Embodiment 1

[0044] A composite grounding module, comprising a grounding module carrier 1 and a metal electrode 2 partially wrapped in the grounding module carrier 1, calculated by mass percentage, the grounding module carrier 1 is composed of 50% petroleum coke, 35% coal tar pitch coke, graphite 15% %composition. Such as figure 1 As shown, the grounding module carrier 1 is in the shape of a cuboid, and its length, width and height are 550mm, 110mm and 50mm respectively, and the metal electrode 2 is arranged at one end of the grounding module carrier 1 in the length direction.

[0045] A preparation method of a composite grounding module, comprising the following steps:

[0046] 1) Batching: batching the grounding module carrier 1 according to the composition of claim 1;

[0047] 2) Grinding: the raw materials are crushed and ground to make the particle size reach 0.075-0.7mm;

[0048] 3) Kneading: Put the milled raw materials into a kneading tank, add a certain amount of water, stir fo...

Embodiment 2

[0058] A composite grounding module, comprising a grounding module carrier 1 and a metal electrode 2 partially wrapped in the grounding module carrier 1, calculated by mass percentage, the grounding module carrier 1 is composed of 50% petroleum coke, 35% coal tar pitch coke, graphite 15% %composition.

[0059] Such as Figure 4 As shown, the grounding module carrier 1 is in the shape of a cuboid, and its length, width and height are 550mm, 130mm and 50mm respectively. The metal electrode 2 is arranged at one end of the length direction of the grounding module carrier 1, and the other end of the The centralized ion chamber 3 inside the grounding module carrier 1, wherein the centralized ion chamber 3 can be made by machining or mold opening, wherein the number of the centralized ion chamber 3 is two, and the centralized ion chamber 3 is filled with a drag reducing agent .

[0060] The grounding module is to add two centralized ion chambers 3 to the grounding module in embodim...

Embodiment 3

[0062] A composite grounding module, comprising a grounding module carrier 1 and a metal electrode 2 partially wrapped in the grounding module carrier 1, calculated by mass percentage, the grounding module carrier 1 is composed of 50% petroleum coke, 35% coal tar pitch coke, graphite 15% %composition.

[0063] Such as Figure 6 As shown, the grounding module carrier 1 is in the shape of a cuboid, and its length, width and height are 550mm, 200mm and 50mm respectively. The metal electrode 2 is arranged at one end of the length direction of the grounding module carrier 1, and the other end of the The centralized ion chamber 3 inside the grounding module carrier 1, wherein the centralized ion chamber 3 can be made by machining or mold opening, wherein the number of the centralized ion chamber 3 is three, and the centralized ion chamber 3 is filled with a drag reducing agent .

[0064] This grounding module is based on the grounding module of Embodiment 2, increasing the number ...
