Description
Technical Field
The utility model relates to a dust removal filtration technology especially relates to a section of thick bamboo is strained with easy clean plastics sintering to dust remover.
Background
The plastic sintered filter element, also called sintered plate and sintered plate, has the characteristics of extremely high filtering efficiency, strong moisture resistance, super long service life and the like, and is gradually used on dust removing equipment. However, the plastic sintered plate can not directly replace the filter bag of the prior cloth bag dust remover in China, so that after the filter element technology is digested and absorbed, a cylindrical structure called as a plastic sintered filter cylinder is correspondingly produced, the plastic sintered filter cylinder has the filtering performance completely consistent with that of the filter element of the plastic sintered plate, and the installation size compatible with the prior dust removing filter bag is realized, so that the prior cloth bag dust remover can be upgraded and reformed at the minimum cost. Because the ratio of the volume of the inner cavity of the plastic sintering filter cylinder to the filter area is larger than that of the plastic sintering plate, the volume of the dust remover using the plastic sintering filter cylinder is larger than that of the dust remover using the plastic sintering plate on the premise of the same filter area. Meanwhile, when the ash is removed by blowback, the compressed air needs to fill the inner cavity first and then forms effective pressure on the inner surface of the filter material, so that the clean air penetrates through the micropores and peels off dust on the outer surface of the filter material, and more compressed air consumption is caused. The Chinese utility model with the publication number of CN206934967U discloses a sintered filter cartridge with a reinforced lining, which comprises a filter element, a seal tail and a seal head, wherein the cross section of the filter element is in a quincunx shape, a cylindrical lining is arranged in the filter element, the lining and the filter element are in interference fit, and a plurality of air holes are formed in the surface of the lining; the length of the lining is greater than that of the filter element, mounting threads are arranged at two ends of the lining, and the seal tail and the seal head are mounted at two ends of the filter element through the additional threads and the seal ring; the utility model discloses a through the filter core of plum blossom shape the convenience of filter core dismouting has been strengthened, still need relapse clean many times, and does not improve the big problem of compressed air consumption.
