Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a high-efficiency chemical reagent and auxiliary agent extraction device. Background Technology

[0002] In chemical industrial production and laboratory research, the extraction of chemical reagents or auxiliaries is a crucial step in obtaining high-purity target products. Typically, the target product forms a mixture with reaction solvents, byproducts, or impurities, requiring purification through extraction, separation, or other methods. Centrifugation technology, due to its high efficiency and speed, is widely used in liquid-liquid extraction or solid-liquid separation scenarios. It utilizes the powerful centrifugal force generated by high-speed rotation to accelerate the stratification and separation of components with different densities.

[0003] To further improve extraction efficiency and product purity, a single separation unit often cannot meet high standards. Therefore, in practical applications, multiple centrifugal separation units are often connected in series through pipelines to form a multi-stage extraction system, enabling the material to undergo continuous and in-depth processing within the system.

[0004] Currently, the pipe connections between separation units generally use traditional flange or threaded connections. These connections require multiple tools, such as wrenches, for installation and disassembly, making the process cumbersome and time-consuming. This is especially problematic in situations requiring frequent equipment maintenance, pipeline cleaning, or process changes, severely impacting overall work efficiency.

[0005] The drawbacks of this traditional connection method are particularly pronounced when handling volatile, corrosive, toxic, or expensive chemicals. Upon disassembly, the unavoidable presence of liquid residue within the equipment and pipes causes immediate leakage of these chemicals—a phenomenon commonly known as "running, leaking, dripping, or seeping." Such leaks not only waste expensive materials but also pose a direct threat to the health of on-site personnel and pollute the surrounding environment, creating significant safety hazards. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a high-efficiency chemical reagent and auxiliary agent extraction device, which aims to improve the existing high-efficiency chemical reagent and auxiliary agent extraction devices. The pipe connections are usually fixed by flanges or threads, which makes the disassembly and assembly process cumbersome and time-consuming. Moreover, chemical reagent leakage is likely to occur at the moment of disassembling the connecting pipes, posing a safety hazard.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency chemical reagent and auxiliary agent extraction device, comprising: a shock-absorbing base, a support, a driving mechanism, a separation mechanism, and a connecting pipe; as well as a connecting mechanism and a self-sealing mechanism.

[0008] The connecting mechanism includes a connecting sleeve fixed to the outer wall of the housing of the separating mechanism. The connecting sleeve is provided with a wedge-shaped card for engaging the connecting pipe. A disassembly ring is movably provided on the connecting sleeve. The self-sealing mechanism is provided at the connection between the connecting sleeve and the housing. It includes a housing with a slot. A pressure rod is axially slidably provided in the housing. A sealing ring is provided on the outer wall of the pressure rod. The pressure rod is driven by a spring. A top block is provided at the insertion end of the connecting pipe.

[0009] When the connecting pipe is installed with the connecting sleeve, the top block abuts against and pushes the pressure rod to displace, causing the sealing ring to misalign with the slot to form a passage; when the connecting pipe is disassembled, the pressure rod is reset under the action of the spring, causing the sealing ring to cover the slot to form a seal; when the disassembly ring is under force, it can push the wedge-shaped card to release the connection of the connecting pipe.

[0010] Preferably, the disassembly ring is sleeved on the outer periphery of the connecting sleeve.

[0011] Preferably, the connecting mechanism further includes a limiting ring disposed on the connecting sleeve, the limiting ring being used to limit the axial sliding range of the disassembly ring.

[0012] Preferably, the self-sealing mechanism further includes a limiting plate fixedly connected to one end of the pressure rod, and one end of the spring abuts against the limiting plate.

[0013] Preferably, the other end of the spring abuts against the inner wall of the housing.

[0014] Preferably, the driving mechanism includes a motor, and the output end of the motor is connected to the worm gear separating barrel in the separating mechanism.

[0015] Preferably, both the driving mechanism and the separating mechanism are mounted and fixed on the bracket.

[0016] Preferably, it includes at least two of the separation mechanisms, and multiple separation mechanisms are connected in series through the connecting pipe, the connecting mechanism and the self-sealing mechanism.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, a quick plug-in connection between the connecting pipe and the main body of the equipment is achieved by setting a connecting mechanism. During installation, simply push it in to automatically lock it in place, and during disassembly, press the disassembly ring to unlock it. The entire process requires no tools, making the operation extremely simple and quick, and significantly improving the efficiency of equipment installation, maintenance, and process switching.

[0019] 2. In this utility model, the self-sealing mechanism automatically closes the internal self-sealing valve instantly under the action of the spring when the connecting pipe is disassembled, effectively preventing the leakage of chemical reagents, greatly improving the safety of operation, avoiding harm to personnel and the environment, and reducing the loss of expensive materials, thus ensuring high reliability.

[0028] 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.

[0029] Reference Figures 1-6 The present invention provides an embodiment of a high-efficiency chemical reagent and auxiliary agent extraction device, which aims to solve the problems of inconvenient pipe connection and disassembly and easy leakage in the prior art chemical reagent extraction device.

[0030] This high-efficiency chemical reagent and auxiliary agent extraction device includes a shock-absorbing base 1, a support 2, a drive mechanism 3, a separation mechanism 4, and a connecting pipe 5. The shock-absorbing base 1 is located at the bottom of the device and is used to absorb and reduce the vibration generated during the operation of the equipment. The support 2 is fixedly connected to the upper surface of the shock-absorbing base 1. The drive mechanism 3 and the separation mechanism 4 are both mounted and fixed on the support 2. The drive mechanism 3 is used to provide rotational power to the separation mechanism 4, and the drive mechanism 3 drives the separation mechanism 4 to rotate at high speed. The connecting pipe 5 is used to transport chemicals between multiple separation mechanisms 4.

[0031] The drive mechanism 3 includes a motor 301, the output end of which is connected to the separation mechanism 4 for transmission; the separation mechanism 4 includes a housing 401 and a worm gear separation barrel 402 rotatably disposed inside the housing 401; the motor 301 provides stable and high-speed rotational power to the worm gear separation barrel 402.

[0032] This embodiment also includes a connecting mechanism 6 and a self-sealing mechanism 8. The connecting mechanism 6 includes a connecting sleeve 604 fixedly connected to the outer wall of the housing 401; an annular disassembly ring 602 is slidably sleeved on the outer periphery of the connecting sleeve 604; a limiting ring 603 is also fixedly provided on the connecting sleeve 604, the limiting ring 603 is used to limit the axial sliding range of the disassembly ring 602, and can prevent the disassembly ring 602 from falling off the connecting sleeve 604; a wedge-shaped card 601 is movably disposed in the internal receiving cavity of the connecting sleeve 604, the wedge-shaped card 601 is used to snap and fix the inserted connecting pipe 5.

[0033] The self-sealing mechanism 8 is located at the fluid outlet connection between the connecting sleeve 604 and the housing 401. The self-sealing mechanism 8 includes a housing 806, which has a fluid channel inside and a slot 801 on the side wall of the channel. A pressure rod 803 is axially slidably arranged inside the housing 806, and a sealing ring 804 is circumferentially fixed on the outer wall of the pressure rod 803. A limiting plate 802 is fixedly connected to one end of the pressure rod 803 away from the connecting pipe 5. A spring 805 is located between the limiting plate 802 and the inner end wall of the housing 806. One end of the spring 805 abuts against the limiting plate 802, and the other end abuts against the inner wall of the housing 806, continuously providing a restoring force to the pressure rod 803 pointing to the sealing position.

[0034] When the connecting pipe 5 is connected to the separation mechanism 4, the insertion end of the connecting pipe 5 extends into the connecting sleeve 604. At this time, the outer wall of the connecting pipe 5 is automatically clamped by the wedge-shaped card 601. At the same time, the top block 7 provided at the insertion end of the connecting pipe 5 abuts against and pushes the pressure rod 803, causing the pressure rod 803 to overcome the elastic force of the spring 805 and undergo axial displacement. This displacement causes the sealing ring 804 on the outer wall of the pressure rod 803 to move and leave the position of the housing 806, thereby connecting the slot 801 with the internal channel of the housing 806 to form a fluid passage.

[0035] When it is necessary to disassemble the connecting pipe 5, the disassembly ring 602 is pushed axially. The disassembly ring 602 pushes the wedge-shaped card 601 to unlock and separate from the connecting pipe 5. During the process of the connecting pipe 5 being pulled out, the top block 7 separates from the pressure rod 803. Under the elastic force of the spring 805, the pressure rod 803 is pushed back to its original position through the limiting plate 802. The reset causes the sealing ring 804 to move back to the slot 801 and cover it, thereby achieving automatic sealing of the fluid outlet.

[0036] The device includes at least two identical separation mechanisms 4, and multiple separation mechanisms 4 are connected in series via connecting pipes 5, connecting mechanisms 6 and self-sealing mechanisms 8; the outlet of the previous separation mechanism 4 is connected to the inlet of the next separation mechanism 4 via connecting pipes 5, thus forming a multi-stage extraction process.

[0037] When this device is in operation, the output end of motor 301 drives the worm gear separation tank 402 inside the housing 401 to rotate at high speed. The chemicals entering the worm gear separation tank 402 are separated under the action of centrifugal force. The separated components flow out from the connecting pipe 5 on the outer wall of the housing 401 and enter the next separation mechanism 4 for further separation. Through this multi-stage separation method, the extraction quality and efficiency of chemicals are improved. The specific transmission connection between the drive mechanism 3 and the worm gear separation tank 402 is a well-known technology in the field and will not be described in detail here.

[0038] Working principle: When performing chemical extraction connection, the operator only needs to align the insertion end of the connecting pipe 5 and push it into the connecting sleeve 604 on the outer wall of the housing 401. During the insertion process, the connecting pipe 5 squeezes the wedge card 601. When it reaches the predetermined position, the wedge card 601 automatically fits inward and locks the connecting pipe 5, completing the installation and fixing. At the same time as the connecting pipe 5 is pushed in, the top block 7 at its end will abut against and push the pressure rod 803 in the self-sealing mechanism 8. The pressure rod 803 overcomes the elastic force of the spring 805 and drives the sealing ring 804 to move axially, causing the sealing ring 804 to leave and expose the slot 801 on the housing 806, thereby opening the fluid passage.

[0039] When extraction is complete or pipeline replacement is required, the operator presses the disassembly ring 602. After the disassembly ring 602 is subjected to force, it pushes into the connecting sleeve 604 and pushes the wedge-shaped card 601 to unlock the connecting pipe 5. At this time, the connecting pipe 5 can be pulled out from the connecting sleeve 604. At the moment of extraction, the top block 7 separates from the pressure rod 803, and the pushing force on the pressure rod 803 disappears. Under the action of the reset elastic force of the spring 805, the pressure rod 803 is pushed back to its original position via the limiting plate 802, which in turn causes the sealing ring 804 on its outer wall to cover and seal the slot 801 again, instantly closing the fluid passage and effectively preventing chemical leakage.

[0040] When the device performs extraction, the motor 301 in the drive mechanism 3 starts, and its output end drives the worm gear separation tank 402 in the inner shell 401 of the separation mechanism 4 to rotate at high speed. After the chemical to be extracted enters the worm gear separation tank 402, under the action of strong centrifugal force, the components with different densities are quickly separated. The separated target chemical components flow out from the outlet of the shell 401, and enter the next series separation mechanism 4 for higher precision secondary separation through the self-sealing mechanism 8 and the connecting pipe 5. Through this multi-stage series separation method, the final extraction quality and efficiency of the chemical are significantly improved.
