Description

Technical Field

[0001] This application belongs to the technical field of auxiliary devices for heat treatment furnaces, and in particular relates to a heat treatment platform mechanism and a heat treatment device equipped with the platform mechanism. Background Technology

[0002] In trolley heat treatment equipment, the tubes need to be arranged on a special platform for the heat treatment furnace. As the platform is fed into the heat treatment furnace, the furnace opening sealing requirements are high, and the temperature of the tubes inside the furnace needs to be monitored at all times, as well as the gas supply to the tubes.

[0003] In existing heat treatment processes, the support structure for the supporting tubes is integrally connected. After repeated heating and cooling cycles within the furnace, this support structure undergoes severe thermal expansion and deformation, directly leading to an inability to stably support the tubes for horizontal placement and significantly impacting tube transport. Furthermore, due to design flaws in the platform structure, the furnace opening seal is poor during heat treatment; it may even prevent the proper supply of gas to the tubes within the furnace, affecting the quality of tube production. Summary of the Invention

[0031] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] This embodiment proposes a heat treatment platform mechanism, such as... Figure 1-2 As shown, the system includes a base frame 10, a support assembly 20 placed on the base frame 10, and a sealing assembly 30. The base frame 10 is a platform frame, comprising a base plate and a rectangular frame fixed integrally with the periphery of the base plate. A surrounding frame is also provided on the top surface of the frame to form a rectangular recessed frame with an opening at the top. The support assembly 20 is mainly used for placing pipes and is configured inside the base frame 10. It includes several support beams 21 arranged parallel to each other along the width direction of the base frame 10. That is, the length of the support beams 21 is set along the width direction of the base frame 10. All pipes are placed parallel to each other along their length direction on the support assembly formed by the parallel support beams 21. The length of the pipes is perpendicular to the length of the support beams 21. The support beams 21 and the base frame 10 are movably connected, which can reduce the expansion and deformation of the pipes during alternating hot and cold treatment in the heat treatment furnace, improve the deformation resistance of the suspended support beams 21, extend their service life, and ensure the stability of pipe transportation.

[0033] Specifically, the base frame 21 is provided with several pin seats 22 fixed to its base plate and fixing seats 23 that are inserted into the pin seats 22. The width of the pin seats 22 is arranged parallel to the length of the base frame 10, and the pin seats 22 are provided with pin holes that mate with the fixing seats 23. The length of the fixing seat 23 is perpendicular to the width of the pin seats 22, that is, the fixing seat 22 is constructed as a T-shaped structure, and its lower part is inserted into the pin hole on the pin seat 23. The upper end face of the fixing seat 22 is provided with a groove for securing the bottom width direction of the support beam 21.

[0034] The support beam 21 is constructed as a horizontal beam with both its upper and lower surfaces flush. One end of its upper surface has a stop block to prevent the pipe material from falling; the other end has a downward-sloping surface to facilitate material flow during unloading. The support beam 21 is suspended and parallel to each other inside the base frame 10 through the cooperation of the fixing seat 23 and the pin seat 10. The height of the support beam 21 is higher than the height of the sealing assembly 30, allowing the pipe material to be freely placed on the support beam 21 without interfering with the perimeter of the platform frame.

[0035] Furthermore, the base frame 21 and the fixed seat 23, as well as the fixed seat 23 and the pin seat 22, are movably connected to each other. Each base frame 21 is equipped with at least two pin seats 22, and each pin seat 22 is equipped with a fixed seat 23. By adopting a movably connected pipe support structure, the deformation impact between the base frame 21 and the fixed seat 23, and between the fixed seat 23 and the pin seat 22, is minimized, ensuring both support strength and stable pipe placement.

[0036] Furthermore, the sealing assembly 30 is mainly used for sealing with the heat treatment furnace. It is disposed on the perimeter frame of the base frame 21 and includes a sealing gasket 31 and a tray frame 32 for fixing the sealing gasket 31. The tray frame 32 is movably engaged with the base frame 10 through a tray bracket 33. That is, at the corners of the base frame 10, there are slots for inserting the tray bracket 33. To ensure airtightness, refractory material is filled in the gap between the slot and the tray bracket 33, which can improve the safety of the connection without affecting production quality. The top of the tray bracket 33 is directly connected to the lower end face of the tray frame 32, and its lower end face is connected to the base frame 10 through a slot. The tray frame 32 is a rectangular and continuously arranged planar frame, mainly used to fix the sealing gasket 31. In this embodiment, the sealing gasket 31 is a sealing rope commonly used in the art, which is made of high-temperature resistant fiber. The sealing rope can fit against the heat treatment furnace inlet to form a sealing surface.

[0037] During high-temperature production in the heat treatment furnace, the support beam 21 and the pallet frame will be affected by the temperature at different stages, and will continuously expand and contract. The expansion and contraction will occur within the connection range between the pin seat 22 and the fixed seat 23, and between the pallet bracket 33 and the slot, without affecting the deformation of the support beam 21 and the platform sealing surface, thus ensuring the safety and reliability of the heat treatment environment.

[0038] Furthermore, on the platform structure, the base frame 10 is also provided with several pipe fittings 40 for thermocouples to pass through and pipe fittings 50 for pipe materials to pass through. The pipe fittings 40 and 50 are arranged on the same side at intervals, that is, on the side close to one end of the slope of the support beam 10, and adjacent pipe fittings 40 and 50 are placed on both sides of any support beam 10.

[0039] like Figure 3 As shown, the fitting 40 is constructed in an L-shape, including a tube body 41 and a sealing plug 42. The upper end of the tube body 41 is suspended inside the base frame 10, and its lower end passes through the bottom plate of the base frame 10 and extends outward. The sealing plug 42 mates with the outwardly extending end of the tube body 41. The thermocouple enters the tube body 41 from the sealing plug 42 end, then enters the base frame 10, and is then directly bonded to the tube for operation; this is a conventional operation in the art.

[0040] like Figure 4 As shown, the second pipe fitting 50 is constructed as a curved pipe, including a second pipe body 51, a sealing joint 52, a felt block 53, and a joint cover 54. The upper end of the second pipe body 51 is built into the inner side of the base frame 10, and its lower end passes through the side wall of the base frame 10 and extends outward. The sealing joint 52 is located at its outwardly extending end. The inner side of the sealing joint 52 is provided with a high-temperature resistant sealing felt block 53 that contacts the end of the second pipe body 51, and the sealing joint 52 is threadedly connected to the second pipe body 51. At the end of the sealing joint 52, a joint cover 54 is also provided, which is threadedly engaged with it. The felt block 53 is installed inside the second pipe body 51. After the fitting is first bound to a thermocouple passing through the adjacent first pipe body 41 inside the base frame 10, the fitting passes through the second pipe body 51 and exits from the sealing joint 52 end, extending outside the base frame 10 to connect with an external gas pipeline. Multiple layers of high-temperature resistant sealing felt blocks 53 are arranged inside the sealing joint 52. A slit can be opened at the center of the felt block 53 to seal pipes of different sizes and specifications. This slit is a common structure in the field and is omitted here.

[0041] As can be seen from the above analysis, both the support component 20 and the sealing component 30 are designed as insert-type, non-fixed limiting structures. Refractory materials can be used to fill the gaps at the connection points, and the overall structure has sufficient sealing and safety. The furnace interior is kept under slight positive and negative pressure, and the safety atmosphere conditions meet the requirements. Based on the expansion of the components, it fully meets the requirements for the strength of the support structure and the flatness of the sealing surface of the furnace platform mechanism. Therefore, it can also replace the platform structure used in other heat treatment furnaces and can be widely applied. In addition, the thermocouples passing through the tubing in fitting 40 and fitting 50 passing through the tubing have one end inside the furnace and the other end outside the furnace. The tubing exits from inside the furnace and connects to the external pipeline after passing through a sealing joint. Both fittings 40 and 50 are left outside the furnace, ensuring the airtightness of the furnace and the safety of the equipment.

[0042] A heat treatment apparatus, equipped with the platform mechanism described above.

[0043] The heat treatment platform mechanism designed in this application employs a movable pipe support structure to minimize the impact of deformation, ensuring both support strength and stable pipe placement. The optimized platform structure improves airtightness, guaranteeing equipment safety and allowing for the timely delivery of gas into the furnace. This application also proposes a heat treatment device equipped with this platform mechanism.

[0044] The embodiments of this application have been described in detail above. These descriptions are merely preferred embodiments and should not be construed as limiting the scope of this application. All equivalent variations and modifications made within the scope of this application should still fall within the patent coverage of this application.
