[0029] Please refer to Figures 1 to 6 together, and now the kiln furniture provided by the embodiments of the present utility model will be described.

[0030] As Figure 1 and Figure 2 shown, the kiln furniture of the embodiment of the present utility model includes: a kiln furniture body 100; two or more kiln furniture bodies 100 can be stacked, as Figure 6 shown;

[0031] Among them, a downward-facing first positioning hole 124 is designed at the bottom of each kiln furniture body 100; an upward-facing first positioning post 123 is designed at the top of each kiln furniture body 100; the kiln furniture body 100 can support the product 500, the size of the first positioning hole 124 is larger than that of the first positioning post 123, and when stacking the kiln furniture, the first positioning post 123 extends into the first positioning hole 124 of another kiln furniture body 100, as Figure 6 shown, to realize the positioning and stacking of the kiln furniture, so that the stacked multiple kiln furniture will not be displaced or collapsed randomly during the transportation by the kiln car, prevent the product 500 on the kiln furniture from falling, and ensure the transportation safety.

[0032] During use, the product 500 is placed on the kiln furniture body 100. Subsequently, the transportation robot transports the kiln furniture body 100 with the product 500 onto the kiln car. Then, the transportation robot stacks multiple kiln furniture bodies 100 with the product 500 on the kiln car in sequence, forming a multi-layer kiln furniture stacking state, saving space and achieving the purpose of stacking multiple kiln furniture on the kiln car. After stacking is completed, the kiln car can transport the stacked multiple kiln furniture into the kiln furnace for sintering.

[0033] The kiln furniture of this embodiment can load the product 500. Subsequently, the transportation robot can carry and place the kiln furniture with the product 500 on the kiln rack and stack them into multiple layers of kiln furniture in sequence to achieve the purpose of loading the product 500 onto the vehicle. Therefore, in the entire process, the steps of manually loading the product 500 onto the vehicle one by one are reduced, saving manpower, reducing labor costs, reducing the probability of safety accidents, and eliminating potential safety hazards; moreover, each kiln furniture body 100 can be separated individually, abandoning the design of using an integral frame in the prior art. The kiln furniture body 100 adopts a modular design and has the characteristics of maintainability, scalability, reusability, and independence. When a part of the kiln furniture body 100 is damaged, only the damaged part needs to be replaced, and there is no need to perform overall maintenance or overall scrapping of all the kiln furniture, saving the cost of the kiln car.

[0034] In some embodiments of the present utility model, referring to Figures 2 to 5 , the kiln furniture body 100 includes multiple combined beams 110 and multiple combined brackets 120; the multiple combined brackets 120 are arranged in parallel along the first straight line direction, the combined beam 110 is designed between two adjacent combined brackets 120, and both ends of the combined beam 110 are respectively connected to the tops of the two combined brackets 120; at least two combined beams 110 arranged in parallel along the second straight line direction are provided between two adjacent combined brackets 120, and two adjacent combined beams 110 are used to cooperate to support the product 500; the first positioning post 123 is designed on the top of the combined bracket 120, and the first positioning hole 124 is designed on the bottom of the combined bracket 120.

[0035] Referring to Figures 2 to 5, multiple combined brackets 120 of a kiln furniture body 100 are arranged in parallel, and there are at least two combined beams 110 arranged in parallel between two adjacent combined brackets 120. There is a gap for placing the product 500 between the two combined beams 110, and there is also a gap for placing the product 500 between the two combined brackets 120. Then, at least two combined beams 110 and the two combined brackets 120 form a support kiln furniture that can surround the product 500. This kiln furniture uses the two combined beams 110 to support the product 500 to achieve the purpose of fixing the product 500, so that the transportation robot can carry the kiln furniture body 100 with the product 500 onto the kiln rack 200. The first positioning hole 124 and the first positioning post 123 are designed on the combined bracket 120, which can enable the combined bracket 120 to not only bear the pressure from the combined beam 110, but also bear the pressure from the upper kiln furniture body 100, so as to reduce the pressure on the combined beam 110 and avoid deformation of the combined beam 110. Optimally, referring to Figure 1 and Figure 2 , the first straight line direction is perpendicular to the second straight line direction, so that the combined beam 110 and the combined bracket 120 cooperate to form a square kiln furniture for stacking.

[0036] In some embodiments of the present invention, referring to Figures 2 to 5 , the combined beam 110 is designed with a positioning socket hole 111; the combined beam 110 is sleeved with the first positioning post 123 through the positioning socket hole 111, and the first positioning post 123 passes through the positioning socket hole 111. That is, the combined beam 110 is combined and sleeved on the combined bracket 120. When in use, the combined beam 110 and the combined bracket 120 are combined into a kiln furniture body 100 that can support the product 500; when not in use, the kiln furniture body 100 can be disassembled for storage. By designing the first positioning post 123 to pass through the positioning socket hole 111, it can ensure that the top of the combined kiln furniture body 100 has the first positioning post 123 that can be inserted into the first positioning hole 124, ensuring the positioning and assembly function of the kiln furniture body 100.

[0037] In some embodiments of the present invention, referring to Figures 2 to 5, the combined support 120 includes a connecting beam 122 and at least two support feet 121; the tops of at least two of the support feet 121 are connected by the connecting beam 122, and the lower end of at least one of the support feet 121 is designed with the first positioning hole 124, and the upper end of the corresponding support foot 121 is designed with a first positioning post 123. That is, the support foot 121 is the main stress position of the combined support 120, and the support foot 121 is parallel to the length direction of the first positioning post 123 to ensure more stable stress of the support foot 121. Optimally, the number of combined supports 120 for each kiln furniture body 100 is two, the number of combined beams 110 is two, the number of support feet 121 on the combined support 120 is two, and the upper and lower ends of each support foot 121 are respectively designed with a first positioning post 123 and a first positioning hole 124, so that the combined support 120 forms an H-shaped support for better positioning and stacking. Among them, in order to increase the support area, as Figure 1 , Figure 2 shown, the combined beam 110 is a flat beam, and the upper side of the flat beam is used to support the product 500.

[0038] It can be mentioned that in the static load bearing test of a single kiln furniture body 100 combined by H-shaped supports in this embodiment at room temperature, the H-shaped support can bear the product weight of 1.5 tons, that is, the ratio of the mass of the kiln furniture to the product is much less than 1; therefore, when the product quality is greater, the energy consumption of the kiln furniture is lower, and the firing of the product will be more energy-saving. Moreover, the higher the bearing capacity of the H-shaped support, the more kiln furniture bodies 100 can be stacked, which can not only improve the stability of the stacked kiln furniture bodies 100, but also improve the volume ratio of the kiln car, achieving the effect of energy conservation and cost reduction.

[0039] In some embodiments of the present invention, referring to Figures 2 to 5 , the kiln furniture body 100 further includes: a dirt-proof dropping plate 130; the dirt-proof dropping plate 130 is connected to the combined support 120, and the dirt-proof dropping plate 130 is located below the combined beam 110, and the dirt-proof dropping plate 130 is used to carry the dirt dropped by the product 500. The dirt comes from the mud particles of the product itself, the dirt dropped during the firing shrinkage of the glaze embryo, and the dirt generated by the friction between the kiln furniture bodies 100. That is, the kiln furniture body 100 has a dirt-proof dropping plate 130, and the dirt-proof dropping plate 130 is located below the product 500 to prevent the dirt from falling on the product 500 below.

[0040] In some embodiments of the present invention, referring to Figures 2 to 5, the kiln furniture body 100 further includes: at least two simply supported beams 140; the simply supported beams 140 are connected to the combined support 120, and the simply supported beams 140 are located below the combined beam 110; at least two of the simply supported beams 140 form a support for supporting the anti-fouling plate 130. That is, the simply supported beams 140 are used to form a support for supporting the anti-fouling plate 130, and the simply supported beams 140 are connected to the combined support 120, so as to prevent the simply supported beams 140 from affecting the load-bearing capacity of the combined beam 110 and ensure that the combined beam 110 can support the product 500. On this basis, the combined support 120 is designed with at least two support through holes 126, and the support through holes 126 are in one-to-one correspondence with the simply supported beams 140. That is, the support through holes 126 are inserted with the simply supported beams 140. Since there are at least two simply supported beams 140, there are also two corresponding support through holes 126.

[0041] In some embodiments of the present invention, referring to Figures 2 to 5 , in order to reduce the weight of the combined support 120, the support through holes 126 penetrate the combined support 120, and the support through holes 126 are waist-shaped grooves. The two ends of the simply supported beam 140 are respectively inserted into the support through holes 126 of two adjacent combined supports 120. Among them, the support through holes 126 are designed on the support feet 121. The simply supported beam 140 spans between two adjacent combined supports 120, and both ends of the simply supported beam 140 are inserted into the combined support 120 through the support through holes 126. Since the support through holes 126 are waist-shaped grooves with a length parallel to the length direction of the support feet 121, it is convenient for the simply supported beam 140 to better pass through the support through holes 126, and it is convenient for the simply supported beam 140 to be directly inserted into the support through holes 126 in the combined kiln furniture body 100 to form a support frame, which is convenient for assembly.

[0042] In some embodiments of the present invention, referring to Figures 2 to 5 , a fork arm avoidance position 160 is designed at the bottom of the kiln furniture body 100. The fork arm avoidance position 160 of the kiln furniture body 100 can allow the fork arm of the handling mechanism to extend in. The handling mechanism may include a handling robot, and the handling robot may be a multi-axis robotic arm, which can drive the fork arm to transport the kiln furniture body 100 with the product 500 to the kiln car, facilitating loading.

[0043] In some embodiments of the present invention, referring to Figures 2 to 5, a fork - arm positioning portion 125 is designed on the upper side of the kiln furniture body 100 at the fork - arm avoidance position 160. The fork - arm positioning portion 125 can be in the shape of a hole, and the fork - arm positioning portion 125 is an insertion positioning hole. Such a design can reduce the weight of the combined support 120, reduce the weight of each kiln furniture body 100, and reduce energy consumption. The fork - arm of the handling mechanism can be designed with a positioning post that can be inserted into the fork - arm positioning portion 125 to position and grasp the kiln furniture body 100, and can also prevent the kiln furniture body 100 from shifting during transportation, ensuring precise transportation and guaranteeing transportation safety.

[0044] Among them, it should be noted that the combined beam 110 can be made of silicon carbide material and formed into a hollow thin - wall structure to meet the load - bearing strength and achieve the purpose of light weight. To meet the requirements of support stability and light weight, the combined support 120 is made of mullite material and formed into a hollow structure, thereby reducing the weight of the entire kiln furniture, reducing the mass ratio with the product 500, and improving the fuel combustion efficiency.

[0045] Refer to Figures 2 to 5 , in some embodiments of the present utility model, it further includes: a silicon carbide plate 150; the silicon carbide plate 150 is placed across between two adjacent combined beams 110. The silicon carbide plate 150 is used to assist in supporting the product 500, and the shape of the silicon carbide plate 150 can be changed according to the sintered product so that the kiln furniture can support more types of basins.

[0046] Refer to Figures 2 to 5 , in some embodiments of the present utility model, in order to prevent the two - side edges of the silicon carbide plate 150 from protruding above the upper side surface of the combined beam 110, a support sink 112 for accommodating the two - side edges of the silicon carbide plate 150 is designed on the upper side of the combined beam 110, and the support sink 112 is designed on the central side of the combined beam 110 facing the silicon carbide plate 150. By designing the support sink 112, it is possible to prevent the two - side edges of the silicon carbide plate 150 from protruding above the upper side surface of the combined beam 110, so that the combined beam 110 can better support the product 500 and achieve a better support purpose.

[0047] Refer to Figure 2 、 Figure 5 , in some embodiments of the present utility model, it further includes: a plurality of silicon carbide bars 170; the support sink 112 extends along the length direction of the combined beam 110, and the silicon carbide bars 170 are clamped with the support sink 112. The silicon carbide bars 170 cooperate with the silicon carbide plate 150 to assist in supporting the product 500 together, so that the kiln furniture can support more basins with different shapes. Among them, card slots can be designed in the support sink 112, and the silicon carbide bars 170 are designed with blocks that can extend into the card slots to better fix the silicon carbide bars 170 and prevent the silicon carbide bars 170 from falling randomly.

[0048] Refer to Figure 3 andFigure 4 In some embodiments of the present utility model, the connecting beam 122 is designed with weight-reducing hollow holes 127, which can reduce the weight of the combined support 120 and improve the fuel combustion efficiency.

[0049] Refer to Figures 1 to 4 In some embodiments of the present utility model, in order to facilitate the installation and stacking of the combined beam 110, the top end of the first positioning post 123 is designed with a chamfer 128. Designing the chamfer 128 on the first positioning post 123 can better fit the combined beam 110 onto the first positioning post 123, and also facilitate the alignment of the first positioning hole 124 of the combined support 120 with the first positioning post 123, making it convenient to stack the kiln furniture.

[0050] Refer to Figure 4 In some embodiments of the present utility model, the combined support 120 is designed with a collecting sink 129 at the edge of the first positioning post 123. The collecting sink 129 is used to collect the dust generated from the cooperation between the first positioning post 123 and the first positioning hole 124, preventing the dust from scattering in the workshop and keeping the workshop clean.

[0051] The present utility model also provides a kiln car, which includes the kiln furniture and the kiln rack as described above, and a plurality of kiln furniture are stacked on the kiln rack. Among them, the kiln furniture can load the product 500. Subsequently, the transport robot can carry and place the kiln furniture with the product 500 on the kiln rack and stack them into multiple layers of kiln furniture in sequence to achieve the purpose of loading the product 500 onto the vehicle. Therefore, in the whole process, the steps of manually loading the product 500 onto the vehicle one by one are reduced, saving manpower, reducing the labor cost, reducing the probability of safety accidents, and eliminating potential safety hazards. Moreover, each kiln furniture body 100 on the kiln car can be separated independently. When a part of the kiln furniture body 100 is damaged, only the damaged part needs to be replaced, saving the cost of the kiln car.

[0052] In summary, the kiln furniture of this embodiment can load the product 500. Subsequently, the transport robot can carry and place the kiln furniture with the product 500 on the kiln rack and stack them into multiple layers of kiln furniture in sequence to achieve the purpose of loading the product 500 onto the vehicle. Therefore, in the whole process, the steps of manually loading the product 500 onto the vehicle one by one are reduced, saving manpower, reducing the labor cost, reducing the probability of safety accidents, and eliminating potential safety hazards. Moreover, each kiln furniture body 100 can be separated independently, abandoning the design of the integral frame in the prior art.
