DETAILED DESCRIPTION

[0031] 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.

[0032] 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.

[0033] See also Figure 1 and Figure 2 In one embodiment of the present application, a platen cooling device is disclosed, comprising: a platen 11, a water tank 12, and the water tank 12 is close to the platen 11. A coolant flow path 121 is formed in the water tank 12, and the coolant flow path 121 is used to connect with an external pipeline (not shown), and a water cooler (not shown) and a driving pump (not shown) are provided in the external pipeline.

[0034] The driving pump is used to drive the refrigerant to flow between the water cooler and the water tank 12 .

[0035] The refrigerant flow path 121 has a water inlet 122 and a water outlet 123. The water inlet 122 is connected to a water cooler, and the water outlet 123 is connected to a driving pump. The refrigerant is cooling water.

[0036] The platen cooling device 100 of this embodiment is connected to the water cooler and the driving pump through the water cooling pipeline in the water tank 12. During the power transmission process, the platen 11 is directly in contact with the conductive electrode of the graphitization furnace. The temperature of the platen 11 is higher than that of the water tank 12, and the temperature of the water tank 12 is higher than that of the refrigerant. The heat is conducted from the platen 11 to the water tank 12, and then to the refrigerant flowing through the water tank 12, and finally driven by the refrigerant to the water cooler to reduce the temperature of the platen 11 and extend the service life of the platen 11.

[0037] See also Figure 2 , Figure 2 The middle arrow indicates the direction in which the refrigerant flows in the water tank 12. In a specific embodiment, the refrigerant flow path 121 is bent back and forth.

[0038] The refrigerant enters the refrigerant flow path 121 through the water inlet 122, exchanges heat with the water tank 12, and then leaves the water tank 12 through the water outlet 123. The water inlet 122 and the water outlet 123 are both provided on the same side wall of the water tank 12.

[0039] A plurality of partitions arranged up and down are provided in the water tank 12, and the partitions and the side walls of the water tank 12 form an opening for allowing the refrigerant to flow. In addition, two openings formed by two adjacent partitions are one close to one side wall of the water tank 12, and the other close to the other side wall of the water tank 12.

[0040] The refrigerant flow path 121 may also be S-shaped, W-shaped, or U-shaped. Of course, it may also be other irregular shapes that can increase the wiring length of the return flow path, all of which belong to the inventive concept of the present application.

[0041] By arranging the refrigerant flow path 121 in a curved reciprocating manner in the water tank 12, the length of the water cooling circulation loop in the water tank 12 can be increased, thereby improving the heat exchange effect of the refrigerant.

[0042] In a specific embodiment, a mounting flange 124 is provided through the water tank 12 , and the water tank 12 is connected to the pressing plate 11 via fasteners passing through the mounting flange 124 .

[0043] By fasteners passing through the mounting flange 124 and the pressure plate 11, the pressure plate 11 can be detachably connected to the water tank 12. When the pressure plate 11 is damaged by overheating, only the pressure plate 11 needs to be replaced, thereby reducing maintenance costs.

[0044] See also Figure 3 to Figure 5 In a specific embodiment, the platen cooling device 100 further includes a driving member 20, and an output shaft of the driving member 20 is connected to the platen assembly.

[0045] The driving member 20 may be a push cylinder, the output shaft of which is connected to the water tank 12, and the pressing plate 11 is driven to approach or move away from the conductive electrode of the graphitization furnace through the water tank 12. Specifically, when power is supplied, the push cylinder drives the water tank 12 to abut against the conductive electrode. When power is supplied, the push cylinder drives the water tank 12 to separate from the conductive electrode.

[0046] In a specific embodiment, an insulating plate 125 is provided between the water tank 12 and the output shaft of the driving member 20 .

[0047] The cross-sectional area of ​​the insulating plate 125 is configured to be much larger than the output shaft of the driving member 20 so as to increase the creepage distance between the driving member 20 and the water tank 12 , prevent overload breakdown, and improve the safety of the platen cooling device 100 .

[0048] In a specific embodiment, a push plate is provided at the free end of the output shaft of the driving member 20 , a force plate 1241 is provided on the side of the mounting flange 124 facing the push plate, the push plate is connected to the insulating plate 125 , and the insulating plate 125 is connected to the force plate 1241 .

[0049] The contact between the push plate and the force-bearing plate 1241 can increase the contact area between the water tank 12 and the driving member 20 to prevent the water tank 12 from being damaged due to excessive local pressure.

[0050] See also Figure 4 In a specific embodiment, a wheel set 126 is provided at the bottom of the water tank 12 .

[0051] The wheel set 126 can support the water tank 12 and can move along with the water tank 12 when the driving member 20 drives the water tank 12 to move.

[0052] See also Figure 4 and Figure 5 The platen cooling device 100 further includes a frame 30 , and the driving member 20 is installed on the frame 30 .

[0053] The driving member 20 is a push cylinder, and the cylinder body of the push cylinder is installed on the frame 30. Optionally, the platen cooling device 100 includes two frames 30 arranged in the front-to-back direction, and the installation direction and position of the driving member 20 are determined by the two frames 30, so as to ensure that the water tank 12 can accurately abut the conductive electrode of the graphitization furnace.

[0054] See also Figure 6 The frame 30 includes: a longitudinal beam 31, a cross beam 32 and a mounting bracket 33, the longitudinal beam 31 is connected to the cross beam 32, and the mounting bracket 33 is arranged on the cross beam 32; the driving member 20 is arranged on the mounting bracket 33.

[0055] In this embodiment, there are three longitudinal beams 31 arranged at intervals, and the adjacent longitudinal beams 31 are connected by two upper and lower cross beams 32. Each cross beam 32 is provided with a mounting bracket 33, and the mounting bracket 33 is used to fix the driving member 20 to the frame 30.

[0056] See also Figure 7 In one embodiment of the present application, a power transmission vehicle is disclosed, including: a vehicle body 200 and a pressure plate cooling device 100 of any of the above-mentioned embodiments arranged on the vehicle body 200.

[0057] The power transmission vehicle of this embodiment is provided with a platen cooling device 100, and the water tank 12 is connected to the water cooler and the driving pump through a water cooling pipeline. During the power transmission process, the platen 11 is directly in contact with the conductive electrode of the graphitization furnace, and the temperature of the platen 11 is higher than that of the water tank 12, and the temperature of the water tank 12 is higher than that of the refrigerant. The heat is conducted from the platen 11 to the water tank 12, and then to the refrigerant flowing through the water tank 12, and finally driven by the refrigerant to the water cooler, so as to reduce the temperature of the platen 11, extend the service life of the platen 11, and reduce the maintenance cost of the power transmission vehicle.

[0058] The power transmission vehicle may include two vehicle bodies 200, and each vehicle body 200 is provided with two pressure plate cooling devices 100. A connecting rod is provided between the two vehicle bodies 200 to ensure that one vehicle body 200 drives the other vehicle body 200 to move.
