Air filter unit based on filter screen vibration

Abstract

The invention discloses an air filter unit based on filter screen vibration. The air filter unit comprises an air inlet layer, an air exhaust layer and a lifting control unit (11), wherein the air inlet layer comprises a first air inlet opening (1), an air filter chamber (2) provided with a filter screen (10), an air inlet chamber (3) and a first air exhaust opening (4), which are communicated insequence; the air exhaust layer comprises a second air inlet opening (5), an air exhaust chamber (6), a filter screen blowback chamber (7) and a second exhaust opening (8), which are communicated in sequence; a baffle plate (9) is arranged between the air inlet layer and the air exhaust layer; the baffle plate (9) is provided with a gap cooperating with the filter screen; the lifting control unit(11) is connected with the filter screen (10) and controls the switching, between the air filter chamber (2) and the filter screen blowback chamber (7), of the filter screen (10); a knocking vibrationunit cooperating with the filter screen (10) is also arranged in the filter screen blowback chamber (7). According to the air filter unit, the filter screen is cleaned in the filter screen blowback chamber; the filter screen is knocked by utilizing the knocking vibration unit to vibrate the filter screen and the cleaning efficiency of the filter screen is improved.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to an air filtration device based on filter screen vibration. Background technique [0002] Air pollution refers to the phenomenon that certain substances enter the atmosphere due to human activities or natural processes, present a sufficient concentration and reach a sufficient time, and thus endanger human comfort, health and welfare or the environment; as my country's industrial Air pollution has become an urgent problem to be solved. [0003] There are many types of air pollutants, and their forms may be solid particles, liquid droplets or gases, or a mixture of these forms; for now, the air pollutants caused by solid particles Pollution, there are many treatment methods, such as electrostatic dust removal, negative oxygen ion technology and filter screen filtration; however, electrostatic dust removal and negative oxygen ion technology will generate additional ozone, which will ca...

Problems solved by technology

[0003] There are many types of air pollutants, and their forms may be solid particles, liquid droplets or gases, or a mixture of these forms; for now, the air pollutants caused by solid particles Pollution, there are many treatment methods, such as electrostatic dust removal, negative oxygen ion technology and filter screen filtration; however, electrostatic dust removal and negative oxygen ion technology will generate additional ozone, which will cause new pollution, and their dust removal effect is much smaller than that of media ( At the same time, the electrostatic precipitator electrode will also be required to be cleaned every once in a while, and it is extremely troublesome to clean the electrostatic precipitator electrode with water; while the air filter device produced by ordinary manufacturers using the filter mesh filter method, in order to ensure the air filtration capacity , it is generally required to replace the filter screen every 3 to 6 months, which brings great inconvenience to the use of the air filter device and is not conducive to reducing costs.

[0004] In order to increase the service life of the filter screen, some common methods are to install a reverse exhaust fan in the air inlet channel of the air filter device. The solid particles are blown out to the outside, but installing a reverse blower in the air intake channel greatly increases the complexity of the air filter device; the filter cleaning is carried out in the air intake channel, which is easy to cause pollution to the air intake channel; at the same time, only the reverse blower is used way, the filter cleaning effect is not obvious
