Description

Technical Field

[0001] This utility model relates to the field of quenching furnace technology, and in particular to a quenching furnace used in the production of pressure vessels. Background Technology

[0002] A pressure vessel is a sealed container capable of withstanding pressure, typically containing gas or liquid. It is widely used in industrial production, playing a crucial role in numerous fields such as chemical, petroleum, energy, pharmaceutical, and food industries. These containers generally need to operate under specific pressure and temperature conditions, ensuring the safety and stability of the contained medium. A quenching furnace used in pressure vessel production is an industrial furnace specifically designed for quenching pressure vessel materials or components. Quenching is a heat treatment process whose basic function is to heat a material above its critical temperature, hold it at that temperature for a certain time, and then cool it at an appropriate rate, thereby altering the material's microstructure and improving its mechanical properties, such as hardness, strength, and toughness. For pressure vessels, components treated in a quenching furnace can better withstand pressure, improving the overall quality and safety of the vessel.

[0003] In existing technologies, traditional quenching furnaces used in pressure vessel manufacturing involve slowly feeding a fixture or placement tool containing the workpiece into the furnace. During placement, it is crucial to ensure the workpiece is positioned appropriately within the furnace to guarantee uniform heating. After quenching is complete, the heated workpiece must be manually moved quickly to the quenching area for further quenching.

[0004] However, in the existing technology, traditional quenching furnaces usually require manual removal of the pressure vessel from the furnace for the next quenching process, which is not only dangerous but also requires additional manual steps and is inefficient. Therefore, a quenching furnace for pressure vessel production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quenching furnace for pressure vessel production, which aims to improve the problem of low work efficiency caused by additional processes in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quenching furnace for pressure vessel production includes two bases, with a furnace body fixedly connected to the top of the two bases. Two sliding grooves are fixedly connected inside the furnace body, and sliding plates are slidably connected inside the sliding grooves. A rotating plate is rotatably connected to the bottom of the sliding plates, and a placement box is fixedly connected to the top of the sliding plates. A clamping assembly for fixing the pressure vessel is provided inside the placement box. A conduit is fixedly connected inside the furnace body, and a spring is sleeved on the outside of the conduit.

[0008] As a further description of the above technical solution:

[0009] The sliding plate is slidably connected to the outside of the guide tube, one end of the spring is fixedly connected to the inside of the furnace body, and the other end of the spring is fixedly connected to the outside of the sliding plate.

[0010] As a further description of the above technical solution:

[0011] A connecting strip is fixedly connected to the outside of the furnace body, and a connecting plate is rotatably connected to the inside of the connecting strip. A furnace cover is fixedly connected to the rear side of the connecting plate, and a pull ring is fixedly connected to the front side of the furnace cover.

[0012] As a further description of the above technical solution:

[0013] A U-shaped plate is fixedly connected to the rear side of the furnace cover, and a pull bar is rotatably connected inside the U-shaped plate. The bottom of the pull bar is rotatably connected to the bottom of the rotating plate.

[0014] As a further description of the above technical solution:

[0015] A heating device is fixedly connected to the rear side of the furnace body, and a gas outlet pipe is fixedly connected to the top of the furnace body.

[0016] As a further description of the above technical solution:

[0017] The clamping assembly includes two limiting slide rods, which are externally fixedly connected to the inside of the placement box, and two clamping strips are slidably connected to the external side of the limiting slide rods.

[0018] As a further description of the above technical solution:

[0019] The placement box has two internal threaded screws, and the external screws are fixedly connected with nuts.

[0020] As a further description of the above technical solution:

[0021] The two rotating screws are externally rotatably connected to the outside of the clamping bar, and the outside of the nut is in contact with the outside of the placement box.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the furnace cover is opened by pulling the pull ring to rotate the furnace cover and open the inlet of the base. At the same time, pulling the U-shaped plate causes the pull bar to rotate, thereby causing the rotating plate to pull the sliding plate to slide inside the slide groove. Simultaneously, the top placement box and the internal pressure vessel slide out of the furnace body, which facilitates material unloading. Finally, the reaction force of the spring can drive the sliding plate to slide back to its original position, which is convenient for the next heating. This reduces the unloading process and time, facilitates subsequent quenching, and improves work efficiency.

[0024] 2. In this utility model, the pressure vessel is placed inside the two clamping bars. Then, the two nuts are rotated to drive the rotating screw to rotate, thereby causing the two clamping bars to slide in opposite directions, clamping the pressure vessel inside the placement box and completing the fixation. This fixation method ensures that the pressure vessel remains stable throughout the heating and quenching process, ensuring heating uniformity and improving the stability of equipment operation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a quenching furnace for pressure vessel production, comprising two bases 1, with a furnace body 2 fixedly connected to the top of the two bases 1. The two bases 1 are cuboid in shape, and their tops are fixedly connected to the furnace body 2 by welding. Two elongated sliding grooves 3 are fixedly connected inside the furnace body 2 to provide a stable sliding track, facilitating the sliding removal of the pressure vessel for subsequent quenching processes. A sliding plate 4 is slidably connected inside the chute 3. The sliding plate 4 is rectangular and its thickness is consistent with the sliding track inside the chute 3, thus ensuring sliding stability. A rotating plate 6 is rotatably connected to the bottom of the sliding plate 4. The rotating plate 6 is long and made of stainless steel and is used to pull the sliding plate 4 to slide out of the furnace body 2. A placement box 5 is fixedly connected to the top of the sliding plate 4. The placement box 5 is cuboid and is used to provide a container for the pressure vessel during quenching heating. The placement box 5 is equipped with a clamping component for fixing the pressure vessel. A conduit 15 is fixedly connected inside the furnace body 2. The conduit 15 is cylindrical and is used to limit the subsequent elastic structure to prevent deformation. A spring 16 is sleeved on the outside of the conduit 15. The spring 16 is used to provide a reaction pull to drive the sliding plate 4 to reset, thus facilitating the next use.

[0033] The sliding plate 4 is internally slidably connected to the outside of the guide tube 15. The sliding plate 4 has a through hole that matches the guide tube 15, allowing the sliding plate 4 to slide along the outside of the guide tube 15, compressing and stretching the spring 16. One end of the spring 16 is fixedly connected to the inside of the furnace body 2, and the other end of the spring 16 is fixedly connected to the outside of the sliding plate 4. The spring 16 has good elastic potential energy and can provide a reaction force to drive the sliding plate 4 and the top placement box 5 to reset. A connecting strip 11 is fixedly connected to the outside of the furnace body 2. The connecting strip 11 is rectangular. A connecting plate 12 is rotatably connected inside the connecting strip 11. The connecting plate 12 is L-shaped and connected to the inside of the connecting strip 11 through a rotating shaft. A furnace cover 13 is fixedly connected to the rear side of the connecting plate 12. The furnace cover 13 is circular, and its diameter is slightly larger than the opening diameter of the furnace body 2, which serves to seal the furnace body 2 and prevent heat loss and external impurities from entering the furnace body 2. A pull ring 14 is fixedly connected to the front side of the furnace cover 13. The pull ring 14 is circular for easy gripping by the operator. The furnace cover 13 can be easily opened or closed by pulling the pull ring 14. A U-shaped plate 8 is fixedly connected to the rear side of the furnace cover 13. A pull bar 7 is rotatably connected inside the U-shaped plate 8. The bottom of the pull bar 7 is rotatably connected to the bottom of the rotating plate 6. The U-shaped plate 8 is driven by the furnace cover 13 to pull the pull bar 7, thereby moving the rotating plate 6 and using the force of opening the furnace cover 13 to slide the pressure vessel out of the furnace body 2.

[0034] Reference Figures 1 to 2A heating device 9 is fixedly connected to the rear side of the furnace body 2. The heating device 9 contains multiple heating elements, typically made of resistance wire or other high-temperature resistant materials. These heating elements generate heat when energized, which is transferred to the interior of the furnace body 2 through thermal radiation and convection. An exhaust pipe 10 is fixedly connected to the top of the furnace body 2. The exhaust pipe 10 is cylindrical with a relatively small diameter, allowing the high-temperature gas generated inside the furnace to be discharged to the external environment. The interior of the exhaust pipe 10 is smooth, ensuring smooth gas flow. Valves are installed on the wall of the exhaust pipe 10 to control the gas discharge rate and flow rate.

[0035] Reference Figure 4 The clamping assembly includes two limiting slide rods 17, which are externally fixedly connected to the inside of the placement box 5. The limiting slide rods 17 are slender cylindrical in shape, their length matching the internal length of the placement box 5. Two clamping strips 18 are slidably connected to the outside of the limiting slide rods 17. The clamping strips 18 are block-shaped with internal holes for placing pressure vessels. Two rotating screws 19 are threadedly connected to the inside of the placement box 5. Nuts 20 are externally fixedly connected to the rotating screws 19. Rotation of the nuts 20 drives the rotating screws 19 to rotate helically. The two rotating screws 19 are externally rotatably connected to the outside of the clamping strips 18, causing the clamping strips 18 to slide. The outside of the nuts 20 contacts the outside of the placement box 5, thus limiting the nut 20 and preventing excessive rotation that could cause the pressure vessel to shift position.

[0036] Working principle: First, the operator places the pressure vessel inside the placement box 5. Then, by rotating the connecting plate 12, the furnace cover 13 is rotated to close the inlet of the furnace body 2. At this time, the heating device 9 is turned on to heat and quench the pressure vessel inside the furnace body 2. After heating is completed, the furnace cover 13 is rotated by pulling the pull ring 14 to open the inlet of the base 1. At the same time, the U-shaped plate 8 is pulled to rotate the pull bar 7, thereby causing the rotating plate 6 to pull the sliding plate 4 to slide inside the slide groove 3. Simultaneously, the placement box 5 on top and the internal pressure vessel slide out of the furnace body 2 for unloading. Finally, the reaction force of the spring 16 can drive the sliding plate 4 to slide back to its original position, facilitating the next heating. By rotating the furnace cover 13, the placement box 5 containing the pressure vessel can be slid out, reducing the manual pulling process and time of the placement box 5, facilitating subsequent quenching processes, and improving work efficiency.

[0037] Secondly, during heating, the vibration generated by the operation of the equipment can easily cause displacement of the internal pressure vessel, affecting the heating and quenching process. Therefore, when placing the pressure vessel, it is placed inside the two clamping bars 18. Then, the two nuts 20 are rotated to drive the rotating screw 19 to rotate, thereby causing the two clamping bars 18 to slide in opposite directions, clamping the pressure vessel inside the placement box 5 and completing the fixation. This fixation method ensures that the pressure vessel remains stable throughout the heating and quenching process, ensuring heating uniformity and improving the stability of equipment operation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
