Description
Technical field
The present invention relates to drying technology field, more particularly to a kind of copper-plated steel wire drying system.
Background technology
Current steel wire continuous copper electroplating Final finishing needs Seal treatment, washing, drying process;The production of steel wire manufacturing enterprise
Steel wire pickling line, galvanized wire and enamel-covered wire, color-coating line are typically also required to be dried with air flow dryer, and other furnace drying methods are used
Dry and come with some shortcomings again in metal wire rod.General drying extracts 20 or so DEG C of air air inlet heaters of room temperature with blower fan
150~180 DEG C are inside heated to, the air of heating transfers heat to metal wire rod while wet metal line surface is sprayed to, simultaneously
The wet vapor of metal wire material surface is taken away, so that wet metal wire rod is dried.Hot-air is after drying metal wire material surface, entirely
Portion or small part discharge are supplemented by air at room temperature, cause great energy waste, heat utilization ratio is not high.Due to high humidity environment
Deng factors reason, dry not thorough copper-plated steel wire surface and washmarking occur or change colour quickly, make properties of product and appearance
Reduction.Metal wire rod drying majority is to dehydrate, also have de- organic solvent to dry.The purpose of copper-plated steel wire drying is exactly to incite somebody to action
The moisture film of line adsorption is removed after copper-plated steel wire washing, and the drying course of prior art is usually that metal wire rod is placed in into drying
In case and continue through, metal wire rod is heated by the overfire air for entering drying baker in drying baker, makes cleaning remained on surface
Organic solvent volatilization in moisture or paint vehicle in moisture, paint vehicle, completes to dry with the gas drying metal wire rod of heating to the greatest extent
Process.The drying metal wire rod Track character of prior art is that only small part hot-air is contacted with metal wire material surface, big portion
Hot-air inefficient cycle is divided to pass through;And vapor or organic solvent, when reaching certain humidity, will also be discharged in hot-air
Part hot-air is supplemented moisture or solvent saturation degree in low temperature dry air, reduction recirculated hot air, completes wire rod to environment
Drying course;Also have in hot gas cycle pipe-line system plus condensing unit, moisture or solvent saturation degree are complete in reduction recirculated hot air
Into metal wire rod drying course.Condensing unit is set up in hot air circulating system, although water smoke is condensed into aqueous water discharge, but
The also cooled cooling simultaneously of circulation air composition, increases energy consumption;Discharge unit high humility high temperature hot gas body supplements part low humidity
Cold air, while also having supplement part low humidity cold air, and other harmful substances are incorporated into heat dust in air etc.
In wind circulation drying system;In damp atmosphere environment, dry mass can not ensure.Optimal scheme is hot air circulation drying
Vent water vapor, while high-quality, high speed, high reliability dry metal wire rod.
The content of the invention
, can be to plating the present invention solves the technical problem of a kind of hot air circulation drying system of copper-plated steel wire is provided
Copper steel line and various metal wire material surface coatings or the water or solvent of cleaning there is provided the drying dry gas of continuous-stable, from
Separation, conveying vapor or gaseous solvent in Drying, and discharged from hot-air circulation line, improve metal wire rod table to the greatest extent
Face high speed, high-quality drying.
