Description

Technical Field

[0001] This utility model relates to the technical field of steam drying equipment, specifically a steam drying oven with a built-in uniform air intake structure. Background Technology

[0002] Aerogel felt is a flexible thermal insulation material made of nano-silica or metal aerogel as the main body and reinforced with composite glass fiber, pre-oxidized fiber and other materials. In the production process of aerogel felt, a steam oven is required for drying. The steam oven, also known as a steam heating oven, can use heat sources such as steam (0.2-0.8MPa), electricity, far-infrared and so on. The steam heating temperature range is 50-150℃, and the electric heating can reach 350℃.

[0003] However, existing steam ovens generally deliver steam directly into the oven through steam pipes or fans. The temperature is higher near the steam pipes or fans and lower further away. This uneven heating of the product during the drying process inside the steam oven results in poor drying performance.

[0004] For example, the aforementioned problem exists in patent (CN220771769U); it describes "a carbon felt steam drying device, belonging to the technical field of carbon felt production equipment, the drying device including a steam oven, a gas storage tank, an outlet drive device and a steam pipe; the outlet drive device is located at the outlet end of the drying device, used to pull the carbon felt to move closely against the upper surface of the steam oven; the gas outlet of the gas storage tank is connected to the steam oven through the steam pipe, used to provide high-temperature steam to the steam oven to dry the carbon felt. This utility model utilizes high-temperature steam to dry carbon felt, which is energy-saving and environmentally friendly, and has high production efficiency and is easy to maintain." In the above patent, high-temperature steam is directly transported into the steam oven through the steam pipe. The temperature of the steam inside the steam oven is higher near the steam pipe and lower further away from the steam pipe. The product is not heated evenly during the drying process inside the steam oven, resulting in poor drying effect.

[0005] To address the problem mentioned above, where products are typically transported directly into the steam oven via steam pipes or fans, resulting in uneven heating during the drying process and poor drying performance, we propose a steam oven with a built-in uniform air intake structure. Summary of the Invention

[0006] The purpose of this invention is to provide a steam oven with a built-in uniform air intake structure to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a steam oven with a built-in uniform air intake structure, including a steam oven, an air guide box at the top of the steam oven, a plurality of steam delivery ports at the top of the air guide box, a first air guide mechanism horizontally arranged at the top of the inner wall of the air guide box, a plurality of second air guide mechanisms horizontally arranged at the bottom of the inner wall of the air guide box, an isolation plate between the steam oven and the air guide box, an opening at the top of the isolation plate that matches the second air guide mechanisms, and the second air guide mechanisms being rotatably disposed inside the opening.

[0008] Furthermore, the first air guiding mechanism includes a plurality of first support rods, both ends of which are rotatably connected to the air guiding box. A support cylinder is sleeved on the outer wall of the first support rod, and a first spiral blade and a second spiral blade are provided on the outer wall of the support cylinder. The first air guiding mechanism also includes a rotation drive assembly for the first support rod.

[0009] Furthermore, the rotary drive assembly includes a servo motor, a first chain, and a first double-row sprocket. The output end of the servo motor is provided with a sprocket that meshes with the first chain. One end of the outer wall of the first support rod is provided with a second double-row sprocket. The first double-row sprocket and the second double-row sprocket are staggered. The first chain meshes with an adjacent set of first double-row sprockets and second double-row sprockets. The adjacent first double-row sprockets and second double-row sprockets are connected by meshing with the second chain.

[0010] Furthermore, the servo motor, the first chain, the sprocket, the first double-row sprocket, the second double-row sprocket, and the second chain are all located on the outside of the air guide box, and the sprocket and the first double-row sprocket are rotatably connected to the outer wall of the air guide box.

[0011] Furthermore, the pitch of the first helical blade is greater than the pitch of the second helical blade, and the first support rod and the support cylinder are eccentrically arranged.

[0012] Furthermore, the first and second helical blades on the outer wall of the same first support rod have the same helical direction, while the first and second helical blades on the outer walls of two adjacent first support rods have opposite helical directions.

[0013] Furthermore, the second air guiding mechanism includes a second support rod, the two ends of which are rotatably connected to the two ends of the inner wall of the opening, and the outer wall of the second support rod is provided with a plurality of arc-shaped air guiding plates.

[0014] Furthermore, the arc-shaped air guide plates are evenly distributed in a vortex shape on the outer wall of the second support rod; the distribution angles of the arc-shaped air guide plates of two adjacent second air guide mechanisms are opposite.

[0015] Furthermore, the steam oven has symmetrical feeding ports at both ends of its outer wall, and a guide roller assembly is provided inside the steam oven between the two feeding ports.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are: 1. This utility model, by setting up a steam oven, an air guide box, a steam inlet, a first air guide mechanism, a second air guide mechanism, an isolation plate, and an opening, provides a steam oven. The air guide box at the top of the steam oven disperses the high-temperature steam before it enters the oven, ensuring that the high-temperature steam is evenly distributed inside. The first air guide mechanism disperses the high-temperature steam at the top inside the air guide box, and the second air guide mechanism disperses the high-temperature steam at the bottom of the air guide box. After these two dispersion treatments, the high-temperature steam is delivered into the steam oven, ensuring that it enters the oven evenly. This effectively improves the uniformity of the high-temperature steam distribution inside the oven, resulting in more even heating and drying of the product, leading to better drying results.

[0017] 2. In this utility model, the rotary drive assembly can drive the first support rod to rotate, and the first support rod can drive the support cylinder to rotate. The first spiral blade and the second spiral blade can rotate with the support cylinder. During the rotation, the first spiral blade and the second spiral blade perform a rotary spiral dispersion treatment on the high-temperature steam, so that the high-temperature steam sent from the steam conveyor can be rotary spirally dispersed inside the air guide box, making the high-temperature steam evenly distributed inside the air guide box, which can effectively improve the dispersion uniformity of the high-temperature steam entering the steam oven. During the process of the high-temperature steam moving downward inside the opening, the arc-shaped air guide plate rotates under the push of the high-temperature steam. When the high-temperature steam passes through the opening and enters the steam oven, it is rotary arc-shaped dispersed along the arc-shaped air guide plate, so that the high-temperature steam sent from the opening can be rotary arc-shaped dispersed at the top of the steam oven, making the high-temperature steam evenly distributed inside the steam oven, making the drying and heating of the product inside the steam oven more uniform, and the drying effect of the product better.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figures 1-2 and Figures 5-6 This utility model provides a technical solution: a steam oven with a built-in uniform air intake structure, including a steam oven 1, a top air guide box 2, a plurality of steam delivery ports 201 on the top of the air guide box 2, a first air guide mechanism 3 horizontally arranged on the top of the inner wall of the air guide box 2, a plurality of second air guide mechanisms 4 horizontally arranged on the bottom of the inner wall of the air guide box 2, an isolation plate 5 between the steam oven 1 and the air guide box 2, an opening 501 matching the second air guide mechanism 4 on the top of the isolation plate 5, the second air guide mechanism 4 being rotatably disposed inside the opening 501; the first air guide mechanism 3 includes a plurality of first support rods 301, both ends of the first support rods 301 being rotatably connected to the air guide box 2, a support cylinder 302 sleeved on the outer wall of the first support rods 301, a first spiral blade 303 and a second spiral blade 304 arranged on the outer wall of the support cylinder 302, and the first air guide mechanism 3 further includes a rotation drive assembly 305 for the first support rods 301; In one embodiment, the pitch of the first helical blade 303 is greater than the pitch of the second helical blade 304, so that the first helical blade 303 and the second helical blade 304 perform helical conveying operations with different widths on the outer wall of the support cylinder 302, which can effectively improve the diversity of high-temperature steam conveying directions and thus improve the uniformity of high-temperature steam intake; the first support rod 301 and the support cylinder 302 are eccentrically arranged, so that the rotational movement range of the support cylinder 302 around the outer wall of the first support rod 301 is larger, and the movement range of the first helical blade 303 and the second helical blade 304 on the outer wall of the support cylinder 302 is larger, which can effectively improve the diversity of high-temperature steam conveying directions and thus improve the uniformity of high-temperature steam intake.

[0021] In one embodiment, the first spiral blade 303 and the second spiral blade 304 on the outer wall of the same first support rod 301 have the same spiral direction, and the spiral directions of the first spiral blade 303 and the second spiral blade 304 on the outer walls of two adjacent first support rods 301 are opposite. This allows the first spiral blade 303 and the second spiral blade 304 on the outer walls of two adjacent first support rods 301 to perform spiral dispersion processing on high-temperature steam in different directions during the rotational motion, which can effectively improve the diversity of high-temperature steam conveying directions and thus improve the uniformity of high-temperature steam intake.

[0022] In one embodiment, the steam oven 1 has symmetrically arranged feeding ports 101 at both ends of its outer wall. The two feeding ports 101 provide feeding channels at both ends of the outer wall of the steam oven 1, so that the product to be dried is fed into the steam oven 1 from one feeding port 101 and then removed from the other feeding port 101. Inside the steam oven 1, between the two feeding ports 101, a guide roller assembly 102 is provided. The guide roller assembly 102 provides rolling guidance and support for the product to be dried inside the steam oven 1, which can effectively ensure that the product to be dried can normally enter and exit the steam oven 1.

[0023] The working principle of this utility model: Refer to the instruction manual appendix Figures 1-2 and Figures 5-6This utility model comprises a steam oven 1, an air guide box 2, a steam inlet 201, a first air guide mechanism 3, a second air guide mechanism 4, an isolation plate 5, and an opening 501. The steam oven 1 provides a drying space for the products to be dried. The air guide box 2 disperses the high-temperature steam at the top of the steam oven 1, pre-dispersing the high-temperature steam before it enters the steam oven 1, ensuring that the high-temperature steam is evenly dispersed. The high-temperature steam is fed into the air guide box 2 through the steam inlet 201. The first air guide mechanism 3 disperses the high-temperature steam entering the air guide box 2 at the top inner side of the air guide box 2. The second air guide mechanism 4 disperses the high-temperature steam entering the air guide box 2. The bottom undergoes secondary air-guiding and dispersion treatment of high-temperature steam. The isolation plate 5 provides isolation and support between the steam oven 1 and the air guide box 2, which can effectively prevent high-temperature steam from directly entering the steam oven 1. The opening 501 provides installation space for the second air guide mechanism 4. As the high-temperature steam passes through the opening 501, it is guided into the steam oven 1 by the second air guide mechanism 4. After being dispersed by air twice, the high-temperature steam is sent into the steam oven 1, which makes the high-temperature steam evenly enter the steam oven 1. This can effectively improve the uniformity of the distribution of high-temperature steam entering the steam oven 1, making the product more evenly heated during drying in the steam oven 1, and resulting in better product drying effect. In the first air guiding mechanism 3, the first support rod 301 supports the support cylinder 302, and the support cylinder 302 supports the first spiral blade 303 and the second spiral blade 304. The rotary drive assembly 305 can drive the first support rod 301 to rotate, causing the first support rod 301 to rotate. The first support rod 301 can drive the support cylinder 302 to rotate, and the first spiral blade 303 and the second spiral blade 304 can rotate with the support cylinder 302. During the rotation, the first spiral blade 303 and the second spiral blade 304 can perform rotary spiral dispersion of high-temperature steam, so that the high-temperature steam sent from the steam conveying port 201 can be rotary spiral dispersed inside the air guiding box 2, so that the high-temperature steam is evenly distributed inside the air guiding box 2. This can effectively improve the dispersion uniformity of the high-temperature steam entering the steam oven 1, making the product more evenly heated during drying inside the steam oven 1, and resulting in a better drying effect. Example 2

[0024] Please see Figures 1-6This utility model provides a technical solution: a steam oven with a built-in uniform air intake structure. The rotary drive assembly 305 includes a servo motor 306, a first chain 307, and a first double-row sprocket 309. The output end of the servo motor 306 is provided with a sprocket 308 that meshes with the first chain 307. One end of the outer wall of the first support rod 301 is provided with a second double-row sprocket 310. The first double-row sprockets 309 and the second double-row sprockets 310 are staggered. The first chain 307 meshes with an adjacent set of first double-row sprockets 309 and second double-row sprockets 310. Adjacent first double-row sprockets 309 and second double-row sprockets 310 are connected by a second chain 311. The second air guide mechanism 4 includes a second support rod 401. The two ends of the second support rod 401 are rotatably connected to the two ends of the inner wall of the opening 501. The outer wall of the second support rod 401 is provided with a plurality of arc-shaped air guide plates 402.

[0025] In one embodiment, the servo motor 306, the first chain 307, the sprocket 308, the first double-row sprocket 309, the second double-row sprocket 310, and the second chain 311 are all located outside the air guide box 2. This effectively ensures the normal operation of the servo motor 306, the first chain 307, the sprocket 308, the first double-row sprocket 309, the second double-row sprocket 310, and the second chain 311, preventing high-temperature steam from affecting the rotary drive assembly 305 and preventing materials such as lubricating oil on the rotary drive assembly 305 from contaminating the high-temperature steam entering the steam oven 1. The sprocket 308 and the first double-row sprocket 309 are rotatably connected to the outer wall of the air guide box 2, effectively ensuring the stability of the rotational movement of the sprocket 308 and the first double-row sprocket 309.

[0026] In one embodiment, the arc-shaped air guide plate 402 is evenly distributed in a vortex shape on the outer wall of the second support rod 401. By setting the distribution shape of the arc-shaped air guide plate 402, the high-temperature steam pushes the arc-shaped air guide plate 402 in a vortex structure, and the high-temperature steam is vortexed and dispersed in a vortex shape at the top of the inner side of the steam oven 1 below the opening 501, so that the high-temperature steam is evenly distributed inside the steam oven 1. The distribution angles of the arc-shaped air guide plates 402 of the two adjacent second air guide mechanisms 4 are opposite. By setting the distribution angles of the arc-shaped air guide plates 402 of the second air guide mechanism 4, the arc-shaped air guide plates 402 of the two adjacent second air guide mechanisms 4 can perform rotational dispersion treatment of the high-temperature steam at different angles, which can further improve the uniformity of the distribution of high-temperature steam inside the steam oven 1.

[0027] The working principle of this utility model: Refer to the instruction manual appendix Figures 1-6This invention, through the configuration of a rotary drive assembly 305 including a servo motor 306, a first chain 307, and a first double-row sprocket 309, allows the output of the servo motor 306 to drive the sprocket 308 to rotate. The sprocket 308 is connected to an adjacent set of first double-row sprockets 309 and second double-row sprockets 310 via the first chain 307. The rotational movement of the sprocket 308 can drive the first double-row sprockets 309 and second double-row sprockets 310 to rotate via the first chain 307, and the rotational movements of the first double-row sprockets 309 and second double-row sprockets 310 are in the same direction. The first double-row sprockets 309 and second double-row sprockets 310 are further connected via a second chain 319. 1. Drive the adjacent first double-row sprocket 309 or second double-row sprocket 310 to mesh and transmit power, so that all the first double-row sprockets 309 and second double-row sprockets 310 rotate in the same direction. The second double-row sprocket 310 drives the first support rod 301 to rotate. The first support rod 301 drives the first spiral blade 303 and second spiral blade 304 to rotate through the support cylinder 302, so as to realize the rotational spiral dispersion treatment of high-temperature steam, so that the high-temperature steam sent from the steam conveying port 201 can be rotated spirally dispersed inside the air guide box 2, so that the high-temperature steam is evenly distributed inside the air guide box 2. The second air guiding mechanism 4 includes a second support rod 401 and an arc-shaped air guiding plate 402. The second support rod 401 supports the arc-shaped air guiding plate 402 and can rotate inside the opening 501. The arc-shaped air guiding plate 402 rotates along with the second support rod 401. After the high-temperature steam is guided and dispersed by the first air guiding mechanism 3, it evenly impacts the surface of the isolation plate 5. The high-temperature steam moves downward through the opening 501 at the top of the isolation plate 5. During its downward movement inside the opening 501, the high-temperature steam impacts the surface of the arc-shaped air guiding plate 402 on the outer wall of the second support rod 401. Steam drives the arc-shaped air guide plate 402, and the second support rod 401 provides rotational support for the arc-shaped air guide plate 402, ensuring that the arc-shaped air guide plate 402 rotates under the drive of high-temperature steam. Driven by the rotation of the arc-shaped air guide plate 402, the high-temperature steam passes through the opening 501 and enters the steam oven 1. When the high-temperature steam passes through the opening 501 and enters the steam oven 1, it is rotated and dispersed in an arc shape along the arc-shaped air guide plate 402, so that the high-temperature steam sent in from the opening 501 can be rotated and dispersed in an arc shape at the top of the steam oven 1, so that the high-temperature steam is evenly distributed inside the steam oven 1, making the drying and heating of the product inside the steam oven 1 more uniform and the drying effect of the product better. The servo motor 306 model can be selected according to actual needs; A protective cover (not shown in the figure) can be arranged on the outer wall of the air guide box 2 outside the rotary drive assembly 305, and corresponding lubrication treatment can be performed at the same time.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
