Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air purification device for cleanrooms. Background Technology

[0002] A cleanroom, also known as a dust-free workshop, clean room, or clean room, is a sealed room that has strict requirements for air temperature, humidity, pressure, and especially dust concentration. Cleanrooms require air purification devices to purify the air during ventilation.

[0003] A search of utility model patent publication number CN208794604U reveals an air purification device for cleanrooms. This device uses an ultraviolet germicidal lamp to sterilize the air and remove bacteria, a filter cotton to filter dust, and activated carbon to adsorb bacteria and dust for further air treatment. However, it has certain problems in use. When dealing with solid impurities (dust), the airflow passes through the filter cotton and activated carbon sequentially, with the filter cotton located below the activated carbon and contacting the dust first. While the filter cotton can filter and intercept dust, after prolonged use, a significant amount of dust accumulates on it. This dust buildup not only affects air permeability but can also cause blockages, impacting ventilation. Furthermore, when cleaning the intercepted dust, the filter cotton and the first filter plate block the dust, causing it to fall into the lower chamber, making cleaning difficult. Additionally, the intercepted dust easily adheres to the surface of the ultraviolet germicidal lamp, affecting its sterilization effect. Therefore, this application proposes an air purification device for cleanrooms. Utility Model Content

[0004] The purpose of this invention is to provide an air purification device for clean rooms, which addresses the problem that existing purification devices are not convenient for quickly cleaning up trapped dust and impurities, thus affecting ventilation.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An air purification device for cleanrooms, comprising:

[0007] The purification shell has an air inlet pipe and an air outlet pipe symmetrically connected to it. A motor is installed on one side of the purification shell. The output shaft of the motor is fixed with a disc located inside the purification shell. An annular filter cylinder is installed on one side of the disc. There is an annular gap between the annular filter cylinder and the purification shell. The inner wall of the purification shell is provided with two sealing blocks whose ends overlap with the outer wall of the annular filter cylinder.

[0008] The dust removal mechanism includes a water storage tank connected to the purification shell, a conveying pipe connected to the water storage tank, the free end of the conveying pipe extending into the purification shell and connected to a water spraying component, and a water pump installed on the purification shell connected to the conveying pipe.

[0009] The adsorption and purification element is installed on the purification shell and located inside the annular filter cartridge.

[0010] Furthermore, the water spray component includes a main pipe connected to the delivery pipe, a plurality of secondary pipes connected in an array along the length of the main pipe, and a plurality of nozzles connected in an array along the length of the secondary pipes.

[0011] Furthermore, a mesh cover is provided inside the water storage shell to cover the connection port of the delivery pipe.

[0012] Furthermore, two partitions are provided on the inner wall of the purification shell on the side away from the motor, and both ends of the partitions are in contact with and overlap the inner wall of the annular filter cartridge.

[0013] Furthermore, the adsorption and purification element includes a mesh bag disposed on the inner wall of the purification shell, the mesh bag being located between two partitions and containing activated carbon.

[0014] Furthermore, a high-flux pulsed xenon lamp is provided on the inner wall of the purification shell, and the high-flux pulsed xenon lamp is located between two partitions.

[0015] Furthermore, a through slot is provided on one side of the purification shell, and a cover plate is provided on the purification shell to seal the through slot. The mesh bag and the high-flux pulsed xenon lamp are both provided on the cover plate.

[0016] Furthermore, the inner wall of the water storage shell is provided with a support plate, and the support plate is provided with an array of bristles whose ends overlap with the outer wall of the annular filter cylinder.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, by rotating the annular filter cartridge inside the purification shell, the annular filter cartridge filters and intercepts dust in the air as it rotates. As the annular filter cartridge continues to rotate, water is sprayed from inside the annular filter cartridge outward, washing the dust adhering to the surface of the annular filter cartridge into the water storage shell. This allows the annular filter cartridge to be quickly cleaned while filtering and intercepting dust. After being cleaned, it rotates again to intercept dust in the air. While ensuring the filtration and interception of airflow, it facilitates the flow of airflow, making it less prone to clogging. At the same time, opening the drain pipe facilitates the cleaning of wastewater and dust, thereby improving practicality. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] This embodiment provides an air purification device for cleanrooms, mainly to solve the problem that existing purification devices are inconvenient to quickly clean up trapped dust and impurities, thus affecting ventilation. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-7 Please provide a detailed explanation:

[0028] An air purification device for cleanrooms, comprising:

[0029] A purification shell 1 has an air inlet pipe 2 and an air outlet pipe 3 symmetrically connected to it, located on the left and right sides respectively. A motor 4 is installed on one side of the purification shell 1, and a disc 5 located inside the purification shell 1 is fixed to the output shaft of the motor 4. The disc 5 overlaps with the inner wall of the purification shell 1. When the motor 4 performs work, its output shaft drives the disc 5 to rotate. An annular filter cartridge 6 is installed on one side of the disc 5, and the axial end face of the annular filter cartridge 6 overlaps with the inner wall of the purification shell 1. When the disc 5 rotates, it drives the annular filter cartridge 6 to rotate synchronously. There is an annular gap between the annular filter cartridge 6 and the purification shell 1. The inner wall of the purification shell 1 is provided with two sealing blocks 7 whose ends overlap with the outer wall of the annular filter cartridge 6. Preferably, combined with Figure 2 , Figure 6 and Figure 7 As shown, one sealing block 7 is located in the upper left corner corresponding to the air inlet pipe 2, and the other sealing block 7 is located in the lower right corner corresponding to the exhaust pipe 3. Since there is an annular gap between the annular filter cartridge 6 and the purification shell 1, when the airflow flows from the air inlet pipe 2 into the purification shell 1, the airflow will pass through the annular filter cartridge 6 and flow out from the exhaust pipe 3. However, solid impurities (dust) will be intercepted on the surface of the annular filter cartridge 6. At this time, due to the influence of the annular gap, when the annular filter cartridge 6 rotates, the dust will not be scraped by the inner wall of the purification shell 1, and the dust will not fly around. By sealing the two sealing blocks 7, the airflow can only pass through the annular filter cartridge 6 to enter the exhaust pipe 3, so as to ensure effective interception of dust.

[0030] The dust removal mechanism 8 includes a water storage shell 801 connected to the purification shell 1. The water storage shell 801 is located directly below the purification shell 1 and is used to store clean water. Preferably, the water storage shell 801 is connected to a water inlet pipe and a water outlet pipe for easy water addition or drainage. To make the design more efficient, the water level in the water storage shell 801 is lower than the bottom of the annular filter cartridge 6, so that the outer surface of the annular filter cartridge 6 will not come into contact with water when it rotates. The water storage shell 801 is connected to a conveying pipe 802. The free end of component 2 extends into the purification shell 1 and is connected to a water spray component 803. Preferably, the water spray component 803 is located inside the annular filter cartridge 6. A water pump 804 installed on the purification shell 1 is connected to the conveying pipe 802. When intercepting dust, the dust adheres to the surface of the annular filter cartridge 6. The motor 4 drives the annular filter cartridge 6 to rotate, so that the side with the dust attached is rotated directly above the water storage shell 801. The water pump 804 performs work, which transports water from the water storage shell 801 through the conveying pipe 802. Water is sprayed downwards from the annular filter cartridge 6 into the water spraying component 803. The water sprays directly onto the lower section of the annular filter cartridge 6 (the part where dust is attached), flushing the dust into the water storage shell 801 (dust is trapped on the outer surface of the annular filter cartridge 6; water washes it away from the inside). As the annular filter cartridge 6 continues to rotate, the trapped dust is flushed into the water storage shell 801, forming a water circulation system to clean the dust trapped in the annular filter cartridge 6. The section of the annular filter cartridge 6 that has been cleaned by water rotates back to the air inlet pipe 2, where it filters and traps dust again. This prevents the annular filter cartridge 6 from becoming clogged during prolonged use, ensuring airflow while maintaining effective air filtration. The trapped dust is then easily removed by simply opening the drain pipe.

[0031] The adsorption and purification element 9 is set on the purification shell 1 and located inside the annular filter cartridge 6. Since the dust is intercepted outside the annular filter cartridge 6, only the filtered gas (referring to dust without solid impurities after dust removal) can pass through the annular filter cartridge 6. Therefore, the adsorption and purification element 9 is not affected by dust and other impurities, thus effectively adsorbing and purifying the gas.

[0032] In this design, the annular filter cartridge 6 is rotatably installed inside the purification housing 1. As the annular filter cartridge 6 rotates, it filters and intercepts dust in the air. With the continuous rotation of the annular filter cartridge 6, water is sprayed from inside the annular filter cartridge 6 outward, washing the dust adhering to the surface of the annular filter cartridge 6 into the water storage housing 801. This allows the annular filter cartridge 6 to be quickly cleaned while filtering and intercepting dust. After being cleaned, it rotates again to intercept dust in the air. While ensuring the filtration and interception of airflow, it facilitates airflow and makes it less prone to clogging. At the same time, opening the drain pipe facilitates the cleaning of wastewater and dust, thereby improving practicality.

[0033] like Figure 4 As shown, in this embodiment, the water spray component 803 includes a main pipe 8031 ​​connected to the conveying pipe 802. Several secondary pipes 8032 are arrayed along the length of the main pipe 8031, and several nozzles 8033 are arrayed along the length of the secondary pipes 8032. Water flows from the conveying pipe 802 into the main pipe 8031, then splits into the several secondary pipes 8032, and finally sprays downward from the several nozzles 8033, resulting in a wide spray range and uniform spraying. This effectively cleans the dust intercepted on the surface of the annular filter cartridge 6, thereby improving its practicality.

[0034] like Figure 3 As shown, in this embodiment, a mesh cover 10 covering the connection port of the delivery pipe 802 is provided inside the water storage shell 801. Since the water flow forms a water cycle, the mesh cover 10 can intercept dust in the water and prevent dust from entering the water pump 804, thus protecting the water pump 804. At the same time, it can also prevent dust from entering the annular filter cartridge 6 with the water flow, thereby improving practicality.

[0035] like Figure 2 As shown, in this embodiment, two partitions 11 are provided on the inner wall of the purification shell 1 on the side away from the motor 4. Both ends of the partitions 11 are in contact with and overlap the inner wall of the annular filter cylinder 6. Preferably, the end of the partition 11 overlaps with the disc 5. The flow channel formed between the two partitions 11 is aligned with the air inlet pipe 2 and the air outlet pipe 3. The flow channel formed by the two partitions 11 facilitates the guidance of airflow, so that after the airflow passes through the annular filter cylinder 6, it can flow smoothly into the air outlet pipe 3, thereby improving practicality. Preferably, the water spray component 803 is located below the lower partition 11.

[0036] like Figure 5 and Figure 6As shown, in this embodiment, the adsorption and purification component 9 includes a mesh bag 901 disposed on the inner wall of the purification shell 1. The mesh bag 901 is located between two partitions 11 and contains activated carbon 902. Preferably, the activated carbon 902 can be activated carbon adsorption particles or activated carbon adsorption plates. After the airflow passes through the dust filter, it will flow between the two partitions 11. The airflow will pass through the mesh bag 901 and the activated carbon 902. The activated carbon 902 adsorbs and purifies the dust, further improving the purification effect.

[0037] like Figure 3 and Figure 5 As shown in this embodiment, a high-flux pulsed xenon lamp 12 is installed on the inner wall of the purification shell 1. The high-flux pulsed xenon lamp 12 is located between two partitions 11. The high-flux pulsed xenon lamp 12 is a novel cold sterilization technology. This technology releases the electrical energy stored in the ultra-large capacity capacitor instantaneously. Through high-voltage ionization of the high-purity xenon gas in the lamp tube, it generates a pulse of intense light with a duration of only 10-100ms and an energy of up to 2J / cm². This can effectively destroy various pathogens to achieve sterilization and disinfection. When the airflow flows between the two partitions 11, it will pass through the high-flux pulsed xenon lamp 12. Under normal circumstances, a good sterilization effect can be achieved through several flashes, which is a fraction of a second, thereby further improving the air purification effect.

[0038] like Figure 3 As shown, in this embodiment, a through groove 13 is provided on one side of the purification shell 1, and a cover plate 14 is provided on the purification shell 1 to block the through groove 13. The mesh bag 901 and the high-flux pulse xenon lamp 12 are both set on the cover plate 14. When the activated carbon 902 is used for a period of time, it will become saturated with adsorption. Therefore, it needs to be replaced regularly. By providing a cover plate 14 to cover the through groove 13, the mesh bag 901 and the high-flux pulse xenon lamp 12 are set on the cover plate 14, which not only facilitates the replacement of the activated carbon 902, but also facilitates the inspection and maintenance of the high-flux pulse xenon lamp 12.

[0039] like Figure 7 As shown, in this embodiment, the inner wall of the water storage shell 801 is provided with a support plate 15, and a plurality of bristles 16 with ends overlapping the outer wall of the annular filter cylinder 6 are arranged in an array on the support plate 15. Since the surface of the annular filter cylinder 6 has many filter holes, a water film is easily generated in the filter holes when water is sprayed. Through the support plate 15 and the bristles 16, when the annular filter cylinder 6 rotates, the bristles 16 scrape the surface of the annular filter cylinder 6, which not only improves the cleaning effect of dust, but also scrapes the annular filter cylinder 6, punctures the water film, and facilitates the normal flow of air.

[0040] The working process of this utility model is as follows: When purifying the airflow, the motor 4 drives the annular filter cartridge 6 to rotate, and the water pump 804 creates a water spray circulation. The airflow flows through the air inlet pipe 2, passes through the annular filter cartridge 6, and is discharged from the exhaust pipe 3. The annular filter cartridge 6 intercepts dust and impurities in the air. The rotation of the annular filter cartridge 6 causes the side with dust to rotate directly above the water storage shell 801. The water spraying component 803 sprays water downward from inside the annular filter cartridge 6. When the water sprays downward, it sprays the section of the annular filter cartridge 6 located directly below (the spraying part is exactly the part with dust), which can wash the dust into the water storage shell 801 (the dust is intercepted in the annular filter cartridge 6). On the outer side, water washes from the inside out, effectively cleaning the intercepted dust. The section of the annular filter cartridge 6 that has been cleaned by water rotates back to the air inlet pipe 2 to intercept and filter dust again. This prevents the annular filter cartridge 6 from becoming clogged during long-term use, ensuring airflow while maintaining effective air filtration. Meanwhile, the intercepted dust is trapped inside the water storage shell 801. When cleaning the dust, simply open the drain pipe of the water storage shell 801 to quickly remove the intercepted dust. At the same time, the dust will not affect the adsorption and purification component 9 and the high-flux pulse xenon lamp 12, which can further adsorb and purify the air, thereby improving the air purification effect.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
