Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode production, in particular to a spray cooling device for graphite electrode production. Background Art

[0002] Graphite electrodes need to be calcined during the production process. After the graphite electrodes are formed, their own temperature is relatively high. At this time, the graphite electrodes are cooled so that the graphite electrodes can be quickly cooled and formed. For example, in a cooling rack for graphite electrode production disclosed in Chinese patent literature (patent number: CN202222316942.3), the graphite electrodes are cooled by winding a cooling water pipe on the surface of the connecting tube to cool the graphite electrodes inside the connecting tube. The cooling water in the cooling pipe and the graphite electrodes are separated by the cooling water pipe and the side wall of the connecting tube. The cooling water cannot directly cool the graphite electrodes, and the cooling speed of the graphite electrodes is relatively slow. In addition, four groups of connecting tubes are vertically arranged, and only four groups of graphite electrodes can be cooled at a time. After cooling, the graphite electrodes are taken out and replaced with cooled graphite electrodes. The cooling process of the graphite electrodes is relatively cumbersome.

[0003] To this end, we propose a spray cooling device for graphite electrode production. Utility Model Content

A connecting pipe 9 is arranged on the side, a water inlet pipe 10 is arranged on the right side of the water pump 8, a baffle 11 is arranged in the middle of the fixed frame 1, a through hole 12 is arranged in the middle of the baffle 11, a water outlet pipe 13 is arranged at the bottom of the through hole 12, a support plate 15 is arranged on the left end of the top of the water tank 14, a guide plate 16 is arranged on the right side of the support plate 15, and side plates 17 are arranged at both the front and rear ends of the guide plate 16 to cool the graphite electrode. The graphite electrode is hoisted onto the guide roller 7 arranged on the fixed frame 1. Since the left end of the fixed frame 1 is higher than the right end, the graphite electrode is subjected to gravity. The graphite electrode slides to the right through the guide roller 7. When the graphite electrode slides, the motor 5 and the water pump 8 are started. The water pump 8 extracts cooling water from the water tank 13 through the water inlet pipe 10, and delivers it to the ring pipe 3 through the connecting pipe 9. The cooling water is sprayed out through the water outlet holes 31 arranged on the inner wall of the inner ring of the ring pipe 3 to cool the graphite electrode. The water outlet holes on the inner wall of the inner ring of the ring pipe 3 are arranged in a circle, and the graphite electrode is cooled in all directions to speed up the cooling of the graphite electrode. The ring pipe 3 is provided with two groups. The first group of ring pipes first cools the graphite electrode for preliminary cooling. The graphite electrode continues to move after being cooled, and the electrode 5 drives the fan blades 6 to rotate to air-cool the graphite electrode. Since the graphite electrode is first water-cooled, there is residual moisture on the surface of the graphite electrode. While the electrode 5 drives the fan blades 6 to rotate to air-cool the graphite electrode, the evaporation of moisture on the surface of the graphite electrode is accelerated, and the heat of the graphite electrode is taken away, so that the graphite electrode is quickly cooled. The graphite electrode after air cooling moves to the second group of ring tubes 3, and the second group of ring tubes 3 continue to water-cool the graphite electrode, thereby further accelerating the cooling speed of the graphite electrode.

[0020] The upper part of both sides of the inner surface of the fixing frame 1 is provided with mounting holes 101, and both ends of the guide roller 7 are provided with mounting shafts 71, and the guide roller 7 rolls in the mounting holes 101 by the mounting shafts 71;

[0021] The bottom end of the water inlet pipe 10 passes through the guide plate 16 and extends into the bottom of the water tank 14. The guide plate 16 is provided with a hole matched with the water inlet pipe 10. The guide plate 16 is stepped. Only a part of the water used to cool the graphite electrode will evaporate, and the rest will drip downward onto the baffle 11, and enter the water outlet pipe 13 through the through hole 12 provided in the middle of the baffle 11, flow to the guide plate 16, and flow to the water tank 14 through the guide plate 16 for recycling. The guide plate 16 is stepped. When the cooling water passes through the guide plate 16, the cooling water flows on the horizontal surface and the vertical surface of the guide plate 16, increasing the contact area between the cooling water and the air, so that the cooling water after cooling the graphite electrode is quickly cooled, so that the cooling water can quickly cool the graphite electrode during the recycling process of the cooling water;

[0022] The right end of the water outlet pipe 13 passes through the support plate 15, and the left end of the guide plate 16 is located at the bottom of the water outlet pipe 13. The cooling water flowing through the water outlet pipe 13 to the guide plate 16 flows through the guide plate 16 to the water tank 14 for recycling;

[0023] The ring tube 3 is fixedly connected to the upper part of the fixing frame 1. The upper part of the fixing frame 1 is provided with a fixing groove matched with the fixing frame 1. The water outlet hole 31 is provided around the inner wall surface of the inner circle of the ring tube 3. The cooling water in the ring tube 3 is sprayed out in all directions through the water outlet hole 31 to quickly cool the graphite electrode. The left end of the connecting pipe 9 is connected to the ring tube 3.

[0024] The left end of the fixing frame 1 is higher than the right end and is tilted. The fixing frame is tilted, and the graphite electrode on the guide roller 7 slides through the guide roller 7 by itself under the action of gravity.

[0025] Working principle: To cool the graphite electrode, hoist the graphite electrode onto the guide roller 7 provided on the fixed frame 1. Since the left end of the fixed frame 1 is higher than the right end, the graphite electrode slides to the right through the guide roller 7 under the action of gravity. While the graphite electrode is sliding, the motor 5 and the water pump 8 are started. The water pump 8 draws cooling water from the water tank 13 through the water inlet pipe 10, and delivers it to the ring tube 3 through the connecting pipe 9. The water is sprayed out through the water outlet 31 provided on the inner wall of the inner ring of the ring tube 3 to cool the graphite electrode. The water outlet holes on the inner wall of the inner ring of the ring tube 3 are provided in a circle, and the graphite electrode is cooled in all directions to accelerate the cooling of the graphite electrode. , and two groups of ring tubes 3 are provided. The first group of ring tubes first cools down the graphite electrode. After the preliminary cooling, the graphite electrode continues to move. The electrode 5 drives the fan blade 6 to rotate to air-cool the graphite electrode. Since the graphite electrode is first water-cooled, there is residual moisture on the surface of the graphite electrode. While the electrode 5 drives the fan blade 6 to rotate to air-cool the graphite electrode, the evaporation of moisture on the surface of the graphite electrode is accelerated, the heat of the graphite electrode is taken away, and the graphite electrode is quickly cooled.
