Multiple-roll dust filter

Abstract

The invention relates to an air filter, particularly relates to a filter for separating, collecting and removing fiber dust in a spinning workshop, and specially discloses a multiple-roll dust filter. The multiple-roll dust filter comprises a device shell, wherein one end of the shell is provided with an air-blower chamber, the other end of the shell is provided with a primary dust removing device, and the middle of the shell is provided with a secondary dust removing device; the secondary dust removing device comprises a roll type filtering drum, the center of the roll type filtering drum is provided with a rotating main shaft; the main shaft drives a plurality of dust suction pipes to rotate inside the filtering drum; the main shaft is a reciprocating screw with a thread at one end; a fixed shaft sleeve of the main shaft is provided with an oil storage device and the oil storage device is arrange on the upper part of the fixed shaft sleeve; the bottom of the oil storage device is provided with an oil dripping hole; and the fixed shaft sleeve is provided with a through hole at a part corresponding to the oil dripping hole, so that the fit clearance between the main shaft and the fixed shaft sleeve is communicated with the oil storage device. Lubricating oil is directly injected on the main shaft, thus the lubrication effect of the main shaft is good, the abrasion is reduced, the service life is prolonged, the using cost is saved and the multiple-roll dust filter has a positive effect for ensuring safety production.

Description

technical field [0001] The invention relates to an air filter, in particular to a filter for separating, collecting and removing fiber dust in a textile workshop, in particular to a multi-drum dust filter. Background technique [0002] At present, domestic textile enterprises mostly use centralized dust removal systems in textile workshops to meet the needs of production. Most of the existing air dust collectors are two-stage dust removal devices. The first stage separates larger dust particles, and the second stage filters fine dust. One of the multi-drum dust filters needs to use a suction pipe on the drum filter material to remove the fine dust of the filter material during the second stage of filtration. The suction pipe is driven by the reciprocating lead screw that rotates in the middle, so that the suction pipe forms a movement track that rotates around the axis and swings left and right along the axis. However, because the reciprocating lead screw here is in a high...

AI Technical Summary

Problems solved by technology

However, because the reciprocating screw here is in a high-concentration dust working environment, the screw is easy to wear and has a short service life.

And because the lead screw here is not a standard part, it is difficult to repair after damage, and the accessories are expensive, causing huge pressure and loss to the enterprise
