DETAILED DESCRIPTION

[0029] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0030] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0031] The power transmission vehicle is a movable device for transmitting electricity to the graphitization furnace. The power transmission vehicle is provided with a power supply mechanism, one end of which is electrically connected to an external power source to obtain electricity, and the other end is connected to the graphitization furnace to transmit electricity to the graphitization furnace.

[0032] Usually, the graphitization furnace adopts intermittent single-furnace power supply, that is, one rectifier transformer supplies power to one graphitization furnace, and when one power supply cycle is completed, it supplies power to another graphitization furnace. In fact, intermittent single-furnace power supply has the problems of low utilization rate of rectifier transformers, high energy loss caused by complex short-circuit networks, and increased use costs.

[0033] Therefore, some manufacturers are currently trying to use a dual-furnace power supply method to supply power to the graphitization furnace, that is, using one power supply mechanism to supply power to two graphitization furnaces at the same time.

[0034] An embodiment of the present application provides a power transmission vehicle for implementing a dual-furnace power transmission method.

[0035] Among them, the graphitization furnace is a series-in-series graphitization furnace, which connects two linear furnaces in series and is configured in a U-shape so that the two end walls are located on the same side. In this way, one power transmission vehicle can be used to supply power to the series-connected graphitization furnace. Of course, the graphitization furnace can also be a linear furnace.

[0036] See also Figure 1 to Figure 5 The power transmission vehicle includes: a current-carrying trolley 100 and a pushing trolley 200 . The current-carrying trolley 100 is provided with a power supply mechanism 10 , and the pushing trolley 200 is provided with a first pushing mechanism 20 and a second pushing mechanism 30 .

[0037] The power supply mechanism 10 is electrically connected to the first pushing mechanism 20 and the second pushing mechanism 30. In the scenario of supplying power to the graphitization furnace, the first pushing mechanism 20 is connected to the conductive electrode of one graphitization furnace, and the second pushing mechanism 30 is used to connect to the conductive electrode of another graphitization furnace.

[0038] The power transmission vehicle of the present application electrically connects the power supply device to the first pushing mechanism 20 and the second pushing mechanism 30 respectively, so that the power supply device can simultaneously transmit power to the first pushing mechanism 20 and the second pushing mechanism 30. The first pushing mechanism 20 and the second pushing mechanism 30 are connected to the conductive electrodes of the graphitization furnace. In the first stage of the power transmission curve, the power supply mechanism 10 simultaneously transmits power to the two graphitization furnaces on average, the power loss of the graphitization furnace is small, and the use cost is low.

[0039] It should be additionally explained that: since the power transmission vehicle 100 is connected in series with the series-connected graphitization furnace, the two graphitization furnaces obtain the same amount of electricity, so that the quality of the products produced by the graphitization furnaces is consistent.

[0040] The current-carrying trolley 100 and the pushing trolley 200 can be used as a whole, for example, a connection structure is provided between the current-carrying trolley 100 and the pushing trolley 200. The two ends of the connection structure are connected to the current-carrying trolley 100 and the pushing trolley 200 respectively. In this way, the pushing device on the pushing trolley 200 and the power supply device on the current-carrying trolley 100 can remain relatively still, so as to improve the stability of power transmission by the power transmission vehicle. Of course, the current-carrying trolley 100 and the pushing trolley 200 can also adopt a split structure, and the current-carrying trolley 100 and the pushing trolley 200 can move relatively.

[0041] See also Figure 2The power supply mechanism 10 includes a power supply device 11, a rectifier transformer 12 and a short-circuit network 13. The rectifier transformer 12 is electrically connected to the power supply device 11 and to the short-circuit network 13.

[0042] An external cable 300 is provided above the power transmission vehicle, and the external cable 300 is provided with a conductive sheet. Optionally, the power extraction device 11 is provided with a lifting assembly, a clamping body, and a conductive wire, and the lifting mechanism is used to drive the clamping body to rise and fall. When the clamping body rises to contact the conductive sheet suspended on the external cable 300, the current on the external cable 300 is transmitted to the power extraction device 11.

[0043] The rectifier transformer 12 is disposed on the current-carrying trolley 100 , and is connected to the power taking device 11 through an external cable 300 to obtain electric energy from the power taking device 11 , and outputs the obtained electric energy to the short circuit network after voltage regulation.

[0044] Specifically, the rectifier transformer 12 includes: a transformer 121 and a first rectifier cabinet 122 and a second rectifier cabinet 123 disposed on both sides of the transformer 121. The short circuit network is connected to the first rectifier cabinet 122 and the second rectifier cabinet 123 respectively.

[0045] The first rectifier cabinet 122 and the second rectifier cabinet 123 are used to convert the alternating current output by the transformer 121 into direct current.

[0046] See also Figure 5 The short-circuit network 13 includes: a busbar 131, a jumper busbar 132, a branch busbar 133 and a guide busbar 134. The busbar 131 is connected to the output terminal of the transformer 121, and the guide busbar 134 is connected to the first rectifier cabinet 122 or the second rectifier cabinet 123. The jumper busbar 132 is connected to the busbar 131, the branch busbar 133 and the guide busbar 134 respectively.

[0047] In the dual-furnace power supply scenario, the short-circuit network 13 includes several groups of branch busbars 133, one group of branch busbars 133 is used to supply power to one graphitization furnace, and the other group of branch busbars 133 is used to supply power to the other graphitization furnace.

[0048] The number of branch busbars 133 can be set according to the specific furnace type. For example, the graphitization furnace is a series-connected graphitization furnace. The short circuit network 13 is provided with two branch busbars 133 for each graphitization furnace, one of which is used for current inflow and the other is used for current outflow.

[0049] Correspondingly, the first pushing mechanism 20 and the second pushing mechanism 30 are arranged according to the type of the graphitization furnace. When the graphitization furnace is a series-connected internal series furnace, the power transmission vehicle is respectively provided with two sets of the first pushing mechanism 20 and two sets of the second pushing mechanism 30.

[0050] See also Figure 3 and Figure 4 The first pushing mechanism 20 includes: a pushing cylinder 22, a pushing plate 21 and a frame 23, one end of the pushing cylinder 22 is used to contact the reaction wall, and the pushing plate 21 is arranged at the other end of the pushing cylinder 22; the pushing cylinder 22 is arranged on the frame 23.

[0051] The reaction wall is arranged between the rectifying trolley and the pushing trolley 200, and the pushing oil cylinder 22 can be configured as a double extension oil cylinder. During the power transmission process, one output shaft of the pushing oil cylinder 22 presses against the reaction wall, and the other output shaft drives the pressing plate to press against the conductive electrode of the graphitization furnace.

[0052] The push plate 21 is connected to the branch busbar 133 via a water-cooling cable, which can not only maintain the electrical connection between the two but also play a role in cooling.

[0053] Furthermore, the frame 23 includes: a plurality of longitudinal beams 231 and a plurality of transverse beams 232 , and two ends of the transverse beam 232 are respectively connected to two adjacent longitudinal beams 231 ; and the push cylinder 22 is arranged on the transverse beam 232 .

[0054] The crossbeam 232 provides installation positions at different heights for the push cylinder 22 , so that the push cylinder 22 and the conductive electrode of the graphitization furnace are at the same height, so as to facilitate the docking of the push cylinder 22 and the conductive electrode.

[0055] Please refer again Figure 1 , Figure 2 and Figure 6 In another embodiment of the present application, a graphitization system is provided, comprising: at least two graphitization furnaces 400 and a power transmission vehicle according to any of the above embodiments.

[0056] The power transmission vehicle is provided with a power supply mechanism 10, a first pushing mechanism 20 and a second pushing mechanism 30. The power supply device is connected to the first pushing mechanism 20 and the second pushing mechanism 30 respectively. The first pushing mechanism 20 is used to connect to the conductive electrode of one graphitization furnace, and the second pushing mechanism 30 is used to connect to the conductive electrode of another graphitization furnace.

[0057] The graphitization system of the present application is electrically connected to the first pushing mechanism 20 and the second pushing mechanism 30 respectively through the power supply device of the power supply vehicle, and the power supply device can synchronously supply power to the first pushing mechanism 20 and the second pushing mechanism 30. The first pushing mechanism 20 and the second pushing mechanism 30 are respectively connected to the conductive electrodes of the graphitization furnace, and the power supply mechanism 10 simultaneously supplies power to the two graphitization furnaces on average, so that the power loss of the graphitization furnace is small and the use cost is low.

[0058] Optionally, the graphitization furnace 400 is a serial graphitization furnace; the power transmission vehicle includes two first pushing mechanisms 20, and the two first pushing mechanisms 20 are respectively connected to the conductive electrodes at the two end walls of the graphitization furnace.

[0059] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom still fall within the scope of protection created by this application.
