Description

Technical Field

[0001] This utility model relates to the technical field of inlet structure of annealing furnaces, and specifically to an inlet structure of an annealing furnace. Background Technology

[0002] Annealing furnaces are energy-saving, periodic furnaces mainly used for annealing metallic materials. The annealing process involves heating the metal to a certain temperature and holding it at that temperature for a period of time, then cooling it at a suitable rate (usually natural cooling or controlled cooling) to soften the metal, enhance its ductility, improve its mechanical properties, or repair internal damage.

[0003] Existing annealing furnaces typically have an inlet consisting of a furnace door and a feeding conveyor mechanism. However, the conveyor mechanism is generally quite long, making it impossible to completely close the furnace door. Therefore, an inlet structure for annealing furnaces is proposed, which facilitates the loading and unloading of materials and allows for complete closure of the furnace door, thereby improving processing convenience. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides an inlet structure for an annealing furnace. The loading and unloading structure facilitates material feeding and discharge, and also allows for complete closure of the furnace door, thereby improving processing convenience.

[0005] The technical solution adopted by this utility model to solve its technical problem is an inlet structure of an annealing furnace, including an annealing furnace body, slide rail A, slide rail B and support frame. A carrying rack is provided on the inner side of the annealing furnace body corresponding to slide rail A, and a support frame is provided on one side of the annealing furnace body and the carrying rack.

[0006] A furnace door is provided on the inner side of the support frame between the slide rails B. A hydraulic cylinder is installed at the center of the top of the support frame by bolts. An exhaust vent is opened at the center of the surface of the furnace door. An exhaust fan is installed on one side of the support frame by bolts.

[0007] By adopting the above technical solution, the slide rail A is used in conjunction with the load rack and the brake rollers at the bottom of the base to slide into and out of the annealing furnace body, which facilitates loading and unloading of materials and makes operation convenient. The support frame supports the hydraulic cylinder and the furnace door, and the hydraulic cylinder drives the furnace door to rise and fall with the help of the slide rail B. When the load rack is inside the annealing furnace body, the furnace door can be completely closed, thereby improving the convenience of processing.

[0008] After processing, the sealing plate can be moved by hand by handle B, and the hot air can be exhausted through the exhaust vent by the exhaust fan to achieve a pre-cooling effect. When no cooling is needed, the sealing plate can be closed to block the exhaust vent, making the operation convenient.

[0009] Specifically, slide rails A are provided on both sides of the bottom of the inner wall of the annealing furnace body through reserved grooves, and the load rack is slidably connected to slide rails A through sliders on both sides.

[0010] By adopting the above technical solution, the slide rail A, in conjunction with the carrying frame, slides into and out of the annealing furnace body under the action of brakeable rollers at the bottom of the base, so as to facilitate the loading and unloading of materials by personnel.

[0011] Specifically, the bottom of the rack is provided with a base, the bottom of the base is provided with brakeable rollers, and a handle A is installed at the center of the bottom of the base by bolts.

[0012] By adopting the above technical solution, handle A is made easier for people to grip.

[0013] Specifically, slide rails B are provided on both sides of the inner wall of the support frame through reserved grooves, the furnace door is slidably connected to the slide rails B through sliders on both sides, and the hydraulic cylinder drive end is connected to the furnace door.

[0014] By adopting the above technical solution, the furnace door is raised and lowered by a hydraulic cylinder in conjunction with slide rail B.

[0015] Specifically, a support frame is provided on one side of the furnace door corresponding to the outer perimeter of the exhaust vent. A sealing plate is passed through a reserved opening on one side of the support frame. A handle B is provided on one side of the sealing plate. The exhaust fan's suction end corresponds to the exhaust vent.

[0016] By adopting the above technical solution, the sealing plate and exhaust fan are supported by a support frame.

[0017] The beneficial effects of this utility model are:

[0018] The inlet structure of the annealing furnace described in this utility model allows the furnace to slide in and out of the furnace body via a slide rail A in conjunction with a carrying rack and braked rollers at the bottom of the base. This facilitates loading and unloading of materials and makes operation convenient. The furnace door is supported by a support frame, and the furnace door is raised and lowered by the support frame in conjunction with the slide rail B. The furnace door can be completely closed when the carrying rack is inside the furnace body, thereby improving processing convenience.

[0019] The inlet structure of the annealing furnace described in this utility model allows the sealing plate to be moved by hand after processing, and the hot air to be exhausted through the exhaust vent by the exhaust fan, thus achieving a pre-heating effect. When heat dissipation is not required, the sealing plate can be closed to block the exhaust vent, making the operation convenient. Attached Figure Description

[0027] A furnace door 10 is provided on the inner side of the support frame 7 between the slide rails B8. A hydraulic cylinder 9 is installed at the center of the top of the support frame 7 by bolts. An exhaust vent 11 is opened at the center of the surface of the furnace door 10. An exhaust fan 15 is installed on one side of the support frame 12 by bolts.

[0028] In use, the slide rail A2, in conjunction with the load rack 3 and the brake rollers 5 at the bottom of the base 4, slides into and out of the annealing furnace body 1, facilitating loading and unloading of materials and making operation convenient. The support frame 7 supports the hydraulic cylinder 9 and the furnace door 10. The hydraulic cylinder 9 drives the furnace door 10 to rise and fall with the help of the slide rail B8. When the load rack 3 is inside the annealing furnace body 1, the furnace door 10 can be completely closed, thereby improving processing convenience.

[0029] After processing, the sealing plate 13 can be pulled out by the handle B14, and the hot air can be exhausted through the exhaust fan 15 and the exhaust port 11 to achieve a pre-heating effect. When heat dissipation is not required, the sealing plate 13 can be closed to block the exhaust port 11, which is convenient to operate.

[0035] During use, the furnace door 10 is raised and lowered by the hydraulic cylinder 9 in conjunction with the slide rail B8.

[0036] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes a support frame 12 provided on one side of the furnace door 10 corresponding to the outer periphery of the exhaust port 11, a sealing plate 13 penetrating through a reserved opening on one side surface of the support frame 12, a handle B14 provided on one side of the sealing plate 13, and the exhaust fan 15 exhaust end corresponding to the exhaust port 11.

The support frame 7 supports the oil cylinder 9 and the furnace door 10. The oil cylinder 9 drives the furnace door 10 to rise and fall with the cooperation of the slide rail B8.
