Hot air conveying device of non-woven fabric production equipment

Abstract

The invention discloses a hot air conveying device of non-woven fabric production equipment, which comprises a purification box body, a rotating shaft is movably connected to the middle position of the top of the purification box body, the rotating shaft extends into an inner cavity of the purification box body, a filter screen is fixedly connected to the bottom of the rotating shaft, a nano-silver ion layer is arranged on the inner wall of the filter screen. an activated carbon layer is arranged on the inner wall of the nano-silver ion layer, brush plates are fixedly connected to the left side and the right side, opposite to the filter screen, of the inner wall of the purification box body, a rotating disc is fixedly connected to the top of the rotating shaft, and a steam driving mechanism is fixedly installed on the left side wall of the purification box body. When the filter screen rotates, a rotary drum can be driven to continuously rotate relative to the inner wall of a dust collection shell, and when the rotary drum rotates, a scraper blade can be driven to synchronously rotate, so that impurities swept to the upper surface of the dust collection shell are continuously scraped away and fall into an inner cavity of the dust collection shell through a groove hole, dust can be conveniently and uniformly collected, and dust in the inner cavity of the dust collection shell can be conveniently and timely cleaned through a dust outlet.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric processing, in particular to a hot air conveying device of non-woven fabric production equipment. Background technique [0002] Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are mostly used as The raw material is produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling, and the non-woven fabric is equipped with a hot air conveying device in the production process, and the hot air is used to ensure the stability of the ambient temperature during the melt-blown spinning stage , to ensure the quality of spinning. [0003] However, the existing hot air conveying device has poor cleaning effect on impurities in the air. After long...

Problems solved by technology

[0003] However, the existing hot air conveying device has a poor cleaning effect on impurities in the air. After long-term use, the filter screen will stick to a large amount of impurities, which will lead to poor filtering effect, and it is inconvenient to collect scattered dust in a centralized manner, and the degree of automation is low.
