Problems solved by technology

[0004] The melt needs to be kept at a certain temperature during transmission, and most of the existing filters cannot maintain the temperature of the melt. Too much temperature drop during the melt transmission will easily cause the melt to solidify, and the filtering effect of the existing filters is not good. Well, there will still be more impurities in the melt

Abstract

The invention discloses a spiral filtering device for producing a melt-blown non-woven fabric special material, which comprises a shell and a barrel arranged in the shell, and further comprises a filtering part arranged in the barrel and used for filtering and removing impurities from a melt, and a heat preservation part arranged on the outer side of the barrel and used for heating the melt. According to the invention, the barrel is arranged in the shell, a fixing ring is arranged on the barrel, a filter screen is arranged on the fixing ring, a filter plate is arranged on the inner side of the barrel, a melt enters a filter and then sequentially passes through the filter screen and the filter plate, the filter screen is used for removing granular impurities, and the filter plate of a spiral structure is used for adsorbing small-particle impurities. Therefore, the filtering device improves the filtering performance of the existing filter and is beneficial to reducing residual impurities in the melt.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a spiral filter device for producing special materials for melt-blown non-woven fabrics. Background technique [0002] Melt blown cloth is the core material of the mask. The melt blown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good wrinkle resistance. The ultrafine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt blown cloth has good filterability, shielding, heat insulation and oil absorption. It can be used in air and liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, oil absorption materials and wiping cloths and other fields. [0003] The production process of meltblown cloth is melt preparation, filtration, metering, extrusion of melt ...
