Description

Technical Field

[0001] This utility model relates to the field of silicon carbide ceramic plate production technology, specifically a rapid cooling device for silicon carbide ceramic plates after sintering and forming. Background Technology

[0002] After the high-temperature sintering process, silicon carbide ceramic plates still retain high heat inside and on their surface. To avoid structural cracking, increased residual stress, or safety risks during handling caused by high temperatures, rapid, uniform, and controllable cooling is necessary. Existing technologies for cooling ceramic products mainly include natural cooling, forced air cooling with a single fan, and centralized cooling in a box-type cooling chamber.

[0003] In natural cooling methods, ceramic plates typically rely on gradual heat dissipation from their surroundings while remaining stationary. While this method offers the advantage of simple structure, the cooling rate is extremely slow, making it unsuitable for continuous industrial production. Furthermore, uneven cooling can easily lead to cracks or structural deformation due to excessive surface temperature differences.

[0004] Traditional forced-air cooling methods typically use a high-powered fan to blow cold air into the housing or conveyor belt area containing ceramic plates. However, this type of structure often only effectively cools certain areas, and the cold air cannot penetrate the stacked ceramic plates evenly, resulting in uneven cooling and long cooling times. Furthermore, this type of system is difficult to implement in-station sequential cooling, thus limiting production efficiency.

[0005] Another typical structure is the box-type centralized cooling chamber, which places a large number of ceramic plates into the cooling chamber and then circulates cold air through a refrigeration unit. However, due to the large volume of the box-type chamber and the complex internal circulation path of the cold air, problems such as airflow short-circuiting and insufficient cold air flow in some areas often occur; moreover, it cannot achieve independent cooling of individual or group-type ceramic plates. For working conditions that require frequent batch switching or continuous feeding, the box-type cooling chamber is difficult to adapt to the fast production cycle. In addition, the above structures generally use fixed chambers, lacking exchange and indexing mechanisms, and cannot realize the rotation of cooling units with the refrigeration airflow.

[0006] Furthermore, the existing cooling system's refrigeration chamber structure is mostly a simple straight-tube heat exchanger, resulting in low cooling efficiency and insufficient heat exchange path for airflow within a limited space. The airflow circulation pipes also lack external heat dissipation enhancement components, further contributing to the overall low efficiency of the refrigeration system. For applications requiring rapid and uniform cooling, such as cooling ceramic plates, existing structures struggle to achieve ideal cooling performance.

[0007] In view of this, this paper studies and improves the existing problems, and provides a rapid cooling device after the silicon carbide ceramic plate is sintered and formed, in order to solve the current problems and improve the practical value of the technology. Utility Model Content

[0008] This invention aims to solve the problems of long cooling time, uneven cooling, low refrigeration efficiency, and inability to achieve continuous cooling at multiple workstations in existing silicon carbide ceramic plate cooling methods. It proposes a rapid cooling device for silicon carbide ceramic plates after sintering and forming, which has a compact structure, a clear cooling path, and can realize multi-chamber indexing and sequential docking.

[0009] This invention utilizes a rotating wheel on the frame surface to align multiple mounting compartments sequentially with the interface of the circulating air duct at equal angles. Combined with a ducted fan driving airflow circulation, and the spiral cooling pipes and heat exchange mesh structure of the cooling compartment, this allows the ceramic plate to achieve efficient and uniform rapid cooling within its independent mounting compartment. The overall structure is suitable for continuous production processes and can significantly improve the cooling efficiency of the ceramic plate after sintering.

[0010] This invention includes a frame, a rotating wheel for indexing rotation, several bays, and a circulating air duct forming a closed cooling loop. The bays are mounted on the rotating wheel and sequentially connect to the ports of the circulating air duct as the wheel rotates, achieving multi-station sequential cooling. The circulating air duct includes a ducted fan, a cooling chamber, a return air duct, and a connecting pipe, forming a closed airflow circulation system. Ceramic plates are placed on mounting plates within the bays, where the cooling airflow carries away heat, achieving rapid cooling.

[0011] A rotating wheel is mounted on the surface of the frame, and several pods are evenly arranged along the circumference of the wheel. As the wheel rotates, the pods slide into contact with the interface flanges of the circulating air duct in sequence, achieving multi-station circulating cooling. The circulating air duct includes a ducted fan, a cooling compartment, a return air duct, and a connecting pipe. One end of the connecting pipe is connected to the cooling compartment, and both the cooling compartment and the return air duct have interface flanges that match the pods.

[0012] Specifically, it achieves rapid sealed connection between the pods and the circulating air duct, enabling multiple pods to complete the cooling operation sequentially according to the indexing cycle, thereby forming a continuous rapid cooling process.

[0013] In a preferred embodiment, the present invention may be further configured as follows: a spirally arranged refrigeration pipe is provided inside the refrigeration chamber, so that the airflow extends the heat exchange path inside the refrigeration chamber; heat exchange mesh is fixedly installed on the outside of the refrigeration chamber, and each heat exchange mesh has a grid-like structure so that the airflow can further dissipate heat when passing through the outside.

[0014] Specifically, by combining spiral refrigeration pipes with grid-like heat exchange fins, the cooling efficiency of the refrigeration chamber for airflow is improved, ensuring a stable temperature of the cold air entering the cabin.

[0015] In a preferred embodiment, the present invention may be further configured as follows: refrigerant is added inside the refrigeration pipe, and a compression refrigeration system is connected to the end of the refrigeration chamber, so that the refrigerant inside the refrigeration pipe forms a circulating flow mode to achieve a continuous cooling effect.

[0016] Specifically, it enables the refrigeration chamber to maintain a stable low temperature over a long period of time, thereby improving the operating efficiency and cooling speed of the entire cooling system.

[0017] In a preferred embodiment, the present invention may be further configured such that: the ducted fan drives the airflow to circulate along the path of "connecting pipe → cooling chamber → hanging chamber → return air pipe", so that the airflow directly contacts the ceramic plate inside the hanging chamber to complete rapid cooling.

[0018] Specifically, it forms a closed and efficient cooling airflow circuit, making the airflow directional and continuous, and improving cooling uniformity and control accuracy.

[0019] In a preferred embodiment, the present invention may be further configured such that: both the end of the refrigeration compartment and the return air duct are provided with interface flanges, and the hanging compartment is connected to the interface flanges by sliding under the drive of the rotating wheel, so as to achieve a quick sealing connection.

[0020] Specifically, this reduces docking time, improves the automated repositioning capability of the modules, and ensures the sealing and stability of the airflow channels.

[0021] In a preferred embodiment, the present invention may be further configured such that the surfaces of the ducted fan, the refrigeration chamber, the return air duct, and the connecting pipe are all provided with heat dissipation fin rings to increase the heat dissipation area.

[0022] Specifically, it enhances the heat dissipation performance of the circulating air duct, improves cooling efficiency, and ensures that the system can operate continuously and stably for a long time.

[0023] In a preferred embodiment, the present invention may be further configured such that: an indexing motor is mounted on the surface of the frame to drive the rotating wheel, and the indexing angle is completely consistent with the central angle of any adjacent bay, so that each bay can be precisely aligned with the refrigeration compartment and the return air duct.

[0024] Specifically, ensure that the docking position of the pods is accurate and reliable, so that the fractional cooling process can be carried out continuously and stably.

[0025] In a preferred embodiment, the present invention may be further configured such that: a plurality of mounting plates are provided in the hangar, the mounting plates are made of thermally conductive metal material, used to support silicon carbide ceramic plates and promote heat transfer, so that the ceramic plates can have more full contact with the cold air.

[0026] Specifically, it improves the uniformity of cooling of ceramic plates, making the cooling process faster, safer, and more stable.

[0027] The beneficial effects achieved by this utility model are as follows:

[0028] 1. In this utility model, by setting a rotating wheel on the frame and arranging several hanging compartments along the circumferential direction on the surface of the rotating wheel, each hanging compartment can be connected to the circulating air duct in sequence under the drive of the indexing motor; combined with the directional airflow circulation path formed by the duct fan, each hanging compartment can obtain a uniform, stable and controllable cooling airflow in an independent workstation, thereby realizing continuous and rapid cooling of silicon carbide ceramic plates, improving cooling efficiency and significantly shortening the production cycle.

[0029] 2. In this utility model, by setting spiral refrigeration pipes and heat exchange meshes fixed to the outer surface of the refrigeration chamber inside the refrigeration chamber, and setting finned ring structures in the refrigeration chamber, return air pipe and connecting pipe of the circulating air duct, the airflow can obtain higher heat exchange efficiency when flowing through the refrigeration zone. At the same time, the hanging chamber is sealed by the interface flange, so that the cooling airflow can be concentrated on the silicon carbide ceramic plate on the mounting plate inside the hanging chamber, improving the overall cooling effect and effectively reducing energy consumption; thereby achieving a rapid, uniform and stable cooling process, improving the cooling quality and the reliability of the device.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0039] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0040] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a rapid cooling device for silicon carbide ceramic plates after sintering and molding.

[0041] Combination Figures 1-5 As shown, this utility model provides a rapid cooling device for silicon carbide ceramic plates after sintering and molding, including a frame 100, hanging compartments 200, and a circulating air duct 300. The frame 100 supports the rotating wheel 110 and the hanging compartment 200 assembly. The rotating wheel 110 is rotatably mounted on the surface of the frame 100 via bearings or a rotating shaft structure. Several hanging compartments 200 are evenly arranged circumferentially on the outer circumferential surface of the rotating wheel 110, so that the open end of each hanging compartment 200 can sequentially correspond to the interface position of the circulating air duct 300 during the rotation of the rotating wheel 110.

[0042] like Figure 1 As shown, the circulating air duct 300 includes a ducted fan 310, a cooling compartment 320, a return air duct 330, and a connecting pipe 340. The two ends of the ducted fan 310 are connected to the return air duct 330 and the connecting pipe 340 respectively, and together they form a closed airflow loop for circulating cooling airflow inside the compartment 200.

[0043] One end of the connecting pipe 340 is connected to the refrigeration compartment 320. Both the refrigeration compartment 320 and the return air pipe 330 are provided with interface flanges at their far ends. The flange size matches the port of the hanging compartment 200, and is used to slide and engage with the hanging compartment 200 when the rotating wheel 110 rotates into position to achieve airflow communication.

[0044] In this embodiment, when the rotor 110 rotates, different pods 200 sequentially connect to the interface flange of the circulating air duct 300, thereby achieving sequential rapid cooling of multiple silicon carbide ceramic plates.

[0045] like Figure 2 and Figure 3 As shown, the interior of the refrigeration chamber 320 is provided with a spirally arranged refrigeration pipe 321. The refrigeration pipe 321 extends along the inner wall of the refrigeration chamber 320 in a spiral direction, so that the airflow can fully exchange heat with the refrigeration pipe 321 when it flows inside the refrigeration chamber 320.

[0046] Several heat exchange meshes 322 are fixedly installed on the outer surface of the refrigeration chamber 320. The heat exchange meshes 322 are arranged in a grid structure on the outer side wall of the refrigeration chamber 320 to enhance the heat dissipation capacity of the refrigeration chamber 320 and improve the heat exchange efficiency of the external air to the refrigeration system.

[0047] In a preferred embodiment, the refrigerant inside the refrigeration pipe 321 is filled with a refrigerant, such as Freon or other refrigerants suitable for closed refrigeration cycles.

[0048] like Figure 2 As shown, the end of the refrigeration chamber 320 is connected to a compression refrigeration system, including conventional refrigeration equipment such as a compressor, condenser and expansion valve, which is used to drive the refrigerant to circulate inside the refrigeration pipe 321 to achieve continuous cooling inside the refrigeration chamber 320.

[0049] like Figure 2 As shown, the ducted fan 310 is used to drive the circulating airflow, causing it to flow along a predetermined path. Driven by the ducted fan 310, the airflow sequentially passes through the connecting pipe 340, the refrigeration chamber 320, the hanging chamber 200, and the return air pipe 330 to form a closed loop.

[0050] In this process, the airflow is cooled by the cooling pipe 321 in the cooling chamber 320, and after entering the hanging chamber 200, it rapidly cools the ceramic plate. Then, it flows into the duct fan 310 through the return air pipe 330 to form a continuous cycle.

[0051] like Figure 1 and Figure 4 As shown, both the refrigeration compartment 320 and the return air duct 330 are equipped with interface flanges at their ends, and the size and shape of the interface flanges are matched with the flange structures at both ends of the hanging compartment 200.

[0052] When the rotor 110 drives the pod 200 to rotate, the two ends of the pod 200 can be aligned and slidably engaged with the interface flanges of the refrigeration compartment 320 and the return air duct 330, respectively, so that the pod 200 can be reliably connected to the circulating air duct 300, and the cooling airflow can enter the interior of the pod 200.

[0053] like Figure 1 and Figure 2 As shown, in order to improve the heat dissipation performance of the circulating air duct 300, the outer surfaces of the duct fan 310, the cooling chamber 320, the return air duct 330, and the connecting pipe 340 are all provided with several finned rings.

[0054] Finned rings are used to increase the heat dissipation area of ​​the outer surface, allowing the waste heat of the circulating airflow to be transferred to the external environment more quickly, thereby improving cooling efficiency.

[0055] like Figure 1 and Figure 4 As shown, an indexing motor is installed on the frame 100 to drive the rotary wheel 110 to rotate in indexing order.

[0056] The indexing motor drives the rotating wheel 110 to rotate by a fixed angle each time. This indexing angle is equal to the central angle of the adjacent pod 200, so that each pod 200 can accurately correspond to the interface position of the circulating air duct 300 after rotation.

[0057] like Figure 5 As shown, the interior of the hangar 200 is equipped with several mounting plates 210. The mounting plates 210 are made of thermally conductive metal and have a horizontally layered structure, which allows the silicon carbide ceramic plates to be stably placed on the mounting plates 210.

[0058] The pod 200 comes into contact with the cooling airflow, allowing the airflow to pass sequentially through the gaps between the mounting plates 210, thereby directly acting on the surface of the ceramic plate and achieving rapid and uniform cooling.

[0059] Working principle and usage process of this utility model:

[0060] After the silicon carbide ceramic plates are sintered and formed, they are placed sequentially on the mounting plates 210 inside each hanging compartment 200. Then, the indexing motor drives the rotating wheel 110 to rotate gradually at equal intervals, so that the hanging compartment 200 slides and connects with the interface flanges of the cooling compartment 320 and the return air duct 330 to form a sealed connection. After the duct fan 310 starts, it pushes the airflow to circulate in the order of connecting pipe 340 → cooling compartment 320 → hanging compartment 200 → return air duct 330. The airflow fully exchanges heat with the spiral cooling pipe 321 and heat exchange mesh 322 in the cooling compartment 320 to achieve cooling. After entering the hanging compartment 200, it comes into direct contact with the silicon carbide ceramic plates carried on the mounting plates 210, quickly removing the heat from the surface of the ceramic plates. As the rotating wheel 110 continues to index, multiple hanging compartments 200 circulate sequentially between the cooling zone, the return air zone and the waiting zone, realizing continuous, multi-station, efficient and rapid cooling, so that the sintered ceramic plates reach the safe transfer temperature in a short time, improving cooling efficiency and overall production cycle.
