Abstract

The invention relates to a method for filtering eiderdown threads, in particular to a method for filtering the eiderdown threads based on static by using the static to control the form and the moving direction of the eiderdown threads in an electric field so as to achieve eiderdown thread removal, and belongs to the technical field of eiderdown thread processing. The method uses wind power to fully disperse eiderdown flowers and the eiderdown threads, and utilizes the static to control the form and the moving direction of the eiderdown threads in the electric field so as to accurately separate the eiderdown threads from the eiderdown flowers, achieve filtration of the eiderdown threads through a filter screen, and effectively improve the quality of the eiderdown by using the technique.

Description

Down fiber filter method based on static

Technical field

The present invention relates to a kind of down fiber filter method, control the form of staple in electric field and the down fiber filter method based on static of direction of motion realization removal staple, belong to the eider down processing technique field thereby relate in particular to a kind of static that utilizes.

Background technology

The composition of eider down is mainly suede piece, staple and other impurity, and the content of its medium staple piece is the highest, and according to different finished product eider downs, content from 60% to 90% does not wait; Staple takes second place, content from 9% to 39%; Impurity content is generally about 1%.Staple all not as suede piece, is exactly to reduce staple content so improve crucial in the eider down quality one on loft, warmth retention property.At present both at home and abroad how eider down manufacturing enterprise reduces the problem that generally faces on the staple content and is: in actual production at present, generally only be to use wind-force to come suede piece and non-suede class impurity in the separate raw materials.And the density of staple and suede piece is close, so wind-force can only dispel them, and can't staple be filtered out.To the equipment that staple filters thereby report is not arranged as yet for utilizing static to control the form and the direction of motion reality of staple in electric field both at home and abroad at present.

Summary of the invention

The objective of the invention is for overcoming the weak point of above-mentioned prior art; A kind of down fiber filter method based on static is provided; This method uses wind-force fully to disperse suede piece and staple; Utilize static to control form and the direction of motion of staple in electric field, realized filtration to staple through screen pack.

The present invention realizes with following technical scheme: a kind of down fiber filter method based on static, and this method comprises: the wind-force eider down separates, the steam spraying, filter based on the staple morphology Control and the staple of static;

(1) the wind-force eider down separates: utilize wind-force that eider down is fully disperseed in a container, realize fully separating of suede piece and staple;

(2) steam spraying: at suede piece and staple after separating, spray into steam, make suede piece fully absorb moisture, become conducting medium by insulator with staple;

(3) based on the staple morphology Control of static: suede piece touches negative electrical charge on the netted negative pressure strip with staple after absorbing moisture; Get into after the electric field; Because polarization, staple head and the tail stressed grade the in two ends and stretching and suede piece moves to the positive plate direction together by electrostatic force;

(4) staple filters: before positive plate, establish screen cloth one, sectional area is less after being straightened can pass for staple, and suede piece can't pass because sectional area is big.

Described screen cloth is the net by motor-operated continuous rolling.

Advantage of the present invention is: this method uses wind-force fully to disperse suede piece and staple, utilizes static to control form and the direction of motion of staple in electric field, accurately staple and suede piece is separated, and has realized being directed against the filtration of staple through screen pack.Use the quality that this technology effectively raises eider down.

The specific embodiment

A kind of down fiber filter method based on static, this method comprises: the wind-force eider down separates, the steam spraying, filter based on the staple morphology Control and the staple of static;

The wind-force eider down separates:

In one container, drop into a certain amount of eider down, the air-flow that is blown into through blower fan then is well dispersed in eider down in this vessel space, makes each suede piece all fully contact with air with staple.

The steam spraying:

Under eider down maintains suede piece and state that staple separates, import the steam spraying, piece fully contact with steam owing to suede like this with staple.Like this by two benefits: the first, suede piece increases with staple weight, helps to reduce air-flow for removing the staple influence.The second, let suede piece and staple become conducting medium, strengthen the polarization effect in electric field, staple and suede piece become weight after moisture absorption, and air-flow can't support and begin to the whereabouts.

Staple morphology Control based on static:

When suede piece falls with staple, can run into netted negative pole metallic plate and be with negative electrical charge; Polarize after getting into electric field; Owing to itself just have negative electrical charge; So bigger than the pulling force of negative plate from the pulling force of positive plate, this is two by two benefits: suede piece all can be in a stretching state with staple.But difference is that staple is a vertical bar shaped, so sectional area is less, and suede piece is owing to self be actiniform, so sectional area is bigger.Be convenient to filter staple like this, stay suede piece.Suede piece all can move to the positive plate direction with staple, and direction of motion rule is convenient to filter.

The staple screen pack:

Before positive plate, place a screen pack, because staple is a vertical bar shaped, so sectional area is less; And suede piece is owing to self be emission shape umbrella-shaped structure, so sectional area is bigger, its diameter is about more than 3 times of staple maximum gauge; The screen pack mesh diameter is the 0.8-1 millimeter; So when the screen pack, staple can pass, suede piece then can be filtered net and block.So just can filter out staple effectively and stay suede piece.Piece block simultaneously the staple of back for fear of suede; Make the staple of back to influence filter effect through screen pack; Screen pack is the net by motor-operated continuous rolling; The motor drives screen pack moves to outside the electric field, cleans after through collecting device suede piece being taken off, clean accomplish after again circulation get into electric field inside and filter.

Claims

1. down fiber filter method based on static, it is characterized in that: this method comprises: the wind-force eider down separates, the steam spraying, filter based on the staple morphology Control and the staple of static;

2. a kind of down fiber filter method based on static according to claim 1 is characterized in that: described screen cloth is the net by motor-operated continuous rolling.
