Description

Technical Field

[0001] This utility model relates to the field of air guide plate technology, specifically a hot air circulation air guide plate device. Background Technology

[0002] In the forging process, cooling chambers are widely used for cooling forgings. Existing cooling chamber structures include a main chamber body, variable frequency axial flow fans on both sides, a variable frequency exhaust fan at the top for heat exhaust, and guide vanes on the sides and top. When cooling is required, the variable frequency axial flow fans on both sides start operating. Airflow is guided by the guide vanes, flowing between the back of the guide vanes and the side walls of the cooling chamber to the bottom of the chamber, and then flowing upwards from the bottom of the workpiece, achieving effective heat exchange. Subsequently, the hot air, having absorbed heat, is extracted by the exhaust fan at the top, completing the entire cooling cycle. When installing the top guide vane and the two side guide vanes inside the cooling chamber, the two side guide vanes are bolted to the top guide vane, and then the hanger rods are passed through the cooling chamber and connected with nuts.

[0003] After a period of use, air deflectors require regular maintenance, such as cleaning the dust and impurities adhering to their outer walls. However, when removing air deflectors for cleaning, the relatively small space inside the cooling chamber and the fact that they are usually fixed with nuts make disassembly cumbersome and increase the difficulty of assembly and disassembly, thus affecting maintenance efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hot air circulation guide plate device, which makes the top guide plate and the two side guide plates easy to remove from the cooling chamber.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot air circulation guide plate device, comprising a top guide plate connected to the inner wall of a cooling chamber, side guide plates fixedly connected to both sides of the top guide plate, and multiple hangers connected to the top guide plate. The outer walls of the two side guide plates are slidably provided with sliding plates, and the outer walls of the side guide plates are provided with multiple sliding grooves. Multiple sliders fixedly connected to the sliding plates are slidably connected in the sliding grooves. Each hanger is connected to a connector on one side of the top outer wall of the cooling chamber.

[0006] Furthermore, the connector includes a rod, and a slot is provided at one end of the rod passing through the top of the cooling chamber, into which the rod is inserted.

[0007] Furthermore, a limiting rod is vertically inserted into the top surface of the insertion rod, with one end of the limiting rod passing through the insertion rod and inserted into the top wall of the cooling chamber.

[0008] Furthermore, a U-shaped top plate is fixedly connected to the top of the limiting rod, and L-shaped blocks are fixedly connected to the outer walls of both ends of the U-shaped top plate. A U-shaped pull plate is fixedly connected to the outer end of the insertion rod. Moving grooves are opened on the inner walls of the two vertical plates of the U-shaped pull plate, and the L-shaped blocks are slidably connected within the moving grooves.

[0009] Furthermore, an arc-shaped pull plate is fixedly connected to the top of the U-shaped top plate.

[0010] Furthermore, both sides of the insertion rod and the limiting rod at the insertion end are chamfered.

[0011] Furthermore, a U-shaped block is fixedly connected to the inner wall of the sliding plate, and a support rod is rotatably connected inside the U-shaped block, with the top of the support rod abutting against the bottom end of the side air guide plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model shortens the length of the original side air guide plate and sets a sliding plate, which allows the top air guide plate, side air guide plate and hanging rod to retract and descend vertically, so that the whole is located in the cooling chamber and can be pulled out as a whole. Compared with the conventional method of disassembling nuts one by one, it avoids the difficulty of disassembly in the small space of the cooling chamber, simplifies the disassembly operation and improves the replacement efficiency.

[0014] 2. With the cooperation of the plug rod and the slot, the disassembly of the lifting rod only requires pulling out the plug rod. Compared with the conventional nut connection limit, the position of the lifting rod is not only more stable and will not cause the lifting rod to fall due to the nut retraction, but also makes it easier to detach the lifting rod.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1 to 7 As shown, a hot air circulation guide plate device includes a top guide plate 2 connected to the inner wall of a cooling chamber 8, side guide plates 1 fixed (preferably bolted) to both sides of the top guide plate 2, and multiple hangers 3 connected to the top guide plate 2. Sliding plates 4 are slidably provided on the outer walls of the two side guide plates 1. Multiple sliding grooves 9 are provided on the outer walls of the side guide plates 1. Multiple sliders 7 fixedly connected to the sliding plates 4 are slidably connected in the sliding grooves 9. Each hanger 3 is connected to a connector on one side of the top outer wall of the cooling chamber 8.

[0025] like Figures 1 to 7 As shown, when the hot air circulation guide plate device of this utility model needs to be disassembled for cleaning and maintenance of the two side guide plates 1 and the top guide plate 2, the plug-in part on the outside of the hanging rod 3 can be removed, so that the U-shaped cover formed by the top guide plate 2 and the two side guide plates 1 can be directly lowered in the cooling chamber 8. When lowering, the sliding groove 9 on the outer wall of the side guide plate 1 slides on the outside of the slider 7 on the outer wall of the sliding plate 4. This setting allows the length of the side guide plate 1 to be retracted, so that after the top guide plate 2, the U-shaped cover formed by the two side guide plates 1 and the hanging rod 3 are lowered, they can be located in the cooling chamber 8. There is no need to disassemble the hanging rod 3 and the top guide plate 2 one by one. The whole thing can be pulled down and pulled out of the cooling chamber 8, avoiding the difficulty of disassembly due to the small space of the cooling chamber 8.

[0026] It should be noted that a sealing gasket can be provided between the contact surfaces of the sliding plate 4 and the side guide plate 1. The sealing gasket can be fixedly installed on the outer wall of the sliding plate 4 or the side guide plate 1. The sealing gasket is mainly used to prevent air leakage or air escaping between the interactive plate 4 and the side guide plate 1, that is, to make up for the gaps that may exist in the slide structure and ensure efficient airflow guidance.

[0027] In addition, the sealing gasket should be made of high-temperature resistant material, such as ceramic fiber liner or improved encapsulated gasket, to ensure long-term stability and sealing effect.

[0028] like Figure 4 and Figure 5 As shown, the connector includes a plug rod 6, and the hanging rod 3 passes through the top of the cooling chamber 8 and has a slot 17 at one end, into which the plug rod 6 is inserted.

[0029] Specifically, in order to facilitate the disassembly of the boom 3 from the cooling chamber 8, the insert rod 6 can be pulled to disengage the insert rod 6 from the slot 17 of the boom 3. Compared with the conventional nut connection limit, the position of the boom 3 is not only more stable and will not cause the boom 3 to fall due to the nut retraction, but also makes it easier to disengage the boom 3.

[0030] like Figure 4 and Figure 5 As shown, a limiting rod 13 is vertically inserted into the top surface of the insertion rod 6, and one end of the limiting rod 13 passes through the insertion rod 6 and is inserted into the top wall of the cooling chamber 8.

[0031] Specifically, to prevent the insertion rod 6 from detaching due to vibration during equipment use, the limiting rod 13 can be inserted into the insertion rod 6. This setting makes the position of the insertion rod 6 more stable, thereby ensuring that the lifting rod 3 is more stable.

[0032] like Figure 5 As shown, a U-shaped top plate 14 is fixedly connected to the top of the limiting rod 13, and L-shaped blocks 16 are fixedly connected to the outer walls of both ends of the U-shaped top plate 14. A U-shaped pull plate 11 is fixedly connected to the outer end of the insertion rod 6. Moving grooves 12 are opened on the inner walls of the two vertical plates of the U-shaped pull plate 11, and the L-shaped blocks 16 are slidably connected in the moving grooves 12.

[0033] Specifically, when the limiting rod 13 is inserted, it will cause the L-shaped blocks 16 on both sides of the U-shaped top plate 14 to slide in the moving groove 12 in the U-shaped pull plate 11. This setting allows the limiting rod 13 to be connected with the insertion rod 6, preventing the limiting rod 13 from being lost.

[0034] It should be noted that the insertion rod 6 is T-shaped. After the insertion rod 6 is inserted into the slot 17, you only need to push the insertion rod 6 with force. That is, it performs the insertion function horizontally and the limiting and abutting function vertically. After the insertion rod 6 is pushed to the bottom, the limiting rod 13 can be smoothly inserted into the cooling chamber 8.

[0035] like Figure 5 As shown, an arc-shaped pull plate 15 is fixedly connected to the top of the U-shaped top plate 14. The arc-shaped pull plate 15 facilitates the pulling of the U-shaped top plate 14.

[0036] like Figure 5 As shown, both sides of the insertion rod 6 and the limiting rod 13 are chamfered at the insertion end. The chamfering facilitates smooth insertion of the insertion rod 6 and the limiting rod 13.

[0037] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, a U-shaped block 10 is fixedly connected to the inner wall of the sliding plate 4, and a support rod 5 is rotatably connected inside the U-shaped block 10. The top of the support rod 5 abuts against the bottom of the side air guide plate 1.

[0038] Specifically, in order to prevent the sliding plate 4 from easily sliding on the outer wall of the side guide plate 1, the support rod 5 can be rotated so that it rotates within the U-shaped block 10 and the top surface of the support rod 5 abuts against the bottom surface of the side guide plate 1. This ensures that the sliding plate 4 will not slide or rise on the bottom surface of the side guide plate 1.

[0039] Although the present invention 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 invention should be included within the protection scope of the present invention.
