Description

Technical Field

[0001] This utility model relates to the technical field of kiln equipment, and in particular to a shuttle kiln and shuttle kiln system combined with roller conveyor. Background Technology

[0002] A shuttle kiln is an intermittent firing kiln (meaning its production process is not continuous but carried out in batches and stages, including loading, firing, and unloading). Products to be fired are pushed into the kiln by kiln cars, and then pulled out in the opposite direction after firing. It is widely used in industries such as ceramics, glass, and refractory materials, and is particularly suitable for small-batch, multi-variety production needs. However, for ceramic tiles, the stationary position within the shuttle kiln cannot meet the requirements of the tile firing process. Therefore, when firing tests of ceramic tiles according to a formula are needed, only short roller kilns can be used. However, even short roller kilns occupy a large space (with preheating, firing, and cooling zones distributed in a front, middle, and rear pattern), and the intermittent firing tests, with their long heating and cooling times, significantly extend the intermittent firing time, resulting in low firing efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a shuttle kiln combined with roller conveyors, which can not only fire ceramic tiles, but also occupy less space, have higher firing efficiency, and lower cost.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A shuttle kiln combined with roller conveyors includes a shuttle kiln body, a heating module, a cooling module, and a first conveying roller module;

[0006] The main body of the shuttle kiln is provided with a furnace cavity that serves as a preheating zone, a firing zone, and a cooling zone.

[0007] The heating module, cooling module, and first roller conveyor module are all installed inside the furnace cavity of the shuttle kiln body;

[0008] The first conveyor roller module includes a conveyor roller assembly for conveying products and a transmission unit for driving the conveyor roller assembly.

[0009] The conveyor roller assembly, heating module, and cooling module are all evenly arranged along the length of the furnace cavity.

[0010] The heating module is positioned above and below the conveyor roller assembly;

[0011] The cooling module is positioned above and below the conveyor roller assembly;

[0012] The heating and cooling modules are spaced apart.

[0013] In this technical solution, the first conveying roller module reciprocates to convey the ceramic tiles placed in the furnace cavity, thereby meeting the conditions for intermittent ceramic tile firing in a shuttle kiln. In addition, compared to roller kilns which require the preheating zone, firing zone, and cooling zone to be distributed according to the front, middle, and rear positions, the conveying roller group, heating module, and cooling module in this technical solution are all evenly arranged along the length of the furnace cavity. That is, only one furnace cavity is needed, and there is no need for partitioning, so that ceramic tile preheating, firing, and cooling operations can be realized, thereby greatly reducing the space occupied by the kiln.

[0014] The heating modules are arranged above and below the conveyor roller assembly. They can not only heat the upper and lower surfaces of the ceramic tiles placed on the conveyor roller assembly at the same time, but also shorten the heating time in the furnace cavity during the preheating and firing stages, thereby improving firing efficiency.

[0015] The cooling module is located above and below the conveyor roller assembly, and can simultaneously supply cold air to the upper and lower areas of the conveyor roller assembly, shortening the cooling time in the furnace cavity during the cooling stage of the firing process, thereby improving firing efficiency.

[0016] The heating and cooling modules are spaced apart to enable rapid heating and rapid cooling.

[0017] Furthermore, the heating module includes electric heating rod groups respectively arranged above and below the conveyor roller group, and both groups of electric heating rod groups are evenly arranged along the length direction of the furnace cavity.

[0018] The distance between the electric heating rod group located above the conveyor roller group and the conveyor roller group is greater than the distance between the electric heating rod group located below the conveyor roller group and the conveyor roller group. This makes the shortest distance between the electric heating rod group located above the conveyor roller group and the upper surface of the tile equal to the shortest distance between the electric heating rod group located below the conveyor roller group and the lower surface of the tile, thus achieving uniform heating of the upper and lower surfaces of the tile.

[0019] Furthermore, the cooling module includes a blower and an air duct;

[0020] The air supply duct is connected to the furnace cavity;

[0021] The blower is connected to the air supply duct, which delivers external cold air into the furnace cavity.

[0022] Furthermore, the air supply duct includes a main duct, an upper branch duct equipped with valves, and a lower branch duct;

[0023] The main pipeline is connected to the blower;

[0024] The upper branch pipe is connected to the main pipe and enters the furnace cavity to deliver cold air to the area above the conveyor roller assembly;

[0025] The lower branch pipe is connected to the main pipe and enters the furnace cavity to deliver cold air to the area below the conveyor roller assembly.

[0026] In this technical solution, during the preheating and firing stages of the firing process, the valves of both the upper and lower distribution pipes are closed. During the cooling stage of the firing process, the valves of both the upper and lower distribution pipes are open, allowing cold air to be supplied to the upper and lower areas of the conveyor roller assembly, respectively. This shortens the cooling time within the furnace cavity during the cooling stage of the firing process, thereby improving firing efficiency.

[0027] Furthermore, the upper distribution pipe includes a first sub-upper distribution pipe and a second sub-upper distribution pipe, both of which are connected to the main pipe and enter the furnace cavity from both sides of the furnace cavity respectively, delivering cold air to the area above the conveyor roller assembly;

[0028] The lower distribution pipe includes a first sub-lower distribution pipe and a second sub-lower distribution pipe, both of which are connected to the main pipe and enter the furnace cavity from both sides of the furnace cavity respectively, delivering cold air to the area below the conveyor roller group.

[0029] In this technical solution, by coordinating the first sub-upper branch pipe, the second sub-upper branch pipe, the first sub-lower branch pipe, and the second sub-lower branch pipe, cold air is delivered to the tiles from multiple directions, which can improve the cooling effect of the tiles.

[0030] Furthermore, the air supply duct also includes an upper cooling air duct and a lower cooling air duct;

[0031] The upper cooling air duct spans above the conveyor roller assembly, and its two ends are respectively connected to the first sub-upper pipe and the second sub-upper pipe that enter the furnace cavity from both sides of the furnace cavity. The upper cooling air duct has upper cooling air holes that are evenly distributed along its length.

[0032] The lower cooling air duct spans below the conveyor roller assembly, and its two ends are respectively connected to the first and second sub-lower pipes that enter the furnace cavity from both sides of the furnace cavity. The lower cooling air duct has lower cooling air holes that are evenly distributed along its length.

[0033] In this technical solution, cold air can be directly and evenly supplied to the upper and lower surfaces of the ceramic tile through the upper and lower cold air holes, respectively, to achieve a rapid cooling effect.

[0034] Furthermore, the shuttle kiln body is equipped with an exhaust chimney, which has an on / off valve and is located at the top center of the furnace cavity. During the preheating and firing stages of the firing process, the on / off valve of the exhaust chimney is in the closed state. During the cooling stage of the firing process, the on / off valve of the exhaust chimney is in the open state. Through the cooperation of the blower, air supply duct, and exhaust chimney, a convective environment is provided to the furnace cavity, with cold air entering from both sides and hot air being exhausted from the center, thereby improving the heat transfer rate and shortening the cooling time.

[0035] Furthermore, the kiln wall of the shuttle kiln body has a three-layer structure: the inner layer is a zirconium-containing ceramic fiber layer, the interlayer is a standard ceramic fiber layer, and the outer layer is a rock wool layer.

[0036] Both the kiln top and the kiln bottom have a three-layer structure: the inner layer is a zirconium-containing ceramic fiber layer, and the outer two layers are standard ceramic fiber layers.

[0037] The kiln door has a two-layer structure: the inner layer is a zirconium-containing ceramic fiber layer, and the outer layer is a standard ceramic fiber layer.

[0038] The kiln walls, kiln roof, kiln bottom, and kiln door work together to improve the heat preservation performance of the furnace cavity, thereby shortening the heating time in the furnace cavity during the preheating and firing stages and thus improving firing efficiency.

[0039] Furthermore, the shuttle kiln body is equipped with barrier panels on both outer sides, which can effectively prevent accidental contact with the electrical components of the electric heating rod, and at the same time facilitate the upward flow of hot air in the kiln body, reducing the side temperature.

[0040] Furthermore, the present invention also includes a shuttle kiln system, which includes an external conveying device and the aforementioned shuttle kiln combined with roller conveyors.

[0041] The external conveying device for the kiln includes a movable carriage and a second conveying roller module;

[0042] The second conveyor roller module is mounted on a mobile carriage.

[0043] Compared with existing technologies, the principles and advantages of this technical solution are as follows:

[0044] 1. The first conveying roller module reciprocates the ceramic tiles placed in the furnace cavity, which can meet the conditions for intermittent ceramic tile firing in a shuttle kiln. In addition, compared with the roller kiln, which requires the preheating zone, firing zone and cooling zone to be distributed according to the front, middle and rear position relationship, the conveying roller group, heating module and cooling module in this technical solution are all evenly arranged along the length of the furnace cavity. That is, only one furnace cavity is needed, and there is no need to divide it, so that the ceramic tile preheating, firing and cooling operations can be realized, thereby greatly reducing the space occupied by the kiln.

[0045] The heating modules are arranged above and below the conveyor roller assembly. They can not only heat the upper and lower surfaces of the ceramic tiles placed on the conveyor roller assembly at the same time, but also shorten the heating time in the furnace cavity during the preheating and firing stages, thereby improving firing efficiency.

[0046] The cooling module is located above and below the conveyor roller assembly, and can simultaneously supply cold air to the upper and lower areas of the conveyor roller assembly. This can shorten the cooling time in the furnace cavity during the cooling stage of the firing process, thereby improving firing efficiency.

[0047] The heating and cooling modules are spaced apart to enable rapid heating and rapid cooling.

[0048] 2. The distance between the electric heating rod group above the conveyor roller group and the conveyor roller group is greater than the distance between the electric heating rod group below the conveyor roller group and the conveyor roller group. This makes the shortest distance between the electric heating rod group above the conveyor roller group and the upper surface of the tile equal to the shortest distance between the electric heating rod group below the conveyor roller group and the lower surface of the tile, thus achieving uniform heating of the upper and lower surfaces of the tile.

[0049] 3. During the preheating and firing stages of the firing process, the valves of both the upper and lower distribution pipes are closed. During the cooling stage of the firing process, the valves of both the upper and lower distribution pipes are open. Cold air is supplied to the upper and lower areas of the conveyor roller assembly through the upper and lower distribution pipes, respectively, which can shorten the cooling time in the furnace cavity during the cooling stage of the firing process, thereby improving firing efficiency.

[0050] 4. The upper and lower cold air vents can directly and evenly provide cold air to the upper and lower surfaces of the tiles, respectively, to achieve a rapid cooling effect.

[0051] 5. During the preheating and firing stages of the firing process, the exhaust chimney valve is in the closed state. During the cooling stage of the firing process, the exhaust chimney valve is in the open state. Through the cooperation of the blower, air duct, and exhaust chimney, a convective environment is provided for the furnace cavity, with cold air entering from both sides and hot air being exhausted from the center, thereby improving the heat transfer rate and shortening the cooling time.

[0052] 6. The external conveying device allows for flexible transfer of ceramic tile blanks from other conveying lines to the shuttle kiln for firing and testing. Attached Figure Description

[0065] Specifically, in this embodiment, the upper distribution pipe 7 includes a first sub-upper distribution pipe 9 and a second sub-upper distribution pipe 10, both of which are connected to the main pipe 6 and enter the furnace cavity 1 from both sides, respectively, to deliver cold air to the area above the conveyor roller group 2; the lower distribution pipe 8 includes a first sub-lower distribution pipe 17 and a second sub-lower distribution pipe 18, both of which are connected to the main pipe 6 and enter the furnace cavity 1 from both sides, respectively, to deliver cold air to the area below the conveyor roller group 2. The first sub-upper distribution pipe 9 and the second sub-upper distribution pipe 10 are positioned between two corresponding electric heating rods above the conveyor roller group 2; the first sub-lower distribution pipe 17 and the second sub-lower distribution pipe 18 are positioned between two corresponding electric heating rods below the conveyor roller group 2.

[0066] Specifically, the air supply duct in this embodiment further includes an upper cooling air duct 11 and a lower cooling air duct 12; the upper cooling air duct 11 spans above the conveyor roller group 2, and its two ends are respectively connected to the first sub-upper branch pipe 9 and the second sub-upper branch pipe 10 entering the furnace cavity 1 from both sides of the furnace cavity 1, and the upper cooling air duct 11 has upper cooling air holes evenly distributed along its length direction; the lower cooling air duct 12 spans below the conveyor roller group 2, and its two ends are respectively connected to the first sub-lower branch pipe 17 and the second sub-lower branch pipe 18 entering the furnace cavity 1 from both sides of the furnace cavity 1, and the lower cooling air duct 12 has lower cooling air holes evenly distributed along its length direction.

[0067] Specifically, in this embodiment, the shuttle kiln body is provided with an exhaust chimney 13, which is equipped with a switch valve and is located at the top of the middle of the furnace chamber 1.

[0068] Specifically, in this embodiment, the kiln wall of the shuttle kiln body has a three-layer structure: the inner layer is a zirconium-containing ceramic fiber layer, the interlayer is a standard ceramic fiber layer, and the outer layer is a rock wool layer; the kiln top and kiln bottom also have a three-layer structure: the inner layer is a zirconium-containing ceramic fiber layer, and the outer two layers are standard ceramic fiber layers; the kiln door has a two-layer structure: the inner layer is a zirconium-containing ceramic fiber layer, and the outer layer is a standard ceramic fiber layer; the kiln wall, kiln top, kiln bottom, and kiln door work together to improve the heat preservation performance of the furnace cavity 1.

[0069] Specifically, in this embodiment, barrier panels 14 are provided on both outer sides of the shuttle kiln body.

[0070] In this embodiment, the working principle of the shuttle kiln combined with the roller conveyor is as follows:

[0071] The first conveying roller module reciprocates to transport the ceramic tiles placed in the furnace chamber 1, thereby meeting the conditions for intermittent ceramic tile firing in a shuttle kiln. In addition, compared to roller kilns which require the preheating zone, firing zone, and cooling zone to be distributed according to the front, middle, and rear positions, in this embodiment, the conveying roller group 2, heating module, and cooling module are all evenly arranged along the length of the furnace chamber 1. That is, only one furnace chamber 1 is needed, and there is no need for partitioning, so that ceramic tile preheating, firing, and cooling operations can be realized, thereby greatly reducing the space occupied by the kiln.

[0072] By heating the ceramic tiles placed on the conveyor roller group 2 with two sets of electric heating rods 4 located above and below the conveyor roller group 2, the heating time in the furnace cavity 1 during the preheating and firing stages can be shortened, thereby improving the firing efficiency.

[0073] The distance between the electric heating rod group 4 located above the conveyor roller group 2 and the conveyor roller group 2 is greater than the distance between the electric heating rod group 4 located below the conveyor roller group 2 and the conveyor roller group 2. This makes the shortest distance between the electric heating rod group 4 located above the conveyor roller group 2 and the upper surface of the tile equal to the shortest distance between the electric heating rod group 4 located below the conveyor roller group 2 and the lower surface of the tile, thereby achieving uniform heating of the tile.

[0074] During the preheating and firing stages of the firing process, the valves of the upper branch pipe 7 and the lower branch pipe 8 are both closed. During the cooling stage of the firing process, the valves of the upper branch pipe 7 and the lower branch pipe 8 are both open, and cold air is supplied to the upper and lower areas of the conveyor roller group 2 through the upper branch pipe 7 and the lower branch pipe 8, respectively. This can shorten the cooling time in the furnace cavity 1 during the cooling stage of the firing process, thereby improving the firing efficiency.

[0075] Furthermore, by coordinating the first sub-upper branch pipe 9, the second sub-upper branch pipe 10, the first sub-lower branch pipe 17, and the second sub-lower branch pipe 18, cold air is delivered to the tiles from multiple directions, which can improve the cooling effect of the tiles.

[0076] The upper and lower cold air vents can directly and evenly provide cold air to the upper and lower surfaces of the tiles, respectively, achieving a rapid cooling effect.

[0077] During the preheating and firing stages of the firing process, the valve of the exhaust chimney 13 is in the closed state. During the cooling stage of the firing process, the valve of the exhaust chimney 13 is in the open state. Through the cooperation of the blower 5, the air supply duct, and the exhaust chimney 13, a convective environment is provided for the furnace cavity 1, with cold air entering from both sides and hot air being exhausted from the middle, thereby improving the heat transfer rate and shortening the cooling time.

[0078] The barrier panels 14 installed on both sides of the shuttle kiln body can effectively prevent accidental contact with the electrical components of the electric heating rod, and at the same time facilitate the upward flow of hot air in the kiln body, reducing the side temperature.

[0079] In addition, this embodiment also includes a shuttle kiln system, which includes an external conveying device and the shuttle kiln combined with the roller conveyor.

[0080] like Figure 3 and Figure 4 As shown, the external conveying device includes a movable carriage 15 and a second conveying roller module 16; the second conveying roller module 16 is mounted on the movable carriage 15 and has the same structure as the first conveying roller module.
