Description

Technical Field

[0001] The invention relates to the technical field of graphite powder processing, and more specifically, to a graphite powder processing vibration screen. Background Art

[0002] Graphite powder is a powdery substance obtained by crushing and grinding natural graphite or synthetic graphite. It has good electrical conductivity, high temperature resistance, lubricity and chemical stability. It is widely used in industry and is often used as battery materials, lubricants, refractory materials, etc.

[0003] The processing of graphite powder usually includes raw material preparation, crushing, grinding, grading, purification and other processes. Among them, the grading process is to remove coarse particles and impurities in the graphite powder and improve the purity of the graphite powder. The graphite powder vibrating screen is a commonly used equipment in the grading of graphite powder. It uses the principle of vibration to separate impurities and particles that do not meet the requirements in the graphite powder, so as to improve the quality and purity of the graphite powder. At present, the graphite powder processing vibrating screen generally adopts a circular rotary vibrating screen. Under the action of vibration force, the graphite powder is gradually discharged horizontally through the discharge pipe on the outside of the rotary vibrating screen. However, this screening method has certain defects: since the graphite powder is discharged horizontally through the discharge pipe on the outside of the rotary vibrating screen, after the screening operation is completed, some graphite powder that has not been completely discharged may still remain on the screen. This results in the need to run the vibrating screen idling for a period of time after each screening operation to ensure that the graphite powder is completely discharged, which leads to unnecessary energy waste; at the same time, the period of idling of the vibrating screen is also wasted, and the next batch of screening tasks needs to wait until the graphite powder is completely discharged before they can be carried out. Therefore, the continuity of the overall operation is poor, and the overall screening efficiency needs to be improved. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a graphite powder processing vibrating screen, comprising a base and a body fixedly installed on the top of the base by a number of circumferentially distributed vibration springs, a feed port is opened on the top of the body, and a screen and a lower hopper distributed up and down are fixedly installed on the inner wall of the body, the bottom of the screen is fixed and connected with a lower feed pipe 1 that runs through the body, and a lower feed pipe 2 is fixedly installed at the bottom of the lower hopper.

[0005] The actuator assembly includes a rotating shaft 2 rotatably mounted on the inner wall of the top of the machine body and a control panel fixedly mounted on the outside of the rotating shaft 2 and located in the machine body. The top of the control panel is provided with an arc groove corresponding to the feed port and used for feeding. The discharge assembly includes a conical plug slidably mounted on the outside of the rotating shaft 2 through a key groove and matched with a discharge pipe 1. A sliding cylinder slidably connected to the rotating shaft 2 is fixedly mounted on the top of the conical plug.

[0006] Furthermore, the intermittent component includes a groove wheel fixedly mounted on the top of the second rotating shaft and a driving wheel rotatably installed on the top of the machine body, two driving rods are fixedly installed on the bottom of the driving wheel, and levers matching the groove wheel are fixedly installed on the top of the two driving rods.

[0007] Furthermore, the intermittent feeding unit also includes a mounting seat fixedly installed on the right side of the base and a limiting sleeve fixedly installed on the outside of the machine body. A rotating shaft three that slides with the limiting sleeve is rotatably installed on the top of the mounting seat, and the top of the rotating shaft three is connected to the rotating shaft of the driving wheel by belt drive.

[0008] Furthermore, the shaking assembly includes a mounting plate fixedly mounted on the inner wall of the body and a return spring fixedly mounted on the top of the mounting plate, a collision plate movably abutting against the screen is fixedly mounted on the top of the return spring, and a limiting rod sliding through the mounting plate is fixedly mounted on the bottom of the collision plate.

[0009] Furthermore, the driving assembly includes a fixed pulley and a mounting sleeve fixedly mounted on the bottom of the mounting plate, a sliding rod is slidably mounted on the lower end of the mounting sleeve, a sliding plate is fixedly mounted on the side of the sliding rod away from the second rotating axis, and an arc plate is fixedly mounted on the side of the sliding plate close to the second rotating axis.

[0010] Furthermore, a pull rope is wound around the outside of the fixed pulley, and both ends of the pull rope are fixedly connected to the corresponding collision plate and the sliding rod respectively. The reset spring is sleeved on the outside of the pull rope, and the pull rope is slidably connected to the corresponding mounting plate. The shake prevention unit also includes an extrusion rod fixedly installed at the second bottom end of the rotating shaft and matched with the arc plate.

[0011] Furthermore, the lifting assembly includes an arc-shaped lifting plate fixedly mounted on the inner wall of the machine body, a tension rod matched with the lifting plate is fixedly mounted on the outer side of the sliding cylinder, and an inclined surface matched with the tension rod is provided on the lifting plate.

[0012] Furthermore, the vibration unit includes two pairs of fixed plates fixedly installed at the bottom of the body and symmetrically on the left and right, a rotating shaft 1 is rotatably installed between the same pair of fixed plates, two eccentric wheels symmetrically arranged on the outer side of the rotating shaft 1, a driving motor fixedly connected to the right rotating shaft 1 is fixedly installed on the rear side of the right rear fixed plate, and the left and right rotating shafts 1 are connected by belt drive.

[0014] The beneficial effects of the present invention are: 1. The intermittent feeding effect is achieved by intermittently connecting the arc groove on the control panel with the feed port. When the graphite powder on the screen accumulates to a certain extent, the feed port will be blocked by the control panel to stop feeding, leaving time and space for the screen to be screened. After the graphite powder on the screen is screened, the feed port is opened again to continue feeding. The intermittent feeding mechanism effectively avoids the problems of screening difficulties, screen overload and blockage caused by excessive screening of graphite powder at one time, thereby effectively improving the screening efficiency and screening effect.

[0015] 2. The return spring drives the collision plate to rebound and collide with the screen, impacting the screen and causing it to vibrate. This not only significantly avoids the blockage of the screen, but also utilizes the rotation action of the rotating shaft 2 to drive the control plate to control the intermittent feeding, thereby achieving the effect of intermittent cleaning of the screen and promoting the continuity and efficiency of the screening process.

[0016] 3. Through the cooperation of the vibration unit, intermittent feeding unit, shaking anti-blocking unit and automatic discharging unit, the feeding, stopping feeding, shaking anti-blocking, pulling out and re-feeding in the whole screening process are closely connected and coordinated with each other, forming an efficient and automated screening process.

[0017] 4. The lifting plate cooperates with the tension rod to achieve the effect of intermittent discharge of large-particle graphite powder on the top of the screen, so that after the screening operation is completed, there is no need to run the equipment idling to discharge the material, and the next batch of graphite powder can be directly screened, which greatly improves the screening efficiency during the continuous screening operation.

DETAILED DESCRIPTION

[0027] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0028] See also Figure 1 and Figure 2In this embodiment, a graphite powder processing vibration screen is proposed, including a base 1 and a body 3 fixedly installed on the top of the base 1 through a plurality of vibration springs 2 distributed circumferentially, a feed port is opened on the top of the body 3, and a screen 8 and a lower hopper 9 distributed up and down are fixedly installed on the inner wall of the body 3, the bottom of the screen 8 is fixed and connected with a lower feed pipe 10 that runs through the body 3, and a lower feed pipe 2 11 is fixedly installed at the bottom of the lower hopper 9. A vibration unit 4, an intermittent feeding unit 5, a shaking anti-blocking unit 6 and an automatic discharging unit 7 are arranged on the body 3, the intermittent feeding unit 5 includes an actuator component 501 and an intermittent component 502 for controlling the intermittent movement of the actuator component 501, the shaking anti-blocking unit 6 includes two front-to-back symmetrical shaking components 601 and two driving components 602 for driving the shaking component 601 to beat the screen 8, the automatic discharging unit 7 includes a discharging component 701 and a lifting component 702 for lifting the discharging component 701, and the screen 8 is in the shape of a funnel with a downward depression in the middle.

[0029] See also Figure 1 , Figure 2 and Figure 3 The vibration unit 4 includes two pairs of fixed plates 401 fixedly installed at the bottom of the body 3 and symmetrically on the left and right. A rotating shaft 402 is rotatably installed between the same pair of fixed plates 401. Two eccentric wheels 403 symmetrically arranged on the outer side of the rotating shaft 402 are fixedly sleeved. A driving motor 404 fixedly connected to the right rotating shaft 402 is fixedly installed on the rear side of the right rear fixed plate 401. The left and right rotating shafts 402 are connected by belt transmission.

[0030] When in use, the execution component 501 initially controls the feed port to be opened, and the graphite powder to be screened is introduced into the machine body 3 through the feed port and falls on the top of the screen 8. Then, the drive motor 404 is started, and the output shaft of the drive motor 404 rotates to drive the right rotating shaft 402 to rotate. The right rotating shaft 402 rotates to drive the left rotating shaft 402 to rotate through a belt transmission, so that the two rotating shafts 402 rotate synchronously, and then drive the eccentric wheels 403 on the left and right sides to rotate. The eccentric wheel 403 makes the machine body 3 vibrate up and down. During this process, the vibration spring 2 is reciprocatingly compressed and extended, and the screen 8 vibrates up and down synchronously with the machine body 3. The vibration is used to screen the graphite powder on the top of the screen 8. The smaller particles of graphite powder pass through the screen 8 and fall on the top of the lower hopper 9 and are discharged through the lower feed pipe 11. The larger particles of graphite powder that have not been screened stay on the top of the screen 8 and are discharged through the lower feed pipe 10 as the lifting component 702 controls the discharging component 701 to be intermittently lifted, thereby realizing the screening of the graphite powder.

[0031] See also Figure 2 , Figure 4 , Figure 6 and Figure 8The actuator component 501 includes a rotating shaft 5011 rotatably mounted on the inner wall of the top of the body 3 and a control board 5012 fixedly mounted on the outside of the rotating shaft 5011 and located in the body 3. The intermittent component 502 includes a groove wheel 5021 fixedly sleeved on the top of the rotating shaft 5011 and a driving wheel 5022 rotatably mounted on the top of the body 3. Two driving rods 5023 are fixedly mounted on the bottom of the driving wheel 5022. The tops of the two driving rods 5023 are fixedly mounted with levers 5024 that match the groove wheel 5021. The top of the control board 5012 is provided with an arc groove corresponding to the feed port and used for feeding.

[0032] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 The intermittent feeding unit 5 also includes a mounting seat 503 fixedly mounted on the right side of the base 1 and a limiting sleeve 504 fixedly mounted on the outside of the body 3. A rotating shaft 3 5025 that slides with the limiting sleeve 504 is rotatably mounted on the top of the mounting seat 503. The top of the rotating shaft 3 5025 is connected to the rotating shaft of the driving wheel 5022 by belt drive.

[0033] See also Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 The intermittent component 502 also includes a worm 5026 fixedly mounted on the outside of the right rotating shaft 1 402 and a worm wheel 5027 fixedly sleeved on the outside of the rotating shaft 3 5025 and meshing with the worm 5026 .

[0034] When in use, during the feeding process, the output shaft of the driving motor 404 rotates to drive the right rotating shaft 1 402 to rotate, and the worm 5026 is also synchronously driven to rotate. The worm 5026 is meshed with the worm wheel 5027, so the rotation of the worm 5026 drives the rotating shaft 3 5025 to rotate through the worm wheel 5027, and the transmission system composed of the worm 5026 and the worm wheel 5027 has a deceleration function, and then the rotating shaft 3 5025 rotates at a uniform speed and drives the driving wheel 5022 to rotate through the belt transmission. The driving wheel 5022 rotates through the driving rod 5023 to drive the lever 5024 to gradually drive the groove wheel 5021 to rotate, thereby driving the rotating shaft 5011 to rotate, and then driving the control board 5012 to rotate, so that the arc groove on the control board 5012 is staggered with the feed port, so that the feed port is completely blocked, thereby stopping the feeding, and as the control board 5012 continues to rotate, when the arc groove on the control board 5012 gradually rotates to dock with the feed port, the feed port is reopened and feeding is started again, thereby achieving the effect of intermittent feeding. When the graphite powder on the screen 8 accumulates to a certain extent, the feed port will be blocked by the control panel 5012 and the feeding will be stopped, leaving time and space for the screen 8 to be fully and effectively screened. After the graphite powder on the screen 8 is basically screened, the feed port is opened again and the feeding continues. The intermittent feeding mechanism effectively avoids excessive screening of graphite powder at one time, resulting in reduced screening efficiency and overloading and clogging of the screen 8, thereby effectively improving the screening efficiency and screening effect.

[0035] See also Figure 2 , Figure 4 , Figure 5 and Figure 7 The shaking component 601 includes a mounting plate 6011 fixedly mounted on the inner wall of the body 3 and a return spring 6012 fixedly mounted on the top of the mounting plate 6011, a collision plate 6013 that movably contacts the screen 8 is fixedly mounted on the top of the return spring 6012, and a limiting rod 6014 that slides through the mounting plate 6011 is fixedly mounted on the bottom of the collision plate 6013.

[0036] See also Figure 2 , Figure 4 , Figure 5 and Figure 7 The driving assembly 602 includes a fixed pulley 6021 and a mounting sleeve 6022 fixedly mounted on the bottom of the mounting plate 6011, a sliding rod 6023 is slidably mounted on the lower end of the mounting sleeve 6022, a sliding plate 6024 is fixedly mounted on the side of the sliding rod 6023 away from the second rotating shaft 5011, and an arc plate 6025 is fixedly mounted on the side of the sliding plate 6024 close to the second rotating shaft 5011.

[0037] See also Figure 2 , Figure 4 , Figure 5 and Figure 7A pull rope 6026 is wound around the outside of the fixed pulley 6021, and the two ends of the pull rope 6026 are respectively fixedly connected to the corresponding collision plate 6013 and the sliding rod 6023. The reset spring 6012 is sleeved on the outside of the pull rope 6026, and the pull rope 6026 is slidingly connected to the corresponding mounting plate 6011. The anti-shake unit 6 also includes an extrusion rod 603 fixedly installed at the bottom end of the rotating shaft 5011 and matched with the arc plate 6025.

[0038] When in use, the second rotating shaft 5011 rotates to drive the control plate 5012 to rotate, and also drives the extrusion rod 603 to rotate synchronously (the rotation direction is as follows: Figure 5 As shown in the middle shear head, when the arc groove on the control plate 5012 is offset from the feed port and the feed is stopped, the extrusion rod 603 rotates to contact the arc plate 6025 and as the second rotating shaft 5011 continues to rotate, the extrusion rod 603 will squeeze the arc plate 6025 and push the arc plate 6025 to move away from the second rotating shaft 5011, so that the sliding plate 6024 drives the sliding rod 6023 to move synchronously and pull the pull rope 6026, and then the collision plate 6013 is pulled by the pull rope 6026. The collision plate 6013 moves downward under the limit of the limit rod 6014 and compresses the reset spring 6012. When the extrusion rod 60 When the return spring 6012 is out of contact with the arc plate 6025, the pressure on the return spring 6012 is released, and the accumulated elastic potential energy is released to push the collision plate 6013 to rebound and collide with the screen 8, thereby impacting the screen 8 and the graphite powder blocked in the mesh of the screen 8. The graphite powder is shaken out by the upward impact force from the collision plate 6013, thereby breaking away from the mesh, which not only effectively avoids the blockage of the screen 8, but also utilizes the rotation action of the rotating shaft 5011 to drive the control plate 5012 to control the intermittent feeding, thereby achieving the effect of intermittent cleaning of the screen 8, thereby achieving the continuity and high efficiency of the screening process.

[0039] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The discharge assembly 701 includes a conical plug 7011 which is slidably installed on the outside of the rotating shaft 5011 through a keyway and cooperates with the discharge pipe 10. A sliding cylinder 7012 which is slidably connected to the rotating shaft 5011 is fixedly installed on the top of the conical plug 7011. Initially, the conical plug 7011 blocks the connection between the discharge pipe 10 and the screen 8 under the action of gravity.

[0040] See also Figure 2 , Figure 4 , Figure 5 and Figure 6The lifting assembly 702 includes an arc-shaped lifting plate 7022 fixedly mounted on the inner wall of the machine body 3, a tension rod 7021 matched with the lifting plate 7022 is fixedly mounted on the outer side of the sliding cylinder 7012, and an inclined surface matched with the tension rod 7021 is provided on the lifting plate 7022.

[0041] During specific use, the rotating shaft 5011 will also drive the conical plug 7011 to rotate synchronously during the rotation process. When the extrusion rod 603 is out of contact with the arc plate 6025, the rotating shaft 5011 continues to drive the conical plug 7011 to rotate and drives the tension rod 7021 to rotate through the sliding cylinder 7012. When the tension rod 7021 contacts the inclined surface of the lifting plate 7022 and continues to rotate, the inclined surface of the lifting plate 7022 squeezes the tension rod 7021 to move the tension rod 7021 upward, thereby driving the conical plug 7011 to move upward through the sliding cylinder 7012. When the tension rod 7021 moves to the top of the lifting plate 7022, the tension rod 7021 continues to rotate but does not continue to move upward, but slides along the top of the lifting plate 7022. This process During the process, the conical plug 7011 is separated from the discharge pipe 10, and the discharge pipe 10 is opened. At this time, the larger particles of graphite powder on the top of the screen 8 enter the discharge pipe 10 along the inclined surface of the screen 8 and are discharged through the discharge pipe 10. When the tension rod 7021 rotates to separate from the lifting plate 7022, the conical plug 7011 drives the tension rod 7021 to move downward and reset through the sliding cylinder 7012 under the action of gravity. At this time, the conical plug 7011 plugs the discharge pipe 10 again, and then as the control board 5012 continues to rotate, the arc groove on the control board 5012 is re-aligned with the feed port and feeding starts again. The feeding, stopping of feeding, shaking to prevent blocking, pulling out and feeding again in the entire screening process are closely connected and coordinated with each other, forming an efficient and automated screening process.

[0042] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
