Description
Technical field
The present invention relates to a kind of fiber dewatering and vacuum drying methods, belong to fiber dehydration and drying technical field.
Background technology
Existing fiber drying method generally uses cross-flow drying, and dried medium is thermal current, and it is big that there are thermal losses, dry
The shortcomings that rate is low, fiber moisture uneven drying.Part uses far-infrared ray drying and dielectric drying, and it is big that there are power consumptions, dry
Disadvantage of high cost.
Invention content
The purpose of the present invention is to provide：Vacuum compartment (tank) is made for drying receptacle, with perforated trays or more with stainless steel
Hole case has for wet fiber material storage, is handling carrier with materials vehicle, is that heating is situated between with conduction oil using PTC element as heater
Matter, using heating agent working medium as heat-conduction medium, using vacuum heat-conduction chamber, vacuum heat conduction pipe as Thermal Conduction Equipment, with water ring vacuum pump negative pressure
Dehumidifier shows a kind of fiber dewatering and vacuum drying method of fiber moisture with moisture on-line detector automatically.It is low with temperature,
Fiber quality is improved, rate of drying is high, and dehydration is uniform, and drying cost is low, heats, vacuumizes the characteristics of dehydration is carried out at the same time.
The invention is characterized in that：Wet fiber material is packed into perforated trays or porous case, piles up on materials vehicle, is pushed into vacuum
In compartment (tank), ptc heater fast constant temperature heats conduction oil, and heating agent working medium incudes heat conduction oil temperature and generates heat of evaporation, and vacuum is led
Hot chamber, vacuum heat conduction pipe are to vacuum compartment (tank) interior isothermal radiation, water ring vacuum pump negative pressure dehumidifier, and wet fiber material physics depends on
Moisture escapes into gas phase, is evacuated compartment (tank) outside with air, moisture on-line detector shows fiber moisture automatically.
Specific implementation mode
Vacuum compartment (tank) is stainless steel structure sealing container, and peripheral wall forms vacuum heat-conduction chamber, and vacuum heat conduction pipe is vertically connected to
Lower wall on vacuum compartment (tank), vacuum compartment (tank) door are freely to open hermatic door；Perforated trays or porous case are stainless steel stretched punching
It is molded, overall dimensions equivalent materials chassis；Water ring vacuum pump is connected to through air flue with vacuum compartment (tank)；Moisture on-line detects
Instrument terminal, water ring vacuum pump, ptc heater power supply are drawn by console；PTC element symmetry is arranged above and below, both sides difference
Positive and negative electrode is bonded, insulation board is buckled in outside, is packed into heater case, is fixed in heat conduction fuel tank, is marked with and leads in heat conduction fuel tank
Deep fat, heat conduction fuel tank are fixed in longitudinal direction is multiple rows of in vaporization chamber, and heating agent working medium, vaporization chamber and vacuum heat-conduction are marked in vaporization chamber
Chamber, vacuum heat conduction pipe connection.Wet fiber material is packed into perforated trays or porous case, piles up on materials vehicle, push-in vacuum compartment
In (tank), vacuum compartment (tank) door is sealed；Heating power supply is opened, ptc heater fast constant temperature heats conduction oil, heating agent working medium sense
Heat conduction oil temperature is answered to generate heat of evaporation, heat of evaporation is with the speed of 80-120cm/S, through vacuum heat-conduction chamber, vacuum heat conduction pipe to vacuum
Compartment (tank) interior isothermal radiation, preheats 40min, and vacuum compartment (tank) interior temperature reaches 40-70 DEG C；Water-ring vacuum pumping source is opened, very
Negative pressure is presented in empty compartment (tank), gaseous pressure is low, and fibrous physics depend on moisture rapid evaporation and escape into gas phase, by water ring vacuum pump
It extracts vacuum compartment (tank) out outside, achievees the purpose that fiber dehydrates；Moisture on-line detector is shown by the mark of dry fiber automatically
Quasi- moisture.
Present example：Heating system, ptc heater rated voltage：220V, frequency：50HZ, it is warm in vacuum compartment (tank)
Degree：40-70℃；Vacuum dehumidifying system：Water ring vacuum pump rated voltage：380V, final vacuum：0.098Mpa, dehydration and drying
Period：30min, dry energy cost：0.01 yuan/Kg.
The present invention has temperature low, improves fiber quality, and rate of drying is high, and dehydration is uniform, and drying cost is low, and heating is taken out
The characteristics of vacuum dehydration is carried out at the same time.
The present invention is suitable for hair, fiber crops, silk, cotton, the dehydration and drying of chemical fiber and color and contaminates drying process, is cut suitable for wood
Piece, paper pulp fiber, timber, Chinese medicine, medicine materical crude slice are dry and flax soaks the dehydration and drying after macerating, and are also suitable cereal, paddy and cereal
The dehydration and drying of the drying of flowers and trees seed and veterinary antibiotics, food, tealeaves, fresh flower.
