In the completely closed dust collecting chamber, most of dust can fall on the ground of the dust collecting chamber via the gravity function and a small amount of dust and airflow can be effectively separated via the cyclone. Therefore, the utility model attains the purpose of collecting dust, has the function of reducing noise and effectively reduces dust concentration. The utility model accords with national environment standards, assures workers' body health, recycles lots of useful fibers from exhausted waste gas and reduces resource waste.

Description

Cotton processing dedusting secondary returns the suede device

Technical field

The utility model relates to a dedusting secondary that grows cotton in processing and returns the suede device.

Background technology

In cotton processing, factory is for the ease of management, and makes in the dust laden air purification process collected dirt suede be convenient to cleaning to recycle, and generally adopting dry dust removal is primary dust removing, and the dedusting form has:

Gravity settling chamber: simple structure, resistance is less, and is durable in use; But need bigger construction area, the particularly fine dusts below 50 microns, indoor at gravitational settling because sinking speed is very little, general being difficult to purifies, and efficiency of dust collection is not ideal enough, and useful fiber is easy to clean and recovery not.

Cyclone dust collectors: simple in structure, easy to manufacture, limited as construction area, also can be installed in outdoorly, in the time of particularly in kindling material advances people's deduster, help preventing spreading of kindling material, safety effect is comparatively obvious; But resistance is big, power consumption is many, though efficiency of dust collection force of gravity expansion chamber height also is difficult to all purify to fibrous fine dusts.

Change net (dust cage) dirt catcher: simple in structure, it is big to handle air quantity, and resistance is little, small accommodation area; But because dust cage generally all adopts woven wire as filtering material, because of eyelet is bigger, staple fibre and fine dusts are more easily passed through, and not only lose fiber, and increase cleaning recovery burden, influence efficiency of dust collection.

Sack cleaner: the filter capacity to the fibroid fine dusts is better, and efficiency of dust collection is all higher than the deduster of above-mentioned several types; In a single day but it is all bigger with investment to handle the required construction area of same dust laden air amount, particularly has kindling material to advance in people's bag dust filter, very easily burning, even cause fire incident.The selection of filter pocket material directly influences the size of handling air quantity, just influence the size of dirt chamber area, the filter bag of same specification is as being twice than with bagging material processed air quantity with the polyamide fibre material, that is to say and handle same air quantity, dirt chamber area can reduce half.

Presort disembark (device): fine dusts and most air see through screen cloth and discharge, in coarse grained fibroid trifle in the world, be delayed at the inner surface of screen cloth, continue to be rotated down with the small part air, discharged by dirt suede impurity discharging port, useful fiber is convenient to cleaning and is reclaimed, and changes the dirt suede that filter screen order number can reclaim each link of cotton source mill effectively, and resistance is less, but efficiency of dust collection is low.

In order to reclaim useful fiber better, purify air, the cotton source mill that has is combined to form two-stage dust removal with above primary dust removing equipment, and the dustiness of discharged air is further reduced, as:

(1) cyclone dust collectors+gravity settling chamber;

(2) cyclone dust collectors+cyclone dust collectors;

(3) cyclone dust collectors+bag dust collector;

(4) change net deduster+gravity settling chamber;

(5) change net deduster+commentaries on classics net deduster;

(6) change net deduster+bag dust collector

(7) preseparator+gravity settling chamber;

(8) preseparator+commentaries on classics net deduster;

(9) preseparator+bag dust collector etc.

It is more that whirlwind dust excluder+bag dust collector two-stage dust removal is installed and used in cotton source mill the eighties, and dust removing effects is relatively good, because various reclaimers are equipped with better, the short flannel rate of recovery is also higher.Because of first order cyclone dust collectors, the fire dangerous situation is difficult for taking place.

At the beginning of the nineties, along with the popularization of new technology, preseparator+bag dust collector two-stage dust removal is installed and used more, superiority is more arranged, because all there is the secondary filter bag to filter, so dust removing effects is the same, and the one-level preseparator is littler than whirlwind dust remover resistance, and therefore, power consumption is little.On the other hand, preseparator has the cleaning effect that separates to dirt suede, and the dirt suede of recovery is cleared up well than the dirt suede that whirlwind deduster reclaims.Because the dirt suede that first order preseparator reclaims in time is transported to the cleaning equipment place and has gone, second level filter bag dedusting is again an air intake down, and the fire dangerous situation also is difficult for taking place.

No matter be primary dust removing or two-stage dust removal, in use also all have following problem:

The one, the inside and outside dust concentration of cotton job shop is too high, and serious environment pollution causes the worker to suffer from the respiratory illness, such as anthraco-silicosis etc., thereby grievous injury worker healthy.

The 2nd, contain a large amount of useful fibers in the waste gas of discharging, do not run off thereby do not add to reclaim, cause great waste, cause the reduction of economic benefit.

The 3rd, the quality of dedusting work has great influence to the safe handling of cotton processing equipment, and whether the safety in production that is directly connected to cotton processing enterprise can be carried out smoothly.The utility model through a large amount of tests, provides a kind of novel cotton processing dedusting secondary to return the suede device in order to overcome the problem in the existing dedusting, and this device can not only remove out dust effectively, and can also reclaim effective fiber automatically and reduce noise.

Summary of the invention

The utility model purpose is that the cotton processing dedusting secondary of design returns the suede device and is made up of blast pipe, dirt pocket, deduster, cyclone, time suede pipeline, baffle plate, steel bar, nylon wire and bucket; In process, the mixture of the ash that produces in the production process and suede is sent into intake stack by air blast to be entered in the deduster in the dirt pocket, under baffle effect above the deduster, form cyclonic air flow, when air-flow arrives the middle part of dirt pocket, because the control and the obstruct of nylon mesh number, effectively fiber falls in the bucket rotatably, be pressed into back the suede pipeline under self gas pressure in dirt pocket, effective fiber is recovered on the dust cage of job shop by returning the suede pipeline, thereby has reached the purpose that makes full use of effective fiber.In the dirt pocket of complete closed, most of dust is deposited on the ground of dirt pocket by the gravity effect, and a spot of dust effectively separates once more with air communication overwinding wind device, thereby reached the dedusting purpose, Feng Bi dirt pocket has played the effect that reduces noise simultaneously, effectively reduced the inside and outside dust concentration of cotton job shop, met the National Environmental standard, ensured that the worker's is healthy; From the waste gas of discharging, reclaim a large amount of useful fibers, reduced the waste of resource, increased economic efficiency, ensured safe smooth production.
