Description

Technical Field

[0001] This utility model relates to the field of air filtration device technology, specifically to an environmentally friendly air filtration device. Background Technology

[0002] Environmental engineering refers to projects specifically undertaken for environmental protection. Air filtration devices are equipment that capture dust from a gas-solid two-phase flow and purify the gas through the action of porous filter materials. They purify air with low dust content before delivering it indoors to ensure the process requirements of clean rooms and the air cleanliness of general air-conditioned rooms. Air filtration devices are designed to obtain clean air that meets standards. General ventilation filters capture and adsorb dust particles of different sizes in the air, improving air quality. Chemical filters, in addition to adsorbing dust, can also adsorb odors and are commonly used in biopharmaceuticals, hospitals, airport terminals, and residential environments.

[0003] Patent No. CN202322445457.0 discloses an environmental protection engineering air filtration device, including a filter cartridge. The top of the filter cartridge is detachably connected to a top cover. A filter assembly is detachably connected to the lower surface of the top cover. The filter assembly includes a dust filter cartridge and an activated carbon adsorption cartridge. The activated carbon adsorption cartridge is detachably connected to the outer wall of the dust filter cartridge. A servo motor is embedded in the center of the top cover, and the power output end of the servo motor passes through the top cover and extends into the interior of the dust filter cartridge. The power output end of the servo motor is fixedly connected to a transmission rod.

[0004] While the aforementioned patent allows for quick cleaning of the filter mechanism without requiring manual removal of the filter plates, its simple structure reduces workload and effectively filters air, improving air cleanliness and providing a comfortable environment. However, during actual cleaning, dust cleaned by the brush floats inside the filter cartridge. The continuous airflow from the fan causes this dust to re-adhere to the inner wall of the filter cartridge, only falling into the collection hopper by gravity when the fan stops. This prevents the device from effectively cleaning the inner wall of the filter cartridge during operation, resulting in poor cleaning performance. Therefore, an environmentally friendly air filtration device is urgently needed to solve these problems. Utility Model Content

[0016] By adopting the above technical solution, the spray pipe drives the brush to rotate and clean the dust on the inner wall of the filter cartridge. During the cleaning process, the atomizing nozzle sprays water atomized, which can play the role of atomizing and reducing dust, thus preventing dust from re-adhering to the inner wall of the filter cartridge under the action of airflow, and ensuring the cleaning effect of the device.

[0017] Furthermore, the extraction pipe is fixedly connected to the water tank and the universal joint, and the metering pump is fixed to the extraction pipe by bolts.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] To address the problem in existing environmental air filtration equipment where dust cleaned by the brushes floats inside the filter cartridge during self-cleaning, only to be re-adheded to the inner wall by the continuous airflow from the fan, and finally falls into the collection hopper by gravity when the fan stops, resulting in poor cleaning performance, this invention addresses this issue by incorporating a gear ring, gears, a spray pipe, a universal joint, and atomizing nozzles. During cleaning, a drive motor rotates the gear ring via the gears, which in turn rotates the brushes on the spray pipe to clean the dust from the inner wall of the filter cartridge. Simultaneously, the atomizing nozzles spray water to atomize and suppress dust, preventing it from re-adhere to the filter cartridge under airflow and ensuring effective cleaning.
