[0022] The present application will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present application, but the embodiments are not intended to limit the present application.

[0023] Reference Figures 1 to 5 As shown, this application discloses a carbon roasting furnace cover plate, including: a cover body 1, multiple ceramic fiber modules 2 and multiple anchors 3. The cover body 1 includes a bottom frame 11 and four side frames 12. The four side frames 12 are fixedly connected to the four sides of the bottom frame 11. Multiple connecting rods 111 are arranged at intervals on the bottom frame 11. The multiple anchors 3 are respectively connected to the multiple connecting rods 111. The multiple ceramic fiber modules 2 are respectively inserted into the multiple anchors 3. The four side frames 12 surround the outer periphery of the multiple ceramic fiber modules 2.

[0024] Specifically, in this embodiment, the bottom frame 11 and the four side frames 12 are all welded from steel bars. In this embodiment, at least one connecting rod 111 is provided at the bottom frame 11 position corresponding to each ceramic fiber module 2, and at least one anchor 3 is connected to each connecting rod 111, so that each ceramic fiber module 2 can be inserted with at least one anchor 3 to ensure the stability of the connection between the ceramic fiber module 2 and the cover 1.

[0025] By setting up a cover body 1, multiple ceramic fiber modules 2, and multiple anchors 3, the bottom frame 11 of the cover body 1 is connected to four side frames 12. Multiple ceramic fiber modules 2 are installed in the cover body 1 by inserting them into the multiple anchors 3. Compared with the cover plates made of refractory bricks or castables in the prior art, the cover plate of this application significantly reduces its own weight, making it easier to open and close. The cover plate is simple to manufacture and easy to construct. Moreover, the ceramic fiber modules 2 used in this application have low heat storage and excellent thermal insulation performance, which reduces the heat energy consumption in the carbon calcining furnace and improves the thermal insulation effect.

[0026] In this embodiment, preferably, two horizontal bars 121 are arranged vertically and vertically on both sides of the frame 12; the carbon roasting furnace cover plate also includes multiple sets of first limiting components 4, each set of first limiting components 4 includes two sets of limiting parts 41, the two sets of limiting parts 41 are arranged symmetrically; each set of limiting parts 41 includes a moving block 411, a baffle 412, a baffle rod 413 and a fixing member 414, the moving block 411 is connected to one end of the baffle rod 413, the baffle 412 is disposed on the baffle rod 413, the other end of the baffle rod 413 passes through the two horizontal bars 121 and extends to the space between the two ceramic fiber modules 2, the baffle 412 is connected to the horizontal bar 121 through the fixing member 414, the width of the baffle 412 is smaller than the distance between the two horizontal bars 121, the moving block 411 is located outside the two horizontal bars 121, and the baffle 412 is located inside the two horizontal bars 121.

[0027] Specifically, in this embodiment, the number of sets of the first limiting component 4 is one less than the number of ceramic fiber modules 2.

[0028] In a specific implementation, after the first ceramic fiber module 2 is installed inside the cover 1, the movable block 411 in the first set of first limiting components 4 is placed outside the two crossbars 121. The baffle 412 is connected to the inside of the crossbar 121 through the fixing member 414. The baffle 413 passes through the two crossbars 121 and extends to the outside of the first ceramic fiber module 2. The second ceramic fiber module 2 is inserted into the anchor 3 after being close to the baffle 413, and then installed in the cover 1. Subsequently, the second set of first limiting components 4 is placed outside the second ceramic fiber module 2, and then the third ceramic fiber module 2 is installed, until all ceramic fiber modules 2 are installed in the cover 1.

[0029] By setting multiple sets of first limiting components 4, each ceramic fiber module 2 can be limited within the corresponding area of ​​the cover 1, avoiding the situation where the installation position of multiple ceramic fiber modules 2 is inaccurate when they are installed into the cover 1 due to the deformation of multiple ceramic fiber modules 2, thus improving the convenience of installing multiple ceramic fiber modules 2.

[0030] In this embodiment, preferably, the fastener 414 includes a slot 4141 and a block 4142. The slot 4141 is formed on the crossbar 121, and the block 4142 is connected to the baffle 412. The slot 4141 and the block 4142 are engaged.

[0031] Specifically, this application does not limit the number of slots 4141 and blocks 4142. In this embodiment, slots 4141 are provided on both crossbars 121, and two blocks 4142 are provided on each baffle 412.

[0032] By setting a slot 4141 on the crossbar 121 and a block 4142 on the baffle 412, the first limiting component 4 can be locked with the crossbar 121 and not move, thereby achieving the function of limiting the ceramic fiber module 2.

[0033] It should be noted that after all the ceramic fiber modules 2 are installed on the cover 1, the first limiting component 4 needs to be removed. Specifically, the moving block 411 is pressed along the inside of the cover 1, so that the locking block 4142 on the baffle 412 is disengaged from the slot 4141. Then the moving block 411 is rotated, which in turn drives the baffle 412 and the stop bar 413 to rotate. After the moving block 411 rotates, it is pulled away along the outside of the cover 1. Since the width of the baffle 412 is less than the distance between the two crossbars 121, the baffle 412 and the stop bar 413 can be removed from between the two ceramic fiber modules 2, thereby completing the disassembly of the first limiting component 4.

[0034] In this embodiment, preferably, each group of first limiting components 4 further includes a partition plate 42, and the other end of each of the two stop rods 413 is provided with a groove, and the partition plate 42 is inserted into the two grooves.

[0035] By setting a partition 42 between the two stop bars 413, the deformation of the ceramic fiber module 2 can be further restricted, and the limiting effect on the ceramic fiber module 2 can be improved.

[0036] It should be noted that before disassembling the limiting part 41 of the first limiting component 4, the operator should first remove the partition 42 from between the two ceramic fiber modules 2, and then disassemble the limiting part 41.

[0037] In this embodiment, preferably, multiple nuts 5 are connected to multiple connecting rods 111 of the bottom frame 11, and multiple anchors 3 are detachably connected to the bottom frame 11 through multiple nuts 5.

[0038] Specifically, the connection between nut 5 and connecting rod 111 is welded.

[0039] By setting a nut 5 on the connecting rod 111, the anchor 3 and the connecting rod 111 can be detachably connected. When it is necessary to replace the anchor 3 or the ceramic fiber module 2, the anchor 3 can be removed and replaced.

[0040] In this embodiment, preferably, each anchor 3 has a pointed end, and elastic claws 6 are provided on both sides of the pointed end.

[0041] By setting one end of the anchor 3 as a pointed tip, it can better pierce the ceramic fiber module 2 and thus be smoothly inserted into the ceramic fiber module 2; by setting elastic claws 6 on both sides of the pointed tip, the ceramic fiber module 2 can be further fixed and prevented from falling off.

[0042] In this embodiment, preferably, it also includes multiple sets of second limiting components 7. Each set of second limiting components 7 includes a fixing plate 71 and a bolt 72. The fixing plate 71 is connected to the connecting rod 111. The fixing plate 71 has a threaded hole. The other end of each anchor 3 is a flat end with a through hole. The bolt 72 passes through the threaded hole and the through hole.

[0043] In a specific implementation, after the anchor 3 is threadedly connected to the nut 5 on the connecting rod 111, the through hole on the flat end of the anchor 3 is positioned opposite to the threaded hole on the fixing plate 71. After the bolt 72 is threadedly connected to the threaded hole, it passes through the through hole and connects to the flat end of the anchor 3, thereby fixing the anchor 3.

[0044] By setting a fixing plate 71 and bolts 72 on the connecting rod 111, the anchor 3 can be fixed in a certain position and will not move, thus avoiding the anchor 3 being subjected to external forces and the nut 5 becoming loose during operation; by setting the other end of the anchor 3 to be flat, it is easier for the operator to clamp and rotate the anchor 3 when disassembling it.

[0045] In this embodiment, preferably, an observation hole 8 is formed on the ceramic fiber module 2 located at the center of the cover 1.

[0046] By setting up observation hole 8, the operator can observe the situation inside the carbon roasting furnace at any time.

[0047] The implementation principle of this application embodiment is as follows: After the operator installs the first ceramic fiber module 2 onto the cover 1 using the anchor 3, the first set of first limiting components 4 are installed on the outside of the first ceramic fiber module 2. The locking block 4142 on the baffle 412 engages with the locking groove 4141 on the crossbar 121 to limit the first ceramic fiber module 2. Then, the second ceramic fiber module 2 is installed. The operator continues to install the remaining ceramic fiber modules 2 in the above installation method. After all the ceramic fiber modules 2 are installed, the operator first removes the partition 42 from the multiple sets of first limiting components 4, and then removes the limiting part 41 from between two adjacent ceramic fiber modules 2, thereby completing the installation between the ceramic fiber module 2 and the cover 1.

[0048] In summary, by setting up a cover 1, multiple ceramic fiber modules 2, and multiple anchors 3, this application significantly reduces the weight of the cover 1 compared to the cover 1 of the prior art. The ceramic fiber modules 2 have low heat storage and excellent thermal insulation performance, thus improving the thermal insulation effect. By setting up a first limiting component 4, each ceramic fiber module 2 can be limited to the corresponding area of ​​the cover 1, avoiding the situation where a certain ceramic fiber module 2 is not accurately installed in the cover 1 due to deformation after installation, thereby improving the convenience of installing multiple ceramic fiber modules 2 in the cover 1.

[0049] 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 protection scope of this invention.
