Description
Technical field
The present invention relates to silk cocoon throwing correlative technology field, a kind of infiltration of the secondary vacuum after thermophilic digestion is referred in particular to
Cocoons-boiling method.
Background technology
Cocoon cooking is the key operation together in Primary Processing, the quality of cocoon cooking quality except can directly influence reel silk from cocoons folding,
It is unwinding, moreover it is possible to the indices for influenceing deviation, cleaning, cleaning, raw silk cohesion etc. relevant with raw silk quality.
In fiber tow production field, the White Steam Filature Yarns quality of China is enjoyed a very good reputation always in the world, and total amount accounts for the world
First, cocoon cooking machine is retrofited upgrading also with continuing to develop for silk reeling equipment, is increased damp machine from initial daily output and is developed into vacuum and oozes
Saturating cocoon cooking machine, developing deeply to multifunctional adjustable cocoon cooking machine.These three types can mostly be divided into automatic cocoon feeding machine section, impregnation stage,
Cure bag, Tang Zhengduan, or increase steaming part for permeation.From structure composition, part and boiling (soup steaming) part are permeated all to divide
From state, need to manually pass and connect, there is the problems such as labor productivity is low, and energy resource consumption is high.
The content of the invention
The present invention is above-mentioned in order to overcome the shortcomings of to exist in the prior art, there is provided one kind improve silk reeling productivity and
The cocoons-boiling method of the infiltration of the secondary vacuum after thermophilic digestion of raw silk inherent quality.
To achieve these goals, the present invention uses following technical scheme：
A kind of cocoons-boiling method of the infiltration of the secondary vacuum after thermophilic digestion, specifically includes following steps：
(1) select silkworm：Dry silk cocoon is positioned under light, is selected silkworm by the way of manually selecting silkworm, removal light defective cocoon, Shuan Gong
Cocoon rotten cocoon with；
(2) first sub-percolation：The dry silk cocoon obtained in step (1) is put into infiltration bucket, vavuum pump is opened, made in infiltration bucket
After vacuum reaches 0.095-0.097MPa, infiltration water is added, water inlet is higher by silk cocoon；
(3) first draining：Open pipeline pump, by the silk cocoon after osmotic absorbent in addition to the water sucked in cocoon chamber, cocoon chamber
Outer infiltration water is discharged to low temperature with bucket；
(4) cocoon cooking：The steam pipe of infiltration bottom of the barrel is opened, the silk cocoon to being obtained in step (3) carries out thermophilic digestion；
(5) second permeation：Vavuum pump is opened, after the logical interior vacuum of infiltration is reached into 0.06-0.092MPa, infiltration is added
Water, make to obtain in step (4) the silk cocoon of part guttation absorbs water again under the conditions of thermophilic digestion, water inlet is higher by silk cocoon, its
The temperature of middle infiltration water is higher than the temperature of infiltration water in step (2)；
(6) secondary drainage：Pipeline pump is opened, the outer unnecessary infiltration water of the silk cocoon obtained in step (5) is entered into high temperature matches somebody with somebody
In bucket, 60% water is kept in infiltration bucket；
(7) spraying cooling：The spray header at the logical top of infiltration is opened, the silk cocoon to being obtained in step (6) is lowered the temperature；
(8) cocoon is gone out：Will be by the silk cocoon after step (7) treatment, loading is sent in cocoon bucket, filature workshop is transported to, as life
Product cocoon.
In cocoon cooking process, first negative-pressure penetration is basis before boiling, and thermophilic digestion is crucial with second permeation.Boiled routinely
In cocoon technique, this process is respectively adopted two kinds of different equipment to complete, and the second permeation of cage cocoon cooking machine long is in temperature difference bar
Completed under part, and integral intelligent cocoon cooking machine will complete the technological requirement of second permeation after boiling using an entire body, due to
Lack the condition of the temperature difference, it is impossible to meet the requirement of second permeation and cause more floating cocoon to produce, whether the completion of second permeation to be,
It is directly connected to silk reeling productivity and raw silk inherent quality.And the present invention is made using secondary vacuum pumping is carried out after thermophilic digestion
By the silk cocoon after thermophilic digestion under condition of negative pressure, second permeation is completed, more satisfactory cocoon cooking effect has been obtained, so that greatly
Improve silk reeling productivity and raw silk inherent quality greatly.Wherein：In step (5), vacuum must be controlled in 0.06-
Between 0.092MPa, when vacuum is less than 0.06MPa, floating cocoon is easily produced because vacuum is too low；Vacuum is higher than
During 0.092MPa, flat cocoon is easily produced because vacuum is too high.The temperature of infiltration water necessarily be greater than step (2) in step (5)
The temperature of middle infiltration water, it is therefore an objective to which internal layer is cooked degree in strengthening osmotic effect and improving silk cocoon.
Preferably, in step (1), described light is sunshine or light.
Preferably, in step (2), the temperature for permeating water is 30-35 DEG C, and water inlet is higher by silk cocoon 4-6cm, time of penetration
It is 3-4 minutes.So it is designed to ensure that silk cocoon can fully be permeated.
Preferably, in step (3), water discharge time is 1.5 minutes, described low temperature with being provided with temperature controller in bucket,
The temperature control of water will be permeated at 30-35 DEG C.So design cause low temperature with the infiltration water energy in bucket be enough recycled to
In step (2), water resource has been saved.
Preferably, in step (4), when thermophilic digestion is carried out, steam pressure is 0.1MPa, and boiling temperature is 65-
70 DEG C, digestion time is 4 minutes.So it is designed to so that the cocoon layer of silk cocoon is fully cooked.
Preferably, in step (4), by after thermophilic digestion, original infiltration water is told under high temperature action in cocoon chamber
Water rate control is 20%.By the strict control of guttation amount in cocoon chamber, can be only achieved cocoon layer and be cooked, permeate fully, improved with this
The reelability percentage of silk cocoon and the purpose of cleanliness factor.
Preferably, in step (5), the temperature for permeating water is 40-45 DEG C, and water inlet is higher by silk cocoon 4-6cm, time of penetration
It is 3-4 minutes.So it is designed to ensure that silk cocoon can be by secondary abundant infiltration.
Preferably, in step (6), water discharge time is 1 minute, described high temperature, will with temperature controller is provided with bucket
The temperature control of water is permeated at 40-45 DEG C.So design causes that low temperature is enough recycled to step with the infiltration water energy in bucket
Suddenly in (5), water resource has been saved.
Preferably, in step (7), at 40 DEG C, temperature fall time is 1 minute to silk cocoon temperature control.
The beneficial effects of the invention are as follows：Using secondary vacuum pumping is carried out after thermophilic digestion, make by the silkworm after thermophilic digestion
Cocoon completes second permeation under condition of negative pressure, has obtained more satisfactory cocoon cooking effect, so as to substantially increase filature production effect
Rate and raw silk inherent quality；Internal layer is cooked degree in enhancing osmotic effect and raising silk cocoon；Improve the reelability percentage of silk cocoon and clean
Cleanliness；Water resource is saved.
Brief description of the drawings
Fig. 1 is process chart of the invention.
