the rectangular frame 601 .

[0042] Through the above structure, when the first support rod 202 and the second support rod 302 vibrate with the slide 201 and the driving slide 301, the first support rod 202 and the second support rod 302 are displaced, causing the third spring 608 to be compressed and stretched, thereby causing the rectangular frame 601 to move left and right on the bottom support frame body 101. The rectangular frame body 601 is connected to the bottom support frame body 101 through a limiting slide rail. During the left and right movement of the rectangular frame 601, the pendulum 609 swings, thereby driving the two limiting slides 603 to move up and down through the moving plate 605. The fourth spring 604 is used to increase the frequency of the up and down movement of the limiting slide 603. The two limiting slides 603 are provided with a knocking hammer 611, which causes the knocking hammer 611 to continuously knock on the material receiving hopper 9. See attached Figure 2 The receiving surface of the receiving hopper 9 is an inclined surface, so that the screened material in the receiving hopper 9 can slide out quickly.

[0043] Combined with attachment Figure 1 , Attachment Figure 8 , Attachment Figure 9 and attached Figure 10 :

[0044] One end of the triangular support frame 10 is rotatably connected to the screen 7, and the other end is provided with a shock absorber 8 that can shock the screen material on the screen 7. The triangular support frame 10 includes a double-layer triangular frame 1001 fixedly connected to the first support rod 202. The double-layer triangular frame 1001 is a right triangle. A limiting rotation shaft 1002 is provided at the right angle of the double-layer triangular frame 1001. The screen 7 includes a screen body 701. The bottom of the screen body 701 is provided with a limiting slide 702 that can slide and rotate on the limiting rotation shaft 1002.

[0045] The double-layer triangular frame 1001 is fixedly installed with two symmetrically distributed wedge-shaped chute bodies 1003 at the acute-angle end away from the first support rod 202. The wedge-shaped chute body 1003 is provided with an L-shaped rotating shaft 1004, and the bottom of the wedge-shaped chute body 1003 is provided with an extension plate body 1005. The shock absorber 8 includes a first wedge-shaped slider 801 that can move up and down in the wedge-shaped chute body 1003, and a fifth spring 803 is provided between the first wedge-shaped slider 801 and the extension plate body 1005. A capping wedge-shaped chute body 802 is fixedly installed on the side of the first wedge-shaped slider 801 exposed from the wedge-shaped chute body 1003, and a capping wedge-shaped chute body 802 is slidably connected in the capping wedge-shaped chute body 802. A second wedge-shaped slider 809 is provided with a sixth spring 804 between the second wedge-shaped slider 809 and the capping wedge-shaped chute body 802, a plate body 806 is rotatably connected to the L-shaped rotating shaft 1004, a first limiting protrusion 810 is provided on the second wedge-shaped slider 809, a second limiting protrusion 808 is provided on the side of the plate body 806 close to the second wedge-shaped slider 809, a slope 812 is provided on the top of the plate body 806, and a slope protrusion 805 matching the slope 812 is provided on the top of the capping wedge-shaped chute body 802, a seventh spring 807 is provided between the two plate bodies 806, and a support column 811 is provided between the second wedge-shaped slider 809 and the extension plate body 1005.

[0046] When the screen body 701 is in a state of being vibrated up and down, the screen body 701 is in a state of being vibrated up and down, and the screen body 701 that is in a state of being vibrated up and down is rotated ...

[0047] The second limiting protrusion 808 and the first limiting protrusion 810 contact each other and have a certain friction force. This is the prior art, so it is not described here. When the unscreened particles on the screen body 701 gradually increase, the screen body 701 continues to press down, causing the capping wedge-shaped chute body 802 to slide downward, thereby continuously compressing the fifth spring 803 and the sixth spring 804, so that the fifth spring 803 and the sixth spring 804 continue to accumulate force. When the inclined surface protrusion 805 contacts the inclined surface 812, the inclined surface protrusion 805 continues to increase the downward pressure, which will cause the plate body 806 to need to overcome the pre-tension of the seventh spring 807 and the friction between the second limiting protrusion 808 and the first limiting protrusion 810, so that the plate body 806 has a tendency to rotate. When the plate body 806 starts to rotate to compress the seventh spring 807 and cause the second limiting protrusion 808 to move relative to the first limiting protrusion 810 When the plate 806 rotates to the point where the inclined surface 812 disengages from the inclined surface 805, the second limiting protrusion 808 disengages from the first limiting protrusion 810. At this time, the capping wedge chute body 802 will move downward rapidly under the action of the downward pressure and compress the fifth spring 803 and the sixth spring 804 to the low point. Due to the instantaneous increase in the pressure on the fifth spring 803 and the sixth spring 804, the force is unstable, so that the fifth spring 803 and the sixth spring 804 will rebound up and down after being compressed, and the particles on the screen body 701 will be bounced up and scattered on the screen body 701 again through the capping wedge chute body 802, which has the effect of breaking up the agglomerated particles, thereby improving the screening efficiency.

[0048] During the specific implementation of the present invention, the granular raw materials to be screened are placed on the screen body 701, and the dual-axis drive motor 303 is started. The triangular support frame 10 and the material receiving hopper 9 are vibrated by the vibrating screen power assembly 4, thereby starting the screening operation.

[0049] During the process, the pneumatic telescopic rod 501 is activated to adjust the position of the L-shaped limit plate 502, thereby adjusting the vibration frequency of the triangular support frame 10 and the material receiving hopper 9;

[0050] During the left-right movement of the rectangular frame 601, the pendulum 609 swings, thereby driving the two limit slide bars 603 to move up and down through the movable plate 605. The fourth spring 604 is used to increase the frequency of the up and down movement of the limit slide bar 603. The two limit slide bars 603 are provided with a knocking hammer 611, so that the knocking hammer 611 continuously knocks the material receiving hopper 9, thereby making the material receiving hopper 9 discharge more smoothly.

[0051] When more and more unscreened particles are on the screen body 701, the screen body 701 tilts. At this time, the screen body 701 is filled, which can make the screen body 701 change from the tilted state to a state where one end vibrates up and down. The vibrating screen body 701 at one end will bounce up the particle screening material at the lower end of the screen body 701, thereby solving the problem of screen hole blockage.

[0052] When the amount of unscreened particles on the screen body 701 reaches a certain amount, the bouncing device 8 bounces the unscreened particles on the screen body 701 to break up the agglomerated particles, thereby improving the screening efficiency.

[0053] The above description of the present invention and its embodiments is non-limiting, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above description and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
