Description

Technical Field

[0001] This utility model belongs to the field of hydrogen storage material preparation technology, and specifically relates to a furnace door structure for a hydrogen storage material heating furnace. Background Technology

[0002] In the field of hydrogen storage material preparation, heating furnaces play a crucial role. The preparation of hydrogen storage materials typically involves a series of complex physical and chemical processes, with heating being one of the key steps. First, various raw materials, which may include metals, alloys, or other compounds, are precisely mixed in specific proportions. After mixing, they are placed in a heating furnace. Inside the furnace, the materials react at high temperatures to form materials with hydrogen storage properties.

[0003] Currently, most hydrogen production and storage material heating furnaces on the market have inadequate furnace door connection structures. Commonly, hinges or other simple connectors are used to connect the furnace door and the furnace body. For example, Chinese patent CN221463859U discloses an installation structure for a combustion furnace door, where the door is directly hinged to the furnace body. Because the heating furnace generates high temperatures during operation, the hinges are exposed to these high temperatures for extended periods, causing changes in the mechanical properties of the material. This leads to a decrease in the hinge's strength and toughness, thus affecting the connection stability of the furnace door. Furthermore, frequent opening and closing of the furnace door subjectes the hinge to repeated mechanical stress, easily causing wear and loosening, further reducing the stability of the furnace door. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a furnace door structure for a hydrogen production and storage material heating furnace.

[0005] This utility model provides a furnace door structure for a hydrogen production and storage material heating furnace, including a furnace door frame and a furnace door body disposed inside the furnace door frame. A door hinge is provided on one side of the furnace door body, and the door hinge is connected to the furnace door body through a U-shaped reinforcing plate. Support seats are respectively provided at the bottom and top of the door hinge, and the support seats are fixedly connected to the discharge port of the hydrogen production and storage material heating furnace. The door hinge is rotatably connected to the support seats. A limit component is provided on the support seat located at the bottom of the door hinge to fix the opening and closing angle of the furnace door body.

[0006] A further embodiment is that the U-shaped reinforcing plate includes two reinforcing arms symmetrically arranged on the door hinge. The reinforcing arms are L-shaped, with one end of the reinforcing arm fixedly connected to the door hinge and the other end of the reinforcing arm provided with a connecting lug. A hinge seat is provided on the furnace door body, and the connecting lug is hinged to the hinge seat.

[0007] A further embodiment is that the limiting component includes a limiting shaft seat, the bottom of which is fixedly connected to the support seat, and the bottom of the door hinge is inserted into the limiting shaft seat and rotatably connected to it.

[0008] A first limiting plate is provided on the side of the limiting shaft seat away from the furnace door body, and the first limiting plate has a plurality of limiting holes; a second limiting plate is provided on the door shaft, and the second limiting plate has positioning holes; the first limiting plate and the second limiting plate are connected by a pin.

[0009] A further embodiment is that the first limiting plate is an arc-shaped plate, and the arc-shaped plate is concentrically arranged with the limiting shaft seat;

[0010] Three limiting holes are spaced apart on the first limiting plate, and the central angles of two adjacent limiting holes are equal.

[0011] A further option is that the furnace door body is curved.

[0012] A further embodiment is that the furnace door body is provided with an observation window and a camera window.

[0013] A further embodiment is that a handle is provided on the side of the furnace door frame away from the door hinge, and a door lock is also provided at the bottom of the furnace door frame on the side of the handle to fix the position of the furnace door body after it is closed.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The door hinge of this utility model is fixed to the outlet of the heating furnace through a support base and is rotatably connected to the support base, so that the furnace door body can rotate flexibly around the door hinge to realize manual opening and closing, which simplifies the operation process and reduces the labor intensity of manual opening and closing. The furnace door body and the door hinge are connected by a U-shaped reinforcing plate to enhance the overall strength of the furnace door and the stability of the furnace door opening and closing process.

[0016] The U-shaped reinforcing plate of this invention consists of symmetrically arranged L-shaped reinforcing arms that are hinged to the hinge seat of the furnace door body via connecting ears, forming a stable triangular support structure. This effectively enhances the connection strength between the door hinge and the furnace door body, preventing structural deformation caused by prolonged high temperatures or frequent opening and closing, and extending the service life of the furnace door.

[0017] The first limiting plate on the limiting shaft seat of this utility model is an arc-shaped plate, concentrically arranged with the limiting shaft seat, and has multiple limiting holes with equal central angles distributed at intervals. The second limiting plate on the door shaft is connected to the first limiting plate by a pin. Different limiting holes can be selected to fix the opening and closing angle of the furnace door according to actual needs (such as material discharge, maintenance, and ventilation). For example, when fully open, the pin is inserted into the farthest limiting hole, and when partially open, the middle hole is selected, which not only meets diverse operational needs but also prevents safety hazards caused by excessive rotation of the furnace door.

[0018] The furnace door body adopts an arc-shaped design, which fits better with the arc-shaped structure of the heating furnace outlet. When locked with a door lock, it can significantly reduce the gaps in the sealing surface, improve the sealing performance of the vacuum or inert gas environment inside the furnace, prevent the entry of outside air or leakage of gases such as hydrogen, and ensure the stability of the composition of hydrogen storage materials during high-temperature processing.

[0024] To make the objectives, technical solutions, design methods, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0025] like Figure 1 As shown, this utility model provides a furnace door structure for a hydrogen production and storage material heating furnace, including: a furnace door frame 1 and a furnace door body 2 disposed inside the furnace door frame 1. In order to make the furnace door body 2 fit the arc-shaped structure of the heating furnace outlet better, the furnace door body 2 in this embodiment has an arc surface structure. A door hinge 4 is provided on one side of the furnace door body 2. The door hinge 4 is connected to the furnace door body 2 through a U-shaped reinforcing plate. Support seats 3 are respectively provided at the bottom and top of the door hinge 4. The support seats 3 are fixedly connected to the outlet of the hydrogen production and storage material heating furnace. The door hinge 4 is rotatably connected to the support seats 3. When the furnace door structure is opened or closed, the door hinge 4 rotates along the support seats 3. A limit component is provided on the support seat 3 at the bottom of the door hinge 4 to fix the opening and closing angle of the furnace door body 2.

[0026] Continue to refer to Figure 1The aforementioned U-shaped reinforcing plate includes two reinforcing arms 5 symmetrically arranged on the door hinge 4. Each reinforcing arm 5 has an L-shaped structure, with one end welded to the door hinge 4 and the other end equipped with a connecting lug 7. A hinge seat 6 is provided on the furnace door body 2, and the connecting lug 7 is hinged to the hinge seat 6. Each reinforcing arm 5 forms a stable triangular support structure, effectively enhancing the connection strength between the door hinge 4 and the furnace door body 2, preventing structural deformation caused by prolonged high temperatures or frequent opening and closing, and extending the service life of the furnace door.

[0027] like Figure 2 and Figure 3 As shown, the limiting assembly includes a limiting shaft seat 8, the bottom of which is fixedly connected to the support seat 3.

A second limiting plate 10 is provided on the door shaft 4, and a positioning hole is provided on the second limiting plate 10. The first limiting plate 9 and the second limiting plate 10 are connected by a pin 14. Specifically, the first limiting plate 9 is an arc-shaped plate, which is concentrically arranged with the limiting shaft seat 8. Three limiting holes 13 are spaced apart on the first limiting plate 9, with the central angles of adjacent limiting holes 13 being equal. In this embodiment, the central angle of adjacent limiting holes 13 is 30°. Different limiting holes can be selected to fix the opening angle of the furnace door according to actual needs. For example, when maintenance is required, the furnace door is opened to 90°. At this time, the positioning hole and the farthest limiting hole 13 are aligned, and the pin 14 is inserted into the positioning hole and the limiting hole 13. When material discharge is required, the furnace door is opened to 60°. At this time, the positioning hole and the middle limiting hole 13 are aligned, and the pin 14 is inserted into the positioning hole and the limiting hole 13.
