Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for flanges, and specifically to a heat treatment device for forged steel flanges. Background Technology

[0002] Forged steel flanges are components widely used in pipe connections, mechanical equipment, and other fields. They are usually heat-treated during the manufacturing process to improve their mechanical properties and durability.

[0003] Traditional heat treatment processes for forged steel flanges typically include the following steps: First, the heating chamber door is opened, and the base plate is removed from the heating chamber. Then, workers use hoisting equipment to lift the forged steel flange to be treated onto the base plate, and start the trolley under the base plate to retract the base plate into the heating chamber. The chamber door is closed, and the heating elements are activated to heat the forged steel flange. After heating is complete, the base plate is removed from the heating chamber by the trolley, and then the heated forged steel flange is transported to a water tank for cooling using hoisting equipment.

[0004] However, the aforementioned traditional heat treatment process for forged steel flanges has the following drawbacks:

[0005] 1. During the loading and unloading process of the heating box, the opening of the silo door and the removal of the forged steel flange after heating will cause the temperature inside the factory to rise sharply, affecting the normal working environment of the staff. At the same time, the hot air rushing in may burn the skin and eyes of the staff, posing a certain safety hazard.

[0006] 2. When the chamber door is opened, the high-temperature gas inside the heating chamber comes into contact with the low-temperature gas inside the factory, causing heat loss and lowering the temperature inside the heating chamber, resulting in energy waste. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Example 1

[0036] To address the technical problems in the background section, the following heat treatment apparatus for forged steel flanges is provided:

[0037] Combination Figures 1-10 As shown, the heat treatment device for forged steel flanges provided by this utility model includes a base plate 1; a cooling tank 2 is fixedly connected to the top surface of the base plate 1, an isolation box 3 is fixedly connected to the top surface of the cooling tank 2, an auxiliary material handling component 4 is installed inside the isolation box 3, a material handling component 5 is installed on one side of the isolation box 3, an exhaust hood 6 is fixedly connected to the top surface of the inner cavity of the isolation box 3, and a heating device 7 is installed on the top surface of the base plate 1 and on one side of the isolation box 3; the heating device 7 includes a heating box 71, the heating box 71 is fixedly connected to the top surface of the base plate 1, and the heating box 7... Heating tubes 72 are fixedly connected to the four sides of the inner cavity of the heating box 71. A storage rack 73 is fixedly connected to the bottom surface of the inner cavity of the heating box 71. A mesh plate 74 is placed on the top surface of the storage rack 73. An airflow assembly 75 is installed on the top surface of the outer surface of the heating box 71. A lifting hydraulic rod 76 is fixedly connected to one end of the top surface of the heating box 71. A heat preservation door 77 is fixedly connected to the output end of the lifting hydraulic rod 76. An airflow chamber 78 is provided inside the heating box 71. Air inlets 79 are provided at equal intervals on the bottom surface of the inner cavity of the heating box 71. The air inlets 79 are connected to the airflow chamber 78.

[0038] Through the cooperation of the heating box 71, heating tube 72, heat preservation door 77, lifting hydraulic rod 76, storage rack 73 and mesh plate 74 in the heating device 7, the subsequent heating treatment of the flange can be realized.

[0039] The airflow within the heating chamber 71 is ensured through the inlet hole 79 and the airflow cavity 78, allowing the high-temperature air to better heat treat the flange.

[0040] In this embodiment, the airflow assembly 75 includes a blower 751, a square box 752, and a connecting pipe 753. The blower 751 and the square box 752 are fixedly connected to the top surface of the heating box 71. The connecting pipe 753 is fixedly connected to the top surface of the heating box 71. The square box 752 is fixedly connected to the surface of the connecting pipe 753. One end of the connecting pipe 753 is fixedly connected to the isolation box 3. Heat dissipation fins 754 are fixedly connected to the surface of the connecting pipe 753 and located inside the square box 752. The surface of the square box 752 is connected to the airflow cavity 78 through the air duct 755. The output end of the blower 751 is connected to the inside of the square box 752 through the air inlet pipe 756.

[0041] By using the connecting pipe 753 in the airflow assembly 75, the hot air discharged from the heating box 71 can be injected into the isolation box 3 for storage, thus avoiding the large amount of heat loss inside the heating box 71 during subsequent loading and unloading, which would cause the workshop temperature to be high and make it inconvenient for workers to work. At the same time, the temperature of the heating box 71 would be low, resulting in the waste of resources.

[0042] The air injected can be heated by the heat dissipation fins 754 on the surface of the connecting pipe 753. This results in a large temperature difference in the heating box 71 after the heated air enters the heating box 71, which affects the heat treatment process of the flange.

[0043] Example 2

[0044] like Figures 1-10 As shown, based on the above embodiments, this embodiment further provides the following:

A connecting groove 49 is provided on one side of the connecting block 48.

[0046] The lifting hydraulic rod 42 in the auxiliary material handling component 4 drives the horizontal rail 43 to rise and fall, thereby driving the translation rod 46 and the insert plate 47 to move downward, so as to facilitate the delivery of the heated flange to the cooling pool 2 for quenching treatment. At the same time, under the action of the isolation box 3, the discharge of water vapor and flue gas generated at high temperature is reduced.

[0047] Example 3

[0048] like Figures 1-10 As shown, based on the above embodiments, this embodiment further provides the following:

[0049] The material handling assembly 5 includes a mobile trolley 51, a sealing door plate 52 fixedly connected to one side of the mobile trolley 51, and track clearance grooves 53 respectively provided on both sides of the sealing door plate 52. A material handling component 54 is installed on one side of the sealing door plate 52. The material handling component 54 includes a reciprocating track 541 and a reciprocating motor 542. The reciprocating track 541 is fixedly connected to one side of the sealing door plate 52. A reciprocating threaded rod 543 is rotatably connected inside the reciprocating track 541. A reciprocating rod 544 is threadedly connected to the surface of the reciprocating threaded rod 543. A connecting post 545 is fixedly connected to the bottom surface of the reciprocating rod 544. One end of the connecting post 545 is inserted into the connecting groove 49. The reciprocating motor 542 is fixedly connected to the other side of the sealing door plate 52. The output end of the reciprocating motor 542 is fixedly connected to the reciprocating threaded rod 543.

[0050] The isolation box 3 can be sealed by the sealing door panel 52, preventing the injected hot air from flowing out of the isolation box 3;

[0051] The reciprocating motor 542, reciprocating threaded rod 543, reciprocating track 541, reciprocating rod 544 and connecting column 545 work together to drive the translation rod 46 and the insert plate 47 to move, thereby facilitating the subsequent picking up and putting down of the mesh plate 74, so as to realize material picking and unloading.

[0052] Working principle and usage process of this utility model:

[0053] In use:

[0054] In use, first, connect the exhaust hood 6 to the external equipment. After connection, the operator hoists the forged steel flange requiring heat treatment to the top of the mesh plate 74. Then, start the moving trolley 51, which moves the sealing door 52 along the external track. When the sealing door 52 moves, it moves the material-picking component 54 as a whole. At this time, the material-picking component 54 is connected to the translation rod 46. Therefore, when the material-picking component 54 moves, it moves the translation rod 46 along the external track. At the same time, it also moves the insert plate 47, the mesh plate 74 on the insert plate 47, and the forged steel flange as a whole into the isolation box 3. It also moves the translation rod 46 from the external track into the track groove 44. When the sealing door 52 seals the isolation box 3, the moving trolley 51 stops working. At the same time, the lifting hydraulic rod 76 is started. When the lifting hydraulic rod 76 works, it moves the insulation door 77 up, thereby raising the heating box 7. 1. When the heating box is opened, the reciprocating motor 542 drives the reciprocating threaded rod 543 to rotate, thereby moving the reciprocating rod 544 and the connecting column 545. When the reciprocating rod 544 moves, it will drive the horizontal rod 46 to slide along the track groove 44. The movement of the translation rod 46 will drive the insert plate 47, the mesh plate 74 on the insert plate 47, and the forged steel flange to move into the heating box 71. When the mesh plate 74 moves into the heating box 71 and is above the storage rack 73, the lifting hydraulic rod 42 drives the horizontal track 43 and the translation rod 46 to move downward. The downward movement of the translation rod 46 will drive the insert plate 47 to move downward. At this time, the insert plate 47 can place the mesh plate 74 with the forged steel flange on the storage rack 73. Then, the reciprocating threaded rod 543 drives the translation rod 46 and the insert plate 47 to exit from the heating box 71. The lifting hydraulic rod 76 will drive the heat preservation door 77 to descend and seal it, so that the forged steel flange can be calcined inside.

[0055] During calcination, the heating tube 72 is activated, which heats the heating chamber 71. During the heating process, some of the heat also enters the isolation chamber 3 through the connecting pipe 753. At this time, the isolation chamber 3 is sealed, which raises the temperature inside the isolation chamber 3. At the same time, the high temperature generated by the connecting pipe 753 begins to heat the gas in the square box 752, thus heating the air injected by the blower 751. The heated air enters the airflow chamber 78 and is discharged into the heating chamber 71 through the air inlet 79, allowing the internal air to circulate and enabling better heat treatment of the forged steel flange.

[0056] After calcination is complete, the insulation door 77 opens. Simultaneously, the material handling component 54 moves the insert plate 47 and the translation rod 46 into the heating chamber 71, removing the mesh plate 74 and the forged steel flange. After removal, the insulation door 77 is closed, and the lifting hydraulic rod 42 is activated. The lifting hydraulic rod 42 moves the horizontal track 43, the translation rod 46, the insert plate 47, the mesh plate 74, and the forged steel flange downwards as a whole, immersing the mesh plate 47 and the forged steel flange in the cooling pool 2. The water in the cooling pool 2 cools them down. When the insert plate 47... 7. When moving downwards, the insert plate 47 will detach from the material picking component 54. During cooling, the gas generated inside will be treated and discharged by external equipment in conjunction with the exhaust hood 6. After cooling, the mesh plate 74 will be lifted and then transported to the outside by the mobile trolley 51 for easy lifting later. Since the entire operation is carried out inside the heating box 71 and the isolation box 3, the high temperature inside the heating box 71 is prevented from flowing into the workshop, which would cause a large loss of air from the heating box 71 and increase the temperature in the workshop, making it inconvenient for the staff to work.
