Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature roasting containers, in particular to a roasting bracket with a long service life. Background Art

[0002] Most high-temperature roasted products require high-temperature saggers as containers for the products. However, as high-temperature sintering fixtures, saggers have many defects. First of all, due to the design and actual service life of sagger products, general products are relatively thick and heavy, with high energy consumption during use. Due to the multi-sided integration, they are affected by thermal expansion and contraction during use, and have a short service life. They are scrapped after a few times or dozens of times, and the cost of use is high. Due to the thick wall of the sagger, it also affects the sintering of the product itself. In order to fully burn the product, the high-temperature insulation time can only be extended. In addition to increasing energy consumption, it also affects the uniform sintering of the product. For the sintering of electronic products, in addition to requiring uniform high-temperature sintering, there are also high requirements for the surface temperature of the product during the cooling process. The sagger is thick and has high heat storage, which has a great impact on the consistency of cooling. In order to ensure the consistency of the product, the number of loaded products is often reduced during production, which further increases the production cost. Utility Model Content

[0040] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0041] Please refer to Figures 1 to 8 The utility model relates to a baking bracket with a long service life, comprising a bottom plate 1, a first side plate 2, a second side plate 3, a column 4, a first crossbeam 5 and a second crossbeam 6;

[0042] The bottom plate 1 is in a square shape, and grooves 11 are respectively provided at the four corners of the bottom plate 1;

[0043] The cross section of the column 4 matches the groove 11;

[0044] The four sides of the column 4 are respectively provided with linear grooves 43 extending along the Z direction of the column 4;

[0045] The column 4 is provided with a first through hole 41 in the X direction, and a plurality of first through holes 41 are distributed in an array along the Z direction of the column 4; the column 4 is provided with a second through hole 42 in the Y direction, and a plurality of second through holes 42 are distributed in an array along the Z direction of the column 4;

[0046] In the assembled state, the two ends of the first crossbeam 5 are respectively detachably plugged into the first through holes 41 of the column 4, and the two ends of the second crossbeam 6 are respectively detachably plugged into the second through holes 42 of the column 4;

[0047] The Y-direction and the Y-direction reverse sides of the bottom plate 1 are respectively mounted on the first crossbeam 5;

[0048] The X-direction and the X-direction reverse sides of the bottom plate 1 are respectively mounted on the second crossbeam 6;

[0049] The lower part of the first side plate 2 abuts against the upper part of the Y-direction or Y-opposite side of the bottom plate 1, and the two sides of the first side plate 2 are respectively located in the linear groove 43 on one side of the column 4;

[0050] The lower portion of the second side plate 3 abuts against the upper portion of the X-direction or X-opposite side of the bottom plate 1 , and both sides of the second side plate 3 are respectively located in the linear groove 43 on one side of the column 4 .

[0051] Reference Figures 1 to 4 , as a first implementation, the height of the first through hole 41 in the same layer is higher than the height of the second through hole 42;

[0052] In the above embodiment, the plugging of the first crossbeam 5 and the second crossbeam 6 can be independent of each other, which further improves the convenience of assembly.

[0053] or refer to Figures 5 to 8As a second embodiment, the bottom heights of the first through hole 41 and the second through hole 42 in the same layer are the same, and the Z-direction inner wall spacing of the first through hole 41 is greater than the Z-direction inner wall spacing of the second through hole 42. In this structure, there are two ways to connect the first crossbeam 5 and the second crossbeam 6. The first way is to first insert the first crossbeam 5 into the second through hole 42, and then insert the second crossbeam 6 into the first through hole 41, so that the second crossbeam 6 is mounted on the top of the first crossbeam 5; the second way is that the first crossbeam 5 is shorter, and after the first crossbeam 5 is inserted into the second through hole 42, the two ends of the second crossbeam 6 do not interfere with the first through hole 41, and then the second crossbeam 6 is inserted into the first through hole 41, so that the first crossbeam 5 and the second crossbeam 6 are at the same height.

[0054] In the above implementation manner, the original sagger structure is changed into a plate-type assembly structure, and the column 4, the first beam 5 and the second beam 6 are used to form a bracket for assembly. In this way, the thickness of each plate can be optimized according to the actual high-temperature load-bearing requirements, thereby saving energy consumption. This assembly structure reduces the cracking of the sagger due to thermal expansion and contraction, greatly increases the service life, saves production costs, and at the same time reduces the thickness and weight, reduces the heat storage effect, and significantly improves the performance of the fired products.

[0055] The use of columns 4 and crossbeams to replace the original supporting function of the sagger provides more flexible space assembly and more space volume options for the product. For example, straight grooves 43 are set on the four sides of the column 4, and the first through hole 41 and the second through hole 42 are both through structures. The side plates can be connected by the straight grooves 43 on the four sides of the column 4, and the space of the container can be expanded in an array manner; since the column 4 and the side plates are connected by straight grooves 43, the crossbeam is passed through the first through hole 41 or the second through hole 42, and assembly is easier.

[0056] In the above embodiments, the column 4 serves as the load-bearing part of the bracket, and the cross-sectional shape can be square, circular or other different geometric shapes. Figure 1 system Figure 8 As a preferred embodiment, the cross-section of the column 4 is square; the width of the linear groove 43 is greater than 15-25% of the thickness of the first side plate 2 and the second side plate 3, so as to facilitate assembly and prevent the first side plate 2 or the second side plate 3 from being deformed; the size of the first through hole 41 of the column 4 is 30-40% greater than the size of the beam; the first beam 5 and the second beam 6 are respectively used to penetrate the first through hole 41 and the second through hole 42 of the column 4, so as to support the bottom plate 1. The first side plate 2 and the second side plate 3 are pressed against the bottom plate 1 at the bottom, and the side edges are limited in the linear groove 43 of the column 4 to form a wall, which plays an isolation role and prevents the baked products from contacting with the open flame.

[0057] In the above embodiments, when assembling, first position the column 4, first set up the first beam 5 and the second beam 6 of a layer, then set up the bottom plate 1 on the beam, make the grooves 11 at the four corners of the bottom plate 1 abut against the column 4, then connect the first side plate 2 and the second side plate 3, complete the assembly of one layer, put the product to be baked in the layer, and then build the next layer structure in the above order. Since the first through hole 41 and the second through hole 42 are both through holes, the first beam 5 or the second beam 6 can be inserted and positioned from the outside during assembly, which further improves the convenience of assembly.

[0058] As a preferred embodiment, a convex strip 62 is provided in the upper middle section of the second cross beam 6 , the height of the convex strip 62 is equal to the thickness of the first cross beam 5 in the Z direction, and the length of the convex strip 62 in the Y direction is equal to the edge length of the bottom plate 1 in the X direction.

[0059] In the above embodiment, since the first through hole 41 and the second through hole 42 are staggered in distribution up and down, the first cross beam 5 and the second cross beam 6 have a height difference, and a convex strip 62 is provided through the upper middle section of the second cross beam 6, and the height of the convex strip 62 is equal to the Z-axis thickness of the first cross beam 5, and the Y-axis length of the convex strip 62 is equal to the X-axis edge length of the bottom plate 1, so that the bottom plate 1 can be simultaneously against the upper part of the first cross beam 5 and the second cross beam 6 during assembly, thereby improving the structural stability, and when the roasting material is placed on the bottom plate 1, the sealing of the bracket is improved to prevent the external open flame from directly contacting the internal roasting material.

[0060] As a preferred embodiment, the material of the bottom plate 1, the first side plate 2, the second side plate 3, the column 4, the first cross beam 5 and the second cross beam 6 is silicon nitride; or a refractory material suitable for the special material requirements of the baked products; the surface of the bottom plate 1, the first side plate 2, the second side plate 3, the column 4, the first cross beam 5 and the second cross beam 6 is provided with an alumina coating, or a refractory coating suitable for the special material requirements of the baked products.

[0061] In the above embodiments, in the above embodiments, in the selection of materials, in the utility model, the material of the bottom plate 1, the first side plate 2, the second side plate 3, the column 4, the first crossbeam 5 and the second crossbeam 6 is preferably silicon nitride, which takes advantage of the fact that silicon nitride is more resistant to high temperatures than alumina, has a smaller thermal expansion coefficient and higher high-temperature strength, so that the roasting container has a longer service life. Therefore, the product can be made thinner and lighter than a conventional sagger, which is more conducive to product sintering and saves energy.

[0062] As a preferred embodiment, the longitudinal cross-section of the first through hole 41 is polygonal or circular; the shape of the end of the first crossbeam 5 matches the first through hole 41 and has a clearance fit.

[0063] As a preferred embodiment, the longitudinal cross section of the second through hole 42 is polygonal or circular; the shape of the end of the second cross beam 6 matches the second through hole 42 and has a clearance fit.

[0064] In the above embodiments, the cross sections of the first beam 5 and the second beam 6 may be of different geometric shapes, such as polygonal or circular, but the overall width cannot exceed 40% of the width of the column 4, and the length is determined according to production needs.

[0065] As a preferred embodiment, the column 4 is provided with a third through hole 44 arranged along the Z direction.

[0066] In the above embodiment, by providing the third through hole 44 in the column 4 , the weight of the column 4 can be reduced and the material can be saved.

[0067] As a preferred embodiment, the first cross beam 5 is provided with a fourth through hole 51 arranged along the length direction thereof; the second cross beam 6 is provided with a fifth through hole 61 arranged along the length direction thereof.

[0068] In the above embodiment, by providing the fourth through hole 51 on the first beam 5 and the fifth through hole 61 on the second beam 6 , the weight of the first beam 5 and the second beam 6 can be reduced, thus saving materials.

[0069] As a preferred embodiment, the thickness of the first side plate 2 is 3-5 mm, the thickness of the second side plate 3 is 3-5 mm, and in the assembled state, the first side plate 2 and a straight groove 43 of the column 4 have a clearance fit, and the second side plate 3 and another straight groove 43 of the column 4 have a clearance fit.

[0070] As a preferred embodiment, the thickness of the bottom plate 1 is 5-8 mm.
