Description

Technical Field

[0001] This utility model belongs to the field of vacuum drying oven technology, specifically relating to a flat-plate vacuum drying oven. Background Technology

[0002] A flat-plate vacuum drying oven is a device used in laboratories and industry, primarily for drying samples under vacuum conditions. It reduces the internal pressure by creating a vacuum, allowing samples to dry rapidly at a lower temperature. Simultaneously, a heating system maintains the set temperature, ensuring the efficiency and effectiveness of the drying process.

[0003] In the prior art, since the flat plate inside the flat plate vacuum drying oven is usually fixed, the space inside the vacuum drying oven cannot be flexibly adjusted during use. When the volume and height of the material to be dried are large, it is impossible to put the material into the oven. Furthermore, the material on the flat plate cannot be rotated, resulting in inconsistent drying levels between the bottom and top of the material. Therefore, we propose a flat plate vacuum drying oven to solve the above-mentioned problems. Utility Model Content

[0027] 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.

[0028] Please see Figures 1-8This utility model provides a flat vacuum drying oven, including a vacuum drying component 1, a lifting component 2 inside the vacuum drying component 1, a flipping component 3 on the vacuum drying component 1, a moving component 5 on the flipping component 3, and a driving component 4 on the vacuum drying component 1, and the driving component 4 is connected to the lifting component 2.

[0029] The vacuum drying assembly 1 includes a drying chamber body 11 and a placement plate 13. Two placement plates 13 are provided inside the drying chamber body 11, and two lifting assemblies 2 are provided between the two placement plates 13 and the inner wall of the drying chamber body 11.

[0030] The lifting assembly 2 includes a fixing member A 21, which is located inside the drying chamber body 11. A screw A 24 is located inside the drying chamber body 11 and extends through to the surface of the drying chamber body 11. Two movable parts 23 are threaded on the screw A 24 and are symmetrically arranged. A fixing member B 22 is located directly above the fixing member A 21 and is connected to the placement plate 13. The fixing member A 21 and the movable parts 23 are hinged by a hinge B 26, and the fixing member B 22 and the movable parts 23 are hinged by a hinge A 25.

[0031] Specifically, when drying the items to be dried, since the volume of the items to be dried is usually difficult to fix, in order to adapt to different heights of the items to be dried, the A screw 24 can be rotated to control the two moving parts 23 to move closer or further apart. When the two moving parts 23 move closer to each other, since the height position of the moving parts 23 and the A screw 24 remains unchanged, and the moving parts 23 are hinged to the A fixed part 21 and the B fixed part 22 respectively through the A hinge 25 and the B hinge 26, the placing plate 13 will be moved up and down by the A hinge 25 and the B hinge 26 respectively, thereby increasing or decreasing the distance between the two placing plates 13, so that it is easier to put the items to be dried into the drying chamber body 11.

[0032] Furthermore, in order to keep the interior of the drying chamber body 11 closed when the screw A 24 rotates, the screw A 24 is only provided with a threaded structure on the inner surface of the drying chamber body 11, while the part that penetrates the drying chamber body 11 is a smooth round rod structure, and a leak-proof rubber ring should be provided on the surface of this structure, so as to keep the interior of the drying chamber body 11 closed.

[0033] In this embodiment, the vacuum drying assembly 1 also includes a sealing door 12 and a control panel 14, both of which are mounted on the drying chamber body 11.

[0034] Specifically, during use, the operation of the drying chamber body 11 and other devices can be controlled through the control panel 14, while the interior of the drying chamber body 11 can be sealed through the sealing door 12, thus facilitating the drying operation.

[0035] In this embodiment, the flipping assembly 3 includes a snap-fit ​​component 31, an A gear 33, a B gear 34, and a C gear 35. The snap-fit ​​component 31 is disposed on the placement plate 13. The A gear 33, B gear 34, and C gear 35 are all rotatably disposed on the snap-fit ​​component 31. The B gear 34 meshes with the A gear 33 and the C gear 35 respectively. The flipping assembly 3 also includes an A motor 32, a rotating shaft 36, and an arc-shaped component 37. The A motor 32 is disposed on the snap-fit ​​component 31, and the output end of the A motor 32 is connected to the A gear 33. Multiple rotating shafts 36 are disposed on the A gear 33, B gear 34, and C gear 35 respectively. Multiple arc-shaped components 37 are disposed on the surface of the rotating shaft 36.

[0036] Specifically, when drying certain materials, it is necessary to turn them over to ensure more uniform drying. This can be achieved by attaching the clip 31 to the placement plate 13, and by running motor A 32 to drive gear A 33 to rotate, which in turn drives gear B 34 to rotate in reverse and gear C 35 to rotate in the forward direction. Rotating shafts 36 are provided on gears A 33, B 34, and C 35. These rotating shafts 36 rotate, and arc-shaped parts 37 are provided on the rotating shafts 36 connected to gears A 33 and C 35 in the forward direction, and on the rotating shaft 36 connected to gear B 34 in the reverse direction. The rotation of these three parts turns over the material to be dried, thereby accelerating the drying process. Motor A 32 can be a high-temperature and vacuum-resistant stepper motor, model KVM2851, from Chengdu Jinshili Technology Co., Ltd.

[0037] In this embodiment, the drive assembly 4 includes a chain 43, an A-type toothed sprocket 44, and a B-type toothed sprocket 45. The A-type toothed sprocket 44 and the B-type toothed sprocket 45 are respectively connected to two A-type screws 24, and the chain 43 connects the A-type toothed sprocket 44 and the B-type toothed sprocket 45. The drive assembly 4 also includes an extension plate 41 and a B-type motor 42. The extension plate 41 is disposed on the drying oven body 11, and the B-type motor 42 is disposed on the extension plate 41, and the output end of the B-type motor 42 is connected to the B-type toothed sprocket 45.

[0038] Specifically, in order to drive the two A screws 24 to rotate simultaneously, the two A screws 24 can be connected to the A sprocket 44 and the B sprocket 45 respectively, and the A sprocket 44 and the B sprocket 45 can be connected by the chain 43. At this time, by running the B motor 42, the B sprocket 45 can be driven to rotate, and then the A sprocket 44 can be driven to rotate by the chain 43, so that the two A screws 24 can rotate synchronously.

[0039] In this embodiment, the moving component 5 includes a D gear 51, an E gear 52, an F gear 53, a drive shaft 54, and a rack 55. Both the D gear 51 and the E gear 52 are rotatably mounted on the snap-fit ​​member 31. The D gear 51 meshes with the A gear 33 and the E gear 52 respectively. The drive shaft 54 ​​is mounted on the E gear 52 and extends through the surface of the snap-fit ​​member 31. The F gear 53 is mounted on the drive shaft 54. The rack 55 is located at the bottom of the placement plate 13. It meshes with the rack 55; the moving component 5 also includes a limiting member 56 and a B screw 57. The surface of the plate 13 is provided with an A connecting groove 58, and the surface of the snap-fit ​​member 31 is provided with a B connecting groove 59. The B screw 57 is rotatably mounted on the snap-fit ​​member 31. The B screw 57 includes an upper threaded rod and a lower sliding rod. The limiting member 56 is threadedly connected to the upper threaded rod of the B screw 57. The limiting member 56 is located in the B connecting groove 59 and the A connecting groove 58.

[0040] Specifically, when turning the crops, in order to allow the locking member 31 to move and thus fully turn the material placed on the plate 13, both gear D 51 and gear E 52 can be set on the locking member 31. Gear D 51 meshes with gear A 33, and gear E 52 meshes with gear D 51. At this time, gear E 52 and gear F 53 are connected through the drive shaft 54, and gear F 53 meshes with rack 55. Thus, when motor A 32 is started, the entire turning assembly 3 can be moved simultaneously. In order to ensure that the locking member 31 can be stable... The fixed part is set on the placement plate 13, so the B screw 57 can be set on the snap fastener 31, and the limiting part 56 passes through the A connecting groove 58 at the bottom of the placement plate 13 and the B connecting groove 59 on the surface of the snap fastener 31 in sequence, and then passes through the slide bar at the lower part of the B screw 57 and is threadedly connected to the upper threaded rod. Since the limiting part 56 is slidably set inside the B connecting groove 59, by rotating the slide bar at the lower part of the B screw 57 to drive the upper threaded rod to rotate, the limiting part 56 can be inserted into the A connecting groove 58 and fixed, so that the snap fastener 31 can slide stably on the side of the placement plate 13.

[0041] Furthermore, after the snap-fit ​​component 31 is snapped onto the placement plate 13, the F gear 53 and rack 55 are first engaged. Since both B screws 57 are located below the A connecting groove 58, rotating the two B screws 57 allows the limiting component 56 to rise. The limiting component 56 then slides upward within the B connecting groove 59 and can be inserted into the A connecting groove 58. This ensures the snap-fit ​​component 31 is stably positioned, preventing it from shaking or falling off significantly when moved later.

[0042] The working principle and usage process of this utility model are as follows: When drying the material to be dried, the distance between the two lifting components 2 and the placing plates 13 can be adjusted by the driving component 4, so that materials of different volumes and heights can be placed inside the drying chamber body 11. The heat radiation after the upper and lower placing plates are heated accelerates the drying of the top and bottom layers of the material. When drying the material, it is necessary to turn the material over to speed up the drying process. At this time, the turning component 3 can be set on the placing plate 13, and the material on the placing plate 13 can be turned over by the turning component 3, thereby speeding up the drying process. The moving component 5 can make the turning component 3 stably set on the placing plate 13 and can drive the turning component 3 to move during the turning, so that the crop on the placing plate 13 can be turned over evenly.

[0043] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
