Description

Technical Field

[0001] This application belongs to the field of baking oven technology, specifically relating to an offline baking oven for intermediate packaging. Background Technology

[0002] The offline nozzle baking furnace plays a crucial role in steel continuous casting production. Its main function is to ensure that the nozzle reaches the appropriate temperature before casting, thus avoiding problems such as steel freezing and casting failure due to insufficient temperature at the start of casting. Currently, offline nozzle baking furnaces generally use an open baking method, which cannot guarantee the baking effect of the nozzle. Since the nozzle is a key component in the intermediate casting process, the quality of nozzle baking significantly affects the performance. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides an offline baking oven for medium-sized bread.

[0004] The technical solution adopted to achieve the purpose of this application is an offline baking oven for medium-sized bread, comprising:

[0005] The furnace body has a chamber for placing the water inlet. The furnace body includes interconnected furnace walls, furnace top, and furnace bottom. A notch is opened on one side of the furnace wall. The inner diameter of the notch is larger than the outer diameter of the water inlet. A fire port and a chimney opening are provided on the furnace wall opposite to the notch. The chimney opening is located above the fire port. The furnace top has an opening for holding the water inlet.

[0006] A chimney is installed at the chimney opening and communicates with the chamber;

[0007] A furnace cover, located on the top of the furnace, is used to cover the opening and the water inlet;

[0008] The furnace door is hinged to the furnace wall and is used to cover the opening.

[0009] In some embodiments, the furnace cover is box-shaped, with one end of the furnace cover hinged to the furnace top, and the hinge point between the furnace cover and the furnace top is on the side away from the notch.

[0010] In some embodiments, the furnace wall, the furnace top, the furnace bottom, and / or the furnace door are provided with a frame and an insulation layer from the outside to the inside;

[0011] The frame has several layers of support skeletons for holding the insulation layer.

[0012] In some embodiments, an insulation layer that cooperates with the furnace cover is also provided around the opening of the furnace top.

[0013] In some embodiments, at least one side of the furnace wall is provided with reinforcing ribs, and there are at least two reinforcing ribs, one of which extends from one side of the top of the furnace wall toward the other side near the bottom of the furnace; the other reinforcing rib extends from the other side of the top of the furnace wall toward the other side near the bottom of the furnace, and the two reinforcing ribs are arranged alternately to form an X shape.

[0014] In some embodiments, the furnace door is provided with a frame and an insulation layer from the outside to the inside, and the furnace door is hinged to the side wall of the furnace wall by a hinge assembly, which is located on the outside of the furnace door and the furnace wall.

[0015] In some embodiments, the hinge assembly includes a hinge plate and a hinge shaft fixedly connected to the hinge plate. The hinge shaft is Z-shaped, with one end hinged to the furnace door and the other end hinged to the furnace wall.

Detailed Implementation

[0025] To enable those skilled in the art to better understand this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an offline baking oven 100 for medium-duty baking includes an oven body 110, a chimney 120, an oven cover 130, and an oven door 140. The oven body 110 has a chamber for placing a sprue 200. The oven body 110 includes an oven wall 111, an oven top 112, and an oven bottom 113 connected to each other. A notch 1111 is opened on one side of the oven wall 111. The inner diameter of the notch 1111 is larger than the outer diameter of the sprue 200. The side opposite to the notch 1111... The furnace wall 111 is provided with a fire opening 1112 and a chimney opening 1113, with the chimney opening 1113 located above the fire opening 1112; the furnace top 112 is provided with an opening for holding a water inlet 200; the chimney 120 is installed at the chimney opening 1113 and communicates with the chamber; the furnace cover 130 is provided at the furnace top 112 and is used to cover the opening and the water inlet 200; the furnace door 140 is hinged to the furnace wall 111 and is used to cover the opening 1111.

[0027] The baking oven includes a furnace body 110, a chimney 120, a furnace cover 130, and a furnace door 140. Both the furnace cover 130 and the furnace door 140 enclose the furnace body 110, improving sealing and heat insulation. Compared to baking ovens without a furnace cover 130 and a furnace door 140, this design offers better sealing, thereby improving baking efficiency to some extent.

[0028] The furnace body 110 includes a furnace wall 111, a furnace top 112, and a furnace bottom 113 connected to each other. A notch 1111 is provided on one side of the furnace wall 111. The inner diameter of the notch 1111 is larger than the outer diameter of the water inlet 200, that is, the top of the water inlet 200 can be placed at the opening of the furnace top 112. The water inlet 200 and the notch 1111 are separated. The flame introduced from the fire port 1112 can enter through the gap between the water inlet 200 and the notch 1111, thereby baking the outer diameter of the water inlet 200. Compared with baking through the inner diameter of the water inlet 200, baking through the outer diameter of the water inlet 200 results in a larger contact area between the flame and the water inlet 200, and the water inlet 200 heats up faster, thus improving the baking efficiency.

[0029] The furnace wall 111 on the opposite side of the opening 1111 is provided with a fire port 1112 and a chimney opening 1113. The chimney opening 1113 is located above the fire port 1112, that is, the flame is introduced from the fire port 1112. Since the furnace body 110, chimney 120, furnace cover 130 and furnace door 140 form a relatively closed baking oven, the baking efficiency is improved. The flue gas generated during the baking process can be discharged through the chimney opening 1113 to maintain the cleanliness and safety of the baking oven environment.

[0030] The furnace cover 130 is located on the furnace top 112 and is used to cover the opening and the water inlet 200; the furnace door 140 is hinged to the furnace wall 111 and is used to cover the notch 1111. That is, after the water inlet 200 is placed, the overall sealing of the baking oven can be improved by closing the furnace cover 130 and the furnace door 140; when it is necessary to remove the water inlet 200, the furnace cover 130 and the furnace door 140 can be opened to expose the water inlet 200, making it easy to remove the water inlet 200.

[0031] Therefore, this solution improves the sealing performance and heat preservation effect by setting a furnace cover 130 and a furnace door 140 on the furnace body 110. Both the furnace cover 130 and the furnace door 140 wrap the furnace body 110. In addition, the inner diameter of the notch 1111 is larger than the outer diameter of the water inlet 200. That is, the gap between the water inlet 200 and the notch 1111 is set so that the flame introduced from the fire port 1112 can enter through the gap between the water inlet 200 and the notch 1111, thereby baking the outer diameter of the water inlet 200. The contact area between the flame and the water inlet 200 is larger, and the water inlet 200 heats up faster, thus improving the baking efficiency.

[0032] like Figure 3As shown, in some embodiments, the furnace lid 130 is box-shaped, with one end hinged to the furnace top 112. The furnace lid 130 can be connected to the furnace top 112 using a hinge to achieve an opening or closing function. Closing the furnace lid 130 during the baking process at the sprue 200 serves to insulate and maintain heat. In other embodiments, the hinge point between the furnace lid 130 and the furnace top 112 is located away from the notch 1111. Since the sprue 200 needs to be placed on the side of the notch 1111, to avoid interference between the hinge point and other components, and to ensure sufficient installation space at the hinge point between the furnace lid 130 and the furnace top 112, the hinge point is installed on the side away from the notch 1111. In some embodiments, after the furnace cover 130 covers the water inlet 200 and the opening, the furnace cover 130 extends out of the furnace top 112. While ensuring that the furnace cover 130 can cover the water inlet 200, the furnace cover 130 will not interfere with the water inlet 200.

[0033] In some embodiments, the furnace cover 130 is provided with a handle for easy opening or closing. Since the furnace cover 130 is box-shaped, the handle can be welded to the end of the furnace cover 130.

[0034] like Figure 3 As shown, in some embodiments, the furnace wall 111, furnace top 112, furnace bottom 113, and / or furnace door 140 are sequentially provided with a frame 150 and an insulation layer 151 from the outside to the inside; the frame 150 is provided with several layers of supporting skeletons 152 for holding the insulation layer 151. The frame 150 is welded from steel plates, and the skeletons can be arranged at an angle to the frame 150 within the frame 150. The frame 150 is a supporting component of the supporting skeleton 152 of the baking oven. The insulation layer 151 can be made of zirconium fiber. The frame 150 and the supporting skeletons 152 enclose several insulation areas, and the insulation layer 151 is placed in the insulation areas. The insulation layer 151 is fixed to the inside of the frame 150 and plays a role in heat insulation during the baking process at the sprue 200. The support frame 152 can be made of an alloy with high strength and good heat resistance. The support frame 152 plays the role of skeletal support, enhances the support force of the frame 150 on the insulation layer 151, maintains the shape of the insulation layer 151, and avoids deformation of the insulation layer 151 due to high temperature, which would affect the overall insulation performance.

[0035] like Figure 3 As shown, in some embodiments, an insulation layer 151 that cooperates with the furnace cover 130 is also provided around the opening of the furnace top 112. That is, when the furnace cover 130 covers the opening, an insulation layer 151 is also provided around the opening of the furnace top 112. The insulation layer 151 provided between the furnace cover 130 and the outer periphery of the opening of the furnace top 112 improves the sealing performance between the furnace cover 130 and the opening to a certain extent, thereby further improving the overall insulation performance.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, at least one side of the furnace wall 111 is provided with reinforcing ribs 1114, and there are at least two reinforcing ribs 1114. One reinforcing rib 1114 extends from one side of the top of the furnace wall 111 towards the other side near the furnace bottom 113; the other reinforcing rib 1114 extends from the other side of the top of the furnace wall 111 towards the other side near the furnace bottom 113, and the two reinforcing ribs 1114 are staggered to form an X shape. Since the temperature inside the furnace body 110 cavity is high during the baking process, the insulation layer 151 may deform due to the high temperature. Providing reinforcing ribs 1114 on the furnace wall 111 can serve as a support to prevent the furnace body 110 from deforming as a whole.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the furnace door 140 is provided with a frame 150 and an insulation layer 151 from the outside to the inside. The furnace door 140 is hinged to the side wall of the furnace wall 111 by a hinge assembly 160, which is located on the outside of the furnace door 140 and the furnace wall 111. The furnace door 140 includes the frame 150 and insulation. The furnace door 140 is relatively thick. In order to further improve the heat insulation effect and ensure that the furnace door 140 has a large opening angle, the hinge assembly 160 is located on the outside of the furnace door 140 and the furnace wall 111. That is, during the opening or closing of the furnace door 140, the hinge assembly 160 will not affect the opening or closing of the furnace door 140.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments, the hinge assembly 160 includes a hinge plate 161 and a hinge shaft 162 fixedly connected to the hinge plate 161. The hinge shaft 162 is Z-shaped, with one end hinged to the furnace door 140 and the other end hinged to the furnace wall 111. This ensures that when the furnace door 140 is closed, the side walls of the furnace door 140 and the furnace wall 111 can fit together. When the furnace door 140 is closed, part of the hinge plate 161 fits against the furnace door 140 and part of it fits against the furnace wall 111. The length of the hinge shaft 162 is longer than the width of the hinge plate 161, ensuring that one end of the hinge shaft 162 is hinged to the furnace door 140 and the other end is hinged to the furnace wall 111. In some embodiments, the hinge plate 161 is located at the center of the furnace door 140, and there are two hinge shafts 162, one of which is located above the hinge plate 161 and connected to the hinge plate 161, and the other hinge shaft 162 is located below the hinge plate 161 and connected to the hinge plate 161, so as to ensure the stability of the opening of the furnace door 140.

[0039] like Figure 4As shown, in some embodiments, the burner 1112 is rectangular in shape, and its lowest point is located above the lowest point of the chamber. This allows a flame to be introduced through the center of the burner 1112. The flame introduced through the burner 1112 can enter through the gap between the nozzle 200 and the notch 1111, thus heating the outer diameter of the nozzle 200. The larger contact area between the flame and the nozzle 200 results in faster heating of the nozzle 200, improving heating efficiency. Since the lowest point of the burner 1112 is located above the lowest point of the chamber, while ensuring the flame is fed from the burner 1112 into the notch 1111, the size of the burner 1112 is relatively small, thereby improving sealing and providing good heat retention for the immersion nozzle 200.

[0040] like Figure 4 As shown, in some embodiments, the chamber and opening of the furnace body 110 are coaxially arranged. The baking holes of the baking oven are smaller, improving the sealing performance, and the immersion-type water inlet 200 has a good heat preservation effect.

[0041] like Figure 1 As shown, in some embodiments, the baking oven further includes a temperature probe 170 and a temperature display 180. The temperature probe 170 extends into the cavity and is electrically connected to the temperature display 180. The temperature probe 170 is a sensor used to measure the internal temperature of the baking oven. The temperature probe 170 can acquire the temperature of the oven cavity 110, thereby achieving the purpose of collecting the temperature of the oven cavity 110. Then, the controller converts it into the actual temperature inside the oven for display, making it convenient to view the actual temperature of the oven cavity 110.

[0042] Through the above embodiments, this application has the following beneficial effects or advantages:

[0043] 1) The baking oven of this application includes a furnace body 110, a chimney 120, a furnace cover 130, and a furnace door 140. That is, both the furnace cover 130 and the furnace door 140 cover the furnace body 110, which improves the sealing performance and heat preservation effect. Compared with baking ovens without a furnace cover 130 and a furnace door 140, this solution has better sealing performance, thereby improving the baking efficiency to a certain extent.

[0044] 2) The inner diameter of the notch 1111 in this application is larger than the outer diameter of the nozzle 200, that is, the top of the nozzle 200 can be placed at the opening of the furnace top 112. The nozzle 200 and the notch 1111 are separated, and the flame introduced from the fire port 1112 can enter through the gap between the nozzle 200 and the notch 1111, thereby baking the outer diameter of the nozzle 200. Compared with the previous baking through the inner diameter of the nozzle 200, baking through the outer diameter of the nozzle 200 results in a larger contact area between the flame and the nozzle 200, and the nozzle 200 heats up faster, thus improving the baking efficiency.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0046] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
