Description

Technical Field

[0001] This utility model relates to the field of isoleucine derivative technology, and in particular to an integrated vacuum drying and nitrogen protection box for isoleucine derivatives. Background Technology

[0002] The integrated vacuum drying and nitrogen protection chamber for isoleucine derivatives is a specialized device designed specifically for materials like isoleucine derivatives that are easily oxidized and sensitive to the drying environment. It integrates vacuum drying and nitrogen protection functions. In a sealed space, a vacuum pump first extracts air to create a vacuum environment, lowering the boiling point of moisture or solvents in the material to efficiently remove moisture. At the same time, high-purity nitrogen can be introduced to replace residual air in the chamber, creating an inert protective atmosphere to prevent isoleucine derivatives from oxidizing and deteriorating due to contact with oxygen during the drying process. Thus, while ensuring drying efficiency, it maximizes the protection of the chemical stability and biological activity of the material. It is widely used in the drying of these special derivatives in the fields of medicine and biochemical engineering.

[0003] The existing utility model patent with publication number CN211953468U discloses a gas introduction device for a vacuum drying oven. It describes a device that "uses a cylinder to drive the introduction pipe assembly installed in the drying oven to move up and down, expanding the range of nitrogen gas movement and allowing for more comprehensive and thorough contact with the objects in the trays, shortening drying time and improving work efficiency." While this solves the problem that "the drying oven has multiple trays from top to bottom, and the inert gas inlet is usually only one, making it impossible to fully contact the objects in the trays under the action of a vacuum pump; materials near the gas inlet are usually dried more thoroughly, resulting in uneven drying levels in the drying oven," the existing vacuum nitrogen-filled drying oven has significant operational limitations when feeding isoleucine derivative powder or granules. Due to the enclosed space inside the oven and the fixed shelf positions, the operator needs to... When a tray containing materials is fully pushed into the chamber through the door opening, the movement space for the hands and the tray is severely restricted by the door frame and the internal structure, making it difficult to accurately adjust the tray's position. Furthermore, isoleucine derivative powder or granules are lightweight, and slight shaking or collisions during tray pushing in the confined space can easily cause material to spill from the tray's edges. This spillage not only wastes raw materials but also remains in the chamber's crevices, increasing cleaning difficulty, especially in the corners. It can also contaminate the next batch of isoleucine derivatives due to oxidation and deterioration, affecting product purity. Additionally, obstructed visibility can cause the tray to be placed crookedly, affecting the uniformity of heating and nitrogen contact during drying, thus negatively impacting the drying effect. Therefore, an integrated vacuum drying and nitrogen protection chamber for isoleucine derivatives is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide an integrated vacuum drying and nitrogen protection chamber for isoleucine derivatives to address the aforementioned technical problems.

[0005] In order to solve the above-mentioned technical problems, the present invention solves the problem of obvious operational limitations when feeding isoleucine derivative powder or granules into a vacuum nitrogen-filled drying oven through the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated vacuum drying and nitrogen protection chamber for isoleucine derivatives, comprising: A vacuum nitrogen-filled drying oven, wherein a sealed door is hinged to one side of the front of the vacuum nitrogen-filled drying oven, a bottom plate is fixedly connected to the bottom of the inner wall of the vacuum nitrogen-filled drying oven, and two side plates are movably provided on the top of the bottom plate, and sliding guide rails are fixedly connected to the side walls of the side plates. The tray is placed between two sliding guide rails. Two through holes are opened on one side wall of the tray. A spring is connected between the inner wall of the through hole and the inner wall of the vacuum nitrogen-filled drying oven. Clamping and fixing components are provided between the two side plates and the bottom plate. Anti-detachment components are provided on the sliding guide rails.

[0007] As a preferred embodiment of the vacuum drying and nitrogen protection integrated box for isoleucine derivatives provided by this utility model, the clamping and fixing component includes an internal groove formed inside the base plate, and sliding holes are formed on both sides of the top of the internal groove. A slider is slidably connected to the inner wall of the sliding hole.

[0008] In a preferred embodiment of the integrated vacuum drying and nitrogen protection chamber for isoleucine derivatives provided by this utility model, the inner cavity of the built-in groove is connected to the inner cavity of the sliding hole, and the top end of the slider is fixedly connected to the side plate on the same side.

[0009] In a preferred embodiment of the vacuum drying and nitrogen protection integrated chamber for isoleucine derivatives provided by this utility model, a drive unit is installed in the middle of the inner wall of the built-in tank, and threaded rods are drivenly connected to the two output shafts of the drive unit, and the two threaded rods are symmetrically distributed.

[0010] In a preferred embodiment of the vacuum drying and nitrogen protection integrated chamber for isoleucine derivatives provided by this utility model, the driving unit is specifically a dual-axis motor, one end of the threaded rod is rotatably connected to the inner wall of the built-in groove, and the two threaded rods are respectively threadedly connected to two sliders.

[0011] As a preferred embodiment of the vacuum drying and nitrogen protection integrated box for isoleucine derivatives provided by this utility model, the anti-detachment component includes a through hole opened at the front end of the sliding guide rail, a protrusion slidably connected to the inner wall of the through hole, the protrusion being fixedly connected to the support plate, and an anti-detachment block provided on one side of the sliding guide rail.

[0012] In a preferred embodiment of the vacuum drying and nitrogen protection integrated box for isoleucine derivatives provided by this utility model, a groove is provided on one side of the inner wall of the through hole, and one end of the anti-detachment block slides through the surface of the sliding guide rail and engages with the inner cavity of the groove.

[0013] In a preferred embodiment of the vacuum drying and nitrogen protection integrated box for isoleucine derivatives provided by this utility model, multiple pulleys are embedded at the bottom and bottom ends of the inner wall of the sliding guide rail.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides an integrated vacuum drying and nitrogen protection chamber for isoleucine derivatives. Through the cooperation of springs and sliding guide rails, the pallet can be pushed out of the chamber when the sealed door is opened, significantly expanding the loading and unloading space. Operators no longer need to adjust the pallet within the narrow chamber, effectively preventing isoleucine derivative powder or granules from spilling due to operational constraints. It also reduces cleaning difficulties and cross-contamination risks caused by material residue in the chamber's gaps, improving the convenience and safety of the loading process. By incorporating clamping and fixing components, the drive unit rotates two threaded rods, causing the slider to slide within the sliding hole, thereby allowing the two side plates to move relative to each other, achieving a fixed clamping of the pallet. This fixing method is not only stable and reliable but also allows for flexible adjustment of the clamping force on the pallet, increasing the friction between the pallet and the sliding guide rail when the spring pushes the pallet out, thus achieving a slow push-out and ensuring that the pallet is not pulled out of the chamber by the sealed door during drying operations.

[0015] This utility model provides an integrated vacuum drying and nitrogen protection box for isoleucine derivatives. Utilizing a cleverly designed anti-detachment component, the protrusions on the tray slide within the through-holes of the sliding guide rail. The engagement of the grooves with the anti-detachment blocks precisely limits the tray's extension range, preventing it from completely detaching from the guide rail and causing material spillage. This is particularly beneficial for lightweight isoleucine derivative powders or granules, significantly reducing the risk of raw material loss during the feeding process. Simultaneously, the pulleys embedded in the inner wall of the sliding guide rail reduce the lower limit of frictional resistance during tray movement. When the inner wall of the clamping fixture separates from the side wall of the tray, the tray can be quickly pushed out, facilitating the feeding operation and further improving the overall operational efficiency. It also facilitates subsequent disassembly and replacement of the tray.

[0016] The various components of this equipment work together to perfectly meet the stringent requirements of isoleucine derivatives for the drying environment: springs and sliding guides solve the problem of limited feeding space, clamping and fixing components ensure that the tray remains stable during drying, and anti-detachment components and pulleys ensure safe and smooth operation. The drying process is optimized in multiple dimensions, which not only avoids oxidation, deterioration or contamination of materials due to improper operation, but also ensures the chemical stability and biological activity of isoleucine derivatives through a stable drying environment. It shows significant advantages in precision drying operations in the fields of pharmaceuticals and biochemicals. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An integrated vacuum drying and nitrogen protection chamber for isoleucine derivatives includes a vacuum nitrogen-filled drying chamber 1, which serves as the main body of the equipment, providing a sealed space for vacuum drying and nitrogen protection. It is the core carrier for drying isoleucine derivatives; its interior can be evacuated to lower the boiling point of water and filled with nitrogen to isolate oxygen. Its function is to provide a stable drying environment for easily oxidized isoleucine derivatives, preventing oxidation and deterioration due to contact with oxygen, thus ensuring drying efficiency and material activity. A sealing door 2 is hinged to one side of the front of the vacuum nitrogen-filled drying chamber 1. The vacuum nitrogen-filled drying oven 1 is sealed to maintain a vacuum or nitrogen atmosphere. The bottom of the inner wall of the vacuum nitrogen-filled drying oven 1 is fixedly connected to a bottom plate 3. The top of the bottom plate 3 is movably provided with two side plates 4, which support the sliding guide rail 5 and move relative to each other under the drive of the clamping and fixing parts 8 to clamp or release the tray 6. The opening and closing action stabilizes the tray 6 and prevents it from shifting during drying, ensuring that the material is heated and in contact with nitrogen evenly. The side walls of the side plates 4 are fixedly connected to the sliding guide rail 5. The sliding guide rail 5 is U-shaped to guide the direction of the tray 6 to be pulled out and cooperates with the pulley 10 to reduce friction. The tray 6 provides a flat surface for the material, facilitating even spreading and ensuring uniform heating and contact with nitrogen during the drying process. The tray 6 is placed between two sliding guide rails 5. Two through holes are opened on one side wall of the tray 6. A spring 7 is connected between the inner wall of the through hole and the inner wall of the vacuum nitrogen-filled drying chamber 1. When the sealing door 2 is opened, the tray 6 is slowly pushed out of the chamber by the spring 7 in conjunction with the clamping and fixing parts 8. There is no need for manual insertion into the chamber to place materials, which expands the material loading operation space and greatly reduces the risk of material spillage. Clamping and fixing parts 8 are provided between the two side plates 4 and the bottom plate 3. Anti-detachment parts 9 are provided on the sliding guide rails 5. Multiple pulleys 10 are embedded at the bottom of the inner wall of the sliding guide rails 5.

[0022] Preferably, the clamping and fixing component 8 includes an internal groove 81 formed inside the base plate 3. Sliding holes 82 are formed on both sides of the top of the internal groove 81, allowing the slider 83 to slide and restricting its direction of movement. The inner wall of the sliding hole 82 is slidably connected to the slider 83, transmitting power from the threaded rod 85 to move the side plate 4, achieving synchronous opening and closing of the side plate 4, ensuring uniform clamping of the support plate 6. The inner cavity of the internal groove 81 is connected to the inner cavity of the sliding hole 82. The top of the slider 83 is fixedly connected to the side plate 4 on the same side. A drive unit 84 is installed in the middle of the inner wall of the internal groove 81, providing power to drive the threaded rods 85 on both sides to rotate. Threaded rods 85 are symmetrically distributed on the two output shafts of the drive unit 84. The drive unit 84 is specifically a dual-axis motor. One end of the threaded rod 85 is rotatably connected to the inner wall of the internal groove 81, and the two threaded rods 85 are threadedly connected to the two sliders 83 respectively.

[0023] Preferably, the anti-detachment component 9 includes a through hole 91 opened at the front end of the sliding guide rail 5, a protrusion 92 slidably connected to the inner wall of the through hole 91, the protrusion 92 being fixedly connected to the support plate 6, an anti-detachment block 94 being provided on one side of the sliding guide rail 5 to prevent the support plate 6 from completely detaching from the sliding guide rail 5, thus playing the role of anti-detachment, a groove 93 being opened on one side of the inner wall of the through hole 91, one end of the anti-detachment block 94 slidingly penetrating the surface of the sliding guide rail 5 and engaging with the inner cavity of the groove 93.

[0024] The operation of the integrated vacuum drying and nitrogen protection chamber for isoleucine derivatives provided by this utility model is as follows: When feeding is required, the sealing door 2 is opened, and the spring 7 causes the tray 6 to move outward along the sliding guide rail 5, so that part of the tray 6 moves out of the vacuum nitrogen-filled drying chamber 1. At this time, the protrusion 92 on the tray 6 in the anti-detachment component 9 slides in the through hole 91 of the sliding guide rail 5. The anti-detachment block 94 cooperates with the groove 93 to limit the maximum push-out distance of the tray 6, preventing it from completely detaching from the guide rail. After the operator places the tray containing isoleucine derivative powder or granules on the tray 6, the tray 6 is manually pushed back into the vacuum nitrogen-filled drying chamber 1 to reset. After completion, the drive unit 84 drives two symmetrically distributed threads. Rotating rod 85 drives slider 83 to slide within sliding hole 82, thereby causing the two side plates 4 to move relative to each other along bottom plate 3, so that sliding guide rail 5 clamps tray 6 for fixation. During drying, vacuum nitrogen-filled drying chamber 1 is evacuated and filled with nitrogen. Under the action of clamping and fixing parts 8, tray 6 remains stable, ensuring that the material is heated and in contact with nitrogen evenly, ultimately achieving efficient drying of isoleucine derivatives in a safe and stable environment. When unloading, the operator opens the sealing door 2, and then the drive unit 84 drives the two threaded rods 85 to rotate, causing the two side plates to move a short distance in opposite directions, reducing the clamping force on tray 6, allowing tray 6 to slowly move the material from inside vacuum nitrogen-filled drying chamber 1 to the outside, thus completing the unloading operation.
