Abstract

A frictionally-driven disc dust-filtering unit is a one level air return dust filtering device for the textile air-conditioning engineering, and is used for filtering the fiber dust in the air. The utility model is characterized in that the outer ring of a filter disc is regarded as a driven wheel and is directly driven by a friction roller. Thus the utility model has the advantages of compact structure, small ground occupation, low cost, short drive chains, few energy consumption and material saving.

Description

Frictionally-driven disc dust-filtering unit

Frictional drive disk dirt catcher is the one-level return air dust filtration equipment that the textile air-conditioner engineering is used, and is used for the fibroid dust of filtered air.

Past, one-level return air dust filtration equipment commonly used was a kind of fixed window, was covered with filter screen on window, and by the artificial fibroid dust of regularly removing on the filter screen, its filter efficiency is very low, and its labour health condition extreme difference is now superseded substantially.The disk return air dirt catcher that uses is a kind of filtration disk of slow rotation now, also is covered with filter screen on disk, and sweeper is housed, to replace artificial cleaning regularly.To filter disk and rotate a circle at a slow speed in order to obtain to make in tens of minutes, selected the complicated transmission device of being made up of motor, decelerator, eccentric wobble crank mechanism and ratchet mechanism etc. for use, its shortcoming is that mechanism is loaded down with trivial details, transmission chain length, energy dissipation are big etc.

The utility model is for overcoming a kind of new construction that above-mentioned shortcoming is developed.It is big to hundreds of centimetres to filter disk diameter by what, can directly serve as big driven pulley in the transmission system with it, with a diameter only several centimetres active friction roller be pressed on this big driven pulley and make friction rolling, just can obtain very big step-down ratio, thereby cancelled original eccentric wobble crank mechanism and ratchet mechanism, and huge frame, driving-chain so just shortened, energy dissipation is reduced greatly, and reduced floor space.

Filter the outer ring of disk and made by angle steel, have certain oscillating quantity owing to make mismachining tolerance on diametric(al), friction roller often is pressed on the outer ring of filtering disk in order to make initiatively, and its thrust is provided by the holddown spring that is installed on the swing base.When the swing of the filtration disk outer ring of friction, pre compressed magnitude when being installed by the what holddown spring is greater than the oscillating quantity of filtering the disk outer ring, therefore initiatively friction roller always has a kind of positive pressure filtering on the disk outer ring, and the frictional force that normal pressure produced thus can impel the filtration disk normally to rotate fully, and at its offside the balance friction roller is housed.Initiatively the outer rim of friction roller and balance friction roller is all selected the hard rubber manufacturing for use.

The utility model is compared with former disk dirt catcher, and its main feature has driving-chain short, and energy dissipation is few; Compact conformation, floor space is little; The material saving, equipment manufacturing cost is low etc.
