Detailed Product Description: | Products chopping board and a vacuum zone is relatively long pulse of relatively low degree of vacuum effect, and adjacent to the pulse chopping board can be connected together more closely performance parameter front plane and the leading edge angle: front plane length is generally 10 ~ 15 mm, the leading edge angle β is generally 40 ~ 60 °, the size of the leading edge angle β, can affect the chopping edge scraping white water attached network efficiency below the leading edge of the card and preventing the problem of pulp, and thus to determine a reasonable . Inclined portion length and bevel angle α: slant angle of slope and the net angle of chopping. As mentioned above, the length of the bevel angle and the tilt of the dehydration by chopping a significant effect, increasing the length of the bevel angle and tilt, can improve the dehydration chopping board, but increases the pulsation strength, and thus, the paper machine must be speed, paper feed water treatment performance, chopping board installation location and other factors to determine reasonable. Chopping board for high-speed paper machine to the appropriate slope angle is smaller, usually with 1 ~ 3 °; while for low-speed paper machines (especially in the poor performance of the paper feed water treatment in the case) the chopping board bevel angle may be appropriate larger, generally available 2.5 ~ 4 °. For the case of a paper machine on the chopping board arrangement, to be used in the forming zone bevel angle smaller chopping board, and in the dewatering zone, you can use a large chopping board bevel angle. As the length of the inclined portion, generally 30 to 60 mm is appropriate, for forming zone can be shorter, and for the dewatering zone may be relatively longer. Functional use intensity and pulsation chopping board paper machine speed proportional to the square, and chopping board bevel angle and structural forms are also related. Chopping inclined angle increases, the pulsation strength is greater. Thus, with the improvement of the paper machine speed and slope angle increases, the amount of dehydration chopping board and a corresponding increase in the level of turbulence, it must be based on the improvement of the paper machine speed and slope angle increases, the amount of dehydration chopping board and turbulence level is improved, and therefore according to the paper machine speed and the product variety, quality requirements and other factors to determine a reasonable structure and geometry of the chopping board (chopping ramp angles, chopping length, etc.), the chopping rate to achieve optimum dehydration, spouting absolute minimum, resulting in promotion of paper forming the micro-turbulence, and the network load is reduced to a minimum traction purposes, in order to form good evenness, create conditions for good quality paper. Other notes chopping board process and mechanism of dehydration: chopping board is a fixed dewatering elements, dewatering performance is better, has been widely used in recent years.
