Detailed implementation manners

[0029] Hereinafter, the technical solutions of the present application will be clearly and completely described in conjunction with the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope 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 will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0031] Please refer to Figure 1 , Figure 1 which is the schematic diagram of the principle of the water cooling circulation system 400 according to an embodiment of the present application. Figure 1 The arrow direction in

[0032] An embodiment of the present application provides a water cooling circulation system 400. The water cooling circulation system 400 includes: a first water machine 20 and two pressing plate water tanks 30. The first water machine 20 and the two pressing plate water tanks 30 together form a first circulation loop.

[0033] The first water machine 20 has a heat exchange function and can drive the refrigerant in the first circulation loop to circulate. It can be understood that: the first water machine 20 includes a circulation pump and a heat exchanger connected to each other, and the refrigerant can be cooling water. The pressing plate water tank 30 is arranged closely to the pressing plate unit 210 (see Figure 4) When the cooling water flows through the platen water tank 30, it exchanges heat with the platen unit 210, thereby being able to reduce the temperature of the platen unit 210 and extend the service life of the platen unit 210.

[0034] Among them, there may be only one, three, four or other numbers of platen water tanks 30, which are not specifically limited by this embodiment.

[0035] Specifically, the first circulation loop includes: a first branch 12, a second branch 13 and a first loop 14. The first branch 12 and the second branch 13 are arranged in parallel with each other. The water inlet end of the first loop 14 is respectively connected to the first branch 12 and the second branch 13, and the water outlet end of the first loop 14 is connected to the water inlet end of the first water machine 20.

[0036] A platen water tank 30 is provided on both the first branch 12 and the second branch 13. The cooling water first enters the first water machine 20, then leaves the first water machine 20 and enters the platen water tanks 30 of the first branch 12 and the second branch 13. After exchanging heat with the platen unit 210, it returns to the first water machine 20 through the first loop 14 again. The first water machine 20 cools the cooling water that returns again.

[0037] By arranging two platen water tanks 30 on the first branch 12 and the second branch 13 that are arranged in parallel respectively, multiple water tank copper plates can be accommodated in the same circulation loop and share the first water machine 20, which can improve the utilization rate of the cooling water. Moreover, the cooling effects of the cooling water in the two branches do not interfere with each other, and the work is stable and reliable.

[0038] Of course, in this embodiment, only two branches are used for illustrative purposes only, and the number of branches can be adjusted according to the actual scenario and is not specifically limited by this embodiment.

[0039] Optionally, the first branch 12 and the second branch 13 are water-cooled cables. The water-cooled cable can not only conduct electricity but also play a cooling role while conducting electricity.

[0040] In the case of excessive heat or insufficient refrigeration power of the first water machine 20, the temperature of the cooling water in the first circulation loop is too high. The too high water temperature will greatly reduce the heat exchange effect of the cooling water. Therefore, the water-cooled circulation system 400 of this embodiment further includes: a total water inlet pipe 10 and a total water outlet pipe. The output end of the total water inlet pipe 10 is connected to the input end of the first water machine 20 through the main path 11, and a second loop 15 is connected between the output end of the first water machine 20 and the total water outlet pipe.

[0041] When the cooling water is overheated, it can be controlled that the cooling water leaves the first circulation loop through the second loop 15, thereby reducing the working load of the first water machine 20 and improving the cooling effect of the first water machine 20.

[0042] Optionally, a thermometer is provided in the first circulation loop. The temperature of the cooling water can be measured by the thermometer, and a control valve is provided on the second loop 15. When the temperature exceeds a preset threshold, the control valve is controlled to open, and the cooling water leaves the first circulation loop from the second loop 15.

[0043] The water-cooled circulation system 400 further includes: a second water machine 41 and a first rectifier cabinet 42. The second water machine 41 and the first rectifier cabinet 42 together form the second loop 15.

[0044] The second water machine 41 has a heat exchange function and can drive the refrigerant in the second loop 15 to circulate. After the second water machine 41 drives the cooling water away, it exchanges heat with the first rectifier cabinet 42, thereby reducing the temperature of the first rectifier cabinet 42 and improving the service life of the first rectifier cabinet 42. Among them, the interior of the first rectifier forms a flow channel isolated from the outside to avoid leakage of the cooling water, and it is safe and reliable to use.

[0045] A third branch 16 is connected between the first rectifier cabinet 42 and the total outlet pipe. When the cooling water in the second loop 15 is overheated, the cooling water leaves the second loop 15 through the third branch 16, thereby reducing the load of the second water machine 41 and enhancing the cooling effect of the second water machine 41.

[0046] The water-cooled circulation system 400 further includes: a third water machine 51 and a second rectifier cabinet 52. The third water machine 51 and the second rectifier cabinet 52 form a third circulation loop.

[0047] The third water machine 51 has a heat exchange function and can drive the refrigerant in the third circulation loop to circulate. After the third water machine 51 drives the cooling water away, it exchanges heat with the second rectifier cabinet 52, thereby reducing the temperature of the first rectifier cabinet 42 and improving the service life of the first rectifier cabinet 42. Among them, the interior of the second rectifier forms a flow channel isolated from the outside to avoid leakage of the cooling water, and it is safe and reliable to use.

[0048] A fourth branch 17 is connected between the second rectifier cabinet 52 and the total outlet pipe. When the cooling water in the third circulation loop is overheated, the cooling water leaves the third circulation loop through the fourth branch 17, thereby reducing the load of the third water machine 51 and enhancing the cooling effect of the third water machine 51.

[0049] Among them, the first circulation loop, the second circulation loop and the third circulation loop are independently arranged. That is, the first circulation loop, the second circulation loop and the third circulation loop share the total inlet pipe 10 and the total outlet pipe. However, the cooling water in the three circulation loops does not communicate with each other. Even if the temperature of one of the circulation loops is abnormal, it will not affect the temperature of the other two circulation loops, and the water-cooled circulation system 400 works stably and reliably.

[0050] Please refer to Figures 2 to 5, in an embodiment of the present application, a power supply vehicle is provided, which is used to supply power to a graphitization furnace 500. Conductive electrodes are provided on both end walls of the graphitization furnace 500.

[0051] The power supply vehicle includes: a vehicle body 100, a power supply mechanism 300, a pushing mechanism 200, and the water-cooling circulation system 400 in any of the above embodiments. The power supply mechanism 300 and the pushing mechanism 200 are arranged on the vehicle body 100.

[0052] In the power supply vehicle of this embodiment, by setting the above-mentioned water-cooling circulation system 400, the water-cooling circulation system 400 forms a first circulation loop with the pressing plate water tank 30 and the water mechanism, and makes the pressing plate water tank 30 closely attached to the pressing plate unit 210. The cooling water circulates in the first circulation loop, and exchanges heat with the pressing plate unit 210 when flowing to the pressing plate water tank 30, so that the service life of the pressing plate unit 210 is long.

[0053] The power supply mechanism includes: a power-taking device, a rectifier transformer 310, and an electric short network. The rectifier transformer 310 is respectively connected to the power-taking device and the rectifier transformer 310. The rectifier transformer 310 includes a transformer body, a first rectifier cabinet 42, and a second rectifier cabinet 52. After the power-taking device takes power, it is transmitted to the transformer. After the power is converted into the type required by the graphitization furnace 500 via the transformer, it is then transmitted to the graphitization furnace 500 by the electric short network.

[0054] The pushing mechanism 200 includes: an oil cylinder mounting frame 230, a pushing oil cylinder 220, and a pressing plate unit 210. The pushing oil cylinder 220 is installed on the oil cylinder mounting frame 230. The pressing plate water tank 30 is arranged on the back side of the pressing plate unit 210, and the output shaft of the driving oil cylinder is connected to the pressing plate water tank 30. Among them, the back side of the pressing plate unit 210 is the side of the pressing plate unit 210 away from the conductive electrode.

[0055] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill 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 enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present application.
