Description
Technical field
The present invention relates to be applied to the continuous mill beating equipment of pulp and paper industry, be specifically related to the refining equipment of hydraulic regulation specific beating pressure, promptly middle dope is pressed double disc refiner.
Background technology
In papermaking process, making beating is a crucial link, have the title of " making beating in seven fens, three minutes copy paper ".The making beating mode is divided into basic, normal, high dense three kinds of forms by beating consistency, and low consistency pulping mainly relies on cut-out and the friction making beating of abrasive disc to fiber, is main with cut staple, and wire-dividing broom purification is auxilliary, is suitable for the making beating of the former wood pulp of long fiber; Middle and high consistency pulping mainly relies on fiber and fiber internal friction to make the fiber wire-dividing broom purification, cuts off and lacks, and is suitable for the making beating of staple fibre grass plasmoid, secondary stock secondary stock.The making beating of quovis modo, final purpose are in order to obtain good fibre morphology, and the stream of the back paper pulp that is beneficial to pull an oar send the formation with page.Therefore, selecting efficient, energy-conservation stable beating equipment and making beating mode is the key that obtains good fibre morphology.Existing beating equipment mainly contain worm and gear regulate the double plate mill of advance and retreat cutter, cone mill and in dense mill.The double plate that worm and gear is regulated the advance and retreat cutter grinds the low consistency pulping that only is suitable for 3 ~ 6% concentration, stifled slurry phenomenon when concentration is higher than 6%, can occur; It is lower that cone mill is suitable for concentration.
The making beating that worm screw is regulated the forward and back cutter is a kind of rigidity making beating of the gap of pulling an oar surely; With cut staple is main, although and middle and high dense mill is suitable for the middle and high consistency pulping of concentration 6% ~ 30%, the fiber wire-dividing broom purification is main; Cut off few; Dense mill can be decided the specific pressure making beating in the hydraulic regulation, has only a mill chamber, is made up of a Moving plate and a price fixing.During same disk diameter, its defibrination area has only the half the of double plate mill, even defibrination speed improves, comprehensive defibrination efficient is also lower.In order to obtain good fibre morphology, therefore, invent a kind of efficiently, energy-conservation, it is significant to take into account the pull an oar beating equipment of advantage of low dense double plate mill and middle and high dense mill.
Summary of the invention
In order to overcome existing defective and the inefficient shortcoming of the comprehensive defibrination of middle and high dense mill that double plate grinds, cone mill only is suitable for the low consistency pulping of 3 ~ 6% concentration of regulating the advance and retreat cutter by worm and gear; The present invention provides a kind of continuous defibrination or beating equipment that is applied to pulp and paper industry; Dope is pressed double disc refiner promptly; Suitable beating consistency is 6 ~ 12%, regulates specific beating pressure through hydraulic pressure.
