Abstract
The invention relates to a drying method for raw silks in the technical field of silk production, in particular to a drying method for a re-reeled silk sheet. The invention aims at mainly solving the technical problems that in the prior art, because the silk sheet is dried by using steam generated by fire coal of a boiler in the re-reeled process, heat efficiency is lower, energy consumption is high, the temperature of a workshop is high, and the like. According to the drying method disclosed by the invention, an infrared heating tube with wavelength of 2-15 micrometers and power of 0.5-2kW is selected to dry the re-reeled silk sheet, wherein the distance between the infrared heating tube and the silk sheet is 5-30cm; and the humidity of a re-reeled carriage is controlled to be 42-50 percent and the temperature is controlled to be 32-36 DEG C. The infrared heating is free from a heat transfer medium and can be used for directly radiating and drying the silk sheet, so that compared with the conventional drying, energy consumption of silk sheet drying in the re-reeled work procedure is reduced over 25 percent, the temperature of the re-reeling workshop is also reduced by about 5 degrees and the work environment of workers for re-reeling in summer is greatly improved.
Description
Technical field
The present invention relates to the raw silk drying means in a kind of fiber tow production technical field, especially relate to a kind of drying means of re-reeled silk sheet.
Background technology
Rereeling is with little
The silk sheet returns into greatly
The production process of silk sheet or cone winded raw silk, the main purpose of skein finishing is that strand dress or cone winded raw silk are shaped well, hand touches soft, silk look and quality are unified, eliminate fault, prevent from cutting off, make strand dress or cone winded raw silk reach certain degree of drying and specification, so that storage, transportation and user use.What re-reeled silk sheet referred to is exactly large
The silk sheet.
At present, the heat drying of domestic reeling mill re-reeled silk sheet adopts traditional steam pipe heat form mostly.Its technological process is: steam (thermal source)---the dry re-reeled silk sheet of steam transmitting pipe, heating tube---vehicle cabin air---.This drying principles is mainly to rely on the heat of " conduction ", " convection current " to transmit form, with thermal energy transfer, gives the silk sheet, reaches drying purpose.Exist the thermal efficiency than low, the problems such as energy consumption large, workshop temperature height.
Summary of the invention
The present invention is to provide a kind of drying means of re-reeled silk sheet, and it is mainly to solve in the existing rereeling technique of prior art to rely on boiler fired coal and produce the dry silk of steam sheet, exist the thermal efficiency than low, energy consumption large, the high technical problem of workshop temperature.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
The described method of the drying means of a kind of re-reeled silk sheet of the present invention comprises:
A. silk sheet to be dried is wound on the large of rereeling machine interior
On, around the silk sheet infrared heating device being set, infrared heating device comprises infrared heating pipe and temperature, Humidity Detection control device, and the wavelength of infrared heating pipe is the 2-15 micron, and power is 0.5-2kW, to greatly
On a silk sheet carry out drying processing;
B. in the rereeling machine compartment, temperature maintains 32-36 ℃, and humidity maintains 42-50%;
C. with relative humidity in the rereeling machine compartment or temperature adjusting infrared heating device, when compartment relative humidity lower than setting value or temperature higher than when setting value, infrared heating device (infrared heating pipe and humiture detection control apparatus) stopped heating, when compartment relative humidity higher than setting value or temperature lower than when setting value, infrared heating device starts heating.
D. when large
On a silk sheet rereeling complete after (general a slice 20/22D raw silk is 180 grams, and the rereeling time is about 6 hours),, with silk sheet taking-up rereeling machine compartment, complete the drying work of a sheet.
, than the low 5-10 degree of the compartment temperature of conventional drying, therefore, make the environment temperature decline 5 degree left and right in summer, rereeling workshop due to temperature in the rereeling compartment that uses, greatly improved rereeling in summer workman's working environment.
The present invention can adopt on existing rereeling machine basis, closes original steam pipe, and the method for installation infrared heating tube and controller has a repacking convenient, and cost is low, the characteristics such as is easy to apply.
Save the complex device such as the required coal-burning boiler of traditional steam drying, jet chimney, saved factory
Space, make maintenance simpler.
As preferably, described infrared heating device is 5-30cm from the distance of silk sheet.
As preferably, described when rereeling machine compartment relative humidity during lower than 42-45%, the infrared heating device stopped heating; During higher than 48-50%, infrared heating device starts heating when rereeling machine compartment relative humidity.
As preferably, described when rereeling machine compartment relative temperature during higher than 36 ℃, the infrared heating device stopped heating; During lower than 32 ℃, infrared heating device starts heating when rereeling machine compartment relative humidity.
As preferably, described in rereeling machine compartment relative humidity lower than 42-45%, under the extreme conditions of simultaneous temperature lower than 32 degree, adopt temperature adjusting method; , higher than 48-50%, under the extreme condition of simultaneous temperature higher than 36 degree, adopt the humidity regulation method when rereeling machine compartment relative humidity.
Therefore, the present invention utilizes medium wave or the heating of far infrared fluorescent tube, directly the silk sheet is carried out drying when rereeling, MID INFRARED has very strong penetration capacity, does not need heat transfer medium during heating, therefore saved in existing re-reeled silk sheet dry run, boiler fired coal produces steam, vapor transmission,, the loaded down with trivial details operations such as steam pipe vehicle cabin air, have that the thermal efficiency is high, hygienic environment-protecting, descend 20% characteristics of energy consumption.
