Description

Technical Field

[0001] This application relates to the field of graphite plate preparation technology, specifically to a spliced ​​graphite assembly. Background Technology

[0002] Graphite induction heating refers to the flow of a large current through a heating coil wound into a ring or other shapes, typically made of copper tubing. This generates a strong magnetic flux with rapidly changing polarity within the coil. When a graphite heating element is placed inside the coil, the magnetic flux penetrates approximately 20mm into the surface of the heating element, creating resistance within the element in the opposite direction to the heating current, thus generating a large eddy current. Due to the resistance within the graphite heating element, significant Joule heating is produced, causing its temperature to rise rapidly. This radiant heat then heats the products inside the furnace.

[0003] Therefore, graphite components are highly favored by manufacturers in the production process of vacuum furnaces because graphite has good high-temperature strength and is readily available. Graphite has good electrical and thermal conductivity, as well as porosity and a low coefficient of thermal expansion, making it one of the most thermally shock resistant materials. Graphite has a low temperature coefficient of resistance and low thermal inertia, allowing for rapid heating and cooling. It has no special requirements in workpiece processing, making it well-suited for vacuum furnace heating elements. Graphite is a superior heating element for vacuum furnaces, possessing advantages such as high temperature resistance, non-deformation, impact resistance, large radiating area, good flexibility, and ease of processing and installation. However, to achieve high-efficiency production, modern vacuum furnaces often use large-sized blanks for large-scale production, resulting in a large amount of scrap material. This leads to material waste, higher manufacturing costs, greater processing difficulty, and a higher likelihood of defective products. Utility Model Content

[0004] The purpose of this application is to provide a modular graphite assembly to address the drawbacks of using large-format blank materials in the prior art to manufacture vacuum furnaces.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] This application discloses a modular graphite assembly, which includes...

[0007] A plurality of graphite plates are arranged to form a hollow graphite heating element, and the graphite plates are provided with mounting parts.

[0008] A graphite insert is provided, wherein the graphite insert is inserted into the mounting part of two adjacent graphite plates to fix the adjacent graphite plates together, wherein the cross sections of the adjacent graphite plates are matched.

[0009] In a further embodiment of this application, the graphite heating element is cylindrical.

[0010] In a further embodiment of this application, the mounting portion includes mating holes spaced apart at the ends of the graphite plates, and the graphite insert is plugged into and connected to adjacent mating holes on adjacent graphite plates.

[0011] In a further embodiment, the graphite insert includes a graphite connector, and a first fixing member and a second fixing member are fixed at intervals on one side of the graphite connector. The first fixing member and the second fixing member are respectively placed in adjacent mating holes on adjacent graphite plates.

[0012] In a further embodiment, two limiting grooves are provided at intervals on one side of the graphite plate. The two limiting grooves are located on opposite edges of one side of the graphite plate and are connected to the outside. The two docking holes and the two limiting grooves are provided in a one-to-one correspondence. The graphite connecting seat is fitted into the adjacent limiting groove.

[0013] In a further embodiment, the mating hole is arranged along the length direction of the graphite plate.

[0014] In a further embodiment, the mating hole is located on the centerline of the end of the graphite plate.

[0015] In a further embodiment of this application, the graphite plate comprises 4 to 8 pieces.

[0016] The beneficial effects of this application are as follows:

[0017] This application changes the traditional method of processing a single blank material. Instead, it uses multiple graphite plates and graphite inserts for assembly. Appropriate graphite plates are selected for assembly according to the actual product size requirements. Multiple graphite plates can be quickly and accurately assembled into the final product without generating a large amount of scrap material or wasting resources. At the same time, the processing difficulty is reduced, ensuring a high yield rate.

[0018] The mating holes are set in the limiting grooves on the graphite plates. In use, after the graphite insert fixes the two graphite plates, the graphite connector can be placed in the two mating limiting grooves. In actual production, the thickness of the limiting grooves is the same as the thickness of the graphite connector, which improves the aesthetics of the product to a certain extent.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0026] like Figure 1 and Figure 2 As shown, this embodiment discloses a spliced ​​graphite assembly, which includes several graphite plates 1 and graphite inserts 2. The graphite plates 1 form a hollow graphite heating element, and the graphite plates 1 are provided with mounting parts. The graphite inserts 2 are inserted into the mounting parts of two adjacent graphite plates 1 to fix the adjacent graphite plates 1. The cross-sections of the adjacent graphite plates 1 are matched. In this embodiment, the assembled graphite heating element is cylindrical. Each graphite plate 1 has a "tile" structure. The surface of the graphite plate 1 is smooth. The length of the graphite plate 1 after assembly is the height of the product. Typically, the graphite heating element (the graphite assembly generates heat in the energized coil) is assembled using six graphite plates 1 and graphite inserts 2. The cross-section of the graphite plate 1 is fan-shaped, and the arc angle of the graphite plate 1 is set at 60 degrees. The six graphite plates 1 satisfy a 360-degree enclosure. Depending on the actual situation, you can choose to assemble 4 or 8 graphite plates 1. It should be noted that the number of graphite plates 1 assembled is usually an even number.

[0027] In use, prepare the required number of graphite plates 1 to actually enclose the graphite assembly. Fix the mounting parts of two graphite plates 1 by using graphite inserts 2. Then, use graphite inserts 2 to install the remaining graphite plates 1 in sequence until all graphite plates 1 are spliced ​​into a cylindrical shape. In actual use, under the action of the energized coil, the graphite assembly itself will heat up, thereby heating the items that can be placed inside the cavity.

[0028] As attached Figures 3 to 5As shown, in this embodiment, the mounting part includes mating holes 13 spaced apart at the short side ends of the graphite plate 1. The graphite insert 2 is inserted into and connected to the mating holes 13 on adjacent graphite plates 1. The graphite insert 2 includes a graphite connector 21. A first fixing member 22 and a second fixing member 22 are fixed at intervals on one side of the graphite connector 21. In actual production, the first fixing member 22 and the second fixing member 22 use a columnar structure and can be integrally manufactured with the graphite connector 21. When in use, the first fixing member 22 and the second fixing member 22 are placed in the mating holes 13 on adjacent graphite plates 1 respectively. In simple terms, the first fixing member 22 is inserted into the mating hole 13 on one graphite plate 1, and the second fixing member 22 is inserted into the mating hole 13 on another graphite plate 1. When inserting, it is important to ensure that the orientation of the arc-shaped convex surface of the graphite plate 1 is consistent.

[0029] In a further embodiment, a plurality of slightly raised protrusions are provided on the outer side of the first fixing member 22 and the second fixing member 22. During installation, the protrusions can increase the friction of the first fixing member 22, the second fixing member 22 and the corresponding mating hole 13, thereby improving the structural strength of the final graphite assembly. The protrusions in the figure are omitted and not shown.

[0030] Based on the structural connection strength and the aesthetics of the graphite components, the designers incorporated two spaced-apart limiting grooves 12 on one side of the graphite plate 1. These grooves 12 are located on opposite edges of the graphite plate 1 and are open to the outside (one side of each limiting groove 12 has no sidewall). Taking one graphite plate 1 as an example, two mating holes 13 and two limiting grooves 12 are correspondingly arranged. The mating holes 13 are located at the bottom of the corresponding limiting groove 12. During assembly, adjacent limiting grooves 12 on adjacent graphite plates 1 align to form... The long limiting groove 12 is used to fit the graphite connector 21. The mating hole 13 is set along the length of the graphite plate 1. Normally, the length of the mating hole 13 is less than the length of the graphite plate 1, but in this embodiment, the mating hole 13 penetrates the graphite plate 1. This is to facilitate the disassembly and assembly of the graphite insert 2. The mating hole 13 is set on the centerline of the end of the graphite plate 1 to ensure that the thickness of the graphite plate 1 on the side of the mating hole 13 is equal, and to prevent the thickness on one side from being too thin, which would affect the strength of the graphite assembly.
