Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology, and in particular relates to an automatic feeding filter membrane filtration experimental device. Background Technology

[0002] Vacuum membrane filtration devices, as a filtration technology based on the principle of vacuum negative pressure, have been widely used in laboratories, industrial production, and environmental protection. Their working principle involves generating negative pressure using a vacuum pump or compressor, thereby removing air from the liquid. When the liquid flows through the filtration device, solid impurities and microorganisms are effectively intercepted by the microporous membrane, while the pure liquid passes smoothly through the filtration device and is extracted by the air extraction device, ultimately achieving liquid purification.

[0003] However, in the current laboratory environment, the operation of vacuum membrane filtration devices still has many shortcomings. Specifically, laboratory personnel must manually pick up the filter membrane with tweezers and place it above the filter core, and then clamp the containers above and below the filter membrane. This operation is not only complex and tedious, but also requires a high degree of precision and patience. The slightest carelessness may lead to misalignment or damage to the filter membrane, thereby affecting the filtration effect.

[0004] Furthermore, current vacuum membrane filtration devices require frequent cleaning and maintenance during use. Because impurities and microorganisms easily accumulate in the filtration system after prolonged use, regular cleaning and disinfection are essential to ensure filtration efficiency and device safety. However, this process is not only time-consuming and labor-intensive but may also pose a potential threat to the health of laboratory personnel.

[0005] More seriously, current vacuum membrane filtration devices also pose certain safety hazards during use. Because the liquid level in the collection bottle needs to be constantly monitored to prevent overflow or suction into the vacuum pump, which could damage the equipment or cause experimental failure, personnel must remain highly vigilant at all times. However, due to potential interference factors during the experiment, it is difficult for personnel to maintain complete concentration at all times, thus increasing the risk of experimental failure and equipment damage.

[0041] 1. This utility model achieves automatic filter membrane feeding through an innovative design of the filter membrane carrier and filter membrane adsorption assembly. This improvement not only greatly enhances operational efficiency and reduces manual operation steps, but also ensures a fast and accurate filter membrane replacement process, facilitating smooth continuous production operations and enabling efficient processing of large volumes of liquid, making it suitable for large-scale production environments.

[0042] Throughout the filtration process, from membrane installation to completion, this invention constructs a closed and automated filtration system through integrated sealing base, liquid inlet assembly, and vacuum filtration assembly. This design completely avoids direct contact between operators and the liquid to be filtered or media that may contain hazardous substances, effectively reducing occupational exposure risks and ensuring the safety and health of workers.

[0043] Automated operations reduce human intervention, thereby lowering the risk of environmental pollution caused by improper operation. At the same time, closed-loop filtration systems help collect and treat filtration waste, contributing to a cleaner production environment and meeting the requirements of modern industry for environmental protection and sustainable development.

[0044] 2. By designing a filter membrane carrier that includes a rotating frame and multiple storage cylinders, this invention achieves effective classification and storage of different types of filter membranes. This innovative design allows users to quickly and accurately switch between required filter membranes according to specific filtration needs or formulations, greatly improving the applicability and operational flexibility of the equipment. It can easily handle diverse filtration tasks, whether in scientific research experiments or industrial production.

[0045] The clever design of the filter membrane fixture separates each filter membrane, effectively preventing reduced filtration efficiency and potential clogging problems caused by multiple filter membranes working simultaneously. This design ensures that each filter membrane can independently perform its optimal filtration function, thereby improving the overall filtration effect and accuracy.

[0046] Placing different types of filter membranes in separate storage containers not only facilitates management and identification but also fundamentally avoids operational errors caused by membrane confusion. This feature is particularly important for applications that require strict adherence to specific filtration sequences or conditions, ensuring that every filtration operation is performed accurately and reducing the risks and costs associated with human error.

[0047] The rotating frame design makes changing filter membranes simple and quick, eliminating the need for complex disassembly and reinstallation. This design simplifies the operation process, reduces operation time, and thus improves overall work efficiency. This advantage is particularly evident in applications requiring frequent filter membrane changes, allowing for switching at any time according to the formulation.

[0048] 3. By designing a first suction cup and a second suction cup for adsorbing new filter membranes on the filter membrane fixture and used filter membranes on the sand core holder, respectively, this invention achieves strict separation of filter membranes during replacement. This innovative design effectively avoids direct contact between new and old filter membranes, thereby preventing potential cross-contamination problems and ensuring the purity and reliability of the filtration process.

[0049] After use, the filter membrane is automatically disposed of in the filter membrane waste bin via a second suction cup. This automated process significantly reduces the need for manual handling of used filter membranes. This design not only improves operational efficiency, but more importantly, it effectively prevents harmful substances from causing harm to personnel through direct contact during manual operation, ensuring the safety and health of operators.

[0050] By using a suction cup to automatically adsorb and discard the filter membrane, this invention simplifies the filter membrane replacement process, reducing unnecessary steps and time. This optimization not only improves work efficiency but also makes the entire filtration process smoother and more efficient.

[0051] Automated filter membrane treatment systems help reduce environmental pollution from waste filter membranes. By centrally collecting and processing used filter membranes, this invention promotes the rational use of resources and proper management of waste, meeting the requirements of modern industry for environmental protection and sustainable development.

[0063] The filter membrane carrier includes a manual feeding slide rail 1, a base 2, a rotating frame 3, and a rotating drive assembly 4. The base 2 is mounted on the manual feeding slide rail 1, the rotating frame 3 is rotatably connected to the base 2, and the rotating drive assembly 4 is mounted on the base 2 and driven by the rotating frame 3. The rotating drive assembly 4 drives the rotating frame 3 to rotate. The rotating frame 3 has several storage cylinders 5. In this embodiment, four storage cylinders 5 are provided. The top of each storage cylinder 5 is open, and several filter membrane fixtures 6 are stored sequentially from bottom to top inside each storage cylinder 5. Each filter membrane fixture 6 has a filter membrane on it. The filter membrane fixtures are made of polytetrafluoroethylene, a special material that is corrosion-resistant and does not chemically react with other materials. Each storage cylinder 5 is used to store different types of filter membranes. Rotation of the rotating frame 3 can drive one of the corresponding storage cylinders 5 to rotate to the feeding position.

[0064] It also includes a top material assembly, which holds the bottom filter membrane fixture 6 in place and moves all the filter membrane fixtures 6 upwards as a whole, so that the top filter membrane fixture 6 moves to the adsorption position. The filter membrane adsorption assembly is used to adsorb the filter membrane on the filter membrane fixture 6 in the adsorption position and transfer the filter membrane to the liquid inlet of the sand core holder 26.

[0065] Specifically, the top-loading assembly includes a top-loading component 7 and a top-loading linear drive assembly 8. The top-loading linear drive assembly 8 is mounted on the first frame 18, and the top-loading component 7 is mounted on the top-loading linear drive assembly 8.

The bottom and side walls of the storage cylinder 5 are provided with clearance notches 9 for accommodating the top-loading component 7, and the top-loading component 7 can move up and down within the clearance notches 9. In this embodiment, the top-loading linear drive assembly 8 is a linear module.

[0066] Furthermore, a tooling sensor 10 is provided on the first frame 18 to sense whether the filter membrane tooling 6 has moved to the adsorption position.

[0067] Furthermore, a tooling rejection assembly is included for rejecting the filter membrane tooling 6 that has been adsorbed and is in the adsorption position. Specifically, the tooling rejection assembly includes a rejection ring 11 and a rejection linear drive assembly, with the rejection ring 11 disposed on the rejection linear drive assembly. The rejection ring 11 is located at the top of the storage cylinder 5, and the filter membrane tooling 6 in the adsorption position is disposed within the rejection ring 11. The rejection linear drive assembly drives the rejection ring 11 to move, and the rejection ring 11 removes the filter membrane tooling 6 from the adsorption position.

[0068] The rejection linear drive assembly includes a rejection linear slide rail 12, a connecting seat 13, a drive motor 14, an eccentric block 15, and a connecting rod 16. The rejection linear slide rail 12 is mounted on a first frame 18, the connecting seat 13 is mounted on the rejection linear slide rail 12, and the rejection ring 11 is connected to the connecting seat 13. The drive motor 14 is mounted on the first frame 18, the eccentric block 15 is connected to the output shaft of the drive motor 14, and the two ends of the connecting rod 16 are hinged to the connecting seat 13 and the eccentric block 15, respectively. During operation, the drive motor 14 drives the eccentric block 15 to rotate eccentrically. The eccentric block 15 drives the connecting seat 13 to slide on the rejection linear slide rail 12 via the connecting rod 16, and the sliding of the connecting seat 13 drives the rejection ring 11 to move.

[0069] Furthermore, a tooling guide slide seat 17 is provided on one side of the filter membrane carrier, and the tooling guide slide seat 17 is provided with a downwardly angled guide groove. After the rejection ring 11 removes the filter membrane tooling 6 from the adsorption position, the filter membrane tooling 6 falls on the tooling guide slide seat 17 and slides into the predetermined position along the guide groove.

[0070] After the filter membrane fixture 6 is removed, the removal ring 11 is reset, and the top material 7 moves the next filter membrane fixture 6 upward into the removal ring 11.

[0071] The assembly includes a second frame 19, with a core holder 26 mounted on it. The filter membrane adsorption assembly includes a first suction cup 24, a second suction cup 25, an adsorption linear drive assembly 20, and a pressing drive assembly 21. The adsorption linear drive assembly 20 is mounted on the second frame 19, and the pressing drive assembly 21 is mounted on the adsorption linear drive assembly 20. The pressing drive assembly 21 has a mounting base 22, and a sealing seat 23, the first suction cup 24, and the second suction cup 25 are all mounted on the mounting base 22. The first suction cup 24 is used to adsorb new filter membranes on the filter membrane fixture 6, and the second suction cup 25 is used to adsorb used filter membranes on the core holder 26. In this embodiment, the adsorption linear drive assembly 20 is a lead screw linear module, and the pressing drive assembly 21 is an electric slide table.

[0072] The first suction cup 24 adsorbs new filter membranes onto the filter membrane fixture 6 by adsorbing the linear drive assembly 20 and the pressing drive assembly 21, while the second suction cup 25 adsorbs used filter membranes onto the sand core seat 26 by adsorbing the linear drive assembly 20 and the pressing drive assembly 21.

[0073] Furthermore, a first filter membrane sensor 30 and a second filter membrane sensor 31 are provided on the mounting base 22, which are used to detect whether there is a filter membrane on the first suction cup 24 and the second suction cup 25, respectively.

[0074] Furthermore, including the filter membrane waste bin 28, the second suction cup 25 throws the filter membrane into the filter membrane waste bin 28 by adsorption linear drive assembly 20.

[0075] The sealing seat 23 is hollow inside. The sealing seat 23 is positioned opposite the liquid inlet of the sand core seat 26, with one end of the sealing seat 23 open. The pressing drive assembly 21 is used to drive the sealing seat 23 to press and seal against the liquid inlet of the sand core seat 26. Simultaneously, the sealing seat 23 presses against the filter membrane and communicates with the interior of the sand core seat 26. The liquid inlet assembly communicates with the interior of the sealing seat 23 and is used to deliver the liquid to be filtered into the sealing seat 23. The vacuum filtration assembly communicates with the interior of the sand core seat 26 and is used to create a vacuum inside the sand core seat 26. The liquid to be filtered enters the sand core seat 26 after being filtered through the filter membrane by vacuum force. In this embodiment, the liquid inlet assembly includes a liquid inlet pipe 29.

[0076] The sand core holder 26 is equipped with a liquid level sensor, eliminating the need for manual observation of the liquid level and preventing liquid overflow or other accidents. The bottom of the sand core holder 26 has a liquid outlet 27 for discharging the filtered liquid.

[0077] The working process of this utility model will be further explained below:

[0078] First, different types of filter membranes, along with their filter membrane fixtures 6, are manually placed into different types of storage cylinders 5. According to the formula requirements, the storage cylinder 5 containing the corresponding type of filter membrane is selected and rotated to the loading position. Then, the top material component 7 lifts all the filter membrane fixtures 6, so that the topmost filter membrane fixture 6 enters the rejection ring 11.

[0079] When the tooling sensor 10 detects that the filter membrane tooling 6 has entered the rejection ring 11, the first suction cup 24 adsorbs the new filter membrane on the filter membrane tooling 6 by adsorbing the linear drive assembly 20 and the pressing drive assembly 21, and transfers it to the liquid inlet of the sand core seat 26.

[0080] Next, the clamping drive assembly 21 drives the sealing seat 23 to press and seal against the liquid inlet of the sand core seat 26. The liquid inlet pipe 29 delivers the liquid to be filtered into the sealing seat 23. The vacuum filtration assembly is activated, and the liquid to be filtered passes through the filter membrane under vacuum and enters the sand core seat 26. The process stops when the liquid level sensor on the sand core seat 26 detects the discharge. The filtered membrane is then automatically adsorbed and discarded into the filter membrane waste box 28 by the second suction cup 25.

[0081] At the same time, after the removal ring 11 removes the filter membrane fixture 6 that has been sucked up from the adsorption position, the filter membrane fixture 6 falls on the fixture guide sliding seat 17 and slides into the fixture collection box along the guide groove.

[0082] This invention achieves automatic filter membrane feeding through an innovative design of the filter membrane carrier and filter membrane adsorption assembly. This improvement not only greatly enhances operational efficiency and reduces manual operation steps, but also ensures a fast and accurate filter membrane replacement process, facilitating smooth continuous production operations and enabling efficient processing of large volumes of liquid, making it suitable for large-scale production environments.

[0083] Throughout the filtration process, from membrane installation to completion, this invention constructs a closed and automated filtration system through the integrated sealing seat 23, liquid inlet assembly, and vacuum filtration assembly. This design completely avoids direct contact between operators and the liquid to be filtered or media that may contain hazardous substances, effectively reducing occupational exposure risks and ensuring the safety and health of workers.

[0084] Automated operations reduce human intervention, thereby lowering the risk of environmental pollution caused by improper operation. At the same time, closed-loop filtration systems help collect and treat filtration waste, contributing to a cleaner production environment and meeting the requirements of modern industry for environmental protection and sustainable development.

[0085] By designing a filter membrane carrier comprising a rotating frame 3 and multiple storage cylinders 5, this invention achieves effective classification and storage of different types of filter membranes. This innovative design allows users to quickly and accurately switch between required filter membranes according to specific filtration needs or formulations, greatly improving the applicability and operational flexibility of the equipment. It can easily handle diverse filtration tasks, whether in scientific research experiments or industrial production.

This design ensures that each filter membrane can independently perform its optimal filtration function, thereby improving the overall filtration effect and accuracy.

[0087] By placing different types of filter membranes in separate storage containers 5, not only is management and identification easier, but operational errors caused by filter membrane confusion are also fundamentally avoided. This feature is particularly important for applications that require strict adherence to specific filtration sequences or conditions, ensuring that every filtration operation is performed accurately and reducing the risks and costs associated with human error.

[0088] The rotating frame 3 design makes membrane switching simple and quick, eliminating the need for complex disassembly and reinstallation. This design simplifies the operation process, reduces operation time, and thus improves overall work efficiency. This advantage is particularly evident in applications requiring frequent membrane replacement, allowing for switching at any time according to the formulation.

[0089] By designing the first suction cup 24 and the second suction cup 25 to respectively adsorb the new filter membrane on the filter membrane fixture 6 and the used filter membrane on the sand core seat 26, this invention achieves strict separation of the filter membrane during the replacement process. This innovative design effectively avoids direct contact between the new and old filter membranes, thereby preventing potential cross-contamination problems and ensuring the purity and reliability of the filtration process.

[0090] After use, the filter membrane is automatically disposed of into the filter membrane waste bin 28 via the second suction cup 25. This automated process significantly reduces the need for manual handling of used filter membranes. This design not only improves operational efficiency, but more importantly, it effectively prevents harmful substances from causing harm to personnel through direct contact during manual operation, thus ensuring the safety and health of operators.

By centrally collecting and processing used filter membranes, this invention promotes the rational use of resources and proper management of waste, meeting the requirements of modern industry for environmental protection and sustainable development. The embodiments of this invention have been described in detail above with reference to the accompanying drawings; however, this invention is not limited to the described embodiments. Even if various modifications are made to this invention, if these modifications fall within the scope of the claims of this invention and their equivalents, they shall still fall within the protection scope of this invention.
