A kind of air filter cotton preparation raw material mixing pretreatment process

Abstract

The invention relates to an air filter cotton preparation raw material mixing pretreatment process. The filter cotton preparation raw material mixing pretreatment process adopts a following pretreatment machine which comprises a shell and a partition plate arranged in the shell; the partition plate divides the shell into a stirring cavity and an opening cavity; feeding devices are symmetrically arranged on the side wall of the stirring cavity; the stirring cavity is internally provided with a stirring device; the partition plate is provided with a material falling hole; a discharging device isarranged at the bottom of the partition plate; and an opening device is arranged in the opening cavity. By adopting the air filter cotton preparation raw material mixing pretreatment process disclosed by the invention, rotating shafts are driven by gear transmission to rotate in different directions, so that a stirring rod is driven to perform staggered and reverse rotation; by arranging a vertical supporting rod outsides the stirring rod, a stirring range of the stirring rod in a vertical direction is expanded, and the stirring efficiency is improved; and a fibre agglomerate is opened by using burrs, driven by a reversely rotating rotary roller, on the surface of the rotary roller, and fibers attached to the surface of the rotary roller is scraped by a labyrinth plate, so that the situation that a subsequent fiber mass cannot be opened is avoided.

Description

technical field [0001] The invention relates to the technical field of filter cotton raw material pretreatment, in particular to a raw material mixing pretreatment process for air filter cotton preparation. Background technique [0002] As we all know, the air contains a lot of dust (such as dust, dust, smoke, mine dust, sand dust, powder, etc.) particles, because the weight of these dust particles is very light, so when the flowing air acts on these dust particles, the dust will The weight of the particles themselves is offset, so that these dusts are in a floating state. When people breathe, these dusts will be inhaled into the lungs, which is not conducive to human health. When working in places containing a lot of dust for a long time, it is necessary to wear a mask. Filter the inhaled air. To prepare the filter cotton, it is necessary to pour the fiber cotton with a good ratio into the mixer and stir, mix all kinds of raw materials evenly, and then use the licker-in ro...

AI Technical Summary

Problems solved by technology

[0003] The filter cotton raw materials have the following disadvantages in the process of stirring and opening: 1. When the mixer is stirring, the stirring rod can only rotate in the same direction, and the fiber cotton is lighter in weight and will rotate together with it, resulting in uneven mixing of the fiber cotton ; 2. When opening, the fiber clusters are easy to adhere to the surface of the licker-in roller device. When the thickness of the fiber clusters is thicker, the exposed length of the burrs of the licker-in roller device will decrease, causing the fiber clusters behind to open. Loose efficiency is low
