A heating furnace for use with cleanable molybdenum disilicide heating elements

Abstract

This utility model discloses a heating furnace for cleaning waste molybdenum disilicide heating elements, belonging to the field of heating equipment technology. This solution utilizes an electrical guide rail within a transverse chute and a vertical displacement slide rod to ensure precise alignment of the cleaning mechanism with the heating strip. The combined effect of mechanical scraping by the high-speed rotation of extended scraper bristles and high-pressure airflow from a high-pressure blowing pipe powerfully removes oxide scale, debris, and other impurities from the heating strip surface. Compared to a single cleaning method, the cleaning efficiency and effectiveness are significantly improved. Simultaneously, the extended scraper bristles contact the serrated transverse strips, and the serrated structure promptly scrapes away residual waste adhering to the bristles, achieving self-cleaning and preventing subsequent cleaning effects from being affected by residual impurities. This ensures the stability of the long-term cleaning effect and effectively compensates for the shortcomings of existing technologies in terms of equipment durability and economy, providing strong support for the efficient reuse of molybdenum disilicide materials.

Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a heating furnace for a cleanable molybdenum disilicide electric heating element. Background Technology

[0002] Molybdenum disilicide heating elements are high-performance resistance heating materials with advantages such as high temperature resistance, oxidation resistance, and long life. They are widely used in high-temperature industrial furnaces, laboratory muffle furnaces, semiconductor manufacturing, and other fields. Heating furnaces are high-temperature equipment that use such heating elements as the core heating element and are suitable for processes such as ceramic sintering, glass melting, and metal heat treatment.

[0003] A rapid heating molybdenum disilicide electric furnace, Chinese Patent No. CN221259497U, describes a mechanism that allows for the upward movement of a lever, which in turn moves a locking block upwards. This causes a spring to contract on the surface of the sliding rod. Once the locking block disengages from the inner cavity of the locking slot, pulling the handle removes the molybdenum disilicide heating rod. This interlocking structure allows for quick and easy installation and removal of the heating rod, minimizing time wasted on maintenance and replacement, and improving the efficiency of the molybdenum disilicide electric furnace maintenance.

[0004] Molybdenum disilicide is synthesized from rare metal molybdenum powder and silicon powder through a self-propagating reaction. Due to the high cost of molybdenum powder raw materials and the complex synthesis process, improving the utilization rate of molybdenum disilicide is particularly important. If the waste rods generated during the production process and some of the rods after the kiln is used can be reused, the effective utilization rate of molybdenum disilicide can be significantly improved. However, these rods have accumulated oxide scale, debris and other impurities on their surface due to long-term high-temperature operation. If they are to be reused, these impurities must be removed first. However, cleaning the oxide scale, debris and other impurities on the surface of the rods is extremely difficult. Based on this, we designed a special cleaning device that combines the characteristics of the material. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4This utility model provides a heating furnace solution for a cleanable molybdenum disilicide heating element: It includes a heating furnace body 1, a sealing plate 2 hinged to the front end of the heating furnace body 1, multiple heating strips 3 symmetrically fixed to the left and right inner walls of the heating furnace body 1, a transverse sliding groove 4 on the front side of the heating furnace body 1, an electrical guide rail 5 slidably connected to the inner end of the transverse sliding groove 4 (model HIWINKK6010C-400A1-F0 linear module can be selected), and a vertical displacement slide rod 6 installed at the output end of the electrical guide rail 5. The vertical displacement slide rod 6 is close to... A hollow linkage chamber 7 is fixedly connected to one end of the heating furnace equipment body 1. A motor 10 is fixedly connected to the front end of the hollow linkage chamber 7. The model can be a Panasonic MSMD022G1U DC servo motor. Several extended scraping brush bristles 11 arranged in a ring and equidistant are fixedly connected to the outer end of the motor 10. Multiple high-pressure blowing pipes 8 arranged in a ring and equidistant are fixedly connected to the outer end of the hollow linkage chamber 7. A high-pressure air pump is built into the hollow linkage chamber 7. The model can be a Qihai VAY880-12V micro high-pressure air pump. A dust collection bottom chamber 15 is opened on the lower inner wall of the heating furnace equipment body 1.

[0018] Please see Figures 2-4 The high-pressure blowing pipe 8 and the extended scraper brush 11 are arranged horizontally front and back. The high-pressure blowing pipe 8 and the extended scraper brush 11 are respectively connected to multiple heating bars 3. The upper end of the dust bottom chamber 15 is slidably connected to the sliding chamber top cover plate 16. The upper front side of the sliding chamber top cover plate 16 is fixedly connected to the metal matching strip 13. The lower rear side of the hollow linkage chamber 7 is fixedly connected to the electromagnetic cross bar 12. The model can be MFZ1-2.5 DC electromagnet. The electromagnetic cross bar 12 and the metal matching strip 13 are magnetically connected. The lower right side of the heating furnace equipment body 1 is fixedly connected to the pump 14. The model can be KNFN86KTE micro vacuum diaphragm pump. The output end of the pump 14 is connected to the dust bottom chamber 15.

[0019] The pump 14 on the lower right side of the heating furnace equipment body 1 is started, and its output end is connected to the dust collection bottom chamber 15. With the adsorption effect of the dust suction bottom plate 18, the waste collected in the dust collection bottom chamber 15 is quickly discharged or transported to the designated collection device to complete the entire waste cleaning process. After the cleaning is completed, the electromagnetic horizontal bar 12 is de-energized, the vertical displacement slide bar 6 moves outward, and the sliding chamber top cover plate 16 is reset to close the dust collection bottom chamber 15. The equipment can then re-enter the heating operation state.

[0020] Please see Figures 2-3 A dust collection base plate 18 is fixedly connected to the lower inner wall of the dust collection bottom chamber 15. Multiple extended scraping brush bristles contact serrated horizontal strips 17 are fixedly connected to the upper end of the dust collection base plate 18. The multiple extended scraping brush bristles contact serrated horizontal strips 17 are arranged horizontally at equal intervals, and the extended scraping brush bristles contact serrated horizontal strips 17 and the extended scraping brush bristles 11 are in contact with each other.

[0021] At the same time, as the hollow linkage chamber 7 moves laterally, the extended scraper bristles 11 and the multiple extended scraper bristle contact sawtooth horizontal bars 17 on the upper end of the dust collection base plate 18 on the lower inner wall of the dust collection bottom chamber 15 are horizontally and equidistantly arranged and contact each other. The sawtooth structure can scrape off the residual waste material attached to the extended scraper bristles 11, ensuring that the bristles are clean.

[0022] The working principle of this utility model is as follows: In this scheme, the heating furnace equipment body 1 is the main body of the device. During operation, the sealing plate 2 is closed first to form a closed space inside the furnace. Multiple heating bars 3 on the left and right inner walls are energized and heated to achieve the heating operation of the molybdenum disilicide heating element inside the furnace. When it is necessary to clean the waste on the surface of the heating bar 3, before the cleaning process, the electromagnetic cross bar 12 on the rear side of the lower end of the hollow linkage chamber 7 is energized to generate magnetism, which attracts the metal matching bar 13 on the front side of the upper end of the sliding chamber top cover plate 16, thereby driving the sliding chamber top cover plate. 16 slides along the upper end of the dust collection bottom chamber 15, opening the dust collection bottom chamber 15. Under the action of gravity and airflow, the stripped waste falls into the dust collection bottom chamber 15 through the opened sliding chamber top cover 16. The electric guide rail 5 in the transverse slide 4 is activated, driving the vertical displacement slide rod 6 to move laterally. At the same time, the vertical displacement slide rod 6 can adjust the position of the hollow linkage chamber 7, so that the cleaning mechanism is precisely aligned with the heating strip 3. The motor 10 at the front end of the hollow linkage chamber 7 drives several extended scraping bristles 11 arranged in a ring at equal intervals to rotate at high speed. The hollow linkage chamber 7 rotates, and multiple high-pressure blowing pipes 8 at its outer end provide air supply through a built-in high-pressure air pump. Through the combined action of mechanical scraping and high-pressure airflow, oxide scale, debris, and other waste materials on the surface of the heating strip 3 are peeled off. Simultaneously, as the hollow linkage chamber 7 moves laterally, the extended scraping brush bristles 11 contact the multiple extended scraping brush bristles and serrated horizontal bars 17 on the upper end of the dust collection base plate 18 on the lower inner wall of the dust collection chamber 15. These serrated structures are horizontally and equidistantly arranged and contact each other. The serrated structure can scrape away the waste materials on the extended scraping brush bristles 11. After removing any remaining waste, ensuring the brush bristles are clean, the pump 14 on the lower right side of the heating furnace body 1 is started. Its output end is connected to the dust collection bottom chamber 15. With the adsorption effect of the dust suction plate 18, the waste collected in the dust collection bottom chamber 15 is quickly discharged or transported to the designated collection device, completing the entire waste cleaning process. After cleaning, the electromagnetic horizontal bar 12 is de-energized, the vertical displacement slide bar 6 moves outward, and the sliding chamber top cover 16 resets to close the dust collection bottom chamber 15. The equipment can then re-enter the heating operation state.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
