Description

Technical Field

[0001] This utility model relates to the field of vacuum drying oven technology, and in particular to a double-layer vacuum drying oven. Background Technology

[0002] Chinese patent document CN215832342U discloses a double-layer vacuum drying oven, relating to the field of vacuum drying equipment technology. It includes a shell, an inner chamber, and a partition in the middle of the inner chamber. A shielding plate is located on the inner surface of the chamber and above the partition. A shielding door is rotatably connected to the upper surface of the partition and the position corresponding to the shielding plate via a rotating shaft. A placement groove is provided at the upper end of the partition and the position corresponding to the shielding door. A sealing door is rotatably connected to the front end of the chamber via a hinge. When drying different samples with different drying times, samples with longer drying times are placed behind the shielding door. When the drying time of some samples is reached, the operator opens the sealing door and removes the dried samples. Samples that have not yet reached their drying time are not directly exposed to the air, thus ensuring drying quality.

[0003] After investigation and analysis, the patent has the following drawbacks in actual use: The device uses a fixed placement slot structure inside both of its double-layer cavities, without designing differentiated load-bearing schemes for materials of different shapes. For thin, flat materials, the fixed placement slots cannot achieve layered flat laying, and the stacking of materials leads to uneven heating and low drying efficiency. For large-sized block materials, the placement slot size is fixed, and the load-bearing space cannot be adjusted according to the size of the material, making it difficult to put large-sized materials in.

[0004] In summary, this application proposes a double-layer vacuum drying oven to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a double-layer vacuum drying oven that can solve the problem that both layers of the oven use a fixed placement slot structure and do not have a differentiated load-bearing scheme designed for materials of different shapes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-layer vacuum drying oven, comprising: The vacuum drying oven has an upper drying chamber and a lower drying chamber on its front side. The upper placement component is set on the upper drying chamber. The upper placement component includes a placement frame, a fixing plate, a slide rail and a slide groove. The bottom of the placement frame is provided with two sets of fixing plates that are symmetrically distributed. The top of the fixing plate is fixedly installed with a slide rail. The bottom of the placement frame is provided with a slide groove corresponding to the slide rail. The lower placement component is located on the lower drying chamber. The lower placement component includes a disc, a bracket, and a second placement frame. Two sets of brackets are fixedly installed on the top of the disc and are symmetrically distributed. The second placement frame is located on the top of the bracket.

[0007] Preferably, a controller is fixedly installed on one side of the vacuum drying chamber; the controller can independently control the vacuum degree, heating temperature and heating time of the upper drying chamber and the lower drying chamber of the vacuum drying chamber, so as to realize the precise adjustment of the double-layer drying parameters, adapt to the drying needs of different materials, eliminate the need for frequent manual switching operations, and improve the automation level of the equipment.

[0008] Preferably, the upper placement component further includes magnetic blocks. There are multiple sets of placement frames arranged longitudinally. Two sets of fixing plates are respectively fixedly installed on the opposite side walls of the upper drying chamber. The slide rail is slidably installed inside the slide groove. Two sets of magnetic blocks are fixedly installed on the front side of the placement frame and are symmetrically distributed. The magnetic blocks are attracted to the fixing plates. Multiple sets of placement frames can realize the layered placement of flat materials, increasing the drying capacity per batch. The sliding cooperation between the slide rail and the slide groove facilitates the pushing, pulling and placing of the placement frames. The attraction and fixation of the magnetic blocks and the fixing plates can prevent the placement frames from shifting due to vibration during the drying process, ensuring that the flat materials are heated evenly.

[0009] Preferably, the placement frame adopts a hollow mesh structure; this structure can ensure that the hot airflow in the upper drying chamber penetrates the material evenly, accelerate the evaporation of moisture on the material surface, and at the same time avoid the accumulation of material residue, reduce cleaning difficulty, and improve drying efficiency.

[0010] Preferably, the lower placement assembly further includes a motor, a second sliding groove, a U-shaped magnetic plate, and iron blocks. A groove is formed at the bottom of the lower drying chamber, and a motor is fixedly installed at the bottom of the groove. The motor's output shaft is fixedly installed to the bottom of the disc. A second sliding groove is formed at the top of the support, and a U-shaped magnetic plate is embedded inside the second sliding groove. Two sets of iron blocks are fixedly installed at the bottom of the second placement frame and are symmetrically distributed. The iron blocks are slidably installed inside the second sliding groove and are attracted to the U-shaped magnetic plate. The motor can drive the disc and the second placement frame to rotate slowly, ensuring that large-sized materials are heated evenly on all sides, solving the problem of incomplete drying of materials in certain areas caused by traditional fixed placement. The sliding cooperation between the second sliding groove and the iron blocks facilitates adjustment of the position of the second placement frame, adapting to large materials of different sizes. The attraction between the U-shaped magnetic plate and the iron blocks ensures that the second placement frame is stable and does not wobble during rotation.

[0011] Preferably, the vacuum drying oven has two sets of sealing doors hinged to the front side and located in front of the upper and lower drying chambers; the contact parts between the sealing doors and the vacuum drying oven are provided with silicone rubber sealing rings, which can form independent sealed spaces for the upper and lower drying chambers after closing, ensuring stable vacuum in the chambers and avoiding a decrease in drying efficiency due to poor sealing. At the same time, the sealing rings have good aging resistance, reducing the cost of frequent replacement.

[0012] Preferably, stainless steel heating tubes are embedded in the inner walls of both the upper and lower drying chambers, and vacuum sensors and temperature sensors are installed in each chamber. The heating tubes can quickly increase the temperature inside the chamber, and the temperature sensors work together to achieve closed-loop temperature control. The vacuum sensors monitor the vacuum level of the chamber in real time.

The motor can drive the disc and the second placement frame to rotate slowly, so that large-sized materials are heated evenly on all sides, solving the problem of incomplete drying of materials in some areas caused by traditional fixed placement. The sliding cooperation between the second sliding groove and the iron block makes it easy to adjust the position of the second placement frame to adapt to large materials of different sizes. The adsorption of the U-shaped magnetic plate and the iron block can ensure that the second placement frame is stable and does not shake during rotation.

Therefore, they should not be construed as limitations on this utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a double-layer vacuum drying oven, including a vacuum drying oven 1, an upper placement assembly and a lower placement assembly. The front side of the vacuum drying oven 1 has an upper drying chamber 3 and a lower drying chamber 4. The upper placement assembly is disposed on the upper drying chamber 3 and includes a placement frame 5, a fixing plate 6, a slide rail 7 and a slide groove 8. The bottom of the placement frame 5 is provided with two sets of fixing plates 6 and they are symmetrically distributed. The top of the fixing plate 6 is fixedly installed with a slide rail 7. The bottom of the placement frame 5 is provided with a slide groove 8 corresponding to the slide rail 7. The lower placement assembly is disposed on the lower drying chamber 4 and includes a disc 10, a support 12 and a second placement frame 13. The top of the disc 10 is fixedly installed with two sets of support 12 and they are symmetrically distributed. The top of the support 12 is provided with a second placement frame 13.

[0020] Furthermore, a controller 2 is fixedly installed on one side of the vacuum drying chamber 1; the controller 2 can independently control the vacuum degree, heating temperature and heating time of the upper drying chamber 3 and the lower drying chamber 4 of the vacuum drying chamber 1, so as to realize the precise adjustment of the double-layer drying parameters, adapt to the drying needs of different materials, and improve the automation level of the equipment without the need for frequent manual switching operations.

[0021] Furthermore, the upper placement component also includes magnetic blocks 9. There are multiple sets of placement frames 5 arranged longitudinally. Two sets of fixing plates 6 are respectively fixedly installed on the opposite side walls of the upper drying chamber 3. The slide rail 7 is slidably installed inside the slide groove 8. Two sets of magnetic blocks 9 are fixedly installed on the front side of the placement frame 5 and are symmetrically distributed. The magnetic blocks 9 are attracted to the fixing plates 6. After all the placement frames 5 are filled, the placement frames 5 are pushed along the slide rail 7 and completely enter the upper drying chamber 3. Then, the magnetic blocks 9 on the front side of the placement frame 5 are attracted and fixed to the fixing plates 6. Multiple sets of placement frames 5 can realize the layered placement of flat materials, increasing the drying capacity per batch. The sliding cooperation between the slide rail 7 and the slide groove 8 facilitates the pushing, pulling and placing of the placement frames 5. The attraction and fixation of the magnetic blocks 9 and the fixing plates 6 can prevent the placement frames 5 from shifting due to vibration during the drying process, ensuring that the flat materials are heated evenly.

[0022] Furthermore, the placement frame 5 adopts a hollow mesh structure; this structure can ensure that the hot airflow in the upper drying chamber 3 penetrates the material evenly, accelerates the evaporation of moisture on the material surface, and at the same time avoids the accumulation of material residue, reduces cleaning difficulty, and improves drying efficiency.

[0023] Furthermore, the lower placement assembly also includes a motor 11, a second sliding groove 14, a U-shaped magnetic plate 15, and iron blocks 16. A groove is formed at the bottom of the lower drying chamber 4, and a motor 11 is fixedly installed at the bottom of the groove. The output shaft of the motor 11 is fixedly installed at the bottom of the disc 10. A second sliding groove 14 is formed at the top of the support 12, and a U-shaped magnetic plate 15 is embedded inside the second sliding groove 14. Two sets of iron blocks 16 are fixedly installed at the bottom of the second placement frame 13 and are symmetrically distributed. The iron blocks 16 are slidably installed inside the second sliding groove 14 and are attracted to the U-shaped magnetic plate 15. Large-sized materials are placed stably in the second placement frame 13. If the material size is large, the position of the second placement frame 13 on the support can be adjusted by the sliding cooperation between the iron blocks 16 at the bottom of the second placement frame 13 and the second sliding groove 14 at the top of the support 12, so that the material is placed in the center. After the material is placed, confirm that the iron blocks 16 at the bottom of the second placement frame 13 and the U-shaped magnetic plate 15 are aligned. The U-shaped magnetic plate 15 completely adsorbs the material, and the motor 11 can drive the disc 10 and the second placement frame 13 to rotate slowly, so that the large-sized material is heated evenly on all sides, solving the problem of incomplete drying of materials in some areas caused by traditional fixed placement. The sliding fit between the second slide groove 14 and the iron block 16 makes it easy to adjust the position of the second placement frame 13 to adapt to large materials of different sizes. The adsorption between the U-shaped magnetic plate 15 and the iron block 16 ensures that the second placement frame 13 is stable and does not shake during rotation.

[0024] Secondly, two sets of sealing doors 17 are hinged to the front of the vacuum drying oven 1 and are located in front of the upper drying chamber 3 and the lower drying chamber 4. The contact parts between the sealing doors 17 and the vacuum drying oven 1 are equipped with silicone rubber sealing rings. When closed, the upper drying chamber 3 and the lower drying chamber 4 can form independent sealed spaces, ensuring stable vacuum in the chambers and avoiding a decrease in drying efficiency due to poor sealing. At the same time, the sealing rings have good aging resistance, reducing the cost of frequent replacement.

[0025] Secondly, stainless steel heating tubes are embedded in the inner walls of the upper drying chamber 3 and the lower drying chamber 4, and vacuum sensors and temperature sensors are installed in the chambers. The heating tubes can quickly increase the temperature in the chambers, and the temperature sensors work together to achieve closed-loop temperature control. The vacuum sensors monitor the vacuum level of the chambers in real time.

[0026] Working principle: The material to be dried is evenly spread in placement frame 1 5. After all placement frames 1 5 are filled, they are pushed along slide rail 7 and fully enter the upper drying chamber 3. Then, they are fixed to the fixing plate 6 by the magnetic block 9 on the front of placement frame 1 5 to prevent the placement frames from shifting during the drying process. The upper sealing door 17 is closed. Larger materials are then placed stably in placement frame 2 13. If the material is large, the position of placement frame 2 13 on the support can be adjusted by the sliding engagement of the iron block 16 at the bottom of placement frame 2 13 and the slide rail 2 14 at the top of the support 12, so that the material is placed in the center. After the material is placed, confirm that the iron block 16 at the bottom of placement frame 2 13 and the slide rail 2 14 at the top of the support 12 are aligned. The magnetic suction plate 15 is fully adsorbed, the lower sealing door 17 is closed, and the lower drying chamber is sealed. The upper drying chamber 3 and the lower drying chamber 4 are started by the controller 2 to perform vacuum drying on the material. At the same time, the motor 11 can be started to drive the placement frame 13 on the disc 10 to rotate, so that the material follows the rotation. When the drying time reaches the preset value, the upper and lower heating systems are turned off by the controller 2, the vacuum valve is opened to slowly release pressure, the upper sealing door 17 is opened, and the placement frame 5 is pulled out along the slide rail 7. The dried flat material is taken out in sequence. The lower sealing door 17 is opened, and the placement frame 13 is pulled out along the slide groove 14. The dried material is taken out. After the material is taken out, the adsorption status between the placement frame 13 and the support 12 is checked, the inside of the placement frame 13 is cleaned, and the lower layer material removal is completed.
