Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicon carbide rod impurity collection technology, and in particular to a silicon carbide rod impurity collector. Background Technology
[0002] Silicon carbide heating rods are rod-shaped or tubular non-metallic high-temperature electric heating elements made from high-purity green hexagonal silicon carbide as the main raw material, processed into blanks according to a certain material ratio, and then sintered at a high temperature of 2200℃ through siliconization and recrystallization. They can operate normally at temperatures up to 1450℃ in oxidizing atmospheres and can be used continuously for up to 2000 hours. When paired with an automated electrical control system, precise and constant temperatures can be achieved, and the temperature can be automatically adjusted according to the needs of the production process. Heating with silicon carbide heating rods is both convenient and safe and reliable. They are now widely used in high-temperature fields such as electronics, magnetic materials, powder metallurgy, ceramics, glass, semiconductors, analytical testing, and scientific research, serving as electric heating elements for tunnel kilns, roller kilns, glass furnaces, vacuum furnaces, muffle furnaces, smelting furnaces, and various other heating equipment.
[0003] When existing devices are in use, the existing separation technology mostly relies on complex filter membranes or adsorbents, which not only increases the manufacturing cost of the device, but also has problems such as easy clogging and aging of filter materials, requiring frequent replacement of consumables, which greatly increases the operation and maintenance costs and equipment downtime. Therefore, we propose a silicon carbide rod impurity collector to solve the above problems. Utility Model Content
[0004] The main objective of this invention is to provide a silicon carbide rod impurity collector that can effectively solve the problems mentioned above.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A silicon carbide rod impurity collector includes a support assembly, a separation assembly mounted on the upper part of the support assembly, a driving assembly mounted on the upper part of the support assembly, a scraping assembly mounted on the upper part of the support assembly, a collection assembly mounted on the rear part of the support assembly, and a plurality of silicon carbide rod bodies mounted in the inner cavity of the support assembly.
[0007] Preferably, the support assembly includes a silicon carbide rod furnace shell, with support legs fixedly connected to the four lower corners of the silicon carbide rod furnace shell, and a rotating door installed inside the silicon carbide rod furnace shell, with a handle installed on the left end of the rotating door.
[0008] Preferably, the separation component includes a support frame 1, two support frames 1 are installed on the upper end of the silicon carbide rod electric furnace shell, and a closed shell is installed on the end of the two support frames 1 that are close to each other. A curved block 1 is installed on the upper end of the closed shell, and an exhaust pipe is installed on the inner surface of the curved block 1.
[0009] Preferably, the drive assembly includes a second support frame, which is installed on the upper end of the silicon carbide rod furnace shell. A motor is installed inside the second support frame, and a gear is fixedly connected to the output end of the motor via a coupling.
[0010] Preferably, the scraping assembly includes a toothed ring, which is installed on the upper end of the silicon carbide rod furnace shell. A scraper is installed on the inner surface of the toothed ring. A curved block two is installed on the upper end of the silicon carbide rod furnace shell, and an air inlet pipe is installed on the inner surface of the curved block two.
[0011] Preferably, the collecting component includes a fixed shell, which is installed at the rear end of the silicon carbide rod furnace shell. A collecting box is slidably connected to the bottom wall of the inner cavity of the fixed shell, and a handle is installed at the rear end of the collecting box.
[0012] Preferably, the outer surface of the gear meshes with the outer surface of the gear ring, and the lower end of the gear is rotatably connected to the upper end of the silicon carbide rod furnace shell.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This device, through its designed support and separation components, can separate impurities from gases, allowing for the separate collection of impurities. Impurities generated during the operation of the silicon carbide rod are often small particles that flow with the rising airflow. When the rising airflow carrying impurities impacts the curved surface block, the impurities rapidly detach from the airflow due to a sudden loss of kinetic energy. Even micron-sized particles can be effectively captured, significantly improving impurity separation. It eliminates the need for complex filter membranes and adsorbents, thus reducing manufacturing costs and avoiding problems such as filter material clogging and aging. Maintenance only requires periodic cleaning of impurities accumulated on the solid surface, eliminating the need for frequent consumable replacements and greatly reducing operation and maintenance costs and downtime.
[0015] 2. This device, through its designed drive, scraping, and collection components, can collect all impurities into the collection box. In subsequent operations, only periodic cleaning of the collection box is required, reducing cleaning steps and labor input, significantly shortening downtime for maintenance, and lowering the manpower and time costs of operation and maintenance. At the same time, the impurities concentrated in the collection box can be directly measured by weight or volume through a unified container, which can intuitively reflect the operating status of the silicon carbide rod, more accurately judge the degree of equipment wear, provide early warning of maintenance needs, and avoid sudden failures.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Example 1, as Figure 1 As shown, a silicon carbide rod impurity collector includes a support assembly 1, a separation assembly 2 mounted on the upper part of the support assembly 1, a driving assembly 3 mounted on the upper part of the support assembly 1, a scraping assembly 4 mounted on the upper part of the support assembly 1, a collection assembly 5 mounted at the rear of the support assembly 1, and a plurality of silicon carbide rod bodies 6 mounted in the inner cavity of the support assembly 1.
[0025] When implementing this solution, the operator first starts the silicon carbide rod body 6, which generates high temperature and operates. When the silicon carbide rod body 6 is operating, impurities are generated. These impurities are small in size and will float and rise with the rising airflow generated by the silicon carbide rod body 6. When the rising airflow hits the separation component 2, the impurities will separate from the airflow. The airflow is then discharged from the separation component 2, while the impurities remain in the separation component 2.
[0026] At this point, the operator can start the drive component 3 to drive the scraping component 4 to rotate, so that the scraping component 4 scrapes the impurities in the separation component 2 into the inclined groove of the support component 1, and then slides into the collection component 5 for collection. Subsequently, the weight or volume of the impurities in the collection component 5 can be directly measured through a unified container, thereby intuitively reflecting the operating status of the silicon carbide rod, more accurately judging the degree of equipment wear, providing early warning of maintenance needs, and avoiding sudden failures.
[0027] Specifically, in order to separate gases from impurities, such as Figure 2 As shown, in this scheme, the support component 1 includes a silicon carbide rod furnace shell 11, and support legs 12 are fixedly connected to the four corners of the lower end of the silicon carbide rod furnace shell 11. A rotating door 13 is installed in the inner cavity of the silicon carbide rod furnace shell 11, and a handle 14 is installed on the left end of the rotating door 13.
[0028] For further details, please refer to [link / reference]. Figure 3 and Figure 4 The separation component 2 includes a support frame 21. Both support frames 21 are installed on the upper end of the silicon carbide rod furnace shell 11. The two support frames 21 are close to each other and are jointly installed with a closed shell 22. A curved block 23 is installed on the upper end of the closed shell 22. An exhaust pipe 24 is installed on the inner surface of the curved block 23.
[0029] When implementing this solution, the operator first starts the silicon carbide rod body 6, causing it to generate high temperature and operate. During the operation of the silicon carbide rod body 6, impurities are generated. These impurities are small in size and will float and rise with the rising airflow generated by the silicon carbide rod body 6, flowing from the air inlet pipe 44 into the support frame 21. When the rising airflow hits the curved block 23, the impurities will separate from the airflow. Then the airflow will be discharged from the exhaust pipe 24, while the impurities will remain in the closed shell 22.
[0030] Example 2, based on Example 1, can collect scattered impurities together.
[0031] Specifically, in order to collect scattered impurities together, such as Figure 3 and Figure 4 As shown, in this scheme, the drive component 3 includes a second support frame 31, which is installed on the upper end of the outer shell 11 of the silicon carbide rod electric furnace. A motor 32 is installed in the inner cavity of the second support frame 31, and a gear 33 is fixedly connected to the output end of the motor 32 through a coupling.
[0032] For further details, please refer to [link / reference]. Figure 5 The scraping component 4 includes a toothed ring 41, which is installed on the upper end of the silicon carbide rod furnace shell 11. A scraper 42 is installed on the inner surface of the toothed ring 41. A curved block 43 is installed on the upper end of the silicon carbide rod furnace shell 11, and an air inlet pipe 44 is installed on the inner surface of the curved block 43.
[0033] For further details, please refer to [link / reference]. Figure 6 The collecting component 5 includes a fixed shell 51, which is installed at the rear end of the outer shell 11 of the silicon carbide rod electric furnace. A collecting box 52 is slidably connected to the bottom wall of the inner cavity of the fixed shell 51, and a handle 53 is installed at the rear end of the collecting box 52.
[0034] For further details, please refer to [link / reference]. Figure 4 and Figure 5 The outer surface of gear 33 meshes with the outer surface of gear ring 41, and the lower end of gear 33 is rotatably connected to the upper end of silicon carbide rod electric furnace shell 11.
[0035] When this solution is implemented, the operator can start the motor 32 to drive the gear 33, gear ring 41, and scraper 42 to rotate. The scraper 42 will scrape the impurities in the support frame 21 into the inclined groove of the silicon carbide rod furnace shell 11, and then slide them into the collection box 52 for collection. Subsequently, the weight or volume of the impurities in the collection box 52 can be directly measured through a unified container, so as to intuitively reflect the operating status of the silicon carbide rod, more accurately judge the degree of equipment wear, provide early warning of maintenance needs, and avoid sudden failures.
[0036] Meanwhile, after impurities fall, the curved surface of the air inlet pipe 44 can effectively prevent impurities from falling back into the outer shell 11 of the silicon carbide rod electric furnace, while the design of the curved block 43 allows all impurities to gather in the groove of the support frame 21, so that the scraper 42 can scrape all the impurities into the collection box 52.
[0037] In summary, the implementation process of this utility model is as follows:
[0038] The operator first starts the silicon carbide rod body 6, which generates high temperature and operates. When the silicon carbide rod body 6 is operating, impurities are generated. These impurities are small in size and will float and rise with the rising airflow generated by the silicon carbide rod body 6. They flow from the air inlet pipe 44 into the support frame 21. When the rising airflow hits the curved block 23, the impurities will separate from the airflow. Then the airflow is discharged from the exhaust pipe 24, while the impurities remain in the closed shell 22.
[0039] At this point, the operator can start the motor 32 to drive the gear 33, gear ring 41, and scraper 42 to rotate, so that the scraper 42 scrapes the impurities in the support frame 21 into the inclined groove of the silicon carbide rod furnace shell 11, and then slides into the collection box 52 for collection. Subsequently, the weight or volume of the impurities in the collection box 52 can be directly measured through a unified container, thereby intuitively reflecting the operating status of the silicon carbide rod, more accurately judging the degree of equipment wear, providing early warning of maintenance needs, and avoiding sudden failures.
[0040] It should be noted that the specific installation methods, circuit connection methods, and control methods of the motor 32, silicon carbide rod, etc. used in this utility model are all conventional designs, and will not be described in detail here.
