Description

Technical Field

[0001] This utility model relates to the field of temperature control furnace technology, and in particular to a temperature control furnace for heat treatment of fine-grained high-temperature molybdenum-copper-based composite materials. Background Technology

[0002] Fine-grained high-temperature molybdenum-copper matrix composites have important applications in high-tech fields such as aerospace and electronics. Their heat treatment process requires stringent conditions regarding temperature and atmosphere to ensure optimal material performance. While existing heat treatment furnaces have continuously improved in terms of temperature control, heating, and atmosphere creation, they often neglect the issue of waste gas emissions generated during the heat treatment process. When heat treating these composite materials, waste gases containing particulate matter, volatile organic compounds, and potentially harmful metal compounds are generated inside the furnace. Direct discharge through exhaust vents not only pollutes the surrounding environment, failing to meet increasingly stringent environmental protection requirements, but may also deteriorate air quality in the workshop, affecting the health of operators and the normal operation of other equipment. Utility Model Content

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a filter box is fixedly installed at the end of the exhaust pipe away from the furnace body. The filter box, together with the supporting filter frame and the activated carbon layer, can filter the exhaust gas generated during the heat treatment process, which contains particulate matter, volatile organic compounds and potentially harmful metal compounds.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1-4This utility model provides a technical solution: a temperature-controlled furnace for heat treatment of fine-grained high-temperature molybdenum-copper-based composite materials, comprising a furnace body 1 and a furnace door 2. An inlet pipe 3 and an exhaust pipe 5 are fixedly installed on the outer surface of the furnace body 1. A solenoid valve 4 and a solenoid valve 6 are installed on the inlet pipe 3 and the exhaust pipe, respectively. A heating element 10 is installed on the inner wall of the furnace body 1. A controller 9 is fixedly installed on one side of the furnace body 1 located near the inlet pipe 3. A filter box 7 is fixedly installed at the end of the exhaust pipe 5 away from the furnace body 1. A connecting pipe 8 is fixedly installed on the other side of the filter box 7. A groove is formed on the top of the filter box 7. 13. A groove 14 is opened at the bottom of the groove 13. A bearing filter frame 15 is inserted inside the groove 14. A filter hole 18 is opened on the side of the bearing filter frame 15 facing the exhaust pipe 5. An activated carbon layer 17 is provided on the inner side of the bearing filter frame 15. A connecting plate 16 is fixedly installed on the top of the bearing filter frame 15. A fixing block 19 is fixedly installed on the outer surface of the filter box 7. A screw 20 is connected to the inside of the fixing block 19. A knob 22 is fixedly installed on the top of the screw 20. A rotating connecting block 21 is connected to the surface of the screw 20. The locking block 21 is locked on the connecting plate 16.

[0023] like Figure 3 As shown, a fan 26 is installed inside the filter box 7. The fan 26 is located on the side close to the connecting pipe 8. This allows the exhaust gas discharged from the furnace to pass through the filter box 7 more smoothly and quickly for filtration and purification, speeds up the exhaust gas treatment speed, improves the working efficiency of the entire exhaust filtration system, ensures that the exhaust gas can be discharged in time, and avoids accumulation in the furnace that affects the heat treatment process.

[0024] like Figure 3 As shown, a sealing gasket 31 is provided at the bottom of the groove 13. The sealing gasket 31 is located between the connecting plate 16 and the groove 13. This effectively fills the gap between the two, preventing exhaust gas from leaking from the connection between the bearing filter frame 15 and the filter box 7, and ensuring the sealing of the filter box 7.

[0025] like Figure 3 and Figure 4 As shown, a U-shaped retaining strip 32 is fixedly installed on the outer surface of the filter frame 15. A U-shaped groove 25 is opened on the inner wall of the filter box 7 corresponding to the position of the U-shaped retaining strip 32. The U-shaped retaining strip 32 is inserted into the U-shaped groove 25. This makes the installation of the filter frame 15 in the filter box 7 more stable and the positioning more accurate. During the operation of the equipment, even if it is impacted by the airflow generated by the fan 26 or by the vibration generated during filtration, the filter frame 15 can be kept in a stable working position to ensure the continuous and stable operation of the filtration work.

[0026] like Figure 4As shown, a chip discharge port 27 is opened on one side of the filter hole 18 on the inner bottom surface of the filter box 7. A collection pipe 28 is fixedly installed at the bottom of the filter box 7. A slag discharge port 29 is set at the bottom of the collection pipe 28. A sealing cover 30 is set at the slag discharge port 29. This facilitates the collection of particulate matter, impurities, etc. intercepted from the exhaust gas during the filtration process. The accumulated waste residue can be cleaned by opening the sealing cover 30 periodically.

[0027] like Figure 2 As shown, a tray 11 is provided on the inner bottom surface of the furnace body 1, and a motor 12 is fixedly installed on the outer bottom surface of the furnace body 1. The output end of the motor 12 passes through the bottom of the furnace body 1 and is fixedly installed on the bottom of the tray 11. Here, the motor 12 drives the tray 11 to rotate, which can make the fine-grained high-temperature molybdenum copper-based composite material placed on the tray 11 heat more evenly, avoid the situation that the material has local temperature differences due to heating in a fixed position, and help improve the performance consistency of the material after heat treatment.

[0028] like Figure 3 and Figure 5 As shown, a limiting protrusion 24 is fixedly installed at the bottom of the locking block 21. A limiting groove 23 is opened on the connecting plate 16 at the position corresponding to the limiting protrusion 24. The limiting protrusion 24 is inserted into the limiting groove 23. This further enhances the reliability of the locking block 21 in fixing the carrier filter frame 15, and prevents the locking block 21 from shifting or loosening due to external forces (such as vibration generated by the operation of the fan 26) during the use of the carrier filter frame 15, so as not to affect the stable fixing effect of the carrier filter frame 15.

[0029] The usage and working principle of this device are as follows: First, place the fine-grained high-temperature molybdenum-copper-based composite material to be heat-treated on the tray 11 at the bottom of the furnace body 1. Close the furnace door 2 to ensure the furnace body 1 is sealed. Then, set the parameters required for the heat treatment process, such as temperature control parameters and heating time, through the controller 9. Simultaneously, prepare the exhaust filtration system and start the heating element 10 to heat the material inside the furnace body 1. Perform heat treatment operations such as heating and heat preservation according to the set process parameters. During this process, if a specific atmosphere (such as inert gas) needs to be introduced into the furnace, the controller 9 can open the solenoid valve 4 on the inlet pipe 3 to allow gas to enter the furnace and create a suitable atmosphere. If the gas inside the furnace needs to be discharged, open the solenoid valve 6 on the exhaust pipe 5. When the solenoid valve 6 is opened, the exhaust gas generated inside the furnace enters the filter box 7 from the exhaust pipe 5 under the action of the fan 26. The exhaust gas will first impact the side of the support filter frame 15 facing the exhaust pipe 5. At this time, the filter holes 18 opened on the support filter frame 15 can initially intercept large particulate matter in the exhaust gas, preventing it from entering the deep interior of the filter box 7 and causing blockage and other problems.Next, the exhaust gas passes through the filter holes 18 and enters the inner side of the support filter frame 15. After passing through the activated carbon layer 17, the activated carbon, with its porous structure and strong adsorption properties, adsorbs and filters volatile organic compounds, harmful metal compounds, and other fine particulate pollutants in the exhaust gas, thus purifying the exhaust gas. Under the continuous action of the fan 26, the purified gas continues to flow towards the side closer to the connecting pipe 8, and is finally discharged into the external environment through the connecting pipe 8. During the filtration process, the intercepted particulate matter, impurities, and other waste residues will, under the action of gravity, pass through the filter holes located on the bottom surface of the filter box 7. The slag discharge port 27 on one side of the filter box 7 allows the slag to fall into the collection pipe 28. When the slag accumulates to a certain level, the sealing cover 30 at the slag discharge port 29 can be opened for cleaning to keep the inside of the filter box 7 clean and ensure that the filtration work can be carried out continuously and effectively. During the entire heat treatment process, the motor 12 located on the bottom surface of the furnace body 1 runs continuously. Its output end drives the tray 11 to rotate, so that the fine-grained high-temperature molybdenum copper-based composite material placed on the tray 11 can continuously change its position. All parts can receive the heat emitted by the heating element 10 evenly, avoiding uneven local temperature of the material caused by heating in a fixed position. In this case, to ensure that the material is heat-treated in a uniform temperature environment, thereby improving the performance and quality of the material after heat treatment, when it is necessary to replace the activated carbon layer 17 and clean the carrier filter frame 15, turn the knob 22. The knob 22 drives the screw 20 to rotate in the fixed block 19 and moves the locking block 21 upward. When the limiting protrusion 24 at the bottom of the locking block 21 disengages from the limiting groove 23, turn the locking block 21, and then remove the carrier filter frame 15 from the slot 14. After replacing the activated carbon layer 17 and cleaning the carrier filter frame 15, insert the carrier filter frame 15 into the slot 14, and insert the U-shaped locking strip 32. Initial positioning is achieved within the U-shaped groove 25 on the inner wall of the filter box 7. Then, by rotating the knob 22, the screw 20 is driven to rotate. The locking block 21 connected to the surface of the screw 20 will be inserted into the limiting groove 23 on the connecting plate 16 by the up and down movement of the screw 20. At the same time, the locking block 21 tightly locks the connecting plate 16, and the sealing gasket 31 at the bottom of the groove 13 can ensure the sealing between the carrying filter frame 15 and the filter box 7, thereby achieving stable installation and good sealing of the carrying filter frame 15 in the filter box 7, ensuring that it can play a stable role in the process of filtering exhaust gas.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
