[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] For easier understanding, see Figures 1 to 6 , the utility model provides an embodiment of a conductive electrode module, comprising an electrode rod 1 having a hollow interior and a cooling device;

[0036] The electrode rod 1 is made of stainless steel;

[0037] The top of the electrode rod 1 is sealed, a first drainage port 7 is provided at the bottom of the electrode rod 1, and a second drainage port 8 is provided at the bottom side of the side of the electrode rod 1. The first drainage port 7 and the second drainage port 8 are connected to the hollow interior of the electrode rod 1;

[0038] The cooling device includes a connecting water pipe 2 and a coolant. The connecting water pipe 2 is arranged in the hollow interior of the electrode rod 1. One end of the connecting water pipe 2 is connected to the first drainage port 7, and the other end of the connecting water pipe 2 is connected to the second drainage port 8. The interior of the connecting water pipe 2 is filled with coolant.

[0039] It should be noted that the coolant can be selected as water to reduce costs. The first drainage port 7 serves as the coolant outlet connected to the water pipe 2, and the second drainage port 8 serves as the coolant inlet connected to the water pipe 2. The electrode rod 1 is a cylindrical structure, which can improve the convenience of assembling the conductive electrode module to a certain extent, and can also be applied to the requirements and processes of the contact area between the graphite heating element and the conductive electrode. It is only necessary to change the outer diameter or height of the electrode rod 1 to simply achieve the increase or decrease of the contact area. Changing the material of the electrode rod 1 from pure copper to stainless steel solves the problem of limited pure copper resources and high costs. A cooling device is provided in the electrode rod 1, and the cooling device dissipates heat for the electrode rod 1, reduces the temperature of the electrode rod 1, and can effectively reduce the thermal deformation effect of the electrode rod 1. It solves the technical problem that the electrode body of the conventional heating device is made of pure copper material, which is costly and prone to high temperatures, causing thermal deformation of the electrode and affecting the service life.

[0040] In one embodiment, the conductive electrode module further includes a first conductive clamping plate 3 and a second conductive clamping plate 4, and the first conductive clamping plate 3 and the second conductive clamping plate 4 are respectively provided with grooves corresponding to the outer diameter of the electrode rod 1, and the first conductive clamping plate 3 and the second conductive clamping plate 4 are fixedly connected by bolts 6. The first conductive clamping plate 3 and the second conductive clamping plate 4 are mutually clamped to the outside of the electrode rod 1 by bolts 6, and the tightening force of the bolts 6 is converted into the clamping force of the first conductive clamping plate 3 and the second conductive clamping plate 4, and friction is generated with the surface of the electrode rod 1, so as to achieve the purpose of clamping. The first conductive clamping plate 3 and the second conductive clamping plate 4 are made of copper material. The outer surface of the electrode rod 1 is plated with hot-dip galvanizing of a preset thickness. The surface of the electrode rod 1 is plated with hot-dip galvanizing of a preset thickness, which can improve the arc lightning phenomenon when different conductive materials (the different conductive materials in this embodiment are the copper material of the first conductive clamping plate 3 and the second conductive clamping plate 4 and the stainless steel material of the electrode rod 1) are conductive. The preset thickness is 85um to 150um.

The circular notch surrounded by the first semicircular notch and the second semicircular notch can facilitate the coolant to flow out from the second drainage port 8. The cooling device also includes a water inlet pipe 10, a water outlet pipe 9, a cold water pump, a cooling water tank and a water outlet tank. The cold water pump is arranged in the cooling water tank, the water outlet of the cold water pump is connected to one end of the water inlet pipe 10, the other end of the water inlet pipe 10 is connected to the second drainage port 8, one end of the water outlet pipe 9 is connected to the water outlet tank, and the other end is connected to the first drainage port 7. Under the action of the cold water pump, the coolant in the cooling water tank flows from the water inlet pipe 10 through the connecting water pipe 2, the coolant in the connecting water pipe 2 dissipates heat and cools the electrode rod 1, and then flows into the water outlet pipe 9 through the first drainage port 7, and finally enters the water outlet tank. The cold water tank may also be provided with a water outlet interface, and the cooling water tank may be provided with a water inlet interface, the water outlet interface is connected to the inlet end of the spiral water cooling pipe, and the outlet section of the spiral water cooling pipe is connected to the water inlet interface of the cooling water tank. Thus, the coolant in the water outlet tank is cooled by the spiral cold water pipe and then returns to the cooling water tank, so as to realize the recycling of the coolant. In order to further improve the cooling effect of the spiral cold water pipe on the coolant, a cooler may be arranged in the spiral cold water pipe, and the cooler may be used to realize the rapid cooling of the coolant.

[0042] The utility model also provides a heating device, which includes any conductive electrode module in the utility model, and also includes a power connection plate, which is electrically connected to the first conductive clamping plate 3 or the second conductive clamping plate 4. Bolts 6 are used to fasten the power connection plate and the first conductive clamping plate 3 or the second conductive clamping plate 4. The outer side of the first conductive clamping plate 3 or the second conductive clamping plate 4 can be set as an epitaxial electrode contact surface 5, and the first conductive clamping plate 3 or the second conductive clamping plate 4 has a certain contact area with the power connection plate, and the size of the contact area determines the size of the external power supply current. Specifically, the heating device is an electromagnetic induction heating furnace or a resistance heating furnace.
