Description

Technical Field

[0001] The utility model relates to the technical field related to environmental testing equipment, and in particular to an aramid paper honeycomb oven. Background Art

[0002] Aramid fiber paper honeycomb is made of aramid fiber paper through impregnation, curing and shaping processes. The essence of the curing and shaping process is the chemical cross-linking reaction between resin and curing agent. This process directly determines the important properties of honeycomb products such as mechanical properties, electromagnetic properties, and physical properties, and is a key process in the manufacturing process. The curing process requires that the honeycomb cells are heated uniformly and dried quickly. The commonly used equipment for the curing process is a blast drying oven, which heats the aramid paper honeycomb block with electric hot air, quickly evaporates and discharges the liquid material, maintains a stable and uniform temperature and air volume, and provides a suitable cross-linking reaction environment for the honeycomb block, so that the inside of the oven and the honeycomb are heated evenly. However, this blast drying oven lacks an exhaust and dehumidification control mechanism, such as exhaust and dehumidification during heating and exhaust during cooling. When the exhaust pressure is high or the exhaust air path is not smooth, the volatiles will fill the oven, and there is a risk of condensation and adhesion to the side wall of the oven and the surface of the honeycomb when it is cold, which will lead to uneven material on the surface of the honeycomb.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0026] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0027] A kind of aramid paper honeycomb oven, see Figures 1 to 3 The aramid paper honeycomb oven includes an outer shell 1, an inner shell 2 and a dehumidification mechanism 3. The outer shell 1 has a storage space inside, the inner shell 2 is arranged in the storage space, and the inner cavity of the inner shell 2 is connected to the storage space. The exhaust mechanism includes an exhaust pipe 31, a temperature exhaust drive component, a sensor component 33 and a controller. The exhaust pipe 31 is arranged on the outer shell 1 and is connected to the storage space. The dehumidification drive component 32 is arranged on the exhaust pipe 31 and provides power for the circulation of gas inside the exhaust pipe 31. The sensor component 33 is arranged on the exhaust pipe 31 for detecting the temperature and pressure in the exhaust pipe 31. The controller is electrically connected to the sensor component 33 and the dehumidification drive component 32.

[0028] Specifically, the outer shell 1 serves as the external structure of the entire oven, and plays the role of supporting, containing and protecting. The inner shell 2 is arranged inside the outer shell 1. The interior of the inner shell 2 is used to place materials. The inner shell 2 can protect the materials placed in the inner shell 2. The gap between the inner shell 2 and the outer shell 1 is for air circulation.

[0029] In this embodiment, if Figure 1 As shown, the length direction of the outer shell 1 and the inner shell 2 is the X direction shown in the figure, the width direction of the outer shell 1 and the inner shell 2 is the Y direction shown in the figure, and the height direction of the outer shell 1 and the inner shell 2 is the Z direction shown in the figure.

[0030] Furthermore, the sensor component 33 will detect the humidity value in the oven, and after comparing it with the preset standard value in the controller, when the internal humidity of the oven is high, the controller will drive the dehumidification drive component 32 to work, accelerate the air circulation in the oven, and make the air in the oven be discharged through the exhaust pipe 31. The discharged air will contain a certain amount of water vapor, thereby reducing the humidity value of the air in the oven. The requirements of the dehumidification and exhaust process of the aramid paper honeycomb curing and shaping are met, energy saving and emission reduction are achieved, the problem of uneven appearance is improved, and the batch consistency and stability of the aramid paper honeycomb are improved.

[0031] It should be noted that the outer shell 1 is not only in circulation with the outside air through the exhaust pipe 31, but in the actual structure, for example, there will be a relatively small gap at the connection position between the outer shell 1 and different sides for the outer shell 1 to circulate with the outside air. However, due to the small gap, the air circulation efficiency at these gap positions is low. When the dehumidification drive component 32 is working, the interior of the outer shell 1 will be in a negative pressure state. At this time, the outside air will be injected into the outer shell 1 through the gap to balance the air pressure inside and outside the outer shell 1.

[0032] Furthermore, an air duct 21 communicating with the inner shell 2 is formed between the inner shell 2 and the outer shell 1 , and the exhaust pipe 31 is communicating with the air duct 21 .

[0033] Since the volume of the inner shell 2 is smaller than that of the outer shell 1 , there is a gap between the inner shell 2 and the outer shell 1 . This gap is the air duct 21 for gas to flow inside the outer shell 1 . The air duct 21 circulates with the interior of the inner shell 2 . The air duct 21 is connected to the exhaust pipe 31 , and the gas inside the inner shell 2 can be discharged through the air duct 21 .

[0034] In this embodiment, along the length direction of the outer shell 1 , the distance between the moisture removal mechanism 3 and the first end of the outer shell 1 is greater than the distance between the moisture removal mechanism 3 and the second end of the outer shell 1 .

[0035] By setting the dehumidification mechanism 3 on one side of the center position in the length direction of the outer shell 1, it is convenient to better enable the gas flow in the air duct 21 and the inner shell 2 when the dehumidification drive component 32 is working, so as to facilitate the discharge of the gas in the accommodating space and improve the exhaust effect.

[0036] Furthermore, the dehumidification drive component 32 includes a pressure-stabilizing drive fan 321 and a ventilation fan 322. The pressure-stabilizing drive fan 321 is arranged on one side of the exhaust pipe 31 close to the outlet end; the ventilation fan 322 is arranged on one side of the exhaust pipe 31 close to the inlet end.

[0037] Specifically, the ventilation fan 322 serves as the main power source, providing negative pressure to discharge the air in the accommodation space through the exhaust pipe 31. The voltage-stabilizing driving fan 321 plays an auxiliary role, mainly used to balance the air pressure in the accommodation space and the outside world, to avoid the external gas from backflowing into the oven or the internal gas from being unable to be discharged, and to ensure the exhaust and dehumidification process.

[0038] Furthermore, the sensor assembly 33 includes a first sensor 331, a second sensor 332 and a third sensor 333. The first sensor 331 is arranged between the pressure-stabilizing driving fan 321 and the ventilation fan 322; the second sensor 332 is arranged between the pressure-stabilizing driving fan 321 and the outlet end of the exhaust pipe 31; and the third sensor 333 is arranged between the ventilation fan 322 and the inlet end.

[0039] Among them, sensors at different positions play different roles. The first sensor 331 is located between the voltage-stabilizing driving fan 321 and the ventilation fan 322, and is mainly used to detect the air pressure between the voltage-stabilizing driving fan 321 and the ventilation fan 322. The second sensor 332 is located between the voltage-stabilizing driving fan 321 and the outlet end of the exhaust pipe 31, and is mainly used to detect the air pressure at this position. When the air pressure of the first sensor 331 and the second sensor 332 is different, the controller will send a signal to drive the voltage-stabilizing driving fan 321 to work and balance the air pressure inside and outside the oven. The third sensor 333 is located between the ventilation fan 322 and the inlet end of the exhaust pipe 31, and is mainly used to detect the humidity in the oven. When the detected humidity is greater than the preset value, the controller controls the ventilation fan 322 to work and dehumidify the oven.

[0040] Furthermore, the dehumidification mechanism 3 also includes a first one-way valve 34 and a second one-way valve 35. The first one-way valve 34 is arranged at the outlet end of the exhaust pipe 31; the second one-way valve 35 is arranged on the exhaust pipe 31 and is located between the pressure-stabilizing drive fan 321 and the first sensor 331.

[0041] The first one-way valve 34 and the second one-way valve 35 play a one-way conduction role, so that air can only flow from the oven to the outside. By setting the first one-way valve 34 and the second one-way valve 35, it is possible to prevent the external gas from flowing back into the oven and mixing, thereby increasing the stability of the exhaust and dehumidification process.

[0042] In this embodiment, the aramid paper honeycomb oven also includes a circulation fan 4 arranged on the outer shell 1, which provides a driving force for the gas flow inside the accommodating space. The circulation fan 4 includes a fan body arranged outside the outer shell 1 and a volute 41 arranged inside the accommodating space.

[0043] The circulating fan 4 assists in the air circulation, and can accelerate the circulation of the gas in the storage space through the circulating fan 4, which is beneficial to the exhaust process. The volute 41 plays a role in uniform airflow, which can make the air in the storage space communicate with the vent, which is beneficial to exhaust and dehumidify the oven.

[0044] Furthermore, along the length direction of the outer shell 1, the circulation fan 4 is arranged at the center position of the top of the outer shell 1. Since the volute 41 plays a role in uniform airflow, the circulation fan 4 is arranged at the center position of the top of the outer shell, so that the volute 41 can better uniform the airflow.

[0045] It should be noted that the arrangement of the circulating fan 4 is not limited to the above-mentioned central position, and the distance between the circulating fan 4 and the second end of the outer shell 1 can also be greater than the distance between the dehumidification mechanism 3 and the first end of the outer shell 1, and the circulating fan 4 is arranged on the side of the center of the top of the outer shell 1 away from the dehumidification mechanism 3. Among them, the circulating fan 4 is arranged at a non-central position on the top of the outer shell, so that the distance between the circulating fan 4 and the two sides of the outer shell 1 is different, so that the arrangement position of the circulating fan 4 can be designed according to the position of the dehumidification mechanism 3, which is conducive to the circulation of gas in the accommodation space and assists the exhaust and dehumidification of the oven.

[0046] In this embodiment, grilles 5 are provided on a group of oppositely disposed side walls of the inner shell 2 along the length direction of the outer shell 1 , and the outer shell 1 and the inner shell 2 are connected to each other through the grilles 5 .

[0047] By arranging the grille 5 on the inner shell 2, the air in the inner shell 2 and the air in the storage space can be communicated with each other. When the grille 5 is arranged on a set of oppositely arranged side walls of the inner shell 2, when the air is communicated, the air will enter from one side and be discharged from the other side, and then the air circulation can be circulated through the function formed in the storage space, thereby facilitating the exhaust and dehumidification of the oven.

[0048] In this embodiment, the aramid paper honeycomb oven further comprises a heating assembly 6 , which is disposed inside the air duct 21 between the inner shell 2 and the outer shell 1 .

[0049] By providing the heating assembly 6, the drying efficiency of the honeycomb can be improved.

[0050] In this embodiment, the aramid paper honeycomb oven further includes a trolley 7, which is used to place a feeding block 71. The feeding block 71 is placed on the trolley 7, and the feeding block 71 is loaded and unloaded by the trolley 7, which is more convenient, reduces the transportation engineering, and reduces the work intensity of workers.

[0051] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0052] 1. When the internal humidity of the oven is high, the controller will drive the dehumidification drive component 32 to work, accelerate the air circulation in the oven, and make the air in the oven be discharged through the exhaust pipe 31. The exhausted air will contain a certain amount of water vapor, thereby reducing the humidity value of the air in the oven, meeting the dehumidification and exhaust process requirements of the aramid paper honeycomb curing and shaping, saving energy and reducing emissions, improving the problem of uneven appearance, and improving the batch consistency and stability of the aramid paper honeycomb.

[0053] 2. The ventilation fan 322 serves as the main power source, providing negative pressure to discharge the air in the accommodation space through the exhaust pipe 31. The voltage-stabilizing driving fan 321 plays an auxiliary role, mainly used to balance the air pressure in the accommodation space and the outside world, to avoid the external air from backflowing into the oven or the internal air from being unable to be discharged, and to ensure the exhaust and dehumidification process.

[0054] 3. The circulating fan 4 plays a role in assisting air circulation. Through the circulating fan 4, the circulation of gas in the accommodation space can be accelerated, which is conducive to the exhaust process. Among them, the volute 41 plays a role in uniform airflow, which can make the air in the accommodation space connected to the vent, which is conducive to exhausting and dehumidifying the oven.
