The felt suction box is a sealed structure. It will accelerate the drying of paper through vacuum pump suction, enhance the dehydration effect and paper forming. The two ends of the panel are equipped with adjustment devices to adjust the width of the paper suction port.
The felt suction box consists of a box body and a panel. Sun Hong uses stainless steel for the box body. The panel is divided into different materials. Sun Hong can provide panel materials such as high molecular polyethylene and ceramics. According to different paper machines, different paper types and different vehicle speeds, we can provide you with a panel suitable for you.
As an important dehydration equipment on the paper machine, during the production process, the press fine debris in the pulp (microfibers, colloids, etc.) is easy to adhere to the press felt, which can easily cause the press felt to be blocked and cause a serious decrease in water filtration performance. To ensure the normal use of the press felt, a felt suction box is set in the return journey of the press felt. The water absorption box can remove debris and excess water on the felt.
(1) Good self lubrication.
(2) Low friction coefficient, little damage to the press felt and a good service life.
(3) Easy to maintain and replace.
