Description

Technical Field

[0001] This utility model belongs to the field of graphitization furnace cooling technology, specifically relating to a rapid cooling device for graphitization furnaces based on the synergy of circulating water cooling and air cooling. Background Technology

[0002] Cooling is crucial in the graphitization furnace production process. With the widespread application of graphite materials in new energy, electronics, and other fields, higher demands are placed on the production efficiency and product quality of graphitization furnaces. Traditional graphitization furnace cooling methods are relatively simple, typically employing only air cooling or water cooling. Air cooling alone has limited heat dissipation efficiency and a slow cooling rate, significantly extending the production cycle and increasing production costs; while water cooling alone, although providing better cooling performance, consumes a lot of energy. Utility Model Content

[0003] The purpose of this invention is to provide a rapid cooling device for graphitization furnaces based on the synergy of circulating water cooling and air cooling. This device can rapidly cool the furnace body by combining water cooling and air cooling, and can concentrate cooling water to cool the gas during the cooling process, thereby reducing the energy wasted during the cooling of the graphitization furnace body.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A rapid cooling device for a graphitization furnace based on the synergy of circulating water cooling and air cooling includes a graphitization furnace body, a circulation pipe fixedly connected to the side of the graphitization furnace body, both ends of the circulation pipe being connected to the graphitization furnace body, and a high-temperature resistant fan and a water-cooled radiator fixedly connected to the circulation pipe.

[0006] The water-cooled radiator includes a water storage tank, the front and rear ends of which are connected to a circulation pipe. The water storage tank is equipped with a water-cooling cooling channel, which contains cooling water, refrigeration equipment, and cooling water circulation spraying equipment. The vertical cross-sectional dimensions of the water-cooling cooling channel are adjustable.

[0007] Furthermore, electric push rods are fixedly connected to both the left and right sides of the water storage tank, and the output end of the electric push rod is fixedly connected to a side plate that is slidably connected inside the water storage tank.

Detailed Implementation

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-6 As shown, a rapid cooling device for a graphitization furnace based on the synergy of circulating water cooling and air cooling includes a graphitization furnace body 1. A circulation pipe 2 is fixedly connected to the side of the graphitization furnace body 1, and both ends of the circulation pipe 2 are connected to the graphitization furnace body 1. A high-temperature resistant fan 3 and a water-cooled radiator 4 are fixedly connected to the circulation pipe 2. When the high-temperature resistant fan 3 is started, the gas inside the graphitization furnace body 1 can be driven into the circulation pipe 2 and then enter the graphitization furnace body 1 again through the circulation pipe 2. The gas inside the graphitization furnace body 1 can be circulated by the air force to achieve air cooling and heat dissipation inside the graphitization furnace body 1. At the same time as air cooling and heat dissipation, the water-cooled radiator 4 performs water cooling and heat dissipation on the flowing air, so as to quickly cool the graphitization furnace body 1.

[0024] The water-cooled radiator 4 includes a water storage tank 5. The front and rear ends of the water storage tank 5 are connected to the circulation pipe 2. The water storage tank 5 is equipped with a water-cooling cooling channel. The water-cooling cooling channel is equipped with cooling water, refrigeration equipment and cooling water circulation spraying equipment. The refrigeration equipment can be a compression refrigeration machine, an absorption refrigeration machine or a semiconductor refrigeration chip.

[0025] At this time, the refrigeration equipment is started to cool the cooling water inside the water cooling channel. Then, the cooling water circulation spraying equipment is started to spray the cooling water inside the water cooling channel, so that the cooling water can come into contact with the gas inside the water cooling channel more evenly, and complete the cooling of the gas. The cooled gas can re-enter the graphitization furnace body 1 to cool the inside of the graphitization furnace body 1.

[0026] like Figures 3-4 As shown, the vertical cross-sectional dimensions of the water-cooling channel are adjustable. By adjusting the vertical cross-sectional dimensions of the water-cooling channel, the volume of the water-cooling channel can be controlled, so that the volume of the water-cooling channel matches the amount of gas entering the water-cooling channel. This allows the gas entering the water-cooling channel to be evenly distributed inside the water-cooling channel, effectively utilizing the cooling water evenly distributed inside the water-cooling channel to cool the gas evenly distributed inside the water-cooling channel. Concentrated cooling water to cool the gas can effectively and rapidly cool the graphitization furnace body 1, and reduce the energy wasted during the cooling of the graphitization furnace body 1.

[0027] Among them, such as Figures 2-4 As shown, electric push rods 7 are fixedly connected to both the left and right sides of the water storage tank 5. The output end of the electric push rod 7 is fixedly connected to a side plate 8 that is slidably connected inside the water storage tank 5. The water cooling channel is the space between the two side plates 8 of the water storage tank 5. At this time, by adjusting the electric push rod 7 to drive the side plate 8 to move, the distance between the two side plates 8 can be adjusted, the width of the water cooling channel can be controlled, and the vertical cross-sectional dimensions of the water cooling channel can be changed relatively easily.

[0028] like Figures 3-6 As shown, the cooling water circulation spraying device includes a circulating water pump 17 fixedly connected to the middle of the lower side of the water storage tank 5. The circulating water pump 17 is connected to multiple water outlet boxes 10 located on the upper side of the water cooling channel through a connecting water pipe 16. Several cooling water nozzles are fixedly connected to the lower side of the water outlet box 10. At this time, by starting the circulating water pump 17, the cooling water in the lower part is transported into the connecting water pipe 16 and then into the water outlet box 10, and sprayed downward through the cooling water nozzles.

[0029] Inside the water storage tank 5, there is also a filter screen 6 that covers the outside of the circulating water pump 17. The filter screen 6 can filter the water entering the circulating water pump 17.

[0030] Multiple water outlet boxes 10 can be fixedly connected to the upper side inside the water cooling channel, or they can be movably installed inside the upper side of the water cooling channel. In this technical solution, multiple crossbars 9 are fixedly connected to the upper side inside the water storage tank 5. Two side plates 8 and multiple water outlet boxes 10 are slidably connected to the outside of the multiple crossbars 9. A first return spring 11 sleeved on the outside of the crossbar 9 is fixedly connected between two adjacent water outlet boxes 10. At this time, when the side plate 8 moves, it will squeeze the first return spring 11, thereby adjusting the position of the water outlet boxes 10 through the multiple first return springs 11, so that the water outlet boxes 10 are automatically and evenly distributed, so that the cooling water sprayed from the water outlet boxes 10 can be more evenly distributed inside the water storage tank 5.

[0031] At this time, a second return spring 12 is fixedly connected between the side plate 8 and the water outlet box 10 adjacent to the side plate 8. The distance between the water outlet box 10 and the side plate 8 can be automatically adjusted by the setting of the second return spring 12.

[0032] like Figures 3-4 As shown, a through hole is provided on the side plate 8, and a crossbar 9 is slidably connected inside the through hole. A groove 13 can be provided on the outer side wall of the side plate 8, and another groove 13 can be provided on the inner wall of the through hole. A sealing ring 14 is installed inside the groove 13. An air pump 15 can be fixedly connected to the outer side of the side plate 8. The air pump 15 is connected to the sealing ring 14. At this time, by starting the air pump 15 to release the air from the sealing ring 14, the volume of the sealing ring 14 is reduced, which reduces the friction when the side plate 8 moves, making it easier for the side plate 8 to move. After the side plate 8 has moved, the air pump 15 is started to inflate the sealing ring 14, which expands the volume of the sealing ring 14, thereby improving the sealing performance of the side plate 8.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
