Abstract
The present invention relates to a kind of method for cleaning felt gluing thing, the cleaning method after thing serious pollution is glued for woollen blanket, using gasoline or kerosene as the solvent borne mode of washing of cleaning agent, is thoroughly cleaned comprehensively in combination with physics washing system with reaching.Compared with prior art, the present invention can carry out the pollutant of carpeted surface comprehensive covering cleaning, and cleaning process persistently carries out, and it is high, small to systematic influence of manufacturing paper with pulp to damage relatively low and cleaning efficiency to woollen blanket.
Description
Technical field
The present invention relates to field of papermaking processes, more particularly, to a kind of method for cleaning felt gluing thing.
Background technology
Felt is one of most important building block of modern paper machine, is mainly used for the shaping and conveying of page.
Woollen blanket can be subject to different degrees of pollution during production and application, and necessary rational cleaning and maintenance just seem
It is particularly significant.Woollen blanket pollutant mainly includes two types:1st, gluing thing pollutes, resin, organic synthesis mainly in slurry
Various auxiliary agents be attached on fibrous raw material, filler surface or free cause to deposit and stick in the slurry;2nd, fiber fines, fill out
Material etc. blocks woollen blanket.
Felt washing mode is divided into two kinds:Physics washs and chemical washing, and physics washing is mainly inhaled with shower water and vacuum
Based on water tank is used cooperatively;Chemical washing then includes alkaline washing, acidic cleaning, solvent borne washing.
Acidic cleaning is mainly cleaned using 3% hydrochloric acid, sulfuric acid, the dilution of phosphoric acid, it is desirable to pH>1.8, temperature control
System is preferable to gluing physical property pollutant washing effect at 40-50 DEG C, wash time 20min, may reduce system pH.
Alkaline washing is mainly cleaned with the sodium hydroxide of 10-15%, potassium hydroxide dilution, it is desirable to pH>14, temperature
Control is at 50-60 DEG C, wash time 20min, to woollen blanket pollution cleaning caused by uncured resin or other alkali-soluble substances
Positive effect, but a large amount of foams influence white-water systems can be produced.
Solvent borne washing mainly carries out single-point cleaning using organic solvents such as gasoline, kerosene as cleaning agent, with old woollen blanket
Points of contamination is washed by rubbing with the hands after (or hairbrush) immersion solvent, cleaning performance is obvious under normal circumstances, but the process washed by rubbing with the hands to woollen blanket
In be likely to result in woollen blanket fluffing, and when woollen blanket is really heavily contaminated, be not suitable for using this method.
It is all less desirable that three of the above mode of washing is glued the cleaning performance after thing serious pollution for woollen blanket, even if
Expected cleaning performance cannot still be reached by increasing cleaning agent dosage or extending scavenging period.Also wool fibre can all be made at the same time
Into damage, woollen blanket service life is influenced, new woollen blanket may be replaced when serious, causes the increase of production cost.So exploitation one
Cleaning method of the kind when woollen blanket is glued thing serious pollution needs very urgent for production.
Chinese patent CN101768889A discloses a kind of felt cleaning device for paper machine, and felt cleaning device is
Steam-type felt cleaning device, it is located at the rack of paper machine felt leading roll, and wherein steam-type felt cleaning device includes:With hair
The vertical main steam range of cloth traffic direction;The steam branch pipe in the same direction in main steam range and with felt traffic direction is arranged on, it is described
Steam branch pipe is equipped with the nozzle between felt distance 6-8cm, also provides paper machine and felt containing felt cleaning device
Cleaning method, but this method still can not effectively remove the gluing thing on woollen blanket.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of cleaning efficiency is high, keeps away
Exempt from repeated washing, there is the method for cleaning felt gluing thing of apparent cleaning performance.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of method for cleaning felt gluing thing, using following steps:
(1) paper machine is shut down, and closes wet end shower water, and the moisture in woollen blanket is aspirated by vacuum system;
(2) machine water pond blowdown valve is opened;
(3) one layer of old woollen blanket is covered on woollen blanket to be cleaned;
(4) operating rate for controlling wet end of machine is 10-20m/min;
(5) gasoline or kerosene are poured on old woollen blanket and woollen blanket contact surface to be cleaned;
(6) stop after pouring oil, control the operating rate of wet end of machine to continue wet end for 10-20m/min and creep 20-30min,
The old woollen blanket operation of woollen blanket traction to be cleaned, ensures gasoline or kerosene can comprehensively soak gluing thing on woollen blanket to be cleaned and progressively
Dissolving;
(7) wait the wet end that stops after soaking, remove old woollen blanket;
(8) wet end operating speed is controlled first to open vacuum system, be then turned on woollen blanket high pressure water and spray in 200-400m/min
Water drenching, high-pressure water pressure are controlled in 4-6bar, run 10-15min, are broken up dissolved gluing thing using high pressure water, are led to
Cross vacuum suction case and detach carpeted surface, that is, complete the cleaning to woollen blanket.
The width of old woollen blanket is not less than woollen blanket to be cleaned, length for woollen blanket to be cleaned carpet surface to methods, rack on paper machine both sides
1.2-2 times of vertical range.
By old woollen blanket tie up paper machine laterally walk on stage lower section rack on and naturally droop it, front face woollen blanket to be cleaned
And old woollen blanket is spread out along woollen blanket traffic direction.
Gasoline or kerosene are poured into a mould within the 1-3 cycle of wet end of machine operation.
Compared with prior art, the present invention has the following advantages:
(1) this cleaning way has obvious cleaning performance after woollen blanket is really heavily contaminated, and passes through step (5) so that woollen blanket
The pollutant on surface can be dissolved in gasoline, then by step (6), woollen blanket is soaked in gasoline for a long time so that woollen blanket
Pollutant in gap can fully dissolve, and be allowed to depart from woollen blanket and play clean effect;
(2) it is applied widely;
(3) this cleaning way is mainly by the use of gasoline or kerosene as cleaning agent, using it to the effective of gluing thing or resin
Dissolving has reached cleaning purpose, to wool fibre without directly affecting.
(4) cleaning efficiency is high, avoids repeated washing;
(5) it is small to paper machine Influence of production, improve paper machine operation efficiency;
(6) it is small on the influence of system plain boiled water, a large amount of foams will not be produced.
