Description
Technical Field
The utility model belongs to the technical field of hot air non-woven fabric production auxiliary equipment, and particularly relates to a dust removing device for hot air fabric production.
Background
The hot air cloth, namely the hot air non-woven fabric, belongs to one of the hot air bonded non-woven fabrics, and is the non-woven fabric which is produced by the way that after fibers are carded, hot air on a drying device penetrates through a fiber web to be heated so as to be bonded.
In the production process of the hot air non-woven fabric, a large amount of sundries such as dust and the like can appear, and a large amount of wool fibers can appear on the surface of the non-woven fabric due to the special property of the non-woven fabric material. Therefore, before the hot air non-woven fabric is rolled, the wool fibers on the surface of the non-woven fabric need to be treated, so that sundries are prevented from being rolled in the cloth roll.
The existing dust removing device adopts a blowing or beating mode to remove the wool fibers on the surface of the non-woven fabric, then utilizes a fan to pump away the air flow with the wool fibers, and utilizes a filter screen plate or a cloth bag dust remover to filter the wool fibers in the air flow, thereby the whole dust removing process is completed. However, due to the specificity of the non-woven fabric, the impurity mixed with the non-woven fabric contains more wool fibers, which easily causes the blockage of the filter screen plate or the cloth bag dust collector. When the filter screen plate is cleaned later, the filter screen plate needs to be pulled out of the dust collection box for cleaning, and the process is complicated. The bag-type dust collector is cleaned by adopting a back blowing method, but the wool fibers are tiny and are easy to adhere to the surface of the dust collection bag, so that the subsequent dust collection efficiency is affected. Therefore, the dust collector for hot air cloth production is provided with good filtering effect and convenient cleaning.
