Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a plug-in type graphite heater. Background Art

[0002] Graphite heaters are widely used in high temperature heat treatment systems of vacuum furnaces, as shown in the attached manual. Figure 1 As shown, the main connection methods currently rely on graphite nuts and graphite screws for connection and tightening to achieve close contact and obtain a conductive path.

[0003] In the process of implementing this solution, the inventors found that the following problems existed in the prior art and have not been well solved: in actual use, the breakage of the graphite nut and the graphite screw will cause the heaters to separate, and then arc burning will occur. Therefore, after each furnace production, the connection tightness of the graphite screw and the graphite nut must be checked, which is time-consuming and labor-intensive, and cannot completely avoid the fastening failure during the production process. Utility Model Content

[0004] The main purpose of the utility model is to provide a plug-in graphite heater, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A plug-in graphite heater comprises a heating plate A, wherein the top side walls of the heating plates A and B in the same direction are both provided with plugs, the top side walls of the heating plates A and B in the same direction are both provided with slots, and the plug on the heating plate A is inserted into the slot on the heating plate B.

[0007] Preferably, the outer dimensions of the plug match the inner dimensions of the slot.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] This technical solution achieves mutual fastening and close contact between heating plate A and heating plate B by designing a mortise and tenon type plug-in structure, thereby realizing a good conductive path. The plug-in structure can effectively ensure good contact between the heaters for a long time, thereby reducing equipment failures caused by arcing and burning due to heater detachment during the production process.
