Description

Technical Field

[0001] This utility model relates to the field of furnace cooling technology, and in particular to a cooling device for a continuous firing kiln and a kiln using the same. Background Technology

[0002] In recent years, there has been an increasing trend in the firing process of battery materials to increase the total length of roller kilns in order to improve production capacity. However, with the increase in kiln length, the serpentine arrangement of saggers during exiting the kiln due to the jumping of the drive rollers also increases, which reduces the stability of the transmission system. As a result, saggers that are transported in parallel before entering the kiln are prone to disordered arrangement after exiting the kiln.

[0003] The length of the heating zone in the kiln cannot be changed due to product process requirements. To avoid the overall kiln length becoming too long, the length of the cooling zone must be shortened to simultaneously meet both product process requirements and the need to reduce the overall kiln length. However, shortening the cooling zone significantly increases the required cooling rate. Utility Model Content

[0036] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] Please refer to Figures 1-6 This utility model provides a cooling device for a continuous firing kiln, including a base 1, a cooling chamber 2, a conveying roller group 3, a conveying drive device 4, an air-cooling component 5, and a water-cooling component 6.

[0039] The cooling chamber 2 is installed on the base 1. The cooling chamber 2 has a receiving cavity 20. The conveying roller group 3 is disposed in the receiving cavity 20. The conveying drive device 4 is disposed on one side of the conveying direction of the base 1. The conveying drive device 4 is drivenly connected to the conveying roller group 3 and is used to drive the conveying roller group 3 to convey the sagger 8.

[0040] The air-cooled assembly 5 includes a cold air duct 51 and a cold air fan 52; the cold air duct 51 includes a horizontal air duct 511, a first vertical air duct 512, a second vertical air duct 513, a first air outlet duct 514, and a second air outlet duct 515.

[0041] The horizontal air duct 511 is disposed at the top of the receiving cavity 20, the first vertical air duct 512 is disposed on the inner wall of the receiving cavity 20 on one side along the conveying direction, and the first vertical air duct 512 is disposed on the other side of the inner wall of the receiving cavity 20; the first air outlet duct 514 and the second air outlet duct 515 are respectively disposed at the bottom of the receiving cavity 20; the first end of the first vertical air duct 512 is connected to the first end of the horizontal air duct 511, and the second end of the first vertical air duct 512 is connected to the first air outlet duct 514, forming the first air duct 501; the first end of the second vertical air duct 513 is connected to the second end of the horizontal air duct 511, and the second end of the second vertical air duct 513 is connected to the second air outlet duct 515, forming the second air duct 502;

[0042] The horizontal air duct 511 is provided with a return air inlet 503, and the first air outlet duct 514 and the second air outlet duct 515 are respectively provided with air outlets 504; the cold air fan 52 is installed on the top of the cooling chamber 2, and the air outlet of the cold air fan 52 is located in the horizontal air duct 511.

[0043] The cooling device for the continuous firing kiln is equipped with a cold air duct 51 and a cold air fan 52. The cold air fan 52 delivers cold air to the cold air duct 51, and the cold air is discharged through the air outlet 504 of the cold air duct 51. Since the first air outlet 514 and the second air outlet 515 are located at the bottom of the accommodating cavity 20, and the conveyor roller assembly 3 is located above the air outlet 504, the cold air flows from the bottom of the conveyor roller assembly to the top of the accommodating cavity 20, thereby achieving the interaction between the cold air and the conveyor rollers. The heat exchange between group 3 and the sagger 8 causes the conveyor roller group 3 and the sagger 8 to cool down from bottom to top. After the heat exchange, the cold air becomes hot air, and the hot air moves upward and passes through the water cooling device 6 and gradually cools down. The cold air fan 52 draws the cooled air back to the horizontal air duct 511 of the cold air duct 51 through the return air port 503, so that the cold air fan 52 can transport the cooled air back to the first air duct 501 / second air duct 502 to achieve circulating air cooling.

[0044] The above structure can effectively prevent the conveyor roller group 3 and the sagger 8 from deforming due to long-term high temperature. This not only improves the service life of the conveyor roller group 3 and the sagger 8 and avoids the problem of frequent production stoppages for maintenance, thus improving production efficiency, but also avoids the problem of the conveyor roller group 3 and the sagger 8 being unable to transport products in parallel due to deformation, thereby improving production quality.

[0045] In one embodiment of this invention, the water-cooling assembly 6 consists of a finned tube, an inlet pipe, and an outlet pipe. Cold water enters through the inlet pipe and undergoes heat exchange within the finned tube. After heat exchange, the cold water transforms into hot water, which then flows out through the outlet pipe. This structure allows for cooling of the heated gas after heat exchange with the water-cooling assembly 6, ensuring that the gas is cooled before entering the horizontal air duct 511 through the return air inlet 503, thereby improving the cooling efficiency of the cooling device.

[0046] Specifically, the horizontal air duct 511 is provided with a plurality of first air guide plates 505 at both ends, and the first vertical air duct 512 and the second vertical air duct 513 are provided with a plurality of second air guide plates 506; the first air guide plates 505 are connected to the corresponding second air guide plates 506, and the first air guide plates 505, the second air guide plates 506 and the accommodating cavity 20 cooperate to divide the first air duct 501 / second air duct 502 into a plurality of air outlet channels.

[0047] By adopting the above structure, the first air duct 501 / second air duct 502 is divided into several air outlet channels by the cooperation of the first air guide plate 505, the second air guide plate 506 and the accommodating cavity 20. The cold air delivered by the cold air fan 52 can be evenly delivered to different air outlet channels, preventing the air volume at different positions in the first air duct 501 / second air duct 502 from being different due to the limitation of the shape of the first air duct 501 / second air duct 502, which would lead to uneven cooling at different positions in the accommodating cavity 20. This avoids the problem of deformation of the sagger 8 due to uneven cooling.

[0048] In one specific embodiment of this utility model, the first air guide plate 505 includes a front air guide arc plate and a rear air guide arc plate. The front and rear air guide arc plates are symmetrically arranged at both ends of the horizontal air duct 511. The front air guide arc plate is located at one end of the cooling chamber 2 inlet, and the rear air guide arc plate is located at one end of the cooling chamber 2 outlet. The front air guide arc plate bends towards the cooling chamber 2 outlet, and the rear air guide arc plate bends towards the cooling chamber 2 inlet. This structure reduces the disturbance and turbulence of the airflow caused by the first air guide plate 505, thus reducing gas resistance. Compared to a straight air guide plate, the arc design effectively reduces airflow resistance, reduces energy loss, and improves airflow stability. Furthermore, it allows the airflow to be evenly distributed to the desired area, helping to optimize heat exchange, ensuring uniform distribution of cool air, and avoiding localized uneven heating and cooling.

[0049] Specifically, both the first air outlet duct 514 and the second air outlet duct 515 are provided with a first air guide duct 507 and a second air guide duct 508; the first air guide duct 507 is located above the second air guide duct 508; the second air guide duct 508 is located above the first air outlet duct 514 / second air outlet duct 515.

[0050] The first ends of the first air guide duct 507 and the second air guide duct 508 are located at the air outlet ends of the first air duct 501 / second air duct 502; the second ends of the first air guide duct 507 and the second air guide duct 508 are located below the air outlet 504; the length of the first air guide duct 507 is less than the length of the second air guide duct 508, and the length of the second air guide duct 508 is less than the length of the first air outlet duct 514 / second air duct 502, so that the air outlet 504 is divided into three air outlet areas.

[0051] With the above structure, the air outlet 504 is divided into three air outlet zones by the first air guide duct 507 and the second air guide duct 508, so that the airflow is evenly distributed to the required area. The position of the sagger 8 can be adjusted according to the position of the air outlet zone, so that the position of the sagger 8 corresponds directly to the position of the air outlet zone. After the cold air is discharged from the air outlet 504, it directly contacts the sagger 8, further optimizing the cooling effect. Moreover, the first air guide duct 507 and the second air guide duct 508 pour part of the cold air into the corresponding air outlet zone to ensure the even distribution of cold air and avoid local overheating or overcooling.

[0052] Specifically, it also includes a gate assembly 7, which includes a lifting drive device 71 and a lifting gate 72; the lifting gate 72 is installed at the entrance and exit of the cooling chamber 2; the lifting drive device 71 is located at the top of the cooling chamber 2 and is drivenly connected to the lifting gate 72 to drive the lifting gate 72 to move up and down.

[0053] The cooling chamber 2 has an inlet at one end along the conveying direction and an outlet at the other end along the conveying direction; the inlet and outlet are respectively connected to the accommodating cavity 20.

[0054] In one specific embodiment of this utility model, the lifting drive device 71 is a cylinder. When the sagger 8 containing the product is conveyed to the cooling chamber 2 by the conveying roller group 3, the lifting drive device 71 drives the lifting gate 72 at the entrance of the cooling chamber 2 to open. The sagger 8 quickly passes through the lifting gate and enters the cooling chamber 2. Then the lifting gate 72 closes.

[0055] With the above structure, when the sagger 8 containing the product enters the accommodating cavity 20, the lifting gate 72 at the inlet closes, and the cooling outlet end is connected to the outlet displacement chamber 104, thereby forming a relatively sealed space in the cooling chamber 2. The cold air fan 52 of the air-cooling component 5 is started, so that the gas in the accommodating cavity 20 circulates rapidly between the accommodating cavity 20 and the cold air duct 51, which is more conducive to heat dissipation of the sagger 8 containing the product.

[0056] Furthermore, it also includes an inlet photoelectric sensor 201; the inlet photoelectric sensor 201 is disposed on both sides of the inlet end of the cooling chamber 2, and the detection end of the inlet photoelectric sensor 201 passes through the cooling chamber 2 and enters the receiving cavity 20; the inlet photoelectric sensor 201 is electrically connected to the lifting drive device 71, and when the inlet photoelectric sensor 201 detects that the sagger 8 has passed by, it causes the lifting drive device 71 to drive the lifting gate 72 to move upward.

[0057] The inlet-end photoelectric sensor 201 can refer to the photoelectric sensors of existing kilns. The inlet-end photoelectric sensor 201 detects whether the sagger 8 has entered the receiving cavity 20, thereby determining whether the lifting gate 72 needs to be lowered. By controlling the raising and lowering of the lifting gate 72, the inlet of the cooling chamber 2 is opened or closed. When the sagger 8 is detected, the inlet-end photoelectric sensor 201 sends an electrical signal to the lifting drive device 71, causing the lifting drive device 71 to drive the lifting gate 72 upwards, allowing the sagger 8 to enter the cooling chamber 2.

[0058] Furthermore, the conveying drive device 4 includes a bracket 41, a fast motor 42 and a slow motor 43. The bracket 41 is disposed on one side of the base 1 in the conveying direction. The fast motor 42 and the slow motor 43 are respectively disposed on the bracket 41. The fast motor 42 and the slow motor 43 are respectively connected to the conveying roller group 3 for driving.

[0059] The cooling chamber 2 is also equipped with an outlet photoelectric sensor 202; the outlet photoelectric sensor 202 is located on both sides of the outlet end of the cooling chamber 2, and the detection end of the outlet photoelectric sensor 202 passes through the cooling chamber 2 and enters the receiving cavity 20; the inlet photoelectric sensor 201 is electrically connected to the fast motor 42; the outlet photoelectric sensor 202 is electrically connected to the lifting drive device 71 and the slow motor 43 respectively;

[0060] When the inlet photoelectric sensor 201 detects the sagger 8, the lifting drive device 71 drives the lifting gate 72 to move upward, and the fast motor 42 drives the conveying roller group 3 to quickly convey the sagger 8 through the lifting gate 72, thus opening the inlet of the cooling chamber 2. When the outlet photoelectric sensor 202 detects the sagger 8, the lifting drive device 71 drives the lifting gate 72 to move downward, thus closing the inlet of the cooling chamber 2, thereby forming a relatively sealed space in the cooling chamber. The slow motor 43 drives the conveying roller group 3 to slowly convey the sagger 8, allowing the sagger 8 to be fully cooled in the cooling chamber, thereby improving the cooling efficiency.

[0061] Specifically, the conveying roller group 3 includes a plurality of conveying rollers, the two ends of which are rotatably mounted in the accommodating cavity 20, and the conveying rollers are connected to the conveying drive device 4 in a transmission manner;

[0062] It also includes a column assembly 9, which includes an upright baffle 91 and an adjusting lifting device 92; the adjusting lifting device 92 is disposed at one end of the receiving cavity 20 near the inlet, and the adjusting lifting device 92 is drivenly connected to the upright baffle 91, so that the upright baffle 91 extends or retracts from the gap between two of the conveying rollers.

[0063] In one embodiment of this utility model, the conveying roller group 3 consists of multiple rotatable conveying rollers. One end of each conveying roller passes through a first vertical air duct 512 and is rotatably coupled to the outer wall of the cooling chamber 2. The other end of each conveying roller passes through a second vertical air duct 513 and is rotatably coupled to the other outer wall of the cooling chamber 2. A conveying drive device 4 is connected to the conveying rollers via a transmission chain. The conveying drive device 4 drives its output end to rotate, thereby causing the transmission chain to drive the multiple conveying rollers to rotate. The multiple conveying rollers are driven by the same motor, thereby achieving synchronous movement and synchronous stopping, ensuring that the multiple conveying rollers are in a synchronously stopped state during cooling, and ensuring operational stability.

[0064] Please refer to Figure 6 The present invention also provides a kiln, which includes an inlet replacement chamber 101, a heating belt 102, a cooling belt 103 and an outlet replacement chamber 104 connected in sequence. The cooling belt 103 is provided with the cooling device for continuous firing kiln described above.

[0065] With the above structure, during operation, the conveying drive device 4 drives the conveying roller group inside the kiln body to rotate, so that the conveying roller group conveys the product. The product passes through the inlet replacement chamber 101, the heating belt 102, the cooling belt 103 and the outlet replacement chamber 104 in sequence, and is cooled in the cooling belt 103.

[0066] The cooling belt 103 is equipped with the aforementioned cooling device for continuous firing kiln, which cools the conveyor roller group 3 and sagger 8 of the cooling belt 103 in the form of circulating air cooling, which can effectively reduce the temperature of sagger 8 and prevent the conveyor roller group 3 from deforming due to long-term high temperature.

[0067] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
