Description

Technical Field

[0001] This utility model relates to the field of graphitization furnace technology, specifically a novel series-parallel switching rectifier device for graphitization furnaces. Background Technology

[0002] A graphitization furnace is a high-temperature processing device used for the sintering and graphitization of carbon materials. It is mainly used for high-temperature treatments such as sintering, graphitization, and purification of graphite powder. Operating temperatures can reach up to 3000℃, and it features high production efficiency, energy saving, and an online temperature measurement and control system that can monitor the furnace temperature in real time and automatically adjust it.

[0003] For example, the series-parallel switching switch and graphitization furnace rectifier system authorized by announcement number "CN221783100U" achieves the effect of frequently switching between parallel and series power supply methods during production by setting a first series-parallel switching switch and a second series-parallel switching switch between the graphitization furnace and the special transformer. This allows for multiple connection and disconnection of power supply, effectively overcoming the problems of complex operation and high failure rate of existing series-parallel switching switches, and ensuring the normal operation of series-parallel switching in the graphitization furnace rectifier system. However, this device is not convenient for quick replacement of the contact copper plates when using the equipment. The copper plates are subject to considerable wear during switching and need to be replaced periodically, making the device inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience caused by the inconvenience of replacing the device, and to propose a new series-parallel switching rectifier for graphitization furnaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel series-parallel switching rectifier for a graphitization furnace is designed, comprising bumps and copper plates. The inner walls of the bumps on both sides are symmetrically fixed with copper plates. The bumps have a switching structure inside and threaded holes are symmetrically opened on the surface of the bumps.

[0007] Preferably, the switching structure includes a rotating shaft and a rotating rod. The two ends of the rotating shaft are respectively inserted into the protrusions on both sides. The outer wall of the rotating shaft is movably connected to the rotating rod through a bearing. One end of the rotating rod is fixedly connected to a support plate. The outer wall of the support plate is fixedly connected to a cylinder. The inner wall of the cylinder is threaded. The outer wall of the cylinder is inserted into a copper sheet.

[0008] Preferably, one end of the copper sheet is attached to the rotating rod, and one end of the rotating rod is fixedly connected to the handle.

[0009] Preferably, the cylinder is threadedly connected to the first bolt through a through hole on its surface, and the protruding part of the first bolt abuts against the copper sheet.

[0010] Preferably, the upper ends of the protrusions on both sides are in contact with the horizontal plate, and the horizontal plate is threadedly connected to the protrusions by two second bolts.

[0011] This utility model proposes a novel series-parallel switching rectifier device for a graphitization furnace. Its advantages lie in the following: through the cooperation of the switching structure and the protrusions, after the copper sheet has been used for a period of time, the operator disconnects the power, rotates and removes the two second bolts on the surface of the horizontal plate, allowing the protrusions on both sides to separate. Simultaneously, the operator rotates and removes the first bolt, allowing the copper sheet to be removed. The operator can then replace the copper sheet. The device can then be reassembled and used after the above operations. This allows for quick replacement of the copper sheet, making the device more convenient to use. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figure 1-5In this embodiment, a novel series-parallel switching rectifier for a graphitization furnace includes protrusions 1 and copper plates 6. Copper plates 6 are symmetrically fixed to the inner walls of both protrusions 1. The copper plates 6 need to be connected to the control terminal of the graphitization furnace via wires. A switching structure 2 is provided inside the protrusions 1. Threaded holes are symmetrically opened on the surface of the protrusions 1. One end of the copper sheet 202 is in contact with the rotating rod 205. One end of the rotating rod 205 is fixedly connected to the handle 3. The cylinder 201 is threadedly connected to the first bolt 7 through a through hole on its surface. The protruding part of the first bolt 7 abuts against the copper sheet 202. An insulating gasket is provided between the first bolt 7 and the copper sheet 202. The upper ends of both protrusions 1 are in contact with the horizontal plate 4. The horizontal plate 4 is threadedly connected to the protrusions 1 via two second bolts 5.

[0020] The switching structure 2 includes a rotating shaft 204 and a rotating rod 205. The two ends of the rotating shaft 204 are respectively inserted into the protrusions 1 on both sides. The outer wall of the rotating shaft 204 is movably connected to the rotating rod 205 through a bearing. One end of the rotating rod 205 is fixedly connected to a support plate 203. The outer wall of the support plate 203 is fixedly connected to a cylinder 201. The inner wall of the cylinder 201 is threaded. The outer wall of the cylinder 201 is inserted into a copper sheet 202.

[0021] Working principle:

[0022] When the graphitization furnace is subjected to series-parallel switching control rectification:

[0023] This device is installed between the graphitization furnace and the special transformer. The copper plate 6 of this device is wired (the wiring method is consistent with the control switch of the existing technology), so as to realize the effect of switching between parallel and series power supply in production. The operator turns the lever 205 by the handle 3 to rotate the shaft 204, so that the lever 205 can drive the copper sheet 202 to rotate synchronously through the support plate 203. The copper sheet 202 can rotate in different directions, so that the copper sheet 202 can be attached to the copper plates 6 on both sides respectively to complete the series-parallel switching, and at the same time control the rectification.

[0024] Replacement process:

[0025] When the copper sheet 202 wears out after one end has been used for a period of time, the operator disconnects the power and removes the two second bolts 5 on the surface of the horizontal plate 4 by rotating them, so that the protrusions 1 on both sides can be separated. At the same time, the operator removes the first bolt 7 by rotating it, so that the copper sheet 202 can be removed. The operator can then replace the copper sheet 202 and reassemble it for use according to the above operation.

[0026] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
