It can be seen that the furnace body 5 of the electric kiln of the present invention is formed by connecting and assembling the base module 1, the combination module and the cover module 3 in sequence, that is, the furnace body 5 of the electric kiln of the present invention is usually designed in a modular manner, and is assembled into multiple modules. Since the weight of the single module is greatly reduced, it is convenient for users to carry it. At the same time, the furnace chamber 50 of the furnace body 5 is formed by the inner cavities of multiple hollow furnace wall modules 2 that are connected end to end in sequence along the axial direction of the furnace body 5. In this way, the volume of the furnace chamber 50 can be adjusted by increasing or decreasing the number of furnace wall modules 2, so that users can assemble electric kilns of various volumes according to their needs, avoiding the integrated design of the furnace body 5 with only one furnace chamber 50 volume, which cannot meet the diverse needs of users for using electric kilns.

[0066] Reference Figure 3 - Figure 5 ,or Figure 6 - Figure 8The furnace wall module 2 includes a furnace wall shell 20, a plurality of furnace wall refractory layers 21, a furnace wall insulation layer 22 and a furnace wall outer shield 23. The furnace wall refractory layer 21 is arranged in the furnace wall shell 20, and the inner cavity of the furnace wall module 2 is formed by enclosing the plurality of furnace wall refractory layers 21; the furnace wall insulation layer 22 is arranged between the furnace wall refractory layer 21 and the furnace wall shell 20, and the furnace wall insulation layer 22 is arranged around the outer periphery of the furnace wall refractory layer 21, which is conducive to heat preservation of the temperature of the furnace wall refractory layer 21, thereby playing a heat preservation effect on the temperature in the furnace 50, and accelerating the firing efficiency of the ceramics in the furnace 50.

[0067] In this embodiment, the furnace wall insulation layer 22 is fixed to the furnace wall shell 20 by bolts, and the furnace wall refractory layer 21 is fixed to the furnace wall insulation layer 22; an internal furnace wall heat dissipation channel 24 is provided between the furnace wall insulation layer 22 and the furnace wall shell 20, which is beneficial to the heat dissipation of the furnace wall insulation layer 22; the furnace wall outer shield 23 is provided on the outside of the furnace wall shell 20, and the furnace wall outer shield 23 is connected to the furnace wall shell 20. The furnace wall outer shield 23 plays a role in protecting the furnace wall shell 20; in addition, an external furnace wall heat dissipation channel 25 communicating with the outside of the furnace body 5 is provided between the furnace wall outer shield 23 and the furnace wall shell 20, which is beneficial to the heat dissipation of the furnace wall shell 20.

[0068] Of course, in other embodiments, the furnace wall module 2 can also omit the above-mentioned furnace wall insulation layer 22, and directly connect multiple furnace wall refractory layers 21 to the furnace wall outer shell 20. In this way, an internal furnace wall heat dissipation channel 24 that communicates with the outside of the furnace body 5 is provided between the furnace wall refractory layer 21 and the furnace wall outer shell 20, which is beneficial to the heat dissipation of the furnace wall refractory layer 21.

[0069] It should be noted that, in one embodiment, the furnace wall outer shield completely covers the furnace wall shell 20. Fig.12 In another embodiment, the outer shield of the furnace wall is distributed on the left, middle and right sides of the furnace wall shell 20, as shown in FIG. Fig.13 As shown, that is, the left, middle and right positions of the outer wall of the furnace wall shell 20 are all wrapped with the furnace wall outer shield; the furnace wall outer shield can also wrap the four corners of the furnace wall shell 20, such as Fig.14 It can be seen that those skilled in the art can reasonably change the structure of the furnace wall outer shield, which should also fall within the protection scope of the utility model.

[0070] In this embodiment, refer to Figure 4 or Figure 7In the furnace wall module 2 closest to the base module 1, a furnace wall refractory layer 21 is laid at one end closest to the base 10, that is, in addition to the furnace wall refractory layer 21 arranged in the circumferential direction of the furnace wall module 2 closest to the base module 1, a furnace wall refractory layer 21 is also arranged at one end closest to the base 10. In addition, among the multiple furnace wall modules 2 of this embodiment, except for the furnace wall module 2 closest to the base module 1, the opposite ends of the other furnace wall modules 2 are open ends, that is, the other furnace wall modules 2 are only provided with the furnace wall refractory layer 21 in the circumferential direction, which is conducive to the inner cavities of the multiple furnace wall modules 2 being connected to each other.

[0071] Of course, the gap between the two adjacent furnace wall modules 2 is sealed by the flexible refractory wool 62, and the flexible refractory wool 62 can be fixed on one of the two adjacent furnace wall modules 2, referring to Figure 4 and Figure 7 The flexible refractory wool 62 is sealed and clamped in the refractory layer of two adjacent furnace wall modules 2. Figure 6 The connection between the furnace wall modules 2 is achieved through two adjacent furnace wall shells 20 , and the two adjacent furnace wall shells 20 are connected through a connecting piece 61 , thereby realizing the connection between two adjacent furnace wall modules 2 .

The temperature sensor 27 penetrates the furnace wall refractory layer 21 and the furnace wall insulation layer 22 of the furnace wall module 2 along the radial direction of the furnace wall module 2. The temperature sensor 27 can be fixed to the furnace wall shell 20 by bolts. The temperature sensor 27 is used to detect the temperature of the inner cavity of the furnace wall module 2, which is beneficial for real-time understanding of the firing status of the ceramics in the furnace chamber 50.

[0073] In this embodiment, refer to Figure 4 or Figure 7 The end of the furnace 50 close to the base module 1 is provided with an air inlet 501, which is used to allow the air outside the furnace body 5 to enter the furnace 50, so as to achieve the effect of combustion, which is beneficial to improve the firing effect of the ceramic in the furnace 50; the end of the furnace 50 close to the cover module 3 is provided with an exhaust port 502 connected to the outside of the furnace body 5, and the exhaust port 502 is detachably connected to the refractory cover 36, which is used to cover the exhaust port 502. The exhaust port 502 is used to facilitate the timely discharge of moisture generated by the product in the furnace 50 during the heating stage of the furnace 50, so as to improve the firing quality of the ceramic in the furnace 50.

[0074] In this embodiment, refer to Figure 4 or Figure 7The base module 1 includes a base 10, which is connected and fixed to the furnace wall shell 20 closest to the base module. A valve plate 11 that can move in the horizontal direction is provided on the base 10, and the valve plate 11 is used to close the air inlet 501. Figure 6 and Figure 7 , the end of the valve plate 11 facing away from the air inlet 501 can be moved to penetrate the furnace wall module 2 closest to the base 10. Of course, a fan is also provided on the base 10 at a position corresponding to the air inlet 501, and the fan is a mixed flow fan 13, which can be fixed to the base 10 by bolts. When an oxidation reaction is required during the firing of ceramics in the furnace 50, the exhaust port 502 is in a closed state, and the valve plate 11 is moved in a horizontal direction at the same time, so that the air inlet 501 is in an open state, so that the airflow outside the furnace body 5 will quickly enter the furnace 50 under the action of the mixed flow fan 13, so that the high-temperature air inside the furnace 50 can fully flow and mix evenly, thereby improving the uniformity of contact between the ceramic firing process and oxygen, thereby improving the firing effect of the ceramic in the furnace 50.

[0075] It should be noted that the valve plate 11 can be driven electrically or manually, which is not limited here. The valve plate 11 of this embodiment is driven manually.

[0076] In this embodiment, refer to Figure 4 or Figure 7 The cover module 3 includes a cover shell 30, a cover refractory layer 31, a cover insulation layer 32 and a cover outer protective cover 33. The cover shell 30 is connected to the furnace wall shell 20 of the furnace wall module 2 closest to the cover module 3. The cover insulation layer 32 is arranged in the cover shell 30. The cover insulation layer 32 is arranged around the outer periphery of the cover refractory layer 31, which is beneficial to the temperature of the cover refractory layer 31, thereby having an insulation effect on the temperature in the furnace 50 and accelerating the firing efficiency of the ceramic in the furnace 50; an inner heat dissipation channel 34 is provided between the cover shell 30 and the cover insulation layer 32, which is beneficial to the heat dissipation of the cover insulation layer 32.

[0077] In this embodiment, the cover insulation layer 32 is fixed to the cover outer shell 30 by bolts, and the cover refractory layer 31 is fixed to the cover insulation layer 32. The cover outer protective cover 33 is arranged on the outside of the cover outer shell 30. The cover outer protective cover 33 is connected to the cover outer shell 30 to protect the cover outer shell 30. In addition, an outer heat dissipation channel 35 of the cover that communicates with the outside of the furnace body 5 is provided between the cover outer protective cover 33 and the cover outer shell 30, which is beneficial to the heat dissipation of the cover outer shell 30.

[0078] Of course, in other embodiments, the cover module 3 can also omit the cover insulation layer 32 and directly connect the cover refractory layer 31 with the cover outer shell 30. In this way, a cover heat dissipation channel 34 communicating with the outside of the furnace body 5 is provided between the cover refractory layer 31 and the cover outer shell 30, which is beneficial to the heat dissipation of the cover refractory layer 31.

[0079] It should be noted that the configuration of the outer protective cover of the cover can be the same as the configuration of the outer protective cover of the furnace wall, which will not be described in detail here.

[0080] In this embodiment, refer to Figure 4 or Figure 7 The cover module 3 also includes the above-mentioned refractory cover 36. The exhaust port 502 passes through the cover refractory layer 31 and the cover insulation layer 32 in sequence along the axial direction of the cover module 3. The refractory cover 36 is snap-connected with the cover insulation layer 32 by means of a snap buckle, thereby achieving the purpose of detachable connection between the refractory cover 36 and the exhaust port 502.

[0081] Of course, in other embodiments, the refractory cover 36 may also be threadedly connected to the cover insulation layer 32 to achieve the purpose of detachable connection between the refractory cover 36 and the exhaust port 502, which is not limited here.

[0082] In this embodiment, a handle 37 is fixed on the outer protective cover of the cover body, which is convenient for the user to hold the handle 37 and open the cover body module 3 .

[0083] In this embodiment, refer to Figure 4 or Figure 7 The heat dissipation channels 24 in the furnace wall of the multiple furnace wall modules 2 and the heat dissipation channels 34 in the cover body are interconnected to form the first air insulation cavity 4 of the furnace body 5. One end of the first air insulation cavity 4 is in communication with the outside of the furnace body 5. Specifically, a heat dissipation port 300 is provided on the cover body shell 30. The first air insulation cavity 4 is in communication with the outside of the furnace body 5 through the heat dissipation port 300. A heat dissipation fan 12 is provided at the other end of the first air insulation cavity 4. Of course, the air inlet 501 of the heat dissipation fan 12 is in communication with the outside of the furnace body 5. The heat dissipation fan 12 is fixed on the furnace wall shell 20 or the base 10. When the heat dissipation fan 12 is working, it blows the cooling air outside the furnace body 5 into the first air insulation cavity 4. The air in the first air insulation cavity 4 is finally discharged from the heat dissipation port 300, so as to achieve the effect of cooling the furnace body 5.

[0084] In this embodiment, the cover outer heat dissipation channel 35 is interconnected with the furnace wall outer heat dissipation channels 25 of multiple furnace wall modules 2 to form a second air insulation cavity 40 of the furnace body 5, which can further improve the heat dissipation effect of the furnace body 5.

[0085] In this embodiment, the two relative ports of the furnace 50 are respectively covered by the base module 1 and the cover module 3; specifically, it can be understood that the two relative ports of the furnace 50 are the above-mentioned exhaust port 502 and air inlet 501, and it can be seen that the exhaust port 502 is covered by the refractory cover 36 of the cover module 3, and the air inlet 501 is covered by the valve plate 11 of the base module 1.

[0086] When the product to be fired needs to be placed in the furnace 50, the furnace 50 needs to be opened for placement. The cover module 3 of this embodiment is hinged with the furnace wall module 2 connected to it, so that the cover module 3 serves as a door to open the furnace 50, thereby facilitating users to place the product to be fired in the furnace 50.

[0087] Of course, in other embodiments, a charging port 26 communicating with the furnace 50 may be provided on at least one furnace wall module 2, and a flap 260 is hingedly connected to the furnace wall module 2 provided with the charging port 26, and the flap 260 is used to cover the charging port 26, so that the flap 260 serves as a door to open the furnace 50, such as Fig.32 or Fig.33 or Fig.34 or Fig.35 shown.

[0088] It can be seen that the door for opening the furnace 50 is not limited to the cover module 3, but can also be the flip cover 260. Therefore, for those skilled in the art, by reasonably changing the door structure for opening the furnace 50, it should also fall within the protection scope of the present utility model.

[0089] In this embodiment, refer to Figure 2 An automatic telescopic device 63 is provided between the cover module 3 and the furnace wall module 2 connected thereto. The automatic telescopic device 63 uses an electric push rod to drive the cover module 3 to open or close. Specifically, one end of the automatic telescopic device 63 is hinged to the furnace wall module 2 closest to the cover module 3, and the telescopic end of the automatic telescopic device 63 is hinged to the cover module 3.
