Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrolytic aluminum carbon, and particularly relates to a cooling equipment for green anode carbon blocks of electrolytic aluminum. BACKGROUND

[0002] In the production process of electrolytic aluminum anode carbon blocks, the green anode carbon blocks need to be cooled after kneading and forming, and then can be stacked and transported into the baking process.

[0003] The mainstream green anode cooling in China is water bath and natural cooling. The green anode carbon blocks after being formed by vibration are transported into a cooling water pool by a plate chain, a suspension chain or a hanging frame, and then are taken out of water after water bath for 30-150 minutes, and enter the natural cooling stage of a plate conveyor. The current green anode cooling process of each enterprise is controlled according to the traditional production experience of water bath cooling time, forming temperature and water temperature, and there is no unified standard.

[0004] The mainstream green anode cooling process abroad is spray cooling combined with natural cooling or pure natural cooling. After the green anode is formed by vibration, compressed air is used to atomize soft water, and the atomized water mist is sprayed onto the surface of the high-temperature green body. Since the small particles of the water mist have small specific surface area, the forced convection heat transfer coefficient is large, and the heat carried away is more, and the cooling effect is better. However, the cost of this cooling is much higher than that of water bath, and it is not widely used in domestic production.

[0005] The most important thing is that in the prior art, almost all carbon plants do not pay attention to the relationship between the quality problem (crack) of the anode carbon block and the cooling process, and believe that there is no correlation problem. In recent years, the applicant has found that the strength of the anode carbon block as an important quality indicator is related to the forming temperature, cooling time and cooling temperature, and is trying to find a specific and feasible method for establishing a green anode cooling model.

[0006] The biggest technical problem encountered in this research and development process is that the cooling production line cannot be used as a long-term experimental equipment. This is because the process parameters of the production line have been accumulated for many years to achieve the lowest rejection rate and the most reliable quality. If the parameters are adjusted for research and experiments, the following problems will inevitably occur: 1. The cooling line is long, and its cooling time is related to the subsequent stacking process. At present, the stacking process is an automatic program, and adjustment of the cooling time needs to be matched with the change of the stacking process, which is difficult to achieve on the production line; 2. The circulating water temperature parameter adjustment seems convenient, but the length of the cooling pool of the whole line exceeds 30 meters, the temperature rise and fall of the circulating water cannot be quickly fed back to the temperature rise and fall of the cooling pool, and the temperature change of the pool still needs a long time; during the time from the initial temperature to the target temperature, the quality of the produced anode carbon block is affected by the change of the cooling temperature, and the unqualified anode products can be eliminated in the quality inspection, and the products with small influence can also be eliminated in the subsequent electrode use due to the unexpected service life, which is related to the electrode replacement operation and has huge cost; 3. In the initial stage of the anode cooling model experiment, in order to study the rules between experimental elements, the actual anode carbon block is generally scaled down to make special experimental carbon blocks for rule research; after the general rules of different elements are found, the actual anode carbon block is used for experiment, and the production lines of electrolytic plants are different in different periods, and different sizes of anode carbon blocks are needed for different production lines to produce electrodes, so a small anode cooling device that can meet the experimental requirements of various specifications is needed; 4. The research and development of general enterprises are separated from production, and only after multiple successful pilot tests can the actual production be gradually promoted. In the initial stage of research and development, in addition to laboratory equipment, existing parameters can only be collected on different production lines, and production parameters cannot be set according to the needs of research and development experiments.

[0007] The above problems directly affect the research of the relationship between the quality of anode carbon blocks and the forming temperature, cooling time and cooling temperature, so a small cooling device that can be used for experiments and is convenient to adjust parameters is needed. Considering different processes at home and abroad, it is best to combine water, mist and air cooling.

[0008] The angle of the water mist nozzle and the air blowing device in the existing cooling device of other industries is usually fixed, and such a device is not suitable for establishing the correlation between experimental elements and product quality in the research and development scene, which is easy to cause one-sided overcooling of the carbon block. Long-term operation of this fixed-point cooling will cause thermal shock or thermal stress concentration, and then cause cracks in the carbon block due to internal stress, affecting the quality of the finished product, so it is not possible to determine whether the quality of the carbon block is affected by the experimental factors or the fixed-point cooling.

[0009] Based on the problems in the above background technology, the research and development personnel propose a small anode carbon block cooling device for electrolytic aluminum anode that can be used for experiments and is convenient to adjust parameters. SUMMARY

[0030] The working process of the mounting structure in the embodiment is as follows: When it is needed to use the device to cool the anode carbon block (hereinafter referred to as carbon block), the user adjusts the relative rotation angle of the fixed shell 4 and the rotating shell 5 according to the size of the carbon block, connects the two rotating rods 3 with external power, the user first pulls the two sliding doors 2 apart from both sides, then adjusts the position of the bearing block 29 according to the size of the carbon block, so that the cooling shell 26 is located in the middle area of the side surface of the carbon block: the user rotates the second threaded shell 31, the second threaded shell 31 drives the second threaded rod 30 to move through the thread, the second threaded rod 30 drives the bearing block 29 to move through the second connecting frame 28, until the bearing block 29 moves to the preset position, the user adjusts the vertical distance between the sprayer 11 and the measuring block 10 according to the requirement: the user rotates the two first threaded shells 15 at the same time, the first threaded shell 15 drives the first threaded rod 13 to move through the thread, the first threaded rod 13 drives the sprayer 11 to move to the designated position, then the user rotates the measuring block 10, so that the measuring block 10 is rotated to be horizontal (as shown in the figure), at the same time, the torsional spring between the first connecting rod 8 and the measuring block 10 is stored, at this time, the adjustment is completed.

[0031] After the adjustment, the user will transport the carbon block to the two bearing blocks 29, at this time the two cooling shells 26 contact the carbon block, as the carbon block continues to move backward, the carbon block contacts the blowing shell 12, and the blowing shell 12 is in a vertical state (as shown in the figure), and the torsion spring between the second connecting rod 9 and the blowing shell 12 is stored at this time, the measuring block 10 and the upper roller of the blowing shell 12 are both in contact with the surface of the carbon block (contacting to prevent displacement), then the user closes the two sliding doors 2, at this time the carbon block loading step is completed.

[0032] After the carbon block loading is completed, the user drives the two rotating rods 3 to rotate synchronously and slowly by external power, the rotating rod 3 drives the fixed shell 4 and the rotating shell 5 and the parts thereon to rotate synchronously, taking the rotating process of the rotating shell 5 as an example, the rotating shell 5 drives the sliding rod 6 thereon to rotate, the sliding rod 6 drives the sliding ring 7 to rotate, the two sliding rings 7 drive the measuring block 10 to rotate synchronously through the first connecting rod 8, the measuring block 10 moves horizontally on the carbon block, the torsion spring between the first connecting rod 8 and the measuring block 10 is twisted synchronously, and the sliding ring 7 slides on the sliding rod 6, at this time the sliding rod 6 rotates counterclockwise (in the direction of the right view), the user synchronously starts the sprayer 11 (the cooling water supplied by the outside is transported into the sprayer 11 through the water supply pipe 161, the fixed rod 16, the rotating shell 5, the sliding rod 6 and the connecting pipe 17), the sprayer 11 sprays water mist to the carbon block and cools the carbon block, in the rotating process, the blowing shell 12 is the same (the gas supplied by the outside is transported into the blowing shell 12 through the gas supply pipe 162, the fixed rod 16, the fixed shell 4, the sliding rod 6 and the gas supply pipe 23), through the cooperation of the sprayer 11 and the blowing shell 12, the carbon block is continuously rotated and wrapped for cooling, preventing the carbon block from being excessively cooled on one side, and the blowing shell 12 is located at the rear side of the moving path of the sprayer 11, that is, after the sprayer 11 sprays water mist onto the carbon block, as the blowing shell 12 moves, the airflow blown from the blowing shell 12 assists the evaporation of the water mist (that is, accelerates heat exchange) to improve the cooling efficiency.

[0033] In the above cooling process (the edge is double-cooled by the double sides, if the spraying amount is not limited, it will cause the edge to be cooled too fast, that is, the cooling is not uniform, which affects the quality of the carbon block), when the sprayer 11 moves from the upper middle part to the front upper side edge of the carbon block, the sliding ring 7 moves upward along the sliding rod 6 under the drive of the first connecting rod 8, and the sliding ring 7 drives the first adjusting ring 19 to move upward through the force supply rod 20. Due to the presence of the one-way valve on the first adjusting ring 19, only part of the through holes on the first adjusting ring 19 can flow hydraulic oil, and the upper part of the first adjusting ring 19 flows part of the hydraulic oil to the adjusting shell 21 through the pipeline, thereby extruding the second adjusting ring 22, making the second adjusting ring 22 extrude the connecting pipe 17, reducing the flow area of the connecting pipe 17, and thereby achieving the purpose of inhibiting the spraying amount of the water mist, that is, the spraying amount of the water mist gradually decreases from the middle to the two sides, so as to ensure the uniformity of the cooling. In the above process of moving the first adjusting ring 19 upward, part of the hydraulic oil flows downward between the first adjusting ring 19 and the pressure compensation ring 191 through the through hole without the one-way valve. In this process, the pressure compensation ring 191 will move upward with the first adjusting ring 19 by a distance, and it will decrease relative to the first adjusting ring 19 with the increase of the amount of hydraulic oil therebetween. When the sprayer 11 rotates to the front side of the carbon block, the sliding ring 7 moves away from the adjusting shell 21 under the drive of the tension spring between the sliding ring 7 and the sliding rod, thereby making the first adjusting ring 19 lose the stable pressure supply to the second adjusting ring 22, and the second adjusting ring 22 gradually resets, and the flow area of the connecting pipe 17 gradually recovers, thereby gradually increasing the spraying amount of the sprayer 11 when it moves from the front upper side edge of the carbon block to the front middle part. Through the cooperation of the first adjusting ring 19 and the second adjusting ring 22, the spraying rule of the water mist is controlled, so that the closer the sprayer 11 is to the edge, the less the spraying amount of the water mist, thereby preventing the cooling speed of the edge of the carbon block from being too fast, and thereby ensuring the quality of the finished product.

[0034] In the process of continuously rotating the sprayer 11 around the carbon block to cool it, part of the cooling water flows into the middle cavity of the connecting piece 25 through the fixed rod 16, and the cooling water in the middle cavity of the connecting piece 25 flows into the cooling shell 26 through the water inlet pipe 32, thereby cooling the left and right sides of the carbon block. The water in the cooling shell 26 flows back to the front and rear cavities of the connecting piece 25 through the first return pipe 34 and the second return pipe 35, and then is discharged to the outside through the waterproof pipe 163, thereby completing the cooling of the left and right sides of the carbon block.

[0035] The above process is repeated to cool the carbon block until the carbon block is cooled to the required degree of the experiment, and the carbon block is taken out of the machine shell 1 for natural cooling. When needed, other carbon blocks are loaded for cooling until all the experimental carbon blocks are cooled completely, at which time the device is completed.

[0036] In the future, further exploration of the establishment of green anode cooling model, there is a work scene is to close the sprayer 11, open the blowing shell 12, the carbon block is cooled alone, the current green anode cooling model does not consider the wind cooling factor, so this working scene is no longer described.
