Description

Technical Field

[0001] This utility model relates to the field of solvent recovery technology, and in particular to a novel experimental device for recovering pharmaceutical solvents. Background Technology

[0002] In pharmaceutical research and production, solvent recovery is a routine and crucial step, directly impacting experimental costs and environmental protection. Currently, laboratory-scale solvent recovery largely relies on simple, independent recovery devices or fixed pipeline systems. The former is inefficient, unable to handle continuous operations with multiple locations and samples, and the switching between different recovery tasks is cumbersome, severely affecting experimental efficiency; the latter lacks flexibility, being difficult to adjust once built and unable to adapt to the diverse sizes and frequently changing layouts of laboratory equipment.

[0003] More importantly, conventional connection methods pose a risk of inadequate sealing, potentially leading to the volatilization of flammable and toxic solvents, posing safety hazards, and causing material loss and environmental pollution. Therefore, there is an urgent need in this field for a novel experimental device that can achieve rapid, sealed, and flexible switching, while possessing high integration and operational safety. To address this, a novel pharmaceutical solvent recovery experimental device is proposed to solve the aforementioned problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a novel experimental device for solvent recovery in pharmaceuticals, aiming to improve the problem of rapid switching between multiple workstations in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel experimental device for recovering pharmaceutical solvents includes a workbench. A protective tube is fixedly connected inside the workbench. A multi-head pump is fixedly connected to one end of the protective tube. A recovery bottle is fixedly connected to one end of the multi-head pump. Multiple flow tubes are fixedly connected to the other end of the multi-head pump. An external sleeve is fixedly connected to the outside of the protective tube. A spring is fitted on the outside of the protective tube. A fixed sleeve is slidably connected to the outside of the protective tube. A retaining ball is engaged inside the protective tube. A recovery column is rotatably connected inside the protective tube. A constraint shaft is fixedly connected to the outside of the recovery column.

As a further description of the above technical solution: The replacement assembly includes multiple recycling tubes, one end of which is fixedly connected to the outside of the recycling column. A recycling head is rotatably connected inside the recycling tube. Multiple slots are provided inside the recycling tube, and a leak-proof ring is fixedly connected inside the recycling tube. As a further description of the above technical solution: The fixed sleeve is pushed to compress the spring, thereby controlling the compression of the retaining ball by the fixed sleeve to disappear, so that the recovery column is freed from the compression of multiple retaining balls from the outside, and the recovery column is controlled to rotate; As a further description of the above technical solution: The constraint shaft rotates within the protective tube to control the rotation of the recovery column and prevent it from detaching. As a further description of the above technical solution: The flow tube is made of a relatively soft material to provide sufficient flexibility when controlling the rotation of the recovery column; As a further description of the above technical solution: Release the retaining sleeve, the spring releases its elastic force, and then pushes the retaining sleeve to re-squeeze the multiple retaining balls, thereby regaining control of the fixing of the recycling column, making it easier for the user to control the use of the required recycling end; As a further description of the above technical solution: Depending on the laboratory environment and the needs of the bottles used, slide one end of the recycling head that needs to be used into the slot in the recycling tube and rotate it to engage for easy replacement. As a further description of the above technical solution: The leak-proof ring facilitates quick connection and prevents solvent leakage. The multi-head pump starts and controls the solvent to enter the recovery bottle through the recovery pipe and the flow pipe connected to it.

[0006] This utility model has the following beneficial effects: 1. In this utility model, the device controls the locking or releasing of the central column by pushing and pulling the sleeve, enabling rapid rotation and switching between different recycling positions. After selection, the sleeve is released, and the spring force drives the locking ball to relock the column, ensuring stability. Then, the pump unit is started, and the solvent at the designated location can be safely recycled to the collection bottle. The operation is simple and the sealing is good.

[0007] 2. In this utility model, the replacement component uses a rotating locking structure to allow different sized interface heads to quickly lock onto the connecting pipe.

[0010] 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.

[0011] Reference Figures 1 to 3 This utility model provides an embodiment of a novel pharmaceutical solvent recovery experimental device, comprising a workbench 1, which is designed as the basic platform and support frame of the entire device, used to integrate and fix all other functional components. A protective tube 2 is fixedly connected inside the workbench 1, which is designed as the core support and guiding structure. A multi-head pump 3 is fixedly connected to one end of the protective tube 2, which is designed as the core power source of the device, and its function is to provide the suction required for solvent recovery. A recovery bottle 4 is fixedly connected to one end of the multi-head pump 3, which is designed as a centralized collection and storage container for the recovered solvent, and is the final storage container of the device. Multiple flow tubes 5 are fixedly connected to the other end of the multi-head pump 3, which are designed as channels for solvent flow. An external sleeve 6 is fixedly connected to the outside of the protective tube 2, which is designed to provide support for other components. A spring 7 is fitted on the outside of the protective tube 2, which is designed to provide continuous rebound force.

[0012] The outer surface of the protective tube 2 is slidably connected to a fixed sleeve 8, which is designed to switch between the locked and unlocked states of the retrieval column 10. The inner surface of the protective tube 2 is engaged with a retaining ball 9, which serves as an intermediate transmission component of the locking mechanism. The inner surface of the protective tube 2 is rotatably connected to the retrieval column 10, which is designed to enable rapid switching between different retrieval points. Pushing the fixed sleeve 8 compresses the spring 7, thereby controlling the compression of the retaining ball 9 by the fixed sleeve 8 to disappear, thus freeing the retrieval column 10 from external compression by multiple retaining balls 9, controlling the rotation of the retrieval column 10. The flow tube 5 is made of a relatively soft material. When controlling the rotation of the recycling column 10, sufficient flexibility is provided to release the fixing sleeve 8. The spring 7 releases its elastic force, thereby pushing the fixing sleeve 8 to re-press the multiple locking balls 9, thus regaining control of the fixing of the recycling column 10. This facilitates user control of the desired recycling end. The external fixed connection of the recycling column 10 is a constraint shaft 11, which is designed to ensure that its axial position is fixed. The constraint shaft 11 rotates within the protective tube 2 to control the rotation of the recycling column 10 and prevent detachment. The external fixed connection of the recycling column 10 has a replacement component that allows for easy replacement of different connection ports according to different environments. Reference Figure 1 , Figure 4 The replacement component includes multiple recovery tubes 12, which are designed as connecting bridges and fluid channels. One end of each recovery tube 12 is fixedly connected to the outside of the recovery column 10. A recovery head 13 is rotatably connected inside the recovery tube 12, which is designed as a direct functional end for quick adaptation. Multiple slots 14 are provided inside the recovery tube 12, which are designed for quick connection and locking to ensure a firm and sealed connection. Depending on the needs of the laboratory bottles used in different environments, one end of the recovery head 13 that needs to be adapted to the bottle is slid into the slot 14 inside the recovery tube 12 and rotated to engage, making replacement easy.

[0013] The inside of the recovery tube 12 is fixedly connected with a leak-proof ring 15. This design is intended to form an effective seal to prevent solvent from leaking or evaporating at the interface. The leak-proof ring 15 facilitates quick connection and prevents solvent leakage. The multi-head pump 3 starts to control the solvent to enter the recovery bottle 4 through the recovery tube 12 and its connected flow tube 5.

[0014] Working Principle: This novel pharmaceutical solvent recovery experimental device revolves around an innovative rotary dispensing structure integrated within the workbench 1. The key to this structure lies in the protective tube 2 and its internal rotatable recovery column 10. The recovery column 10 is rotatably connected to the protective tube 2 via a constraint shaft 11, ensuring stable rotation without detachment. Multiple recovery tubes 12 are radially connected to the recovery column 10, each connected to a common multi-head pump 3 via an independent flow tube 5. The outlet of the multi-head pump 3 leads to the recovery bottle 4. The ingenious aspect of the device lies in its rapid switching and locking mechanism. A spring 7 is fitted around the outside of the protective tube 2 and slidably connected to a fixed sleeve 8. In the default state, the elastic force of the spring 7 pushes the fixed sleeve 8 forward, causing it to compress multiple locking balls 9 located inside the protective tube 2. These locking balls 9, under pressure, lock the recovery column 10, preventing it from rotating, thus locking the entire system at the currently used recovery tube 12 position. When switching to a different recovery point is required, the operator simply pushes the fixed sleeve 8 along the protective tube 2, compressing the spring 7. The movement of the retaining sleeve 8 releases the pressure on the locking ball 9, causing it to loosen and unlock the recovery column 10, allowing it to rotate freely. The operator can then easily rotate the recovery column 10 to the desired angle, aligning the target recovery tube 12 with the solvent source to be recovered. After angle adjustment, the retaining sleeve 8 is released. The spring 7 immediately returns to its original shape, pushing the retaining sleeve 8 back to its original position and re-pressing the locking ball 9 inward. The locking ball 9 then firmly locks the recovery column 10 again, achieving precise and reliable relocking. Finally, the multi-head pump 3 is activated, and the solvent is safely pumped from the target location through the corresponding recovery tube 12 and flow tube 5 into the recovery bottle 4. The use of a relatively soft material in the flow tube 5 provides the necessary flexibility throughout the process, ensuring smooth and unobstructed rotation. This design offers significant advantages: it enables rapid, one-button switching between multiple recovery points, greatly improving experimental efficiency; its mechanical locking mechanism ensures a stable connection during use, effectively preventing the risk of solvent leakage; and the entire system is highly integrated and compact, keeping the workbench neat and tidy, and operation simple and intuitive.

[0015] The core function of this device's interchangeable components is to achieve rapid adaptation and sealing of the recovery head 13. Its specific working principle is as follows: When dealing with laboratory bottles of different sizes or shapes, the operator inserts the recovery head 13, which matches the current bottle opening, into the recovery tube 12. By rotating the recovery head 13, it engages with the slot 14 on the inner wall of the recovery tube 12, thus completing the mechanical connection. This rotational engagement structure ensures ease and reliability of connection. Simultaneously, the leak-proof ring 15, fixedly installed inside the recovery tube 12, immediately functions after the recovery head 13 is inserted, forming a tight seal with its outer surface, effectively preventing leakage or evaporation that may occur during solvent recovery, ensuring operational safety and solvent recovery rate. The entire process requires no tools and achieves rapid, sealed switching between different interfaces.

[0016] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
