Description

Technical Field

[0001] The utility model relates to the technical field of pencil plate carbonization, in particular to a novel pencil plate carbonization device. Background Art

[0002] The pencil plate carbonization device is a crucial equipment in pencil manufacturing. Its main task is to carbonize the pencil plate (graphite plate) by heating, and then produce a pencil lead with a specific hardness and strength. The device generally uses a heating method to carbonize the pencil plate in a high temperature environment. During this process, lignin and volatile substances are decomposed, leaving only carbonaceous substances. By precisely controlling the temperature and time, the hardness and strength of the pencil lead can be flexibly adjusted to meet different needs.

[0003] However, the traditional external heating method with an external burner has many disadvantages. First, the heat needs to be transferred to the furnace through the furnace wall, which leads to uneven heat distribution. The different thickness of the furnace wall leads to different heat transfer speeds, resulting in significant temperature differences in different parts of the furnace, which in turn affects the carbonization uniformity of the pencil board. Some areas may be damaged due to over-carbonization, while other areas are under-carbonized.

[0004] The external heating method is also accompanied by the problem of low thermal efficiency. Part of the heat is dissipated into the environment during the transfer process, which not only wastes energy, but also increases the difficulty of controlling the temperature in the furnace, further exacerbating the problem of uneven heating. Due to the long heat transfer path, the heating speed is relatively slow, which prolongs the carbonization process and reduces production efficiency.

[0005] External heating may also cause uneven pressure distribution in the furnace, which will adversely affect the internal structure of the pencil board and further affect its physical properties. The traditional external heating method with an external burner presents many challenges in the carbonization process of pencil boards, and we need to continuously explore more advanced heating technologies and methods to improve carbonization effects and production efficiency.

Detailed Description of the Preferred Embodiments

[0025] To make the technical means, creative features, achieved purposes and functions of this utility model easy to understand, the following further elaborates this utility model in combination with specific embodiments.

[0026] Such as Figure 1 - Figure 5As shown, an innovative pencil board carbonization device consists of multiple core components. Each component is precisely designed and connected to achieve an efficient pencil board carbonization process. First, let's look at the installation feet 1. As the cornerstone of the entire device, it stably fixes the combustion furnace 2 to the ground. The combustion furnace 2 is the core heat source. Through the combustion chamber inside it, the input combustibles (via the feeding port 3) are fully burned to generate the necessary heat.

[0027] The feeding port 3 and the heat input pipe 4 are respectively ingeniously installed at both ends of the combustion furnace 2. The former is responsible for the input of fuel, and the latter is responsible for transporting heat to the carbonization area. The outer end of the heat input pipe 4 is also ingeniously connected to the heat transfer inner pipe 5 that extends into the filtering inner cylinder 12. This design ensures that heat can directly and efficiently act on the pencil board carbonization process.

[0028] To further optimize the carbonization effect, a support frame 6 is added beside the combustion furnace 2, on which a rotatable heat preservation cylinder 7 is installed. This heat preservation cylinder 7 can not only effectively reduce heat dissipation but also is connected to the driving device 8 through the transmission device 9 to achieve the rotation function, thereby promoting the uniform heating of the pencil board during the carbonization process. Both ends of the heat preservation cylinder 7 are connected to the filtering inner cylinder 12 through the support rings 10, and the space between them forms a debris collection cavity 11 for collecting the debris generated during the carbonization process.

[0029] The barrel wall of the filtering inner cylinder 12 is designed with filter mesh holes 13. This detailed design ensures that the soot and impurities generated during the carbonization process can be effectively filtered, while the clean hot air can smoothly enter the carbonization chamber 14 to heat and carbonize the pencil board. In addition, a bent pipe 15 is provided at the outer end of the heat transfer inner pipe 5, further improving the heat transfer efficiency and stability.

[0030] To enhance the safety and sealing performance of the device, both the feeding port 3 and the discharge door (located at the lower end of the heat preservation cylinder 7) are fixed and sealed using hinge devices, lock devices, and latch devices. At the same time, the outer walls of the heat input pipe 4, the heat transfer inner pipe 5, and the heat preservation cylinder 7 are all wrapped with heat preservation sleeves to reduce heat dissipation and improve energy utilization efficiency.

[0031] A speed reducer is also provided between the transmission device 9 and the driving device 8. This design not only reduces the rotational speed of the driving device 8 but also improves the stability and reliability of the transmission system. All key components are fixed and connected through bolts, nuts, and anti-slip gaskets, ensuring the overall structure of the device is stable and easy to maintain.

[0032] The unique design of the support ring 10 - it consists of a circular ring and multiple annularly distributed bumps. The round holes opened on the bumps allow bolts to be inserted and achieve a firm connection with the heat preservation cylinder 7. The support ring 10 and the inner filtration cylinder 12 are fixed through a threaded connection method, which is simple and reliable, ensuring the stability of the inner filtration cylinder 12 during rotation. This new pencil board carbonization device realizes an efficient and environmentally friendly pencil board carbonization process through its innovative design and precise structure.

[0033] Usage process: Confirm that the installation feet 1 are firmly fixed on the ground to ensure the stability of the combustion furnace 2. Put an appropriate amount of combustibles through the feeding port 3 to prepare for combustion to generate heat. Ignite the combustibles, and the combustion furnace 2 starts to work and generates heat. The heat is conveyed to the carbonization area in the heat preservation cylinder 7 through the heat input pipeline 4 and the heat transfer inner pipe 5. Put the pencil board to be carbonized into the heat preservation cylinder 7. The heat preservation cylinder 7 rotates driven by the transmission device 9 and the driving device 8, making the pencil board evenly heated. The debris and soot generated during the carbonization process are filtered through the filter mesh holes 13 of the inner filtration cylinder 12, and the clean hot air continues to heat and carbonize the pencil board. After carbonization is completed, the carbonized pencil board is discharged through the discharge door at the lower end of the heat preservation cylinder 7. At the same time, the debris in the debris collection cavity 11 can be regularly cleaned to keep the equipment clean and running efficiently.

[0034] Cleaning process: Ensure that the equipment has completely stopped running and disconnect the power supply or close the fuel supply. Clean the residual combustibles and ashes in the combustion furnace 2 through the feeding port 3. Use cleaning tools (such as brushes or vacuum cleaners) to clean the impurities on the inner wall of the combustion furnace 2 and around the feeding port 3. Open the discharge door at the lower end of the heat preservation cylinder 7 to discharge the possible remaining pencil board fragments and impurities during the carbonization process. Use appropriate cleaning tools to clean the inner wall of the heat preservation cylinder 7 and the outer wall of the inner filtration cylinder 12 to ensure there is no dust and debris accumulation. Take out the debris and impurities in the debris collection cavity 11 and handle them properly. Clean the debris collection cavity 11 with clean water or a cleaning agent and dry it to keep it dry. Check whether all connecting parts (such as bolts, nuts, and anti-slip gaskets) are tightened, and tighten them in time if there is any looseness. Check whether the filter mesh holes 13 are blocked, and clean or replace them if necessary. Check the running conditions of the transmission device 9 and the driving device 8 to ensure there is no abnormal noise and vibration. After completing the cleaning and maintenance, ensure that all parts are correctly installed and in good condition. Reconnect the power supply or fuel supply and prepare for the next carbonization operation.
