Description

Technical Field

[0001] The utility model relates to the technical field of air guiding devices, and particularly relates to an air guiding device for heat treatment processing. Background Art

[0002] An industrial furnace is a heat treatment device that uses the heat generated by fuel combustion or electric energy conversion to heat materials or workpieces in industrial production. Heat treatment refers to a metal hot working process in which metal materials, in a solid state, change the chemical composition and structure on the surface or inside of the material through heating, heat preservation, and cooling means to obtain the required properties. However, during the process of heat treating metals using an industrial furnace, in order to ensure the uniformity of the furnace temperature inside the furnace, usually, a blower is first used to drive the hot air inside the furnace to flow to form hot air, and then the hot air is guided by a wind deflector, and the furnace temperature is increased in the form of hot air circulation to heat the workpiece.

[0003] In the prior art, the publication number CN219390542U discloses an air guiding device for an industrial furnace, which includes: a first wind deflector and two second wind deflectors. The first wind deflector is arranged between the two second wind deflectors, and the two ends of the first wind deflector respectively extend to the back of the two second wind deflectors. At the upper and lower ends of the back of the second wind deflector, first sliding grooves are provided, and a limiting plate is slidably installed inside the first sliding grooves. A threaded rod is arranged on the end face of the limiting plate, and the threaded rod penetrates through the second wind deflector and the first wind deflector and extends to the back of the first wind deflector.

[0004] When it is in use, the length of the wind deflector can be adjusted, but the position of the wind deflector is fixed, which easily causes the uneven distribution of the temperature inside the furnace during the heat treatment process, so that the workpieces inside the furnace are heated unevenly everywhere, and further affects the quality of the workpieces inside the furnace. Therefore, it is necessary to design an air guiding device for heat treatment processing to solve the above problems.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0032] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the present utility model provides an air guiding device for heat treatment processing, including:

[0033] A housing 1, on which an air guiding mechanism is provided. It should be noted that air guiding treatment is carried out through the air guiding mechanism, and the front side of the housing 1 is connected to the furnace body;

[0034] The air guiding mechanism includes a main air guiding component and an auxiliary air guiding component;

[0035] The main air guiding component includes an air guiding box 2, an air guiding nozzle 3, a power motor 4, and a power shaft 5. The power motor 4 is fixedly installed on the side of the housing 1, the output end of the power motor 4 is fixedly connected to the power shaft 5, the end of the power shaft 5 is fixedly connected to the air guiding box 2, and the air guiding nozzle 3 is fixedly installed on the front side of the air guiding box 2;

[0036] It should be noted that when the power motor 4 is started, the power motor 4 drives the power shaft 5 to rotate back and forth, the power shaft 5 drives the air guiding box 2 to swing back and forth, and the air guiding box 2 drives the air guiding nozzle 3 to swing back and forth. In this way, the hot air in the air guiding box 2 can be evenly discharged into the furnace body from the air guiding nozzle 3, so that the temperature distribution inside the furnace body is uniform, and the quality of the workpieces in the furnace body after heat treatment is ensured;

[0037] The auxiliary air guiding component includes a hot air inlet pipe 6, a high-temperature resistant hose 8, a main pipe 9, an air guiding head 10, and an auxiliary unit. The hot air inlet pipe 6 is fixedly installed on the housing 1, and both ends of the high-temperature resistant hose 8 are respectively connected to the hot air inlet pipe 6 and the main pipe 9, and the air guiding head 10 is installed on the main pipe 9.

[0038] Through the above-mentioned guiding air component, the external hot air flows successively in the hot air inlet pipe 6, the high-temperature resistant hose 8 and the main pipe 9, and finally enters the air guiding box 2 through the air guiding head 10.

[0039] Specifically, the auxiliary unit includes a rectangular block 11, a connecting block 12, a counterweight 13, a branch block 14, a collar 15 and a cam 16. The bottom of the rectangular block 11 is fixedly connected to the hot air inlet pipe 6. The two side surfaces of the connecting block 12 are respectively fixedly connected to the counterweight 13 and the main pipe 9. The side surface of the branch block 14 is fixedly connected to the counterweight 13. It should be noted that the counterweight 13 has a certain weight. When the cam 16 rotates, it can lift the branch block 14, and due to the weight of the counterweight 13 and its connecting components, the components such as the counterweight 13 and the branch block 14 can return to their original positions.

[0040] The counterweight 13 is vertically slidably sleeved on the outside of the rectangular block 11. The collar 15 is fixedly installed on the side wall of the air guiding box 2. The cam 16 is fixedly sleeved on the outside of the collar 15, and the cam 16 is in contact with the branch block 14.

[0041] It should be noted that the power shaft 5, the collar 15 and the hot air inlet pipe 6 are on the same horizontal axis.

[0042] Through the above structure, when the air guiding box 2 rotates, the air guiding box 2 can drive the collar 15 to rotate. The collar 15 drives the cam 16 to rotate. The cam 16 will push the branch block 14, so that the branch block 14, the counterweight 13, the connecting block 12, the main pipe 9 and the air guiding head 10 can move upward synchronously. When the air guiding box 2 rotates in the reverse direction, the collar 15 drives the cam 16 to rotate in the reverse direction. At this time, the weight of the counterweight 13 and its connecting components moves downward, so that the air guiding head 10 can move vertically back and forth, evenly introducing the external hot air into the air guiding box 2, which is convenient for the hot air in the air guiding box 2 to be evenly discharged into the furnace body from the air guiding nozzle 3 subsequently, making the temperature distribution in the furnace body uniform and ensuring the quality of the workpieces in the furnace body after heat treatment.

[0043] Working principle:

[0044] S1: The external hot air flows successively in the hot air inlet pipe 6, the high-temperature resistant hose 8 and the main pipe 9, and finally enters the air guide box 2 through the air guide head 10. Start the power motor 4, and the power motor 4 drives the power shaft 5 to rotate back and forth. The power shaft 5 drives the air guide box 2 to swing back and forth. When the air guide box 2 rotates, the air guide box 2 can drive the collar 15 to rotate. The collar 15 drives the cam 16 to rotate. The cam 16 will push the branch block 14. In this way, the branch block 14, the counterweight 13, the connecting block 12, the main pipe 9 and the air guide head 10 can move upward synchronously. When the air guide box 2 rotates in the reverse direction, at this time, due to the self-weight of the counterweight 13 and its connecting components, it will move downward. In this way, the air guide head 10 can move vertically back and forth, evenly introducing the external hot air into the air guide box 2, which is convenient for the hot air in the air guide box 2 to be evenly discharged into the furnace body from the air guide nozzles 3 subsequently, making the temperature distribution in the furnace body uniform and ensuring the quality of the workpieces in the furnace body after heat treatment;

[0045] S2: When the air guide box 2 swings back and forth, it will drive the air guide nozzles 3 to swing back and forth. In this way, the hot air in the air guide box 2 can be evenly discharged into the furnace body from the air guide nozzles 3, making the temperature distribution in the furnace body uniform and ensuring the quality of the workpieces in the furnace body after heat treatment.

[0046] Specifically, an adaptor round hole 7 is formed on the side of the air guide box 2, and the hot air inlet pipe 6 is in contact with the inner wall of the adaptor round hole 7. The end of the hot air inlet pipe 6 penetrates through the collar 15. It should be noted that this will not affect the rotation of the collar 15.

[0047] Specifically, a limit disc 17 is fixedly sleeved on the outside of the hot air inlet pipe 6, and the end of the limit disc 17 is in contact with the air guide box 2. It should be noted that the stability of the air guide box 2 during rotation can be improved.

[0048] Specifically, the air guide nozzles 3 are communicated with the inside of the air guide box 2, and the high-temperature resistant hose 8 and the air guide head 10 are both communicated with the inside of the main pipe 9. It should be noted that it is convenient for the external hot air to flow through the high-temperature resistant hose 8, the main pipe 9 and the air guide head 10, and can be blown out from the air guide nozzles 3 on the air guide box 2.

[0049] Specifically, the branch block 14 is located above the collar 15. It should be noted that the positions of the branch block 14 and the collar 15 are limited.

[0050] The above has introduced in detail a wind guiding device for heat treatment processing provided by the present utility model. Specific embodiments are applied in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
