Dust recovery device and recovery method of hygiene products

Abstract

The invention provides a dust recovery device and a recovery method of hygiene products. The dust recovery device of hygiene products comprises a dust recovery device, wherein the dust recovery device comprises a left box body, a middle box body and a right box body which are arrayed in an assembly way; air outlets of air suction fans are communicated with the left box body; a dust collection device is arranged in the middle box body, the dust collection end of the dust collection device stretches into the right box body and extends to the position between two adjacent filtering devices, a dust collection fan is arranged outside the middle box body, and one end of the dust collection fan is connected with the dust collection device, and the other end of the dust collection fan is communicated with a dust box; and multiple layers of filtering devices are horizontally arranged in the right box body in a sleeving way, air outlets are arranged on right sides of the filtering devices, and the air outlets are used for being communicated with the inner parts of the filtering devices and the outside. According to the invention, as the multiple layers of filtering devices are adopted, the filtering area is large; the internal and external pressure difference of the dust recovery device is small, so that villi in the dust are not damaged easily; and the recovered dust is collected rather than being used directly, so that the impurities in the dust is prevented from influencing the subsequent product quality.

Description

technical field [0001] The invention relates to the field of dust recovery devices, in particular to a dust recovery device and a recovery method on a hygiene product production line. Background technique [0002] At present, the sanitary products production line produces a large amount of dust when producing sanitary napkins, baby diapers, incontinence pants, and baby training pants. The dust also contains a lot of fluff. If the dust is not recycled, it will not only cause waste of resources and high manufacturing costs. , and environmental pollution directly affects the health of operating workers. [0003] In the prior art, the Chinese patent whose authorized notification number is CN 101768897 B discloses a sanitary product production line with a fluff pulp recycling device and a recovery method, which includes a sanitary product production line, a demoulding fan and a conveying fan in the sanitary product production line 1. The air outlets of the dust suction fan are r...

AI Technical Summary

Problems solved by technology

[0004] Although the comparison document realizes the recycling of fluff pulp and reduces the dust pollution on the production site, but because the fluff recovered by this system is mixed with impurities and dust, if it enters the forming box of the production line directly through the pipeline, the sanitation will be greatly reduced. The quality of the product is high, and the effective dust removal area of ​​this system is small, and the recycling rate of fluff pulp is low
