[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0021] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of an electrode device for producing crystalline hafnium provided by the utility model; Figure 2 for Figure 1 A schematic diagram of a cross-sectional structure of a copper electrode of an electrode device for producing crystalline hafnium is shown; Figure 3 for Figure 1 The cross-sectional structure diagram of the electrode device for producing crystalline hafnium is shown. The electrode device for producing crystalline hafnium comprises: a copper electrode mechanism 1 and a molybdenum electrode 2;
[0022] The molybdenum electrode 2 is detachably mounted on the bottom end of the copper electrode mechanism 1;
[0023] The copper electrode mechanism 1 comprises a copper column 11, a circular vertical groove 12 is vertically opened at the bottom end of the copper column 11, a plurality of sliding grooves 13 are horizontally opened on the inner side wall of the vertical groove 12 and are all arranged along the radial direction of the copper column 11, the plurality of sliding grooves 13 are evenly spaced along the circumferential direction of the copper column 11, the interiors of the plurality of sliding grooves 13 are respectively connected with sliding columns 14 in a horizontal sliding manner along the length direction thereof, the inner ends of the plurality of sliding columns 14 are all fixedly connected with connecting pipe sheets 15 with a semi-circular cross section, the inner surfaces of the plurality of connecting pipe sheets 15 are all provided with internal threads 16, the outer surfaces of the plurality of sliding columns 14 and located inside the vertical groove 12 are all sleeved with springs 17, the two ends of the spring 17 are respectively fixedly connected to the outer surface of the connecting pipe sheet 15 and the inner surface of the vertical groove 12;
[0024] The internal threads 16 of a plurality of connecting segments 15 are spliced together to form a thread groove.
[0025] The top end of the molybdenum electrode 2 is vertically fixedly connected with a threaded column 8 corresponding to and adapted to the threaded groove, and the molybdenum electrode 2 is detachably mounted on the bottom end of the copper electrode mechanism 1 through the threaded column 8 .
[0026] The copper electrode mechanism 1 and the molybdenum electrode 2 of the device are connected by threaded connection. A vertical groove 12 is opened at the bottom end of the copper electrode mechanism 1. A plurality of connecting tube sheets 15 are arranged inside the vertical groove 12. The plurality of connecting tube sheets 15 are spliced to form a tubular structure. A threaded groove composed of a plurality of internal threads 16 is arranged inside the tubular structure. The molybdenum electrode 2 can be detachably installed on the bottom end of the copper electrode through the threaded column 8 at its top. In actual use, when the overall temperature of the electrode rises, the copper electrode expands. At this time, the plurality of connecting tube sheets 15 will move outward without directly squeezing the threaded column 8 of the molybdenum electrode 2. After the temperature drops, the plurality of connecting tube sheets 15 will return to the initial state. The two electrodes will not be deformed due to expansion, and there will be no problem when the two need to be separated.
[0027] The connecting pipe piece 15 can slide horizontally inside the vertical groove 12 under the action of the sliding column 14, so it has a certain activity space. When the copper electrode mechanism 1 expands as a whole, the connecting pipe piece 15 will move outward a certain distance to avoid its internal structure from being squeezed by the threaded column 8.
[0028] A ceramic ring 3 is sleeved on the lower part of the outer surface of the molybdenum electrode 2, and a cap 4 is arranged on the outer surface of the ceramic ring 3. A through hole is vertically penetrated through the bottom end of the cap 4, and the bottom end of the molybdenum electrode 2 extends downward through the through hole.

A sleeve 7 is vertically fixedly connected to the inner ring surface of the flange ring 6. The bottom end of the sleeve 7 extends to the upper surface of the ceramic ring 3. The molybdenum electrode 2 and the copper electrode mechanism 1 are both located inside the sleeve 7.
[0030] The ceramic ring 3, the cap 4 and the sleeve 7 are the basic structure of the electrode, which is the prior art and will not be described in detail here. The flange ring 6 and the retaining ring 5 are connected by screws.
[0031] The cap 4 and the retaining ring 5 are both made of molybdenum.
[0032] The cap 4 and the retaining ring 5 are both made of molybdenum, which can play a blocking role. When the reaction occurs, due to the high reaction temperature, structures such as the flange ring 6 may also participate in the reaction, resulting in impure final crystalline hafnium. This problem can be avoided by blocking with the molybdenum retaining ring 5 and the cap 4.
[0033] The bottom end of the molybdenum electrode 2 is retracted to form a ladder-like structure.
[0034] When current passes through metal, the thinner the metal, the greater the resistance and the higher the temperature. The gradually thinner molybdenum electrode 2 can quickly heat up to meet the reaction conditions and improve production efficiency.
[0035] The working principle of the electrode device for producing crystalline hafnium provided by the utility model is as follows:
[0036] The copper electrode mechanism 1 and the molybdenum electrode 2 of the device are connected by threaded connection. A vertical groove 12 is opened at the bottom end of the copper electrode mechanism 1. A plurality of connecting tube sheets 15 are arranged inside the vertical groove 12. The plurality of connecting tube sheets 15 are spliced to form a tubular structure. A threaded groove composed of a plurality of internal threads 16 is arranged inside the tubular structure. The molybdenum electrode 2 can be detachably installed on the bottom end of the copper electrode through the threaded column 8 at its top. In actual use, when the overall temperature of the electrode rises, the copper electrode expands. At this time, the plurality of connecting tube sheets 15 will move outward without directly squeezing the threaded column 8 of the molybdenum electrode 2. After the temperature drops, the plurality of connecting tube sheets 15 will return to the initial state. The two electrodes will not be deformed due to expansion, and there will be no problem when the two need to be separated.
