Description

Technical Field

[0001] This utility model relates to the field of heat treatment and drying technology, and in particular to a vacuum oven that facilitates uniform heating. Background Technology

[0002] Vacuum ovens are widely used in processes such as material dehydration, curing, and degassing because they can heat heat-sensitive and easily oxidized materials in low-oxygen or oxygen-free environments. To ensure that all parts of the material are heated evenly, existing vacuum ovens that facilitate uniform heating usually use a multi-layer shelf structure to support the material, and achieve temperature uniformity by optimizing the thermal conductivity of the shelves (such as using materials such as aluminum alloy and stainless steel) in conjunction with a multi-zone heating system.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In existing vacuum ovens that facilitate uniform heating, the design of multi-layer shelves often uses heavy metal materials (such as thick-walled stainless steel or solid aluminum alloy). Loading and unloading materials requires manual lifting or multiple people to move the shelves, which is laborious. In addition, the shelf spacing is cumbersome and difficult to adapt to materials of different heights, resulting in low efficiency and applicability. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing vacuum ovens that facilitate uniform heating have thick and heavy shelves, which makes loading and unloading materials laborious and the operation is cumbersome and inefficient in terms of adapting to materials of different heights. Therefore, we propose a vacuum oven that facilitates uniform heating.

[0005] To achieve the above objectives, this application adopts the following technical solution: a vacuum oven that facilitates uniform heating, comprising a box body: a door is provided at the front end of the box body, and mounting brackets are provided at the four corners inside the box body. The surface of the mounting brackets is provided with slots, and the number of slots is multiple and arranged longitudinally at equal intervals. Placement blocks are installed inside each slot, and the number of placement blocks is multiple and arranged longitudinally. A shelf is installed on the top of each placement block, and the edge of the shelf is provided with anti-slip silicone strips.

[0006] Preferably, the shelf uses carbon fiber composite board as the base material and has an embedded copper heat dissipation network inside.

[0007] Preferably, the shelf has multiple weight-reducing holes at its center.

[0008] Preferably, both ends of the placement block near the inner wall of the box are fixedly provided with hanging plates, and the placement block is fixed inside the slot by the hanging plates.

[0009] Preferably, the front end of the placement block is provided with a groove, a fixing cylinder is fixed inside the groove, a movable rod is slidably installed inside the fixing cylinder, a pull rod is fixed on the surface of the movable rod inside the fixing cylinder, and fixing holes matching the movable rod are provided on both sides of the shelf.

[0010] Preferably, a spring is fitted onto the surface of the fixed cylinder, one end of the spring is fixed to the inside of the groove, the pull rod extends to the outside of the fixed cylinder and is higher than the spring, and the pull rod is located at the spring pitch.

[0011] Preferably, the surface of the fixed cylinder is provided with a guide groove, and the pull rod slides inside the guide groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, anti-slip silicone strips effectively prevent materials from sliding on the shelf, ensuring the stability of the materials during heating. The shelf uses carbon fiber composite board as the base material and embeds a copper heat dissipation network inside, which not only reduces the overall weight but also improves the thermal conductivity, ensuring that the materials are heated evenly. In addition, multiple weight-reducing holes in the center of the shelf further reduce the weight of the shelf without affecting its structural strength and load-bearing capacity. The height of the shelf can be flexibly adjusted by adjusting the position of the placement block in the slot of the mounting frame to accommodate materials of different heights. Through the above design, there is no need for manual lifting or multiple people to move the shelf, which greatly improves the convenience of operation and the efficiency of use.

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a vacuum oven for easy and uniform heating, comprising a body 1; a door 2 is provided at the front end of the body 1, and mounting brackets 3 are provided at the four corners inside the body 1. The surface of the mounting brackets 3 has multiple slots 4 arranged longitudinally at equal intervals. Placement blocks 5 are installed on the opposite sides of each slot 4, and shelves 6 are installed on the top of each placement block 5. Anti-slip silicone strips are provided on the edges of the shelves 6. The shelves 6 use carbon fiber composite board as the base material and have embedded copper heat dissipation pipes. Multiple weight-reducing holes 7 are provided in the center of the shelves 6. The anti-slip silicone strips effectively prevent materials from slipping on the shelves. The shelf 6 slides upwards, ensuring the stability of the material during heating. The shelf 6 uses carbon fiber composite board as the base material and has an embedded copper heat dissipation network, which not only reduces the overall weight but also improves the thermal conductivity, ensuring that the material is heated evenly. In addition, multiple weight-reducing holes 7 set in the center of the shelf 6 further reduce the weight of the shelf 6 without affecting its structural strength and load-bearing capacity. The height of the shelf 6 can be flexibly adjusted by adjusting the position of the placement block 5 in the slot 4 of the mounting frame 3 to accommodate materials of different heights. Through the above design, there is no need for manual lifting or multiple people to move the shelf 6, which greatly improves the convenience of operation and the efficiency of use.

[0022] Reference Figure 4 As shown in this implementation scheme: both ends of the placement block 5 near the inner wall of the box 1 are fixedly provided with hanging plates 8. The placement block 5 is fixed inside the slot 4 by the hanging plates 8. Through the cooperation between the hanging plates 8 and the slot 4, the placement block 5 can be quickly installed and removed on the mounting frame 3, which makes it convenient for users to adjust the height of the shelf 6 or perform maintenance and cleaning work, further improving the practicality and flexibility of the equipment.

[0023] Reference Figure 4As shown in this embodiment: a groove 9 is provided at the front end of the placement block 5, a fixing cylinder 10 is fixed inside the groove 9, a movable rod 11 is slidably installed inside the fixing cylinder 10, and a pull rod 12 is fixed on the surface of the movable rod 11 inside the fixing cylinder 10. Fixing holes 13 matching the movable rod 11 are provided on both sides of the shelf 6. A spring 14 is sleeved on the surface of the fixing cylinder 10, one end of the spring 14 is fixed inside the groove 9, and the pull rod 12 extends to the outside of the fixing cylinder 10 and is higher than the spring 14. The pull rod 12 is located at the pitch of the spring 14. Through the cooperation of the pull rod 12 and the fixing hole 13, the shelf is secured. 6. The quick fixing and disassembly of the placement block 5 is achieved by simply pulling the pull rod 12 to move the movable rod 11 into the fixing cylinder 10, then placing the shelf 6, and then releasing the pull rod 12. The spring 14's rebound force pushes the pull rod 12 to insert the movable rod 11 into the fixing hole 13, thus completing the installation and fixing of the shelf 6. Conversely, pulling the movable rod 11 out of the fixing hole 13 will disassemble the shelf 6. This design is not only simple and quick to operate, but also greatly improves the stability of the shelf 6 installation, preventing the shelf 6 from shaking or falling off during heating, and further ensuring the uniformity and safety of material heating.

[0024] Reference Figure 4 As shown in this embodiment: the surface of the fixed cylinder 10 is provided with a guide groove 15, and the pull rod 12 slides inside the guide groove 15. The guide groove 15 guides the pull rod 12, ensuring the stability and accuracy of the pull rod 12 during movement, avoiding the pull rod 12 from deviating from the predetermined path or getting stuck, and further improving the smoothness and convenience of installing and disassembling the shelf 6.

[0025] Working Principle: By setting anti-slip silicone strips, users can effectively prevent materials from sliding on the shelf 6, ensuring the stability of the materials during heating. The shelf 6 uses carbon fiber composite board as the base material, with an embedded copper heat dissipation network, which not only reduces the overall weight but also improves thermal conductivity, ensuring uniform heating of the materials. Furthermore, multiple weight-reducing holes 7 in the center of the shelf 6 further reduce its weight without affecting its structural strength and load-bearing capacity. The height of the shelf 6 can be flexibly adjusted by adjusting the position of the placement block 5 in the slot 4 of the mounting frame 3 to accommodate materials of different heights. This design eliminates the need for manual lifting or multiple people to move the shelf 6, greatly improving operational convenience and efficiency. The cooperation between the hanging plate 8 and the slot 4 enables quick installation and removal of the placement block 5 on the mounting frame 3, facilitating height adjustment or maintenance and cleaning of the shelf 6, further enhancing the practicality and flexibility of the equipment. The design, through the cooperation of the pull rod 12 and the fixing hole 13, enables the quick fixing and disassembly of the shelf 6 on the placement block 5. The user only needs to pull the pull rod 12 to move the movable rod 11 into the fixing cylinder 10, then place the shelf 6, and then release the pull rod 12. The spring 14's rebound force pushes the pull rod 12 to drive the movable rod 11 into the fixing hole 13, thus completing the installation and fixing of the shelf 6. Conversely, pulling the movable rod 11 out of the fixing hole 13 will disassemble the shelf 6. This design is not only simple and quick to operate, but also greatly improves the stability of the shelf 6 installation, avoiding the shaking or falling off of the shelf 6 during heating, and further ensuring the uniformity and safety of material heating. The guide groove 15 guides the pull rod 12, ensuring the stability and accuracy of the pull rod 12 during movement, avoiding the pull rod 12 from deviating from the predetermined path or getting stuck, further improving the smoothness and convenience of the shelf 6 installation and disassembly.
