[0023] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.
[0024] like Figure 1-5 As shown, a combined kiln car includes a base frame 1, with baffles 3 on the two side walls of the base frame 1 located in the direction of kiln car movement. The base frame 1 and the two baffles 3 form a bearing area for supporting brick blanks. A reinforcing block 2 is snapped onto the baffle 3, and a first snap-fit groove 20 is provided on the side of the reinforcing block 2 facing the bearing area. An insulation layer is laid on the base frame 1, and a bearing layer is laid on the insulation layer. The bearing layer is snapped into the first snap-fit groove 20. A snap-fit gap 52 is provided in the middle of the bearing layer. A wear-resistant layer is provided on the bearing layer. A snap-fit protrusion 60 is provided at the bottom of the wear-resistant layer. The snap-fit protrusion 60 is snapped into the snap-fit gap 52. A second snap-fit groove 21 is provided at the top of the reinforcing block 2. L-shaped snap-fit plates 61 are provided on both sides of the wear-resistant layer facing the reinforcing block 2. The L-shaped snap-fit plates 61 are snapped into the second snap-fit groove 21.
[0025] The base frame 1 is in the form of a frame, and the bottom is equipped with rollers 11.
[0026] The direction of kiln car movement is defined as the front-to-back direction, meaning the two walls along the direction of kiln car movement represent the left and right walls.
[0027] In other embodiments, a front limiting plate and a rear limiting plate may be provided on the front and rear side walls of the base frame 1.
[0028] The baffle 3, the front limit plate, and the rear limit plate can all be installed on the base frame 1 by welding or bolt connection.
[0029] A reinforcing block 2 is provided on the baffle 3. The reinforcing block 2 is used to increase the structural strength of the entire kiln car. In fact, it is used to cooperate with other components that increase the structural strength of the kiln car, thereby ensuring the coordination strength of each structure in the kiln car and ensuring that the structures are more compact.
[0030] The insulation layer is used to prevent temperature flow between the upper and lower sides of the kiln car, ensuring the firing effect of the brick blanks; the reinforcing block 2 is located above the insulation layer and can play a certain role in pressing down the insulation layer.
[0031] The bearing layer is used to increase the load-bearing capacity of the kiln car. The edge of the bearing layer is engaged in the first engagement groove 20 in the fixing block, which can play a certain role in fixing the bearing layer.
[0032] The length direction of the first card slot 20 is consistent with the front-to-back direction, which can restrict the left-to-right and up-to-down movement of the bearing layer. Of course, the front-to-back movement of the bearing layer is limited by the positioning plate.
[0033] The wear-resistant layer is located above the bearing layer. The snap-fit protrusion 60 at the bottom of the wear-resistant layer cooperates with the snap-fit gap 52 on the bearing layer. Preferably, the length direction of the snap-fit gap 52 is set along the left and right direction so as to be perpendicular to the first snap-fit groove 20 in space, thereby ensuring the connection strength of the entire kiln car.
[0034] One end of the L-shaped snap-fit plate 61 is connected to the wear-resistant layer, and the other end is connected to the second snap-fit groove 21 provided on the fixing block.
[0035] Throughout the kiln car, the insulation layer, load-bearing layer, and wear-resistant layer are all connected in a snap-fit manner to form an integrated structure, which not only meets the usage requirements of the kiln car but also facilitates subsequent maintenance.
[0036] In some further embodiments, the bottom of the reinforcing block 2 is provided with a third snap-fit groove 22, which snaps into the upper edge of the baffle 3; there are multiple reinforcing blocks 2, which are arranged along the length of the baffle 3 and abut against each other.
[0037] There are multiple reinforcing blocks 2, and the multiple reinforcing blocks 2 are engaged with the baffle 3 through the third snap-fit groove 22 provided at their bottom; the multiple reinforcing blocks 2 abut against each other to ensure the stability between the reinforcing blocks 2.
[0038] In some further embodiments, the insulation layer includes a plurality of insulation boards 4, which are arranged in abutment along the arrangement direction of the two baffles 3, i.e., in the left-right direction.
[0039] For example, the insulation board 4 can specifically be a rock wool board.
[0040] In some further embodiments, the support layer includes two sets of support modules, which are mirror-arranged along the central parallel plane between the two baffles 3. Each support module includes multiple support units spaced apart along the length of the baffle 3, with a snap-fit gap 52 formed between the two support units. Each support unit includes multiple support blocks 5 arranged along the arrangement direction of the two baffles 3. One side wall of each support block 5 is provided with a snap-fit strip 50, and the other opposite side wall is provided with a fourth snap-fit groove 51. The snap-fit strip 50 on one support block 5 engages with the fourth snap-fit groove 51 on the adjacent support block 5. The snap-fit strip 50 on the support block 5 closest to the baffle 3 engages with the first snap-fit groove 20.
[0041] Each bearing block 5 in the bearing unit is engaged with each other by a snap-fit strip 50 and a fourth snap-fit groove 51. A gap is left between two adjacent bearing units, namely the snap-fit gap 52 for the wear-resistant layer to snap on.
[0042] The snap-fit strip 50 on one of the bearing blocks 5 near the fixed block on any bearing module engages with the first snap-fit groove 20 to achieve the engagement between the bearing module and the fixed block.
[0043] The design of the load-bearing module, load-bearing unit, and load-bearing block 5 can ensure the strength of the entire kiln car and facilitate subsequent disassembly, replacement, and maintenance.
[0044] In some further embodiments, a plug-in plate is also included; the two fourth snap-fit slots 51 in the two adjacent carrier blocks 5 of the two carrier modules together form a plug-in slot, which is plugged into the plug-in plate.
[0045] The two sets of mirror-symmetrical load-bearing modules are matched and positioned by interlocking slots and interlocking plates to enhance the overall integrity of the load-bearing layer.
[0046] For example, the support block 5 can be a high-alumina brick.
[0047] In some further embodiments, the wear-resistant layer includes four abutting wear-resistant plates 6, with an L-shaped snap-fit plate 61 disposed on one side wall of the wear-resistant plate 6 near the baffle 3.
[0048] There are four wear-resistant plates 6, arranged in a 2x2 square pattern. This not only meets the requirements for future replacement, but also reduces the number of gaps to a certain extent, avoiding collisions with the gaps when loading and unloading brick blanks.
[0049] For example, the wear-resistant layer is the entire kiln car platform layer, which is in direct contact with the brick blank, and the material of the wear-resistant plate 6 can be the same as the material of the bearing block 5.
[0050] In some further embodiments, a fixed sand sealing plate 30 is provided at the bottom of both baffles 3.
[0051] For example, the baffle 3 is integrated with the sand seal plate.
[0052] When the kiln car is in motion, the sand sealing plate is located in the sand sealing groove to ensure the temperature of the upper area of the kiln car.
[0053] In some further embodiments, a movable sand seal plate 31 is slidably provided on one side of the two fixed sand seal plates 30 facing away from each other in the vertical direction.
[0054] To further ensure the temperature of the upper layer of the kiln car, an adjustable movable sand seal plate 31 is installed. When the required temperature is high, the movable sand seal plate 31 is adjusted downward to form a double sand seal plate for heat insulation. When the required temperature is low, the movable sand seal plate 31 is adjusted upward.
[0055] In some further embodiments, the fixed sand seal plate 30 is provided with a slot 300, the length direction of the slot 300 is consistent with the vertical direction, and the movable sand seal plate 31 is provided with a fixing hole corresponding to the slot 300, the fixing hole and the slot 300 are connected by bolts and nuts.
[0056] The adjustment of the movable sand seal plate 31 is achieved through the slot 300. Specifically, during adjustment, loosen the nut on the bolt, manually adjust the height of the movable sand seal plate 31, and after the height is appropriate, tighten the nut on the bolt to achieve adjustment.
[0057] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
