Description

Technical Field

[0001] This utility model relates to the field of air self-cleaning technology, specifically to a self-cleaning sterilization and purification device for circulating air in a closed environment. Background Technology

[0002] In many enclosed environments, such as hospital operating rooms, laboratories, electronic chip manufacturing workshops, the interiors of aerospace vehicles, and submarines, extremely high requirements are placed on air quality. These places need to strictly control pollutants such as particulate matter, microorganisms, and harmful gases in the air to ensure the health of personnel, the normal operation of equipment, and product quality. For example, hospital operating rooms require a sterile air environment to prevent surgical infections; electronic chip manufacturing workshops require extremely low concentrations of particulate matter in the air, otherwise it may affect the performance and yield of chips.

[0003] To meet the stringent air quality requirements of enclosed environments, self-cleaning sterilization and purification devices have emerged. These devices not only efficiently purify the air but also possess a self-cleaning function, reducing the frequency and cost of manual maintenance and improving the reliability and stability of the equipment.

[0004] A search revealed Chinese patent document CN215507293U, which discloses a self-cleaning air purification and sterilization device. During operation, air enters from the fan located inside the first mounting side plate and exits from the second mounting side plate. When dust in the air passes through the negative electrode needle assembly, the dust is adsorbed onto the dust collection belt by the action of electric and magnetic fields. The air purification device is located below the cleaning tank of an ultrasonic cleaning device.

[0005] The aforementioned patent documents disclose that the dust collection belt can be cleaned by ultrasonic cleaning. However, in actual use, the dust collection belt cannot be used immediately after it gets wet and needs to be dried before it can be used. The long downtime for cleaning and drying will affect the efficiency of the device. Therefore, how to clean the dust collection belt without stopping the machine is an urgent problem to be solved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model discloses a self-cleaning sterilization and purification device for circulating air in a closed environment, including a circulation device 1 and a filter mechanism symmetrically arranged at both ends inside the circulation device 1. The filter mechanism includes an activated carbon device 2, a dust collection belt 4, and an electrode device 6. The activated carbon device 2 and the dust collection belt 4 sequentially filter, sterilize, and purify the air. A cleaning device is located below the filter mechanism, with the lower end of the dust collection belt 4 extending into the cleaning device. The cleaning device includes an installation box 8, a cleaning box 9, a scraper 11, a scraper 2 13, and a water-absorbing roller 14. The scraper 11 is located on one side of the lower end of the dust collection belt 4 and is used to scrape off the dust adhering to the dust collection belt 4. The dust collection belt 4 is close to the scraper... Scraper 13 is symmetrically arranged on the inner and outer sides of one side of plate 11 to scrape the water droplets attached to the dust collection belt 4. The water absorption roller 14 is arranged above scraper 13 to absorb the water droplets attached to the dust collection belt 4. The filter device 17 is arranged between the two cleaning devices and is connected to the two cleaning devices through the conveying mechanism. The mounting box 8 is installed at the bottom of the circulation device 1 by screws. The cleaning box 9 is installed in the mounting box 8 through the limiting mechanism. The depth of the mounting box 8 is greater than the depth of the cleaning box 9. The cleaning box 9 is used to hold the cleaning liquid. The bottom of the cleaning box 9 is equipped with an ultrasonic device 10 for ultrasonic cleaning of the dust collection belt 4 immersed in the cleaning liquid.

[0027] Specifically, the activated carbon device 2 and the dust collection belt 4 are arranged sequentially from the inside to the outside. Ventilation plates 3 are respectively arranged on both sides of the dust collection belt 4, and the electrode device 6 is located inside the dust collection belt 4. The upper and lower ends of the inner side of the dust collection belt 4 are respectively connected to the transmission rollers 7, and a drive motor 5 is installed at one end of the upper transmission roller 7.

[0028] In this embodiment, the drive motor 5 is mounted on the circulation device 1 by screws, which drives the upper transmission roller 7 to rotate. The dust collection belt 4 is transported by the arrangement of the dust collection belt 4 and the lower transmission roller 7. The dust collection belt 4 is immersed in the cleaning liquid for ultrasonic cleaning. Air enters from the circulation device 1 and the ventilation plate 3 on one side between the two ventilation plates 3. The electrode device 6 operates, causing dust to be adsorbed on the dust collection belt 4. Then the air passes through the inner ventilation plate 3, passes through the activated carbon device 2 for filtration and sterilization, and enters the circulation device 1 for subsequent operations and output.

[0029] Specifically, a mounting bracket 12 is fixed on the scraper 11, and the scraper 2 13 on the outside of the dust collection belt 4 and the water suction roller 14 are both mounted on the mounting bracket 12. The mounting bracket 12 is installed inside the mounting box 8 by screws, and the scraper 2 13 and the water suction roller 14 on the inside of the dust collection belt 4 are both installed between the two side walls of the mounting box 8.

[0030] In this embodiment, during the conveying process of the dust collection belt 4, it is first immersed in cleaning liquid and then cleaned by ultrasonic waves. After passing through scraper 11, scraper 11 cleans the belt, removing the dust that was not removed by the ultrasonic waves. The dust collection belt 4 continues to be conveyed and passes through two scraper 2 13. The two scraper 2 13 scrape off the water droplets attached to the dust collection belt 4, and the scraped water droplets fall into the cleaning box 9. The dust collection belt 4 continues to be conveyed and passes through two water absorption rollers 14, which absorb the residual water stains on the dust collection belt 4. This achieves the purpose of dehydration and drying of the dust collection belt 4 after cleaning, so that the device does not need to be stopped and avoids affecting the efficiency of the device.

[0031] Specifically, the bottom of the cleaning box 9 is provided with conveying mechanisms at both ends. The conveying mechanism includes a connector 15, a hose 16, and a solenoid valve 18. The connector 15 is fixed to the bottom of the cleaning box 9. One end of the hose 16 is threaded to the connector 15. The hose 16 passes through the bottom of the mounting box 8. The other end of the hose 16 is installed on the filter device 17. The solenoid valve 18 is located on the hose 16. The filter device 17 is installed at the bottom of the circulation device 1 by screws.

[0032] In this embodiment, after the cleaning solution has been used for a period of time, the filter device 17 can be operated and the solenoid valve 18 can be opened, so that the cleaning solution in the cleaning tank 9 can enter the filter device 17 through the connector 15 and the hose 16 for filtration, and then be transported back to the cleaning tank 9 for continued use, thereby extending the service life of the cleaning solution and reducing the number of times the cleaning solution can be replaced. For example, the replacement time can be extended from once every 2-3 days to once every 7-10 days.

[0033] Specifically, the cleaning box 9 includes an upper edge plate and a box body. The upper edge plate is located at the top of the box body. Threaded posts are fixed at the four corners of the bottom of the upper edge plate. Nuts are fitted on the outside of the threaded posts. A limiting mechanism is located below the upper edge plate. The limiting mechanism includes a limiting frame 20 and a connecting post 21. The limiting frame 20 includes a top plate and an insert post. Multiple insert posts are fixed at the bottom of the top plate. The insert posts are inserted into the connecting posts 21. The connecting posts 21 are fixed at the bottom of the inner side of the mounting box 8. Rubber pads 19 are provided above and below the top plate. The upper rubber pad 19 is located between the top plate and the upper edge plate. The threaded posts pass through the two rubber pads 19 and the top plate. Nuts are located below the lower rubber pad 19.

[0034] In this embodiment, the upper edge plate, threaded column and box body are all integral structures, the top plate and the insertion column are integral structures, the rubber pad 19 is provided to provide shock absorption and buffer for the cleaning box 9 when the ultrasonic device 10 is operating, and the limit frame 20 and the connecting column 21 are provided to limit the installation of the cleaning box 9.

[0035] The working principle and usage process of this utility model are as follows: During use, the drive motor 5 drives the upper transmission roller 7 to rotate. Through the arrangement of the dust collection belt 4 and the lower transmission roller 7, the dust collection belt 4 is conveyed and continuously immersed in the cleaning solution. The ultrasonic device 10 operates, performing ultrasonic cleaning on the portion of the dust collection belt 4 immersed in the cleaning solution during its conveying process. Then, it passes through the scraper 11, where the scraper 11 scrapes away any dust that was not removed by the ultrasonic waves. The dust collection belt 4 then continues conveying. After passing through two scrapers 13, the water droplets attached to the dust collection belt 4 are scraped off and fall into the cleaning tank 9. The dust collection belt 4 continues to be conveyed and passes through two water suction rollers 14 to absorb the residual water stains on the dust collection belt 4 and remove water and dry it. After the cleaning liquid has been used for a period of time, it can be filtered by the operation of the filter device 17. The solenoid valve 18 is opened, so that the cleaning liquid in the cleaning tank 9 enters the filter device 17 through the connector 15 and the hose 16 for filtration, and then is sent back to the cleaning tank 9 for continued use.
