Their high-efficiency drying capacity and strict protection of material quality make vacuum drying ovens an indispensable part of the manufacturing of many precision products.

[0003] Vacuum drying ovens, as a paradigm of precision drying technology, are meticulously designed for processing heat-sensitive, easily decomposed, and easily oxidized substances. Their core function lies in creating a highly controllable vacuum environment, effectively isolating materials from direct contact with external oxygen and heat sources, thus protecting them from oxidation and thermal degradation. Furthermore, the equipment features a flexible inert gas filling function, allowing users to freely connect and fill different types of gas sources according to the characteristics of the materials, further expanding its application range. Even materials with complex compositions and stringent requirements can achieve rapid and safe drying.

[0004] However, the diversity of materials and their size differences during vacuum drying pose challenges to the design of storage racks. Traditional vacuum drying oven storage racks often adopt a fixed spacing design, which is difficult to adapt to the flexible placement of materials of different sizes, resulting in low space utilization. Therefore, a vacuum drying oven storage rack is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] like Figure 1-4 As shown, a vacuum drying oven rack includes a rack body 101; multiple sets of first serrated racks 102 and fixed racks 103 are symmetrically fixedly connected to the inner wall of the rack body 101; sliding columns 104 are symmetrically slidably connected to the inner side of the fixed racks 103; a pressure plate 105 is fixedly connected to the lower end of the sliding column 104; a spring 106 is provided between the pressure plate 105 and the fixed rack 103; the two ends of the spring 106 are fixedly connected to the fixed rack 103 and the pressure plate 105 respectively; a placement plate 107 is attached to the lower end of the pressure plate 105; second serrated racks 108 are fixedly connected to both ends of the placement plate 107; the second serrated racks 108 mesh with the first serrated racks 102; [Operating] During the process, the staff adjusts the distance between multiple sets of placement plates 107 according to the size of the material, and then places the placement plates 107 between the pressure plate 105 and the first sawtooth frame 102. Through the elastic characteristics of the spring 106, the pressure plate 105 moves downward. The downward movement of the pressure plate 105 compresses the placement plates 107, thereby causing the second sawtooth frame 108 to mesh with the first sawtooth frame 102. This step, by adjusting the distance between multiple sets of placement plates 107 according to the size of the material, allows for flexible adjustment of the inner space of the shelf body 101. At the same time, the meshing between the placement plates 107 and the first sawtooth frame 102 reduces loosening and makes the material placed on the placement plates 107 more stable.

[0025] like Figure 2, Figure 5 As shown, a dust collection box 201 is provided at the lower end of the inner side of the shelf body 101; the two ends of the dust collection box 201 are slidably connected to limit blocks 203; the upper end of the limit block 203 is fixedly connected to a block 202; the lower end of the connecting block 202 is fixedly connected to a scraper block 204; the scraper block 204 is located inside the dust collection box 201 and fits against the dust collection box 201; a pull rod 205 is fixedly connected to the end of the connecting block 202; during operation, the dust collection box 201... 01. Dust is collected, and then the staff pulls the lever 205, which moves the connecting block 202. In turn, the connecting block 202 moves the scraper block 204 and the limiting block 203. As the scraper block 204 moves, it scrapes the dust inside the dust collection box 201. In this step, the dust is collected by the dust collection box 201, and the scraper block 204 is moved by the lever 205 to clean the dust collection box 201, thereby improving the cleaning efficiency.

[0026] like Figure 2-3 As shown, a pull block 301 is fixedly connected to the upper end of the sliding column 104. During operation, the operator pulls the pull block 301, which in turn moves the sliding column 104 upward. At the same time, the sliding column 104 moves the pressure plate 105 upward. Then, the operator places the placement plate 107 between the pressure plate 105 and the first sawtooth frame 102. Then, the operator releases the pull block 301. Due to the elasticity of the spring 106, the first sawtooth frame 102 and the second sawtooth frame 108 mesh with each other. This step, by pulling the pull block 301 upward, makes it more convenient to place the placement plate 107, and makes it faster for the operator to adjust the distance between multiple sets of placement plates 107, thereby improving the operator's work efficiency.

[0027] like Figure 2 , Figure 4 As shown, the placement plate 107 is provided with multiple sets of ventilation holes 401 inside; during operation, the ventilation holes 401 make the air flow inside the device better, thereby improving the air circulation during the drying process and thus improving the drying efficiency.

[0028] like Figure 1 As shown, an airtight door 501 is rotatably connected to the outer side of the shelf body 101. During operation, when taking or placing materials, the operator can rotate the airtight door 501. This step allows the device to be partially opened through the airtight door 501, effectively maintaining a dry environment and enhancing the safety and durability of the equipment.

[0029] like Figure 1As shown, a pull handle 601 is fixedly connected to the middle of the airtight door 501; during operation, the airtight door 501 is rotated by pulling the handle 601. This step makes it more convenient for the operator to rotate the airtight door 501 by pulling the handle 601.

[0030] like Figure 1 As shown, the lower end of the shelf body 101 is provided with multiple sets of brake wheels 701; this step makes it more convenient for staff to move the device by means of brake wheels 701.

[0031] Working principle: During operation, the operator adjusts the distance between multiple sets of placement plates 107 according to the size of the material. Then, the placement plates 107 are placed between the pressure plate 105 and the first sawtooth frame 102. Due to the elasticity of the spring 106, the pressure plate 105 moves downwards, pressing the placement plates 107 and causing the second sawtooth frame 108 to mesh with the first sawtooth frame 102. This step, by adjusting the distance between the multiple sets of placement plates 107 according to the size of the material, allows for flexible adjustment of the inner space of the shelf body 101. Simultaneously, the meshing between the placement plates 107 and the first sawtooth frame 102... This design ensures greater stability and reduces loosening of the material on the placement plate 107. During operation, dust is collected by the dust collection box 201. Then, the operator pulls the lever 205, which moves the connecting block 202. This, in turn, moves the scraper block 204 and the limiting block 203. As the scraper block 204 moves, it scrapes away dust from the inside of the dust collection box 201. This process, where the dust collection box 201 is used to collect dust and the scraper block 204 is used to clean it via the lever 205, improves cleaning efficiency. The operator pulls the lever 301, which in turn moves the sliding column 104 upward, simultaneously causing the pressure plate 105 to move upward. The operator then places the placement plate 107 between the pressure plate 105 and the first sawtooth frame 102. Releasing the lever 301 allows the elasticity of the spring 106 to engage the first sawtooth frame 102 and the second sawtooth frame 108. This upward movement of the lever 301 facilitates the placement of the placement plate 107, making it easier for the operator to adjust the distance between multiple placement plates 107, thus improving work efficiency. During operation, the ventilation holes 401 improve airflow within the device, enhancing air circulation during the drying process and thus increasing drying efficiency. When loading or unloading materials, operators can rotate the airtight door 501. This partially opens the device, effectively maintaining the drying environment and enhancing the equipment's safety and durability. Pulling the handle 601 rotates the airtight door 501, making it easier for operators to do so. The brake wheels 701 further facilitate movement of the device.

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.
