DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] In the present invention, the terms "bottom", "inside", "middle", "vertical", "horizontal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific position, or to be constructed and operated in a specific position.

[0050] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0051] In addition, the terms "disposed", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0052] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0053] In the related art, there is often a certain degree of alignment deviation between the furnace door and the pipe opening of the furnace tube, which may cause the furnace door to be difficult to keep vertical during use. When the furnace door is opened or closed, it may collide with the pipe opening of the furnace tube.

[0054] The inventors have found that Figure 1 and Figure 2As shown, a heating device includes a furnace door mechanism and a furnace tube 500. The furnace door mechanism includes a first furnace door 100, a second furnace door 200 and a bracket 300. The second furnace door 200 is supported on the first furnace door 100 through the bracket 300. The first furnace door 100 is used to connect with an external power mechanism to drive the second furnace door 200 to move to the position of the pipe mouth 510 of the furnace tube 500 to close the pipe mouth 510. In order to make the second furnace door 200 tightly against the pipe mouth 510 of the furnace tube 500 to maintain a seal, the component used to support the second furnace door 200 on the bracket 300 is a plurality of elastic support components 320. The plurality of elastic support components 320 provide horizontal thrust to make the second furnace door 200 abut against the pipe mouth 510. The horizontal direction is as shown in FIG. Figure 2 The X0-X1 direction in .

[0055] The first furnace door 100 is kept vertical during use. To ensure that the second furnace door 200 is vertical, the distance between the end of the multiple elastic support components 320 away from the first furnace door 100 and the first furnace door 100 must be kept consistent. In this way, the second furnace door 200 supported on the first furnace door 100 by the multiple elastic support components 320 is parallel to the first furnace door 100, and the second furnace door 200 can be kept vertical. However, in order to support multiple positions of the second furnace door 200, the multiple elastic support components 320 are distributed at multiple different positions in the vertical direction. Figure 2 In the Y0-Y1 direction, part of the elastic support assembly 320 is located at the top, part of the elastic support assembly 320 is located in the middle, and part of the elastic support assembly 320 is located at the bottom. The reason why the second furnace door 200 cannot remain vertical is that the forces acting on the second furnace door 200 at multiple different positions of the elastic support assembly 320 are different, resulting in different deformation amounts of the elastic support assembly 320. For example, the elastic support assembly 320 at the bottom has a horizontal length of L1 after deformation, and the elastic support assembly 320 at the top has a horizontal length of L2 after deformation, and L2>L1, which causes the second furnace door 200 to be unable to remain vertical. After the second furnace door 200 is closed at the pipe mouth 510, the top of the second furnace door 200 is closer to the pipe mouth 510 than its bottom, and the bottom of the second furnace door 200 cannot be close to the pipe mouth 510, resulting in an increase in the leakage rate. When the second furnace door 200 is closed, it is easy to collide with the pipe mouth 510 of the furnace tube 500, causing the pipe mouth 510 of the furnace tube 500 to be damaged.

[0056] Based on the above analysis, the present application provides a furnace door mechanism, which adds a gasket, which is arranged between the bracket body and the mounting surface. The gasket is configured to make the second furnace door vertical by eliminating the difference in deformation, thereby avoiding the furnace door mechanism from colliding with the furnace tube when closing, avoiding the second furnace door from being damaged, and also improving the sealing between the furnace door mechanism and the furnace tube, reducing the leakage rate, thereby improving the preparation quality and output of solar cells.

[0057] The technical solution of the utility model will be described below in conjunction with embodiments and drawings.

[0058] The first aspect, refer to Figure 3 and Figure 4 An embodiment of the present application provides a furnace door mechanism, including a first furnace door 100 , a second furnace door 200 , a bracket 300 and a gasket 400 .

[0059] The first furnace door 100 is arranged vertically. Figure 4 Optionally, the first furnace door 100 is a metal furnace door. The metal furnace door has high strength and can better support the second furnace door 200.

[0060] The second furnace door 200 is arranged opposite to the first furnace door 100, and the first furnace door 100 has a mounting surface 110 on one side facing the second furnace door 200. Optionally, the second furnace door 200 is a quartz furnace door. The quartz furnace door has a good heat insulation effect and can isolate the heat in the furnace tube from being conducted to the external environment.

[0061] The support 300 is located between the second furnace door 200 and the first furnace door 100. Optionally, the support 300 is a metal support, such as a steel support or an aluminum alloy support. The metal support can bear a large weight and will not soften at a high temperature, thereby maintaining a supporting effect.

[0062] The bracket 300 includes a bracket body 310 and a plurality of elastic support components 320 disposed on the bracket body 310. The number of the elastic support components 320 may be two or more, for example, five, six, seven or eight. The bracket body 310 is fixedly connected to the mounting surface 110, one end of the elastic support component 320 is connected to the bracket body 310, and the other end of the elastic support component 320 is connected to the second furnace door 200.

[0063] The gasket 400 is disposed between the bracket body 310 and the mounting surface 110 . The gasket 400 is configured to offset the deformation difference of the second furnace door 200 relative to the first furnace door 100 , so that the second furnace door 200 is vertically disposed. The deformation difference is obtained by elastic deformation of the plurality of elastic support components 320 .

[0064] As described above, the deformation difference is the difference between the plurality of elastic support components 320 and the plurality of elastic support components 320. Figure 4 The different positions in the Y0-Y1 direction in the present application lead to the length difference in the X0-X1 direction after the elastic deformation. The present application offsets the deformation difference by adding a gasket 400, thereby preventing the furnace door mechanism from colliding with the furnace tube 500 when closing, preventing the second furnace door 200 from being damaged, and improving the sealing between the furnace door mechanism and the furnace tube 500, thereby reducing the leakage rate, thereby improving the preparation quality and output of solar cells.

[0065] As an optional embodiment, in this application, reference is made to Figure 3 The support body 310 is a circular plate, and a plurality of elastic support components 320 are circumferentially distributed on the edge of the circular plate. Since the pipe opening of the furnace pipe in the related art is circular, the second furnace door 200 for closing the pipe opening is also circular, and the plurality of elastic support components 320 distributed circumferentially are conducive to better supporting the circular second furnace door 200. Preferably, the plurality of elastic support components 320 and the circular plate are integrally formed.

[0066] As an optional implementation, refer to Figure 4 In the present application, the elastic support assembly 320 includes an elastic support member 321, and the elastic support member 321 includes an extension portion 3212 extending from the support body 310 toward the direction close to the second furnace door 200, and a support portion 3211 formed by bending outward from the end of the extension portion 3212. The term "direction close to the second furnace door 200" can be the X0-X1 direction, or a direction that is at an angle to the X0-X1 direction, but the above angle cannot be a right angle. The term "outward bending" in the term "outward bending" refers to the direction from the midpoint of the support body 310 in the Y0-Y1 direction to its two ends.

[0067] The support portion 3211 is connected to the second furnace door 200. The support portion 3211 is arranged opposite to the mounting surface 110 with a gap G therebetween. The gap G provides space for the support portion 3211 to elastically deform relative to the mounting surface 110. Thus, the support portion 3211 can elastically deform relative to the mounting surface 110 and move closer to or away from the mounting surface 110, so that the width of the gap G changes.

[0068] Specifically, there are various distances between the multiple support parts 3211 and the bottom end of the second furnace door 200, so that the vertically arranged second furnace door 200 exerts various forces on the multiple support parts 3211, and the various forces include various force values ​​and various force directions. In the case where the gasket 400 is not provided, the various forces cause the multiple support parts 3211 to have various deformation amounts to form deformation amount differences. The support parts 3211 subjected to different forces have different degrees of elastic deformation and thus have different distances from the installation surface 110.

[0069] After adding the gasket 400, the distance between each support portion 3211 and the installation surface 110 can be kept consistent, that is, the width of each interval G is consistent. Since the second furnace door 200 is connected to the above-mentioned multiple support portions 3211, the second furnace door 200 is parallel to the first furnace door 100 and the second furnace door 200 is vertical.

[0070] As an optional embodiment, in this application, reference is made to Figure 4The elastic support assembly 320 further includes a spring 325 disposed in the interval G, and two ends of the spring 325 respectively abut against the support portion 3211 and the mounting surface 110. The spring 325 is used to enhance the elastic support of the support portion 3211, thereby making the elastic force of the support portion 3211 greater.

[0071] As an optional embodiment, in this application, reference is made to Figure 4 The extension portion 3212 is connected to the edge of the circular plate and extends along the axial direction of the circular plate away from the first furnace door 100. Figure 4 The support portion 3211 is connected to the end of the extension portion 3212 away from the first furnace door 100 and extends in the radial direction of the circular plate away from the circular plate. Figure 4 In the Y0-Y1 direction, the elastic support member 321 is configured in this way to be L-shaped, so that the support portion 3211 has better elasticity and it is convenient to set the spring 325 between the support portion 3211 and the mounting surface 110.

[0072] As an optional embodiment, in this application, reference is made to Figure 4 The elastic support assembly 320 further includes a guide member 326. A guide hole 323 is provided on the support portion 3211. The guide member 326 extends in a direction close to the first furnace door 100 and sequentially passes through the guide hole 323 and the spring 325 to be fixedly connected to the first furnace door 100. The guide member 326 is used to guide the support portion 3211 to deform in a preset direction. In one embodiment, the guide member 326 guides the support portion 3211 to deform in a horizontal direction. The horizontal direction is as follows: Figure 4 The X0-X1 direction in .

[0073] As an optional embodiment, in this application, reference is made to Figure 4 One of the support part 3211 and the second furnace door 200 is provided with a block 322 and the other is provided with a slot 210. The block 322 is clamped in the slot 210 to enable the support part 3211 and the second furnace door 200 to be clamped, which facilitates the assembly of the support part 3211 and the second furnace door 200, and then supports the second furnace door 200 on the bracket 300.

[0074] As an optional embodiment, in the present application, a plurality of snap-fit ​​protrusions 240 are provided on the second furnace door 200, the snap-fit ​​protrusions 240 are separated from the second furnace door 200, and a plurality of snap-fit ​​grooves 210 are formed between the plurality of snap-fit ​​protrusions 240 and the second furnace door 200. The snap block 322 is provided on the support portion 3211.

[0075] As an optional embodiment, in this application, reference is made to Figures 4 to 6A circular side wall 220 is provided on the side of the second furnace door 200 facing the elastic support assembly 320, and the circular side wall 220 can circumferentially seal the pipe opening of the furnace pipe. The inner side of the side wall 220 is surrounded by a mounting groove 230, and a plurality of clamping protrusions 240 are arranged on the inner side of the side wall 220 at intervals along the circumference of the side wall 220, and a notch 250 is formed between two adjacent clamping protrusions 240.

[0076] Furthermore, the support portion 3211 is embedded in the installation groove 230 through the notch 250, and the second furnace door 200 is configured to rotate relative to the support portion 3211 in the installation groove 230 and have a snap-fit ​​position, and the snap-fitting groove 210 on the second furnace door 200 at the snap-fitting position snaps into the snap-fitting block 322 on the support portion 3211.

[0077] It can be seen that the second furnace door 200 is connected to the bracket 300 by first inserting the support part 3211 through the notch 250 and then rotating the second furnace door 200 until the clamping slot 210 clamps the clamping block 322. The above assembly method has the advantages of fewer assembly steps and lower assembly difficulty.

[0078] As an optional embodiment, in this application, reference is made to Figure 5 The end of the support part 3211 away from the circular plate has an enlarged portion 3213 with an enlarged width. The enlarged portion 3213 is used to increase the surface area of ​​the support part 3211 so that the support part 3211 has better load-bearing performance.

[0079] As an optional embodiment, in this application, reference is made to Figure 4 , the gasket 400 is arranged between the bottom of the bracket body 310 and the mounting surface 110. The selection of the setting position of the gasket 400 is analyzed as follows: in the vertical direction, the second furnace door 200 causes the elastic support component 320 at the bottom to be subjected to greater compression deformation. In the case where the gasket 400 is not arranged, the distance between the end of the elastic support component 320 at the bottom away from the first furnace door 100 and the mounting surface 110 is shorter. In other words, the gasket 400 is added to the bottom of the bracket body 310, so that the distance between the end of the elastic support component 320 at the bottom away from the first furnace door 100 and the mounting surface 110 is increased, thereby making the distance between the end of each elastic support component 320 away from the first furnace door 100 and the mounting surface 110 consistent, thereby making the second furnace door 200 vertical.

[0080] As an optional embodiment, in this application, reference is made to Figure 7The gasket 400 is provided with a plurality of symmetrical first fixing holes 410, and the bottom of the bracket body 310 is provided with a plurality of second fixing holes 311 corresponding to the positions of the plurality of first fixing holes 410, so that the gasket 400 is better fixed between the bracket body 310 and the mounting surface 110, and the displacement of the gasket 400 is prevented and the deformation difference cannot be eliminated. Furthermore, by passing a fixing member, such as a screw, through the first fixing hole 410 and the second fixing hole 311 corresponding to the first fixing hole 410 and screwing it to the first furnace door 100, the gasket 400, the circular plate and the first furnace door 100 are fixedly assembled.

[0081] As an optional embodiment, in this application, reference is made to Figure 7 In the related art, the elastic support assembly 320 at the same horizontal position has no deformation difference, while the gasket 400 is an axisymmetric shape with the vertical line as the symmetry axis, which is conducive to the gasket 400 to keep the second furnace door 200 vertical.

[0082] As an optional embodiment, in this application, reference is made to Figure 4 and Figure 7 The bottom edge of the gasket 400 overlaps with the bottom edge of the bracket body 310, so that the bottom side of the bracket body 310 can be sufficiently supported.

[0083] Optionally, the gasket 400 is a metal gasket. The metal gasket can withstand high temperatures, and its size does not change much under the influence of temperature, and can be applied to the high temperature working conditions of the furnace door mechanism of the present application.

[0084] Optionally, the thickness of the gasket 400 is 0.5 mm to 3.5 mm, including any value within the thickness range, such as 0.5 mm, 2 mm or 3.5 mm, to match the difference in deformation amount in the related art.

[0085] The second aspect, such as Figure 8 As shown, an embodiment of the present application provides a heating device, comprising a furnace tube 500 and a furnace door mechanism as described in the first aspect. The furnace tube 500 has a pipe opening 510. The furnace door mechanism is used to open and close the pipe opening 510. When the furnace door mechanism is in a closed state, the axis of the furnace tube 500 and the axis of the second furnace door 200 are at the same horizontal position to ensure that the second furnace door 200 seals the pipe opening 510 of the furnace tube 500.

[0086] Optionally, the furnace tube 500 is a cylindrical tube body, and the second furnace door 200 is a cylindrical furnace door, so that the two can be better matched.
