Description

Technical Field

[0001] This invention relates to the field of energy-saving and cleaning appliance technology, specifically to a high-efficiency energy-saving FFU filter with static electricity removal function. Background Technology

[0002] As a core device for clean environment control, FFU (High-Efficiency Fusion Filter) is widely used in fields with extremely high requirements for air cleanliness and electrostatic protection, such as electronic semiconductors, biomedicine, optoelectronic displays, and precision instrument manufacturing. It drives airflow through a built-in fan, allowing air to flow through the primary filter, high-efficiency filter material, and other filtration components in sequence, intercepting large dust particles, fine particulate matter, microbial aerosols, and other pollutants in the air step by step, and finally outputting clean air that meets the cleanliness level requirements to the target area. In practical applications, dust particles in the area are prone to generating static electricity during airflow, equipment operation friction, and material handling. When filtering, charged dust particles are easily adsorbed by electrostatic adsorption and adhere tightly to the pore surface of the FFU's high-efficiency filter media. Not only is it difficult to be carried away by the airflow, but it will also quickly block the filter media channels, resulting in increased filter media resistance and reduced ventilation. This not only affects the service life of the filter media, but also increases the maintenance and use costs of the filter. In view of this, we propose an FFU (Fan Filter Unit) with static electricity removal function for high efficiency and energy saving. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides an FFU (Fan Filter Unit) high-efficiency energy-saving filter with antistatic function. This effectively solves the problem that dust generates static electricity during filtration due to airflow and equipment friction, which then adheres to the pores of the FFU high-efficiency filter material through electrostatic adsorption and blocks the channels, leading to a shortened filter material lifespan and increased maintenance costs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a high-efficiency energy-saving FFU filter with antistatic function, comprising a main unit including a housing, a control box disposed on the housing, and a filtration mechanism disposed on the housing, including... The static eliminator includes an ion bar mounted on the housing for neutralizing the FFU airflow and dust and static charge on the equipment surface within the clean area; a drive mechanism mounted on the control box for oscillating the ion bar; and an adjustment control mechanism mounted on the control box for adjusting the oscillation amplitude and output power of the ion bar.

[0005] Furthermore, the filtration mechanism includes a filter screen fixedly connected to the input end of the housing, a centrifugal fan provided on one side of the filter screen, and the surface of the centrifugal fan fixedly connected to the inner wall of the housing.

[0006] Furthermore, a filter body is provided on the side of the centrifugal fan away from the filter screen, and the surface of the filter body is fixedly connected to the output end of the housing.

[0007] Furthermore, the drive mechanism includes a motor fixedly connected to the inner wall of the control box, a crank fixedly connected to the motor via an output shaft, and a lever rotatably connected to the end of the crank away from the motor.

[0008] Furthermore, a connecting rod is rotatably connected to the end of the lever away from the crank, and a rack is rotatably connected to the end of the connecting rod away from the lever. A guide rail is slidably connected to one side of the rack, and one side of the guide rail is fixedly connected to the inner wall of the control box.

[0009] Furthermore, a gear is meshed with the radial side of the rack, the axial side of the gear is rotatably connected to the inner wall of the control box, and a fixed shaft is fixedly connected to the other axial side of the gear.

[0010] Furthermore, the fixed shaft rotates through the control box and extends into the interior of the housing at the end away from the gear, and the end of the fixed shaft extending into the housing is fixedly connected to one end of the ion air bar, while the end of the ion air bar away from the fixed shaft is rotatably connected to the inner wall of the housing.

[0011] Furthermore, the adjustment and control mechanism includes a fixed frame fixedly connected to the inner wall of the control box, a second motor fixedly connected to one side of the fixed frame, a lead screw fixedly connected to the second motor via an output shaft, an adjustment frame threaded onto the surface of the lead screw, a guide rod slidably connected to the inner wall of the adjustment frame, and both ends of the guide rod fixedly connected to the inner wall of the fixed frame.

[0012] Furthermore, the adjustment and control mechanism also includes a groove on the surface of the lever, with a slider slidably connected to the inner wall of the groove, and one side of the slider being rotatably connected to one side of the adjustment frame.

[0013] Furthermore, a sliding rheostat for controlling the output power of the ion fan bar is fixedly connected to the inner wall of the fixed frame. The sliding rheostat is fixedly connected to the side of the adjustment frame away from the slider via a sliding contact. The two fixed terminals of the sliding rheostat are electrically connected to the positive and negative terminals of the high-voltage power supply, respectively, and the sliding terminal of the sliding rheostat is electrically connected to the power input terminal of the ion air bar.

[0014] The technical solution provided by this invention has the following advantages compared with known public technologies: This invention integrates a swing-type static eliminator structure with a filter component. A drive mechanism rotates the ion bar back and forth, expanding the ion coverage area and achieving uniform static elimination throughout the clean area. This effectively neutralizes static charges on airflow, dust, and equipment surfaces, preventing the adsorption of charged dust and ensuring equipment stability. Simultaneously, a control mechanism allows for synchronized adjustment of the ion bar's swing amplitude and output power. Operating parameters are dynamically matched based on dust concentration and static intensity. Under high load conditions, power and swing amplitude are increased to enhance the static eliminator effect, while energy consumption is reduced under low load conditions. This avoids static residue and energy waste, and prevents excessive ions from generating ozone pollution. It not only effectively improves static efficiency but also ensures a safe working environment. Neutralized dust loses its adsorption capacity, making it less likely to clog filter media pores. Furthermore, the swinging airflow disturbs dust accumulation on the filter media surface, extending its lifespan, reducing maintenance costs, and ensuring its permeability, further improving the purification and filtration effect.

[0019] The present invention will be further described below with reference to embodiments.

[0020] like Figures 1 to 7 As shown, a high-efficiency energy-saving FFU filter with static electricity removal function includes a main unit 100, including a housing 101, a control box 102 disposed on the housing 101, and a filter mechanism 103 disposed on the housing 101. The filter mechanism 103 includes a static electricity removal unit 200, comprising an ionizer 201 disposed on the housing 101 for neutralizing the FFU airflow and dust and static charge on the equipment surface within the clean area; a drive mechanism 202 disposed on the control box 102 for oscillating the ionizer 201; and an adjustment control mechanism 203 disposed on the control box 102 for adjusting the oscillation amplitude and output power of the ionizer 201. Small; the housing 101 is made of 304 stainless steel, which has the characteristics of corrosion resistance and high strength, and provides a stable installation space for internal components. The control box 102 is fixed to the outer wall of one side of the housing 101 by bolts. The core components of the drive mechanism 202 and the adjustment control mechanism 203 are integrated inside. An operation panel is provided on the outside for equipment start-up and shutdown and parameter adjustment. The filter mechanism 103 is installed inside the housing 101 and arranged along the airflow direction to achieve high-efficiency filtration and graded purification. In the static electricity removal unit 200, the ion bar 201 is installed inside the housing 101. It generates positive and negative ions through high voltage discharge to accurately neutralize the static charge of dust and equipment surface in the FFU airflow and clean area. Specifically, refer to Figure 2The filtration mechanism 103 includes a filter screen 1031 fixedly connected to the input end of the housing 101. A centrifugal fan 1032 is provided on one side of the filter screen 1031, and the surface of the centrifugal fan 1032 is fixedly connected to the inner wall of the housing 101. A filter body 1033 is provided on the side of the centrifugal fan 1032 away from the filter screen 1031, and the surface of the filter body 1033 is fixedly connected to the output end of the housing 101. The filter screen 1031 is made of metal and is fixed to the air inlet at the input end of the housing 101 by clips. Its main function is to intercept large particles of dust, hair, and other impurities in the air, preventing large particulate pollutants from entering subsequent components and causing wear or blockage. A centrifugal fan 1032 is installed on the side of the filter screen 1031 near the inside of the housing 101. The centrifugal fan 1032 is a low-power DC brushless fan of model YWF4E-300. The housing is fixed to the inner wall of the housing 101 by bolts. The air inlet end maintains a corresponding distance from the filter screen 1031 to ensure smooth air intake. A filter body 1033 is installed on the side of the centrifugal fan 1032 away from the filter screen 1031. The filter body 1033 uses pleated HEPA high-efficiency filter material. The edges are tightly fitted to the inner wall of the output end of the housing 101 by foamed rubber sealing strips. The surface is fixed by pressure strips and bolts to prevent leakage of unfiltered airflow. It should be noted that during operation, the centrifugal fan 1032 generates negative pressure after starting, drawing outside air into the housing 101. The air first undergoes preliminary filtration through the filter screen 1031 to remove large particulate impurities, then flows through the centrifugal fan 1032 for acceleration, and finally undergoes high-efficiency filtration through the filter body 1033 to remove fine dust, microorganisms and other pollutants. The purified air is discharged from the output end of the housing 101 to the clean area. Specifically, refer to Figures 2 to 6The drive mechanism 202 includes a motor 2027 fixedly connected to the inner wall of the control box 102. A crank 2026 is fixedly connected to the motor 2027 via an output shaft. A lever 2025 is rotatably connected to the end of the crank 2026 away from the motor 2027. A connecting rod 2023 is rotatably connected to the end of the lever 2025 away from the crank 2026. A rack 2028 is rotatably connected to the end of the connecting rod 2023 away from the lever 2025. A guide rail 2024 is slidably connected to one side of the rack 2028. One side of the guide rail 2024 is fixedly connected to the inner wall of the control box 102. The radial side of the rack 2028 is engaged with... There is a gear 2022, one axial side of which is rotatably connected to the inner wall of the control box 102, and the other axial side of the gear 2022 is fixedly connected to a fixed shaft 2021. The end of the fixed shaft 2021 away from the gear 2022 rotates through the control box 102 and extends into the interior of the housing 101. The end of the fixed shaft 2021 extending into the housing 101 is fixedly connected to one end of the ion fan bar 201. The end of the ion fan bar 201 away from the fixed shaft 2021 is rotatably connected to the inner wall of the housing 101. Motor 2027 is a stepper motor of model 57BYG250, which is fixedly connected to the control box 102 via a motor mount. The inner wall of the housing 102 is such that the output shaft of motor 2027 is fixedly connected to one end of crank 2026 via a coupling. The end of crank 2026 away from motor 2027 is rotatably connected to the middle of lever 2025 via a pin.

One side of rack 2028 is slidably connected to guide rail 2024 via slider 2033, ensuring that rack 2028 performs linear reciprocating motion along guide rail 2024. The radial direction of rack 2028... The gear 2022 is meshed with the gear 2022. One axial side of the gear 2022 is rotatably connected to the inner wall of the control box 102 via a deep groove ball bearing, and the other axial side is fixedly connected to the fixed shaft 2021 via a flat key. The end of the fixed shaft 2021 away from the gear 2022 is rotatably passed through the side wall of the control box 102 and the side wall of the housing 101 via a bearing, and extends into the interior of the housing 101. The end of the fixed shaft 2021 extending into the interior of the housing 101 is fixedly connected to one end of the ion air bar 201 via a set screw. The end of the ion air bar 201 away from the fixed shaft 2021 is rotatably connected to the inner wall of the housing 101 via a bearing seat. It should be noted that during operation, after the motor 2027 starts, it drives the crank 2026 to rotate. The crank 2026 pulls the lever 2025 to swing around the central hinge point through the pin shaft. The lever 2025 drives the connecting rod 2023 to push and pull. The connecting rod 2023 drives the rack 2028 to move linearly back and forth along the guide rail 2024. The rack 2028 drives the meshing gear 2022 to rotate alternately in forward and reverse directions. The gear 2022 drives the fixed shaft 2021 to rotate synchronously, thereby driving the ion wind bar 201 to swing back and forth around the fixed shaft 2021 as the axis. Specifically, refer to Figures 2 to 7The adjustment and control mechanism 203 includes a fixed frame 2031 fixedly connected to the inner wall of the control box 102. A motor 2038 is fixedly connected to one side of the fixed frame 2031. A lead screw 2037 is fixedly connected to the motor 2038 via an output shaft. An adjustment frame 2035 is threaded onto the surface of the lead screw 2037. A guide rod 2036 is slidably connected to the inner wall of the adjustment frame 2035. Both ends of the guide rod 2036 are fixedly connected to the inner wall of the fixed frame 2031. The adjustment and control mechanism 203 also includes a groove 2032 formed on the surface of a lever 2025. A slider 2033 is slidably connected to the inner wall of the groove 2032. One side of the slider 2033 is rotated... A sliding rheostat 2034 for controlling the output power of the ion bar 201 is fixedly connected to one side of the adjusting frame 2035 and the inner wall of the fixed frame 2031. The sliding rheostat 2034 is fixedly connected to the side of the adjusting frame 2035 away from the slider 2033 via a sliding contact. The two fixed terminals of the sliding rheostat 2034 are electrically connected to the positive and negative terminals of the high-voltage power supply, respectively, and the sliding terminal of the sliding rheostat 2034 is electrically connected to the power input terminal of the ion bar 201. The fixed frame 2031 is made of angle steel welded together and fixedly connected to the inner wall of the control box 102 by bolts. One side of the fixed frame 2031 is connected to a motor mount. A second motor 2038 is fixedly connected. Motor 2038 is a 42BYG250 stepper motor. The output shaft of motor 2038 is fixedly connected to a lead screw 2037 via a coupling. An adjusting frame 2035 is threaded onto the surface of the lead screw 2037. A guide rod 2036 is slidably connected to the inner wall of the adjusting frame 2035 via a linear bearing. Both ends of the guide rod 2036 are fixedly connected to the inner wall of the fixed frame 2031 with nuts, ensuring that the adjusting frame 2035 moves smoothly in a straight line along the guide rod 2036. The adjustment control mechanism 203 is linked to the drive mechanism 202 via a groove 2032 on the surface of the lever 2025. The inner wall of the slide groove 2032 is connected to the adjusting frame 2035 via the slider 2033. One side of the slider 2033 is rotatably connected to one side of the adjusting frame 2035 via a pin, and the other side is embedded in the slide groove 2032 and can slide along the slide groove 2032. The inner wall of the fixed frame 2031 is also fixedly connected to a sliding rheostat 2034. The sliding rheostat 2034 is a high-voltage sliding rheostat 2034 of model WS20-10W, which is fixed to the fixed frame 2031 by a buckle. The sliding contact of the sliding rheostat 2034 is fixedly connected to the side of the adjusting frame 2035 away from the slider 2033 by bolts, and moves synchronously with the adjusting frame 2035. It should be noted that the two fixed terminals of the sliding rheostat 2034 are electrically connected to the positive and negative terminals of the high-voltage power supply via high-voltage wires, respectively. The sliding terminal of the sliding rheostat 2034 is electrically connected to the power input terminal of the ion bar 201 via a high-voltage wire. When the swing amplitude needs to be adjusted, the motor 2038 starts, driving the lead screw 2037 to rotate. The lead screw 2037 drives the adjusting frame 2035 to move back and forth along the guide rod 2036. The adjusting frame 2035, through the slider 2033, causes the position of the swing fulcrum of the lever 2025 to change, thereby changing the position of the lever 2025. The lever arm ratio of 5 allows for adjustment of the swing amplitude of the ion bar 201. Simultaneously, the movement of the adjustment frame 2035 moves the sliding contact of the sliding rheostat 2034, changing the resistance value of the rheostat 2034 connected to the circuit, thereby changing the input voltage of the ion bar 201 and adjusting the output power. A decrease in resistance increases the input voltage, resulting in increased output power and a greater amount of ions generated, while also increasing the swing amplitude. Conversely, an increase in resistance decreases the input voltage, resulting in decreased output power, a smaller amount of ions generated, and a smaller swing amplitude, thus adapting to different static electricity elimination needs.

[0021] The working principle of this invention: After the equipment is started, the centrifugal fan 1032 in the main unit 100 runs first, generating a stable negative pressure to draw external air into the housing 101. The air first flows through the filter screen 1031 at the input end of the housing 101 to complete the initial filtration process, intercepting large particles of dust, hair and other impurities in the air, avoiding wear or blockage of the subsequent high-efficiency filter material and fan components due to large particulate pollutants, and extending the service life of the core components; After primary filtration, the air is accelerated by the centrifugal fan 1032 and then undergoes efficient purification through the filter body 1033. The pleated HEPA filter material, with its ultra-large filtration area and high filtration accuracy, intercepts pollutants such as fine dust and microbial aerosols, ensuring that the exhaust air meets the requirements for use in clean areas. During the filtration process, the static electricity removal unit 200 is started simultaneously. After the ion bar 201 is connected to the high voltage power supply, it releases positive and negative ions through the discharge needle to neutralize the static charge on the airflow output by the FFU and the dust and equipment surface in the clean area. During use, motor 1 2027 starts, and the output shaft drives crank 2026 to make circular motion. Crank 2026 pulls lever 2025 to swing back and forth around the central hinge point through pin. The other end of lever 2025 drives rack 2028 to make linear reciprocating motion along guide rail 2024 through connecting rod 2023. Rack 2028 meshes with gear 2022 to drive gear 2022 to rotate alternately in forward and reverse directions. In turn, it drives ion wind bar 201 to swing back and forth around fixed shaft 2021 as the axis through fixed shaft 2021, thereby expanding the ion coverage area. The ion bar 201 reciprocates, allowing the ion airflow to spread evenly over a larger area, increasing coverage and ensuring that static electricity in all areas is quickly neutralized. This prevents dust from adhering to product surfaces or equipment walls due to static electricity, thus ensuring product yield and reducing secondary dust pollution to the clean environment. During use, the motor 2038 of the adjustment control mechanism 203 can be used. After receiving the control signal, the motor 2038 starts and the output shaft drives the lead screw 2037 to rotate through the coupling. Since the adjustment frame 2035 is threadedly connected to the lead screw 2037 and the inner wall of the adjustment frame 2035 is slidably engaged with the guide rod 2036 through the linear bearing, the rotational motion of the lead screw 2037 is converted into the smooth linear motion of the adjustment frame 2035 along the guide rod 2036. One side of the adjusting frame 2035 is rotatably connected to the slider 2033 via a pin, and the slider 2033 is embedded in the groove 2032 opened on the surface of the lever 2025 and can slide along the groove 2032. When the adjusting frame 2035 moves forward along the guide rod 2036, the slider 2033 slides in the groove 2032, causing the swing fulcrum of the lever 2025 to move closer to the crank 2026. According to the lever 2025 principle, the swing stroke of the other end of the lever 2025 increases. Through the transmission of the connecting rod 2023, rack 2028, and gear 2022, the swing angle of the ion wind bar 201 increases accordingly. Conversely, when the adjusting frame 2035 moves backward along the guide rod 2036, the slider 2033 drives the swing fulcrum of the lever 2025 to move away from the crank 2026, the swing stroke of the other end of the lever 2025 decreases, and the swing angle of the ion wind bar 201 decreases synchronously, thereby realizing the adjustment of the swing amplitude. Furthermore, the sliding rheostat 2034, which is fixed to the inner wall of the fixed frame 2031, has its sliding contact piece fixedly connected to the side of the adjusting frame 2035 away from the slider 2033 by bolts, and moves synchronously with the adjusting frame 2035. In terms of circuit connection, the two fixed terminals of the sliding rheostat 2034 are electrically connected to the positive and negative terminals of the high voltage power supply through high voltage wires, respectively, and the sliding terminal is electrically connected to the power supply input terminal of the ion wind bar 201 through high voltage wires. When the adjusting frame 2035 moves forward, the sliding contact moves closer to one of the fixed terminals of the sliding rheostat 2034, reducing the resistance of the circuit. According to Ohm's law, the input voltage of the ion bar 201 increases, the output power increases, and the number of positive and negative ions generated per unit time increases. When the adjusting frame 2035 moves backward, the sliding contact moves in the opposite direction, increasing the resistance of the circuit. The input voltage of the ion bar 201 decreases, the output power decreases, and the amount of ions generated decreases, thus achieving precise adjustment of the output power. In actual use, the adjustment and control mechanism 203 can be dynamically adjusted according to the dust concentration and static electricity intensity of the clean area. For example, when the dust concentration in the clean area is high, such as near the electronic component polishing process or when a large amount of static electricity is generated during equipment operation, such as during semiconductor chip handling or LCD panel assembly, the control motor 2038 rotates forward, driving the adjustment frame 2035 to move forward, and simultaneously increasing the swing amplitude of the ion bar 201 to expand the ion coverage area. At the same time, the output power increases, increasing the amount of ions generated, which can quickly neutralize high concentrations of charged dust and static electricity on the equipment surface, avoiding product defects caused by static adsorption. Conversely, when the dust concentration in the clean area is low and the amount of static electricity generated is small, such as in a precision instrument storage room or a sterile laboratory, the control system drive motor 2038 can be reversed, the adjustment frame 2035 can be moved backward, the oscillation amplitude of the ion bar 201 can be reduced, and the output power can be reduced, which reduces unnecessary energy consumption and avoids excessive ion discharge to generate ozone, thus ensuring the safety of the clean environment. With the synergistic effect of static elimination and filtration, the ion bar 201 neutralizes the static charge on the surface of the dust, causing the dust to lose its adsorption capacity and become less likely to adhere to the pores of the filter media in the filter body 1033. This effectively reduces filter media clogging and extends the filter media replacement cycle. At the same time, the oscillating ion airflow can slightly disturb the airflow on the surface of the filter media, blowing away some of the adsorbed dust clumps and maintaining the permeability of the filter media. This ensures that the centrifugal fan 1032 can maintain a stable airflow without additional power, reducing the fan's operating energy consumption. Furthermore, it can dynamically match energy consumption according to actual working conditions, avoiding continuous high-load operation. While reducing energy consumption, it can also further improve the purification and filtration effect.
