Description

Technical Field

[0001] The utility model provides an electrode sleeve structure for high-temperature purification equipment, belonging to the technical field of carbon-based material production equipment. Background Art

[0002] When high-temperature purification equipment is in operation, its internal temperature can reach 2300°C. Currently known insulating parts cannot withstand temperatures of 2300°C. Therefore, high-temperature purification equipment adopts vacuum insulation, that is, a circular hole larger than the diameter of the graphite electrode is opened on the insulation felt. The gap between the graphite electrode and the insulation felt serves as insulation.

[0003] At present, when manufacturing high-temperature purification equipment, in order to prevent the insulation felt from being deformed by high temperature and affecting the insulation gap and reducing the insulation effect, a graphite sleeve is added between the insulation felt and the graphite electrode. This can ensure that the insulation gap will not be affected when the insulation felt is deformed. However, when the graphite electrode is installed on the inclined surface of the insulation felt, it is necessary to install angled insulation felt (upper insulation felt and lower insulation felt) on the inclined surface of the insulation felt, and then install the graphite sleeve from the bottom of the electrode hole after leveling the inclined surface. The lower insulation felt is pressed down by the graphite sleeve, and the upper insulation felt is tightened by screwing it to the electrode sleeve through the electrode sleeve nut. That is, the traditional graphite electrode sleeve assembly for installation on the inclined surface of the insulation felt consists of four parts: the electrode sleeve, the lower insulation felt, the upper insulation felt and the electrode sleeve nut. Figures 1 to 3 This setup causes the insulation felt to wrap around the copper electrode, causing localized high temperatures at the bottom of the copper electrode. Even with the protection of the graphite sleeve, the copper electrode will melt at this high temperature, necessitating the use of very low-temperature cooling water to maintain normal operation. This structural setup, over long periods of operation, can shorten the lifespan of the copper electrode and increase energy consumption. If the copper electrode is damaged during operation, the cooling water inside the copper electrode can enter the furnace of the high-temperature purification equipment, causing a safety accident. Utility Model Content

[0004] In order to solve the technical problem that when the graphite electrode is installed on the inclined surface of the insulation felt, the electrode sleeve assembly and the insulation felt used are wrapped around the bottom of the copper electrode, affecting the service life of the copper electrode and the safe operation of the equipment, the utility model proposes an electrode sleeve structure for high-temperature purification equipment, the purpose of which is to improve the hardware structure of the electrode sleeve assembly to avoid the electrode assembly being wrapped around the bottom of the copper electrode and affecting the service life of the copper electrode.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: an electrode sleeve structure for high-temperature purification equipment, comprising an electrode sleeve, wherein the electrode sleeve passes through an inclined thermal insulation felt, the inclination angles of the two end faces of the electrode sleeve are consistent with the inclination angles of the inclined thermal insulation felt, and the upper end face of the electrode sleeve is higher than the upper end face of the inclined thermal insulation felt;

[0006] A graphite electrode is fitted in the gap of the electrode sleeve, one end of the graphite electrode is connected to a copper electrode, and the end of the copper electrode connected to the graphite electrode is higher than the upper end surface of the electrode sleeve;

[0007] The electrode sleeve is provided with a graphite support piece on its outer sleeve, and the graphite support piece is placed on the upper end surface of the inclined thermal insulation felt. The graphite support piece is also provided with a fixing device, and the fixing device is connected to the electrode sleeve.

[0008] Furthermore, the graphite support is a ring-shaped structure, which is compatible with the electrode sleeve.

[0009] Furthermore, a heat shielding felt is provided at one end of the graphite electrode away from the copper electrode.

[0010] Furthermore, the thermal insulation felt is arranged around the graphite electrode.

[0013] Furthermore, a heater is provided at the other end of the graphite electrode.

[0014] Furthermore, the lower end surface of the electrode sleeve is flush with the lower end surface of the inclined thermal insulation felt.

[0015] Compared with the prior art, the present invention has the following beneficial effects: the two end faces of the electrode sleeve of the present invention are consistent with the inclination angle of the inclined insulation felt, and there is no need to set up an upper insulation felt, which avoids the upper insulation felt wrapping the copper electrode, effectively reduces the temperature of the copper electrode, extends the service life of the copper electrode, and ensures the safe operation of high-temperature purification equipment; the setting of the electrode sleeve structure of the present invention does not require further lowering the temperature of the cooling water to lower the temperature of the copper electrode, reduces the energy consumed by the cooling water to cool the temperature of the copper electrode, and reduces the operating cost of the equipment.

DETAILED DESCRIPTION

[0024] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0025] like Figures 1 to 6 As shown, the utility model provides an electrode sleeve structure for high-temperature purification equipment, including an electrode sleeve 1, which passes through an inclined thermal insulation felt 2. The inclination angles of the upper and lower end faces of the electrode sleeve 1 are consistent with the inclination angles of the inclined thermal insulation felt 2. The upper end face of the electrode sleeve 1 is higher than the upper end face of the inclined thermal insulation felt 2, and the lower end face of the electrode sleeve 1 is flush with the lower end face of the inclined thermal insulation felt 2.

[0026] A graphite electrode 3 is fitted into the gap within the electrode sleeve 1. Both ends of the graphite electrode 3 extend through the ends of the electrode sleeve 1. One end of the graphite electrode 3 is fixedly connected to a copper electrode 4, and the other end of the graphite electrode 3 is connected to a heater 10. The end of the copper electrode 4 connected to the graphite electrode 3 is higher than the upper end surface of the electrode sleeve 1, meaning that the bottom of the copper electrode 4 is higher than the height of the corresponding inclined carbon felt below it. Compared to traditional graphite electrode 3 sleeve 1 assemblies, this ensures that the copper electrode 4 is not circumferentially wrapped by the upper insulation felt 8, facilitating heat dissipation from the copper electrode 4.

[0027] The electrode sleeve 1 is provided with a graphite support 5, which is an annular structure and cooperates with the electrode sleeve 1. That is, the graphite support 5 is preferably a graphite ring. The graphite support 5 and the electrode sleeve 1 are clearance-matched, and the graphite support 5 is fixed on the inclined thermal insulation felt 2 to ensure that the graphite support 5 does not slide relative to the inclined thermal insulation felt 2.

[0028] A fixture 6 is placed on the upper end of the graphite support 5 and is fixedly connected to the electrode sleeve 1. The graphite support 5 shares the weight of the fixture 6 and the electrode sleeve 1, preventing the fixture 6 from crushing the inclined insulation felt 2. Specifically, several fixing holes are provided at the upper end of the electrode sleeve 1, which are threadedly connected to the fixture 6. In this embodiment, two fixing holes are provided, arranged opposite each other, that is, the straight line between the two fixing holes is the diameter of the electrode sleeve 1. One end of the fixture 6 corresponds to the fixing hole one by one, and the other end of the fixture 6 is placed on the graphite ring. The fixture 6 is preferably a carbon-carbon screw.

[0029] Those skilled in the art may also make adaptive adjustments to the structure of the graphite support 5 , as long as it can cooperate with the electrode sleeve 1 , be fixed on the inclined thermal insulation felt 2 , and serve as a support for the fixing device 6 fixedly connected to the graphite support 5 .

[0030] A heat shielding felt 7 is provided at one end of the graphite electrode 3 away from the copper electrode 4 , that is, a heat shielding felt 7 is provided at the lower end surface of the circumferential electrode sleeve 1 of the graphite electrode 3 to ensure high-temperature purification effect in the furnace.

[0031] The two end faces of the electrode sleeve 1 of the present invention are aligned with the inclination angle of the inclined thermal insulation felt 2. The upper end face of the electrode sleeve 1 is higher than the upper end face of the inclined thermal insulation felt 2. A fixing device 6 is fixedly connected to the upper end of the electrode sleeve 1. The fixing device 6 is placed on a graphite support member 5 sleeved on the outer wall of the electrode sleeve 1. The lower end face of the graphite support member 5 is placed on the upper end face of the inclined thermal insulation felt 2, thereby fixing the electrode sleeve 1 to the inclined thermal insulation felt 2. The structure of the electrode sleeve 1 of the present invention ensures that the circumference of the copper electrode 4 is not wrapped by the upper thermal insulation felt 8, thereby reducing the temperature of the copper electrode 4 and increasing the service life of the copper electrode 4.
