Description

Technical Field

[0001] This utility model belongs to the field of graphite processing technology, and specifically relates to a continuous screening device for graphite processing. Background Technology

[0002] As a key basic material, graphite plays a crucial role in numerous fields. From its use as a carbon raiser and lubricant in the traditional steel metallurgy industry, to its application in emerging new energy fields as anode materials for lithium-ion batteries, and in the manufacture of high-precision graphite electrodes in the electronics industry, the market demand for graphite continues to experience explosive growth.

[0003] Traditional screening devices mostly use simple static screens or rudimentary vibrating screens, which are inadequate for handling the demands of large-scale, high-precision graphite processing. On the one hand, static screens have extremely low screening efficiency, relying solely on the material's own gravity to slowly pass through the screen, thus limiting production capacity. On the other hand, while simple vibrating screens can improve screening speed to some extent, the difficulty in precisely controlling the vibration frequency and amplitude can easily lead to problems such as screen clogging and material jumping out. Utility Model Content

[0004] The purpose of this invention is to provide a continuous screening device for graphite processing, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A continuous screening device for graphite processing includes,

[0007] The feeding assembly includes a bracket, a support plate fixedly connected to the top of the bracket, a hopper installed in the middle of the support plate, a connecting rod rotatably installed on the side wall of the support plate, and a material box rotatably installed at the lower end of the connecting rod.

[0008] The screening assembly includes a main shaft rotatably mounted on the side wall of the hopper, a turntable fixedly mounted on the middle position of the main shaft, a scraper adapted to be mounted on the side wall of the turntable, a secondary shaft rotatably mounted on the side wall of the support, an eccentric wheel rotatably connected to the end of the secondary shaft, and a lever adapted to be mounted on the side wall of the eccentric wheel, the end of the lever being rotatably connected to the side wall of the hopper.

[0009] As a preferred embodiment of the present invention, the screening assembly further includes a first pulley adapted to be installed at the ends of the main shaft and the secondary shaft, and a first belt adapted to be installed on the side wall of the first pulley, and the two sets of first pulleys are connected by the first belt drive.

[0010] As a preferred embodiment of the present invention, the screening assembly further includes a second pulley installed at the end of the main shaft, a motor fixedly installed on the side wall of the support plate, a main pulley adapted to be installed at the output end of the motor, and a second belt adapted to be installed on the side wall of the main pulley and the second pulley, wherein the main pulley and the side wall of the second pulley are connected by the second belt drive.

[0011] As a preferred embodiment of this utility model, the feeding assembly further includes a screen plate installed in the middle of the material box. The screen plate is installed below the bottom discharge port of the hopper. The material box runs in the middle of the support, and the material box does not contact the bottom of the support plate.

[0012] In a preferred embodiment of this utility model, the feeding assembly is inserted into the insert plate on the side wall of the hopper, and the insert plate is tightly fitted to the inside of the hopper.

[0013] As a preferred embodiment of the present invention, the feeding assembly further includes a positioning post fixedly connected to the side wall of the support plate, the upper end of the positioning post being inserted into the inner side of the middle sliding groove of the insert plate.

[0014] As a preferred embodiment of the present invention, the feeding assembly further includes a baffle installed at the end of the material box, and the baffle is installed on the outside of the bracket.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the linkage design between the connecting rod and the material box of the feeding component, and the dual-shaft drive of the screening component combined with the synergistic effect of the scraper and the lever, realize continuous and automated operation of graphite feeding and screening, shorten the processing cycle, and can process more graphite raw materials per unit time compared with traditional intermittent screening equipment, providing a strong guarantee for large-scale production of graphite products and effectively improving the overall production capacity. In terms of screening accuracy, the centrifugal dispersion of the scraper and the auxiliary shaking of the lever make the distribution of graphite raw materials on the screen more uniform, fully exposed to the screen pores, avoiding the situation of missed screening and misscreening due to local screen blockage caused by raw material accumulation. The bracket integrates the two major components of feeding and screening, and the layout of each component is reasonable and the connection is tight, reducing the equipment footprint and facilitating its placement in the factory workshop.

[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a continuous screening device for graphite processing, comprising:

[0027] The feeding assembly 100 includes a bracket 101, a support plate 102 fixedly connected to the top of the bracket 101, a hopper 103 installed in the middle of the support plate 102, a connecting rod 104 rotatably installed on the side wall of the support plate 102, and a material box 105 rotatably installed at the lower end of the connecting rod 104.

[0028] The screening assembly 200 includes a main shaft 201 rotatably mounted on the side wall of the hopper 103, a turntable 202 fixedly mounted in the middle of the main shaft 201, a scraper 203 adapted to be mounted on the side wall of the turntable 202, a secondary shaft 204 rotatably mounted on the side wall of the support 101, an eccentric wheel 205 rotatably connected to the end of the secondary shaft 204, and a lever 206 adapted to be mounted on the side wall of the eccentric wheel 205, the end of the lever 206 being rotatably connected to the side wall of the hopper 105.

[0029] In the feeding stage, the feeding assembly 100 initiates the material conveying process, providing stable support for the upper components. The support plate 102, fixedly connected to the top of the bracket 101, supports the crucial hopper 103. After the graphite raw material is poured into the hopper 103, the screening assembly 200 immediately follows the feeding process, initiating fine screening operations. The main shaft 201, rotating and mounted on the side wall of the hopper 103, is also driven by an external power source (e.g., directly connected to a motor or driven by adjusting the speed through a reducer). This drives the turntable 202, fixedly mounted in the middle position, to rotate at high speed. The scraper 203, adapted to be mounted on the side wall of the turntable 202, rotates along with the turntable 202. When the graphite raw material falls and contacts the scraper 203, the scraper 203, using the centrifugal force generated by its high-speed rotation, throws the graphite raw material outwards, dispersing it evenly on the screen of the material box 105. Simultaneously, the secondary shaft 204, rotating and mounted on the side wall of the bracket 101, rotates under the power source, causing the eccentric wheel 205 at its end to move eccentrically. The end of the lever 206 on the side wall of the eccentric wheel 205 is rotatably connected to the side wall of the hopper 105. The rotation of the eccentric wheel 205 causes the lever 206 to push the hopper 105 to produce a slight additional sway. This sway further assists the graphite raw material to move on the screen of the hopper 105, ensuring that graphite particles of different sizes can fully contact the screen, improving the accuracy and efficiency of screening. Finally, the graphite particles that meet the specifications fall through the screen and are collected, while the large particles that do not pass through remain on the screen for subsequent processing. The swaying of the hopper 105 allows the graphite raw material to fall evenly and continuously from the hopper 103 into the screening area below, avoiding raw material accumulation and blockage, and ensuring a smooth and stable feeding process.

[0030] Specifically, the screening assembly 200 also includes a first pulley 207 adapted to be installed at the ends of the main shaft 201 and the secondary shaft 204, and a first belt 208 adapted to be installed on the side wall of the first pulley 207. The two sets of first pulleys 207 are connected by the first belt 208.

[0031] In this design, a first pulley 207 is added to the end of the main shaft 201 to cooperate with the secondary shaft 204. With the cooperation of the first belt 208 and the first pulley 207, the main shaft 201 can drive the secondary shaft 204 to rotate synchronously, thereby driving the material box 105 to swing synchronously when discharging material, so that the material continuously shakes in the middle of the material box 105, further settles, and improves the material screening efficiency.

[0032] Furthermore, the screening assembly 200 also includes a second pulley 209 installed at the end of the main shaft 201, a motor 210 fixedly installed on the side wall of the support plate 102, a main pulley 211 adapted to be installed at the output end of the motor 210, and a second belt 212 adapted to be installed on the side wall of the main pulley 211 and the second pulley 209. The main pulley 211 and the side wall of the second pulley 209 are connected by the second belt 212.

[0033] When the equipment is started, the motor 210 drives the main pulley 211 to rotate at high speed. The rotational power of the main pulley 211 and the second pulley 209 installed at the end of the main shaft 201 will drive the second pulley 209 to rotate through the second belt 212, thereby driving the main shaft 201 to rotate, so that the turntable 202 runs in the middle of the hopper 103.

[0034] Furthermore, the feeding assembly 100 also includes a screen plate 106 installed in the middle of the material box 105. The screen plate 106 is installed below the bottom discharge port of the hopper 103. The material box 105 runs in the middle of the support 101, and the material box 105 does not contact the bottom of the support plate 102.

[0035] A screen plate 106 is added in the middle of the material box 105 to assist in screening materials, improve material screening efficiency, prevent large particles from entering the middle of the material box 105, and at the same time, it can make the clumped materials break up with the swing of the material box 105 with the cooperation of the screen plate 106.

[0036] Preferably, the feeding assembly 100 is inserted into the insert plate 107 on the side wall of the hopper 103, and the insert plate 107 fits tightly against the inside of the hopper 103.

[0037] Among them, the addition of a slide plate 107 to connect with the hopper 103 makes it convenient to open or close the hopper 103 according to the production progress, reducing the impact of the external environment on the hopper 103.

[0038] It should be noted that the feeding assembly 100 also includes a positioning post 108 fixedly connected to the side wall of the support plate 102, with the upper end of the positioning post 108 inserted into the inner side of the middle slide groove of the insert plate 107.

[0039] Among them, a positioning post 108 is added. The positioning post 108 is used to limit the insertion plate 107 and prevent the insertion plate 107 from falling off the side wall of the hopper 103.

[0040] Preferably, the feeding assembly 100 further includes a baffle 109 installed at the end of the material box 105, and the baffle 109 is installed on the outside of the bracket 101.

[0041] Among them, a baffle 109 is added. The baffle 109 is used to close the end of the material box 105. Opening the baffle 109 facilitates the material box 105 to perform material feeding operations.

[0042] During use, in the feeding stage, the feeding assembly 100 initiates the material conveying process, providing stable support for the upper components. The support plate 102, fixedly connected to the top of the bracket 101, supports the crucial hopper 103. After the graphite raw material is poured into the hopper 103, the screening assembly 200 immediately follows the feeding process, initiating fine screening operations. The main shaft 201, rotating and mounted on the side wall of the hopper 103, is also driven by an external power source (e.g., directly connected to a motor or driven by adjusting the speed through a reducer), driving the turntable 202, fixedly mounted in the middle, to rotate at high speed. The scraper 203, adapted to be mounted on the side wall of the turntable 202, rotates along with the turntable 202. When the graphite raw material falls and contacts the scraper 203, the scraper 203, using the centrifugal force generated by its high-speed rotation, throws the graphite raw material outwards, dispersing it evenly on the screen of the material box 105. Simultaneously, the secondary shaft 204, rotating and mounted on the side wall of the bracket 101, rotates under the power source, causing the eccentric wheel 205 at its end to move eccentrically, adapting to be mounted on the secondary shaft 204. The end of the lever 206 on the side wall of the eccentric wheel 205 is rotatably connected to the side wall of the hopper 105. The rotation of the eccentric wheel 205 causes the lever 206 to push the hopper 105 to produce a slight additional sway. This sway further assists the graphite raw material to move on the screen of the hopper 105, ensuring that graphite particles of different sizes can fully contact the screen, improving the accuracy and efficiency of screening. Finally, the graphite particles that meet the specifications fall through the screen and are collected, while the large particles that do not pass through remain on the screen for subsequent processing. The swaying of the hopper 105 allows the graphite raw material to fall evenly and continuously from the hopper 103 into the screening area below, avoiding raw material accumulation and blockage, and ensuring a smooth and stable feeding process.

[0043] In summary, the linkage design between the feeding assembly and the hopper, along with the dual-shaft drive (main shaft and auxiliary shaft) of the screening assembly and the synergistic effect of the scraper and lever, achieves continuous and automated operation of graphite feeding and screening, shortening the processing cycle. Compared to traditional intermittent screening equipment, it can process more graphite raw materials per unit time, providing a strong guarantee for large-scale production of graphite products and effectively improving overall capacity. In terms of screening accuracy, the centrifugal dispersion of the scraper and the auxiliary shaking of the lever ensure a more uniform distribution of graphite raw materials on the screen, fully exposing the screen pores and avoiding missed or incorrect screening due to localized screen blockage caused by raw material accumulation. The support integrates the feeding and screening components, with a reasonable layout and tight connection of each component, reducing the equipment's footprint and facilitating its placement in the factory workshop.
