Description

Technical Field

[0001] This utility model relates to a drying oven, and more specifically, to a vacuum-sealed drying oven. Background Technology

[0002] Traditional drying ovens primarily focus on heating and drying items to remove moisture, offering relatively limited functionality. In sample processing scenarios requiring temperature sensitivity, rapid cooling, and a consistently dry environment, traditional drying ovens fall short. Utilizing a vacuum environment lowers the boiling point of water, allowing samples to dry rapidly at lower temperatures while preventing oxidation and contamination from atmospheric oxygen. However, in a vacuum, convective heat transfer is virtually nonexistent, resulting in a very slow cooling rate and prolonged cooling processes. Furthermore, how to preserve dried and cooled samples in a vacuum environment to minimize oxidation and contamination, as well as ease of transport, are also crucial considerations.

[0003] For example, Chinese Patent Publication No. CN117404878A, published on May 24, 2024, entitled "A Method and Apparatus for Rapid Heating, Drying, and Vacuum Cooling of Lithium Battery Cells," discloses a rapid heating, drying, and vacuum cooling apparatus, including a vacuum drying chamber and a vacuum cooling chamber, with a vacuum partition and conveying channel between them. A lifting mechanism adjusts the position of the material rack to achieve stacked storage of the processed materials. The materials are then subjected to pressurized contact heating and cooling, and the two processes of vacuum heating and drying are performed continuously and seamlessly, effectively improving the drying and cooling speed of lithium battery cells in a vacuum environment, ensuring the quality of drying and cooling processing, and enabling uninterrupted material transport, thus improving production efficiency. However, in this solution, the battery cells can only be slowly heated by the heater, failing to achieve rapid heating, resulting in low packaging efficiency and the inability to perform vacuum packaging. Furthermore, samples are prone to moisture re-entry. Utility Model Content

[0004] This invention overcomes the problems of low drying and packaging efficiency and easy moisture re-entry of dried products by providing a vacuum sealing drying oven. This solution can improve the drying and packaging efficiency of samples, and at the same time, vacuum packaging the samples achieves a good sealing effect.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a vacuum sealing drying oven, including a cooling chamber and drying chambers symmetrically arranged on both sides of the cooling chamber. Material transfer components are installed in both the drying chamber and the cooling chamber. A cooling platform and a sealing bottom cover are provided in the cooling chamber. A lifting device is provided at the top of the cooling chamber, and the telescopic end of the lifting device is equipped with a sealing container corresponding to the sealing bottom cover. In this solution, the drying chamber can rapidly heat and dry the sample, and the cooling chamber can cool and de-cool the dried sample. The combination of vacuum drying chambers on the left and right sides and a vacuum cooling chamber in the middle allows for continuous drying and cooling processes, improving overall work efficiency. Simultaneously, the sealing container and sealing bottom cover can seal the sample internally, achieving vacuum sealing, allowing the sample to be stored in a vacuum environment for a long time to avoid contamination, and also making it convenient to carry.

[0006] Preferably, the drying chamber is equipped with a heating stage, which has a heating component. The transfer component extends horizontally through the heating stage and into the drying chamber near the cooling chamber. The heating component heats the sample on the heating stage, and the transfer component transports the sample onto and from the heating stage to a transfer rail for further transfer into the cooling chamber.

[0007] Preferably, a gate valve is provided between the drying chamber and the cooling chamber. The gate valve can separate the drying chamber and the cooling chamber, or form a channel between them, thus forming an integral vacuum chamber while allowing the three chambers to independently maintain the required atmospheric or vacuum environment.

[0008] Preferably, the heating stage is also equipped with a temperature sensor. The temperature sensor on the heating stage can detect the temperature on the heating stage and provide real-time feedback on the heating temperature, thus providing a good heating effect for the sample.

[0009] Preferably, the cooling stage is equipped with a cooling system, which includes several interconnected cooling water pipes. Water cooling on the cooling stage allows for rapid cooling of the sample.

[0010] Preferably, a sealing seat is provided at the top of the cooling chamber, and the lifting device is fixed to the sealing seat. The lifting device includes a telescopic rod, the telescopic end of which is elastically connected to a pressure plate. The encapsulation container is detachably connected to the bottom of the pressure plate. The lifting device is fixed to the top of the cooling chamber, and the telescopic rod on the lifting device can extend and retract effectively, thereby covering the sample with the encapsulation container on the pressure plate from above, achieving a seal. The elastic connection between the pressure plate and the telescopic rod provides a buffering effect when the encapsulation container contacts the bottom cover, preventing damage to the encapsulation container and the bottom cover, thus ensuring a proper seal.

[0011] Preferably, a sealing component is provided between the packaging container and the packaging bottom cover. This sealing component creates a sealed space inside the packaging container. Once the vacuum environment in the cooling chamber is eliminated, external air pressure can press the packaging container firmly onto the packaging bottom cover, facilitating the packaging operation.

[0012] Preferably, the cooling chamber is also equipped with a thermometer. The thermometer can monitor the temperature inside the cooling chamber in real time, so as to understand the cooling status of the sample inside the cooling chamber.

[0013] Preferably, a transfer track is provided between the drying chamber and the cooling chamber. The transfer track can transport the dried sample in the drying chamber to the cooling chamber for cooling.

[0014] Preferably, the telescopic rod is slidably and sealingly connected to the sealing seat. The telescopic rod must maintain a sealed connection with the sealing seat during lifting and lowering to ensure a vacuum effect within the cooling chamber.

[0015] Compared with the prior art, the beneficial effects of this utility model are: (1) The equipment includes a vacuum drying chamber and a vacuum cooling chamber, which are separated by a slide valve. This facilitates the transfer of samples from the vacuum drying chamber to the vacuum cooling chamber and provides the vacuum environment required by the vacuum drying chamber and the vacuum cooling chamber respectively; (2) The temperature of the heating platform and the cooling platform is precisely controlled by the temperature sensor to achieve rapid heating and cooling, which can reduce the time spent on preheating, cooling and other processes and improve the overall experimental efficiency; (3) Samples treated by the drying and cooling process can be vacuum sealed in a vacuum environment to effectively isolate the outside air, water vapor and other substances, and prevent the dried samples from being damp and oxidized again during subsequent storage and transportation.

[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1: As Figures 1 to 3 The vacuum-sealed drying chamber shown includes a drying chamber 2 and a cooling chamber 1. Two drying chambers 2 are provided and symmetrically arranged on both sides of the cooling chamber 1. A gate valve 10 is provided between the cooling chamber 1 and the two drying chambers 2. A heating platform 8 and a transfer assembly 3 are provided in the drying chamber 2. A feed inlet 19 is provided on the side of the drying chamber 2 away from the cooling chamber 1. The transfer assembly 3 extends from the feed inlet 19 to the side of the heating platform 8 near the cooling chamber 1. The sample to be heated can be transported to the heating platform 8 of the drying chamber 2 through the transfer assembly 3, and the heated sample can be further transferred to the location of the cooling chamber 1. Cooling chamber 1 contains a cooling platform 4. A lifting device 6 is positioned directly above the cooling platform 4, controlling the vertical movement of a telescopic rod 14. A sealing container 7 is located at the bottom of the telescopic rod 14, and a sealing bottom cover 5 is mounted on the cooling platform 4. When a sample is transported from drying chamber 2 to the cooling platform 4 in cooling chamber 1, the lifting device 6 controls the sealing container 7 on the telescopic rod 14 to seal tightly against the sealing bottom cover 5 on the cooling platform 4, thus achieving cooling and sealing. In this design, both cooling chamber 1 and drying chamber 2 operate under vacuum. This vacuum environment allows for sample sealing, effectively isolating the sample from external air and moisture, preventing the dried sample from becoming damp or oxidized again during subsequent storage and transportation. Since the heating and drying process is relatively longer than the cooling and sealing process, configuring two drying chambers 2 and one cooling chamber 1 allows for continuous drying and cooling processes, improving overall work efficiency.

[0022] In this scheme, the structures inside the two drying chambers 2 are the same. Therefore, in this embodiment, only the drying chamber 2 and the cooling chamber 1 on the left side of the figure are described.

[0023] A heating element 9 is installed at the heating stage 8 inside the drying chamber 2. The heating element 9 can use upper and lower layer infrared baking heating or traditional lower layer electric heating. Specifically, the heating temperature range is 0℃ to 400℃. A temperature sensor 11 is installed on the heating stage 8 to provide real-time feedback on the temperature of the sample on the heating stage 8. After reaching the set temperature, it can also continuously maintain the current temperature.

[0024] A preparation platform 20 is also provided on the side of the drying chamber 2 away from the cooling chamber 1. The preparation platform 20 can hold the sample to be heated and dried. The sample is placed in a glass container 21, and the sample on the preparation platform 20 can be pushed onto the heating platform 8 by the transfer component 3. The heating platform 8 is heated to the set temperature by the temperature control system (heating component 9), and then the transfer component 3 transfers the sample to the heating platform 8 to achieve rapid heating and drying of the sample.

[0025] The slide gate valve 10 between the drying chamber 2 and the cooling chamber 1 is electrically controlled. Specifically, a transfer track 18 is also provided between the drying chamber 2 and the cooling chamber 1. The transfer track 18 consists of two sections: one section overlaps the heating platform 8 in the drying chamber 2, and the other section overlaps the cooling platform 8 in the cooling chamber 1. After the sample is heated and dried, the glass container 21 containing the sample is pushed onto the transfer track 18 in the drying chamber 2 by the transfer assembly 3. A position sensor (not shown in the figure) is also provided on the transfer track 18. The position sensor can monitor the position of the sample in real time. When the sample approaches the connection between the cooling chamber 1 and the drying chamber 2, the electrically controlled slide gate valve 10 will open, and the sample will be further transferred to the transfer track 18 in the cooling chamber 1, and finally reach the cooling platform 4 in the cooling chamber 1 for cooling and sealing.

[0026] It should be noted that the slide gate valve 10, cooling chamber 1, and drying chamber 2 are all sealed. The two end faces of the slide gate valve 10 are respectively sealed to the outlet of drying chamber 2 and the inlet of cooling chamber 1. The slide plate on the slide gate valve 10 slides and seals against the valve body, allowing the slide plate to move up and down on the valve body, thus opening or closing the passage between drying chamber 2 and cooling chamber 1. The slide gate valve 10 is controlled by an external controller and features vacuum isolation and a horizontal conveying channel. Drying chamber 2 and cooling chamber 1 each have their own vacuum systems consisting of extraction valves, extraction pipes, venting valves, and vacuum pumps, capable of achieving the vacuum environment required for the process. Installing two electric slide gate valves 10 can form an integrated vacuum chamber, providing a channel for sample transfer, while also allowing the three chambers to independently maintain the required atmospheric or vacuum environment.

[0027] A sealing base cover 5 is installed on the cooling platform 4 inside the cooling chamber 1. The sealing base cover 5 is located between the two left and right transfer tracks 18, and the height of the upper surface of the sealing base cover 5 is not higher than the height of the upper surface of the transfer track 18. This ensures that the glass container 21 containing the sample is transported to the sealing base cover 5. A sealing seat 13 is installed at the top of the cooling chamber 1. The sealing seat 13 is an integral structure of the top of the drying chamber 2. A lifting device 6 is installed on the sealing seat 13. The lifting device 6 includes a drive device 22, a telescopic rod 14, and a pressure plate 15. The drive device 22 is located outside the cooling chamber 1. The telescopic rod 14 slides on the sealing seat 13, which not only enables the telescopic rod 14 to move up and down but also ensures the vacuum environment inside the cooling chamber 1. A pressure plate 15 is installed at the bottom of the telescopic rod 14. The pressure plate 15 and the bottom of the telescopic rod 14 are connected by an elastic element 23. A sealing container 7 can also be detachably connected to the bottom of the pressure plate 15. The sealing container 7 can be fixed to the pressure plate 15 by a snap-fit ​​method. The sealing tank 7 is located directly on the cooling platform 4.

[0028] After the glass container 21 containing the sample enters the cooling platform 4, the lifting device 6 starts working, and the drive device 22 drives the telescopic rod 14 to move downward, bringing the sealing container 7 at the bottom of the pressure plate 15 into contact with the sealing bottom cover 5 on the cooling platform 4. The pressure plate 15 and the telescopic rod 14 are elastically connected, providing a buffering effect when the sealing container 7 contacts the sealing bottom cover 5, preventing damage to both and compromising the seal. Once the sealing container 7 is tightly sealed with the sealing bottom cover 5 on the cooling platform 4, the vent valve of the cooling chamber 1 is opened. Under atmospheric pressure, the sealing container 7 and the sealing bottom cover 5 are firmly sealed, creating a vacuum environment inside, thus completing the vacuum sealing process. Samples treated with the drying and cooling process can be stored in the container in a vacuum environment for a long time to avoid contamination and are also easy to carry.

[0029] It should be noted that the bottom of the encapsulation container 7 is provided with an annular wing plate structure forming a sealing end. A sealing assembly 16, including a sealing ring, is provided between the sealing end of the encapsulation container 7 and the bottom cover 5. Specifically, the sealing ring 16 can be provided on the bottom cover 5 or on the sealing end of the bottom of the encapsulation container 7. Since the surface area of ​​the bottom cover 5 is larger than the surface area of ​​the sealing end of the encapsulation container 7, it is preferable to provide the sealing ring on the sealing end to ensure an effective sealing fit between the encapsulation container 7 and the bottom cover 5. Of course, the sample on the cooling platform 4 can be cooled before encapsulation or encapsulated before cooling.

[0030] The working principle of this scheme is as follows: When the drying chamber 2 is working, the gate valve 10 between the drying chamber 2 and the cooling chamber 1 needs to be closed, and the vacuum pump needs to be started to evacuate the drying chamber 2; when the cooling chamber 1 is working, the gate valves 10 on both sides also need to be closed, and the vacuum pump needs to be started to evacuate the cooling chamber 1; when it is necessary to transfer the sample from the drying chamber 2 to the cooling chamber 1, the gate valve 10 is opened, and the vacuum degree of the drying chamber 2 is balanced in the two chambers through the vacuum isolation and transfer channel of the gate valve 10; after the sealing is completed, the vent valve of the cooling chamber 1 is opened, and finally the container of the sealed sample is taken out from the side door of the cooling chamber 1.

[0031] Example 2: Figures 1 to 3 The vacuum-sealed drying chamber shown includes a drying chamber 2 and a cooling chamber 1. Two drying chambers 2 are provided and symmetrically arranged on both sides of the cooling chamber 1. A gate valve 10 is provided between the cooling chamber 1 and the two drying chambers 2. A heating platform 8 and a transfer assembly 3 are provided in the drying chamber 2. A feed inlet 19 is provided on the side of the drying chamber 2 away from the cooling chamber 1. The transfer assembly 3 extends from the feed inlet 19 to the side of the heating platform 8 near the cooling chamber 1. The sample to be heated can be transported to the heating platform 8 of the drying chamber 2 through the transfer assembly 3, and the heated sample can be further transferred to the location of the cooling chamber 1. Cooling chamber 1 contains a cooling platform 4. A lifting device 6 is positioned directly above the cooling platform 4, controlling the vertical movement of a telescopic rod 14. A sealing container 7 is located at the bottom of the telescopic rod 14, and a sealing bottom cover 5 is mounted on the cooling platform 4. When a sample is transported from drying chamber 2 to the cooling platform 4 in cooling chamber 1, the lifting device 6 controls the sealing container 7 on the telescopic rod 14 to seal tightly against the sealing bottom cover 5 on the cooling platform 4, thus achieving cooling and sealing. In this design, both cooling chamber 1 and drying chamber 2 operate under vacuum. This vacuum environment allows for sample sealing, effectively isolating the sample from external air and moisture, preventing the dried sample from becoming damp or oxidized again during subsequent storage and transportation. Since the heating and drying process is relatively longer than the cooling and sealing process, configuring two drying chambers 2 and one cooling chamber 1 allows for continuous drying and cooling processes, improving overall work efficiency.

[0032] In this scheme, the structures inside the two drying chambers 2 are the same. Therefore, in this embodiment, only the drying chamber 2 and the cooling chamber 1 on the left side of the figure are described.

[0033] A heating element 9 is installed at the heating stage 8 inside the drying chamber 2. The heating element 9 can use upper and lower layer infrared baking heating or traditional lower layer electric heating. Specifically, the heating temperature range is 0℃ to 400℃. A temperature sensor 11 is installed on the heating stage 8 to provide real-time feedback on the temperature of the sample on the heating stage 8. After reaching the set temperature, it can also continuously maintain the current temperature.

[0034] A preparation platform 20 is also provided on the side of the drying chamber 2 away from the cooling chamber 1. The preparation platform 20 can hold the sample to be heated and dried. The sample is placed in a glass container 21, and the sample on the preparation platform 20 can be pushed onto the heating platform 8 by the transfer component 3. The heating platform 8 is heated to the set temperature by the temperature control system (heating component 9), and then the transfer component 3 transfers the sample to the heating platform 8 to achieve rapid heating and drying of the sample.

[0035] The slide gate valve 10 between the drying chamber 2 and the cooling chamber 1 is electrically controlled. Specifically, a transfer track 18 is also provided between the drying chamber 2 and the cooling chamber 1. The transfer track 18 consists of two sections: one section overlaps the heating platform 8 in the drying chamber 2, and the other section overlaps the cooling platform 8 in the cooling chamber 1. After the sample is heated and dried, the glass container 21 containing the sample is pushed onto the transfer track 18 in the drying chamber 2 by the transfer assembly 3. A position sensor (not shown in the figure) is also provided on the transfer track 18. The position sensor can monitor the position of the sample in real time. When the sample approaches the connection between the cooling chamber 1 and the drying chamber 2, the electrically controlled slide gate valve 10 will open, and the sample will be further transferred to the transfer track 18 in the cooling chamber 1, and finally reach the cooling platform 4 in the cooling chamber 1 for cooling and sealing.

[0036] It should be noted that the slide gate valve 10, cooling chamber 1, and drying chamber 2 are all sealed. The two end faces of the slide gate valve 10 are respectively sealed to the outlet of drying chamber 2 and the inlet of cooling chamber 1. The slide plate on the slide gate valve 10 slides and seals against the valve body, allowing the slide plate to move up and down on the valve body, thus opening or closing the passage between drying chamber 2 and cooling chamber 1. The slide gate valve 10 is controlled by an external controller and features vacuum isolation and a horizontal conveying channel. Drying chamber 2 and cooling chamber 1 each have their own vacuum systems consisting of extraction valves, extraction pipes, venting valves, and vacuum pumps, capable of achieving the vacuum environment required for the process. Installing two electric slide gate valves 10 can form an integrated vacuum chamber, providing a channel for sample transfer, while also allowing the three chambers to independently maintain the required atmospheric or vacuum environment.

[0037] A sealing base cover 5 is installed on the cooling platform 4 inside the cooling chamber 1. The sealing base cover 5 is located between the two left and right transfer tracks 18, and the height of the upper surface of the sealing base cover 5 is not higher than the height of the upper surface of the transfer track 18. This ensures that the glass container 21 containing the sample is transported to the sealing base cover 5. A sealing seat 13 is installed at the top of the cooling chamber 1. The sealing seat 13 is an integral structure of the top of the drying chamber 2. A lifting device 6 is installed on the sealing seat 13. The lifting device 6 includes a drive device 22, a telescopic rod 14, and a pressure plate 15. The drive device 22 is located outside the cooling chamber 1. The telescopic rod 14 slides on the sealing seat 13, which not only enables the telescopic rod 14 to move up and down but also ensures the vacuum environment inside the cooling chamber 1. A pressure plate 15 is installed at the bottom of the telescopic rod 14. The pressure plate 15 and the bottom of the telescopic rod 14 are connected by an elastic element 23. A sealing container 7 can also be detachably connected to the bottom of the pressure plate 15. The sealing container 7 can be fixed to the pressure plate 15 by a snap-fit ​​method. The sealing tank 7 is located directly on the cooling platform 4.

[0038] After the glass container 21 containing the sample enters the cooling platform 4, the lifting device 6 starts working, and the drive device 22 drives the telescopic rod 14 to move downward, bringing the sealing container 7 at the bottom of the pressure plate 15 into contact with the sealing bottom cover 5 on the cooling platform 4. The pressure plate 15 and the telescopic rod 14 are elastically connected, providing a buffering effect when the sealing container 7 contacts the sealing bottom cover 5, preventing damage to both and compromising the seal. Once the sealing container 7 is tightly sealed with the sealing bottom cover 5 on the cooling platform 4, the vent valve of the cooling chamber 1 is opened. Under atmospheric pressure, the sealing container 7 and the sealing bottom cover 5 are firmly sealed, creating a vacuum environment inside, thus completing the vacuum sealing process. Samples treated with the drying and cooling process can be stored in the container in a vacuum environment for a long time to avoid contamination and are also easy to carry.

[0039] It should be noted that the bottom of the encapsulation container 7 is provided with an annular wing plate structure forming a sealing end. A sealing assembly 16, including a sealing ring, is provided between the sealing end of the encapsulation container 7 and the bottom cover 5. Specifically, the sealing ring 16 can be provided on the bottom cover 5 or on the sealing end of the bottom of the encapsulation container 7. Since the surface area of ​​the bottom cover 5 is larger than the surface area of ​​the sealing end of the encapsulation container 7, it is preferable to provide the sealing ring on the sealing end to ensure an effective sealing fit between the encapsulation container 7 and the bottom cover 5. Of course, the sample on the cooling platform 4 can be cooled before encapsulation or encapsulated before cooling.

[0040] The cooling platform 4 is also equipped with a cooling system, which includes several cooling water pipes 12 arranged inside the cooling platform 4 and connected together. By circulating cooling water through the cooling water pipes 12, the sample can be effectively cooled through cooling water circulation. In addition, an infrared thermometer 17 is also installed on the cooling platform 4 to monitor the temperature of the cooling platform 4 in real time.

[0041] It should also be noted that the transfer assembly 3 consists of components such as a housing, lead screw, lead screw nut, guide rail, and slider, and is controlled and driven by a vacuum servo motor. The vacuum servo motor is connected to the lead screw through a coupling, driving the lead screw to rotate in the forward or reverse direction. Support seats are installed at both ends of the lead screw, and a lead screw nut is installed on the lead screw, converting the rotational motion of the lead screw into the linear motion of the nut. The guide rail and slider inside the transfer assembly play a guiding and stabilizing role. The lead screw nut and slider are fixedly installed together to form a linear motion assembly. An inductive switch is installed in the housing to control the movement position of the slider to achieve closed-loop control. A push rod 24 is installed on the slider, which controls the vacuum servo motor to achieve linear transfer of the sample.

[0042] The working principle of this scheme is as follows: When the drying chamber 2 is working, the gate valve 10 between the drying chamber 2 and the cooling chamber 1 needs to be closed, and the vacuum pump needs to be started to evacuate the drying chamber 2; when the cooling chamber 1 is working, the gate valves 10 on both sides also need to be closed, and the vacuum pump needs to be started to evacuate the cooling chamber 1; when it is necessary to transfer the sample from the drying chamber 2 to the cooling chamber 1, the gate valve 10 is opened, and the vacuum degree of the drying chamber 2 is balanced in the two chambers through the vacuum isolation and transfer channel of the gate valve 10; after the sealing is completed, the vent valve of the cooling chamber 1 is opened, and finally the container of the sealed sample is taken out from the side door of the cooling chamber 1.
