Install double doctor blade holder in the center press section and net section rolls. Due to the centrifugal force, the water and fine fibers in the hole of the vacuum pressure roller will not flow out and adhere to the roller doctor blade to destroy its surface tension, remove some water and fine fibers, and form a tiny negative pressure after the doctor blade to remove the water in the hole. After the fiber is completely discharged, it is cleaned by the second doctor blade.
Prevent the net from regaining moisture and improve the dryness of the net. Experience has shown that after the vacuum roll uses pneumatic tire pressurized double doctor blade holder, the paper output dryness of the wire can be increased by 10-25%, and the investment cost can be recovered in a short time. At the same time, it can ensure the cleaning in the roll hole and the water content of the paper banner of the wire. Uniformity; the use of pneumatic tire pressure double doctor blade holder on the right roller of the press can thoroughly clean the water and fine fibers on the roller surface to prevent paper breaks and paper defects.
The double doctor blade holder is divided into ABCD double doctor blade holder and ABC CM type double doctor blade holder. We will design according to the customer’s specific situation and provide customers with choices.
