Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon processing technology, specifically to a high-purity carbon powder pyrolysis furnace discharge drum screen. Background Technology
[0002] Pyrolysis is an important method for producing high-purity carbon powder, capable of converting it into high-value-added materials such as carbon nanotubes, graphene precursors, and carbon conductive fillers. After pyrolysis, the solid materials discharged from the pyrolysis furnace need to be screened through a drum screen before entering subsequent processing steps. Because the composition of the pyrolysis products discharged from the furnace is relatively complex, the discharge drum screen is prone to clogging during use. Therefore, frequent cleaning of the drum screen is necessary to prevent clogging. However, existing cleaning devices are either too complex and costly, or their cleaning effect is insufficient, failing to effectively solve the clogging problem. Summary of the Invention
[0003] The purpose of this invention is to provide a high-purity carbon powder pyrolysis furnace discharge drum screen that can achieve automatic cleaning.
[0004] To achieve the above-mentioned invention objectives, the technical solution adopted by this utility model is: a high-purity carbon powder pyrolysis furnace discharge drum screen, including a screen body set on a frame, and a cleaning brush extending along the length of the screen body is arranged side by side on the upper part of one side of the screen body. The cleaning brush includes a brush shaft and brush bristles set on the brush shaft. The cleaning brush contacts the screen body through the brush bristles.
[0005] Above the screen body, a rotating shaft extending along the length of the screen body is also provided. A first synchronous pulley is provided at one end of the rotating shaft, and a second synchronous pulley is provided on the screen shaft at one end of the screen body. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt. Several sets of beating components are provided on the rotating shaft along the length of the rotating shaft. The beating components include a first rubber beating plate and a sleeve fixedly sleeved outside the rotating shaft. One end of the first rubber beating plate is fixedly connected to the sleeve.
[0006] Preferably, the patting assembly further includes a second rubber patting piece, one end of which is fixedly connected to the middle section of the first rubber patting piece, and the other end extends beyond the first rubber patting piece; a U-shaped elastic support clip is provided between the first rubber patting piece and the second rubber patting piece.
[0007] Preferably, the side of the first and second rubber beating plates facing the screen body is also provided with nylon needles when the first and second rubber beating plates rotate with the rotating shaft.
[0008] Preferably, the first rubber striking plate and the second rubber striking plate are riveted together by rivets.
[0009] The beneficial effects of this utility model are mainly reflected in: it can effectively clean the screen holes of the screen body, prevent screen hole blockage, and requires no additional power drive, with a simple structure and low cost. Specifically, during use, the material enters from one end of the screen body and is screened as the screen body rotates; as the screen body rotates, the cleaning brush in contact with it rotates under the action of friction, thus cleaning the blockage in the screen holes; furthermore, as the screen body rotates, its rotational torque is transmitted to the rotating shaft in sequence through the screen shaft, the second synchronous pulley, the synchronous belt, and the first synchronous pulley. As the rotating shaft rotates continuously, it can drive the sleeve of the beating component to rotate, thereby causing the first rubber beating plate to repeatedly beat and impact the screen body, thus preventing the screen holes of the screen body from becoming blocked. When the preferred slapping assembly with a second rubber slapping plate is in operation, its first and second rubber slapping plates can perform two slaps within one slapping cycle, achieving the dual effects of loosening and knocking down. Its elastic support clip, due to its elasticity, ensures the slapping force at the end of the second rubber slapping plate while avoiding excessive rigidity, resulting in excellent performance.

[0011] Figure 2 This is a schematic diagram of the rotating shaft.
[0012] Figure 3 This is a schematic diagram of a preferred tapping component. Detailed Implementation
[0013] like Figure 1-3 As shown, this utility model is a high-purity carbon powder pyrolysis furnace discharge drum screen, used for preliminary screening of materials discharged from the pyrolysis furnace, such as... Figure 1 The diagram shown is a structural schematic of the end of this utility model, which includes a screen body 1 mounted on a frame. A cleaning brush 2 extending along the length of the screen body 1 is arranged side by side on the upper part of one side of the screen body 1. The cleaning brush 2 includes a brush shaft and bristles mounted on the brush shaft. The cleaning brush 2 contacts the screen body 1 through the bristles. During use, the material enters from one end of the screen body 1 and is screened as the screen body 1 rotates. As the screen body 1 rotates, the cleaning brush 2 in contact with it rotates under the action of friction, thus cleaning the blockages in the screen holes. The cleaning brush 2 has no other power intervention and can move freely under the action of friction to achieve hole cleaning.
[0014] The present invention further includes a rotating shaft 3 extending along the length of the screen body 1 above the screen body 1. A first synchronous pulley 4 is mounted at one end of the rotating shaft 3, and a second synchronous pulley 5 is mounted on the screen shaft at one end of the screen body 1. The first synchronous pulley 4 and the second synchronous pulley 5 are connected by a synchronous belt 6, meaning that the power source of the rotating shaft 3 is the rotational power of the screen body 1, which is connected to the power of the screen body 1 through the first synchronous pulley 4, the second synchronous pulley 5, and the synchronous belt 6. The rotating shaft 3 can be installed using the end plate of the drum screen frame (supported by a support rod) or by suspension.
[0015] like Figure 2 As shown, the present invention provides several sets of beating components along the length of the rotating shaft 3. Each beating component includes a first rubber beating plate 7 and a sleeve 8 fixedly fitted outside the rotating shaft 3. One end of the first rubber beating plate 7 is fixedly connected to the sleeve 8. As the sieve body 1 rotates, its rotational torque is transmitted to the rotating shaft 3 sequentially through the sieve shaft, the second synchronous pulley 5, the synchronous belt 6, and the first synchronous pulley 4. As the rotating shaft 3 rotates continuously, it drives the sleeve 8 of the beating component to rotate, thereby causing the first rubber beating plate to repeatedly beat and impact the sieve body 1, thus preventing the sieve holes from becoming clogged.
[0016] To further enhance the patting effect, such as Figure 3 As shown, the beating assembly of this utility model also includes a second rubber beating plate 9. One end of the second rubber beating plate 9 is fixedly connected to the middle section of the first rubber beating plate 7, and the first rubber beating plate 7 and the second rubber beating plate 9 are riveted together. The other end of the second rubber beating plate 9 extends beyond the first rubber beating plate 7, with half of the extension length being approximately half of its own length. A U-shaped elastic support clip 10 is provided between the first rubber beating plate 7 and the second rubber beating plate 9. During operation, the first rubber beating plate 7 and the second rubber beating plate 9 can achieve two beatings within one beating cycle, achieving the dual effects of loosening and knocking down. The elastic support clip 10 is elastic, ensuring the beating force at the end of the second rubber beating plate 9 while avoiding excessive rigid impact, preventing damage to the screen body 1, resulting in excellent performance.
[0017] Based on this, a better approach is that the first rubber striking plate 7 and the second rubber striking plate 9 are provided with needles on the side facing the sieve body 1 when they rotate with the rotating shaft 3. After striking, the needles can penetrate into the sieve holes to form cleaning holes. The needles are generally nylon needles 11, which have good softness and puncture resistance.
