Background

With the rapid development of the printing packaging industry, the demand on printing raw material ink is more and more, and the ink comprises polymer resin, monomer diluent, photoinitiator, pigment, auxiliary agent, filler and the like. Dust generated in the production process of the ink pollutes the atmosphere and harms the health of human beings. Dust that escapes the atmosphere often contains many toxic components such as chromium, manganese, cadmium, lead, mercury, arsenic, and the like. When the human body inhales dust, the particles smaller than 5 μm are easy to penetrate into the lung, causing toxic pneumonia or silicosis, and sometimes causing lung cancer. Once dissolved, the contaminants deposited in the lungs directly invade the blood and cause blood poisoning, and the undissolved contaminants may also be absorbed by the cells, resulting in destruction of the cellular structure. In addition, dust can also stain buildings, causing valuable ancient buildings to corrode. The dust falling on the leaf surface of the plant can block photosynthesis and inhibit the growth of the plant. Secondly, dust has a certain energy as well as other substances. The surface energy of the dust is also increased due to the small particle size and large surface area of the dust. One coal with the weight of 1g has the surface area of only 5-6 c square meters, while 1g of coal dust can float, and the surface area can reach 2 square meters. The dust is mixed with air to form combustible mixed gas, if the dust meets open fire or high-temperature objects, the dust is very easy to catch fire, the combustion process is finished in a tilting room, a large amount of heat energy is released, the combustion gas is suddenly raised, the volume is violently expanded, and high expansion pressure is formed, which indicates that the explosion is easily caused by the overhigh dust content in the air. In the existing exhaust filtering device, most of products are packed by filter cloth on a flat opening or are filtered without an external protective sleeve, so that the existing filter element has the defects of insufficient filtering area and easy damage. Therefore, further improvements are desired.
