Automatic cleaning device of air filtering medium

Abstract

The invention relates to an automatic cleaning device of an air filtering medium. The automatic cleaning device comprises a box body, wherein the left side wall and the right side wall of the box body are provided with an air inlet and an air outlet, respectively; the box body is internally provided with a high-pressure coil plate and an active carbon plate; a water channel is arranged at the bottom part in the box body; the left side wall of the water channel is provided with a water pump which is provided with a guide pipe; the other end of the guide pipe is provided with a spraying nozzle; a rotating mechanism is arranged above the water channel in the box body and is formed by an upper rotating shaft, a lower rotating shaft and ring-shaped filtering cloth. The automatic cleaning device is simple in structure and wide in applicability, can be used in regions such as residential buildings or chemical industries, is convenient to install, can be directly arranged at an air opening of multiple equipment such as an exhaust fan or a range hood, and has the advantages that the filtering cloth does not need to be replaced, and as the filtering cloth cannot deviate, the filtering cloth is prevented from being clamped in the rotating shaft; the internal structure of the device guarantees no ventilation, and the high-pressure coil plate, the ring-shaped filtering cloth and the active carbon plate are matched with one another, so that the efficiency of purifying and filtering oil smoke is obvious.

Description

[0001] technical field [0002] The invention belongs to an oil fume purification medium device, in particular to an air filter medium automatic cleaning device with simple structure, obvious purification and filtration effect and wide applicability. Background technique [0003] PM2.5 refers to particulate matter with an aerodynamic equivalent diameter less than or equal to 2.5 microns in the ambient air, also known as fine particulate matter, which can be suspended in the air for a long time. The higher the content in the air, the more serious the air pollution. At present, PM2.5 is seriously exceeded in some areas of our country. One of the reasons for this phenomenon is the oily fumes discharged from various kitchens. People use air purification equipment to filter the air. The filter cloth or filter screen inside the traditional air evolution equipment It must be cleaned or replaced after long-term use, otherwise the dirt in the oil fume will block the filter cloth or f...

[0003] PM2.5 refers to particulate matter with an aerodynamic equivalent diameter of less than or equal to 2.5 microns in the ambient air, also known as fine particulate matter, which can be suspended in the air for a long time. The higher the content in the air, the more serious the air pollution. At present, PM2.5 exceeds the standard seriously in some areas of our country. One of the reasons for this phenomenon is the fumes discharged from various kitchens. People use air purification equipment to filter the air. The filter cloth or filter screen inside the traditional air evolution equipment It must be cleaned or replaced after long-term use, otherwise the dirt in the oil fume will block the filter cloth or filter screen and reduce the filtering effect of oil fume. Now there are some purification equipment on the market that automatically cleans the filter cloth or filter screen. The following problems: First, the filter cloth inside the equipment is easy to deviate during the movement, which will cause part of the dirt to fail to pass through the filter cloth, resulting in a reduction in the effect of filtration and purification. In addition, the deflection of the filter cloth may also get stuck in the shaft , damage the machine, second, the ventilation inside the equipment will also make part of the dirt not pass through the filter cloth, but will be sent out with the airflow from the gap, thereby reducing the effect of purification and filtration. Third, due to the hydrogen sulfide and ammonia contained in the oil fume and other substances, especially in chemical plants, there are a lot of harmful gases mixed in the oil fume. Although the traditional oil fume purification equipment can purify the oil fume to a certain extent, it cannot remove these substances, and cannot effectively remove the peculiar smell
