Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying oven technology; more specifically, it relates to a vacuum drying oven. Background Technology
[0002] A vacuum drying oven is a device that utilizes a vacuum environment for drying. Its main feature is the rapid evaporation of moisture at low temperatures by removing air and moisture from the chamber, thus protecting materials from high-temperature damage or oxidation. It is commonly used in the pharmaceutical, chemical, and electronics industries, and is particularly suitable for drying heat-sensitive or sensitive materials.
[0003] Currently, existing vacuum drying ovens involve first evacuating the air from the oven to create a vacuum, and then heating the material inside to dry it. This process can lead to uneven heating, affecting the final product's usability. Furthermore, the limited quantity of material that can be dried at one time results in slow drying efficiency, reducing the equipment's practicality. Additionally, the equipment cannot be adjusted to suit different material drying conditions, meaning it typically only works for one type of material, limiting its applicability. Therefore, a vacuum drying oven is urgently needed to address these issues. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vacuum drying oven to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a vacuum drying oven, comprising:
[0006] The drying oven body has a control panel fixedly connected to one end of one side of its outer surface, and a side door hinged to the other end of the outer surface of its outer surface. Heating plates are fixedly connected to both ends of the interior of the drying oven body. An air pump is installed at the top of one side of the interior of the drying oven body, and an air suction pipe is fixedly connected to the suction port of the air pump. One end of the air suction pipe passes through and extends out of the interior of the drying oven body. A one-way valve is fixedly connected inside the air suction pipe. A rotating structure is provided at the bottom of the interior of the drying oven body, and an adjustment structure is provided on the outside of the rotating structure.
[0007] The rotating structure includes a groove, and the groove is located at the bottom of the interior of the drying oven body;
[0008] The adjustment structure includes a rotating plate, and multiple sets of rotating plates are provided, with one end of each set of rotating plates fixedly connected to a rotating rod.
[0009] Preferably, the rotating structure further includes a drive motor. The drive motor is installed inside the groove, and the output shaft of the drive motor is connected to a first bevel gear by a bearing. A second bevel gear that meshes with the first bevel gear is provided inside the groove. A rotating rod is fixedly connected to the top of the second bevel gear, and the top of the rotating rod is connected to the top bearing inside the drying oven body. This design can control the rotating rod to rotate inside the drying oven body.
[0010] Preferably, a support column is fixedly connected inside the second bevel gear, and the bottom end of the support column is connected to the bearing at the bottom end of the inner wall of the groove. This design can support the second bevel gear and keep it rotating stably.
[0011] Preferably, the adjustment structure further includes a movable groove, and multiple sets of movable grooves are provided. The multiple sets of movable grooves are all opened inside multiple sets of rotating plates. The movable groove is connected to a lead screw by a bearing inside. The outer surface of the lead screw is threaded to a movable block. The top surface of the movable block is fixedly connected to a placement plate. This design can control the position of one end of the placement plate.
[0012] Preferably, the internal dimensions of the movable groove are adapted to the external dimensions of the movable block, which allows the movable block to move more stably inside the movable groove.
[0013] Preferably, one end of the lead screw passes through and extends out of the interior of the movable groove and is fixedly connected to a handle. This design allows the operator to easily control the rotation speed of the lead screw.
[0014] The technical effects and advantages of this utility model are as follows: By starting the drive motor, the first bevel gear can be driven to rotate. At this time, because the second bevel gear meshes with the first bevel gear, the second bevel gear and the rotating rod can be driven to rotate slowly. This design allows the material to rotate slowly inside the drying chamber, so that the material can be heated evenly from all sides. At the same time, a larger amount of material can be put in for drying at one time, improving the overall drying efficiency and improving the practicality of the equipment to a certain extent.
[0015] By turning the handle, the lead screw can be rotated, which in turn moves the movable block along the outer surface of the lead screw, causing the placement plate to move accordingly. Once the placement plate has moved to the appropriate position, turning the handle stops. This design allows for adjustment of the distance between the placement plate and the heating plate according to different material drying requirements, making the equipment suitable for various types of materials, thus enhancing its applicability and improving its overall suitability. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The drying oven involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Example 1
[0024] like Figures 1-4 As shown, this embodiment proposes a vacuum drying oven, comprising:
[0025] The drying oven body 1 has a control panel 2 fixedly connected to one end of one side of its outer surface, and a side door 3 hinged to the other end of the outer surface of the drying oven body 1. Heating plates 4 are fixedly connected to both ends inside the drying oven body 1. An air pump 5 is installed at the top of one side inside the drying oven body 1, and an air extraction pipe 6 is fixedly connected to the suction port of the air pump 5. One end of the air extraction pipe 6 passes through and extends out of the interior of the drying oven body 1. A one-way valve 7 is fixedly connected inside the air extraction pipe 6. A rotating structure 8 is provided at the bottom of the interior of the drying oven body 1, and an adjustment structure 9 is provided on the outside of the rotating structure 8. This design, under the action of the air pump 5 and the air extraction pipe 6, can draw the air out of the interior of the drying oven body 1, so that the interior of the drying oven body 1 forms a vacuum state.
[0026] The rotating structure 8 includes a groove 81, which is located at the bottom of the interior of the drying chamber body 1. The rotating structure 8 also includes a drive motor 82, which is installed inside the groove 81. The output shaft of the drive motor 82 is connected to a first bevel gear 83 by a bearing. A second bevel gear 84 that meshes with the first bevel gear 83 is provided inside the groove 81. A rotating rod 85 is fixedly connected to the top of the second bevel gear 84, and the top of the rotating rod 85 is connected to the top bearing inside the drying chamber body 1. This design allows the material to rotate slowly inside the drying chamber body 1, so that the material can be heated evenly from all sides, thus improving the drying effect.
[0027] The second bevel gear 84 is internally fixedly connected to a support column, and the bottom end of the support column is connected to the bearing at the bottom end of the inner wall of the groove 81. This design can support the second bevel gear 84, so that the second bevel gear 84 always maintains a meshing state with the first bevel gear 83.
[0028] Example 2
[0029] like Figure 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:
[0030] The adjustment structure 9 includes a rotating plate 91, and multiple sets of rotating plates 91 are provided. One end of each set of rotating plates 91 is fixedly connected to a rotating rod 85. The adjustment structure 9 also includes a movable groove 92, and multiple sets of movable grooves 92 are provided. Each set of movable grooves 92 is opened inside the multiple sets of rotating plates 91. A lead screw 93 is connected to the bearing inside the movable groove 92. A movable block 94 is threadedly connected to the outer surface of the lead screw 93. A placement plate 95 is fixedly connected to the top surface of the movable block 94. This design can adjust the distance between the placement plate 95 and the heating plate 4, so that the material is heated at different temperatures during the drying process, thereby enabling vacuum drying of various types of materials.
[0031] The internal dimensions of the movable slot 92 are adapted to the external dimensions of the movable block 94. One end of the lead screw 93 passes through and extends out of the interior of the movable slot 92 and is fixedly connected to a handle. This design allows the operator to easily control the rotation speed of the lead screw 93, so that the movable block 94 can move inward or outward along the outer surface of the lead screw 93, thereby controlling the movement position of the placement plate 95.
[0032] Working principle: When using the equipment, first open the side door 3. By turning multiple sets of handles, multiple sets of lead screws 93 can be driven to rotate. At this time, the movable block 94 can move along the outer surface of the lead screw 93, and drive the placement plate 95 to move accordingly. After the placement plate 95 moves to the appropriate position, stop turning the handles. This design can adjust the distance between the placement plate 95 and the heating plate 4, thereby controlling the temperature of the material on the surface of the placement plate 95. It can be adjusted according to different material drying conditions to make it suitable for various types of materials.
[0033] When using the equipment, first open the side door 3, place the materials to be dried onto the top surfaces of the multiple placement plates 95 in sequence, then close the side door 3, and start the vacuum pump 5 to suck out the air inside the drying chamber body 1 and discharge it to the outside through the vacuum pipe 6 until all the air inside the drying chamber body 1 is extracted, creating a vacuum inside the drying chamber body 1. Then start the drive motor 82, which will drive the first bevel gear 83 to rotate. At this time, because the second bevel gear 84 meshes with the first bevel gear 83, it will drive the second bevel gear 84 and the rotating rod 85 to rotate slowly, causing the multiple placement plates 95 to rotate slowly inside the drying chamber body 1. This design allows the materials on the surface of the placement plates 95 to rotate slowly inside the drying chamber body 1, ensuring that the materials are heated evenly inside the drying chamber body 1 and improving the drying effect. The above is the complete working principle of this practical device.
[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
