Description
Technical Field
The invention belongs to the technical field of papermaking, and particularly discloses a production system of natural-color bamboo pulp instant high-thickness paper.
Background
At present, the daily use paper in the market is mainly made of white toilet paper in the form of rolls and boxes. The household paper mainly pays attention to water absorption, comfort and instant solubility, most of the prior household paper products do not pay attention to the instant solubility, and the phenomenon that a sewer is blocked due to the household paper also happens occasionally. With the continuous improvement of the living standard of people, the demand for the use comfort of the household paper is increased, and in order to increase the use comfort of the household paper, the existing high-quality household paper has high thickness compared with common toilet paper, especially for toilet paper with high instant solubility, which leads to poorer instant solubility.
The bleached daily use paper contains fluorescent agent whitening agent, which can generate carcinogen and other harmful chemical substances, so that the daily use paper does not harm human body and environment, the daily use paper on the market tends to use natural color toilet paper, the raw material for manufacturing the daily use paper is changed from wood pulp into bamboo pulp, and the quick solubility of the toilet paper is poor due to the good tenacity of the fiber in the bamboo pulp paper.
At present, natural-color high-thickness household paper is prepared by adopting bamboo pulp, and the process usually comprises the steps of bamboo material crushing → bamboo material cooking → pulping → desanding → pulp mixing → papermaking. In the process of crushing the bamboo wood, the bamboo wood is usually cleaned and then cut into small sections by a cutting machine to realize crushing. However, a single bamboo fiber is slender, two ends of the bamboo fiber are sharp and in a spindle shape, the inner wall of the fiber is smooth, the cell wall is very thick, the cell cavity is small, and if the bamboo is cut and crushed by a cutting knife directly, the bamboo fiber on the cutting surface can be damaged. In addition, in order to increase the instant solubility of the natural color high-quality paper, a proper amount of reagents such as a softening agent, a stripping agent and the like are usually required to be added in the production process, the step is completed in the size mixing process, however, due to the high concentration of the bamboo pulp, the reagents such as the softening agent, the stripping agent and the like are not easy to be fully mixed with the bamboo pulp, and the instant solubility of the prepared natural color high-thickness household paper cannot be good.
Disclosure of Invention
The invention aims to provide a production system of natural-color bamboo pulp instant high-thickness paper, and aims to solve the problems that the existing natural-color high-thickness household paper is poor in bamboo material crushing effect and poor in size mixing effect in the production process.
In order to achieve the purpose, the basic scheme of the invention is as follows: a production system of natural-color bamboo pulp instant high-thickness paper comprises a pulping unit and a papermaking unit, wherein the pulping unit comprises a crusher, a cooking machine, a pulping machine and a desander, and the papermaking unit comprises a pulping machine and papermaking equipment; the crusher comprises a crushing box, a feeding hole and a discharging hole are formed in the crushing box, a beating and crushing unit for beating and crushing bamboo joints is arranged at the upper part in the crushing box, and a mashing unit for mashing the bamboo joints is arranged at the lower part of the beating and crushing unit in the crushing box; the size mixing machine includes the mixing box, be equipped with inlet pipe and discharging pipe in the mixing box, be equipped with a plurality of stirring rollers in the mixing box, the stirring roller is the multirow, two adjacent rows of stirring roller dislocation sets, and two adjacent stirring rollers carry out the roll-in formula stirring to thick liquids and mix.
The working principle of the basic scheme is as follows: when the system is adopted to produce the natural-color high-thickness paper, bamboo can be cleaned and cut into bamboo joints with certain length, and then the bamboo joints are sequentially treated by utilizing the crusher, the cooking machine, the pulping machine, the desander, the pulp mixer and the papermaking equipment of the system, so that the bamboo joints pass through the paper pulp unit and the papermaking unit to be made into the natural-color high-thickness paper.
When the breaker in this system carries out the breakage to the bamboo joint, pat the breakage to it earlier through clapping garrulous unit, this just need not to cut the bamboo joint once more, also can fully carry out breakage to the bamboo joint through patting the breakage, the integrality of the fibrous integrality of reservation bamboo joint that simultaneously can also be abundant. The bamboo joints which are broken by beating are smashed by the smashing unit, so that the bamboo joints can be broken to a proper degree, and the integrity of bamboo joint fibers is kept.
When the pulp mixer in the system is used for adjusting the bamboo pulp, reagents such as a softening agent, a stripping agent and the like can be added, so that the manufactured high-thickness paper has better instant property. In reagent accessible inlet pipes such as bamboo thick liquid and softener, stripping agent got into the mixing box, stirs through the stirring roller, through the stirring of multirow stirring roller to and the stirring of dislocation stirring roller, the bamboo thick liquid of high concentration was by extrusion formula intensive mixing, and then made reagent such as softener, stripping agent and bamboo thick liquid misce bene, thereby ensured the instant solubility of high thickness paper.
The beneficial effect of this basic scheme lies in:
1. this system can be directly carry out the breakage to the bamboo joint, need not to cut into the segment with the bamboo joint before the breakage, and the breakage adopts the mode of patting and pounding to pieces to go on, can enough fully break, also can keep bamboo fibre to keep intact after the breakage, and this high thickness paper of true qualities that has just guaranteed to produce can have higher quality.
2. In the process of mixing the bamboo pulp with the reagents such as the softening agent, the stripping agent and the like, the system adopts the pulp mixer to mix the bamboo pulp with the reagents, and adopts the roll-pressing type stirring, so that the reagents such as the softening agent, the stripping agent and the like are fully mixed into the high-concentration bamboo pulp, and the instant property of the natural-color high-thickness paper is further ensured.
Compared with the prior art, the system can fully crush bamboo joints without damaging bamboo fibers in the manufacturing process of the natural-color high-thickness household paper, so that the natural-color high-thickness paper can have higher quality; meanwhile, the bamboo pulp, the softening agent, the stripping agent and other reagents can be fully mixed in the pulp mixing process, and the instant property of the natural-color high-thickness paper is further ensured.
Further, the smashing unit comprises a driving mechanism, a bottom plate and a clapper, the feeding hole is aligned with the upper portion of the chassis, the driving mechanism drives the clapper to repeatedly clap towards the bottom plate, and a gap used for the smashed bamboo knots to leak is formed in the bottom plate.
