As further improvement of these options, described dewatering plate is provided with two groups, first be mounted on table roll after, second be mounted on wet vacuum tank after, wherein second group of dewatering plate number is the twice of first group of dewatering plate number.
As further improvement of these options, the material of described wet vacuum tank is zirconia ceramics.
As further improvement of these options, the vacuum ranges of described wet vacuum tank is: 80-120 millimetres of mercury, and the vacuum ranges of dry vacuum case is: 120-200 millimetres of mercury, is progressively increased respectively by left-to-right vacuum.
As further improvement of these options, described ornamenting roller is located between two groups of dry vacuum casees, and rotating speed is set to 150-200r/min.
As further improvement of these options, described idler roller is supporting is provided with stretcher and tension controller, and operationally, the tension force according to forming net regulates, and makes it remain enough tension force.
The utility model has the following advantages compared to existing technology:
(1) zirconia ceramics has the advantages such as hardness is high, ABRASION RESISTANCE good, toughness is high, coefficient of friction is low, good corrosion resistance, its coefficient of friction is very low, wet vacuum tank and dry vacuum case of wet end uses zirconia ceramics to overcome pottery fragility inherently, ABRASION RESISTANCE is higher, and its service life is greatly extended;
(2) the different dewatering plate of number is set respectively before wet vacuum tank with dry vacuum case, ensures dehydrating amount, the disturbance performance to slurry can be improved simultaneously, reduce power consumption;
(3) vacuum of described wet vacuum tank and dry vacuum case is set to and progressively increases, and contributes to l Water Paper page and evenly dewaters in advance process, reduces energy consumption;
(4) ornamenting roller is by the coated stainless (steel) wire of hollow roller drum, can reduce equipment cost, arranges corresponding rotating speed, can improve the evenness of l Water Paper page frame table bond strength and paper, and the two sides being lowered into paper is poor.
