Stripping-sticking aid mixed jet device for paper production

Abstract

The invention relates to a stripping-sticking aid mixed jet device for paper production. Stripping-sticking aids include a cylinder sticking agent, a stripping agent and an improver. The cylinder sticking agent, the stripping agent and the improver the cylinder sticking agent are mixed quantitatively and evenly by the mixed jet device, and then added to the cylinder surface of a drying cylinder evenly. The mixed jet device includes a main pipeline, wherein a jet system used for jetting the mixed stripping-sticking aids on the cylinder surface of the drying cylinder is arranged at the tail endof the main pipeline; and the mixed jet device further includes a first supplying system for supplying warm water to the main pipeline, a second supplying system for supplying stripping-sticking aidsto the main pipeline, and a pumping system arranged on the main pipeline. The stripping-sticking aid mixed jet device for paper production adopts automatic process control, manual operation is avoided, the adding quantity of the stripping-sticking aids is more accurate, and mixing is more uniform. The expected effect can be achieved with the addition of the stripping-sticking aids, the product quality is improved, and the whole process is fast, and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a stripping auxiliary agent mixing and spraying device for paper production. Background technique [0002] At present, when producing crepe paper, the paper is dried by a dryer, and then wrinkled after a strong impact with a scraper, so as to improve the softness, water absorption, bulk and other properties of the paper, and at the same time obtain a good feel. This requires proper adhesion between the paper and the drying cylinder, especially in the production process of medium and high-speed paper machines. Paper sticking occurs, in order to reduce and eliminate these phenomena, it is necessary to rely on the use of peeling aids (including sticking agents, stripping agents and improvers) to adjust, so as to control the thickness of the lines, the depth of wrinkles and the smoothness of the paper surface degree etc. If the peeling aid is used improperly or has poor performance, it will not only have a great impact on the qua...

Problems solved by technology

If the peeling aid is used improperly or with poor performance, it will not only have a great impact on the quality of the paper, but also cause problems such as pinholes, dead lines and holes, and even cause jumping of the knife, resulting in damage to the dryer

Before the peeling aid is added to the pulp, the components of the sticking agent, the stripping agent and the modifier need to be mixed. In the prior art, the ingredients are mixed and added to the pulp by manual weighing. This method The method of manual weighing and mixing will inevitably lead to the problem of weight accuracy and impurity cannot be removed (the sticky impurities, residues, etc. have strong adhesion with the surface of the dryer, which will cause the paper to come out at the bonding point when it is taken out of the cylinder. tearing), and the mixing effect of each agent component cannot be effectively guaranteed, resulting in the failure to form the expected addition effect, and this manual method not only increases the labor intensity of the operator, but also the laborious and slow mixing speed, the operation The efficiency is also very low; in addition, in the prior art, most of the peeling aids are added to the pulp in the pulp supply tank and mixed with the pulp, which causes the problem of production continuity, and cannot effectively guarantee the efficient, continuous, and continuous production of the crepe paper production system. Uninterrupted operation, and the chemical composition of the various agents added to the pulp poses a serious test to the safety of the subsequent produced paper
