Description

Technical Field

[0001] This utility model relates to the field of kiln technology, and more specifically, to a rapid cooling device for kilns. Background Technology

[0002] Most lithium battery cathode material sintering kilns are fully automated atmosphere-protected roller kilns. These materials are in powder form, loaded in saggers, and slowly moved from the inlet to the outlet in the roller kiln while being heated and cooled. For example, application number "CN202322594227.0" proposes an atmosphere roller kiln adapted for high-yield and rapid cooling. This atmosphere roller kiln includes a kiln body and a cooling device. The cooling device is located at the top and / or bottom of the kiln body. The cooling device includes a mounting plate, fan blades, and a drive mechanism. The mounting plate is connected to the top and / or bottom of the kiln body. The drive mechanism is connected to the mounting plate and located outside the kiln body. The drive mechanism is connected to the fan blades to drive their rotation. The fan blades extend into the kiln body, and their rotation accelerates the air circulation inside the kiln body.

[0003] However, in the above technical solutions, relying solely on a single fan to drive the gas flow inside the furnace results in low gas flow efficiency, making it difficult to achieve uniform gas distribution within the furnace. This leads to an uneven temperature field inside the furnace, affecting material processing efficiency. Furthermore, when the saggers are stacked and transported, they are prone to sticking together, making it difficult for the airflow inside the furnace to penetrate to the surface of the saggers, significantly reducing heat transfer efficiency. Therefore, we propose a rapid cooling device for kilns to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 8As shown in the figure, this utility model embodiment proposes a rapid cooling device for a kiln, including a furnace body 1. Several conveying rollers 3 are installed at the lower end of the interior of the furnace body 1, and several saggers 4 are placed on the conveying rollers 3.

The output end of the first motors 6 movably penetrates the interior of the furnace body 1 and is connected to the first fans 7. A second fan 9 is movably installed at the lower end of the interior of the furnace body 1. A second motor 10 is installed on the lower surface of the furnace body 1, and the output end of the second motor 10 movably penetrates the interior of the furnace body 1 and is connected to the second fan 9. A second suction pipe 11 is installed through the upper rear side of the interior of the furnace body 1, and the second suction pipe 11... The auxiliary mechanism 2, connected to an external exhaust fan, includes a pressure plate 209. The pressure plate 209 is movably installed inside the furnace body 1. Several partition plates 210 are installed on the lower surface of the pressure plate 209. A first cylinder 208 is installed in the middle of the upper surface of the furnace body 1. The output end of the first cylinder 208 movably passes through the interior of the furnace body 1 and is connected to the pressure plate 209. The pressure plate 209 has a gas collecting groove 211 inside. Several suction holes 212 are provided through the lower end of the gas collecting groove 211. The suction holes 212 correspond one-to-one with the sagger 4 and are parallel vertically. Filter screens are installed inside the suction holes 212 respectively. A first suction pipe 213 is installed through the upper end of one side of the gas collecting groove 211. The pipe body of the first suction pipe 213 movably passes through the upper end of the interior of the furnace body 1 and is connected to the external exhaust fan.

[0026] like Figures 4 to 8As shown, in another embodiment of this utility model, first guide plates 5 are respectively provided on the front and rear sides of the upper end of the furnace body 1, and a first fan 7 is located between the first guide plates 5. Second guide plates 8 are respectively installed on the front and rear sides of the lower end of the furnace body 1, and a second fan 9 is located between the second guide plates 8. The lower end of the partition plate 210 is set in an inverted triangle shape. The upper surface of the sagger 4 is provided with guide grooves 207 at both ends. The length of the partition plate 210 decreases from the center of the pressure plate 209 to both sides, and the partition plate 210 in the middle is the longest. The length of the partition plate 210 is symmetrically arranged on both sides of the center line of the pressure plate 209. The lower surface of the sagger 4 is provided with locking grooves 201. Sealing plates 202 are respectively fitted inside the locking grooves 201. Several guide holes 204 are provided through the upper end of the locking grooves 201. The upper surface of the sealing plates 202 is divided into Several sealing rods 203 are installed, and the sealing rods 203 are respectively engaged and installed inside the guide hole 204. The upper end of the engagement groove 201 is provided with movable grooves 205 on both sides. Movable frames 206 are respectively engaged and installed inside the movable grooves 205. The lower end of the movable frames 206 is connected to the sealing plate 202. The interior of the furnace body 1 is provided with sliding grooves 214 on both sides. The sliding grooves 214 are respectively engaged and installed inside the sliding grooves 214. The two ends of the conveying roller 3 located in the middle of the lower surface of the sagger 4 are respectively connected to the sliding blocks 217. The lower ends of both sides of the furnace body 1 are respectively installed with second cylinders 218. The output end of the second cylinders 218 is connected to the sliding blocks 217. The interior of the sliding grooves 214 is provided with heat insulation grooves 215. Heat insulation plates 216 are respectively engaged and installed inside the heat insulation grooves 215. The heat insulation plates 216 are connected to the sliding blocks 217.

[0027] The first motor 6 and the second motor 10 respectively drive the first fan 7 at the upper end and the second fan 9 at the lower end of the furnace body 1 to rotate. At the same time, the first guide plate 5 at the upper end and the second guide plate 8 at the lower end inside the furnace body 1 cooperate to guide the airflow, so that the first fan 7 and the second fan 9 form a bidirectional airflow circulation. Then, the first guide plate 5 and the second guide plate 8 guide the airflow, so that the airflow distribution inside the furnace body 1 is more uniform, the temperature field is more balanced, and the material processing effect is more stable.

[0028] When the conveying roller 3 moves the sagger 4 to the designated position, the first cylinder 208 pushes the pressure plate 209 down, and the pressure plate 209 drives the partition plate 210 down. Then, the partition plate 210, which is the longest in the middle, first inserts into the gap of the sagger 4 along the guide groove 207 on the upper surface of the sagger 4, pushing the two saggers 4 outward. Then, as the pressure plate 209 continues to move down, the partition plates 210 on both sides, which are shorter in length, insert into the gap of the sagger 4, pushing the outermost sagger 4 further outward, so that a heat dissipation gap is formed between the saggers 4.

[0029] The inverted triangular lower end of the partition plate 210 cooperates with the guide groove 207, making the insertion process smoother and avoiding damage to the sagger 4. Then, a heat dissipation gap is formed between the saggers 4, which increases the airflow contact area on the surface of the sagger 4 and accelerates the heat transfer efficiency. The design of the partition plate 210 with the length decreasing from the center to both sides ensures that the saggers 4 in different positions can be pushed open evenly to form a reasonable heat dissipation spacing.

[0030] Then, after the pressure plate 209 is attached to the surface of the sagger 4, the second cylinder 218 drives the slider 217 to move down. The slider 217 drives the conveying roller 3 at the lower middle of the sagger 4 to move down. Then, the sealing plate 202 at the lower end of the sagger 4, due to its own weight, drives the sealing rod 203 to disengage from the guide hole 204 through the movable frame 206. Then, the external exhaust fan connects the first suction pipe 213 with the gas collection groove 211 and the suction hole 212 inside the pressure plate 209 to attract the gas inside the sagger 4. Then, the second suction pipe 11 attracts the gas in the furnace body 1. Then, the gas in the sagger 4 is attracted through the suction hole 212. Then, the airflow in the furnace body 1 enters the interior of the sagger 4 through the guide hole 204, forming a gas displacement to discharge the high-temperature gas in the sagger 4, further improving the overall cooling efficiency. Then, by attracting the gas in the furnace body 1, the high-temperature gas inside the furnace body 1 is discharged in time to avoid the high-temperature airflow from stagnating, reduce the internal temperature of the furnace body 1, and provide a good environment for subsequent cooling.

[0031] Filters are used to block materials and prevent them from being discharged into the outside world along with the airflow.

[0032] The working principle of this rapid cooling equipment for kilns:

[0033] In operation, the first motor 6 and the second motor 10 first drive the first fan 7 at the top and the second fan 9 at the bottom of the furnace body 1 to rotate, respectively. Simultaneously, the first guide plate 5 at the top and the second guide plate 8 at the bottom of the furnace body 1 work together to guide the airflow, allowing the first fan 7 and the second fan 9 to form a bidirectional airflow circulation. Then, the first guide plate 5 and the second guide plate 8 guide the airflow, making the airflow distribution within the furnace body 1 more uniform, improving the temperature field balance, and making the material processing effect more stable. Then, when the conveyor roller 3 moves the sagger 4 to the designated position, the first cylinder 208 pushes the pressure plate 209 downwards. The pressure plate 209 drives the partition plate 210 downwards. Then, the longest partition plate 210 in the middle first inserts into the gap between the sagger 4 along the guide groove 207 on the upper surface of the sagger 4, pushing the two saggers 4 outwards. Then, as the pressure plate 209 continues to move downwards, the shorter partition plates 210 on both sides insert into the gap between the saggers 4, further pushing the outermost sagger 4 outwards, forming a heat dissipation gap between the saggers 4. After the pressure plate 209 is attached to the surface of the sagger 4, the second cylinder 218 drives the slider 217 to move down. The slider 217 drives the conveying roller 3 at the lower middle of the sagger 4 to move down. Then, the sealing plate 202 at the lower end of the sagger 4, due to its own weight, drives the sealing rod 203 to disengage from the guide hole 204 through the movable frame 206. Then, the external exhaust fan connects the first suction pipe 213 with the gas collection groove 211 and the suction hole 212 inside the pressure plate 209 to draw in the gas inside the sagger 4. Then, the second suction pipe 11 draws in the gas inside the furnace body 1. Then, the gas inside the sagger 4 is drawn in through the suction hole 212. This allows the airflow inside the furnace body 1 to enter the interior of the sagger 4 through the guide hole 204, forming a gas displacement and expelling the high-temperature gas inside the sagger 4, further improving the overall cooling efficiency. Then, by drawing in the gas inside the furnace body 1, the high-temperature gas inside the furnace body 1 is discharged in time, avoiding the stagnation of high-temperature airflow, reducing the internal temperature of the furnace body 1, providing a good environment for subsequent cooling, and completing the cooling work.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
