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 with reaching in combination with physics washing system.Compared with prior art, the present invention can carry out comprehensively covering cleaning to the pollutant of carpeted surface, and cleaning process is persistently carried 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 in the shaping and conveying of page.
Woollen blanket can be polluted during production and application by different degrees of, and necessary rational cleaning and maintenance are with regard to aobvious
Obtain particularly significant.Woollen blanket pollutant mainly includes two types：1st, the pollution of gluing thing, the mainly tree in slurry
Fat, the various auxiliary agents of organic synthesis be attached on fibrous raw material, filler surface or it is free cause in the slurry deposition and
Stick；2nd, fiber fines, filler etc. block woollen blanket.
Felt washing mode is divided into two kinds：Physics is washed and chemical washing, and physics washing is main with shower water and vacuum
Based on suction box is used cooperatively；Chemical washing then includes alkaline washing, acidic cleaning, solvent borne washing.
Acidic cleaning is mainly cleaned using the dilution of 3% hydrochloric acid, sulfuric acid, phosphoric acid, it is desirable to pH>1.8,
, at 40-50 DEG C, wash time 20min is preferable to gluing physical property pollutant clean result, may for temperature control
Reduction system pH.
Alkaline washing is mainly cleaned with the NaOH of 10-15%, potassium hydroxide dilution, it is desirable to pH>14,
At 50-60 DEG C, wash time 20min causes temperature control to uncured resin or other alkali-soluble substances
Woollen blanket pollution cleaning performance substantially, but can produce a large amount of foam influence white-water systems.
Solvent borne washing mainly carries out single-point cleaning using organic solvents such as gasoline, kerosene as cleaning agent, uses old hair
Points of contamination is washed by rubbing with the hands after blanket (or hairbrush) immersion solvent, generally cleaning performance is obvious, but to woollen blanket
Woollen blanket fluffing is likely to result in during washing by rubbing with the hands, and when woollen blanket is really heavily contaminated, is not suitable for using the 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, i.e.,
Increasing cleaning agent consumption or extension scavenging period is set still to reach expected cleaning performance.Simultaneously also all can be right
Wool fibre is caused to damage, and influences woollen blanket usage cycles, and new woollen blanket may be changed when serious, causes production cost
Increase.So develop a kind of cleaning method when woollen blanket is glued thing serious pollution for production need it is very urgent
Cut.
Chinese patent CN101768889A discloses a kind of felt cleaning device for paper machine, felt cleaning dress
Steam-type felt cleaning device is set to, it is located at the frame of paper machine felt leading roll, wherein steam-type felt cleaning device
Including:The main steam range vertical with felt traffic direction；It is arranged in main steam range and in the same direction with felt traffic direction
Steam branch pipe, the steam branch pipe is provided with the nozzle between 6-8cm with felt, also provides clear containing felt
The paper machine and felt cleaning method of cleaning device, but the method still cannot effectively remove the gluing on woollen blanket
Thing.
The content of the invention
The purpose of the present invention is exactly to provide a kind of cleaning efficiency for the defect for overcoming above-mentioned prior art to exist
It is high, avoid repeated washing, the method for the cleaning felt gluing thing with 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 blowoff 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) after stopping pouring oil, the operating rate of wet end of machine is controlled to be creeped for 10-20m/min continues wet end
20-30min, the old woollen blanket operation of woollen blanket traction to be cleaned, it is ensured that gasoline or kerosene can comprehensively soak woollen blanket to be cleaned
On gluing thing and progressively dissolve；
(7) stop wet end after immersion terminates, and removes old woollen blanket；
(8) control wet end operating speed first opens vacuum system in 200-400m/min, is then turned on woollen blanket high pressure
Water and shower water, high-pressure water pressure control runs 10-15min in 4-6bar, will be dissolved using water under high pressure
Gluing thing is broken up, and carpeted surface is detached by being sucked by vacuum case, that is, complete the cleaning to woollen blanket.
The width of old woollen blanket is not less than woollen blanket to be cleaned, and length is the carpet surface of woollen blanket to be cleaned to machine above paper machine both sides
1.2-2 times of frame vertical range.
By old woollen blanket tie up paper machine laterally walk on stage lower section frame on and naturally droop it, front face hair to be cleaned
Blanket simultaneously spreads out old woollen blanket 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 advantages below：
(1) this cleaning way has obvious cleaning performance after woollen blanket is really heavily contaminated, and by step (5), makes
The pollutant for obtaining carpeted surface can be dissolved in gasoline, then by step (6), woollen blanket is soaked in vapour for a long time
In oil so that the pollutant in woollen blanket gap can fully dissolve, the effect for departing from woollen blanket and playing cleaning is allowed to；
(2) it is applied widely；
(3) this cleaning way is mainly by the use of gasoline or kerosene as cleaning agent, using it to gluing thing or resin
Effectively dissolving has reached cleaning purpose, to wool fibre without directly affecting.
(4) cleaning efficiency is high, it is to avoid repeated washing；
(5) it is small to paper machine Influence of production, improve paper machine operation efficiency；
(6) small is influenceed on system plain boiled water, a large amount of foams will not be produced.
