Description

Technical Field

[0001] The utility model relates to the technical field of sintering furnaces, in particular to a copper electrode installation structure of a sintering furnace. Background Art

[0002] The electrode assembly is an important component of the sintering furnace, and the copper electrode 1 with good electrical conductivity is an indispensable part of the electrode assembly.

[0003] The copper electrode 1 in the conventional electrode assembly is as follows Figure 1 As shown, the upper connecting section 101 of the copper electrode 1 has a diameter of 60 mm and is used to be inserted into the motor mounting seat 01 of the furnace body and connected to the graphite electrode 02 in the furnace body. The lower connecting section 102 of the copper electrode 1 has a diameter of 50 mm and is used to be connected to the terminal board 03 outside the furnace body. A copper electrode flange 2 is arranged between the upper connecting section 101 and the lower connecting section 102 of the copper electrode 1. The outer diameter of the copper electrode flange 2 is 85 mm and the thickness is 16 mm. When in use, the external current is introduced in sequence along the terminal board 03, the copper electrode 1 and the graphite electrode 02. The existing copper electrode installation structure is as follows Figure 2 As shown, the copper electrode 1 is inserted into the electrode mounting seat 01 of the furnace body and connected to the graphite electrode 02, and the copper electrode flange 2 is clamped by the upper insulating flange 3 and the lower insulating flange 4, and then fixed by the pressure cover flange 5. A sealing ring 6 is provided between the upper end face of the upper insulating flange 3 and the furnace body, and between the upper end face of the copper electrode flange 2 and the lower end face of the upper insulating flange 3 for sealing. In addition, a dust cover 7 is also provided on the copper electrode flange 2.

[0004] In the above-mentioned existing copper electrode installation structure, the outer diameter of the copper electrode flange 2 is set to 85 mm, only considering the role of installing the sealing ring 6 and fixing the copper electrode 1. Since the position of the copper electrode flange 2 is the position of the maximum outer diameter of the copper electrode 1, when processing the copper electrode 1, the raw material cutting diameter needs to be above 85 mm. The outer diameter of the copper electrode flange 2 is too large, which will lead to a large workload of turning processing, and the price of copper scrap recycling is low, there is a large waste of raw materials and high processing costs.

[0005] It can be seen that how to redesign the copper electrode installation structure to reduce the maximum outer diameter of the copper electrode 1, thereby reducing the raw material cost and processing cost of the copper electrode 1, is a problem that needs to be solved urgently.

While ensuring that the copper electrode is firmly installed and the furnace body has good air tightness, it can save the amount of raw materials for the copper electrode, reduce the workload of copper electrode turning, and reduce production costs.

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 3As shown, this embodiment provides a copper electrode mounting structure for a sintering furnace, including a copper electrode 1 and a gland flange 2. A copper electrode flange 3 is arranged on the copper electrode 1. The outer diameter of the copper electrode flange 3 in this embodiment is preferably 70 mm. The gland flange 2 is used to fix the copper electrode 1 to the electrode mounting seat 01 of the furnace body. Specifically, one end of the copper electrode 1 is inserted into the electrode mounting seat 01 and connected to the graphite electrode 02 in the furnace body, and the other end passes through the gland flange 2 and is connected to the terminal board 03 outside the furnace body. The gland flange 2 can be connected to the electrode mounting seat 01 through 8 M20 nuts to fix the copper electrode 1 to the electrode mounting seat 01; it also includes an upper insulating flange 4, a lower insulating flange 5, a first sealing ring 6 and a second sealing ring 7. The upper insulating flange 4 and the lower insulating flange 5 can be sleeved on the copper electrode 1, wherein the upper insulating flange 4 can It is embedded in the end of the electrode mounting seat 01, and the upper end face of the upper insulating flange 4 is provided with a groove, the groove of the upper insulating flange 4 matches the copper electrode flange 3, the lower insulating flange 5 can be embedded in the flange hole of the pressure cover flange 2, and the first sealing ring 6 and the second sealing ring 7 are preferably O-rings; when the copper electrode 1 is fixed in the electrode mounting seat 01 through the pressure cover flange 2, the upper end face of the copper electrode flange 3 is clamped with the end of the electrode mounting seat 01, and the copper electrode flange 3 is embedded in the groove of the upper insulating flange 4, the first sealing ring 6 is arranged between the upper end face of the upper insulating flange 4 and the end of the electrode mounting seat 01, the second sealing ring 7 is arranged between the lower end face of the copper electrode flange 3 and the groove of the upper insulating flange 4, and the upper end face of the lower insulating flange 5 is abutted against the lower end face of the upper insulating flange 4 to compress the first sealing ring 6 and the second sealing ring 7. This embodiment can reduce the outer diameter of the copper electrode flange 3 from the conventional 85 mm to 70 mm while ensuring that the copper electrode 1 is firmly installed and the furnace body has good air tightness, thereby saving the raw material consumption of the copper electrode 1, reducing the workload of the copper electrode 1 turning process, and reducing the production cost.

[0028] In this embodiment, when the lower insulating flange 5 is embedded in the gland flange 2, the upper end face of the lower insulating flange 5 protrudes from the upper end face of the gland flange 2.

[0031] In this embodiment, the upper insulating flange 4 is made of PEEK; the lower insulating flange 5 and the insulating gasket 9 are both made of bakelite.

[0032] In this embodiment, the sintering furnace copper electrode mounting structure further includes an insulating sleeve 10 , which is preferably a boron nitride insulating sleeve. The copper electrode 1 can be inserted into the electrode mounting seat 01 through the insulating sleeve 10 .

[0035] In summary, the utility model has high installation versatility. By rationally utilizing the space between the electrode mounting seat 01 and the gland flange 2, the outer diameter of the copper electrode flange 3 is reduced while ensuring that the copper electrode 1 is firmly installed and the furnace body is well airtight, thereby reducing the cutting diameter of the raw material of the copper electrode 1, thereby achieving the purpose of saving raw material usage and reducing the workload of turning. In this embodiment, the outer diameter of the copper electrode flange 3 is reduced from 85mm to 70mm, and the weight of the raw material of the copper electrode 1 is reduced by 4.6kg. For a single sintering furnace, there are usually at least 6 electrode assemblies.
