Description
Technical field
The present invention relates to a kind of tailings recovery and treatment method more particularly to a kind of paper-making pulping tailings fiber recovery methods.
Background technology
At present the country paper mill substantially use reclaimed waste paper as primary raw material progress pulping and paper-making, reclaimed waste paper due to
Its fibre length is shorter after recycled for multiple times, is lost in slurrying slurry by a large amount of staple fiber after pulping process,
Cause a large amount of fiber loss.And containing the impurity such as a large amount of plastics, iron wire, rubble in slurrying screenings simultaneously, processing is difficult, institute
Slurrying slurry can be filled with general paper mill.
With the enhancing of the public environmental consciousness of people, slurry landfill not only results in environmental issue, and leads to a large amount of fibres
The loss of dimension is unfavorable for causing the sustainable development of industry.
Invention content
The present invention overcomes the deficiencies in the prior art, provide a kind of paper-making pulping tailings fiber recovery method.
In order to achieve the above objectives, the technical solution adopted by the present invention is：A kind of paper-making pulping tailings fiber recovery method,
It is characterized in that, includes the following steps：
（1）After tailings is dried, dry tailings is crumpled using blender；
（2）Fiber dust earth mixtures is arrived into the tailings separation after rubbing by sieve；
（3）Blender rubbing fiber dust earth mixtures is reused, the isolated fiber of strainer is then passed through.
In a preferred embodiment of the present invention, step（2）After middle tailings isolates fiber dust earth mixtures, residue is modeling
Material, iron wire and rubble, isolate iron wire by magnet, go out plastics by FLOTATION SEPARATION.
In a preferred embodiment of the present invention, the sieve is bar shaped lattice structure, and the hole between adjacent cells is proper
Dust and fiber can be passed through well.
In a preferred embodiment of the present invention, step（3）In obtained fiber may further be gone by way of washing
Except remaining dust.
In a preferred embodiment of the present invention, step（1）In drying be to be dried by dry hot-air, or it is logical
Sun exposure is crossed to be dried.
In a preferred embodiment of the present invention, dry hot-air is constantly passed through during blender rubbing.
The invention solves the defect existing in the background technology, and the present invention has following advantageous effect：It, can be with by drying
Effectively by size in tailings at least more than the particulate matter of fiber an order of magnitude, block, tablet and bar decile
It separates out and, after dry, the various articles in tailings are not easy to be sticked together so that become using physics mode separation, screening
It may；Physically screening mode relative chemical method is used simultaneously, will not be improved and be generated pollutant, it is relatively friendly to environment.
It is synchronous also to collect out by Classification of materials such as iron, plastics in tailings by detaching the fiber process in tailings, point
It can also become available resource from original rubbish from materials such as the iron of concentration, plastics, turn waste into wealth.
Specific implementation mode
Presently in connection with embodiment, the present invention is described in further detail.
A kind of paper-making pulping tailings fiber recovery method, includes the following steps：
（1）After tailings is dried, dry tailings is crumpled using blender；
（2）Fiber dust earth mixtures is arrived into the tailings separation after rubbing by sieve；
（3）Blender rubbing fiber dust earth mixtures is reused, the isolated fiber of strainer is then passed through.
Step（2）After middle tailings isolates fiber dust earth mixtures, residue is plastics, iron wire and rubble, passes through magnetic
Iron isolates iron wire, goes out plastics by FLOTATION SEPARATION.
By drying, can effectively by size in tailings at least more than the particulate matter of fiber an order of magnitude, block,
Tablet and bar etc. are separated, and after dry, the various articles in tailings are not easy to be sticked together so that use object
Reason mode detaches, screens and is possibly realized；Physically screening mode relative chemical method is used simultaneously, will not be improved and be generated pollutant,
It is relatively friendly to environment.
It is synchronous also to collect out by Classification of materials such as iron, plastics in tailings by detaching the fiber process in tailings, point
It can also become available resource from original rubbish from materials such as the iron of concentration, plastics, turn waste into wealth.
Sieve is bar shaped lattice structure, the hole between adjacent cells just can by dust and fiber, bar shaped
Grid sieve can efficiently separate the dust sludge of fiber peacekeeping rubbing dusting.
Step（3）In obtained fiber remaining dust may further be removed by way of washing.
Step（1）In drying be to be dried by dry hot-air, or be dried by sun exposure.It utilizes
Sun exposure drying can be energy saving.
Blender rubbing during is constantly passed through dry hot-air, by the drying of hot-air, sludge be more prone to by
Dusting is crumpled, ensures that sludge will not adhesion fiber.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
