Description

Technical Field

[0001] This utility model relates to the field of furnace supports, specifically a furnace support and a high-temperature furnace. Background Technology

[0002] In high-temperature furnaces, such as electric ovens, furnace supports are typically placed at the bottom of the furnace cavity to support the workpieces placed inside. These workpieces are often heavy and need to be stacked. During high-temperature processing, the furnace supports are prone to deformation under the pressure of high temperatures and the workpieces, which can cause the workpieces to tip over and become damaged.

[0003] Therefore, how to address this deficiency in the existing furnace supports is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] Purpose of the utility model: The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a furnace support and a high-temperature furnace that can provide sufficient load-bearing capacity at high temperatures and is not easily deformed.

[0005] To achieve the above objectives, this application provides an in-furnace support, comprising a plurality of support bodies and a plurality of guide plates, wherein the top end faces of each guide plate are on the same plane, characterized in that the guide plates or support bodies are provided with a plurality of recesses, and the guide plates and support bodies are fitted together through the recesses; the top end face of each guide plate is higher than the top end face of the support body.

[0006] Furthermore, both the guide plate and the support body are provided with several notches, which makes the connection between the guide plate and the support body more secure and improves the structural stability of the furnace support.

[0007] Furthermore, the guide plates are parallel to each other, thus providing a more uniform load-bearing force for the workpiece.

[0008] Furthermore, each support is plate-shaped and parallel to the others, thus providing uniform support force to the guide plate.

[0009] Furthermore, the extension direction of the plate-shaped support is perpendicular to the extension direction of the guide plate, and the furnace support as a whole forms a mesh structure.

[0010] Furthermore, the bottom of the plate-shaped support has several depressions that can match the protrusions of the insulating bricks inside the high-temperature furnace.

[0011] Furthermore, all supports are of equal height, and the top surfaces of all guide plates are on the same horizontal plane, so as to make the overall structure of the furnace support more stable.

[0012] Furthermore, the guide plate and the support body are connected by notch welding to increase the overall integrity of the furnace support.

[0013] This application also provides a high-temperature furnace, which includes a furnace body, a door is provided on any side of the furnace body, and the inner cavity of the furnace body is provided with a furnace support as in any embodiment of this application.

[0014] Furthermore, the bottom surface of the furnace cavity is provided with heat-insulating bricks, and the heat-insulating bricks are provided with protrusions that fit into the bottom recess of the support body of the furnace support. The inner wall of the furnace is provided with heating wires, which are located in the inner wall area of ​​the furnace above the horizontal height of the top end face of the guide plate of the furnace support, thereby reducing the heat received by the furnace support.

[0015] This application has the following beneficial effects:

[0016] This application provides a furnace support, comprising several support bodies and several guide plates. The top surfaces of each guide plate are on the same plane. Each guide plate or support body has several recesses, which are fitted into the support bodies. This multiple recesses allow the furnace support to form a contact surface under forces acting in different directions when placing, picking up, or supporting workpieces, thereby improving the overall load-bearing capacity. Furthermore, the top surfaces of each guide plate are higher than the top surfaces of the support bodies, ensuring that the workpiece only contacts the guide plates, reducing the contact area between the workpiece and the furnace support. This reduces the heat transferred from the workpiece to the support body, making the furnace support less prone to deformation in high-temperature furnaces. Attached Figure Description

[0023] In the following description, reference is made to the accompanying drawings, which illustrate several embodiments of the present application. It should be understood that other embodiments may also be used, and changes in module or unit composition, electrical and operational aspects may be made without departing from the spirit and scope of this disclosure. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application.

[0024] The following combination Figures 1 to 5 This application is described in detail.

[0025] The furnace support and high-temperature furnace described in this application can be a dewaxing furnace, an electric baking furnace, or other types of furnaces used for heating workpieces.

[0026] As described in the background art, during high-temperature processing, the furnace support is prone to deformation under high temperature and workpiece pressure, which can lead to workpiece overturning and damage. This application provides a furnace support 10, including a guide plate 11 and a support body 12, in... Figure 1 In the illustrated embodiment, the furnace support 10 includes 5 guide plates 11 and 17 support bodies 12. The number of guide plates 11 and support bodies 12 is not limited in this application. The top end faces of each guide plate 11 are on the same plane. It should be understood that recesses may be provided only on each guide plate 11, only on each support body 12, or on both guide plates 11 and support bodies 12.

[0027] exist Figure 1 In the illustrated embodiment, the guide plate 11 is provided with a plurality of recesses 111, and the support body 12 is provided with recesses 121 that are adapted to the recesses 111. When the furnace support 10 is subjected to forces in different directions, the contact portions of the recesses 111 and 121 can form an abutment surface, thereby improving the stress stability of the furnace support 10 and thus improving the load-bearing capacity of the furnace support 10. It should be understood that, for ease of distinction, in this embodiment, the recesses 111 refer to the recesses on the guide plate 11, and the recesses 121 refer to the recesses on the support body 12.

[0028] like Figure 2 As shown, the top end face of the guide plate 11 of the furnace support 10 is higher than the top end face of the support body 12. That is, the horizontal height h1 of the top end face of the guide plate 11 is higher than the horizontal height h2 of the top end face of the support body 12. This allows the workpiece to only contact the guide plate, reducing the contact area between the workpiece and the furnace support, thereby reducing the heat transferred from the workpiece to the support body, making the furnace support less prone to deformation in the high-temperature furnace.

[0029] Furthermore, such as Figure 3As shown, the guide plates 11 are parallel to each other, thus providing a more uniform load-bearing force for the workpiece. In some other embodiments, there may also be a certain angle between the guide plates 11. The overall structural stability is higher when the guide plates 11 are parallel to each other. In one embodiment, the distance between two adjacent guide plates 11 is equal, wherein the distance between two adjacent guide plates 11 can be 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm or other distances, and this application does not limit this. In other embodiments, the distance between two adjacent guide plates 11 may also be unequal.

[0030] Furthermore, each support 12 is plate-shaped and parallel to each other. In one embodiment, the spacing between two adjacent supports 12 is equal, thereby providing relatively uniform support force to each guide plate 11 and further improving the overall load-bearing capacity of the furnace support 10. The spacing between two adjacent supports 12 can be 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, or other spacings; this application does not impose any limitations on this. In other embodiments, the spacing between two adjacent supports 12 may not be equal, and there may be a certain angle between multiple supports 12; this application does not impose any limitations on this.

[0031] Furthermore, the extending direction of the plate-shaped support 12 is perpendicular to the extending direction of the guide plate 11, forming a mesh structure, thereby increasing the placement area of ​​the workpiece. For details, please refer to [reference needed]. Figure 3 The top view of the furnace support 10 shown.

[0032] Furthermore, the bottom of the plate-shaped support 12 has several recesses that can match the protrusions of the heat-insulating bricks 22 inside the high-temperature furnace body 20 (see reference). Figure 5 This prevents the support 12 from moving left or right within the furnace body 20.

[0033] Furthermore, all supports 12 are of equal height, thus providing support at the same horizontal level for each guide plate 11. The top surfaces of each guide plate 11 are at the same horizontal plane, thereby providing a horizontal placement surface for the product.

[0034] Furthermore, the notch on the guide plate 11 and the slot on the support 12 are connected by welding, such as... Figure 4 As shown, the notch on the guide plate 11 and the slot on the support 12 are welded together to form a weld point 13. The welding makes the connection between the guide plate 11 and the support 12 more secure and increases the overall stability of the furnace support 10.

[0035] This application also provides a high-temperature furnace; please refer to [link / reference]. Figure 5The high-temperature furnace includes a furnace body 20, a door 21 is provided on any side of the furnace body 20, and the inner cavity of the furnace body 20 is provided with a furnace support 10 as in any embodiment of this application.

[0036] Furthermore, the bottom surface of the inner cavity of the furnace body 20 is provided with heat-insulating bricks 22. These heat-insulating bricks 22 have protrusions that fit into the recesses at the bottom of the support body 12, thus preventing the furnace support 10 from shifting laterally when placed on the heat-insulating bricks 22, further improving the stability of the furnace support 10. Heating wires are provided on the inner wall of the furnace body 20. These heating wires are located in the inner wall region of the furnace body 20 at a height higher than the top end face of the guide plate 11 of the furnace support 10, thereby reducing the heat exposure of the furnace support 10 and lowering the possibility of deformation.
