China Haihong Paper Mill Project
China Haihong Paper Mill Paper Machine
January 14, 2023–Meixin successfully provided an intelligent online fabric cleaning solution for a medium-to-large paper machine owned by China Haihong Paper Mill. The paper machine has a paper width of 3400mm and operates at a speed of 200 meters per minute, primarily producing tube base paper of 300-600 g/m². Meixin supplied the project with a wire cleaning system and a press felt cleaning system, comprehensively improving the paper machine's operational efficiency and paper quality.
1.Wire and Press Felt Cleaner
Function: Meixin's intelligent online wire and press felt cleaning system uses high-performance filtered clean water, which generates high-pressure water through a high-pressure pump station. The online cleaning machine is equipped with a high-efficiency cleaning head that traverses across the machine width. The cleaning head's movement is controlled by a PLC, and operators can set parameters via a visual touchscreen. The cleaning head sprays high-pressure water at a specific angle onto the paper machine clothing, achieving precise cleaning of the fabrics and ensuring normal, clean production.
Benefits:
Effective water and energy savings
Reduces or eliminates the need for chemical cleaning, more environmentally friendly
Completely solves the problem of uneven moisture distribution and felt cleaning streaks caused by local nozzle clogging
Better paper machine running performance and dewatering performance, helps increase machine speed
Dense cleaning method effectively removes regional contaminants and individual marks
Reduces web breaks in the forming and press sections
Significantly reduces water mist in the forming and press sections
Easy cleaning or nozzle replacement without shutdown
