Description

Technical Field

[0001] The present invention relates to the technical field of air purification and filtration, and particularly to a multi-layer composite air purification and filtration system for a clean room. Background Art

[0002] The multi-layer composite air purification and filtration system for a clean room consists of multiple filtration units, usually including a primary filter, a medium-efficiency filter, a high-efficiency filter, and an activated carbon adsorption layer, etc., forming a multi-layer purification structure with distinct levels. First, air passes through the primary filter to remove large particulate matter such as dust and hair, reducing the burden on subsequent filters. The air passes through the high-efficiency filter to remove fine particulate matter, bacteria, viruses, etc., ensuring clean air. Some systems are also equipped with an activated carbon adsorption layer to remove harmful gases and volatile organic compounds in the air. This multi-layer composite structure can effectively filter various pollutants in the air, ensuring that the air quality in the clean room reaches an extremely high standard and meets the requirements of special environments.

[0003] Although this system has excellent purification effects in clean room applications, there are still some defects. The air resistance brought by the high-efficiency filter and the fan in the system is relatively high. Especially during long-term operation, the energy efficiency problem is particularly prominent. The fan needs to provide stronger wind power to maintain the air flow rate and filtration effect. This not only increases energy consumption, but the excessive air resistance may affect the uniformity of air flow, resulting in unsatisfactory air purification effects in some areas. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a multi-layer composite air purification and filtration system for a clean room, which solves the problem that the excessive air resistance brought by the high-efficiency filter and the fan affects the uniformity of air flow, resulting in unsatisfactory air purification effects in some areas.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A multi-layer composite air purification and filtration system for a clean room, comprising:

[0006] A base, on which a lower bracket is fixed. A plurality of air outlets are provided on the lower bracket. A collection box is fixed on the upper side of the base. A vibration rod is arranged inside the collection box. An air outlet pipe is arranged outside the lower bracket;

[0007] The inside of the lower bracket is detachably connected with a filter housing. A heating sheet is fixed inside the filter housing. A shape memory alloy adsorption grid is filled inside the heating sheet;

[0008] A power assembly, which is located inside the filter housing. The power assembly includes an air inlet mechanism, a motor, and a first support frame;

[0009] Dynamic corrugated filter device, the dynamic corrugated filter device includes a support assembly and a filter assembly.

[0010] Preferably: A switch is provided on the side surface of the base, and a power port is provided on the base.

[0011] Preferably: A cavity is provided inside the shape memory alloy adsorption grid, and the upper end of the vibration rod contacts the cavity.

[0012] Preferably: A limiting piece is fixedly connected inside the filter housing, a second support frame is provided below the limiting piece inside the filter housing, and an installation groove is provided below the second support frame inside the filter housing.

[0013] Preferably: The air inlet mechanism is fixed to the filter housing, the motor is fixedly connected to the air inlet mechanism, and the output end of the motor is fixed to the first support frame.

[0014] Preferably: The support assembly includes a movable piece, a lower top cover, a chute and a support rod. The support rod is fixed to the lower top cover, the chute is located on the lower top cover, and the movable piece is sleeved on the chute.

[0015] Preferably: The filter assembly includes an upper top cover, an air inlet hole, a corrugated filter and an elastic ring. The air inlet hole is located on the upper top cover and extends into the inside of the corrugated filter. The lower side of the upper top cover is fixedly connected to the corrugated filter. The corrugated filter is corrugated. The lower side of the corrugated filter is fixedly connected to the elastic ring, and the elastic ring is sleeved on the movable piece.

[0016] Preferably: An upper side cover plate is provided on the upper side of the filter housing, and a plurality of air inlets are provided on the upper side cover plate. The air inlets are inclinedly distributed.

[0017] The present invention provides a multi-layer composite air purification and filtration system for a clean room. It has the following beneficial effects:

[0018] This multi-layer composite air purification and filtration system for a clean room adopts a number of innovative structural designs. In addition to the dynamic corrugated filter device, it also includes core components such as a shape memory alloy adsorption grid, a vibration rod, a heating sheet, etc., further improving the filtration efficiency and system stability.

[0019] The shape memory alloy adsorption grid can automatically adjust the pore size according to the change of air quality, enhancing the adaptive ability of the filter. When the concentration of pollutants in the air is high, the grid will expand to increase the filtration area, thereby enhancing the adsorption ability; when the pollutant concentration is low, the grid will contract, reducing energy consumption and maintaining smooth air circulation. The vibration rod is used in combination with the adsorption grid for cleaning, and the heating sheet is combined with the grid to adjust the size of the cavity.

[0020] The cooperation between the air inlet mechanism and the motor can stabilize the air flow rate, avoiding problems such as reduced filtration efficiency or poor local purification effect caused by too fast air speed. The support component can effectively support the corrugated filter, ensuring that the filtering device remains stable during operation, and avoiding uneven air flow or unstable filtering effect caused by filter deformation or displacement. Through the synergistic effect of these designs, the entire system not only improves the air purification effect, but also enhances the durability and maintainability of the system.

[0044] As Figure 1-8 As shown in the figure, an embodiment of the present invention provides a multi-layer composite air purification and filtration system for a clean room, including a base 1, on which a lower bracket 4 is fixed. A plurality of air outlets 2 are provided on the lower bracket 4. A collection box 26 is fixed on the upper side of the base 1, and a vibrating rod 27 is arranged inside the collection box 26.

[0046] A power assembly 7 is located inside the filter housing 5. The power assembly 7 includes an air inlet mechanism 8, a motor 9 and a first support frame 10.

[0047] Dynamic corrugated filter device 11, the dynamic corrugated filter device 11 includes a support assembly and a filter assembly. The support assembly includes a movable piece 16, a lower top cover 17, a chute 18 and a support rod 19. The support rod 19 is fixed to the lower top cover 17. The chute 18 is located on the lower top cover 17. The movable piece 16 is sleeved on the chute 18. The filter assembly includes an upper top cover 12, an air inlet hole 13, a corrugated filter 14 and an elastic ring 15. The air inlet hole 13 is located on the upper top cover 12 and extends into the interior of the corrugated filter 14. The lower side of the upper top cover 12 is fixedly connected to the corrugated filter 14. The corrugated filter 14 is corrugated. The lower side of the corrugated filter 14 is fixedly connected to the elastic ring 15. The elastic ring 15 is sleeved on the movable piece 16. The upper side of the filter housing 5 is provided with an upper side cover plate 6. A plurality of air inlets 29 are provided on the upper side cover plate 6. The air inlets 29 are inclinedly distributed.

[0048] In this embodiment, on the basis of the dynamic corrugated filter device 11, the support assembly and the filter assembly are further optimized, enhancing the flexibility and stability of the system. The cooperation of the movable piece 16, the lower top cover 17, the chute 18 and the support rod 19 enables the filter device to achieve dynamic adjustment according to the change of air flow rate, ensuring that the filter maintains a stable shape and efficient filtering effect during operation. The combination of the corrugated filter 14 and the elastic ring 15 improves the sealing performance, avoids air leakage, and enhances the filtering efficiency. At the same time, the design of the limiting piece 20 and the installation groove 22 enhances the stability of the filter assembly, avoids displacement or loosening, and ensures continuous high-efficiency filtering effect. The multiple inclined air inlets 29 provided on the upper side cover plate 6 guide the air to flow in evenly, optimize the air flow path, and improve the air purification effect.

[0049] Working principle: Air first enters the system through several air outlets 2 located on the base 1. Driven by the air inlet mechanism 8 and the motor 9, the air is guided into the filter housing 5 and flows through the system at a stable flow rate. The close connection between the air inlet mechanism 8 and the motor 9 ensures the uniformity of the air flow rate, avoiding the phenomenon of uneven air flow, and thus ensuring the stability of the filtration effect. After the air enters the filter housing 5, it first passes through the heating sheet 25 fixed inside the housing. The heating sheet 25 adsorbs the shape memory alloy adsorption grid 23 through heating. The air passes through the shape memory alloy adsorption grid 23, which can automatically adjust its shape according to the change of air quality to optimize the filtration effect. When the pollutant concentration is high, the shape memory alloy grid will automatically expand to increase the surface area, thereby improving the filtration capacity. The vibrating rod 27 contacts the cavity 24 inside the grid, generating a vibrating effect to clean the surface of the grid, preventing the grid from being blocked due to the accumulation of particulate matter and ensuring a continuous and efficient filtration effect. After passing through the filtration of the shape memory alloy grid, the air continues to flow through the dynamic corrugated filter device 11, which includes a support assembly and a filter assembly. The corrugated filter 14 is combined with the elastic ring 15 to improve the sealing performance of the filter, avoiding air leakage and enhancing the filtration effect. The combination of the movable piece 16, the lower top cover 17, the sliding groove 18 and the support rod 19 in the support assembly enables the filter device to dynamically adjust according to the change of air flow rate, thereby maintaining the stability and high-efficiency filtration performance of the system. The purified air is discharged through the multiple air inlets 29 of the filter housing 5. The air inlets 29 on the upper side cover 6 are inclinedly distributed, reasonably guiding the air into the filter, optimizing the air flow path, ensuring the uniform distribution of air throughout the filtration system, and further improving the purification efficiency. Finally, the purified air is discharged through the air outlet 2 on the lower side of the base 1 to ensure that the air quality in the clean room reaches a high standard.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
