[0030] In order to better explain the present application and facilitate understanding, the present application is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 1 The orientation of is used as a reference. The position of the locking hoop 21 relative to the bottom bracket 22 is defined as "upper"; the position of the furnace core block 11 relative to the support frame 23 is defined as "inner".

[0031] As mentioned above, in the study of ceramic ovens, it was found that the ceramic oven cores available on the market are a whole and are simply made to fit the shape of the ceramic oven. Since the ceramic oven core needs to be in a carbon baking environment for a long time during use and works in a high temperature environment for a long time, the material repeatedly expands and contracts due to heat and cold, there is a great risk of breakage.

[0032] In order to solve at least one of the technical problems existing in the prior art or related art, the present application provides a split furnace core and a ceramic oven, the split furnace core comprising: a ceramic furnace core 1 and a furnace core seat 2, the ceramic furnace core 1 is arranged in the furnace core seat 2; the ceramic furnace core 1 is spliced ​​by a plurality of furnace core blocks 11, and each furnace core block 11 has the same structure. The furnace core seat 11 can be made of high-temperature resistant metal material, and the ceramic furnace core 1 is fixed by the furnace core seat 2 to form a furnace core as a whole. The splicing part of the ceramic furnace core 1 is equivalent to an expansion joint, which can effectively eliminate the stress caused by thermal expansion and contraction, thereby preventing the overall furnace core from breaking. The furnace core block 11 can be made of high-temperature resistant powdered material and placed in a steel mold for die casting. The finished product of the processed furnace core block 11 has high dimensional accuracy and small installation error. The structure of the furnace core block 11 is simple and easy to assemble, which can reduce production costs and after-sales service costs.

[0033] The split stove core and ceramic oven according to some embodiments provided by the present application are described below with reference to the accompanying drawings.

[0034] See also Figures 1 to 7 The present application provides a split furnace core in one embodiment, comprising: a ceramic furnace core 1 and a furnace core seat 2, wherein the ceramic furnace core 1 is arranged in the furnace core seat 2; the ceramic furnace core 1 is formed by splicing a plurality of furnace core blocks 11, and each furnace core block 11 has the same structure. Figure 1 As shown, the furnace core seat 2 is used to fix the ceramic furnace core 1. A charcoal pad or a charcoal basket can be placed in the ceramic furnace core 1 to hold coal. The ceramic furnace core 1 is composed of a plurality of furnace core blocks 11 spliced ​​together to form a furnace core as a whole. The splicing is equivalent to an expansion joint, which can effectively eliminate the stress caused by thermal expansion and contraction, thereby preventing the overall furnace core from breaking.

[0035] Furthermore, the number of core blocks 11 constituting the ceramic core 1 can be designed according to actual needs. For example, two core blocks 11 can be spliced ​​together to form a ceramic core 1; four core blocks 11 can be spliced ​​together to form a ceramic core 1; five core blocks 11 can be spliced ​​together to form a ceramic core 1; or nine core blocks 11 can be spliced ​​together to form a ceramic core 1.

[0036] Furthermore, the furnace core seat 2 can be made of high temperature resistant metal materials, such as stainless steel, copper, iron, aluminum, etc. The shape of the furnace core seat 2 can be designed according to the shape of the ceramic furnace core 1. For example, if the shape of the ceramic furnace core 1 is cylindrical, the shape of the furnace core seat 2 can be designed as a circular ring; if the shape of the ceramic furnace core 1 is a rectangular parallelepiped, the shape of the furnace core seat 2 can be designed as a long strip frame, etc.

[0037] Furthermore, the furnace core block 11 can be made of high temperature resistant powdered material placed in a steel mold for die casting, and the finished furnace core block after processing has high dimensional accuracy and small installation error. Since each furnace core block 11 has the same structure, only one mold is needed, the structure is simple, and it is easy to assemble, which can reduce production costs and after-sales service costs.

[0038] In an illustrative embodiment, Figure 2 and Figure 5 As shown, the furnace core seat 2 includes: a locking hoop 21, a bottom bracket 22 and a support frame 23. The support frame 23 is arranged between the locking hoop 21 and the bottom bracket 22, and the support frame 23 is connected to the locking hoop 21 and the bottom bracket 22 respectively; the ceramic furnace core 1 is arranged on the bottom bracket 22; the locking hoop 21 is provided with a locking mechanism, and the locking hoop 21 fixes the ceramic furnace core 1 through the locking mechanism. One end of the support frame 23 is connected to the locking hoop 21, and the other end is connected to the bottom bracket 22. The support frame 23 connects the locking hoop 21 and the bottom bracket 22 together to play a supporting role. The ceramic furnace core 1 is placed on the bottom bracket 22, and the locking mechanism can shrink the locking hoop 21. By locking the locking hoop 21, the ceramic furnace core 1 can be fixed, so that all the furnace core blocks 11 are spliced ​​to form a furnace core as a whole, and will not move.

[0039] Furthermore, the support frame 23 can be designed to be in the shape of a long strip, and the number of the support frames 23 can be set to be greater than or equal to 2, for example: 2, 3, 4, 5 or 6. The support frames 23 can be evenly distributed around the locking hoop 21 and the base 22; the support frames 23 can also be arranged in an uneven manner as required. It can be understood that the support frame 23 only plays a supporting role, so the support frame 23 can not only be designed in the shape of a long strip, but also can be designed in different shapes as required, such as letter shapes, heart shapes or wave shapes, etc., to play an aesthetic role.

[0040] In an illustrative embodiment, Figure 3 and Figure 5 As shown, the furnace core base 2 also includes: support legs 24, which are connected to the bottom bracket 22. The support legs 24 can provide stable support to help the furnace core base 2 maintain balance and stability; the length of the support legs 24 can be adjusted as needed to change the height of the furnace core base 2, so as to adapt to different ceramic ovens.

[0041] Furthermore, the support leg 24 can be detachably connected to the bottom bracket 22 by a second screw 28, and the second screw 28 can be an M6 stainless steel pan head screw. The support leg 24 can also be fixedly connected to the bottom bracket 22 by welding.

[0042] Furthermore, the number of the support legs 24 can be set to be greater than or equal to 2, for example: 2, 3, 4, 5 or 6, etc. The support legs 24 can be evenly distributed around the base 22; the support legs 24 can also be arranged in an uneven manner as needed. It is understandable that the support legs 24 can also be designed into different shapes as needed, such as foldable, adjustable or curved. The foldable support legs can be unfolded or folded as needed. This design provides flexibility and portability and can be conveniently used in different environments and scenarios; the adjustable support legs have retractable or rotatable parts, and the length or angle of the support legs can be adjusted as needed; the curved support legs have a soft curved profile, which is not only beautiful, but also can reduce stress concentration and provide better structural stability.

[0043] In an exemplary embodiment, the locking mechanism includes: a locking bolt 25 and a nut 27. The locking bolt 25 passes through a screw hole provided on the locking hoop 21 and the nut 27 to form a threaded locking method. The threaded locking method is very common in machinery and engineering. By rotating threaded parts, such as the locking bolt 25 and the nut 27, they are tightly fitted together to achieve a locking effect. The threaded locking method has the characteristics of simple structure and high reliability, and is widely used in various connection and fixing occasions.

[0044] Furthermore, the locking mechanism may also adopt an L-shaped locking structure, which is usually composed of a frame, a tightening rod, a locking rod, a stopper and a locking spring. The locking rod and the tightening rod are buckled together by the spring force to achieve the locking function. The L-shaped locking structure can be provided with different notches as needed to achieve different locking positions.

[0045] Furthermore, the locking mechanism can also adopt a rotary locking structure, in which the wrench member of the structure performs a circular motion, and the locking is achieved by the cooperation of the guide groove on the frame and the wrench pin, combined with the elastic force of the spring. The rotary locking structure has the characteristics of flexible operation and uniform locking force.

[0046] In an illustrative embodiment, Figure 6 and Figure 5 As shown, the core base 2 also includes: a first screw 26 and a nut 27, and the locking hoop 21 is detachably connected to the support frame 23 through the first screw 26 and the nut 27. The first screw 26 and the nut 27 are arranged in pairs, and the first screw 26 passes through the screw holes arranged on the locking hoop 21 and the support frame 23, and then the nut 27 is tightened, so that the locking hoop 21 and the support frame 23 can be tightly connected together. The first screw 26 can be an M6 stainless steel cross slot countersunk screw, and the nut 27 can be an M6 stainless steel hexagonal nut. The detachable connection method can facilitate the replacement of the locking hoop 21, which can reduce the cost of after-sales service.

[0047] Furthermore, the number of first screws 26 and nuts 27 can be set according to the number of support frames 23. For example, if the number of support frames 23 is 3, the number of first screws 26 and nuts 27 is also 3; if the number of support frames 23 is 5, the number of first screws 26 and nuts 27 is also 5.

[0048] In an illustrative embodiment, Figure 1 and Figure 4 As shown, a fixing groove 111 is provided on the core block 11, and a locking hoop 21 is arranged in the fixing groove 111. The locking hoop 21 is placed in the fixing groove 111, and after the locking hoop 21 is locked, all the core blocks 11 can be better fixed. The fixing groove 111 can also make it more convenient to install the core block 11 in the locking hoop 21.

[0049] In an illustrative embodiment, Figure 4 As shown, the core block 11 is provided with a support edge 112, and the support edge 112 is located on one side of the fixing groove 111. The support edge 112 is a raised portion, and one side of the fixing groove 111 where the support edge 112 is provided is wider than the other side. This is arranged to more conveniently install the core block 11 in the locking hoop 21, and the support edge 112 can also better prevent the locking hoop 21 from slipping off.

[0050] Furthermore, the support edge 112 can be disposed on a side of the fixing groove 111 close to the base 22 ; the support edge 112 can also be disposed on a side of the fixing groove 111 away from the base 22 .

[0051] In an illustrative embodiment, Figure 3 and Figure 4 As shown, the furnace core block 11 is provided with an inclined surface 113, which is located on both sides of the furnace core block 11. The two inclined surfaces 113 form a gap when two adjacent furnace core blocks 11 are spliced ​​together. The formed gap can effectively eliminate the stress caused by thermal expansion and contraction. At the same time, such a setting can also facilitate the replacement of the furnace core block 11, which can reduce the cost of after-sales service.

[0052] In an illustrative embodiment, Figure 6 and Figure 7 As shown, the furnace core block 11 is provided with chamfers 114, which are located around the furnace core block 11. Sharp corners can easily cause damage or wear to the furnace core block 11. By providing chamfers 114, the possibility of wear and damage can be reduced, the service life of the furnace core block 11 can be extended, and the durability of the furnace core block 11 can be improved.
