Description

Technical Field

[0001] The utility model relates to the technical field of prebaked anode cooling, in particular to a temperature reduction device for prebaked anode production. Background Art

[0002] After high-temperature treatment, the prebaked anode may have certain thermal stress and deformation on its surface. If it is suddenly transferred from a high-temperature environment to a room temperature environment, it may cause structural instability, or even cracks or deformation. Through the cooling process, the temperature can be gradually lowered, the thermal stress can be reduced, and it is beneficial to maintain the structural stability of the anode.

[0003] At present, the utility model patent with patent number CN 217686654 U discloses a pre-baked anode carbon block material cooling device, including a base, a workbench is installed on the top of the base, a work box is installed on the top of the workbench, a strip opening is opened on one side of the work box, and a fixed plate is slidably connected to the bottom inner wall of the work box. A mesh support plate is installed on the top of the fixed plate. When the nozzle is spraying cold water, the rotating mechanism will drive the hollow rotating column to rotate, and then the water outlet pipe and the nozzle will rotate to evenly spray the cold water onto the carbon block body, thereby improving the cooling efficiency of the carbon block body, and the sprayed water will flow into the water tank again through the recovery pipe, so that it can be recycled.

[0004] However, the above patent uses cold water to cool the prebaked anode, which will cause the high-temperature prebaked anode to suddenly come into contact with cold water, causing a thermal shock effect, resulting in a rapid drop in the surface and internal temperature of the anode, which may cause thermal stress in the metal material, and even cause damage such as cracks and deformation. In addition, when spraying and cooling, water will contact the high-temperature prebaked anode and continuously form water vapor, which may cause corrosion of metal parts, especially if there are easily corroded metal materials such as iron and steel in the prebaked anode or the cooling device. Long-term exposure to a high-humidity water vapor environment may accelerate the corrosion rate of metal parts, thereby shortening the service life of the equipment. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a cooling device for prebaked anode production. By arranging a mobile platform with a mesh plate, the prebaked anode is mounted at the center of a cooling box, and the spray heads at the eight angles of the cooling box are used to achieve a uniform cooling effect on each surface of the prebaked anode. The water vapor generated during the cooling process is collected by the air collecting hood through the fan and enters the condenser through the water pipe for condensation and then re-enters the water tank. The water in the spraying process re-enters the water tank through the water permeable holes, thereby improving the utilization rate of water resources and reducing the corrosion of metal parts inside the device caused by high-temperature and high-humidity water vapor, thereby extending the service life of the device.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] A cooling device for prebaked anode production, the structure of which is as follows Figure 1-Figure 6 As shown, it includes a workbench 1, a cooling box 2 is arranged on one side of the top of the workbench 1, a water tank 6 connected to the cooling box 2 is arranged at the bottom of the workbench 1, and eight angles of the cooling box 2 are provided with spray heads 9 facing the center of the cooling box 2. A moving platform 12 is arranged inside the cooling box 2, and the moving platform 12 includes a column 13 and a mesh plate 17 installed on the top of the column 13. A water pipeline 7 connected to a plurality of spray heads 9 is arranged outside the cooling box 2, and the water pipeline 7 is connected to the water tank 6 through a water pump 8. An air collecting hood 3 is arranged on one side of the top of the cooling box 2, and a gas pipeline 4 is arranged on the top of the air collecting hood 3. The gas pipeline 4 is connected to the water tank 6 through a condenser 5, and a fan is arranged inside the water tank 6.

[0029] The prebaked anode after high temperature treatment is placed on the moving platform 12 and pushed into the cooling box 2, so that the prebaked anode is in the center of the cooling box 2. The water pump 8 works to transport the water in the water tank 6 through the water pipe 7 to the spray heads 9 set at eight angles of the cooling box 2. The prebaked anode is sprayed and cooled by the spray heads 9 at each angle. Since the table surface of the moving platform 12 for supporting the prebaked anode is a mesh plate 17, each surface of the prebaked anode can be sprayed by three spray heads 9 at the same time, ensuring that the prebaked anode is evenly sprayed with water, achieving uniform cooling of the prebaked anode, and avoiding uneven cooling speed on the surface of the prebaked anode, which causes damage such as cracks and deformation of the prebaked anode;

[0030] Since the bottom of the cooling box 2 is connected with the water tank 6, it can ensure that the water after spraying is directly recycled into the water tank 6, so as to achieve the effect of solving the water resource problem. At the same time, after the water contacts the prebaked anode after high-temperature treatment, water vapor is formed. Under the action of the fan, the water vapor enters the gas collecting hood 3 and enters the condenser 5 through the gas pipeline 4 to achieve condensation of the water vapor and be collected and utilized again. When the water vapor is slowly collected, the prebaked anode can be slowly cooled down, and the cooling effect of the prebaked anode is avoided due to the retention of water vapor in the cooling box 2. At the same time, the water vapor is reabsorbed and utilized, and the maximum utilization rate of water resources is achieved. At the same time, it can avoid the metal parts inside the device from being exposed to the high temperature and high humidity water vapor environment for a long time, which accelerates the corrosion rate of the metal parts, thereby increasing the service life of the equipment.

[0031] A box door 10 is provided on one side of the cooling box 2, and a through groove is provided on the top of the cooling box 2 on one side of the box door 10. The top of the box door 10 is slidably arranged through the through groove, and a push-pull plate 11 is provided on the top of the box door 10.

[0032] The box door 10 can be opened and closed up and down by the push-pull plate 11, ensuring that the interior of the cooling box 2 is separated from the external environment when cooling the prebaked anode, avoiding the leakage of water vapor inside the cooling box 2, causing external electrical appliances or circuits to malfunction due to water vapor, and at the same time ensuring that the prebaked anode is in a relatively stable environment for continuous cooling. After the cooling is completed and the water vapor is completely absorbed, the box door 10 is opened by the push-pull plate 11, and the prebaked anode is taken out by the moving platform 12.

[0033] A slide groove 15 is provided on the workbench 1 at the bottom of the cooling box 2, a slider 14 is provided at the bottom of the column 13 away from the box door 10, the slide groove 15 is adapted to the slider 14, and a walking wheel 16 is provided at the top of the column 13 close to the box door 10.

[0034] The slide groove 15 and the slider 14 cooperate with each other, so that the movable platform 12 can slide and limit the movable platform 12 at the same time, so as to prevent the water inside the slide groove 15 from flowing to the outside of the cooling box 2. Therefore, the slide groove 15 is only arranged on the working surface at the bottom of the cooling box 2. In order to enable the movable platform 12 to be moved to the outside of the cooling box 2, a walking wheel 16 is arranged at the bottom of the column 13 near the box door 10, so as to enable the movable platform 12 to be moved in and out of the cooling box 2, and at the same time prevent the water inside the cooling box 2 from flowing to the outside of the cooling box 2, thereby improving the practicality of the device.

[0035] The surface of the workbench 1 at the bottom of the cooling box 2 and the bottom of the chute 15 are both provided with water-permeable holes 18 .

[0036] Because there are eight spray heads 9, when cooling is performed, the spray heads 9 will continuously spray water, a part of which will be recovered after being vaporized through the gas collecting hood 3 into the condenser 5, and the remaining water can be recovered into the paper water tank 6 through the water permeable holes 18. Since the chute 15 is lower than the surface of the workbench 1, water accumulation in the chute 15 is avoided. Therefore, water permeable holes 18 are still provided at the bottom of the chute 15, so as to effectively recycle the water used for spray cooling and avoid the chute 15 and the slider 14 from being affected by the normal sliding of the slider 14 in the chute 15 due to long-term water accumulation.

[0037] The cooling box 2 has two side walls near the door 10 with sliding grooves, the door 10 is arranged in the sliding grooves, the workbench 1 at the bottom of the door 10 has a card slot, and the bottom of the door 10 is installed inside the card slot. The sides of the door 10 that abut against the cooling box 2 and the card slot are all provided with sealing strips.

[0038] The box door 10 can be effectively restricted by the sliding groove, and the through groove on the top of the cooling box 2 realizes the up and down movement of the box door 10. When the box door 10 is closed, the bottom of the box door 10 is inserted into the card slot. The cooperation between the sliding groove and the card slot and the box door 10 increases the air flow path. At the same time, the setting of the sealing strip can further prevent the leakage of internal water vapor. The internal temperature of the cooling box 2 can be more controlled, which is beneficial to the cooling of the prebaked anode.

[0039] Embodiment 2

[0040] On the basis of the first embodiment, a temperature sensor 19 and a constant temperature controller 20 are arranged inside the water tank 6 .

[0041] In order to avoid contact between cold water and the prebaked anode after high-temperature treatment, which would cause uneven cooling rate on its surface and lead to damage such as cracks and deformation of the prebaked anode, the thermostatic controller 20 and the temperature sensor 19 inside the water tank 6 cooperate with each other to control the water temperature inside the water tank 6 between 68-75°, ensuring that the water used for cooling is always kept in the required temperature range, reducing the temperature difference between the surface of the prebaked anode and the water, which can help reduce problems such as cracks or deformation that may occur in the material during rapid cooling, ensure the stability and quality of the product, and improve the yield rate of prebaked anode production.

[0042] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
