Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical excipient storage technology, specifically a dry and sealed storage bin for pharmaceutical excipients. Background Technology

[0002] In the pharmaceutical manufacturing process, the storage quality of pharmaceutical excipients directly affects the safety and stability of drugs. Pharmaceutical excipients are often highly hygroscopic and easily contaminated. If the storage environment has excessive humidity or is not properly sealed, they are prone to clumping, deliquescence, mold growth, or the introduction of foreign matter, leading to changes in the physicochemical properties of the excipients and consequently affecting the formulation's formability, dissolution rate, and efficacy. Therefore, storage equipment with both drying and sealing functions is a crucial aspect of pharmaceutical excipient quality management.

[0003] Existing pharmaceutical excipient storage silos mostly use fixed internal drying components. Replacing the desiccant requires fully opening the silo door, allowing external moisture and dust to directly intrude, disrupting the internal drying environment. This process is cumbersome and time-consuming. Furthermore, switching between drying and ventilation functions is difficult, resulting in low flexibility and negatively impacting the storage effectiveness of pharmaceutical excipients. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a dry and sealed storage chamber for pharmaceutical excipients, which solves the problem mentioned in the background art that the drying components of existing pharmaceutical excipient storage chambers are mostly fixed inside the chamber, and the chamber door must be fully opened when the desiccant is replaced, which leads to the direct intrusion of external moisture and dust, destroying the internal drying environment, and the operation is cumbersome and time-consuming.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical excipient drying and sealing storage chamber, comprising a chamber body and a storage rack. The top of the chamber body is provided with two slots, and a drying frame is inserted into the inner side of each of the two slots. The top of the drying frame is provided with an opening and a movable plate is detachably connected by bolts. The left and right drying frames are fixedly connected by a lifting frame. Two partitions are fixedly connected to the inner side of the chamber body. Three ventilation slots are opened on the surface of the partitions, and a fan is installed inside the ventilation slots.

[0006] In this technical solution, a pluggable drying frame is installed at the top of the chamber, which, together with a lifting frame, allows for complete removal and replacement of the desiccant without opening the chamber, preventing external environmental interference with the internal drying process. While carrying the desiccant, the drying frame continuously absorbs moisture from the chamber. When ventilation is needed, the drying frame is removed and the fan is activated, forming an exhaust channel through the ventilation slots and vents to quickly regulate the humidity inside the chamber. Compared to traditional fixed drying structures, this solution allows for flexible switching between drying and ventilation.

[0007] Preferably, the left and right side walls of the chamber are provided with ventilation openings for carrying filters, and the opening of the drying frame faces the center of the chamber and is fixedly connected with an intercepting net.

[0008] Preferably, the sidewall surfaces of the left and right partitions are provided with three sliding grooves, the left and right ends of the storage rack are respectively located inside the sliding grooves on the left and right sides and are slidably connected to the sliding grooves, and the surface of the storage rack is set in an open shape and fixedly connected with a support net.

[0009] Preferably, constraint frames are fixedly connected to both sides of the top of the hopper, and baffles are slidably connected to the inner side of the constraint frames.

[0010] Preferably, a gear is rotatably connected to the center of the top of the chamber, the gear meshes with the convex teeth on the surfaces of the front and rear toothed plates, and the front and rear toothed plates are respectively fixedly connected to the baffles on the left and right sides.

[0011] Preferably, a fixing block with a round hole is fixedly connected to the front and rear edges of the top of the drying frame, and an insert block is fixedly connected to the front and rear edges of the side surface of the baffle facing the drying frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a removable drying frame at the top of the chamber, which, together with a lifting frame, allows for complete removal and replacement of the desiccant without opening the chamber, preventing external environmental interference with the internal drying process. When carrying desiccant, the drying frame continuously absorbs moisture from the chamber. When ventilation is needed, the drying frame is removed and the fan is activated. The ventilation channels and vents form an exhaust channel, quickly regulating the humidity inside the chamber. Compared to traditional fixed drying structures, this design allows for flexible switching between drying and ventilation, improving operational efficiency.

[0014] 2. This utility model controls the lateral movement of the baffle through the linkage of gears and toothed plates. When the drying frame is pulled out, the baffle automatically closes the slot to prevent external dust and moisture from entering. After the drying frame is inserted, the insert on the baffle is precisely embedded into the round hole of the fixing block of the drying frame, forming a mechanical lock and enhancing the stability of the drying frame installation.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0023] A dry and sealed storage silo for pharmaceutical excipients, see [link to silo]. Figures 1 to 5 The system includes a chamber 1 and a storage rack 4. The top of the chamber 1 has two slots 102, and a drying frame 2 is inserted into the inner side of each slot 102. The top of the drying frame 2 has an opening and a movable plate 203 is detachably connected by bolts. The movable plate 203 is detachable by bolts, making it easy to open the drying frame 2 to add or replace the desiccant. The left and right drying frames 2 are fixedly connected by a lifting frame 204. The opening of the drying frame 2 faces the center of the chamber 1 and is fixedly connected to an intercepting net 201. Silica gel desiccant or molecular sieves can be placed inside the drying frame 2. The intercepting net 201 at the opening prevents desiccant particles from leaking into the chamber 1, while allowing moisture inside the chamber to be absorbed through the mesh. The lifting frame 204 connects the left and right drying frames 2, allowing them to be inserted and removed simultaneously for convenience and speed.

[0024] Specifically, such as Figure 2 and Figure 5 As shown, two partitions 3 are fixedly connected to the inner side of the compartment 1. Three ventilation slots 302 are opened on the surface of the partitions 3. A fan 303 is installed on the inner side of the ventilation slots 302. Ventilation ports 101 carrying filters are opened on the left and right side walls of the compartment 1. When the humidity in the compartment exceeds the standard and ventilation is required, the drying frame 2 is pulled out and the fan 303 is started. The fan 303 rotates to generate negative pressure, which allows outside air to enter through the ventilation port 101. It forms an exhaust channel between the partitions 3 through the ventilation slots 302. When it flows through the storage rack 4, it carries away the moisture and finally exits from the ventilation port 101 on the other side.

[0025] In the above technical solution, the drying frame 2 and the fan 303 work together to achieve flexible switching between drying and ventilation, improving operational efficiency. It should be noted that when the drying frame 2 is inserted, it will completely block the ventilation opening 101, thereby achieving a sealing effect. The outer edge of the drying frame 2 is provided with a sealing strip, which can fill the gaps at the edges of the slot 102 and the ventilation opening 101 to ensure a seal.

[0026] Furthermore, such as Figure 5 As shown, constraint frames 5 are fixedly connected to both sides of the top of the chamber 1. Baffles 6 are slidably connected to the inner side of the constraint frames 5. A gear 7 is rotatably connected to the center of the top of the chamber 1. The gear 7 meshes with the protruding teeth on the surfaces of the toothed plates 602 on the front and rear sides, and the toothed plates 602 on the front and rear sides are fixedly connected to the baffles 6 on the left and right sides, respectively. When the gear 7 is rotated, the meshing transmission of the toothed plates 602 drives the left and right baffles 6 to slide in opposite directions within the constraint frames 5, thereby sealing the slot 102. A sealing gasket is also provided at the bottom of the baffles 6 to ensure the sealing of the slot 102. The constraint frames 5 ensure that the baffles 6 slide smoothly and avoid deviation, significantly reducing the risk of external moisture intrusion. It should be noted that the rotation of the gear 7 has a certain damping effect, thereby playing a partial limiting role and preventing the baffles 6 from sliding back and forth due to its free rotation, thus improving the stability of the baffles 6 during the sealing process.

[0027] Specifically, such as Figure 3 and Figure 5 As shown, a fixing block 202 with a round hole is fixedly connected to the front and rear edges of the top of the drying frame 2. An insert block 601 is fixedly connected to the front and rear edges of the side of the baffle 6 facing the drying frame 2. When the drying frame 2 is inserted into the slot 102, the gear 7 is rotated to reset the baffle 6. The insert block 601 on the surface of the baffle 6 is precisely inserted into the round hole of the fixing block 202 (clearance fit) to form a lock. The fit between the insert block 601 and the round hole can offset the displacement of the drying frame 2 caused by vibration, and enhance the stability of the installation of the drying frame 2.

[0028] It is worth noting that, such as Figure 1 and Figure 4 As shown, three grooves 301 are provided on the side wall surfaces of the left and right partitions 3. The left and right ends of the storage rack 4 are located inside the grooves 301 on the left and right sides respectively and are slidably connected to the grooves 301. The surface of the storage rack 4 is set in an open shape and a support net 401 is fixedly connected to it. The storage rack 4 achieves a pull-out design through the grooves 301, which makes it easy to place pharmaceutical excipients on the support net 401. The hollow structure of the support net 401 allows airflow to penetrate the excipient layer, ensuring that each layer of material can be dried evenly, avoiding the bottom material from deliquescence due to accumulation. Furthermore, after the door of the compartment 1 is completely closed, it can just hold the storage rack 4, thereby ensuring the stability of the storage rack 4.

[0029] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
