Description

Technical Field

[0001] This utility model relates to a kiln, and more particularly to a detachable roller kiln. Background Technology

[0002] When using kilns to produce products such as ceramic tiles, increasing the length of a single-layer kiln can increase output, but it requires more space. To save space, a single-layer roller kiln can be upgraded to a multi-layer roller kiln. However, due to the height restrictions of shipping containers, when the overall height of a prefabricated kiln exceeds 2550 mm, it cannot be packed and transported. Therefore, there is an urgent need to research a kiln structure that can both increase the internal height of the kiln and meet the requirements for container packing. Utility Model Content

[0003] The purpose of this utility model is to provide a detachable roller kiln to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A detachable roller kiln includes: a lower frame enclosing a kiln cavity with an upward opening, wherein a plurality of conveying roller groups are spaced apart in the lower frame along the vertical direction, and the plurality of conveying roller groups extend along the length direction of the lower frame; and an upper frame detachably connected to the top side of the lower frame, wherein the upper frame closes the opening of the kiln cavity.

[0006] This technical solution has at least the following beneficial effects: the lower frame can be pre-assembled at the factory, and multiple conveyor roller groups are spaced apart along the vertical direction inside the lower frame. These multiple conveyor roller groups are used to convey ceramic tile products along the length of the lower frame. The upper frame can be connected to the top side of the lower frame, forming a closed kiln cavity with the lower frame. When the kiln cavity is high, the upper frame and lower frame can be separated before leaving the factory, making it convenient to load and transport them separately. After being transported to the installation site, the upper frame can be reconnected to the lower frame. Since the multiple conveyor roller groups in the lower frame have been pre-assembled before leaving the factory, the time required for on-site assembly can be saved, and the efficiency of on-site assembly of the upper and lower frames can be improved. In this way, more products can be produced simultaneously by increasing the vertical height of the kiln, thereby improving the kiln's production efficiency. Furthermore, by separating the kiln vertically, the production, transportation, and installation of the kiln can be achieved, making the overall practicality stronger.

[0007] As a further improvement to the above technical solution, the lower frame is provided with lower connecting strips on both sides of its top along its width direction, and the upper frame is provided with upper connecting strips on both sides of its bottom along its width direction. The two upper connecting strips abut against the two lower connecting strips respectively, and multiple locking components are connected between the two upper connecting strips and the two lower connecting strips respectively.

[0008] As a further improvement to the above technical solution, the two lower connecting strips are tubular, and multiple nuts are respectively provided inside the two lower connecting strips. Multiple locking elements pass through the upper connecting strip and are threadedly connected to the nuts.

[0009] As a further improvement to the above technical solution, the number of conveying roller sets is two.

[0010] As a further improvement to the above technical solution, a partition layer is provided in the lower frame at the position between the two conveying roller groups.

[0011] As a further improvement to the above technical solution, pre-installed insulation layers are provided on both sides of the inner side of the lower frame and on the bottom side of the inner side of the lower frame.

[0012] As a further improvement to the above technical solution, post-installed insulation layers are respectively provided on both sides of the inner side of the upper frame and on the top side of the inner side of the upper frame, and the post-installed insulation layers on both sides of the inner side of the upper frame respectively abut against the pre-installed insulation layers on both sides of the inner side of the lower frame.

[0013] As a further improvement to the above technical solution, fixing plates are respectively connected to the two sides inside the upper frame, and the two fixing plates respectively press the post-installed insulation layer on the two sides inside the upper frame to the pre-installed insulation layer on the two sides inside the lower frame.

[0014] As a further improvement to the above technical solution, the pre-installed insulation layer and the post-installed insulation layer are both made of fire-resistant insulation materials.

[0015] As a further improvement to the above technical solution, the lower frame is provided with multiple support feet on its bottom side.

[0026] Reference Figures 1 to 3A detachable roller kiln includes a lower frame 100 and an upper frame 200. The lower frame 100 itself includes a base frame and first side frames connected to both sides of the base frame in the width direction. At this time, a kiln cavity with an upward opening is formed between the base frame and the two first side frames. Multiple conveying roller groups 110 are arranged at intervals in the vertical direction inside the lower frame 100, and the multiple conveying roller groups 110 extend along the length direction of the lower frame 100. The upper frame 200 is detachably connected to the top side of the lower frame 100. Naturally, the upper frame 200 also includes a top frame and second side frames connected to both sides of the top frame in the width direction. At this time, the two second side frames are detachably connected to the two first side frames respectively. The upper frame 200 closes the opening of the kiln cavity.

[0027] As described above, the lower frame 100 can be pre-installed at the factory. Multiple conveyor roller groups 110 are spaced apart along the vertical direction inside the lower frame 100. These multiple conveyor roller groups 110 are used to convey ceramic tile products along the length of the lower frame 100. The upper frame 200 can be connected to the top side of the lower frame 100, forming a closed kiln cavity with the lower frame 100. When the kiln cavity is high, the upper frame 200 and the lower frame 100 can be separated before leaving the factory for easy loading and transportation. After transportation to the installation site, the upper frame 200 can be reconnected to the lower frame 100. Since the multiple conveyor roller groups 110 inside the lower frame 100 are pre-installed before leaving the factory, the time required for on-site assembly can be saved, improving the efficiency of on-site assembly of the upper frame 200 and the lower frame 100. In this way, more products can be produced simultaneously by increasing the vertical height of the kiln, improving the kiln's production efficiency. Furthermore, by separating the kiln vertically, the production, transportation, and installation of the kiln can be achieved, making the overall practicality stronger.

[0028] In order to achieve a stable abutment and connection between the upper frame 200 and the lower frame 100, in this embodiment, the lower frame 100 is provided with lower connecting strips 120 on both sides of its width direction at the top, and the upper frame 200 is provided with upper connecting strips 210 on both sides of its width direction at the bottom. Naturally, both the upper connecting strips 210 and the lower connecting strips 120 extend along the length direction of the upper frame 200 or the lower frame 100. The two upper connecting strips 210 abut against the two lower connecting strips 120 respectively, and multiple locking elements 220 are connected between the two upper connecting strips 210 and the two lower connecting strips 120 respectively. When connecting the upper frame 200 and the lower frame 100, the lower connecting strips 120 on both sides of the top of the lower frame 100 abut against the upper connecting strips 210 on both sides of the bottom of the upper frame 200, so that the upper frame 200 and the lower frame 100 are stably abutted and positioned along their length. One upper connecting strip 210 and one lower connecting strip 120 facing each other form a connection group. In each connection group, multiple locking parts 220 are connected between the upper connecting strip 210 and the lower connecting strip 120. In this way, the upper frame 200 and the lower frame 100 can be firmly connected to each other, preventing them from shaking during operation.

[0029] The upper connecting strip 210 and the lower connecting strip 120 can have various structural forms, such as plate-shaped or tubular structures. In this embodiment, the two lower connecting strips 120 are tubular, and multiple nuts are respectively provided inside the two lower connecting strips 120. Multiple locking members 220 pass through the upper connecting strip 210 and are threadedly connected to the nuts. The tubular lower connecting strip 120 has higher structural strength and is not easily deformed under pressure. In this case, inserting multiple nuts into the lower connecting strip 120 can reduce the exposed connection structure, improve the overall appearance, and facilitate the connection and fixation of the upper connecting strip 210 and the lower connecting strip 120. When assembling the upper frame 200 and the lower frame 100, the locking member 220 passes through the upper connecting member and extends into the lower connecting member, and is threadedly connected and fixed to the nut, thereby locking the upper connecting strip 210 and the lower connecting strip 120 together. This allows for a stable and reliable assembly and disassembly of the upper frame 200 and the lower frame 100.

[0030] One conveyor roller group 110 can be used to convey one row of products. Theoretically, the more conveyor roller groups 110 there are, the more products the entire kiln can produce simultaneously. However, in actual production, due to limitations such as factory space and heat utilization, the number of conveyor roller groups 110 cannot be increased indefinitely. In this embodiment, there are two conveyor roller groups 110. During production, the two conveyor roller groups 110 are used to convey two rows of products such as ceramic tiles, respectively. At this time, two rows of products can be conveyed and produced simultaneously in the kiln cavity, improving the overall production efficiency.

[0031] To facilitate independent temperature control of the products produced by the two conveyor roller groups 110 within the lower frame 100, an independent temperature control structure can be installed inside the kiln. Specifically, a partition layer 150 is provided within the lower frame 100 between the two conveyor roller groups 110. Before leaving the factory, the partition layer 150 can be directly installed inside the lower frame 100 and connected to it as a whole for transport. During use, the partition layer 150 divides the lower kiln cavity into two independent spaces along the vertical direction. At this time, the two conveyor roller groups 110 are located in two independent spaces, which is beneficial for independently controlling the temperature of the products produced on the conveyor roller groups 110, improving production flexibility and quality.

[0032] To improve the thermal insulation capacity of the lower frame 100, in this embodiment, pre-installed insulation layers 130 are respectively provided on both sides and the bottom side of the lower frame 100. Before the lower frame 100 leaves the factory, a thermal insulation structure, namely the pre-installed insulation layer 130, is pre-installed inside the lower frame 100. During on-site assembly, it is not necessary to assemble the pre-installed insulation layer 130, thus improving the overall on-site assembly efficiency. The pre-installed insulation layer 130 effectively reduces heat loss, improving the efficiency and quality of kiln production.

[0033] Similarly, to reduce heat loss from the upper frame 200, in this embodiment, post-installed insulation layers 230 are respectively provided on both sides and the top side of the upper frame 200. The post-installed insulation layers 230 on both sides of the upper frame 200 abut against the pre-installed insulation layers 130 on both sides of the lower frame 100. At the factory, the upper frame 200 does not have an internal insulation structure, facilitating the assembly of the upper frame 200 and the lower frame 100. After connecting the upper frame 200 to the lower frame 100, an insulation structure, namely the post-installed insulation layers 230, is installed inside the upper frame 200. The post-installed insulation layers 230 on both sides of the upper frame 200 abut against the pre-installed insulation layers 130 on both sides of the lower frame 100, forming a continuous insulation structure on both sides of the kiln cavity. This further reduces heat loss and improves the efficiency and quality of kiln production.

[0034] To facilitate the installation and positioning of the post-installed insulation layer 230, in this embodiment, fixing plates 240 are respectively connected to the two sides of the interior of the upper frame 200. The two fixing plates 240 respectively press the post-installed insulation layer 230 on the two sides of the interior of the upper frame 200 against the pre-installed insulation layer 130 on the two sides of the interior of the lower frame 100. The two fixing plates 240 can form a structure for limiting and installing the post-installed insulation layer 230 on the two sides of the interior of the upper frame 200. After the upper frame 200 and the lower frame 100 are connected to each other, the two fixing plates 240 can respectively press the post-installed insulation layer 230 on the two sides of the interior of the upper frame 200 against the pre-installed insulation layer 130 on the two sides of the interior of the lower frame 100, so that a more continuous and stable insulation structure is formed on both sides of the kiln cavity.

[0035] In some embodiments, the pre-installed insulation layer 130 and the post-installed insulation layer 230 are both made of refractory insulation materials. This reduces the outward dissipation of hot air from the kiln cavity, improving heat utilization and production quality. In practical applications, the pre-installed insulation layer 130 within the lower frame 100 can have various structures. For example, on the inner bottom side of the lower frame 100, the pre-installed insulation layer 130 can be a layer of lightweight bricks, while on both sides inside the lower frame 100, it can be a partition formed by a combination of refractory insulation cotton, lightweight bricks, etc. Similarly, the pre-installed insulation layer 130 within the upper frame 200 can have various structures. For example, on the inner top side of the lower frame 100, it can be a partition formed by a combination of refractory insulation cotton, refractory insulation bricks, etc., or partitions formed by a combination of refractory insulation cotton, refractory insulation bricks, etc. can be provided on both sides inside the lower frame 100.

[0036] To facilitate stable support for the lower frame 100, in this embodiment, a plurality of support feet 140 are provided on the bottom side of the lower frame 100. The plurality of support feet 140 serve as support structures on the bottom side of the lower frame 100. In practical applications, the support feet 140 can be adjusted in height to further improve the stability of the lower frame 100 when supported.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
