Description

Technical Field

[0001] This utility model belongs to the field of air purification technology, specifically a modular combined air filter for cleanrooms. Background Technology

[0002] Currently, fixed integrated filters are commonly used in cleanroom air filtration systems for air purification. Due to the complex environment and high air quality requirements of cleanrooms, these filters require regular maintenance and replacement. However, traditional integrated filters are typically a single unit, requiring significant time and manpower for installation and disassembly, especially in multi-area or multi-module cleanrooms, making rapid replacement and flexible adjustment difficult. Furthermore, the purification needs of different areas may vary, and existing filters often have fixed functional modules that cannot be combined or expanded according to actual needs, resulting in low equipment utilization and increased operating costs. When replacing filters, workers often need specialized tools, making the process cumbersome and inefficient. Frequent disassembly and reassembly can also damage the equipment, further impacting overall purification effectiveness and work efficiency. Utility Model Content

[0003] This invention provides a modular, combined air filter for cleanrooms, aiming to solve the problems mentioned in the background art. The filter mainly consists of a frame assembly, multiple functional modules mounted on the frame assembly, and a quick-assembly and disassembly mechanism for connection and fixation. The frame assembly forms the main structure, and the functional modules are installed on the frame assembly via the quick-assembly and disassembly mechanism to achieve modular combination and flexible adjustment.

[0004] The frame assembly includes a main frame, guide rails installed inside the main frame, and end plates fixed to both ends of the main frame. The main frame is a rectangular structure made of lightweight, high-strength materials. Its inner walls have several parallel guide rails, the number and position of which match the installation requirements of the functional modules. The guide rails have a T-shaped cross-section and a groove at the top with embedded ball bearings to reduce friction during installation and disassembly of the functional modules. The end plates are bolted to both ends of the main frame and have through holes for securing the entire filter to the walls or ceiling of the cleanroom. The bottom of the main frame has a drainage channel for collecting and draining condensate or other liquids generated during the filtration process.

[0005] The functional modules include a primary filtration module, a high-efficiency filter module, and an activated carbon adsorption module. Each module is independently designed and replaceable. The primary filtration module is located at the front of the frame assembly, with a metal mesh cover on its outer side to intercept large particles. The metal mesh cover is secured to the outer frame of the primary filtration module with clips for easy cleaning and maintenance. The primary filtration module is filled with fiber filter media, which is fixed to the module frame by pressure strips. Elastic gaskets at both ends of the pressure strips ensure that the fiber filter media does not shift during use. The high-efficiency filter module is located behind the primary filtration module. It contains a pleated filter element with an electrostatic coating to enhance its ability to capture fine particles. The pleated filter element is secured to the frame of the high-efficiency filter module by slots with positioning pins on both sides of the slots to prevent the filter element from shifting under airflow impact. The activated carbon adsorption module is located behind the high-efficiency filtration module. It is filled with granular activated carbon, which is arranged in layers by porous partitions to improve adsorption efficiency. The surface of the porous partition has ventilation holes, the diameter of which is precisely calculated to ensure uniform airflow distribution.

[0006] The quick-release mechanism includes a slider, a locking element, and a guide rod. The slider is fixed to both sides of the functional module. The bottom of the slider has a protrusion that matches the guide rail groove; the surface of the protrusion is polished to further reduce the coefficient of friction. The locking element is located on the top of the slider, and its opening and closing state is controlled by rotating a handle. When the handle is rotated clockwise, the clamping part of the locking element tightly engages with the guide rail groove, thus fixing the functional module to the frame assembly; when the handle is rotated counterclockwise, the locking element releases, and the functional module can slide along the guide rail and be removed. The guide rod passes through the slider and the locking element, and both ends of the guide rod are fixed to the frame assembly by nuts to ensure that the slider maintains linear motion during movement.

[0007] This utility model discloses a modular, combined cleanroom air filter. Through the synergistic effect of frame components, functional modules, and a quick-assembly / disassembly mechanism, it solves the problems of cumbersome installation and disassembly, inflexible adjustment, and low equipment utilization associated with traditional filters. The frame component design allows for free combination of functional modules according to actual needs, the quick-assembly / disassembly mechanism significantly improves filter maintenance efficiency, and the independent design of functional modules enables precise matching of purification needs in different areas. Furthermore, the drainage channel at the bottom of the main frame effectively prevents condensate accumulation from affecting the filtration effect, further enhancing overall performance.

[0008] The structure of this utility model is reasonable, the connection between the components is clear and reliable, and all technical means can be realized through conventional processing technology, thus possessing good practicality and promotional value. Attached Figure Description

[0014] like Figures 1 to 3 As shown, the modular combined air filter for cleanrooms of this utility model achieves its structural design through the cooperation of a main frame 1, guide rail 2, end plate 3, drainage trough 4, primary filtration module 5, high-efficiency filtration module 6, activated carbon adsorption module 7, slider 8, locking component 9, and guide rod 10. The following detailed description, in conjunction with the accompanying drawings, explains the connection relationships, positional relationships, and mutual cooperation relationships between the components, and describes the specific operating principle and process.

[0015] The main frame 1 is a rectangular structure made of lightweight, high-strength materials. Several parallel guide rails 2 are arranged on its inner wall, the number and position of which match the installation requirements of the functional modules. The guide rails 2 have a "T"-shaped cross-section and a groove at their top, with ball bearings embedded within the groove to reduce friction during installation and disassembly of the functional modules. End plates 3 are bolted to both ends of the main frame 1. The end plates 3 have through holes for securing the entire filter to the walls or ceiling of the cleanroom. A drainage trough 4 extends along the length of the main frame 1 at its bottom, collecting and draining condensate or other liquids generated during the filtration process. A drain outlet is located at the bottom of the drainage trough 4, connected to an external drainage system via a flexible hose to ensure timely drainage of condensate.

[0016] The primary filter module 5 is located at the front end of the frame assembly, with a metal mesh cover on its outer side. The metal mesh cover is fixed to the outer frame of the primary filter module 5 by clips. The primary filter module 5 is filled with fiber filter media, which is fixed in the module frame by pressure strips. The ends of the pressure strips are equipped with elastic pads to ensure that the fiber filter media will not shift during use. Slider blocks 8 are located on both sides of the primary filter module 5. The bottom of the slider 8 has a protrusion that matches the groove of the guide rail 2. The surface of the protrusion is polished to further reduce the coefficient of friction. A locking element 9 is located on the top of the slider 8. The locking element 9 is controlled by rotating a handle. When the handle is rotated clockwise, the clamping part of the locking element 9 fits tightly against the groove of the guide rail 2, thereby fixing the primary filter module 5 to the main frame 1. When the handle is rotated counterclockwise, the locking element 9 is released, and the primary filter module 5 can slide along the guide rail 2 and be removed. The guide rod 10 passes through the slider 8 and the locking member 9. Both ends of the guide rod 10 are fixed to the main frame 1 by nuts to ensure that the slider 8 maintains linear motion during movement.

[0017] The high-efficiency filter module 6 is located behind the primary filter module 5. It contains a pleated filter element, which is fixed within the frame of the high-efficiency filter module 6 via slots. Positioning pins are located on both sides of the slots to prevent the filter element from shifting under airflow impact. Slider blocks 8 are also located on both sides of the high-efficiency filter module 6, and the connection between the sliders 8 and the guide rail 2 is the same as that of the primary filter module 5. The installation and removal of the high-efficiency filter module 6 are also achieved by rotating the handle of the locking component 9. When the clamping part of the locking component 9 is tightly engaged with the sliding groove of the guide rail 2, the high-efficiency filter module 6 is fixed to the main frame 1; when the locking component 9 is released, the high-efficiency filter module 6 can slide along the guide rail 2 and be removed.

[0018] The activated carbon adsorption module 7 is located behind the high-efficiency filtration module 6. It is filled with granular activated carbon arranged in layers by porous partitions. The surface of the porous partitions has ventilation holes, the diameter of which is precisely calculated to ensure uniform airflow distribution. Both sides of the activated carbon adsorption module 7 are also equipped with sliders 8, and the connection between the sliders 8 and the guide rail 2 is the same as that of other functional modules. The installation and removal of the activated carbon adsorption module 7 are also achieved by rotating the handle of the locking component 9. When the clamping part of the locking component 9 is tightly engaged with the sliding groove of the guide rail 2, the activated carbon adsorption module 7 is fixed to the main frame 1; when the locking component 9 is released, the activated carbon adsorption module 7 can slide along the guide rail 2 and be removed.

[0019] In actual operation, air enters from the front of the main frame 1 and passes sequentially through the primary filtration module 5, the high-efficiency filter module 6, and the activated carbon adsorption module 7. The metal mesh of the primary filtration module 5 intercepts large particles, while the fiber filter media further captures smaller particles. The pleated filter element of the high-efficiency filter module 6 is coated with an electrostatic coating, enhancing its ability to capture fine particles. The granular activated carbon in the activated carbon adsorption module 7 is arranged in layers through porous partitions, effectively adsorbing harmful gases and odors from the air. The air, after three stages of filtration, is discharged from the rear of the main frame 1, completing the purification process.

[0020] During maintenance, operators can quickly disassemble functional modules that need to be replaced or cleaned by rotating the handle of the locking element 9. For example, when the fiber filter media of the primary filter module 5 needs cleaning, the operator only needs to rotate the handles on both sides of the primary filter module 5 counterclockwise to loosen the locking element 9, and then slide the primary filter module 5 along the guide rail 2 and remove it. After cleaning, the primary filter module 5 is reinstalled onto the main frame 1, and the handle is rotated clockwise to make the clamping part of the locking element 9 fit tightly with the sliding groove of the guide rail 2, completing the installation. The maintenance process for the high-efficiency filter module 6 and the activated carbon adsorption module 7 is similar.

[0021] The drain groove 4 at the bottom of the main frame 1 plays a crucial role in the filtration process. When air passes through the filter, temperature changes can cause condensation. The condensate flows along the inner wall of the main frame 1 into the drain groove 4 and is discharged through the drain outlet at the bottom of the drain groove 4. The design of the drain groove 4 prevents condensate buildup from affecting the filtration effect and ensures the long-term stable operation of the filter.

[0022] This utility model's modular, combined cleanroom air filter achieves flexible adjustment and efficient maintenance through the aforementioned structural design. The rectangular structure of the main frame 1 and the parallel arrangement of the guide rails 2 provide stable support for the installation of functional modules. The cooperation of the slider 8, locking element 9, and guide rod 10 enables quick assembly and disassembly of the functional modules. The independent design of the primary filtration module 5, high-efficiency filtration module 6, and activated carbon adsorption module 7 allows for precise matching of purification needs in different areas. The design of the drainage trough 4 further enhances the overall performance of the filter. The connections between all components are clear and reliable, and all technical means can be achieved through conventional processing techniques, possessing good practicality and promotional value.

[0023] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0024] In cleanrooms, air filters typically need to be flexibly adjusted to meet the air quality requirements of different areas. For example, in a multi-module cleanroom, there are high-cleanliness areas and ordinary-cleanliness areas, and their air filtration needs differ. In this case, the modular combined cleanroom air filter of this invention can achieve its operation and maintenance process through the following steps.

[0025] First, the main frame 1 is fixed to the workshop ceiling or wall through the through holes on the end plate 3, ensuring that the rectangular structure of the main frame 1 matches the workshop environment. The guide rails 2 inside the main frame 1 are arranged in parallel and correspond to the installation requirements of the functional modules. The guide rails 2 have embedded ball bearings in their grooves, which significantly reduces friction during the movement of the functional modules, thereby improving the efficiency of installation and disassembly. Operators select the combination of the primary filtration module 5, the high-efficiency filter module 6, and the activated carbon adsorption module 7 according to actual needs. For example, for high-cleanliness areas, the primary filtration module 5, the high-efficiency filter module 6, and the activated carbon adsorption module 7 can be installed simultaneously; while for ordinary cleanliness areas, only the primary filtration module 5 and the high-efficiency filter module 6 need to be installed.

[0026] Subsequently, the operator slides the primary filter module 5 along the guide rail 2 to the front end of the main frame 1. The bottom of the sliders 8 on both sides of the primary filter module 5 has protrusions that match the grooves of the guide rail 2. The locking member 9 at the top of the slider 8 is controlled by rotating a handle. When the handle is rotated clockwise, the clamping part of the locking member 9 fits tightly against the groove of the guide rail 2, thus fixing the primary filter module 5 to the main frame 1. A guide rod 10 passes through the slider 8 and the locking member 9 and is fixed to the main frame 1 with a nut to ensure that the slider 8 maintains a straight line during movement and avoids deviation. The metal mesh cover of the primary filter module 5 intercepts large particles of impurities, and the internal fiber filter media further captures smaller particles, thus completing the first stage of filtration.

[0027] Next, the high-efficiency filter module 6 is installed behind the primary filter module 5. The pleated filter element of the high-efficiency filter module 6 is fixed within the module frame via slots, and locating pins on both sides of the slots effectively prevent the filter element from shifting under airflow impact. The installation method of the high-efficiency filter module 6 is the same as that of the primary filter module 5: after the slider 8 slides along the guide rail 2 to the designated position, the locking element 9 is fixed by rotating the handle. The surface of the pleated filter element of the high-efficiency filter module 6 is coated with an electrostatic coating, which enhances its ability to capture fine particles, thereby achieving secondary filtration.

[0028] Finally, for areas requiring the removal of harmful gases and odors, the operator installs the activated carbon adsorption module 7 behind the high-efficiency filter module 6. The activated carbon adsorption module 7 is filled with granular activated carbon, arranged in layers by porous partitions. The air vents on the surface of these partitions are precisely calculated to ensure uniform airflow distribution. The activated carbon adsorption module 7 is also installed using sliders 8 and locking devices 9, making operation simple and reliable. The air, after three stages of filtration, is discharged from the rear of the main frame 1, completing the entire purification process.

[0029] During filter operation, changes in air temperature may cause condensation. The condensate flows along the inner wall of the main frame 1 into the drain trough 4 and is discharged through the drain outlet at the bottom of the drain trough 4. The design of the drain trough 4 prevents condensate buildup from affecting the filtration effect and ensures long-term stable operation of the filter. Furthermore, the drain trough 4 extends in the same direction as the length of the main frame 1, facilitating rapid condensate drainage and further improving the overall performance of the filter.

[0030] When a functional module needs maintenance or replacement, the operator simply rotates the handles on both sides of the corresponding module counterclockwise to loosen the locking element 9, then slides the module along the guide rail 2 and removes it. For example, when the fiber filter media of the primary filter module 5 needs cleaning, the operator removes the primary filter module 5, uses the clips to remove the metal mesh cover, cleans the fiber filter media, and reinstalls it. After cleaning, the primary filter module 5 is slid back onto the main frame 1, and the handles are rotated clockwise to ensure the clamping part of the locking element 9 fits tightly against the groove of the guide rail 2, completing the installation. The maintenance process for the high-efficiency filter module 6 and the activated carbon adsorption module 7 is similar.

[0031] Through the above steps, this utility model achieves rapid disassembly, assembly, and flexible adjustment of a modular, combined cleanroom air filter. The rectangular structure of the main frame 1 and the parallel arrangement of the guide rails 2 provide stable support for the installation of functional modules, while the cooperation of the slider 8, locking parts 9, and guide rods 10 significantly improves maintenance efficiency. The independent design of the primary filtration module 5, the high-efficiency filtration module 6, and the activated carbon adsorption module 7 allows for precise matching of purification needs in different areas, while the design of the drainage trough 4 further enhances the overall performance of the filter. The connections between all components are clear and reliable, and all technical means can be achieved through conventional processing techniques, possessing good practicality and promotional value.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
