Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to a rare earth oxide ceramic humidity control oven. Background Technology

[0002] Rare earth oxide ceramics are extremely sensitive to humidity during the preparation process. Inaccurate humidity control during drying can easily lead to moisture absorption, cracking, or performance degradation in the ceramic materials. Traditional drying ovens typically focus on temperature control, lacking effective humidity monitoring and regulation mechanisms. Existing technologies often employ a single humidity sensor or a simple ventilation design, failing to achieve multi-point, real-time humidity monitoring and closed-loop control. This results in uneven humidity distribution within the drying chamber, affecting the uniformity and quality stability of the ceramic materials. Furthermore, traditional drying ovens easily introduce external humid air during material handling, disrupting the drying environment and increasing energy consumption. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problem that the existing drying ovens often use a single humidity sensor or a simple ventilation design, which cannot realize multi-point, real-time humidity monitoring and closed-loop control, resulting in uneven humidity distribution in the drying chamber and affecting the uniformity and quality stability of ceramic materials, a rare earth oxide ceramic humidity control drying oven is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a rare earth oxide ceramic humidity control drying oven, including a dryer, a blower, a heater, a drying chamber, and an exhaust fan. The output end of the dryer is connected to the input end of the blower, and the dryer is used to remove moisture from the air. The output end of the blower is connected to the input end of the heater, and the output end of the heater is connected to the air inlet of the drying chamber, and the heater is used to heat the air. The air outlet of the drying chamber is connected to the input end of the exhaust fan. The drying oven is equipped with a first humidity sensor, a second humidity sensor, and a third humidity sensor. The first humidity sensor detects the humidity of the air entering through the air inlet, the second humidity sensor detects the humidity of the air in the drying chamber, and the third humidity sensor detects the humidity of the air exiting through the air outlet. By setting up the first, second, and third humidity sensors, the humidity of the air inlet, the drying chamber, and the air outlet are monitored respectively, realizing real-time humidity monitoring at multiple points throughout the process. Combined with the automatic adjustment of the control box, it ensures that the humidity in the drying chamber remains stable within the set range, thereby improving the drying quality and consistency of rare earth oxide ceramics.

[0005] To address the problem of independent operation of equipment components, making unified control and automated adjustment difficult, and resulting in complex and inefficient operation, the humidity control oven further includes a control box. The control box is used to control the equipment components and is electrically connected to the dryer, the supply fan, the heater, the exhaust fan, the first humidity sensor, the second humidity sensor, and the third humidity sensor.

[0006] To address the issue of users being unable to intuitively obtain humidity information and make real-time adjustments, which limits the flexibility of the device and the user experience, the system further includes a humidity display and control buttons on the control box.

[0007] To address the issue of uneven airflow within the drying oven, which leads to inconsistent heating and humidity distribution of materials and affects drying uniformity, the following further design includes several partitions arranged inside the drying oven. These partitions divide the space within the drying oven into an air inlet chamber, a drying chamber, a confluence chamber, and an air outlet chamber. The air inlet chamber is connected to the air inlet. Several first through holes, second through holes, and third through holes are provided on the partitions. The first through hole connects the air inlet chamber and the drying chamber, the second through hole connects the drying chamber and the confluence chamber, the third through hole connects the confluence chamber and the air outlet chamber, and the air outlet chamber is connected to the air outlet. The drying chamber is equipped with boxes for placing materials.

[0008] To address the issues of difficulty in handling materials and the potential disruption of the drying chamber's sealed environment by introducing humid air, a sliding connection between the box body and partitions is further incorporated.

[0009] To address the issue of humid air intrusion or energy loss caused by the connection between the drying chamber and the external chamber during material handling, the system further includes a first through-hole and a second through-hole located on the front side of the drying chamber. The box body is provided with a fourth through hole for communicating with the first through hole and a fifth through hole for communicating with the second through hole; When the box is located in the drying chamber, the first through hole and the fourth through hole are connected, and the second through hole and the fifth through hole are connected; When the box is pulled out, it can close the first and second through holes, thus disconnecting the drying chamber from the air inlet chamber and the drying chamber from the manifold.

[0010] The beneficial effects of this utility model are as follows: The rare earth oxide ceramic humidity control oven provided by this utility model monitors the humidity of the air inlet, drying chamber and air outlet by setting a first humidity sensor, a second humidity sensor and a third humidity sensor, respectively, realizing real-time humidity monitoring of the whole process and multiple points. Combined with the automatic adjustment of the control box, it ensures that the humidity in the drying chamber is stable within the set range, thereby improving the drying quality and consistency of rare earth oxide ceramics.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1 This is a schematic diagram of the structure of this utility model, a rare earth oxide ceramic humidity control drying oven, including a dryer 1, a blower 2, a heater 3, a drying chamber 4, and an exhaust fan 5. The output end of the dryer 1 is connected to the input end of the blower 2, and the dryer 1 is used to remove moisture from the air. The output end of the blower 2 is connected to the input end of the heater 3, and the output end of the heater 3 is connected to the air inlet 46 of the drying chamber 4, and the heater 3 is used to heat the air. The air outlet 47 of the drying chamber 4 is connected to the input end of the exhaust fan 5. By using the dryer 1 to remove moisture from the air in advance, and combined with the heating by the heater 3, the air entering the drying chamber 4 is made dry and at a suitable temperature, reducing energy waste. The exhaust fan 5 promptly discharges humid air, maintaining a low humidity environment in the drying chamber 43 and improving drying efficiency. like Figure 1As shown, the drying oven 4 is equipped with a first humidity sensor 6, a second humidity sensor 7, and a third humidity sensor 8. The first humidity sensor 6 is used to detect the humidity of the air entering through the air inlet 46, the second humidity sensor 7 is used to detect the humidity of the air in the drying chamber 43 inside the drying oven 4, and the third humidity sensor 8 is used to detect the humidity of the air output through the air outlet 47. By setting the first humidity sensor 6, the second humidity sensor 7, and the third humidity sensor 8 to monitor the humidity of the air inlet, the drying chamber 43, and the air outlet respectively, real-time humidity monitoring at multiple points throughout the process is achieved. Combined with the automatic adjustment of the control box, the humidity in the drying chamber 43 is kept stable within the set range, thus improving the drying quality and consistency of rare earth oxide ceramics.

[0016] like Figure 1 As shown, the humidity control oven also includes a control box 9, which is used to control the equipment components. The control box 9 is electrically connected to the dryer 1, the air supply fan 2, the heater 3, the exhaust fan 5, the first humidity sensor 6, the second humidity sensor 7, and the third humidity sensor 8, realizing centralized control and automated management, improving the system response speed and ease of operation, and reducing the need for human intervention.

[0017] The control box 9 has a humidity display 91 and control buttons 92. The control box 9 is equipped with a humidity display 91 and control buttons 92, which allows users to view humidity data in real time and manually adjust parameters, simplifying the operation process and enhancing the controllability and convenience of the equipment.

[0018] like Figure 2 , 3 As shown, the drying chamber 4 is equipped with several partitions 41, which divide the space inside the drying chamber 4 into an air inlet chamber 42, a drying chamber 43, a confluence chamber 44, and an air outlet chamber 45. The air inlet chamber 42 is connected to the air inlet 46. Several first through holes 411, second through holes 412, and third through holes 413 are provided on the partitions 41. The first through holes 411 connect the air inlet chamber and the drying chamber 43, the second through holes 412 connect the drying chamber 43 and the confluence chamber 44, and the third through holes 413 connect the confluence chamber 44 and the air outlet chamber 45. The air outlet chamber 45 is connected to the air outlet 47. The drying chamber 4 is divided into an air inlet chamber 42, a drying chamber 43, a confluence chamber 44, and an air outlet chamber 45 by the partitions 41 and is equipped with multiple through holes to make the air flow more uniform, avoid local over-wetness or over-dryness, and ensure that the material is heated evenly. The drying chamber 43 is equipped with boxes 48 for placing materials.

[0019] like Figure 2 , 3As shown, the box body 48 and the partition 41 are slidably connected. The box body 48 and the partition 41 are slidably connected through the structure of the slide rail and the slide groove. The slidable connection between the box body 48 and the partition 41 simplifies the material handling process and maintains the relative sealing of the drying chamber 43 during movement, reducing environmental interference.

[0020] Both the first through hole 411 and the second through hole 412 are located on the front side of the drying chamber 43; like Figure 2 , 3 As shown, the box body 48 is provided with a fourth through hole 481 for communicating with the first through hole 411 and a fifth through hole 482 for communicating with the second through hole 412. The box body 48 is provided with the fourth through hole 481 and the fifth through hole 482, and automatically closes the first through hole 411 and the second through hole 412 when it is pulled out, effectively isolating the drying chamber 43, preventing the entry of humid air and heat loss, and improving energy utilization and drying stability. When the box 48 is located in the drying chamber 43, the first through hole 411 and the fourth through hole 481 are connected, and the second through hole 412 and the fifth through hole 482 are connected. When the box 48 is pulled out, the box 48 can close the first through hole 411 and the second through hole 412, thereby disconnecting the drying chamber 43 from the air inlet chamber 42 and the drying chamber 43 from the manifold 44.

[0021] Working process: Dryer 1 starts up to remove moisture from the air and generate dry air; blower 2 delivers the dry air to heater 3; heater 3 heats the dry air, and the heated air enters the air inlet chamber 42 of drying chamber 4 through air inlet 46; the air enters the drying chamber 43 from the air inlet chamber 42 through the first through hole 411, comes into contact with the rare earth oxide ceramic material placed in box 48, and removes the moisture from the surface of the material; second humidity sensor 7 monitors the humidity of drying chamber 43 in real time; the air carrying moisture enters the confluence chamber 44 through the second through hole 412, then enters the air outlet chamber 45 through the third through hole 413, and finally exits through the air outlet 47. The exhaust fan 5 discharges the air from the system; the first humidity sensor 6 detects the humidity of the incoming air, and the third humidity sensor 8 detects the humidity of the outgoing air; the control box 9 receives data from all humidity sensors and automatically adjusts the operating parameters of the dryer 1, heater 3, air supply fan 2, and exhaust fan 5 by comparing the set value with the actual value to maintain the target humidity in the drying chamber 43; when materials need to be removed or placed, the box 48 is pulled out, and the box 48 automatically closes the first through hole 411 and the second through hole 412, cutting off the connection between the drying chamber 43 and the air inlet chamber 42 and the confluence chamber 44 to prevent external air from entering; after the box 48 is put back, the through holes are reconnected, and normal operation is restored.
