Description
Technical field
The application belongs to field of papermaking processes, specially a kind of cotton fiber processing unit (plant).
Background technique
The positive charge of cationic starch makes it in conjunction with negatively charged matrix, and can be by other negatively charged additives
It adsorbs and is maintained in matrix.Cotton fiber in process, when rubbing with metal part, often has negative electrical charge, to hydrophobicity
It is even more serious for synthetic fibers, if not only having good bonding force when with cationic starch starching with positive charge,
But also have the effect of eliminating electrostatic.
It is often used in cationic starch additive and electricity in paper industry, however existing addition manner is through entirely
Technical process, not only route is tediously long for existing paper technology, and needs using a large amount of cationic starch additive.
Summary of the invention
In order to solve the above-mentioned technical problem, this application provides a kind of cotton fiber processing unit (plant), the application is by following
What scheme was realized:
A kind of cotton fiber processing unit (plant), including by the sequentially connected mud pit of pipeline, destroies forebay, stuff box, fan pump,
Desander, deaerator, starching pump, pressurized screen, head box, wet end, press section, the first drying section, surface size press, second is dry
Portion, calendering device and crimping device, the head box is by pipeline and cationic starch case to being connected.
Preferably, the head box is connected by pipeline with auxiliary agent case.
Preferably, the pipeline of the head box and cationic starch case is equipped with flow control valve and flowmeter.
Preferably, the stuff box includes stuff box ontology, and two horizontal shafts are equipped in the stuff box ontology, the
One shaft is located at the top of the second shaft, is equipped with stirring blade in the first rotating shaft and the second shaft.
Preferably, the stirring blade is equipped with protrusion.
Preferably, the desander includes desander ontology, is successively arranged filtering from top to bottom in the desander ontology
Net, the first filter screen, the second filter screen and third filter screen.
Preferably, the surface of the third filter screen is curved surface.
Preferably, the bottom of the sand device ontology is connected with vacuum evacuation device.
Preferably, the third filter screen includes two parts, is followed successively by filter screen I and filter screen II from top to bottom, described
Filter screen I is cone, and the filter screen II is truncated cone-shaped, the bottom surface radius of the filter screen I and a bottom of filter screen II
The radius in face is identical, another bottom surface radius of the filter screen II is equal with the internal diameter of desander ontology.
The beneficial effect of the application is: the application is in the case where constant using cationic starch dosage, first-past retention
10% is improved, improves the reuse rate of cationic starch, ton paper reduces by 11.84 yuan of cost.
