The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1 to 6 The present invention preferably provides the following technical solution: a graphite thermal field heater, comprising: a plurality of graphite plates 111; a first assembly module disposed between adjacent graphite plates 111 for forming a cylindrical graphite heating zone; and a second assembly module disposed on each graphite plate 111 for longitudinal extension of the cylindrical graphite heating zone to adapt to different furnace sizes.

[0025] The graphite heating zone created in this application is composed of several graphite plates 111 and a first assembly module between adjacent graphite plates 111, combined with... Figure 1 , 2 As shown, in order to accommodate different furnace sizes, this application also provides a second assembly module on a single graphite plate 111 to realize the assembly of the upper and lower graphite plates 111, combined with... Figure 6 As shown, this extends the heating area and ensures the heating effect;

[0026] This application uses several assembleable graphite plates 111 with a segmented structure, which facilitates transportation and installation, reduces the risk of damage to large-sized graphite parts, and only requires replacement of the damaged part when partial damage occurs, without the need for complete scrapping, thus saving replacement costs.

[0027] Furthermore, each first assembly module includes a slot 211 formed on one side near the bottom of the graphite plate 111, a graphite block 212 located on the other side of the graphite plate 111 and adapted to and locked in the slot 211; and fasteners provided on the graphite plate 111 to achieve mechanical fixation of adjacent graphite plates 111.

[0028] Combination Figure 1 , 2 As shown in Figure 5, the slots 211 and graphite blocks 212 between adjacent graphite plates 111 can be matched and can realize the pre-assembly process of adjacent graphite plates 111. Under the action of fasteners, the assembly of slots 211 and graphite blocks 212 is further reinforced, ensuring the stability and tightness of the assembly.

[0029] Furthermore, the fastener includes a through groove 411 formed near the bottom sidewall of the graphite plate 111, and a first threaded groove formed in the graphite plate 111 for communicating with the through groove 411 and the slot 211; a second threaded groove 413 is formed on the graphite block 212 that is engaged with the slot 211; and a graphite threaded connector 412 is also included, which is used for reinforcing the installation of the slot 211 and the graphite block 212 when the graphite threaded connector 412 passes through the first threaded groove and is threadedly connected to the second threaded groove 413.

[0030] according to Figure 1 , Figure 5 It can be seen that the fastener acts between the slot 211 where one graphite plate 111 is located and the graphite block 212 where the other graphite plate 111 is located. It is worth noting that the first threaded groove is opened on one of the graphite plates 111, while the second threaded groove 413 is opened on the graphite block 212 where the other graphite plate 111 is located. When the graphite threaded joint 412 passes through the first threaded groove and is threadedly connected to the second threaded groove 413, it is used for the reinforcement assembly of the slot 211 and the graphite block 212.

[0031] Furthermore, the second assembly module includes a graphite insert 311 fixed to the top of each graphite plate 111, with a screw hole 312 in the middle of the graphite insert 311; and an insertion hole 313 opened at the bottom of the graphite plate 111 and communicating with the first threaded groove, for assembling the upper and lower graphite plates 111.

[0032] Combination Figure 1 , 2 As shown, the insertion hole 313 of the upper graphite plate 111 can mate with the graphite post 311 of the lower graphite plate 111. Since the insertion hole 313 is connected to the first threaded groove of the upper graphite plate 111, when the graphite post 311 of the lower graphite plate 111 extends into the insertion hole 313 of the upper graphite plate 111, the connection... Figure 5 The screw hole 312 in the middle of the graphite insert 311 can mate with the first threaded groove. Therefore, when the graphite threaded joint 412 passes through the first threaded groove, the process can also pass through the screw hole 312, realizing the upper and lower assembly process of the graphite plate 111. Figure 6 As shown, this design enables the left and right assembly of adjacent graphite plates 111, as well as the top and bottom assembly of adjacent graphite plates 111, through a single operation.

[0033] The second assembly module of this application can utilize the structure and operation of the first assembly module to achieve simple assembly, with ingenious structure, simple and quick operation.

[0034] Furthermore, each graphite plate 111 has several first elongated grooves 112 formed thereon, combined with Figure 1 As shown, this design reduces the size of the device and improves portability while ensuring heating performance.

[0035] Furthermore, a second elongated groove 113 is also provided in the middle of the graphite plate 111, which is perpendicularly connected to the through groove 411, in combination with... Figure 1 , 2 As shown in Figure 3, the second long groove 113 here not only reduces the size of the device, but also expands the operating space of the graphite threaded joint 412.

[0036] Furthermore, graphite conductive adhesive is coated between adjacent graphite plates 111 and between the slot 211 and the graphite card block 212 to ensure conductivity.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Among these, there are various methods of detachable installation, such as using a combination of plug-in and snap-fit, or using bolt connections, etc.
